Abstract
The invention discloses a bevel gear shaft tooth surface pitch cone locating tool, comprising a tool body provided with a Morse taper shank, a floating type steel ball retaining ring and a tip, wherein the floating type steel ball retaining ring is sheathed in a tooth space at the front end of a processed product and is arranged in a groove arranged at one end of the tool body provided with the Morse taper shank, the floating type steel ball retaining ring leans against a limit step in the groove, and the tip leans against in a central hole at the tail end of the processed product. In the invention, the structural design that the groove is arranged at the end part of the tool body provided with the Morse taper shank is coordinated with the floating type steel ball retaining ring sheathed in the tooth space at the end part of the process product, thus the shaft diameter of the processed product and the cone pitch circle of a gear can be ensured to be maintained on the same axial lead to the utmost extent, the geometric eccentricity of the gear and the shaft diameter is corrected to the utmost extent, the problem that a gear ring runs out in the processing process can be prevented, and the product accuracy is greatly improved.
Description
Technical field
The present invention relates to the gear machining technology field, particularly a kind of frock of utilizing the self-centering processing diameter of axle of gear teeth face pitch cone location circular cone (right cone, arc awl) gear shaft.
Background technology
Because bevel pinion shaft exists geometric eccentricity and heat treatment deformation in system tooth operation, be a great problem that system tooth industry exists for a long time.Existing processing mode is to utilize the two ends centre bore of gear shaft to come the positioning head frame driving lever dialling the part processing diameter of axle; If but the coaxial accuracy of the pitch cone of gear and the diameter of axle is not high in existing processing mode; When the high speed rotary transmission, will produce periodic impact endurance test shock, so produce noise.
Summary of the invention
Goal of the invention of the present invention is: to the problem of above-mentioned existence; The geometric eccentricity of a kind of corrected gear to greatest extent and the diameter of axle is provided; The diameter of axle processed and the awl pitch circle of gear are remained on the same axial line to greatest extent, thereby effectively improve the bevel gear shaft flank of tooth pitch cone positioning tool of processing precision of products.
Technical scheme of the present invention is achieved in that a kind of bevel gear shaft flank of tooth pitch cone positioning tool; It is characterized in that: comprise band Morse taper shank frock body, floating type steel ball retaining ring and top; Said floating type steel ball retaining ring is enclosed within and places in the lump in the teeth groove of product to be processed front end in the groove that said band Morse taper shank frock body one end is provided with; Said floating type steel ball retaining ring is resisted against the limited step place in the groove, in the said top centre bore that is resisted against the product to be processed tail end.
Bevel gear shaft flank of tooth pitch cone positioning tool of the present invention; Its said floating type steel ball retaining ring comprises at least three steel balls with holes, steel wire and positive stops; Said steel ball with holes is evenly distributed on the circumference of steel wire; The aperture of said steel ball with holes is greater than gauge of wire, and said positive stop is separately positioned on the said steel wire, the both sides of corresponding steel ball with holes, and is at regular intervals between said positive stop and the corresponding steel ball with holes.
Bevel gear shaft flank of tooth pitch cone positioning tool of the present invention, its said steel ball with holes are resisted against respectively on the groove inwall and limited step wall at limited step place, the rectangular or obtuse angle structure of said groove inwall and limited step wall.
Bevel gear shaft flank of tooth pitch cone positioning tool of the present invention; Its said band Morse taper shank frock body is provided with quick-expansion stop pin assembly; Said quick-expansion stop pin assembly comprises housing, eye bolt and stop pin; Said eye bolt and housing connect as one and in housing, form a cavity, and the through hole that said stop pin lower end is passed on the eye bolt places in the cavity of said housing, is provided with the hole corresponding with the eye bolt through hole in said housing lower surface; Said eye bolt is provided with breach; Be provided with the spacer pin with said breach coupling on said stop pin top, in said stop pin bottom, cavity, be provided with positive stop lug boss, on the said stop pin, be socketed with elastomeric element between positive stop lug boss and the eye bolt.
The present invention is through the structural design of band Morse taper shank frock end of body groove and the cooperation that is enclosed within floating type steel ball retaining ring in the teeth groove of product to be processed end; The diameter of axle of product to be processed and the awl pitch circle of gear are remained on the same axial line to greatest extent; Revised the geometric eccentricity of the gear and the diameter of axle to greatest extent; Prevent to add the problem of tooth runout in man-hour, improved the product precision greatly; Being provided with of quick-expansion stop pin assembly prevented that effectively product to be processed from adding man-hour because cutter or emery wheel feed amount is excessive, the too fast phenomenon that causes product to be processed to skid of feed speed.
