Description

Technical Field

[0001] The invention relates to the technical field of bearing grinding, in particular to an outer diameter grinding device for bearing manufacturing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The working principle of bearings is to replace sliding friction with rolling friction to reduce the friction loss between mechanical parts. Bearings are mainly composed of four parts: inner ring, outer ring, rolling element, and cage. In the manufacturing process of bearings, these four parts are generally manufactured in batches and then assembled. When manufacturing the outer ring of the bearing, the outer diameter of the outer ring needs to be polished to ensure that the outer surface of the bearing meets the required dimensional accuracy, surface roughness and geometric shape requirements. In this process, a bearing outer diameter polishing device is needed. The traditional bearing outer diameter polishing device is mainly used to convey the bearing. During the conveying process, the grinding discs arranged on both sides of the conveying path are used to polish both sides of the bearing at the same time, thereby forming an assembly line polishing work and improving the grinding efficiency of the bearing. However, the traditional grinding machine is small in size, and the bearing passes through the grinding wheel in a straight line. When the grinding wheel is grinding, it is easy to cause the arrangement of multiple bearings to be disordered, which not only leads to a shorter grinding time for the bearings, but also affects the grinding efficiency of the bearings and has a certain impact on the blanking of the bearings. Therefore, we propose an outer diameter grinding device for bearing manufacturing. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

At this time, the bearings will enter the slots in turn, and with the thrust generated by the gravity when the grinding disc rotates, the bearings will be stuck in the slots. At this time, when the grinding disc is grinding the bearings, the grinding work of the bearings can be completed in the process of conveying the bearings through the rotating plate. At the same time, the bearing's travel route can be changed by the rotating plate, so that the grinding time of the bearings is longer.

When the buffer plate moves, it drives the sealing plate to move, so that the limit opening is aligned with the drainage hole, so that the water in the water inlet joint is discharged along the drainage hole to lubricate the inner walls on both sides of the guide hopper. At the same time, the force generated by the outflowing water flow can be used to make the bearing in the guide hopper enter the unloading rack faster and more smoothly. In this process, the bearing is cooled down, which effectively improves the auxiliary function of the device for bearing unloading; 3. In the present invention, when the bearing enters the unloading rack, the rebound characteristic of the spring can drive the buffer plate back to its original position, and the buffer plate can be used to drive the sealing plate back to its original position. At this time, the sealing plate can be used to seal the drainage hole again, thereby avoiding the problem of water resource waste and effectively improving the environmental protection of the device.

DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-11The present invention provides a technical solution: an outer diameter grinding device for bearing manufacturing, comprising a base 1, a conveying frame 11 is fixedly connected to one side of the top of the base 1, a connecting frame 2 connected to the conveying frame 11 is fixedly connected to the top of the base 1, two conveyor belts 21 are arranged on the top of the base 1, and the two conveyor belts 21 are respectively located on both sides of the connecting frame 2, and a feeding frame 22 is fixedly connected to one end of the connecting frame 2 away from the conveying frame 11.

[0019] Furthermore, when the bearing is transported, the bearing enters the connecting frame 2 through the conveying frame 11. When passing through the connecting frame 2, the conveyor belts 21 on both sides thereof provide a thrust to the bearing on the connecting frame 2, thereby pushing the bearing on the connecting frame 2 onto the feeding frame 22, and preparing to grind the outer diameter of the bearing.

[0020] Combined with Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, a protrusion 23 is fixedly connected to the top of one end of the feed rack 22 close to the shell 3, and the top of the protrusion 23 is an arc-shaped structure. The top of the base 1 is fixedly connected to the shell 3, and the shell 3 is connected to the feed rack 22 in a butt connection. Two mounting plates 31 are fixedly connected in the shell 3, and mounting rings 32 are rotatably connected to the opposite sides of the two mounting plates 31. A grinding disc 33 of an annular structure is fixedly connected to the side of the mounting ring 32 away from the mounting plate 31 on the same side, and a gear ring 34 is fixedly connected to the inner wall of the grinding disc 33. The side of the mounting plate 31 close to the grinding disc 33 on the same side is rotatably connected to three annular evenly distributed transmission gears 35. The three The transmission gears 35 are all meshed with the gear ring 34 on the same side, and a driving gear 4 is meshed between the transmission gears 35. A rotating plate 41 is fixedly connected between the two driving gears 4. A gap is provided between the two grinding discs 33 and the rotating plate 41. A slot 42 with an inclined opening is provided on the edge of the rotating plate 41. A pulley A5 is fixedly connected to the mounting ring 32. A fixed motor 51 is fixedly connected in the outer shell 3. A shaft A52 is fixedly connected to the output end of the fixed motor 51. Two pulleys B53 are fixedly connected to the shaft A52. A transmission belt 54 is provided between the pulley B53 and the pulley A5 on the same side thereof.

[0021] Furthermore, the protrusion 23 on the feed rack 22 can provide a resistance to the bearing on the feed rack 22, and cooperate with the driving force of the transmission belt 21 to prevent the bearings from continuously entering the slots 42 of the rotating plate 41. The fixed motor 51 is started to drive the shaft A52 to rotate. During the rotation of the shaft A52, the pulley B53, the transmission belt 54 and the pulley A5 can cooperate to drive the mounting ring 32 to rotate, so that the mounting ring 32 can drive the grinding disc 33 to rotate. At this time, the rotation direction of the grinding disc 33 is counterclockwise. At this time, the grinding disc 33 will drive the gear ring 34 to rotate synchronously in the same direction. During the rotation of the gear ring 34, the transmission gear 35 and the driving gear 4 can cooperate to drive the rotating plate 41 to rotate clockwise in the opposite direction. During the rotation of the movable plate 41, the bearings will enter the slots 42 of the rotating plate 41 one by one, and as the rotating plate 41 and the grinding disc 33 rotate, the bearings will be stuck into the depth of the slots 42 due to the force generated by gravity and the friction of the reverse rotation of the grinding disc 33. At this time, both sides of the bearing can be polished by the grinding disc 33, and because the bearing moves with the rotating plate 41, the straight path of the bearing can be changed into an arc path by the rotating plate 41, thereby improving the polishing time of the bearing, and by the rotation of the rotating plate 41, the bearing can be transported during the polishing process, and due to the design of the slots 42 on the rotating plate 41, the bearings can be arranged in sequence on the rotating plate 41, thereby improving the stability of the arrangement sequence of the bearings during polishing.

[0022] Combined with Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.11As shown, a rotating motor 6 is fixedly connected to an inner wall of one side of the shell 3 through a frame, and a shaft rod B61 is fixedly connected to the output end of the rotating motor 6, and a material discharge component 62 is fixedly connected to the shaft rod B61, and the material discharge component 62 includes a mounting seat 621 and a material discharge rod 622, and a mounting seat 621 is fixedly connected to the shaft rod B61, and both ends of the mounting seat 621 are fixedly connected with a plurality of annular evenly distributed material discharge rods 622, and the material discharge rods 622 are all arc-shaped structures, and the material discharge rods 622 at both ends of the mounting seat 621 are located in the gap between the grinding disc 33 and the rotating plate 41 on the same side thereof, and a material discharge rack 7 is fixedly connected to the side of the shell 3 away from the feed rack 22, and a material guide hopper 71 is fixedly connected to the top of the material discharge rack 7 close to one end of the rotating plate 41, and the material guide hopper 71 is located Below the mounting seat 621, the inner walls on both sides of the guide hopper 71 are provided with a plurality of drainage holes 72, and sealing plates 73 are slidably connected on both sides of the guide hopper 71, and the sealing plates 73 are provided with limit openings 74 with the same number as the drainage holes 72, and a buffer plate 75 is slidably connected to the inner wall of the side of the guide hopper 71 close to the rotating plate 41, and connecting rods 76 are fixedly connected between the two ends of the buffer plate 75 and the sealing plates 73 on the same side, and a spring 77 is fixedly connected between the buffer plate 75 and the inner wall of the side of the guide hopper 71 close to the rotating plate 41, and water inlet connectors 78 are fixedly connected on both sides of the guide hopper 71, and the water inlet connectors 78 are connected to the drainage holes 72 on the same side, and a storage box 8 is fixedly connected to the side of the base 1 close to the lower material rack 7, and a screen 81 is placed in the storage box 8.

[0023] Furthermore, when grinding the bearing, start the rotating motor 6 to drive the shaft B61 to rotate. At this time, the shaft B61 can drive the mounting seat 621 and the discharge rod 622 to rotate. During the rotation of the discharge rod 622, the bearing located in the slot 42 can be pushed into the guide hopper 71 through the gap between the grinding disc 33 and the rotating plate 41. When the bearing falls into the guide hopper 71, the bearing will first contact the buffer plate 75. At this time, the impact force generated when the bearing falls will drive the buffer plate 75 to move and cause the spring 77 to contract. At this time, an external water pipe is installed on the water inlet joint 78, and the water pipe and the water pump are used to transport the water in the external water source to the water inlet joint 78. When the buffer plate 75 moves, it can use the connecting rod 76 to drive the sealing plate 73 to move. At this time, the limit on the sealing plate 73 The opening 74 will be aligned with the drainage hole 72. At this time, the water in the water inlet joint 78 will be discharged along the drainage hole 72. At this time, the discharged water is used to wet and lubricate the inner walls of the two sides of the guide hopper 71, so that the bearing can enter the unloading rack 7 more smoothly, and the polished bearing can also be cooled. At the same time, when the bearing falls into the unloading rack 7, the spring 77 begins to rebound, driving the buffer plate 75 back to its original position. At this time, the buffer plate 75 will drive the sealing plate 73 back to its original position through the connecting rod 76. At this time, the sealing plate 73 can be used to block the drainage hole 72 to avoid water waste. Finally, the bearing will roll into the storage box 8 along the unloading rack 7. At this time, the screen 81 can be used to separate the bearing and water. When the grinding work of this batch of bearings is completed, the screen 81 is taken out from the storage box 8, and the bearings can be collected in a centralized manner.

[0024] Combined with Figure 1 As shown, a load-bearing seat 9 is provided on one side of the base 1 close to the conveying frame 11, a loading port 91 is opened on the top of the load-bearing seat 9, a transmission frame 92 is installed on one side of the loading port 91 through a frame, a plurality of baffles 93 are rotatably connected to the transmission frame 92, and inclined guide plates 94 are fixedly connected to the baffles 93, a collecting box 95 is fixedly connected to the top of the load-bearing seat 9 close to the side of the base 1, and a discharge pipe 96 connected to the loading port 91 is fixedly connected to the bottom of the collecting box 95.

[0025] Furthermore, when the bearing is transported, the bearing to be polished is first placed in the loading port 91, and then the transmission frame 92 is started to drive the baffle plate 93 to rise. In this process, the baffle plate 93 located in the loading port 91 can use the guide plate 94 to lift out part of the bearing during the rising process. At this time, the bearing will roll along the guide plate 94 to its inclined end. At this time, the side of the collecting box 95 can be used to limit the bearing on the guide plate 94 to avoid the problem of the bearing slipping. When the baffle plate 93 moves to the top of the conveying frame 11, the guide plate 94 will be aligned with the conveying frame 11, and the limit on the side of the collecting box 95 for the bearing disappears. At this time, the bearing will enter the conveying frame 11 from the guide plate 94 and be transported to the subsequent machine to prepare for polishing. In the process of the bearing entering the conveying frame 11 from the guide plate 94, if it accidentally falls off, the collecting box 95 can be used to collect this part of the bearing, and finally it is discharged back into the loading port 91 through the discharge pipe 96.

[0026] Working principle: first, the bearing to be polished is placed in the loading port 91, and then the transmission frame 92 is started to drive the baffle plate 93 to rise. During this process, the baffle plate 93 located in the loading port 91 can use the guide plate 94 to lift part of the bearing during the rising process. At this time, the bearing will roll along the guide plate 94 to its inclined end. At this time, the side of the collecting box 95 can be used to limit the bearing on the guide plate 94 to avoid the problem of the bearing slipping. When the baffle plate 93 moves to the top of the conveying frame 11, the guide plate 94 will be aligned with the conveying frame 11, and the limit on the side of the collecting box 95 for the bearing disappears. At this time, the bearing will enter the conveying frame 11 from the guide plate 94 and be transported to the subsequent machine to prepare for polishing. In the process of the bearing entering the conveying frame 11 from the guide plate 94, if it accidentally falls off, the collecting box 95 can be used to collect this part of the bearing, and finally it is discharged back into the loading port 91 through the discharge pipe 96. After the bearing enters the connecting frame 2 through the conveying frame 11, the conveyor belts 21 on both sides of the connecting frame 2 provide a thrust to the bearing on the connecting frame 2, thereby pushing the bearing on the connecting frame 2 to the feeding frame 22, and preparing to grind the outer diameter of the bearing; The fixed motor 51 is started to drive the shaft A52 to rotate. During the rotation of the shaft A52, the mounting ring 32 can be driven to rotate by the pulley B53, the transmission belt 54 and the pulley A5, so that the grinding disc 33 can be driven to rotate by the mounting ring 32. At this time, the grinding disc 33 rotates counterclockwise. At this time, the grinding disc 33 will drive the gear ring 34 to rotate synchronously in the same direction. During the rotation of the gear ring 34, the transmission gear 35 and the driving gear 4 can be used to drive the rotating plate 41 to rotate clockwise in the opposite direction. During the rotation of the rotating plate 41, the bearings will enter the slots 42 of the rotating plate 41 one by one, and as the rotating plate 41 and the grinding disc 33 rotate, the bearings will be stuck in the depth of the slots 42 due to the force generated by the gravity and the reverse rotation friction of the grinding disc 33. At this time, the grinding disc 33 can grind both sides of the bearing. At this time, during the grinding of the bearing, the conveying work will be completed by the rotation effect of the rotating plate 41. Then, the rotating motor 6 is started to drive the shaft B61 to rotate. At this time, the shaft B61 can drive the mounting seat 621 and the discharge rod 622 to rotate. During the rotation of the discharge rod 622, the bearing located in the slot 42 can be pushed into the guide hopper 71 through the gap between the grinding disc 33 and the rotating plate 41. When the bearing falls into the guide hopper 71, the bearing will first contact the buffer plate 75. At this time, the impact force generated when the bearing falls will drive the buffer plate 75 to move and cause the spring 77 to contract. At this time, an external water pipe is installed on the water inlet joint 78, and the water pipe and the water pump are used to transport the water in the external water source to the water inlet joint 78. When the buffer plate 75 moves, it can use the connecting rod 76 to drive the sealing plate 73 to move. At this time, the limit opening 74 on the sealing plate 73 will contact the drainage The holes 72 are aligned, and the water in the water inlet joint 78 will be discharged along the drainage hole 72. At this time, the discharged water is used to wet and lubricate the inner walls of the guide hopper 71 on both sides, so that the bearing can enter the unloading rack 7 more smoothly, and the polished bearing can also be cooled. At the same time, when the bearing falls into the unloading rack 7, the spring 77 begins to rebound, driving the buffer plate 75 back to its original position. At this time, the buffer plate 75 will drive the sealing plate 73 back to its original position through the connecting rod 76. At this time, the sealing plate 73 can be used to block the drainage hole 72 to avoid the problem of water waste. Finally, the bearing will roll into the storage box 8 along the unloading rack 7. At this time, the screen 81 can be used to separate the bearing and water. When the grinding work of this batch of bearings is completed, the screen 81 is taken out from the storage box 8, and the bearings can be collected in a centralized manner.
