Flaw inspection system for spring gasket and inspection method

Abstract

The invention relates to a flaw inspection system for a spring gasket, which comprises a system bracket (2) connected with a fixed part (1), wherein the system bracket (2) is provided with two bracket walls (3) a certain distance away from each other; and the spring gasket (6) is fixed on the bracket walls (3) of the system bracket by mounting parts (4). The flaw inspection system further comprises proximity sensors (7) arranged in pairs at corresponding positions on the two bracket walls (3) of the system bracket. The invention also discloses an inspection method adopted by the flaw inspection system. In the flaw inspection system and the inspection method for the spring gasket, the conditions, such as missing, reverse mounting, excessive mounting and the like, of the spring gasket can be quickly and accurately inspected; and the system and the method have lower cost and are convenient to use.

Description

technical field [0001] The invention relates to a detection device and a detection method thereof, in particular to a spring washer defect detection system and a detection method thereof. Background technique [0002] Gasket is a mechanical seal between two objects, usually to prevent pressure leakage between two objects. Since machined surfaces can never be perfect, irregularities can be filled with shims. Gaskets are usually made of sheet materials such as paper pads, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymers such as polyvinyl chloride. Gaskets for certain applications may contain asbestos. [0003] A spacer is a hole (usually in the middle) of a thin plate (usually round) that is usually used to distribute the load-threaded fasteners. Other uses are as spacers, springs (Belleville gaskets, wave gaskets), wear pads, pre-display devices, lock devices. Rubber gaskets are also used in faucets (valve) to cut off t...

AI Technical Summary

Problems solved by technology

[0004] At present, due to the relatively large deformation of the sheet-shaped elastic gasket itself, the zero-defect detection control measures or detection methods for the sheet-shaped elastic gasket are very simple. Generally, visual inspection is used, and the sensor detects whether it is missing or over-installed. Such a detection or control method will bring certain risks to the product itself and process control, and the RPN value of the corresponding failure analysis is also very high; and if the image detection system is used, it is particularly expensive

Therefore, simple and effective control measures need to be improved
