[0018] As attached Figure 1 -Attached Figure 4As shown, the detection platform 1 includes a fixing mechanism and a motor 7 are arranged on the upper part of the detection platform 1, the motor 7 is driven and connected to a support arm 8, a lifting mechanism is installed at one end of the support arm 8 away from the motor 7, a fixing frame 11 is arranged on the lifting mechanism, a motor 3 12 is installed on the fixing frame 11, the motor 3 12 is driven and connected to a rotating block 13, a rotating arm 14 is installed at the lower part of the rotating block 13, two detectors 15 are installed on the rotating arm 14, and the two detectors 15 are arranged opposite to each other.

[0019] The cylindrical part is fixed by the scale line 29. The height of the detector 15 is adjusted so that the detector 15 can contact the cylindrical part. The two detectors 15 are respectively located on the inner and outer sides of the cylindrical part. The motor 3 12 drives the rotating block 13 to rotate, and the rotating block 13 then drives the two detectors 15 to rotate through the rotating arm 14. The two detectors 15 move along the inner wall and outer wall of the cylindrical part respectively, thereby completing the detection of the inner wall and outer wall of the cylindrical part.

[0020] By driving the support arm 8 to rotate through the motor 7, the lifting mechanism, the rotating arm 14, and the detector 15 can be moved away from the top of the fixing part 2, so as not to hinder the cylindrical part from being placed on the detection platform 1. After the cylindrical part is fixed by the fixing part 2, the motor 7 drives the support arm 8 to rotate, so that the detector 15 reaches the top of the cylindrical part and starts the detection.

[0021] As attached Figure 2 As shown, an adjustment hole 17 is provided on the rotating arm 14, and a mounting frame 16 is connected to the rear side of the detector 15.

The mounting frame 16 is fixed to the rotating arm 14 by the cooperation of the fixing bolt 18 and the fixing nut 19. The mounting frame 16 can move along the adjustment hole 17, thereby adjusting the positions of the two detectors 15, so that the two detectors 15 can contact the inner wall and the outer wall of the cylindrical member respectively for detection.

[0022] As attached Figure 3 , 4As shown, the detector 15 includes a mounting block 20, a mounting groove 21 is provided inside the mounting block 20, a roller frame 25 is slidably provided in the mounting groove 21, a spring 24 is connected between the roller frame 25 and the mounting block 20, a detection wheel 26 is rotatably provided on the part of the roller frame 25 located outside the mounting block 20, a marking line 27 is provided on the upper part of the roller frame 25, an opening 28 is provided on the upper part of the mounting block 20 for the marking line 27 to be exposed, and a scale line 29 is provided on the side of the opening 28 on the mounting block 20. The detection wheel 26 contacts the inner wall or outer wall of the cylindrical member, and when the rotating arm 14 drives the detector 15 to rotate, the detection wheel 26 rolls along the inner wall or outer wall of the cylindrical member, and if there is a bulge on the inner wall or outer wall, the detection wheel 26 will be squeezed, so that the roller frame 25 moves outward; if there is a depression on the inner wall or outer wall, the roller frame 25 will drive the detection wheel 26 to move inward under the action of the spring 24. An identification line 27 is provided on the roller frame 25. By observing the movement of the identification line 27 and comparing it with the scale line 29, it can be determined whether the movement of the identification line 27 exceeds the limit, that is, whether the cylinder is compliant, thereby completing the test and obtaining the test result.

[0023] A protective piece made of a transparent material is installed on the opening 28 , which can not only allow the identification line 27 to be normally observed, but also prevent external impurities from entering the installation groove 21 through the opening 28 .

[0024] A guide rod 22 is provided in the mounting groove 21, and a guide block 23 is connected to the side of the roller frame 25, and the guide block 23 is sleeved on the guide rod 22.

The screw 30 is driven forward and reversed by the motor 2 10 to drive the screw nut to rise and fall, thereby driving the detector 15 on the rotating arm 14 to rise and fall.

[0026] The fixing mechanism includes a plurality of fixing members 2, which are evenly distributed in a circular shape on the testing platform 1, and the number of fixing members 2 is at least three, so that the cylindrical member can be fixed and centered at the same time. The fixing member 2 includes a support block 5 fixedly connected to the testing platform 1, and a sliding groove 4 is provided on the testing platform 1 at a position outside the support block 5, and a top block 3 is slidably provided in the sliding groove 4, and a support block 5 is connected between the top block 3 and the support block 5. The top block 3 can only move along the direction in which the sliding groove 4 is opened, which can avoid the displacement of the position of the top block 3. After the cylindrical member is placed on the testing platform 1, the top block 3 is pressed against the inner wall of the cylindrical member under the action of the spring 6, thereby completing the fixing of the cylindrical member.
