[0002] The reducer is a reduction transmission device between the prime mover (motor) and the working machine. Its function is to match the speed and transmit torque between the prime mover and the working machine or actuator. It is a relatively precise mechanical device whose purpose is to reduce the speed and increase the torque. It is widely used in modern machinery.

Two left-right symmetrical first sliders 5 are arranged below the supporting plate 3. The first sliders 5 are slidably connected to the first guide rail 4. The first guide rail 4 is fixedly installed on the workbench 1. The first guide rail 4 is arranged in a front-to-back direction so that the supporting plate 3 can slide in the front-to-back direction so that the supporting plate 3 can be positioned at the loading station at the front end of the guide rail and the press-fitting station at the rear end. Transfer between workstations, the support plate 3 is used to place the shaft seat workpiece 8. When the support plate 3 is at the loading station, the worker can place the shaft seat workpiece 8 and pre-set the shaft ring to be pressed in the top countersunk hole thereof. The lifting drive assembly 2 is connected with a pressure head 7. The lifting drive assembly 2 specifically includes a hydraulic cylinder and a guide rod and guide sleeve assembly, etc. The bottom end of the lifting rod of the hydraulic cylinder is connected to a pressing plate, and a pressure head 7 is detachably installed under the pressing plate. The pressure head 7 is adapted to the shaft ring workpiece 9. The lifting drive assembly 2 can press the shaft ring workpiece 9 into the countersunk hole of the shaft seat workpiece 8 through the pressure head 7 at the press-fitting station to complete the press-fitting.

[0017] The shaft seat is provided with two positioning holes 10 penetrating up and down, and the positioning mechanism 6 includes two positioning rods 11 corresponding to the positioning holes 10, a lifting cylinder 12, a lifting plate 13, a second guide rail 14, and a second slider 15. The positioning mechanism 6 is used to insert the two positioning rods 11 into the positioning holes 10 when the supporting plate 3 moves to the press-fitting station to complete the positioning. Specifically, the lifting cylinder 12 is located below the supporting plate 3, and the piston rod of the lifting cylinder 12 is vertically upward and fixedly connected to the lifting plate 13. The lifting plate 13 Two cantilevers are provided, each cantilever is fixedly connected to a positioning rod 11, and a second slider 15 is connected to the rear side of the lifting plate 13, and the second slider 15 is slidably connected to the second guide rail 14, and the second guide rail 14 is arranged in parallel with the piston rod of the lifting cylinder 12. The lifting cylinder 12 can drive the lifting plate 13 to move up and down, and the cooperation between the guide rail and the slider can play a precise guiding role to ensure the accuracy of the lifting and lowering movement. Before pressing, the lifting plate 13 is lifted and the positioning rod 11 is inserted into the positioning hole 10 of the shaft seat workpiece 8 to complete precise positioning.

[0018] Furthermore, a limit assembly is also provided on the workbench 1, and the limit assembly includes a fixed seat 16, and the fixed seat 16 is connected to a limit rod 17 and a support rod 18.
