The pull rods are respectively passed through the holes at the four corners of the front end cover and then to the holes at the four corners of the rear end cover. There are four pull rods around the cylinder. The four corners of the front end cover and the rear end cover are pre-tightened with nuts to fix the pull rods on the front end cover and the rear end cover. Then the front end cover clamping assembly 41 is rotated to the appropriate position to clamp the front end cover, and then the rear end cover clamping assembly 42 is rotated to the appropriate position to clamp the rear end cover. This can ensure that the four sides of the front end cover and the rear end cover of the cylinder are kept on the same horizontal plane during assembly, thereby ensuring the quality and stability of production.
