[0004] Although the worktable in this slotting machine can rotate 360° and is suitable for processing a variety of products, the rotation of the worktable in the device is driven by a servo motor through a worm gear transmission mechanism, so the rotation angle of the worktable only depends on the drive of the servo motor, which has high requirements for the servo motor, and the rotation accuracy of the worktable is low, making it difficult to achieve thousandths of rotation. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a high-precision rotary worktable for a slotting machine to solve the problems in the prior art.

[0014] In one embodiment of the present invention, two groups of brakes are provided, which are respectively arranged on the left and right sides of the processing table, and four brake pads are evenly arranged around the axis of the processing table.

[0015] By adopting the above technical solution, the brake pads can be respectively arranged at the four vertices of the processing table, so that after the processing table is rotated at a larger angle by the driving mechanism, the brake pads can be located within the braking range of the brake.

[0016] In one embodiment of the utility model, the driving mechanism includes a servo motor arranged on the slotting machine body, a reducer arranged on the output end of the servo motor, a worm gear set connecting the reducer and the processing table, and a control box connected to the servo motor electrical signal, and the control box is connected to the brake electrical signal.
