A quick-change spot welding fixture

Abstract

The invention discloses a quick-change spot welding jig, comprising a quick-change plate, a base plate, supporting posts, third pins, fourth pins, locating columns, a press block and a locating block. The quick-change plate comprises a lower template, sliding blocks, a first fixing block, a second fixing block, a slide rail, handles and bottom die blocks, wherein the lower template is arranged on the base plate through the supporting posts, the bottom die blocks are arranged on the lower template, the sliding blocks are arranged on the bottom die blocks by the locating block, a groove is arranged in the central part of the front part of each sliding block, the press block is pressed in the grooves of the sliding blocks, the locating columns are fixedly arranged in the central part of the lower template through the fourth pins, and the slide rail is arranged in the central part of the front parts of the sliding blocks through the third pin. By using the quick-change spot welding jig, the waste on labors and the working time can be reduced, and products are conveniently placed or taken off through offline operation; meanwhile, the time waste is reduced, and the once laser spot welding is finished without multiple steps so that the sizes of the products are effectively managed.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a quick-change spot welding jig. Background technique [0002] Fixtures are often used in industrial production as a tool to assist in controlling position or movement, so as to facilitate pre-positioning of multiple products that require positioning installation, glue dispensing, welding or patching, etc., for mass production. Welding is a processing method that uses heat, pressure, or a combination of heat and pressure, and uses or does not use filler materials to achieve atomic bonding of welded parts. At the same time, welding is a method of connecting multiple separate metal parts into a non-detachable A method of machining a solid metal part. Among them, spot welding is a welding process commonly used in the welding of closely arranged workpieces. In order to improve production efficiency, it is usually thought of placing workpieces to be welded in a jig according to a c...

Problems solved by technology

However, in the process of placing the workpieces, each workpiece is easy to loosen and cheap, which leads to a high rate of welding defects. After the welding of the workpieces is completed, it is necessary to stop the machine and place the workpieces again, resulting in low production efficiency.
