Abstract
The invention relates to machining devices, in particular to a semicircular drill hole positioning device. The semicircular drill hole positioning device comprises upper cover protruding edges, upper cover bolt holes, an upper cover, a workpiece, a lower cover, lower cover protruding edges, lower cover bolt holes, circular through holes and semicircular through holes. Semicircular holes in central symmetry are formed in the two sides of the workpiece, six circular holes arranged irregularly are formed in the workpiece, the upper cover protruding edges are manufactured on the two sides of the upper cover respectively, and the six circular through holes and the two semicircular through holes are drilled in the upper cover. The semicircular drill hole positioning device has the advantages that it is achieved that the positioning precision between the holes is achieved, machining of spiral holes can be ensured, operation is convenient, the machining quality is good, efficiency is high, the labor intensity of workers is greatly lowered, the structure is simple, and manufacturing and installing are convenient.
Description
Technical field
The present invention relates to machinery processing apparatus, especially a kind of half-round drill hole positioning device.
Background technology
In field of machining, perforation processing is being carried out to the surface of some flat panel workpieces.Sometimes man-hour is being added, need in flat panel workpieces, process irregular alignment radially circular hole or semicircle orifice, existing processing method is all generally first locate to process first hole, then with first hole for datum mark, carry out fixed point on the surface of the workpiece to make marks, then one by one carry out perforation processing, although like this can work pieces process out, but such processing method needs ceaselessly repeated clamping workpiece, and the angle that will calculate between hole, complex operation, especially semicircle orifice, its location is more difficult, this will improve the labour intensity of workman, make working (machining) efficiency low, the quality of product can not ensure, inapplicable batch production.
Summary of the invention
The object of the invention is to overcome defect of the prior art, adopt a kind of half-round drill hole positioning device, realize the positional precision processing between circular hole and circular hole, easy to operate, crudy is good, and efficiency is high, greatly reduces the labour intensity of workman.
For achieving the above object, technical scheme of the present invention adopts a kind of half-round drill hole positioning device, comprise upper cover convex edge, upper cover bolt hole, upper cover, workpiece, lower cover, lower cover convex edge, bolt of lower cover hole, circular hole through hole, semicircle orifice through hole, there is centrosymmetric semicircle orifice on described workpiece both sides, there are six circular holes of irregular alignment the inside of described workpiece, the both sides of described upper cover are manufactured with upper cover convex edge respectively, described upper cover is drilled with six circular hole through holes and two symmetrical semicircle orifice through holes, described upper cover convex edge is drilled with two upper cover bolts hole, the both sides of described lower cover are manufactured with lower cover convex edge respectively, described lower cover is drilled with six circular hole through holes and two symmetrical semicircle orifice through holes, described lower cover convex edge is drilled with two bolt of lower cover holes.
Described workpiece clamp is between upper cover and lower cover, and described upper cover and lower cover are connected by bolt presses.
Beneficial effect of the present invention is:
(1) process velocity is fast, reduces the labour intensity of workman.
(2) precision can ensure, crudy is good.
(3) easy to operate, be applicable to batch machining.
