Abstract
The utility model discloses a clamp for machining a variable head of a plunger pump. The clamp comprises a horizontal main shaft body, a longitudinal core shaft and a cone pine, wherein the longitudinal core shaft is arranged on the horizontal main shaft body and can be divided into an upper section and a lower section by the horizontal main shaft body; the upper and lower parts of the variable head of the plunger pump are respectively sleeved on the upper and lower sections of the longitudinal core shaft and are locked by blots; the cone pin is inserted from the side surface of the horizontal main shaft body so as to clamp the horizontal main shaft body and the longitudinal core shaft. The clamp can be used for stably fixing the variable head of the plunger pump, and is simple in structure, and convenient to install and disassemble.
Description
Technical field
The utility model relates to a kind of fixture, relates in particular to a kind of plunger displacement pump variable head fixture for processing.
Background technology
Hydraulic pump is the dynamical element of hydraulic system, and its effect is the mechanical energy of prime mover to be converted to the pressure energy of liquid, refers to the oil pump in hydraulic system, and it provides power to whole hydraulic system.The version of hydraulic pump generally has gear pump, vane pump and plunger displacement pump.
The oil through of the pressure oil of Variable plunger pump in the pump housing, pump case variable shell is by the cavity of resorption of check valve entering variable housing, when pull bar moves downward, the promotion servo piston moves down, the upper valve port of servo valve is opened, the oil through entering variable housing epicoele of the pressure oil of variable shell cavity of resorption in the variable piston, due to upper cavity area greater than cavity of resorption, the hydraulic coupling pushing piston moves downward, driving bearing pin makes the variable head around the 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, and 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, the variable head changes to the negative bias angular direction, and commutation, the oil inlet and outlet conversion of pump are given birth in the liquid miscarriage.
As shown in Figure 1, this plunger displacement pump variable head 10 is comprised of upper and lower two parts a kind of plunger displacement pump variable head of Variable plunger pump, and upper and lower two parts are provided with vertical endoporus 11; At present, when this plunger displacement pump variable head 10 is adopted the grinding machine processing excircles, be to select the plain clamp clamping, clamping is firm not.
The utility model content
For the problems referred to above, the utility model provides a kind of plunger displacement pump variable head fixture for processing, to solve plunger displacement pump variable head-clamp of the prior art, holds firm not problem.
To achieve these goals, the technical solution of the utility model is as follows:
Plunger displacement pump variable head fixture for processing, it is characterized in that, comprise horizontal main shaft, vertical mandrel and taper pin, described vertical mandrel is arranged on horizontal main shaft, and by horizontal main shaft, being separated into upper and lower two sections, upper and lower two parts of plunger displacement pump variable head are set in upper and lower section of vertical mandrel, and pass through bolt-locking, taper pin inserts from the side of horizontal main shaft, blocks horizontal main shaft and vertical mandrel.
In the utility model, described horizontal main shaft and vertical mandrel are the integral type structure.
