Abstract

The invention relates to an application method of an arched plate drilling positioning device. The application method comprises the following steps: (1) a lower mold is fixed on a console; (2) a workpiece is put on an arched surface of the lower mold; (3) an upper mold and the lower mold are positioned, and are fixed by screws, so that the workpiece is clamped between the upper mold and the lower mold; and (4) the workpiece is drilled through a drill on the upper mold. The application method of the arched plate drilling positioning device has the advantages of simple structure, flexibility and convenience for use, simple clamping and high machining precision.

Description

The using method of arc drilling-hole positioning device

Technical field

The present invention relates to technical field of tooling clamps, particularly relate to positioner and the using method thereof of arc being carried out to Drilling operation.

Background technology

Workpiece 1 as described in Figure 1, it is arc tabular, now needs to portal 11 to processing on it, because two face is arcwall face, use common positioning tool also can reach accurate location, but the general more complicated of frock, clamping is loaded down with trivial details, and machining accuracy is also difficult to ensure.

Summary of the invention

The present invention is directed to above-mentioned shortcoming of the prior art, provide a kind of arc drilling-hole positioning device and using method thereof, its structure is simple, and flexible and convenient to use, machining accuracy is high.

The technical solution adopted in the present invention is as follows:

The using method of arc drilling-hole positioning device, comprises the steps:

The first step, is first fixed to counterdie on operating desk;

Second step, is placed in workpiece in the cambered surface of counterdie;

3rd step, has good positioning patrix and counterdie, and makes to be screwed, and makes Workpiece clamping between patrix and counterdie;

4th step, is processed by the boring of patrix and portals on workpiece.

The invention has the advantages that: be divided into upper die and lower die, and the bottom surface radian of patrix is identical with the radian of workpiece surface, both can be made to fit tightly, patrix arranges the boring identical with machining hole position degree needed for workpiece, counterdie is arranged alignment pin and patrix is accurately located, also locating slot is set simultaneously, the top of the two side of locating slot arranges charging conduit and facilitates the waste material on workpiece to discharge, structure is simple, and flexible and convenient to use, machining accuracy and efficiency easily ensure.

Fig. 2 is the structural representation of patrix of the present invention.

Fig. 3 is the structural representation of counterdie of the present invention.

Fig. 4 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 Figures 1 to 4, the present invention includes patrix 2, counterdie 3, the tow sides of patrix 2 are cambered surface, uniform four borings 22 on patrix 2, the position degree of four borings 22 is identical with the position degree in the hole of four on workpiece, ensure that hole 11 position degree that workpiece 1 processes meets the requirements, with screw hole 23 and locating hole 21 on patrix 2, with U-shaped locating slot 31 on counterdie 3, can counterdie 3 be fixed on operating desk, the both sides end face 32 of locating slot 31 is arc, the radian of end face 32 is identical with the radian of workpiece lower camber side, can ensure that end face 32 and workpiece 1 lower surface fit tightly, workpiece 1 uniform force is balanced, with alignment pin 33 and charging conduit 34 on end face 32, alignment pin 33 coordinates with the locating hole 21 of patrix 2, the waste material that charging conduit 34 can add man-hour is discharged in time, and cutter can be avoided to contact with counterdie 3, the bottom surface of locating slot 31 is threaded hole, screw 4 is used to be connected in the screwed hole on U-shaped locating slot 31 through the screw hole 23 of patrix 2, by patrix 2 and counterdie 3 fastening,

Using method of the present invention is as follows:

The first step, is first fixed to counterdie 3 on operating desk;

Second step, is placed in workpiece 1 in the cambered surface 32 of counterdie 3;

3rd step, has good positioning patrix 2 and counterdie 3, and uses screw 4 to fix, and makes workpiece 1 be clamped between patrix 2 and counterdie 3;

4th step, is processed by the boring 22 of patrix 2 and portals 11 on 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.

Claims
