Description
Technical field
The utility model is related to Automatic manual transmission fields, and in particular to a kind of device for taking out pin.
Background technology
During Automatic manual transmission, we often connect two parts using pin, and shop bolt is typically to sink to machine
In pin mounting hole on tool part.In assembling process or after the completion of assembling, we often need to extract pin to part
Assembling revision or repair are carried out, and the method for existing positioning pin of choosing is usually to be pulled out using instruments such as pliers, hand hammer, perching knives
Positioning pin is taken, but this mode is easily damaged pin hole and pin, it is serious to directly result in scrapping for former part；Another kind is just
It is using the threaded drawing bar in a head, is screwed in the threaded hole of shop bolt, firmly rotate and pull drawing bar,
Shop bolt can be extracted, but in order to ensure the assembly precision between part, shop bolt and the pin hole on part it
Between cooperation it is more compared with tight and pin quantity therefore inconvenient for operation and time-consuming and laborious using this method.
CN201711932U discloses a kind of taking-out tool of spiral positioning pin, for by taking out positioning pin, including main body
It portion and is arranged on the rotating part of main part one end and is arranged on the screw thread of the main part other end and is arranged among main part
, the casing with main part activity cooperation；The main part is provided with external screw thread, and described sleeve pipe is provided with and external screw thread cooperation
Internal thread.
Above-mentioned documents are directed to externally threaded pin, and the male thread portion of the pin does not sink to pin
It is in mounting hole but exposed outside part, thus above-mentioned documents and unresolved pin all sink in pin hole choose it is tired
The problem of difficult.
The content of the invention
In view of the drawbacks described above of the prior art, the utility model provides a kind of device for taking out pin, can solve
Prior art write off nail is time-consuming and laborious, and be easy to cause pin and the impaired problem of pin hole.
To achieve the above object, the utility model provides a kind of device for taking out pin, including leading screw and sleeve, sleeve
It is sheathed on outside leading screw, length sleeve is less than the length of leading screw, and leading screw upper end is provided with first handle, and the lower end of leading screw is provided with
Threaded rod, the screw hole of threaded rod and pin afterbody coordinate, and sleeve is provided outside second handle, and sleeve inner is divided into two sections, epimere
For the threaded portion being connected with leading screw, hypomere is holding part, and the diameter of holding part is more than the major diameter of threaded portion and the diameter of pin.
Preferably, first handle is circle, second handle is made of two symmetrically arranged handles.
Preferably, the screw thread outside leading screw is rectangular thread.
For the utility model by the cooperation in leading screw, threaded rod and first handle, it is first-hand that worker only needs a hand to rotate
Handle, it is possible to quickly and easily the present apparatus with pin be consolidated and be connected；Then in matching somebody with somebody using sleeve, leading screw and second handle
It closes, will manually be applied to the torque of second handle, pin is passed to using the screw thread between sleeve and screw, and be converted to vertical
Pin using drawing force is quickly extracted from pin hole, is chosen using the present apparatus and sunk to completely in pin hole by upward drawing force
Pin, it is convenient and efficient, it is time saving and energy saving, and can guarantee that pin and pin hole are not damaged.

Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail：
As shown in Figure 1 to Figure 2：A kind of device for taking out pin, including leading screw 1 and sleeve 2, sleeve 2 is sheathed on outside leading screw 1
Portion, 2 length of sleeve are less than the length of leading screw 1, and the lower end of leading screw 1 is provided with threaded rod 4, the screw hole of threaded rod 4 and 5 afterbody of pin
Cooperation, sleeve 2 are provided outside second handle 6, and 1 upper end of leading screw is provided with first handle 3, in order to quickly revolve threaded rod 4
In the screw hole for entering 5 afterbody of pin, two sections are divided into inside sleeve 2, epimere is the threaded portion 7 being connected with leading screw 1, and hypomere is holding part
8, and the diameter of holding part 8 is more than the major diameter of threaded portion 7 and the diameter of pin 5, has accommodating space in order to the pin of extraction.
First handle 3 is circle, in order to the singlehanded manipulation of worker and the power of application vertical direction, so as to more quickly will
The present apparatus is connected with bayonet fittings；Second handle 6 is made of two symmetrically arranged handles, in order to which worker's both hands apply simultaneously
The rotary force of horizontal direction.Screw thread outside leading screw 1 is rectangular thread, is conducive to the torque of second handle passing to pin,
So as to quickly extract pin, the efficiency for extracting pin is improved.
In use, using when first sleeve 2 and leading screw 1 are screwed, then using first handle fast and accurately by threaded rod
It screws in the screw hole of 5 afterbody of pin hole, after its stable connection, is rotated further by second handle until the bottom of sleeve 2 and flat panel workpieces 9
Surface contact, then continue to reinforcing rotation second handle, until pin 5 is pulled out completely；It not only can be fast using this method
The pin in pin hole is all sunk in the extraction of speed, and the pin extracted will not be damaged, and pin hole will not be destroyed.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
