Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in drawings, the utility model comprises base 1, giant magnetostrictive rod 2, phase transformation inner sleeve 3, phase-change material 4, phase transformation outer sleeve 5, coil rack 6, efferent duct 7, shell 8, cross output push rod 9, pre-compressed spring, upper end cover 11, precompressed nut 12, drive coil 13, input pipe 14, water pump 15 and water tank 16; Giant magnetostrictive rod 2 and cross output push rod 9 is housed on base 1 center small boss, outside giant magnetostrictive rod 2 and 9 times straight-bars of cross output push rod, phase transformation inner sleeve 3, phase-change material 4 and phase transformation outer sleeve 5 is housed successively from inside to outside; The coil rack 6 and the shell 8 of coiling drive coil 13 are housed outside phase transformation outer sleeve 5, form cooling water chamber between phase transformation outer sleeve 5 and the coil rack 6; Coil rack 6 tops connect efferent duct 7 and communicate with water tank 16 and cooling water chamber, and coil rack 6 bottoms connect input pipe 14 and communicate with water tank 16 and cooling water chamber through water pump 15; Cross output push rod 9 upper straight rods are equipped with pre-compressed spring and precompressed nut 12, and the upper end cover 11 of shell 8, pre-compressed spring and precompressed nut 12 constitute the combination prepressing device.
Phase transformation inner sleeve 3, phase-change material 4 and phase transformation outer sleeve 5 constitute phase-change temperature control device, wherein phase-change material such as Iron trichloride hexahydrate crystal, sal glauberi etc.
Phase transformation outer sleeve 5, coil rack 6, efferent duct 7, input pipe 14, water pump 15 and water tank 16 are formed cooling water circulating device.
Described pre-compressed spring is helical spring 10 or disk spring.
By regulating the combination prepressing device that constitutes by output push rod 9, pre-compressed spring 10, upper end cover 11 and precompressed nut 12, can apply different precompressions to giant magnetostrictive rod 2, giant magnetostrictive rod 2 is under the preferable condition of work.Under the effect of input current, drive coil 13 will produce driving magnetic field, and giant magnetostrictive rod 2 length are changed.Because 1 pair of giant magnetostrictive rod 2 of base has supporting role,, show as the displacement output of ultra-magnetostriction microdisplacement driver so the length change amount of giant magnetostrictive rod 2 will externally be exported by output push rod 9.
Under the input current effect, the little driver part of ultra-magnetic telescopic will produce two parts loss: giant magnetostrictive rod 2 hysteresis losses and drive coil 13 ohmic losses.This two parts loss will be come with the form diffusion of heat energy, and the temperature of internal drive will rise rapidly.Giant magnetostrictive rod 2 hysteresis losses will cause mainly that giant magnetostrictive rod 2 temperature raise.Under the effect of the temperature difference, heat passes to phase-change material 4 from giant magnetostrictive rod 2 along phase transformation inner sleeve 3, and it is liquid phase that partial phase change material 4 begins from solid transformation, absorbs heat, keep himself temperature constant substantially simultaneously, so just can keep the temperature of giant magnetostrictive rod 2 constant substantially.The ohmic loss of drive coil 13 will cause mainly that coil temperature raises.Under the effect of the temperature difference, heat will along drive coil 13 radially to both sides conduction, wherein part ring framework 6 along the line passes to cooling water 17.Because the temperature of cooling water 17 is lower than the phase transition temperature of phase-change material 4, the part heat of phase-change material 4 absorptions will pass to cooling water 17 by phase transformation outer sleeve 5 so.Under the drive of water pump 15, cooling water 17 flows into ultra-magnetostriction microdisplacement driver from water tank 16 through input pipe 14, from efferent duct 7 reflow tanks 16, finishes one and circulates again.By a circulation, cooling water 17 can be transferred to external environment to heat from the little driver part of ultra-magnetic telescopic inside, can guarantee that phase-change material 4 did not lose efficacy because of the solid-liquid transformation temperature control all takes place, and the little driver part temperature of whole ultra-magnetic telescopic is remained unchanged substantially, realize suppressing driver temperature rise and thermal deformation errors output, improve output displacement control precision.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection range of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection range of the present utility model.
