Description
Technical field
The utility model is related to a kind of fixture, more particularly to a kind of long bar anti-dumping fixture, in mechanical processing process
In, the long bar with greater depth direction size is clamped and fixed, belongs to machining technology field.
Background technology
In all kinds of workpiece process, fixture plays highly important effect, fixture mainly workpiece is played clamping and
Fixed effect.Workpiece for some shapes is, it is necessary to design special fixture.Such as：Length with greater depth direction size
Bar, common fixture, due to only having holding station, during clamping, long bar is easily tilted, under the influence of one
The progress of manufacturing procedure is walked, increases the defect ware rate of Product processing.In the prior art, also there are some sides for relying on multiple spot to fix
Formula, is clamped to long bar, still, due to being arranged fixture power, multiple fixing points often focus on together, for
Longer bar can not be fixed effectively.It is applied to long bar therefore, it is necessary to design one kind, prevents its inclined fixture.
Utility model content
The utility model is in the prior art, clamping the technology that effectively it can not be fixed for the fixture of long bar
Problem carries out good fixation and clamping to long bar there is provided a kind of long bar anti-dumping fixture.
Therefore, the utility model uses following technical scheme：
A kind of long bar anti-dumping fixture, including clamping limb and the power set for driving the clamping limb action, its feature exist
In：The clamping limb in setting over the ground, and two pairs of clamping limb one holding stations of formation, every a pair of clamping limbs set dynamic dress
Put, clamping limb makees relative or move toward one another in the presence of power set, the V-arrangement caved in the medial surface formation of each clamping limb
Clamping face；The holding station has two, and two holding stations have difference in height in vertical direction.
The long bar with greater depth direction size is clamped and fixed using a pair of clamping limbs, can be preferably
Long bar is clamped and fixed；V-arrangement clamping face can feel relieved to circular long bar, so that preferably to circle
The long bar of outer surface is fixed, and prevents that it from rocking；Multiple holding stations can once complete the clamping of more than one piece workpiece, improve effect
Rate；There is difference in height between multiple holding stations, interfering during clipping operation can be prevented, efficiency is improved.
Further, the difference in height L3 of two holding stations in vertical direction is two couples clamping in a holding station
Arm in vertical direction apart from 1st/1st to two/5th of L1.Interfering during clipping operation is prevented, is carried
High efficiency.
Further, two pairs of clamping limbs in a holding station in vertical direction apart from L1 be long bar section chi
5 to 7 times of very little L2.The setting of this spacing, can preferably fix long bar, prevent that it from rocking.
Further, the clamping limb includes body and the rack structure vertical with body, the tooth bar of a pair of clamping limbs
It is engaged between structure on a gear, the clamping arm body that the power set are disposed therein.
Further, the width D 1 of the V-arrangement clamping face opening is 1 to three/2nd point of long bar sectional dimension L2
Two, the angle β on V-arrangement clamping face both sides is 130-160 degree.It preferably can feel relieved and fix long bar.
Further, the length L4 of the clamping limb is two to four times of long bar sectional dimension L2.It is easy to clamping, prevents
Interfering between clamping limb and processing equipment.
Further, the power set are cylinder, oil cylinder or servomotor.Convenient material drawing, effect is good.
To sum up, long bar anti-dumping fixture of the present utility model, by a pair of clamping limbs to greater depth direction size
Long bar clamped and fixed, there is good clamping effect, efficiency high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is front view of the present utility model；
Fig. 3 is top view of the present utility model；
Fig. 4 is side view of the present utility model；
Fig. 5 is the structural representation of clamping limb of the present utility model；
In figure, 1 is clamping limb, and 11 be body, and 12 be rack structure, and 13 be gear；2 be power set, and 3 be that V-arrangement is clamped
Face, 100 be holding station, and 101 be long bar.
Embodiment
In order that those skilled in the art are better understood from the utility model scheme, it is real below in conjunction with the utility model
The accompanying drawing in example is applied, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As Figure 1-5, long bar anti-dumping fixture of the present utility model, includes for clamping long bar 101：Clamping limb 1
With the power set 2 for driving the clamping limb action, clamping limb 1 in setting over the ground, and two pairs of clamping limbs form a holding stations
100, every a pair of clamping limbs are provided with power set, and two clamping limbs make relative or move toward one another in the presence of power set,
So as to close or open clamping limb, the V-arrangement clamping face 3 caved in the medial surface formation of each clamping limb；The holding station
100 have two, and two holding stations have difference in height in vertical direction；Specifically, as shown in Fig. 2 two clamping works
100 difference in height L3 in vertical direction of position be two pairs of clamping limbs 1 in a holding station in vertical direction apart from L1
1/1st to two/5th, in the present embodiment, L3 is one of three parts of L1.The design can be prevented in clipping operation process
In interfere, improve efficiency；Simultaneously, it is ensured that the stability of clamping.
Two pairs of clamping limbs in one holding station in vertical direction apart from L1 be long bar sectional dimension L2 5 to
7 times.This design can preferably fix long bar, prevent that it from rocking along its length.
As a kind of specific structure of clamping limb, clamping limb 1 includes body 11 and the rack structure vertical with body
12, a gear 13, the clamping that the power set 2 are disposed therein are engaged between the rack structure of a pair of clamping limbs
On arm body.So, when power set are acted, and are acted on one of clamping arm body, gear and tooth bar are passed through
Transmission, makes a pair of clamping limbs relative or move toward one another, so as to close or open the clamping limb, workpiece is clamped and taken
Put.
In order to obtain superior technique effect, the width D 1 that the V-arrangement clamping face 3 is open is long bar sectional dimension L2's
2/1sts to three/2nd, the angle β on V-arrangement clamping face both sides is 130-160 degree.This structure preferably can feel relieved and fix length
Bar.
In order to obtain superior technique effect, the length L4 of clamping limb is two to four times of long bar sectional dimension L2.This
Structure is easy to clamping, prevents interfering between clamping limb and processing equipment.
The power set are cylinder, oil cylinder or servomotor.Convenient material drawing, control effect is good.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, should all belong to the scope of the utility model protection.
