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.

[0023] Please see Figure 1-4This utility model provides a technical solution: a laser cladding device for motor processing, including a worktable 11, a fixed frame 7 fixedly connected to the top side of the worktable 11, a frame 4 fixedly connected to the top of the worktable 11, an axial drive mechanism 1 set at the bottom of the frame 4, a laser welding head 3 set on the axial drive mechanism 1, and an alloy powder conveying pipe 2 connected to the laser welding head 3. This axial drive mechanism 1 includes Y, Z, and X axis drives, and the drive equipment can be ball screws, electric cylinders, etc., mainly used to adjust the processing position of the laser welding head 3. One end of the alloy powder conveying pipe 2 is connected to an alloy powder storage pipe, and the alloy powder conveying pipe 2 is driven by a powder pump, automatically feeding alloy powder during the welding process. The laser welding head 3 is driven by a laser generator. Some of the technology is existing, so it will not be described in detail here. The inner side of the fixing frame 7 is rotatably connected to a rotating arm 5. Two rotating arms 5 are provided. One rotating arm 5 is rotatably connected to a tube 8 on its inner side, and the other rotating arm 5 is fixedly connected to a first electric cylinder 16 on its outer wall. One end of the first electric cylinder 16 is rotatably connected to a clamping plate 17. The clamping plate 17 and the tube 8 clamp the motor shaft 18. A motor is installed inside the rotating arm 5 of this structure to drive the tube 8 to rotate automatically, facilitating the automatic rotation of the motor shaft 18 and improving the cleaning and cladding effects. A turntable is embedded inside the clamping plate 17, so that clamping one side of the motor shaft 18 will not affect its rotation. The fixing frame 7 and the rotating arms 5 are symmetrically distributed about the bisector of the worktable 11. A first motor 6 is installed on one side, and a motor shaft 18 is clamped inside the rotating arm 5. A laser welding head 3 is installed on the top of the motor shaft 18, and a reciprocating ball screw 14 is installed at the bottom of the motor shaft 18. The reciprocating ball screw 14 is composed of a fixed seat, a threaded rod, a motor, and a screw slide. The top of the screw slide of the reciprocating ball screw 14 is fixedly connected to the mounting bracket 19. There are two mounting brackets 19. A first cleaning component 9 and a second cleaning component 20 are respectively installed inside the two mounting brackets 19. The first cleaning component 9 and the second cleaning component 20 have the same structure. The second cleaning component 20 includes a splicing block 201 that is rotatably connected to the mounting bracket 19. A second motor 10 is installed on one side of the mounting bracket 19. The shaft of the second motor 10 is connected to the shaft at the lower end of the splicing block 201 via a coupling. This structure allows the second motor 10 to drive the splicing block 201 of the second cleaning component 20 and the first cleaning component 9 to rotate and open or close. A second electric cylinder 205 is fixed to the inner wall of the splicing block 201 via a bracket. One end of the second electric cylinder 205 is fixedly connected to a fixed base 204. This structure allows the second electric cylinder 205 to push the non-woven fabric block 203 on the inner side of the fixed base 204 to adhere to the surface of the motor shaft 18, thereby applying pressure to the motor shaft 18, ensuring a good fit and improving the cleaning effect. The splicing block 201 has an arc-shaped structure, and the fixed base 204 is slidably connected to the inner side of the splicing block 201. The non-woven fabric block 203 is adhered to the inner side of the fixed base 204.The splicing block 201 has an embedded diversion pipe 202, which has an arc-shaped structure. Multiple nozzles are evenly spaced in an arc shape along the inner wall of the diversion pipe 202. This structure allows the cleaning solvent, such as an alkaline degreaser, to be evenly sprayed onto the surface of the motor shaft 18 through the diversion pipe 202. The lower end of the diversion pipe 202 is connected to a connecting pipe 15, which is equipped with a delivery pump 13 and a solenoid valve. This structure allows for automatic delivery of the cleaning solvent via the delivery pump 13 and the connecting pipe 15. One end of the connecting pipe 15 is connected to a solvent storage tank 12. The non-woven fabric block 203 of this device is connected to the fixing base 204 via Velcro for easy replacement. The device is controlled by a PLC during use.

[0024] Working principle: When using this motor to process the laser cladding device, firstly, the motor shaft 18 is placed between the insert 8 and the clamping plate 17, so that the first electric cylinder 16 pushes the clamping plate 17 to clamp the motor shaft 18 between the insert 8 and the clamping plate 17. Then, according to the position on the motor shaft 18 that needs to be clad, the positions of the first cleaning component 9 and the second cleaning component 20 are adjusted. During adjustment, the reciprocating ball screw 14 drives the mounting bracket 19 and the first cleaning component 9 and the second cleaning component 20 and other accessories to move laterally to the appropriate position. Then, the second motor 10 drives the splicing block 201 of the first cleaning component 9 and the second cleaning component 20 to rotate and close, so that the two splicing blocks 201 are spliced ​​together. The non-woven fabric block 203, which is wrapped in a ring structure on the outer wall of the motor shaft 18, adheres to the outer wall of the motor shaft 18. Then, the delivery pump 13 is started, so that the solvent inside the solvent storage tank 12 is sprayed from the diversion pipe 202 onto the surface of the motor shaft 18. At the same time, the insert 8, the motor shaft 18 and the clamping plate 17 rotate to make the motor shaft 18 and the non-woven fabric block 203 make uniform friction contact. During the cleaning process, the lateral movement of the first cleaning component 9 and the second cleaning component 20 can make the non-woven fabric block 203 wipe the solvent on the motor shaft 18 evenly, so that the motor shaft 18 dries quickly, thereby ensuring the cleanliness of the surface of the motor shaft 18 during the cladding.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
