Description

Spindle taper hole grinder and its online restorative procedure
Technical field
The invention belongs to intermetallic composite coating and equipment manufacturing technical field, it is related to a kind of spindle taper hole grinder, the present invention is also It is related to the online restorative procedure to spindle taper hole.
Background technology
Current all kinds of cnc boring and milling machines have been widely used for metal-working industry, to realize the structures such as various castings, forging, weldering The thick of complicated high-precision part, half essence, finishing, lathe have milling, boring, drilling, fraising, tapping, reaming, spot-facing etc. Function;Various accessories mill-heads and rotary table are equipped with, workpiece clamped one time, multiaspect processing, a tractor serves several purposes is realized;With saving Technological equipment, shortens the Operational preparation cycle, improves operating efficiency, the advantages of reducing into production cost, obtains good economic benefit.
Although the benefit that Digit Control Machine Tool is brought is more, the fault diagnosis of Digit Control Machine Tool and maintenance are relative complex, to dimension The personnel of repairing propose higher requirement, particularly tapered bore of machine tool spindle and different degrees of abrasion occur because long-time is used, It will be deteriorated with the cone match of taper tool shanks part after spindle taper hole abrasion, so that cutter bounce change when causing the main shaft to rotate Increase, beyond the required precision of lathe so that the element size precision and geometric accuracy processed in metal cutting process Overproof, parts are scrapped, even can not normal work when serious.
Can be more and more with the such phenomenon of use time increase of Digit Control Machine Tool, if main shaft is removed into offline progress Repair process, not only wastes time and energy, and also delays normal production;And machine tool chief axis installation specification is higher, machine maintenance workman's Technical merit is uneven, if each link assembly precision is not high during reparation is finished and reinstalled, also results in main shaft Running accuracy declines.Therefore, it has been a technical problem for being badly in need of solution that tapered bore of machine tool spindle is repaired online.
The content of the invention
It is an object of the invention to provide a kind of spindle taper hole grinder, solving cnc boring and milling machine in the prior art must tear open Unloading main shaft could repair to its taper hole, the problem of influenceing normal work.
It is a further object of the present invention to provide a kind of online restorative procedure to spindle taper hole.
The technical solution adopted by the present invention is, a kind of spindle taper hole grinder, including lower slider, and lower slider is fixed on lathe On work top, lower slider is rolled upwardly through two groups of linear rolling guides and upper saddle and be connected, upper saddle and lower slider it Between be additionally provided with lead-screw drive mechanism;
Upper saddle upper surface is provided with main shaft shell, and the forward upper level in main shaft shell upper surface is provided with through hole, the through hole Two ends are respectively arranged with a bearing one, and main shaft is set with jointly in two bearings one;Front-end of spindle is coaxially connected with Mohs 2 Number taper shank, No. 2 taper shank front ends of Mohs are provided with emery wheel, and rear-end of spindle stretches out through hole and is set with primary shaft belt pulley;Primary shaft belt pulley passes through The electrical machine belt pulley drive connection of conveyer belt and motor;
It is provided with the bearing block of downslide base rear end upper surface in bearing two, bearing two and is set with leading screw, leading screw tail end is consolidated Dingan County is equipped with handwheel;Upper saddle rear end lower surface is connected with upper saddle screw, external screw thread and the upper saddle silk of leading screw circumferential surface Female screw-internal thread fit socket.
Another technical scheme that the present invention is used is that a kind of online restorative procedure to spindle taper hole utilizes above-mentioned master Axial cone hole grinder, step includes:
First, lower slider is lain against on work top, heart axle is inserted in spindle taper hole, amesdial is fixed on lathe On main shaft, gauge outfit is pressed on heart axle, starts machine tool chief axis circle table centering, i.e., turn round the grinding wheel spindle centre of gyration and machine tool chief axis Center is concentric;Lower slider is fixed with work top;
Secondly, amesdial is fixed on heart axle, and gauge outfit is pressed on spindle taper hole side bus, unclamp main shaft shell bottom The four T-shaped screws fixed with upper saddle, rotating spindle shell, while rotating handwheel, makes to be fixed on outside the main shaft on upper saddle Shell is moved forward and backward, and observes amesdial reading, and constantly adjusts the angle of main shaft shell, when making main shaft shell movable and lathe Spindle taper hole side bus is parallel, and each T-shaped screw is fastened after having adjusted;
Then, start motor, the main shaft where making emery wheel starts rotation, then starts lathe, machine tool chief axis is also begun to rotation Turn, emery wheel and tapered bore of machine tool spindle to knife by platen move and rotated handwheel to complete jointly;After the completion of knife, Handwheel is rotated to exit emery wheel;Then manually operated lathe table hand-wheel, makes platen transverse shifting, realizes laterally to enter Give;Now handwheel is rotated further by so that emery wheel is vertically moved, and completes the operation circulation of a taper hole grinding.
The beneficial effects of the invention are as follows, it is not necessary to dismantling machine tool chief axis can just repair to its taper hole, recover its geometry Precision and the accuracy of form and position, improve the reparation precision of lathe and the machining accuracy of product;Reduce the labor intensity of maintenance personal And maintenance cost, reduce lathe and stop the time, reduce economic loss caused by shutdown.
