Definitions

  • the invention relates to a grinding machine for preparing the ends of a ceramic handle for garnishing to a vessel body, with a clamping device for the handle.
  • handles are cast in pairs, then dried in white and deburred.
  • the pairs of handles are then annealed and cut in the annealed state in a cutting device consisting of four adjustable cutting wheels.
  • attachment surfaces on the ends of the handles are adapted by a rotating grinding body to the outer profile of cups to which the handles are to be attached. It is necessary that the grinding wheel has a profile complementary to the outer profile of the cups. Such a grinding wheel is expensive to manufacture and often has to be dressed in order to maintain the specified profile. If the shape of the cups to which the handles are to be attached changes, a correspondingly modified grinding wheel must be inserted into the known grinding machine.
  • the invention has for its object to develop a grinding machine of the type mentioned in such a way that it can be converted with less effort for processing handles adapted to different profiles of vessel bodies.
  • the grinding machine has two separate, against the clamping device adjustable grinding units with which the two handle ends can be ground at the same time, and that the grinding units are supported by pedestals, each with its own, to the handle ends normal center plane of the handle are at least approximately normal pivot axis adjustable.
  • the grinding wheels of the machine can either have a direct grinding action on the ends of the handles or can be wrapped around by a grinding belt of known type.
  • the grinding wheels have the shape of spherical rollers.
  • bearing blocks of both grinding units are fastened to a common slide which can be advanced in the direction of the clamping device.
  • the grinding machine according to the invention can also be further developed in that a supporting body which can be pivoted about the axis of the associated grinding body is fastened to each bearing block, and the grinding bodies are each driven by a separate motor via a belt drive, which is attached to the associated supporting body via a tensioning device is supported.
  • This ensures that the motors can be arranged in an area in which they do not interfere, and the support body can be adjusted so that they do not collide with each other even if the grinding body must be brought into a position with respect to each other Grinding of handles for vessel bodies with a concave outer contour enables.
  • the grinding machine shown has a clamping device 10 with two clamping jaws 12 and 14 arranged one above the other, between which a handle 16 can be clamped, the handle ends 18 and 18 'of which are to be ground.
  • the handle 16 is symmetrical with respect to a central plane A, which corresponds to the mold division plane of a casting mold in which the handle 16, possibly with other identical handles, has been cast.
  • the central plane A is horizontal.
  • the clamping device 10 can be arranged together with several identical clamping devices on a conveyor, for example on a turntable.
  • the grinding machine also has a stationary housing 20 in the example shown, from which two horizontal piston rods 22 protrude in the direction of the clamping device 10.
  • the piston rods 22 each belong to a pneumatic piston-cylinder unit of the usual type arranged within the housing 20 and together carry a slide 24 which can be moved back and forth in the direction of the double arrow B shown in FIGS. 1, 2 and 4.
  • the carriage 24 carries two grinding units 30 and 30 'of the same type, which are arranged mirror-symmetrically to one another and, apart from the fact that they participate in all the movements of the carriage 24, are independent of one another.
  • Each of the grinding units 30 and 30 ' has a bearing block 32 or 32' with a foot 34 or 34 ', which has a transverse slot 36 or 36'.
  • a longitudinal slot is formed in the slide 24 under the transverse slots 36 and 36 '.
  • a clamping screw 38 or 38 ' extends through each of the transverse slots 36 and 36' and the associated longitudinal slot. It is thus possible to clamp the bearing blocks 32 and 32 'on the slide 24 at different distances from one another and in different ways, each pivoted about a vertical pivot axis C or C'.
  • a grinding body 40 or 40' is mounted on an axle bolt 42 or 42 ', which defines an axis of rotation D or D' lying in the central plane A.
  • the grinding wheels 40 and 40 ' are smooth, slightly spherical rollers made of steel, which are each mounted on a roller bearing 44.
  • On each of the axle bolts 42 and 42 ' there is also a support body 46 or 46 'pivotally mounted about the associated axis of rotation D or D'.
  • Each of the supporting bodies 46 and 46 ' has the shape of a vertical plate with a further bearing bolt 48 or 48' arranged parallel to the associated axle bolt 42 or 42 ', on which a rocker 50 or 50' is pivotably mounted in a vertical plane is.
  • Each of the rockers 50 and 50 ' carries a motor 52 or 52', for example a rotary vane motor which can be operated with pressure oil, with a drive roller 54 or 54 'which is carried out by a commercially available grinding belt 56 or 56' with the associated grinding body 40 or 40 'is connected and drives it.
  • a bolt 58 or 58 'parallel to the associated bearing bolt 48 or 48' is fastened, on which a tension spring 60 or 60 'of the Form of a clothespin spring is stored.
  • the tension springs 60 and 60 ' are supported with one leg each on a pin 62 or 62', which is fastened to the associated support body 46 or 46 ', and press with a second leg against the associated rocker 50 or 50'.
  • the bearing blocks 32 and 32 'each have an arcuate slot 64 or 64', the center of which lies on the associated axis of rotation D or D ', and through which a clamping screw 66 or 66 screwed into the associated support body 46 or 46' 'extends.
  • the grinding machine is set up for grinding the handle ends 18 and 18 'of a handle 16 which is to be attached to a cylindrical vessel body.
  • the two grinding units 30 are accordingly and 30 'arranged symmetrically with respect to a vertical plane of symmetry E of the grinding machine, in such a way that the axes of rotation D and D' of the grinding bodies 40 and 40 'lying in the central plane A are aligned with one another.
  • the two support bodies 46 and 46 ' are arranged identically, for example - as shown in Fig. 2 with full lines - such that the axes of rotation of the drive rollers 54 and 54' in the Center plane A and thus the grinding belts 56 and 56 'extend horizontally.
  • both grinding belts 56 and 56 ' can be maintained if the grinding machine, as shown in FIG. 4, is set for grinding the handle ends of a handle which is to be attached to a vessel body 68 with a convex outer profile.
  • the bearing blocks 32 and 32 ' are pivoted about their pivot axis C or C' in comparison with the arrangement according to FIGS. 1 to 3 in such a way that the support bodies 46 diverge.
