Abstract
The utility model relates to an electromagnetic reciprocating motion machine which directly converts electric energy into mechanical energy. The output end of an eliminator power is connected with two electromagnets (1) with opposite magnetic fields and is also connected with a circuit composed of a frequency modulator (4) and an alternating electromagnet (3) which is provided with a working beam (2). Besides, the movable alternating electromagnet (3) is put between the two fixed electromagnets (1) with opposite magnetic fields to cause the center lines of the movable alternating electromagnet (3) and the two fixed electromagnets (1) with opposite magnetic fields to be on the same axis. The machine can be used for matching with a piston, a saw blade, a hammer, a needle head, etc. and can be made into a compressor, a hand-held electric saw, an electric hammer, a sewing machine, etc.
Description
The utility model relates to a kind of electromagnetic type reciprocating motion machine that electric energy is directly changed into mechanical energy.
The more existing reciprocating motion that converts electric energy to mechanical energy all is that the rotation by motor or motor drives speedup or reducing gear and transmission mechanism thereof and realizes.For example, the piston of compressor, the saw blade of electric saw, the tup of electric hammer is so that the reciprocating motion of the syringe needle of sewing machine etc.Drive above-mentioned these reciprocating machine or equipment, complex structure, volume is big, manufacturing cost is high, for reducing cost, increase economic efficiency and wide popularization and application be disadvantageous.
The purpose of this utility model provides a kind of simple suitable, with low cost, electric energy is directly changed into the electromagnetic type reciprocating motion machine of mechanical energy.
For achieving the above object, the utility model is connected to the electromagnet 1 in two opposition magnetic fields at the output of rectifier power source, also be connected to by frequency modulator 4, the circuit of alternating electromagnetism iron 3 formations of working beam 2 is housed, and mobilizable alternating electromagnetism 3 is placed between two electromagnet 1 fixing, opposition magnetic field, the center line that makes the three is on same axis.
Above-mentioned working beam 2 is to be fixed on the alternating electromagnetism iron 3, and Xiang Yiduan stretches out by an electromagnet 1 wherein.
The utility model has the advantages that: 1. volume is little, in light weight, cost performance is high, with low cost; 2. friction when working, noiselessness, no oil contamination, security reliability height; 3. make easily, be easy to carry, operation and maintenance is simple, saves the energy; 4. purposes is wide, and popularizing application prospect is arranged.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is this practical new construction, the operation principle schematic diagram.
In the drawings, the electromagnet in two opposition magnetic fields is fixed in one sleeve of casing lower end, and in its reciprocating stroke decision between the two, the trip promptly is the reciprocating operating distance of working beam to the distance between them according to alternating electromagnetism iron.This working beam is that the left end from alternating electromagnetism iron stretches out.
When rectifier power source is connected 220 volts of alternating currents, the electromagnet and the frequency modulator in two opposition magnetic fields have, the electromagnetic field in two opposition magnetic fields is respectively N in the end polarity near alternating electromagnetism iron, and the frequency modulation alternating current of frequency modulator output changes the polarity of alternating electromagnetism iron.When alternating electromagnetism iron left end polarity is S, right when be N, then produce attraction with the N utmost point near the electromagnet in the opposition magnetic field of left end, with electromagnet generation repulsive force, then make the working beam of nonmagnetic substance and alternating electromagnetism iron together to left movement near right-hand member.Otherwise, when alternating electromagnetism iron left end polarity is N, when right-hand member is S, working beam is moved right, thereby as long as set the frequency modulator state, can operate the motion frequency with the Control work bar, realize making the left and right reciprocating purpose of working beam.
The utility model can be used for realizing equidistant or not equidistant reciprocating motion.For example, be used for the piston of compressor, the tup of electric hammer, the saw blade of electric saw and the syringe needle of sewing machine etc. are realized reciprocating motion.
Rectifier power source of the present utility model, frequency modulator are available on market.The iron core of electromagnet and coil and working beam can have reciprocating requirement together to design according to above-mentioned, can make in general processing factory, so this machine is made easily and applied.In addition, be noted that, then can save frequency modulator, and can directly set up alternating magnetic field, make working beam toward double action with DC power supply if, install a power positive cathode diverter switch at the end place of electromagnet 1 in two opposition magnetic fields.
Claims (2)
1. electromagnetism reciprocating motion machine, mainly by rectifier power source, frequency modulator and electromagnet are formed, it is characterized in that being connected to the electromagnet (1) in two opposition magnetic fields at the output of rectifier power source, also be connected to by frequency modulator (4), the circuit that the alternating electromagnetism iron (3) of working beam (2) constitutes is housed, and mobilizable alternating electromagnetism iron (3) is placed between two electromagnet (1) fixing, opposition magnetic field, the center line that makes the three is on same axis.
