Description
Technical field
It the utility model is related to technical field of automation in industry, and in particular to one kind has positioning, support and one-way buffer
The pin structure of function.
Background technology
In today that industrial automation is have swept the globe, automatic assembly line, intelligent expert decision-making, information-based big data etc.
Start to come among daily life.Under the trend of modern social development, industry integration is staggeredly collided with field to be occurred
It is more and more frequent, wherein automation, precision, diversified integrated equipment are increasingly favored be subject to society.Light industry by
In the product of its production and the environmental problem of manufacturing shop, major part, which all belongs to, gently loads small inertia field, in order to drop
Low design difficulty, the function module of most equipment manufacturer is all independent separate, therefore possesses multi-functional mechanical part
There is very big white space to need to fill up at home.
Need to use a kind of pin for meeting positioning function in Sheet Metal Forming Technology link, it is installed on bottom plate, generally and work
Location hole on part coordinates, and promotes pin by gravity or linear movement unit during positioning, guides the through hole of workpiece to be slipped to
So as to complete positioning function on pin.But the pin of the prior art only has positioning function, it is necessary to be completed by other mechanisms
The function of clamping is supported, and pin is metal material, intensity is higher, situations such as be easy to causeing workpiece collision, friction and scratch,
Cause product qualification rate relatively low.
Utility model content
In view of the problems of the existing technology, the utility model aim is to provide a kind of pin structure, and it is fixed not only to have
Bit function, also at the same time meet platform act on, facilitate workpiece positioned after compression precompressed, and with unidirectional linearity fortune
The function of dynamic buffering.
The technical scheme adopted by the utility model is that：A kind of pin structure, including positioning head and pin body, positioning head are used for
The positioning of workpiece, pin body are used to support and mounting pin rod structure.Supporting table is provided with the positioning head, is used to support work
With positioning head lower face center offers guide groove；The pin body upper surface is provided centrally with sliding with the guide groove
The guide post coordinated is moved, is arranged and has elastic component on the guide post, by the effect of flexible member pretightning force, guide post can be in guide groove
Interior slip, and there is certain cushion performance.
Preferably, the positioning head front end is provided with location division, and the location division is truncated cone-shaped, cone, polygonal cone
Or more side platform shape structures.Positioning head front end is positioned using the bootable workpiece through hole of this up-small and down-big structure, makes it
Easily matched with positioning head, reduce the difficulty of positioning.
Further as above-mentioned technical proposal is improved, and limiting gasket is also arranged with outside the guide post.Limiting gasket with
Pin body upper surface is bonded, and when guide post slides up and down in guide groove, is risen between supporting table lower face and pin body certain
Cushioning effect.
Further as above-mentioned technical proposal is improved, and the limiting gasket is made of elastic material.Preferably polyurethane
Or the material such as rubber.
Further as above-mentioned technical proposal is improved, and the pin body bottom is provided with installation screw thread, is easily installed solid
It is fixed.
The beneficial effects of the utility model are：Compared with prior art, a kind of pin structure provided by the utility model,
It is simple in structure, manufacture cost it is low, the design of positioning head and supporting table can be on the basis of positioning function be met, there is provided workpiece position
Support function afterwards, can form plate certain precompression, so as to preferably fix workpiece；Guide post, guide groove and elasticity member
The combination of part produces cushioning effect during workpiece guiding slides, and can protect workpiece surface to a certain extent, prevent from scratching
With the generation of collision situation.

Embodiment
It is the structure decomposition figure of preferred embodiment provided by the utility model as shown in Figure 1, with reference to figure 1, Fig. 2 and Fig. 3, sheet
A kind of pin structure of embodiment, is provided with supporting table 11 on the positioning head 1, plays a part of to support workpiece, the positioning
First 1 lower face center offers guide groove 12；2 upper surface of pin body is provided centrally with being slidably matched with the guide groove 12
Guide post 21, be arranged on the guide post 21 and have elastic component 3, limiting gasket 22, the spacing pad are also arranged with outside guide post 21
Circle 22 is bonded with 2 upper surface of pin body.In the present embodiment, it is preferred that flexible member 3 generally uses spring, and limiting gasket 22 is
Polyurethane or other materials with pooling feature are made；Spring is on guide post 21, between supporting table 11 and limiting gasket 22,
Its elastic effect can be more played, so that with certain cushion performance.
In the present embodiment, 1 front end of positioning head is provided with location division 13, and location division 13 is truncated cone-shaped, cone, polygonal cone
Or more side platform shape structures, the bootable workpiece through hole of the up-small and down-big structure are positioned, make it easier to match somebody with somebody with positioning head 1
