Abstract
The invention provides a positioning and clamping tool which is used for positioning and clamping a to-be-welded plate. The positioning and clamping tool comprises two clamping devices, which are arranged oppositely. Each clamping device comprises a base, one or more supporting block components, one or more clamping block components and a driving component. The supporting block components are arranged on the bases and are used for supporting the to-be-welded plate. The clamping block components are arranged on the upper sides of the supporting block components. The driving components are used for driving the clamping block components to rotate up and down. The clamping devices have the clamping state and the releasing state. When the clamping devices are in the clamping state, the driving components are used for driving the clamping lock components to rotate downwards to be close to the supporting block components so as to clamp the to-be-welded part. When the clamping devices are in the releasing state, the driving components are used for driving the clamping block components to rotate upwards to be far from the supporting block components so as to release the to-be-welded plate. The positioning and clamping tool has the advantages of being high in generality, reducing the production cost, shortening the delivery time, and improving the product competitiveness.
Description
Technical field
The present invention relates to a kind of frock clamp, particularly relate to the location clamping tool of a kind of general auxiliary welding.
Background technology
Traditional welding location clamping tool is usually two kinds of situations: 1, without the frock of auxiliary positioning clamping, helps with manpower and welds.2, simple frock or special tooling are manufactured and designed according to product structure feature.
In the case of the first, whole welding process is felt with individual entirely, and workpiece deformation severity, orthopedic time-consuming after welding, percent defective is high, does not has the quality assurance.The second situation is that most producer uses, and under this kind of form, workpiece welding deformation is inhibited, and welding precision improves, and quality has had basic guarantee.But owing to Products kind is many, model change is fast, and precision requirement is high, because of size, structure, profile difference, needs according to its structure, make corresponding Fixture Design.Simplest frock needs, through design, material purchases, cost processing and assembling process, to expend substantial amounts of human and material resources, financial resources, and cycle long, and efficiency is low.Such as, current automobile A column, B post, C post production technology can relate to the spot welding between two pieces of flat boards, after two pieces of plate weldings are good, carry out heat stamping and shaping again, but the profile of flat board, thickness, bond pad locations, number of welds etc. are required the most different by the automobile of different model, the corresponding location to two pieces of flat boards, support, clamped position also can there are differences, but typically concrete model can be used special Fixture Design in prior art.Therefore, above two frock form is difficult to meet the demand of production, goes out sample and date of delivery is long, and totle drilling cost is higher, and competitiveness is weak.
