Description
Technical field
This utility model belongs to lathe technological equipment field, it is specifically related to the follow-rest of the uniform reducing slender axles of turning, it is characterized in the transmission by machinery, when making the uniform reducing slender axles of turning, with the cutter mechanism telescopic variation with cutter, synchronize to change as such in the same direction, to adapt to the even variation of shaft diameter, it is achieved hold up the purpose of axle with cutter.
Background technology
The turning of slender axles, due to its rigidity, is always up the technical barrier of processing.For ladder slender axles, owing to its diameter is constant in certain length, generally can use follow-rest, to offset Cutting Force, make axle not deform because of poor rigidity in the course of processing, it is ensured that the precision of turning.And for the slender axles of uniform reducing, owing to, in turning process, shaft diameter is even variation, this allows for common follow-rest countershaft cannot carry out rigid protective, turnery processing is made to cannot be carried out.
Therefore, for slender axles zero component of uniform reducing, redesign is substantially employing segment design and becomes tiny axle part, carry out after processing being assembled into thin and long units.This adds increased production cost, reduce serviceability and the life-span of zero component, become manufacturing one big defect.Therefore we have developed the follow-rest of the uniform reducing slender axles of a kind of turning, and this follow-rest is by the transmission of machinery, when making the uniform reducing slender axles of turning, with the cutter mechanism telescopic variation with cutter, synchronize to change as such in the same direction, to adapt to the even variation of shaft diameter, it is achieved hold up the purpose of axle with cutter.
Summary of the invention
The purpose of this utility model is in that the uniform reducing slender axles follow-rest of innovative design one turning, this follow-rest is by the transmission of machinery, when making the uniform reducing slender axles of turning, with the cutter mechanism telescopic variation with cutter, synchronize to change as such in the same direction, to adapt to the even variation of shaft diameter, it is achieved hold up the purpose of axle with cutter, to guarantee the turning accuracy of uniform reducing slender axles.
The uniform reducing slender axles follow-rest of turning that this utility model provides, circular disk surface on follow-rest seat is radially mounted three chucks, the lathe tool forward part being sandwiched on lathe square tool post may pass through one of them chuck and fixed thereon, another two chuck is separately installed with inner end and protects axostylus axostyle with what protect axle bearing, corresponding each chuck is provided for its guiding mechanism movable to circular disk center, it is respectively arranged with tooth bar in the both sides of each chuck, make to engage each other between them by two idle wheel gears being arranged on circular disk between the tooth bar that adjacent two chucks are relative.
In above-mentioned, guiding mechanism is made up of the slide block stretching into gathering sill on the gathering sill being opened on circular disk and chuck.
In above-mentioned, slide block is provided with, at the opposite side of circular disk, the set screw that anti-chuck comes off.
In above-mentioned, the axle of carrier pulley of each idle wheel gear is arranged in the axis hole of circular disk, and axle of carrier pulley has through hole, fixing bolt pass through hole and nut screw connection tightening on circular disk.
In above-mentioned, coaming plate and the cover plate of the both sides that chuck is fixed as one by base plate and base plate form, and wherein, cover plate is anchored on the coaming plate of both sides by clamping screw, is provided with housing pin at cover plate.
In above-mentioned, slide block is fixed on the base plate of chuck.
This utility model passes through rack and pinion drive mechanism, when making the uniform reducing slender axles of turning, with the telescopic variation of cutter, synchronizes to change as such in the same direction, to adapt to the even variation of shaft diameter, it is achieved hold up the purpose of axle with cutter.
