Definitions

  • the invention relates to a device for grinding and lapping sealing surfaces in sliders and the like in situ or in the workshop, with a base plate which can be fastened to the housing of a slider or the like, a drive and a rotatably mounted tool plate which is connected to the drive via a support element and is coupled via a transmission element, the support element being supported in a height-adjustable and detachable manner on the base plate by means of a guide piece which is pivotable about a swivel axis running transversely to the longitudinal axis of the support element and essentially transversely to the axis of the tool plate, and with the guide piece one end of which is transverse to the swivel axis extending rocker is rigidly connected, the other end of which is coupled to an actuator which is adjustably supported on the base plate and enables adjustment of the contact pressure of the tool plate in the direction of the surface to be machined.
  • Such devices are used in particular to grind and lapping sealing surfaces in valves, slides, valve disks, slide wedges, slide plates, flanges, pump housings, etc. in their installed position. In this way, signs of wear and deposits on these surfaces are eliminated without the workpieces in question having to be removed from the respective system and thus these systems having to be dismantled.
  • the object of the present invention is now to avoid the disadvantages of the previously known devices of the type mentioned at the outset and thereby to create a device which is as simple as possible and with which the planicity of the surfaces to be processed can be reliably achieved in a relatively short time.
  • the pressure can be set that is required to correct the existing surface profile. It is then necessary to set a load or deformation which indicates a lower value on the measuring device with a surface that is inclined radially inwards or a higher value when the surface is inclined radially outwards than when the previous machining process was completed.
  • the measuring device therefore does not indicate the contact pressure that acts directly on the tool plate, but it enables simple means to bring about a controlled increase or decrease in this contact pressure, which is necessary to achieve the required planicity.
  • the device according to the invention can also be designed such that a measuring device is provided on the rocker.
  • the device according to the invention can also be designed such that the measuring device comprises at least one strain gauge.
  • the device according to the invention can also be designed such that the measuring device comprises a precision dial gauge with a stylus that receives a deformation.
  • the device according to the invention can also be designed such that the measuring device is connected to a digital display via a computer.
  • the device according to the invention can also be designed such that the effective surface of the tool plate is tapered, with its radially outer edge protruding furthest from a surface to be machined. Such an inclination of the effective surface of the tool plate leads to an increase in the contact pressure deforming the effective surface in the direction of planicity.
  • the device according to the invention can also be designed such that the effective surface of the tool plate is formed by freely rotatable cylindrical machining elements, the bearing axes of which converge in the direction of a surface to be machined.
  • the time-consuming use of feeler gauges can be avoided. The result is faster work and a more reliable result.
  • This tool plate can also be used in connection with an adapter via which a lapping disk or the like can be driven by a drilling machine.
  • the contact pressure can be determined in a conventional manner according to the spring travel or recorded via piezo elements and displayed digitally.
  • the device according to the invention can be designed such that the clamping piece is guided in the guide piece and cooperates with a height stop of this guide piece. This results in a simple possibility, after removal of the support element with tool plate and after measuring the machined surface, to bring the tool plate quickly and exactly back into the previously assumed machining position.
  • FIG. 1 and 2 show a slide housing 1 with an annular sealing surface 2.
  • the sealing surface 2 occurs twice in the housing 1 shown. 1, 2, a tool plate 3 engages on the sealing surface 2 located on the right there.
  • the tool plate 3 is rotatably mounted on the lower end of a support element 4, which is formed by two tubes 5. At the upper end of the support element 4 there is a drive 6, which drives the tool plate 3 via a transmission element, which is not shown and runs through the tubes 5.
  • a clamp 7 On the tubes 5 is a clamp 7, which is provided with a handle 8.
  • a clamping screw 9 By means of a clamping screw 9, a clamping element 10 can be pressed against the clamping piece 7 in order to fix it on the tubes 5 at the desired height.
  • the clamping piece 7 is guided in the embodiment according to FIGS. 1 to 4 in a guide piece 11.
  • the clamping piece 7 can be fixed in a U-shaped guide 13 by means of an adjusting screw 12.
  • the guide piece 11 has in its lower region a height stop 14 which has a pin 15 which engages in the lower end of the clamping piece 7 and thus fixes the clamping piece 7 in the desired position on the guide piece 11.
  • a lever-like rocker 16 adjoins the guide piece 11 in one piece.
  • the component formed from the guide piece 11 and the rocker 16 can be pivoted about a pivot axis 17 which runs transversely to the longitudinal axis 18 of the support element 4. It also extends transversely to the axis of the tool plate 3.
  • the component consisting of the guide piece 11 and the rocker 16 can be displaced and adjusted in the direction of the pivot axis 17 by means of an adjusting screw 19.
  • the pivot axis 17 is mounted in two cheeks 20 which run parallel to one another and which start from a base plate 21.
  • This base plate 21 is provided with openings 22 which simplify the connection of the device to a flange 23 of the slide housing 1.
  • FIGS. 5 and 6 differs from the previously described embodiment only in the features described below.
  • a clamping piece 35 is provided which engages in a guide piece 36. Both elements are dovetailed together.
  • a clamping screw 37 fixes the clamping piece 35 in the desired position on the guide piece 36.
  • a base plate 21 and a rocker 16 connected in one piece to the guide piece 36 are provided seen that can be adjusted via an actuator 28.
  • a holder 38 is rigidly connected to the guide piece 36 and carries a precision dial gauge 39.
  • This dial gauge 39 has a button 40 which engages the rocker 16 and registers deformations of this rocker 16 which are essentially proportional to the load on the rocker 16 and thus the contact pressure of the tool plate 3.
  • the tool plate 3 according to the invention is described in detail. It has an eccentric bore 41 and is star-shaped. It has six radially extending guide slots 42 evenly distributed over the circumference, in each of which an arm 43 can be moved and then locked in the desired position. Each arm 43 carries at its radially outer end a grinding head 44 which can be freely rotated about an axis 45. This axis 45 is ball-bearing. As particularly shown in FIGS. 8 and 9, the tool plate 3 extends in the area of the guide slots 42 in the direction of the grinding heads 44. The angle of inclination of the slots relative to the surface 46 of the tool plate 3 corresponds to the angle. The axes 45 of the grinding heads 44 are inclined by the same angle with respect to the axis of the tool plate 3.
  • both the sealing surface shown on the right in FIG. 1 and the sealing surface shown on the left can be processed.
  • the drive 6 is switched off.
  • the value displayed on the measuring device 32, 39 is recorded.
  • the tool plate 3 with the supporting element 4 and drive 6 is removed.
  • the processed area is now checked with a straightedge. It is determined whether a higher or a lower contact pressure has to be used in the next processing phase to achieve planicity.
  • the tool plate 3 with the associated parts is reinstalled.
  • the on the measuring device 32; 39 previously determined value is then increased or decreased in accordance with the required pressure change.
