Abstract

The utility model discloses a DC reciprocating linear electric motor, which belongs to the technical field of the electric motor. The DC reciprocating linear electric motor is designed according to the electric magnet principle of the direct current spiral tube type; the DC reciprocating linear electric motor which corresponds to two direct current spiral tube-type electric magnets can be butted by a screw bolt through a threaded flange disk; a magnetic isolating plate which is arranged between the two threaded flange disks can prevent the magnetic force lines from dispersing; the straight-line electric motor coils are made to sequentially conduct the continuous energization and power cut, and accordingly, the armature iron can conduct the reciprocating movement, and the straight-line motion can be realized. The utility model can complete the straight-line motion through replacing the departed crankshaft or four-bar mechanism, the cam mechanism, etc.

Description

DC reciprocating linear motor

The utility model belongs to machine field.

At present, straight-line plant equipment, mainly adopt following three kinds of modes: the one, by bent axle or quadric chain, cam mechanism etc. change rectilinear motion into to motor through gearbox, the 2nd, adopt the alternating current asynchronous linear electric motors, the 3rd, handle as motive power by air pressure or oil pressure and to finish rectilinear motion.Above-mentioned three kinds of modes exist power consumption big in various degree, cost height, problems such as equipment complexity.

The utility model is to join correspondent control circuits according to dc solenidal formula electromagnet principle design De ， And, thereby overcomes the deficiency of present straight-line plant equipment.

Direct current is toward multiple line line motor, is equivalent to the work that is together in series of two dc solenidal formula electromagnet.Dc solenidal formula electromagnet sits back and waits forms that by armature, shell (yoke), coil, brass lid, end cap, a machine technical essential of the present utility model is:

One, two shells (yoke) by Bolt Connection, have a magnetic isolation plate between two screwed flange dishes by two screwed flange dishes, and screwed flange dish and shell (yoke) are by the screw thread butt joint, and magnetic isolation plate is that brass is made, and thickness is between 1～2 centimetre.

The 2nd, an end and the end cap contact position of armature are taper; The other end of armature and end cap contact position are trapezoidal; End that armature is trapezoidal and arbor thread connection, the taper of end cap and step surface are gag bit pad, and this pad is made for nylon or hard rubber.

The 3rd, the copper bush surface is added with nylon bush, the thickness of this lining between the 1-2 millimeter,

The 4th, between copper bush and the shell (yoke) several coils are arranged, what of coil are by the decision of the stroke of the reciprocal linear electric motors of direct current size, and the big more coil of stroke is many more.

The utility model is compared with existing straight-line plant equipment, and it is simple to have manufacturing process, the efficient height, energy savings, and can the control rate speed, power output size and stroke size provide a kind of novel device for finishing rectilinear motion.

The utility model has following accompanying drawing:

Fig. 1 is the structural representation of the reciprocal linear electric motors of direct current, wherein: 1 be end cap, 2,10 for bolt, 3,4 shells (yoke), 5 for coil (a～f), 6 for copper bush, 7 for nylon bush, 8 for the screwed flange dish, 9 for magnetic isolation plate, 11 for arbor, 12 is gag bit pad, 13 be support, 14 for armature, 15 for oil filler point, 16 be the magnetic conduction air gap.

Fig. 2 is the reciprocal linear electric motors electric control circuit of a direct current schematic diagram, wherein: C4060 is 14 grades of cascaded carry binary counter integrated circuits, C039 is three inputs, four formula ungated integrated circuits, C037 is the two formula ungated integrated circuits of four-input terminal, C187 is that 2-10 system counter/pulsqe distributor integrated circuit, YZ31B reach woods ton power tube, and W7805 is a stable-pressure device, and 2CZ is a silicon rectifier cell, SCK is controllable silicon 3CT

Embodiment of the present utility model sees accompanying drawing 1,2, armature is reciprocating member behind the coil electricity with axle, nylon bush plays wear-resisting effect, copper (or aluminium) lining (claim not only damping ring) is to prevent magnetic line of force short-circuit part (but also playing the leakproof magnetic action), this lining decision electromagnet operate time and release time, when coil after power supply disconnects, magnetic flux φ just reduces gradually, because the variation sensing of magnetic flux φ goes out electromotive force, by Lenz's law as can be known, this induced electromotive force produces electric current in damping ring be the variation that stops magnetic flux, therefore makes the speed of flux decay slack-off, played magnetic damping, thereby prolong release time, the size of damping action at this moment is by time constant T=(L)/(R) decision of damping ring, L is damping ring inductance one circle, and R is the resistance of damping ring.This resistance is relevant with the damping ring thickness by material, and magnetic isolation plate is every magnet assembly, and it can stop the magnetic line of force to disperse, and makes the normal reciprocating motion of armature.

In conjunction with Fig. 2 the control procedure of the reciprocal linear electric motors of direct current, transformer B are described ₁Be the power supply (12V) of linear motor coil,, just control linear electric motors input discrepancy size, transformer B by controllable silicon SCR controllable power voltage swing ₂It is the triggering power supply of power tube Darlington YZ31B and all integrated circuits thereof, C4060 is the pulse frequency generator of certain width, four kinds of frequency 2HZ are arranged, 4HZ, 8HZ, 32HZ, by K switch HZ scalable frequency, thereby regulate the linear electric motors speed, the pulse frequency of C4060 input is through the output 0 of C187,1 ... 9 constantly cycle assignment outputs successively, C039 and C037 convert the YZ31B triggering signal to from the pulse frequency that C187 imports, electric capacity 20P and quartz crystal 32768, resistance 3,9M is the occurrence frequency device, Kx scalable linear electric motors stroke size, linear motor coil is by the constantly energising of (a-f) order, and outage makes the motor armature reciprocating motion.
