Detailed description of the invention
Below in conjunction with the accompanying drawings the power pin removal of the present invention is described in detail.
As it is shown in figure 1, the power pin removal of the present invention includes location-plate 10, slip pin pulling out device 20, power set 30, sliding
Dynamic pin pulling out device 20 is between location-plate 10 and power set 30, and location-plate 10 is connected to power by four pillars 40 and fills
Put on 30.
As in figure 2 it is shown, have rectangular opening 11 and long and narrow opening 12 on location-plate 10, both communicate, the extension side of opening 12
To the hole wall being perpendicular to rectangular opening 11.Rectangular opening 11 makes alignment pin 100 can be stretched into by it in slip pin pulling out device 20；
Opening 12 person convenient to operate takes out the alignment pin 100 being pulled out.A pair rectangular recess 13 is also had on the lower surface of location-plate 10,
Two rectangular recess 13 extend towards both sides from two longer sidewalls of rectangular opening 11 respectively.
Power set 30 are pneumatic mode, are embodied in a double dynamic single shaft standard type cylinder, and this cylinder 30 has piston rod
31.Those skilled in the art should be it is readily conceivable that power set can also use other patterns, such as electric model etc..
As shown in Figure 3, Figure 4, slip pin pulling out device 20 includes pull bar 21, installing plate 22, a pair support seat 23, a pair folder
Pawl 24, spring 25 and top board 26.Pull bar 21 has an axle ring 210 being located therein portion, one end of pull bar 21 and cylinder
The piston rod 31 of 30 connects, and installing plate 22 is socketed on pull bar 21.
A pair support seat 23 is arranged on installing plate 22, and is oppositely disposed at the both sides of pull bar 21.Specifically, support
The bottom of seat 23 has installing hole, and the two ends of installing plate 22 also have installing hole, utilizes the installation elements such as bolt will support seat 23
It is fixed on installing plate 22.Each support seat 23 includes top 231 and bottom 232, and top 231 tilts towards pull bar 21,
It has an angle of inclination relative to bottom 232；Top 231 includes two arms 233 being parallel to each other, two arms 233 it
Between there is interval 234, each arm 233 has mounting hole 235 on its incline direction, two arms 233 of each support seat 23
On mounting hole 235 position relative.
Spring 25 is socketed on pull bar 21, and the lower end of spring 25 is supported by the axle ring 210 of pull bar 21, upper end roof supporting 26.
The two ends of top board 26 lay respectively at two support seat 23 tops 231 intervals 234 in, and can interval 234 on downslide
Dynamic.A pair jaw 24 is supported on the two ends of top board 26 respectively, and is positioned partially in interval 234.Each jaw 24
On be installed with oval pin 241 and short cylindrical pin 242, long and short straight pin 241,242 crosses jaw 24, and they
Two ends stretch out from jaw 24, coordinate with two mounting holes 234 on each support seat 23 respectively.The two of oval pin 241
Holding and stretch out mounting hole 234, and be positioned at the lower section of the rectangular recess 13 of location-plate 10, it is oval that rectangular recess 13 can play restriction
Pin 241 movement travel upwards.The alloy sword pawl 243 made equipped with Hardmetal materials on the opposite face of two jaw 24 upper ends,
Its head wears into keen edge, fors facilitate gripping by alignment pin 100.
Two outsides of one of them supporting seat 23 are provided with long adjustment frame 51, and another outside supporting seat 23 is provided with the whole frame of minor
52, long and short adjustment frame 51,52 is U-shaped, and the long two legs adjusting frame 51 has screwed hole, the whole frame of minor 52
Having through screwed hole on two legs, screw 53 is through the screwed hole on the whole frame of minor 52, then stretches into the long spiral shell adjusting frame 51
In pit, thus long and short adjustment frame 51,52 is coupled together.On the one hand arranging of long and short adjustment frame 51,52 add
Support the rigidity of seat 23；On the other hand, by fine-tuning two distances supported between seat 23 of the degree of tightening of regulation screw 53,
Thus finely tune and open distance when two jaws 24 are in open configuration so that the alignment pin that the power pin removal of the present invention can be chosen
Size allow in less size range, have variation.
The size of the alignment pin that the power pin removal of the present invention can be chosen can also have variation in bigger size range, by changing
Become the distance between the installing hole at installing plate 22 two ends, the distance between two support seats 23 can be changed, so that power pulls out
Pin device can be chosen the alignment pin of various sizes.
The process of pulling pin of power pin removal of the present invention is described below in conjunction with Fig. 5 a～5c.
As shown in Figure 5 a, power pin removal is in original state.In an initial condition, the piston rod 31 of cylinder 30 is in elongation
State, pull bar 21 and the installing plate 22 being mounted thereon and support seat 23 are withstood on higher position by piston rod 31, folder
The motion upwards of oval pin 241 on pawl 24 is limited by rectangular recess 13 on location-plate 10 and downward compression spring 25,
Oval pin 241 is positioned at the bottom of mounting hole 235, and now, the distance between two jaws 24 is maximum, is in open configuration,
Alignment pin 100 can be put into two jaws 24 through the rectangular opening 11 of location-plate 10.
After alignment pin 100 is put between two jaws 24, pinching action implemented by power pin removal.As shown in Figure 5 b, cylinder 30
Piston rod 31 bounce back, drive pull bar 21 and support seat 23 move downward, now spring 25 is released, by top board 26
Upwardly jaw 24, the long and short straight pin 241,242 on jaw 24 moves upward along mounting hole 235, jaw 24
Moving upward relative to supporting seat 23, under the guide effect of mounting hole 235, the distance between two jaws 24 reduces, thus
Clamping and positioning pin 100.
After alignment pin 100 is clamped, power pin removal is implemented to choose action.As shown in Figure 5 c, the piston rod 31 of cylinder 30
Continue retraction, drive pull bar 21 and whole slip pin pulling out device 20 to move downward, thus slip pin pulling out device 20 will be clamped at
Alignment pin 100 extract.
Disclosed power pin removal assembly is not limited to representated by the content described in embodiment of above and accompanying drawing
Structure.Obviously changed what the shape of wherein component and position made, substitute or revise on the basis of the present invention,
All within the scope of protection of present invention.
