Description
Technical field
The present invention relates to technical field of motors, especially a kind of line handspike motor that has electro-magnetic braking device.
Background technology
Line handspike motor be a kind of with electric energy change into push rod straight reciprocating motion can power-jdriven gear, can be used in the various simple or complicated technological processes using, to realize far distance controlled, centralized control or control automatically as executive component.Extensively apply to body-building apparatus, medicine equipment, furniture, automobile, electric power, machinery, metallurgy, traffic, mine, oil, chemical industry, lifting, transportation, building, grain and raise industries such as processing.Have dependable performance, be active in one's movements, operate steadily, push-pull effort is identical, characteristics such as good environmental adaptability.Compare with execution machineries such as hydropneumatics, have following advantage:
1. cost is low, has saved oil pump, fuel tank, air compressor machine and many complicated pipelines and other auxiliary equipment.
2, energy consumption is low, the Conversion of energy link in the middle of having saved by motor direct-drive, and the overall efficiency height, thus reduced energy consumption.
3, no oil contamination, owing to avoid adopting oil or gas transmission, the seepage of no fluid makes pollution problem obtain basic solution.
4, installation and maintenance are very simple and convenient.Only need simply push rod to be installed on support or the suspension bracket, energized can be used.Need special maintenance during normal the use hardly.
The structure of existing line handspike motor generally includes motor and rotatablely moving of motor is changed into the transmission device of the straight reciprocating motion of push rod.The version of transmission device has a lot.Such as: gear reduction adds gear, rack gear; Gear reduction adds screw mandrel, nut transmission mechanism etc., and the structure of transmission device with the most use at present, that operation is the most steady, transmission efficiency is high, noise is low is: have worm screw, Worm wheel transmission mechanism, wear a screw mandrel in the worm gear endoporus, worm gear and screw mandrel engagement, the driven by motor worm screw is rotated, drives the worm gear rotation by worm gear, worm-drive, make the minor leading screw moving linearly in the worm gear, screw mandrel can directly also can install push rod additional as push rod on screw mandrel, utilize the rotating of motor to order about push rod and do reciprocating linear motion.Can stop for guaranteeing that push rod can remain on the optional position exactly and move to assigned address, brake apparatus also is housed on the line handspike motor, the brake apparatus of existing line handspike motor generally adopts the conical disc brake, it is braking force that the conical disc brake relies on spring that the conical surface friction masterpiece is provided, the magnetic field force that then needs motor when not braking is as breakaway force, so motor need be designed to eccentric magnetic field, overcomes spring force by magnetic field force, rubbing surface is broken away from, can lose efficiency of motor like this; And braking force is less, and it is unreliable to brake; Homogeneity of product is poor, and disqualification rate is higher.
Summary of the invention
The technical problem to be solved in the present invention is: overcome existing line handspike motor and adopt the conical disc brake to make brake apparatus, because it is braking force that the conical disc brake relies on spring that the conical surface friction masterpiece is provided, then need the magnetic field force of motor as breakaway force when not braking, motor need be designed to eccentric magnetic field, overcome spring force by magnetic field force, rubbing surface is broken away from, and make electric efficiency impaired; And brake apparatus braking force is less, and it is unreliable to brake; Homogeneity of product is poor, the more high deficiency of disqualification rate.The invention provides a kind of line handspike motor, its brake apparatus is the electro-magnetic braking device of cylindrical mode of braking, can guarantee that push rod remains on the optional position very exactly and moves to assigned address and can stop.
The technical solution adopted for the present invention to solve the technical problems is: a kind of line handspike motor, have motor and rotatablely moving of motor changed into the transmission device of the straight reciprocating motion of push rod, motor has motor shaft, front end housing and rear end cap, the motor shaft front end is fixedlyed connected with transmission device, be provided with fan in the front end housing of motor or the rear end cap, fan is fixedly mounted on the motor shaft, the fan blade that fan has the outer ring and is arranged in the outer ring and is structure as a whole with the outer ring, the radial outside of fan is provided with the electro-magnetic braking device of the outer ring of braking fan, and electro-magnetic braking device is fixedlyed connected with front end housing or rear end cap.
Specifically, described electro-magnetic braking device has braking sleeve and restraining coil skeleton, the restraining coil skeleton is fixedlyed connected with front end housing or rear end cap, the restraining coil skeleton is equipped with restraining coil on the outer ring, static iron core and moving iron core are housed in the restraining coil skeleton, static iron core and the riveted joint of restraining coil skeleton upper end, moving iron core is arranged on the static iron core below, be slidingly matched with the restraining coil skeleton, restraining coil skeleton lower end is provided with spring groove, be provided with spring in the spring groove, spring housing is contained on the moving iron core, also is provided with convex shoulder or back-up ring is housed below spring on the moving iron core, and braking sleeve is fixedlyed connected with moving iron core lower end.
When motor gets electric work, restraining coil simultaneously electric, moving iron core overcomes the active force and the static iron core adhesive of spring, is contained on the braking sleeve servo-actuated iron core of moving iron core lower end to move, and breaks away from the outer ring of fan, brake off, motor operate as normal; When the motor dead electricity, restraining coil is dead electricity simultaneously, restraining coil magnetic field disappears, moving iron core is moved down by the active force of spring, and braking sleeve is pressed on the outer ring of fan, and braking sleeve and fan outer ring produce friction and force rotating fan to stop operating, because fan is fixedly mounted on the motor shaft, fan stops operating, and then motor shaft goes out to stop operating, and motor is forced to braking.
For the described fan that reduces cost is a working of plastics, for the fan temperature distortion that prevents working of plastics causes the inefficacy that is connected with motor shaft, fan adopts interference fit or spline to be connected with motor shaft.
The invention has the beneficial effects as follows, line handspike motor of the present invention installs fan additional in the front end or the rear end of motor shaft, adopt the outer ring of electromagnetic braking braking fan, be beneficial on the one hand distributing of the heat that produces in the machine operation, excellent in heat dissipation effect, compared with prior art, cooling effect improves more than 40%; On the other hand, improved transmission efficiency, compared, improved more than 25% with the existing mechanical braking; The present invention is simple in structure in addition, and cost is low, and cost has reduced more than 20%; And the reliability of motor improves greatly.
