Clamping method for automobile welding

Abstract

The invention discloses a clamping method for automobile welding. According to the technical scheme, a workpiece is clamped on a placing block, the clamping method comprises the following steps that aheightening block extends to a proper position to enable the height of a lower pressing block to be higher than the position of an upper pressing block and to enable the lower pressing block to be incontact with the bottom surface of the workpiece, at the moment, a manipulator pneumatic rod is used for controlling a manipulator to release the workpiece, then a manipulator mounting seat goes backthe same way, a rotating rod rotates to a proper angle to enable the workpiece to be capable of avoiding the lower pressing block to move downwards, then the heightening block is retracted to the original height, a lifting rod rises to a proper height to be higher than the height of the workpiece, then the rotating rod rotates to a proper angle to enable the side part of the workpiece to be justpositioned below the upper pressing block, a pushing block is pushed by the clamping pneumatic rod, and then the workpiece is clamped through the upper pressing block. The clamping method has the advantages that the structure is reasonable and simple, the production cost is low, the installation is convenient, the multiple-degree-of-freedom limitation can be carried out on materials with differentsizes and different shapes so as to ensure that complete clamping of the material is achieved, and then the quality of a product obtained by welding can be ensured.

Description

Technical field: [0001] The invention relates to the technical field of automobile processing, in particular to a clamping method for automobile welding. The present invention is an application number: 2017106490262, application date: 2017.08.01, invention name: a divisional application of a welding device for automobile processing and manufacturing. Background technique: [0002] At present, the development of steel or other materials will put forward newer, higher and more requirements in many aspects such as welding technology and its process, consumables, equipment, automation, efficiency, cost, life, maintenance, and remanufacturing. Welding methods are developed complementary to each other under the impetus of the development of modern industry and science and technology. It can be predicted that with the continuous development of modern industry and science and technology, there will be new developments in welding technology and equipment. Therefore, welding fixture...

Problems solved by technology

However, the existing welding fixtures have some disadvantages during use. First, the size of the fixture itself is fixed, but the metal materials to be welded are of different sizes, so often there will be inconsistency between the fixtures. This will directly affect the efficiency of work and the quality of products; secondly, most of the existing fixtures only limit a single degree of freedom. When clamping materials on curved surfaces, there will often be a little slip, but This greatly affects the welding effect and reduces the accuracy of the product
