Abstract
The present invention relates to a kind of gripping finger for axial workpiece clamping, axial workpiece clamping rear end face can be made to be adjacent to location end face, it is ensured that location is reliable。In this gripping finger, gas pawl is by compressing air by Air Valve Control folding, and gripping finger bar one end is mounted on gas pawl by screw, and there is the V-shaped groove of processing in the other end portion of gripping finger bar；Rubber cushion and fixing thin slice is fixed respectively above V-shaped groove；Rubber cushion also determines V-shaped groove, and when being fixed on gripping finger bar, rubber cushion exposes at V-shaped groove place；When adopting this kind of gripping finger clamping axial workpiece, rubber cushion deforms due to stress, can be deformed by fixing sheet extrusion simultaneously；Due to the existence of deformation, axial workpiece can be pushed up, enable the end face of axial workpiece to be adjacent to location end face, reach the purpose of end face location。
Description
Technical field
The invention belongs to precision optical machinery field, relate to a kind of gripping finger for axial workpiece clamping, axial workpiece clamping rear end face can be made to be adjacent to location end face, it is ensured that location is reliable。
Background technology
When adopting gripping finger clamping axial workpiece, need in some cases it is carried out end face location, be adjacent to by end face and a certain parts end face of axial workpiece。But due to gripping finger accuracy of manufacture problem, and the shape by part itself is limit, tend not to enough be adjacent to location end face clamping rear axle class part end face through gripping finger, gap can be left therebetween, cause part orientation problem。Therefore, find a kind of simple possible and the clamp method of end face location can be reached, it is achieved the reliable retention of axial workpiece is necessary with location。
Summary of the invention
The technical problem to be solved in the present invention is a kind of clamp method for path axial workpiece, it is ensured that end face can reliably position。
Technical scheme is as follows:
This gripping finger is made up of gas pawl, gripping finger bar, rubber cushion, fixing thin slice。When adopting this gripping finger clamping axial workpiece, gripping finger bar does not contact with axial workpiece itself, and rubber cushion contacts with axial workpiece, is pushed to locating surface by part by the deformation of rubber cushion, reaches the purpose positioned by part end face。
The invention has the beneficial effects as follows: can make axial workpiece when held, it is necessary to fit tightly between face and the location end face of location, it is ensured that such part will not produce axial float in assembling process, it is ensured that assembly precision。
Accompanying drawing explanation
Fig. 1 is the gripping finger structure chart of the present invention。
Fig. 2 is gripping finger structural representation。
In figure: 1 gas pawl；2 gripping finger bars；3 rubber cushions；4 thin slices；5 location end faces；6 held axial workpieces；7 positioning discs；8 press-fit round platform。
Detailed description of the invention
The detailed description of the invention of patent of the present invention is described in detail below in conjunction with technical scheme and accompanying drawing。
As it is shown in figure 1, gas pawl 1 is by compressing air by Air Valve Control folding, gripping finger bar 2 is convex shape, and two gripping finger bar 2 one end are symmetrically fixed on gas pawl 1 by screw clearance holes, and the other end of gripping finger bar 2 fixes rubber cushion 3 and thin slice 4 successively；The V-shaped groove opposite position of two gripping finger bars 2 is for installing held axial workpiece 6；The inner side of rubber cushion 3 and thin slice 4 is provided with the relevant position of V-shaped groove and is provided with V-shaped groove；Rubber cushion 3 is at V-shaped groove place relative to the V-shaped groove width of gripping finger bar 2, and rubber cushion 3 protrudes；Held axial workpiece 6 is fixed on the end face 5 of location, and described location end face 5 is positioned at the center of positioning disc 7, and positioning disc 7 is provided with through hole, for press-fit round platform 8 and fix；Press-fit round platform 8 and also be provided with through hole。When adopting held axial workpiece 6, need to manually making held part end face be adjacent to location end face 5, now, rubber cushion 3 deforms due to stress, simultaneously can by thin slice 4 crimp；Due to the existence of deformation, held axial workpiece 6 can be pushed away to end face side, location, make the end face of held axial workpiece 6 can be adjacent to location end face 5, reach the purpose of end face location。Described thin slice is sheet metal。
Claims (2)
1., for a gripping finger for axial workpiece clamping, make axial workpiece clamping rear end face be adjacent to location end face, it is ensured that location is reliable, it is characterised in that:
Gas pawl is by compressing air by Air Valve Control folding, and gripping finger bar is convex shape, and two gripping finger bar one end are symmetrically fixed on gas pawl by screw clearance holes, and the other end of gripping finger bar fixes rubber cushion and thin slice successively；The V-shaped groove opposite position of two gripping finger bars is for installing held axial workpiece；The relevant position, inner side of rubber cushion (3) and thin slice (4) is provided with V-shaped groove；Rubber cushion is at V-shaped groove place relative to the V-shaped groove width of gripping finger bar, and rubber cushion protrudes；Held axial workpiece is fixed on the end face of location, and described location end face is positioned at the center of positioning disc, and positioning disc is provided with through hole, for press-fit round platform and fix；Press-fit round platform and also be provided with through hole；Held part end face is adjacent to location end face, and sheet extrusion is deformed by rubber cushion stress, and held axial workpiece pushes away to end face side, location, reaches end face location。
2. the gripping finger for axial workpiece clamping according to claim 1, it is characterised in that: described thin slice is sheet metal。
