Special Machine for Servo Gate Valve The hydraulic power station portion of the valve can be placed as a module behind the machine tool. The hydraulic tailstock system can be added to make it another operable module, sharing the same hydraulic power system, when the tailstock is required for mass processing.

In processing, when the program runs to the need for variable speed state, the CNC system first sends a stop signal, and then the program sends a control signal to make the hydraulic pump start oil supply, while the solenoid valve of the hydraulic system suction according to the control signal, to supply oil to the variable speed cylinder, so that the piston rod extends or returns, pushing the fork to make the gear change, when the gear moves in place, The CAM touches the microswitch, the feedback signal to the CNC system, then the variable speed ends, and the program continues to run downwards to process the workpiece.

Special Machine for Servo Gate Valve Spindle transmission module is installed on the spindle box, which is composed of support, oil cylinder and tubing, micro-switch and so on. The length and width of the support are the same as that of the top of the headstock. The whole spindle speed change module is installed on the four screw holes originally used to install the cover plate on the headstock, and the positioning pin holes are added to position the module. The middle of the support is supported by a partition board, and the variable speed oil cylinder is fixed on the partition board, and is located above the gear shaft to control the slip, and the guide shaft is coaxial; The cylinder piston rod is located in the guide shaft, and is connected with the speed shifting fork through the pin shaft; The shifting fork is set on the guide shaft and can move back and forth along the guide shaft under the drive of the piston rod; The guide shaft is hollow and has a guide groove, so that the piston rod and the variable speed fork are connected, and the guide shaft is fixed on the support by the pin shaft; The two gear shifting forks have downward vertical structure and are respectively stuck in the transmission groove of the corresponding sliding gear.

When the oil cylinder supplies oil, the piston rod drives the sliding fork to move the sliding gear through the pin shaft, so that the gear is engaged in the gear transmission. After the gear is in place, the convex block on the shifting fork touches the micro-switch on the cover plate and sends out the gear in place signal, which is the end of the gear transmission.
