In the linear motor slipway, the linear motor has a reasonable structure and a small volume and is easy to assemble; the magnetic shaft of the linear motor is a seamless steel tube, so the roundness of internal and external circles and the accuracy of wall thickness are improved, a magnetic field is more uniform and low-speed performance is improved; a radiating structure of the linear motor has high efficiency, good cooling effect and cooling uniformity; and the rated current is improved by 3 times compared with the conventional linear motor, the rated thrust is improved by 3 times compared with the conventional output, and the efficiency can be maximized.
Description
Technical field
The utility model relates to a kind of linear motor sliding table.
Background technology
Linear motor sliding table of the prior art, the structure that the linear electric motors of use adopt magnetic axis to match with coil.It is inhomogeneous that magnetic axis is assured inside and outside circularity, causes the air gap between magnetic axis and the coil inhomogeneous, thereby loss thrust.And inhomogeneous also the making of circularity installed inconvenience.Permanent magnet weight is heavier, and parcel pipe insufficient strength causes magnetic axis length to be restricted greatly, generally only can accomplish about 2 meters.
Linear electric motors are prone to heating when high-speed motion, linear motor coil internal high temperature of the prior art should not leave, and cause the problem of the local demagnetization of magnetic axis, seriously are can be because of overheated catastrophe failure such as burn, can not long-time running under the high load capacity situation.The overheated operating efficiency that also can reduce linear electric motors of coil.In high speed, high-precision processing field, coil heating can influence its precision, and can't reach best thrust.Easy to wear in the use, wearing and tearing also can reduce its precision.
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art, a kind of linear motor sliding table that prevents that coil temperature is too high to be provided.
For realizing above purpose, the utility model is realized through following technical scheme:
Linear motor sliding table is characterized in that, comprises slide unit and linear electric motors, and linear electric motors comprise magnetic axis and the coil that is provided with around magnetic axis, and said coil is arranged in the housing; Slide unit is connected with housing; The magnetic axis two ends are arranged on the frame.
Preferably, said linear electric motors also comprise circulating water pipe, and circulating water pipe has import and outlet; Said circulating water pipe contacts with coil.
Preferably, said coil and circulating water pipe are arranged in the housing.
Preferably, said circulating water pipe number is two, and two circulating water pipes are arranged at the coil both sides respectively.
Preferably, said magnetic axis comprises seamless steel pipe and permanent magnet, and said permanent magnet is arranged in the seamless steel pipe.
Preferably, described frame is provided with guide rail, and described slide unit is provided with the slide block that matches with guide rail.
Linear motor sliding table in the utility model, its structure of the linear motion actuator is reasonable, volume is little, is easy to assembling.The linear electric motors magnetic axis adopts seamless steel pipe, has improved the circularity of inside and outside circle and the precision of wall thickness, makes magnetic field more even, and then improves low-speed performance.The longer degree of disturbing of magnetic axis is big more, adopts seamless steel pipe to improve linearity and rigidity, and then the length of magnetic axis can be accomplished 3.5 meters in allowing degree of disturbing.Linear electric motors volume in the utility model is little, do not take setting height(from bottom).Its radiator structure efficient is high, good cooling results and even.Can avoid coil overheated and influence precision.Rated current than existing linear electric motors improves 3 times, and normal thrust also improves 3 times than former output, the implementation efficiency maximization.The contactless work of coil and magnetic axis can not produce wearing and tearing.Adopt seamless steel pipe and fall heat abstractor, can guarantee the high accuracy of slide unit, high acceleration, the output of high thrust, reduce energy consumption, efficient is higher.

Like Fig. 3, shown in Figure 4, linear electric motors comprise magnetic axis 30 and are arranged at the housing 40 on the magnetic axis 30.Magnetic axis 30 comprises seamless steel pipe 31 and permanent magnet (not shown).Permanent magnet is arranged in the seamless steel pipe 31.Be provided with coil 50 in the housing 40.Coil 50 is provided with around magnetic axis 30.Coil 50 is provided with lead-out wire 51.Lead-out wire 51 is used to connect power supply.Be provided with two circulating water pipes 60 in the housing 40.Two circulating water pipes 60 are arranged at coil 50 both sides respectively.Each circulating water pipe 60 has import 61 and outlet 62; Said circulating water pipe 60 contacts with coil 50.
Like Fig. 1, shown in Figure 2, slide unit 20 is connected with housing 40.Magnetic axis 30 two ends are arranged on the frame 10.
Recirculated water gets in import 61 in the circulating water pipe 60, flows out from exporting 62.In the flow process, recirculated water can be taken away the heat that coil 50 produces in circulating water pipe 6, reduces the temperature of coil 50.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
