Description

High-precision drilling beveled aperture positioning fixture
Technical field
The present invention relates to technical field of tooling clamps, particularly relate to the positioning fixture for carrying out Drilling operation to workpiece.
Background technology
Workpiece 1 as shown in Figure 1, it has an erose bottom 11, the sidewall of bottom 11 has certain gradient, and existing needs carry out Drilling operation and portal 12, with a cylinder 13 on bottom 11 on sidewall, plain clamp is used to acquire a certain degree of difficulty to its location, especially to ensure machining accuracy, special frock must be used just to meet the demands, and frock must be easy to use, clamping efficiency is high, can ensure its machining accuracy again simultaneously.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, provide a kind of high-precision drilling beveled aperture positioning fixture, its structure is simple, and flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
High-precision drilling beveled aperture positioning fixture, comprises base, and with rectangle positioning table on base, the first side wall of positioning table and the second sidewall are respectively with screw rod and dovetail groove, and the second sidewall is also with tilting groove, and groove is built with back-up block; Dovetail groove built with L shape briquetting, with housing screw on briquetting.
The invention has the advantages that: according to the structure of workpiece, positioning table on base arranges oblique groove, by back-up block, workpiece is played to the effect of skewed horizontal load, workpiece needs the position of boring to be the level of state, and uses screw rod and briquetting to position compression to workpiece and back-up block respectively simultaneously, reaches pinpoint for workpiece object, structure is simple, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of workpiece.
Fig. 2 is explosive view of the present invention.
Fig. 3 is using state figure of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, the present invention includes base 8, with rectangle positioning table 2 on base 8, the first side wall of positioning table 2 and the second sidewall are respectively with screw rod 3 and dovetail groove 4, screw rod 3 is for positioning the cylinder 13 on workpiece 1, on screw rod 3, mounting nuts 10 is pressed on the end face of cylinder 13, second sidewall is also with tilting groove 7, groove 7 is angled with horizontal plane, the size of angle is consistent with the gradient of 11 sidewalls bottom workpiece 1, guarantee during location that workpiece 1 needs the sidewall of processing to be the level of state, groove 7 is built with back-up block 9, back-up block 9 11 sidewalls with gradient bottom workpiece 1 support, dovetail groove 4 is built with L shape briquetting 5, and with housing screw 6 on briquetting 5, briquetting 5 can move up and down along dovetail groove 4, and housing screw 6 compresses from the sidewall of back-up block 9 it, ensures stability when back-up block 9 to support bottom workpiece 1 11,
Using method of the present invention is as follows:
The first step, is fixed on base 8 on operating desk;
Second step, is inserted on screw rod 3 by the cylinder 13 of workpiece 1;
3rd step, puts into back-up block 9 in the tilting groove 7 of positioning table 2, and regulates the height of briquetting 5 to use housing screw 6 to compress back-up block 9;
4th step, makes 11 sidewalls with gradient bottom workpiece 1 be placed on back-up block 9;
5th step, tightening nut 10 is pressed on the end face of the cylinder 13 on workpiece 1;
6th step, portals 12 in the bottom 11 sidewall processing of workpiece 1.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
