Description

Technical Field

[0001] The invention relates to the technical field of mechanical fixtures, and in particular to a horizontal processing fixture for a robot joint reducer. Background Art

[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] Patent number 202020389518.X is a fixture for processing reducer housing. The device is provided with a forward and reverse motor, a threaded rod and a placement box. When the reducer housing needs to be processed, with the coordinated use of a limit groove, a limit block and a clamp, the forward and reverse motor rotates to drive the first bevel gear to rotate, and the rotation of the first bevel gear drives the second bevel gear and the threaded rod to rotate, thereby driving the movable plate and the clamp to move. When the clamp contacts the reducer housing with a clamp, the forward and reverse motor stops rotating and clamps the reducer housing between the clamps. With the coordinated use of a telescopic spring, a rubber block and a rubber pad, the clamping force of the reducer housing during the clamping process is improved, thereby ensuring the stability of the reducer housing during the clamping process. However, reducers have different specifications, and the telescopic springs of the device have a certain distance. When the specifications of the reducer are relatively small, unstable clamping will occur, reducing the practicality of the device.

[0004] The existing horizontal processing fixture of the robot joint reducer is not convenient for tightening reducers of different specifications during use, and the usual fixture uses two clamping plates for fixing, which is not convenient for fixing the reducer as a whole, which easily causes the device to be unstable and affects work efficiency.

[0005] Therefore, it is necessary to provide a new horizontal processing fixture for a robot joint reducer to solve the above technical problems. Summary of the invention
