Technical Field
[0001] This utility model relates to the field of speed reducer technology, and in particular to a precision machining and clamping device for speed reducer output shaft. Background Technology
[0002] A speed reducer is an independent mechanical component installed between a prime mover and a driven machine. Through gear transmission, worm gear transmission, or gear-worm gear transmission methods enclosed in a rigid housing, it achieves the function of reducing speed and increasing torque. In a mechanical transmission system, it plays a crucial role in matching speed and transmitting torque. The speed reducer output shaft is a key component in the speed reducer used for power transmission. It refers to the shaft that receives the reduced and increased torque power from the reduction mechanism and outputs it to the driven machine. Its function is to transfer the mechanical energy after the speed reducer reduces speed and increases torque to the load equipment. It is an important component connecting the speed reducer and the driven machine and realizing power output.
[0003] Early precision machining clamping equipment for reducer output shafts was relatively simple in structure. For example, some devices used manual adjustment to clamp the output shaft, which was cumbersome to operate and required a lot of manpower for clamping and disassembling. Today's precision machining clamping equipment for reducer output shafts has shown a high degree of advancement in design and function. Many devices use automation and intelligent technology to accurately clamp and position the reducer output shaft. However, existing devices, such as pressure plate type, require manual adjustment of bolts to control the clamping force, which is not only inefficient but also prone to uneven clamping force, causing workpiece deformation and reduced machining accuracy, resulting in reduced practicality and low work efficiency. Summary of the Invention
[0004] To overcome the above shortcomings, this utility model provides a precision machining and clamping device for the output shaft of a speed reducer, which aims to improve the problems of low efficiency, uneven clamping force, and unstable fixing in the existing technology.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a precision machining and clamping device for the output shaft of a speed reducer, comprising a base plate, a plurality of vertical plates fixedly connected to the top of the base plate, a plurality of arc-shaped plates fixedly connected between adjacent two vertical plates, a hollow cylinder fixedly connected between adjacent two arc-shaped plates, a hollow disc rotatably connected to the upper and lower ends of the hollow cylinder, a plurality of low fixing blocks fixedly connected to the top periphery of the hollow disc, a plurality of high fixing blocks fixedly connected to the top periphery of the hollow disc, and the upper and lower ends of the hollow cylinder fixedly connected to... The hollow cylinder is connected to multiple low fixed blocks, and multiple low fixed blocks are fixedly connected to the upper and lower ends of the hollow cylinder. Clamping rods are slidably connected between adjacent inner walls of two low fixed blocks. Clamping rods are slidably connected between adjacent inner walls of two high fixed blocks. Protrusions are fixedly connected to the outer walls of multiple hollow discs. Connecting columns are fixedly connected between adjacent inner walls of two protrusions.

A fixing mechanism is provided on the top of the base plate. The fixing mechanism is used to fix the output shaft.
[0006] The fixing mechanism includes a fixing plate fixed between two adjacent vertical plates. A support column is fixedly connected to the center of the top surface of the fixing plate. A limit column is fixedly connected to the top of the support column. One end of the limit column is threadedly connected to a forward threaded rod, and the other end of the limit column is threadedly connected to a reverse threaded rod. A slider is slidably connected to the outer wall of the forward threaded rod, and a slider is slidably connected to the outer wall of the reverse threaded rod. A clamp is fixedly connected to the top of a plurality of sliders. A support block is fixedly connected to the top of the base plate, and a motor is fixedly connected to the top of the support block. The output end of the motor is fixedly connected to the inner wall of the reverse threaded rod.
[0007] A support plate is fixedly connected to the bottom of the cylinder, and one end of the support plate is fixedly connected to the outer wall of the vertical plate.

[0012] As a further description of the above technical solution: The outer walls of the multiple sliders are provided with oil injection holes, and the outer walls of the multiple clamps are fixedly connected with magnetic blocks.
[0013] This utility model has the following beneficial effects: 1. In this utility model, the cylinder drives the connecting column to drive the hollow disc to rotate around the hollow cylinder, so that the high fixed block and the low fixed block linkage clamping rod can achieve coordinated clamping. With the auxiliary positioning of the arc plate, the effect of multi-directional stable clamping of the reducer output shaft is achieved. At the same time, the synchronous action of multiple clamping rods ensures that the clamping force is evenly distributed, improving the positioning accuracy and stability during precision machining.
[0014] In this invention, the forward and reverse threaded rods are driven by a motor to rotate synchronously, enabling the slider to drive the clamp to open and close precisely. Combined with the guiding effect of the limit post, this achieves the effect of auxiliary fixing and fine-tuning of the output shaft, which not only enhances the overall clamping stability but also adapts to the fixing requirements of output shafts of different specifications, thereby improving the versatility and clamping accuracy of the equipment.

[0020] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A support plate 13 is fixedly connected to the bottom of the cylinder 12. One end of the support plate 13 is fixedly connected to the outer wall of the vertical plate 3. A protective cover 14 is fixedly connected to the outer wall of the cylinder 12.

A nameplate 18 is fixedly connected to the top of the base plate 1. Specifically, the support plate 13 provides stable support for the cylinder 12 to prevent shaking during operation; the protective cover 14 is fixed to the outer wall of the cylinder 12 to protect the cylinder 12 and extend its service life; the limiting ring 15 is fixed to one end of the clamping rod 9 to limit the sliding stroke of the clamping rod 9 to prevent it from falling off the track; the rubber sleeve 16 is fixed to the outer wall of the clamping rod 9 to increase the friction with the output shaft and prevent damage to the workpiece surface during clamping; and the nameplate 18 is fixed to the top of the base plate 1 to mark equipment information for easy identification and management.
[0021] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 Multiple lifting rings 17 are fixedly connected to the outer wall of the base plate 1, rubber pads 19 are fixedly connected to the bottom of the base plate 1, multiple handles 20 are fixedly connected to the top of the base plate 1, a protective shell 21 is fixedly connected to the outer wall of the motor 209, oil injection holes 22 are opened on the outer wall of multiple sliders 206, and magnetic blocks 23 are fixedly connected to the outer wall of multiple clamps 207.

[0022] Working principle: When clamping the output shaft, the cylinder 12 extends and retracts, driving the connecting column 11 to displace the protrusion 10 connected to it, thereby driving the hollow disc 6 to rotate around the hollow cylinder 5. When the hollow disc 6 rotates, it drives the high fixed block 8 and the low fixed block 7 fixed on it to change position, so that the clamping rod 9 slides between the inner walls of the high fixed block 8 and the low fixed block 7. The clamping and releasing of the reducer output shaft is achieved by the sliding of the clamping rod 9. At the same time, the arc plate 4 at the top of the vertical plate 3 assists in positioning the output shaft. The multiple clamping rods 9 work together to ensure stable clamping of the output shaft during precision machining. When fixation is required, the motor 209 drives the reverse threaded rod 205 to rotate, which in turn drives the forward threaded rod 204 to rotate synchronously, causing the slider 206 to slide relative to and away from each other on the limit post 203 along the threaded rod. Then, the output shaft is assistedly fixed by the clamp 207. The fixing plate 201, the support post 202 and the support block 208 play a supporting and positioning role.
