In order to solve the problems of the technologies described above, the technical solution of the utility model provides a kind of plunger pump cylinder body and the valve plate spherical grinds equipment, it is characterized in that: comprise the cylinder of being located at the valve plate top, the valve plate driving mechanism of being located at cylinder interior is connected with valve plate by elastic mechanism, and the valve plate drive motors is located at valve plate driving mechanism top; The cylinder body that is connected with valve plate is located on the adjustable driving pedestal of diameter of chuck by frock, and the cylinder body drive motors is connected with the driving pedestal; Can valve plate be that the eccentric stiffener that supporting surface up and down reciprocatingly swings is connected with the valve plate driving mechanism with the contact-making surface of cylinder body.
Preferably, the contact-making surface that is installed of described valve plate is the POM material.
Preferably, the contact-making surface of described valve plate and cylinder body is provided with the lapping liquid by the instillation mode of procedure auto-control.
Preferably, the amplitude of fluctuation of described eccentric stiffener is ± 20 °.
Preferably, described cylinder is provided with cylinder valve, and the cylinder below is provided with position limiting structure.
Preferably, be provided with spring in the described elastic mechanism.
When a kind of plunger pump cylinder body that the utility model provides and valve plate spherical grind armament-related work, the cylinder body drive motors drives the cylinder body rotation, the valve plate drive motors drives the valve plate rotation by elastic mechanism, and eccentric stiffener drives valve plate by the eccentric stiffener drive motors and swings.After machining, valve plate and frock will rise with workpiece loading and unloading automatically.Device selects ordinary three-phase synchronous to drag, and frequency converter timing has successfully been realized the smooth transition of starting, parking, has satisfied the technological requirement of grinding; The machine is carried out timing control to cylinder body drive motors, valve plate drive motors, eccentric stiffener drive motors respectively by PLC and three counters.
Compared to existing technology, the utlity model has following beneficial effect:
(1) can regulate the pressure of grinding by cylinder, maximum grinding pressure can be used for the workpiece of diameter 200mm;
(2) the eccentric stiffener amplitude of oscillation is adjustable, and the full swing adjustable angle is to ± 20 °;
(3) be used for the diameter of chuck of driving pedestal of stationary housing anchor clamps, deck adjustable, clamping range is wide, cylinder body that can the clamping different size;
(4) adopt PLC and three counters can control timing and grind high efficiency;
(5) valve plate has independent rotary actuation in process.Under original state, when valve plate center line and cylinder center line were can not be complete overlapping, underlapped zone can be polished very even in the effect of mutually rotation.
The device that the utility model provides has overcome the deficiencies in the prior art, by driving and the Based Intelligent Control timing of cylinder body and the independent rotation of valve plate configuration are ground, in guaranteed performance higher operating efficiency is arranged simultaneously reliably, and rational in infrastructure, applied widely.
