Background technique
Electro-hydraulic proportional valve is that in valve, proportion electro-magnet produces corresponding actions according to the voltage signal of input, makes operating valve spool produce displacement, port size change and complete the pressure proportional with input voltage with this, element that flow exports.Spool travel also can feed back with the form of machinery, hydraulic pressure or electricity.Use electric and computer-controlled various electrohydraulic system because electro-hydraulic proportional valve has form wide variety, easily composition, install and use flexibly and many-sided advantage such as contamination resistance is strong, therefore application is widened day by day.
In recent years the plug-in type Proportional valve of development & production and proportional multi-way valve fully take into account the handling characteristics of engineering machinery, have the functions such as pilot control, load-transducing and pressure compensation.Its lifting of appearance to mobile hydraulic machinery overall technology level is significant.Particularly in automatically controlled pilot operated, Wireless remote control and wired remote control operation etc., present its good application prospect.
Existing electro-hydraulic proportional multi-way valve adopts analogue signal control accuracy not high, but higher to the requirement of oil product, and its internal structure is complicated, and comprise sensitivity and precise part, difficulty of processing is high, and price is high.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of servo electric machine type numerical control multiplex valve, and adopt digital signal, control accuracy is high, and structure is simple and cost is lower, also not high to the requirement of oil product, reduces costs.
To achieve these goals, the technical solution adopted in the utility model is: a kind of servo electric machine type numerical control multiplex valve, comprise housing and be positioned at the actuating motor of housing, the output shaft of actuating motor is connected with leading screw, leading screw is provided with the feed screw nut with its screw-thread fit, one end of push rod is connected with feed screw nut, and the other end is connected with multi-way valve, be provided with guide groove in push rod, described feed screw nut is provided with the pin matched with guide groove flute profile width dimensions.
Actuating motor is connected with leading screw by coupling.
Leading screw arranges guide rod, and guide rod is connected with feed screw nut by bearing.
Feed screw nut and pin are structure as a whole.
The utility model is on the basis of common multi-way valve, this device a set of is like this installed, control the distance of feed screw nut walking by electric machine rotation angle thus realize continuously proportional control, according to actual conditions change control valve opening direction, opening amount, realize the action of a series of servo-actuated change controlled continuously, complete the control to multi-way valve delivery pressure and flow, this structure is simple and cost is lower, not high to the requirement of oil product yet, identical with the oil product that common multi-way valve uses just passable, reduce cost of production, adopt digital signal, control accuracy is high.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, this servo electric machine type numerical control multiplex valve, comprise housing 1 and be positioned at the actuating motor 2 of housing 1, the output shaft of actuating motor 2 is connected with leading screw 3, leading screw 3 is provided with the feed screw nut 4 with its screw-thread fit, one end of push rod 5 is connected with feed screw nut 4, and the other end is connected with multi-way valve 10, be provided with guide groove 7 in push rod 5, described feed screw nut 4 is provided with the pin 6 matched with guide groove 7 flute profile width dimensions.
Actuating motor 2 is connected with leading screw 3 by coupling 11.
Leading screw 3 arranges guide rod 8, and guide rod 8 is connected with feed screw nut 4 by bearing 9, and guide rod 8 plays leading role, the rotation of feed screw nut 4 can be prevented, improve validity, bearing 9 transfers the relative sliding friction between guide rod 8 and feed screw nut 4 to rolling friction, reduces energy consumption.
Feed screw nut 4 and pin 6 are structure as a whole, and as preferred version of the present utility model, described feed screw nut 4 is structure as a whole with pin 6, be convenient to processing, and not fragile, long service life, certain feed screw nut 4 and pin 6 also can be separate, by Placements such as screw threads, link together, but this mode, there will be the phenomenons such as loosening after using a period of time, need often to look into repair, and change inconvenient.
Working principle: multi-way valve 10 is in closed condition, now push rod 5 is in vertical state, open actuating motor 2, leading screw 3 rotates, feed screw nut 4 straight line motion, feed screw nut 4 drives push rod 5 to move by pin 6, push rod 5 drives the spool of multi-way valve 10 to move, multi-way valve 10 is opened, the distance of spool movement is controlled by the rotation number of turns of actuating motor 2, and then control the size of flow, controlled the displacement distance of multi-way valve 10 spool by the rotation number of turns controlling actuating motor 2, and then control the size of multi-way valve 10 valve port unlatching; When needs are closed, actuating motor 2 reverses, and feed screw nut 4 gets back to initial position fast and push rod 5 is in vertical position, and multi-way valve 10 gets back to meta, multi-way valve 10 is closed, above drive leading screw 3 by actuating motor 2 rotate through mechanism to realize the control of multi-way valve pressure and flow.
The above is only preferred embodiments of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
