[0087] Step 2: Begin clamping the split-type compartment 11. The specific process is as follows:

Turn on the pneumatic switch of the multi-point support device 10 to allow the support head on the multi-point support device 10 to move freely. Place the split-type cabin 11 to be processed on the multi-point support high-efficiency clamping device. The split-type cabin 11 has four process chucks on each side (eight in total). The four process chucks near the large end and the small end are placed on the adjusting support table 603, and the remaining four chucks are placed on the support table 404.

[0089] The second step is to rotate the clamping plate 407 and the positioning block 502 back to their original positions.

When the measured value of the touch detection head 501 is 0.1N, stop raising the adjustment support platform 603. At this time, the vertical position of the split-type cabin 11 is adjusted.

[0090] The third step is to activate the four lifting cylinders 403 to raise the support platform 404 until it detects contact with the process chuck of the split-type cabin 11, then stop raising the support platform 404, activate the clamping cylinder 409 to lower the clamping plate 407 to clamp the process chuck of the split-type cabin 11, and close the pneumatic switch of the multi-point support device 10 to fix the support head on the multi-point support device 10. At this time, the split-type cabin 11 is clamped in the vertical position.

[0091] The fourth step is to screw 110 to rotate 104 and fine-tune the axial positioning of the split-type compartment 11 so that it coincides with the Y-axis direction of the machining tool. At this time, the axial position of the split-type compartment 11 is adjusted, thus completing the overall clamping and alignment of the split-type compartment 11.
