The first end of the connecting rod is connected with a pressing shaft through a rivet, and the pressing shaft extends out of the mounting plate. Then, a spring is sleeved on the extended pressing shaft, the spring is tightly pressed by a pressing plate, and a bolt, namely an ejector rod, is screwed in by aligning with a threaded hole on the pressing shaft, so that the pressing shaft and the pressing plate are fixed. The second end of the connecting rod extends out of the side plate, the pressing block is adhered to the baffle through an adhesive, and the pressing block adhered to the baffle is fixed to the second end of the connecting rod through a bolt. Meanwhile, the pressure sensor is adhered to the mounting plate. Thus, the link fixing mechanism is mounted to the machine tool cooling unit.

So set up, insert the filter screen and block the back in the recess, because the action of gravity, the filter screen pushes down simultaneously on the ejector pin of the first end of connecting rod, make the connecting rod second end to the direction removal that is close to the filter screen, the baffle will support on the filter screen lateral part like this, thereby compress tightly the filter screen, the restriction filter screen removes, the fixed effect of filter screen has further been strengthened, even the unit vibrations, the filter screen also can not rock easily again, the fixed reliability of filter screen has been improved, the reliability of equipment has been promoted simultaneously, the problem that leads to the filter screen to drop because of unit vibrations or artificial mistake in having solved among the prior art at the unit operation in-process. When the filter screen is dismantled, because the effect of spring, can take out the filter screen more easily, realize that the convenient dismouting of filter screen is reliably fixed. Meanwhile, the pressure sensor can prevent the spring from losing efficacy due to overlarge pressure, and can prompt maintenance reminding when the filter screen accumulates dust to be overweight, so that the filter screen maintenance detection is realized, and the use reliability of the unit is ensured.
