Description

Technical Field

[0001] This invention relates to the field of laser repair technology, specifically to a laser repair device for damaged surfaces of gears. Background Technology

[0002] Laser repair, also known as laser surface cladding technology, can repair failed gears and restore their usability. Laser surface cladding repair technology, also known as laser additive manufacturing, uses a high-energy laser as a heat source and metal alloy powder as a welding material. The laser and alloy powder act synchronously on the metal surface to form a dense, uniform, and controllable metallurgical bonding layer, thereby achieving the effect of repairing the surface dimensions of the workpiece and strengthening and extending its service life.

[0003] Existing laser repair equipment for gear damage surfaces directly uses a high-energy laser beam to heat the damaged surface of the gear. It does not preheat the surrounding metal surfaces of the gear before laser repair, resulting in excessively high local temperatures on the damaged surface and a large temperature difference with the surrounding undamaged surfaces. This causes significant differential changes in the metal stress on the damaged surface, leading to a reduction in the overall strength of the gear after laser repair. Consequently, it becomes difficult to meet the high-strength driving requirements of the gear in the future, thus affecting the repair effect of the laser repair equipment.

[0004] Combining the above issues, we find that existing laser repair equipment for gear damaged surfaces has difficulty simultaneously avoiding the problems mentioned above. Even if it can solve these problems, it requires the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a laser repair device for gear damaged surfaces.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a preheating mechanism, the present invention can quickly increase the temperature of the metal around the gear damage surface by inductive eddy current heating before the gear damage surface is laser repaired, thereby preheating the gear damage surface and avoiding excessive temperature difference caused by high-energy laser heat during the laser repair process. This allows the gear damage laser repair device to reduce the stress response of the gear metal and ensure the overall strength of the gear damage surface after repair.

[0016] 2. By setting up a preheating auxiliary component, the present invention enables the heating coil to move with the laser repair head, and ensures that the heating coil is always in front of the laser repair head in the direction of travel. This ensures that the heating coil can preheat the area to be repaired in advance, regardless of the direction in which the laser repair head moves to perform laser repair on the damaged surface of the gear. Furthermore, the normal power supply of the heating coil is not affected when the heating coil rotates to adjust its direction, thereby further ensuring the reliability of preheating for laser repair of the damaged surface of the gear.

This increases the efficiency of gear laser repair and the ease of position adjustment. Attached Figure Description

Detailed Implementation

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

[0020] Example 1: Please refer to Figures 1-5This invention provides a technical solution: a laser repair device for damaged gear surfaces, including a base plate 1, a damaged gear 2 disposed above the base plate 1, a preheating mechanism 3 disposed above the base plate 1, the preheating mechanism 3 including a four-jaw chuck 301, the bottom surface of the four-jaw chuck 301 being fixedly connected to the upper surface of the base plate 1, the damaged gear 2 being engaged inside the four-jaw chuck 301, a laser repair head 302 disposed above the damaged gear 2, a sliding seat 303 being fixedly connected to the upper surface of the laser repair head 302, a fixed plate 304 being fixedly connected to the outer surface of the laser repair head 302, a rotating plate 305 being slidably connected inside the fixed plate 304, a connecting frame 306 being fixedly connected to the bottom surface of the rotating plate 305, a positioning plate 307 being fixedly connected to the bottom surface of the connecting frame 306, a heating coil 308 being fixedly connected to the inner wall of the positioning plate 307, an electronic oscillator 309 being fixedly connected to the upper surface of the positioning plate 307, and the electronic oscillator 309 being electrically connected to the heating coil 308 via a wire.

[0021] The specific implementation method of this embodiment is as follows: First, the damaged surface of the damaged gear 2 is clamped and fixed by the four-jaw chuck 301 with the damaged surface facing upward. Then, the heating coil 308 is energized and the electronic oscillator 309 is oscillated at high frequency by switching between positive and negative poles. This generates inductive eddy currents around the heating coil 308, thereby increasing the movement speed of electrons inside the damaged surface of the damaged gear 2 and causing it to quickly generate high temperature. Then, the laser repair head 302 is moved to the position of the damaged gear 2 that needs to be repaired. The damaged surface is repaired by cladding with metal alloy powder using a high-energy laser beam. By using the method of rapid preheating of the damaged surface of the damaged gear 2 by inductive eddy currents, the temperature difference between the damaged surface of the gear and other positions can be shortened during the laser repair process. This makes it less likely that the high temperature generated when the damaged surface of the gear is heated by the high-energy laser beam will cause a strong stress reaction on the gear as a whole, thereby ensuring the overall strength of the gear after the damaged surface is repaired.

[0022] Example 2: Please refer to Figure 3 and Figure 4 The present invention provides a technical solution: a laser repair device for gear damage surfaces. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A preheating auxiliary component 4 is provided above the preheating mechanism 3.

[0023] As a further definition of the preheating auxiliary component 4 of the present invention, the preheating auxiliary component 4 includes a gear disk 401, the inner wall of the gear disk 401 is fixedly connected to the outer surface of the rotating disk 305, a small servo motor 402 is arranged above the fixed disk 304, a connecting gear 403 is fixedly connected to the output end of the small servo motor 402, the outer surface of the connecting gear 403 meshes with the outer surface of the gear disk 401, two first conductive slip rings 404 are fixedly connected to the inner top wall of the fixed disk 304, and two second conductive slip rings 405 are fixedly connected to the inner bottom wall of the rotating disk 305. The bottom surfaces of the two first conductive slip rings 404 are respectively in contact with the upper surfaces of the two second conductive slip rings 405, and a first connecting line 406 is fixedly connected to the bottom surface of each of the two second conductive slip rings 405. The other end of each of the two first connecting lines 406 is electrically connected to the electronic oscillator 309.

[0024] A stabilizing base 407 is fixedly connected to the outer surface of the small servo motor 402. The bottom surface of the stabilizing base 407 is fixedly connected to the upper surface of the fixed plate 304. The stabilizing base 407 can stabilize the position of the small servo motor 402, ensure that the small servo motor 402 can operate normally, and improve the reliability of the small servo motor 402. A stabilizing bracket 408 is rotatably connected to the outer surface of the output end of the small servo motor 402. One side of the stabilizing bracket 408 is fixedly connected to the outer surface of the fixed plate 304. The stabilizing bracket 408 can increase the meshing tightness between the connecting gear 403 and the gear plate 401, prevent the connecting gear 403 and the gear plate 401 from shifting, and ensure the reliability of the engagement between the connecting gear 403 and the gear plate 401. A partition ring 409 is fixedly connected to the inner bottom wall of the rotating disk 305. The partition ring 409 is disposed between the two second conductive slip rings 405. The upper surface of the partition ring 409 is in contact with the inner top wall of the fixed disk 304. The partition ring 409 can form a partition between the two first conductive slip rings 404 and the two second conductive slip rings 405 without affecting the rotation of the rotating disk 305, preventing short circuit when positive and negative currents pass through the first conductive slip rings 404 and the second conductive slip rings 405, thus improving the safety of the first conductive slip rings 404 and the second conductive slip rings 405. The upper surfaces of the two first conductive slip rings 404 are fixedly connected with second connecting lines 410. The top ends of the two second connecting lines 410 extend to the top of the fixed disk 304. The two first conductive slip rings 404 can be smoothly connected to the positive and negative terminals of the external power supply through the two second connecting lines 410, ensuring the normal operation of the external power supply.

[0025] The specific implementation of this embodiment is as follows: When the heating coil 308 needs to generate inductive eddy currents to preheat the damaged surface of the damaged gear 2, external current can be sent into the electronic oscillator 309 through the second connecting line 410, the first conductive slip ring 404, the second conductive slip ring 405, and the first connecting line 406. Then, the current is sent to the heating coil 308 for use through the electronic oscillator 309. When the laser repair head 302 moves in different directions to perform laser repair on the damaged surface of different positions on the damaged gear 2, the power provided by the small servo motor 402, in conjunction with the stabilizing base 407, can drive the gear disk 401 and the rotating disk 305 within the fixed disk 304 using the connecting gear 403. The rotating part rotates, thereby driving the positioning disk 307 and heating coil 308 to rotate via the connecting frame 306. This ensures that the heating coil 308 is always positioned in front of the laser repair head 302 in the direction of travel, guaranteeing that the heating coil 308 can preheat the area to be repaired regardless of the direction in which the laser repair head 302 moves to perform laser repair on the damaged gear surface. Furthermore, during the rotation of the rotating disk 305, the second conductive slip ring 405 also rotates. The contact between the second conductive slip ring 405 and the first conductive slip ring 404 ensures that the current transmission is not affected by the rotation of the rotating disk 305, guaranteeing that the heating coil 308 can always receive current.

[0026] Example 3: Please refer to Figure 6 and Figure 7 The present invention provides a technical solution: a laser repair device for gear damage surfaces. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A movable component 5 is provided on the outside of the base plate 1.

[0027] As a further definition of the movable component 5 of the present invention, the movable component 5 includes two support frames 501, both of which are disposed outside the base plate 1. A first screw 502 is rotatably connected inside each of the two support frames 501. A first rotary motor 503 is fixedly connected to the left side of one of the support frames 501. A connecting rod 504 is fixedly connected to the output end of the first rotary motor 503. Two first bevel gears 505 are fixedly connected to the outer surface of the connecting rod 504. A second bevel gear 506 is fixedly connected to the top of each of the two first screws 502. The two second bevel gears 506 mesh with the two first bevel gears 505 respectively. A movable frame 507 is slidably connected inside both support frames 501. A sliding seat 303 is slidably connected inside the movable frame 507. Both first screws 502 are threadedly connected to the movable frame 507. A second rotary motor 508 is fixedly connected to the inner wall of the movable frame 507. The output end of the second rotary motor 508 is fixedly connected to the second screw 509, which is rotatably connected inside the movable frame 507. The second screw 509 is threadedly connected to the sliding seat 303. The outer surfaces of the two support frames 501 are slidably connected to the positioning frames 510. The opposite sides of the two positioning frames 510 are fixedly connected to the two sides of the base plate 1. The interior of the two positioning frames 510 is rotatably connected to the third screw 511, which is threadedly connected to the two support frames 501. The left side of one of the positioning frames 510 is fixedly connected to the third rotary motor 512. The output end of the third rotary motor 512 is fixedly connected to the transmission rod 513. The outer surface of the transmission rod 513 is fixedly connected to two third bevel gears 514. One end of each of the two third screws 511 is fixedly connected to a fourth bevel gear 515, which meshes with the two third bevel gears 514.

[0028] Two limiting brackets 516 are rotatably connected to the outer surface of the connecting rod 504. The bottom surfaces of the two limiting brackets 516 are fixedly connected to the upper surfaces of the two support brackets 501 respectively. The limiting brackets 516 can restrict the position of the connecting rod 504, thereby ensuring that the first bevel gear 505 and the second bevel gear 506 can always maintain meshing, and improving the fit between the first bevel gear 505 and the second bevel gear 506. An auxiliary frame 517 is rotatably connected to the outer surface of the transmission rod 513. The front sides of the two positioning frames 510 are fixedly connected to the back side of the auxiliary frame 517. The auxiliary frame 517 can increase the rotational stability of the transmission rod 513 without affecting its rotation, thus ensuring the stability and reliability of the power transmission process of the transmission rod 513.

[0029] The specific implementation of this embodiment is as follows: The power provided by the first rotating motor 503, in conjunction with the support frame 501, drives the connecting rod 504 to rotate. Then, the first bevel gear 505 and the second bevel gear 506 drive the two first screws 502 to rotate synchronously, allowing the moving frame 507, in conjunction with the sliding seat 303, to move the laser repair head 302 up and down. Next, the power provided by the second rotating motor 508, in conjunction with the moving frame 507, drives the second screw 509 to rotate, allowing the sliding seat 303 and the laser repair head 302 to move left and right. Finally, the power provided by the third rotating motor 512, in conjunction with the positioning frame 510, drives the transmission rod 513 to rotate. Then, the third bevel gear 514, in conjunction with the fourth bevel gear 515, drives the two third screws 511 to rotate synchronously, allowing the support frame 501 to move the sliding seat 303 and the laser repair head 302 back and forth via the moving frame 507. This allows the laser repair head 302 to move in any direction, facilitating its movement to different damaged positions on the damaged gear 2 for laser repair.

[0030] This application also provides a laser repair method based on the above-mentioned repair equipment: First, the damaged surface of the damaged gear 2 is held and fixed by the four-jaw chuck 301 with the damaged surface facing upwards. Then, the heating coil 308 is energized and the electronic oscillator 309 is oscillating at high frequency by switching between positive and negative poles. This generates inductive eddy currents around the heating coil 308, which increases the movement speed of electrons inside the damaged surface of the damaged gear 2, causing it to quickly generate high temperature. Then, the laser repair head 302 is moved to the position of the damaged gear 2 that needs to be repaired. The damaged surface is repaired by cladding with metal alloy powder using a high-energy laser beam. By using the method of rapid preheating of the damaged surface of the damaged gear 2 by inductive eddy currents, the temperature difference between the damaged surface of the gear and other positions can be shortened during the laser repair process. This makes it less likely that the high temperature generated when the damaged surface of the gear is heated by the high-energy laser beam will cause a strong stress reaction on the gear as a whole, thus ensuring the overall strength of the gear after the damaged surface is repaired. Then, when the heating coil 308 needs to generate inductive eddy current to preheat the damaged surface of the damaged gear 2, external current can be sent into the electronic oscillator 309 through the second connecting line 410, the first conductive slip ring 404, the second conductive slip ring 405 and the first connecting line 406, and then sent to the heating coil 308 for use through the electronic oscillator 309. Furthermore, when the laser repair head 302 moves in different directions to perform laser repair on the damaged surfaces of different positions on the damaged gear 2, the power provided by the small servo motor 402, in conjunction with the stabilizing base 407, enables the connecting gear 403 to drive the gear disk 401 and the rotating disk 305 to rotate inside the fixed disk 304. This allows the connecting frame 306 to drive the positioning disk 307 and the heating coil 308 to rotate, ensuring that the heating coil 308 is always in front of the laser repair head 302 in the direction of travel. This ensures that no matter which direction the laser repair head 302 moves to perform laser repair on the damaged surface of the gear, the heating coil 308 can preheat the area to be repaired in advance. Meanwhile, as the rotating disk 305 rotates, it can also drive the second conductive slip ring 405 to rotate. At this time, by utilizing the contact between the second conductive slip ring 405 and the first conductive slip ring 404, it can be ensured that the current transmission is not affected by the rotation of the rotating disk 305, and that the heating coil 308 can always receive current. Furthermore, the power provided by the first rotating motor 503, in conjunction with the support frame 501, can drive the connecting rod 504 to rotate, thereby using the first bevel gear 505 and the second bevel gear 506 to drive the two first screws 502 to rotate synchronously, so that the moving frame 507, in conjunction with the sliding seat 303, can drive the laser repair head 302 to move up and down. Then, the power provided by the second rotating motor 508, in conjunction with the moving frame 507, drives the second screw 509 to rotate, allowing the sliding seat 303 and the laser repair head 302 to move left and right. Finally, the power provided by the third rotating motor 512, in conjunction with the positioning frame 510, drives the transmission rod 513 to rotate. In turn, the third bevel gear 514, in conjunction with the fourth bevel gear 515, drives the two third screws 511 to rotate synchronously. This allows the support frame 501 to move the sliding seat 303 and the laser repair head 302 back and forth via the moving frame 507, enabling the laser repair head 302 to move in any direction. This facilitates the laser repair head 302 to move to different damaged positions on the damaged gear 2 for laser repair work.
