Description
Technical field
The utility model relates to a kind of variable head mill internal clamp.
Background technology
The oil through of pressure oil in the pump housing, pump case variable shell of Variable plunger pump passes through the cavity of resorption of check valve entering variable housing, when pull bar moves downward, promotion servo piston moves down, the upper valve port of servo valve is opened, the oil through entering variable housing epicoele of pressure oil in variable piston of variable shell cavity of resorption, because upper cavity area is greater than cavity of resorption, hydraulic coupling promotes piston and moves downward, bearing pin is driven to make variable head around steel ball central rotation, change the inclination angle (increase) of variable head, the flow of plunger displacement pump increases thereupon.Otherwise pull bar moves upward, the inclination angle of variable head changes round about, and the flow of pump also changes thereupon.When angle of inclination fades to after zero, then variable head is to the change of negative bias angular direction, the raw commutation of liquid miscarriage, the oil inlet and outlet conversion of pump.
Plunger displacement pump variable head is the inner body of plunger displacement pump, to its technical requirement is: Φ 40D after general assembly, is not more than 0.05 of original precision with the circular runout of machine tool chief axis.The fixture that existing plunger displacement pump variable head adopts when grinding endoporus is plain clamp, reaches this requirement more difficult, therefore, needs a kind of special fixture being exclusively used in plunger displacement pump variable head mill endoporus.
