Detailed Implementation

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] like Figures 1 to 7 As shown, a grinding device for convenient grinding of connecting shafts includes: a worktable 1; a grinding assembly 2 connected to the worktable 1, wherein the grinding assembly 2 includes a mounting base 21, a connecting bracket 22 is provided on the mounting base 21, a first motor 23 movable relative to the connecting bracket 22 is provided on the connecting bracket 22, a grinding wheel 24 is provided on the output shaft of the first motor 23, and an adjustment group 25 is provided between the first motor 23 and the connecting bracket 22 to adjust their tilt angle; and a clamping assembly 3 connected to the worktable 1, wherein the clamping assembly 3 includes a base 31, a rotating seat 32 rotatable relative to the base 31, and the rotating seat... A clamping member 33 is connected to the 32 and can rotate with it. The clamping member 33 includes multiple clamping bars 331. A pressing member 34 that can move up and down relative to the clamping member 33 is provided inside the clamping member 33. A second motor 35 is provided on the worktable 1. The output shaft of the second motor 35 is connected to the pressing member 34 so that when the second motor 35 drives the pressing member 34 to slide downward, it can push the multiple clamping bars 331 so that the multiple clamping bars 331 abut against the inner wall of the connecting shaft. A positioning component 4 is connected to the worktable 1 and can clamp the outer wall of the connecting shaft. The positioning component 4 is also provided with ball bearings 41 that can assist the connecting shaft to rotate relative to it.

[0031] When it is necessary to grind the edge of the connecting shaft, align one end of the connecting shaft with the clamping member 33, then move the clamping member 33 so that it fits onto the outside of the connecting shaft. Then start the second motor 35. The output shaft of the second motor 35 drives the top pressing member 34 to move downward, so that the top pressing member 34 can push multiple clamping strips 331. The multiple clamping strips 331 abut against the inner wall of the connecting shaft and clamp one end of the clamping member 33. Then the positioning component 4 clamps the outer wall of the connecting shaft. When the rotating seat 32 rotates, the connecting shaft rotates accordingly. At this time, the connecting shaft rotates relative to the positioning component 4 through the ball bearing 41, which facilitates edge grinding. This makes it more convenient to grind the edge of the connecting shaft. Moreover, the first motor 23 and the connecting bracket 22 can change their angle through the adjustment group 25. The grinding wheel 24 can be adjusted according to the shape of the connecting shaft and the part that needs to be ground, making it more applicable.

[0032] The adjustment assembly 25 includes an arc-shaped groove 251 disposed on the connecting bracket 22. The front end of the first motor 23 is rotatably connected to the connecting bracket 22 around a first axis. A connecting member 252, which can extend into and move along the arc-shaped groove 251, is disposed in the middle of the first motor 23. The connecting member 252 is a screw. Through the cooperation of the arc-shaped groove 251 and the connecting member 252, the first motor 23 can flexibly rotate around the first axis on the connecting bracket 22, achieving precise angle adjustment.

[0033] The connecting bracket 22 is also connected to a positioning block 253, which has a sliding groove 2531. The first motor 23 is also connected to a rotating block 254 that can move relative to it. Part of the rotating block 254 extends into the sliding groove 2531. A third motor 255 is connected to the top of the positioning block 253. A rotating rod 256 that can pass through the sliding groove 2531 and rotate relative to it is connected to the output shaft of the third motor 255. The rotating rod 256 is threadedly connected to the rotating block 254. The rotating rod 256 is driven to rotate by the third motor 255, and the rotating block 254 is moved along the sliding groove 2531 by the threaded connection, so that the connecting piece 252 moves along the arc groove 251. This achieves precise position adjustment of the first motor 23, ensuring that the grinding wheel 24 can be accurately aligned with the grinding part of the connecting shaft, thus improving the grinding accuracy.

[0034] The clamping member 33 includes a base portion 332, on which multiple clamping bars 331 are connected. A gap 333 exists between each clamping bar 331. A first clamping block 3311 is provided at the top of each clamping bar 331. A sliding groove 334 is formed between the multiple clamping bars 331, allowing a pushing member to slide within it. The base portion 332 also has a through hole 3321 for the output shaft of the second motor 35 to move. The sliding groove 334 between the clamping bars 331 allows the pushing member to slide, while the through hole 3321 on the base portion 332 allows the output shaft of the second motor 35 to move, resulting in a compact overall structure with a small footprint. Furthermore, by driving the pushing member to slide within the sliding groove 334 via the second motor 35, the opening and closing of the clamping bars 331 can be achieved quickly.

[0035] The pressing member 34 is tapered, and each of the clamping bars 331 is provided with a first inclined surface 3312 that allows the pressing member 34 to press down, which facilitates pressing.

[0036] The base 31 includes multiple spaced-apart support blocks 311, each support block 311 having a protruding protrusion 312. The rotating seat 32 has an annular groove 321 within which the protrusion 312 can move. The multiple spaced-apart support blocks 311 can evenly distribute the weight of the rotating seat 32, ensuring that the rotating seat 32 remains stable during rotation. The mating structure of the protrusion 312 and the annular groove 321 provides precise guidance and limiting functions for the rotating seat 32, making rotation smoother.

[0037] The positioning component 4 includes a connecting plate 42 connected to the worktable 1. A connecting seat 43 is connected to the connecting plate 42. Clamping arms 44, which can rotate relative to the connecting seat 43, are provided at both ends of the connecting seat 43. Clamping arms 44 are provided with clamping grooves 441. A fourth motor 45 is also provided on the connecting seat 43. A linkage rod 46, which can move up and down with the fourth motor 45, is connected to the output shaft of the fourth motor 45. The linkage rod 46 is rotatably connected to each clamping arm 44. The clamping arms 44 can rotate relative to the connecting seat 43, and in conjunction with the fourth motor 45 driving the linkage rod 46 to move up and down, the clamping arms 44 can open and close, thereby flexibly clamping or releasing the connecting shaft. The clamping arms 44 at both ends are symmetrically arranged, and tightly clamp the outer wall of the connecting shaft through the clamping grooves 441, providing stable support.

[0038] The clamping arm 44 includes a movable rod 442 rotatably connected to a connecting seat 43. The lower end of the movable rod 442 is rotatably connected to a linkage rod 46. A second clamping block 443 is provided at the end of the movable rod 442. The second clamping block 443 is provided with a clamping groove 441, and a ball bearing 41 is provided on the groove wall of the clamping groove 441. The overall structure of the clamping arm 44 is simple, and the combination of the movable rod 442, the second clamping block 443, and the ball bearing 41 is straightforward and easy to manufacture and assemble. The second clamping block 443 at the end of the movable rod 442, with its clamping groove 441, can tightly fit against the outer wall of the connecting shaft, providing a stable clamping force.

[0039] The outer wall of the rotating seat 32 is provided with gear teeth 322, and the worktable 1 is equipped with a fifth motor 5. A drive gear 51, capable of meshing with the gear teeth 322, is connected to the output shaft of the fifth motor 5. By driving the drive gear 51 to mesh with the gear teeth 322 of the rotating seat 32 through the fifth motor 5, the rotation angle and speed of the rotating seat 32 can be precisely controlled. This precise control allows the connecting shaft to rotate evenly according to a preset program during the grinding process, resulting in more uniform grinding.

[0040] The rotating base 32 is also equipped with a positioning seat 6 that can support and abut the connecting shaft, and the clamping member 33 is located inside the positioning seat 6. The positioning seat 6 can accurately support and abut the connecting shaft, ensuring that the connecting shaft is in the correct position during clamping and grinding. The clamping member 33, located inside the positioning seat 6, further enhances the stable support for the connecting shaft and avoids shaking or displacement caused by unstable clamping.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
