Abstract
The utility model relates to a motor pressurizing system, which comprises an oil cylinder, a pedestal and a motor. The oil cylinder and the pedestal are rigidly connected, and one end of the piston rod of the oil cylinder is connected with the piston, and the other end is the screw rod connected with the nut shaft sleeve positioned in the pedestal. The oil cylinder cavities on two sides of the piston rod are respectively provided with an outlet, and one side of the nut shaft sleeve depends on the protruding edge, and the other side is limited with the inside of pedestal by the push stopping piece. The motor is fixed on the pedestal, whose shaft drives the nut shaft sleeve to rotate. The utility model has advantages that: the utility model increases the system working pressure for the different media like oil, liquid and gas in the oil cylinder through motor driving the piston, and the piston presses the medium in the oil cylinder cavity, thereby, the whole system has a simple structure and a small volume, high and sensitive control precision and high working efficiency and saves energy, but also can realize the alternative pressurizing of the double system.
Description
Technical field
The utility model relates to a kind of pressurization system, particularly relates to a kind of pressurization system that is used for the employing motor of injection machine.
Background technique
Existing pressurization system adopts mostly with the hydraulic pressure intensifier of piston area product moment as the supercharging principle, and therefore whole pressurization system volume is bigger, and control accuracy is low, sensitivity is low, energy consumption is higher, and can only realize the single system supercharging and can't realize the double system supercharging, so efficient is low.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and provide a kind of and can significantly reduce volume and motor pressurization system that can bidirectional booster.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
The motor pressurization system, comprise oil cylinder, bearing and motor, oil cylinder and bearing are rigidly connected, piston rod one end of oil cylinder connects piston, and the other end is a leading screw, and is connected with nut shaft cover in being fixed on bearing, in the oil cylinder chamber of piston rod two sides an outlet is arranged respectively, nut axle sleeve one side relies on its nib, opposite side spacing by thrust piece and bearing inside, and motor is fixed on the bearing, and its axle drives the rotation of nut axle sleeve.
Compared with prior art, advantage of the present utility model is: by the driven by motor piston, and by the medium in the piston extrusion oil cylinder chamber, thereby increase its system works pressure as oil, liquid, gas for in-oil cylinder various media, therefore whole system is simple in structure, volume is little, control accuracy is high and sensitive, high working efficiency and energy-conservation, and can realize that double system replaces supercharging.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Another embodiment's of this utility model of Fig. 2 structural representation.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the motor pressurization system, comprise oil cylinder 1, bearing 5 and motor 8, oil cylinder 1 and bearing 5 are rigidly connected, and piston rod 4 one ends of oil cylinder 1 connect piston 2, the other end is a leading screw, and is connected with nut axle sleeve 7 in being fixed on bearing 5, respectively have one to export 11 and 12 in the oil cylinder chamber of piston rod two sides, motor 8 is fixed on the bearing 5, itself and an end axial restraint of nut axle sleeve 7, nut axle sleeve 7 one sides rely on its nib, opposite side inner spacing with bearing 5 by thrust piece 6.
When motor 8 clockwise and anticlockwise are rotated, drive 7 rotations of nut axle sleeve, because nut axle sleeve 7 is subjected to the spacing of thrust piece 6, axle sleeve 7 can only rotate in bearing 5, and forces with the spiral piston rod 4 and the piston 2 thereof of its formation kinematic pair reciprocating.When piston 2 is moved to the left, improve (supercharging) with the working pressure of outlet 11 medium systems that link to each other, at this moment, be low pressure with the working pressure of 12 systems that link to each other of outlet; Vice versa, when piston 2 moves right, reduces with the working pressure of outlet 11 medium systems that link to each other, and at this moment, increases with the working pressure of outlet 12 systems that link to each other.Thus, oil cylinder two chambeies can realize that double system replaces supercharging.
7 on above-mentioned bearing 5 inner processes and nut axle sleeve link to each other by bearing 10, and to reduce friction, holding nut axle sleeve 7 improves the reliability and stability of work.
That above-mentioned motor 8 can be is servo, the frequency conversion AC and DC, synchronously, the motor of type such as permanent magnetism.
By seal ring 3 sealings, seal ring 3 sealings are arranged also between rotary-piston bar 4 and cylinder body between above-mentioned piston and cylinder body.
As shown in Figure 2, the motor 8 of motor pressurization system is fixedlyed connected with nut axle sleeve 7 by a pair of conjugation engaging member 9, and other is identical with last embodiment.
The motor 8 of above-mentioned pressurization system drives nut axle sleeve 7 by engaging member 9 and rotates.
Above-mentioned engaging member can be a pair of gear, sprocket wheel, synchronous band etc.
