[0026] A method for using an outer diameter inspection tool for a plastic disk. When using the outer diameter inspection tool for a plastic disk, the method for using the outer diameter inspection tool for a plastic disk is required, including the following steps:

[0027] S1: Install a mounting frame at the telescopic end of the lifting component. Then, install the bidirectional adjustment lead screw driven by the driving device inside the mounting frame. By rotating the bidirectional adjustment lead screw, two internal thread blocks can be driven to approach and move away from each other, so that two auxiliary wheels with soft materials on their outer surfaces can contact the top of the plastic disc, restricting the plastic disc from above. During this process, the stability of the movement of the internal thread blocks can be increased through the slide bars. The two external detection devices and the two internal detection devices are driven by the fourth telescopic components, enabling them to simultaneously detect the upper and lower parts of the inner and outer surfaces of the plastic disc, improving the detection efficiency. At the same time, the two external detection devices and the two internal detection devices cooperate with each other to simultaneously detect the same position on the inner and outer surfaces of the plastic disc, preventing the plastic disc from deforming due to the thrust of the detection devices, which is beneficial to improving the accuracy of the detection data;

[0028] S2: During detection, first install the two external detection devices and the two internal detection devices on two sets of support frames at different heights through the fourth telescopic components. Then, place the plastic disc on the top of the rotating disc, and center the plastic disc on the top of the rotating disc with the assistance of two auxiliary components. Then, start the lifting component to push the mounting frame downward, and at the same time start the driving device to drive the bidirectional adjustment lead screw to rotate, thereby adjusting the positions of the two auxiliary wheels to align them with the top of the plastic disc and making the top of the plastic disc snap into the grooves of the auxiliary wheels. Then, start the four fourth telescopic components to make the two external detection devices and the two internal detection devices approach the inner and outer surfaces of the plastic disc respectively, and then the auxiliary components reset;

[0029] S3: After completing the preparation work, the driving component can be started to drive the rotating disc at the top of the rotating bolt to rotate through the transmission component and the driven component, thereby driving the plastic disc to perform circular motion. During this process, the auxiliary wheels will roll on the top of the plastic disc to limit the plastic disc and prevent displacement. At the same time, the two external detection devices and the two internal detection devices can synchronously detect the upper and lower parts of the inner and outer surfaces of the plastic disc.

[0030] Compared with the related technologies, the plastic disc outer circle inspection tool and its usage method provided by the present invention have the following beneficial effects:

[0031] The present invention provides an outer diameter inspection tool for a plastic disc. In order to avoid deformation of the plastic disc during the outer diameter inspection process and improve the inspection accuracy, an installation frame is installed at the telescopic end of the lifting assembly. Then, a bidirectional adjustment screw rod driven by a driving device is installed inside the installation frame. By rotating the bidirectional adjustment screw rod, two internal thread blocks can be driven to approach and move away from each other, so that two auxiliary wheels with soft materials on their outer surfaces can contact the top of the plastic disc to restrict the plastic disc from above. During this process, the stability of the movement of the internal thread blocks can be increased through the sliding rods. The two outer inspection devices and the two inner inspection devices are driven by the fourth telescopic component, so that they can simultaneously inspect the inner surface and the outer surface of the plastic disc in the upper half and the lower half at the same time to improve the inspection efficiency. At the same time, the two outer inspection devices and the two inner inspection devices cooperate with each other to simultaneously inspect the same position on the inner and outer surfaces of the plastic disc, avoiding deformation of the plastic disc due to the thrust of the inspection device, which is beneficial to improving the accuracy of the inspection data.

[0058] S1: Install an installation frame 14 at the telescopic end of the lifting component 11. Then, install the bidirectional adjustment lead screw 19 driven by the driving device 15 inside the installation frame 14. By rotating the bidirectional adjustment lead screw 19, two internal thread blocks 20 can be driven to approach and move away from each other, so that two auxiliary wheels 22 with soft materials on their outer surfaces can contact the top of the plastic disc, restricting the plastic disc from above. During this process, the sliding rod 34 can increase the stability of the movement of the internal thread block 20. The two external detection devices 29 and the two internal detection devices 31 are driven by the fourth telescopic component 33, enabling them to simultaneously detect the upper and lower parts of the inner and outer surfaces of the plastic disc, improving the detection efficiency.

At the top of the sealing pipe 45, an exhaust head 42 is fixedly connected. At the bottom of the sealing pipe 45, a rotary connector 41 is installed.

[0070] The mounting hole 44 penetrates through the rotating bolt 24 and the top of the inner wall of the inspection table 16. The sealing pipe 45 seals the mounting hole 44. The rotary connector 41 can supply gas during the rotation process, enabling the sealing pipe 45 to be normally connected to the exhaust pipe 40 during both the rotation process and when it is not rotating.

[0071] On the top of the bottom plate 1, an exhaust assembly 39 is installed. At the inlet of the exhaust assembly 39, an exhaust pipe 40 is installed.

The bottom end of the sealing pipe 45 is connected to the exhaust pipe 40 at the inlet of the exhaust assembly 39 through a rotatable rotary connector 41, which can realize the exhaust of the sealing pipe 45 during the rotation process and ensure the sealing performance. When in use, first place the plastic disc above the positioning disk 36, then center it through the auxiliary assembly 8. After completion, start the exhaust assembly 39 to provide suction to form a negative pressure between the bottom of the plastic disc and the positioning disk 36, so that the plastic disc can be adsorbed on the positioning disk 36. The cooperation with the auxiliary wheel 22 can increase the stability of the plastic disc during the detection process.

10. A method for using an outer diameter inspection tool for a plastic disc, characterized in that, Including the outer circle detector for plastic discs according to any one of claims 1-9, the outer circle detector for plastic discs needs to use the usage method of the outer circle detector for plastic discs when in use, including the following steps: S1: Install an installation frame at the telescopic end of the lifting component. Then, install the bidirectional adjustment lead screw driven by the driving device inside the installation frame. By rotating the bidirectional adjustment lead screw, two internal thread blocks can be driven to approach and move away from each other, so that two auxiliary wheels with soft materials on their outer surfaces can contact the top of the plastic disc, restricting the plastic disc from above. During this process, the stability of the movement of the internal thread blocks can be increased through the slide bar. The two external detection devices and the two internal detection devices are driven by the fourth telescopic component, enabling them to simultaneously detect the upper and lower parts of the inner and outer surfaces of the plastic disc, improving the detection efficiency. At the same time, the two external detection devices and the two internal detection devices cooperate with each other to simultaneously detect the same position on the inner and outer surfaces of the plastic disc, preventing the plastic disc from deforming due to the thrust of the detection devices, which is beneficial to improving the accuracy of the detection data; S2: During detection, first install the two external detection devices and the two internal detection devices on two sets of support frames at different heights through the fourth telescopic component. Then, place the plastic disc on the top of the rotating disc, and center the plastic disc on the top of the rotating disc with the assistance of two auxiliary components. After that, start the lifting component to push the installation frame downward, and at the same time start the driving device to drive the bidirectional adjustment lead screw to rotate, thereby adjusting the positions of the two auxiliary wheels to align them with the top of the plastic disc and making the top of the plastic disc snap into the grooves of the auxiliary wheels. Then, start the four fourth telescopic components to move the two external detection devices and the two internal detection devices close to the inner and outer surfaces of the plastic disc respectively, and then the auxiliary components reset; S3: After completing the preparation work, the driving component can be started to drive the rotating disc at the top of the rotating bolt to rotate through the transmission component and the driven component, thereby driving the plastic disc to perform circular motion. During this process, the auxiliary wheels will roll on the top of the plastic disc to limit the position of the plastic disc to prevent displacement. At the same time, the two external detection devices and the two internal detection devices can synchronously detect the upper and lower parts of the inner and outer surfaces of the plastic disc.
