Matthias, Schatl'hausen, Switzerland, assignor to Gieorg Fischer Aktiengesellschaft, Schaifhausen, Switzer an Filed Aug. 26, 1964, Ser. No. 392,153 Claims priority, application Switzerland, Sept. 26, 1963,
11,889/ 63 Claims. (CI. 82-14) The present invention relates to a device for parallelly guiding a templet holder on a chip-removing machine tool with copying device, in which the templet holder is arranged on lateral supporting members of a support which is tiltably journalled for adjusting the copy templet.
A tilting device for a copy templet has become known according to which the templets are arranged in a support which is tiltable about pivots mounted on the machine. The said support carries adjusting means for adjusting the templet to the desired work piece diameter. If, with such an arrangement, for purposes of adjusting the tool, large adjusting strokes, i.e. adjusting angles are necessary, the angle of inclination of the templet contour to be scanned changes with regard to the contact surface of the feeler, which may result in copying errors.
In extreme instances, the deviation brought about by the required correction may be so great that the control edge of the copy templet will be located outside the contact range of the feeler.
It is, therefore, an object of the present invention to provide a device for parallelly guiding a templet holder on chip-removing machine tools with copying device, which will overcome the above-mentioned drawbacks. 1
It is another object of this invention to provide a device as set forth in the preceding paragraph, in which the copy templet may be adjusted to a relatively large extent without the necessity of changing the angular position of said copy templet.
It is a further object of this invention to provide a tiltable templet holder which may be adjusted to two or more positions.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, inwhich:
FIGURE 1 diagrammatically illustrates an elevation partly in section through a copy lathe equipped with a copy templet holder according to the present invention;
FIGURE 2 is a perspective view of a portion of the arrangement of FIGURE 1 and, more specifically, the upper right-hand portion of FIGURE 1;
FIGURE 3 is a diagrammatic illustration partially in section of another embodiment of the present invention provided with a tiltable templet holder.
The device according to the present-invention is characterized primarily in that the parallel guiding arrangement comprises two pivot points on elements of the machine, on which pivot points two arms are tiltably journalled. These arms have one of their ends provided with a movable pivot while the same movable pivots are interconnected by a further arm which, in its turn and more specifically at one end thereof, carries a rigidly arranged templet holder. The invention is furthermore characterized in that one of the arms journalled on pivots of the machine is rigidly connected with a support carrying a fixed pivot associated with a respective arm, the said support representing an adjusting lever which is adapted to be affected by an adjusting screw.
Referring now to the drawing in detail, the copying lathe illustrated therein with a hydraulic copying device as, for instance, described in U.S. Patent No. 2,645,084,
has mounted therein a workpiece 2 rotatable on a Work means 39. The arrangement according to the invention furthermore comprises a base 8 to which is connected the machine bed 7 and two lateral walls 9 (only one of said lateral walls being visible in FIG. 1viz. the righthand one). Also visible from the drawing are parts of a hydraulic copying control including a copy templet holder 21 having connected thereto a copy templet 23, a feeler lever 25 rotatably journalled on pivot 26 on copy carriage 5, said feeler lever 25 carrying a feeler 24. When copy turning, said feeler 24 slides along copy templet 23. A control member such as a valve 29 which is displaceable relative to a stationary control edge 28 4 of the copy turning device is, through a rod 30 and a connection 31, connected to the feeler lever 25. The arrangement also comprises a pressure spring 27 acting upon control member 29. The copy carriage 5 moves along guide means 39.
The templet holder 21 is by means of pivots 20 rotatably suspended on two arms 22 (one only being visible). Said two arms 22 form a part of a support 18 which is turnable about a pivot 19 on said side walls 9. Templet holder 21 is rigidly connected to a lever arm 17 which in its turn, by means of a pivot 13, is pivotally connected to an arm 12 rotatably journalled on a pivot 11 in a U-shaped support 10. U-shaped support 10 is rigidly connected to side wall 9 and comprises an adjusting screw 16 and a pressure spring 14, which are adapted to act upon an adjusting lever arm 15 rigidly connected to support 18. FIG. 2 shows in perspective, the location of the various elements described above in connection with FIG. 1.
Operation of the embodiment of FIGS, 1 and 2 In the parallelogram-like four-joint train which serves for parallelly guiding the templet holder 21 and consists primarily of elements 12 and 17 and arm 22, each two 7 of the respective oppositely located members of the four-joint train have the same length. Since the two joint pivots 11 and 19, which are located above each other, are anchored to the side plate 9, the first member of the four-joint train is formed by the side plate 9 itself, whereas arm 22 rigidly connected to support 18 represents a further member. the pivot 11 and in view of the pivot 13 connection will continuously during tilting movements of support 18 hold member 17 parallel to the connecting line of pivots 11 and 19. As a result thereof, the copy templet 23 may be adjusted to any customary extent without a change in its angular position. This adjustment is effected by means of adjusting screw 16 acting upon adjusting lever arm 15 which is under the effect of a pressure spring 14, and also through the intervention of support 18.
Embodiment of FIG. 3
The embodiment of FIG. 3 represents a further development of the device illustrated in FIGS. 1 and 2. The pivot 11 of FIG. 1 has its equivalent in the pivot 11a of FIG. 3 but in contrast to the arrangement of FIGS.
The function of this device consists in that templet holder 38 is guided parallelly not only in the manner described in connnection with FIGS. 1 and 2 but its tiltable adjustment is effected by a suitable displacement of the pivot 11a by means of said four-joint train. In the position illustrated in the drawing, copy templet 23a can be scanned by the copy system. Copy templet 23b is in tended for a second machining operation. To this end, the adjusting device 35, which is adapted to be actuated mechanically, hydraulically, pneumatically or electrically,
displaces pivot 11a to position 11b whereby the pivot 13a moves to position 13b. As a result thereof, tiltable templet holder 38 is so adjusted that the copy templet 2312 may be scanned by feeler 24. It will be obvious for geometrical reasons that this tiltable adjustment will function also when arm 22 and thereby link 12 are not horizontal. When displacing the pivot 11a to position 11b, link 12 does not move in its longitudinal direction but parallel to itself.
It is, of course, to be understood that the present invention is, by no means, limited to the particular construction shown in the drawing but also comprises any modifications within the scope of the appended claims.
