(For the convenience of description and understanding, hereinafter Figure 2Above is the description of the upper part). Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1-2 , the present invention provides a technical solution: a cylindrical roundness detection device, including a bracket 1, the bracket 1 is arranged on one side of the cylinder 12, the cylinder 12 is placed on a frustum 13 at its lower end, and through calibration during the placement process, the cylinder 12 is located at the middle position of the frustum 13, which is convenient for the roundness detector 8 to detect. A driving rotation mechanism 14 for controlling its rotation is arranged at the lower end of the frustum 13. The driving rotation mechanism 14 includes a base 141, a rotation motor 142, a driving gear 143, a driven gear 144 and a rotating shaft 145. The base 141 is arranged below the frustum 13.

The rotation motor 142 is fixed on the upper end surface of the base 141. The output shaft of the rotation motor 142 is connected with the driving gear 143. The driven gear 144 is sleeved on the outer side surface of the rotating shaft 145. The driving gear 143 is meshed and connected with the driven gear 144. By driving the driving gear 143 to rotate by the rotation motor 142, the driven gear 144 is driven to rotate, and then the rotating shaft 145 and the frustum 13 are driven to rotate. The cylinder 14 rotates together with the frustum 13, so that the roundness detector 8 detects the roundness of the cylinder 12 for one week;

[0020] A hydraulic lifting rod 6 is arranged at the upper end of the bracket 1. The upper end of the hydraulic lifting rod 6 is connected with a lifting plate 3. A horizontal displacement mechanism 5 is fixed on the upper surface of the lifting plate 3. The lower end of the horizontal displacement mechanism 5 is connected with a support plate 7. A roundness detector 8 is fixed on the upper end of the support plate 7. The roundness at different height positions of the cylinder can be measured under the action of the hydraulic lifting rod 6, and multiple measurements improve the measurement accuracy;

[0021] The horizontal displacement mechanism 5 includes a fixed box 51, a moving block 52, a screw rod 53 and a driving motor 54. An opening is formed at the lower end of the fixed box 51. The screw rod 53 is arranged in the fixed box 51. The moving block 52 is threadedly connected to the outer side surface of the screw rod 53. One end of the screw rod 53 passes through the fixed box 51 and is connected with the output end of the driving motor 54. The lower end of the moving block 52 is fixedly connected with the support plate 7. By driving the screw rod 53 to rotate by the driving motor 54, the moving block 52 is driven to move linearly, so that the detection head of the roundness detector 8 contacts the surface of the cylinder 12, which is convenient for measurement.

[0024] Further, in order to improve the lifting smoothness of the lifting plate 3, a sliding sleeve 11 is arranged between the vertical rod 2 and the lifting plate 3.

[0025] Further, in order to prevent the lifting plate 3 from slipping off the vertical rod 2, a limiting plate 4 is arranged at the top of the vertical rod 2.

[0026] Further, in order to avoid being affected by the vibrations of other surrounding machines during the detection process, the bracket 1 is a cubic structure, the inside of the bracket 1 is hollow, and the bracket 1 is made of wood material, which can play a good role in shock absorption.

[0027] During use: Place the cylinder 12 to be detected on the frustum 13, use an auxiliary positioning tool to ensure that the cylinder 12 is located at the center of the frustum 13, control the driving motor 54 to start through the control switch 10, drive the screw rod 53 to rotate, and then make the moving block 52 move, so that the detection head of the roundness detector 8 contacts the outer side surface of the cylinder 12. Then turn on the rotating motor 142, and drive the frustum 13 to rotate under the meshing action of the driving gear 143 and the driven gear 144, so that the roundness detector 8 detects the roundness of the entire circumference of the cylinder 12; when it is necessary to detect at different height positions, control the lifting of the hydraulic lifting rod 6 to adjust the height of the roundness measuring instrument 8 for detection.

[0028] The utility model can detect the outer roundness of a large cylinder 12. Without the aid of a ladder, under the action of the driving and rotating mechanism 14, it is convenient for the roundness detector 8 to detect the roundness, improving the detection convenience; by setting the hydraulic lifting rod 6, the roundness of different height positions of the cylinder 12 can be detected, and multiple detections improve the detection accuracy.
