Description

Technical Field

[0001] This utility model relates to the field of cladding technology, and in particular to a self-cleaning laser cladding device. Background Technology

[0002] Laser cladding technology refers to a process in which a selected coating material is placed on the surface of a substrate using different filler methods. The material is then irradiated with a laser to melt the coating material and a thin layer on the substrate surface simultaneously. After rapid solidification, a surface coating with extremely low dilution and metallurgical bonding with the substrate material is formed, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the substrate material surface.

[0003] In the prior art, such as Chinese Patent No. CN220703798U, there is a laser cladding equipment. This laser cladding equipment includes a workpiece table, a feeding assembly, a guiding assembly, a laser assembly, a smoothing assembly, and a controller. The workpiece table has a workpiece holding area for accommodating the tube array to be coated. The feeding assembly includes a feeding support and a storage container. The feeding support has a crossbeam located directly above the workpiece holding area. The storage container has multiple discharge ports, which are spaced apart along the length of the crossbeam and located directly above multiple tubes of the tube array to be coated. The guiding assembly is connected between the feeding assembly and the workpiece table to move the feeding assembly along the tube axis of the tube array to be coated. The laser assembly is located on the feeding support. This laser cladding equipment can improve the operating efficiency of the laser cladding process.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: although the support columns can facilitate the collection of cladding material powder that falls onto the workpiece table after smoothing, thus saving costs, it requires workers to collect the cladding material powder that falls onto the worktable periodically. When workers clean the cladding material powder on the worktable, the laser cladding operation on the tube array needs to be paused, resulting in low efficiency of tube array laser cladding. Furthermore, it can only laser clad half of the tube array at a time. When laser cladding is needed on the other half of the tube array, workers need to manually flip the tube array, increasing the labor intensity of the workers. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology. Although the support column can facilitate the collection of cladding material powder that falls onto the workpiece table after smoothing, thus saving costs, it requires workers to collect the cladding material powder that falls onto the worktable regularly. When workers clean the cladding material powder on the worktable, the laser cladding operation on the tube array needs to be paused, resulting in low efficiency of tube array laser cladding. In addition, it can only laser clad half of the tube array at a time. When laser cladding is needed on the other half of the tube array, workers need to manually flip the tube array, which increases the labor intensity of workers.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a self-cleaning laser cladding device, comprising: a frame, and further comprising:

[0007] A guide rail is fixedly connected to the top of the frame. A lead screw is rotatably connected to the opposite side of the inner wall of the guide rail. An L-shaped plate is threaded onto the outer surface of the lead screw. A motor is fixedly connected to one side of the guide rail. The output end of the motor is fixedly connected to one end of the lead screw. Multiple laser cladding equipment bodies are fixedly connected at equal intervals to the top of the L-shaped plate. A laser nozzle is fixedly connected to the bottom of the laser cladding equipment body. A partition is provided on the inner wall of the frame. An L-shaped block is fixedly connected to the side of the L-shaped plate near the bottom. A brush plate is fixedly connected to the bottom of the L-shaped block.

[0008] Preferably, the top of the partition is provided with multiple strip grooves at equal intervals, and the outer surface of the L-shaped plate is slidably connected to the inside of the guide rail.

[0009] Preferably, the top of the frame is symmetrically fixedly connected to two fixing plates, and one side of each fixing plate is rotatably connected to a rotating rod.

[0010] Preferably, a second motor is fixedly connected to one side of one of the fixed plates, and the output end of the second motor is fixedly connected to one end of one of the rotating rods.

[0011] Preferably, a U-shaped plate is fixedly connected to the other end of the rotating rod, and two screws are symmetrically threaded to the top of the U-shaped plate.

[0012] Preferably, a fixing block two is fixedly connected to the other side of the L-shaped plate near the top, an electric telescopic rod two is fixedly connected to the bottom of the fixing block two, a connecting plate is fixedly connected to one end of the electric telescopic rod two, and multiple arc-shaped flat plates are fixedly connected at equal intervals to the bottom of the connecting plate.

[0013] Preferably, a bottom frame is fixedly connected to the bottom of the square frame, the bottom frame is connected to the square frame, a collection frame is fixedly connected to one side of the bottom frame, and a handle is fixedly connected to one side of the collection frame.

Both electric telescopic rods are fixedly connected to the partition, and the outer surface of the partition is slidably connected to the inside of the frame.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model, by moving the L-shaped plate, can drive the L-shaped block and brush plate to one side, sweeping the coating material powder on the partition, causing the coating material powder to fall into the bottom frame through the strip groove and be collected by the collection frame. In this way, when laser coating is applied to the tube, the coating material powder on the partition can be automatically cleaned without stopping the laser cladding operation of the tube, thereby improving the efficiency of laser cladding of the tube.

[0017] 2. This utility model controls the L-shaped plate, the main body of the laser cladding equipment, and the laser nozzle to move away from the top of the pipe. Then, the controller starts the electric telescopic rod to retract, causing the partition to move downward and maintain a certain distance between the partition and the pipe. Next, the controller starts the motor, causing its output shaft to drive one set of rotating rods and U-shaped plates to rotate. With the cooperation of the other set of rotating rods and U-shaped plates, the pipe can be rotated 180 degrees. This eliminates the need for workers to manually rotate the pipe, thus reducing the labor intensity of the workers. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-4 As shown, this utility model provides a self-cleaning laser cladding device, including: a square frame 1, and a guide rail 2, which is fixedly connected to the top of the square frame 1. A lead screw 201 is rotatably connected to the opposite side of the inner wall of the guide rail 2. An L-shaped plate 202 is threadedly connected to the outer surface of the lead screw 201. A motor 203 is fixedly connected to one side of the guide rail 2. The output end of the motor 203 is fixedly connected to one end of the lead screw 201. Multiple laser cladding device bodies 204 are fixedly connected at equal intervals to the top of the L-shaped plate 202. A laser nozzle 205 is fixedly connected to the bottom of the laser cladding device body 204. A partition 101 is provided on the inner wall of the square frame 1. An L-shaped block 105 is fixedly connected to the side of the L-shaped plate 202 near the bottom. A brush plate 102 is fixedly connected to the bottom of the L-shaped block 105.

[0027] Furthermore, such as Figure 1-4 As shown, the top of the partition 101 is provided with multiple strip grooves at equal intervals. The outer surface of the L-shaped plate 202 is slidably connected to the inside of the guide rail 2. The strip grooves facilitate the dropping of coating material powder to the bottom. The guide rail 2 provides a certain limiting and guiding function for the L-shaped plate 202, allowing the L-shaped plate 202 to slide to one side along the inside of the guide rail 2.

[0028] Furthermore, such as Figure 1-4As shown, two fixed plates 4 are symmetrically fixed to the top of the box 1. A rotating rod 401 is rotatably connected to one side of the fixed plate 4. The controller controls the motor 402 to start, so that its output shaft drives one of the rotating rods 401 to rotate.

[0029] Furthermore, such as Figure 1-4 As shown, a second motor 402 is fixedly connected to one side of one of the fixed plates 4, and the output end of the second motor 402 is fixedly connected to one end of one of the rotating rods 401.

[0030] Furthermore, such as Figure 1-4 As shown, a U-shaped plate 403 is fixedly connected to the other end of the rotating rod 401. Two screws 404 are symmetrically threaded to the top of the U-shaped plate 403. By turning the screws 404 by hand, the tube can be turned upwards to release the squeezing state on the tube. At this time, the tube can be pulled out from the inside of the two U-shaped plates 403. Then, the tube to be laser clad is inserted into the two U-shaped plates 403, and the tube is pressed and fixed by turning the screws 404 in the opposite direction.

[0031] Furthermore, such as Figure 1-4 As shown, a fixing block 202 is fixedly connected to the other side near the top of the L-shaped plate 202. An electric telescopic rod 201 is fixedly connected to the bottom of the fixing block 202. A connecting plate 302 is fixedly connected to one end of the electric telescopic rod 201. Multiple arc-shaped smoothing plates 303 are fixedly connected at equal intervals to the bottom of the connecting plate 302. The electric telescopic rod 201 is started by the controller, so that it extends or retracts, which drives the connecting plate 302 and the arc-shaped smoothing plates 303 to move downward or upward. The distance between the arc-shaped smoothing plates 303 and the outer surface of the pipe can be controlled, thereby controlling the thickness of the coating material powder on the surface of the pipe and making the coating material powder on the surface of the pipe more uniform.

[0032] Furthermore, such as Figure 1-4 As shown, a bottom frame 103 is fixedly connected to the bottom of the box 1. The bottom frame 103 is connected to the box 1. A collection frame 104 is fixedly connected to one side of the bottom frame 103. A handle is fixedly connected to one side of the collection frame 104. The bottom frame 103 facilitates the coating material powder to fall into the collection frame 104. The collection frame 104 can be removed using the handle to recycle the collected coating material powder.

[0033] Furthermore, such as Figure 1-4As shown, two diagonal inner walls near the bottom of the frame 1 are fixedly connected to fixing blocks 106. The top of the fixing blocks 106 is fixedly connected to electric telescopic rods 107. Both electric telescopic rods are fixedly connected to the partition 101. The outer surface of the partition 101 is slidably connected to the inside of the frame 1. The controller controls the electric telescopic rods 107 to retract, causing the partition 101 to move downward, so that the partition 101 maintains a certain distance from the pipe.

[0034] Working principle: During use, the controller starts the motor 203, causing its output shaft to drive the lead screw 201 to rotate. Then, under the action of the threaded connection between the lead screw 201 and the L-shaped plate 202, and with the cooperation of the guide rail 2 in limiting and guiding the L-shaped plate 202, the L-shaped plate 202 can move to one side along the outer surface of the lead screw 201. Simultaneously, the controller starts the main body 204 of the laser cladding equipment, causing its laser nozzle 205 to perform laser cladding on the upper half of the pipe. At the same time, the external spraying equipment sprays coating material powder onto the surface of the pipe. Simultaneously, the controller starts the electric telescopic rod 301, causing it to extend or retract, which drives the connecting plate. The curved smoothing plate 302 and the curved smoothing plate 303 move downwards or upwards, controlling the distance between the curved smoothing plate 303 and the outer surface of the tube. This controls the thickness of the coating material powder on the tube surface, making the coating material powder more uniform. Some of the coating material powder will fall onto the partition plate 101. Simultaneously, the movement of the L-shaped plate 202 can drive the L-shaped block 105 and the brush plate 102 to one side, sweeping the coating material powder on the partition plate 101. This causes the coating material powder to fall through the strip groove onto the bottom frame 103 and be collected by the collection frame 104. In this way, when laser coating is applied to the tube, the coating material powder on the partition plate 101 can be automatically applied. Material powder is cleaned without interrupting the laser cladding operation on the pipe, thus improving the efficiency of the laser cladding. When laser cladding is needed on the other half of the pipe, the L-shaped plate 202, the main body of the laser cladding equipment 204, and the laser nozzle 205 are moved away from above the pipe by controlling the L-shaped plate 202. Then, the controller starts the electric telescopic rod 107 to retract, causing the partition 101 to move downwards, maintaining a certain distance between the partition 101 and the pipe. Next, the controller starts the motor 402, causing its output shaft to drive one set of rotating rods 401 and U-shaped plates 403 to rotate. With the cooperation of the other set of rotating rods 401 and U-shaped plates 403, The tube can be rotated 180 degrees and kept in a fixed state by the pressure of the screw 404. The above operation is repeated to perform laser cladding on the other half of the tube. This eliminates the need for workers to manually rotate the tube, thus reducing their labor intensity. When the laser cladding on the tube surface is complete, the screw 404 can be turned upwards by hand to release the pressure on the tube. At this time, the tube can be pulled out from inside the two U-shaped plates 403. Then, the tube to be laser clad is inserted into the two U-shaped plates 403, and the tube is tightened and fixed by rotating the screw 404 in the opposite direction.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
