Abstract
The invention discloses a high-speed magnetic air cylinder which comprises a cylinder barrel, buffer end covers at two ends of the cylinder barrel, a piston in the cylinder barrel and a locking screw rod of an inner magnetic ring lock, wherein the locking screw rod of the inner magnetic ring lock is provided with an inner magnetic ring; the cylinder barrel is externally provided with an outer magnetic ring; the magnetic force of the inner and outer magnetic rings is 4200+/-200GS, and simultaneously two groups of inner and outer magnetic rings are added; and two sides of the cylinder barrel are provided with slide frame guide rods, and two ends of each slide frame guide rod are provided with linear bearings which are used for bearing guides and have high accuracy. The magnetic air cylinder has the advantages of good safety and high reliability.
Description
Technical field
The invention belongs to the pneumatics field, relate in particular to a kind of high speed magnetic cylinder.
Background technique
Along with the raising of industrial automation level, China's pneumatic industry obtained swift and violent development at nearly 15 years, and is annual with 20% speed increment.Its huge market demand, development prospect is wide.Common in the market magnetic cylinder moves when load is heavier, under the situation of velocity of piston greater than 700mm/S, breaks down easily, has potential safety hazard.
Summary of the invention
At above-mentioned technological deficiency, the technical problem that the present invention need solve provides the good high speed magnetic cylinder of a kind of Safety performance.
The technical problem that the present invention need solve is achieved through the following technical solutions: a kind of high speed magnetic cylinder, the buffering end cap, the piston in the cylinder barrel and the internal magnetic ring locking locking screw that comprise cylinder barrel, cylinder barrel two ends, internal magnetic ring locking locking screw is provided with internal magnetic ring, outside cylinder barrel, be provided with outer magnetic ring, the magnetic force of outer magnetic ring is 4200 ± 200GS in described, increases by two groups of internal magnetic rings simultaneously and increases by two groups of outer magnetic rings; Be provided with the balladeur train guide rod in the both sides of cylinder barrel, be provided with at the two ends of balladeur train guide rod and make carrying guiding and high-precision linear bearing.
Further: in above-mentioned high speed magnetic cylinder, described buffering end cap is provided with the buffering pin, also is provided with buffer ring and cushion collar successively in nearly buffering end caps.
Compared with prior art, above-mentioned high speed magnetic cylinder, the buffering end cap, the piston in the cylinder barrel and the internal magnetic ring locking locking screw that comprise cylinder barrel, cylinder barrel two ends, internal magnetic ring locking locking screw is provided with internal magnetic ring, outside cylinder barrel, be provided with outer magnetic ring, the magnetic force of outer magnetic ring is 4200 ± 200GS in described, increases by two groups of magnet rings simultaneously; Be provided with the balladeur train guide rod in the both sides of cylinder barrel, be provided with at the two ends of balladeur train guide rod and make carrying guiding and high-precision linear bearing.With interior outer magnetic ring N42 NdFeB material, magnetic force is improved 4200GS by 3500GS, improve the confining force of magnetic couple, increase by two groups of magnet rings simultaneously; Also improve the confining force of magnetic couple; Two balladeur train guide bar magnetic cylinders are made carrying guiding with the highi degree of accuracy linear axes, under high-speed working condition, move more steadily, freely suitable, are not easy stuck.Two end cap adopts the unsteady gas buffering of band non-return valve function, can make cylinder piston slow down reposefully under the situation of high speed operation, prevents to cause piston and slide unit to break away from because of impacting bounce-back.The operating speed scope of this magnetic cylinder is 50～1000mm/s, cylinder diameter
The corresponding atmospheric pressure of its magnetic couple confining force is 0.84～0.85.
