Abstract
The invention discloses a technique for milling two end surfaces of a bearing support of an automobile intermediate shaft, which mainly comprises the following steps: (1) a workpiece material HT200 is selected, wherein the roughness is 12 mu m, the machine tool is a YG6 milling machine, and the cutting fluid is a common emulsion; (2) the cutting consumption is selected, the milling depth is determined, and the feed engagement is determined; (3) the pure ground standard and service life of the milling cutter are selected, wherein the maximum abrasion loss of the milling cutter tooth and face is 2.0 in the rough machining process and 0.5 in the fine machining process, the actual cutting speed and feed engagement are 0.125mm/z, the cutting speed is V=94.2m/minute, and the feed amount is 0.125mm/z; and (4) the following requirements are raised to the machine tools: the selected cutting consumption is 375mm/minute, and the milling cutters are arranged symmetrically in the cutting process. The bearing produced by the method is beneficial to stabilizing the roller and fixing the balls in the installation process, is convenient for improvement according to different automobile models and is convenient for replacement or maintenance in time.
Description
Technical field
The present invention relates to automobile technical field, relate in particular to a kind of support of bearing milling both ends of the surface technique of automobile middle shaft.
Background technology
Along with the progress of technology, in the front and Frontal offset impact process of car load, when often there is enging cabin and causing driver's shank and step space by compression to the space invasion of driving cabin, steering column mandrel makes its chest trauma evil or directly causes driver's death to driver's chest play, leg room is extruded and increases rescue difficulty, therefore collapse type tubing string is widely applied on car load, and shrinkable sliding steering jackshaft is also applied on car load gradually simultaneously.
At present, turn to transmission jackshaft mostly to be splined sleeve and splined shaft is in mating connection, spline fitted is conducive to turn to the flexible of transmission jackshaft, is convenient to plant personnel assembling and is conducive to turn to the crumple of transmission jackshaft simultaneously when there is car load collision.Client requires also more and more higher to car load comfortableness, the particularly comfortableness of handling maneuver can affect lubricated reliability because heating up and lacking lubricant but turn in the long-term use procedure of transmission jackshaft; Splined sleeve is the inner vacuum that easily forms in use, affects the slip of jackshaft, reduces the comfortableness of steering operation.
Thereby, for the support of bearing of jackshaft, the processing of carrying out two end faces need to be set, for the milling processing of this part end face, exist certain drawback, therefore, for above aspect, need to make effective innovation.
Summary of the invention
The object of this invention is to provide a kind of can minimizing accident in driver meet with dangerous degree, be conducive to firm roller, be beneficial to fixing ball when mounted, the support of bearing milling both ends of the surface technique of the automobile middle shaft being convenient to improve according to different automobile types, to solve many deficiencies of prior art.
Object of the present invention is carried out specific implementation by the following technical programs:
A support of bearing milling both ends of the surface technique for automobile middle shaft, is mainly comprised of following steps:
(1) first, choose workpiece material HT200, roughness is 12 μ m, and lathe is YG6 formula milling machine, cutter X52K slotting cutter=100mm, z=10; Cutting fluid is common emulsion;
(2) then, select cutting data, determine milling depth, determine feed engagement;
(3) select milling cutter to grind pure standard and cutter life, when milling cutter tooth knife face greatest wear amount is roughing 2.0, during fine finishining 0.5, actual cut speed and feed engagement are 0.125mm/z, cutting speed V=94.2m/min, and the amount of feeding is 0.125mm/z;
(4) lathe requires: selected cutting data 375mm/min, and during skiver, the symmetrical milling cutter of installing.
The beneficial effect of the support of bearing milling both ends of the surface technique of automobile middle shaft of the present invention is: the support of bearing parts of producing by the method can minimizing accident in driver meet with dangerous degree, be conducive to firm roller, be beneficial to when mounted fixing ball, be convenient to improve according to different automobile types, be convenient to change timely or safeguard.
The specific embodiment
The support of bearing milling both ends of the surface technique of automobile middle shaft described in the embodiment of the present invention, is mainly comprised of following steps:
(1) first, choose workpiece material HT200, roughness is 12 μ m, and lathe is YG6 formula milling machine, cutter X52K slotting cutter=100mm, z=10; Cutting fluid is common emulsion;
(2) then, select cutting data, determine milling depth, determine feed engagement;
(3) select milling cutter to grind pure standard and cutter life, when milling cutter tooth knife face greatest wear amount is roughing 2.0, during fine finishining 0.5, actual cut speed and feed engagement are 0.125mm/z, cutting speed V=94.2m/min, and the amount of feeding is 0.125mm/z;
(4) lathe requires: selected cutting data 375mm/min, and during skiver, the symmetrical milling cutter of installing.
