Cylinder body cylinder bore rabbet depth detection apparatus

Abstract

The invention discloses a cylinder body cylinder bore rabbet depth detection apparatus. The apparatus comprises a flat cylindrical positioning block adapted to the cylinder bore dimension of a cylinder body, a circular base whose external diameter is greater than the diameter of a rabbet of the cylinder body is arranged above the positioning block, the base is provided with a disk-form gauge seat capable of rotating around the circle center of the base, axles of the positioning block, the base and the gauge seat are superposed, and a stepladder-like positioning shaft connecting the positioning block, the base and the gauge seat is inserted to the center on the positioning block; and the periphery of one side of the gauge seat is provided with a handle used for controlling rotation of the gauge seat, and a measurement assembly is arranged at the side, opposite to the handle, of the gauge seat, is opposite to the rabbet of the cylinder body and is used for measuring the depth of the rabbet. The structure is simple, the operation is convenient, the depth of the whole ring of the rabbet of the cylinder bore of the cylinder body can be detected rapidly and convenient, the detection precision is high, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of engine measuring equipment, in particular to a cylinder block cylinder hole notch depth detection device. Background technique [0002] In the process of processing the cylinder block of the engine, the depth of the cylinder bore of the cylinder block is an important dimension of the cylinder block. If the size does not meet the process requirements, it will affect the installation of the steel sleeve, which may cause high water temperature of the whole machine, The phenomenon of backwater even leads to problems such as cracking of the steel sleeve, which brings great troubles to production. Therefore, after the completion of the cylinder bore seam processing of the cylinder block, it is necessary to detect the depth of the cylinder bore seam to determine the product quality.

Problems solved by technology

[0002] During the processing of the cylinder block of the engine, the depth of the cylinder bore of the cylinder block is an important dimension of the cylinder block. If the size does not meet the process requirements, it will affect the installation of the steel sleeve, which may cause high water temperature of the whole machine, The phenomenon of backwater even leads to problems such as cracking of the steel sleeve, which brings great troubles to production. Therefore, after the completion of the cylinder bore seam processing of the cylinder block, it is necessary to detect the depth of the cylinder bore seam to determine the product quality. Eligibility

At present, the measurement of the depth of the cylinder hole seam is generally carried out by three-coordinate measuring machines, detection platforms and height gauges. The measurement can only be carried out at the three-coordinate measuring machine or the detection platform. The logistics transportation distance is too long. Moreover, during the detection, it is necessary to level the cylinder block and find the reference point. This process is time-consuming and labor-intensive, so it is not applicable Because of batch testing, it restricts the production efficiency of enterprises
