Abstract
The utility model discloses a numerical control hydraulic power device system which includes a PLC or a computer; a servo motor is connected with the PLC or the computer; an input gear is engaged with the output shaft of the servo motor; a small oil cylinder is engaged with the input gear through a rack on a piston rod; a big oil cylinder provided with the piston rod is connected with the small oil cylinder through an oil pipe; and the output gear is engaged with the rack on the piston rod in the big oil cylinder. The numerical control hydraulic power device system controls the servo motor through the PLC or the computer; the servo motor drives the gear to drive the rack of the oil cylinder; a force is amplified by a hydraulic system and is changed into corner control through the gear and the rack to reach the goal of enlarging output torques. The numerical control hydraulic power device system has the advantages of small cost and solves the problem of non-large torque servo motor currently.
Description
Technical field
The utility model relates to a kind of numerical control hydraulic power unit, particularly is meant a kind of numerical control hydraulic power system, is used in the occasion that machinery etc. needs high pulling torque.
Background technique
At present, Numeric Control Technology is widely used, but actuating motor mostly is low moment of torsion, owing to there is not the high pulling torque actuating motor, if employing mechanical transmission, then volume is bigger again, therefore, how to design a kind of reasonable in design, numerical control hydraulic power unit applied widely, to be applied in the heavy mechanical equipment, be present urgent problem, have that the utility model arises at the historic moment based on this.
The model utility content
At above-mentioned technical problem to be solved, main purpose of the present utility model provides a kind of reasonable in design, a kind of numerical control hydraulic power unit system applied widely.
The technological scheme that the utility model is taked is as follows, a kind of numerical control hydraulic power unit system of the present utility model, comprise PLC or computer, actuating motor links to each other with PLC or computer, the input gear is meshed with the output shaft of actuating motor, small oil tank is meshed with the input gear by the tooth bar on the piston rod, and the large tank of band piston rod links to each other by oil pipe with small oil tank, and the tooth bar on the interior piston rod of output gear and large tank is meshed.
Working principle of the present utility model is as follows: during work, by PLC or computer-controlled servo motor work, the power of actuating motor passes to the input gear by output shaft, and by the tooth bar on the piston rod, the piston rod movement of interlock small oil tank, because large tank links to each other by oil pipe with small oil tank, Pascal's theorem according to equation, on large tank, can obtain the power of an amplification, thereby the piston rod movement on the drive large tank, it is holding to become corner by output gear again, thereby reaches the purpose that increases output torque.
The beneficial effects of the utility model are as follows: a kind of numerical control hydraulic power unit system of the present utility model, by adopting less actuating motor, produce bigger output torque, and compared with prior art have the following advantages:
1,, produces bigger output torque with less actuating motor;
2, cost is little.
Below in conjunction with the drawings and specific embodiments the utility model is further described in detail, following examples are to explanation of the present utility model but the utility model is not limited to following examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of numerical control hydraulic power unit system of the present utility model, comprise PLC or computer 1, actuating motor 2 links to each other with PLC or computer 1, input gear 3 is meshed with the output shaft of actuating motor 2, small oil tank 4 is meshed with input gear 3 by the tooth bar on the piston rod 7, and the large tank 5 of band piston rod 9 links to each other by oil pipe 8 with small oil tank 4, and the tooth bar on the interior piston rod 9 of output gear 6 and large tank 5 is meshed.
Working principle of the present utility model is as follows: during work, by PLC or computer 1 actuating motor 3 input angular signals, 2 work of control actuating motor, the power of actuating motor 2 passes to input gear 3 by output shaft, and by the tooth bar on the piston rod 7, piston rod 7 motions of interlock small oil tank 4, because large tank 5 links to each other by oil pipe 8 with small oil tank 4, Pascal's theorem according to equation, on large tank 5, can obtain the power of an amplification, thereby drive piston rod 7 motions on the large tank 5, become corner control by output gear 6 again, thereby reach the purpose that increases output torque.
