A processing tool and processing method for a multi-cavity product

Abstract

The invention provides a processing tool and a processing method for a multi-cavity product. The processing tool is designed according to the structural characteristics of the multi-cavity product. The processing tool includes a fixture body, a positioning pin and a connecting device, and the fixture body is a stepped circular structure. , the position of the axis on the big-end disc is set with a center hole, and eight threaded holes are processed on both sides of the center hole to match the process holes on the multi-cavity product; the positioning pin is a stepped circular structure, and the big end and the processing tooling Cooperate with the center hole on the top, and the small end extends out of the center hole to match the positioning hole on the multi-chamber product. During processing, use the positioning pin as a reference, cooperate with four sets of threaded connectors passing through the product process hole and the threaded hole of the processing tool to accurately locate the position of the inner cavity of the product. The invention can process four inner cavities with one set of tooling, which solves the problems of long positioning and alignment time, large repeated positioning error, low speed during processing and easy to cause product surface crushing in traditional processing methods, effectively improves production efficiency and Ensure product quality.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing tool and a processing method for a multi-cavity product. Background technique [0002] A multi-cavity product—the electric valve is one of the important components of the rocket engine. It is the main structural part of the combination of the fuel circuit and the air control circuit of the electric valve. It is composed of main and auxiliary valves. The valve body adopts a "ten" channel lumen structure, such as figure 1 and figure 2 shown. From the front view and B-B expanded view, it can be seen that the valve body has 4 complex inner cavities, in which the first inner cavity 1 and the second inner cavity 2 are auxiliary valve cavities, the third inner cavity 3 and the fourth inner cavity 4 are main valve cavities. cavity. According to the functional requirements of the valve, the first inner cavity 1 needs to be connected with the fou...
