[0003] In the above-mentioned parts shape detection device, the columnar parts (such as steel) are placed in two oppositely arranged V-shaped grooves of the part placement rack during detection, but when parts with different diameters are placed on the V-shaped grooves, due to the different diameters, , will cause the distance from the outer surface of the part to the displacement sensor to be different, and the high-precision displacement sensor has higher requirements for the measurement distance. If the distance from the outer surface of the part to the displacement sensor is not within the precise range, the measurement data will be inaccurate

The invention proposes a measurement distance self-adaptive type measuring system and a control method for steel external dimension parameters. The measurement system includes two brackets for placing the steel to be tested, a distance sensor for detecting its external dimension parameters is arranged directly under the steel to be tested, each of the brackets includes a base and a support fixed on the base, and the support The top of the seat is hinged with splint 1 and splint 2. The splint 1 and splint 2 are arranged oppositely and a V-shaped groove with an upward opening is formed between them. The stand has two driving structures that move in opposite directions or in opposite directions, the driving structure is connected with a control unit, and the control unit controls the driving structure to work. The measurement system can accurately adjust the distance from the outer surface of the steel to be measured to the distance sensor within the precise range of the distance sensor, so that the data collected by the subsequent distance sensor is more accurate.
Description
technical field [0001] The invention relates to the field of steel shape parameter detection, in particular to a measuring distance self-adaptive steel shape parameter measurement system and a control method. Background technique [0002] In the process of parts processing and production, detecting the shape of parts is a necessary means to judge whether the processing of parts to be tested is qualified. For example, a Chinese patent discloses a part shape detection device [the authorized announcement number is CN209131599U], which includes a part placement frame for placing the parts to be tested; the testing mechanism includes at least one displacement sensor and at least one distance sensor, and the displacement sensor is used to scan the parts to be tested. The external dimension parameters of the part, the distance sensor is used to detect the displacement of the displacement sensor moving along the direction perpendicular to the section of the part to be tested after s...
