Abstract
A self-lubrication cooled type gear shaper spindle structure comprises a spindle, wherein a spindle sleeve is arranged outside the spindle, and is embedded in a tool rest body; an oil inlet and an oil inlet are formed in the upper end of the spindle sleeve; spiral oil grooves are formed in the spindle sleeve; a plurality of ring-shaped cooling grooves are distributed on the excircle of the spindle sleeve; and the lower ends of the ring-shaped cooling grooves are communicated with the spiral oil grooves. According to the invention, the two spiral oil grooves are formed in the spindle sleeve, depending on the reciprocating movement of the spindle, oil is introduced into a friction zone to form a lubricating oil film so as to realize the purpose of lubrication and prevent grinding damage of the spindle; as the ring-shaped cooling grooves are distributed on the excircle of the spindle sleeve, and the lower ends of the ring-shaped cooling grooves are communicated with the spiral oil grooves, only one pair of openings are communicated between every two ring-shaped cooling grooves, and are distributed symmetrically, the lubricating oil flows to each cooling groove in the return process to take away heat of the spindle sleeve, which is generated by friction and impacting, so that the spindle sleeve is ensured to be fully cooled, the thermal deformation of the spindle sleeve becomes very small, and the grinding die of the spindle can be prevented.
Description
Technical field
Patent of the present invention relates to the main axis of gear shaper structure, particularly a kind of main axis of gear shaper structure with main shaft rotation and past anti-motion.
Background technology
On existing gear shapping machine and many main equipments, often use main shaft directly as transmitting powerful main motion, its rotary speed is high, fast toward anti-motion, and precision is high.But, moving owing to being engraved in during main shaft, and between main shaft and the collar bush gap little, stressed large, lubricated insufficient, the long temperature of temperature is fast, causes main shaft easily to pull collar bush and locking main shaft.Particularly on gear shapping machine, because main shaft has ballistic motion up and down reciprocatingly, main shaft damages so that the teeth directional of workpiece and profile accuracy are overproof, directly damages cutter when appearing the main shaft locking.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, a kind of self-lubricate cooled main axis of gear shaper structure that can guarantee main shaft sufficient lubrication, cooling is provided.
The object of the present invention is achieved like this: a kind of self-lubricate cooled main axis of gear shaper structure, it comprises main shaft, main shaft is provided with collar bush outward, main shaft moves up and down in collar bush and rotatablely moves, collar bush is set in the tool-post structure, be respectively equipped with oil-in and oil-out in the upper end of collar bush, be provided with helical oil groove in the collar bush, the cylindrical of collar bush is furnished with multiple tracks annular cooling bath, the lower end of annular cooling bath communicates with helical oil groove, and main shaft, collar bush, tool-post structure and oil-in and oil-out form a closing oil path circulatory system.
It is matched in clearance between main shaft and the collar bush.
Collar bush is provided with sealing ring.
Only have place's opening to communicate between each annular cooling bath, opening is symmetrically distributed between the adjacent shape cooling bath.
Described helical oil groove is twice.
Self-lubricate cooled main axis of gear shaper structure provided by the invention, be processed with the twice helical oil groove in the collar bush, allow be full of lubricating oil in the whole friction zone oil groove, bring oil into friction zone by the reciprocating motion of main shaft and form lubricating oil film, reach lubricated purpose, prevent the main shaft loss; Cylindrical at collar bush is covered with annular cooling bath, the lower end of cooling bath communicates with oil-way, only have place's opening to communicate between each annular cooling bath, opening is symmetrically distributed between the adjacent cooling bath, lubricating oil flows to each cooling bath in backhaul like this, and collar bush because the heat that friction and impact produce is taken away, has been guaranteed the abundant cooling of collar bush, so that the collar bush thermal deformation is very little, prevent the main shaft fault.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the large structural representation of main shaft of the present invention.
Fig. 3 is that the P of Fig. 2 is to view.
The specific embodiment
Structure of the present invention as Figure 1-3, a kind of self-lubricate cooled main axis of gear shaper structure, it comprises main shaft 4, main shaft one end is provided with hangs broach shell 6, the main shaft 4 outer collar bushes 3 that are provided with, main shaft 43 moves up and down and rotatablely moves in collar bush, collar bush 3 is set in the tool-post structure 2, be respectively equipped with oil-in 1 and oil-out 7 in the upper end of collar bush 3, be provided with helical oil groove 8 in the collar bush 3, the cylindrical of collar bush 3 is furnished with multiple tracks annular cooling bath 9, and the lower end of annular cooling bath 9 communicates with helical oil groove 8, main shaft 4, collar bush 3, tool-post structure 2 and oil-in 1 and oil-out 7 form a closing oil path circulatory system.Be matched in clearance between main shaft 4 and the collar bush 3, join the gap between 0.005-0.01mm.
Operation principle of the present invention is as follows: main shaft 4 can be delivered to huge impulsive force F on the collar bush 3 when collar bush 3 interior reciprocating motion, and main shaft 4 is also transmitting moment of torsion M simultaneously.Main shaft 4 is very little with the gap of collar bush 3, on the contact-making surface very large impulsive force and frictional force must be arranged, and the temperature quick heating causes the main shaft fault.This device injects the lubricating oil of certain pressure by oil-in 1, when main shaft 4 in collar bush 3 when moving up and down and rotatablely moving, lubricating oil enters into friction zone through two helical oil grooves 8, allow and be full of lubricating oil in the whole friction zone oil groove, and rely on the reciprocating motion of main shaft to bring oil into friction zone formation lubricating oil film, reach lubricated purpose, prevent main shaft 4 losses.
In addition, because collar bush 3 cylindricals are covered with annular cooling bath 9, the lower end of cooling bath 9 communicates with oil-way 8, because only have place's opening to communicate between each annular cooling bath 9, opening is symmetrically distributed between the adjacent cooling bath 9, lubricating oil flows to each cooling bath 9 in backhaul like this, collar bush 3 is taken away owing to the heat that rubs and impact produces, guarantee the abundant cooling of collar bush 3, so that collar bush 3 thermal deformations are very little, prevented main shaft 4 faults.
