Embodiment
Specific embodiment in below in conjunction with the accompanying drawings is described further the utility model.
Refering to Fig. 2-4, a kind of pin pulling tool of the utility model, including the spacing collar 1 of hollow structure and it is plugged in this
The pull rod 2 of hollow structure in spacing collar 1, it is dismountable in pull rod 2 to be equipped with the pin pulling head 3 being connected with pin, in pull rod 2
It is interior to be equipped with the limited block 4 locking onto pin pulling head 3 in pull rod 2, prevent pin pulling head 3 from departing from pull rod 2；Wherein, pull rod 2 is by left-handed
Screw thread is connected with spacing collar 1, and pin pulling head 3 is connected by right-handed thread with pin, matches somebody with somebody between pin pulling head 3 and pull rod 2 for gap
Close, specifically, the spliced eye 5 being adapted with the maximum gauge of pin pulling head 3 is equipped with pull rod 2, wherein, limited block 4 is located at should
Pin pulling head 3, is positioned at the lower part of pull rod 2 by the bottom of spliced eye 5, it is preferred that the axis of spacing collar 1, pull rod 2 and pin pulling head 3
Heart line coincides, it is ensured that the orientation consistency of pin dismounting.The spacing collar 1 and pull rod 2 of the utility model pass through left hand thread
Engagement, and by being engaged by rotation screw thread between pin pulling head 3 and pin, risen by rotating clockwise pull rod 2, so as to fulfill extraction
Pin, the utility model is simple in structure, easy to make, only 1 two components of pull rod 2 and spacing collar, the processing of two components
Required precision is not high and need not carry out any heat treatment, greatly optimizes the structure of pin extracting tool, reduces production
Cost, also, dedicated pin pulling head is not required in the pin pulling tool of the utility model, and can be directly using live soket head cap screw just
Pin pulling head can be served as, use is very simple and convenient.
In the present embodiment, pin pulling head 3 is the platform of T-shaped soket head cap screw, the top surface of limited block 4 and the T-shaped soket head cap screw
Terrace is engaged, and is formed the mistake nail 6 spacing, limited block 4 is adapted equipped with the stud with the T-shaped soket head cap screw, is easy to
Soket head cap screw is connected through limited block 4 with pin, and 2 t shape of pull rod is arranged, including first to be connected with spacing collar 1
Connecting portion 7 and above the first connecting portion 7 and the first coupled force section 8,7 and first force section of first connecting portion
8 are integrally formed, and left hand thread is equipped with the periphery of first connecting portion 7, and the left hand thread is axial arranged along first connecting portion 7,
Correspondingly, 1 t shape of spacing collar is arranged, including the second connecting portion 9 that is connected with pull rod 2 and under the second connecting portion 9
The second square and coupled force section 10,9 and second force section 10 of second connecting portion is integrally formed, in second connecting portion 9
Periphery is equipped with left hand thread, and the screw thread of first connecting portion 7 and second connecting portion 9 is adapted, also, is set in the second force section 10
There is the accommodating chamber 11 that the minimum diameter with pull rod 2 is adapted, so that pull rod 2 is plugged in spacing collar 1, in the second force section 10
Lower part, which is equipped with, to be used to observe the observation panel 12 that pin pulls up state, which is U-shaped window, and person easy to operation understands in real time
The situation of pin dismounting.
The pin pulling tool of the present embodiment, in practical work process, is first put into 2 inner cavity of pull rod by pin pulling head 3, then will draw
Bar 2 is screwed in spacing collar 1, pin pulling head 3 is exposed 10~15mm, is completed the assembling of pin pulling tool；Then by the pin pulling tool
The top of pin to be torn open is placed in, pin pulling head 3 is rotated clockwise using allen wrench, it is screwed into pin to be torn open；Then
Steady brace 2, and rotary stopper sleeve 1 counterclockwise, make its bottom surface be contacted with the surface of machinery equipment and are connected, finally keep spacing
Sleeve 1 is motionless, and rotates clockwise pull rod 2, pin to be torn open is departed from the axial displacement of pull rod 2 from machinery equipment, when
When pin pulling head 3 and pull rod 2 rotate clockwise at the same time, the distance of 2 every turn lifting pin of pull rod is equal to the pitch and pin pulling head of pull rod 2
The sum of 3 pitch, when pin pulling head 3 is not active, the distance of 2 every turn lifting pin of pull rod is equal to the pitch of pin pulling head 3, dismounting effect
Rate is more increased.
Above-described is only the preferred embodiment of the utility model, it should be pointed out that is come for those skilled in the art
Say, on the premise of the utility model structure is not departed from, several modifications and improvements can also be made, these are all without this reality of influence
