Education Lathe hydraulic power station how much do you know?
In the educational lathe, the hydraulic power station section can be placed as a module behind the machine. In the need for tailstock top of the large quantities of processing, can be installed hydraulic tailstock top system, making it another operable module, sharing the same hydraulic power system.
In the process, when the program is running to the need to change the state, the CNC system first issued a parking signal, and then issued a control signal to start the hydraulic pump fuel supply, while the hydraulic system solenoid valve according to the control signal to pull, to the variable speed cylinder for Oil, so that the piston rod protruding or retracted, pushing the fork to make the gears change, when the gear moves in place, the cam touches the micro switch, the feedback signal to the numerical control system, then the speed end, the program continues to run down to carry out the workpiece.
Spindle speed module installed in the spindle box, which by the bracket, cylinder and tubing, micro switch and other components. The length of the bracket is the same as that of the spindle box. The spindle speed module is installed on the four screw holes used to install the cover plate on the spindle box, and the positioning pin hole is used for the positioning of the module. The middle part of the bracket is supported by the partition plate, the variable speed cylinder is fixed on the partition plate and is located above the gear shaft to be controlled slip, and is coaxial with the guide shaft; the cylinder piston rod is located in the guide shaft and is connected with the variable speed fork; The shift fork is mounted on the guide shaft and can be moved back and forth along the guide shaft driven by the piston rod. The guide shaft is hollow and has a guide groove so that the piston rod is connected with the shift fork. The guide shaft is fixed to the bracket by the pin ; Two gear shift fork are down vertical structure, respectively, in the corresponding sliding gear shift groove.
The piston rod through the pin to drive the slip fork to move the sliding gear, the gears for variable speed meshing, gear in place by the fork on the slider on the cover of the micro switch on the cover, the issue of gear in place Signal, then the end of the variable.
