The specific embodiment

Below in conjunction with accompanying drawing, power pin removal of the present utility model is described in detail.

As shown in Figure 1, power pin removal of the present utility model comprises location-plate 10, slip pin pulling out device 20, power set 30, and slip pin pulling out device 20 is between location-plate 10 and power set 30, and location-plate 10 is connected on power set 30 by four pillars 40.

As shown in Figure 2, have rectangular opening 11 and long and narrow opening 12 on location-plate 10, both communicate, and the bearing of trend of opening 12 is perpendicular to the hole wall of rectangular opening 11.Rectangular opening 11 can stretch in slip pin pulling out device 20 by it alignment pin 100; Opening 12 convenient operation persons take out the alignment pin 100 being pulled out.On the lower surface of location-plate 10, also having 13, two rectangular recess 13 of a pair of rectangular recess extends towards both sides from two of rectangular opening 11 longer sidewalls respectively.

Power set 30 are pneumatic mode, are embodied in a two moving single shaft standard type cylinder, and this cylinder 30 has piston rod 31.Those skilled in the art should be easy to expect, power set also can adopt other patterns, such as electric model etc.

As shown in Figure 3, Figure 4, slip pin pulling out device 20 comprises pull bar 21, installing plate 22, a pair of supporting seat 23, a pair of jaw 24, spring 25 and top board 26.Pull bar 21 has an axle collar 210 that is positioned at its middle part, and one end of pull bar 21 is connected with the piston rod 31 of cylinder 30, and installing plate 22 is socketed on pull bar 21.

A pair of supporting seat 23 is arranged on installing plate 22, and is relatively arranged on the both sides of pull bar 21.Specifically, the bottom of supporting seat 23 has installing hole, and the two ends of installing plate 22 also have installing hole, utilizes the installation elements such as bolt that supporting seat 23 is fixed on installing plate 22.Each supporting seat 23 comprises 231He bottom, top 232, and top 231 tilts towards pull bar 21, and it has an angle of inclination with respect to bottom 232; Top 231 comprises between 233, two arms 233 of two arms that are parallel to each other having interval 234, and each arm 233 has mounting hole 235 on its incline direction, and mounting hole 235 positions on two arms 233 of each supporting seat 23 are relative.

Spring 25 is socketed on pull bar 21, and the lower end of spring 25 is supported by the axle collar 210 of pull bar 21, upper end roof supporting 26.The two ends of top board 26 lay respectively in the interval 234 on two supporting seat 23 tops 231, and can in interval 234, slide up and down.A pair of jaw 24 is supported on respectively on the two ends of top board 26, and is positioned partially in interval 234.On each jaw 24, be installed with oval pin 241 and short cylindrical pin 242, long and short straight pin 241,242 crosses jaw 24, and their two ends stretch out from jaw 24, coordinates respectively with two mounting holes 234 on each supporting seat 23.Mounting hole 234 is stretched out at the two ends of oval pin 241, and is positioned at the below of the rectangular recess 13 of location-plate 10, and rectangular recess 13 can play the movement travel that the oval pin 241 of restriction makes progress.The alloy sword pawl 243 that Hardmetal materials is made is housed on the opposite face of two jaw 24 upper ends, and its head is worn into keen edge, is conducive to clamping and positioning pin 100.

The outside of one of them of two supporting seats 23 is provided with long adjustment rack 51, the outside of another supporting seat 23 is provided with short adjustment rack 52, long and

short adjustment rack

51,52 is U-shaped, on the two legs of long adjustment rack 51, have screwed hole, on the two legs of short adjustment rack 52, have the screwed hole of perforation, the screwed hole that screw 53 passes on short adjustment rack 52, then stretch in the screwed hole of long adjustment rack 51, thereby long and

short adjustment rack

51,52 is coupled together.Long and

short adjustment rack

51,52 the rigidity that has increased on the one hand supporting seat 23 is set; On the other hand, by the distance between fine-tuning two supporting seats 23 of the degree of tightening of adjustment screw 53, thereby finely tune two jaws 24, when open configuration, open distance, make the size of the alignment pin that power pin removal of the present utility model can choose allow there is change in less size range.

The size of the alignment pin that power pin removal of the present utility model can be chosen also can have change in larger size range, by the distance between the installing hole at change installing plate 22 two ends, can change the distance between two supporting seats 23, thereby make can the choose alignment pin of various sizes of power pin removal.

The process of pulling pin of the utility model power pin removal is described below in conjunction with Fig. 5 a～5c.

As shown in Figure 5 a, power pin removal is in original state.Under original state, the piston rod 31 of cylinder 30 is in elongation state, pull bar 21 and the installing plate 22 being mounted thereon and supporting seat 23 are withstood on higher position by piston rod 31, the motion that oval pin 241 on jaw 24 makes progress is subject to the restriction of rectangular recess 13 on location-plate 10 and downward Compress Spring 25, oval pin 241 is positioned at mounting hole 235 bottom, now, distance between two jaws 24 is maximum, in open configuration, alignment pin 100 can be put between two jaws 24 through the rectangular opening 11 of location-plate 10.

After alignment pin 100 is put between two jaws 24, power pin removal implements to clamp action.As shown in Figure 5 b, piston rod 31 retractions of cylinder 30, drive pull bar 21 and supporting seat 23 to move downward, now spring 25 is released, and by top board 26, upwards promotes jaw 24, and the long and short straight pin 241,242 on jaw 24 moves upward along mounting hole 235, jaw 24 moves upward with respect 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 implements to choose action.As shown in Figure 5 c, the piston rod 31 of cylinder 30 continues retraction, drives pull bar 21 and whole slip pin pulling out device 20 to move downward, thereby the alignment pin 100 that is clamped at slip pin pulling out device 20 is extracted.

The power pin removal assembly that the utility model discloses is not limited to the structure of the content described in above embodiment and accompanying drawing representative.On basis of the present utility model to the shape of member wherein and apparent change that position is done, substitute or revise, all within the claimed scope of the utility model.
