Problems solved by technology

Because the length dimension between the upper seam of the Z170 cylinder liner hole and the Huff surface of the body is 614 +0.10 0 It is a staggered dimension, the axis to be measured is not on the same line as the measuring reference axis of the measuring instrument, resulting in misalignment, which can only be detected by indirect measurement in the actual measurement process, resulting in low production efficiency and large measurement errors

Abstract

The invention is mainly applied to the field of diesel engine part detection and particularly relates to a machine body error surface size measurement device and method. The machine body error surfacesize measurement device comprises a measurement staff, a parallel plate and an equal-height gauge block; the measurement staff comprises a measurement rod; a fixed gauge frame and a movable gauge frame are respectively mounted at both ends of the measurement rod; corresponding to the movable gauge frame, a slideway is formed on the measurement rod; a gauge measurement head is mounted on the fixedgauge frame; a dial gauge is mounted on the movable gauge frame; the equal-height gauge block is set as a cylindrical measurement block; and the measurement rod, the gauge measurement rod and the dial gauge are all arranged in parallel. The machine body error surface size measurement device adopts a relative measurement detection method, follows the Abbe principle which is one of four basic measurement principles, can be directly used in inspection field, fills in one gap in the aspect of the measurement technology, is tried out in a machining workshop and is relatively ideal in effect.

Description

technical field [0001] The invention relates to a device and a method for measuring the size of an engine body staggered surface, which are mainly used in the field of detection of diesel engine components. Background technique [0002] The body is one of the most critical parts of the diesel engine, known as the skeleton of the diesel engine, and the inside of the body is processed with key dimensions such as the cylinder liner hole and the main bearing hole. The cylinder liner hole of the body is equipped with a cylinder liner, and the bottom end surface of the top of the cylinder liner is installed on the top port of the cylinder liner hole of the body. The main bearing hole of the body is composed of a bearing seat and a bearing cover. The main bush and crankshaft assembly, where the bearing seat contacts the bearing cover and divides the main bearing hole is called the Hough surface of the body. [0003] Taking the body of Z170 diesel engine as an example, the length t...
