[0029] The elastic member includes a plurality of fixed columns 34 fixedly mounted on the bottom of the mounting plate 29. A groove 35 is provided at the bottom of the fixed column 34. A first movable column 36 is slidably provided in the groove 35. The bottom end of the first movable column 36 is fixedly connected to the second support plate 32. The top end of the first movable column 36 is connected to the groove 35 via a first spring 37.

[0030] The rotating support structure includes a rotating frame 38 rotatably sleeved on the outside of the detection rod 8, and the rotating frame 38 is located above the sealing cover 5, and the top of the sealing cover 5 is contacted with a supporting ring 39, and the top of the supporting ring 39 is in contact with the bottom of the rotating frame 38, and the top of the sealing cover 5 is fixedly connected with a plurality of limiting columns 40, and the rotating frame 38 and the supporting ring 39 are both provided with a plurality of limiting grooves 41 adapted to the limiting columns 40, and the limiting columns 40 respectively penetrate the limiting grooves 41 on the supporting ring 39 and the rotating frame 38, and the bottom of the supporting ring 39 is fixedly connected with a plurality of second movable columns 52, and the bottom end of the second movable column 52 is fixedly connected with a first fixed disk 42 located in the sealing cover 5, and the top of the first fixed disk 42 and the top inner wall of the sealing cover 5 are connected by a second spring 43; At the same time, two stop columns 46 are provided at the top contact of the rotating frame 38, and the outer sliding sleeve of the stop column 46 is provided with a support part 45, and the bottom of the support part 45 is fixedly connected to the top of the sealing cover 5.

[0031] It can be understood that when the inspection cup 4 rotates to the inspection station and the position adjustment mechanism drives the rotating seat 3 and the inspection cup 4 to move upward, the sealing cover 5 drives the detection rod 8, the first support plate 30 and the positioning column 31 to move upward, and the top of the positioning column 31 is a truncated cone structure. When the value of the position deviation between the positioning hole 33 and the positioning column 31 is within a certain range, the top of the positioning column 31 is gradually inserted into the positioning hole 33, and the positioning column 31 and the first support plate 30 are rotated and corrected relative to the second support plate 32, and finally the positioning column 31 passes through the positioning hole 33. When the value of the position deviation between the positioning hole 33 and the positioning column 31 exceeds a preset value, as the first support plate 30 and the positioning column 31 move upward, the positioning column 31 pushes the second support plate 32 to move upward synchronously, the second support plate 32 and the first movable column 36 move upward relative to the fixed column 34, and the first spring 37 is in a compressed state; When the detection rod 8 and the first support plate 30 move up to a preset height, the staff can drive the detection rod 8 and the first support plate 30 to rotate relative to the second support plate 32. When the positioning column 31 moves to the bottom of the positioning hole 33, the first spring 37 pushes the first movable column 36 and the second support plate 32 to move downward, so that the positioning column 31 passes through the positioning hole 33. When the inspection machine body 2 drives the mounting plate 29 to rotate, the mounting plate 29 drives the positioning column 31, the first support plate 30 and the detection rod 8 to rotate synchronously through the fixed column 34, the first movable column 36 and the second support plate 32, and the detection rod 8 rotates relative to the rotating frame 38 and the sealing cover 5.

[0032] It should be noted that the method of using the above-mentioned high hydrogen silicone oil viscosity testing device of the present invention is as follows: The staff places the test cup 4 filled with high hydrogen silicone oil on the rotating seat 3 at the loading and unloading station, locates the position of the test cup 4 by the positioning ring 25, covers the sealing cover 5 on the top of the test cup 4, drives the rotating seat 3 to rotate by the position adjustment mechanism, so that the test cup 4 rotates to the heating and stirring station, and the position adjustment mechanism drives the rotating seat 3 and the test cup 4 to move up to a preset height, stirs the high hydrogen silicone oil in the test cup 4 by the stirring mechanism, and heats the high hydrogen silicone oil in the test cup 4 by the heating plate 7; When the high-hydrogen silicone oil is heated to the preset inspection temperature, the position adjustment mechanism drives the rotating seat 3 and the inspection cup 4 to descend to the initial height, and the rotating seat 3 is driven to rotate by the position adjustment mechanism to rotate the inspection cup 4 to the inspection station, and the position adjustment mechanism drives the rotating seat 3 and the inspection cup 4 to move up to the preset height, and the detection rod 8 is connected to the driving shaft on the inspection machine body 2 through the synchronous connector, and the inspection machine body 2 drives the detection rod 8 to rotate synchronously, thereby realizing the viscosity inspection of the high-hydrogen silicone oil. When the high-hydrogen silicone oil inspection is completed, the position adjustment mechanism drives the rotating seat 3 and the inspection cup 4 to descend to the initial height, and the connection between the detection rod 8 and the driving shaft on the inspection machine body 2 is released through the synchronous connector, and the position adjustment mechanism drives the inspection cup 4 to move to the loading and unloading station, and the staff removes the inspection cup 4 after the inspection is completed. The staff does not need to disassemble and assemble the detection rod 8, and the heating and inspection of the high-hydrogen silicone oil can be automatically completed, reducing the waiting time of the inspection machine body 2.

[0033] In the above process, the staff puts the bottom end of the test cup 4 into the positioning ring 25, covers the sealing cover 5 on the top of the test cup 4, and the sealing cover 5 drives the guide block 13 to slide into the guide groove 12 through the connecting plate 14, and drives the first rotating shaft 9 to rotate through the first servo motor 10. The first rotating shaft 9 can drive the sealing cover 5, the test cup 4 and the rotating seat 3 to rotate relative to the lifting seat 26 as a whole through the guide block 13 and the connecting plate 14, and the roller 28 at the bottom of the rotating seat 3 rolls on the lifting seat 26. The design of the roller 28 reduces the resistance encountered by the rotating seat 3 when rotating relative to the lifting seat 26. When the rotating seat 3 and the test cup 4 rotate to the preset position, the lifting seat 26 and the rotating seat 3 are driven to move up synchronously through the hydraulic telescopic rod 27, and the test cup 4 and the sealing cover 5 drive the guide block 13 to slide in the guide groove 12 through the connecting plate 14; When the inspection cup 4 rotates to the heating and stirring position, and the position adjustment mechanism drives the rotating seat 3 and the inspection cup 4 to move up to the preset height, the top of the corresponding first damping disk 21 and the bottom of the second damping disk 24 are in contact, and the second servo motor 23 drives the second damping disk 24 to rotate. The second damping disk 24 drives the first damping disk 21, the connecting shaft 20 and the second gear 19 to rotate through the friction force. The second gear 19 can drive the remaining first gears 18 to rotate synchronously through the ring gear 51. The first gear 18 drives the stirring blade 16 to stir the high-hydrogen silicone oil through the second rotating shaft 15, so that the high-hydrogen silicone oil is heated evenly; When the inspection cup 4 rotates to the inspection station and the position adjustment mechanism drives the rotating seat 3 and the inspection cup 4 to move upward, the sealing cover 5 drives the detection rod 8, the first support plate 30 and the positioning column 31 to move upward, and the top of the positioning column 31 is a truncated cone structure. When the value of the position deviation between the positioning hole 33 and the positioning column 31 is within a certain range, the top of the positioning column 31 is gradually inserted into the positioning hole 33, and the positioning column 31 and the first support plate 30 are rotated and corrected relative to the second support plate 32, and finally the positioning column 31 passes through the positioning hole 33. When the value of the position deviation between the positioning hole 33 and the positioning column 31 exceeds a preset value, as the first support plate 30 and the positioning column 31 move upward, the positioning column 31 pushes the second support plate 32 to move upward synchronously, and the second support plate 32 The first movable column 36 moves up relative to the fixed column 34, and the first spring 37 is in a compressed state. When the detection rod 8 and the first support plate 30 move up to a preset height, the staff can drive the detection rod 8 and the first support plate 30 to rotate relative to the second support plate 32. When the positioning column 31 moves to below the positioning hole 33, the first spring 37 pushes the first movable column 36 and the second support plate 32 to move down, so that the positioning column 31 passes through the positioning hole 33. When the inspection machine body 2 drives the mounting plate 29 to rotate, the mounting plate 29 drives the positioning column 31, the first support plate 30 and the detection rod 8 to rotate synchronously through the fixed column 34, the first movable column 36 and the second support plate 32, and the detection rod 8 rotates relative to the rotating frame 38 and the sealing cover 5.

[0034] It should be noted that when it is necessary to remove the detection rod 8, the staff pulls the second fixed plate 47 and the stop column 46 to move, and the third spring 48 is in a stretched state, so that the stop column 46 is no longer in contact with the top of the rotating frame 38, and the second spring 43 is in a stretched state at this time. Since the stop column 46 no longer limits the position of the rotating frame 38, the second spring 43 can drive the first fixed plate 42, the second movable column 52 and the support ring 39 to move upward, and the support ring 39 can push the rotating frame 38 and the detection rod 8 relative to the sealing cover 5 and the limiting column 40 move upward synchronously. When the top horizontal position of the rotating frame 38 is higher than the bottom horizontal position of the stopping column 46, the staff releases the second fixing plate 47, and the third spring 48 applies a pulling force to the second fixing plate 47 and the stopping column 46, so that the stopping column 46 abuts against the side wall of the rotating frame 38. The staff pulls the detection rod 8 upward so that the rotating frame 38 is no longer located between the two stopping columns 46, and the rotating frame 38 is separated from the limiting column 40, and the detection rod 8 no longer penetrates the sealing cover 5, and the removal of the detection rod 8 is completed; Then, the staff drives the two adjacent nuts 6 to rotate so that the two adjacent nuts 6 no longer clamp the fixing plate 49, release the fixing relationship between the fixing plate 49 and the screw 50, and the staff drives the inspection machine body 2 and the fixing plate 49 to move vertically relative to the screw 50, changing the initial height of the inspection machine body 2, and ensuring that the inspection machine body 2 is in the preset position; After the position of the inspection machine body 2 is adjusted, the staff drives the two adjacent nuts 6 to rotate so that the two adjacent nuts 6 clamp the fixing plate 49, so that the inspection machine body 2 and the fixing plate 49 are fixed relative to the screw rod 50 and the inspection table 1.
