Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
It is described in further detail below in conjunction with technical solution of the attached drawing to the utility model embodiment, it is clear that described reality
Applying example is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention,
It is practical new to belong to this for those skilled in the art's every other embodiment obtained without creative efforts
The range of type protection.
As shown in Figure 1, present embodiment provides a kind of pin pulling out device, which is used to extract the pin in metal tooling,
The device includes magnetic bases 1, crossbeam 2 and component 3 of pulling pin.Wherein, crossbeam 2 is supported on magnetic bases 1；Component 3 of pulling pin packet
Superposed rotating part 31 is included, the threaded rod 32 positioned at intermediate position and the plug 33 positioned at lower part, threaded rod 32 are threaded through
On crossbeam 2, plug 33 is equipped with can be with the screw thread wait nail connection of pulling pin.
In the present embodiment, crossbeam 2 is set to the top of two magnetic bases 1, and is detachably connected with magnetic bases 1.Tool
Body, the first threaded hole is equipped at the top of two magnetic bases 1, the position corresponding with the first threaded hole of crossbeam 2 is equipped with the second spiral shell
Pit wears the first threaded hole and the second threaded hole using screw element, so that magnetic bases 1 and crossbeam 2 are fixed, screw element can
Select bolt.It should be pointed out that magnetic bases 1 are used for and metal tooling magnetic absorption.
Perforative internal thread hole is equipped among crossbeam 2, threaded rod 32 is threaded through in internal thread hole, by rotating in the forward direction or instead
To rotating threaded rod 32, so that threaded rod 32 rises or falls relative to crossbeam 2.Further, in order to avoid being used for a long time
Component 3 of pulling pin in the process causes to wear to crossbeam 2, and hollow boss 21, the axis and internal screw thread of boss 21 are equipped at the top of crossbeam 2
The axis in hole is overlapped, and the diameter of 21 hollow space of boss is not less than the diameter of internal thread hole；Preferably, the hollow space of boss 21
Rounded, the diameter of hollow space and the diameter of internal thread hole are equal.It should be pointed out that there is also other works for boss 21
With rotating part 31 is equal to the thickness of boss 21 with 2 minimum range of crossbeam, when rotating part 31 is located at the position nearest apart from crossbeam 2
When, due to the presence of boss 21, facilitates technical staff to place spanner, provide space to turn rotating part 31.
Further, the rotating part 31 on 3 top of component of pulling pin is hex nut, turns rotating part by spanner when use
31, and then threaded rod 32 is driven to rotate.Flange 34 is arranged in 31 lower end of rotating part, and the diameter of flange 34 is greater than the straight of rotating part 31
