Abstract
The utility model discloses a kind of straight pin flange and rush tool, comprise drift, also comprise punching lid, described punching lid is column type, in be formed centrally shoulder hole, described shoulder hole is made up of path unthreaded hole and large footpath screw; Described drift is made up of column type hand grip portion, transition round platform, column type connecting portion, transition cylinder and conus portion successively, and connecting portion outer surface forms external screw thread, and is threaded with the large footpath screw of shoulder hole.The utility model structure is simple, and be easy to manual operations, low cost of manufacture, long service life, effectively avoids the formation of penetrating crack, and after ensureing flange, excircle dimension meets quality requirement.
Description
Technical field
The utility model belongs to a kind of flange and rushes tool, is specifically related to a kind of straight pin flange and rushes tool.
Background technology
Straight pin is mainly used in location, also can be used for connecting or do axle and uses.Straight pin does the axle used time, due to axially without location, easily moves axially.Therefore, prior art is improved straight pin.As shown in Figure 1, straight pin 11 is circular platform type structure to straight pin after improvement, and in one end perforate of straight pin 11, and splits nose end and carry out flange source, forms flange 1.After improvement, truncated cone-shaped straight pin rank and flange 13 structure effectively prevent moving axially of straight pin.In order to manufacture the truncated cone-shaped straight pin that this type of has turnup structure, conventional rush tool flange after flange 13 excircle dimension cannot ensure, and easily form penetrating crack again, the quality requirement after flange cannot be ensured.
Utility model content
The utility model proposes to overcome the shortcoming existed in prior art, and its object is to provides a kind of straight pin flange to rush tool.
The technical solution of the utility model is:
A kind of straight pin flange rushes tool, comprises drift, also comprises punching lid, and described punching lid is column type, in be formed centrally shoulder hole, described shoulder hole is made up of path unthreaded hole and large footpath screw; Described drift is made up of column type hand grip portion, transition round platform, column type connecting portion, transition cylinder and conus portion successively, and connecting portion outer surface forms external screw thread, and is threaded with the large footpath screw of shoulder hole.
The basal diameter of described conus portion is identical with transition cylinder, and matches with shoulder hole path unthreaded hole, and the height of conus portion is greater than the length of shoulder hole path unthreaded hole.
On described transition round platform, end face diameter is identical with connecting portion diameter, and bottom surface diameter is identical with hand grip portion diameter.
The beneficial effects of the utility model are:
The utility model structure is simple, and be easy to manual operations, low cost of manufacture, long service life, effectively avoids the formation of penetrating crack, and after ensureing flange, excircle dimension meets quality requirement.

Detailed description of the invention
Rush tool below in conjunction with Figure of description and embodiment to a kind of straight pin flange of the utility model to be described in detail:
As shown in Fig. 2 ~ 5, a kind of straight pin flange rushes tool, and comprise drift 1 and rush lid 2, described punching lid 2 is column type, in be formed centrally shoulder hole 3, described shoulder hole 3 is made up of path unthreaded hole 4 and large footpath screw 5; Described drift 1 is made up of column type hand grip portion 6, transition round platform 7, column type connecting portion 8, transition cylinder 9 and conus portion 10 successively, and connecting portion 8 outer surface forms external screw thread, and is threaded with the large footpath screw 5 of shoulder hole 3.
The basal diameter of described conus portion 10 is identical with transition cylinder 9, and matches with shoulder hole 3 path unthreaded hole 4, and the height of conus portion 10 is greater than the length of shoulder hole 3 path unthreaded hole 4.
On described transition round platform 7, end face diameter is identical with connecting portion 8 diameter, and bottom surface diameter is identical with hand grip portion 6 diameter.
The utility model uses to manually, during use, conus portion 10 pinnacle of drift 1 is aimed at the central through hole of straight pin 11, impact with the hand grip portion end of the instruments such as hammer to drift 1, impulsive force makes straight pin carry out flange along the conical surface of the conus portion 10 of drift 1, and enter in the gap between conus portion 10 and shoulder hole 3 path unthreaded hole 4 inwall, ensure that its flange diameter is in acceptability limit.Rush after tool moves a certain distance, rush lid 2 and contact with part 12, the impact of drift 2 will be born by part 12, prevent the continuation increase of cylinder pin hole flange 13 diameter and the appearance of crackle.
