Abstract
The invention provides a combined spindle capable of replacing four plug gauges. A detection gear blank hole is provided and is used for mounting a tool for machining gear blank. The problems that in the gear blank hole, the plug gauges can not be used for detection, and a manufactured gear is low in precision and low in interchangeability are solved. The combined spindle can replace four plug gauges for use, and four kinds of gear blanks with different inner diameter dimensions can be mounted on various gear machining tools respectively for machining gears. A chuck can be used for clamping the spindle for use, and ejection tips can be also used for ejecting ejection tip holes in the two ends of the spindle for use. A dimension mark is arranged at the diameter part of each spindle body, and selecting is convenient. The gears are mostly not too wide, and four spindle bodies with the commonly-used diameter being 12-40 mm are prepared so that the production demand of general factories can be basically met. A regular hexagonal prism is arranged on each spindle body, a wrench is used for dismounting the gear blank on the tool, and a vice can also be used for clamping the regular hexagonal prisms for dismounting the gear blank.
Description
Technical field
The present invention relates to a kind of mandrel.
Background technology
General factory mostly manufactures bore according to basic hole system 2 class precisions, and diameter of bore size category is many, detects endoporus cost high with feeler gauge, need to prepare a lot of feeler gauges, and general factory can not adopt.Tooth base very difficult assurance endoporus and cylindrical that each turner is processed are each time all concentric, the mandrel of manufacturing is also difficult to all guarantee the concentricity at the position of mandrel mounting teeth base and the position of chuck clamping, therefore manufactures the concentricity that gear is difficult to guarantee endoporus and reference circle.General factory process gear is mostly according to tooth base endoporus preparation mandrel, is difficult to guarantee the interchangeability of gear.Manufacturing mandrel does not mostly quench and does not grind yet, precision is low, the low easy bending of hardness, factory often because manufacture mandrel, etc. outer, the decentraction nonstandard through size of crooked, the mandrel of mandrel, mandrel cause waste product and delay production, thereby the accuracy of gear that causes processing is low, efficiency is low, affects enterprise and produce.Mandrel of the present invention can be installed respectively four kinds of tooth bases that diameter of bore is different, can use as feeler gauge, has improved precision, intensity and the utilization rate of mandrel, and a different mandrel of outside dimension can be installed respectively the different tooth base of a plurality of diameter of bores.
Summary of the invention
The present invention is to provide a kind of detection tooth base hole, and is used for the instrument that mounting teeth base processes.With solution, must not adopt feeler gauge to detect, manufacture the accuracy of gear low, the problem that interchangeability is low.The present invention solves the problems of the technologies described above the technical scheme of taking to be: combined core-axle of the present invention comprises a mandrel and a nut.This combined core-axle is coaxially set to one from left to right successively.Left outside thread spindle, the first mandrel, the second mandrel, positive six prisms, the 3rd mandrel, four-core axle and right outside thread spindle, consist of, thread spindle identical two ends in left and right are provided with center hole, and nut can be connected with left-hand thread axle or right-hand thread axle respectively.Described the first mandrel, the second mandrel, the 3rd mandrel, four-core axle successively decrease to both sides successively according to positive six prisms.The present invention can install respectively four kinds of tooth base machining gears on various gear cutting machines that internal diameter is different, can hold mandrel with chuck and use, and also can use with the top center hole that withstands mandrel two ends.The diameter position of each root mandrel is all made with dimension mark, selects conveniently.Gear is mostly not too wide, according to standby four mandrels of conventional diameter 12mm-40mm series, just substantially can meet the need of production of general factory.If run into the tooth base of different diameter of bores, can manufacture the self-defined auxiliary axle sleeve of installation, manufacture an axle sleeve easier and much quick than mandrel of manufacture, if process a plurality of gears simultaneously, can manufacture installation lengthening cover and address this problem.Mandrel is provided with positive six prisms, can utilize spanner on lathe, to dismantle tooth base, also can hold positive six prism dismounting tooth bases with vice.After quenching, mandrel processes through grinding machine mill according to basic hole system 2 class precision lower deviation go sides, hardness is large, precision is high, not flexible, not easy to wear, long service life, the present invention manufactures tooth base hole according to mandrel, can substitute feeler gauge with mandrel, detect the later tooth base hole of processing, improved machining accuracy and the interchangeability of gear.
the invention has the beneficial effects as follows:
After mandrel quenches, according to basic hole system 2 class precision lower deviation go sides, through grinding machines, grind and form, concentricity is high, precision is high, hardness is high, and a mandrel can substitute four feeler gauges and use, can detect with mandrel the standard that whether meets of tooth base hole processing.According to the outer of mandrel, through manufacturing tooth base hole, machining accuracy and the interchangeability of bore will be improved.A mandrel can be installed respectively four kinds of tooth bases that diameter of bore is different, uses the present invention to improve service life and the utilization rate of mandrel, will improve the precision of Gear Processing and the interchangeability of gear.Gear is mostly not too wide, according to standby four mandrels of conventional diameter 12mm-40mm series, just substantially can meet the need of production of general factory.Mandrel is provided with positive six prisms, can utilize spanner on lathe, to dismantle tooth base, also can hold positive six prism dismounting tooth bases with vice.A different mandrel of outside dimension can be installed respectively the different tooth base of a plurality of diameter of bores.
