The invention belongs to part machinery processing technique field, it is related to a kind of part vacuum adsorption fixture and clamping method.The present invention connects a set of dedicated suction jig by vacuum pump, and part positioning surface is close to the stomata of chucking surface, is constantly evacuated by vacuum pump and realizes clamp body persistently sucking to part.The magnetic-adsorption problems of non-magnetic materials such as this method effective solution copper, aluminium, stainless steel and some structure is complicated, common tooling, which can not be clamped, clamps easily-deformable problem with thin-walled parts, this method is to step up to provide a kind of completely new thinking for part is fixed to one kind of conventional method of clamping supplement and perfect very well.
Description
Technical field
The invention belongs to part machinery processing technique field, it is related to a kind of part vacuum adsorption fixture and clamping method.
Background technique
Currently, one is carry out machine to part by general and Special frock device there are mainly two types of parts fixation methods
Tool clamping, one is the magnetic force generated using magnetic suction disc to carry out absorption compression to part.But in reality production, Yi Xieling
Part is since structure is complicated, and common tooling can not be clamped directly or mechanical grip is easy to bring deformation, and such as copper, aluminium, stainless
The non-magnetic materials such as steel can not be fixed directly by the magnetic-adsorption that magnetic suction disc generates, these undoubtedly will increase the difficulty of mechanical processing technique
Degree and complexity, and a series of overproof problem of part deformations can be brought.
Summary of the invention
The purpose of the present invention: being directed to above-mentioned existing processing problems, and the present invention provides a kind of part vacuum suction clamping method,
It is poor using part positioning surface upper and lower air pressure by vacuum pump continuous air extraction, realize that atmosphere is fixed the duration of part.It should
Method can the magnetic-adsorption problem of non-magnetic materials such as effective solution copper, aluminium, stainless steel and it is some structure is complicated, unskilled labor
Dress, which can not be clamped, clamps easily-deformable problem with thin-walled parts.
Technical solution of the present invention:
To achieve the goals above, the technical solution of the invention patent is that a kind of part vacuum adsorption fixture, feature exists
In, including pedestal 5, cover board 6 and appendix 2, the pedestal are barrel-like structure, side wall is equipped with mounting hole, and appendix 2 is mounted on
In mounting hole, cover board 6 is sealingly mounted on pedestal 5, and cover board 6 is equipped with multiple aspirating holes.
The diameter of aspirating hole on the cover board 6 is greater than 2mm.
Aspirating hole on the cover board 6 is symmetrical.
The aspirating hole should not exceed part 4 and the practical binding face of cover board 6.
The suction jig 3 is connect by appendix 2 with vacuum pump 1.
The inner cavity of the aspirating hole and pedestal 5 penetrates through.
The 6 top surface plane degree of cover board is not more than 0.01mm.
A kind of part vacuum suction clamping method, comprising the following steps:
1) suction jig 3 is connected on vacuum pump 1 by pipeline 2
2) part 4 is placed on the positioning surface of suction jig 3；
3) vacuum pump 1 is opened, part 4 is tightly adsorbed on 3 cover board of suction jig, 6 upper surface under air pressure effect
It is upper:
4) part 4 is processed；
5) vacuum pump 1 after processing is completed, is closed, part 4 is removed.
6 upper surface of cover board is bonded with 4 positioning surface of part.
Beneficial effects of the present invention: the present invention connects a set of dedicated suction jig by vacuum pump, and part positioning surface is close to
The stomata of chucking surface is constantly evacuated by vacuum pump and realizes clamp body persistently sucking to part.This method effectively solves
Determined the non-magnetic materials such as copper, aluminium, stainless steel magnetic-adsorption problem and it is some structure is complicated, common tooling can not clamp and
Thin-walled parts clamp easily-deformable problem, this method be to one kind of conventional method of clamping supplement and perfect very well, it is solid for part
Step up to provide a kind of completely new thinking calmly.
