Description

A kind of clamping localization method and device

Technical field

The invention belongs to mechanical manufacturing field, particularly a kind of clamping localization method and device of machining.

Background technology

Aviation casing processing at present generally all is to adopt rough turn, half finish turning, finish turning and bore technology such as boring and milling, complex procedures, and casing is of a great variety, diameter is different with wall thickness, cause used special tooling quantity more, majority adopted the corresponding frock clamps of procedures in the frock design in the past, and the corresponding part of frock clamp influences the reduction of enterprise's production cost and the raising of tool management efficient.

Application quick-clamping, accurate location technology are carried out the frock design, classify according to part to be processed resemble process, size proximity, make frock realize that standardization, seriation, generalization are the effective ways that improves working (machining) efficiency, can guarantee the part processing quality simultaneously.

Summary of the invention

The object of the invention is to provide a kind of clamping localization method.

For achieving the above object, the invention provides following technical scheme:

A kind of clamping and positioning device, comprise standard component and a discoidal metab, the base home position is provided with a circular central locating hole, four screws that are connected with lathe evenly distribute on the base, to radial direction n T-slot outwards is set along disc centre, T type groove is a circular groove near center of circle direction one end, arranges on the T type groove and passes through bolting during clamping parts by locating piece and the pressing plate that is complementary.

A kind of clamping localization method uses described clamping and positioning device, at first device pedestal is installed on the lathe centering; The choice criteria part guarantees that standard component size B is corresponding with part location dimension to be processed then, standard component is had alignment pin one end insert in the centre hole of base; Be that the locating piece position is determined in the center of circle again with the centre hole of base,, select locating piece quantity according to elements such as design of part to be processed, size and surpluses; Utilize fastening locating piece of connecting bolt and clamping platen at last, finish clamping, carry out part processing.

The invention has the beneficial effects as follows, can effectively reduce clamping frock quantity and centering time, shorten and produce the preparatory period, enhance productivity; Can make frock simplicity of design, convenient mounting and clamping, reduction labor strength; Low cost of manufacture, applied range.
