Equipment usage conditions
Main equipment composition
The machine is equipped with spindle box and hydraulic clamping mechanism, cylinder support mechanism, piston rod V-shaped bracket lifting mechanism, cylinder flange cover tightening mechanism, piston rod pushing back mechanism, electrical system and hydraulic system.
The base is welded with a square tube and a plate, and the plane is processed on the base as the installation reference surface to install the linear guide rail. After the bed is welded, heat treatment and timely treatment are carried out to eliminate the stress of the bed and maintain high precision after long-term use. The bed load can bear more than 500kg.
Spindle box and hydraulic clamping mechanism
It consists of a servo rotating main shaft, a hydraulic cylinder synchronous clamping mechanism and a bed head advance and retreat mechanism.
The rotating main shaft is driven by a servo rotating motor, and the gear is reduced to drive the main shaft to rotate. The gear is assembled with anti-backlash gears without rotation deviation. The main shaft adopts a rotary joint mechanism to deliver hydraulic oil to the front clamping cylinder.
The main shaft advance and retreat mechanism is driven by an AC motor, and the head part is moved back and forth to the appropriate position through the lead screw, and can be locked to achieve the purpose of adjustment.
Cylinder support mechanism
Equipped with 2 cylinder barrel brackets. The brackets are supported by rubber rollers, guided by guide posts, and the height can be adjusted up and down by the hand wheel. Pneumatic lifting mechanism, holding up and receiving material when loading, and falling down before work after positioning, realizing stable and reliable rotation of the workpiece.
Piston rod V-shaped bracket lifting mechanism
The mechanism is installed on the bed rail. The piston rod is supported by two V-shaped rubber wheels. The piston rod can roll forward and backward. The two brackets are installed on the up and down moving frame, and the distance is adjustable to adapt to the length of the workpiece. The moving bracket is guided by the front and rear wire gauges, and is driven by the oil cylinder to realize the height change of the V-shaped pallet.
Cylinder flange cover tightening mechanism
The torque of the torque machine is 1500kgf-m, and a torque wrench is installed at the output end to clamp the cylinder for work. The torque wrench has two modes: slot and hole.
The torsion mechanism is installed on the sliding frame, respectively guided by the guide rails to quickly approach the workpiece and insert it into the card slot for work. Under the control of the program, the end cover is automatically tightened.
Piston rod pushing mechanism
Driven by the hydraulic motor and the chain from the side, the mechanism pushes the piston rod back into the cylinder along the guide rail to complete the final process of installing the cylinder.
Hydraulic pressure station
The host adopts the OMRON PLC imported from Japan as the control core, and the execution system of the control welding procedures has good stability, simple structure and easy maintenance.
Control panel can move along the guide rail to adapt to different length of operation.
The tightening torque of the torque machine can be individually controlled on the control panel.
