Introduction of welding fixture

Welding fixture is a process device used to quickly fasten the workpiece and keep it in the correct relative position during processing. That is to say, tooling fixture is an indispensable part of machining. Fixtures are also called fixtures.

Broadly speaking, in any process in the process, a device used to quickly, conveniently and safely install a workpiece can be called a fixture. Driven by the development of technology towards high-speed, high-efficiency, precision, intelligence, and environmental protection, fixture technology is developing in the direction of high-precision, high-efficiency, modular, combined, universal, and economical. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Often referred to as a fixture for short.

When processing a workpiece, in order to make the surface of the workpiece meet the technical requirements of the size, geometric shape and mutual position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before processing. The application of fixtures helps to ensure the processing accuracy of the workpiece and stabilize the product quality; it is beneficial to increase labor productivity and reduce costs; it is beneficial to improve the labor conditions of workers and ensure safe production; it is beneficial to expand the process range and realize "one machine with multiple uses".

Scope of use of fixtures

The fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, an indexing device, so that the workpiece can be processed in several stations in one installation, with a rotary indexing device and a linear moving indexing device It is composed of two types, connecting elements and clamp body (fixture base). The usage rate of fixtures in the factory is very high. In order to improve production efficiency and product quality in production, fixtures are commonly used in the middle and later stages of production for functional testing or auxiliary assembly (which can be assembled with a fixed shape and height, etc. ). The actual use in the manufacturing plant is very wide, because it is non-standard and customized, so as long as you think of it, you can make it.
