Abstract
The utility model discloses a double-speed micro-feed mechanism, which comprises a rapid feed mechanism and a micro-feed mechanism. The rapid feed mechanism comprises a base and a screw rotatably arranged on the base and driven by a feed motor. The screw is screwed with a nut through threads. A guide rod is fixedly arranged on the base, wherein the guide direction of the guide rod is parallel to the axis of the screw. The nut comprises a guide sliding seat slidably arranged on the guide rod in an oriented manner. The micro-feed mechanism comprises a cylindrical shell fixed on the nut, an electromagnetic coil fixed in the cylindrical shell and a rare earth giant magnetostrictive rod for penetrating the electromagnetic coil and generating an axial stretching strain under the action of the magnetic field of the electromagnetic coil. The axis of the rare earth giant magnetostrictive rod is parallel to the axis of the screw. According to the utility model, since the double-speed micro-feed mechanism adopts two feed mechanisms to realize the double-speed feed, the machining time is effectively saved. Meanwhile, the high-precision machining is realized.
Description
Technical field
The utility model relates to and is used for machinery, jewelry, the accurately machined feed mechanism of gold and silver.
Background technology
In existing machinery fine finishining field, adopt swivel feeding mechanism mostly.The shortcoming of such mechanism is a complex structure, and precision is not high, and response speed is slow.As: the worm and gear feed mechanism, design cost is bigger, complex structure, it is bigger to take up room, and is unfavorable for the compact requirement of swivel feeding mechanism; The cam-type feed mechanism, cam type surface is complicated, and the processing technology difficulty is bigger, and cost is high.
The utility model content
The purpose of the utility model be to provide a kind of can either be fast double speed micro-feed mechanism that just location again can microfeed.
The technical scheme of the utility model is: a kind of double speed micro-feed mechanism; It is characterized in that: comprise fast feed mechanism and micro-feed mechanism; Fast feed mechanism comprise on base and the base rotate assembling use motor-driven leading screw by feeding; Be installed with nut through screw thread on the leading screw; Also be fixed with the guide post of guide direction and lead screw shaft line parallel on the base; Nut comprises the guiding slide of guiding slidable fit on guide post, and said micro-feed mechanism comprises the interior fixing solenoid of the tubular shell, the tubular shell that are fixed on the nut, is arranged in the rareearth super magnetostrictive rod that under the effect of the magnetic field of solenoid, produces the axial stretching strain in the solenoid, the parallel axes of excellent axis of rareearth super magnetostrictive and leading screw.
Also use motor on the tubular shell of said micro-feed mechanism along the axially directed processing of revolution action that is used to export processing of moving that the flexible strain output that is equipped with the rareearth super magnetostrictive rod is in transmission connection of rareearth super magnetostrictive rod.
The double speed micro-feed mechanism of the utility model is through the double speed feeding of two feed mechanisms; Can effectively save process time; After micro-feed mechanism reaches Working position, control little feeding through the electromagnetism size that changes solenoid, the adjustment of the rareearth super magnetostrictive rod of driving; Can realize high-accuracy processing, precision can reach nanoscale; And through Electromagnetic Drive, so product adds and can make that by electromagnetic property the entire mechanism response speed is fast through changing man-hour, less than 1 μ s; Just can change little amount of feeding owing to only need to change the magnetic field size, therefore only need to come this unitary variant to control little amount of feeding, be beneficial to programming Control, eliminate human error through the control electric current.

Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2; The embodiment of the double speed micro-feed mechanism of the utility model comprises fast feed mechanism and micro-feed mechanism; Fast feed mechanism comprise on base 1 and the base 1 rotate assembling by the leading screw 2 of feeding with motor 7 drivings; Be installed with nut 3 through screw thread on the leading screw 2; Also be fixed with the guide post 4 of guide direction and leading screw 2 parallel axes on the base 1; Nut 3 comprises the guiding slide 31 of guiding slidable fit on guide post 4, and said micro-feed mechanism comprises tubular shell 5, the tubular shell 5 interior solenoids of fixing 51 that are fixed on the nut 3, the rareearth super magnetostrictive rod 52 that is arranged in the generation axial stretching strain under the effect of the magnetic field of solenoid 51 in the solenoid 51, and the rareearth super magnetostrictive rod is the barred body of being processed by rare earth ultra-magnetostriction material; Rare earth ultra-magnetostriction material is a kind of known Tb-Dy-Fe alloy; It has very high strain value under the effect of magnetic field, extensively utilize rare earth ultra-magnetostriction material that change in size output mechanical displacement takes place under the effect of variation magnetic field in the prior art, no longer its concrete structure is introduced here.The parallel axes of rareearth super magnetostrictive rod 52 axis and leading screw 2.On the tubular shell 5 of micro-feed mechanism also along the axially directed processing of revolution action that is used to export processing of moving that the flexible strain output that is equipped with rareearth super magnetostrictive rod 52 is in transmission connection of rareearth super magnetostrictive rod 52 with motor 6.Rareearth super magnetostrictive rod 52 is connected with the base of processing with motor 6 tail ends through drive link 53.Certainly in other embodiment of the utility model, double speed micro-feed mechanism itself also can not provide processing with motor but with the supporting use of existing machining tool.
The embodiment of the utility model in use; Realize the fast forwarding and fast rewinding of micro-feed mechanism through the leading screw revolution; After arriving Working position; Solenoid 51 in the micro-feed mechanism electric generation field drives rareearth super magnetostrictive rod 52 stretching motions and drive processing with the advancing or retreat of motor 6, realize accurately locating, precision can reach the nm level.
