Abstract
The utility model relates to a fixture for the processing of a round hole in a cylinder workpiece. The fixture for the processing of the round hole in the cylinder workpiece comprises a base, a compression block and a drilling jig, wherein a semi-circular groove 11 and a semi-circular embedment groove are formed in the base; a semi-circular groove 21 is formed in the compression block; a square groove is formed in the bottom part of the drilling jig; drill holes are formed in the top end of the drilling jig; the semi-circular groove 11 in the base and the semi-circular groove 21 in the compression block are matched to form a circular hole; the square groove in the drilling jig is located right above the semi-circular groove 11 in the base; a positioning column and a supporting block are installed on one side wall of the base; the positioning column and the semi-circular embedment groove are in interference fit; an installation hole is formed in the supporting block; a positioning bolt is installed in the installation hole; and the end part of the positioning bolt stretches out of the supporting block. The fixture for the processing of the round hole in the cylinder workpiece is simple in structure and flexible to operate.
Description
Technical field
The utility model relates to technical field of tooling clamps, relates in particular to the positioner of cylinder shape workpiece circular hole processing.
Background technology
Process circular hole on coupled columns bodily form workpiece, if locate not in place, workpiece is easy to rotate in process, and cause on workpiece the machining accuracy of circular hole undesirable, and in actual production process, although can guarantee that to a certain extent the processing of circular hole on cylinder shape workpiece meets the requirements, the frock more complicated affects production efficiency.
The utility model content
The utility model provides a kind of positioning fixture for above-mentioned shortcoming of the prior art, and it is simple in structure, flexible operation.
The technical scheme that the utility model adopts is as follows:
Cylinder workpiece circular hole tool for processing comprises base, compact heap and drill jig, on base with semi-circular groove and semicircle caulking groove; On compact heap with semi-circular groove; The bottom of drill jig has square groove, and the top of drill jig is with boring; Semi-circular groove on the base composition circular port that matches with semi-circular groove on compact heap; Square groove on drill jig be in semi-circular groove on base directly over; On one sidewall of base, locating dowel and back-up block are installed, locating dowel and semicircle caulking groove interference fit with installing hole, are equipped with bolt by described installing hole on back-up block, and back-up block is stretched out in the end of bolt;
Further technical scheme is as follows:
The axis of the semi-circular groove on described bolt and base is perpendicular;
Described locating dowel and base are matched in clearance;
Described compact heap and drill jig all are fixedly connected with base by soket head cap screw.
The utility model has the advantage of: at the semi-circular groove mix proportion circular hole that arranges on base on semi-circular groove and compact heap, the cylinder workpiece is stretched out in this circular hole, again by fixing drill jig on base, boring on drill jig is aligned the cylinder workpiece, workpiece is carried out Drilling operation, by the locating dowel on base, workpiece is carried out circumferential registration simultaneously, prevent that workpiece rotating from affecting machining accuracy, and by bolt, workpiece is carried out horizontal location, make the location more stable, guarantee the machining accuracy of workpiece, simple in structure, flexible operation.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As Fig. 1 and shown in Figure 5, the utility model comprises base 1, compact heap 2 and drill jig 3, compact heap 2 and drill jig 3 all are fixedly connected with base 1 by soket head cap screw, on base 1 with semi-circular groove 11 and semicircle caulking groove 12; On compact heap 2 with semi-circular groove 21; The bottom of drill jig 3 has square groove 32, and the top of drill jig 3 is with boring 31; Semi-circular groove 11 on the base 1 composition circular port that matches with semi-circular groove 21 on compact heap 2; Square groove 32 on drill jig 3 be in semi-circular groove 11 on base 1 directly over; Locating dowel 6 and back-up block 4 are installed on one sidewall of base 1, locating dowel 6 and semicircle caulking groove 12 interference fit, on back-up block 4 with installing hole, by described installing hole, bolt 5 is housed, the axis of the semi-circular groove 11 on bolt 5 and base 1 is perpendicular, and back-up block 4 is stretched out in the end 7 of bolt 5;
Using method of the present utility model is as follows:
The first step needs an end of machining hole to insert in the circular hole of compact heap 2 and base 1 composition workpiece 8;
Second step coordinates the circumferential registration position on workpiece 8 with locating dowel 6 on base 1, workpiece 8 is carried out circumferential registration, prevents that workpiece 8 from rotating in process;
In the 3rd step, rotational positioning bolt 5 makes its end 7 coordinate with circular trough on workpiece 8, from horizontal direction, workpiece is positioned, and makes the location of workpiece 8 more stable.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
