Chassis ground clearance measuring tool

Abstract

The invention relates to a chassis ground clearance measuring tool, and belongs to the technical field of automobile design and manufacturing. The chassis ground clearance measuring tool comprises a base, a measuring rod assembly and a telescopic rod assembly. The base comprises a horizontal base plate, the middles of the two sides of the horizontal base plate are each provided with a long hole extending in the Y direction, the long holes in the two sides are each internally provided with a measuring rod assembly, and each measuring rod assembly is provided with a telescopic rod assembly. Themeasuring rod assembly comprises a measuring rod, a pressure spring, a spring seat, a gasket and two locking nuts. The telescopic rod assembly comprises a sleeve, a switch shaft, a switch framework and a switch body. According to the measuring tool, the height of the measuring rod can be adjusted according to vehicle model parameters to be measured, only the measuring rod needs to be moved to theposition of the cam shaft in the Y direction, whether the top of the measuring rod coincides with a measuring point is observed, the tool does not need to be withdrawn when the ground clearance of thechassis is adjusted, measurement can be conducted while adjustment is conducted, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, and more specifically, the invention relates to a tool for measuring the height of the chassis from the ground. Background technique [0002] In the prior art, the method for most automobile manufacturers to adjust the height of the chassis from the ground is: people stand in the pit and use a scaled tooling or tool (such as a ruler) to measure, because the measurement reference plane (Z direction) and the measurement tool The consistency of the angle with the ground is difficult to guarantee, resulting in large measurement errors (including unilateral errors and height differences on both sides). In addition, because the measurement point (generally the center of the camshaft or the head of the cam bolt) is far away from the personnel's line of sight, in order to ensure the measurement accuracy, the scale on the measuring tool is small, and it is difficult for personnel...

[0002] In the prior art, the method for most automobile manufacturers to adjust the height of the chassis from the ground is: people stand in the pit and use a scaled tooling or tool (such as a ruler) to measure, because the measurement reference plane (Z direction) and the measurement tool The consistency of the angle with the ground is difficult to guarantee, resulting in large measurement errors (including unilateral errors and height differences on both sides)

In addition, because the measurement point (generally the center of the camshaft or the head of the cam bolt) is far away from the personnel's line of sight, in order to ensure the measurement accuracy, the scale on the measuring tool is small, and it is difficult for personnel to observe, which further increases the occurrence of measurement errors and affects subsequent operations. Detection and dynamic debugging one-time pass rate

Aiming at the existing problems at present, a measuring tool is designed, which can solve the problem of large measurement error and difficult operation at the same time
