[0002] Bearings are essential components in modern machinery. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Spacers are a component within bearings, primarily used to maintain a specified axial distance between two bearing rings or washers. Bearing production requires machining the inner and outer rings. Current tooling systems lack the ability to center the inner and outer rings, leading to eccentricity during adjustments to the machining position and affecting the bearing's machining accuracy. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling structure for bearing processing, which can center the bearing parts and expose the outer wall processing position, thus facilitating processing and improving processing efficiency.

[0004] The purpose of this utility model is achieved through the following technical solution: a tooling structure for bearing processing, including a tooling base, on which clamping mechanisms are arranged opposite each other. The clamping mechanism includes a sliding plate, a centering cone, a clamping ring, and a rotating plate. A clamping space is formed between the sliding plates of the two clamping mechanisms. The sliding plate is slidably disposed on the tooling base for adjusting the size of the clamping space. The rotating plate is rotatably disposed on the end face of the sliding plate near the clamping space. The centering cone is coaxially disposed on the rotating plate. The diameter of the centering cone gradually increases along the direction close to the sliding plate. The clamping ring is slidably sleeved on the centering cone. The outer diameter of the clamping ring is larger than the inner diameter of the part, and the outer diameter of the clamping ring is smaller than the outer diameter of the part.

[0005] Furthermore, a small-diameter shaft is provided between the centering cone and the rotating plate. The small-diameter shaft is coaxially fixed to the rotating plate. The end of the small-diameter shaft away from the rotating plate is provided with an external thread. The large-diameter end of the centering cone is provided with an internal threaded hole. The small-diameter shaft is threaded into the internal threaded hole.

[0006] Furthermore, it also includes a drive plate, and multiple connecting strips are fixed to the end face of the clamping ring near the rotating plate. The multiple connecting strips are evenly distributed along the circumference of the clamping ring. The connecting strips movably pass through the rotating plate and connect to the drive plate. The drive plate moves along the axial direction of the rotating plate.

[0007] Furthermore, an electric push rod is provided between the drive plate and the rotating plate, the cylinder of the electric push rod is mounted on the rotating plate, and the telescopic shaft of the electric push rod is connected to the drive plate.

[0008] Furthermore, the drive plate has a through hole through which the connecting strip passes, and two nuts are threaded onto the connecting strip, with the two nuts respectively abutting against both ends of the drive plate in the axial direction.

[0009] Furthermore, a mounting hole is provided through the sliding plate, and a bearing is fitted onto the rotating plate, with the outer ring of the bearing installed in the mounting hole.

[0010] Furthermore, a large gear is mounted on one of the rotating plates, a motor is mounted on the sliding plate, the output shaft of the motor is connected to a small gear, and the large gear meshes with the small gear.

[0011] Furthermore, the tooling base is provided with a lead screw groove, and a bidirectional threaded lead screw is rotatably arranged in the lead screw groove. A lead screw slider is threadedly fitted on the two threaded sections of the bidirectional threaded lead screw with opposite directions. The two sliding plates are respectively connected to the two lead screw sliders. A lead screw motor is provided at one end of the tooling base, and the output shaft of the lead screw motor is connected to one end of the bidirectional threaded lead screw through a coupling.

[0012] The beneficial effects of this utility model are:

[0013] Two centering cones are inserted into the inner holes at both ends of the part. The two sliding plates move closer to each other, causing the centering cones to gradually adjust the position of the part. When the centering cones come into contact with the part, the part and the centering cones are in a coaxial state, completing the concentric tooling of the part. At the same time, the outer wall machining position is fully exposed, which facilitates machining and improves machining efficiency. Attached Figure Description

Detailed Implementation

[0018] like Figures 1 to 3 As shown, a tooling structure for bearing machining includes a tooling base 1. Clamping mechanisms are arranged opposite each other on the tooling base 1. Each clamping mechanism includes a sliding plate 2, a centering cone 3, a clamping ring 4, and a rotating plate 5. A clamping space is formed between the sliding plates 2 in the two clamping mechanisms. The sliding plates 2 are slidably mounted on the tooling base 1 to adjust the size of the clamping space. A rotating plate 5 is rotatably mounted on the end face of the sliding plate 2 near the clamping space. A centering cone 3 is coaxially mounted on the rotating plate 5. The diameter of the centering cone 3 gradually increases along the direction close to the sliding plate 2. The clamping ring 4 is slidably sleeved on the centering cone 3. The outer diameter of the clamping ring 4 is larger than the inner diameter of the part, and the outer diameter of the clamping ring 4 is smaller than the outer diameter of the part. A ring-shaped part is fitted onto one of the centering cones 3. Then, the two sliding plates 2 move closer to each other, causing the two centering cones 5 to... The centering cone 3 is inserted into the inner holes at both ends of the part. Under the action of the conical surface of the centering cone 3, the position of the part is adjusted so that the centering cone 3 abuts against the part, and the part and the centering cone 3 are in a coaxial state, completing the concentric tooling of the part. Then, the clamping ring 4 moves close to the part and clamps the part with the two clamping rings 4 to increase the contact area of ​​the part tooling and prevent the force between the centering cone 3 and the inner ring of the ring part from continuously increasing and damaging the ring part. Since the outer diameter of the clamping ring 4 is larger than the inner diameter of the part and the outer diameter of the clamping ring 4 is smaller than the outer diameter of the part, the clamping ring 4 will not bulge out from the outer ring of the part and will not interfere with the processing equipment. At the same time, the outer wall processing position is fully exposed, which facilitates processing and improves processing efficiency. The part is rotated by the rotating plate 5 to adjust its processing position.

[0019] Furthermore, such as Figure 2 As shown, a lead screw groove 15 is provided on the tooling base 1, and a bidirectional threaded lead screw 16 is rotatably arranged in the lead screw groove 15. A lead screw slider 17 is threadedly fitted on the two threaded sections of the bidirectional threaded lead screw 16 with opposite threads. Two sliding plates 2 are respectively connected to the two lead screw sliders 17. A lead screw motor 18 is provided at one end of the tooling base 1. The output shaft of the lead screw motor 18 is connected to one end of the bidirectional threaded lead screw 16 through a coupling. The lead screw motor 18 drives the bidirectional threaded lead screw 16 to rotate. Since the threads of the two lead screw sliders 17 have opposite threads, the two lead screw sliders 17 move in opposite directions, thereby adjusting the distance between the two sliding plates 2 and completing the tooling of the part.

[0020] Furthermore, such as Figure 1As shown, a small-diameter shaft 6 is provided between the centering cone 3 and the rotating plate 5. The small-diameter shaft 6 is coaxially fixed to the rotating plate 5. The end of the small-diameter shaft 6 away from the rotating plate 5 is provided with an external thread. The large-diameter end of the centering cone 3 is provided with an internal threaded hole. The small-diameter shaft 6 is threaded into the internal threaded hole. The centering cone 3 is detachably connected. The matching centering cone 3 is installed according to the size of the part. The centering cone 3 is installed by thread. The installation and disassembly are simple and quick.

[0021] Furthermore, it also includes a drive plate 8. Multiple connecting strips 7 are fixed to the end face of the clamping ring 4 near the rotating plate 5. The multiple connecting strips 7 are evenly distributed along the circumference of the clamping ring 4. The connecting strips 7 move through the rotating plate 5 and connect to the drive plate 8. The drive plate 8 moves along the axial direction of the rotating plate 5. An electric push rod 9 is provided between the drive plate 8 and the rotating plate 5. The cylinder of the electric push rod 9 is mounted on the rotating plate 5. The telescopic shaft of the electric push rod 9 is connected to the drive plate 8. The clamping ring 4 and the centering cone 3 are coaxially arranged. The drive plate 8 is moved by the telescopic movement of the electric push rod 9. The drive plate 8 drives the clamping ring 4 to move through the connecting strips 7, thus completing the clamping fixture for the part.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, a through hole is provided on the drive plate 8 for the connecting strip 7 to pass through. Two nuts 10 are threaded onto the connecting strip 7, and the two nuts 10 abut against the two ends of the drive plate 8 in the axial direction. The clamping ring 4 is installed in a detachable manner, so that the corresponding clamping ring 4 can be installed according to the size of the part, and the size of the clamping ring 4 is such that the outer diameter of the clamping ring 4 is greater than the inner diameter of the part and the outer diameter of the clamping ring 4 is smaller than the outer diameter of the part. When replacing, remove the nut 10 away from the centering cone 3, separate the connecting strip 7 from the drive plate 8, and finally move the clamping ring 4 in the direction away from the centering cone 3 to remove the clamping ring 4. Then replace the corresponding clamping ring 4 by passing the connecting strip 7 of the clamping ring 4 through the rotating plate 5 and the drive plate 8, and finally screw on the nut 10. This allows both the clamping ring 4 and the centering cone 3 to be replaced according to the size of the part, resulting in better tooling effect for the part.

[0023] Furthermore, a mounting hole 11 is provided through the sliding plate 2, and a bearing is fitted on the rotating plate 5. The outer ring of the bearing is installed in the mounting hole 11. A large gear 12 is fitted on one of the rotating plates 5, and a motor 13 is installed on the sliding plate 2. The output shaft of the motor 13 is connected to a small gear 14. The large gear 12 meshes with the small gear 14. The motor 13 drives the rotating plate 5 to rotate through the meshing of the large gear 12 and the small gear 14, thereby causing the part to deflect and adjust the processing position.
