Abstract
Disclosed is a spiral motor which includes a motor rotor and stator (2); a shaft (5) of the rotor is a guide screw and two symmetrical through-slots (8) are arranged on the shaft; an iron core (7) is screw-jointed with the shaft (5); a coil is arranged on the stator (2) which is hooped closely with a casing (1); one end of each of the four supporting keys (6) is welded on the protrusion of the casing (1), with the other end being embedded in the through-slots (8) of the shaft, bearing the casing on the shaft and sliding in the through-slots (8) of the shaft; one end of a sleeve (3) is welded on the iron core (7) with the other end being embedded with a rolling ball (4) which touches the inner wall of the casing (1). When the power is on, the spiral movement of the iron core (7) drives the rectilinear motion of the stator (2) on the shaft (5). The spiral motor integrates a platform and an electromotor into one body to simplify the lathe mechanism and save space.
Description
One, affiliated technical field
The utility model relate to a kind of can be on the axle of oneself motor, the especially device that can on the leading screw of lathe, move of straight reciprocating motion.
Two, background technology
Traditional lathe platform is mounted on the leading screw, and the rotation of driven by motor leading screw, thereby the straight reciprocating motion of implementation platform though such device is simple, are fallen behind, have taken a large amount of spaces.
Three, summary of the invention
For the not compactedness of the platform mobile device that solves existing lathe, a kind of main body of this practical proposition can be on axle the screw motor of linear reciprocating motion, this kind motor lumps together platform and motor body junction, leading screw then play conventional motors spool effect.Platform can be along with main body reciprocating motion on leading screw of screw motor.
The scheme that its technical problem that solves the utility model adopts is: rotor is connected with the leading screw spiral, shell supports keys by four and is embedded in two grooves on the leading screw, and stator is become one by the shell clamping, can realize like this when motor rotation, leading screw does not rotate, and main body is moving linearly on leading screw then.
The beneficial effects of the utility model are: platform and motor are combined in one, have simplified lathe mechanism, saved the space.
Four, description of drawings
Below in conjunction with accompanying drawing embodiment is described further:
Fig. 1 screw motor front view
Fig. 2 screw motor A-A profile
Among the figure:
1. motor housing
2. motor stator
3. sleeve
4. ball
5. spool (that is: leading screw)
6. support key
7. rotor
The axle on groove
Five, embodiment
A kind of screw motor (Fig. 1) comprising: rotor and stator (2), its rotor comprise iron core 7 and axle 5.The axle 5 of rotor is a rectangular teeth leading screw, also can be stepped tooth; And have the groove 8 of two symmetries on the axle.Iron core 7 (silicon steel sheet that is superimposed) is to be threaded with axle 5.Sleeve one end is welded on unshakable in one's determination 7, and ball 4 in other end embedding, and ball 4 contacts with shell 1 inwall, and ball plays the effect that keeps shell and rotor not to bump against with sleeve.Coil is on stator 2, and stator and shell 1 lock ring are together.Four are supported the ledge that key one ends are welded on shell 1, and the other end is embedded in 8 li of the grooves of axle, plays shell in the axle upper support, and can slide in the groove of axle.
When rotor rotates in motor since with the spiral interconnect function of axle 5, and axle 5 is fixed and can not rotates, so iron core 7 is for the helical movement on axle 5, the effect by sleeve 3 and ball 4 simultaneously promotes shell 1 and stator 2 moving linearly on axle.In this process, support key 6 and in groove 8, slide all the time, the rectilinear motion of the screw of iron core 7 and stator 2 is independent mutually, is independent of each other.
After the energising, the screw of iron core 7 drives stator 2 moving linearly on axle 5.
Claims (1)
1. screw motor, comprising: rotor and stator (2) is characterized in that: the axle of rotor (5) is a rhizoid thick stick, and has the groove (8) of two symmetries on the axle, iron core (7) is to be threaded with spool (5); Coil on stator (2), stator and shell (1) lock ring together, four are supported the ledge that key (6) one ends are welded on shell (1), the other end is embedded in groove (8) lining of axle, plays shell in the axle upper support, and can slide in groove (8) lining of axle; Sleeve (3) one ends are welded on the iron core (7), and ball (4) in other end embedding, and ball (4) contacts with shell (1) inwall, and after the energising, the screw of iron core (7) drives stator (2) and goes up moving linearly at axle (5).
