Abstract
The utility model provides a jig for boring and clamping a high precision optical centering normal hole, which is provided with a reloading clamping drill holder and an auxiliary pressing plate of an optical centering piece sleeve. The optical centering piece sleeve is made of transparent materials, and the end surface thereof contacting with the curved surface of a workpiece is provided with centering steel balls with same size and height protruded out of the end surface, and the centering steel balls are in uniform trisection distribution. The optical centering normal drilling jig has simple and convenient operation, accurate positioning of the centering steel balls, easy guarantee of the vertical precision of the holes, high machining efficiency and convenient reloading of the clamping drill holder and the optical centering piece sleeve, so that the problem of difficult alignment of the verticality of the normal hole when a bench worker uses a centimeter to center in marking a line is solved.
Description
Technical field
The utility model relates to a kind of drill jig that is mainly used in boring, brill high accuracy normal direction hole.
Background technology
The normal direction hole is a very common class workpiece, common processing method generally is by pincers worker line, with the dial gauge method for centering to processing.The weak point of the processing method of above-mentioned prior art is an inefficiency, and the normal direction hole perpendicularity is difficult for guaranteeing.
Summary of the invention
Of the present utility model is at above-mentioned the deficiencies in the prior art part, provides a kind of easy and simple to handle, vertical precision height, the normal direction hole drill mould that can increase work efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of optical centering normal direction hole drill mould, auxiliary pressure strip with change the outfit a clamping drill bushing and an optical centering spare sleeve, it is characterized in that, optical centering spare sleeve by the transparent material making, its with end face that curve surface of workpiece contacts on, be shaped on the uniform centering ball of trisection of outstanding face size height unanimity.
The utility model is that than the beneficial effect of prior art normal direction hole drill mode structure size can change with the variation of processing work.Easy and simple to handle, the centering ball accurate positioning, the hole vertical precision easily guarantees, working (machining) efficiency height, clamping drill bushing and optical centering spare sleeve change the outfit conveniently.Solved the pincers worker line, with the centering of dial gauge centering, the problem that the normal direction hole perpendicularity is difficult for sighting.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model optical centering normal direction hole drill mould.
Fig. 2 is that the A of Fig. 1 is to view
Fig. 3 is the working state schematic representation of Fig. 1.
The specific embodiment
In Fig. 1～Fig. 3, be shaped on the threaded connection hole of can change the outfit a clamping drill bushing and an optical centering spare sleeve on the auxiliary pressure strip 1.The size that system assists pressure strip to press practical work piece is determined, so that clamping and clamping.The actual size of drill bushing external diameter is consistent with described optical centering spare sleeve.Normal direction hole drill mode structure size can be with the change in size of processing work 4.
The optical centering spare sleeve of being made by transparent material 2 has an optical centering centre bore 3 with the machining hole central axes.It with end face that workpiece 4 curved surfaces contact on, be shaped on fixedly centering ball 5, by the uniform positioning and fixing groove of trisection.Centering ball 5 protrudes in the end face of optical centering spare sleeve 2 rotationally, and size height unanimity.Before to the boring of workpiece 4 normal direction hole systems, center with optical centering spare earlier, the centering ball 5 that trisection is uniform is put into the positioning and fixing groove, makes its bulge size height unanimity, rotate flexibly, and complex-shaped workpiece 4 curved surfaces of even contact.Then, be fixed auxiliary pressure strip 1 downwards, get closing in ready.Take off optical centering spare again, change drill bushing and carry out boring (brill) drilling.
Claims (2)
1. optical centering normal direction hole drill mould, auxiliary pressure strip with change the outfit a clamping drill bushing and an optical centering spare sleeve, it is characterized in that, optical centering spare sleeve by the transparent material making, its with end face that curve surface of workpiece contacts on, be shaped on the uniform centering ball of trisection of outstanding face size height unanimity.
2. optical centering normal direction hole drill mould as claimed in claim 1 is characterized in that the actual size of drill bushing external diameter is consistent with described optical centering spare sleeve.
