Description

Technical Field

[0001] The utility model belongs to the technical field of bearing ring processing, in particular to a bearing ring lapping and clamping device. Background Art

[0002] Bearing rings are annular parts of centripetal rolling bearings with one or more raceways. When processing bearing rings, a clamping mechanism is often required to clamp and fix the rings. However, most clamping devices currently clamp and fix the bearing rings from the outside and cannot clamp and fix the bearing rings from the inside. When clamping the bearing rings from the outside, the outside of the bearing rings will press against the clamping device, and the operating space is very narrow, making it difficult to process the outside of the bearing rings, thereby bringing inconvenience to the processing of the bearing rings.

[0003] For example, the existing Chinese publication number CN219075604U describes a bearing ring clamp for easy clamping, which "comprises a workbench, the top of which is fixedly connected to a fixing seat and a mounting seat, wherein the fixing seat is located to the left of the mounting seat, and two limiting rods are fixedly connected to the right side wall of the fixing seat, and the limiting rods are symmetrically arranged on the front and rear sides of the fixing seat."

[0004] It can be seen that the cited patent document has the problem that it is difficult to clamp the bearing ring from the inside. Utility Model Content

[0005] The purpose of the utility model is to provide a bearing ring lapping and clamping device to solve the problems raised in the background technology.

[0006] The top end of the threaded shaft is also rotatable with a top block, and the bottom end of the threaded shaft is rotatable with a top block, and the bottom end of the threaded shaft is rotatable with a top block, and the bottom end of the threaded shaft is rotatable with a top block.

[0007] Preferably, a through slot is provided on the top surface of the clamping platform for the threaded shaft and the hinge plate to pass through, and sliding rods are provided on both sides of the through slot through sliding grooves.

[0008] Preferably, an inverted T-shaped limit block is welded to the bottom surface of the two clamping blocks, and the two limit blocks are slidably sleeved on the peripheral sides of the two sliding rods respectively.

[0009] Preferably, the clamping assembly includes a bidirectional threaded rod and two pressing blocks, and both ends of the bidirectional threaded rod are rotatably connected to the inner side wall of the clamping platform through a pin shaft.

[0010] Preferably, the two pressing blocks are both threadedly sleeved on the circumference of the bidirectional threaded rod, and the two pressing blocks are both arranged in an inverted L shape.

[0011] Preferably, a limit rod is installed on one side of the top surface of the clamping table through a transverse groove, and vertical blocks that are slidably sleeved on the circumference of the limit rod are welded to the bottom surfaces of the two pressing blocks.

[0012] Preferably, a side surface and a top surface of the bracket are both provided with through holes, the inner side walls of the two through holes are both installed with bearings, and the rotating rod and the threaded shaft respectively pass through the bearings and are fixedly connected to the inner side walls of the bearings.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are:

[0014] The bearing ring lapping and clamping device can provide power for the threaded shaft to rotate by rotating the rotating rod, allowing the movable block to achieve longitudinal reciprocating motion, thereby allowing the two clamping blocks to achieve lateral motion, and clamping and fixing the inner side of the bearing ring. Compared with the existing device that can only clamp and fix the outer side of the bearing ring, this device can not only clamp the outer side of the bearing ring, but also clamp the inner side, which facilitates the processing of the outer side of the bearing ring, saving both time and effort.

[0015] The setting of the clamping assembly can clamp the outer side of the bearing ring, and can process the inner side of the bearing ring. The position of the rotating rod and the threaded shaft can be supported by the through hole and the fixed bearing, and will not affect the rotation between the rotating rod and the threaded shaft. The setting of the welded limit block and the sliding rod can limit the position of the two clamping blocks to prevent the two clamping blocks from offsetting. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The top end of the threaded shaft 4 is also rotationally connected with a top block 9 through a pin shaft, the bottom ends of the two top blocks 9 are welded on the top surface of the support 2, the bottom surface of the top block 9 is symmetrically welded with two vertical rods 10, the movable block 6 is slidably sleeved on the circumferential side of the two vertical rods 10, when the movable block 6 moves longitudinally, it moves reciprocatingly on the circumferential side of the two vertical rods 10, so that the vertical rods 10 can limit the position of the movable block 6, avoiding rotating with the threaded shaft 4.

[0031] The inner cavity of the clamping table 1 is provided with a clamping assembly for fixing the outer side of the bearing ring, the clamping assembly comprises a bidirectional threaded rod 14 and two pressing blocks 15, both ends of the bidirectional threaded rod 14 are rotatably connected to the inner side wall of the clamping table 1 through a pin shaft, and one end of the bidirectional threaded rod 14 is also connected with a handle through a circular hole on one side of the clamping table 1, both pressing blocks 15 are threadedly sleeved on the side of the bidirectional threaded rod 14, both pressing blocks 15 are arranged in an inverted L shape, a through slot is formed in one side of the top surface of the clamping table 1 for the two pressing blocks 15, the upper half of both pressing blocks 15 passes through the through slot and is above the clamping table 1, and the opposite side surface of both pressing blocks 15 is provided with an arc-shaped groove for clamping the bearing ring, when the inner side of the bearing ring needs to be machined, the handle is first rotated, and then the two pressing blocks 15 are driven by the bidirectional threaded rod 14 to move in opposite directions, so that the distance between the two pressing blocks 15 is less than the diameter of the bearing ring, and the bearing ring is placed on the inner bottom surface of the two arc-shaped grooves, at this time, the handle is continuously rotated, so that the inner side wall of the two arc-shaped grooves abuts against the outer side of the bearing ring, and the outer side of the bearing ring is clamped and fixed, thereby facilitating the machining of the inner side of the bearing ring.

[0032] Both pressing blocks 15 are above the two clamping blocks 8, so that the clamping block 8 does not affect the machining of the inner side of the bearing ring.

[0033] A limiting rod 17 is mounted on one side of the top surface of the clamping table 1 through a horizontal groove, and a vertical block 16 is welded to the bottom surface of each pressing block 15 and slidably sleeved on the side of the limiting rod 17, so that the vertical block 16 moves along the side of the limiting rod 17 when the pressing block 15 moves, thereby assisting the movement of the pressing block 15 and limiting the position of the pressing block 15 to avoid deviation.

[0034] The side surface and the top surface of the bracket 2 are provided with through holes 18, and the inner side walls of the two through holes 18 are provided with bearings 19, the outer peripheries of the two bearings 19 are connected and fixed to the inner walls of the two through holes 18, the rotating rod 3 and the threaded shaft 4 pass through the bearings 19 and are connected and fixed to the inner side walls of the bearings 19, so that when the rotating rod 3 and the threaded shaft 4 rotate, the inner rings of the bearings 19 are driven to rotate, the bearings 19 can support the positions of the rotating rod 3 and the threaded shaft 4, and the rotation between the rotating rod 3 and the threaded shaft 4 is not affected.
