BACKGROUND

After a wheel is turned and drilled, chips and emulsion may be left on the surface, and before air tightness detection, balance detection and run-out detection, the wheel needs to be cleaned and blown. In actual production, we often encounter the problems that the wheel is not cleaned thoroughly, aluminum chips remain and the like. A wheel cleaning and blowing device is urgently needed. By integrating cleaning and blowing, dry-wet separation is realized, and the wheel advances while rotating.

A wheel cleaning and blowing device and method are provided, which can be used for automatic continuous production. The device is novel in structure, accurate, efficient, and advanced in technology.

In one embodiment of the disclosure, a wheel cleaning and blowing device is composed of a frame, a lower servo motor, a bearing seat, a shaft, a bearing, a rotating disk, guide rails, a sliding table I, a sliding table II, a gear rack, an upper servo motor, a coupling, a servo motor I, a turntable I, an electric cylinder I, guide posts, a servo motor II, a turntable II, an electric cylinder II, flange plates, central posts, bolt hole posts, a concave support plate, positioning guide rails, a clamping cylinder, servo motors III, a left sliding plate, a positioning gear rack, a right sliding plate, positioning wheels, a vision sensor, a high-pressure water tank, a step water spray rack, nozzles, an air compressor, a step blowing rack, air outlets and a dry-wet separation plate.

The wheel cleaning and blowing device is composed of four systems: a wheel positioning system, which completes initial positioning of a wheel on a roller bed and finds the position of a valve hole; a wheel advancing and dry-wet conversion system, in which the wheel advances while rotating, thus completing double-station dry-wet conversion of the wheel; a high-pressure water cleaning system, which is matched with the advancing rotating wheel to clean the wheel; and a compressed air blowing system, which is matched with the advancing rotating wheel to blow the wheel uniformly.

The opening of the concave support plate is on the right side, the left side of the concave support plate is fixed on the side of the frame, and the four positioning guide rails are symmetrically mounted on the concave support plate. The left sliding plate and the right sliding plate are symmetrically mounted on the positioning guide rails and connected with each other via the positioning gear rack, the output end of the clamping cylinder is connected with the right sliding plate to control the left sliding plate and the right sliding plate to move synchronously, the servo motors III are fixed below the left sliding plate and the right sliding plate, and the positioning wheels are mounted at the output ends of the servo motors III. After the wheel enters the roller bed, the clamping cylinder is started to drive the left sliding plate and the right sliding plate to move synchronously, the wheel is initially positioned by the four positioning wheels, the servo motors III are started, the positioning wheels rotate, the wheel is driven to rotate, and the valve hole rotating to a position below the vision sensor is recognized. This is the wheel positioning system, which completes initial positioning of the wheel on the roller bed and finds the position of the valve hole.

The lower servo motor is mounted in the center of the bottom of the frame, the output end of the lower servo motor is connected with the rotating disk to control the rotating disk to rotate, the four guide rails are symmetrically mounted on the rotating disk, the sliding table I and the sliding table II are mounted on the guide rails in a bilaterally symmetric manner and connected with each other via the gear rack, the upper servo motor is fixed on the rotating disk, the output end of the upper servo motor is connected with a gear in the gear rack, and the sliding table I and the sliding table II move synchronously by driving the gear to rotate. The servo motor I is mounted on the sliding table I, and the output end thereof is connected with the turntable I to control the turntable I to rotate. The electric cylinder I is fixed on the turntable I, the output end thereof is connected with a flange plate to control the flange plate under the guidance of a guide post to ascend and descend, and this is a left station. The structure on the sliding table II is completely same as that on the sliding table I, the servo motor II is mounted on the sliding table II, and the output end thereof is connected with the turntable II to control the turntable II to rotate. The electric cylinder II is fixed on the turntable II, the output end thereof is connected with a flange plate to control the flange plate under the guidance of a guide post to ascend and descend, and this is a right station. The central posts and the bolt hole posts are fixed on the flange plates, the diameter of the central posts and the diameter, number and pitch diameter of the bolt hole posts are determined according to the produced wheel. After the wheel is positioned by the positioning system, the position of the valve hole is determined, and according to the included angles between bolt holes and the valve hole, the servo motor I is started to drive the flange plates to rotate, so that the bolt hole posts can be just located below the bolt holes of the wheel. The electric cylinder I is started to drive the flange plates to ascend from the initial low positions, meanwhile, the positioning wheels are reset, after the flange plates contact the flange face of the wheel and the bolt hole posts are inserted into the bolt holes, the wheel can be jacked to leave the roller bed, and the wheel on the sliding table I ascends to a preset high position. In the initial state, the flange plate on the sliding table I is at the preset low position, the flange plate on the sliding table II is at the preset high position, and the flange plate on the sliding table II descends to the low position while the flange plate on the sliding table I jacks the wheel to the high position. The upper servo motor is started to drive the sliding table I and the sliding table II to move synchronously to the center, i.e., the wheel moves forward from left to right, and when the wheel moves forward, the servo motor I is started to drive the wheel under the torque action of the bolt hole posts to rotate, so that the wheel advances while rotating. After the wheel is cleaned with high-pressure water, the lower servo motor is started to drive the rotating disk to rotate 180 degrees, the left station and the right station are exchanged, at the moment, the wheel enters the blowing system from the cleaning system, the cleaning system is separated from the blowing system by the dry-wet separation plate, and only a window through which the wheel can pass during station exchange is reserved. After the wheel enters the blowing system, the upper servo motor drives the sliding table I and the sliding table II to move synchronously to two ends, i.e., the wheel continues advancing while rotating and is blown. This is the wheel advancing and dry-wet conversion system, in which the wheel advances while rotating, thus completing double-station dry-wet conversion of the wheel.

The high-pressure water tank is located at the left top of the frame to discharge high-pressure water, and the step water spray rack is fixed on the frame. The step water spray rack has double steps symmetrically distributed 45 degrees, the top nozzle is used for cleaning the front center of the wheel, the nozzles on two sides of the first step are used for cleaning the front of the wheel, the high-pressure water enters the inner rim of the wheel from the window to clean the inner side of the wheel, the nozzles on two sides of the second step are used for cleaning the outer rim of the wheel, the wheel rotating while advancing can be cleaned in all directions under the action of centrifugal force, and this is the high-pressure water cleaning system.

The air compressor is located at the right top of the frame to discharge compressed air, the step blowing rack is same as the step water spray rack in structure and also has double steps symmetrically distributed 45 degrees, the top air outlet is used for blowing the front center of the wheel, the air outlets on two sides of the first step are used for blowing the front of the wheel, the air enters the inner rim of the wheel from the window to blow the inner side of the wheel, the air outlets on two sides of the second step are used for blowing the outer rim of the wheel, the wheel rotating while advancing can be blown uniformly, and this is the compressed air blowing system.

The working process of the wheel cleaning and blowing device is: according to the included angles between the valve hole and the bolt holes of the produced wheel, the circumferential positions of the bolt hole posts on the flange plates are adjusted, so that the bolt hole posts are just located below the bolt holes of the wheel; and in the initial state, the flange plate on the sliding table I is at the preset low position, the flange plate on the sliding table II is at the preset high position. After the wheel is positioned by the positioning system, cleaning and blowing are decomposed into four steps: step, the flange plate on the sliding table I ascends from the low position to the high position to jack the wheel to leave the roller bed, and the flange plate on the sliding table II descends from the preset high position to the low position; step, the upper servo motor is started to drive the sliding table I and the sliding table II to move synchronously to the center, i.e., the wheel moves forward from left to right, the servo motor I is started to drive the wheel to rotate, the wheel advances while rotating, the wheel entering the cleaning system is cleaned in all directions, the upper servo motor stops working after the wheel is cleaned, and the device enters a state of going to switch the left station and the right station; step, the lower servo motor is started to drive the rotating disk to rotate 180 degrees, the left station and the right station are exchanged, at the moment, the wheel enters the blowing system from the cleaning system, and the upper servo motor is restarted to drive the sliding table I and the sliding table II to move synchronously to two ends, i.e., the wheel continues advancing while rotating and is blown; and step, after the wheel is blown, the upper servo motor stops working, the idle sliding table II moves to the initial position of the left station, the sliding table I moves to the initial position of the right station, a manipulator takes the blown wheel away and puts it to a transfer roller bed, at the moment, the flange plate at the left station is at the low position, the flange plate at the right station is at the high position, the device is restored to the state of going to clean a wheel, next wheel is prepared for cleaning, and so on.
