Problems solved by technology

[0005] However, the precision dimensions such as the valve seat of the valve housing are distributed on the lower end flange, and the machining can only be placed in the final process, and connected to the machine tool through the upper thin shaft, resulting in a large number of processed product valve seats and threads. Vibration lines, completely unable to meet the surface accuracy and shape and position tolerances required by the drawings

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Such as figure 2 As shown, the anti-chatter fixture for processing weakly rigid parts should realize the functions of positioning, clamping and anti-chatter. It consists of 4 fixing screws.

[0029] Such as image 3 As shown, the positioning plate 1 is mainly composed of a machine tool spindle connecting surface 7, a positioning end surface 9 (axial), a threaded connection hole 10, an inner hole guide surface 8, a flange and other structures. The co...

Abstract

The invention discloses an anti-flutter fixture for processing weakly rigid parts. The vibration problem is guaranteed, the surface quality and shape and position tolerance of the thread and valve seat are guaranteed, and the qualified rate reaches 95%, which enhances the sealing performance of the whole valve and greatly reduces the disassembly, repair and reinstallation caused by the unqualified valve sealing performance. The waste of manpower and resources caused by this process shortens the production cycle of the product.

Description

technical field [0001] The invention relates to mechanical processing and manufacturing technology, in particular to an anti-flutter jig for processing weakly rigid parts. Background technique [0002] The aerospace valve is an important component of the pressurized conveying system. It is a precision mechanical product for the launch vehicle to move after it goes to the sky. The valve parts have many cavities, complex structures, and high precision requirements. In recent years, with the rapid development of the aerospace industry, major engineering projects and key model tasks such as manned spaceflight, lunar exploration projects, and large-scale launch vehicles have been fully implemented, and the demand for rocket launches has grown rapidly, which puts higher demands on the output and quality of valve manufacturing. requirements. [0003] The sealing performance of valve products is the difficulty and key to the development, design and use of valves. The housing is a ...
