Abstract

This utility model proposes a positioning fixture for assembling a gas meter housing, relating to the field of diaphragm gas meter housing assembly technology. It includes an upper housing and a lower housing. The upper housing is provided with an inlet pipe and an outlet pipe with external threads. It also includes an assembly table, a first positioning frame, a lifting assembly, a mounting plate, a first through hole, a second through hole, a second positioning frame, and a nut. This application can accurately define the upper and lower housings of the gas meter sequentially. Then, by automatically lowering the upper housing, the accurate assembly of the gas meter housing can be completed in one go, without deviation and thus without rework. The assembly and positioning effect of the gas meter housing is better, and the device structure is simple and easy to operate.
