Abstract

The invention discloses an automatic internal-supporting tool clamp for the pre-welding assembly of a special-shaped component. The invention aims to solve the problems of inaccurate centering, untight clamping, poor assembly precision and low assembly efficiency during the pre-welding assembly of the special-shaped structure of a shell type space. The clamp comprises a base body module, a movement module, a power module and a control module. The movement module is located at the end face of the base body module. The power module and the control module are both arranged in the base body module. When the clamp works, the control module controls the power module to output power, the movement module located at the end face is driven by the power module to clamp a workpiece, and the base bodymodule is used for positioning in the clamping process and protecting the control module and the power module. The method is applied to the field of welding.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to an automatic inner support tooling fixture for pre-welding assembly of special-shaped components. Background technique [0002] Welding technology occupies an extremely important position in today's national manufacturing industry, and has been more and more widely used. After decades of development, welding technology has formed a relatively complete system in my country's energy industry, transportation industry, aerospace industry and ocean engineering. In recent years, with the development of modern welding technology and the needs of the manufacturing industry, scientific and rational design of fixtures is becoming more and more important. The prerequisite for welding parts is to make fixtures to install and fix each part accurately and scientifically. Fixtures have a direct and key impact on the quality, cost and productivity of welding parts. Compared with the traditional cutting fix...
