[0016] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:

[0017] Please refer to Figure 1 and Figure 2A large roller expansion sleeve locking device includes a frame 10, an adjustment assembly 20 is provided above the frame 10, and a support frame 30 is provided above the adjustment assembly 20. The adjustment assembly 20 drives the support frame 30 to move in the X-axis and Y-axis directions. A positioning rod 40 is provided on one side of the support frame 30. The positioning rod 40 is slidably connected to the support frame 30 through a mounting frame 50. The mounting frame 50 can move up and down along the support plate. A mounting plate 60 is provided at one end of the positioning rod 40 away from the support frame 30, and the positioning rod 40 passes through the mounting plate 60. A rotating motor 70 is provided on the mounting plate 60. The rotating motor 70 drives the positioning rod 40 to rotate. A locking assembly 80 is provided on the mounting plate 60, and the locking assembly 80 extends toward the side of the mounting plate 60 away from the support frame 30.

[0018] Please refer to Figure 3 , move the assembled barrel skin and center shaft to one side of the frame 10, and insert the expansion sleeve between the barrel skin and the center shaft, align the positioning rod 40 on the support frame 30 with the axis of the center shaft through the adjustment component 20, so that the positioning rod 40 and the center shaft are located on the same axis, align the locking component 80 on the mounting plate 60 with the bolts on the expansion sleeve for locking, and use the rotating motor 70 to adjust the angle of the locking component 80, so that it can be rotated along the axis of the expansion sleeve to lock multiple bolts, thereby realizing automatic locking and improving locking efficiency.

[0019] In the above scheme, the adjustment component 20 includes an X-axis slide rail 21, a sliding plate 22 and a Y-axis slide rail 23. The X-axis slide rail 21 is arranged on the surface of the frame 10, the sliding plate 22 is slidably arranged on the surface of the X-axis slide rail 21, and the Y-axis slide rail 23 is arranged on the surface of the sliding plate 22, forming an L-shaped structure. The bottom of the support frame 30 is slidably connected to the Y-axis slide rail 23, and the mounting frame 50 is in a U-shaped structure. A Z-axis slide rail 31 is provided on one side of the support frame 30, and the mounting frame 50 is horizontally slidably arranged on the Z-axis slide rail 31, and the positioning rod 40 passes through both ends of the mounting frame 50.

[0020] Through the X-axis slide rail 21, the Y-axis slide rail 23 and the Z-axis slide rail 31, the locking assembly 80 on the mounting frame 50 can be adjusted in multiple directions, so that the positioning rod 40 can be accurately aligned with the axis of the central axis. As for how to drive the sliding plate 22, the support frame 30 and the mounting frame 50 to move, existing moving components such as screw assemblies, cylinders, push rod motors and other existing technologies can be used to achieve this, and therefore, it is not limited in this solution.

[0021] A counterweight block 41 is provided at one end of the positioning rod 40 close to the mounting frame 50, and the counterweight block is used to balance the forces at both ends of the positioning rod 40 to prevent the positioning rod 40 from tipping over to one side because the other end of the positioning rod 40 is set on the locking assembly 80 and the mounting plate 60.

[0022] There are two locking assemblies 80, which are relatively arranged on the surface of the mounting plate 60, and an adjustment slide rail 61 is provided along the mounting plate 60. The locking assemblies 80 are slidably arranged on the adjustment slide rail 61, so that the two locking assemblies 80 can be used to lock the expansion sleeve at the same time, and when the positioning rod 40 is driven to rotate by the rotating motor 70, the two locking assemblies 80 also rotate synchronously, thereby improving the locking efficiency, and the forces acting on the two locking assemblies 80 during the tightening process play a role in offsetting each other, reducing the inertia force on the positioning rod 40.

[0023] The adjustment assembly 20 includes a slide 81, a locking motor 82, a sleeve 83 and a locking rod 84. The slide 81 is slidably set on the adjustment track. The mounting plate 60 is provided with a slide groove 62 corresponding to the adjustment track. The sleeve 83 is fixed on the slide 81, and the sleeve 83 extends through the slide groove 62 to the side of the mounting plate 60 away from the support frame 30. The locking motor 82 is fixed to one end of the sleeve 83. The locking rod 84 is fixedly connected to the output shaft of the locking motor 82, and the locking rod 84 extends out of the sleeve 83.

[0024] The locking motor 82 drives the locking rod 84 in the sleeve 83 to rotate, and one end of the locking rod 84 is inserted into the bolt in the expansion sleeve, driving the bolt to rotate, thereby achieving the purpose of locking. The slide 81 can be used to adjust the distance between the locking assembly 80 and the positioning rod 40, thereby adjusting it according to the position of the bolt on the expansion sleeve.

[0025] The utility model provides an expansion sleeve locking device for a large roller. The assembled drum skin and the center shaft are moved to one side of a frame, and the expansion sleeve is clamped between the drum skin and the center shaft. The positioning rod on the support frame is aligned with the axis of the center shaft by adjusting the assembly so that the positioning rod and the center shaft are located on the same axis. The locking assembly on the mounting plate is aligned with the bolts on the expansion sleeve for locking. The angle of the locking assembly can be adjusted by using a rotating motor, so that multiple bolts can be rotated along the axis of the expansion sleeve to lock, thereby realizing automatic locking and improving locking efficiency.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
