Description

Technical Field

[0001] This invention belongs to the technical field of motor production equipment, specifically relating to the winding welding pads and their tensioning mechanism for new energy motors. Background Technology

[0002] The wiring harness structure of new energy vehicle motors is complex. During production, copper wire is first cut into segments of a certain length, then subjected to processes such as paint stripping, U-shaped bending, and 3D molding to form a U-shaped wire. This U-shaped wire is then inserted into the motor stator, forming multi-layer windings. Finally, the windings are welded together to obtain the motor wiring harness. Before welding, the windings have numerous wire ends, and the copper wire itself undergoes deformation during insertion, leading to misalignment between the wire ends that need to be welded in the completed windings, affecting the normal progress of the welding process. Therefore, a tooling fixture needs to be designed to effectively position the winding wire ends before welding, facilitating the subsequent welding work. Summary of the Invention

[0015] like Figure 1-3As shown, the new energy motor winding welding pad and its tensioning mechanism are illustrated. The welding pad includes a frame 1, an upper turntable 3, and a lower turntable 2. The upper turntable 3 is located above the lower turntable 2. The upper turntable 3 and the lower turntable 2 are rotatably mounted on the frame 1. The upper turntable 3 has several upper clamping openings 4, and several upper slots 5 are provided on one side of each upper clamping opening 4. The lower turntable 2 has several lower clamping openings 6, and several lower slots 7 are provided on one side of each lower clamping opening 6. The upper clamping openings 4 and lower clamping openings 6 correspond one-to-one. The upper slots 5 and lower slots 7 are connected to each other. The slots 7 correspond one-to-one, and the upper clamping opening 4 and the corresponding lower clamping opening 6 form a clamping opening. The upper locking slot 5 and the corresponding lower locking slot 7 are located on both sides of the clamping opening. The frame 1 is provided with a sliding groove 8, and a linkage slider 9 is provided in the sliding groove 8. The inner side of the linkage slider 9 is provided with a movable groove 10. A pointed wedge 12 is connected to the middle of the movable groove 10. Guide inclined surfaces 13 are provided on both sides of the pointed wedge 12. Inner inclined surfaces 11 are provided on both sides of the movable groove 10. The upper turntable 3 is fixedly connected to an upper swing arm. 14. The lower turntable 2 is fixedly connected to a lower swing arm 15. Both the lower swing arm 15 and the upper swing arm 14 are inserted into the movable slot 10. The inner side of the lower swing arm 15 is provided with a guide inclined surface 16, and the outer side of the lower swing arm 15 is provided with a guide protrusion 17. The upper swing arm 14 and the lower swing arm 15 have the same structure and are symmetrically arranged. The linkage slider 9 is provided with a circular groove 18, and a limiting circular plate 19 is provided in the circular groove 18. The linkage slider 9 is provided with a movable hole 20 that connects to the circular groove 18. The frame 1 is provided with a threaded hole, and the threaded hole contains a threaded hole. A screw 21 is connected to the threaded connection. One end of the screw 21 moves through the movable hole 20 and is fixedly connected to the limiting circular plate 19. The other end of the screw 21 is fixedly connected to the nut 22. The tightening mechanism includes a rotating tube 111, which has a groove for the nut 22 to be inserted into. The rotating tube 111 is driven to rotate by a rotation drive mechanism 112, translated by a horizontal drive mechanism 113, and moved vertically by a vertical drive mechanism 114. By using the horizontal drive mechanism 113 and the vertical drive mechanism 114, the position of the rotating tube 111 is adjusted so that it is directly opposite the screw 21 and the screw 21 is inserted into the groove of the rotating tube 111. Then, the rotation drive mechanism 112 drives the rotating tube 111 to rotate, which drives the screw 21 to rotate. The screw 21 engages with the threaded hole, resulting in linear displacement, which drives the linkage slider 9 to move within the slide groove 8. The pointed wedge 12 moves forward, and through the cooperation of the guide ramp 13 and the guide inclined surface 16, it pushes the lower swing arm 15 and the upper swing arm 14 to both sides respectively, causing the upper turntable 1 and the lower turntable 2 to rotate relative to each other. When the upper turntable 1 and the lower turntable 2 rotate relative to each other, the clamp formed by the upper clamp 4 and the corresponding lower clamp 6 narrows, pushing the wire ends in the clamp into the upper slot 5 and the corresponding lower slot 7 respectively, thereby ensuring that all wire ends are accurately positioned, facilitating the welding equipment to weld the wire ends.When the screw 21 rotates in the opposite direction, it drives the linkage slider 9 to retract in the slide groove 8, the pointed wedge 12 retracts, and the inner inclined surface 11 retracts, causing the guide protrusion 17 in contact with it to move, which drives the upper swing arm 14 and the lower swing arm 15 to rotate relative to each other and reset, and the clamping jaws widen.

[0016] Furthermore, the lower swing arm 15 includes an arm body and an arm head 30 fitted onto the arm body. A guide inclined surface 16 is located on the inner side of the corresponding arm head 30, and a guide protrusion 17 is located on the outer side of the corresponding arm head 30. This facilitates the processing of the upper turntable 3 and the lower turntable 2. The upper turntable 3 and the lower turntable 2, having the same structure, only require the arm heads 30 to be fitted onto them in different directions after processing. The arm heads 30 are uniformly processed and directly fixed to the arm body using screws.

[0017] Furthermore, the frame 1 is provided with connecting ears 31 on both sides, and the connecting ears 31 are provided with several positioning holes 32. This facilitates the use of a robotic arm to grasp the solder pads. The robotic arm clamps the connecting ears 31 at both ends, and the robotic arm is designed with pins that can be inserted into the positioning holes 32. This allows for stable grasping of the solder pads, which can then be placed on or removed from the motor stator.

[0018] Furthermore, the rotation drive mechanism 112 is a rotation motor, the lateral drive mechanism 113 includes a lateral cylinder and a lateral slide plate 140, the lateral cylinder drives the lateral slide plate 140 to move, the rotation motor is fixedly connected to the lateral slide plate 140, and the vertical drive mechanism 114 includes a vertical linear motor, the vertical linear motor drives the lateral cylinder to move vertically.

[0019] Furthermore, the nut 22 is a hexagonal nut. Correspondingly, the cross-section of the slot is also designed to be hexagonal. After the hexagonal nut is inserted into the slot, the screw 21 can rotate clockwise or counterclockwise with the rotating tube 111.

[0020] It is worth mentioning that the technical features of motors, cylinders, etc. involved in this patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this patent.
