Abstract
The invention discloses a surface punching clamp which comprises two cylindrical clamp bodies and locking bolts. The two clamp bodies are oppositely fixed; planes are symmetrically milled on the external arc surfaces of the clamp bodies; shaft fixing holes are formed on the opposite end faces of the clamp bodies; a first round hole is formed in the center of the upper plane of one clamp body; a second round hole is formed in the center of the lower plane of the other clamp body; the first round hole and the second round hole are communicated with the shaft fixing holes; the clamp bodies have locating screw holes; and the locating screw holes are internally provided with the locking bolts. The surface punching clamp provided by the invention is simple and convenient for manual operation, the labor intensity of workers is greatly reduced, the position precision of holes can be guaranteed, the processing precision is high, and the surface punching clamp is suitable for batch production.
Description
Technical field
The present invention relates to a kind of anchor clamps, relate in particular to a kind of on the working shaft-like piece surface respectively near the surperficial perforating clamp in one group of relative hole of its end face.
Background technology
In field of machining, often to carry out perforation processing to the surface of some axial workpieces, these holes have concrete regulation usually, such as respectively near one group of relative hole of the end face of axial workpiece.Existing processing method commonly used all is the location of directly carrying out on axial workpiece first a little, then mark, use again special anchor clamps clamping workpiece, then carry out perforation processing, but in processing, will repeat like this clamping and the mark fixed point of workpiece, workman's complex operation, labour intensity is large, and the positional precision in hole can not guarantee that working (machining) efficiency is poor, is not suitable for production lot processing.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of simple to operation, working (machining) efficiency is high and can guarantee the surperficial perforating clamp of the positional precision in hole.
Technical solution of the present invention is a kind of surperficial perforating clamp of realizing like this, comprises two cylindric clamp bodies and clamping screw; Described two relative fixed placement of clamp body; Described clamp body periphery symmetry is milled with the plane; Have axis placing hole on the opposing end surface of described clamp body; The upper plane central authorities of a described clamp body have the first circular hole; The lower plane central authorities of described another clamp body have the second circular hole; Described the first circular hole and the second circular hole communicate with axis placing hole; Have positioning screw hole on the described clamp body; Be provided with clamping screw in the described positioning screw hole.
Preferably, have two positioning screw holes on the described clamp body.
Preferably, the axis of described two positioning screw holes is positioned at same straight line, and parallel and plane.
Preferably, described clamping screw is the outer-hexagonal clamping screw.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Surperficial perforating clamp of the present invention, when the surface of axial workpiece need to process respectively relative one group of hole near its end face, the two ends of axial workpiece are placed into respectively in the axis placing hole of two clamp bodies, then by clamping screw axial workpiece is fixed, by the first circular hole and the second circular hole axial workpiece is carried out perforation processing at last.Surperficial perforating clamp of the present invention, the workman is simple to operation, greatly reduces workman's labour intensity, and the positional precision in hole can guarantee that working (machining) efficiency is high, is applicable to batch machining.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of surperficial perforating clamp as shown in Figure 1 comprises two cylindric clamp bodies 1 and clamping screw; Described two clamp bodies, 1 relative fixed placement; Described clamp body 1 periphery symmetry is milled with plane 2; Have axis placing hole 3 on the opposing end surface of described clamp body 1; Upper plane 2 central authorities of a described clamp body 1 have the first circular hole 4; The lower plane central authorities 2 of described another clamp body 1 have the second circular hole 5; Described the first circular hole 4 and the second circular hole 5 communicate with axis placing hole 3; Have two positioning screw holes 6 on the described clamp body; The axis of described two positioning screw holes 6 is positioned at same straight line, and parallel and plane 2; Be provided with clamping screw in the described positioning screw hole; Described clamping screw is outer-hexagonal clamping screw 7.
Of the present invention a kind of surperficial perforating clamp shown in accompanying drawing 2-3, when the surface of axial workpiece 8 need to process respectively relative one group of hole near its end face, the two ends of axial workpiece 8 are placed into respectively in the axis placing hole 3 of two clamp bodies 1, then by outer-hexagonal clamping screw 7 axial workpiece 8 is fixed, carried out perforation processing by the first circular hole 4 and 5 pairs of axial workpieces of the second circular hole at last.
Surperficial perforating clamp of the present invention, the workman is simple to operation, greatly reduces workman's labour intensity, and the positional precision in hole can guarantee that working (machining) efficiency is high, is applicable to batch machining.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
