Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sensor size detection, in particular to a size detector for processing a liquid level sensor. Background Art
[0002] A liquid level sensor is a pressure sensor that measures liquid level. A static pressure submersible level transmitter works based on the principle that the static pressure of the measured liquid is proportional to the liquid's height. It uses an isolated diffused silicon sensor or a ceramic capacitor pressure sensor to convert the static pressure into an electrical signal. This signal is then converted to a standard electrical signal after temperature compensation and linear correction. It is suitable for measuring the liquid level of various media in systems and industries such as petrochemicals, metallurgy, electricity, pharmaceuticals, water supply and drainage, and environmental protection.
[0003] During the production process of liquid level sensors, the sensor end is a metal tubular structure. Generally, electronic detection components and seals need to be installed in the metal tube. Since the size of electronic components is fixed, the actual production size of the metal tube needs to meet the installation requirements of the electronic components. Therefore, the inner diameter of the metal tube needs to be tested during the production process. Only metal tubes that meet the size standards can be put into use. Traditional size detection devices cannot detect the inner diameter of the metal tube more comprehensively and accurately. At the same time, qualified and unqualified products cannot be screened during the detection process, and manual selection is required, resulting in low detection efficiency. Summary of the Invention

[0008] The pneumatic assembly includes an air cylinder fixedly arranged on one side of the carrying arm, a connecting pipe fixedly connected between the air cylinders, a telescopic tube fixedly connected to one side of the connecting pipe, one end of the telescopic tube fixedly connected to the fixed plate and connected to the inside of the rotating cylinder, a push column slidably arranged at one end of the air cylinder, and one side of the push column is arranged corresponding to the valve rod.
[0009] As a preferred technical solution of the present invention, the clamping assembly includes a piston block slidably arranged at the end of the air transmission tube, one side of the piston block is fixedly connected to the guide column, one end of the guide column passes through the air transmission tube, and the end is fixedly connected to the clamping block, and an elastic member is sleeved on the guide column.

At the same time, under the action of the installation motor, the driving gear drives the rotating cylinder to rotate through the transmission gear, thereby driving the detection head on the side wall of the installation rod to rotate around the inner wall of the metal tube and move horizontally at the same time to achieve comprehensive detection. If the inner wall of the metal tube is sunken or convex during the detection process, it means that it does not meet the requirements. If it meets the standard size, when the detection head moves to the inward or outward convex part, the stop rod will move under the action of the reset part, and the air vent will move into the air pipe. Under the action of the pressure accumulator pump, the air pipe will send the gas into the pressure accumulator through the telescopic tube, which will drive the push column to push the valve stem to move. The valve mouth on the valve stem moves out of the air transmission tube, and the piston block loses the air pressure support. It is reset under the action of the elastic part, and the clamping block is separated from the metal tube, and the metal tube falls, indicating that the size is unqualified. Otherwise, it means that the size of the metal tube is qualified. Then, under the action of the incomplete gear and the linkage gear, the mounting plate is driven to rotate intermittently to feed the material, thereby realizing continuous detection. The above process realizes efficient and accurate detection of metal tubes, comprehensive detection, and at the same time realizes the screening of qualified and unqualified metal tubes. It is flexible and convenient to operate and use, and the work efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS
