Shaft fork detecting device for transmission shaft

Abstract

The invention provides a shaft fork detecting device for a transmission shaft. A tip is arranged perpendicularly upward the middle part of a bottom board. A stand post is arranged perpendicularly upward on a side edge of the bottom board and an adjustment slide table is arranged on the stand post. The adjustment slide table is provided with a V-shaped groove pointing to the bottom board. The bottom board, the stand post and the V-shaped groove form a semi-frame structure. The center of the V-shaped groove is aligned to the center of the tip. The adjustment slide table is provided with a detection instrument. According to the invention, by enabling a central hole of the tail part of a spline shaft of a shaft fork to be perpendicular and coaxial to a line of the center of the tip and to fit with the center of the V-shaped groove, the central line of the spline shaft of the shaft fork, the central line of a stiffening part of the shaft fork and the central line of a lug hole of the shaft fork are all enabled to perpendicular to a detection platform. Besides, the stability of the shaft fork is ensured and inclination is prevented. An effect similar to that the spline shaft of the shaft fork is mounted in a transmission shaft assembly is achieved, high-degree simulation is realized and the spline shaft is enabled to be coaxial with a shaft tube of the transmission shaft, a universal joint fork, a flange yoke and the like.

Description

technical field [0001] The invention relates to the detection field, in particular to a detection device for a transmission shaft and fork. Background technique [0002] In the transmission shaft of automobiles, the transmission shaft of medium and heavy vehicles is a key component in the transmission system. It has the characteristics of large transmission power and high load. It is subjected to large torque during the transmission process, resulting in large deformation and stress. [0003] The transmission shaft has vibration characteristics and anti-impact ability, but in the process of use, there are situations where the cross shaft and the fork head burn out and fail due to friction and heat generated by the bearing, and the parts break at the place of stress concentration. [0004] The shaft and fork of the transmission shaft and fork are relatively heavy during manual inspection, so the physical strength of the person is particularly difficult during the inspection, ...

[0003] The transmission shaft has vibration characteristics and anti-impact ability, but in the process of use, there are cases where the cross shaft and the fork head burn out due to friction and heat, and the parts break at the stress concentration.

[0004] The shaft and fork of the transmission shaft and fork are relatively heavy during manual inspection, so the physical strength of the person is particularly difficult during the inspection, and there are differences in the results of each inspection, such as: inspector inspection methods, positioning methods, inspection accuracy and accuracy will be affected
