Abstract
Te utility model discloses a pin pulling tool which comprises a handle (1), cylindrical pins (2), an impact bar (3), an impact sleeve (4), a connecting rod (5), an internal tapered thread insert (6), an external tapered clamp (7) and other parts, wherein the rotatable handle (1) is mounted at one end of the impact bar (3) through the cylindrical pins (2), the shock sleeve (4) is mounted in the middle position in a jacketing manner, and the other end of the impact bar (3) is connected with one end of the connecting rod (5) through the cylindrical pins (2); the other end of the connecting rod (5) is connected with the internal tapered thread insert (6); and the external tapered clamp (7) is mounted inside the internal tapered thread insert (6) in a jacketing manner. When the internal tapered thread insert (6) is rotated, a pin is clamped by the external tapered clamp (7), and the impact sleeve (4) reciprocates to impact the step surface of the impact bar (3), so that the pin can be pulled out quickly. The pin pulling tool has the advantages of simple structure, reliability of clamping, convenience and quickness in operation, low manufacturing cost and convenience in use.
Description
Technical field
The utility model relates to a kind of instrument of pulling pin, and relates in particular to a kind of instrument that can be quickly and easily round pin nail or cotter pilotage nail puller be gone out.
Background technology
In the engine manufacturing, a lot of positions need to do the location assembling with round pin nail or cotter pilotage nail on the engine, usually an end interference fit of pin edge is tightly on a part, when needing repairing, traditional way is to adopt chisel that pin is dug out, be about to the sharp end of chisel and withstand on the pin cylindrical with hammer and beat slowly cutter outward of chisel, take out quite difficulty of pin, very time-consuming, effort gas.For solving the problem of above existence, need design and produce a kind of instrument that quickly and easily round pin nail or cotter pilotage nail puller is gone out.
Summary of the invention
The purpose of this utility model is to provide that a kind of to overcome prior art circumscribed, impact bar one end connects handle, the other end connects coupling bar, the nail of waiting to pull pin packs into coupling bar, the impact bar intermediate active is set with impingement sleeve, expose partly, also move back and forth impingement sleeve vertically by chuck reliable grip pin, utilize impulse inertia that pin is extracted easily and quickly.
Technical solution of the present utility model, comprise parts such as handle, straight pin, impact bar, impingement sleeve, coupling bar, inner conical swivel nut, male-tapered chuck, circle hole shape chuck, O shape circle, it is characterized in that impact bar one end connects with handle by first straight pin, be set with impingement sleeve in the impact bar centre position, the impact bar other end connects with coupling bar one end by second straight pin, the annular groove of coupling bar cylindrical is set with O shape circle, the other end of coupling bar and inner conical swivel nut adopt thread connection, and inner conical swivel nut internal sleeve is equipped with the male-tapered chuck.
The inner conical swivel nut is a hexagonal shape hollow structure, and an end center is processed with screw and matches with coupling bar small end external screw thread, and screw thread hole bottom is processed with circular escape, and inner conical swivel nut other end center is processed with the female cone hole, this female cone borehole jack nail that advances to pull pin.
Male-tapered chuck one end is processed with outer cone and matches with the female cone hole of inner conical swivel nut, and is processed with cross recess vertically, and the center is processed with flat blind hole, and the other end is cylindric, and excircle dimension is less than the path of inner conical swivel nut center screw.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect: impact bar one end is equipped with rotating handle by straight pin, the centre position is set with impingement sleeve, the other end connects with coupling bar one end by straight pin, the other end of coupling bar connects with the inner conical swivel nut, and inner conical swivel nut internal sleeve is equipped with the male-tapered chuck.By twisting the inner conical swivel nut, make the male-tapered chuck clamp pin, moving back and forth impingement sleeve impact bar step surface can extract pin fast outward.Simple in structure, reliable clamping, easy to operate, quick, cheap for manufacturing cost, easy to use.
