[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a device for measuring the thickness of a rubber sealing plug. (Refer to...) Figure 1-3 A rubber sealing plug thickness measuring device includes a fixed frame 1, a placement platform 2 fixedly connected to the outer wall of the fixed frame 1, a plurality of sliding grooves 11 opened on the outer wall of the placement platform 2, the plurality of sliding grooves 11 being evenly distributed in a circumferential array at equal intervals, a slider 12 slidably connected to the inner wall of the sliding groove 11, a clamping block 17 installed at the top of the slider 12, and a positioning mechanism for driving the plurality of clamping blocks 17 to move relative to each other installed on the bottom outer wall of the placement platform 2.

[0023] An electric push rod 3 is fixedly installed on the top outer wall of the fixed frame 1. The output end of the electric push rod 3 passes through the fixed frame 1 and is equipped with a measuring head 4. A pressure sensor 5 is fixedly installed on the top middle outer wall of the placement platform 2. The measuring head 4 is located directly above the pressure sensor 5.

[0024] A control box 6 is fixedly installed on the outer wall of the mounting bracket 1. A display screen 7 is installed on the outer wall of the control box 6, and a controller 8 is installed inside it. The controller 8 is electrically connected to the measuring head 4 and the pressure sensor 5.

[0025] The positioning mechanism includes a triangular rotating disk 10 rotatably connected to the outer wall of the bottom center of the placement platform 2 via a fixed shaft 9. Multiple ends of the multiple triangular rotating disks 10 are rotatably connected to connecting rods 14. Multiple sliders 12 are fixedly connected to the outer wall of their bottoms with connecting blocks 13. One end of the multiple connecting rods 14 away from the triangular rotating disks 10 is hinged to the multiple connecting blocks 13.

[0026] The positioning mechanism also includes an electric telescopic rod 16 that is fixedly installed on the outer wall of the placement platform 2 via a mounting plate 15. The output end of the electric telescopic rod 16 is movably connected to the outer wall of one of the connecting blocks 13 via a connector.

[0027] The electric telescopic pole 16 is electrically connected to the controller 8 via a connecting wire.

[0028] The outer wall of the clamping block 17 is provided with multiple adjustment holes 18, and a screw 19 is provided on the inner wall of one of the adjustment holes 18. The screw 19 is threadedly connected to the top outer wall of the slider 12.

[0029] The implementation principle of the rubber sealing plug thickness measuring device in this application embodiment is as follows: The rubber sealing plug is placed on the pressure sensor 5. Through the positioning mechanism, the electric telescopic rod 16 is activated. The output end of the electric telescopic rod 16 pushes a connecting block 13 to move inward. At this time, the connecting block 13 pushes a connecting rod 14 inward. The connecting rod 14 is set at a slight inclination. When the connecting rod 14 is pushed, it rotates. The inclination angle of the connecting rod 14 becomes correct, and its distance becomes shorter. The connecting rod 14 then pulls or pushes the triangular rotating disk 10 to rotate around the fixed axis 9. At this time, the multiple ends of the triangular rotating disk 10 simultaneously pull or push multiple connecting rods 14 to rotate. The multiple connecting rods 14 then simultaneously pull multiple connecting blocks 13 to slide inward. The multiple connecting blocks 13 drive the slider 12 to slide inside the slide groove 11. The slider 12 then drives multiple clamping blocks 17 to move closer and retract inward until the rubber sealing plug is clamped and fixed, thereby stably positioning the rubber sealing plug.

[0030] After the rubber sealing plug is fixed, the electric push rod 3 is activated by the controller 8, which pushes the measuring head 4 downward. After the measuring head 4 contacts the rubber sealing plug, the pressure sensor 5 begins to detect pressure changes. When the pressure reaches the preset value, it indicates that the measuring head 4 is in full contact with the rubber sealing plug and the appropriate measuring pressure has been applied. At this time, the electric push rod 3 stops descending, and the pressure sensor 5 transmits the pressure data to the controller 8. The controller 8 calculates the thickness of the rubber sealing plug based on the downward distance of the measuring head 4 and displays the data on the display screen 7. After the measurement is completed, the electric push rod 3 moves the measuring head 4 upward to reset, and the output end of the mounting plate 15 retracts, causing the positioning mechanism to reset and release the clamp on the rubber sealing plug, allowing the measurement of the next rubber sealing plug to proceed.

[0031] It is worth noting that the measuring head 4 is connected to an external displacement measuring device (such as a grating ruler, linear encoder, etc., or in practice, it can also be achieved through the displacement control and feedback system of the electric push rod 3). Combined with the signal from the pressure sensor 5 that the pressure reaches the set value, the distance that the measuring head 4 presses down can be accurately measured. This distance is the thickness of the rubber sealing plug.
