[0030] like Figure 1 and Figure 2 As shown, a lifting vibration isolation column consists of a supporting outer cylinder assembly, a servo electric cylinder assembly, a telescopic supporting cylinder assembly, and an air spring flexible assembly as the main structure. However, during assembly, the order needs to be adjusted according to the structural characteristics. During assembly, it is carried out from the inside out and from bottom to top. The specific steps are as follows:

[0031] Step 1: After the servo electric cylinder mounting flange 7 is connected to the servo electric cylinder body 4 through the mounting bolts 23 and the mounting nuts 14, the servo electric cylinder mounting flange 7 is connected to one end of the servo electric cylinder mounting support tube 5 through the mounting bolts 23, and the other end of the servo electric cylinder mounting support tube 5 is connected to the first flange 6 through the mounting bolts 23, and finally the external thread of the top head 2 of the servo electric cylinder screw is screwed into the threaded hole at the top of the servo electric cylinder screw 3;

[0032] Step 2: The bottom end (the end with the notch) of the third supporting outer cylinder 1 is connected to the fifth flange 12 by fastening screws, and the top end is connected to the first flange 6 assembled in step 1 by installing connecting bolts 23;

[0033] Step 3: One end of the second supporting outer cylinder 13 is connected to the third flange 14 by fastening screws, and the other end of the second supporting outer cylinder 13 is connected to the second flange 9 by fastening screws, and then the second flange 9 is connected to the first flange 6 in step 2 by installing connecting bolts 23 and installing connecting nuts 14;

[0034] Step 4: The two anti-friction materials 10 are pasted in the corresponding positioning grooves of the first supporting outer cylinder 8 by a polymer adhesive. After the adhesive is completely solidified, the bottom end of the first supporting outer cylinder 8 is connected to the fourth flange 15 by fastening screws, and then the assembled fourth flange 15 is connected to the third flange 14 in step 3 by installing connecting bolts 23 and installing connecting nuts 14;

[0035] Step 5: Paste the special adhesive of the magnetic scale 21 into the corresponding groove of the telescopic cylinder 36.

Then install the reading head mounting seat 20 and the reading head 19 into the magnetic scale detection port 21 corresponding to the first supporting outer cylinder 8 through the fastening screws, and adjust to the appropriate distance;

[0036] Step 6: Install the air spring 22 to the top of the telescopic cylinder 36 by bolts, then install the height valve mounting plate 25 and the height valve 26 to the corresponding position of the air spring 22 by bolts, and install the connecting mounting plate 30 to the top of the air spring 22 by bolts.

Then fasten each connection support position of the platform or frame to the connection mounting plate 30 of the lifting vibration isolation column with bolts (note that the lifting vibration isolation column is in the 0 position state without lifting during the installation process); finally, connect and debug the circuit and air circuit of each lifting vibration isolation column.

[0041] When the installed platform or frame rises, the user only needs to click the up button on the computer screen, and the computer system will automatically and uniformly control the rise of each lifting vibration isolation column; first, the brakes of each servo electric cylinder brake system are released, and then each servo electric cylinder screw 3 rises synchronously, and the servo electric cylinder screw head 2 at the top lifts the telescopic support tube assembly; during the rising process, each lifting vibration isolation column is detected in real time by the servo electric cylinder screw position sensor and the telescopic support tube assembly position sensor, and the feedback is fed back to the computer system. When there is a difference in the lifting height values ​​of each lifting vibration isolation column, the computer system automatically adjusts the lifting vibration isolation column for fine-tuning to ensure the lifting height Consistent; after reaching the required height, the user only needs to click the stop button on the computer screen, and the servo electric cylinder screw rods 3 of each lifting and vibration isolation column will stop rising synchronously, and the servo electric cylinder brake system will hold the brakes tightly; if the user does not click the stop button on the computer screen, the servo electric cylinder screw rods 3 of each lifting and vibration isolation column will rise synchronously to the maximum stroke of the servo electric cylinder screw rod 3 and then stop automatically, and the servo electric cylinder brake system will hold the brakes tightly; after the lifting and vibration isolation column has finished rising, click the inflation button on the computer screen, and each air spring flexible component will start to inflate, and the inflation will stop after it reaches the height set by the height valve 26. At this time, the platform or frame is in a state of flexible support and vibration isolation.

[0042] When the platform or frame is descending, the user clicks the exhaust button on the computer screen, and each air spring flexible component starts to exhaust. After the internal gas is completely emptied, that is, when there is no exhaust sound, click the down button on the computer screen, and the computer system will automatically and uniformly control the descent of each lifting and vibration isolation column; first, the brake system of each servo electric cylinder is released, and then the lead screw 3 of each servo electric cylinder is synchronously descended, and its telescopic support cylinder assembly is descended together with the top servo electric cylinder lead screw head 2 under the action of gravity; during the descent process, each lifting and vibration isolation column is affected by the servo electric cylinder lead screw position sensor and the telescopic support cylinder assembly position sensor. The sensors are set to detect in real time and feed back to the computer system. When there is a difference in the descent height values ​​of each lifting and vibration isolation column, the computer system automatically adjusts the lifting and vibration isolation column for fine-tuning to ensure that the descent height is consistent; when the required height is reached, the user only needs to click the stop button on the computer screen, and the servo electric cylinder screw rod 3 of each lifting and vibration isolation column will stop descending synchronously, and the servo electric cylinder brake system will hold the brake tightly; if the user does not click the stop button on the computer screen, the servo electric cylinder screw rod 3 of each lifting and vibration isolation column will synchronously descend to the 0 position of the servo electric cylinder screw rod 3 and then stop automatically, and the servo electric cylinder brake system will hold the brake tightly.
