Abstract
The utility model relates to a motor device of screw rod type rotor, which comprises a motor shell, a motor back cover and a rotor winding. The utility model also comprises a screw rod assembly, a screw rod nut engaged with the screw rod assembly and capable of rotating relative to the screw rod assembly which is arranged in the motor shell and a slide assisting device sleeved on the screw rod nut, and the rotor winding is winded on the screw rod nut. The utility model is compact in structure, which decreases transmission links, improves transmission efficiency and is convenient for control. The utility model is also high in control procession, fast in reaction, and easy for employment, which decreases transmission link and is convenient for installation.
Description
Technical field
The utility model relates to a kind of motor; relate in particular to a kind of electronic device of leading screw type rotor, this motor can be used for plastic injection molding equipment, die cast metal former, rubber pattern press forming device, forcing press or other to be had in the fields such as driving of the equipment of clamping liftout attachment and numerical control travelling table.
Background technology
Existing is the transmission device that drives power with the motor, all be rotatablely moving of motor to be passed to lead screw pair by belt wheel transmission or gear drive, by lead screw pair this being rotatablely moved to convert to drives moving component behind the rectilinear motion again and advances or retreat, and finishes the forward or the inverted running of moving component.The weak point of the transmission device of this type is:
(1), the transmission of power is through conversion several times, energy loss is big, transmission efficiency is low.
(2), certain spacing must be arranged between the active of belt wheel transmission or gear drive and the driven pulley, mechanism size is big, the space is nervous.
(1), more transmission link causes and is movably hinged manyly that kinematic accuracy and rigidity all are affected.
The utility model content
The purpose of this utility model provides a kind of compact conformation, reduces driving-chain, improves transmission efficiency, is convenient to control, and control precision is than higher, and response ratio is very fast, is easy to use, and reduces transmission link, is convenient to install the electronic device of leading screw type rotor.
In order to achieve the above object, the utility model is achieved in that it is a kind of electronic device of leading screw type rotor, comprises electric machine casing, is located at rotor, motor bonnet and rotor winding in the electric machine casing; It is characterized in that: also comprise lead screw pair, rotor is for that be meshed with lead screw pair and feed screw nut that can rotate to it and be set in the sliding device that helps on the feed screw nut; The rotor winding is on feed screw nut.
Described radial bearing and the taper roll bearing that helps sliding device to comprise to be set in the thrust bearing of rotor one end and be set in the rotor other end.
Described lead screw pair is common lead screw pair or ball screw assembly.
The utility model advantage compared with prior art is: it is a kind of extraordinary motor that function in feed screw nut and the lead screw pair is united two into one, to rotatablely move by lead screw pair and to be converted to rectilinear motion with feed screw nut engagement, input electrical signal by the control motor can be controlled torque, rotating speed, rotation displacement, the rotation direction of feed screw nut and lead screw pair exactly, and this type of device has following distinguishing feature:
1) compact conformation, especially the feed screw nut of rotor portion and lead screw pair structure can reduce driving-chain, improve transmission efficiency.
2) be convenient to control, can directly be reflected on the moving component by the control of external signal motor stator and rotor, thus control precision than higher, response ratio is very fast.
3) be easy to use, owing to reduced transmission link,, be convenient to install control etc. so use more conveniently.

Embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, it is a kind of electronic device of leading screw type rotor, comprise electric machine casing 8, motor bonnet 5, rotor winding 7, lead screw pair 9, be meshed with lead screw pair and can rotate to it be located at the feed screw nut 6 in the electric machine casing and be set in the sliding device that helps on the feed screw nut; Rotor winding 7 is on feed screw nut.The radial bearing 12 and the taper roll bearing 10 that help sliding device to comprise to be set in the thrust bearing 11 of feed screw nut one end and be set in the feed screw nut other end in the present embodiment.Lead screw pair 9 is common lead screw pair or ball screw assembly.
During use, shown in Fig. 2,3, electric machine casing 8 is fixed on the template 3, feed screw nut 6 endoporus are processed into the screw channel section engagement of screw and lead screw pair 9, and the other end of lead screw pair and thimble guide plate 1 are affixed; Guide rod 2 one ends are fixed on the template 3, and the Kong Bingwei ejector retainner plate slippage that the other end passes on the ejector retainner plate provides guiding; Between thimble guide plate and guide rod slide relative face the dress use wear part, can make the thimble guide plate along guide rod shaft to smooth and easy slippage; Thimble rod 4 one ends are fixed on the thimble guide plate and can play motion with one.
During work, when feed screw nut 6 rotated by counter clockwise direction (as Fig. 1), inner spiral groove on the feed screw nut and lead screw pair external spiral rib were meshing with each other, and make the relative template of lead screw pair to the right-hand member rectilinear motion, drive the thimble guide plate along guide rod slippage to the right, finish thimble and eject action.
When feed screw nut rotates in the direction of the clock, make the relative template of lead screw pair to the left end rectilinear motion, drive the thimble guide plate along guide rod slippage left, finish thimble and return action.
