Description

Technical Field

[0001] The utility model relates to the field of measuring devices, in particular to a device for detecting the thickness of metal plates, and is particularly suitable for measuring the thickness of large-sized steel plates. Background Art

[0002] In modern heavy industrial production, from the feeding to the cutting of steel plates, intelligent traveling cranes or truss manipulators have gradually been used for automatic loading and unloading and cutting of steel plates, realizing a fully automatic operation mode. The entire production line runs fully automatically without manual intervention. When grasping thin steel plates, due to the presence of oil films on the steel plate surfaces, the steel plates will firmly adsorb to each other, resulting in the possibility of simultaneously lifting multiple stacked steel plates during the grasping process. During transportation, the steel plates may fall, easily causing safety accidents and posing huge safety hazards. At the same time, due to the use of robotic hands for automatic operation, multiple stacked steel plates are likely to be adsorbed together and placed on the cutting machine for cutting, which may damage the cutting machine and affect the overall cutting quality.

[0003] In the prior art, the thickness of metal plates is often measured by using measuring rulers or vernier calipers. This method requires manual operation and has a low measurement efficiency. When measuring the thickness of metal plates by using a mechanical structure, the method relies on limiting both sides of the plate and then measuring the thickness of the plate along the edge of the plate through instruments such as rangefinders.

[0004] The above technical methods require placing the metal plate on the detection table and fixing the plate by relying on limiting or clamping structures. The efficiency of continuously measuring metal plates is low, and it is difficult to measure large-area whole steel plates, especially during the loading and handling operations on the production line.

[0005] In view of this, there is an urgent need for a tool for measuring the thickness of plates, which has a simple structure and is easy to install. It can timely detect the thickness of plates during the continuous production line loading and cutting operation process, can achieve automatic and rapid detection, while improving the overall cutting quality, can effectively eliminate the safety hazards of the plates during the processing process, and improve the overall efficiency of plate processing.

[0022] As described in the background art, existing tools for measuring the thickness of metal sheets need to place the metal sheet on the detection table and rely on a limiting or clamping structure to fix the sheet. The efficiency of continuously measuring metal sheets is relatively low, and it is difficult to measure a large-area whole steel plate, and it is impossible to achieve modern assembly-line type automated operations. In view of this, the present utility model patent proposes a tool for measuring the thickness of metal sheets that can solve the above problems.

[0023] As Figures 1 to 3As shown, a sheet thickness measurement tool shown according to some exemplary embodiments is used for measuring the thickness of a sheet 100, and includes a driving part 10 that is telescopically fixed on a mounting base 200, and a detection part 20 that is releasably clamped to the sheet 100. The detection part 20 is arranged at one end of the driving part 10 away from the mounting base 200 and extends in the telescopic direction of the driving part 10. Among them, the detection part 20 includes a first clamping plate 22, a second clamping plate 23, a rotary cylinder 24 and a sensor 25 that are connected to the driving part 10 through a fixing plate 21. The first clamping plate 22 is fixed on the fixing plate 21 and is on the same side as the driving part 10; the second clamping plate 23 is arranged on the opposite side of the fixing plate 21 and is fixed to the moving end of the rotary cylinder 24; the rotary cylinder 24 and the sensor 25 are arranged in a linked manner, are telescopically arranged with the fixing plate 21, and extend in the direction away from the fixing plate 21. Thus, under the action of the driving part 10, the detection part 20 can realize the adjustment of different positions, so as to be applicable to the detection of sheets at different positions. Through the drive of the rotary cylinder 24, the relative position between the second clamping plate 23 and the first clamping plate 22 can be conveniently adjusted, so as to quickly and conveniently clamp the sheet, so as to be able to floatingly measure the thickness of the steel plate; through the mounting base 200, the installation of the entire sheet thickness measurement tool can be quickly and conveniently realized, the structure is simple and the installation is convenient, and during the operation process of continuous in-line feeding and cutting, the thickness of the sheet can be detected in a timely manner, and automatic rapid detection can be realized. While improving the overall quality of cutting, it can effectively eliminate potential safety hazards during the processing of the sheet and improve the overall efficiency of sheet processing.

[0024] In a preferred embodiment of the present application, as Figure 1 shown, in order to realize the thickness detection of sheets with different thicknesses, the rotary cylinder 24 is a rotary clamping cylinder. Thus, under the drive of the rotary clamping cylinder, the relative position between the second clamping plate 23 and the first clamping plate 22 can be adjusted, including changes in the measurable stroke, clamping position and shape, which can adapt to the measurement of different steel plate shapes, such as the case of steel plate bending deformation, and improve the flexibility of the application scenario of the entire measurement tool. Preferably, the second clamping plate 23 and the first clamping plate 22 are misaligned and arranged perpendicularly.

[0025] Preferably, in order to improve the measurement accuracy, the sensor 25 is a displacement sensor. Preferably, the sensor 25 is arranged parallel to the rotary cylinder 24. The fixed ends of the sensor 25 and the rotary cylinder 24 are fixed to the fixing plate 21, and the telescopic ends of the sensor 25 and the rotary cylinder 24 extend in the direction away from the fixing plate 21. In this preferred embodiment, the telescopic ends of the sensor 25 and the rotary cylinder 24 extend downward.

[0026] Optionally, to further improve the stability and reliability during the measurement process, a linkage plate 26 fixed to the telescopic ends of the sensor 25 and the rotary cylinder 24 is further included. Further, the linkage plate 26 is disposed at the farthest end of the telescopic ends of the sensor 25 and the rotary cylinder 24. Thus, the sensitivity during the measurement process can be improved, and then the thickness measurement of the floating sheet material can be realized.

[0027] In summary, the detection unit provided by the present utility model can realize the thickness detection of sheets with different thicknesses, can adapt to the measurement of different steel plate forms, has a wide application scenario, high flexibility in use, low positioning requirements for the sheet material, can realize the floating measurement of the steel plate thickness, and can adapt to the measurement of different steel plate forms, such as the case where the steel plate is bent and deformed.

[0028] In the preferred embodiment of the present application, as Figure 2 shown, the driving unit 10 includes a telescopic cylinder 11 and a connecting block 12. The fixed end of the telescopic cylinder 11 is fixed to the mounting seat 200, and the telescopic end of the telescopic cylinder 11 is slidably connected to the detection unit 20 through the connecting block 12. Optionally, the driving unit 10 further includes a linear guide rail 13 fixed to the detection unit 20 and slidably connected to the connecting block 12, and the linear guide rail 13 extends along the vertical direction. Specifically, in this preferred embodiment, the linear guide rail 13 is disposed on the fixing plate 21 and extends along the vertical direction.

[0029] The working principle of the present application: This sheet thickness measuring tool is fixed at the position of the sheet 100 to be detected through the mounting seat 200. In the initial state, the second clamping plate 23 is misaligned with the first clamping plate 22 and is vertically arranged. At this time, the second clamping plate 23 and the linkage plate 26 are in a parallel state. When the thickness of the sheet needs to be measured, for example, when the sheet blanking picking tool automatically picks up the sheet to the cutting and loading and cutting station, and the thickness of the sheet needs to be measured. The telescopic cylinder 11 extends, and after driving the first clamping plate 22 to contact the upper surface of the sheet 100, at this time, due to the linear guide rail 13 disposed between the connecting block 12 and the fixing plate 21, the connecting block 12 can slide relative to the fixing plate 21. At this time, the first clamping plate 22 is blocked after contacting the sheet 100 and will not generate a downward pressure on the sheet 100 to affect the surface of the sheet 100. When the telescopic cylinder 11 is fully extended, the rotary cylinder 24 rotates, driving the second clamping plate 23 to rotate to a position parallel to the first clamping plate 22, and then the telescopic end of the rotary cylinder 24 retracts, driving the second clamping plate 23 to move upward until it contacts the lower surface of the sheet 100. At this time, the position of the telescopic end of the sensor 25 linked with the rotary cylinder 24 also changes accordingly. Through the numerical changes before and after, the thickness of the sheet 100 is finally obtained.

[0030] The sheet thickness measuring tool provided by the above embodiment of the present application has at least the following characteristics:

[0031] The plate thickness measuring tool provided in the embodiments of the present application can achieve the thickness detection of plates with different thicknesses, can adapt to the measurement of different steel plate forms, has a wide application scenario and high flexibility in use, has low requirements for the positioning of the plate, can achieve the floating measurement of the steel plate thickness, and can adapt to the measurement of different steel plate forms, such as the case of steel plate bending deformation; under the action of the driving part, the detection part can achieve the adjustment of different positions, so as to adapt to the detection of plates at different positions.
