Detecting device for detecting diameters of cylinders and inner diameters of round holes

Abstract

The invention discloses a detecting device for detecting the diameters of cylinders and the inner diameters of round holes. The detecting device comprises a support (1) and is characterized in that the support (1) is provided with a sliding block (2) capable of moving left and right along the support (1), the support (1) is further provided with a dial indicator which is capable of moving left and right and is matched with the sliding block (2), the support (1) and the sliding block (2) are provided with two measuring heads (3) respectively, and the two measuring heads (3) are matched. The detecting device is simple in structure, convenient to carry and operate, high in measuring efficiency and capable of ensuring the measuring accuracy. Detection can be conducted through the two measuring heads arranged on the support and the sliding block, in addition, the sliding block can move left and right, and therefore the inner diameters of the round holes with different diameters and the diameters of the cylinders can be detected through the two measuring heads. Meanwhile, measuring numerical values can be directly read through the dial indicator, and therefore the detecting device is suitable for application and popularization.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting the diameter of a cylinder and the inner diameter of a circular hole. Background technique [0002] The traditional detection method of large-diameter inner holes is manual direct detection with an inner diameter micrometer, and the displayed value on the inner diameter micrometer is the inner diameter tolerance value of the measured part; when the measured parts require high precision, it is difficult to measure or make errors with general-purpose measuring tools Larger, the above detection methods are both inefficient and difficult to guarantee quality. Because workers need to constantly adjust the detection position during inspection, it has always been difficult to inspect parts in large quantities. Contents of the invention [0003] The purpose of the present invention is to overcome the low efficiency of the currently used inner diameter micrometer f...
