Abstract

The invention discloses a method for performing precision grinding to the end surface of a super-large cylindrical roller. The method is as follows: one end surface of the cylindrical roller is closely adsorbed by a magnetic pole, the rolling surface of the cylindrical roller is positioned on a positioning mechanism which forms a certain angle to the vertical line, the roller rotates in the driving manner of rotating magnetic pole adsorption, the centre line of the roller is parallel to the rotating centre line of the grinding wheel while the roller and the grinding wheel rotate around the separate centre lines; a grinding head provided with the grinding wheel performs axial movement to grind; after the end surface of the roller is grinded, the grinding head moves backward, the processed workpiece is taken down; and another workpiece to be processed is arranged, the above steps are repeated to perform the next processing cycle. Compared with the prior art, the method of the invention can be used to position the workpiece stably and accurately; and the workpiece can operate steadily during processing, the grinding wheel is convenient for dressing, and the feeding position is easy to control.

Description

Especially big cylindrical roller end face precise grinding process
Technical field
The present invention relates to the metal-cutting machining method of bearing parts, relate generally to a kind of especially big cylindrical roller end face precise grinding process.
Background technology
Especially big cylindrical roller be often referred to nominal diameter greater than 60mm with the supporting rolling element of extra large size bearing.The method grinding of manual twisting on easy device is adopted in this type of roller end face grinding, as shown in Figure 1; Or on vertical grinder the grinding end face, as shown in Figure 2.Be that cylindrical roller 2 is placed on the V-arrangement supporting seat 3 shown in the accompanying drawing 1, manually promote cylindrical roller 2 slowly near emery wheel 1, after emery wheel 1 contacted, manual rotating cylindrical roller 2 made it grinding.Be that cylindrical roller 2 is placed on the disk 4 shown in the accompanying drawing 2, press the button, start disk 4 and grinding wheel drive mitor, make it rotation, turn feed handwheel makes emery wheel 1 contact roller end face carry out grinding.Above-mentioned two kinds of methods can't make workpiece accurately, location stably, the grinding and feeding amount can not accurately be held, the no constant effective drive source of workpiece self rotation, thereby cause processed workpiece size scattered error big, the accuracy of form and position is low, the surface roughness height.
Summary of the invention
The purpose of this invention is to provide a kind of especially big cylindrical roller end face precise grinding process, solve especially big cylindrical roller in end face processing accurately, location stably, thereby control workpiece size, the accuracy of form and position and surface roughness effectively.
Purpose of the present invention can adopt following technical scheme to realize: utilize the end face adsorbed close of magnetic pole with cylindrical roller, the rolling surface of cylindrical roller is positioned on the electric magnetic no-core detent mechanism of (vertical curve relatively) lathe, its cylindrical roller rotates and adopts rotary pole absorption type of drive, roller centre line and emery wheel centre of gyration line are parallel to each other, and the center line that centers on oneself separately rotates, produce grinding by the bistrique axially-movable that emery wheel is housed, after roller end face grinds, bistrique is return, take off the cylindrical roller that processes, the cylindrical roller of clamping desire processing goes round and begins again, and carries out next fabrication cycles.
Described emery wheel is fixed on the bistrique axle by connecting screw rod.
The planform of described emery wheel is a bowl-type.
The present invention adopts the mode of electric magnetic no-core clamping to solve roller a location difficult problem is installed, accurately adjust the grinding and feeding amount by adjusting stop screw, its method of adjustment is roller and the standard component comparative result according to the examination mill, determine processing grinding and feeding amount, adjust the position of stop screw, solved grinding feed control problem.By crushing being become the taper of point of end, it is steadily sharp keen to make it grinding process, has solved in the cross grinding easy burn, roughness height, a difficult problem that the accuracy of form and position is low.
Method of the present invention, to compare the workpiece positioning stablity accurate with existing method, adds workpiece running in man-hour steadily, the crushing facility, the feed position is easy to control.The crudy contrast is as shown in the table.
Project The inventive method Existing method
Size scattered error mm 0.015 0.05
Parallel error μ m 3 30
Flatness μ m 5 30
Roughness Ra μ m 0.160 below 0.4~0.7
Surface quality Well, there is not burn Relatively poor, easily burn
By process of the present invention, can on plain grinding machine internal,, select suitable grinding tool by cylindrical roller being adopted the mode clamping location workpiece of electric magnetic no-core, process roller end face with degree of precision.
Description of drawings
Accompanying drawing 1 is a kind of schematic diagram of the method grinding cylinder roller end face that twists by hand on easy device.
Accompanying drawing 2 be a kind of on vertical grinder the schematic diagram of grinding cylinder roller end face.
Accompanying drawing 3 is schematic diagrames of grinding cylinder roller end face of the present invention.
Among the figure: 1, emery wheel, 2, cylindrical roller, 3, support and sit, 4, disk, 5, magnetic pole, 6, supporting, 7, stop screw, 8, the bistrique axle.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiments of the invention are described.
Process of the present invention as shown in Figure 3.The electric magnetic no-core detent mechanism that cylindrical roller roller 2 is placed into lathe promptly supports on 6, and 5 of cylindrical roller roller 2 one end faces and magnetic poles are contacted, and moves pre exciting switch, and cylindrical roller 2 one end faces are by magnetic pole 5 adsorbed close.Starter motor, magnetic pole axle and 8 rotations of bistrique axle, roller orders about down in company with rotating in the absorption affinity of rotating magnetic pole.Roller centre line (axis) and emery wheel centre of gyration line are parallel to each other, and rotate around own center line separately, and the bistrique axle 8 by emery wheel 1 is housed makes abrasive wheel end face contact roller end face to motion, carries out grinding.When initially adjusting test run, should adjust stop screw 7 according to the size situation of roller examination mill in good time.After roller end face ground, bistrique was return, and took off the workpiece that processes, and the workpiece of clamping desire processing goes round and begins again, and carries out next fabrication cycles.
As finish grind model with process of the present invention on the M210B grinding machine is the super-huge precision bearing roller of NN49/1250K/SPW33, this roller diameter 90mm, length 130mm.Detect processing the back roller end face, the result is as shown in the table.
