Automatic torque detection system and detection method for flexible transmission shaft

Abstract

The invention discloses an automatic torque detection system and method for a flexible transmission shaft, and the system comprises an operation table, the front and rear sides of the top of the operation table are fixedly provided with sliding rails, the tops of all the sliding rails are slidably provided with an adjusting seat, and the left side wall of the adjusting seat is provided with a first limiting assembly. A servo motor is fixedly arranged on the right side wall of the adjusting seat, the driving end of the servo motor penetrates through the adjusting seat and is fixedly connected with a torque sensor, the other end of the torque sensor is fixedly connected with a first limiting assembly, and a positioning seat is fixedly arranged on the left side of the top of the operation table; a second limiting assembly is fixedly arranged on the right side wall of the positioning seat, and relates to the field of transmission shaft detection, the transmission shaft detection device comprises an operation table, and the distance between an adjusting seat and the positioning seat can be changed according to transmission shafts with different lengths by arranging the movable adjusting seat, so that the transmission shaft detection device can adapt to the transmission shafts with various lengths; and the practicability of the transmission shaft torque detection system is improved.

Description

technical field [0001] The invention relates to the technical field of transmission shaft detection, in particular to an automatic torque detection system and detection method of a flexible transmission shaft. Background technique [0002] The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial. Generally, the drive shaft must be tested for dynamic balance before leaving the factory, and adjusted on the balancing machine. For front-engine rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the final reducer, which can be several sections, and the joints can be connected by universal joints. In the production process, the transmission shaft needs to go through multiple testing experiments, among which torque testing is an indispensable testing item. [0003] However, the current device for detecting the torque of the drive shaft is generally only suitable for a single-length drive shaft. Sinc...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic torque detection system and detection method for a flexible transmission shaft, which solves the problem that the current device for detecting the torque of a transmission shaft is generally only applicable to a transmission shaft of a single length, and has a small application range and practicality. Low performance cannot meet the torque detection of different models and the traditional drive shaft is connected to the detection device through a large number of bolts, which consumes a lot of detection time and greatly reduces the detection efficiency
