[0026] The height adjustment mechanism includes a second bevel gear 11, a second motor 12 and a first bevel gear 13. The second bevel gear 11 is coaxially arranged on the side wall of the rotating cylinder 10. The second motor 12 is fixedly installed on the mounting frame. The output end of the second motor 12 is coaxially fixedly connected to the first bevel gear 13. The first bevel gear 13 is coaxially fixedly connected to the second bevel gear 11. The first bevel gear 13 is driven by the output end of the second motor 12 to mesh with the second bevel gear 11, so that the rotating cylinder 10 rotates. Since the connecting rod 14 is closely arranged with the inner wall of the mounting cavity of the rotating cylinder 10 through the connecting disk, the friction force of the connecting disk on the inner wall of the mounting cavity is greater than the sum of its own gravity and the external force loaded, so that the connecting rod 14 drives the friction wheel 15 to rotate.

[0027] The height adjustment mechanism also includes a third motor 18, a spur gear 19 and a rack 17. The third motor 18 is fixedly mounted on the inner wall of the mounting cavity. The output end of the third motor 18 is coaxially fixedly connected to the spur gear 19. The rack 17 is fixedly connected to the connecting plate. The spur gear 19 is meshed with the rack 17 for transmission. When it is necessary to perform wear resistance inspection on other surfaces of the sealing plug, the spur gear 19 is driven to mesh with the rack 17 through the output end of the third motor 18, so that the rack 17 pulls the connecting rod 14 to move the friction wheel 15 away from the arc-shaped clamping piece 9, so that a pair of arc-shaped clamping pieces 9 can drive the sealing plug to flip.

[0028] Reference Figure 1 and Figure 2 , automatic flipping mechanisms are provided on both sides of the friction wheel 15, and the automatic flipping mechanisms are used to fix the sealing plug and automatically flip the sealing plug, so as to facilitate and quickly adjust the sealing plug to perform wear resistance detection on other sides, which is beneficial to improving the wear resistance detection efficiency of the sealing plug;

[0029] The automatic flipping mechanism includes a fourth motor 6, a pair of rotating shafts 7 and a pair of bearings 8. The fourth motor 6 is fixedly installed on one of the moving platforms 5. The pair of rotating shafts 7 are respectively arranged on a pair of moving platforms 5 through a pair of bearings 8. The bearings 8 are one-way rotating bearings. The output end of the fourth motor 6 is coaxially fixedly connected to one of the rotating shafts 7. A pair of arc-shaped clamping pieces 9 are respectively fixedly connected to the pair of rotating shafts 7. The rotating shaft 7 is driven to rotate by the output end of the fourth motor 6, so that the rotating shaft 7 drives the arc-shaped clamping piece 9 fixedly connected thereto to drive the sealing plug to rotate.

[0030] Reference Figure 1 and Figure 2 A mounting frame is provided at the bottom of the base 1, and a rotating cylinder 10 is rotatably connected to the mounting frame. A mounting cavity is provided in the rotating cylinder 10, and a connecting rod 14 is coaxially provided in the mounting cavity. One end of the connecting rod 14 away from the rotating cylinder 10 is coaxially fixedly connected to the friction wheel 15, and one end of the connecting rod 14 located in the mounting cavity is coaxially fixedly connected to the connecting disk, and the outer wall of the connecting disk is tightly arranged with the inner wall of the mounting cavity.

[0031] Reference Figure 3 and Figure 4 A through hole 16 is provided on the connecting rod 14, and the forward and reverse screw rods 3 are inserted into the through hole 16. The effect of such a setting is that when the connecting rod 14 moves up and down, the rotation of the forward and reverse screw rods 3 is not affected.

[0032] Reference Figure 1 and Figure 2 The slide groove 2 is provided with a forward and reverse screw rod 3, and a first motor 4 is fixedly installed on the side wall of the base 1. The output end of the first motor 4 is coaxially fixedly connected with the forward and reverse screw rod 3. A pair of sliders are symmetrically arranged in the slide groove 2, and a pair of sliders are respectively provided with matching threaded holes corresponding to the threads on the forward and reverse screw rod 3. The pair of sliders are respectively fixedly connected to a pair of moving platforms 5. The forward and reverse screw rod 3 is driven to rotate by the output end of the first motor 4, so that the pair of sliders in the slide groove 2 respectively drive a pair of arc-shaped clamping pieces 9 to move relatively in the slide groove 2, thereby realizing fixed clamping of the side wall of the sealing plug.

[0033] The working principle of the utility model is as follows:

[0034] By placing the sealing plug on the friction wheel 15, the output end of the third motor 18 drives the spur gear 19 to mesh with the rack 17, so that the rack 17 pushes the connecting rod 14 to move the upper surface of the friction wheel 15 to be flush with the bottom end of the pair of arc-shaped clamping pieces 9, and the output end of the first motor 4 drives the forward and reverse screw rods 3 to rotate, so that the pair of sliders in the slide groove 2 respectively drive the pair of arc-shaped clamping pieces 9 to move relatively in the slide groove 2, so as to achieve fixed clamping of the side wall of the sealing plug, and then the output end of the second motor 12 drives the first bevel gear 13 and the second bevel gear 11 to mesh with each other, so that the rotating cylinder 10 rotates. Since the connecting rod 14 is in close contact with the inner wall of the installation cavity of the rotating cylinder 10 through the connecting disk, It is arranged that, since the value of the upward friction force exerted on the connecting disk by the inner wall of the installation cavity is greater than the sum of the value of its own gravity and the external force it carries, the connecting rod 14 drives the friction wheel 15 to rotate. When it is necessary to perform wear resistance test on other surfaces of the sealing plug, the output end of the third motor 18 drives the spur gear 19 to engage with the rack 17 for transmission, so that the rack 17 pulls the connecting rod 14 to make the friction wheel 15 away from the arc-shaped clamping piece 9, so that a pair of arc-shaped clamping pieces 9 can drive the sealing plug to flip, and the output end of the fourth motor 6 drives the rotating shaft 7 to rotate, so that the rotating shaft 7 drives the arc-shaped clamping piece 9 fixedly connected thereto to drive the sealing plug to rotate, so as to facilitate the rapid adjustment of the sealing plug for wear resistance test on other sides.
