Description

Technical Field

[0001] The invention relates to the technical field of bearing production polishing, and in particular to a bearing ring polishing device used for bearing production. Background Art

[0002] The inner ring of the bearing is a component in the bearing. The inner ring of the bearing usually fits tightly with the shaft and rotates with the shaft; the outer wall of the inner ring of the bearing is in direct contact with the rolling element. In order to reduce the friction between the outer wall of the inner ring of the bearing and the rolling element, the outer wall of the inner ring of the bearing needs to be polished to reduce the surface roughness of the outer wall of the inner ring of the bearing, thereby reducing the friction between the outer wall of the inner ring of the bearing and the rolling element.

[0003] At present, there are many types of bearings, especially ball bearings. There is a ball track groove on the inner wall of the outer ring of the ball bearing. If the friction coefficient of the track groove is too large, it will affect the rolling of the ball inside, and eventually affect the rotational lubrication of the bearing. The existing technology generally uses machine tool clamping and polishing to polish and grind this position, but bearings are generally produced and processed in batches. If only a single clamping polishing is used;

[0004] First, it will affect the production and processing efficiency of the entire bearing, because the clamping before polishing and the material removal after polishing will delay the processing time for a long time, which will eventually affect the production efficiency of the bearing;

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 8 A bearing ring polishing device for bearing production includes a frame 1, a rotating seat 2, a feed assembly 3 mounted on the frame 1, and the rotating seat 2 is connected to a self-circulating polishing assembly 5. A discharge rack 4 is fixedly connected to the frame 1, and the discharge rack 4 is tilted. The polished bearing ring is squeezed and ejected, so that it is discharged from the position of the discharge rack 4.

[0035] In this embodiment, the feed assembly 3 is used to automatically feed the unpolished bearing ring;

[0036] See also Figure 3-Figure 5The feed assembly 3 includes a material box 301, and a plurality of unpolished bearing rings are placed inside the material box 301. A pull plate 302 is slidably connected to the material box 301, and a pressure plate 303 is slidably connected inside the material box 301. A feed spring 305 is connected to one side of the pressure plate 303, and one end of the feed spring 305 is connected to the material box 301. The bearing rings are placed in batches on the material box 301, and the feed spring 305 squeezes the pressure plate 303 to provide a backward squeezing force for the bearing rings, and then the pull plate 302 is pulled to close it to prevent the bearing rings from popping out. The whole principle is similar to the principle of "automatic clamping of bullets". When the internal bearing rings of the material box 301 are consumed, the operator only needs to replenish them.

[0037] For further information, see Figure 4 and Figure 5 , a plurality of V-shaped grooves are provided on the rotating seat 2, an arc strip 304 is connected to the frame 1, a material block 306 is fixedly connected to the rotating seat 2, and the material box 301 is connected to the frame 1 through a connecting piece. A clearance groove 3011 and a material discharge groove 3012 are provided at the bottom of the material box 301, an extrusion groove 3013 is provided on the arc strip 304, and an inclined surface is provided on the arc strip 304. Through the material block 306 provided on the rotating seat 2, the material block 306 will enter the material box 301 from the position of the clearance groove 3011 during the rotation process, and then the bearing ring at the bottom will be moved out from the position of the material discharge groove 3012, and then the bearing ring will contact the inclined surface of the arc strip 304. During the rotation process, the bearing ring will exert downward pressure after contacting the inclined surface, so that it can enter the inside of the V-shaped groove and be flush with the rotating seat 2, and finally the bearing ring will be stuck in the position of the V-shaped groove to fix its relative position.

[0038] Furthermore, the self-circulating polishing assembly 5 is used for self-rotating circulating polishing of the inner ring of the bearing; the self-circulating polishing assembly 5 includes a rotating device, a polishing device and a discharging device.

[0039] See also Figure 6 The rotating device includes a driving motor 201, the output end of the driving motor 201 is connected to the rotating seat 2, the rotating seat 2 is rotatably connected with a driving wheel 505, one side of the driving wheel 505 is fixedly connected with a driving gear 504, the driving gear 504 is meshed with a toothed disc 506, and the toothed disc 506 is fixed on the frame 1. The slow rotation of the driving motor 201 will drive the rotating seat 2 to rotate, and at this time, the bearing ring at the bottom will enter the position of the first V-groove with the rotation of the rotating seat 2. The driving gear 504 is meshed and rotated with the toothed disc 506, so when the toothed disc 506 is fixed, the driving gear 504 will form a self-rotation to provide power for the subsequent polishing rotation. While the rotating seat 2 rotates, the self-feeding polishing of the bearing ring is continuously realized.

[0040] Also, see Figure 6The polishing device includes a sliding rod 501, which is slidably connected to the rotating seat 2, and a compression spring 502 is sleeved on the sliding rod 501, one end of which is connected to the rotating seat 2, and a transmission wheel 503 is rotatably connected to the sliding rod 501, and a polishing roller 508 is connected to the transmission wheel 503. There are multiple polishing devices, and the multiple polishing devices are distributed in a central circular array of the rotating seat 2, and the multiple transmission wheels 503 are connected to the driving wheel 505 through toothed belt transmission. The driving wheel 505 will drive the overall toothed belt to rotate, and the rotation of the toothed belt will drive the multiple transmission wheels 503 to rotate, so the transmission wheel 503 will drive the polishing roller 508 to rotate, and the rotation of the polishing roller 508 will polish the inner wall of the bearing ring while rotating, and the bearing ring will also rotate following the extrusion state, so the rotation between the two will achieve the overall polishing of the inner ring.

[0041] In addition, see Figure 6 The rotating seat 2 is connected to a plurality of movable wheels 516 through a slider, and a buffer spring 511 is connected to the slider, and the plurality of movable wheels 516 are all connected to the toothed belt transmission. The movable wheels 516 are provided as a whole so that when a certain polishing roller 508 is displaced, the entire toothed belt will be stretched by the plurality of buffer springs 511, so that the entire toothed belt is always in a taut transmission state, so that the transmission polishing will not fail.

[0042] It is worth noting that see Figure 7 and Figure 8 The discharging device includes a fixed frame 509, which is fixed on the frame body 1, and a cam 507 is fixedly connected to the fixed frame 509. One end of the sliding pull rod 501 is slidably connected to the surface of the cam 507, and the cam 507 is rotatably connected to the rotating seat 2. A support rod 515 is fixedly connected to the fixed frame 509, and a sliding frame 512 is slidably connected to the support rod 515. Two hammers 513 are connected to the sliding frame 512. A plurality of extrusion plates 510 are connected to the rotating seat 2, and the side surfaces of the extrusion plates 510 are provided with inclined surfaces. A return spring 514 is sleeved on the support rod 515. The rotation of the rotating seat 2 will drive the synchronous rotation of the extrusion plate 510, and then the inclined surface of the extrusion plate 510 will form an inclined surface extrusion state with the hammer 513, thereby driving the entire sliding frame 512 to slide on the support rod 515 and squeeze the reset spring 514. With continuous rotation, when the extrusion plate 510 is separated from the hammer 513, the sliding frame 512 will be affected by the elastic force of the reset spring 514 and extend, thereby squeezing and ejecting the polished bearing ring in the V-groove, so that it is discharged from the position of the discharge rack 4.

[0043] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0044] The working principle is that the operator first needs to place the bearing rings that need to be polished in batches on the material box 301, and use the feed spring 305 to squeeze the pressure plate 303 to provide a backward squeezing force for the bearing ring, and then pull the pull plate 302 to close it to prevent the bearing ring from popping out. Then, as the driving motor 201 rotates slowly, it will drive the rotation of the rotating seat 2. At this time, the bearing ring at the bottom will be brought out from the bottom of the material box 301 with the rotation of the rotating seat 2. Because the rotating seat 2 is provided with a material block 306, the material block 306 will enter the material box 301 from the position of the give way groove 3011 during the rotation process, and then the bearing ring brought out from the position of the discharge groove 3012, and then the bearing ring will contact the inclined surface of the arc strip 304. During the rotation process, the bearing ring will apply downward pressure after contacting the inclined surface, so that it can enter the inside of the V-shaped groove and be flush with the rotating seat 2. Then, the bottom end of the sliding rod 501 will be separated from the convex point position of the cam 507. Therefore, as the rotating seat 2 rotates, the contraction of the extrusion spring 502 will drive the transmission wheel 503 connected thereto to contract, so that the polishing roller 508 is pressed against the inner wall of the bearing ring and realizes a pressing contact therewith, and then as the rotating seat 2 rotates, the driving wheel 505 and the driving gear 504 are driven to rotate. At this time, the driving gear 504 is meshed and rotated with the toothed disk 506, so when the toothed disk 506 is fixed, the driving gear 504 will form self-rotation, thereby driving the rotation of the driving wheel 505, and the driving wheel 505 will drive the entire toothed belt to rotate, and the rotation of the toothed belt will drive multiple transmission wheels 503 to rotate, so the transmission wheel 503 will drive the polishing roller 508 to rotate, and the rotation of the polishing roller 508 will rotate and polish the inner wall of the bearing ring, and the bearing ring will also rotate following the extrusion state, so the rotation between the two will realize the overall polishing of the inner ring, and as the rotating seat 2 rotates, it will gradually rotate to the position of the discharging device. During the rotation of the rotating seat 2, the extrusion plate 510 will be driven to rotate synchronously, and then the inclined surface of the extrusion plate 510 will form an inclined surface extrusion state with the hammer 513, thereby driving the entire sliding frame 512 to slide on the support rod 515 and squeeze the return spring 514. With continuous rotation, when the extrusion plate 510 is separated from the hammer 513, the sliding frame 512 will be extended by the elastic force of the return spring 514, and then the polished bearing ring in the V-groove will be squeezed and ejected, so that it is discharged from the position of the discharge rack 4. Considering that the ball on the polishing roller 508 is stuck in the ball groove on the inner wall of the bearing ring, a cam 507 is set. When the rotating seat 2 rotates to the position of the discharge device, the bottom of the sliding rod 501 will be at the convex point position of the rotating cam 507, so at this time the sliding rod 501 will be ejected, so that the polishing roller 508 is separated from the inner ring of the bearing, which is convenient for the subsequent automatic discharge and will not get stuck.

[0045] In summary, the device utilizes the self-rotation method to realize the automatic clamping of the bearing ring, and utilizes the self-rotation planetary rotation to automatically polish the inner wall of the bearing ring, which can not only improve the overall polishing efficiency, but also save the operator's redundant operations, making the overall polishing simpler and more convenient, reducing the operator's processing requirements, and reducing the overall labor intensity of the operator. In addition, the V-groove clip-on spring is tightened to lock in place, which can minimize deformation during the grinding process, so that the overall bearing ring will not undergo a large amount of deformation and a large amount of dimensional error during the polishing process.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
