Function of Fixture

In the process of processing, to reduce the machining error, improve the work efficiency, will use fixture for auxiliary processing production.

Fixture refers to the mechanical manufacturing process used to fix the processing objects, get it in the right place, to receive construction or inspection.

Fixture usually by positioning elements (make sure the workpiece in the fixture in the correct location), clamping device, tool setting guide element (determine the relative position of tool and workpiece or guidance tool direction), indexing mechanism (parts in an installation can complete several station processing, there are rotary indexing mechanism and linear motion indexing mechanism), connected components and clamp part (fixture base), etc.

Fixture plays an important role in machine tool work, no matter processing equipment, or choice of processing program is very important. In the mass production process, in order to improve the qualification rate and production efficiency of the parts, we can use special fixture.
Different machine tools use fixture are not the same, lathe fixture, drilling machine fixture, grinding machine fixture, gear fixture, etc., there are manual fixture, pneumatic fixture, magnetic fixture and so on.

– With the machine tool fixture clamping workpiece, can accurately determine the relative position between the workpiece and the tool, the machine tool, can ensure the machining accuracy.

– Machine tool fixture can locate and clamp the workpiece quickly, which can reduce the auxiliary time and improve the production efficiency.

– Machine tool fixture adopts mechanical, pneumatic and hydraulic clamping device, which can reduce the labor intensity of workers.

– Use the machine tool fixture, can expand the scope of the machine tool processing, for example, in the lathe or drilling machine boring die can replace the boring machine boring, so that the lathe, drilling machine has boring machine function.
