[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0020] This example discloses a multi-point detection device for honeycomb ceramics. See [link to relevant documentation]. Figures 1 to 5 The device includes a first diameter gauge 1 and a second diameter gauge 2. The first diameter gauge 1 is fixedly installed at the bottom of the workbench 3 to measure the parameters of the bottom position of the workpiece to be measured. The second diameter gauge 2 is installed above the first diameter gauge 1 in a lifting manner to measure the parameters at different heights of the workpiece to be measured. The first diameter gauge 1 and the second diameter gauge 2 have the same structure and both include a transmitter 4 and a receiver 5 set on both sides of the workpiece to be measured. The transmitter 4 includes a laser 6. A multifaceted mirror 7 is set in the laser emission direction of the laser 6. A motor 8 is installed at the bottom of the multifaceted mirror 7 to drive the multifaceted mirror 7 to rotate. A reflector 9 is set on one side of the multifaceted mirror 7 and a lens 10 is set on the other side to output parallel light.

[0021] A turntable 11 is installed on the workbench 3 between the transmitter 4 and the receiver 5 to support the workpiece to be tested.

[0022] The second diameter measuring instrument is installed on the lifting assembly 12, which includes a first motor 14. The power shaft of the first motor 14 is connected to a lead screw 15, and a nut 16 is threaded onto the lead screw 15. The nut 16 is installed on the second diameter measuring instrument 2 via a connecting plate 17.

[0023] The lifting assembly 12 is mounted on the lateral moving assembly 18 via the back plate 13. The lateral moving assembly 18 includes a second motor 19. The drive shaft of the second motor 19 is equipped with a drive wheel 20. The drive wheel 20 is connected to the driven wheel 22 via a transmission belt 21. The back plate 13 is fixed on the transmission belt 21 via upper and lower clamping plates 23.

[0024] A first guide rail 24 is installed on one side of the back plate 13, and a first slider 25 that can slide on the first guide rail 24 is installed on the connecting plate 17 to achieve stable movement of the gripper; a second slider 26 is installed on the other side of the back plate 13, and a second guide rail 27 is installed on the transverse moving component 18 to achieve stable movement of the longitudinal moving component on the transverse moving component.

[0025] During operation, the honeycomb ceramic workpiece to be measured is placed on the turntable 11 on the workbench, ensuring it is within the measurement range of the diameter gauge. The laser 6 in the transmitter 4 emits a laser beam. The motor 8 drives the polygon mirror 7 to rotate, causing the laser beam to form multiple beam directions under the reflection of the polygon mirror 7. After reflection by the polygon mirror 7, the laser beam direction is further adjusted by the reflector 9, and then focused by the lens 10 to form a parallel beam for measuring the size and shape of the workpiece. The first diameter gauge 1 is fixed to the bottom of the workbench 3 to measure the parameters of the bottom position of the workpiece. The second diameter gauge 2 is mounted on the lifting assembly 12. The first motor 14 drives the lead screw 15 to rotate, causing the nut 16 to move up and down along the lead screw 15, thereby adjusting the height of the second diameter gauge 2 to measure parameters at different heights of the workpiece. The second motor 19 in the lateral movement assembly 18 drives the drive wheel 20 to rotate, which in turn drives the driven wheel 22 via the transmission belt 21, causing the back plate 13 to move laterally, adjusting the lateral position of the diameter gauge. The second slider 26 on the back plate 13 slides on the second guide rail 27 on the transverse moving assembly 28, realizing the longitudinal movement of the diameter gauge and ensuring that the diameter gauge can cover all measurement points of the workpiece. The receiver 5 receives the laser signal reflected or scattered by the workpiece and calculates parameters such as the diameter and roundness of the workpiece. The turntable 11 can rotate during operation, allowing different angle positions of the workpiece to enter the measurement range of the diameter gauge in sequence, realizing multi-point detection of the workpiece from all directions.
