Abstract
The utility model provides a shaft tube machining fixture. The shaft tube machining fixture structurally comprises two relatively parallel sleeve elements, wherein the two sleeve elements are connected and fixed by round steel; the two sleeve elements are in a shape provided with a circular outside and a square inside, that is, the outer sides of the sleeve elements are circular, and the inner sides thereof are provided with square shaft tube placement holes, and a central frame is arranged at the outside of one of the sleeve elements in a surrounding manner; the central frame comprises an annular ring sleeved and fixed with the sleeve elements by fixing bolts, and a base arranged at the bottom of the annular ring; adjusting screws capable of stretching in the shaft tube placement holes are arranged on the outer walls of the two sleeve elements. Compared with the prior art, the shaft tube machining fixture is high in shaft tube machining efficiency, good in the concentricity of the machined shaft tube, high in practicability, wide in application range, and easy to popularize.
Description
Technical field
The utility model relates to Machining Technology field, specifically a kind of simple in structure, central siphon processing tool.
Background technology
Central siphon is the critical piece of vehicle bridge, and it requires concentricity higher, existing production process more complicated, and be difficult to ensure the concentricity of the rear workpiece of processing, in order further to improve the quality of products, a kind of central siphon processing tool is provided now, solve the concentricity problem of central siphon two stomidiums.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides that one is skillfully constructed, central siphon processing tool.
The technical solution of the utility model realizes in the following manner, a kind of central siphon processing tool, its structure comprises the external member of two opposing parallel, between two external members, be connected and fixed by round steel, described two external members are all round outside but spuare inside shape, be that rounded outside external member, inner side offers square central siphon putting hole, wherein the outside of an external member is surrounded with centre frame, this centre frame comprise by set bolt be fixed by socket this external member annular ring, be arranged on the base of annular ring bottom, on the outer wall of above-mentioned two external members, be provided with the adjustment screw that can stretch into central siphon putting hole.Two external members in this technical scheme connect by round steel, by fastened by screw, make whole mechanism become as a whole.After connection, frock entirety processing excircles, ensure that the concentricity of two covers is less than 0.05mm, practical.
As preferably, described round steel is provided with three or four and is evenly arranged between two external members.
Further, described set bolt is curved with the end that external member outer wall contacts.
The beneficial effect that the utility model compared with prior art produced is:
That a kind of central siphon processing tool of the present utility model has is simple in structure, easy to use, be skillfully constructed, the feature such as reasonable in design, the concentricity of two stomidiums can ensure below 0.1mm, has improved the precision of processing, and this frock adopts symmetric design, behind the complete one end of Vehicle Processing, the other end that can turn around to process, need not reorientate clamping, and working (machining) efficiency is high, remarkable benefit, practical, applied widely, be easy to promote.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of central siphon processing tool of the present utility model is described in detail below.
As shown in Figure 1, a kind of central siphon processing tool, its structure comprises the external member 1 of two opposing parallel, between two external members 1, be connected and fixed by round steel 2, described two external members 1 are all round outside but spuare inside shape, be that external member 1 outside is rounded, inner side offers square central siphon putting hole 3, wherein the outside of an external member 1 is surrounded with centre frame 4, this centre frame 4 comprise by set bolt 4.2 be fixed by socket this external member 1 annular ring 4.1, be arranged on the base 4.3 of annular ring 4.1 bottoms, on the outer wall of above-mentioned two external members 1, be provided with the adjustment screw 5 that can stretch into central siphon putting hole 3.
Described round steel 2 is provided with three or four and is evenly arranged between two external members 1.
Described set bolt 4.2 is curved with the end that external member 1 outer wall contacts.
In the time that reality is used, first square shaft pipe 7 is put into two external member 1 the insides of frock.Regulate position and hold out against by adjustment screw 5, workpiece and frock are tightened together, the one end of then clamping central siphon 7 at the external member 1 place chuck 6 that is not socketed centre frame, the other end is lived by 1 of centre frame place external member.Regulate the concentricity of workpiece and lathe by chuck 6, regulate the endoporus that can process central siphon 7 after centrad.After processing two ends, unclamp external member 1 adjustment screw 5 above, can take out central siphon 7.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although this detailed description of the invention part has been done to explain to the utility model; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
