[0029] The utility model provides a spot welding device for motor rotors as shown in Figure 1 and includes a fixing mechanism 1, and also includes:

[0030] A clamping mechanism 2 is arranged on the top of the fixing mechanism 1 and is used for clamping and fixing the rotor to be welded;

[0031] A welding mechanism 3 is arranged on one side of the fixing mechanism 1 and is used for welding the rotor.

[0032] In order to conveniently clamp and fix rotors of different sizes, as shown in Figure 2 and Figure 4 , the clamping mechanism 2 includes a placing plate 201 and a rotating shaft 206. The placing plate 201 is arranged on the top of the horizontal part of the fixing mechanism 1. Four electric push rods 203 are arranged on the inner wall of the placing plate 201. Clamping plates 204 are fixedly installed at the output ends of the four electric push rods 203. A driven gear ring 205 is fixedly installed at the bottom of the outer wall of the placing plate 201. The rotating shaft 206 is arranged on the inner wall of one end of the horizontal part of the fixing mechanism 1. A servo motor 207 is arranged at the bottom of the rotating shaft 206. A driving gear 208 is fixedly sleeved on the outer side of the top of the rotating shaft 206. The driving gear 208 meshes with the driven gear ring 205. When the four electric push rods 203 work, the four clamping plates 204 can clamp and fix rotors of different sizes. When the servo motor 207 works, the horizontal orientation of the rotor can be adjusted through the meshing between the driving gear 208 and the driven gear ring 205.

[0033] In order to conveniently perform welding operations on rotors of different sizes, as shown in Figure 2 and Figure 5 , the welding mechanism 3 includes a fixed seat 303. The fixed seat 303 is arranged on the outer wall of one side of the vertical part of the fixing mechanism 1. Hydraulic cylinders 301 are arranged at the tops of both ends of the fixed seat 303. A mounting seat 304 for installing a welding torch is rotatably installed on the outer wall of the fixed seat 303 away from the fixing mechanism 1. When the hydraulic cylinders 301 work, the height of the fixed seat 303 can be adjusted. The mounting seat 304 can install and fix the welding torch. The mounting seat 304 is rotatably connected on the outside of the fixed seat 303, and the inclination angle of the welding torch can be conveniently adjusted.

[0034] In order to keep the mounting base 304 stable during the height adjustment process, Figures 2 to 3 and Figure 5 As shown, the fixing mechanism 1 includes a fixed base plate 101, a fixed frame 102 is fixedly installed on one side of the top of the fixed base plate 101, movable grooves 103 are opened on the inner walls at both ends of the fixed frame 102, and sliders 302 are fixedly installed on both ends of the side of the fixed seat 303 close to the fixed frame 102, the outer walls of the two sliders 302 are movably connected to the inner walls of the two movable grooves 103 respectively, and the two ends of the top of the fixed frame 102 are fixedly connected to the two hydraulic cylinders 301 respectively, and the output ends of the two hydraulic cylinders 301 respectively pass through the tops of the inner walls of the two movable grooves 103 and are fixedly connected to the tops of adjacent sliders 302, and the movable grooves 103 can limit the movement of adjacent sliders 302, so that the fixed seat 303 and the mounting seat 304 remain stable during the height adjustment process.

[0035] In order to provide power for the horizontal azimuth adjustment of the rotor, such as Figures 2 to 4 As shown, the inner wall of one end of the fixed base plate 101 is rotatably connected to the rotating shaft 206, and one end of the bottom of the fixed base plate 101 is fixedly connected to the servo motor 207. The servo motor 207 and the rotating shaft 206 are connected by an output shaft transmission. The fixed base plate 101 can install and fix the rotating shaft 206 and the servo motor 207. The servo motor 207 works to rotate the rotating shaft 206. Through the meshing action between the driving gear 208 and the driven gear ring 205, the placement plate 201 can drive the rotor to rotate, and then the horizontal position of the rotor can be adjusted.

[0036] In order to keep the clamping plate 204 stable during the adjustment process, Figure 2 and Figure 4 As shown, the inner wall of the placement plate 201 is provided with four mounting grooves 202 in an annular shape at equal intervals, the inner walls of the four mounting grooves 202 are respectively fixedly connected to four electric push rods 203, and the inner walls of the four mounting grooves 202 are respectively movably connected to the outer walls at the bottom of four clamping plates 204, and the mounting grooves 202 can limit the movement of the clamping plates 204, so that the clamping plates 204 remain stable during the adjustment process, thereby enabling the clamping plates 204 to stably clamp rotors of different sizes.

[0037] The implementation manner is specifically as follows: When welding the motor rotor, the rotor to be welded is placed on the top of the placement plate 201. Then, by the operation of the four electric push rods 203, the four clamping plates 204 can be driven to move along the inner walls of the four installation grooves 202 respectively. Thus, the distance between the four clamping plates 204 can be adjusted so that the four clamping plates 204 can clamp and fix rotors of different sizes. Then, the welding torch is fixed inside the mounting seat 304. Then, the inclination angle of the welding torch and the mounting seat 304 is adjusted according to the height of the rotor. Then, the adjusted mounting seat 304 is fixed with a fixing pin so that it can be stably connected to the fixed seat 303. Further, by the operation of the two hydraulic cylinders 301, the two sliders 302 can be driven to move along the inner sides of the two moving grooves 103 respectively. Thus, the height of the welding torch can be adjusted so that it can weld different positions at different heights on the outer wall of the rotor. At the same time, the servo motor 207 operates to make the rotating shaft 206 rotate. Thus, the driving gear 208 rotates. Through the meshing action between the gear parts, the driven gear ring 205 rotates. Thus, the placement plate 201 can be driven to rotate. Thus, the horizontal orientation of the rotor can be adjusted so that the welding torch can conveniently weld different orientations of the rotor, improving the efficiency of rotor welding. This implementation manner specifically solves the problem in the prior art that the device cannot be conveniently adjusted according to the size of the rotor, resulting in low rotor welding efficiency.

[0038] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
