[0025] Embodiment

[0026] As Figures 1-4 shown, a conveying device for hot rolling piercing plug detection, including top rod trolley 1, main shaft 2 and rotating drive device. Top rod trolley 1 is provided with the through hole along its moving direction, and the main shaft 2 is rotationally connected with the through hole. One end of the main shaft 2 is provided with the limit connecting block 4 located outside the through hole, and the limit connecting block 4 is provided with the connecting piece for being connected with the top rod. The other end of the main shaft 2 is connected with the rotating drive device, and the rotating drive device includes the shell 5 fixedly connected with the side wall of the top rod trolley 1, and the shell 5 is provided with the through hole 6 opposite to the main shaft 2 on the side wall away from the top rod trolley 1, and the shell 5 is connected with the top rod trolley 1 by flange in the embodiment.

[0027] The outer wall of the shell 5 is provided with the worm 8 connected with the rotating power device 3, and the rotating power device 3 is a motor, and a fixed speed and adjustable speed twelve shaft optical shaft motor is used in the embodiment. The specific connection mode of the worm 8 and the shell 5 can be that the shell 5 is provided with the bearing seat 9 and the mounting plate 10 oppositely, the mounting plate 10 is fixedly connected with the rotating power device 3, one end of the worm 8 is connected with the output shaft of the rotating power device 3, and the other end of the worm 8 is connected with the bearing seat 9.

[0028] The housing 5 contains a worm gear 11, whose teeth pass through the clearance hole 7 on the housing 5 and mesh with the worm 8. The inner ring of the one-way clutch 12 is fixedly connected to the main shaft 2, for example, by a key. The worm gear 11 is fixedly connected to the outer ring of the one-way clutch 12. For example, a first bushing 13 is provided on one side of the one-way clutch 12, located in a limiting groove on the side wall of the push rod trolley 1. A second bushing 14 is provided on the other side of the one-way clutch 12. The second bushing 14 is tightened and fixed to the one-way clutch 12 by a lock nut 15 and a stop washer 16. A pressure cap 17 is fitted on the second bushing 14, which is in close contact with the worm gear 11 and the one-way clutch 12, and is fixedly connected to the worm gear 11 by bolts. The inner wall of the housing 5 is sealed to the main shaft 2 by an oil seal 18, which is located on the side of the lock nut 15 away from the one-way clutch 12. In this embodiment, the one-way clutch is a one-way bearing.

[0029] Before use, connect the mandrel to the limiting connecting block 4, and then install the mandrel on the mandrel. During use, the drive shaft that drives the mandrel to rotate for piercing passes through the through hole 6 and connects to the main shaft 2 to ensure that the mandrel can perform normal hot rolling piercing. During hot rolling piercing, due to the action of the one-way clutch 12, the main shaft 2, mandrel, and mandrel rotate, while the worm gear 11 is stationary. At this time, the rotation speed of the mandrel is a high-speed rotation that meets the requirements of the piercing process. After each hot rolling is completed, the mandrel carriage 1 moves the mandrel to the camera of the machine vision inspection device, and then the rotation power device 3 is started, causing the worm 8 to drive the worm gear 11 to rotate. At this time, the rotation speed of the main shaft 2, mandrel, and mandrel is a low-speed rotation that meets the requirements of the mandrel damage detection process. Since the mandrel can achieve 360-degree low-speed rotation under the transmission of the worm gear 11 and worm 8, only one camera is needed in the machine vision inspection device to achieve all-round, blind-angle-free automated inspection of the mandrel.

[0030] Therefore, the conveying device for inspecting hot-rolled piercing mandrels with the above-mentioned structure can be used in conjunction with machine vision inspection equipment to achieve all-round, blind-angle-free automated inspection of the mandrels, while effectively reducing the space occupied by the equipment during mandrel inspection.
