Ultrasonic detection device for automobile maintenance

Abstract

The invention belongs to the technical field of detection devices, and particularly relates to an ultrasonic detection device for automobile maintenance. The device comprises an ultrasonic probe; andthe ultrasonic probe is mounted on a rotating disc, a hemispherical mounting groove is formed in the bottom surface of the rotating disc, a driving ball is connected to the interior of the mounting groove, a driving groove is formed in the side wall of the driving ball, one side wall of the driving groove is arranged to be an inclined surface, a vent pipe communicated with the driving groove is arranged on the side wall of the mounting groove, and an air inlet cavity is formed in the outer side surface of the driving ball. The ultrasonic probe is mounted on the rotating disc, the rotating discrotates to drive the ultrasonic probe to completely detect the inner wall of an air cylinder, so the maintenance personnel can rapidly and accurately maintain the engine air cylinder; and meanwhile,deposited carbon on the inner wall of the air cylinder is blown off through the vent pipe on the rotating disc, so the ultrasonic detection device can also play a role in cleaning the interior of theair cylinder.

Description

technical field [0001] The invention belongs to the technical field of detection devices, in particular to an ultrasonic detection device for automobile maintenance. Background technique [0002] A car is a very convenient means of transportation. However, as the mileage continues to increase, the parts and assemblies in the car gradually lose their ability to work due to natural wear and other damage, especially the wear of the engine cylinder. The degree of wear of the cylinder will directly affect the power and economy of the engine, and the cylinder roundness and cylindricity errors are the main basis for determining whether the engine cylinder needs to be overhauled. Therefore, before determining whether the cylinder needs to be repaired, we must first detect The degree of cylinder wear. [0003] The traditional detection of cylinder wear can only be carried out when the engine is disassembled. This method is not only time-consuming and laborious, but also easily caus...

Problems solved by technology

[0003] The traditional detection of cylinder wear can only be carried out when the engine is disassembled. This method is not only time-consuming and laborious, but also easily causes damage to the engine due to improper disassembly. Not only the detection process is very complicated, but also its measurement accuracy and detection efficiency are relatively low
