Specifically, this clamping device is suitable for the processing of various shaft parts, including but not limited to turning, milling, and grinding.

[0003] The main task of the clamping device is to stably clamp the shaft to ensure that it maintains a precise position and posture during the processing process. This plays a vital role in ensuring processing accuracy, improving production efficiency, and reducing scrap rates. The clamping device is also suitable for automated production lines and can be used in conjunction with CNC machine tools, robots and other equipment to achieve automated processing of shaft parts, which can further improve production efficiency, reduce manual intervention, and reduce operational difficulty and safety hazards.

[0004] Although a clamping device for shaft processing plays an important role in mechanical manufacturing and processing industries, it still has some defects. Different shaft sizes and shapes may require specific clamping devices, which increases manufacturing costs and the time for replacing fixtures. In addition, the clamping device is not suitable for shafts of certain special shapes, which limits its scope of application. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Specific examples are given below.

[0020] See also Figures 1-4 The utility model provides a clamping device for shaft processing, including a base 1, two sets of clamping mechanisms are fixedly arranged on the top of the base 1 in a mirror image, the clamping mechanism includes a cylinder 2, a limit plate 5 is fixedly installed on the top of the cylinder 2, the limit plate 5 is fixed by a limit screw 4, a moving rod 6 is movably installed inside the limit plate 5, a triangular block 19 is provided in the middle of the moving rod 6, a mounting assembly 17 is fixedly installed on the top of the moving rod 6, a middle pulley 901 is embedded in the mounting assembly 17, and two fixed rods are fixed on both sides of the moving rod 6. A limit block 18 is installed on one side of the limit block 18, and a pulley 9 is installed on the top and bottom ends of the clamping block 8. The pulley 9 is fixed by a rotating rod 16. During operation, the output end of the cylinder 2 drives the moving rod to move upward. When the output end of the cylinder 2 lifts the pulley 9 and reaches the maximum angle, it is the maximum clamping angle of the clamping mechanism. When an object is clamped, the pulleys at the top and bottom ends of the clamping block 8 slide on the triangular block 19 to expand the clamping angle. When the clamped shaft is completely clamped, the heights of the left and right sides are consistent, and the clamped shaft is concentric.

[0021] Furthermore, a support column 10 is installed on one side of the base 1, and a second cylinder 11 is fixedly installed on the bottom side of the top of the support column 10, and a motor 12 is fixedly installed on the output end of the second cylinder 11, and a fixed block 13 is fixedly installed on the output end of the motor 12, and a mounting block 14 is installed on the bottom end of the fixed block 13, and a drill bit 15 is installed on the surface of the mounting block 14. During operation, when the shaft body needs to be processed, the second cylinder 11 pushes the motor 12 to move downward, and the drill bit driven by the rotation of the output end of the motor 12 rotates downward to contact the shaft body to process the shaft body.

[0022] Furthermore, U-shaped fixing plates 3 are installed on both sides of the base, the mounting components on both sides are coaxial, the two groups of clamping blocks are arranged in a mirror image, and the mounting components of the U-shaped fixing plates 3 on both sides are coaxial.

[0023] Furthermore, the limit plate 5 and the triangular block 19 are located on the same plane, and the triangular block 19 and the limit block 18 are located on the same plane. During operation, the weight of the shaft will be transmitted to the moving rod 6, and the moving rod 6 sinks and drives the triangular block 19 to move downward. The setting of the limit block 5 is to limit the maximum clamping angle.

[0024] Working principle: The output end of the cylinder 2 drives the moving rod to move upward. When the output end of the cylinder 2 lifts the pulley 9 and reaches the maximum angle, it is the maximum clamping angle of the clamping mechanism. When an object is clamped, the pulleys at the top and bottom ends of the clamping block 8 slide on the triangular block 19 to expand the clamping angle. When the clamped shaft is completely clamped, the heights of the left and right sides are consistent, and the clamped shaft is concentric. When the shaft needs to be processed, the weight of the shaft will be transferred to the moving rod 6, and the moving rod 6 sinks and drives the triangular block 19 to move downward. The second cylinder 11 pushes the motor downward, and the output end of the motor 12 rotates to drive the mounting block 14 to rotate. The rotation of the mounting block 14 drives the drill bit 15 to rotate downward to contact the shaft to process the shaft.
