Abstract
The utility model relates to a piston pump, which is arranged at a machine tool to spray chilled water on the worked up workpiece, comprising a pump body, an intake valve, a discharge valve, piston-rod rolling wheels and cams which are arranged on the screw rod or polished rod of the machine tool. The utility model is no need of additional dynamic force, the production cost and energy resource are saved, and the repairing and handing are convenient.
Description
A kind of machine tooling workpiece process that is used for carries piston pump, especially lathe and the milling machine of cooling water for workpiece and cutter.
Be equipped with electric-motor pump on the lathe at present cooling water is provided, to guarantee the smooth processing of workpiece.In the summer of sweltering heat, motor works long hours, and easily produces high temperature, causes motor to damage, and produces thereby influence is normal.The electric-motor pump cost is higher in addition, also power consumption.
The purpose of this utility model designs a kind of piston pump exactly, does not need to establish in addition motor, and the power that is transmitted by screw mandrel or polished rod when working by lathe drives, thereby saves lathe cost and workpiece processing cost, energy savings.
The technical solution of the utility model is such: by the pump housing, be located at water intaking valve and outlet valve, piston rod on the pump housing, be located at the roller of piston rod end, the cam that is located at lathe screw mandrel or polished rod end is formed, the pump housing is fixed on the bed piece, establishes a back-moving spring on the piston rod to guarantee that roller contacts all the time with cam.Outlet valve links to each other with delivery hose, and water intaking valve is logical by flexible pipe and water.
On the pump housing, establish a limit screw,, piston rod is separated the limit screw pupil tightly on piston rod with cam so that when not using pump.At this moment, though lathe work, piston pump is not worked.
Operation principle of the present utility model is such:
When using the machine tooling workpiece, rotation along with screw mandrel or polished rod, dress cam thereon also rotates, and moves back and forth thereby drive piston rod, when cam goes to minimum point by peak, piston rod is under the elastic force effect of spring, shrink back, finish the suction stroke, at this moment, outlet valve is closed, and water intaking valve is opened.When cam went to peak by minimum point, piston rod was finished the setting-out stroke, and this moment, water intaking valve was closed, and outlet valve is opened.Piston rod ceaselessly moves back and forth like this, and reaches the effect of suction setting-out, thereby is punched on workpiece, the cutter head with guaranteeing continuous cooling water.When not needing cooling water, only need push inward piston rod and enter at the end, screw limit screw then.Cam thoroughly separates with roller, gets final product.
Technical characterstic of the present utility model and result of use:
1, simple in structure, convenient by dress;
2, volume is little, and is in light weight, and noise is low;
3, because its power directly by obtaining on lathe screw mandrel or the polished rod, does not need to add motor, thereby saved electric power, also saved production cost.
4, entire equipment all is mechanical, so maintenance, easy maintenance is and fragile.
Below in conjunction with accompanying drawing the utility model is done further narration:
Accompanying drawing is a structural representation of the present utility model, and 1 is outlet valve among the figure, the 2nd, and water intaking valve, the 3rd, trip bolt, the 4th, the pump housing, the 5th, piston rod, the 6th, roller, the 7th, cam, the 8th, lathe screw mandrel, the 9th, limit screw.
As shown in the figure: when lathe was worked, screw mandrel rotated, and cam also rotates thereupon, and the reciprocating motion of driving rolls drive piston rod, and water is drawn into, gets, thereby provided cooling water continuously to workpiece to be machined.When not needing cooling water, piston rod is advanced to the end, screws limit screw, roller thoroughly separates with cam, at this moment, though lathe work, the piston air pump inoperative.
Claims (2)
1, a kind of on lathe cutting workpiece and cutter the piston pump of cooling water is provided continuously, it is fixed on the bed piece, it is characterized in that piston body is provided with a water intaking valve, an outlet valve, tailpiece of the piston rod is established a roller, this roller contacts with the cam that is located at lathe screw mandrel or polished rod end, and piston rod is provided with a back-moving spring.
2, the piston pump of narrating according to claim 1 is characterized in that the pump housing is provided with the limit screw of a latching ram bar.
