Specific embodiment
In order to be illustrated more clearly that this utility model, this utility model is done further with reference to preferred embodiment
It is bright.It will be appreciated by those skilled in the art that specifically described content is illustrative and be not restrictive below, should not be with this
Limit protection domain of the present utility model.
Embodiment
As Figure 1-5, be novel expansion shaft grasping mechanism of the present utility model entirety and partial structural diagram.Should
Novel expansion shaft grasping mechanism is mainly made up of following part：Cylinder 1, floating connection block 2, the guide pillar 4, four of holding pad 3, four
Guide pin bushing 5, handgrip base plate 6, main axis of dilatation 7, and expansion shaft pressuring plate 8.Cylinder 1 is screwed on handgrip base plate 6, cylinder 1
Piston rod is connected on floating connection block 2；Holding pad 3 is screwed on floating connection block 2, and is connected with guide pillar 4；Grab
At hand plate 6 is screwed with expansion shaft pressuring plate 8, and is connected with guide pin bushing 5；Some main axis of dilatations 7 are kept off by expanding shaft pressuring plate 8
Firmly, and logical handgrip base plate 6 and holding pad 3 are worn；Main axis of dilatation 7 has elastic expansion head, and the elastic expansion head can be inserted into and wait to capture
In part.
Cylinder 1 is used for providing power for mechanism.Floating connection block 2 is used for essence when ensureing that holding pad 3 is connected with cylinder 1
Degree, causes cooperation center nurse a grievance phenomenon so as to avoid the occurrence of mismachining tolerance.Arrange holding pad 3 to be used for ensureing that handware is stably imbedded
Mould, it is to avoid unstability occur because handware profile is uneven, while holding pad 3 can play de- material effect, makes main axis of dilatation 7
Depart from handware 9, and push down handware 9 in feeding, enable the stable feeding of main axis of dilatation 7, so as to ensure that integrated tooling is stable
Property.Guide pillar 4 and guide pin bushing 5 coordinate, and mainly play the guiding role, and its quality of fit is high, and stability is strong.Arrange above each two guide pillar 4
There is guide pillar baffle plate 10, to ensure double guide pillar synchronizations and stable motion, while and playing hard position-limiting action under mechanism kinematic.Handgrip
It is hard spacing that the mainly mechanism of base plate 6 moves upwards, plays protection cylinder 2 and mechanism, while and 7 times gears works of main axis of dilatation
With being additionally to provide fixed support for other parts.Expansion shaft pressuring plate 8 mainly plays the effect of 7 gear of main axis of dilatation, makes multiple
Main axis of dilatation 7 stablizes spacing, while it can protect 7 class fit part of main axis of dilatation to reduce motion, it is ensured that good accuracy is positioned, and is also risen
To the effect of transmission power.
In a preferred embodiment, main axis of dilatation 7 includes rear end 71 and front end 72, and the head of front end 72 is carved and is provided with cross
Shape groove 73, forms elastic expansion head.The simple shape of the main axis of dilatation 7, small volume are convenient to process.The setting of cross bath makes
The head of main axis of dilatation 7 can produce certain elastic deformation.Rear end 71 is solid rear end, is provided with step 74 with 72 junction of front end.It is excellent
Selection of land, the apical head of cross bath 73 are provided with chamfering 75, arrange chamfering 75 and head is more easy to handware hole contract.Can
To understand, be able to can scribe in the head of main axis of dilatation 7 can arbitrarily make the shape of the certain deformation of head generation.It is preferable to carry out at one
In mode, main axis of dilatation 7 is overall to be made using Elastic Steel material, and the elastic deformability of such main axis of dilatation 7 is higher.
The novel expansion shaft grasping mechanism can be used to capture the product arbitrarily with the elastic expansion head that can be inserted into main axis of dilatation 7
In, it is particularly suited for handware crawl.At the hole by handware 9, the head of main axis of dilatation 7 is squeezed to hole contract, from
And pierce in the hole of handware 9, meanwhile, produce outside thrust in head, make handware 9 firmly close-fitting together, so as to reality
Existing pickup purpose.The diameter of the head of main axis of dilatation 7 can be according to needing to arrange, and most I is 1.6mm, that is to say, that the main axis of dilatation can
Minimum bore dia for capturing handware is not less than 1.5mm, and use range is quite varied.By handgrip base plate 6, holding pad 3,
Guide pillar 4, guide pin bushing 5, the restriction of the expansion combination of shaft pressuring plate 8, the impulse stroke of main axis of dilatation 7 are smaller, the protuberance through after handware
It is only 0.5-1mm to divide.
In a main axis of dilatation grasping mechanism, multiple main axis of dilatations 7 can be set, crawl high precision, stability can be so made
It is good.Additionally, according to needing, same product can be captured with the multiple main axis of dilatation grasping mechanisms of first use.
Cylinder 1 is power source, and can be arbitrarily can be used as the cylinder of power source, the tool at this to cylinder 1 in prior art
Body building block is not repeated, for example, single-piston rod double-acting cylinder, its power connection can be used to be divided into piston and piston
Bar, cylinder 1 connect piston rod, piston rod connection floating connection block 2 by piston.Floating connection block 2 is used for solving center
And precision problem, commercial standard part can be used, also can designed, designed, a contiguous block is for example set, its 5 degree of freedom are limited, only
Stay 1 degree of freedom.
The installation steps of novel expansion shaft grasping mechanism of the present utility model are briefly described：Main axis of dilatation 7 is penetrated
Handgrip base plate 6, press-fits expansion shaft pressuring plate 8 thereon, and handgrip base plate 6 is screwed with expansion shaft pressuring plate 8, afterwards by cylinder
1 is screwed on handgrip base plate 6, arranges floating connection block 2 in cylinder barrel one end, then that holding pad 3 is solid by screw
It is scheduled on the opposite side of floating connection block 2, guide pillar 4 is connected with holding pad 3, is finally putting into guide pin bushing 5 and is connected with handgrip base plate 6,
Guide pillar 4 and guide pin bushing 5 are engaged, and complete to install.During use, main axis of dilatation 7 is made to pass through elastic expansion head by controlling the motion of cylinder 1
Shrink and carry out pick-and-place handware 9.
Novel expansion shaft grasping mechanism of the present utility model is cooperated by multiple parts so that positioning precision is high, surely
It is qualitative good, can increase product yield, improve device efficiency, and by elastic deformation mode realizing the crawl to handware product
Or unclasp, crawl adaptability is wider, is not limited by handware structure and profile, die space.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate this utility model example, and
It is not the restriction to embodiment of the present utility model, for those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms, all of embodiment cannot be exhaustive here,
It is every belong to the technical solution of the utility model it is extended obvious change or change still in of the present utility model
The row of protection domain.
