Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] like Figure 1 to Figure 3 As shown, the bottom of the device is surrounded by aluminum profiles to form a rectangular base, and four aluminum profiles are erected in the middle, two parallel, with different heights, used as support rods for the mallet and electromagnet, and all profiles are connected and fixed by corner fittings. Fix the adsorption sheet on one side of the mallet through countersunk bolts, connect the mallet to the drive shaft through a connector, and insert the pinion into one end of the drive shaft. Both ends of the shaft are connected to the aluminum support frame through bearings and bearing seats, and on a horizontal plane, 1 / 4 and 3 / 4 of the...

Abstract

The invention discloses a ceramic body defect detection device and method based on acoustics. The device comprises a base, a support, a mallet (with a ferromagnetic adsorption sheet), an electromagnet, a motor, a computer system and the like. Before electrification, a ceramic body to be detected is placed on the plane where the base is located, the electromagnet is fixed to the support with the adjustable height, and the mallet can freely and repeatedly swing; after electrification, the stepping motor pulls the mallet to rise to a specific height, and one surface of the mallet adsorption sheetis in contact with the electromagnet and is adsorbed; after a power failure, the mallet falls down to knock the ceramic body, and a microphone collects a knocking sound signal. Furthermore, the system forms a fixed-height and timing control and sound wave collection and detection device for knocking porcelain, solves the problems that a nondestructive detection device for ceramic body structure defects is high in cost and knocking sound signals cannot be collected regularly and quantitatively for digital analysis, reduces the experience dependence on operators, and has the advantages of beingsimple to operate and high in objective consistency of detection results.

Description

technical field [0001] The invention relates to a detection device and method for ceramic body defects, in particular to an acoustic-based ceramic body defect detection device and method, belonging to the field of ceramic production. Background technique [0002] Ceramic products are closely related to the daily life of human beings. Due to the complex manufacturing process and various procedures, even under the same process conditions, the strength of the products varies greatly. The quality inspection of finished products is an important part of its production. The highly reliable non-destructive finished product testing method and device can effectively improve the production efficiency and economic benefits of ceramic products. [0003] At present, there are many methods for non-destructive testing of ceramic products, such as radiographic testing, ultrasonic testing, etc., but most of these methods are expensive and complicated to operate; ceramic defect detection based...
