Definitions

  • a machine with a container casing that can be raised and lowered to adjust the gap relative to the rotating base is already known (EP-A-0 171 527).
  • the gap width can be adjusted or adjusted to the desired size. Readjustment is highly useful or necessary if the gap width has changed during operation of the machine due to wear on the walls delimiting the gap or due to swelling or thermal expansion of the material of the container shell or of the rotating base.
  • the gap can be reduced by more than 1 mm due to thermal expansion of the container shell and in particular the container base, depending on the material properties, if the workpiece holder rises from room temperature before the machine is started up to over 80 ° C during operation due to the grinding and Friction warmed up.
  • the wear of the walls of the container delimiting the gap is also not inconsiderable, which is caused by the constant removal of the abrasive used in the workpiece holder together with the processing liquid through the gap during processing.
  • a certain gap width is of great importance in order on the one hand to prevent the workpieces from penetrating into the gap, with the result that the workpieces and the walls of the container delimiting the gap are damaged, and on the other hand too much liquid and Avoid abrasive drain through the gap.
  • the invention is therefore based on the object of avoiding the problems existing in the previously known machines with manual adjustment of the gap width, i.e. to design a machine in which a constant gap width is guaranteed without the need for constant control.
  • This is achieved according to the invention in that the lifting and lowering of the container casing relative to the floor takes place automatically as a function of the given or changing gap width, for which purpose a mechanical, hydraulic, pneumatic or electronic measuring device is provided for measuring the width of the gap, which is connected to a device for the automatic lifting and lowering of the jacket, which can be controlled by the measurement results of the measuring device in such a way that the gap width is set to a certain value or is kept at this value.
  • a desired gap width is automatically kept constant over the entire working process of the machine, which ensures that relatively thin workpieces with a dimension of less than 0.5 mm can be processed without penetration and locking of the workpieces in the Gap occurs with the result of destruction or damage to the edges of the container shell or rotating bottom delimiting the gap.
  • the aforementioned measuring device provided in the machine according to the invention can be formed by a hydraulic or pneumatic dynamic pressure gauge, which is arranged in a line which supplies the gap with a liquid or gaseous medium and which measures the dynamic pressure of this medium changing in this supply line as the gap width changes.
  • the measurement of the dynamic pressure can be more commercially available using a pressure sensor, for example an inductive or piezoresistive pressure transmitter Type (eg make "Jumo” from MK Juchheim GmbH & Co., Fulda / FRG), whereby the measured pressure or the measured pressure changes are converted into electrical signals for controlling the lifting and lowering device. Further possible measuring devices are specified in the patent claims.
  • the processing container is formed by an upper cylindrical casing 1 and a lower rotating plate-shaped base 2 which is coaxially mounted thereon and which extends with its circumferential rank to the lower edge of the casing to form a gap 3.
  • a collecting container 4 is arranged below the plate-shaped base for the processing liquid flowing through the gap 3, through the base of which the drive shaft 5 of the plate-shaped base passes through, which can be driven via the drive motor 6 arranged under the collecting container 4.
  • the container 1 rests on this pressure hose 8 with a flange 10 which is arranged on its lower edge and also projects radially and which, like the flange 7 of the lower container 4, has a depression on its side facing the hose, into which the hose engages.
  • the hose 8 Due to the weight of the container jacket 1, the hose 8 is subjected to a load acting on its upper side, which attempts to compress it from its circular cross-sectional shape shown in FIG. 3 into a flattened cross-sectional shape, also shown in this figure, with a smaller cross-sectional height. Depending on the pressure level of the hydraulic or pneumatic pressure medium in the hose, this compression can be prevented or its extent can be controlled. With the possible lifting and lowering of the container casing 1, the width of the gap 3 is changed, which gap is shown in the
  • Embodiment extends approximately at an angle of 45 ° to the container axis.
  • other angular positions of the gap with respect to the container axis are also possible, the change in the height of the container shell being made smaller by the lifting and lowering device formed by the pressure hose 8, the smaller the angle of inclination of the gap to the container axis.
  • the pressure hose 8 does not extend over the entire circumference of the container, but only over a large part thereof. It is also possible to provide a plurality of hose sections, each of which extends only over part of the container circumference, each of which is connected via a line 9 to the pressure source for supplying these sections with pressure medium. In these cases, however, a separate seal should be provided between the two flanges 7, 10 of the collecting container 4 and the jacket 1 of the processing container.
  • guide bolts 11 are provided which are uniformly distributed over the circumference of the container casing 1 and which extend axially parallel to the container axis X and are fastened with their ends to the flange 7 of the carrying device 4 by screwing. These guide bolts reach through Bores in the flange 10 of the container shell 1, whereby it is guided up and down on the guide pin.
  • the guide bolts are provided at their end located above the flange 10 with a compression spring 12, which is supported on the one hand on the head 13 of the guide bolt and on the other hand on the top of the flange 10 and to press the container jacket 1 against the carrying device 4 by compressing the hose 8 looking for.
  • FIGS. 4 and 5 differs with regard to the design and arrangement of the casing 1 and the plate-shaped bottom 2 of the processing container, the gap 3 located therebetween, the collecting container 4 serving as a supporting device for the casing, the storage and the drive of the base 2 and the leadership of the container jacket not or essentially not from the embodiment of FIGS. 1 to 3, so that the same reference numerals are used in the drawing for the same parts.
  • the device for lifting and lowering the jacket 1 of the processing container is not formed by a circumferential pressure hose, but by pressure bellows 19 arranged uniformly distributed over the circumference of the container, which in the same way as the pressure hose 8 in the embodiment according to FIGS 3 are connected to a feed line 20 for hydraulic or pneumatic pressure medium.
  • a temperature measuring device 21 which protrudes into the collecting container 4, is used to measure the gap width Has temperature sensor 22 which measures the temperature of the liquid in this container 4.
  • the measured values determined by the temperature measuring device 21 are passed on electrically via signal lines 23 to the device serving to control the pneumatic or hydraulic pressure in the pressure bellows 19 or pressure cushion.
  • the gap width is therefore not scanned directly, but is only measured indirectly via the temperature of the liquid which runs through the gap 3 into the collecting container 4, on which temperature the thermal expansion of the parts of the processing container depends, which influences the width of the gap .
  • pneumatic or hydraulic lifting cylinders 24 serve as lifting and lowering devices, which are arranged on the flange 7 of the collecting container 4 evenly distributed over its circumference and have pistons 25 projecting upwards against the flange 10 of the jacket 1 of the processing container, on the end face of which Jacket 1 rests with its flange 10.
  • cylinders are connected via pneumatic or hydraulic lines 26 to a pressure medium source which controls the supply of the aforementioned lifting cylinders 24 with pressure medium.
  • This control is carried out via a measuring device, which in this embodiment is a mechanical, in the gap movable sensor 27 is formed.
  • This sensor is displaceably mounted in the lower edge of the jacket 1 delimiting the gap 3 in the direction of the gap width in a housing 32 inserted into the jacket 1 and, with its head, may act on it from time to time until it comes to rest the edge of the bottom 2 are advanced.
  • the position of the sensor 27 in this advanced position is measured by an inductive probe 28 and displayed on a dial gauge 29.
  • the measurement result is passed on via signal lines 30 to the control of the pressure medium source for feeding the lifting cylinders 24.
  • this sensor can be briefly pushed into the edge of the rotating floor 2 at adjustable or fixed time intervals, for example every 15 or 30 minutes, during operation of the machine and can be retracted to a starting position immediately after measuring the gap width in which the Sensor does not touch the bottom edge.
  • an elastic sealing ring 31 is arranged between the two flanges 7, 10 thereof.
  • the lifting and lowering device according to the invention is of a pneumatic or hydraulic type, such as, for example, in the exemplary embodiments according to FIGS. 1 to 5, it may be expedient for organs which can be controlled by hand in the pneumatic or hydraulic feed lines to individually adjust the lifting and lowering pressure thereof Device are provided independently of the measurement results of the measuring device in order to be able to raise and lower the jacket 1 of the processing container independently of the measurement results of the measuring device.
