Automatic assembly method and assembly line for movement of diaphragm gas meter

Abstract

The invention belongs to the field of gas meter production equipment, and discloses an automatic assembly method and assembly line for a movement of a diaphragm gas meter. The assembly method mainly comprises the steps of automatic press sealing of a metering shell and automatic assembly of a connecting rod. In the automatic press sealing of the metering shell, secondary positioning of the metering shell and expansion of riveting teeth of the metering shell are conducted firstly; and then the metering shell with the expanded riveting teeth and a movement body are aligned and buckled and then are riveted in a press sealing manner. In the automatic assembly of the connecting rod, the position of a pointer disc assembled on the movement body is adjusted firstly, a fixing head of the connecting rod on the pointer disc is located on the side away from a rocker arm on the movement body, then after the pointer disc and the rocker arm are fixed, the two ends of the connecting rod are connected with the rocker arm and the pointer disc respectively, and the assembly line is mainly achieved on the basis of the assembly method. A pre-adjusting assembly concept is adopted, the buckling and even riveting and press sealing efficiency of the metering shell and the movement and the connecting rod assembly efficiency are effectively improved, production line faults and errors are reduced, the production efficiency of the gas meter movement is improved, and the assembly line cost is reduced.

Description

technical field [0001] The invention belongs to the field of gas meter production equipment, and in particular relates to an automatic assembly method for a diaphragm gas meter core and an assembly line thereof. Background technique [0002] Membrane gas meters are widely used in urbanization construction and have a large market demand. Therefore, in order to improve their production efficiency, automatic assembly lines are usually used in the market for assembly. For example, the patent number is "201710078125X", and the patent name is "a kind of Gas Meter Movement Automatic Assembly Method and Assembly Production Line" patent discloses the corresponding automatic assembly production line, which involves the riveting process of the metering shell. When riveting, the metering shell and the movement body need to be aligned first. and are in a mutual engagement posture, that is, the riveting teeth on the metering shell are located on the circumferential outside of the movement...
