Structure, the bottom of the movable support pin is connected by first rotating shaft with the top of I type connecting rods, and the bottom of the H types connecting rod leads to
Cross the second rotating shaft to be fixed on connecting seat, bottom, the top of H type connecting rods of the I types connecting rod pass through the 3rd rotating shaft and Y type connecting rods
Axle connects, and the Y types connecting rod makees stretching motion by cylinder driving, and the dead point limited block correspondence H type connecting rods are arranged at Y type connecting rods
Opposite side and the vertical states of H type connecting rods is carried out spacing.
It is a kind of preferred embodiment as the utility model, the bottom of movable support pin be through inverted U slot structure,
The both sides of inverted U groove, which are correspondingly provided with the top of through hole, the I types connecting rod, to be inserted into inverted U groove and by first rotating shaft and work
Dynamic support bearing pin connects.
As the utility model another preferred embodiment, bushing, the movable support are provided with the mounting seat
Pin is assemblied in mounting seat through bushing.
As the further improvement to above-mentioned embodiment, the bushing is copper sheathing.
As the utility model another preferred embodiment, the dead point limited block is set to two and is fixed on company
On fishplate bar, top two-arm of two dead point limited blocks respectively with H type connecting rods is corresponding, and the connecting plate is vertically installed at connecting seat
On.
As the further improvement to above-mentioned embodiment, the dead point limited block is provided with adjust pad.
As the utility model another preferred embodiment, the cylinder is arranged on connecting seat.
Beneficial effect
In the utility model, movable support pin is alignment pin and the integrally formed structure of locating piece, can accurately be protected
Demonstrate,prove the perpendicularity of positioning product datum hole and reference plane；Alignment pin is driven by connecting rod dead point position-limit mechanism using cylinder so that
The each working condition of mechanism can be just spacing in dead-centre position, so as to ensure mechanism position stability and reliability and repetition
Positioning precision；There is the movable support pin of the mechanism larger moving back to sell journey, conveniently move back pin pickup, in the big arc-welding of welding deformation
There is stronger practicality in production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
A kind of two-sided biradical quasi- integral type self-locking positioning mechanism as shown in Figure 1, including movable support pin 1, mounting seat 2,
Connecting seat 3, I types connecting rod 4, dead point limited block 5, H types connecting rod 6, Y types connecting rod 7 and cylinder 8.
Mounting seat 2 is fixed on connecting seat 3, and bushing 12 made of copper, movable support pin 1 are cased with the mounting hole of mounting seat 2
Telescopically it is assemblied in mounting seat 2 through bushing 12.Movable support pin 1 be alignment pin and the integrally formed structure of locating piece,
