Description

Technical Field

[0001] This utility model relates to the field of bearing ring inclined oil hole processing technology, and specifically discloses a multi-size bearing ring inclined oil hole processing device. Background Technology

[0002] As a core component of rolling bearings, the structural precision of bearing rings directly affects the bearing's load-bearing capacity and service life. The angled oil hole, as a critical lubrication channel for the ring, has its machining quality crucial for the bearing's heat dissipation performance and lubrication efficiency.

[0003] A multi-size bearing ring inclined oil hole processing device, Chinese Patent No. CN210359362U, includes a frame and an operating table, with the operating table housed within the frame. An adjustment and positioning mechanism for fixing bearing rings of various sizes is installed on the operating table surface. Above and below the operating table are drilling mechanisms adapted to the bearing rings, and fixing mechanisms supporting the drilling mechanisms. This multi-size bearing ring inclined oil hole processing device adjusts the relative positions of the clamping blocks through the adjustment and positioning mechanisms to clamp and position bearing rings of different sizes. The fixing mechanisms fix the drilling mechanisms and maintain a certain tilt angle to prevent the electric drill from shifting during drilling, ensuring the drilling position and direction of the inclined oil hole. The drilling mechanism is designed as a telescopic structure to ensure that the electric drill bit is positioned at the drilling location of the inclined oil hole.

[0004] The above-mentioned device can clamp and fix bearing rings of different sizes. However, since the fixing method uses a return spring and clamping blocks to clamp and fix the bearing rings from multiple sides, it has the following drawbacks during use:

[0005] (1) The rigid support of the elastic clamping unit is insufficient, and micro-displacement is easily generated during the processing, which affects the positioning accuracy of the inclined oil hole.

[0006] (2) When more than two oil holes need to be machined, the workpiece angle adjustment relies on manual operation, making it difficult to achieve automated process connection for multiple oil holes. Therefore, a multi-size bearing ring inclined oil hole machining device is needed to solve this problem. Utility Model Content

[0007] This utility model proposes a multi-size bearing ring inclined oil hole processing device. By clamping and limiting the inner wall and both ends of the bearing ring, displacement of the bearing ring during drilling can be prevented. By adjusting the angle of the bearing ring, multi-position drilling processing of the bearing ring can be performed.

[0008] This utility model is implemented as follows: a multi-size bearing ring inclined oil hole processing device includes an L-shaped bracket. The bottom end of the L-shaped bracket is slidably connected to an installation frame. A first motor is installed inside the installation frame. The output end of the first motor passes through the installation frame and is fixedly connected to a U-shaped frame. A bidirectional lead screw is rotatably connected inside the U-shaped frame.

The left and right ends of the bearing ring are limited. The bearing rings of different sizes are clamped and fixed by the cooperation of the double screw, two drive blocks, two support rods and two support blocks to prevent the bearing rings from shifting during the processing.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-4A multi-size bearing ring inclined oil hole processing device includes an L-shaped bracket 1. The bottom end of the L-shaped bracket 1 is slidably connected to a mounting frame 9. A first motor 10 is installed inside the mounting frame 9. The output end of the first motor 10 passes through the mounting frame 9 and is fixedly connected to a U-shaped frame 11. A bidirectional lead screw 18 is rotatably connected inside the U-shaped frame 11. Two symmetrically distributed drive blocks 12 are threadedly connected to the outer wall of the bidirectional lead screw 18. A support rod 13 is fixedly connected to the left end of each of the two drive blocks 12. A support block 15 is fixedly connected to the left end of each of the two support rods 13. A threaded rod 16 is threadedly connected to the outer wall of each of the two support blocks 15. A limit block 14 is fixedly connected to the opposite side of each of the two support rods 13. The two limit blocks 14 are located on the same vertical line.

[0027] A drilling mechanism is located in the upper left corner inside the L-shaped bracket 1.

[0028] In this embodiment: During use, the bearing ring to be drilled is placed on the outer wall of the two support rods 13, so that the right end of the bearing ring abuts against the left end of the two limiting blocks 14. Then, the bidirectional lead screw 18 is driven to rotate, thereby driving the two drive blocks 12 connected to it to move in opposite directions, thereby driving the two support rods 13 and the two support blocks 15 to move in opposite directions. The inner wall of the bearing ring is clamped and fixed by the two support rods 13. Then, the two threaded rods 16 are rotated so that the right end of the two threaded rods 16 abuts against the left end of the bearing ring, thereby limiting the left and right ends of the bearing ring. This process prevents the bearing ring from shifting during processing.

[0029] The first motor 10 (worm gear self-locking motor) drives the U-shaped frame 11 to rotate, which in turn drives the bidirectional lead screw 18, two drive blocks 12, two support rods 13, two support blocks 15 and bearing rings to rotate, thereby adjusting the angle of the bearing rings and performing multiple hole machining operations on the bearing rings.

[0030] As a technical optimization of this utility model, the drilling mechanism includes a rectangular plate 3 fixedly connected to the inner wall of the L-shaped bracket 1. A first electric push rod 4 is installed on the outer wall of the rectangular plate 3. The output end of the first electric push rod 4 passes through the rectangular plate 3 and is fixedly connected to a support frame 5. A second motor 6 is installed inside the support frame 5. The output end of the second motor 6 passes through the support frame 5 and is fixedly connected to a drilling tool 7.

[0031] In this embodiment: the second motor 6 can drive the drilling tool 7 to rotate, and the first electric actuator 4 can drive the support frame 5, the second motor 6, and the drilling tool 7 to move.

[0032] As a technical optimization of this utility model, a vertical plate 8 is fixedly connected to the bottom of the L-shaped bracket 1, and a second electric push rod 2 is installed on the outer wall of the vertical plate 8. The output end of the second electric push rod 2 passes through the vertical plate 8 and is fixedly connected to the mounting frame 9.

[0033] In this embodiment, the mounting frame 9 can be moved by the second electric actuator 2.

[0034] As a technical optimization of this utility model, a third motor 17 is fixedly connected to the upper end of the U-shaped frame 11, and the output end of the third motor 17 passes through the U-shaped frame 11 and is fixedly connected to the bidirectional lead screw 18.

[0035] In this embodiment, the bidirectional lead screw 18 can be driven to rotate by the third motor 17 (worm gear self-locking motor).

[0036] As a technical optimization of this utility model, arc-shaped anti-slip pads are fixedly connected to the opposite sides of the two support rods 13.

[0037] In this embodiment, arc-shaped anti-slip pads are fixedly connected to the opposite sides of the two support rods 13, which can increase the stability of clamping the bearing ring.

[0038] As a technical optimization of this utility model, the right ends of both drive blocks 12 abut against the inner wall of the U-shaped frame 11.

[0039] In this embodiment, the right ends of both drive blocks 12 abut against the inner wall of the U-shaped frame 11, which can prevent the two drive blocks 12 from rotating axially.

[0040] As a technical optimization of this utility model, a camera 19 is installed on the outer wall of the support frame 5.

[0041] In this embodiment, the camera 19 is connected to an external display. By linking the camera 19 with the display, the operator can remotely observe the tool feed trajectory and the oil hole forming process, avoiding misjudgment caused by obstructed vision in traditional processing.

[0042] The working principle and usage process of this utility model are as follows: When in use, the bearing ring that needs to be drilled is placed on the outer wall of the two support rods 13, so that the right end of the bearing ring abuts against the left end of the two limiting blocks 14. Then, the bidirectional screw 18 is driven to rotate, thereby driving the two drive blocks 12 connected to it to move in opposite directions, which in turn drives the two support rods 13 and the two support blocks 15 to move in opposite directions. The inner wall of the bearing ring is clamped and fixed by the two support rods 13. Then, the two threaded rods 16 are rotated so that the right end of the two threaded rods 16 abuts against the left end of the bearing ring, thereby limiting the left and right ends of the bearing ring. This process prevents the bearing ring from shifting during the processing.

[0043] The first motor 10 drives the U-shaped frame 11 to rotate, which in turn drives the bidirectional lead screw 18, two drive blocks 12, two support rods 13, two support blocks 15 and bearing rings to rotate, thereby adjusting the angle of the bearing rings and performing multiple hole machining operations on the bearing rings.
