Transmission shaft front section straightening mechanism adopting circlip groove to position

Abstract

The invention discloses a transmission shaft front section straightening mechanism adopting a circlip groove to position. The straightening mechanism mainly comprises a core rod assembly, a spring A,a spring B, a rotary shaft, a lughole, a round hole, an opening mechanism, a connecting rod and the circlip groove; the core rod assembly is inserted into the lughole, the rotary shaft is inserted into the middle of the core rod assembly, the spring B is arranged between the upper portion of the rotary shaft and the lughole and is arranged outside the core rod assembly in a sleeving mode, the round hole is formed in a platform below the core rod assembly, the connecting rod penetrates through the round hole, the opening mechanism is arranged through the connecting rod, and the opening mechanism is opened and embedded into the circlip groove in the lughole through the spring A which is arranged outside the connecting rod in a sleeving mode. According to the straightening mechanism, a welding fork and the middle fork lughole circlip groove are directly used as a positioning reference, a design reference is directly used as a straightening reference for straightening, and thus the straightening effect is more real, and the transmission and accumulative errors of parts are avoided; and the actual quality effect of the straightening process is improved, the beating requirement of a wholly assembled transmission shaft is guaranteed, and the overall quality of the transmission shaft is improved.

Description

technical field [0001] The invention relates to the field of transmission shafts, in particular to a front joint straightening mechanism of a transmission shaft positioned by a circlip groove. Background technique [0002] The existing straightening scheme of the front section of the transmission shaft is to use the center hole of the welding fork and the center hole of the spline shaft for positioning, and then use the straightening equipment to correct the runout T of the shaft tube to the range of the process requirements. Since the above-mentioned center hole is only the process reference of the spline shaft and welding fork, plus the spline fit error and the middle fork position error, even if the technical plan is corrected to the range of process requirements, the entire transmission shaft is assembled. After that, the overall beating still does not meet the requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the def...
