Abstract
The present invention relates to an assembly method for the roll collar grinding frame of a grinding machine, which aims to improve the size accuracy of stainless steel products. In the present invention, a frame shaft initially processed but not tapered is arranged on a tank body on the head frame of a grinding machine, bearing clearance is adjusted by a screw ring, and the clearance between bearings at the front and rear ends of the connecting part of a main shaft and the tank body is regulated within 0.01mm. Then, the grinding machine is adjusted, the grinding machine longitudinally moves 135mm, and the taper is from 0mm to 0.08mm. The frame shaft is ground by a diamond plane grinding wheel, and the roll collar frame part is ground into a taper ranging between 135 minus 0.04 or 135 plus 0.04.
Description
Technical field
The present invention relates to a kind of assembly method for roll collar grinding frame of grinding machine.
Background technology
In the STAINLESS STEEL WIRE production process, mm finishing mill unit directly influences wire product quality precision as the finished product sortie, and the raising of essence being pricked the reconditioning precision of machine collars pass is very important; Collars chord position main shaft is an axle that is about 500mm; It rotates the belt transmission of leaning on motor; Utilize headstock casing to fix, use two dish bearings to regulate the bearing clearance with wire ring in the rear and front end of casing, thereby reach the precision of regulating whole chord position axle as chord position, rear end.The error of its chord position axle in rotation is: the circular runout 0.01mm of bearing.Add the mechanical run-out error 0.01mm of its work in-process own, the stack of these two errors just is reflected in the processing reconditioning error of collars, in the circular runout of 0.02mm.
Summary of the invention
The present invention seeks to overcome the deficiency of above-mentioned prior art, a kind of assembly method for roll collar grinding frame of grinding machine that improves the stainless steel product dimensional accuracy is provided.
The inventive method is:
(1) still do not have the chord position axle of tapering to be assemblied on the grinding machine headstock casing with preliminary working is intact, adjust the bearing clearance, the gap adjustment of the rear and front end bearing of main shaft and casing junction is controlled within the 0.01mm with wire ring;
(2) the adjustment grinding machine makes grinding machine vertically move 135mm, and its tapering is at 0～0.08mm,
(3) adopt the diamond flat-faced wheel that the chord position axle is carried out reconditioning, with its collars chord position part reconditioning in 135 ± 0.04 range of taper.
Grinding machine adopts cantilevered collars chord position grinding machine, and main shaft and casing junction bearings at both ends adopt thrust bearing, and model is 32217A.
The inventive method installs the semi-finished product main shaft with bearing and cooperates; Regard them as an integral body, pair roller ring stand position processes again, thus the rigging error that has occurred in having avoided installing; Main shaft only embodies the error of bearing clearance in rotation, do not have the secondary installing error.Make the error of its chord position frame axle only in rotation, embody the regulating error of bearing clearance, thereby improved reconditioning precision collars.With the grinding accuracy of collars pass by having brought up within the 0.015mm within the original 0.02mm.
The specific embodiment
The chord position axle adopts the mm of certain tapering (135-0.04) mm～(135+0.04), relies on collars and its rigid cooperating, thereby fastening.In rotation, do not produce horizontal and vertical displacement, reach the purpose of reconditioning collars.The semi-finished product grinding machine spindle of not moulding is assemblied on the grinding machine, and its left end dimensional requirement at the rear and front end running in bearings 32217A that main shaft is connected with casing, with its gap of wire ring adjustment, reaches the purpose of adjustment at 135+20mm.The use of axle partly is about 135mm; Its tapering guarantees between 134.96-135.04mm; Front-end of spindle collars chord position after the machine-shaping leans on hard the connection to fix with collars, and two bearings are adjusted, and then the grinding machine spindle left end is carried out grinding; Make its size reach 135 ± 0.04mm, reduced rigging error.After collars processed reconditioning, use the ovality of dial gauge and V-shaped rest detection collars, the not garden degree after the improvement is brought up to 0.015mm from 0.02mm, thereby has improved the service precision of pass.
Adopt commonsense method reconditioning collars chord position data cases to see the following form 1.Adopt the inventive method reconditioning collars chord position data cases to see the following form 2.
