Description

Technical Field

[0001] The invention relates to the field of bearing processing, and in particular to a bearing outer ring polishing device. Background Art

[0002] Bearings are important mechanical parts that support mechanical rotating bodies, reduce the friction coefficient during movement, and ensure their rotation accuracy. To ensure the accuracy and performance of bearings, the raceways of bearings need to be super-finished before leaving the factory to meet the requirements for the surface roughness of the bearing raceways.

[0003] The Chinese invention patent with publication number CN113524004B is a surface polishing device for processing bearing outer rings and its use method. The technical problems to be solved by the invention are unstable fixing and easy to fall off, inability to adjust and limit the outer rings of various bearings of different models, and low processing efficiency of the processing device. In order to solve the above technical problems, the invention provides a surface polishing device for processing bearing outer rings. The invention consists of a mechanical base, a fixing mechanism and a polishing mechanism. The invention can quickly fix the outer ring of the bearing through the cooperation of the first electric push rod and the movable sleeve. Through the setting of the positioning block, the outer rings of the bearings will not collide with each other and cause damage. The inner side has an elastic rubber pad, which makes it easy to deform when clamping the outer ring of the bearing, thereby making the fixing effect better and avoiding damage to the inner side of the outer ring of the bearing, making it more convenient and better quality when polishing the outer ring of the bearing, and polishing the surfaces of the outer rings of bearings of different models. The structure is flexible and widely applicable.

[0004] Although the above patent can polish the outer ring surface of bearings of different models, the factory thickness of each bearing ring is different. In order to ensure that the thickness error of the bearing ring after processing is reduced to the minimum, the time required for processing a bearing ring is different.

[0005] When the equipment in this patent is processed, after polishing of one of the bearing rings is completed, it is necessary to stop the machine and disassemble the bearing ring before continuing to polish other bearing rings. The operation procedures are cumbersome and it is impossible to realize simultaneous processing of multiple bearings. In addition, without affecting the processing of other unpolished bearing rings, the bearing ring that has been polished is cut, which affects the processing efficiency and cycle.

[0006] Therefore, it is necessary to invent a bearing outer ring polishing device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] The present invention provides Figure 1-16A bearing outer ring polishing device shown in the figure includes a base 1 and a bearing ring 13. A connecting groove is provided on the side wall of the base 1, which can realize continuous installation and connection of multiple bases 1 to achieve combined connection between multiple groups of equipment. A back plate 2 is provided on the top of the base 1, and a plurality of lifting platforms 8 are hingedly provided on the back plate 2. A plurality of feeding and discharging components 14 are slidably connected to the plurality of lifting platforms 8. A plurality of lifting components 11 arranged in an array are hingedly provided between the base 1 and the lifting platform 8. A plurality of connecting components 10 are provided on the top of the lifting platform 8. A plurality of clamping mechanisms 4 capable of positioning and clamping the bearing ring 13 are provided on the connecting component 10. A polishing roller 5 is provided on the top of the clamping mechanism 4. The polishing roller 5 is arranged in a close fit with the bearing ring 13, and a clamping mechanism 3 is provided at both ends of the polishing roller 5.

[0048] When the above structure is specifically operated, the bearing ring 13 can be placed in the feed-in and feed-out assembly 14, and the lifting platform 8 can be pushed by the lifting assembly 11 to lift the bearing ring 13 located in the feed-in and feed-out assembly 14 to the adjacent clamping mechanism 4, and the polishing roller 5 can be connected to the driving device. Furthermore, a toothed disc is provided at the power input end of the polishing roller 5, and an elastic lifting device is provided at the bottom of the driving device, which can elastically push to keep the toothed disc at the output end always meshing and rotating with the toothed disc at the input end of the polishing roller 5. Similarly, the driving device can be pushed by an electric telescopic device to be lifted and lowered to keep it consistent with the polishing roller 5 during the height adjustment process, and there is no restriction on the driving means of the polishing roller 5.

[0049] The bearing ring 13 is polished by rotating the polishing roller 5, and one side of the lifting platform 8 is lifted by the lifting assembly 11, so that the debris during the polishing process falls into the chute 6 for centralized collection and discharge, avoiding the situation where the debris accumulates and is difficult to clean.

[0050] like Figure 1-Figure 2As shown, the material inlet and outlet assembly 14 includes a fixed slide 141, a guide slide 143 and an electric push rod 142. The fixed slide 141 is arranged on the top of the lifting platform 8. There are two guide slides 143, and the two guide slides 143 are arranged in a mirror-symmetrical manner. A plurality of slide grooves 6 are opened on the top of the lifting platform 8. Sliding blocks 144 are slidably connected in the plurality of slide grooves 6. A cross bar is connected to the top of the sliding block 144. The top of the cross bar is connected to the bottom of the two guide slides 143. One end of the electric push rod 142 is connected to the inner side wall of the slide groove 6, and the other end of the electric push rod 142 is connected to the sliding block 144. First, the electric push rod 142 is driven, and the power output of the electric push rod 142 pushes the sliding block 144 to move in the slide groove 6. The sliding block 144 drives the guide slide 143 to move and adjust the position. First, the guide at the head end When the slide 143 moves to correspond to the position of the fixed slide 141, the bearing ring 13 can be transported to the fixed slide 141 through the guide slide 143 at the head end by an external conveying device, and the lifting assembly 11 is used to drive the lifting platform 8 to lift and install the bearing ring 13 into the clamping mechanism 4. Secondly, when the processed bearing ring 13 needs to be discharged, the guide slide 143 at the tail end is driven to move and dock with the fixed slide 141 in the same way. At this time, the bearing ring 13 is separated from the clamping mechanism 4 after processing and falls into the fixed slide 141. The lifting assembly 11 is used to drive one side of the lifting platform 8 to rise and fall, so that the bearing ring 13 passes through the fixed slide 141 and enters the guide slide 143 at the tail end, and is guided and discharged to the designated processing line by the guide slide 143, thereby fully realizing automation and avoiding manual intervention.

[0051] like Figure 3 As shown, the lifting assembly 11 includes a hydraulic telescopic rod 111 and a material unloading platform 112. The bottom end of the hydraulic telescopic rod 111 is hinged on the base 1, and the top end of the hydraulic telescopic rod 111 is hinged on the bottom of the lifting platform 8. The material unloading platform 112 is arranged on the top of the base 1, and the material unloading platform 112 is connected to the side wall of the back plate 2. A side baffle 113 is arranged on the top of the material unloading platform 112. A material unloading port 114 corresponding to the position of the material unloading platform 112 is opened on the lifting platform 8. When the hydraulic telescopic rod 111 is extended, it pushes one side of the lifting platform 8 to lift up, and the lifting platform 8 is lifted. The top is formed in an inclined shape, and the debris accumulated on the top of the lifting platform 8 can slide into the discharge port 114 along the inclined setting of the top of the lifting platform 8, and then fall to the top of the discharge platform 112 through the discharge port 114. With the inclined setting of the top of the discharge platform 112, the debris slides out, and the debris can be conveniently collected by placing a collection bucket at the low point of the inclination of the discharge platform 112. The side baffle 113 acts as a material barrier in this process to prevent the debris from sliding from the side wall of the discharge platform 112, causing difficulty in cleaning.

[0052] like Figure 4 , Figure 5 , Figure 7 , Fig.14 , Fig.15 and Fig.16 As shown, the connecting assembly 10 includes a side plate 101 and a support rod 102, and the side plate 101 and the support rod 102 are both arranged on the side wall of the back plate 2. A transverse groove 7 is provided on the side wall of the side plate 101, and the clamping mechanism 4 is slidably connected in the transverse groove 7. A control button 103 is provided on the side wall of the side plate 101, and the control button 103 is electrically connected to the hydraulic telescopic rod 111. The clamping mechanism 3 includes a female seat 31 and a male seat 32. The female seat 31 is arranged at the head end of the polishing roller 5, and the male seat 32 is arranged at the tail end of the polishing roller 5. A card slot cooperating with the male seat 32 is provided on the female seat 31, and a card plate cooperating with the card slot is provided on the male seat 32. Positioning holes are provided on the card plate and the female seat 31, and the outer wall of the female seat 31 and the male seat 32 A positioning ring 33 is provided on each of the supporting rods 102, and a U-shaped groove which cooperates with the positioning ring 33 is provided on the supporting rod 102. Specifically, the supporting rod 102 supports multiple polishing rollers 5. A transverse groove 7 is provided on the side plate 101 to facilitate the first clamping seat 41 to slide and move in the transverse groove 7 when the clamping mechanism 4 is extended and retracted, thereby achieving stable fixation of bearing rings 13 of different sizes. Two control buttons 103 are provided and are electrically connected to the hydraulic telescopic rod 111. During the process, after the control button 103 at the head end is activated, the hydraulic telescopic rod 111 is energized to extend, and after the control button 103 at the tail end is activated, the lifting assembly 11 is energized to retract, thereby facilitating the lifting platform 8. The angle can be adjusted to facilitate loading and unloading. When connecting and disassembling the polishing roller 5, the bar bolt for fixing is manually inserted into the two adjacent positioning holes and placed in the U-shaped groove to realize the connection and installation of the two polishing rollers 5; further, the top of the support rod 102 can be provided with a fixing cover matching its size and embedded and installed with its top, and fixed to the top of the support rod 102 by bolts. A rectangular groove is provided on the support rod 102, and a slidable and retractable positioning push plate 104 is provided in the rectangular groove. The rotation of the positioning push plate 104 is connected to a plurality of sliding rollers arranged in an array, and the sliding rollers are jointly fitted with the outer side walls of the female seat 31 and the male seat 32. An elastic telescopic cylinder 105 is provided at the tail end of the positioning push plate 104 A return spring is arranged inside the elastic telescopic cylinder 105, and one end of the elastic telescopic cylinder 105 is connected to the side wall of the rectangular groove. When the clamping mechanism 3 is rotated and connected in the U-shaped groove, the elastic force of the return spring pushes the bottom arc setting of the elastic telescopic cylinder 105 to fit with it. The main function is to prevent the bearing ring 13 from fitting too loosely with the polishing roller 5, and to push the polishing roller 5 to fit with the bearing ring 13. After the bearing ring 13 and the polishing roller 5 fit, when the polishing roller 5 pushes the female seat 31 and the male seat 32 to move toward the top, the positioning push plate 104 has a better telescopic effect, which prevents the height of the polishing roller 5 from being unchanged, and the bearing ring 13 from getting stuck with the polishing roller 5 when it moves toward the top. Figure 4 , Figure 5, Figure 6 and Figure 8 As shown, the clamping mechanism 4 includes a first clamping seat 41, a second clamping seat 42, an electric telescopic rod 47 and a limit rod 48. Connecting rods are provided on both sides of the first clamping seat 41. The two connecting rods are respectively slidably connected in adjacent transverse grooves 7. Fixed rods are provided on both sides of the second clamping seat 42. One end of the two fixed rods is connected to the side wall of the adjacent side plate 101. Adjustment components 43 are provided in the first clamping seat 41 and the second clamping seat 42. Side mounting plates 44 are provided on the side walls of the two adjustment components 43. The two adjacent side mounting plates 44 are slidably connected by the limit rod 48 and the electric telescopic rod 47. The electric telescopic rod 47 can control the clamping, fixing and disassembly of the bearing ring 13 by telescoping. The limit rod 48 plays a role in limiting the movement. When the electric telescopic rod 47 contracts, it pulls the head end adjustment component 43 to move and approaches the tail end adjustment component 43. At this time, the distance between the two adjustment components 43 is shortened. When the bearing ring 13 is sent between the two adjustment components 43 through the fixed slide 141, the two telescopic support plates 433 in the adjustment component 43 are pushed to contract. When one side of the bearing ring 13 moves past the fixed position of the telescopic support plate 433, the elastic force of the spring pushes the telescopic support plate 433 to pop out, and cooperates with the reduction motor 45 to drive the lifting screw slide to move to the top, thereby making the bonding roller 432 fit with the inner wall of the bearing ring 13. While the bonding roller 432 fits with the inner wall of the bearing ring 13, the bearing ring 13 can roll on the bonding roller 432 to facilitate polishing.

[0053] The adjusting components 43 are each provided with a reduction motor 45, the power output shaft of the reduction motor 45 is connected with a rotating rod 46, the adjusting components 43 are provided with a vertical plate 12, the rotating rod 46 is rotatably connected to the two vertical plates 12, the rotating rod 46 is transmission-connected to the adjusting components 43, and the reduction motor 45 plays a driving function, driving the adjustment lifting screw slide to perform lifting and lowering adjustment in the adjusting seat 431, thereby realizing the clamping and adjusting function of the bearing ring 13.

[0054] The adjustment components 43 are all provided with glass observation windows 9, so that personnel can observe the internal adjustment distance size through the glass observation window 9 during adjustment, and can also help personnel understand the stability of the bearing ring 13 after clamping in the current state.

[0055] The adjusting assembly 43 comprises an adjusting seat 431 and a telescopic support plate 433. The adjusting seat 431 is connected to the side mounting plate 44. A sliding cavity is provided on the adjusting seat 431. A lifting screw slide is provided in the sliding cavity. The lifting screw slide is transmission-connected to the rotating rod 46. Two blind holes are provided on the side wall of the lifting screw slide. A first square slider and a second square slider are provided in the blind holes. One side of the first square slider and the second square slider are connected to the inner wall of the blind hole through a spring. The other side of the first square slider is rotationally connected to two laminating rollers 432. The other side of the second square slider is connected to the telescopic support plate 433. The other end of the laminating roller 432 is rotationally connected to the side wall of the telescopic support plate 433. A driving roller 436 is rotationally provided on the adjusting seat 431. The driving roller 436 is connected to the bearing ring 13 During the polishing process, in order to avoid a gap between the driving roller 436 and the bearing ring 13, the reduction motor 45 intermittently drives the lifting screw slide to lift, so as to ensure that the bearing ring 13 can continuously keep in contact with the driving roller 436 during the polishing process. A first precision micro motor 437 capable of driving the driving roller 436 to rotate is provided in the adjustment seat 431. This arrangement can facilitate the fixing and unloading of the bearing ring 13. When unloading, the lifting screw slide is driven down by the power output of the reduction motor 45. When the inclined setting of the bottom of the telescopic support plate 433 is in contact with the inclined setting of the bottom of the sliding cavity, the telescopic support plate 433 drives the fitting roller 432 to shrink into the sliding cavity. If the top wall of the bearing ring 13 is not supported, it will fall off from the adjustment component 43, thereby realizing automatic unloading.

[0056] like Figure 6 As shown, a driving roller 436 is rotatably provided on the adjustment seat 431, and the driving roller 436 is in contact with the bearing ring 13. A first precision micro motor 437 capable of driving the driving roller 436 to rotate is provided in the adjustment seat 431. The driving roller 436 rotates to drive the bearing ring 13 and the polishing roller 5 to rotate in the opposite direction, thereby improving the polishing efficiency.
