Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figures 1 to 5 As shown, the embodiment of the utility model provides a motor rotor welding machine, comprising:

[0028] The bottom cross plate 1 has a chassis 6 welded on one side of the top of the bottom cross plate 1, and a welding machine host is installed inside the chassis 6. The welding machine host is an existing mature technology, so it is not described in detail. An electric telescopic rod 2 is installed on the top of the chassis 6, and the movable end of the electric telescopic rod 2 is located below the horizontal end of the chassis 6. The electric telescopic rod 2 is fixedly installed with an electrode rod 3 through a copper seat installed at its movable end.

The electric telescopic rod 2 5 is fixedly installed with an electrode rod 2 4 through a copper seat installed at its movable end. A rotating cross plate 7 is rotatably installed on the top of the bottom cross plate 1 and away from the side of the chassis 6. Both sides of the top of the rotating cross plate 7 are penetrated with connecting holes 71, and clamps 8 are installed on both sides of the top of the rotating cross plate 7 and directly above the connecting holes 71.

[0029] The fixture 8 includes a rotating ring 810 rotatably mounted on the top of the rotating horizontal plate 7 through a bearing, a carrying plate 85 is detachably mounted inside the rotating ring 810, a material hole 84 is penetrated through the center of the top of the carrying plate 85, arc-shaped clamping plates 83 are arranged on both sides of the top of the carrying plate 85 in an opposing state, and the rotor is clamped between the arc-shaped clamping plates 83 on both sides;

[0030] The rotor is clamped by the clamp 8 and rotated to the welding station for welding. During welding, the welding point of the rotor is adjusted during the meshing transmission of the gear 82 and the rotating ring 810 to achieve all-round welding of the rotor. Mechanical clamping replaces manual holding and manual rotation of the rotor, so that the workers' hands are away from the welding station, which improves the safety of welding. At the same time, the clamps 8 on both sides are used alternately, one is welding while the other is assembling and disassembling the rotor, which further improves the welding work efficiency and ensures the welding quality.

[0031] A driving motor 10 is installed on the top of the bottom cross plate 1 and on the side away from the chassis 6, and the driving end of the driving motor 10 is connected to the middle of the bottom of the rotating cross plate 7. Support legs are welded on both sides of the bottom of the rotating cross plate 7. Universal ball transfers 11 are installed at the bottom of the support legs, and the rolling end of the universal ball transfer 11 rolls on the top of the bottom cross plate 1.

[0032] The fixture 8 also includes a servo motor 81 installed on one side of the rotating circle 810. The servo motor 81 is fixed on the top of the rotating horizontal plate 7. A gear 82 is installed on the driving end of the servo motor 81. The outer wall surface of the rotating circle 810 is sleeved with an annular rack 89 meshing with the gear 82.

[0033] Angle plates 87 are welded to the four corners inside the rotating circle 810, and the supporting plate 85 is detachably installed between the tops of the four angle plates 87 by bolts. A threaded hole is opened on the top of the angle plate 87, and fixing holes are opened at the four corners of the top of the supporting plate 85. Fixing bolts threadedly connected to the threaded holes are arranged inside the fixing holes. The supporting plate 85 is detachably installed between the tops of the four angle plates 87 by bolts. The corresponding supporting plate 85 and the clamping parts arranged thereon can be replaced according to different rotors, so as to be suitable for clamping different rotors.

[0034] Two slideways 86 are provided on both sides of the top of the supporting plate 85, and limiting connecting bars 816 passing through the inside of the slideways 86 are welded to both ends of the bottom of the arc-shaped clamping plate 83, and a mounting bar 812 is installed between the two limiting connecting bars 816 on the same side, and a magnetic strip 811 is fixedly installed on one side of the mounting bar 812 close to the material hole 84.

[0035] Two groups of fixed protrusions 814 are installed on both sides of the bottom of the supporting plate 85, and a guide column 815 is welded between the opposite surfaces of the two fixed protrusions 814 in the same group. A slider 88 is slidably installed on the outer wall of the guide column 815, and the limiting connecting bar 816 is welded to the slider 88, and a spring 813 is sleeved on the outer wall of the guide column 815.

[0036] The process of clamping the rotor by the fixture 8 is as follows:

[0037] The electric telescopic rod 3 91 is extended to drive the lifting plate 92 to move upward, so that the magnetic strip 2 93 is located between the magnetic strips 1 811 on both sides. Under the magnetic repulsion between the magnetic strip 2 93 and the magnetic strip 1 811 on the same side, the magnetic strip 1 811 is pushed toward the fixed protrusion 814, so that the limit connecting strip 816 drives the arc-shaped clamping plate 83 to move toward the fixed protrusion 814, and the spring 813 is compressed by the slider 88 to expand the distance between the two arc-shaped clamping plates 83. At this time, the shaft of the rotor is inserted into the material hole. Inside 84, the rotor is placed on the top of the bearing plate 85, and then the electric telescopic rod three 91 is shortened to move the magnetic strip two 93 downward, contacting the repulsive effect of the magnetic strip two 93 on the magnetic strip one 811. Under the elastic reset action of the spring 813, the arc-shaped clamping plates 83 on both sides move toward the middle and reset, clamping the rotor between the arc-shaped clamping plates 83 on both sides. The rotor is clamped and fixed in a clamping installation manner, which is convenient for rapid assembly and disassembly of the rotor during welding, thereby improving the welding efficiency.

[0038] A discharge assembly 9 is installed on the top of the bottom cross plate 1 and on the side of the driving motor 10 away from the chassis 6. The discharge assembly 9 includes an electric telescopic rod 3 91 installed on the top of the bottom cross plate 1. The movable end of the electric telescopic rod 3 91 is fixedly connected to a lifting plate 92. Magnetic strips 2 93 are installed on both sides of the top of the lifting plate 92, and the opposite surfaces of the magnetic strips 2 93 and the magnetic strip 1 811 are in a magnetic repulsion state. By the lifting and lowering of the magnetic strip 2 93 and the magnetic repulsion between the magnetic strips 2 93 and the magnetic strip 1 811, the spacing between the arc-shaped clamping plates 83 on both sides is adjusted and controlled. There is no need for manual hand-held pulling and adjustment, which makes it easier to assemble and disassemble the rotor.

[0039] The working principle of the utility model is:

[0040] When in use, the electric telescopic rod 3 91 is extended to drive the lifting plate 92 to move upward, so that the magnetic strip 2 93 is located between the magnetic strips 1 811 on both sides. Under the magnetic repulsion between the magnetic strip 2 93 and the magnetic strip 1 811 on the same side, the magnetic strip 1 811 is pushed toward the direction of the fixed protrusion 814, so that the limit connecting bar 816 drives the arc-shaped clamping plate 83 to move toward the direction of the fixed protrusion 814, and compresses the spring 813 through the slider 88 to expand the distance between the two arc-shaped clamping plates 83. At this time, the shaft of the rotor is inserted into the inside of the material hole 84, and the rotor is placed on the top of the bearing plate 85. Then, the electric telescopic rod 3 91 is shortened to make the magnetic strip 2 93 move downward, contacting the repulsive effect of the magnetic strip 2 93 on the magnetic strip 1 811. Under the elastic reset action of the spring 813, the arc-shaped clamping plates 83 on both sides move to the middle and reset, clamping the rotor between the arc-shaped clamping plates 83 on both sides.

[0041] The driving motor 10 drives the rotating cross plate 7 to rotate, and rotates the drill to the bottom of the electrode rod 3. At this time, the electric telescopic rod 25 extends, and the electric telescopic rod 25 drives the electrode rod 24 to contact the bottom of the rotor, and then the electric telescopic rod 2 extends to drive the electrode rod 3 to move downward, and the electrode rod 3 is pressed on the required welding position of the rotor head and welded. After one welding is completed, the electric telescopic rod 2 drives the electrode rod 3 to move upward and reset, and the servo motor 81 drives the gear 82 to rotate. Under the meshing transmission action of the gear 82 and the annular rack 89, the rotating circle 810 is driven to rotate, and then the rotor is rotated to adjust a welding position, and then the electrode rod 3 moves downward again to weld the rotor, and so on and so forth, and the rotor is completely welded. After the rotor welding is completed, the electrode rod 3 and the electrode rod 24 are both separated from the rotor member and reset, and then the driving motor 10 drives the rotating cross plate 7 to rotate, and the clamps 8 at both ends are swapped, and the welding operation is performed again.

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