TECHNICAL FIELD

The disclosure relates to the technical field of sawing tools, in particular to a sawing machine.

BACKGROUND

A sawing machine is a commonly used sawing tool. A cutting distance of a traditional sawing machine depends on a diameter of a saw blade. In order to extend the cutting distance without changing the saw blade specification, a sliding sawing machine has been developed currently, which obtains a longer cutting distance by moving a machine body mounted with the saw blade forward and backward relative to a workbench. However, because a saw blade slot on the workbench is required to be cooperated with the saw blade during cutting, the workbench must be increased synchronously to make a length of the saw blade slot on the workbench meet a requirement of the cutting distance. However, an increase in the size of the workbench may result in an increase in the overall volume of the sawing machine, which means a larger packaging size, a higher transport cost and a lower transport effect.

SUMMARY

An object of the present disclosure is to provide a sawing machine for solving the problem existing in the prior art that an extended cutting distance results in an increase in the overall volume of the sawing machine.

In order to achieve the above object, there is provided in the present disclosure a sawing machine including: a base, a main workbench, wherein the main workbench is rotatably connected to the base, an upper surface of the main workbench is provided with a chute, and the chute extends in a first direction and has an open end on an outer side surface of the main workbench; a machine body, wherein the machine body is slidably connected to the main workbench, a sliding direction of the machine body is parallel to the first direction, and the machine body is provided with a motor and a saw blade connected to the motor; an auxiliary workbench, wherein the auxiliary workbench is in an elongated shape and capable of slidably inserting into the chute and protruding out of the chute from the open end, an upper surface of the auxiliary workbench being provided with an elongated groove, the groove extends in the first direction, the groove and the chute are in communication in the first direction and form an extendable saw blade slot, the saw blade slot is elongated by sliding the auxiliary workbench toward outside of the chute, and the saw blade slot is shortened by sliding the auxiliary workbench toward inside of the chute.

In the present disclosure, the main workbench and the auxiliary workbench constitute a split-in workbench, and the chute and the groove constitute a split-in saw blade slot. The length of the overlapped portion of the chute and the groove is reduced by sliding the auxiliary workbench toward the outside of the chute, thereby increasing the length of the saw blade slot. The length of the overlapped portion of the chute and the groove is increased by sliding the auxiliary workbench toward inside of the chute, thereby decreasing the length of the saw blade slot. In actual use, the length of the saw blade slot is adjusted according to the required cutting distance, which is flexible and convenient. In the present disclosure, the saw blade slot can be used as long as the maximum length of the saw blade slot after being extended can reach the requirement of the maximum cutting distance, and it is not necessary to increase the main workbench to meet the requirement of increasing the cutting distance. When in packaging or transportation, the auxiliary workbench is slided into the chute to shorten the saw blade slot to a minimum length, or the auxiliary workbench is detached from the main workbench. Therefore, in the present disclosure, the cutting distance of the sawing machine can be extended, without increasing the overall volume of the sawing machine, increasing the packaging size, and increasing the transportation cost.
