Description

Spot welding jig structure Technical Field The application relates to the field of welding jigs, in particular to a spot welding jig structure. Background Inductance is a basic electronic component which is extremely widely used and mainly consists of a coil, a magnetic core and an electrode, and the quality of the coil has a great influence on the quality of the inductance. In the manufacturing process of some integrated inductors, a plurality of coils and a limiting arm in the same square terminal are required to be fixed by spot welding so as to form a plurality of inductors at one time later. For example, a jig for spot welding an inductance coil and a terminal, with the publication number CN215846270U, is to put the coil into a cavity of the jig and sleeve the coil in the center pillar, and the limiting arm of the terminal is also located in the cavity to locate and place the coil pin in contact with the coil pin, and then the cover plate is pressed down to stabilize the periphery of the terminal. For the related art, when the type of the inductor to be produced is changed, the size of the coil is correspondingly changed, so that the jig is correspondingly replaced, and various jigs are required to be prepared, so that the cost of the jig is relatively high. Disclosure of utility model In order to improve the universality of the jig and reduce the cost, the application provides a spot welding jig structure. The spot welding jig structure provided by the application adopts the following technical scheme. The utility model provides a spot welding tool structure, includes the pedestal that supplies the terminal to place, the pedestal surface shaping has several can contact in terminal periphery to terminal location's reference column, and the pedestal sets up the surface penetration shaping of reference column has the seat mouth, and the opening that seat mouth was kept away from reference column one side supplies the coil directional to move in so that the coil pin contacts in the spacing arm of terminal. Through adopting above-mentioned technical scheme to when the size of coil takes place certain change, the coil also can pass enough big seat mouth, and the change of the size of coil in certain limit can not cause the change of terminal size simultaneously, just also need not change the pedestal, promotes the tool commonality, in order to reduce the tool cost, reduces the coil cost. Optionally, the seat body is penetrated and provided with two end holes for the cover plate to correspondingly bulge and insert so as to pull the seat body. By adopting the technical scheme, the welded terminal and the coil are pulled by the seat body to move to the corresponding station for taking out and putting in a new terminal. Optionally, the end hole supplies the apron to correspond the convex male one end opening part and can dismantle and be connected with the abrasionproof ring, and abrasionproof ring internal diameter is less than or equal to the end hole internal diameter. By adopting the technical scheme, the abrasion caused by the fact that the end hole is inserted into the cover plate in a relatively frequent inserting process is reduced, so that the whole seat body does not need to be replaced after the jig is used for a long time. Optionally, an annular channel for tightly placing the anti-wear ring is formed at the opening of one end of the end hole, where the anti-wear ring is arranged. By adopting the technical scheme, when the end hole cannot be protected any more due to larger abrasion of the anti-abrasion ring, the anti-abrasion ring can be taken out conveniently and a new anti-abrasion ring can be put in conveniently. Optionally, the wear ring manufacturing material comprises copper. By adopting the technical scheme, the anti-wear ring is manufactured by adopting copper with better wear resistance and lubricity. Optionally, the surface of the positioning column facing the terminal is arc-shaped. By adopting the technical scheme, the terminal and the positioning column are in line contact, so that abrasion to the terminal is reduced. Optionally, the periphery of one end of the positioning column far away from the base is formed with an inclined guide surface, and the sectional area of one end of the positioning column far away from the base is minimum. By adopting the technical scheme, the terminal is conveniently placed between all the positioning columns. Optionally, the base body manufacturing material comprises iron. By adopting the technical scheme, the durability of the seat body is improved. In summary, the present application at least includes the following advantages. 1. When the size of the coil changes to a certain extent, the coil can pass through a sufficiently large seat, and meanwhile, the change of the size of the coil within a certain range can not cause the change of the size of the terminal, so that the seat body is not required to be replaced, the universality of the jig is improve
