[0026] When the clamping assembly fixes the workpiece, first, the driving part one 2 drives the driving part two 21 to move upward, then the driving part two 21 drives the clamping part to rotate, and when the clamping part is pressed downward to abut against the upper end surface of the workpiece, the fixing operation of the workpiece is completed. When the clamping part needs to be avoided, the driving part two 21 drives the clamping part to rotate until the clamping part is separated from the upper end surface of the workpiece and avoids the upper side space of the workpiece.

[0027] In order to reduce the space occupation, the driving end of the driving part one 2 is located at the lower side thereof, the driving end of the driving part one 2 is fixed with a plate body, the driving part two 21 is installed on the plate body, and the driving end of the driving part one 2 is telescopic to drive the plate body to move longitudinally and drive the driving part two 21 to move longitudinally.

In the drilling and milling process of the workpiece, in order to reduce the local stress concentration of the workpiece and reduce the deformation of the workpiece under the action of the local stress, it is necessary to make the fixing position close to the processing position. Under different processing requirements of the workpiece, the processing position changes, and in order to ensure the processing quality of the workpiece, it is necessary to flexibly adjust the fixing position according to the change of the processing requirement.

[0029] The mounting block 26 is detachably connected with the clamping arm 24, the lower side end surface of the clamping arm 24 is provided with a plurality of connection positions for connecting with the mounting block 26, the mounting block 26 can be fixed with each connection position by means of plug-in connection or threaded connection, and when the processing position changes, the relative assembly position of the mounting block 26 and the clamping arm 24 can be adjusted to adjust the relative fixing position of the fixing block 25 and the workpiece.
