Description
Technical field
The present invention relates to tooling and fixture technical field, and in particular to a kind of no waste mine lightweight needle thorn fixture.
Background technique
Occur more and more meeting the multi-layer composite materials of intensity and lightweight demand simultaneously in modern industry material
Material is general to be sprayed etc. by manipulator fixture clamping stratiform material for the automation preparation process of multilayer materials
Combined processing.Polyurethane (PU) as the material for playing bonding, solidification in composite material, usually other stratified materials into
Row spraying covering.It is put by manipulator fixture clamping stratiform material between spraying and is sprayed on workbench.
It is hardened since PU has the characteristics that foaming, stronger adhesion, the clamping element on manipulator fixture is once stained with PU
Will foam because of PU can not move after being hardened, bad that protection done also because clamping element will do clamping movement.In order to avoid
PU can only increase material size, calculate dead size by product maximum rectangle exterior feature, to be also respectively enlarged in rectangular profile front-rear direction
Few 30mm, left and right directions respectively increases at least 105mm, so the size that feeds intake is more much larger than product, pressed waste material Zhan is always thrown
20% or more of doses, therefore generate excessive waste material.Waste disposal is costly, and pressed waste material can not divide due to being mixed with PU
From recycling, can only bundling post-paid ask garbage reclamation company to handle, processing cost is high；Waste material causes artificial and space waste,
A large amount of waste material needs special messenger's bundling, occupies factory floor space, influences beauty.
In addition, manipulator load used at present is limited, and has been all made of steel production plus manipulator fixture, meeting
Substantially clamp functionally, if be further added by adjust cantilever span away from mechanism, fixture is with regard to overweight.Based on this point, make at present
Fixture does not do such design, can not just adjust the amplitude of clamping material yet.Due to the size very much not phase of each product
Together, it is impossible to every kind of product all does a secondary proprietary fixture, so these big and small products can only common fixture, in order to put up with
Fixture causes bigger material waste.
Further more, existing manipulator clamp structure is rotary motion folding, intermediate plate during fixture decline when automatic material taking
It is often pressed onto material edge, when intermediate plate is closed such as material is not between two intermediate plates of manipulator, will lead to and drops off, and needs tight
It is anxious to brake blowing again, waste processing operation time.
For the above technical issues, need it is a kind of be suitable for PU spraying process, using lightweighting materials and structure, without spray
Apply the fixture of waste of material.
