Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a surface grinding device with the function of synchronously grinding inner and outer rings. 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. In the process of processing bearings, the bearing rings need to be polished. During the polishing process, the inner and outer rings of the bearing rings need to be polished separately.

[0003] In the process of grinding the bearing ring, it is usually necessary to clamp the outer ring or the inner ring of the bearing ring in turn by using tools. Since the clamping tool will block the inner ring or the outer ring of the bearing ring, after the grinding of the outer ring or the inner ring is completed, the bearing ring needs to be removed again and re-clamped for grinding, which reduces the grinding efficiency and makes the entire grinding process inefficient and time-consuming. Utility Model Content

[0004] The purpose of the utility model is to provide a surface grinding device with the function of synchronously grinding inner and outer rings, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides a surface grinding device with the function of synchronous grinding of inner and outer rings, including a bearing ring, a grinding and fixing assembly is arranged on the periphery of the bearing ring, the grinding and fixing assembly includes a plurality of grinding rollers abutting against the outer wall of the bearing ring, a rack is installed at one end of the grinding roller, a fixing rod is arranged between the plurality of racks, two first gears are installed on the outer wall of the fixing rod, and the two first gears are respectively meshed and connected with two of the racks.

[0006] Furthermore, a limiting ring is installed on the outer wall of the grinding roller, and the outer wall of the limiting ring abuts against the outer wall of the bearing ring.

[0007] Furthermore, a mounting plate is installed at one end of the grinding roller, the outer wall of the rack is connected to the outer wall of the mounting plate, a guide rod is installed on the outer wall of the mounting plate, and the rack is slidably connected to the outer wall of the guide rod.

[0008] Furthermore, a support frame is arranged on the periphery of the bearing ring, and a plurality of slide grooves are opened on the support frame. A mounting rod is installed on the inner wall of the grinding roller, and one end of the mounting rod extends from the outside of the grinding roller to the inside of the slide groove, and the mounting rod is slidably connected to the slide groove.

[0009] Furthermore, a baffle is installed at one end of the mounting rod away from the grinding roller, and an outer wall of the baffle abuts against an outer wall of the support frame.

[0010] Furthermore, the fixing rod is rotatably connected to the support frame, and a knob is installed on one end of the fixing rod extending to the outside of the support frame.

[0011] Furthermore, a second gear is installed on the outer wall of the fixing rod, a fixing frame is installed on the outer wall of the supporting frame, a clamping block is inserted into the fixing frame, a pull rod is installed on the outer wall of the clamping block, the pull rod is plugged into the fixing frame, a pull plate is installed on one end of the pull rod, and a spring is connected between the clamping block and the inner wall of the fixing frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the two first gears are rotated by twisting the fixing rod, thereby driving the rack to move and pull the grinding roller to clamp the bearing ring. After the servo motor drives the grinding rod to rotate and grinds the inner wall of the bearing ring, the grinding roller is moved away from the bearing ring but keeps contact with the outer wall. When the grinding rod is rotated again, the bearing ring will rotate together. At this time, the outer wall of the bearing ring will rub the grinding roller, so that both the inside and the outside can be ground without removing the bearing ring.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] See also Figure 1-Figure 4 As shown, a surface grinding device with a synchronous grinding function of inner and outer rings includes a bearing ring 1, a grinding fixing assembly 2 is arranged on the periphery of the bearing ring 1, and the grinding fixing assembly 2 includes a plurality of grinding rollers 201 that abut against the outer wall of the bearing ring 1, a rack 202 is fixedly installed at one end of the grinding roller 201, a fixing rod 203 is arranged between the plurality of racks 202, and two first gears 204 are fixedly installed on the outer wall of the fixing rod 203, and the two first gears 204 are respectively meshed and connected with two of the racks 202, wherein the length of the two grinding rollers 201 is longer than that of the other two. The two grinding rollers 201 are relatively short in length, and two grinding rods 205 are connected to the inner wall of the bearing ring 1. The outer wall of the grinding rod 205 is against the inner wall of the bearing ring 1. A fixed plate 206 is provided on one side of the bearing ring 1, and one end of the two grinding rods 205 is fixedly connected to the outer wall of the fixed plate 206. A servo motor 207 is provided on one side of the bearing ring 1, and the driving end of the servo motor 207 is connected to the outer wall of the fixed plate 206. A U-shaped support plate 208 is provided on one side of the bearing ring 1, and the servo motor 207 is fixedly installed on the top of the U-shaped support plate 208.

[0026] The fixing rod 203 is turned to drive the two first gears 204 to rotate. The two first gears 204 are respectively meshed with two of the racks 202. Therefore, when the two first gears 204 rotate simultaneously, the racks 202 are driven to move together. After the fixing rod 203 and the first gears 204 are rotated counterclockwise, the racks 202 move relatively and pull the grinding roller 201 toward the bearing ring 1. When the fixing rod 203 and the first gears 204 are rotated clockwise, the racks 202 move away from each other and the grinding roller 201 moves away from the bearing ring 1.

[0027] When the grinding roller 201 approaches the bearing ring 1 and clamps the bearing ring 1, the bearing ring 1 cannot be moved at this time, and then the servo motor 207 drives the fixed plate 206 to rotate, and the fixed plate 206 drives the two grinding rods 205 to rotate along the inner wall of the bearing ring 1 to grind the inner wall of the bearing ring 1;

[0028] When the inner wall of the bearing ring 1 is polished, the polishing roller 201 is moved a short distance away from the bearing ring 1 so that the bearing ring 1 is in contact and clamped, but the polishing roller 201 is still in contact with the outer wall of the bearing ring 1. At this time, when the servo motor 207 drives the fixed plate 206 and the polishing rod 205 to rotate, the bearing ring 1 will rotate with the polishing rod 205, and then the outer wall of the bearing ring 1 will rub against the outer wall of the polishing roller 201, thereby polishing the outer wall of the bearing ring 1.

[0029] See also Figure 1-Figure 3 A limiting ring 4 is fixedly mounted on the outer wall of the grinding roller 201 , and the outer wall of the limiting ring 4 abuts against the outer wall of the bearing ring 1 .

[0030] The limiting ring 4 limits and blocks the bearing ring 1 to prevent the bearing ring 1 from falling off between the multiple grinding rollers 201 during grinding, thereby avoiding damage to the bearing ring 1.

[0031] See also Figure 1-Figure 3 A mounting plate 5 is fixedly mounted on one end of the grinding roller 201, the outer wall of the rack 202 is fixedly connected to the outer wall of the mounting plate 5, a guide rod 6 is fixedly mounted on the outer wall of the mounting plate 5, and the rack 202 is slidably connected to the outer wall of the guide rod 6.

[0032] The mounting plate 5 is fixed on one end of the grinding roller 201 to support the rack 202, so that the rack 202 can pull the grinding roller 201 to move through the mounting plate 5 when moving. At the same time, the mounting plate 5 fixes the position of the guide rod 6, so that the rack 202 can slide along the outer wall of the guide rod 6 when following the movement of the first gear 204, making the rack 202 more stable.

[0033] See also Figure 1-Figure 4 A support frame 3 is arranged on the periphery of the bearing ring 1, and a plurality of slide grooves 7 are opened on the support frame 3. A mounting rod 9 is fixedly installed on the inner wall of the grinding roller 201. One end of the mounting rod 9 extends from the outside of the grinding roller 201 to the inside of the slide groove 7, and the mounting rod 9 is slidably connected to the slide groove 7.

[0034] The support frame 3 supports the bearing ring 1 and the grinding fixing assembly 2. The grinding roller 201 is connected to the support frame 3 through the mounting rod 9, so that the grinding roller 201 can slide along the support frame 3 through the mounting rod 9 when moving, so that the grinding roller 201 can be stable. At the same time, in order not to affect the movement of the grinding roller 201, the sliding groove 7 is used to provide the mounting rod 9 with sliding space and direction to prevent the support frame 3 and the mounting rod 9 from affecting the movement of the grinding roller 201.

[0035] See also Figure 2-Figure 3 A baffle plate 8 is fixedly mounted on one end of the mounting rod 9 away from the grinding roller 201 , and the outer wall of the baffle plate 8 abuts against the outer wall of the support frame 3 .

[0036] The baffle 8 blocks one end of the mounting rod 9 to prevent the mounting rod 9 from sliding out of the slide groove 7. Meanwhile, the connection between the slide groove 7 and the support frame 3 also prevents the grinding roller 201 from tilting easily.

[0037] See also Figure 2 The fixing rod 203 is rotatably connected to the support frame 3 , and a knob 11 is fixedly mounted on one end of the fixing rod 203 extending to the outside of the support frame 3 .

[0038] The knob 11 enables the fixing rod 203 to be manipulated more easily. The user only needs to hold the knob 11 and turn it to drive the fixing rod 203 to rotate, and no tools are needed to rotate the fixing rod 203.

[0039] See also Figure 2 and Figure 5 A second gear 10 is fixedly installed on the outer wall of the fixing rod 203, a fixing frame 12 is fixedly installed on the outer wall of the support frame 3, a clamping block 13 is inserted into the fixing frame 12, one end of the clamping block 13 extending out of the fixing frame 12 is clamped with the second gear 10, a pull rod 14 is fixedly installed on the outer wall of the clamping block 13, one end of the pull rod 14 extends to the outside of the fixing frame 12, the pull rod 14 is plugged into the fixing frame 12, a pull plate 16 is fixedly installed on the end of the pull rod 14 away from the clamping block 13, and a spring 15 is connected between the clamping block 13 and the inner wall of the fixing frame 12.

[0040] Before turning the fixing rod 203 to rotate, first pull the pull plate 16 to drive the pull rod 14 and the block 13 to move, so that the block 13 is away from the tooth gap of the second gear 10, and then turn the fixing rod 203 to adjust the position of the grinding roller 201. After releasing the pull plate 16, the spring 15 will push the block 13 back to its original position, so that the block 13 is stuck in the tooth gap of the second gear 10, so that the fixing rod 203 cannot be rotated. This structure prevents the force generated by the grinding rod 205 during rotation from being brought to the grinding roller 201 through the bearing ring 1 and causing the grinding roller 201 to loosen, so that the bearing ring 1 can be fixed more stably.

[0041] Working principle:

[0042] The fixing rod 203 is turned to drive the two first gears 204 to rotate. The two first gears 204 are respectively meshed with two of the racks 202. Therefore, when the two first gears 204 rotate simultaneously, the racks 202 are driven to move together. After the fixing rod 203 and the first gears 204 are rotated counterclockwise, the racks 202 move relatively and pull the grinding roller 201 toward the bearing ring 1. When the fixing rod 203 and the first gears 204 are rotated clockwise, the racks 202 move away from each other and the grinding roller 201 moves away from the bearing ring 1.

[0043] When the grinding roller 201 approaches the bearing ring 1 and clamps the bearing ring 1, the bearing ring 1 cannot be moved at this time, and then the servo motor 207 drives the fixed plate 206 to rotate, and the fixed plate 206 drives the two grinding rods 205 to rotate along the inner wall of the bearing ring 1 to grind the inner wall of the bearing ring 1;

[0044] When the inner wall of the bearing ring 1 is polished, the polishing roller 201 is moved a short distance away from the bearing ring 1 so that the bearing ring 1 is in contact and clamped, but the polishing roller 201 is still in contact with the outer wall of the bearing ring 1. At this time, when the servo motor 207 drives the fixed plate 206 and the polishing rod 205 to rotate, the bearing ring 1 will rotate with the polishing rod 205, and then the outer wall of the bearing ring 1 will rub against the outer wall of the polishing roller 201, thereby polishing the outer wall of the bearing ring 1.

[0045] Before turning the fixing rod 203 to rotate, first pull the pull plate 16 to drive the pull rod 14 and the block 13 to move, so that the block 13 is away from the tooth gap of the second gear 10, and then turn the fixing rod 203 to adjust the position of the grinding roller 201. After releasing the pull plate 16, the spring 15 will push the block 13 back to its original position, so that the block 13 is stuck in the tooth gap of the second gear 10, so that the fixing rod 203 cannot be rotated. This structure prevents the force generated by the grinding rod 205 during rotation from being brought to the grinding roller 201 through the bearing ring 1 and causing the grinding roller 201 to loosen, so that the bearing ring 1 can be fixed more stably.
