High-efficient modular fixture for processing part

Abstract

The invention relates to a group of clamps used for part processing, mainly consisting of a basic part and an adjustable part; wherein, the basic part comprises a clamping body (1) and transmission clamping parts (2, 3); the adjustable part consists of replaceable parts (4, 6) and an elastic expanding part (5); during the part processing, each dimension group of the part is provided with a group of corresponding replaceable parts. When parts of different dimension groups are processed, replaceable parts (4, 6) are all needed to be replaced; but in the same dimension group, only elastic expanding part (5) of corresponding dimension is needed to be replaced for the workpiece of difference positioning aperture; the clamp can shorten the design and manufacture time of normal clamp, saves the material and reduces the production cost.

Description

technical field [0001] The invention relates to a set of fixtures used for part processing, which belongs to the field of machine tool processing. Background technique [0002] Currently the most commonly used clamps in production are general clamps (eg CN200320131267.1) and special clamps (eg CN200410025697.4), each of which has its own strengths. Although the application of general-purpose fixtures is the most common, it is most suitable for single-piece production methods such as new product development, tool manufacturing, machine repair, and heavy-duty, complete sets of special equipment manufacturing. Various new parts can be put into production without increasing the cost of fixtures, but the application of this fixture in processing It needs marking and trial cutting, and the efficiency is very low. Although the special fixture is the product of mass production, which can improve efficiency and benefit, it requires a faster preparation cycle and higher fixture costs...

Although the application of general-purpose fixtures is the most common, it is most suitable for single-piece production methods such as new product development, tool manufacturing, machine repair, and heavy-duty, complete sets of special equipment manufacturing. Various new parts can be put into production without increasing the cost of fixtures, but the application of this fixture in processing Line marking and trial cutting are required, and the efficiency is very low

Although the special fixture is the product of mass production, which can improve efficiency and benefit, it requires a faster preparation cycle and higher fixture costs, and it is designed and manufactured according to the specific process of a specific part

Once the product is replaced or the part drawing is modified, a large number of special fixtures means scrapping
