Description

Technical Field

[0001] The utility model relates to the technical field of bearing outer ring processing, in particular to a positioning and adjusting die for bearing outer ring processing. Background Technique

[0002] The bearing ring is an annular part of a radial rolling bearing with one or several raceways. The bearing ring is divided into the structures of bearing outer ring and bearing inner ring. When installing the bearing ring, special attention should be paid to the installation sequence, and for precision bearings, the positive and negative ends should also be noted.

[0003] When processing the bearing outer ring, it is necessary to fix the bearing first to prevent the bearing from shaking during the milling of the bearing outer ring and affecting the processing effect. However, most of the current bearing outer ring fixing devices directly clamp and fix the outer wall of the outer ring. During processing, as the milling position changes, the bearing outer ring will move back and forth, thereby affecting the accuracy of the bearing outer ring processing. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a positioning and adjusting die for bearing outer ring processing, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions:

[0006] The utility model discloses a positioning and adjusting die for bearing outer ring processing, including a placement plate,

[0007] A lead screw, assembled with the placement plate through an installation groove opened on the surface of the placement plate;

[0008] A first guide rod, fixed in the installation groove on the side of the placement plate away from the lead screw;

[0009] A first fixing block, divided into two groups and symmetrically and movably installed on the top of the placement plate;

[0010] A connecting sleeve, fixed at the bottoms on both sides of the first fixing block, and respectively sleeved with the lead screw and the first guide rod. By rotating the lead screw, the centering of the bearing outer ring is realized to determine the positioning during the processing of the bearing outer ring;

[0011] A screw rod, movably installed at the top of the included angle of the first fixing block;

[0012] A second fixing block, installed above the first fixing block and also sleeved with the screw rod. By rotating the screw rod, the distance between the second fixing block and the first fixing block can be controlled;

[0016] Furthermore, connecting rods are installed in the movable holes of the connecting plates, and the connecting plates of the two groups of second fixing blocks are sleeved with the connecting rods.

[0017] Furthermore, supporting plates are fixed at both ends of the placing plate, and guiding grooves are formed at the positions of the supporting plates corresponding to the connecting rods.

[0018] Furthermore, a plurality of discharging ports are formed on the surfaces of the connecting plates.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. In the utility model, the first fixing blocks can be made to approach each other through the lead screw to perform centering positioning on the outer ring of the bearing.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4 , including a placement plate 1, a lead screw 2, which is assembled with the placement plate 1 through an installation groove opened on the surface of the placement plate 1, and one end of the lead screw 2 is connected to a motor; a first guide rod 3, fixed in the installation groove on the side of the placement plate 1 away from the lead screw 2; a first fixing block 4, divided into two groups and symmetrically and movably installed on the top of the placement plate 1. The first fixing block 4 is L-shaped, with an anti-slip strip adhered to the inner wall, forming an included angle inside. The outer wall of the outer ring of the bearing is fitted with the inner wall of the included angle of the first fixing block 4, which can limit the outer ring of the bearing. The two groups of first fixing blocks 4 approach each other, forming a clamping state for the outer ring of the bearing to fix the outer ring of the bearing; a connecting sleeve 5, fixed at the bottoms on both sides of the first fixing block 4 and sleeved with the lead screw 2 and the first guide rod 3 respectively. A threaded groove is opened on the side of the connecting sleeve 5 that fits the lead screw 2. By driving the lead screw 2 to rotate through the motor, the connecting sleeve 5 drives the first fixing block 4 to move, and the threaded grooves of the two groups of first fixing blocks 4 are opened in the reverse direction, so that the two groups of first fixing blocks 4 can approach or move away at the same time, thereby realizing the centering effect of the outer ring of the bearing and facilitating the determination of the positioning during the processing of the outer ring of the bearing; a screw 6, movably installed at the top of the included angle of the first fixing block 4; a second fixing block 8, installed above the first fixing block 4 and also sleeved with the screw 6. By rotating the screw 6, the distance between the second fixing block 8 and the first fixing block 4 can be controlled; a fixing plate 9, fixed at the top of the second fixing block 8 and extending towards the inside of the included angle. When the first fixing block 4 is driven to move by the lead screw 2, the second fixing block 8 moves with the first fixing block 4 through the screw 6. By rotating the screw 6, the second fixing block 8 can be moved downward so that the second fixing block 8 fits against the outer wall of the outer ring of the bearing, enabling the fixing plate 9 to press on the top of the outer ring of the bearing. The outer ring of the bearing is further fixed by the fixing plate 9 and the placement plate 1 to reduce the problem of movement during the processing of the outer ring of the bearing.

[0029] A second guide rod 7 is fixed at the top of the group of first fixing blocks 4 away from the screw 6, and the second guide rod 7 is symmetrically arranged with the screw 6.

[0030] Two connecting plates 10 are fixed on both sides of the second fixed block 8, and movable holes are formed on the surfaces of the connecting plates 10. A connecting rod 11 is installed in the movable holes of the connecting plates 10, and the connecting plates 10 of the two groups of second fixed blocks 8 are sleeved on the connecting rod 11. Support plates are fixed at both ends of the placing plate 1, and guide grooves 12 are formed at positions corresponding to the connecting rod 11 on the support plates. The connecting rod 11 passes through the inside of the guide grooves 12. When the second fixed block 8 moves with the first fixed block 4, the connecting plate 10 moves along the connecting rod 11 through the movable hole. When the second fixed block 8 rotates and descends along with the screw rod 6, the two groups of second fixed blocks 8 move simultaneously along with the connection of the connecting rod 11. And as the second fixed block 8 moves, the end part of the connecting rod 11 moves inside the guide groove 12 and moves smoothly through the guidance of the guide groove 12.

[0031] A plurality of discharge ports 13 are formed on the surface of the connecting plate 10. When the outer ring of the bearing is milled, the excess waste can fall below the placing plate 1 through the discharge ports 13, avoiding the accumulation of waste on the surface of the placing plate 1 and affecting the processing efficiency of the outer ring of the bearing.

[0032] Working principle: Move the first fixed block 4 through the lead screw 2 to make the two groups of first fixed blocks 4 move away from each other, so as to reserve enough positions on the surface of the placing plate 1 for placing the outer ring of the bearing. Send the outer ring of the bearing from the side of the placing plate 1 away from the first fixed block 4 between the two groups of first fixed blocks 4. After the outer ring of the bearing is placed on the surface of the placing plate 1, move the first fixed block 4 towards the outer ring of the bearing through the lead screw 2. After the outer ring of the bearing contacts the first fixed block 4, it is pushed by the first fixed block 4 until the outer wall of the outer ring of the bearing fits and fixes with the two groups of first fixed blocks 4, completing the centering and positioning. After the inner wall of the first fixed block 4 fits with the outer wall of the outer ring of the bearing, the anti-slip strips on the inner wall of the first fixed block 4 can effectively prevent the movement of the outer ring of the bearing. When the first fixed block 4 moves, the second fixed block 8 moves towards the outer ring of the bearing together under the drive of the screw rod 6 and the second guide rod 7. After the first fixed block 4 fixes the outer wall of the outer ring of the bearing, rotate the screw rod 6 to make the second fixed block 8 move towards the top of the outer ring of the bearing. When the screw rod 6 drives one group of second fixed blocks 8 to move, the other group of second fixed blocks 8 moves together under the drive of the connecting rod 11, so that the two groups of second fixed blocks 8 fall on the top of the outer ring of the bearing at the same time. After the second fixed block 8 moves a certain distance, the fixing plate 9 abuts against the top of the outer ring of the bearing, so that the top and bottom of the bearing are restricted from moving by the placing plate 1 and the fixing plate 9, strengthening the fixing effect of the outer ring of the bearing, avoiding the movement problem of the outer ring of the bearing changing with the milling position during processing, and improving the accuracy during the processing of the outer ring of the bearing.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made therein without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
