Description

Technical Field

[0001] The utility model relates to the technical field of thickness gauges, in particular to a steel plate thickness gauge. Background Art

[0002] Thickness gauges are often used in industrial production to continuously or sample the thickness of products (such as steel plates, steel strips, films, paper, metal foils and other materials). In the prior art, when measuring the thickness of steel plates, some use manual measurement tools to measure the thickness of the steel plates. However, in the existing thickness gauge equipment, the laser test head is fixed and cannot be effectively adjusted to the optimal position during the test, resulting in inaccurate testing. Secondly, the travel distance of the steel plate cannot be detected during the test, so the thickness data of different test points of the steel plate cannot be recorded, resulting in inaccurate test data.

[0003] Therefore, further improvement is needed. Utility Model Content

[0004] Aiming at the problems existing in the prior art, the utility model provides a steel plate thickness measuring machine.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] The utility model provides a steel plate thickness measuring machine, comprising:

[0007] A conveying mechanism, comprising a conveyor belt, wherein the conveyor belt is used to convey the steel plate;

[0008] A stroke detection device, arranged on one side of the conveyor belt, and used for detecting the moving distance of the steel plate conveyed by the conveyor belt;

[0020] The steel plate is transported to the inspection group through the conveying mechanism for thickness inspection. Multiple laser test heads measure the thickness of the steel plate at the same time. Multiple sets of data can be measured at one time, which improves the measurement accuracy and work efficiency.

[0021] At the same time, the travel encoder is used in conjunction with the detection group for detection. Whenever the travel encoder reaches a certain position, the laser test head starts to measure the thickness. It can measure multiple sets of data and thickness data of multiple points of the steel plate, and then effectively record the thickness data of different test points of the steel plate. The qualified data is verified by the measured multiple sets of data.
