Definitions

  • the invention relates to an NC-controlled cylindrical grinding machine for external and internal grinding with a machine body with longitudinal guides; a workpiece holder with a workpiece headstock on a first longitudinal slide which is guided by the longitudinal guides; with an external grinding device with an external grinding support and with an internal grinding device with a cross slide and a second longitudinal slide.
  • a machine is known from DD-A-84 808.
  • the grinding wheel for internal grinding is located on the second longitudinal slide, which in turn is attached to the internal grinding cross slide as a short-stroke longitudinal slide.
  • the first longitudinal slide with the workpiece is fed to the internal grinding cross slide, the short stroke longitudinal slide executes axial oscillations to make the grinding process more uniform.
  • outer and inner surfaces of the workpiece can only be ground separately from one another at two different, spatially distant positions of the first longitudinal slide.
  • the outer and inner surfaces of the workpiece are created by various guides, which causes non-parallelism and errors in the workpiece surfaces.
  • the operation of the known machine is slow and cumbersome due to the separate infeed for external and internal grinding and the impossibility of grinding workpieces with conical and cylindrical surfaces in one operation, and a changeover to a different type of workpiece generally requires extensive manual intervention .
  • the invention has for its object to design the cylindrical grinding machine of the type mentioned in such a way that it is quick and accurate, with workpieces with cylindrical and conical surfaces to be machined with one clamping and the changeover to other workpieces should be simple.
  • the second longitudinal slide is arranged on the longitudinal guides of the machine body, the internal grinding cross slide being mounted on the second longitudinal slide, that a rotatable plate is located between the first longitudinal slide and the workpiece headstock , and that the external grinding support has a device for axially positioning the machined workpiece.
  • Devices for axially positioning the workpiece are also known in the general prior art, but are mounted on a work table or the machine base of the cylindrical grinding machine, as a result of which an additional controlled coordinate is required for advancing the pushbutton of the device with respect to the workpiece axis.
  • the machine according to the invention has the advantage that the inner and outer surfaces of the workpiece can be machined simultaneously by the delivery of the internal grinding device to the workpiece.
  • this infeed takes place on the same longitudinal guide as the displacement of the workpiece for external grinding, high accuracy of the workpiece surfaces can be achieved.
  • the rotatable plate on the longitudinal workpiece slide enables automatic machining of various surfaces, especially if both conical and cylindrical surface sections are present, without manual intervention being necessary.
  • the attachment of the device for axial positioning on the external grinding support makes an additional controlled coordinate unnecessary, which in turn increases the accuracy of the work of the machine.
  • workpieces of various types can be processed automatically on the cylindrical grinding machine according to the invention without manual adjustments, the kinematics of the moving machine parts being very simple.
  • a left longitudinal slide 2 and a right longitudinal slide 3 are mounted on the longitudinal guides of a machine base body 1 (FIGS. 1 and 2). These can be set in motion along the body 1 with the aid of two mechanisms 4a, 4b of the same construction.
  • the rigid attachment and detachment of the rotatable plate 5 on or from the left longitudinal slide 2 is carried out by two hydraulic locking cylinders 7.
  • a headstock 8 with a spindle 9 is rigidly attached, at the front end of which a chuck 10 with manual, hydraulic or other type of actuation for attaching a workpiece to be machined 11 is arranged.
  • a dressing device 12 for dressing the circumference and the end face of an outer grinding wheel 13 is mounted on the headstock 8 at the level of the axis of the workpiece 11 in the manner of a console.
  • a spindle unit 16 for internal grinding is mounted, which carries a spindle 17 for internal grinding.
  • the spindle 17 can be arranged either parallel to the axis of the machined workpiece 11 (FIG. 3) or at an angle a (FIG. 4).
  • a linear measuring system 18 is attached to the lateral surface of the right longitudinal slide 3 and is provided for a photoelectric measurement of the displacement of the cross slide 14, to which a slider 19 is rigidly attached.
  • a protective shield 23 is rigidly mounted on the longitudinal guides of the body 1 and extends through cavities formed in the two longitudinal slides 2 and 3.
  • a support 27 is fastened to the rear part of the body, on the upper part of which, perpendicularly or at an angle of 60 ° with respect to the axis of the workpiece 11 to be machined, transverse guides 28 are fastened, on which an external grinding support 29 with a device 30 is attached to the cross feed of the outer grinding wheel.
  • a spindle unit 31 for external grinding and a device 32 for axially positioning the workpiece 11 to be machined are mounted in the front part of the support 29, a spindle unit 31 for external grinding and a device 32 for axially positioning the workpiece 11 to be machined are mounted.
  • the spindle unit 31 can be mounted on the support 29 in two positions: vertically or at an angle of 15 to 20 ° with respect to the transverse guides 28.
  • the spindle unit 31 is arranged for external grinding at an angle of 15 to 20 ° with a vertical arrangement of the Cross guides 28 with respect to the axis of the workpiece 11 to be machined to allow simultaneous grinding of the cylindrical surfaces and the end faces.
  • An NC control system 33 and a control cabinet 34 are attached to the left part of the body 1.
  • the position of the rotatable plate 5 for grinding cylindrical surfaces is fixed by a rear adjustable stop 35 and the position for grinding conical surfaces by a front adjustable stop 36.
  • the workpiece 11 to be machined is automatically positioned axially, the device 32 for axial positioning being in the working position at the level of the axis of the workpiece 11 to be machined.
  • the support 29 for external grinding is shifted along the axis X1 to the workpiece 11 to be machined until the sensor of the device 32 reaches a programmed dimension A for the corresponding end face (FIG. 5).
  • the left longitudinal slide 2, which was in the left end position up to this point for fastening the new workpiece 11 to be machined, is shifted to the right along the axis Z1 until a touch signal is emitted by the device 32.
  • the outer cylindrical surfaces and end faces of the workpiece 11 (FIG.
  • the grinding of the inner cylindrical surfaces and end surfaces of the workpiece 11 can be carried out in two ways: In the first case, a movement of the right longitudinal slide 3 along the axis Z2 only serves to feed the inner grinding wheel 22 into the working position, the dressing and one Oscillation during internal grinding.
  • the inner grinding is carried out by the inner grinding wheel 22 by moving the cross slide 14 along the axis X2 and moving the left longitudinal slide 2 along the axis Z1.
  • the grinding is carried out by longitudinal movement of the right longitudinal slide 3 and movement of the cross slide 14 after the left one Longitudinal carriage 2 has brought the workpiece 11 into the working position.
  • the outer grinding wheel 13 is in the rear end position.
  • the end face and the circumference of the outer grinding wheel 13 are dressed by the dressing device 12 during movements along the axes X1 and Z1 (FIG. 10).
  • the end face and the circumference of the inner grinding wheel 22 are dressed by the dressing device 26 after it has been rotated into a working position by a hydraulic device 37 during movements along the axes X2 and Z2.
