The first outer positioning device and the first inner positioning device cooperate to position the left front end of the high worktable and the low worktable, and the second outer positioning device and the second inner positioning device cooperate to position the right front end of the high worktable and the low worktable.
[0007] As a further explanation of this technical solution:
[0008] Preferably, both the first external positioning device and the second external positioning device include a first cylinder located at the upper end, a second cylinder located at the lower end, and an external positioning plate arranged horizontally. The external positioning plate is vertically installed on the outer periphery of the left and right ends of the bracket. The first cylinder and the second cylinder are installed on the external positioning plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] Firstly, the present invention has a simple and reasonable structure. The layout of the external positioning device and the internal positioning device is reasonable, which can effectively position the front and rear sides of the worktable. The mounting base is a rectangular open shape, which facilitates the installation and maintenance of the cylinder. The buffer block can buffer the worktable moving backward and reduce impact. The cylinder guide rod and support rod improve the accuracy of the cylinder action and the structural strength of the mounting base.
[0017] Secondly, this utility model, through the cooperation of the external positioning device and the internal positioning device, can accurately position the high worktable and the low worktable, improve the accuracy of the worktable after repeated movement, greatly reduce working errors, and achieve high positioning accuracy and stability.
[0018] Thirdly, this utility model has strong compatibility.

The cylinder guide rod is used to guide the cylinder rods of the third and fourth cylinders, and further enhances their load-bearing capacity.
[0019] Fourth, when the high worktable reaches the designated position, the control device sends a signal, and the cylinders of the first external positioning device, the first internal positioning device, the second external positioning device, and the second internal positioning device are activated to position the high worktable. Meanwhile, the low worktable can work in the cutting area. After the low worktable finishes cutting, the control device sends a signal, and the cylinders of the first external positioning device, the first internal positioning device, the second external positioning device, and the second internal positioning device are retracted, exchanging worktables. This causes the low worktable to retract, and the high worktable to move to the cutting area. Once it reaches the designated position, the cylinders position the worktable. This cycle repeats, improving work efficiency.
[0020] Fifth, the first and second protective covers of this utility model can protect safety and prevent personnel from accidentally touching the positioning device, thus providing good safety protection. Attached Figure Description
