Utility model content
Technical problem to be solved in the utility model be for the background art device moment of couple it is not reciprocity, bias etc. is asked
Topic, the present invention provides a kind of link-type clamping devices, and which solve appearance apparent movement in traditional clamping device two sides is not right
Claim, weight is easy the problem of sliding in clamping process.
The utility model uses following technical scheme to solve above-mentioned technical problem
A kind of link-type clamping device includes fixed bracket, steering engine, the first rocking bar, the second rocking bar, the first clamping hand, the
Two clamping hands, crank；Wherein, the first clamping hand and the second clamping hand are oppositely arranged and connect with fixed holder pivots, the song
Handle and steering engine are sequentially connected, and first rocking bar and the second rocking bar connect with crank, the first clamping hand, the second clamping hand rotation respectively
It connects, the steering engine is fixed in the U-type groove of fixed bracket left end.
As a kind of further preferred scheme of link-type clamping device of the utility model, the link-type clamping device is
Manipulator finger-type, generally single crank double rocker mechanism, and crank is at a certain angle connected, the revolution provided by the steering engine
Movement driving crank, the first clamping hand, the angle that the shape of the second clamping hand has a common edge by two are 120oAlphabetical V group
At.
As a kind of further preferred scheme of link-type clamping device of the utility model, the first of link-type clamping device
Two are dispersed on rocking bar and the second rocking bar for adjusting the hole of clamping object volume.
As a kind of further preferred scheme of link-type clamping device of the utility model, it is provided on the fixed bracket
Two auxiliary supporting rods are equipped with symmetrical U-type groove on support bracket fastened left end frame.
As a kind of further preferred scheme of link-type clamping device of the utility model, hand, the second folder are clamped first
Hold the soft high friction-type polymer slid when being provided with one layer on the inside of hand for preventing crawl object.
The utility model compared with the prior art by using the above technical solution, has following technical effect that
The utility model becomes crank at certain by optimizing traditional single rocking bar double-crank mechanism
The connected single crank double rocker mechanism of angle, which reaches when solving two clamping hands movements, there is apparent asymmetry, causes object sliding
Fall the purpose of problem.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of the clamping cylindrical object of the utility model.
In figure: the fixed bracket of 1-, 2- steering engine, the first rocking bar of 3-, 4- first clamp hand, and 5- second clamps hand, and 6- second shakes
Bar, 7- crank.
Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawing:
In order to state that the purpose of the present invention, skill scheme and advantage more clearly, below by the example of specific implementation
Son and in conjunction with attached drawing, the present invention is described in further detail.Certainly, specific implementation example described herein only to
To explain the present invention, without limiting the present invention.In addition, technology involved in the embodiment of invention described below is special
Sign can be combined with each other as long as they do not conflict with each other.
This project provides a kind of novel link type clamping device, as shown in Figure 1, a kind of link-type described in the utility model
Clamping device clamps hand 5, crank comprising fixed bracket 1, steering engine 2, the first rocking bar 3, the second rocking bar 6, first clamping hand 4, second
7。
Wherein, the first clamping hand 4 and the second clamping hand 5 are oppositely arranged and are rotatablely connected with fixed bracket 1, the crank 7
It is sequentially connected with steering engine 2, first rocking bar 3 and the second rocking bar 6 clamp hand 4, second with crank 7, first respectively and clamp 5 turns of hand
Dynamic connection, the steering engine 2 are fixed in the U-type groove of fixed 1 left end of bracket.
The link-type clamping device is manipulator finger-type, generally single crank double rocker mechanism, and crank 7 is at certain
Angle is connected, and drives crank 7 by the rotary motion that the steering engine 2 provides, the first clamping hand 4, second clamps the shape of hand 5 by two
A angle for having a common edge is 120oAlphabetical V composition.
Be dispersed on the first rocking bar 3 and the second rocking bar 6 of link-type clamping device two for adjust clamping object volume
Hole.
It is provided with two auxiliary supporting rods on the fixed bracket 1, is equipped on the left end frame of fixed bracket 1 symmetrical
U-type groove.
It is slid when the inside that the first clamping hand 4, second clamps hand 5 is provided with one layer for preventing crawl object soft
The high friction-type polymer of property.
Working principle: when the steering engine is powered, the crank 7 in Fig. 1 is driven to rotate, crank rotation makes rocking bar make to carry out backswing
Dynamic, clamping hand completion steps up or unclamps product when the swing of rocking bar.
In order to enable the invention to the lesser cylindrical object of clamping dimension, by the adjustment hole being arranged on rocking bar, change is shaken
The length of bar is to reduce two opening angles for clamping hands.
In addition to guarantee smoothly to clamp object, the auxiliary holding device that the present invention is arranged on fixation bracket can be
