Description

Technical Field

[0001] The utility model relates to the technical field of aperture detection, in particular to an aperture detection device. Background Art

[0002] The connecting rod is an important part in the engine. It connects the piston and the crankshaft. Its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft, and transmit the force acting on the piston to the crankshaft to output power. The detection of the connecting rod includes the detection of the aperture of the big end end of the connecting rod and the aperture detection of the elliptical hole at the small end end of the connecting rod. For example, the Chinese patent with the existing authorization announcement number CN219798289U discloses an engine connecting rod big end hole diameter detection device, which includes a detection platform, a support frame and a control panel. The support frame is installed at the upper end of the detection platform, and the control panel is installed at the upper end of the support frame. It also includes: a detection mechanism for automatically detecting the aperture of the big end hole of the engine connecting rod at multiple angles, and the detection mechanism is installed on the support frame. The beneficial effect of the utility model is: by inserting two detection rods into the inner side of the aperture of the big end hole of the engine connecting rod and tightly fitting it, and detecting the distance between the two detection rods by the distance sensor on the detection rod, the aperture of the big end hole of the engine connecting rod is detected, and the two detection rods meet the detection of the big end hole aperture of engine connecting rods of different models. At the same time, the detection rod rotates automatically, and can automatically detect multiple times from different directions, thereby improving the detection stability and detection accuracy of the aperture of the big end hole of the engine connecting rod.

[0003] However, in actual application, the above-mentioned equipment still has the following shortcomings: when the above-mentioned equipment is used for aperture detection of the elliptical hole at the small end of the connecting rod, it is necessary to first measure the major axis length of the elliptical hole, and then re-measure the minor axis length of the elliptical hole. It takes two measurements to obtain the aperture of the elliptical hole. The measurement process is relatively time-consuming, resulting in low aperture detection efficiency of the elliptical hole at the small end of the engine connecting rod. Utility Model Content
