For processing of deformed and eccentric parts, the workpieces are generally fixed with a flower plate. Therefore, first of all, pay attention to the card. The claw and pressing plate shall not extend beyond the diameter of the disc, and it is better to install a shield. Secondly, pay attention to the counterweight of eccentric parts. It is important and appropriate. The clearance between the inner hole diameter of the counterweight and the screw diameter should be small. The rotating speed of the machine tool shall not be too high, so as to prevent the counterweight from moving outward under the centrifugal force during the rotation, colliding with the guide rail of the machine tool, breaking the screw and damaging the operator.
What safety requirements should the control system of machine tool equipment meet?
1. Easy to operate, reduce walking back and forth, avoid unnecessary bending and tiptoe.
2. The positioning is accurate and reliable to prevent misoperation due to slight vibration.
3. The movement direction of the operating parts and the movement direction of the operated parts of the machine tools shall meet the requirements, and shall be marked with simple symbols.
4. The necessary interlock mechanism shall be installed to prevent the uncoordinated action of the operating parts and the accidents caused by the uncoordinated operation of multiple persons.
5. The structure and arrangement position of handle, hand wheel and button shall meet the requirements. The start button shall be installed in the casing or equipped with a guard ring to prevent accidental touch. The handwheel and handle installed on the shaft rod will hurt people when rotating with the shaft during automatic feed, so the automatic release device shall be installed.
