Description

Technical Field

[0001] The utility model relates to the technical field of laser repair, in particular to a laser additive remanufacturing device for damaged parts. Background Art

[0002] In modern industrial production, parts of various mechanical equipment may be damaged due to wear, corrosion, fatigue and other reasons during long-term use. Traditional parts repair methods often have some limitations, such as poor repair effect, the performance of the repaired parts is difficult to reach the level of the original parts, the repair process is complicated and the cost is high. With the continuous advancement of science and technology, laser technology is more and more widely used in the industrial field. Laser has the characteristics of high energy density, high precision, and high controllability, which can realize the precise processing and treatment of materials. Against this background, the laser additive remanufacturing device for damaged parts came into being. This device uses a laser beam to melt specific materials (such as metal powder, alloy wire, etc.) and deposit them on the surface of the damaged parts. By stacking layers, it can achieve precise repair of the damaged parts. It can restore the size and performance of the parts without changing the overall structure of the parts, and can even strengthen and improve the parts to improve their service life and reliability.

[0003] However, the existing laser additive remanufacturing device for damaged parts can only adjust the laser additive processing head in one direction, which cannot meet the needs of multi-angle and multi-directional adjustment. It may not be able to accurately focus the laser beam on the damaged part, resulting in poor repair effect. The adaptability of the device when dealing with complex parts is greatly reduced, which consumes a lot of time and energy and increases production costs. Frequent adjustments may also increase the workload of operators and the probability of errors. Utility Model Content

Universal wheels 7 are provided at the bottoms of the four support legs 6. A repair platform 8 is provided on the top of the workbench 1.

[0024] In this embodiment, when it is necessary to adjust the laser additive processing head 4 in multiple directions, the adjustment mechanism 2 is provided to first adjust the depth direction of the laser additive processing head 4, start the first motor 204, and the first motor 204 works to rotate the threaded rod 205, thereby driving the crossbeam 206 to slide in the first slide groove 203. When it reaches a suitable position, the first motor is turned off, and then the lateral direction of the laser additive processing head 4 is adjusted, and the second motor 208 is started. The second motor 208 works to rotate the gear 209, thereby driving the toothed slide 211 meshed with the gear 209 to slide laterally in the second slide groove 210, thereby The slider 213 fixedly connected to the toothed slide 211 is driven to slide in the third slide groove 212. Since the inner sides of the two sliders 213 are fixedly connected by the connecting rod 214, the telescopic rod 215 installed at the bottom of the slider is driven to move together, thereby driving the clamping mechanism 3 and the laser additive processing head 4 to move laterally. When reaching the appropriate position, the second motor 208 can be turned off, thereby achieving the effect of multi-directional adjustment of the laser additive processing head 4, thereby accurately focusing the laser beam on the damaged part, improving the adaptability of the device in dealing with complex parts, reducing production costs, and alleviating the operator's workload and the probability of error.

[0025] Example 2: Figures 1-4 As shown, the clamping mechanism 3 includes a fixed plate 301, a sliding rod 302 is fixedly installed on the inner side of the two fixed plates 301, and a clamping block 303 is symmetrically slidably installed on the outer wall of the two sliding rods 302. The two clamping blocks 303 are fixedly installed with a corresponding threaded fixing rod 304 on one side close to the corresponding fixed plate 301, and the corresponding threaded fixing rod 304 is threaded through the corresponding fixed plate 301.

[0026] In this embodiment, when it is necessary to firmly clamp the laser additive processing head 4, first place the laser additive processing head 4 in a suitable position of the clamping mechanism 3, and then rotate the two threaded fixing rods 304. Since the threaded fixing rods 304 are fixedly installed on the clamping blocks 303, the two clamping blocks 303 slide on the slide rod 302, so that the two clamping blocks 303 firmly clamp the laser additive processing head 4 in the middle of the two clamping blocks 303 to prevent it from moving or shaking during the processing process. This ensures that the laser beam can accurately irradiate the damaged part and ensures the accuracy and quality of the repair.

[0027] The working principle of this embodiment: when in use, first move the device to the appropriate position through the universal wheel 7, and then place the damaged parts inside the repair platform 8. Then the laser additive processing head 4 needs to be firmly clamped. First, place the laser additive processing head 4 in the appropriate position of the clamping mechanism 3, and then rotate the two threaded fixing rods 304. Since the threaded fixing rods 304 are fixedly installed on the clamping blocks 303, the two clamping blocks 303 slide on the slide rod 302, so that the two clamping blocks 303 firmly hold the laser additive processing head 4 in the middle of the two clamping blocks 303 to prevent it from moving or shaking during the processing process. This can ensure that the laser beam can accurately irradiate the damaged part and ensure the accuracy and quality of the repair. When it is necessary to adjust the laser additive processing head 4 in multiple directions, the adjustment mechanism 2 is controlled by the control panel 5. First, the depth direction of the laser additive processing head 4 is adjusted, and the first motor 204 is started. The first motor 204 works to rotate the threaded rod 205, thereby driving the crossbeam 206 to slide in the first slide groove 203. When it reaches a suitable position, the first motor is turned off. Then, the horizontal direction of the laser additive processing head 4 is adjusted, and the second motor 208 is started. The second motor 208 works to rotate the gear 209, thereby driving the toothed slide 211 meshed with the gear 209 to slide horizontally in the second slide groove 210, thereby The slider 213 fixedly connected to the toothed slide 211 is driven to slide in the third slide groove 212. Since the inner sides of the two sliders 213 are fixedly connected by the connecting rod 214, the telescopic rod 215 installed at the bottom of the slider is driven to move together, thereby driving the clamping mechanism 3 and the laser additive processing head 4 to move laterally. When reaching the appropriate position, the second motor 208 can be turned off, thereby achieving the effect of multi-directional adjustment of the laser additive processing head 4, thereby accurately focusing the laser beam on the damaged part, improving the adaptability of the device in dealing with complex parts, reducing production costs, and alleviating the operator's workload and the probability of error.
