Description

Technical Field

[0001] The present invention relates to the field of detection, and particularly to a microcrystalline glass strength detection device. Background Art

[0002] Microcrystalline glass is a composite glass and a newly developed new building material. Like ceramics, microcrystalline glass is composed of crystals. Microcrystalline glass has higher brightness than ceramics and stronger toughness than glass. After the production of microcrystalline glass is completed, it is necessary to detect the strength of the microcrystalline glass so that the produced microcrystalline glass can be quickly put into use.

[0003] After retrieval, a Chinese patent application with the publication number of CN119935771A discloses a microcrystalline glass panel anti-mechanical impact performance test system, which includes a base body, an impact head, a connecting piece, an elastic member and a first piston. The base body is provided with a medium cavity, an impact cavity and a storage cavity. The impact cavity communicates with the medium cavity and penetrates to the surface of the base body. The medium cavity and the impact cavity are both spaced from the storage cavity. The first piston is slidably fitted in the medium cavity. The connecting piece is slidably fitted in the impact cavity. The side wall of the impact cavity is provided with a first flow channel and a second flow channel. The first flow channel communicates with the medium cavity, and the second flow channel communicates with the storage cavity. The connecting piece is provided with a connecting flow channel. The medium cavity is used to accommodate a liquid medium. The elastic member abuts between the first piston and the connecting piece. The impact head is installed at one end of the connecting piece away from the medium cavity. It can more accurately simulate the situation of the mechanical impact received by the microcrystalline glass panel during actual use and can accurately screen the microcrystalline glass panel suitable for induction cooker products.

[0004] When the existing equipment detects the strength of microcrystalline glass, it usually squeezes the surface of the microcrystalline glass through a detection mechanism, and the squeezing method is usually surface contact or point contact. Therefore, the detection method is relatively single, and the detection result often has limited detection data due to the single detection method, thus affecting the detection effect of microcrystalline glass.

[0013] The beneficial effects of the present invention are as follows: 1. By means of the provided moving component and detection component, when detecting the strength of the glass-ceramics, place the glass-ceramics on the clamping mechanism, start the clamping mechanism, and perform clamping and fixing on the glass-ceramics through the clamping mechanism. After the fixing is completed, start the hydraulic rod, and the hydraulic rod will drive the detection component to move downward. When the bottom of the detection pressing plate contacts the top of the glass-ceramics, at this time, the contact mode between the detection pressing plate and the glass-ceramics is surface contact. The detection pressing plate will drive the push plate to move upward under the action of pressure, and when the push plate moves upward, it will drive the third rack to move synchronously. When the third rack moves, it will drive the third gear to rotate through meshing, and while the third gear rotates, it will make the fourth rack move downward through meshing. When the fourth rack moves downward, it will drive the detection head to move downward synchronously. At this time, when the detection head moves downward, it will act on the surface of the glass-ceramics. At this time, the detection mode between the detection head and the glass-ceramics is point contact. Thus, through the cooperation between the detection pressing plate and the detection head, the strength of the glass-ceramics can be effectively detected. By the combined action of surface contact and point contact on the surface of the glass-ceramics, the diversity of the glass-ceramics strength detection can be improved. During this period, the moving component drives the detection component to move, so as to facilitate the detection of other parts of the glass-ceramics, preventing the detection data from being limited due to the single detection method, thus affecting the detection effect of the glass-ceramics; 2. By means of the provided clamping mechanism and reinforcement mechanism, when the clamping mechanism clamps and fixes the glass-ceramics, as the clamping mechanism clamps the glass-ceramics, at this time, the clamping plate will move to one side of the fixed clamp under the pressure of the glass-ceramics. At this time, the first rack will move synchronously, and when the first rack moves, it will mesh with the first gear. The first gear drives the rotating rod to rotate under the meshing action of the first rack, and the second gear will rotate synchronously with the rotation of the rotating rod. At this time, when the second gear rotates, it will mesh with the second rack, and the second rack will drive the push rod to move downward under the meshing action of the second gear. When the push rod moves downward, it will push the reinforcement plate to move downward. At this time, the reinforcement plate will act on the top of the glass-ceramics. Through the cooperation between the clamping mechanism and the reinforcement mechanism, the stability of the glass-ceramics detection can be effectively improved, thereby improving the detection effect of the glass-ceramics, and preventing the glass-ceramics from slipping during the detection process due to poor stability, thus affecting the detection of the glass-ceramics.
