[0002] During the production and processing of mechanical parts, in order to ensure the accuracy of the parts processing, the thickness of the workpiece needs to be detected. At present, the thickness of the workpiece is usually measured by clamping the two ends of the part with a fixed surface and a movable fixed surface, and then measuring the distance between the two fixed surfaces with a fixed scale to achieve the effect of part thickness measurement. However, this is often done by manual reading, and the error is large. Therefore, a Chinese patent with announcement number CN115773722A discloses a workpiece thickness detection device. The device uses laser detection to enable our products to perform thickness detection in real time, overcoming the disadvantage that the traditional part thickness detection device needs to read the scale during detection. The detection is more accurate and the detection error is greatly reduced.
[0003] However, the traditional detection method only uses a laser rangefinder. When the flatness of the contact surface between the workpiece and the load-bearing platform is low or the load-bearing surface is uneven, the error of the measured result will be amplified, resulting in reduced accuracy of the detection result.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-Figure 4 The utility model discloses a device for real-time detection of workpiece processing thickness, comprising a base 1, and also comprising a second distance measuring sensor 9, the second distance measuring sensor 9 is installed on the upper surface of the base 1, and the second distance measuring sensor 9 is used to measure the distance from the lower surface of the workpiece; a support frame 2, the support frame 2 is fixed on the base 1, and a moving plate 6 is installed on the support frame 2 along the vertical sliding, and a first distance measuring sensor 8 is installed on the moving plate 6, and the first distance measuring sensor 8 is used to measure the distance from the upper surface of the workpiece;
[0021] In this embodiment, when the distance between the first distance measuring sensor 8 and the second distance measuring sensor 9 is fixed, the first distance measuring sensor 8 is set to measure the distance from the upper surface of the workpiece to it, and the second distance measuring sensor 9 is used to measure the distance from the lower surface of the workpiece to it, and then the thickness detection at all positions of the workpiece can be achieved, and the detection result has low error and is more accurate.
[0022] In addition, in order to facilitate the movement of the workpiece between the first distance measuring sensor 8 and the second distance measuring sensor 9, the present embodiment also includes a moving component, which is arranged between the base 1 and the moving plate 6, and is used for the lateral movement of the workpiece to cross the gap between the first distance measuring sensor 8 and the second distance measuring sensor 9, thereby facilitating the vacancy of the upper and lower surfaces of the workpiece and preventing the flatness of the contact part between the workpiece and the workbench from affecting the detection results.
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the above-mentioned moving component includes a beam 10 fixed on the support frame 2, the beam 10 is located between the moving plate 6 and the base 1, and a first motor 13 is fixed at one end of the beam 10, a transverse screw rod 14 is installed at the output end of the first motor 13, a slider 11 is slidably installed in the beam 10, the slider 11 is threadedly connected to the transverse screw rod 14, and a bracket 12 is fixed at one end of the slider 11, and suction cups 15 are installed at equal intervals on one side of the bracket 12.
[0024] In this embodiment, one side of the workpiece is fixed by the suction cup 15, and the first motor 13 is started to rotate the transverse screw rod 14. The thread force generated by the threaded connection between the transverse screw rod 14 and the slider 11 causes the slider 11 to slide inside the crossbeam 10, and the bracket 12 further drives the workpiece to move, so that the workpiece can cross the gap between the first distance measuring sensor 8 and the second distance measuring sensor 9, so as to avoid unstable measurement results caused by manually holding the workpiece, and it is beneficial for the upper and lower surfaces of the workpiece to be vacated, so as to avoid the flatness of the contact part between the workpiece and the workbench affecting the detection results.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the device for real-time detection of workpiece processing thickness provided in this embodiment also includes an adjustment component, which is arranged in the support frame 2 and is used to adjust the distance from the movable plate 6 to the base 1 so as to cope with workpieces of different thicknesses.
[0026] Furthermore, the adjustment component includes a second motor 16 fixed inside the support frame 2, a longitudinal screw rod 5 is installed at the output end of the second motor 16, and one end of the movable plate 6 extends into the support frame 2 and is threadedly connected to the longitudinal screw rod 5.
[0027] In order to improve the stability of the movable plate 6 when it is lifted or lowered, a top plate 3 is fixed to the upper end of the support frame 2, a guide rod 4 is installed between the top plate 3 and the base 1, and sliding holes 7 adapted to the guide rod 4 are symmetrically opened on the movable plate 6.
[0028] In this embodiment, the second motor 16 is started to rotate the longitudinal screw rod 5, and the movable plate 6 is pulled through the sliding connection between the sliding hole 7 and the guide rod 4. The thread force generated by the threaded connection between the longitudinal screw rod 5 and the movable plate 6 causes the movable plate 6 to move on the support frame 2, thereby adjusting the distance from the movable plate 6 to the base 1, and further adjusting the distance between the first distance measuring sensor 8 and the second distance measuring sensor 9 to facilitate the use of workpieces of different thicknesses.
[0029] like Figure 1 and Figure 2 As shown, in order to facilitate the measurement of the workpiece thickness, the first ranging sensor 8 and the second ranging sensor 9 provided in this embodiment are both laser displacement sensors. In addition, a microprocessor electrically connected to the signal output ends of the first ranging sensor 8 and the second ranging sensor 9 is installed on the base 1. The microprocessor is used to analyze and process the ranging information of the first ranging sensor 8 and the second ranging sensor 9. Preferably, a display screen is also installed on the base 1. The display screen is electrically connected to the microprocessor for displaying the data processed and analyzed by the microprocessor, so that the staff can observe the thickness of the workpiece more intuitively.

[0031] The working principle and use process of the utility model are as follows: when in use, the second motor 16 is started to rotate the longitudinal screw rod 5, and the movable plate 6 is pulled through the sliding connection between the slide hole 7 and the guide rod 4. The thread force generated by the threaded connection between the longitudinal screw rod 5 and the movable plate 6 makes the movable plate 6 move on the support frame 2, thereby adjusting the distance between the movable plate 6 and the base 1, and further adjusting the distance between the first distance measuring sensor 8 and the second distance measuring sensor 9, so as to cope with workpieces of different thicknesses. One side of the workpiece is fixed by the suction cup 15, and the first motor 13 is started to rotate the transverse screw rod 14. The thread force generated by the threaded connection between the transverse screw rod 14 and the slider 11 , so that the slider 11 slides inside the crossbeam 10, and further the bracket 12 drives the workpiece to move, so that the workpiece can cross the gap between the first distance measuring sensor 8 and the second distance measuring sensor 9, so as to avoid the unstable measurement result caused by manually holding the workpiece, and it is beneficial to the upper and lower surfaces of the workpiece to be vacated, so as to avoid the flatness of the contact part between the workpiece and the workbench affecting the detection result. When the distance between the first distance measuring sensor 8 and the second distance measuring sensor 9 is fixed, the first distance measuring sensor 8 is set to measure the distance from the upper surface of the workpiece to it, and the second distance measuring sensor 9 is used to measure the distance from the lower surface of the workpiece to it, and then the thickness detection of the workpiece at all positions can be realized, and the detection result has low error and is more accurate.
