Shell drilling and positioning tooling

Abstract

A shell drilling positioning fixture comprises a base which is provided with a first vertical leg and a second vertical leg perpendicular to one another. An upper cover plate of an L-shaped positioning seat covers and is fixed on part of the upper end face of the base, a vertical arm of the L-shaped positioning seat is parallel to the first vertical leg, the vertical arm is opposite to the first vertical leg in position, a supporting boss is arranged on a side wall, parallel and opposite to the second vertical leg, of the base, the lower end face of the upper cover plate, the upper end face of the supporting boss and the side wall form a positioning space for a to-be-drilled lug on a workpiece, and positioning holes corresponding to to-be-drilled positions of the to-be-drilled lug on the workpiece are formed in the upper cover plate. A positioning pin is arranged on each of the side face of the supporting boss, the side wall and the inner wall of the second vertical leg, and the multiple positioning pins are arranged sequentially from top to bottom and matched with pin holes in a positioning plate, a parallel clamping plate is arranged on the outer side of the first vertical leg, and bumps are arranged on the clamping plate and matched with grooves in the workpiece. The shell drilling positioning fixture is simple in structure, convenient to use and accurate and reliable in positioning.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a positioning tool for drilling workpieces. Background technique [0002] Such as figure 2 As shown, it is necessary to process a hole 63 on the protruding rod 62 of the side 61 of the workpiece 6. Since the side 61 where the protruding rod 62 is located is an inclined plane, although the general positioning tool can position it, the machining accuracy is difficult to guarantee, and the installation Clips are also cumbersome. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a casing drilling positioning tool, which has a simple structure, flexible and convenient use, and easy guarantee of positioning accuracy. [0004] The technical scheme adopted in the present invention is as follows: [0005] Shell drilling and positioning tooling, including a base, the base includes a vertical leg 1 and a vert...
