Abstract
The invention relates to the field of machining, in particular to a chuck machining method. The method comprises the following steps: feeding materials; performing heat treatment of blanks; turning annealed blanks; checking the sizes and roughness of all parts of turned chucks; brazing hard alloy sleeves; performing heat treatment of the chucks welded with the hard alloy sleeves; detecting whether the phenomena of cracking, unsoldering and obvious amesiality exist in the chucks subjected to heat treatment; ,milling grooves in the head parts of qualified chuck blanks welded with the hard alloy sleeves in a radial direction; checking whether the sizes of the milled chucks meet the requirement; performing heat treatment of the chuck again; grinding inner holes of the chucks; and further grinding the peripheral surfaces of the chucks. The method is simple in machining process, facilitates manufacturing, can ensure the machining quality and dimensional precision of workpieces, prolongs the service lives of products and improves the production efficiency.
Description
Technical field
The present invention relates to field of machining, be specifically related to chuck processing method.
Background technology
Elongated precision instrument and meter workpiece, under the effect of cutting force, easily produces larger flexural deformation, and then can have influence on machining accuracy.In order to reduce the stress deformation of this kind of slender piece in working angles, in the middle part of the lathe bed of lathe or before main spindle box, all fixed chuck can be installed, this chuck plays a part support elongated workpiece, can be used for directly bearing the cutting force adding man-hour to rotate in process due to workpiece, then also should keep certain gap between workpiece and the endoporus of chuck; During excesssive gap between chuck and workpiece, the precision of processing work can be affected, when the gap between chuck and workpiece is too small, then can the fineness on disfiguring workpiece surface and precision, can produce time serious and kill phenomenon.Therefore, the gap between chuck and workpiece should control in a suitable scope, to ensure that workpiece can rotate normally in chuck and charging is vertically moved.
Use in such chuck general processing precise instrument class part, the bar diameter of processing parts is 0.5mm-2.5mm, and processing parts diameter deviation is ± 0.003mm, chuck inner bore surface roughness Ra0.1, working surface roughness Ra0.2; At present, Problems existing directly contacts between workpiece and chuck, can produce friction between the two, is easy to wearing and tearing, the concentricity of workpiece and chuck axis hole finally can be caused poor, and the precision of processing work reduces and chuck weares and teares to cause scraps.
Summary of the invention
In order to solve the problem, the invention provides a kind of process simple, be easy to manufacture, crudy and the precision size of workpiece can be ensured, increasing the service life of product, the chuck processing method of enhancing productivity.
Chuck processing method of the present invention, comprises the following steps:
The first step, blanking, obtains workpiece blank;
Second step, heat-treats blank, and anneals, and obtains the blank material that hardness is not more than 197HB;
3rd step, machines the blank after annealing, removes most of allowance, obtain the chuck of required size;
4th step, each several part size of chuck and roughness after inspection vehicle processing, satisfactoryly enter next process;
5th step, adopts the mode of brazing, due to the endoporus front end of chuck blank by the welding of carbide alloy sleeve pipe;
6th step, heat-treats the chuck blank being welded with hard alloy sleeve pipe, and anneals, and the blank hardness of stepping back controls at 197HB ~ 200HB;
7th step, whether the chuck after inspection heat treatment has cracked, sealing-off and obvious amesiality phenomenon, satisfactoryly enters next process;
8th step, to the qualified head radially groove milling being welded with the chuck blank of carbide alloy sleeve pipe, forms the multiple pawl lobes divided equally;
9th step, whether the chuck size after inspection milling meets the requirements, and satisfactoryly enters next process;
Tenth step, carries out heat treatment again to chuck, and entirety is hardened HRC50 ~ 55, then carries out lonneal, then boils chuck blank with 100 DEG C of hot water and shape for 10 ~ 15 minutes;
11 step, the endoporus of grinding chuck, makes this endoporus roughness between Ra0.2 ~ Ra0.4, and as the benchmark of chuck following process;
12 step, carries out grinding further to the outer peripheral face of chuck, obtains to carry out the outer peripheral face size of assembling with chuck clamping body;
13 step, the roughness of inspection chuck, and checks this chuck whether to meet the requirement of fitted position, satisfactoryly enters next process;
14 step, electric boring grinding machine carries out the processing of electric boring mill to the endoporus of chuck, and carries out back taper;
15 step, boils described chuck blank 1 ~ 2 hour with 100 DEG C of hot water, shapes and eliminates chuck stress;
16 step, is cut into the corresponding multiple substrates of the head pawl lobe of chuck with Linear cut carbide alloy sleeve pipe;
17 step, supports large by the endoporus of chuck and shapes, and ensures that the endoporus of chuck is greater than the diameter of workpiece;
18 step, grinds the endoporus of chuck, until reach the dimensional requirement of regulation;
19 step, comprehensive test.
Process of the present invention is simple, is easy to manufacture, and can ensure crudy and the precision size of workpiece, increases the service life of product, enhances productivity.
