[0002] A grinding machine is a mechanical device used to process the surface of gear shafts. It can be used to perform high-precision machining on steering gear shafts, improving their dimensions, surface roughness, and fit. This is crucial for ensuring the normal operation of the steering system and extending its service life.

[0003] Patent application CN212735312U discloses a bearing grinding machine designed to solve the problem of stable clamping of bearings of different sizes. The key technical points are: it includes a frame, a worktable, and an adjustable grinding mechanism. The worktable is rotatably connected to the frame. A power structure for driving the worktable to rotate is fixedly connected to the bottom of the frame. A chassis is fixedly connected to the worktable, and a tooling structure for clamping different bearing rings is fixedly connected to the chassis. The tooling structure includes an adjusting rod, an adjusting block, a sliding block, and several clamping blocks. The adjusting rod is rotatably connected to the chassis.

The base plate 1 is equipped with a fixing component. The bottom of the base plate 1 has a mounting groove 9. The bottom of the base plate 1 is fixedly connected to a mounting plate 10. The top of the base plate 1 has movable grooves 11 at equal intervals. The bottom of the movable plate 31 is fixedly connected to two mounting rods 12. The bottom of the two mounting rods 12 extends into the mounting groove 9 and is fixedly connected to a connecting plate 13. The top of the connecting plate 13 is slidably connected to the top of the inner wall of the mounting groove 9. An adjustment component is provided inside the mounting groove 9. The adjustment component is used to drive the connecting plate 13 to move. A support component is provided on the top of the base plate 1.

[0026] The adjustment assembly includes a positioning rod 14, which is fixedly connected to the top of the inner wall of the mounting groove 9. A first connecting rod 15 is rotatably connected to the outer side of the positioning rod 14, and a second connecting rod 16 is rotatably connected to the bottom of the first connecting rod 15. The top of the second connecting rod 16 is rotatably connected to the bottom of the connecting plate 13.

[0027] Two sliding rods 17 are slidably connected to one side of the base plate 1. Fixing plates 18 are fixedly connected to both sides of the two sliding rods 17. One side of one fixing plate 18 is fixedly connected to one side of one connecting plate 13. A second telescopic rod 19 is provided on the top of the base plate 1. A connecting block 20 is fixedly connected to the top of one fixing plate 18. One end of the second telescopic rod 19 is fixedly connected to one side of the connecting block 20.

[0028] A collar 21 is fixedly connected to the outside of the slide rod 17, and a spring 22 is provided on the outside of the slide rod 17;

[0029] The fixing component includes two fixing blocks 23, which are fixedly connected to the top and bottom of the sleeve 7 respectively. The fixing blocks 23 have a receiving groove 24 inside, and a threaded rod 25 is threadedly connected inside the fixing blocks 23. One end of the threaded rod 25 extends into the receiving groove 24 and is rotatably connected to a pressing block 26.

[0030] The support assembly includes a housing 27, which is fixedly connected to the top of the base plate 1. A groove 28 is provided on the top of the housing 27. A support plate 29 is slidably connected inside the groove 28. A lead screw 30 is rotatably connected inside the groove 28. The outer side of the lead screw 30 is threadedly connected to the inside of the support plate 29.

[0031] In the above technical solution, considering that the grinding machine clamps the shaft vertically for grinding, different shafts have different lengths. For longer shafts, vertical clamping may cause the shaft to wobble during rotation, affecting the grinding accuracy and reducing product quality. To solve this problem, the specific operation is as follows: By setting an adjustment component, a fixing component, and a support component, the length of the steering gear shaft to be ground is determined. The lead screw 30 is rotated to move the support plate 29 within the groove 28, adjusting the distance between the two support plates 29. Then, the steering gear shaft is placed in the support plate 29. The second telescopic rod 19 is activated to extend, causing the connecting block 20 to move to one side, and also causing the fixing plate 18 and the sliding rod 17 to move in the same direction. Because one of the fixing plates... 18 is fixedly connected to one of the connecting plates 13, which will drive one set of movable plates 31, mounting rods 12 and connecting plates 13 to move. Then, by using the transmission action of positioning rod 14, first connecting rod 15 and second connecting rod 16, another set of movable plates 31, mounting rods 12 and connecting plates 13 will move synchronously. In this way, the turntable 6 will abut against one end of the steering gear shaft, and the other end will abut against the inside of the sleeve 7 to fix the steering gear shaft. Then, the two threaded rods 25 are rotated to drive the extrusion block 26 to move out from the inside of the receiving groove 24 and abut against the outside of the steering gear shaft to further fix it. Then, the first telescopic rod 4 is started to drive the grinding machine 5 to move downward and close to the steering gear shaft. The motor 8 is started to drive the sleeve 7 to rotate smoothly, thereby driving the steering gear shaft to rotate. Then the grinding machine 5 is started to grind it. By adjusting and supporting the components, shafts of different lengths can be flexibly adapted. The fixing component clamps the steering gear shaft, reducing the shaking of the shaft during rotation and improving the uniformity and accuracy of grinding. The two movable plates 31 clamp synchronously to ensure that the shaft is firmly clamped during the clamping process, making it less prone to slipping or shaking, thus improving the machining accuracy. The clamping position can also be flexibly adjusted according to the shaft length to adapt to diverse workpiece sizes and enhance the versatility of the equipment.

[0032] Reference Figures 1 to 5 In a preferred embodiment, the first telescopic rod 4, the grinding machine 5, the motor 8, and the second telescopic rod 19 are electrically connected to an external controller.

[0033] Working principle: In use, the length of the steering gear shaft is ground as needed. By rotating the lead screw 30, the support plate 29 is moved inside the groove 28. The distance between the two support plates 29 is adjusted, and then the steering gear shaft is placed in the support plate 29. The second telescopic rod 19 is activated to extend, causing the connecting block 20 to move to one side, and causing the fixed plate 18 and the sliding rod 17 to move in the same direction. Because one of the fixed plates 18 is fixedly connected to one of the connecting plates 13, this will drive one set of movable plates 31, mounting rod 12 and connecting plate 13 to move. Then, by using the transmission action of the positioning rod 14, the first connecting rod 15 and the second connecting rod 16, the other set of movable plates... 31. The mounting rod 12 and the connecting plate 13 move synchronously, so that the turntable 6 will abut against one end of the steering gear shaft and the other end will abut against the inside of the sleeve 7 to fix the steering gear shaft. Then, the two threaded rods 25 are rotated to drive the extrusion block 26 to move out from the inside of the receiving groove 24 and abut against the outside of the steering gear shaft to further fix it. Then, the first telescopic rod 4 is started to drive the grinding machine 5 to move downward and close to the steering gear shaft. The motor 8 is started to drive the sleeve 7 to rotate smoothly, thereby driving the steering gear shaft to rotate. Then the grinding machine 5 is started to grind it.
