[0010] Beneficial Effects

[0011] The utility model provides a clamp for enhancing the turning rigidity of cage-type parts. Compared with the prior art, it has the following beneficial effects:

[0012] (1) The fixture for enhancing the turning rigidity of cage-type parts adopts a new clamping method that uses a positioning block and a clamping claw to simultaneously position and clamp the workpiece in the axial and radial directions. During the clamping process, the workpiece is automatically corrected to ensure that both ends of the workpiece are concentric. At the same time, the clamping position of the clamping claw is very close to the thread, which ensures the cutting rigidity during thread turning, thereby effectively avoiding thread turning tool vibration, improving the product qualification rate, and reducing tool loss.

[0013] (2) The clamp for enhancing the turning rigidity of the cage-type parts is driven by a motor to rotate the threaded rod. Under the guidance of the slider, the sleeve can move back and forth on the threaded rod, so that the sleeve drives the fixed block to move back and forth in the slide groove, thereby displacing the claw connected to the fixed block, which is convenient for clamping or disassembling the cage-type parts. The operation is simple and quick, and the work efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

The shell 9 is provided with three groups, which are evenly distributed on the outer surface of the chuck 1 in a ring shape, and the positions correspond to the positions of the claws 5 one by one, and a motor 10 is fixedly connected to the inner wall of the shell 9. The motor 10 is controlled by an external switch, and one end of the output shaft of the motor 10 is connected by a coupling. The shaft is fixedly connected with a threaded rod 11, and sliders 12 are slidably connected to both sides of the inner wall of the shell 9. A sleeve 13 is fixedly connected between the opposite sides of the two sliders 12, and one end of the sleeve 13 is provided with a threaded groove 14 adapted to the threaded rod 11. The other end of the sleeve 13 penetrates the chuck 1 and extends to the inside of the slide groove 7.

The positioning block 2 and the claw 5 are used to simultaneously position and clamp the workpiece axially and radially. The workpiece is automatically corrected during the clamping process to ensure that the two ends of the workpiece are concentric. At the same time, the clamping position of the claw 5 is very close to the thread, which ensures the cutting rigidity when turning the thread. On the contrary, the motor 10 drives the threaded rod 11 to reverse, which can drive the claw 5 away from the workpiece, making it easy to disassemble the workpiece. By screwing the bolt 6 out of the claw 5, the claw 5 can be removed from the pad 4. The claw 5 can be replaced accordingly according to the shape and size of the part to expand the scope of application.
