Diesel engine connecting rod curvature measurer

Abstract

The invention discloses a diesel engine connecting rod curvature measurer which relates to a diesel engine connecting rod curvature measurer for an internal-combustion locomotive and mainly solves the problems inconvenient use, inaccurate measurement and influenced connecting rod repairing quality as the traditional diesel engine connecting rod curvature measurer can only measure the curvature of a connecting rod in one type due to self structural limitation and can not replace an abraded measurement rod. The diesel engine connecting rod curvature measurer comprises a measurement rod, a measurement regulation block, a dial indicator, a measurement reference block and a measurement column and is characterized in that a groove is arranged on the lateral surface of the top end of the measurement rod along the axial direction, and the measurement regulation block is fixed on the plane of the measurement rod through a screw rod connected to the groove of the measurement rod; and the measurement reference block fixed at the lower end of the measurement rod is in threaded connection with the measurement column. The measurement regulation block of the invention can be regulated and positioned according to requirements, and the measurement column can be replaced at any time, therefore, the operation is convenient, and the measurement accuracy is ensured.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a measuring instrument for the bending degree of a diesel engine connecting rod of a diesel locomotive. Background technique [0002] The structure of the known diesel engine connecting rod bending degree measuring instrument is that there are two screw holes on the left side of the top of the measuring rod, and the measuring adjustment block is measured with bolts, and the right side of the measuring rod is a plane whose size is consistent with the size of the side of the adjusting block. It is used to fix the adjusting block. Due to the limitation of the diesel engine connecting rod bending degree measuring instrument, it can only measure the bending degree of the connecting rod of DF4B diesel locomotive. With the increasing number of diesel locomotive models, the connecting rod models also have The difference between the two leads to inconvenience in the measurement process and inaccu...

AI Technical Summary

Problems solved by technology

[0002] The structure of the known diesel engine connecting rod bending degree measuring instrument is that there are two screw holes on the left side of the top of the measuring rod, and the measuring adjustment block is measured with bolts, and the right side of the measuring rod is a plane whose size is consistent with the size of the side of the adjusting block. It is used to fix the adjusting block. Due to the limitation of the diesel engine connecting rod bending degree measuring instrument, it can only measure the bending degree of the connecting rod of DF4B diesel locomotive. With the increasing number of diesel locomotive models, the connecting rod models also have The difference between the two leads to inconvenience in the measurement process and inaccurate measurement results, thus affecting the repair quality of the connecting rod; in addition, the measuring reference block and the measuring column of the measuring instrument are welded structures, because the measuring column is often in contact with the workpiece, and Its end is a small round surface, which is in approximate point contact with the working contact. It is easy to wear after frequent measurements and cannot be replaced.
