Problems solved by technology

[0002] Existing engine piston protruding height measurement devices are all measured by a single displacement sensor, because the measured workpiece (engine) has poor positioning consistency, causing the reference zero position of the displacement sensor to be inconsistent with the workpiece plane zero position during measurement. A single point leads to low accuracy of measurement results

Abstract

The invention discloses a piston protruding height measuring device and a using method thereof. The piston protruding height measuring device comprises a power device, a fixing plate and a sensor, wherein the power device is connected with the fixing plate. The piston protruding height measuring device further comprises a measuring plate, a spring and a supporting stud, wherein the measuring plateis connected directly under the fixing plate by the supporting stud; the spring is disposed between the fixing plate and the measuring plate and sleeved on an outer side of the supporting stud; the supporting stud is spaced from the connection between the fixing plate and the measuring plate; and the sensor is fixed to the measuring plate. The piston protruding height measuring device has the advantages of compact structure, accurate positioning and high measurement efficiency.

Description

technical field [0001] The invention relates to the field of engine manufacturing, in particular to a piston protrusion height measuring device and a method for using the same. Background technique [0002] Existing engine piston protruding height measurement devices are all measured by a single displacement sensor, because the measured workpiece (engine) has poor positioning consistency, causing the reference zero position of the displacement sensor to be inconsistent with the workpiece plane zero position during measurement. A single point leads to low accuracy of measurement results. [0003] The disclosure of the above background technical content is only used to assist in understanding the concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application. If there is no clear evidence that the above content has been disclosed on the filing date of this patent application In some cases, the above back...
