Abstract
The utility model discloses a quick tightening spanner for a threaded connection piece. The quick tightening spanner comprises a handle, a bow-shaped rocking arm and a tightening head, wherein the upper end of the bow-shaped rocking arm is inserted into and connected with a hollow part of the handle; a magnetic hexagonal ball body at the lower end of the bow-shaped rocking arm is mounted in a hexagonal groove in the upper part of the tightening head; a screw hole is formed in the lower part of the tightening head; the handle is of a hollow structure; symmetric bumps are formed on the two sides of the inner wall at the lower end of the handle respectively; an annular groove is formed in one end, connected with the handle, of the bow-shaped rocking arm. The quick tightening spanner is simple in structure and convenient to operate, and can be used for effectively solving the problem of difficulty for tightening caused by poor thread accuracy of a small-diameter dual-head stud and the machine part screw hole or poor matching accuracy between the small-diameter dual-head stud and the machine part screw hole, shortening the assembly time to the hilt and improving the work efficiency.
Description
Technical field
The utility model belongs to a kind of impact wrench, is specifically related to a kind of threaded connector Quick fastening spanner.
Background technology
At present, in machinery assembling industry, being threaded is one of important method of attachment, and screw processing quality has considerable influence to the assembling complexity.Studs is one of standard component of commonly using, because it does not have impetus, uses existing instrument it can't be tightened.Especially quality problems appear in screw thread or the parts screw when studs, perhaps occur the relatively poor phenomenon of quality of fit between the two, all can cause its obstruction to be tightened because frictional force is excessive and put in place, how to solve a difficult problem that this phenomenon becomes the assembler.
Two kinds of solutions are generally arranged when running into the problems referred to above in production: the first adopts two nuts identical with the studs specification in the double-screw bolt upper end, that it is fastening, use again corresponding tool such as ratchet spanner etc., the rotation upper nut with studs screw put in place after, again with corresponding tool fixedly lower nuts after oppositely unscrewing upper nut, it is backed off, process so loaded down with trivial details time-consuming, inefficiency; It is two after to be electric wrenches of adopting bidirectional rotation directly squeeze into studs among screw by forward, reverse again electric wrench is backed off from double-screw bolt, although this processing method speed because moment can't accurately be controlled, causes double-screw bolt to be taken out of in the process of the counter-rotating of being everlasting.
Summary of the invention
The utility model proposes in order to overcome the shortcoming that exists in prior art, its objective is provides a kind of effective specific purpose tool for machinery assembling industry studs assembly process, specifically a kind of simple in structure, easy to operate threaded connector Quick fastening spanner.
The technical solution of the utility model is: a kind of threaded connector Quick fastening spanner comprises handle, arc rocking arm and screws head.The hollow connection of handle is inserted in the upper end of described arc rocking arm, and magnetic six side's sphere installations of arc rocking arm lower end are formed with screw screwing a bottom in screwing six square grooves on a top.
Described handle is hollow structure, and its inwall both sides, lower end respectively are formed with a symmetrical projection.
The end that described arc rocking arm is connected with handle is formed with cannelure, and the projection on the position of cannelure, size and handle inwall is complementary.
Work in coordination at described six side's spheroids and six square grooves.
The utility model is simple in structure, easy to operate, effectively solved because the accuracy of thread of small diameter studs and parts screw is slightly poor, or quality of fit between the two is slightly poor and the problem that is difficult to be screwed into that causes has shortened installation time to greatest extent, has improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model threaded connector Quick fastening spanner.
Wherein:
1 handle
2 arc rocking arms
3 magnetic six square toes
4 screw head
5 magnetic six side's spheroids
6 six square grooves
7 screws
8 projections.
The specific embodiment
Below, with reference to drawings and Examples, a kind of threaded connector Quick fastening of the utility model spanner is elaborated:
As shown in Figure 1, a kind of threaded connector Quick fastening spanner comprises handle 1, arc rocking arm 2 and screws 4.Wherein, handle 1 is hollow structure, and its inwall both sides, lower end respectively are formed with a symmetrical projection 8, and the end that arc rocking arm 2 is connected with handle 1 is formed with cannelure, and the projection 8 on the position of cannelure, size and handle 1 inwall is complementary.Projection 8 coordinates with cannelure and has the axial limiting effect, makes operator's convenient operation.
The lower end of arc rocking arm 2 is formed with magnetic six square toes 3 and magnetic six side's spheroids 5, is formed with six square grooves 6 screwing 4 top, and 4 bottom is formed with screw 7, six side's spheroids 5 and six square grooves 6 are worked in coordination screwing.Change the size of screw 7 according to the model standard of studs, design the head that screws of different size, use in order to change.Fast changeable screw head design, both made the screw-in of different size stud become simple and easy, be convenient to withdraw from and be difficult for double-screw bolt is taken out of after studs is screwed.Screw and only contain 3 ~ 4 button screw threads in head, when screwing backed off after random, screw 4 with the frictional force of the studs frictional force less than screw and studs,, the situation of when having avoided instrument to withdraw from, double-screw bolt having been taken out of.
The hollow connection of handle 1 is inserted in the upper end of arc rocking arm 2, and the projection 8 on handle 1 and the cannelure on arc rocking arm 2 are worked in coordination.Magnetic six side's spheroids 5 of arc rocking arm 2 lower ends are arranged in six square grooves 6 that screw 4 top.Six side's spheroids 5 adopt has ferromagnetic material manufacturing, and the convenient arc rocking arm 2 of the design of ferromagnetism six side's spheroids is recognized fast and accurately into screwing in 4, and can avoid screwing 4 problem of having lost after EO.
Because magnetic six side's spheroids 5 and six square grooves 6 are six sides, make arc rocking arm 2 can be in 0 ~ 25 ° of scope tilt operation arbitrarily, improved the convenience of operation.
Using method of the present utility model:
At first, an end of studs is screwed in a screw 7 of 4.Then hold Quick fastening pinch bar 1, will screw 4 and align the studs upper end, directly shake clockwise continuously arc rocking arm 2, studs is screwed in rapidly put in place.At last, shake counterclockwise arc rocking arm 2 and can withdraw from fast studs, complete operation.
The utility model is simple in structure, easy to operate, effectively solve because the accuracy of thread of small diameter studs and parts screw is slightly poor, or the slightly poor and problem that is difficult to be screwed into that causes of quality of fit between the two, shorten to greatest extent whole installation time, improved operating efficiency.
