Description

Tooling for efficient drilling

technical field

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

Background technique

Work piece 13 as shown in Figure 1, it has the bottom 14 of rectangle, and the two ends of bottom 14 all have an L-shaped boss 15, will process through hole 16 at the bottom of boss 15 now, use common fixture to Its positioning is difficult, especially in order to ensure the machining accuracy, special tooling must be used to meet the requirements, and the tooling must be easy to use, high in clamping efficiency, and at the same time ensure its machining accuracy.

Contents of the invention

Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a tool for high-efficiency drilling, which has a simple structure, flexible and convenient use, high clamping efficiency and high processing precision.

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

Tooling for high-efficiency drilling, including the base, the top of the base has a threaded hole and is fixed to the L-shaped support block, the L-shaped support block has a U-shaped support, and the drilling template with two supports is connected to the U-shaped support through the positioning pin Pivot connection, with drilling jigs and grooves on the two brackets; the pressure plate is pressed tightly on the two brackets through bolts and threaded holes; there is a right-angle notch at one corner of the base, and the notch is close to the base The positioning plate is fixedly connected on the side wall, and a screw rod is installed on the positioning plate.

The advantages of the present invention are: according to the specific structure of the workpiece, a matching structure is provided on the base, and a reversible drilling mold frame is pivotally connected on the base. The drilling mold frame not only has a drilling mold but also has a rectangular The matching groove at the bottom completely matches the workpiece. The workpiece is clamped and positioned vertically and horizontally by the pressure plate and the positioning plate. The structure is simple, the use is flexible and convenient, the clamping efficiency is high, and the processing accuracy is high.

Figure 1 is a schematic diagram of the structure of the workpiece.

Fig. 2 is a structural schematic diagram of the present invention.

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 and 2, the present invention includes a base 1, the top of the base 1 has a threaded hole 2 and is fixedly connected with an L-shaped support block 4, and the L-shaped support block 4 has a U-shaped support 7 with two brackets The drilling template 6 is pivotally connected with the U-shaped support 7 through the positioning pin 8, and the workpiece 13 can be installed or disassembled by turning over the drilling template 6. Both of the supports have a drilling template 3 and a groove 9. For the workpiece 13 After positioning, the positions of the two drilling templates 3 correspond exactly to the positions of the through holes 16 to be processed on the workpiece 13, and the groove 9 is used to match the rectangular bottom 14 of the workpiece 13, so that the drilling template 6 can be completely matched with the workpiece. 13, to achieve vertical precise positioning of the workpiece 13; the pressure plate 5 is pressed on the two supports through the bolt and the threaded hole 2, and then the workpiece 13 is pressed on the base 1; one corner of the base 1 has a Right-angle notch 10, right-angle notch 10 matches with the L-shaped boss 15 on the workpiece 13, on the base 1 near the sidewall of breach 10, fixes positioning plate 11, and screw rod 12 is installed on the positioning plate 11, and rotation screw rod 12 can From the side wall of the boss 15 on the workpiece 13, the workpiece is pressed on the base from the horizontal direction;

The using method of the present invention is as follows:

In the first step, the workpiece 13 is placed on the base 1;

In the second step, the two L-shaped bosses on the workpiece 13 are respectively matched with the side wall of the base 1 and the right-angle notch 10, and the rectangular bottom 14 of the workpiece 13 is matched with the grooves on the two supports of the drilling template 6 9 cooperation;

In the third step, the bolts are used to press the pressing plate 5 onto the workpiece, and then vertically press the workpiece onto the base 1;

In the fourth step, turning the screw 12 will press the L-shaped boss 15 on the workpiece 13 to the right-angle notch 10 of the base 1 from the horizontal direction;

In the fifth step, the through hole 16 is processed on the workpiece 13 through the drilling template 3 .

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.
