Description

A kind of motor apparatus of rotatable wiring

Technical field

The present invention relates to motor apparatus field, specially a kind of motor apparatus of rotatable wiring.

Background technology

In some motor driving fields, generally require to use external rotor electric machine, its can floor space realize spy smallly Determine purpose transmission driving purpose.Some existing devices can be by using will simplify power supply mode around being mounted on stator.But It is that this mode has the shortcomings that winding space is limited so as to influenceing electric efficiency and radiating effect is poor.It is located at for winding outer Powered in the power supply of motor on rotor, some existing devices using the stator by center with rotor rotary electrical contact Pattern.This mode easily causes friction to cause loose contact and need periodic maintenance in power supply process.One In the case that a little motor rotational steps are little, such as servomotor, the side that direct wiring is powered can be used to this rotor Formula, but this easily causes the excessive twist ties of circuit to cause line impairment and be difficult to restorability.

The content of the invention

It is of the prior art for overcoming it is an object of the invention to provide a kind of motor apparatus of rotatable wiring is planted Drawbacks described above.

According to the motor apparatus of the rotatable wiring of the present invention, including pedestal and outer turn on the pedestal There is cam-type connecting part at sub-motor, the left part of the rotor of the motor, be separately directed through with for many electric wires, institute Stating cam-type connecting part, the pressure-producing part with being fixedly mounted on the pedestal rotatably connects by two connected slide bars Connect, circuit reverse plate is slidably supported with two slide bars, many electric wires are passing through the circuit from the motor It can mutually twist and be electrically connected with the binding post on the pressure-producing part after reverse plate, be set in the pressure-producing part Have and passed the pressure-producing part by two expansion links of spring loaded piston piece and the piston piece and turned round with the circuit Turntable rotation formula is connected, wherein, the both sides of the cam-type connecting part are respectively symmetrically provided with and can slided in the pedestal Two dynamic split fix framves, each split fix, which is set up, is equipped with multiple positioning protrusions, and the circuit reverse plate is described Revolved under the pushing of piston piece with being located at the left side plan that on described two split fix framves and two relative positioning are protruded respectively Rotatable engagement, the cam-type connecting part for each revolution can open on described two split fix frame tops once, described Under the pushing of piston piece the circuit reverse plate can stepping to the right and be bonded on the right side two in described two split fix framves Upper relative positioning protrusion, so that the wire twist segment length between the circuit reverse plate and the pressure-producing part increases Plus；Counter is installed, the right part of the rotor of the motor is provided with and can counted by described in the inwall of the pedestal right-hand member The detected body of device detection, so as to the rotation number of turns for the rotor for accurately learning the motor.

In the device of the present invention, the distance for being twisted or being twisted together due to motor circuit can be according to the rotating cycle of motor And step-by-step movement is adjusted, therefore, when motor turns to be in low rotating cycle, the length that its electrical wiring twists is shorter, and this can The kink position of control circuit makes it since apart from motor remote position and gradually developed to the position close to motor, thus Avoid circuit kink from starting to betide at the position of motor or certain specific location, passed by so as to avoid result in local line Measure torsional deflection and cause the damage of circuit.Whole device is reliable, can effectively solve the problem that problem of the prior art.

Brief description of the drawings

Fig. 1 is a kind of structural representation of the motor apparatus of rotatable wiring of the present invention；

Fig. 2 is the close-up schematic view of region of interest in Fig. 1.

Embodiment

With reference to Fig. 1-2, the motor apparatus of rotatable wiring a kind of according to an embodiment of the invention, including pedestal 1 with And the external rotor electric machine 9 on the pedestal 1, there is cam-type connecting part at the left part of the rotor 91 of the motor 92, be separately directed through with for many electric wires 93, and the cam-type connecting part 92 by two connected slide bars 95 with it is solid Pressure-producing part 5 of the Dingan County on the pedestal 1 is rotatably connected, and circuit torsion is slidably supported with two slide bars 95 Disk 8, many electric wires 93 can mutually twist after the circuit reverse plate 8 is passed through from the motor and add with described Binding post 59 on splenium part 5 is electrically connected, and the piston piece 53 pressurizeed by spring 51 and institute are provided with the pressure-producing part 5 Two expansion links 531 for stating piston piece 53 pass the pressure-producing part 5 and are rotatably connected with the circuit reverse plate 8, wherein, The both sides of the cam-type connecting part 92 are respectively symmetrically provided with the two split fix framves that can be slided in the pedestal 1 6, each split fix frame 6 is provided with multiple positioning protrusions 61, pushing of the circuit reverse plate 8 in the piston piece 53 It is lower with being located at respectively on described two split fix framves 6 and two relative positioning are protruded 61 left side plans and rotatably engaged, The cam-type connecting part 92 for each revolution can open on described two split fix framves 6 top once, in the piston piece Under 53 pushing the circuit reverse plate 8 can stepping to the right and be bonded on the right side two on described two split fix framves 6 Relative positioning protrusion 61, so that the wire twist section 931 between the circuit reverse plate 8 and the pressure-producing part 5 Length increase；Counter 11 is installed, the right part of the rotor 91 of the motor 9 is provided with the inwall of the right-hand member of pedestal 1 The detected body 12 that can be detected by the counter 11, so as to accurately learn the rotation number of turns of the rotor 91.

Exemplarily or advantageously, wherein, two sides of the circuit reverse plate 8 are used to and the convex for inclined-plane 88 The right side inclined-plane for going out 61 cooperates, in favor of moving right the step-by-step movement of the circuit reverse plate 8.

Exemplarily or advantageously, wherein, the cavity of the pressure-producing part 5 residing for the spring 51 only passes through intercommunicating pore 52 and be in communication with the outside so that the piston piece 53 is moved right speed controlled and slowed down.

Exemplarily or advantageously, wherein, the motor be servomotor or stepper motor.

Exemplarily or advantageously, wherein, the periphery of the external rotor of the motor is provided with sliding tooth 96.

Because the distance that motor circuit twists or twisted together step-by-step movement can be adjusted according to the rotating cycle of motor, because This, when motor turns to be in low rotating cycle, the length that its electrical wiring twists is shorter, the kink position of this controllable circuit Putting makes it since apart from motor remote position and gradually develops to the position close to motor, thus avoids circuit kink from starting Betide at the position of motor or certain specific location, so as to avoid result in the excessive torsional deflection of local line and cause The damage of circuit.

In the process of running, the stepwise motion of circuit reverse plate 8 can either control the length of kink circuit, again can be right Circuit afterwards is combed and oriented, so that it is guaranteed that avoiding what is excessively wound or knot close to the line parallel extension of motor drive direction Phenomenon occurs.

Whole device is reliable, can effectively solve the problem that problem of the prior art.

Those skilled in the art can be clear and definite, can in the case of the overall spirit of the present invention and design is not departed from To make the various modifications for above example.It is each fallen within protection scope of the present invention.The protection scheme of the present invention It is defined by claims appended hereto.
