[0023] In use, the cylinder 301, end position sensor 13, top position sensor 623, head roller drive module 50, and drive motor 631 are all electrically connected to the control system. When a different model of head 40 needs to be replaced, the quick clamp 65 is opened, the drive motor 631 is started, and the output plate 62 is raised, causing the upper positioning pin 4111 to disengage from the upper positioning hole 621. Then, the cylinder 301 is started, causing the left and right slide plates 20 of the head 40 to slide out along the left and right slide rails 111. Then, the robotic arm is used to lift the head 40 by holding the lifting rings 25 and 438, causing the lower positioning pin 21 to disengage from the lower positioning hole 4211. The original head 40 is then removed. Next, the robotic arm is used to lift the required head 40 and place it on the left and right slide plates 20, allowing the lower positioning pin 21 to insert into the lower positioning hole 4211. Then, the cylinder 301 is started. 1. This causes the left and right slide plates 20 of the new machine head 40 to slide in along the left and right slide rails 111. When the positioning shaft wheel 12 is accommodated in the positioning notch 22 and abuts against the inner sidewall of the positioning notch 22, the end position sensor 13 senses the right end position of the left and right slide plates 20 and obtains the positioning information. After receiving the signal, the control system stops the cylinder 301 from moving, then starts the drive motor 631 to drive the output plate 62 to move down, so that the upper positioning post 4111 is inserted into the upper positioning hole 621. When the bottom of the output plate 62 is in contact with the top of the upper substrate 411, the top position sensor 623 senses the top position of the upper substrate 411 and obtains the positioning information. After receiving the signal, the control system stops the drive motor 631. Finally, the output plate 62 and the upper substrate 411 are locked together with the quick clamp 65.

[0024] This invention allows for flexible switching between different machine heads, eliminating the need for repeated manufacturing of other parts of the leveling machine, thus saving manufacturing costs. It is also simple to operate and quick and practical to use.

[0025] It should be noted that, in addition to being detachably fixed to each other via the quick clamp 65, the output board 62 and the upper substrate 411 can also be detachably connected via screws or other detachable fixing methods. The left and right drive modules 30 can be other drive modules besides the cylinder 301.
