The invention relates to an application method of a high-efficiency arched surface hole machining device. The application method comprises the following steps: (1) a positioning disc is fixed on a console; (2) a workpiece is put on two dowel pins in the horizontal direction for vertical limiting and supporting; and another dowel pin limits the workpiece in the horizontal direction; (3) a pressing plate tightly presses the workpiece on the end surface of the positioning disc by screws; (4) it judges if a through groove in the end surface of the positioning disc is in a horizontal state to judge if the positioning of the workpiece is precise; and (5) a through hole is machined in the arched surface of the workpiece. The application method has the advantages of simple structure, flexibility and convenience for use, simple clamping and high machining precision.
Description
technical field [0001] The invention relates to the technical field of fixtures, in particular to a positioning fixture for drilling workpieces and a method for using the same. Background technique [0002] Such as figure 1 The workpiece 6 shown has an arc surface. Now it is necessary to process the pin hole 7 on the arc surface. It is difficult to locate it with ordinary fixtures. In particular, to ensure the machining accuracy, special tooling must be used. In order to meet the requirements, the tooling must be easy to use, high in clamping efficiency, and at the same time ensure its machining accuracy. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a high-efficiency curved surface machining device and its use method, which has a simple structure, flexible and convenient use, high clamping efficiency and high machining accuracy. [0004] The technical scheme adopted in the present invention...
