Pulling-out force test platform for gear selecting and shifting flexible shaft guide pipe

Abstract

The invention provides a pulling-out force test platform for a gear selecting and shifting flexible shaft guide pipe. The pulling-out force test platform comprises a base, wherein a set of rectangularblocks distributed in a cross shape are arranged on the base, and threaded holes are formed in the rectangular blocks; a fixedly connected servo motor is mounted on the base, and a rotationally connected mounting block A is mounted on the base; the flexible shaft comprises a steel wire rope, the steel wire rope is clamped to the mounting block A, the other end of the steel wire rope is clamped tothe mounting block B, and the steel wire rope is sleeved with the flexible shaft. The platform is advantaged in that the tension detection structure of the steel wire rope is improved, the steel wirerope is installed through the U-shaped grooves formed in the installation block A and the installation block B, the air cylinder B is arranged at the bottom of the installation block B, and the air cylinder B is controlled to move downwards to drive the installation block B to move downwards to pull the steel wire rope to tension and detect tension; and when the mounting block B moves downwards,the digital display push-pull device can display the tension of the steel wire rope and the application time of the steel wire rope.

Description

technical field [0001] The invention belongs to the technical field of flexible shaft guide tubes, and more specifically relates to a test platform for pull-off force of a flexible shaft guide tube for gear selection and shifting. Background technique [0002] The flexible shaft guide tube is a collection of related components that provide the guiding function for the reactor control rods. In the production process of selecting the shift flexible shaft, in order to ensure that the pull-off force of the guide tube of the produced product meets the design requirements, it is necessary to perform a pull test on it. The shaft clamp is fixed, and the force required by the specification is applied to one end of the guide tube for testing. [0003] Based on the above, when the existing tensioner detects the pulling force of the steel wire rope, it is necessary to apply the pulling force detected by the guide tube on the tensioner. The magnitude, time and angle of the applied force ...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a pull-off test platform for the guide tube of the flexible shaft for shifting gears, to solve the problem that when the existing tensioner detects the tension of the wire rope, it is necessary to apply the tension detected by the guide tube on the tensioner, the magnitude of the applied force, The time and angle are manually controlled, and the applied force is not well controlled, resulting in large errors. The applied time and the angle of rotation cannot be effectively controlled. When the flexible shaft is fixed, the clamp is fixed with bolts, which is laborious during operation. question
