Abstract
671,257. Trueing grinding-wheels. MASKINAKTIEBOLAGET KARLEBO. March 13, 1950 [March 23, 1949], No. 6244/50. Class 60. A device for trueing the grinding wheel 5 of a profile or copy-grinding machine to the same shape as that of the tracing pin 2 is characterised in that a pivotable guiding means 18 which contacts the tracing pin 2 is connected with the trueing means .10 in such a manner that the latter is always correctly presented to the wheel profile. A pantograph 3 connects the tracing pin 2 with a work table 4 on which the trueing diamond 10 is carried through the media of a support 9 and a slide 11 pivotally connected at 30 with a dog arm 12 which is adjustably clamped in a dovetail slide secured to the work table. The guiding means is formed by a diametrical float 17 on a pin 18 pivotally mounted in a member 13 adjustably clamped to a guide 16 forming part of a table 1 which normally carries the template for the machine. The pin 18 is equipped with a control knob 22 and connected through bevel gearing 20, 21, 23, 24 with a ratio of 1 :1, universal joints 15 and a telescopic shaft 14 with a holder 26 for the rod 10. This holder is pivotally mounted in the support 9 which is connected by a pivoted link system 8 with a slideway 7 on the frame of the machine. A stock 6 supporting the grinding wheel shaft and adjustable about two horizontal and mutually perpendicular axes one of which is parallel to an edge 4' of the work table is mounted for reciprocation on the slideway 7. In order to allow the axis of reciprocation of the grinding wheel to be inclined with respect to the work table, the slideways 7, 11 are pivotally mounted about axes perpendicular to the rotational axis of the grinding wheel. In operation, the pin 2 is brought into contact with the flat 17 of the member 18 which is rotated to bring its line of contact with the pin into coincidence wth its axis of rotation and the arm 12 is adjusted with respect to the table 4 until the diamond 10 contacts one edge of the wheel 5. Trueing is now effected by moving the pin 2 across the flat 17 to cause the diamond 10 to copy the profile of the pin on the reduced scale determined by the pantograph, the member 18 being rotated during this movement to maintain its rotational axis in coincidence with its line of contact with the pin. If the grinding wheel is to be trued for the treatment of tools with side clearance, the slide 7 is pivoted about the axis parallel to the edge 4<SP>1</SP> or the stock 6 is pivoted about the axis perpendicular thereto. The support 9 may be swung into an inoperative position in which it is held by a snap spring 29.-
