Lubricating medium coating mechanism of direct drive assembly device

Abstract

The invention discloses a lubricating medium coating mechanism of a direct drive assembly device. The mechanism is characterized by comprising a shaft sleeve lubricating medium coating structure, wherein the shaft sleeve lubricating medium coating structure comprises a swing cylinder, a cantilever and a lubricating medium injector; a stationary flat plate located above the middle of an assembly rotation table is fixedly installed on an assembly table of the direct drive assembly device, and the lower end of the swing cylinder is fixed on the stationary flat plate and is close to a shaft sleeveassembly mechanism; a swing rod of the swing cylinder faces upward, and the cantilever is fixed on the swing rod; the outer end of the cantilever is lower than the upper end of the swing cylinder, avertically downward lubricating medium injector is fixedly installed at the outer end of the cantilever, a lubricating medium is stored in the lubricating medium injector, an injection port allowing the lubricating medium to flow out is formed in the lower end of the lubricating medium injector, and the injection port can enter and contact with the inner bottom of a shaft sleeve on an assembly seat of the direct drive assembly device, and is used for injection of the lubricating medium. The lubricating medium coating mechanism of the direct drive assembly device has the advantages of being simple to control and compact in structure.

Description

technical field

[0001] The invention belongs to the field of gas meters, and in particular relates to a lubricating medium coating mechanism of a direct transmission group assembly device. Background technique

[0002] The diaphragm gas meter is mainly composed of a metering part (including two metering boxes with flexible diaphragms inside each), a transmission part (including a diaphragm, a folding plate, a vertical shaft, a rocker arm, a connecting rod, a crank, a shift fork and a valve cover) ), counting part and housing.

[0003] The working principle of the membrane gas meter is: a diaphragm (usually made of synthetic rubber) is sealed at the center line of each metering box, and the diaphragm divides the inside of the metering box into two metering gas chambers. After the gas enters the gas meter, it alternately enters the two metering gas chambers of each metering box, so that the diaphragm (and the diaphragm clamped on the diaphragm) reciprocate, and then the linka...
