Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, the present invention provides a clamping device for a ball mill, including a base 1 and a movable frame 2. The bottom of the movable frame 2 is movably connected to the top of the base 1. A support rod 3 is provided on the outer side of the movable frame 2. Several support rods 3 are provided and are distributed in a rectangular shape at equal intervals. One end of the support rod 3 near the inner side of the movable frame 2 passes through the movable frame 2 and extends to the inner side of the movable frame 2. The support rod 3 is movably connected to the movable frame 2. A limit component 4 is provided on the outer side of the end of the support rod 3 away from the inner side of the movable frame 2.

[0022] As a technical optimization of this utility model, by setting the limiting component 4, the fixed shell 41 can limit the limiting ring 42, and the limiting ring 42 can limit the support rod 3, thereby preventing the support rod 3 from moving left and right and getting off the movable frame 2.

[0023] refer to Figure 2 The protective mechanism 5 includes a nylon elastic fabric 51, a polyester fabric 52 is fixedly connected to the inner side of the nylon elastic fabric 51, a spring 53 is fixedly connected to the outer side of the limiting ring 42, the other end of the spring 53 is fixedly connected to the outer side of the inner wall of the fixed shell 41, and the inner wall of the spring 53 is movably connected to the surface of the support rod 3.

[0024] As a technical optimization of this utility model, by setting up a protective mechanism 5, the nylon elastic cloth 51 can prevent the workpiece from directly contacting the support rod 3. At the same time, when the workpiece squeezes the nylon elastic cloth 51, it can drive multiple support rods 3 to move, thus making it easy to adapt to workpieces of various shapes. The polyester cloth 52 can prevent the workpiece from scratching and damaging the nylon elastic cloth 51.

[0025] refer to Figure 1 and Figure 2 The bottom of the movable frame 2 is fixedly connected to a movable plate 6. Movable grooves 7 are provided on the left and right sides of the top of the base 1. The inner wall of the movable groove 7 is movably connected to the surface of the movable plate 6.

[0026] As a technical optimization of this utility model, by setting up a movable plate 6 and a movable groove 7, the left and right movement of the movable frame 2 can drive the movable plate 6 to move left and right inside the movable groove 7. The movable groove 7 can limit the movement of the movable plate 6 and the movable frame 2 in the front and back, thereby improving the stability of the movement of the movable frame 2.

[0027] refer to Figure 3 A rotating rod 8 is provided on both the left and right sides of the base 1. The end of the rotating rod 8 near the movable frame 2 passes through the base 1 and the movable plate 6 in sequence and is movably connected to the inner side of the inner wall of the movable groove 7 through a bearing. The rotating rod 8 is movably connected to the base 1 and threadedly connected to the movable plate 6.

[0028] As a technical optimization of this utility model, by setting a rotating rod 8, the movable plate 6 can be limited, and by rotating the rotating rod 8, the movable plate 6 can be moved left and right, thereby improving the convenience of moving the movable frame 2.

[0029] refer to Figure 1 A connecting seat 9 is fixedly connected to the rear side of the base 1, and a placement plate 10 is movably connected to the top of the front side of the connecting seat 9 via a hinge.

[0030] As a technical optimization of this utility model, by setting a connecting seat 9 and a placement plate 10, the connecting seat 9 can limit the movement of the placement plate 10, and by flipping the placement plate 10 to the top of the base 1, the workpiece can be temporarily supported.

[0031] refer to Figure 1 A support plate 11 is fixedly connected to the bottom of the rear side of the placement plate 10. A screw 12 is provided on the top of the support plate 11. The end of the screw 12 near the connecting seat 9 passes through the support plate 11 and the connecting seat 9 in sequence and extends into the interior of the connecting seat 9. The screw 12 is threadedly connected to the support plate 11 and the connecting seat 9.

[0032] As a technical optimization of this utility model, by setting a support plate 11 and a screw 12, the screw 12 can fix and limit the support plate 11, and the fixed and limited support plate 11 can fix and limit the placement plate 10, thereby enabling the placement plate 10 to be temporarily positioned.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to clamp the workpiece, first rotate the screw 12 to disengage it from the support plate 11 and the connecting seat 9, then flip the placement plate 10 to position it on top of the base 1. Next, place the workpiece to be measured on top of the placement plate 10, and then rotate the two rotating rods 8 in sequence to move the movable plate 6 and the movable frame 2 towards the workpiece. When the two sides of the workpiece contact the polyester cloth 52 and the movable frame 2 continues to move, the workpiece can squeeze the support rod 3. At this time, the support rod 3, which moves to different degrees, can use the nylon elastic cloth 51 and the polyester cloth 52 to clamp the two sides of the workpiece. Clamping and positioning utilizes the elasticity and resilience of the nylon elastic cloth 51 to improve the overall movement of multiple support rods 3. The multiple support rods 3 can move to different degrees according to the different shapes of the workpiece, thus facilitating the user to clamp and position workpieces of different shapes. At this time, the support rods 3 moving outward can drive the limiting ring 42 to move and compress the spring 53. The user can use an external ball mill to detect the coating thickness of the workpiece. After the detection is completed, the rotating rod 8 is rotated in the opposite direction to drive the two movable frames 2 away from the workpiece. At this time, the spring 53 returns to its original position and pushes the limiting ring 42 and the support rods 3 back to their original positions, thus facilitating subsequent workpiece inspection.

[0034] In summary, this ball mill clamping device, by setting up support rods 3, allows the two movable frames 2 to move inward when the workpiece is placed inside, enabling the insertion rod to support both sides of the workpiece. This solves the problem that in existing ball mills, traditional clamping devices can effectively fix workpieces with flat or regular curved surfaces, ensuring measurement accuracy. However, for irregularly shaped workpieces with complex geometries, traditional clamping methods are difficult to apply, leading to easy movement or deformation of the workpiece during measurement, thus affecting the accuracy of the measurement results.
