Abstract

The invention discloses a detection device for detecting the side clearance of a piston ring. The device comprises a sleeve. The inner diameter of the sleeve is consistent with the inner diameter of an air cylinder sleeve with a to-be-detected piston ring. Four detection windows are evenly arranged on the circumferential wall of the sleeve at equal intervals. The detection windows are used for feeler gauges to stretch into. Two feeler gauges are respectively used for penetrating through the detection windows to be inserted into the side clearance of the piston ring. By means of the detection device, whether the side clearance of the piston ring is qualified or not can be detected through judging whether the feeler gauges are matched with the side clearance of the piston ring or not. The detection device can rapidly and accurately detect whether the side clearance of the piston ring of an engine is qualified or not.

Description

technical field

[0001] The invention relates to the detection field of piston ring assembly characteristic items, in particular to a detection device for piston ring side clearance. Background technique

[0002] The side clearance of the piston ring refers to the gap between the end face of the piston ring and the piston ring groove after the piston is installed. The side clearance can prevent the piston ring from being stuck in the cylinder due to thermal expansion. If the side clearance of the piston ring does not meet the technical requirements, it is easy to cause engine blow-by, oil blow-by, stuck cylinder, easy wear of moving parts, abnormal consumption of lubricating oil, and seriously affect the power and reliability of the engine.

[0003] Strict engine development and test procedures need to arrange to test whether the side clearance of the piston ring meets the design requirements. For the detection method of the rectangular ring side clearance, the piston is plac...

Embodiment Construction

[0016] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0017] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0018] Such as Figure 1 to Figure 3 As shown, according to the detection device of the piston ring side clearance according to the specific embodiment of the present invention, the piston ring side clearance under the real assembly state of the piston ring can be detected with a feeler gauge. The detection device includes a sleeve 1 and two feeler gauges 4, and the sleeve The inner diameter 3 of 1 is consistent with the i...
