Description

Arc surface drilling double hole positioning tooling

technical field

The invention relates to the technical field of fixtures, in particular to a positioning fixture used for drilling workpieces.

Background technique

Workpiece 1 as shown in Figure 1, it is an irregular annular workpiece, and also has groove, and its center hole 11 is ellipse, also has arc surface 12 on the workpiece 1, will be on arc surface 12 now. It is difficult to process the through hole 13 perpendicular to the arc surface 12, and it is difficult to use ordinary fixtures to locate it. In particular, to ensure the machining accuracy, special tooling must be used to meet the requirements, and the tooling must be easy to use and high in clamping efficiency. At the same time, the machining accuracy can be guaranteed.

Contents of the invention

Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a double-hole positioning tool for arc surface drilling, which has a simple structure, flexible and convenient use, high clamping efficiency and high machining accuracy.

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

Arc surface drilling double hole positioning tooling, including trapezoidal table, with L-shaped positioning table on the trapezoidal table, positioning column on the positioning table, and rectangular block on the outer circle of the positioning column; the positioning table is an arc surface above the positioning column , the positioning table has a drilling mold in the normal direction of the arc surface; the trapezoidal table is located below the positioning column with a chute, and a dovetail table is installed in the chute, and the dovetail table is fixedly connected to the bottom of the U-shaped bracket. with screws on both sides.

The advantages of the present invention are: according to the structure of the workpiece, the positioning column is provided on the positioning platform to match the central hole of the workpiece, and at the same time, a bracket is provided on the trapezoidal platform, and the screws on it clamp the slot on the workpiece. Set the arc surface, and install the drilling mold in the normal direction of the arc surface, drill holes on the arc surface of the workpiece through the drilling mold, and tilt the trapezoidal table to the left and right directions to efficiently process double holes, without the need to carry out work on the workpiece Repeated clamping and positioning, simple structure, flexible and convenient use, high clamping efficiency and high machining accuracy.

detailed description

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

As shown in Figures 1 to 2, the present invention comprises a trapezoidal platform 2, an L-shaped positioning platform 3 is provided on the trapezoidal platform 2, and a positioning column 4 is provided on the positioning platform 3, and the central slotted hole on the positioning platform 4 and the workpiece 1 11 cooperation, the outer circle of the positioning column 4 has a rectangular block 5, during processing and positioning, the slot of the workpiece 1 is clamped on both sides of the rectangular block 5; the positioning table 3 is located above the positioning column 4 as an arc surface, and the arc The radian of the surface is the same as the radian of the arc surface 12 on the workpiece 1. During processing timing, the arc surface 12 of the workpiece 1 can be close to the arc surface on the positioning table 3, and the arc surface 12 on the positioning table 3 can be positioned on the arc surface. The normal direction of the surface has a drilling template 6. When the arc surface 12 of the workpiece 1 is attached to the arc surface of the positioning table 3, a through hole 13 perpendicular to the arc surface 12 can be processed; There is a chute 7 under the positioning column 4, and a dovetail table 9 is installed in the chute 7, and the dovetail table 9 is fixedly connected to the bottom of the U-shaped bracket 8, and screws 10 are provided on both sides of the bracket 8, and the U-shaped bracket 8 can be attached to the dovetail. The table 9 moves horizontally along the chute 7, and when the U-shaped bracket 8 moves below the positioning column 4, the screw 10 can be tightened to clamp the slot on the workpiece 1 to the rectangular block 5, and the workpiece 1 can be clamped accurately When positioning and drilling, first contact an inclined surface of the trapezoidal table 2 with the operating table, and one of the drilling templates 6 is in a vertical state to complete the processing of the first hole. In the same way, the second hole can be completed. Processing, high efficiency, high processing precision;

The using method of the present invention is as follows:

The first step is to match the central slotted hole 11 of the workpiece 1 with the positioning table 4;

In the second step, the grooved part of the workpiece 1 is clamped on the rectangular block 5;

The third step is to adjust the position of the U-shaped bracket 8, and tighten the screw 10 to clamp the slotted part of the workpiece 1 on both sides of the rectangular block 5;

In the fourth step, an inclined surface of the trapezoidal table 2 is first contacted with the operating table, and one of the drilling templates 6 is in a vertical state to complete the processing of the first through hole 13. In the same way, the second through hole 13 can be completed processing.

The above description is an explanation of the present invention, not a limitation of the invention. For the limited scope of the present invention, please refer to the claims. Within the protection scope of the present invention, any form of modification can be made.
