Description
Technical Field
[0001] The present application relates to the technical field of bearing processing equipment, and in particular to a high-gloss bearing polishing device and a polishing process thereof. Background Art
[0002] Bearings are a crucial component in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. High-quality bearings, as the name suggests, are characterized by a high surface finish. Bearings with a surface roughness no greater than Ra0.4 are typically considered high-quality bearings.
[0003] During the processing of high-gloss bearings, the surface of the bearings needs to be polished to achieve the required surface roughness. Currently, a drum polisher is commonly used to polish the surface of bearings. After multiple bearings and polishing material are placed in the drum, the drum is rotated so that the bearings and polishing material move inside the drum. During this movement, the bearing surface comes into contact with the polishing material, which grinds the bearing surface and achieves polishing.
[0004] However, when the bearing is polished by the polishing material inside the drum, it is easily affected by its own gravity and sinks to the bottom. The bearing that sinks to the bottom is not easy to move with the rotation of the drum. Therefore, the frequency of contact between the bottom of the bearing and the polishing material is lower than that of other parts of the bearing. In order to ensure that the surface roughness of the bearing meets the requirements, the polishing time required for the bearing surface will be longer. The existing drum polishing machine has low polishing efficiency for bearings and urgently needs to be improved. Summary of the Invention
[0005] In order to improve the problem of low polishing efficiency of high-brightness bearings, the present application provides a high-brightness bearing polishing device and a polishing process thereof.
[0006] On the one hand, the present application provides a high-gloss bearing polishing device, which adopts the following technical solution:
[0007] A highlight bearing polishing device includes a body, a roller and a first driving member, the roller is rotatably connected to the body, the rotation axis of the roller is horizontal, the first driving member is arranged on the body, and the first driving member can drive the roller to rotate, and also includes a baffle for intercepting the bearing movement, the baffle is connected to the body; the interior of the roller has a cavity and the cross-section of the cavity is a regular polygon, the roller is provided with an opening, the opening is communicated with the cavity, and a door cover for controlling the opening and closing of the opening is provided on the outside of the roller; the baffle is located in the cavity, and when the roller rotates, the bearing contacts the baffle, and the baffle can guide the moving bearing to flip.
[0008] By adopting the above technical solution, after the bearing to be polished and the polishing material are put into the cavity through the opening, the first driving member drives the roller to rotate, which will drive the bearing and the polishing material to move. During the movement of the bearing, one end of the bearing first contacts the baffle, and the baffle prevents the end of the bearing from continuing to move in the direction of rotation of the roller, while the other end of the bearing will continue to move driven by the rotation of the roller, so that the bearing continues to move and flips after contacting the baffle; during the process of the bearing being polished by the polishing material, the bearing will repeatedly move and flip, so that the effect of the bearing surface being polished by the polishing material is more uniform, thereby improving the polishing efficiency of the polishing equipment for the bearing.
[0009] Optionally, an anti-slip pad is further included, which is located in the cavity and covers the cavity wall of the cavity.
[0010] By adopting the above technical solution, after the bearing to be polished is put into the cavity, the bearing will contact the anti-slip pad. The friction between the anti-slip pad and the bearing is relatively large, which can improve the effect of the roller rotation driving the bearing movement. At the same time, it can make the bearing easier to flip after contacting the baffle, reducing the probability of the bearing being unable to flip due to slipping due to direct contact with the cavity wall.
[0011] Optionally, the anti-slip pad has a plurality of elastic columns, which are evenly spaced along the rotation axis of the roller, and the spacing between adjacent elastic columns is not less than the particle size of the polishing material.
[0012] By adopting the above technical solution, after the bearing to be polished and the polishing material are put into the cavity, several elastic columns support the bearing to prevent the bottom of the bearing from completely contacting the anti-slip pad; at the same time, space is left between adjacent elastic columns for the polishing material to move through. When the polishing material moves through the space between adjacent elastic columns, it can polish the bottom of the bearing, thereby increasing the frequency of contact between the bottom of the bearing and the polishing material, making the polishing material polish the bearing surface more uniform, thereby further improving the polishing efficiency of the polishing equipment for the bearing.
[0013] Optionally, the elastic columns in two adjacent rows are staggered.
[0014] By adopting the above technical solution, the space left between several adjacent elastic columns can form more diverse routes for the polishing material to move through, so that the polishing material can move smoothly under the bearing, thereby improving the polishing effect of the polishing material on the bottom of the bearing.
[0015] Optionally, when the drum rotates, a distance is maintained between the baffle and the elastic column.
[0016] By adopting the above technical solution, the baffle will not contact the elastic columns during the rotation of the drum, thereby avoiding damage to the elastic columns caused by the contact between the two, and avoiding the baffle from forming resistance to the rotation of the drum after the contact between the two, thereby extending the service life of the polishing equipment; in addition, when the polishing material moves with the rotation of the drum, more polishing material can move through the gap between the baffle and the elastic columns, so that more polishing material can pass through the obstruction of the baffle during the movement, and has greater potential energy, so that it can move back to the bottom at a faster speed, thereby having a better polishing effect on the bottom of the bearing.
[0017] Optionally, one side of the baffle has a curved surface, and when the drum rotates, the bearing moves and contacts the curved surface.
[0018] By adopting the above technical solution, after the drum rotates and drives the bearing to move, one end of the bearing contacts the arc surface. The arc surface can guide the bearing to continue to move and then flip over, reducing the difficulty of the bearing flipping, so that the bearing can successfully complete the flipping under the interception of the baffle.
[0019] Optionally, the baffle is provided with a plurality of through holes for the polishing material to pass through.
[0020] By adopting the above technical solution, after the roller rotates and drives the polishing material to move, the polishing material can pass through the through hole and the obstruction of the baffle, and has greater potential energy, so that it can move back to the bottom at a faster speed, thereby having a better polishing effect on the surface of the bearing.
[0021] Optionally, there is an arc-shaped transition surface between adjacent cavity walls.
[0022] By adopting the above technical solution, the transition surface can reduce the resistance encountered by the bearing and the polishing material when passing through this position, and reduce the energy loss of the bearing and the polishing material when moving through the junction of the adjacent cavity walls, so that the bearing can be polished more fully by the polishing material during the movement of the bearing and the polishing material; and it can reduce the probability of the bearing getting stuck at the junction of the adjacent cavity walls during the movement, so that the bearing can move smoothly until it contacts the baffle and flips over.
[0023] Optionally, a second driving member is further included, wherein the second driving member is arranged on the machine body, and the second driving member can drive the baffle to rotate, and the rotation axis of the baffle is parallel to the rotation axis of the drum.
[0024] By adopting the above technical solution, the second driving member is controlled to drive the baffle to rotate, so that the position where the bearing flips can be adjusted. At the same time, the size of the space between the baffle and the roller for the polishing material to move through can be adjusted, thereby making it convenient for the staff to adjust the position of the baffle according to the quality and shape of bearings of different models, so that the polishing equipment has a high applicability to bearings of different models.
[0025] On the other hand, the present application also provides a polishing process for highlighting bearings, which adopts the following technical solution:
[0026] A polishing process for a high-gloss bearing, based on the above-mentioned high-gloss bearing polishing equipment, comprises the following steps:
[0027] S1, putting the bearing to be polished and the polishing material into the cavity;
[0028] S2. Controlling the first driving member to drive the drum to rotate, causing the bearing and the polishing material to move in the cavity, and polishing the bearing surface;
[0029] S3. After the bearing polishing process is completed, the polishing material is first poured out from the cavity, and then the polished bearing is poured out from the cavity.
[0030] By adopting the above technical solution, the time required to polish the bearing surface to the required requirements can be shortened, that is, the time required for the polishing process can be shortened, thereby improving the production efficiency of high-brightness bearings.
[0031] In summary, this application has at least one of the following beneficial effects:
[0032] 1. When the roller rotates and drives the bearing to move, the bearing can flip over after contacting the baffle, so that the bearing surface can be evenly polished by the polishing material, thereby improving the polishing efficiency of the polishing equipment on the bearing surface;
[0033] 2. As the roller rotates and drives the bearing and polishing material to move, the polishing material can fully polish the bottom of the bearing, so that the bearing surface can be polished evenly, further improving the polishing efficiency of the polishing equipment on the bearing surface;
[0034] 3. After rotating the baffle to adjust its position, the polishing equipment can be used to polish bearings of different models. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is combined with Figure 1-5 This application is described in further detail.
[0042] The embodiment of the present application discloses a high-brightness bearing polishing device.
[0043] Reference Figure 1 and Figure 2 The polishing equipment includes a body 1, a roller 2, a first driving member 3, a baffle 4 and a second driving member 5. The roller 2 and the baffle 4 are both rotatably connected to the body 1, and the rotation axes of the two are horizontal and coincident; the baffle 4 is located inside the roller 2, the first driving member 3 is used to drive the roller 2 to rotate, and the second driving member 5 is used to drive the baffle 4 to rotate; after multiple bearings to be polished and a certain amount of polishing material are put into the roller 2, the second driving member 5 is controlled according to the model of the bearing to drive the baffle 4 to rotate to a suitable position, and then the first driving member 3 is controlled to drive the roller 2 to rotate. During the rotation of the roller 2, the multiple bearings and polishing materials inside the roller 2 will move a distance in the same direction as the rotation direction of the roller 2 under the action of inertia, and then move back to the bottom of the roller 2 under the action of their own gravity, and this cycle is repeated; after the bearing rotates with the roller 2 until it contacts the baffle 4, the bearing will flip over; during the rotation of the roller 2, the polishing material contacts the moving bearing during movement and polishes the surface of the bearing, so that the bearing is polished during the rotation of the roller 2. In this embodiment, since the polishing material is a commonly used material in this field, it is not specifically limited here.
[0044] The machine body 1 is used to fix the polishing apparatus on the ground. It has two bases 11 spaced apart and located at either end of the machine body 1. A first drive member 3 and a second drive member 5 are fixedly mounted on the tops of the two bases 11, respectively. The roller 2 and the baffle 4 are positioned between the two bases 11 after installation. In this embodiment, both the first drive member 3 and the second drive member 5 are preferably stepper motors, and both the first drive member 3 driving the roller 2 and the second drive member 5 driving the baffle 4 are unidirectional.
[0045] Reference Figure 2 and Figure 3 One end of the drum 2 is fixedly connected to the first drive member 3, and the other end of the drum 2 is rotatably connected to the base 11. The cross-section of the drum 2 is a regular polygon, and the rotation axis of the drum 2 coincides with its own centerline of symmetry. The drum 2 has a cavity 21 inside, and the cross-section of the cavity 21 is similar to the cross-section of the drum 2. The circumferential wall of the cavity 21 has an arc-shaped transition surface 24 between adjacent planes. In this embodiment, the cross-section of the drum 2 is preferably a regular hexagon, and the cross-section of the cavity 21 is a regular hexagon with rounded corners.
[0046] Reference Figure 4 and Figure 5 Drum 2 also has an opening 22 that communicates with cavity 21, allowing bearings and polishing material to enter and exit cavity 21. A door 23 is also mounted on the surface of drum 2 to control the opening and closing of opening 22. When the bearings to be polished and the polishing material need to be placed into cavity 21, drum 2 rotates until opening 22 is at the top of drum 2. When the polished bearings and the polishing material need to be removed from cavity 21, drum 2 rotates until opening 22 is at the bottom of drum 2. Door 23 opens opening 22 both when the bearings to be polished and the polishing material need to be placed into cavity 21 and when the polished bearings and the polishing material need to be removed from cavity 21. While the bearings are being polished by the polishing material in cavity 21, door 23 keeps opening 22 closed.
[0047] Reference Figure 2 The baffle 4 includes a shaft 41 and a plate 42. One end of the shaft 41 is fixedly connected to the second driving member 5, and the other end of the shaft 41 passes through the roller 2 and enters the cavity 21, and the other end of the shaft 41 is rotatably connected to the roller 2; the plate 42 is located in the cavity 21, and the plate 42 is fixedly connected to the shaft 41 and is located on one side of the radial direction of the shaft 41.
[0048] Reference Figure 2 and Figure 3The baffle 4 is an arc-shaped plate, and one side of the baffle 4 has an arc-shaped surface 421. After the bearing rotates with the drum 2 in the cavity 21, the bearing contacts the arc-shaped surface 421. At this time, the bearing continues to move in the same direction as the rotation direction of the drum 2. The bearing will flip over under the blocking and guiding effect of the arc-shaped surface 421, and then the bearing will move back to the bottom of the cavity 21 under the action of its own gravity.
[0049] The polishing device further includes an anti-skid pad 6, which is installed in the cavity 21. The anti-skid pad 6 is fixedly connected to the peripheral wall of the cavity 21, and after the anti-skid pad 6 is installed, it covers the peripheral wall of the cavity 21. In this embodiment, the anti-skid pad 6 is preferably a wear-resistant rubber product.
[0050] The surface of the anti-slip pad 6 facing away from the roller 2 has a plurality of elastic columns 61. These columns 61 are arranged in rows with equal spacing between them. The columns 61 in a row are arranged parallel to the rotational axis of the roller 2, and the spacing between adjacent columns 61 in the same row is equal. The columns 61 in adjacent rows are staggered. The spacing between adjacent columns 61 is equal and no less than the particle size of the polishing material.
[0051] When the bearing sinks to the bottom in cavity 21, several elastic columns 61 support the bearing, creating space beneath the bearing for the polishing material to pass through, ensuring that the bottom surface of the bearing is fully polished by the polishing material. When the roller 2 rotates, driving the bearing, the friction between the bearing and the elastic columns 61 is high, reducing the probability of the bearing slipping after contact with the baffle 4 and improving the reliability of the bearing flipping after contact with the baffle 4.
[0052] During the rotation of the baffle 4, a gap exists between the end of the plate 42 away from the shaft 41 and the elastic column 61. The plate 42 is provided with a plurality of through holes 422 for the polishing material to pass through. Therefore, the plate 42 only intercepts the bearing, and the polishing material can pass through the interception of the plate 42 when it moves with the rotation of the drum 2.
[0053] The position of the baffle 4 is different when the polishing equipment is in different use states:
[0054] Reference Figure 4When the polishing equipment is loaded, that is, when the bearing to be polished and the polishing material need to be put into the cavity 21, the first driving member 3 is controlled to drive the roller 2 to rotate so that the opening 22 is located at the top of the roller 2, and at the same time, the second driving member 5 is controlled to drive the baffle 4 to rotate so that the plate body 42 is located below the opening 22. At this time, after the bearing and the polishing material are put through the opening 22, the bearing can fall onto the plate body 42, effectively avoiding the bearing falling directly to the bottom of the roller 2 and causing a strong collision; the polishing material will also fall to the bottom of the cavity 21 under the buffering effect of the plate body 42, reducing the damage caused by the collision between the polishing material and the anti-slip pad 6 after it is put into.
[0055] Reference Figure 3 When the polishing equipment is about to polish the bearing, it first controls the second driving member 5 to drive the baffle 4 to rotate, so that the bearing supported on the baffle 4 drops to the bottom of the cavity 21, and finally makes the end of the plate body 42 away from the shaft body 41 stop on the side of the bottom of the cavity 21 along the rotation direction of the drum 2. At this time, the position of the plate body 42 in the cavity 21 is the position where the bearing will flip subsequently. The baffle 4 can be slightly rotated to adjust the position where the bearing will flip.
[0056] Reference Figure 5 When the polishing equipment is unloading, that is, after the bearing polishing is completed, the first driving member 3 is controlled to drive the roller 2 to rotate so that the opening 22 is located at the bottom of the roller 2, and at the same time, the second driving member 5 is controlled to drive the baffle 4 to rotate in the direction opposite to the rotation direction of the roller 2 and then keep it horizontal. During the rotation of the baffle 4, the bearing located at the bottom of the cavity 21 can be picked up, and finally the bearing stays on the plate body 42, and the polishing material can be unloaded from the opening 22 first; after the polishing material is unloaded, the second driving member 5 is controlled to rotate in the same direction as the rotation direction of the roller 2, so that the bearing can be unloaded from the opening 22, completing the separation of the bearing and the polishing material.
[0057] The implementation principle of a high-gloss bearing polishing device in the embodiment of the present application is as follows:
[0058] The bearing to be polished and the polishing material are put into the cavity 21, and after the second driving member 5 is controlled to drive the baffle 4 to rotate to the appropriate position, the first driving member 3 is controlled to drive the roller 2 to rotate. During the rotation of the roller 2, the bearing and the polishing material will be driven to move. During the movement of the polishing material, the surface of the bearing can be polished. After the bearing moves to contact the baffle 4, it will flip over, so that the surface of the bearing can be evenly polished, thereby improving the polishing efficiency of the polishing equipment on the bearing.
[0059] The embodiments of the present application also disclose a polishing process for a high-gloss bearing.
[0060] A polishing process for a high-gloss bearing uses the above-mentioned polishing equipment to polish the bearing. The specific steps are as follows:
[0061] S1. Control the first driving member 3 to drive the drum 2 to rotate until the opening 22 is located at the top of the drum 2. Simultaneously, control the second driving member 5 to drive the baffle 4 to rotate until the plate 42 is located below the opening 22. Then, open the door cover 23, drop the bearing to be polished and the polishing material into the opening 22, and let the bearing to be polished fall onto the plate 42. Then, close the door cover 23.
[0062] S2. Control the second driving member 5 to drive the baffle 4 to rotate, so that the bearing on the plate 42 falls to the bottom of the cavity 21. At this time, the plate 42 is located on the side of the bearing along the rotation direction of the drum 2. Then control the first driving member 3 to drive the drum 2 to rotate. The rotation of the drum 2 drives the bearing and the polishing material to move. The polishing material polishes the surface of the bearing during the movement. The bearing moves and contacts the plate 42 and then flips, so that the surface of the bearing is evenly polished by the polishing material.
[0063] S3. After the bearing polishing process is completed, the first driving member 3 is controlled to drive the drum 2 to rotate until the opening 22 is located at the bottom of the drum 2. At the same time, the second driving member 5 is controlled to drive the baffle 4 to rotate. The plate body 42 picks up the polished bearing and separates it from the polishing material. Then the door cover 23 is opened to discharge the polishing material from the opening 22. After the polishing material is discharged, the second driving member 5 is controlled to drive the baffle 4 to rotate to discharge the polished bearing from the opening 22.
[0064] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
