Description

Technical Field

[0001] The utility model relates to the technical field of spot welding, in particular to an automatic spot welding device for a stator ventilation slot plate. Background Art

[0002] The stator ventilation slot plate is a part of the stator core of an electric motor. Its main function is to provide a ventilation and heat dissipation channel to reduce the temperature generated during the operation of the motor. The structure of the stator ventilation slot plate is diverse, but generally includes a ring-shaped ventilation slot plate punching sheet. A plurality of notches are evenly arranged on the inner peripheral edge of the punching sheet. A plurality of first ventilation slot sheets are evenly arranged along the radial direction on the sheet body of the ventilation slot plate punching sheet. There are two notches spaced between adjacent two first ventilation slot sheets. A second ventilation slot sheet is arranged on the sheet body of the ventilation slot plate punching sheet between adjacent two first ventilation slot sheets. The second ventilation slot sheet extends from the outer side of the end of one of the notches to the outer periphery of the ventilation slot plate punching sheet, parallel to the first ventilation slot sheet adjacent to the other notch. The shape design of the ventilation groove usually considers comprehensive factors such as heat dissipation effect and manufacturing process, such as a rectangular or trapezoidal cross-section, to increase the heat dissipation surface area and facilitate manufacturing and installation.

[0003] Spot welding is an important link in the manufacturing process of the stator ventilation slot plate, mainly used to firmly connect the I-beam with the punching sheet to form a complete ventilation slot plate structure. After retrieval, the patent application No. CN202223066761.6 discloses an automatic welding device for a ventilation slot plate of a generator, belonging to the field of automatic welding machines. It includes a welding machine main body. A welding fixture is installed at the upper end of the welding machine main body. A blowing device is installed at the upper end of the welding machine main body. The blowing device is located in front of the welding fixture. The blowing device includes a substrate structure, a high-pressure air nozzle, and a connecting air pipe. The high-pressure air nozzle and the connecting air pipe are both installed on the substrate structure. The connecting air pipe is simultaneously connected to an externally arranged air compression device. By arranging a blowing device on one side of the welding fixture, the welding fixture can be continuously blown, so that the sundries that are about to roll onto the welding fixture can be blown away, thereby avoiding the sundries from rolling into the welding jacks opened on the fixed pressing plate, and finally avoiding the welding jacks from being blocked, and avoiding the sundries from blocking the welding equipment from inserting into the welding jacks to weld the stator punching sheet and the ventilation channel steel installed in the welding fixture. It only avoids the sundries from rolling into the welding jacks opened on the fixed pressing plate and causing blockage by blowing away the waste materials, and cannot collect the odorous gas or impurity fragments generated during the spot welding process, resulting in the need for manual cleaning after the subsequent spot welding is completed; this spot welding device only has one welding station, so only one stator ventilation slot plate can be welded at the same time, and the efficiency is low.

[0004] Therefore, it is necessary to design an automatic spot welding device for a stator ventilation slot plate to solve the above-mentioned problems. Summary of the Utility Model

One station welds the workpiece with a length of 50 cm, and the other station welds the workpiece with a length of 30 cm), so the practicability is stronger.

[0027] Specifically, please refer to Figure 1 , Figure 3 and Figure 4, the fixed structure 2 includes a bearing plate 21 fixedly installed on the top of the second body 7. There is a notch 22 parallel to its long side between the bearing plates 21. A threaded rod 23 is arranged inside the notch 22.
