Method for using locating tool for high-accuracy drilling machining of rectangular block

Abstract

The invention relates to a method for using a locating tool for high-accuracy drilling machining of a rectangular block. The method comprises the following steps that the first step, a loading plate is inverted; the second step, a workpiece is put into a locating groove, and one end of the workpiece abuts against a locating pin; the third step, a boss on a locating block is arranged in the locating groove and presses the workpiece, and fixing holes correspond to threaded through holes; the fourth step, screws are installed in the threaded through holes and the fixing holes, so that the locating block and the loading plate are fixedly connected; the fifth step, the loading plate is upwards placed, and supporting legs are arranged on an operating platform in a supporting mode; the sixth step, a drill bit penetrates through a drill jig to conduct drilling machining on the workpiece. The locating tool for high-accuracy drilling machining of the rectangular block is simple in structure and high in machining accuracy, and flexible and convenient to use and easy to clamp.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to a fixture for drilling and positioning workpieces and a method for using the same. Background technique [0002] Such as figure 1 The workpiece 1 shown is rectangular, and two through-holes 11 are to be machined in its length direction, which can be realized by using ordinary fixtures. However, due to the relatively high accuracy and position requirements of the two through-holes 11, special It must be positioned by a specific fixture, and it must be easy to clamp to ensure production efficiency. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a high-precision drilling positioning tool for rectangular blocks and its use method, which has a simple structure, flexible and convenient use, high clamping efficiency and high processing precision. [0004] The technical scheme adopted in the pres...
