[0029] A clamping assembly is arranged on the base 1, and the clamping assembly is distributed along the circumference of the workpiece 16, and the clamping assembly clamps the workpiece 16 in the vertical direction;

[0030] The positioning components are arranged on the base 1 and are used to position and clamp the workpiece 16 . The positioning components are distributed on both sides of the workpiece 16 .

[0031] The workpiece 16 is installed on the base 1 through the installation component, and the positioning component positions and clamps the workpiece 16 from both sides of the workpiece 16 to ensure that the processing position of the workpiece 16 will not shift. Finally, the clamping component presses the workpiece 16 on the base 1 in the vertical direction to prevent the workpiece 16 from rotating and shifting during the processing. It can adapt to the shape of the reducer shell, position and clamp the reducer shell, and meet the processing and production requirements of the reducer shell.

[0032] In this example, see Figure 1 and Figure 2 The mounting assembly includes a mounting seat 6, a positioning column 20 is arranged at the center of the mounting seat 6, the positioning column 20 matches the workpiece 16, a plurality of support columns 14 are arranged circumferentially of the mounting seat 6, the workpiece 16 is passed through the positioning column 20 for positioning, and the support columns 14 support the workpiece 16.

[0033] Specifically, a second connecting member 5 is also penetrated on the mounting seat 6, and the second connecting member 5 connects the mounting seat 6 to the base 1. In the present embodiment, the mounting seat 6 is a disc structure, and the positioning column 20 and the support column 14 are both cylindrical structures. The support columns 14 are distributed in an array along the circumference of the mounting seat 6, and the height of the positioning column 20 is greater than the height of the support column 14. When the workpiece 16 is installed, the workpiece 16 is mounted on the positioning column 20, and the bottom of the workpiece 16 contacts the support column 14. The positioning column 20 can prevent the workpiece 16 from falling off the support column 14 during the installation process. The specific structure of the positioning column 20 and the support column 14 is not limited herein.

[0034] In detail, the support column 14 is also provided with an avoidance hole 15 for avoiding when drilling a workpiece 16 , and the avoidance hole 15 of the support column 14 corresponds to the drilling position of the workpiece 16 .

[0035] In this example, see Figure 1 and Figure 2 The clamping assembly includes a plurality of clamping blocks 7 , each of which is provided with an adjusting groove 12 , and each of which is provided with a locking member. The locking member locks the clamping block 7 , and the clamping block 7 presses the workpiece 16 onto the supporting column 14 .
