Description
Technical field
The utility model relates to a kind of instrument of pulling pin.
Background technology
Pin mainly is to be used for fixing two relative positions between the assembly parts, perhaps realizes connection between the assembly parts etc., generally all is interference fit, after pin tightens, is difficult to.Therefore, when mode is dismantled pin usually, may damage assembly parts on the one hand, pin also may be destroyed on the other hand.Especially high assembly parts of precision prescribed are had relatively high expectations to repeating installation accuracy, and do not allow assembly parts are impacted and influence such as stress, and the common instrument of pulling pin can not meet the demands.
Summary of the invention
The purpose of this utility model is to propose a kind ofly can to protect assembly parts, reusable pin, easy to operate, the labour-saving instrument of pulling pin; it has solved the technical problem of damaging assembly parts and pin, being unfavorable for repeating to install assembly easily when the existing instrument of pulling pin is dismantled pin, is to be applicable to that cylindrical pin with internal thread and taper pin with internal thread work the specific purpose tool that pulls out.
The technical solution of the utility model patent is:
A kind of instrument of pulling pin, its special character is, it comprises spanner 1, nail nipping part 2 and support member 4, described nail nipping part 2 comprises nail nipping part head 21 and nail nipping part bar portion 22, described spanner 1 is inner hexagon spanner or outer-hexagonal spanner, described nail nipping part head 21 is the hexagon socket head portion or the outer-hexagonal head that can cooperate with spanner 1, described nail nipping part bar portion 22 is cylindrical bars, its lower end circumferential surface be provided with can with the external screw thread of the screw-internal thread fit of pin 6, described support member 4 comprises support member via hole 41 and the support member pit 42 that communicates up and down, the diameter of described support member via hole 41 is little compared with the diameter of nail part head 21, diameter compared with nail part bar portion 22 is big, and the internal diameter of described support member pit 42 is bigger than the diameter of pin 5 heads.
The above-mentioned instrument of pulling pin comprises at least one bed hedgehopping spare 3, and the shape of described bed hedgehopping spare 3 and support member 4 are complementary, and it is provided with the bed hedgehopping spare via hole 31 that connects upper and lower surface.
Above-mentioned bed hedgehopping spare 3 can be pad or nut.
Above-mentioned nail nipping part 2 can be soket head cap screw, outer-hexagonal screw, hexagon socket head cap screw or outer-hexagonal bolt.
The utlity model has following characteristics:
1, use this instrument of pulling pin, not only can protect assembly parts, and can not destroy pin, pin is reusable.
2, easy to operate, laborsaving, can be used for rising of cylindrical pin with internal thread and taper pin with internal thread and pull out.
3, this instrument manufacturing is simple, and part can be gathered materials on the spot.
Description of drawings
Fig. 1 is the utility model structural representation; Wherein: 1-spanner, 2-nail nipping part, 21-nail nipping part head, 22-nail nipping part bar portion, 3-bed hedgehopping spare, 4-support member, 41-support member via hole, 42-support member pit, 5-assembly parts, 6-pin.
The specific embodiment
A kind of instrument of pulling pin, comprise spanner, nail nipping part and support member, the nail nipping part comprises nail nipping part head and nail nipping part bar portion, spanner is inner hexagon spanner or outer-hexagonal spanner, nail nipping part head is a hexagon socket head portion that can cooperate with spanner or outer-hexagonal head, nail nipping part bar portion is a cylindrical bar, its lower end circumferential surface be provided with can with the external screw thread of the screw-internal thread fit of pin, support member comprises support member via hole and the support member pit that communicates up and down, the diameter of support member via hole is little compared with the diameter of nail part head, diameter compared with nail part bar portion is big, and the internal diameter of support member pit is bigger than the diameter of pin head.In order to adapt to the pin of different size, the utility model instrument of pulling pin also can be equipped with at least one bed hedgehopping spare, requires the center of bed hedgehopping spare that a bed hedgehopping spare via hole that connects upper and lower surface need be set, and bed hedgehopping spare generally is the shim-like part, and available pad or nut replace.This bed hedgehopping spare can be arranged on the below or the top of support member, also one even a plurality of bed hedgehopping spare can be set simultaneously in the above and below of support member; If bed hedgehopping spare is arranged on the top of support member, require the diameter of its via hole little, big compared with the diameter of nail part bar portion compared with the diameter of nail part head, if bed hedgehopping spare is arranged on the below of support member, require the diameter of its via hole bigger than the diameter of pin head, its upper surface should be able to support support member.For easy to use, bed hedgehopping spare can adopt the standard component pad or the standard component nut of serial size.The nail nipping part can adopt soket head cap screw, outer-hexagonal screw, hexagon socket head cap screw or outer-hexagonal bolt.
When using this to pull pin instrument, at first bed hedgehopping spare is placed the top of assembly parts, again support member is placed the top of bed hedgehopping spare, again another bed hedgehopping spare is placed the top of support member, play the via hole of the via hole of via hole that head part bar portion passes top bed hedgehopping spare successively, support member and pit, below bed hedgehopping spare, corresponding with the endoporus of pin then, nail nipping part head support is at bed hedgehopping spare upper surface.Can guarantee when the axial dimension of bed hedgehopping spare and support member is suitable that the nail nipping part screws in pin endoporus 1 to 3 button, and between shank and support member, leave the space that pin is extracted.When pulling pin, when spanner turned clockwise the nail nipping part, nail nipping part bar portion screwed in the pin, and relative position shortens, because nail nipping part head is spacing by bed hedgehopping spare, pin is pulled up.
