The roller shaft is an important part of the belt conveyor, mainly used to support the conveyor belt, bear the weight of the material, and ensure the smooth operation of the conveyor belt. When repairing and replacing the roller shaft, the role of the clamping fixture is particularly important. In batch production or production line operations, fast clamping of workpieces can reduce non-machining time, thereby improving overall production efficiency.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a quick-loading and quick-discharging roller shaft clamping tool, including a base 1, a fixed plate 2 is fixedly connected inside the base 1, a motor 3 is fixedly connected to the bottom of the fixed plate 2, a driving wheel 4 is fixedly connected to the output end of the motor 3, the outer wall of the driving wheel 4 is rotatably connected to the inside of the fixed plate 2, a double-sided gear ring 5 is rotatably connected inside the fixed plate 2, the driving wheel 4 is meshed with the double-sided gear ring 5, the fixed plate 2 is rotatably connected to a driven wheel 6, the double-sided gear ring 5 is meshed with the driven wheel 6, a spur rack 7 is slidably connected inside the fixed plate 2, the driven wheel 6 is meshed with the spur rack 7, the outer wall of the spur rack 7 is slidably connected to the inside of the base 1, a limiting assembly is provided on the outer wall of the spur rack 7, a sliding support 9 is fixedly connected to the upper surface of the base 1, the limiting assembly includes a limiting strip 8, the outer wall of the limiting strip 8 is fixedly connected to the outer wall of the spur rack 7, and the outer wall of the limiting strip 8 is slidably connected to the inside of the base 1 and the fixed plate 2;

[0025] Specifically, first, the output end of the motor 3 is used to drive the driving wheel 4 to rotate inside the fixed plate 2. The precise engagement between the driving wheel 4 and the double-sided gear ring 5 enables the double-sided gear ring 5 to rotate accordingly with the rotation of the driving wheel 4, thereby ensuring the smoothness and accuracy of the rotation. The rotation of the double-sided gear ring 5 further drives the four driven wheels 6 to rotate synchronously. The driven wheel 6 is connected to the spur rack 7. Therefore, when the driven wheel 6 rotates, the spur rack 7 will slide inside the fixed plate 2. Then, the limit bar 8 is used to ensure the stability and accuracy of the sliding of the spur rack 7, which can limit the displacement of the spur rack 7 during the sliding process to ensure its linear motion. The sliding of the spur rack 7 then drives the sliding support 9 to move. A clamp 13 is installed above the sliding support 9. When the sliding support 9 moves to the specified position, the clamp 13 can accurately clamp the workpiece, thereby achieving positioning and fixation of the workpiece.

[0026] Reference Figure 1 , Figure 3 and Figure 4 The interior of the sliding support 9 is rotatably connected with a transmission rod 11, one end of the transmission rod 11 is fixedly connected with a handle 10, the other end of the transmission rod 11 is fixedly connected with a rotating disk 14, the outer wall of the sliding support 9 is slidably connected with a mounting seat 12, the outer wall of the mounting seat 12 is fixedly connected with a clamp 13, and a mounting hole 18 is opened inside the mounting seat 12. The outer wall of the rotating disk 14 is rotatably connected to the interior of the sliding support 9, and the interior of the rotating disk 14 is slidably connected with a sliding rod 15. The outer wall of the sliding rod 15 is fixedly connected with a card block 16, and the outer wall of the card block 16 is slidably connected to the interior of the transmission rod 11 and the mounting seat 12. The card block 16 is slidably connected to the interior of the mounting hole 18, the outer wall of the card block 16 is fixedly connected to a limiting block 17, and the outer wall of the limiting block 17 is slidably connected to the interior of the transmission rod 11;

[0027] Specifically, first operate the driving handle 10. When the driving handle 10 is rotated, the transmission rod 11 will rotate accordingly, and its other end will be closely connected with the rotating disk 14. As the transmission rod 11 rotates, the rotating disk 14 starts to rotate. An arc-shaped slide groove is provided inside the rotating disk 14, allowing four slide rods 15 to slide smoothly inside it. When the rotating disk 14 rotates, the slide rod 15 will move along the arc-shaped slide groove. The sliding of the slide rod 15 further drives the movement of the block 16. The block 16 can slide freely inside the sliding support 9 and the mounting seat 12, ensuring the stability and accuracy of the block 16 during the movement. The existence of the limit block 17 provides necessary guidance for the movement of the block 16, ensuring that it moves according to a predetermined trajectory, thereby realizing the rapid disassembly and replacement of the clamp 13 of the mounting seat 12 and its outer wall.

[0028] Working principle: When the quick-install and quick-release roller shaft clamping fixture is needed, first, the output end of the motor 3 drives the driving wheel 4 to rotate inside the fixed plate 2, so that the double-sided gear ring 5 rotates with the rotation of the driving wheel 4, and then the rotation of the double-sided gear ring 5 drives the four driven wheels 6 to rotate, thereby driving the four spur racks 7 to slide inside the fixed plate 2. In this process, the movement of the spur rack 7 is guided by the limit bar 8, and then the spur rack 7 drives the sliding support 9 and the clamp 13 above the sliding support 9 to clamp and fix the workpiece, achieving The workpiece is positioned and fixed, and then the driving handle 10 drives the transmission rod 11 to rotate inside the sliding support 9, so that the rotating disk 14 is driven to rotate through one end of the transmission rod 11, and then the four sliding rods 15 slide in the arc-shaped slide groove inside the rotating disk 14, and then the sliding of the sliding rod 15 drives the clamping block 16 to slide inside the sliding support 9 and the mounting seat 12. In this process, the clamping block 16 is guided by the limit block 17, thereby achieving the effect of disassembling and replacing the mounting seat 12 and the clamp 13 on the outer wall of the mounting seat 12.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
