Problems solved by technology

[0002] like figure 1 The workpiece 1 described above is in the shape of a curved plate, and now it is necessary to process a hole 11 on it. Since its two surfaces are both curved surfaces, accurate positioning can also be achieved by using ordinary positioning tools, but the tooling is generally more complicated. , the clamping is cumbersome, and the machining accuracy is difficult to guarantee

Embodiment Construction

[0011] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0012] Such as Figure 1 to Figure 4 Shown, the present invention comprises patrix 2, counterdie 3, and the positive and negative sides of patrix 2 are arc surfaces, and four boreholes 22 are uniformly distributed on patrix 2, and the position degree of four boreholes 22 is exactly the same as that on the workpiece. The position of the four holes is the same to ensure that the position of the hole 11 processed on the workpiece 1 meets the requirements. The upper die 2 has a screw hole 23 and a positioning hole 21; the lower die 3 has a U-shaped positioning groove 31, which can The lower mold 3 is fixed on the operating table, the top surfaces 32 on both sides of the positioning groove 31 are arc-shaped, and the arc of the top surface 32 is the same as that of the lower arc surface of the workpiece, which can ensure that the top surface 32 ...

Abstract

The invention relates to an arc-shaped plate drilling positioning device which comprises an upper die and a lower die. The front and back surfaces of the upper die are cambered surfaces. Four drilling holes are evenly formed in the upper die. The positions of the four drilling holes are identical with those of the four holes in a workpiece. A screw hole and positioning holes are formed in the upper die. A U-shaped positioning groove is formed in the lower die. The top surfaces on two sides of the positioning groove are arc-shaped, the radian of the top surfaces is identical with that of the lower cambered surface of the workpiece, and each top surface is provided with a positioning pin and blanking grooves. Threaded holes are formed at the bottom of the positioning groove. The arc-shaped plate drilling positioning device is simple in structure, flexible and convenient to use, simple in clamping, and high in machining precision.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a positioning device for drilling arc-shaped plates. Background technique [0002] Such as figure 1 The workpiece 1 described above is in the shape of an arc-shaped plate, and now it is necessary to process a hole 11 on it. Since its two surfaces are both arc-shaped, accurate positioning can also be achieved by using ordinary positioning tools, but the tools are generally more complicated. , the clamping is cumbersome, and the machining accuracy is difficult to guarantee. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides an arc-shaped plate drilling positioning device, which has a simple structure, flexible and convenient use, and high processing precision. [0004] The technical scheme adopted in the present invention is as follows: [0005] The arc-shaped plate drilling positioning device include...
