Abstract
The utility model discloses a high-speed numerical control hob relieving lathe which is high in machining precision and smooth in finished surface. A linear motor is adopted in the high-speed numerical control hob relieving lathe to replace a transmission chain, the response time of the reciprocating motion in the X-axis direction of the lathe is shortened, the process of accelerating and decelerating is shortened, a double-lead worm gear pair is adopted, the clearance between a worm and a worm gear is reduced, and more accurate feed in the machining process is achieved.
Description
Technical field
The present invention relates to produce the lathe equipments field of hobboing cutter, be particularly related to a kind of by linear electric motors and round trip gear pair in conjunction with realizing under the High-speed machining state that little feeding is carried out in processing to teeth, guarantee accurate machining accuracy and improve, can also guarantee to obtain simultaneously the high-speed numeric control hobboing cutter relieving lathe of good surface smoothness.
Background technology
Hobboing cutter is a kind of high-efficient gear process tool, and it is directly determining the machining accuracy of gear.Tradition hobboing cutter relieving lathe adopts the mechanical gear driving-chain, with cam, realizes the teeth motion.Due to the transmission chain length, loss of significance is very large, and bearing capacity is limited, is difficult to realize high speed, efficient, high-precision teeth requirement; The inevitable gap of long driving-chain is very large, and therefore traditional hobboing cutter relieving lathe is difficult to realize " little feed ", can not realize small feed feeding, is difficult to improve the surface roughness of product; Owing to being gear transmission chain, when changing product, the operator will frequently calculate and change change gear and cam, and for the hobboing cutter product that is all basically Single unit job lot production, unproductive time is very high, has a strong impact on productivity ratio, and will lay in a large amount of change gears.On machine operation, each circulation will be pressed button and turnover cutter back and forth, and very frequent, labour intensity is very high.
Some numerical control relieving lathes also appear in market in the recent period, but are simple numerical control transformation, for X-axis or the lead screw transmission of the frequent motion of teeth, slide rail or the traditional drift gap that disappears, therefore, be difficult to realize the motion of high speed teeth, could not solve high speed, efficient, high-precision teeth requirement.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of high-speed numeric control hobboing cutter relieving lathe, its objective is and utilize linear electric motors to shorten along the reciprocating response time of lathe X-direction, shorten the process of accelerating, slowing down, adopt two helical pitch worm gears, reduce the gap between worm screw and turbine, realize in process more accurate to feeding.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of high-speed numeric control hobboing cutter relieving lathe, it comprises base, be provided with the guide rail that arranges along the base Z-direction on base, slidably connect the Z-direction slide carriage that moves along Z-direction on described guide rail, be fixed with the tool guide that arranges along the base X-direction on described Z-direction slide carriage, described tool guide slidably connects the knife rest supporting plate that moves along X-direction, and described knife rest supporting plate is provided with the draw-in groove of mounting tool post; Described base one end is provided with the main shaft turntable, the described base other end is provided with tailstock corresponding to the main spindle's of main shaft turntable, the drive motors of hobboing cutter relieving lathe adopts linear electric motors, and the driving gear pair in described main shaft turntable adopts two helical pitch worm gears.
The arranged on left and right sides mask of the worm screw of described pair of helical pitch worm gear has different helical pitches, the helical pitch of the same side be transverse tooth thickness that equate and worm screw from the end of worm screw to other end progressive additive or attenuate equably.
pass through technique scheme, a kind of high-speed numeric control hobboing cutter relieving lathe provided by the invention, traditional chain transmission of adopting linear electric motors to replace, effectively solved under moving back and forth at a high speed the requirement to kinematic accuracy, adopt two helical pitch turbo tooth wheel sets, the left side of worm screw, right two sides have different helical pitches, the helical pitch of worm screw the same side be transverse tooth thickness that equate and worm screw from the end of worm screw to other end progressive additive or attenuate equably, make transverse tooth thickness change continuously, reduced the gap between worm screw and turbine, reduced the error of transmission, improved the precision that adds the feeding in man-hour.
