Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a device for grinding the surface of a rotating shaft. Background Technology

[0002] In the field of mechanical manufacturing, shafts are key components of various rotating machinery. Their surface quality directly affects the operating performance, service life and reliability of the machinery. In order to meet the requirements of high precision, low friction and wear resistance, shafts usually need to undergo fine surface grinding after processing to remove surface burrs and oxide layers and obtain ideal surface roughness.

[0003] In the existing technology, there are many types of devices for grinding the surface of rotating shafts, but they generally have some shortcomings. For example, during the grinding process, the fit between the grinding parts and the outer wall of the rotating shaft is often not ideal, especially when dealing with rotating shafts of different diameters or with slight deformation. It is difficult to achieve adaptive adjustment of the grinding strip, resulting in uneven distribution of grinding pressure, which in turn affects the uniformity and consistency of the grinding effect. In addition, some devices have complex structures and are inconvenient to operate. Furthermore, the debris generated during the grinding process is easy to accumulate inside the device, which not only affects the performance of the device but also increases the burden of cleaning and maintenance. These problems limit the versatility and grinding quality of existing rotating shaft grinding devices.

[0004] Therefore, this utility model proposes a rotating shaft surface grinding device to overcome the shortcomings of the prior art. Utility Model Content

[0010] Preferably, the adaptive grinding mechanism further includes a tension spring, with its two ends connected to the inner walls of the grinding strip and the rotating ring, respectively, for pulling the grinding strip back to its initial position when the cylinder retracts.

[0011] Preferably, the rotating ring has holes for discharging debris, so that the waste generated during the grinding process can be discharged in a timely manner.

[0012] Preferably, the shaft surface polishing device further includes a housing, which covers the drive assembly, bevel gear and bevel gear ring to provide protection for the internal transmission components.

[0013] Preferably, there are two cylinders symmetrically arranged inside the rotating ring, so that the grinding strip can be more evenly attached to the surface of the rotating shaft by applying force symmetrically.

[0015] Preferably, the other end of the connecting rod is rotatably connected to the middle of the grinding strip, which helps to achieve more effective force transmission and grinding strip bending control.

[0016] This utility model has the following beneficial effects: 1.

[0021] 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.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a rotating shaft surface grinding device, which includes a base 1 and a fixed cylinder 3 fixedly connected to the top of the base 1. The base 1 serves as the supporting foundation for the entire device to ensure the stability of the equipment during operation. The fixed cylinder 3 is used to accommodate and position the rotating shaft to be ground, and its connection with the base 1 ensures the stability of the rotating shaft when it is fed in.

[0023] The rotating shaft surface grinding device also includes a rotating ring 5 and a transition cylinder 7 disposed outside the fixed cylinder 3. The transition cylinder 7 and the rotating ring 5 are connected by a connecting flange 4. A bevel gear ring 6 is fixedly connected to the outer wall of the connecting flange 4. The bevel gear ring 6 meshes with a bevel gear 9. The bevel gear 9 is driven to rotate by the drive assembly 8, thereby driving the rotating ring 5 to rotate synchronously. The outer shell 10 covers the drive assembly 8, the bevel gear 9 and the bevel gear ring 6 to protect the internal components of the outer shell 10.

[0024] The rotating ring 5 is equipped with an adaptive grinding mechanism 2, which is the core component for achieving efficient grinding of the rotating shaft surface. The adaptive grinding mechanism 2 includes a cylinder 201, a horizontal plate 202, a connecting rod 203, and a grinding strip 204. The cylinder 201 is fixed to the inner wall of the rotating ring 5, and its output end is connected to the horizontal plate 202. One end of the connecting rod 203 is rotatably connected to the horizontal plate 202, and the other end is rotatably connected to the grinding strip 204. The grinding strip 204 is the component that directly contacts the rotating shaft surface for grinding. When the cylinder 201 pushes the horizontal plate 202, the grinding strip 204 can move closer to the center of the rotating shaft and fit against the outer wall of the rotating shaft through the action of the connecting rod 203.

[0025] In a preferred embodiment, in order to achieve adaptive fitting and polishing of the rotating shaft surface, the polishing strip 204 is preferably a flexible polishing strip 204, and the other end of the connecting rod 203 is rotatably connected to the middle of the polishing strip 204. The structure allows the polishing strip 204 to bend and tightly wrap around the outer wall of the rotating shaft when the cylinder 201 pushes the horizontal plate 202 and then pushes the connecting rod 203.

[0026] As a preferred embodiment, please refer to Figure 4 In order to improve the stability of the movement of the horizontal plate 202 and ensure that the grinding strip 204 moves smoothly close to or away from the rotating shaft, the adaptive grinding mechanism 2 also includes a stabilizing column 205. The stabilizing column 205 is fixed inside the rotating ring 5. The horizontal plate 202 is provided with a matching through hole, so that the horizontal plate 202 slides and engages with the stabilizing column 205.

[0027] As a preferred embodiment, please refer to Figure 4 In order to make the grinding strip 204 more evenly stressed and improve the bonding effect, the cylinders 201 are preferably two symmetrically arranged in the rotating ring 5. The two cylinders 201 act together on the grinding strip 204 through their respective cross plates 202 and connecting rods 203.

[0028] As a preferred embodiment, please refer to Figure 4 In order to enable the polishing strip 204 to automatically detach from the rotating shaft and reset after polishing, the adaptive polishing mechanism 2 also includes a tension spring 206. The two ends of the tension spring 206 are respectively connected to the inner wall of the polishing strip 204 and the rotating ring 5. When the cylinder 201 retracts and removes the thrust, the elastic force of the tension spring 206 pulls the polishing strip 204 back to the initial state.

[0029] As a preferred embodiment, please refer to Figure 3 In order to remove the dust and debris generated during the polishing process in a timely manner and prevent accumulation, holes 207 are provided on the rotating ring 5.

[0030] As a preferred embodiment, please refer to Figure 1In order to protect the internal transmission components and prevent interference from external debris, the device also includes a housing 10, which covers the drive assembly 8, bevel gear 9 and bevel ring 6.

[0031] Working principle: When grinding the shaft, the shaft is fed into the fixed cylinder 3 through the open end, and then the bevel gear 9 is driven to rotate by the drive assembly 8. The fixed cylinder 3 is fixed on the top of the base 1 to ensure the stability of the fixed cylinder 3. A connecting flange 4 and a rotating ring 5 are provided between the transition cylinder 7 and the fixed cylinder 3. The bevel gear ring 6 fixed on the outer wall of the connecting flange 4 on one side meshes with the bevel gear 9, that is, the bevel gear 9 and the rotating ring 5 rotate synchronously. The adaptive grinding mechanism 2 inside the rotating ring 5 grinds the shaft. The outer shell 10 protects the internal components. When the rotating shaft is fed into the fixed cylinder 3 and reaches the middle of the rotating ring 5, the cylinder 201 is activated. The cylinders 201 on both sides push the horizontal plate 202. The stabilizing column 205 ensures the stable displacement of the horizontal plate 202, causing the grinding strips 204 on both sides to move closer to the middle. When the grinding strips 204 touch the rotating shaft, the cylinder 201 continues to push the horizontal plate 202. At this time, the connecting rod 203 rotates, and the grinding strips 204 bend to fit tightly against the outer wall of the rotating shaft. The rotating ring 5 rotates to grind the outer wall of the rotating shaft. After grinding is completed, the cylinder 201 retracts, and the tension spring 206 tightens the grinding strips 204, so that the grinding strips 204 are taut and reset. The hole 207 can discharge the debris and waste generated during grinding.
