X-type measuring device for compression height of vibration isolator of diesel engine set and use method of X-type measuring device

Abstract

Provided is a diesel engine set vibration isolator compression height X-type measuring device. The device comprises an upper body, a lower body, a first rivet shaft and a retainer, the upper body and the lower body are connected together through a first rivet shaft, the stop body and the lower body are fixedly connected together, and a stop pin capable of rotating around a second rivet shaft arranged on the stop body is clamped and fixed with or separated from the upper body; The first end of the upper body and the first end of the lower body are provided with measuring mechanisms used for representing the distance between the second end of the upper body and the second end of the lower body. The compression height of the vibration isolator is accurately measured through a reasonable device and an effective method, so that the adjustment data of the vibration isolator is more accurate and reliable.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to an X-type measuring device for the compression height of a vibration isolator of a diesel unit and a method for using it. Background technique [0002] Diesel generator set is composed of diesel engine, generator, vibration isolator and other components. After the diesel engine and the generator are connected together by a coupling, they are connected to the locomotive body through a vibration isolator. According to the performance requirements of the vibration isolator, the compression height of the vibration isolator needs to be measured after the diesel unit is installed on the locomotive, so as to adjust the vibration isolator according to the relevant data. Four point measurements are required for each isolator, such as figure 1 , it is necessary to measure the four points N1, N2, N3, and N4, that is, to measure the height between the processing surface of the lower end of th...

AI Technical Summary

Problems solved by technology

After the diesel generator set is installed on the locomotive, the surrounding space of the vibration isolator is extremely compact, and it is extremely difficult to measure the compression height. Since the compression height requires high precision, it is generally measured with a vernier caliper. For the four points to be measured N1, N2, N3, N4, where N2 and N3 can barely be measured, but N1 and N4 are extremely difficult to measure due to their location, often need to borrow additional auxiliary tools, and the measurement results are extremely inaccurate
