Improvements in Grinding Machines
|
Sydney Herbert March |
, England |
Abstract:
In a circular grinding machine of the type in which the work v is carried on a reciprocating table w past the rotating grinding-wheel d, and the machine is driven by a self-contained motor k, all the shafts and gearing for driving the work are mounted on the outside of the machine so as to be readily accessible. The gearing for driving the work comprises a belt drive from the motor to a spur-wheel n, which gears with a wheel o mounted on a shaft p. supported in a bearing a<1> upon the machine frame, and in bearings in the work table. Upon one end of the shaft p is a mitre-wheel p<1> gearing with a mitre-wheel q<1> on the lower end of a vertical shaft q, upon the upper end of which is a mitre-wheel q<2> gearing with a mitre-wheel r<1> on a rotary swing arm r, which may be moved forward with the adjustable headstock b as required. At the other end of the swing arm is a mitre-wheel r<2> geared by a train of wheels to the rotating face-plate. |

Abstract:
A cambered surface on a roll c is produced by tilting a grinding-wheel y by means of an inclined straight-edged bar and link motion about a shaft e as the wheel is fed axially. The grinding-wheel is mounted on a head x slidable in a base d pivoted on the shaft e to a slide b traversing a bed a. On the slide b are mounted cheek plates m carrying levers j, k connected by a lever i adjustably carrying at its lower end a bowl h contacting with the underside of an adjustable straight-edged inclined bar f mounted on the bed a. The lever i has a vertically grooved extension p straddling a roller g on an arm r pivoted to the cheek plates. The arm carries adjustable stops t, u coacting with the base d. An extension v of the lever indicates the position of the slide b. For parallel grinding both stops are withdrawn, and for concave and convex grinding respectively the stops a and t are set to contact with the bed d when the slide b is in mid-position. Movement of the slide to either side of the mid-position causes an arcuate movement of the extension p and the stop carrying arm r. |

Abstract:
A grinding machine of the type in which a predetermined fall in the grinding wheel motor current produces an infeed of the grinding wheel relative to a workpiece until such reduced current is increased and restored to a predetermined value includes circuit means adapted to control the longitudinal traverse of the grinding wheel relative to the workpiece in response to such an increase in current. Thus, with a workpiece such as a roll has been worn in the middle there is a gradual fall in the grinding wheel motor current as the wheel traverses from the end of the roll to the middle of lesser diameter; when the current has fallen a predetermined amount the control circuit operates causing the wheel to move further in towards the workpiece thus producing an increase in the load current. This increase in current is utilized to stop the longitudinal traverse of the wheel, and then to reverse the direction of traverse. The full sequence of operations required to control the traverse of the wheel first to grind the tailstock portion of the roll and then the workhead portion, whilst maintaining the load on the grinding wheel substantially constant, is described in the Specification with reference to Figs. 1 to 4 of the drawings (not shown) which depict a suitable relay circuit for effecting the desired control. |

Abstract:
A roll grinding machine includes a control circuit having a first selector switch adapted to cause a predetermined degree of grinding selected from a plurality of predetermined degrees of grinding and a second selector switch adapted to cause grinding to a further predetermined degree additional to the said predetermined degree the arrangement being provided so that when workpieces such as a pair of rolls are reconditioned by the machine the first roll can be matched with the second roll which requires to have a predetermined diameter relationship with the first. Thus, in operation and with No 1 roll in position, the first selector switch is set to " No. 1 "; a preset number of rough grinding strokes determined by a first counter are then effected, followed by semi-finish and finish grinding stages. For the second roll, the first switch is moved to " No. 2" position and a rough grinding is effected for a smaller number of strokes, determined by a second counter, than for the first roll. The second roll is then measured to establish how much more material remains to be removed to bring the roll diameter to within the required dimensional tolerance relative the first roll, and the second selector switch is adjusted accordingly; the necessary additional rough grinding strokes, semi-finish strokes and finish strokes are then effected automatically. A suitable switching circuit is described in the Specification with reference to Figs. 1 to 4 (not shown). |
