Abstract

The utility model relates to the field of manufacturing of a plastic mould and particularly relates to a semicircular machining clamp for machining a high-precision semicircular work piece in batches. The semicircular machining clamp comprises a clamp main body and is characterized in that the clamp main body is a column body formed by a top plane and a bottom circular-arc-shaped surface; the cross section of the clamp main body is in a semicircular structure; a lug boss is arranged at the center of each of two ends of the top plane of the clamp main body; and the two ends of the clamp main body are respectively provided with two screw through holes. Compared with the prior art, the error of a machining size is controlled in the tolerance of 0.01 mm; in a machining process, a production line form can be adopted; all machining processes can be carried out at the same time; and particularly, in a large-batch production process, the efficiency can be improved, the cost is controlled and the best effect is achieved.

Description

A kind of semicircle clamp for machining of high accuracy semicircular workpieces
Technical field
The utility model relates to plastic mould and makes field, specifically a kind of semicircle clamp for machining for batch machining high accuracy semicircular workpieces.
Background technology
In actual applications, to use in a large number the part of semicircle on some equipment or the mechanical device, and higher to dimensional requirement, common processing mode is that each product is processed separately, efficient is low, and is second-rate, also has to use anchor clamps to carry out batch machining, but efficient is carried to be come up always, and quality is poorly control also.
Summary of the invention
The purpose of this utility model provides a kind of semicircle clamp for machining of high accuracy semicircular workpieces for overcoming the deficiencies in the prior art, and these anchor clamps are relatively low to operative employee's specification requirement, improved simultaneously operating efficiency and machining accuracy.
In order to achieve the above object, the utility model has designed a kind of semicircle clamp for machining of high accuracy semicircular workpieces, comprise jig main body, it is characterized in that: the cylinder of described jig main body for being formed by a plane, top and an end arc surface, its cross section is semi-circular structure, a boss is respectively established in center at the two ends, plane, top of described jig main body, respectively establishes two screw via holes at the two ends of described jig main body.
Further, also be provided with center hole on the described boss.
Further, to be higher than the height on the plane, top of jig main body be d=0.20mm in the center of described center hole.
Further, two of described each end of jig main body equal Central Symmetry settings of screw via hole.
The utility model is compared with prior art, and the error of processing dimension is controlled in the tolerance of 0.01mm, adds can adopt the streamline form man-hour, all processing can be carried out simultaneously, especially when producing in enormous quantities, more can raise the efficiency, control cost, reach best effect.

Referring to Fig. 1---Fig. 6,1 is jig main body; 2 is boss; 3 is the screw via hole; 11 are the plane, top; 12 is end arc surface; 21 is center hole.
The specific embodiment
Now the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, the utility model comprises jig main body 1, jig main body 1 is the cylinder that is comprised of a plane 11, top and an end arc surface 12, its cross section is semi-circular structure, a boss 2 is respectively established in center at 11 two ends, plane, top of jig main body 1, respectively establish two screw via holes 3 at the two ends of jig main body 1, two screw via holes, the 3 equal Central Symmetry settings of jig main body 1 each end.Also be provided with center hole 21 on the boss 2, the height that the center of center hole 21 is higher than the plane, top 11 of jig main body 1 is d=0.20mm.
The utility model carries out semicircular workpieces and adds man-hour, semicircular workpieces and jig main body 1 are combined together, fix by screw via hole 3 with screw, then hang on the lathe, after top the withstanding of center hole 21 usefulness on the two ends boss 2 of jig main body 1, gear is transferred to correct position begins processing, again through after a series of milling machine processing, just can access high-precision semicircular workpieces, the error of processing dimension is controlled in the tolerance of 0.01mm.
The utility model adds can adopt the streamline form man-hour, and all processing can be carried out simultaneously, especially when producing in enormous quantities, more can raise the efficiency, and controls cost, and reaches best effect.
