Abstract

The invention belongs to the technical field of transmission assembly and particularly relates to a transmission countershaft key and pin full-automatic press-fitting unit comprising a body, a press-fitting device, an elastic cylindrical pin separating mechanism, an elastic cylindrical pin conveying mechanism, a key feeding mechanism, and a key conveying mechanism; the press-fitting device, the elastic cylindrical pin separating mechanism, the elastic cylindrical pin conveying mechanism, the key feeding mechanism and the key conveying mechanism are mounted on the body. A plurality of elastic cylindrical pins to be press-fitted are separated by the elastic cylindrical pin separating mechanism and then fall into the elastic cylindrical pin conveying mechanism; the elastic cylindrical pin conveying mechanism conveys the elastic cylindrical pins to be above a transmission countershaft positioned on the body; the elastic cylindrical pins are press-fitted into pinholes of the transmission countershaft by the press-fitting device; keys to be press-fitted fall into the key conveying mechanism through the key feeding mechanism; the key conveying mechanism conveys the keys to be above the transmission countershaft; the keys are press-fitted into key grooves of the transmission countershaft by the press-fitting device. The transmission countershaft key and pin full-automatic press-fitting unit has the advantages that assembly precision is guaranteed, labor intensity is reduced for operators, and assembly efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of transmission assembly, in particular to a fully automatic press assembly unit for transmission intermediate shaft key pins. Background technique [0002] The square key and half round key are commonly used important parts on the intermediate shaft of the transmission. They mainly play the role of fixing the direction of the gear and transmitting torque. The elastic cylindrical pin prevents the axial movement of the square key and acts as an axial limiter. The press-fit assembly accuracy of two keys and one pin is directly related to the press-fit assembly accuracy of the intermediate shaft and the gear, as well as the work performance of the intermediate shaft in the transmission. The key pins of the existing intermediate shaft are assembled manually using a hand hammer, which not only cannot meet the assembly accuracy of the intermediate shaft, but also has a very high labor intensity for the operators. ...
