Large-diameter end cover propelling mechanism, assembling method and press-fitting tightening equipment

Abstract

The invention discloses a large-diameter end cover propelling mechanism, an assembling method and press-fitting tightening equipment. The large-diameter end cover propelling mechanism comprises a press-fitting assembly and a positioning assembly, the press-fitting assembly provides propelling force to propel an end cover to enter a press-fitting end of a barrel, the press-fitting assembly comprises a press-fitting motor, a connecting screw and a screw block, one end of the connecting screw is connected with a power output shaft of the press-fitting motor, and the other end of the connecting screw is connected with the screw block; and the positioning assembly is used for fixedly connecting an end cover positioning seat and the barrel and comprises an end plate and the end cover positioning seat, the end plate is located at one end of the barrel, a through hole for the end cover and the end cover positioning seat to penetrate through is formed in the center of the end plate, and a positioning insertion block for integrally connecting the end cover positioning seat and the barrel is installed on the end plate on the outer edge of the through hole. The large-diameter end cover propelling mechanism has the advantages that the end cover can be automatically grabbed, a tool can be automatically placed, the tool can be automatically propelled and jacked, meanwhile, threaded parts can be automatically centered, automatic assembly is achieved under the condition that the coaxiality is guaranteed, manpower is reduced, the labor intensity is lowered, and therefore the working efficiency is improved.

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...
