Cylinder sleeve detecting device

Abstract

The invention discloses a cylinder sleeve detecting device which comprises a base, a controller and a detecting chamber. A left side of the base is provided with the controller, a surface of the controller is provided with a display, and a lower part of the display is provided with a control button. An upper part of the base is provided with the detecting chamber, a lower part in the detecting chamber is provided with a working table, and an upper part of the working table is provided with a fixed table. A detecting column is provided with a data collector, a right side of the detecting chamber is provided a first hydraulic device, and a first crossbar is arranged on a side surface of the first hydraulic device. A second hydraulic device is arranged on a left side of the detecting chamber,a second crossbar is arranged on a side surface of the second hydraulic device, and side faces of the first hydraulic device and the second hydraulic device are provided with detecting plates which are internally provided with displacement sensors. According to the cylinder sleeve detecting device, by setting hydraulic devices on two sides of the detecting chamber, the hydraulic devices allow thefirst crossbar and the second crossbar to move forward, and the displacement sensors at front ends detect the surface flatness and roundness of a cylinder sleeve.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a cylinder liner detection device. Background technique [0002] The cylinder liner is generally made of wear-resistant alloy cast iron containing phosphorus or boron, such as HT25-47, HP-CuCrMo, etc. The inner surface of the cylinder liner is sometimes treated with chrome plating, nitriding or phosphating to improve wear resistance. The hardness of the inner surface of the cylinder liner is usually required to be greater than HB200, and has a good match with the hardness of the piston ring. The inner surface should also have appropriate roughness, so that it has a certain oil storage capacity and running-in performance. The inner surface and outer surface should have sufficient roundness and cylindricity accuracy, and the mounting support surface should have higher position accuracy in the center of the inner hole. [0003] Most of the cylinder liner bore size toler...

AI Technical Summary

Problems solved by technology

[0003] Most of the cylinder liner bore size tolerance measurement is manually measured by the inner diameter dial gauge. The measuring equipment is cheap and easy to operate, but it is very easy to cause artificial measurement errors and reading errors. The roundness is generally obtained by manual calculation. This method has low work efficiency and Existing testing equipment only detects the inner diameter, ignoring the accuracy and flatness of the cylinder liner outside
