Description

Technical Field

[0001] The utility model relates to the technical field of terminal spot welding machines, in particular to a motor stator terminal spot welding machine. Background Technique

[0002] The working principle of the motor stator terminal spot welding machine is mainly based on the combination of electric energy and mechanical energy. Specifically, it first converts electric energy into heat energy through a power supply, making the resistance wire generate high temperature. Then, the workpiece is fed into the welding area. In the welding area, the welding electrode head contacts the workpiece, and the current passes through the workpiece and the electrode head to generate resistance heating, instantaneously melting the surface of the workpiece for welding.

[0003] Regarding the existing related technologies, the inventor believes that the following defects often exist: when spot welding the motor stator, workers need to hold the stator by hand and move it to the welding area, and then control the welding electrode head to contact the terminal for welding. Since multiple terminals need to be welded on one stator, workers need to manually control the rotation of the terminals, resulting in high working intensity and fatigue. At the same time, the hands of workers are in the welding area, posing a safety risk.

[0004] Therefore, we propose a motor stator terminal spot welding machine. Content of the Utility Model

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.

[0025] Example 1

[0026] Please refer to Figures 1 to 5 , an embodiment of the utility model provides a motor stator terminal spot welder, including: a bottom plate 1, and a spot welding assembly 2 for welding terminals is fixedly installed on one side of the top of the bottom plate 1;

[0027] On the other side of the top of the bottom plate 1, a linear motor one 4 is fixedly installed. The movable end of the linear motor one 4 is fixedly connected with a translation plate one 3. At the same time, walking wheels are installed on both sides of the bottom of the translation plate one 3. At the same time, the walking wheels roll on the top of the bottom plate 1 to translate. On both sides of the top of the translation plate one 3, equipment boxes 5 are welded. In the middle of the top of the translation plate one 3, a bracket 6 is welded. On the top of the bracket 6, a driving motor one 7 is fixedly installed. The driving end of the driving motor one 7 is fixedly connected with a rotating plate 8. On both sides of the end face of the rotating plate 8 close to the spot welding assembly 2, clamping assemblies 9 are rotatably installed. The two clamping assemblies 9 are alternately switched for use, which helps to improve the spot welding efficiency of the terminals. On the top of the equipment box 5 on the side close to the spot welding assembly 2, a driving source 10 for driving the clamping assembly 9 to rotate is fixedly installed.

[0028] The spot welding assembly 2 includes a chassis 21 and a spot welding machine host installed inside the chassis 21. On the top of the chassis 21, a first electric telescopic rod 26 is fixedly installed. And the movable end of the first electric telescopic rod 26 is in the welding area of the chassis 21. The movable end of the first electric telescopic rod 26 is fixedly installed with a moving electrode 25 through a mounting pad. A camera is also installed at the bottom of the mounting pad. At the rear side of the welding area of the chassis 21, a static electrode 24 is provided. And the static electrode 24 is square. The spot welding machine host is respectively connected with the static electrode 24 and the moving electrode 25 through wires. The spot welding machine is a mature existing technology, so it will not be elaborated here.

[0029] On the rear side of the inner wall of the chassis 21, a linear motor three is fixedly installed. An activity channel one 22 for the movable end of the linear motor three to pass through is opened on the chassis 21. The movable end of the linear motor three is fixedly connected with a lifting block 23. A conductive column is fixedly installed on the front of the lifting block 23. And the static electrode 24 is fixedly installed at the front end of the conductive column. The linear motor three drives the static electrode 24 to lift, and finely adjusts the position of the static electrode 24, and adaptively adjusts the position of the static electrode 24 according to stators of different sizes, which is suitable for welding stator terminals of different sizes.

[0030] The clamping assembly 9 includes a rotating hollow column 92 rotatably installed on the rotating plate 8. And the rotating hollow column 92 horizontally penetrates the rotating plate 8. One end of the rotating hollow column 92 far from the rotating plate 8 is welded with a U-shaped frame 93. One end of the rotating hollow column 92 far from the rotating hollow column 92 is welded with a disc 91. On both sides of the end of the disc 91 far from the U-shaped frame 93, abutting strips 96 are slidably installed.

[0031] The opposite sides of the two contact strips 96 are both arranged in an arc-shaped surface, and rubber sheets 95 are bonded and installed on the opposite sides of the two contact strips 96. The elastic deformation of the rubber sheets 95 will make the rubber sheets 95 fully contact with the inner hole of the stator to increase the friction coefficient and friction surface between the stator and the stator, thereby improving the stability of the stator clamping.

[0032] Therefore, linear motors 94 are fixedly installed on both sides of the U-shaped frame 93, and the movable end of the linear motor 94 is connected to one end of the resistance bar 96. Two movable channels 97 for the movable ends of the linear motors 94 are penetrated and opened on one side of the disk 91 close to the U-shaped frame 93.

[0033] The clamping assembly 9 clamps and fixes the stator, and the specific process is as follows:

[0034] The linear motors 94 on both sides are started at the same time to move the interference bars 96 on both sides toward the middle to shorten the distance between them, and the stator is put on the two interference bars 96, which are located in the inner hole of the stator. The linear motors 94 on both sides simultaneously drive the interference bars 96 to move sideways to expand the distance between the interference bars 96 on both sides, so that the rubber sheet 95 is in contact with the inner wall of the inner hole of the stator. The stator is clamped and fixed on the two interference bars 96 through the tension of the interference bars 96 on both sides toward the outside. The interference bars 96 on both sides move toward the middle, so that the clamped stator can be disassembled, thereby facilitating the assembly, disassembly and replacement of the stator to improve work efficiency. At the same time, the distance between the interference bars 96 on both sides is adjustable, which is suitable for clamping and fixing stators of different sizes, and has high adaptability.

[0035] The driving source 10 includes a translation plate 11 slidably mounted on the top of the equipment box 5, two slide rails are fixedly mounted on the top of the equipment box 5, and sliders sliding on the slide rails are fixedly mounted on both sides of the bottom of the translation plate 11. An electric telescopic rod 12 is fixedly mounted on the top of the equipment box 5 through a pad, and the movable end of the electric telescopic rod 12 is fixedly connected to one side of the translation plate 11, a driving motor 13 is fixedly mounted on the top of the translation plate 11, and a driving end of the driving motor 13 is fixedly connected to a magnet column 14, a magnet column 98 is fixedly mounted inside the rotating hollow column 92, and the opposing surfaces of the magnet column 98 and the magnet column 14 are in a magnetic adsorption state, and the two clamping components 9 are driven to rotate by a driving source 10, which effectively reduces the manufacturing cost and production cost.

[0036] The disc 91 is driven to rotate by the driving motor 13, and the stator is driven to rotate. When the stator is rotating, the terminals on the stator can be rotated to the top in turn and welded in turn. The rotation is driven by the machine, which reduces the work intensity and improves the welding efficiency.

[0037] The working principle of the utility model is:

[0038] During use, the terminal is fixed on the winding of the stator. The stator is clamped and fixed by the clamping assembly 9. After the clamping of the stator is completed, the driving motor 1 drives the rotating plate 8 to rotate, and the clamped stator is rotated to one side of the butt welding assembly 2. The linear motor 1 drives the first translation plate 3 to move towards one side of the butt welding assembly 2, and the terminal on the stator is moved between the static electrode 24 and the dynamic electrode 25. Then, the second electric telescopic rod 12 drives the second translation plate 11 to move towards the direction of the second magnet column 14, so that the second magnet column 14 enters the inside of the rotating hollow column 92 and contacts and magnetically attracts with the first magnet column 98;

[0039] Under the magnetic adsorption effect of the second magnet column 14 and the first magnet column 98, the driving motor 2 drives the disc 91 to rotate, driving the stator to rotate, and moving the terminal on the stator to the uppermost position. The linear motor 3 drives the lifting block 23 to move upward, so that the bottom of the uppermost terminal is located at the top of the static electrode 24. Then, the first electric telescopic rod 26 drives the dynamic electrode 25 to move downward and press on the top of the terminal, pressing the terminal between the static electrode 24 and the dynamic electrode 25 for welding. After the welding is completed, the dynamic electrode 25 moves upward, and the static electrode 24 moves downward to separate from the terminal, and continues to drive the terminal to rotate. In the rotating state of the stator, the terminals on the stator can be rotated to the uppermost position in turn and welded in turn;

[0040] After one terminal is welded, the second electric telescopic rod 12 shortens to separate the second magnet column 14 from the first magnet column 98. The driving motor 1 drives the rotating plate 8 to rotate, and the stators fixed on the two clamping assemblies 9 are swapped to weld the subsequent stators.
