Repeatable accuracy is high, and structure is reliable, cam-operated by rotary shaft, and positioning is quick, simple to operate.
According to technical scheme：A kind of rollback formula jacks flexibly positioned pin assemblies, it is characterised in that：Including
Pedestal, the endoporus upper end of pedestal are equipped with guide pin bushing, are slided in guide pin bushing endoporus and set alignment pin, alignment pin lower end is passed through in guide pin bushing
Hole, and stretched out from base bottom surface, the lower end shank that alignment pin stretches out pedestal sets contiguous block, and the first spring is arranged on alignment pin,
First spring upper end is held out against on guide pin bushing lower surface, and the first lower spring end is pressed on contiguous block, in the axial bore of alignment pin
Second spring is set, and second spring upper end is held out against at the top of alignment pin endoporus, and second spring lower end is pressed in the cell body of contiguous block
Bottom surface, base bottom surface are arranged with two pieces of connecting plates in parallel, and axis of rotation is arranged on the connecting plate, is fixed with rotating shaft convex
Wheel, cam are connected with contiguous block.
As a further improvement on the present invention, the guide pin bushing is fastenedly connected on pedestal by screw.
As a further improvement on the present invention, the end of the rotating shaft is connected with handle.
As a further improvement on the present invention, the side end face of cam one is spacing solid by the radial protrusion set in rotating shaft
Fixed, another side end face of cam is locked by locking nut.
The technical effects of the invention are that：Product structure of the present invention is simple, reasonable, can be effectively applicable to all kinds of cylinder bodies zero
The positioning of part end face inner bore, repeatable accuracy is high, and structure is reliable, cam-operated by rotary shaft, and positioning is quick, simple to operate.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is cam of the present invention and alignment pin mutual cooperation schematic diagram.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including alignment pin 1, guide pin bushing 2., pin 3, the first spring 4, second spring 5, contiguous block 6, cam 7, support
Seat 8, handle 9, rotating shaft 10, locking nut 11, pedestal 12, connecting plate 13, screw 14 etc..
As shown in Figure 1, 2, the present invention is that a kind of rollback formula jacks flexibly positioned pin assemblies, including pedestal 12, pedestal
12 endoporus upper end is equipped with guide pin bushing 2, is slided in the endoporus of guide pin bushing 2 and sets alignment pin 1, and the lower end of alignment pin 1 is passed through in guide pin bushing 2
Hole, and being stretched out from the bottom surface of pedestal 12, the lower end shank that alignment pin 1 stretches out pedestal 12 sets contiguous block 6, and the is arranged on alignment pin 1
One spring 4, the upper end of the first spring 4 are held out against on the lower surface of guide pin bushing 2, and the lower end of the first spring 4 is pressed on contiguous block 6, alignment pin 1
Axial bore in second spring 5 is set, the upper end of second spring 5 is held out against at the top of the endoporus of alignment pin 1,5 times side pressures of second spring
Tightly in the cell body bottom surface of contiguous block 6, the bottom surface of pedestal 12 is arranged with two pieces of connecting plates 13 in parallel, and rotating shaft 10 rotates and is arranged at the company
On fishplate bar 13, cam 7 is fixed with rotating shaft 10, cam 7 is connected with contiguous block 6.
Guide pin bushing 2 is fastenedly connected on pedestal 12 by screw 14.
The end of rotating shaft 10 is connected with handle 9.
For the side end face of cam 7 one by the spacing fixation of radial protrusion set in rotating shaft 10,7 another side end face of cam passes through lock
Tight nut 11 is locked.In concrete practice, in order to effectively be limited the stroke of alignment pin 1, along axle on alignment pin 1
To waist type groove is set, guide pin bushing 2 is provided with pin 3, and pin 3 is stretched into waist type groove.
Product of the present invention uses rollback formula climbing structure, alignment pin is lived about 1 with moving cam 7 by rotating shaft 10
It is dynamic, realize the positioning to cylinder body end face inner bore, spring force makes alignment pin 1 retract before feeding, avoids interference with, workpiece is well placed it
