Metering shell press sealing system of diaphragm gas meter

Abstract

The invention belongs to the field of gas meter production equipment, and discloses a metering shell press sealing system of a diaphragm gas meter. The metering shell press sealing system of the diaphragm gas meter comprises a rack, a rotary index plate and a press sealing machine, wherein the rotary index plate and the press sealing machine are arranged on the rack. The rotary index plate is provided with movement body positioning seats evenly distributed in the circumferential direction of the rotary index plate. A secondary positioning mechanism and a metering shell mechanical arm are arranged on one side of the rotary index plate. The secondary positioning mechanism comprises an overturning plate and a profiling tool which are arranged in a one-to-one correspondence manner. The overturning plate is provided with an overturning air cylinder and used for receiving a metering shell with an upward opening, the profiling tool is located on one side of the overturning plate, the shape of the profiling tool is matched with that of the metering shell, and the profiling tool is used for receiving the metering shell with a downward rotating opening of the overturning plate. The movement body positioning seats are used for containing movement bodies, and the metering shell mechanical arm is used for transferring the metering shell on the profiling tool and buckling the metering shell to the movement bodies. Press sealing is finished in the manners of shaping, expanding and pre-tightening, the buckling and even riveting press sealing efficiency of the metering shell and the movement bodies is effectively improved, and production faults and the like are reduced.

Description

Technical field [0001] The present invention belongs to the field of production gas meter equipment, particularly relates to a membrane type gas meter casing packer metering system. Background technique [0002] Diaphragm gas meter is widely used in urban construction, has a large market demand, so as to improve production efficiency, now on the market usually assembled automated assembly line, as in Patent No. "201710078125X", and entitled "an Patent gas meter movement and assembly method of assembling an automatic production line ", i.e. discloses a corresponding automated assembly line production, which involves the step of crimping the metering housing, when caulking need to first metering body with the movement of the positive shell, and entangled with each other in pose, i.e., the teeth on the rivet shell in the circumferential movement of the metering member to the outside, however, applicant has found that in a subsequent process embodiment, since the movement of the mete...
