[0027] The use method and advantages of the utility model: When the combined clamping assembly is used, the working process is as follows:

The transmission structure is used to make the right cylinder body fixture 10 inserted into the circular through hole of the left cylinder body fixture 9, and the internal workpiece is tightened in real time under extrusion. When the workpiece needs to maintain a fixed structure, the driven turntable 7 and the left vertical plate 4 are fixed by the second limit screw 13, and the bottom of the steering seat 1 is turned on. The servo motor 11 can make the adjustment seat 3 drive the upper part to rotate horizontally to adjust the angle, turn the first limit screw 12, rotate the steering seat 1 to adjust the angle, and reverse the first limit screw 12 again to fix the steering seat 1 and the mounting seat 2. When the cylinder body on the workpiece surface needs to be processed, the left cylinder body clamp 9 and the right cylinder body clamp 10 are disassembled, and the cylinder head clamp 14 is threadedly installed on the surfaces of the active turntable 8 and the driven turntable 7 respectively. The shaft heads at both ends of the workpiece can be inserted into the circular grooves in the cylinder head clamp 14, and the internal adjustment block 1401 is telescopically fitted to the outer wall of the workpiece due to the structure of the spring 1402.
