Description

Projection welding clamp Technical Field The utility model relates to the technical field of welding, in particular to a projection welding clamp. Background Projection welding is a high-efficiency welding method capable of simultaneously performing multiple-point welding, and is a resistance welding method in which one or more convex points are machined in advance on the joint surface of one workpiece, are contacted with the surface of the other workpiece, are electrified and heated, and then are collapsed, so that welding points are formed on the contact points. The projection welding nut (the nut with the convex points) is welded on the sheet, so that only the bolt is needed to be screwed when the sheet is assembled, and the assembly work efficiency is improved. When the projection welding nut is welded on the thin plate, the projection welding nut needs to correspond to the hole in the thin plate, and when the projection welding nut corresponds to the hole in the thin plate, a worker needs to correspondingly adjust, so that the speed is not high. In view of this, we propose a projection welding jig. Disclosure of utility model The utility model aims to provide a projection welding clamp which is used for solving the problems in the background technology. In order to achieve the purpose, the utility model provides the technical scheme that the projection welding clamp comprises a base and a supporting plate, wherein a support column is fixedly arranged on the base, a supporting plate is fixedly arranged at the top of the supporting plate, the supporting plate is arranged on the supporting plate, and a plate is placed on the supporting plate; the upper surface of the bearing plate is fixedly provided with a plurality of limit posts, a plurality of limit posts are matched with a plurality of holes formed in the plate in a penetrating mode, and projection welding nuts placed on the plate are matched with the tops of the limit posts in an inserting mode. Preferably, the top of the limit post is positioned in the projection welding nut. Preferably, the backup pad tip is provided with the clamping structure, the clamping structure includes fixed block and positive and negative tooth screw rod, the through groove in fixed block is connected with the bearing, positive and negative tooth screw rod passes through the bearing and rotates with the fixed block to be connected, positive and negative tooth screw rod's tip fixation is provided with the twist grip, two screw thread sections of positive and negative tooth screw rod are threaded respectively and are overlapped and are equipped with splint, two one side centre gripping cooperation of the front and back end of splint and bearing board. Preferably, the upper surface of the supporting plate is provided with a slot, the lower surface of the supporting plate is fixedly provided with a cutting, and the cutting is matched with the slot in an inserting way. Preferably, one side of the front end and the rear end of the bearing plate is respectively provided with a limiting groove, two opposite sides of the clamping plates are respectively fixedly provided with limiting blocks, and the limiting blocks are matched with the limiting grooves in an inserting mode. Preferably, one end of the fixing block is fixedly provided with a guide bar, and one end of each clamping plate is slotted and is respectively in sliding fit with the guide bar. Compared with the prior art, the utility model has the beneficial effects that: 1. The utility model has the advantages that the plate is positioned on the support plate through the butt joint of the limit column and the hole and the butt joint of the projection welding nut and the top of the limit column by arranging the support plate and the limit column, so that the projection welding nut can be quickly and accurately placed on the plate, and the problem that a worker needs to correspondingly adjust when the projection welding nut corresponds to the hole on the thin plate is solved. 2. The utility model has the advantages of selecting proper bearing plates according to different correspondence of plate members, positioning the bearing plates and keeping the bearing plates stable by arranging the fixing blocks, the bearings, the positive and negative tooth screws, the rotating handles, the clamping plates and the guide strips.
