Description
Technical field
The present invention relates to a kind of specific purpose tool of disassembling positioning pin, especially a kind of straight pin that can extract plurality of specifications or
The specific purpose tool of taper bolt belongs to maintenance tool technical field.
Background technique
In order to improve the machining accuracy of mechanical equipment running accuracy and pressure processing mold, need through straight pin or circular cone
Pin is accurately positioned the opposite position come between strict guarantee mechanical equipment components, between the mould heart and bottom plate of pressure processing mold
Set precision.In maintenance of equipment or when the more mold changing heart, it is necessary first to which the straight pin or taper bolt for extracting positioning just can be carried out subsequent
Process.Existing stock class pin removal, which is only equipped with, extracts the cylindrical pin with internal thread of several specifications or the bolt special of taper bolt,
Sometimes also need to be equipped with different pin removals, corresponding straight pin or taper bolt could be extracted, use is very inconvenient, versatility compared with
Difference, and bolt special is easily lost.When pulling pin, stock class pin removal must be perpendicular to the mounting plane of straight pin or taper bolt,
Required operating space has to be larger than the length of pin removal.When operating space is less than the length of pin removal, existing pin removal
Just it is not available.
Summary of the invention
The object of the present invention is to provide a kind of structures to be simple and convenient to operate, can be in the operating space for being less than pin removal length
The interior pin removal for extracting straight pin or taper bolt and method of pulling pin.
The present invention is achieved by the following technical programs:
A kind of pin removal is pulled out including dead man, percussion hammer and the first plug component being separately fixed on dead man both ends and second
Head assembly, the percussion hammer cover on dead man, and the first plug component includes support and regular polygon plug, the second plug component
Including support and Y-shaped plug, dead man both ends are fixedly connected with corresponding support one end respectively, polygon plug or multi-fork shape
Plug passes through bolt and nut group respectively and the corresponding support other end is hinged.
The purpose of the present invention can also be further realized by following technical measures.
Pin removal above-mentioned, wherein a part of side center in regular polygon plug vertically extends different rule outward respectively
The stud of lattice, the stud are matched with the specification of cylindrical pin with internal thread or taper pin with internal thread.In another portion of regular polygon plug
The center on point side is respectively equipped with the internal thread hole of different size, the internal thread hole and external screw thread straight pin or external screw thread taper bolt
Specification matching.
Pin removal above-mentioned, wherein each bifurcated of Y-shaped plug end face center be respectively equipped with specification it is different in
Threaded hole, the internal thread hole are matched with the specification of external screw thread straight pin or external screw thread taper bolt.
Pin removal above-mentioned, wherein center stud line or internal thread hole center line are directed to the hinged center of support.
A kind of method of pulling pin of pin removal includes the steps that two kinds of following A, B different operating conditions are corresponding:
A, the straight pin or taper bolt outer space pulled out can accommodate pin removal length
A1) that polygon plug or Y-shaped plug is hinged by bolt and nut group and the support other end, respectively constitute the
One plug component or the second plug component；
A2 it) according to the type and specification for being pulled out straight pin or taper bolt, selects corresponding first plug component or second pulls out
Head assembly rotates regular polygon plug or Y-shaped plug, selects stud corresponding with the straight pin or taper bolt that are pulled out and divides
Then the external screw thread of the stud of regular polygon plug or Y-shaped plug is screwed into being pulled out by the corresponding external screw thread of fork-shaped plug
In cylindrical pin with external thread or the threaded hole of taper pin with internal thread outer end；The internal thread hole of regular polygon plug and the external screw thread circle pulled out
The thread head of pin or the thread head of external screw thread taper bolt are fixedly connected or the internal thread hole of Y-shaped plug and the outer spiral shell that is pulled out
The thread head of line straight pin or the thread head of external screw thread taper bolt are fixedly connected；
A3) will put on the dead man both ends of percussion hammer respectively with one end of one end of support and another support is fixed connects
It connects；
A4 percussion hammer quickly) is pulled repeatedly, constantly hits the bottom of the support other end away from the straight pin or taper bolt pulled out
Face, until straight pin or taper bolt are pulled out；
B, the straight pin or taper bolt outer space pulled out cannot accommodate pin removal length
B1) repeat A1) and A2) the step of, the group of the first plug component or the second plug component of completing pin removal is filled with
And regular polygon plug or Y-shaped plug with pulled out cylindrical pin with internal thread, taper bolt or external screw thread straight pin, taper bolt is consolidated
Fixed connection；
B2 support first) is rotated 90 °, is then fixedly connected with dead man one end with support one end, keeps dead man axial along quilt
Pull out straight pin or taper bolt mounting surface direction；Then upper percussion hammer is covered on the dead man other end, in percussion hammer side and the interior spiral shell pulled out
Cushion block is placed between the mounting surface of line straight pin or external screw thread straight pin, holds the dead man other end around the hinged center pendulum of support
It is dynamic, so that percussion hammer side is hit cushion block repeatedly, until pulling out straight pin or taper bolt.
The present invention installs the first plug component and the second plug component at dead man both ends respectively, and each component includes cutting with scissors each other
The plug and support connect circumferentially sets up multiple and different specifications separately in plug and axis is directed toward the stud and internal screw thread at the hinged center of support
Hole, so that corresponding plug can be around the hinged center rotating of support, to match the straight pin or taper bolt of different size.Structure letter
It is single, it is easy to use, it does not need to be equipped with a variety of pin removals, versatility is good.Dedicated stud is fixed on plug, can be to avoid loss.
One pin removal can extract the straight pin or taper bolt of common or dedicated specification, improve work efficiency.Of the invention pulls pin
Support can be rotated 90 ° by method, keep dead man axial along being pulled out straight pin or taper bolt mounting surface direction, so that it may by dead man as
Crowbar pulls out the straight pin or taper bolt pulled out, and the narrow of pin removal length can not cannot accommodated by solving existing pin removal
The problem used in small space.
The advantages and features of the present invention will be illustrated and explained by the non-limitative illustration of preferred embodiment below,
