TECHNICAL FIELD

[0001] The utility model relates to the field of vacuum circuit breaker base welding, specifically is a kind of vacuum circuit breaker base welding jig. BACKGROUND

[0002] Vacuum circuit breaker is a kind of high voltage switchgear using vacuum as insulation and arc-extinguishing medium, and the vacuum circuit breaker base is made of metal material. During assembly and processing, it needs to be welded and assembled. In order to increase the welding accuracy of the circuit breaker base, a welding jig needs to be used for assistance.

[0003] The existing vacuum circuit breaker base welding jig, such as the manual welding jig for chip transformer welding proposed in patent application number "CN202321400298.6", includes structures such as limiting pressure block, pin limiting hole, pressure buckle slot and base, which can effectively limit the transformer, avoid displacement during transformer welding, and avoid assembly failure and poor assembly.

[0004] However, the existing technology has defects, as it cannot limit the welding position of the parts on the transformer, and the parts still lack limiting during welding, which may cause the welding position of the parts to deviate. Therefore, a vacuum circuit breaker base welding jig is proposed. SUMMARY

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] A welding fixture for a vacuum circuit breaker base. Figures 1-4 As shown, the fixture includes a positioning plate 2, which is inserted and installed on the base body 1. Multiple sets of positioning pins 4 and positioning posts 5 are inserted and installed on the positioning plate 2. The multiple sets of positioning pins 4 and positioning posts 5 are all inserted and installed on the base body 1. The positioning plate 2 has a through-hole 3 corresponding to the position of the part to be welded on the base body 1. The installation hole 3 is used for part insertion. A welding space is provided between the lower end of the positioning plate 2 and the upper end of the base body 1.

[0024] By opening a suitable mounting port 3 at the location of the part to be welded on the positioning plate 2 corresponding to the base body 1, the positioning plate 2 is made to match the shape of the vacuum transformer base. The base body 1 is erected and fixed in position using an external structure. The positioning pin 4 and positioning post 5 on the positioning plate 2 are inserted into the base body 1. The part is inserted into the mounting port 3, and the welding end of the part is in close contact with the base body 1. The gap between the part and the base body 1 is spot welded through the welding space. The positioning plate 2 limits the welding position of the part, prevents the welding position of the part from shifting, and improves the welding accuracy of the parts on the vacuum circuit breaker base. After welding is completed, the positioning plate 2 is removed, and the positioning plate 2 can be used again for the next set of base bodies 1 with the same shape.

[0025] like Figure 1 As shown, the mounting port 3 is provided in multiple sets, and the multiple sets of mounting ports 3 are respectively located between multiple sets of positioning pins 4. One end of the positioning plate 2 is provided with a positioning port 10, which is used to distinguish the installation position of the positioning plate 2.

[0026] Positioning pins 4 are distributed around the mounting port 3, and the positioning port 10 makes it easy for users to distinguish the left and right orientation of the positioning plate 2.

[0027] like Figures 3-4 As shown, multiple sets of abutment blocks 8 are fixedly connected to the lower end of the positioning plate 2. All sets of abutment blocks 8 abut against the upper end of the base body 1. The abutment blocks 8 are used to form a welding space between the lower end of the positioning plate 2 and the upper end of the base body 1.

[0028] The height of the abutment block 8 is less than the height of the positioning pin 4. The abutment block 8 is not inserted into the base body 1, which limits the insertion length of the positioning pin 5 into the base body 1, so that there is a certain height between the positioning plate 2 and the base body 1, thereby forming a welding space, and spot welding is performed on the gap between the parts and the base through the welding space.

[0029] like Figure 4 As shown, the positioning plate 2 has oblique notches 11 on both sides, which are used to reduce the welding distance of the mounting port 3.

[0030] The oblique notch 11 reduces the distance between the edge of the positioning plate 2 and the mounting opening 3, making spot welding easier.

[0031] like Figures 1-4 As shown, the upper end of the positioning plate 2 is fixed to the mounting plate 7 by bolts, and a pull ring 6 is fixed to the mounting plate 7.

[0032] Mounting plate 7 can be installed by bolts or by welding. Bolts make it easier to install and remove mounting plate 7, while pull ring 6 makes it easier for workers to lift positioning plate 2 and provides a point of leverage for workers to pick up positioning plate 2.

[0033] like Figure 3 As shown, the lower end of the positioning plate 2 is provided with a slot 9, which is used to reduce the weight of the positioning plate 2.

[0034] The empty slot 9 will not affect other structures, will reduce the weight of the positioning plate 2, and will make it easier to operate.

[0035] The working principle of the vacuum circuit breaker base welding fixture provided by this utility model is as follows:

[0036] By opening a suitable mounting port 3 at the position of the part to be welded on the positioning plate 2 corresponding to the base body 1, the positioning pin 4 and positioning post 5 on the positioning plate 2 are inserted into the base body 1, and the abutment block 8 abuts against the upper end of the base body 1 to form a welding space. The part is inserted into the mounting port 3, and the welding end of the part is in close contact with the base body 1. The gap between the part and the base body 1 is spot welded through the welding space. The positioning plate 2 limits the welding position of the part, prevents the welding position of the part from shifting, and improves the welding accuracy of the parts on the vacuum circuit breaker base.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
