Definitions
- the invention relates to a method for back grinding of the cutting teeth of taps, thread formers and similar tools according to the features a to d of claim 1.
- the term "cutting tooth” should also include the profile former of the thread formers.
- a device suitable for this purpose in which a control shaft constantly rotates in the same direction.
- two identically designed control discs are provided with cams.
- the cams of the two control discs are offset by 180 degrees to each other.
- At each of the two control discs is located on a Abgriffsrolle, which are coupled together via a parallelogram lever linkage.
- the scanning movement of the tapping rollers is transmitted via an additional lever linkage to an eccentric mounting of the grinding spindle.
- the eccentric bearing of the grinding spindle is rotated, so that a rotating grinding wheel rests more or less strongly on the tool to be ground.
- control cams may be formed on the control roller, wherein their number corresponds to the number of cutting teeth on the tool to be ground.
- a special lifting device is provided.
- gearbox with change wheels is required, which are to be exchanged as needed against each other. The disadvantage of time-consuming remodeling and replacement processes in connection with the storage of high-precision replacement parts thus remains even in the machine according to DE 29 52 610 C2.
- the invention is based on the object to improve the known from the prior art method such that a low-inertia control is possible and that without the time-consuming replacement and costly storage of high-precision control parts the formation of different relief-contours with different dimensions short processing time is possible.
- the scanning of the control contour takes place in a rotating oscillatory movement.
- a scanning is provided with back and forth rotation over a limited circumferential angle of the control contour for each cutting tooth. This oscillating scanning only over a limited section of a smooth and continuous control contour avoids the lifting of a scanning member with the associated risk of rattling or vibration.
- Control contour represents a first possibility for defining a particular relief or undercut contour for a cutting tooth.
- Another Design possibility is that the rotational speeds of the rotating scanning movement and the tool are in a certain relationship to each other. For example, a small peripheral portion of the control contour can be scanned slowly, or a larger portion of the peripheral contour can be scanned at an increased rate. Depending on a different undercut contour on the cutting tooth will come about, the undercut contour can be done in one or more passes.
- the rotational speeds of the rotating scanning movement and of the tool are operationally variable.
- the operator of a particular grinding machine can therefore select a specific speed ratio before starting production and set his machine accordingly, the speed ratio and the speeds are freely programmable. In this way, multiple variation possibilities for the undercut contour are given with a single control contour in the machine.
- control contour of the rotational body in the manner of a collective curve comprises the initial values for numerous possible undercut contours. To achieve a certain undercut contour, it is thus only necessary to define a certain peripheral portion of the control contour in which the scan is to take place. For each cutting tooth to be looped, only a rotating reciprocating movement in this selected section of the control contour has to take place.
- the rotating body can be fixed and with a rotating light source or magnetic on his Scope be scanned.
- the controlling rotary body is designed as a rotating control disc with an effective as a control contour circumference in the manner of a control comb.
- Such a control comb is thus a long-drawn control cam, which has stored the various possibilities for the design of the undercut contour (control curve).
- a limited angle of rotation is selected from the control comb.
- This control comb can preferably be scanned mechanically, but in principle also optically or electronically.
- the invention also relates to a grinding machine in the manner of a universal round / non-circular grinding machine for carrying out the method according to claims 1 to 5.
- a grinding machine is provided, which has the entirety of the features specified in the claim 6 ,
- Clamping device for the tool to be looped contains. What is essential is always the coordination between a certain area of the Control comb on the control disk, the rotational speeds of the control disk on the one hand and the tool on the other hand with regard to the desired special undercut contour.
- Figure 1 is a view from above of a grinding machine for carrying out the method according to the invention.
- FIG. 2 shows the principle of scanning as it is carried out according to the invention.
- Figure 3 illustrates the relationship between the number of cutting teeth and the grooves on a tap.
- the machine bed 1 also carries a grinding table 5, which in its longitudinal direction - as usual - is adjustable (Z-axis).
- a movable support member 6 which is additionally adjustable on the grinding table 5 perpendicular to the axis Z, ie in the direction of the usual X-axis.
- the support member 6 carries the workpiece headstock 7 and the tailstock 8, between which, for example, a tap or a similar tool 9 is clamped.
- the tool 9, which arises here only, is in this. Case at the same time the workpiece.
- the tool 9 thus also extends in the Z-axis and is simultaneously rotated about its longitudinal axis, the usual C-axis controlled.
- the rotational movements of the tool 9 and the grinding wheel 4 and the feed movement of the grinding wheel 4 are matched to the tool 9, so that the desired movement in the direction of the grooves 17 and cutting teeth 16 is achieved.
- FIG. 2 explains the principle of the control. It is a control disk 11 is provided with a control comb 12 which is rotatably mounted and is offset by a low-inertia high-precision drive in a rotating oscillation movement. The oscillation takes place via a freely selectable, larger or smaller angle of rotation, which is designated ⁇ in FIG. In analogy to the usual axis designations during the grinding process, the axis of rotation of the control disk 1 1 is designated A.
- the contour of the control comb 12 is scanned by a scanning device 13, which can operate mechanically, optically or electronically and the sampling signal obtained via a
- Signal line 14 transmits to the already mentioned electronic control device 10.
- Feed movement of the grinding wheel particularly advantageous.
- the changing direction of rotation of the control disk 11 is designated by the direction of rotation arrow 15.
- a certain angle section ⁇ is selected from the control comb 12 which best corresponds to the desired undercut contour of the cutting tooth 16.
- the back grinding of the cutting teeth 16 then takes place synchronously with the scanning of the selected angle range ⁇ on the control comb 12.
- Another design option is that the sampling can be done at different speeds.
- a strongly changing undercut contour can be achieved, for example, by scanning a larger angle range ⁇ at a higher speed; as well, a rather “quiet" course of the undercut contour is achieved by slowing down a smaller portion
- the grinding wheel 4 reaches the end of the cutting tooth 16 and passes into the groove 17 between the cutting teeth 16, also the scanning of the angular range
- the initial position of the tool 9 and the grinding wheel 4 is restored, and the control disk 11 changes its direction of rotation and also returns to the home position, and the process is repeated for the next grinding tooth 16.
