Technical Field

[0001] The utility model relates to the technical field of steel plate detection, in particular to a detection device for the thickness of a steel plate. Background Technique

[0002] The detection of the steel plate thickness is an important link to ensure the quality of the steel plate. Common methods include ultrasonic thickness measurement, which measures by using the ultrasonic reflection principle; electromagnetic induction thickness measurement, which is based on the electromagnetic induction principle. In addition, there is also ray thickness measurement, etc. During the detection, it is necessary to operate according to the specifications to ensure accurate data in order to judge whether the steel plate thickness meets the standards and usage requirements.

[0003] When detecting the thickness of a steel plate, it mainly relies on professional equipment for thickness detection. During the detection process, the operator needs to hold the detection probe and continuously move it on the steel plate for detection. This detection requires a person who masters professional operation techniques to carry out the detection, and there will be certain errors due to the operation techniques. Therefore, there is a lack of automated steel plate detection nowadays.

[0004] Based on this, a detection device for the thickness of a steel plate is proposed. Content of the Utility Model

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 3, the present utility model provides a technical solution:

[0023] A detection device for the thickness of a steel plate, comprising a base 1, a connecting frame 2 is connected to the upper end of the base 1, one end of the connecting frame 2 is connected to a sliding cylinder 3, a sliding bar 17 is slidably connected to the sliding cylinder 3, the structure of the sliding cylinder 3 is sleeved outside the sliding bar 17, through the limitation of the structure of the sliding cylinder 3, the sliding bar 17 can only move up and down in the vertical direction, a lifting block 5 is connected to the lower end of the sliding bar 17, a contact column 12 is slidably connected to the lifting block 5, there are two contact columns 12, and the two contact columns 12 are symmetrically arranged on the lifting block 5, the upper end of the contact column 12 is connected to a connecting plate 7, a upper spring 11 is connected between the connecting plate 7 and the lifting block 5, during detection, the upper spring 11 is in a stretched state, and a transmission mechanism for driving the sliding bar 17 to move up and down is connected to the connecting frame 2.

[0024] Specifically, as Figure 2 and Figure 3 shown, the transmission mechanism includes a motor 4, the motor 4 is fixedly connected to the connecting frame 2, the output end of the motor 4 is connected to a crank 15, one end of the crank 15 is rotatably connected to a swing bar 16, the swing bar 16 is rotatably connected to the sliding bar 17, during detection, the motor 4 rotates, when the rotation stops, the thickness data of the steel plate is recorded at this time, and each time during detection, the motor 4 cannot rotate a complete circle.

[0025] Specifically, as Figure 1 shown, a fixing frame 8 is connected to the upper end of the connecting plate 7, a scale bar 9 is connected to the fixing frame 8, the scale bar 9 is slidably connected to the lifting block 5, and the scale bar 9 is vertically arranged.

[0026] Specifically, as Figure 1 shown, a camera 10 is connected to the connecting frame 2, the camera 10 is arranged facing the scale bar 9, and the camera 10 can record the data on the scale bar 9 in a stationary state.

[0027] Specifically, as Figure 2 and Figure 3 shown, a pressing block 6 is slidably connected to the lower end of the lifting block 5, a hole that fits the contact column 12 is opened on the pressing block 6, and the lower end of the contact column 12 can pass through the hole and abut against the surface of the steel plate. Since the steel plate is squeezed by the pressing block 6, the steel plate is in a flat state.

[0028] Specifically, as Figure 2 and Figure 3 shown, a telescopic rod 13 is connected to the upper end of the pressing block 6, a lower spring 14 is sleeved outside the telescopic rod 13, and the upper and lower ends of the lower spring 14 are respectively connected to the lifting block 5 and the pressing block 6. By setting the lower spring 14, the movement of the lifting block 5 can drive the pressing block 6 to move synchronously.

[0029] In summary, for a steel plate thickness detection device provided by this embodiment, when it is necessary to detect the thickness of a steel plate, the steel plate can be placed above the base 1, and at the same time, the motor 4 is started. The motor 4 drives the crank 15 to rotate, and the crank 15 drives the slide bar 17 to move up and down in the sliding cylinder 3;

[0030] When the height of the lifting block 5 decreases, at this time, the contact column 12 and the pressing block 6 will contact the base 1. The pressing block 6 can be used to press the steel plate to be measured, so that the steel plate is in a flat state, improving the thickness detection accuracy. As the lifting block 5 continues to move down until it contacts the pressing block 6, at this time, the lifting block 5 cannot move further, and the motor 4 stops rotating. The camera 10 connected to the connecting frame 2 is relied on to record the value on the scale bar 9 in a static state, so as to understand the thickness of the steel plate. There are two camera 10 structures, and the surface condition of the steel plate can be understood by comparing the data differences. When the data difference is large, it means that the surface of the steel plate is uneven. When the data difference is small, the average value of the two groups of data can be taken as the detected thickness of the steel plate. Through this setting, the thickness detection of the steel plate can be automatically completed, the detection steps are unified, and the error is reduced.

[0031] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
