step 5, adjusting the movable blocks through the sliding table cylinder to enable the distance between the movable blocks to be reduced, further enabling the distance between the two movable blocks to achieve an expected effect, further achieving an effect of clamping an engine cylinder cover, enabling the engine cylinder cover not to deviate in the pressing process of the device, further ensuring the accuracy in the pressing process, and completing the pressing process;
step 6, after the engine cylinder cover pressing work is finished, the transport table drives the engine cylinder cover to start transport, the moving engine cylinder cover is conveyed to a detection machine, the detection machine starts to detect the pressed engine cylinder cover, and therefore the pressed engine cylinder cover can reach an expected standard and the detection work is finished;
and 7, continuously rotating the transport table to drive the engine cylinder cover to the position of the transporter, starting the transporter to work, transporting the engine cylinder cover to the transport belt by the moving transporter, and driving the engine cylinder cover to start transporting by the moving transport belt to finish the work.
