Abstract
The invention discloses a machining method of a lathe spindle. The method adopts a complete set of technical process comprising blank selection, annealing treatment, rough machining, finish machining and surface treatment. According to the invention, the annealing treatment is performed before rough machining, so that local distortion caused by local quenching can be avoided, and the machining precision of the lathe spindle is improved; the machining method has the advantages of simple technology, convenience for operation and high precision, and has high practicability.
Description
Technical field
The present invention relates to field of machining, especially a kind of processing method of lathe spindle.
Background technology
Lathe claims again lathe, uses the workman of lathe to be called " turner ", and in mechanical processing industry, lathe is considered to the work " machine tool " of all devices.Lathe is mainly used in machining shaft, dish, cover and other have the workpiece of rotary surface, take cylinder as main, is to use a widest class lathe in machine-building and repair factory.The machinery of the rotation such as milling machine and drilling machine processing all extends out from lathe.The main shaft of lathe is the important core parts of lathe, main shaft plays the effect of transmission power in lathe, power section drives chuck by main shaft and rotates, thereby complete machined, the stationarity that main shaft turns round on bearing directly affects the crudy of workpiece, once the running accuracy of main shaft reduces, the use value of lathe will reduce, so the processing of lathe spindle is rather crucial.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
Goal of the invention: the problem produced in order to solve prior art, the invention provides a kind of easy to operately, improve the processing method of the lathe spindle of lathe spindle machining accuracy.
Technical scheme: for achieving the above object, the present invention can adopt following technical scheme: a kind of processing method of lathe spindle comprises the following steps:
(1) blank is selected materials: choose the low-carbon alloy Steel material;
(2) annealing in process: selective hardening is carried out in end, the first high-temperature heating of an end of blank, to 1150-1250 ℃, then is carried out to the low temperature aging processing;
(3) roughing: roughing is carried out on surface to foreign round, carries out the location of center hole, and surface is carried out rough turn to foreign round;
(4) fine finishining: drill through hole, fine turning outer circle, the conical surface and taper hole etc.;
(5) surface treatment: the technique that adds fine grinding by corase grind is removed the vestiges such as burr that on main shaft, machined stays, and obtains finished product after reducing its roughness.
Further, described blank shape is selected cylinder.
Beneficial effect: the processing method of a kind of lathe spindle disclosed in this invention, adopt a whole set of slab selection, annealing in process, roughing, fine finishining, surface-treated technological process, adopt annealing in process before roughing, can avoid causing because of selective hardening local deformation, improve ssupervisor's precision of lathe spindle, it is simple that the present invention has technique, easy to operate, high-precision advantage, have very strong practicality.
The specific embodiment
Below in conjunction with the specific embodiment, further illustrate the present invention, should understand the following specific embodiment only is not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
