Definitions

  • the invention relates to a grinding head for machining grooves and other recesses, in which a bearing for a rotating grinding tool and drive parts for driving the grinding tool are accommodated and which is fastened to a supporting part, the grinding head being a rod-shaped body in which the body Abrasive tool projecting on opposite sides is mounted on one end of the body and is connected from the other, drive-side end via a gear to the shaft carrying the grinding tool, the grinding head being connected to a mounting flange having a housing for receiving the drive shaft of the grinding head .
  • a grinding head is known in which the grinding tool is mounted on a shaft within the cross section of a rod-shaped body. This shaft is driven by a belt drive which extends along a rod-shaped body to the drive end opposite the grinding tool. The wetting of the belt by the grinding fluid is inevitable, which is why the life of the belt is reduced.
  • the invention has for its object to design a grinding head of the type described in such a way that it can be machined precisely in narrow bores while avoiding the disadvantages of the known grinding heads and recesses.
  • a high-frequency motor is provided as the drive part, which is coupled to a longitudinal shaft which extends through the rod-shaped body in an eccentric longitudinal bore parallel to the longitudinal axis thereof and is connected to the shaft of the grinding tool via a gear transmission with helical wheels , and the bearing, which is arranged on both sides of the grinding tool and supports the shaft of the grinding tool, receives the bearing which is more distant from the gear transmission in an arm which is fixedly arranged on the rod-shaped body.
  • the invention also includes a machine with which the use of the grinding head is optimally guaranteed.
  • a stationary support is a horizontal yoke which is firmly connected to the ends of two vertical columns and on which the grinding head is mounted so as to be displaceable in the longitudinal direction of the yoke, a height-adjustable one being guided on the columns with respect to the distance from the stationary support
  • Carrier is designed as a work table for the workpiece, which is equipped with a single or a cross slide and preferably with a dividing head.
  • the grinding head 1 shown in FIG. 1 has a fastening flange 8 on its drive-side end 7, which is integrally connected to a housing part 10.
  • the drive shaft 14 extends eccentrically through the rod-shaped body 6 and drives a grinding shaft 19 with a grinding tool 3, e.g. a grinding wheel, via a screw gear 20, of which the wheel 21 located on the drive shaft 14 is visible in FIG. 1, while the underlying wheel sitting on the grinding shaft 19 is not visible.
  • the grinding shaft 19 is in bearings 22, 23, e.g. Rolling bearings, between which the grinding tool 3 is held by a driving ring 24, the bearing 22 is mounted in an arm 25 which is fastened to the rod-shaped body 6 by means of a pin 26 and screws 27 on the rod-shaped body 6.
  • FIG. 1 further shows a workpiece 30 shown in dash-dot lines, in the bore of which the grinding head 1 is immersed and machined grooves 31, as will be explained in detail with reference to FIG. 3.
  • 2 shows some machining examples which can be carried out with the grinding head according to FIG. 1, these showing the grinding a) of a groove in a bore, b) of an outer rib, c) of a rectangular bore and d) of an outer recess.
  • the workpiece 30 shown in FIG. 3 to be machined has a bore 36 in which four grooves 37 (only three can be seen) are machined with a milling head according to FIG. 1, in which the free end 2 in FIG. 3 is from below is visible.
  • the grinding tool 3 for example a grinding wheel, not only projects downward in FIG. 1 but also laterally from the cross section of the rod-shaped body 6. This results in the possibility of two flanks 38, 39 lying opposite each other opposing grooves 37 to be machined in the same setting, only a displacement of the carriage carrying the workpiece 30 or the grinding head 1 is required.
  • the flanks 38, 39 have been machined, the workpiece is rotated through 180 °, whereupon the opposite flanks 40, 41 are machined in one setting. 2, extremely precise machining of groove flanks with a small number of empty movements is achieved.
  • a grinding machine which is equipped with the grinding head 1 described.
  • the use of such machines comes into question when grooves or other depressions or elevations have to be ground to a large extent.
  • the grinding machine 45 has a machine bed 47 placed on a base 46, e.g., on a foundation.
  • Two vertical columns 48, 49 are supported on the machine bed 47 and are firmly connected at their upper end to a horizontal support 50.
  • a grinding head 1 with a housing 10 is mounted on a horizontally displaceable carriage 51 on the support 50, the housing 10 can expediently contain the motor drive, as in FIG. 1.
  • a horizontal work table 52 is guided in height-adjustable manner in guides 53, 54.
  • a cross slide 55 is fastened on the work table 52 with a dividing device 56 with which the movements indicated by arrows can be carried out.
  • the height adjustability of the work table 52 and the lateral adjustability of the slide 51 are also indicated by arrows and shown as manually operated adjustment drives.
  • the cross slide 55 can also be designed as a single slide, since it only has to be moved in one direction with the grinding head 1 when the slide 51 is laterally movable.
  • the workpiece mounted on the cross slide 55 and to be processed with the grinding head 1 is not shown for the sake of simplicity.
  • a drive e.g. a hydraulic drive, for the height adjustment of the work table 52;
  • a control cabinet 58 is used to control and regulate the drives used on the machine 45.
  • the grinding head 1 can also be used as a milling head.
  • the gear ratios of the drives, drive parts and the further drive parts in the housing 10 must then be adjusted accordingly with regard to the different speeds during milling and grinding.
