A large-diameter end cover propulsion mechanism, assembly method, and press-fitting and tightening equipment

Abstract

The invention discloses a large-diameter end cover propulsion mechanism, assembly method, and press-fitting and tightening equipment, including a press-fit assembly, which provides a driving force to push the end cover into the press-fit end of the barrel, which includes a press-fit motor, a connecting screw and Screw block, one end of the connecting screw is connected to the power output shaft of the press-mounted motor, and the other end is connected to the screw block; the positioning component is used for the fixed connection between the end cover positioning seat and the cylinder, including the end plate and the end cover positioning seat. The end plate is located at one end of the cylinder, and a through hole for the end cover and the end cover positioning seat to pass is formed at the center of the end plate, and the end plate on the outer edge of the through hole is installed for realizing the end cover positioning seat and The positioning insert block is integrally connected with the cylinder; this device can realize the automatic grabbing of the end cap, automatically put it into the tooling, the tooling will automatically push and tighten, and at the same time, it can realize the automatic centering of the threaded parts. Realize automatic assembly, reduce labor and labor intensity, thereby improving work efficiency.

Description

technical field [0001] The invention belongs to the technical field of assembly of large-diameter cylinder end caps, and in particular relates to a large-diameter end cap propulsion mechanism, an assembly method, and press-fitting and tightening equipment. Background technique [0002] In the production operation, a large-caliber cylinder is encountered. Because it has two ends, during the processing, one end of the cylinder needs to be pressed and pushed with a large-diameter end cap, and the other end of the cylinder is formed with an inner thread opening. Carry out the tightening of large-diameter screw parts. Therefore there are following problems: one, the assembly of the large-diameter end cap, because the end cap has a large weight and a large caliber, it is difficult for workers to operate, so two people are required to work at the same time, one is responsible for lifting the end cap, and the other is responsible for advancing the cylinder body. It is difficult for...

Problems solved by technology

Therefore there are following problems: one, the assembly of the large-diameter end cap, because the end cap has a large weight and a large caliber, it is difficult for workers to operate, so two people are required to work at the same time, one is responsible for lifting the end cap, and the other is responsible for advancing the cylinder body. It is difficult for two people to work together, and the end cover and the cylinder are sealed by an O-ring, so when assembling, the coaxiality between the end cover and the cylinder must be ensured to prevent the O-ring from being damaged and affecting the sealing effect

There are many ways to realize the tightening of conventional small-diameter screw parts, but it is difficult to guarantee the coaxiality of large-diameter screw parts
