In a broad sense, any process in the process, the device used to quickly, easily and safely install the workpiece can be called a fixture. Welding tooling design is one of the important contents of production preparation and one of the main tasks of welding production process design. To this end, practicality, economy, reliability, and artistry must be considered when designing the welding tooling.
When processing the workpiece on the machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometry and accuracy of mutual position with other surfaces, the workpiece must be installed (positioned) and clamped (clamped) before processing. During the mechanical design and manufacturing process, dimensional chain problems are common. Dedicated fixtures that can be replaced or adjusted. Most of them have become a standard accessory for machine tools. Designing fixtures is no exception. Such as machine vices, chucks, indexing heads, and rotary tables, etc. The sequence 1 struts are positioned by the blocking pins and baffles. The sequence 1 strut is clamped by a screw clamp; at the same time, the two pieces of the sequence 4 engine liner are positioned by a bolt, and clamped by a quick-release screw clamping device. Commonly used are lathe fixtures, milling machine fixtures, drilling dies (machine tool fixtures for guiding tools to drill holes or reaming on workpieces), boring dies (machine tool fixtures for guiding boring bars for boring on workpieces) and accompanying fixtures (for On the automatic line of the combined machine tool). (3) Apply anti-embroidery oil after use.
Outline, experience and suggestions for the design of this course Most welding tools are specially designed for the gathering and welding process of a certain welding gathering.What is an inspection fixture? The device used to fix the processing object in the machine manufacturing process so that it has the correct position to accept construction or testing. Fixtures are usually composed of positioning elements (determining the correct position of the workpiece in the fixture), clamping devices, tool guide elements (determining the relative position of the tool to the workpiece or guiding the direction of the tool), and indexing devices (allowing the workpiece to be installed in a single installation) Finished processing at several stations, including rotary indexing device and linear moving indexing device), connecting elements and clamps (fixture base). This forms the interaction between the dimensional error and the comprehensive error of the part.. In the process of gathering parts into a machine, that is, combining and accumulating the relevant dimensions on the parts. Special fixture.
