Abstract
The invention relates to a non-warp plane grinding method used for a thrust roller bearing ferrule. An electromagnetic non-core clamp is used as a work piece clamp on a machine tool. The work piece of the thrust roller bearing ferrule is arranged on the clamp and the work piece turns together with a grid of the electromagnetic non-core clamp. The end face of the bearing ferrule is grinded by the end face of a boring grinding wheel. A low magnetic force of the electromagnetic non-core clamp is adopted to clamp the processing ferrule plane of the thrust roller bearing ferrule so as to reduce the stress to the work piece and to reduce an elastic distortion degree of the work piece in a clamping process. Then a parallel difference and a plane degree of the grinded place can be guaranteed and the parallel difference and the warp are all less than 0.002mm. A warp distortion of the work piece is just the 1 to 2 percent of that caused by the common processing method, almost without any warp.
Description
Technical field
The invention belongs to technical field of bearing processing, especially relate to a kind of thrust roller bearing lasso flat surface grinding method.
Background technology
In the mechanical processing process of thrust roller bearing lasso, often run into this class problem, because lasso is a thin-walled parts, in heat treatment and process, easily produce distortion, when grinding lasso plane, usually adopt surface grinding machine to go to the flat surface grinding, when clamping workpiece owing to use the magnechuck clamping, stronger magnetic force can be inhaled workpiece flat by force, workpiece produces strain, after machining, along with the elimination of magnetic force, workpiece returns to deformation state again, Jia Gong workpiece warpage is more serious by this way, does not satisfy instructions for use especially for high-precision bearing parts fully.Reduce buckling deformation, just must reduce magnetic force, but the cutting force of emery wheel is very big during the surface grinding machine processing parts, reducing magnetic force can cause clamping workpiece not firm, add that may to occur workpiece in the process loosening, even safety problem appears, it is imperative therefore to seek a kind of non warping surface grinding method for angular-contact roller bearing ferrule.
By above-mentioned analysis as can be known, solve warpage issues, must consider from two aspects: the one, the clamping power of part can not be excessive, and the 2nd, cutting force can not be excessive.So need to select a kind of equipment frock that meets this two aspect simultaneously.And electric magnetic no-core to clamp folder bearing ring grinding bearing lasso inside and outside footpath be means commonly used in the bearing machining, its convenient mounting and clamping, accurate positioning also helps and raises the efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of non warping surface grinding method for angular-contact roller bearing ferrule.
For achieving the above object, the present invention adopts following technical scheme: non warping surface grinding method for angular-contact roller bearing ferrule, on lathe with electric magnetic no-core card workmanship clamping tool, thrust roller bearing lasso workpiece is contained on the anchor clamps, with rotating on the electric magnetic no-core card, use the end face of the end face of inner diameter grinding wheel by the mill bearing ring by grid.
Concrete flat surface grinding method comprises the steps:
1) on lathe, installs and the suitable electric magnetic no-core card of workpiece, will be suitable for being loaded on the electric magnetic no-core card of workpiece by grid;
2) workpiece is positioned in advance between two fulcrums of electric magnetic no-core card, an end face of workpiece is adsorbed in by the grid end face, and another end face of workpiece is higher than fulcrum 1-2mm;
3) fulcrum of adjustment electric magnetic no-core jig makes the workpiece pivot overlap with the machine tool chief axis center;
4) adjust the electric magnetic no-core clamping and touch pressure regulator voltage, make the electric magnetic no-core card produce the magnetic attraction that is suitable for grinding work piece;
5) lean on an end face of grinder part to dimensional requirement with the inner diameter grinding wheel end face;
6) repeating step 2)-5) another end face of grinding work piece, finish the flat surface grinding of workpiece.
In the step 5), grinding wheel speed 7000r/min-10000r/min, the size of each feed is 0.005-0.01mm.
The present invention utilizes electric magnetic no-core card workmanship clamping tool, can make the electric magnetic no-core card produce suitable magnetic force according to the voltage that the size of workpiece size is adjusted contact voltage regulator, in the time of can guaranteeing grinding workpiece is had enough suction, can guarantee the distortion minimum of workpiece again; End face with inner diameter grinding wheel leans on grinder part end face, and internal diameter grinding head grinding wheel diameter is less relatively, and the cutting force of generation is also less.Therefore, can use the low magnetic force clamping thrust roller bearing lasso processing lasso plane of electric magnetic no-core folder, make that workpiece is stressed to be reduced, thereby reduce the elastic deformation level of workpiece in clamping process, guarantee the parallel error and the flatness of grinding skin.With the 9124P4 bearing ring is that (highly=7mm), undulate is out of shape example after the lasso heat treatment for external diameter=150mm, internal diameter=120mm, and the deflection minimum is 0.2-0.3mm; After utilizing conventional flat surface grinding method processing, the parallel error of grinding skin and warpage are all greater than 0.15-0.2mm, and adopt this method after abrasive wheel end face is by mill, parallel error and warpage are all less than 0.002mm, workpiece buckling deformation amount is the 1%-2% that the common process method produces the buckling deformation amount, can produce warpage hardly.This shows that low magnetic does not have the method that warpage grinding plane is the simple grinding thrust roller bearing of an a kind of practicality end face.
Adjust the fulcrum of electric magnetic no-core card in this method, after making the workpiece pivot and the machine tool chief axis center overlapping, can guarantee that workpiece rotates stably, help improving machining accuracy.
Description of drawings
Fig. 1 is the clamping structural representation that the utilization electric magnetic no-core clamps folder thrust roller bearing lasso processing lasso plane on grinding machine.
The specific embodiment
Non warping surface grinding method for angular-contact roller bearing ferrule of the present invention, on lathe with electric magnetic no-core card workmanship clamping tool, thrust roller bearing lasso workpiece is contained on the anchor clamps, with rotating on the electric magnetic no-core card by grid, with the end face of the inner diameter grinding wheel end face by the mill bearing ring, this flat surface grinding method may further comprise the steps:
1. on lathe, install and the suitable electric magnetic no-core card of workpiece, will be suitable for being loaded on the electric magnetic no-core card of workpiece by grid.
A) select and the suitable electric magnetic no-core card of workpiece by dimensional requirement, be installed on the lathe;
B) select suitable for the grid size.Require: less than the workpiece external diameter, lean on the grid internal diameter greater than workpiece diameter by the grid external diameter.
C) will be loaded on the electric magnetic no-core card by grid, and start lathe.
2. workpiece is positioned in advance between two fulcrums of electric magnetic no-core card, an end face of workpiece is adsorbed in by the grid end face, and another end face of workpiece is higher than fulcrum 1-2mm.
3. adjust the fulcrum of electric magnetic no-core jig, the workpiece pivot is overlapped with the machine tool chief axis center.
Unclamp the screw of pressing fulcrum with allen wrench, constantly adjust two fulcrum upper-lower positions, the workpiece pivot is overlapped with the machine tool chief axis center, the workpiece rotation is steadily tightened the screw of pressing fulcrum at last.
