Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Embodiment one
As shown in figure 1, a kind of disassembling positioning pin device is present embodiments provided, including one end (does not show with alignment pin in figure
Go out) on screwed hole threaded connection mobile jib 1 of pulling pin, the body 2 of pulling pin being threadedly coupled with the other end of mobile jib 1 of pulling pin is described to pull out
The thread rotary orientation phase that pin mobile jib 1 coordinates with the thread rotary orientation for the cooperation of body 2 of pulling pin and mobile jib 1 of pulling pin with the screwed hole on alignment pin
Instead.
For carrying out the alignment pin that interference fits are positioned using Morse taper and positioning hole, using the present embodiment
When described disassembling positioning pin device dismantles such alignment pin, positive screw in of the body 2 that will pull pin first is pulled pin on mobile jib 1, then will
Pull pin mobile jib 1 the screwed hole that reversely screws on alignment pin of one end in can not extremely continue to screw；Body 2 of pulling pin reversely is screwed to cause
Body 2 of pulling pin gradually is moved to alignment pin, and the body 2 that makes to pull pin is pressed on workpiece close to the end face of one end of alignment pin；By
Pressed in body 2 of pulling pin on work folder, continued reversely to screw when pulling pin body 2, body 2 of pulling pin can not continue pulling pin
Moved on mobile jib 1, according to the operation principle of feed screw nut, mobile jib 1 of now pulling pin will be moved, that is, mobile jib 1 of pulling pin will be to remote
Move in direction from workpiece.Due to thread rotary orientation and pull pin mobile jib 1 and the positioning of pull pin mobile jib 1 and the cooperation of body 2 of pulling pin
Thread rotary orientation that screwed hole on pin coordinates on the contrary, and mobile jib 1 of pulling pin can not continue to revolve with the screwed hole on alignment pin
Twist, therefore reversely screw when pulling pin body 2, pull pin and do not relatively rotated between mobile jib 1 and alignment pin, that is, mobile jib 1 of pulling pin
When being moved to the direction away from workpiece, alignment pin by as mobile jib 1 of pulling pin moves together and eventually disengages from the positioning hole on workpiece,
Complete the dismounting of such alignment pin.
Disassembling positioning pin apparatus structure described in the present embodiment is simple, when dismantling corresponding alignment pin using the device, behaviour
Make simply, labor intensity is small.
Specifically, in the present embodiment, the mobile jib 1 of pulling pin includes the first threaded rod 11, the second threaded rod being sequentially distributed
12 and bolt head 13, first threaded rod 11 be adapted with the screwed hole on alignment pin, second threaded rod 12 is with pulling pin
The screw thread of body 2 coordinates.
The thread rotary orientation of the thread rotary orientation of first threaded rod 11 and the second threaded rod 12 with anti-reverse screw on the contrary, pulled out
When selling body 2, pull pin and relatively rotated between mobile jib 1 and alignment pin.The diameter of first threaded rod 11 is less than the second spiral shell
The diameter of rasp bar 12, positive screw in of body 2 of being easy to pull pin are pulled pin on mobile jib 1.
In the present embodiment, the body 2 of pulling pin includes the first tool cover 21 coordinated with the screw thread of the second threaded rod 12, and
The screw thread of the second tool cover 22 coordinated with the screw thread of the first tool cover 21, first tool cover 21 and the cooperation of mobile jib 1 of pulling pin revolves
To opposite with the thread rotary orientation that the second tool cover 22 coordinates with the first tool cover 21.It is probably heavy to install the positioning hole of alignment pin
Hole, then after installing, the end face distance workpiece of the one end of the first threaded rod 11 away from the second threaded rod 12 is close to the second work
The end face distance of tool set 22 is different, by changing the corresponding tool cover 22 of second tool cover 22 second away from the first tool cover
The end face of 21 one end can be pressed on the end face of workpiece.
Due to first tool cover 21 and the thread rotary orientation and the first tool cover 21 and the second instrument of the cooperation of mobile jib 1 of pulling pin
The thread rotary orientation that set 22 coordinates on the contrary, and require that the first tool cover 21 and the second tool cover 22 are anti-in that can not continue when in use
To the position screwed so that when reversely screwing the first tool cover 21, phase will not occur for the first tool cover 21 and the second tool cover 22
To rotating.Drive the second tool cover 22 to rotate by reversely screwing the first tool cover 21 when in use, while drive mobile jib 1 of pulling pin
It is mobile, and then realize the dismounting of alignment pin.Second tool cover 22 can also be pressed on work by the present embodiment close to the end face of workpiece
On part, by reversely screwing bolt head 13 so that bolt head 13 is relative to the first tool cover 21 to away from the second tool cover 22
Direction is moved, due to so that the first tool cover 21 and the second tool cover 22 be in the position that can not continue reversely to screw, pull pin master
Bar 1 will drive alignment pin movement, and then realize the dismounting of alignment pin.
In the present embodiment, second tool cover 22 connects the end face and workpiece of one end of alignment pin close to mobile jib 1 of pulling pin
It is upper installation alignment pin end face be adapted, and second tool cover 22 press on workpiece install alignment pin end face when can
Rotated relative to workpiece.Relatively rotate due to existing when dismantling alignment pin, between the second tool cover 22 and workpiece, therefore, make
For optimal technical scheme, second tool cover 22 is plane close to the end face of one end that mobile jib 1 of pulling pin connects alignment pin.
In the present embodiment, the end face of the described one end of second tool cover 22 away from bolt head 13 and the first tool cover 21 are remote
The distance between end face of the one end of bolt head 13 is more than the length of alignment pin.The external diameter of the alignment pin is more than first screw thread
The external diameter of bar 11, and less than the internal diameter of the second tool cover 22.In actual use, alignment pin can be made to pass through the second tool cover 22
And first screw out between threaded rod 11.
Obviously, above-described embodiment of the present utility model is used for the purpose of clearly illustrating the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.All made within spirit of the present utility model and principle all any modification, equivalent and improvement etc., should be included in
Within the protection domain of the utility model claims.
