Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to an automatic clamping bearing processing device. Background Technology

[0002] When machining bearings, they need to be fixed to prevent them from shaking and affecting operation. A search revealed a Chinese patent publication number CN217942602U, which discloses an automatic clamping device for bearing machining. This device uses an electric push rod to drive a clamping block to clamp and fix the bearing, facilitating machining and allowing for easy adjustment of the clamping position, simplifying operation. However, this device has limitations in the number of bearings it can clamp; it can only clamp a single bearing and cannot clamp and process multiple bearings simultaneously. This results in frequent clamping and fixing of bearings when machining multiple bearings, making the operation cumbersome. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic clamping bearing processing device, which solves the problem mentioned in the background art that existing devices cannot simultaneously clamp and process multiple sets of bearings, thus requiring frequent clamping and fixing of bearings when processing multiple bearings.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic clamping bearing processing device, comprising a base, a worm gear, a first clamping block, a second clamping block, and a cylinder. Ear plates are welded to both sides of the base, and mounting bolts are inserted inside the ear plates. Worm gears are distributed on both sides of the base, with their surfaces rotatably connected to the base. One end of each worm gear is welded to a connecting rod. Two connecting rods are provided, with their ends welded to the ends of a sliding rod. The sliding rod is slidably connected to the ends of the first clamping block. A second clamping block is provided between the first clamping blocks, with its ends slidably connected to the sliding rod. The first clamping block is fitted onto the outside of the cylinder's telescopic end. The other end of the cylinder is welded to the surface of the connecting rod.

[0005] Preferably, two second clamping blocks are provided, and springs are provided between the two clamping blocks. A spring is also provided between the second clamping block and the first clamping block. The springs are fitted outside the slide rod. When the cylinder extension end retracts, the springs help to open the first clamping block and the second clamping block apart, thereby facilitating the clamping and fixing of the bearing in the next placement.

[0006] Preferably, one side of the first clamping block and both sides of the second clamping block have an arc-shaped structure, and an arc-shaped groove is formed on the surface of one side of the first clamping block and both sides of the second clamping block. The surface of the groove is coated with a rubber coating. The arc-shaped surface helps the bearing surface to fully contact the first clamping block and the second clamping block, thereby improving the clamping surface and thus improving the clamping firmness.

[0007] Preferably, one side of the worm wheel is meshed with the worm, one bottom end of the worm is rotatably connected to the inside of the connecting block, both sides of the connecting block are welded to the base, and one top end of the worm is welded to the turntable. By rotating the turntable, the turntable can drive the worm to rotate, and the worm can drive the worm wheel to rotate at the same time. This facilitates the worm wheel to drive the two connecting rods to rotate, which in turn facilitates the adjustment of the gear fixing angle and the bearing fixing angle.

[0008] Preferably, when the two cylinder extension ends are extended, the first clamping block and the second clamping block are in contact with each other, and two adjacent second clamping blocks are in contact with each other. When a single bearing is fixed, the first clamping block will push the second clamping block to fix the bearing between the second clamping blocks, thereby enabling the device to fix different numbers of bearings.

[0009] This utility model provides an automatic clamping device for bearing processing. It has the following advantages:

[0010] (1) The automatic clamping bearing processing device, when in use, places multiple bearings between a first clamping block and a second clamping block respectively, and then pushes the first clamping block from both sides by a cylinder, so that the first clamping block can slide in relative directions, thereby clamping the bearing between the first clamping block and the second clamping block. As the cylinder extension end continues to extend, the bearing between the two second clamping blocks can be fixed. Thus, the device can fix multiple bearings at the same time when in use, which helps to avoid frequent clamping and fixing of bearings when multiple bearings are being processed.

[0011] (2) In this automatic clamping bearing processing device, after the first clamping block and the second clamping block clamp and fix the bearing, the turntable is rotated so that the turntable can drive the worm to rotate. When the worm rotates, it can drive the worm wheel to rotate, which in turn makes it easier for the worm wheel to drive the two connecting rods to rotate. This makes it easier to adjust the angle of the gear fixation, which in turn makes it easier to adjust the angle of the bearing fixation, thus facilitating processing.

[0012] This solves the problem that existing devices cannot simultaneously clamp and process multiple sets of bearings, which leads to the need for frequent clamping and fixing of bearings when processing multiple bearings. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-5This utility model provides a technical solution: an automatic clamping bearing processing device, including a base 1, a worm gear 4, a first clamping block 10, a second clamping block 11, and a cylinder 13. Ear plates 2 are welded to both sides of the base 1, and mounting bolts 3 are inserted inside the ear plates 2. Worm gears 4 are distributed on both sides of the base 1, and their surfaces are rotatably connected to the base 1. One end of the worm gear 4 is welded to a connecting rod 8. Two connecting rods 8 are provided, and their ends are respectively welded to the ends of a sliding rod 9. The sliding rod 9 is slidably connected to the ends of the first clamping block 10. A second clamping block 11 is provided between the first clamping blocks 10, and its ends are slidably connected to the sliding rod 9. The first clamping block 10 is fitted onto the outside of the telescopic end of the cylinder 13, and the other end of the cylinder 13 is welded to the surface of the connecting rod 8. Two clamping blocks 11 are provided, and springs 12 are provided between the two clamping blocks. Springs 12 are also provided between the second clamping block 11 and the first clamping block 10. The springs 12 are fitted onto the outside of the slide rod 9. By placing multiple bearings between the first clamping block 10 and the second clamping block 11 respectively, the first clamping block 10 is pushed from both sides by the cylinder 13, so that the first clamping block 10 can slide in relative directions, thereby clamping the bearings between the first clamping block 10 and the second clamping block 11. As the telescopic end of the cylinder 13 continues to extend, the bearings between the two second clamping blocks 11 can be fixed. Thus, the device can fix multiple bearings at the same time during use, which helps to avoid frequent clamping and fixing of bearings when multiple bearings are being processed.

[0022] Example 2:

[0023] The first clamping block 10 has an arc-shaped structure on one side and the second clamping block 11 has arc-shaped grooves on the surface of the first clamping block 10 and the second clamping block 11. The groove surfaces are coated with a rubber coating. The worm wheel 4 is meshed with the worm 6 on one side. The bottom end of the worm 6 is rotatably connected to the inside of the connecting block 5. The two sides of the connecting block 5 are welded to the base 1, and the top end of the worm 6 is welded to the turntable 7. After the first clamping block 10 and the second clamping block 11 clamp and fix the bearing, the turntable 7 is rotated, which drives the worm 6 to rotate. The rotation of the worm 6 drives the worm wheel 4 to rotate, which in turn drives the two connecting rods 8 to rotate. This facilitates the adjustment of the gear fixing angle and the bearing fixing angle, thus facilitating processing.

[0024] Working principle: When the device is in use, multiple bearings are placed between the first clamping block 10 and the second clamping block 11. Then, the cylinder 13 pushes the first clamping block 10 from both sides, allowing the first clamping block 10 to slide in opposite directions. This clamps the bearings between the first clamping block 10 and the second clamping block 11. After the first clamping block 10 and the second clamping block 11 clamp and fix the bearings, the turntable 7 is rotated, which drives the worm gear 6 to rotate. The rotation of the worm gear 6 drives the worm wheel 4 to rotate, which in turn drives the two connecting rods 8 to rotate, thus facilitating the adjustment of the gear fixing angle.
