Introduction To Common Fixture Types

DALIAN, China - Dec. 5, 2022 - PRLog -- The fixture is usually composed of positioning element (to determine the correct position of the workpiece in the fixture), clamping device, tool setting guide element (to determine the relative position of the tool and the workpiece or guide the direction of the tool), indexing device (to enable the workpiece to complete the processing of several stations in a single installation, there are two types of rotary indexing device and linear moving indexing device), connecting element and clamp (fixture base).

Fixture Types Can Be Divided Into:

① Universal fixture.

For example, machine vises, chucks, suction cups, dividing heads and rotary workbenches are very versatile and can better adapt to the transformation of processing procedures and processing objects. Their structures have been finalized, and their dimensions and specifications have been serialized. Most of them have become a standard accessory of machine tools.

② Special fixture.

It is specially designed and manufactured for the clamping needs of certain product parts in a certain process. The service object is specific and highly targeted. Generally, it is designed by the product manufacturer itself. Commonly used are lathe jigs, milling machine jigs, jigs (machine tool jigs for guiding the cutter to drill or ream holes on the workpiece), boring dies (machine tool jigs for guiding the boring cutter bar to bore holes on the workpiece) and traveling jigs (mobile jigs for automatic lines of modular machine tools).

③ Adjustable clamp.

A special fixture for replacing or adjusting elements.

④ Modular fixture.

The fixture consists of standardized components with different shapes, specifications and uses, which is suitable for trial production of new products, single piece, small batch production and temporary tasks where products are often replaced.

In addition to vises, chucks, indexing heads and rotary worktables, there is a more common tool handle. Generally speaking, when the word tool clamp appears at the same time, most of the clamps refer to the tool handle.
