Abstract

A double-screw-hole type scriber for locating with a right triangular coordinate comprises a streak plate and a height vernier caliper put on the working surface of the streak plate. The scriber also comprises a chuck for clamping the workpiece to scribe the lines, wherein the chuck is shaped like a regular triangular prism; a pair of screw holes is arranged on the front end face of the chuck and is vertical to the front end face; and bolts are arranged in the screw holes. During scribing, being clamped only once, the workpiece can scribe all the correct processing lines in three coordinate directions forming angles of 60 degrees mutually and is fast, convenient and precise in locating. The scriber dispenses with aligning during scribing, the scribing precision completely depends on the manufacturing precision of the chuck and is irrelevant with the aligning process, and the scriber has the advantages of high scribing precision and good repeatability of the scribed lines. The scriber is simple in manufacturing process and low in manufacturing cost.

Description

The scriber of two screw-hole type triangular coordinates location

Technical field

The present invention relates to the scriber of a kind of pair of screw-hole type triangular coordinates location.

Technical background

At centering on the end face of disc-like part or on the end face at the plate class part of random profile or when drawing positive triangle intersection with regular profile, all want in advance one or at least two datum levels of completion of processing part, come the disc-like of regular profile or the plate class workpiece of random profile are positioned with this datum level, determine processing boundary accurately by centering with by means of the method for material again.Operating process is more original, and is also more loaded down with trivial details.

The orientation tool of the end face line of existing disc-like part to regular profile is that v block, magnetic position line by iron and the first-class device of calibration substantially, lean on the positioning and marking device of iron for v block, magnetic, though it is simple in structure, the equipment price is not high yet, operate also easyly, but it locatees time line ratio of precision to round-disk shape workpiece lower, and centering positions line at least at twice, that is rule is repeated poor for this reason; And just cumbersome for the line of the centering of random profile part, be with first completion of processing first datum level substantially and reach the corresponding techniques requirement, again with processing second basis on the basis of this first datum level.And in scratching process, being to buttress disk type work with hand substantially, is purpose to reach positioning and locking.And the dividing head positioning and marking device, though workpiece location line precision height, repeatability rule better by institute, and its technology assembling is complicated, and equipment price height is more than several thousand yuan substantially, and operates complexity.

Summary of the invention

The time need multiple clamping for what overcome prior art in line, the shortcoming of complicated operation the invention provides clamping of a kind of need and can mark all right processing boundary, line precision height, simple to operate, the scriber of two screw-hole type triangular coordinates location that cost is low.

The scriber of two screw-hole type triangular coordinates location, comprise streak plate and the vernier height gauge that is placed on the described streak plate working face, it is characterized in that: described scriber comprises that also one clamps the clamp device of workpiece to be crossed, described clamp device is regular triangular prism, the front end face of described clamp device has a pair of screw, described screw is vertical with described front end face, is provided with bolt in the described screw.

Further, be provided with compress gasket between described screw and the bolt.

Further, the angle between the adjacent two sides of described clamp device be 60 ° ± 1 '.

Further, the described front end face and first side, second side or the 3rd lateral vertical side degree are less than or equal to 0.01mm, and the described rear end face and first side, second side or the 3rd lateral vertical side degree are less than or equal to 0.01mm.

Further, the perpendicularity of described screw and described front end face is less than or equal to 0.04mm.

Further, the surperficial roughness of each of described clamp device is 0.8 μ m.

Technical conceive of the present invention is: formed three groups of fixed coordinates axles that are in 60 ° of angles in clamp device, in scratching process, only need duplicate institute's clamping to these the three groups fixed coordinates axles that are in 60 ° of angles on the workpiece of this clamp device, just can centering or mark a series of triangle intersection and parallel lines.The front end face of clamp device of the present invention has screw, bolt is slid onto and position that workpiece size to be rule is complementary, screws bolt with clamping work pieces, can rule to workpiece.

During line, clamping workpiece between the compress gasket of front end face and two bolts, is screwed bolt,, lock workpiece by changing the distance of clamping at the compress gasket of front end face and bolt.

First side of this clamp device is placed on the streak plate, just can marks first processing boundary with vernier height gauge, can be by adjusting the height dimension of vernier height gauge, mark with first processing boundary parallel a series of processing boundary; Drawing when becoming second processing boundary of 60 ° of angles with first processing boundary, as long as this clamp device rotation 120 is spent, second side is placed on the streak plate, just can mark second processing boundary with vernier height gauge again, can be by adjusting the height dimension of vernier height gauge, mark with second processing boundary parallel a series of processing boundary; Drawing when becoming the 3rd processing boundary of 60 ° of angles with second processing boundary, as long as this clamp device rotation 120 is spent, the 3rd side is placed on the streak plate, just can mark the 3rd processing boundary with vernier height gauge, can be by adjusting the height dimension of vernier height gauge, mark with the 3rd processing boundary parallel a series of processing boundary.

When the present invention rule, workpiece is as long as a clamping just can mark all right processing boundary at three coordinate directions that are in 60 °, and was quick and convenient, and accurate positioning; Need not centering during line, the line precision depends on the accuracy of manufacture of clamp device fully, and is irrelevant with the process of centering, has line precision height, the advantage of the good reproducibility of being rule; And manufacturing process of the present invention is simple, and is cheap for manufacturing cost.
