Definitions

  • the invention relates to a method for fine grinding rings on the outer ring surface or on the inner ring surface, in particular for fine grinding roller bearing races, wherein a ring to be machined is mechanically centered in a workpiece holder and driven about its axis, and the ring surface to be machined during the grinding process of a non-contact Measurement is subjected and the grinding process is controlled and / or regulated according to the measurement.
  • the invention also relates to devices for implementing such a method. It goes without saying that the measurement values of the measurement are recorded and evaluated electrically in a suitable manner, for which purpose the modern, in particular electronic aids of the measurement and control technology offer a multitude of possibilities, including computer-based ones. The control is controlled in accordance with the specified material removal. Esp.
  • the measurement is carried out with the aid of mechanical sensors which are placed with little pressure on the ring surface to be machined and which, for. B. are equipped with a fine diamond tip.
  • mechanical sensors which are placed with little pressure on the ring surface to be machined and which, for. B. are equipped with a fine diamond tip.
  • the measurement is a contactless measurement.
  • a flow of measuring air which emerges in a free jet from a nozzle, is directed onto the surface to be processed, so that a throttle gap is formed between the nozzle and the surface to be processed (DE-AS 1 176 880).
  • Changes in the gap width of this throttle gap which are based on different distances between the surface to be processed and the nozzle, cause pressure fluctuations in the air flow which is fed via a line to the nozzle, which fluctuations are measured and evaluated in the manner described.
  • the measuring accuracy is not sufficient here and disruptive vibrations cannot be ruled out here either.
  • the invention has for its object to provide a method for fine grinding of rings on the outer ring surface or on the inner ring surface, esp. For fine grinding of rolling bearing races, with which the measurement can be carried out with great accuracy and without interference from vibrations, and a device for performing the Procedure.
  • the invention teaches that the measurement is carried out with at least two identical measuring heads, from which rinsing liquid emerges as hydraulic measuring means from at least one nozzle opening each time, and that the hydraulic measuring means is introduced into the rinsing liquid layer free of radiation, which takes along the annular surface to be machined and which forms between the measuring head and the ring surface.
  • the invention is based on the knowledge that the disturbing vibrations described in the measuring system, despite the out-of-roundness caused by the clamping, no longer occur when working in the manner described with a hydraulic measuring means and this is introduced into the detergent layer, which is on the machining ring surface, as described. This detergent layer is particularly pronounced when it comes to the fine grinding of inner ring surfaces.
  • the washing-up liquid and the measuring device mix, but this is not the case within the scope of the invention Problems arise because the rinsing liquid is used as the measuring means.
  • the measuring device provides sufficient damping in the measuring system and thereby suppresses disturbing vibrations without impairing the measuring accuracy. Surprisingly, the out-of-roundness that the rings bring with them or that is caused by the clamping does not interfere with the measuring accuracy. It is understood that the line with which the measuring means is supplied must be sufficiently rigid so that vibrations are not generated in the line system.
  • the measurements can be carried out particularly precisely if the measuring heads are arranged equidistantly over the circumference of the ring surface to be machined in order to compensate for measuring force. It is expedient to work with identically identical measuring heads. Without impairing the careful centering and without other disturbances, the measuring means can be supplied with a relatively high pressure in a measuring-force-compensating arrangement, which has a positive metrological effect. It is particularly advantageous to work with a quantity of measuring medium that is effective at the same time. In this way it can be prevented that the rings to be machined experience an inaccuracy due to heat distortion from the machining heat. In general, the quantity of measuring medium and the quantity of rinsing agent will be taken from the same pressure medium system and will also be supplied again.
  • a preferred embodiment of the invention which is characterized by particularly stable conditions from a dynamic point of view, and also in relation to the measuring system, is characterized in that three measuring heads arranged offset by 120 ° over the circumference of the ring surface to be machined are used. - The measured values can be taken from the individual measuring heads or from the measuring medium flows supplied to the individual measuring heads and evaluated individually or in an integrated manner.
  • the invention also relates to a device for carrying out the method described, with a workpiece holder for the mechanical centering and the drive of the ring to be machined, and with the ring surface to be machined and in the radial direction with respect to the ring surface to be machined, back and forth, adjustable measuring heads, characterized in that at least two identical measuring heads each have at least one nozzle opening which is designed as a feed device for the rinsing liquid which can be used as a hydraulic measuring means.
  • the device shown in the figures is intended for fine grinding rings 1 on the inner ring surface (FIGS. 1 and 2) or on the outer ring surface (FIG. 3).
  • a workpiece holder 2 for the rings 1 to be machined can first be seen, the clamping and centering taking place via mechanical clamping elements 3. 2, it can be seen that a ring 1 to be machined, which is received by the workpiece holder 2. B. is rotated via a driver 4.
  • measuring heads 5 are provided which are adjustable in the radial direction with respect to the surface to be machined. This setting can be made now and then in the radial direction, which was indicated by a double arrow.
  • a very fine gap can be set between the ring surface to be machined and the measuring head 5. 1 and 3, this gap was shown enlarged with considerable exaggeration.
  • the gap width is generally in the ⁇ range.
  • the measuring heads 5 are equidistantly distributed over the circumference of the ring surface to be machined. They each have at least one nozzle opening 6, from which a hydraulic measuring means 7 which coincides with the flushing agent emerges. It enters the measuring and rinsing agent layer 7, which has been drawn in an exaggerated thickness, without radiation. It forms between the ring surface to be machined and each of the measuring heads 5.
  • the measuring heads 5 are designed as measuring shoes, the measuring surface curvature the ring surface to be machined is adapted.
  • the nozzle openings 6 open, as shown in FIG. 2, in the measuring surface.
  • the nozzle openings 6 of all measuring heads 5 have the same diameter. They are also set up to deliver the same flow of measuring medium.
  • the measuring heads 5 can also have a nozzle tube 8 extending in the radial direction. - The procedure described above can be implemented very easily with such devices. If it is a matter of machining roller bearing races, the measuring heads 5 can be inserted into the grooves of the rings by a radial adjustment and brought into the working position.
