Abstract

The utility model relates to a tooling, in particular to a part punching tooling convenient in positioning. The part punching tooling is characterized in that a tooling body is a hexagonal column, deep holes are arranged on each two column surfaces which are spaced pairwise, and high-hardness drilling die sleeves are arranged in the deep holes, so that the tooling body is divided into three equal parts rightly. A positioning hole used for positioning parts is arranged in the tooling body longitudinally, and is provided with chip removal grooves longitudinally corresponding to the high-hardness drilling die sleeves. Projections used for fixing parts are longitudinally arranged on the circumference of the center hole. Compared with the prior art, the part punching tooling has the advantages of simplicity in manufacturing, convenience and easiness in operation, high machining efficiency, low machining cost and the like.

Description

Part punching frock

Technical field

The utility model relates to a kind of frock, a kind of specifically punching frock of being convenient to the part location.

Background technology

The same industry is bored the trisection hole as needing on cylindrical part at present, and general most employing calibration catching plate carries out clamping to part, but because the calibration catching plate costs an arm and a leg, complicated operation, and working (machining) efficiency is low, and corresponding processing cost is also high.

Summary of the invention

The utility model provides a kind of simple in structure, easy and simple to handle in order to overcome the deficiency of prior art, and punching frock with low cost.

To achieve these goals; The utility model has designed a kind of part punching frock; It is characterized in that: the frock main body is the hexagon cylinder, and offers deep hole and high rigidity drill jig cover is set in deep hole on separately the cylinder in twos, just in time the frock main body is divided into trisection; The frock main body is longitudinally offered the locating hole that is used for locating element, and chip area is longitudinally offered in the position of the corresponding high rigidity drill jig cover of locating hole; The circumference of centre bore longitudinally is provided with the convexity that is used for fixing part.

Said convexity is an arcuate structure.

Be provided with lower counterbore between said locating hole and the frock main body upper surface, lower counterbore and locating hole interconnect, and the diameter of lower counterbore is greater than locating hole.

Advantages such as the utility model is compared with prior art, and it is simple, easy and simple to handle to have a frock making, and working (machining) efficiency is high, and processing cost is low.

Referring to Fig. 1 to Fig. 5,1 is the frock main body; 2 is high rigidity drill jig cover; 3 is locating hole; 4 is protruding; 5 is lower counterbore; 6 is chip area; 7 is part; 8 is the hole; 9 is groove.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Like Fig. 1, Fig. 2 and shown in Figure 3, the punching frock main body 1 of the utility model is the hexagon cylinder, and offers deep hole and high rigidity drill jig cover 2 is set in deep hole on separately the cylinder in twos, just in time frock main body 1 is divided into trisection; Frock main body 1 is longitudinally offered the locating hole 3 that is used for locating element, also is provided with lower counterbore 5 between locating hole 3 and frock main body 1 upper surface, and lower counterbore 5 interconnects with locating hole 3, and the diameter of lower counterbore 5 is greater than locating hole 3.Chip area 6 is longitudinally offered in the position of locating hole 3 corresponding high rigidity drill jig covers 2; The circumference of locating hole 3 longitudinally be provided with part 7 on the arc convex 4 that is complementary of groove 9.

It is as shown in Figure 4 when frock is used part to be put into the locating hole 3 of frock main body 1; The arc convex 4 at locating hole circumference place just in time is embedded in the arc groove 9 of part 7; Fix through protruding 4 pairs of parts 7, prevent the rotation of part in the punching process, the high rigidity drill jig cover through being positioned at the frock side face is to part 7 processing of holing then; Bullport through in the drill jig cover can be found the machining hole center automatically accurately, and adding the chip that produces man-hour can discharge through chip area 6.After having beaten a hole, only need the upset frock just can process second hole, need not again part to be taken out in frock, so not only easy to process, and also machining accuracy can be protected.

Part after the processing is as shown in Figure 5, and hole 8 is that the frock through the utility model processes.
