Description

Technical Field

[0001] This utility model relates to the field of motor rotor processing, specifically a motor rotor welding equipment. Background Technology

[0002] The stator and rotor of an electric motor are important components of generators and starters. In the field of motor manufacturing, the motor rotor needs to be made by stacking multiple silicon steel sheets according to standards and then precisely welding the assembled silicon steel sheets. The precision of assembly and welding is crucial to the stability and efficiency of motor performance.

[0003] For example, patent CN221639811U discloses a laser welding mechanism for a motor rotor, including a base column, a worktable fixedly connected to the top of the base column, a turntable rotatably connected to the top of the worktable, a first support column fixedly connected to the top of the turntable, a second support column hinged to the top of the first support column, and an electric telescopic cylinder hinged to the top of the second support column. A laser welding head and an electronic eye are fixedly connected to the telescopic end of the electric telescopic cylinder. A limit groove is formed on the top of the worktable, and cylinders are respectively arranged on the left and right sides of the limit groove. Clamping blocks are fixedly connected to the output ends of the two cylinders, and toothed rubber pads are attached to the sides of the two clamping blocks that are close to each other.

[0004] The aforementioned patent uses an adjustable structure to limit the position of the laser welding head, allowing the laser welding head to be adjusted to weld the motor rotor from various angles. This solves the problem of insufficient flexibility in the use of existing laser welding mechanisms and improves the practicality, flexibility, and convenience of the device. However, the disadvantage of the aforementioned patent is that the rotor is fixed by a cylinder, and after fixing, the cylinder cannot rotate. The laser welding head needs to move to find the welding point on the rotor, resulting in low work efficiency.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0023] Please see Figure 1-5 A motor rotor welding device includes a support 1, a rotor fixing device 2, and a welding device 3.

[0024] Both the rotor fixing device 2 and the welding device 3 are mounted on the bracket 1;

[0025] The bracket 1 includes a workbench 101, and support legs 102 are fixedly installed at the four corners of the bottom of the workbench 101.

[0026] The rotor fixing device 2 includes a rotating motor 201 and a turntable bracket 202.

[0027] The turntable bracket 202 is fixedly installed on the top front end of the workbench 101, and the top of the turntable bracket 202 is rotatably connected to the turntable 204 through the first bearing 203. The rotating motor 201 is fixedly installed on the bottom of the turntable bracket 202.

[0028] A clamping cylinder 205 is fixedly installed on the top of the turntable 204, and a rotor clamp 206 is fixedly installed on the output shaft of the clamping cylinder 205.

[0029] Two rotor clamps 206 are provided and are arranged symmetrically to each other. The inner side of the rotor clamp 206 is provided with a clamping cavity 207 for clamping the rotor. When the clamping cylinder 205 is activated, the two rotor clamps approach each other to clamp the rotor.

[0030] The welding device 3 includes a mounting base 301, an X-axis adjustment mechanism 310, a Y-axis adjustment structure 330, and a reversing mechanism 340.

[0031] The top of the mounting base 301 is fixedly connected to the top frame 303 by the support column 302;

[0032] The X-axis adjustment mechanism 310 includes an X-axis adjustment motor 311, an X-axis first slide rail 312, an X-axis synchronous belt transmission mechanism 313, and a moving plate 320.

[0033] The Y-axis adjustment structure 330 includes a Y-axis adjustment motor 331, a Y-axis first slide rail 332, a Y-axis synchronous belt transmission mechanism 333, and a Y-axis second slide rail 334.

[0034] Two X-axis first slide rails 312 are provided and fixedly installed on the top left and right sides of the top of the top frame 303 respectively along the front-back direction. An X-axis moving block 315 is slidably connected to the X-axis first slide rails 312. The X-axis adjusting motor 311 is fixedly installed on the rear left side of the top frame 303. The X-axis adjusting motor 311 drives the X-axis synchronous belt transmission mechanism 313, which is arranged on the top left side of the top frame 303 along the front-back direction. The synchronous belt of the X-axis synchronous belt transmission mechanism 313 is fixedly connected to the side of the X-axis moving block 315 through a synchronous belt clamp.

[0035] The bottom of the movable plate 320 is also provided with a second X-axis slide rail 321 along the front and rear sides, and a first Y-axis slide rail 332 is also provided along the left and right sides of the bottom rear side of the movable plate 320; the second Y-axis slide rail 334 is fixedly installed on the top front end of the top frame 303 along the left and right sides; a Y-axis moving block 335 is slidably connected to the top of the second Y-axis slide rail 334, and the Y-axis moving block 335 is connected to the Y-axis synchronous belt transmission mechanism 333; at the same time, the top of the Y-axis moving block 335 is also slidably connected to the second X-axis slide rail 321; the Y-axis adjusting motor 331 is fixedly installed on the right side of the bottom front end of the top frame 303; the Y-axis adjusting motor 331 drives the Y-axis synchronous belt transmission mechanism 333; the top of the X-axis moving block 315 is slidably connected to the first Y-axis slide rail 332;

[0036] The reversing mechanism 340 includes a reversing motor 341 and a reversing seat 342, with the reversing motor 341 fixedly mounted on the top of the movable plate 320;

[0037] A commutator seat 342 is fixedly installed at the front end of the output shaft of the commutator motor 341, and a laser welding head 4 is fixedly installed at the front end of the commutator seat 342.

[0038] In this design, both the X-axis synchronous belt drive mechanism 313 and the Y-axis synchronous belt drive mechanism 333 include a driving pulley, a driven pulley, and a synchronous belt.

[0039] When this solution is put into use, the rotor to be welded is placed in the rotor clamp 206, and the clamping cylinder 205 is activated to clamp the rotor; the rotating motor 201 can be activated to rotate and adjust the clamped rotor so as to facilitate welding the rotor in various directions on the side.

[0040] When it is necessary to adjust the position of laser welding head 4:

[0041] When the position in the X-axis direction needs to be adjusted, the X-axis adjusting motor 311 is activated. The X-axis adjusting motor 311 drives the X-axis moving block 315 to move along the X-axis direction through the X-axis synchronous belt transmission mechanism 313. The first Y-axis slide rail 332, which is slidably connected above the X-axis moving block 315, is set along the left-right direction (i.e., the Y-axis direction). The X-axis moving block 315 will drive the moving plate 320 to move along the X-axis. At the same time, since the second X-axis slide rail 321 below the moving plate 320 is set along the front-back direction, the Y-axis moving block 335, which is fixed in the X-axis direction, will not obstruct the moving plate 320 from moving along the X-axis.

[0042] When the position in the Y-axis direction needs to be adjusted, the Y-axis adjustment motor 331 is activated. The Y-axis adjustment motor 331 drives the Y-axis moving block 335 to move along the Y-axis through the Y-axis synchronous belt transmission mechanism. Since the X-axis second slide rail 321 above the Y-axis moving block is set in the front-back direction, the Y-axis moving block can drive the moving plate 320 to move along the Y-axis (i.e., move in the left-right direction).

[0043] Since the first slide rail 332 on the Y-axis is set along the left and right direction (i.e. the Y-axis direction), the X-axis moving block 315 fixed on the Y-axis will not obstruct the movement of the moving plate along the Y-axis.

[0044] When it is necessary to adjust the angle of the laser welding head 4, the reversing motor 341 drives the reversing seat 342 to rotate, which in turn drives the laser welding head 4 to rotate.

[0045] Meanwhile, in order to more accurately control the rotary motor 201, the X-axis adjusting motor 311, the Y-axis adjusting motor 331, and the commutator motor 341, all of these motors are stepper motors.
