Abstract
Disclosed is a method of processing two cylindrical inner ball tracks with one time of grinding, belonging to the technical field of grind machine processing. The steps of the method includes that a location barrel is mounted on a work piece, the cross section of the location barrel is flatly and smoothly grinded by using a working face of an abrasion wheel, two supporting points of a electromagnetism centerless fixture are adjusted to ensure the two supporting points of the electromagnetism centerless fixture to support the inner circles and outer diameters of two work pieces, the separation angle of the two supporting points is 110 degrees to 150 degrees, the electric voltage of a magnetic coil of the electromagnetism centerless fixture is adjusted, enabling the two work pieces and the location barrel to keep synchronous rotating, two grooves are trimmed on the working face of the abrasion wheel, the width and depth of the two grooves are inosculated with the inner circles and outer diameters of the two work pieces well installed, a work piece shaft and the abrasion wheel are started, and then the two work pieces are simultaneously ground and processed by using the abrasion wheel. The invention has beneficial effects that two work pieces can be processed simultaneously by using the method, guaranteeing the processing quality and improving processing efficiency.
Description
Technical field
The present invention relates to the grinding machine processing technique field, relate in particular to a kind of method of processing two column internal ball tracks by one grinding.
Background technology
At present, adopt the 3M2150 cylindrical grinder of incision mill, in the special thin cylindrical bearing of processing, during raceway, once can only process a product.Add man-hour, be subjected to the radial load generation strain of emery wheel and influence machining accuracy in order to prevent workpiece, can only adopt little bite, prolonged process time, crudy is poor, and efficient is low; Emery wheel is when work, and its working face only is used a part, has reduced the utilization ratio of emery wheel.
Summary of the invention
The method that the purpose of this invention is to provide a kind of processing two column internal ball tracks by one grinding can be processed two workpiece simultaneously, and guarantees crudy, has improved working (machining) efficiency.
In order to achieve the above object, technical scheme of the present invention is as follows:
The method of processing two column internal ball tracks by one grinding comprises the steps: positioning tube 1 is installed on the workpiece spindle 7, and is with the working face of emery wheel 6 that the end face reconditioning of positioning tube 1 is level and smooth; Adjust the fulcrum 4 and the fulcrum 5 of electric magnetic no-core clamp, make two point supportings on the inner ring external diameter between workpiece 2 and the workpiece 3, angle between two fulcrums is 110 °～150 °, adjusts the voltage on the electric magnetic no-core clamp magnetic coil, makes workpiece 2 and workpiece 3 and positioning tube 1 keep rotation synchronously; On the working face of emery wheel 6, repair out two grooves, the width of groove 8, groove 9 and the inner ring external diameter of the degree of depth and mounted two workpiece are matched; Start workpiece spindle 7 and emery wheel 6, carry out grinding with 6 pairs of workpiece 2 of emery wheel and workpiece 3.
The invention has the beneficial effects as follows: this method can be processed two workpiece simultaneously, and guarantees crudy, has improved working (machining) efficiency.
Description of drawings
Fig. 1 is the schematic diagram of processing two column internal ball tracks by one grinding method of the present invention.
Fig. 2 is that two workpiece of the present invention are by the good schematic diagram of clamping.
Among the figure: 1, positioning tube, 2, workpiece, 3, workpiece, 4, fulcrum, 5, fulcrum, 6, emery wheel, 7, workpiece spindle, 8, groove, 9, groove, the width between W1, two raceways, the width of W, emery wheel.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done description in further detail:
As depicted in figs. 1 and 2, on the 3M2150 cylindrical grinder, adopt the electric magnetic no-core clamp grinding method of two workpiece of clamping, emery wheel incision mill simultaneously, the once horizontal working in reciprocating mode of emery wheel, can process two workpiece simultaneously, the method had both guaranteed machining accuracy, had improved working (machining) efficiency again, had reduced cost.
Concrete implementation step is as follows:
1) positioning tube 1 is installed on the workpiece spindle 7, with the end face of emery wheel 6 that the end face reconditioning of positioning tube 1 is level and smooth, purpose is for the end face that makes workpiece 2 can contact positioning tube 1 closely, with the positioning accuracy of assurance workpiece 2 end faces, thereby guarantees machining accuracy;
2) fulcrum 4 and the fulcrum 5 of adjustment electric magnetic no-core clamp, make two point supportings (the inner ring external diameter is the external diameter location benchmark that workpiece adds man-hour) on the inner ring external diameter between workpiece 2 and the workpiece 3, the end that workpiece 2 and workpiece 3 are combined pats whole, clean, guarantee the positioning accuracy of workpiece 3, angle between two fulcrums is 120 °, adjust the voltage on the electric magnetic no-core clamp magnetic coil, adjust to 40 volts for 20 volts during by workpiece of processing, enough big to guarantee the magnetic force that coil is delivered on the positioning tube 1, make between workpiece 3 and the workpiece 2 and can not produce relative slip, keep the rotating speed unanimity, at this moment, two workpiece rely on fulcrum 4 and fulcrum 5 and positioning tube 1 just can accurately locate; After the location, the width W 1 between the raceway of workpiece 2 and workpiece 3 is less than the width W of emery wheel 6, to guarantee two workpiece of emery wheel 6 grinding simultaneously;
3) on the working face of emery wheel 6, repair out two grooves with golden pen, be groove 8 and groove 9, the inner ring external diameter of the width of groove 8 and groove 9 and the degree of depth and mounted workpiece 2, workpiece 3 is complementary, and can not be ground to the inner ring external diameter of two workpiece when the grinding race to guarantee emery wheel 6;
4) start grinding machine, workpiece spindle 7 and emery wheel 6 begin rotation, and emery wheel 6 is horizontal working in reciprocating mode once, just can while grinding work piece 2 and the inner ring raceway of workpiece 3.
In the aforesaid operations process, owing to the radial load that workpiece 2, workpiece 3 bear emery wheel 6 simultaneously, the strain of workpiece reduces, and therefore, can adopt the bigger amount of feeding, has both guaranteed machining accuracy, has improved working (machining) efficiency again, has improved the utilization rate of emery wheel simultaneously.
