Background technique

After the workpiece is produced, it is generally necessary to measure each part of the workpiece. The bottom thickness is a parameter value that needs to be measured after the aluminum can is formed. Thickness gauges are generally used as more precise instruments for wall thickness testing of metal parts. Thickness gauges use ultrasonic principles to measure thickness, which requires a good testing environment and is limited to metal thickness measurement. Due to different metal materials, it is necessary to adjust the sound velocity and use samples repeatedly. Block calibration can ensure the accuracy of measurement, and the roughness of the metal surface will also affect its accuracy. At the same time, thickness measurement is only limited to metal thickness measurement, the scope of application is limited, and the cost is relatively high, so it is not widely accepted by people.

Preferably, the guide rails are two polished rods parallel to each other, through holes parallel to each other are arranged on the sliding plate, and the polished rods are inserted into the through holes. In order to improve the accuracy of measurement, the matching structure of the polished rod and the through hole is used, the structure is simple, and the stability is good.

As preferably, the ejector rod is located at the center of the sliding plate, and the ejector rod includes two parts, the lower part of the ejector rod is a cylinder, the upper part of the ejector rod is a cone, the top of the cone is a spherical surface, and the outer diameter of the ejector rod is not larger than the tank to be tested. inner diameter of the body. The lower part of the ejector rod is a cylinder, which is convenient for fixing the ejector rod on the sliding plate, and has a good supporting effect on the tank body. The upper part of the ejector rod is a cone, which is convenient for inserting the tank body into the ejector rod. The end of the ejector rod is a spherical surface, which can ensure the point contact measurement when measuring the bottom of the tank body, and improve the measurement accuracy. The diameter of the ejector rod is almost the same as that of the tank body, which can facilitate the support and positioning of the tank body, thereby facilitating measurement.

Preferably, the bracket is a rectangular bracket, the bracket includes a side bracket vertically fixed on the base, the side bracket is connected with a horizontal bracket that can move up and down along the side bracket, and the dial indicator is fixed on the horizontal bracket. The bracket includes brackets in two directions, horizontal and vertical, and can be adjusted in the horizontal and vertical directions to meet the adjustment of the position of the bracket in different positions.

Therefore, the bottom thickness measuring device of a kind of tank body of the utility model has the following advantages: the position of the tank body to be tested is adjusted by using the movement of the sliding plate on the guide rail, the adjustment is flexible and convenient, and the structure is simple; The diameter of the body is almost the same, which can facilitate the positioning of the tank body and realize the stable support for the tank body; the end of the ejector rod is in point contact with the tank body to be tested, and the thimble of the dial gauge is also in point contact with the tank body to be tested, thereby improving The accuracy of the measurement point.
