Description

Grinding machine control The invention relates to grinding machines, in particular profile grinding machines for the execution of gearwheels, spline shafts or. Flute shank or similar grinding processes, and aims to improve Control device for the relative infeed of the grinding wheel and a workpiece, in particular to create their delivery to this. This facility should the desired dressing of the grinding wheel automatically during the grinding process allow and a material removal from the workpiece according to a required program enable.

The invention with which this object is achieved is a Grinding wheel control, in which NOcker elements, such as step cam elements, after a certain time program the engagement of a grinding wheel in a workpiece are assigned, with the identifier that the cam elements for actuating a Button and this are set up for actuating a screw device and the screw device to the relative feed of the grinding wheel and the workpiece is used during the grinding process. In a further development of the invention control means are connected to the cam elements to provide a device Carrying out the finishing of the grinding wheel in one or more stages to operate during the process and --irie relative setting of Grinding wheel and workpiece to react in order to reduce the size of the grinding wheel Compensate in the course of the finishing work.

Further features of the invention are explained in more detail with reference to the embodiment illustrated in the drawing; show it: 1 shows a grinding machine control according to FIG Invention; is the lower part of FIG on a larger scale for clarity shown; Fig. 2 is a partial axial view of a grid driving device direction. In Fig. 1, an application of the invention to a gear wheel or flute grinding machine: The grinding wheel 1, which is carried by a wheel holder 2, is set up to feed a workpiece 3 (e.g. gear or several gears or spline shafts or flute shafts), the wheel 1 and the wheel holder 2 for a radial feed movement . , Axis of the workpiece 3 and are usually, but not necessarily, arranged in a vertical direction. As indicated by the arrow, the workpiece 3 is rotated axially and relative to the grinding wheel, so that actually a transmission of the wheel 1 relative to the workpiece 3 is achieved with every rotation of the latter.

So drives one operated by a handwheel (not shown) Screw 9 a gear 10, which, when the clutch, r: ie z.8. magnetic Clutch 11 appropriately operated i: ird, a drive to the while 12 and from there over the gear transmission 13 to the -? clocking screw, 14- engaging in the grinding disk holder 2 transmits.

When the initial setting is done in this way, the clutch 11 is actuated to release the handwheel-operated worm drive 9, 10, whereby the shaft 12 then with the grid driving device, '_5 is coupled, which is put into operation for dressing the grinding wheel 1., as will be explained below.

If a work cycle of the grinding wheel 1 with respect to the workpiece 3 performed :: ird, there is an increase in infeed of the grinding wheel to the ;; ErkstUclir, Necessary for the next step, although this was done during the previous period; removed material must be taken into account.

At the dike time, the button 1) is activated by a corresponding operation of the hydraulic piston 29 is withdrawn from contact with the IJockenprofil 16a and against one. Fixed setting stop 30 brought, according to its mode of operation and, as will be explained later, ddm corresponds to the final dimension of the workpiece 3.

An axial detailed view of the ratchet drive device 15 is shown in FIG liig. <shown adjacent to the shaft 12 of the main character, advantageously, when the light 12 is actuated by the device, a corresponding operation is performed Guide screw 14 and therefore of the grinding wheel holder 2 via the gear 13 received "rird. After the disk 1 is delivered, its position corresponds with respect to the axis of the workpiece j. the final measure of the latter.

After such delivery and immediately before the return of the Workpiece 3 by means of the slider Ö to disk 1 is the hydraulic piston 29 for bringing back or enabling the spring-loaded return of the button 19 actuated in contact with the cam profile 16a, whereupon the Sciileifarbeit.sgang in accordance with the program which is carried out by the cam elements 16 in conjunction is controlled with the screw device 17.

By an arrangement with which the button 19 against the fixing stop 30 is brought, and by the resulting adjustment of the disc 1, which at an infeed operation is achieved (along with the end trunnion adjustment the latter), the grinding operation can be performed without any other Compensation for the pane infeed required is (e.g. 8. a different one than that by the Rüsterr @ itri: ir: ir.vorriciuiz --_-, 15 actually Provision), ji: änrerid dIe durc ^ @ ü: .i @ lt: s.tstop j0 intended final setting remains constant.
