Test tool for measuring height between center of synchronizer and junction surface of shell of gearbox

Abstract

The invention discloses a test tool for measuring the height between the center of a synchronizer and the junction surface of a shell of a gearbox. The test tool comprises a base, wherein the bottom surface of the base is adhered to the junction surface of the shell, a central spindle is arranged on the base, is axially provided with a detection plate in a sliding manner and passes through a mounting hole formed in a detection plate, and the measuring end of the detection plate is inserted into a synchronizer slot in the process of measuring. Therefore, the test tool can simply and quickly measure the height between the center of the synchronizer and the junction surface of the shell of the gearbox, so that the efficiency and reliability of the height measuring can be improved.

Description

technical field [0001] The invention relates to the technical field of component detection, in particular to a detection tool for measuring the height from the center of a gearbox synchronizer to the joint surface of a casing. Background technique [0002] The manufacturing accuracy and installation accuracy of the gearbox synchronizer will directly affect the smoothness of the gearbox shifting. If the manufacturing accuracy and installation accuracy of the gearbox are not high, shocks may be formed when shifting gears, and even a certain gear may appear. Therefore, during the gearbox assembly process, it is necessary to measure the height from the center of the gearbox synchronizer to the joint surface of the case. [0003] At present, traditional inspection tools are mostly used to measure the height, such as the combination of vernier calipers and height gauges or three-coordinate measurement. Specifically, such as figure 1 As shown, use a height gauge to measure the di...

Problems solved by technology

Specifically, as figure 1 As shown, use a height gauge to measure the distance L from the lower plane of the synchronizer to the joint surface of the housing, and then use a vernier caliper to measure the width B of the synchronizer, and use the value of L+B / 2 as the measurement value of the height; it can be seen that using the vernier caliper and The method of combining the height gauge to measure the above height is cumbersome. At the same time, the height gauge is too large to meet the requirements of online measurement conditions, and may interfere with the components of the gearbox assembly; while using the three-coordinate measurement method, it is necessary to change the The box assembly is sent to the three-coordinate measurement room for inspection, the process is cumbersome, labor-intensive, and measurement efficiency is low
