Abstract

The utility model disclose a split bolt which mainly consists of a double-head bolt and a smooth-cut-face nut, wherein threaded heads are arranged at two sides of the double-head bolt; the smooth-cut-face nut is screwed up at the threaded head at the end of the double-head bolt so as to form a T-shaped groove bolt. In installation, the smooth-cut-face nut is firstly placed in a T-shaped groove, then a clamping and fixing tool is arranged at a proper position, and then the double-head bolt and the smooth-cut-face nut is screwed up, and finally a common nut is used for screwing the other head of the double-head bolt for fixing the clamping and fixing tool. The split bolt is simple in structure, low in cost and flexible to use and material consumption is low.

Description

The split bolt
Technical field
The utility model relates to the fixing T type slot bolt of milling machine clamping and positioning frock, particularly a kind of split bolt.
Background technique
General milling machine and the machining center of using of processing of available engine cylinder block end face and hole processing, all-in-one-piece T type bolt is used in fixing of clamping and positioning frock at present.This bolt is with thick bar turning processing, not only needs a large amount of turning in man-hour, and unusual waste material.
Summary of the invention
The purpose of the utility model is to provide a kind of existing integral type T type bolt that overcomes, and makes the processing more complicated, removes most material with bar turning, needs a large amount of turning in man-hour, takes time and effort and the manufacture cost height.Tighten light bevel nut at the thread head of stud bolt, the other end has plain nut, and cooperation is fixed with the nut bidirectional modulation, and is simple in structure, and materials are economized, and cost reduces, the split bolt of convenient, flexible use.
The technical solution of the utility model is such: a kind of split bolt; Comprise stud bolt light bevel nut; It is characterized in that there is thread head at the stud bolt two ends, light bevel nut both sides are that light scabbles face, and light bevel nut is screwed into the thread head of stud bolt one end.
There is bevel the centre of stud bolt.
The utility model has the advantages that compared with prior art; The structure of split is divided into two separate parts that connect each other again with original integrated type bolt, has not only satisfied the requirement of fixing tool, has also made things convenient for processing and fabricating simultaneously; Save material, reduced cost of production.Be easy to processing.Can be with obtaining stud bolt than big slightly some bar turning of bolt; Nut also can be processed with bigger slightly plate.Save material, reduce cost.
Description of drawings
It is such that the structure of the utility model constitutes:
Fig. 1 is the stud bolt plan view of the utility model.
Fig. 2 is the light bevel nut plan view of the utility model.
Fig. 3 is an existing technology integral type T type bolt plan view.
Fig. 4 is an existing technology integral type T type bolt left view.
Among Fig. 1~Fig. 4, bevel (1), light circle (2), thread head (3), light bevel nut (4), stud bolt (5).
Embodiment
The utility model most preferred embodiment be such: with reference to accompanying drawing, by stud bolt (5) termination light bevel nut (4) is installed and is constituted split type bolt.Stud bolt (5) has thread head (3) for two ends, and there is bevel (1) centre, and bevel (1) dual-side is a light circle (2).Light bevel nut (4) is the nut that bi-side have the light bevel; The outside thread engagement of light bevel nut (4) internal thread and thread head (3); The processing of stud bolt (5) is to use the bar turning bigger slightly than stud bolt (5) to obtain stud bolt (5), and it is to be used for preventing the flat position that spanner rotates when tighting a bolt that bevel (1) is arranged in the middle of the stud bolt (5).The also available bigger slightly Sheet Metal Processing of the processing of nut, light bevel nut (4) is made the nut that there is the light bevel both sides, and two smooth bevels are used for clamping tool and snap in the nut of screwing in the thread head (3) of stud bolt (5).The split type stud bolt (5) and the light bevel nut (4) that are changed into present design by existing integral type T type slot bolt are synthetic.During installation, earlier light bevel nut (4) is placed in the T type groove of clamping and positioning frock, afterwards the thread head (3) of stud bolt (5) one ends is tightened with light bevel nut (4).Re-using plain nut tightens the other end of stud bolt (5) and fixes the clamping and positioning frock.

Claims (2)

1. a split bolt comprises stud bolt, light bevel nut, it is characterized in that there is thread head (3) at stud bolt (5) two ends, and light bevel nut (4) dual-side is that light scabbles face, and light bevel nut (4) is screwed into the thread head (3) of stud bolt (5) one ends.
2. according to the described split bolt of claim 1, it is characterized in that there is bevel (1) centre of stud bolt (5).
