Description

Technical Field

[0001] This utility model relates to the field of bearing processing, and in particular to laser cladding equipment for machining the outer diameter of bearings. Background Technology

[0002] Laser cladding is a surface modification technology that involves adding cladding material to the surface of a substrate and using a laser beam to fuse it together with a thin layer on the substrate surface to form a metallurgically bonded cladding layer. Laser cladding is an efficient, precise, and economical surface treatment technology that is widely used in industrial manufacturing, aerospace, automotive manufacturing, and other fields.

[0003] Before machining the outer diameter of a bearing, it is necessary to fix the outer diameter of the bearing before laser cladding. Existing equipment requires different fixing components because the inner diameter of the outer diameter of different bearing models is different. As a result, the same fixing component cannot be used for the production of outer diameters of different bearing models, thus limiting its applicability. Utility Model Content

[0004] In view of this, the present invention provides a laser cladding equipment for machining the outer diameter of bearings. The main technical problem to be solved is that the same fixing component cannot be applied to the production of the outer diameter of bearings of different models, thus limiting its applicability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser cladding equipment for machining the outer diameter of bearings, comprising a cladding frame, a rotary motor fixedly connected to the outer wall of the cladding frame, a rotary roller fixedly connected to the output end of the rotary motor, a bidirectional screw movably connected to the inner wall of the rotary roller, a knob fixedly connected to the other end of the bidirectional screw, and a linkage ring threadedly connected to the outer walls of both ends of the bidirectional screw. The outer wall of the linkage ring has multiple perforated grooves, and a linkage post is provided on the inner wall of each of the multiple perforated grooves. The outer wall of the rotary roller has multiple clamping grooves, and a clamping plate is provided inside each of the multiple clamping grooves. A linkage plate is fixedly connected to the inner wall of the clamping plate, and two linkage grooves are provided inside the linkage plate. A linkage post penetrates the linkage groove. The inner wall of the rotary roller has multiple positioning grooves, and a positioning block is fixedly connected to the outer wall of the linkage ring.

[0006] By adopting the above technical solution, multiple clamping plates extend from multiple clamping plate slots and are supported and fixed from the inside of the bearing outer circle. This solution is applicable to bearing outer circles of different models, allowing the bearing outer circle to rotate synchronously with the rotary motor, thus improving applicability.

[0007] As a further description of the above technical solution:

[0008] The other end of the rotating roller is provided with a knob groove, the inner wall of the knob groove is provided with an annular groove, the knob groove is connected to the annular groove, the knob is located inside the knob groove, and a positioning ring is fixedly connected to the outer wall of the bidirectional screw, the positioning ring is located inside the annular groove.

[0009] By adopting the above technical solution, the positioning ring is located in the annular groove, so that the bidirectional screw will not deviate during rotation.

[0010] As a further description of the above technical solution:

[0011] The top of the cladding frame is provided with a movable groove, and a movable screw is movably connected to the inner wall of the movable groove. A movable motor is fixedly connected to the upper end of the outer wall of the cladding frame. The output end of the movable motor is fixedly connected to the other end of the movable screw, and a movable block is threadedly connected to the outer wall of the movable screw.

[0012] By adopting the above technical solution, the operation of the moving motor drives the moving lead screw to rotate, enabling the moving block to move along the moving groove.

[0013] As a further description of the above technical solution:

[0014] A cylinder is fixedly connected to the bottom of the moving block, a laser head base is fixedly connected to the bottom of the cylinder, and a laser head is installed at the bottom of the laser head base.

[0015] By adopting the above technical solution, the cylinder moves synchronously with the moving block. While moving, the cylinder adjusts its stroke so that the laser head can always be located near the outer circle of the bearing.

[0016] As a further description of the above technical solution:

[0017] A baffle is fixedly connected to the outer wall of the rotating roller, and a support leg is fixedly connected to the bottom of the cladding frame. There are two support legs, and each of the two support legs has a fixing hole at its bottom end.

[0018] By adopting the above technical solution, it is easy to fix the entire device and reduce the noise during operation.

[0019] As a further description of the above technical solution:

[0020] Both of the support legs are equipped with shock-absorbing pads at their bottom, and the shock-absorbing pads are made of polyurethane.

[0021] By adopting the above technical solutions, the noise generated during equipment operation can be reduced.

[0022] By employing the above technical solution, the laser cladding equipment for machining the outer diameter of bearings of this utility model has at least the following beneficial effects:

[0023] 1. Compared with existing technologies, this laser cladding equipment for processing the outer diameter of bearings requires supporting and fixing the outer diameter of the bearing. The outer diameter of the bearing is placed around the outside of the rotating roller, and then a knob is turned to drive a bidirectional screw to rotate, causing two linkage rings to move synchronously relative to each other. As the two linkage rings move, the linkage columns inside them move along the linkage grooves inside the linkage plate, causing the linkage plate and clamping plate to extend outwards synchronously, providing internal support from within the outer diameter of the bearing. This allows for adjustment of the clamping range according to different models of bearing outer diameters, fixing different models of bearing outer diameters outside the rotating roller, improving the applicability of the equipment. After the bearing outer diameter is fixed outside the rotating roller, the rotating motor rotates, driving the rotating roller to rotate synchronously, ultimately causing the bearing outer diameter fixed on the rotating roller to rotate synchronously.

[0024] 2. Compared with the existing technology, the laser cladding equipment for processing the outer circle of bearings, after the outer circle of the bearing is fixed, the moving motor drives the moving screw to rotate, so that the moving block, the laser head base and the laser head move synchronously towards the outer circle of the bearing. At the same time, the cylinder moves down, so that the laser head base and the laser head are close to the outer wall of the outer circle of the bearing. After the outer circle of the bearing rotates once, the laser head moves a certain distance to perform the cladding operation on the outer circle of the bearing. Attached Figure Description

A linkage groove 12 is opened inside the linkage plate 11, and there are two linkage grooves 12. A linkage column 8 passes through the linkage groove 12. When the linkage ring 6 moves, multiple linkage columns 8 are provided inside and move along the linkage groove 12 opened inside the linkage plate 11, so that multiple linkage plates 11 drive the clamping plates 10 connected to them to extend outward synchronously, so as to realize the function of supporting from the inside of the outer circle of the bearing. A positioning groove 13 is opened on the inner wall of the rotating roller 3, and there are multiple positioning grooves 13. A positioning block 14 is fixedly connected to the outer wall of the linkage ring 6, and there are multiple positioning blocks 14.

[0036] The other end of the rotating roller 3 is provided with a knob groove 15, and the inner wall of the knob groove 15 is provided with an annular groove 16. The knob groove 15 and the annular groove 16 are connected. The knob 5 is located inside the knob groove 15. The outer wall of the bidirectional screw 4 is fixedly connected with a positioning ring 17, which is located inside the annular groove 16 to position the bidirectional screw 4 so that the bidirectional screw 4 will not deviate when it rotates.

[0037] The top of the cladding frame 1 is provided with a moving groove 18. The inner wall of the moving groove 18 is movably connected to a moving screw 19. The upper end of the outer wall of the cladding frame 1 is fixedly connected to a moving motor 20. The output end of the moving motor 20 is fixedly connected to the other end of the moving screw 19. The outer wall of the moving screw 19 is threadedly connected to a moving block 21. The moving block 21 moves with the movement of the moving motor 20.

The clamping range can be adjusted according to different models of bearing outer circles, so that the outer circles of different models of bearings are fixed on the outside of the rotating roller 3, thus improving the lifting equipment. The bearing outer circle is fixed to the outside of the rotating roller 3. Then the rotating motor 2 rotates and drives the rotating roller 3 to rotate synchronously. Finally, the bearing outer circle fixed on the rotating roller 3 rotates synchronously. After the bearing outer circle is fixed, the moving motor 20 runs and drives the moving screw 19 to rotate, so that the moving block 21, the laser head base 23 and the laser head 24 move synchronously towards the bearing outer circle. At the same time, the cylinder 22 moves down, so that the laser head base 23 and the laser head 24 are close to the outer wall of the bearing outer circle. After the bearing outer circle rotates one revolution, the laser head 24 moves a certain distance to perform the cladding operation on the bearing outer circle.
