Abstract
The invention discloses a puller for a positioning pin. The puller comprises a first screw used for being connected with the positioning pin provided with internal threads and providing pulling force for the positioning pin, a pulling head provided with a first inner stepped hole, a pulling rod provided with a limiting boss in the middle and an inner threaded hole in the tail, and a pulling base provided with a second inner stepped hole, wherein a nut of the first screw is arranged in the inner stepped hole of the pulling head, the pulling head is fixedly connected with the end of the pulling rod through threads, the tail of the pulling rod penetrates through the second inner stepped hole to enable the limiting boss to be attached to the upper end face of a pulling body, and the tail of the pulling rod is fixedly installed in the second inner stepped hole of the pulling body through a second screw and a clamping base. The puller has the advantages of being uniform in pulling force, capable of preventing a pin hole from being damaged easily, reasonable in design, simple in structure, convenient to operate, small in size, light, convenient to dismantle, convenient to carry, low in production cost, and easy to popularize and use.
Description
Technical field
The present invention relates to the servicing unit of a kind of Mold Making and maintenance, be specifically related to a kind of for playing the drawbench with internal thread alignment pin on withdrawing pattern tool.
Background technology
In the time that mould is manufactured, a lot of alignment pins need to be installed to fix two relative positions between part, alignment pin normally sinks in the dowel hole on mould, because mould need to often be extracted alignment pin in the time assembling, so that dismounting part is proofreaied and correct.Mould also needs to extract alignment pin to the part of damage is pulled down and keeped in repair in the time of maintenance, common method of extracting alignment pin is to knock bar by one to insert in the pin-and-hole of mould from the lower end of alignment pin, then impacting alignment pin with iron hammer is taken out, in the time that dowel hole is blind hole, the method is just no longer applicable.In addition because the inhomogeneous meeting of percussion power causes pin-and-hole impaired, thereby reduce the precision of mould.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of alignment pin drawbench is provided, its pulling capacity is even, and pin-and-hole is not easily damaged, reasonable in design, simple in structure, easy to operate, volume is small and exquisite, lightweight, easy accessibility, is convenient to carrying, and production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of alignment pin drawbench, it is characterized in that: comprise for being connected with tapped alignment pin and providing the screw one of pulling capacity to it, with the drawing head of ladder endoporus one, middle part is provided with positive stop lug boss and afterbody is provided with the drawing bar of threaded interior hole and the drawing seat with ladder endoporus two, the nut of described screw one is arranged in the ladder endoporus of drawing head, described drawing head is fixedly connected with the end of described drawing bar by screw thread, the afterbody of described drawing bar is through ladder endoporus two and make limit convex and drawing body upper surface is close to, described drawing bar afterbody is fixedly mounted in the ladder endoporus two of drawing body by screw two and deck.
Above-mentioned alignment pin drawbench, is characterized in that: the nut end face of described screw one arranges flat recess or cross recess.
Above-mentioned alignment pin drawbench, is characterized in that: the external sidewall of described drawing is provided with rubber sleeve.
The present invention compared with prior art has the following advantages:
(1) this alignment pin is with drawbench in the time of drawing alignment pin, and pulling capacity is even, and pin-and-hole is not easily damaged, thereby has ensured the precision of mould.
(2) this alignment pin is very reasonable, simple in structure with drawbench design, and operating personnel only need outside drawing alignment pin can be extracted, and operate very easy.
(3) this alignment pin is small and exquisite, lightweight with drawbench volume, and easy accessibility is convenient to carrying, transport.
(4) this alignment pin is all convenient to produce, buy with all parts of drawbench very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

Detailed description of the invention
A kind of alignment pin drawbench as shown in Figure 1, comprise for being connected with tapped alignment pin 1 and providing the screw 1 of pulling capacity to it, with the drawing head 3 of ladder endoporus one 3-1, middle part is provided with positive stop lug boss 4-1 and afterbody is provided with the drawing bar 4 of threaded interior hole 4-2 and the drawing seat 5 with ladder endoporus two 5-1, the nut of described screw 1 is arranged in the ladder endoporus 3-1 of drawing head 3, described drawing head 3 is fixedly connected with the end of described drawing bar 4 by screw thread, the afterbody of described drawing bar 4 is through ladder endoporus two 5-1 and make positive stop lug boss 4-1 and drawing body 5 upper surfaces are close to, described drawing bar 4 afterbodys are fixedly mounted in ladder endoporus two 5-1 of drawing body 5 by screw 26 and deck 7.
The nut end face of described screw 1 arranges flat recess or cross recess, and flat recess or cross recess can handled easily personnel be screwed into screw 1 in the internal thread hole for the treatment of drawing alignment pin 1.
Described drawing body 5 lateral walls are provided with rubber sleeve 8, and rubber sleeve 8 can play anti-skidding effect in the time that operating personnel outwards exert oneself.
Alignment pin of the present invention by the course of work of drawbench is: first the screw with drawing head 31 is screwed in the internal thread hole for the treatment of drawing alignment pin 1, then drawing head 3 is fixed on to the end of drawing bar 4 by screw thread.Operating personnel hold outwards firmly drawing of drawing body 5, can will treat that drawing alignment pin 1 extracts smoothly.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
