The hero models on the fixture can be adjusted or replaced to adapt to multiple workpiece processing fixtures, called adjustable fixtures. Adjustable fixtures are a new type of fixture developed for the limitations of general fixtures and special fixtures. Fixture. For workpieces of different types and sizes, it can be used only by adjusting or replacing other positioning elements and clamping parts on the original fixture. It is generally divided into general adjustable fixtures and group fixtures. The scope of the grip is larger than that of general fixtures. Anecdote is a special adjustable fixture, which is designed according to the principle of grouping and can process a group of similar Workpiece, so it has better economic effect when used in multi-variety, medium and small batch production.
4. Modular fixture
The fixture that uses standard combination of no parts and components, and is specially assembled for a certain closely related process of a certain workpiece, is called a complete fixture. The combination fixture is a modular fixture. The standard sign components have high software precision and wear resistance, and can be assembled into various fixtures. The fixture can be disassembled after use, and it is left to assemble a new fixture after cleaning. Since the use of modular fixtures can shorten the production preparation cycle, parts can be used repeatedly, and has the advantages of reducing special fixtures, so modular fixtures are available in single, medium and upper batches In multi-variety production and CNC machining, it is an economical fixture.
5. Assembling fixture
The fixture made of special standardized and serialized assembling parts and components is called assembling fixture. It has the advantages of modular fixtures, but it has higher precision, higher efficiency and compact structure than modular fixtures. Its base plate and clamping components Medium-sized cylinders are often included in the middle, and this type of fixture is more suitable for use on CNC machine tools.
In addition, the clamps can be divided into manual clamps, alarm clamps, clamps, gas-liquid augmentation clamps, electromagnetic clamps, and vacuum clamps according to the power source of the clamping.
