[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-8As shown, a grinding and polishing device for shaft processing includes a main body 1. The main body 1 is equipped with a transmission component 2 and a grinding component 3. The transmission component 2 includes a first motor 21, a first transmission component 22, and a conveyor belt assembly 23. The first motor 21 is fixedly mounted on the main body 1, and the conveyor belt assembly 23 is mounted on the main body 1. The first transmission component 22 is installed between the first motor 21 and the conveyor belt assembly 23. The first motor 21 drives the first transmission component 22 to move the conveyor belt assembly 23. The conveyor belt assembly 23 is used to transport the shaft to be processed. The grinding component 3 is located in the middle of the conveyor belt assembly 23. The conveyor belt assembly 23 is equipped with a fixing component 4 for fixing the shaft to be processed. The fixing component 4 includes several fixing blocks 41 fixedly mounted on the conveyor belt assembly 23. Each fixing block 41 has several clamping holes 42. The conveyor belt of the conveyor belt assembly 23 has several clamping holes 42. Each clamping hole 42 corresponds to a through hole 231. Each clamping hole 42 of the fixing block 41 is provided with several evenly distributed sliding grooves 43. In this application, each clamping hole 42 contains two sliding grooves 43, and the two sliding grooves 43 are symmetrically arranged within the corresponding clamping hole 42 of the fixing block 41. Each sliding groove 43 opens towards the axial direction of the clamping hole 42. Each sliding groove 43 contains a sliding block 44. A first spring 45 abuts against the sliding groove 43 and the sliding block 44. The first spring 45 always has a tendency to push the sliding block 44 to move away from the conveyor belt. The sliding block 44 is used to clamp the shaft to be processed. As the sliding block 44 moves axially along the through hole 231, it also moves radially along the through hole 231. In this application, as the sliding block 44 moves from the side of the sliding groove 43 away from the conveyor belt assembly 23 towards the side of the sliding groove 43 closer to the conveyor belt, the distance between the sliding blocks 44 continuously decreases.

[0030] Therefore, when the fixing component 4 is located at the upper end of the conveyor belt, the slider 44 moves towards the side closer to the conveyor belt under the action of gravity, thereby causing the slider 44 to move towards the side closer to each other, so that the slider 44 contacts the outer periphery of the shaft to be processed, thereby achieving the function of clamping the shaft to be processed.

[0031] When the fixing component 4 is located at the lower end of the conveyor belt, the slider 44 moves away from the conveyor belt under the action of gravity, thereby causing the slider 44 to move away from each other, so that the slider 44 disengages from the outer periphery of the shaft to be processed, thereby realizing the function of lowering the clamped shaft.

[0032] It should be noted that a fixing cover is fixedly installed on the fixing block 41, and each fixing block 41 in this application is provided with four clamping holes 42.

[0033] Each sliding groove 43 includes, from the outside to the inside, a guide groove 431, a connecting groove 432, and a sliding groove 433. Each slider 44 includes a guide block 441, a clamping block 443, and a connecting block 442. The guide groove 431 and the sliding groove 433 are connected through the connecting groove 432. The guide block 441 and the clamping block 443 are connected through the connecting block 442. The guide block 441 is slidably fitted in the guide groove 431, the connecting block 442 is slidably fitted in the connecting groove 432, and the clamping block 443 is slidably fitted in the sliding groove 433. The clamping block 443 is used to clamp the shaft to be processed.

[0034] The guide block 441 described in this application is a counterweight block made of iron or steel, while the connecting block 442 and clamping block 443 can be made of lighter materials, such as aluminum or plastic, but can also be made of steel or iron.

[0035] Each clamping block 443 has an elastic pad 444 on its inner wall. The side of the elastic pad 444 away from the conveyor belt is farther from the axis of the clamping hole 42 than the side of the elastic pad 444 closer to the conveyor belt. Therefore, when the shaft to be processed is placed in, the deformation of the elastic pad 444 can achieve the function of clamping and fixing the shaft to be processed.

[0036] The grinding assembly 3 includes a second motor 31, a second transmission assembly 32, a mounting bracket 33, and a grinding cylinder 34. The second motor 31 and the mounting bracket 33 are respectively fixedly mounted on the main body 1. The grinding cylinder 34 is rotatably mounted on the mounting bracket 33. The second transmission assembly 32 is installed between the grinding cylinder 34 and the second motor 31.

[0037] In a further optimized configuration, the grinding assembly 3 includes a second motor 31 and four mounting brackets 33. The four mounting brackets 33 are divided into two groups, with two mounting brackets 33 in each group respectively mounted on both sides of the conveyor belt assembly 23. The two groups of mounting brackets 33 are evenly distributed along the conveying direction of the conveyor belt assembly 23. Each group of mounting brackets 33 is rotatably fitted with a grinding cylinder 34. The second motor 31 is driven by one of the grinding cylinders 34 through a second transmission assembly 32, and the two grinding cylinders 34 are driven by a third transmission assembly 38.

[0038] In this application, the first transmission component 22, the second transmission component 32 and the third transmission component 38 are all belt pulley drives.

[0039] The mounting bracket 33 is provided with a slide rail 331, which extends along the height direction of the mounting bracket 33. A sliding plate 35 is slidably fitted on the slide rail 331. A connecting hole is provided in the sliding plate 35. The grinding cylinder 34 is rotatably fitted in the connecting hole. An adjusting rod 36 is installed on the mounting bracket 33. The adjusting rod 36 is threadedly fitted with the sliding plate 35. The height of the sliding plate 35 can be adjusted by rotating the adjusting rod 36, so as to adapt to shafts of different lengths to be processed. A knob 361 is provided at the upper end of the adjusting rod 36. Rotating the knob 361 makes it easier to rotate the adjusting rod 36.

[0040] The adjusting rod 36 is fitted with a second spring 37 on its outer periphery. The adjusting rod 36 has a step 362. The second spring 37 is abutted between the step 362 and the sliding plate 35. The second spring 37 always has the tendency to push the sliding plate 35 downward, so that when the grinding cylinder 34 contacts the end of the shaft to be processed, the grinding cylinder 34 can always contact the end of the shaft to be processed, thereby ensuring the grinding effect.

[0041] The main body 1 has a storage cavity 10, and a collection basket 5 is placed in the storage cavity 10. The main body 1 has an opening and closing door 11, which is used to open and close the storage cavity 10. The upper end of the collection basket 5 has an opening 51, which is trumpet-shaped, so as to collect the processed shaft.

[0042] The bottom of the main body 1 is equipped with an adjustable height support base, which includes a telescopic rod and a shock-absorbing pad. The telescopic rod is fixedly installed at the bottom of the main body 1, and the shock-absorbing pad is fixedly installed at the bottom of the telescopic rod. The bottom of the main body 1 is provided with casters.

[0043] In practical use: The shaft to be processed is placed into the clamping hole 42, and the shaft to be processed contacts the elastic pad 444 on the clamping block 443, thereby pushing the clamping block 443 to move closer to the conveyor belt, thus reducing the distance between the clamping blocks 443, causing the elastic pad 444 to deform and tightly fit with the circumferential surface of the shaft to be processed, thereby achieving the function of fixing and clamping the shaft to be processed. The conveyor belt assembly 23 drives the shaft to be processed, so that the upper end face of the shaft to be processed contacts the grinding cylinder 34. The grinding cylinder 34 moves slightly upward, and the second spring 37 is compressed, thus making the grinding cylinder... 34 always maintains a tight fit with the upper end face of the shaft to be processed, thereby ensuring that the end of the shaft to be processed can be polished. When the shaft to be processed is polished, when the fixing component 4 that fixes the shaft to be processed is conveyed to the bottom of the conveyor belt, the clamping block 443, the connecting block 442 and the guide block 441 move away from the conveyor belt under the action of gravity, thereby causing the clamping block 443 to move away from each other, thereby disengaging the clamping block 443 from the processed shaft, and causing the processed shaft to fall into the collection basket 5, thereby realizing the function of polishing the processed shaft.
