Problems solved by technology

However, in actual production, a micrometer is usually used for measurement. Due to the limitation of this maintenance tool, it is impossible to efficiently and accurately measure the surface of the traction pin, which not only restricts production efficiency, but also affects the quality of maintenance.

Abstract

The invention discloses a surface deformation detection device. The surface deformation detection device generally comprises a supporting frame, a dial indicator and two positioning pieces. The supporting frame comprises a first end, a second end and a middle portion located between the two ends, and the middle portion protrudes towards the first side. One positioning piece is located near the first end and protrudes out of the edge of the first end towards the second end, and the other positioning piece is located near the second end and protrudes out of the edge of the second end towards thefirst end. A sleeve of the dial indicator is fixedly installed in the middle of the supporting frame, and a measuring head of the dial indicator is arranged on the second side opposite to the first side of the supporting frame. And the measuring head of the dial indicator and the two positioning pieces are basically positioned on the same plane. The device and the mechanism are easy to operate, and the surface deformation detection of the part can be quickly and efficiently realized.

Description

technical field [0001] The invention relates to the field of defect detection, in particular to a surface deformation detection device and mechanism. Background technique [0002] After the locomotive has been in service for a period of time, its components need to be inspected and repaired. At present, some types of locomotives have been repaired. In this work, regarding the inspection and maintenance of the frame, it is required to overhaul the traction pin, spring seat, axle box tie rod seat, oil pressure shock absorber seat, brake hanger, motor hanger and other components. [0003] Among them, the maintenance requirements of the traction pin are not allowed to be deformed or cracked. During the maintenance of locomotive components, it is necessary to measure the surface condition of the traction pin. However, in actual production, a micrometer is usually used for measurement. Due to the limitation of this maintenance tool, it is impossible to efficiently and accuratel...
