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
The present invention relates to a kind of pick-up unit and detection method thereof, is a kind of defect detecting system and detection method thereof of spring shim specifically.
Background technology
Pad (gasket) is two mechanical seals between the object, usually with the leakage that is under pressure between two objects that prevent.Because machining surface can not be perfect, use pad can fill up scrambling.Pad is processed by flaky material usually, like packing paper, and rubber, silicon rubber, metal, cork, felt, neoprene, nitrile rubber, spun glass or plastic polymer (like polychlorodifluoroethylene).The pad of application-specific possibly contain asbestos.
Pad is that a leak (usually in the centre) of thin plate (round usually) normally is used to the load thread securing member that distributes.Other purposes are as the interval, spring (Belleville pad, ripple pad), wear-resistant pad, preparatory display device, locking device.Rubber washer also is used in water swivel (valve) to cut off flowing liquid or gas.Rubber or silicon spacer also can use, to reduce the vibration of fan.Usually the pad external diameter is about the twice of internal diameter.
At present; Because the bigger factor of deflection of thin slice shape elastomeric pad self is very single to the zero-fault detection control measure or the detection means of thin slice shape elastomeric pad, generally all adopts range estimation; Whether neglected loading of sensor; Whether adorn, such detection or control method more, the RPN numerical value of corresponding failure analysis is also very high to product self and process control if all will bring certain risk; And if adopt the special costliness of image-type detection system.So simple and effective control measure have much room for improvement.
Summary of the invention
The technical matters that the present invention will solve is: a kind of defect detecting system and detection method thereof of spring shim are provided, and it can detect the neglected loading of spring shim quickly and accurately, instead adorn or many dresses situation.
In order to solve the problems of the technologies described above; The present invention provides a kind of defect detecting system of spring shim; Comprise the system frame that links to each other with fixed part; Said system frame has two cradle walls separated by a distance, and spring shim is fixed on through installing component on the cradle wall of said system frame, and said defect detecting system also comprises the proximity transducer of mounted in pairs correspondence position on two cradle walls of said system frame.
According to defect detecting system of the present invention, be preferably said defect detecting system and comprise two pairs of proximity transducers that are installed in correspondence position on said two cradle walls, two proximity transducers are installed on each cradle wall.
According to defect detecting system of the present invention, be preferably said proximity transducer and be installed on the sensor mounting blocks, said sensor mounting blocks is provided with the sensor mounting hole.
According to defect detecting system of the present invention, being preferably installing component is clamping screw, and said fixed part is a fixed head.
A kind of defect inspection method of spring shim, it may further comprise the steps:
1), position the defect detecting system of spring shim fixing through fixed part;
2), through proximity transducer, detect the distance between every pair of sensor;
3), according to the distance between detected every pair of sensor, judge whether neglected loading of spring shim, anti-dress or many dresses.
According to defect inspection method of the present invention, be preferably before said step 1), also comprise detection and localization to installing component.
According to defect inspection method of the present invention, be preferably in said step 3), when detecting spring shim neglected loading, anti-dress or when adorning more, corresponding neglected loading, anti-dress or adorn signal lamp more and do not work.
The defect detecting system of spring shim of the present invention and detection method thereof, it can detect the neglected loading of spring shim, anti-situation such as dress or many dresses quickly and accurately, and cost tells somebody what one's real intentions are, easy to use.
