Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , a coreless grinder loading device in this embodiment, includes a vertical plate 1, a top plate 2 is arranged at the top of the vertical plate 1, two first electric push rods 3 are arranged at the top of the top plate 2, a lifting plate 4 located in front of the vertical plate 1 is fixedly installed between the driving ends of the two first electric push rods 3, an electric fixture 7 is movably installed at the bottom of the lifting plate 4, and an angle adjustment mechanism 5 and a moving mechanism 6 are arranged at the top of the electric fixture 7.

[0024] The angle adjustment mechanism 5 includes a second electric push rod 501, the second electric push rod 501 is fixedly installed at the top of the lifting plate 4, a toothed plate 502 is fixedly installed at the driving end of the second electric push rod 501, a gear 503 is meshed with the front side of the toothed plate 502, a rotating rod 504 is fixedly installed at the bottom of the gear 503, and a turntable 505 is fixedly installed at the bottom of the rotating rod 504.

[0025] When using the angle adjustment mechanism 5 to adjust the angle of the electric fixture 7, first drive the toothed plate 502 to move left and right through the second electric push rod 501, the toothed plate 502 drives the meshed gear 503 to rotate, the gear 503 drives the rotating rod 504 to rotate, and the rotating rod 504 drives the turntable 505 to rotate. Since the electric fixture 7 is fixedly connected to the turntable 505 through three connecting rods, when the turntable 505 rotates, it drives the electric fixture 7 to rotate, so that the clamping direction of the electric fixture 7 and the angle at which the workpiece is placed on the coreless grinder can be changed.

[0026] The moving mechanism 6 includes a motor 601. The motor 601 is fixedly installed on the left side of the lifting plate 4. A threaded rod 602, which is rotationally connected to the right inner wall of the lifting plate 4, is fixedly installed at the output shaft of the motor 601. A limiting rod 603 is fixedly installed between the left and right inner walls of the lifting plate 4. A moving block 604 is movably installed between the outer surfaces of the threaded rod 602 and the limiting rod 603.

[0027] Since the bottom of the rotating rod 504 sequentially penetrates through the moving block 604 and the bottom opening 605 and is fixedly connected to the turntable 505, when the moving block 604 moves left and right, it will also drive the gear 503, the rotating rod 504, the turntable 505, and the electric fixture 7 to move left and right. After the gear 503 is moved to the position of the toothed plate 502, through the drive of the second electric push rod 501, the angle of the electric fixture 7 can be adjusted under the left and right movement of the toothed plate 502.

[0028] When using the moving mechanism 6 to adjust the horizontal position of the electric fixture 7, first, the motor 601 drives the threaded rod 602 to rotate. The threaded rod 602 drives the moving block 604 to move left and right within the top opening, thereby driving the electric fixture 7 to move left and right.

[0029] During implementation, the operation is carried out in the following steps:

[0030] 1) When the electric fixture 7 is at the leftmost end, the two first electric push rods 3 can drive the electric fixture 7 to move up and down to clamp the workpiece.

[0031] 2) Then, after the workpiece is clamped from the conveyor belt, the angle adjustment mechanism 5 drives the electric fixture 7 to move to the rightmost end. When it is necessary to change the placement position of the electric fixture 7, by starting the angle adjustment mechanism 5, the electric fixture 7 is driven to rotate to a suitable angle.

[0032] 3) Finally, the workpiece is placed at the machining position of the centerless grinder.

[0033] In summary, for this centerless grinder loading device, by setting the angle adjustment mechanism 5, under the meshing of the toothed plate 502 and the gear 503, the electric fixture 7 can rotate, thereby changing the clamping angle and the placement angle of the electric fixture 7. This design makes the loading device have higher flexibility and adaptability, and can adjust the angle of the electric fixture 7 and the placement angle of the workpiece according to different processing requirements.

[0034] Furthermore, by setting the moving mechanism 6, the electric fixture 7 can be driven to move left and right. After clamping the workpiece on the conveyor belt, it is moved to the machining position of the centerless grinder to the right.
