Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a steering intermediate shaft angle measuring device, which solves the above-mentioned background technology that currently adopts grating encoders or encoder discs that are cumbersome to install, inconvenient to disassemble, require high positional accuracy, and are expensive. The high-precision encoder and code disc are glass structures, which are easily damaged during disassembly and assembly, and the encoder and code disc are expensive, and most of the parts have thicker diameters at both ends and thinner diameters in the middle, sliding sub-splines, sliding sub-spline sleeves The position cannot be installed with an encoder or a code disc at all, and it is impossible to test the clearance of the intermediate shaft subassembly

Abstract

The invention discloses a steering intermediate shaft angle measuring device, and relates to the technical field of steering intermediate shafts. The steering intermediate shaft angle measuring device comprises a supporting beam and linear guide rails which are located at the two ends of the supporting beam and are perpendicular to the central axis of the supporting beam, and one end of each linear guide rail is provided with a sliding block matched with the corresponding linear guide rail in size. Rotation angles of all parts of a steering transmission shaft assembly are output through a swing arm, a grating displacement sensor with a spring reset function is pushed to move through swing of the swing arm, swing of the swing arm is converted into displacement of the grating displacement sensor, and the swing angle of the swing arm is calculated through mathematical calculation, so the swing angle of a test point is calculated. The torsion angle gap of each combination point of the transmission shaft assembly is calculated through the difference value of the swing angle of each point, and angle detection is converted into linear displacement detection, so that the detection operation is facilitated, the detection cost is reduced, the detection efficiency is improved, the detection result is amplified, and the detection error is reduced.

Description

technical field [0001] The invention relates to the technical field of radar parts production, in particular to a steering intermediate shaft angle measuring device. Background technique [0002] With the improvement of component requirements in the steering industry, higher requirements are put forward for the test of the sub-assemblies of the intermediate shaft assembly after the assembly is completed. After the assembly of the intermediate shaft is completed, the total component assembly (including the joint assembly, sliding sub-assembly, and lower universal joint assembly), this clearance detection is realized by detecting the rotation angle of the steering intermediate shaft. [0003] At present, grating encoders or code discs are cumbersome to install, inconvenient to disassemble, require high positional accuracy, and high prices. High-precision encoders and code discs are glass structures, which are easily damaged during disassembly and assembly, and the price of enc...
