The invention provides a device for detecting the internal diameter of a cylinder sleeve, and the device comprises a transfer part, a guiding part and a measuring part, wherein the transfer part drives a detecting probe or the cylinder sleeve to move, and the detecting probe is provided with the guiding part and the measuring part. The transfer part comprises a horizontal movement mechanism, a vertical movement mechanism and a rotating movement mechanism. The guiding part includes at least two guiding strips, and the measuring part includes a pushing mechanism and a measuring sensor. The device provided by the invention solves a problem that the conventional mechanical transfer flexibility is insufficient through the flexible design of the transfer mechanism. Through the secondary positioning, the device avoids the transfer errors during the measurement, and employs a probe which is adapted to the inclination of the cylinder wall, thereby greatly reducing the measurement error. The telescopic guiding strips greatly improve the detection range and solve the problem of a small measuring range of high-precision measuring equipment.
Description
technical field [0001] The invention relates to an inner diameter detection device, in particular to a cylinder liner inner diameter detection device. Background technique [0002] As an important part of the inspection project in the production process, the inspection of the inner diameter of the cylinder liner has always been the focus and difficulty of inspection. At present, the detection methods are mainly divided into two categories: contact measurement and non-contact measurement. Common contact measurement methods have disadvantages such as slow measurement speed and easy scratches on the inner surface of the cylinder liner. The current non-contact measurement (laser sensor, etc.), because the outer surface and inner surface of the cylinder liner are non-finishing surfaces, and the bottom surface is uneven, etc., the measurement cannot be accurately calibrated, and the measurement accuracy and accuracy have great limitations. At the same time, it is impossible to r...
