DE3047032A1 - Setting machine for placing stones in claws - has transversely movable jaws for enclosing claws without crushing stone - Google Patents

Abstract

The setting head of the machine can be moved with its setting jaws against spring action. It is moved by a set of levers onto the open claws of the stone setting in order to slide the jaws centrally to adjoin the claws on the stone the jaws can be moved transversely on the setting head with a longitudinally guided slide sleeve in guide grooves. The jaws which are transversely displaceable in radial grooves in the socket of the setting head are connected by a swivel lamella to a rotary plate with the lamellas being connected on the one hand to the jaws and on the other to the plate.

Description

Description:

The invention relates to a device for grasping in Stone settings with inlaid gemstones using patented setting pliers .. .. ... (P 30 32 011.7).

T he device for grasping according to the main patent is characterized in that a barrel head with barrel jaws against spring action by means of lever rods Can be delivered on the open frame clamps and controlled by encompassing sensor caps for the central displacement of the barrel jaws and further advancement of the same, the barrel clamps are foldable on the gemstone.

It is the task of further training using essential elements of the main patent to simplify the delivery of the barrel jaws while being secured against crushing the gemstone during the mechanical setting process. This is the barrel head with barrel jaws against spring action by means of lever rods on the Open frame clamps can be delivered and for central displacement of the setter jaws - to apply the socket cramps on the gemstone - are the same on the barrel head with a longitudinally guided sliding sleeve that can be moved transversely in groove guides, with the in the receiving part of the barrel head in radial grooves, transversely displaceable barrel jaws via swivel lamellae are connected to a rotary plate, which slats on the one hand via pins with the barrel cheeks and on the other hand over Cones with the one above it Rotary plate are connected.

This enables a simple construction of the one provided with a sliding sleeve Fasserkopfes compared to the main patent and brings the further possibility of a Infeed limitation of the setter jaws in order to avoid crushing the gemstone. For this purpose, on the rotating plate between the ends of a resting, limited spreadable Round spring articulated an actuating lever, which to the outside in a rotary ring Manual actuation engages, which means that the further feed ir setter jaws in the radial grooves actuated by the rotating ring braking of the round spring when spreading by means of gripping between its ends Operating lever is limited.

Further details of the device according to the invention are given below illustrated and described with reference to the drawing of a preferred embodiment namely show: F i g. Fig. 1 is a partial side view of a device when grasping in section, F i g. 2 the barrel head with sliding sleeve cut open F i g. 3 a partial plan view of Fig. 2 and F i g. 4 the barrel head in perspective Exploded view of the individual parts without sliding sleeve.

As can be seen from the drawing, the device for Grasping stone settings with staples 1 inlaid gemstones 2 by means of setting pliers from a barrel head 3 with barrel jaws 4 to the staple system by means of a recess 5. The Fassert head is operated by a pivot lever 6, which on the one hand below parallel connection of a Bückholfeder 7 an eccentric lever 8 for actuation via the Sliding part 8 / engages, with its (8) pivoting in direction A by means of engagement 9 barrel head 3, which can be actuated by the pivot lever 6, is moved downward in direction B.

possibly with overload spring The barrel head 3 has a means åtift slot guide 10, 10a longitudinally guided sliding sleeve 11 with receiving part 12, which has radial grooves 13 for the transversely displaceable Fasser jaws 4, wherein the longitudinal guidance takes place in the stand part 14 and the screw part 15 the barrel head 3 interchangeable by engaging in its threaded bore 16 on the sliding sleeve 11 holds. The transversely displaceable Fasser jaws 4 are via pivot lamellae 17 with the Rotary plate 18 connected in the barrel head, which slats 17 on the one hand via pins 19 with the barrel jaws 4 and, on the other hand, via pin 20 with the one above it Rotary plate 18 are connected. On the rotary plate 18 is between the ends of the resting, limited spreadable round spring 21 at 22 with counter bearing 23 of the actuating lever 24 hinged, which (24) outwards into a rotary ring 25 for manual operation - Rotation in direction c - matures, causing the barrel jaws 4 to move over the swivel lamellae 17 after prior feeding B by transverse displacement D on the staples 1 with inserted Gemstone 2 delivered and the same (1) brought to the plant on stone 2. After creating the Fassungskrampen 1 on the gemstone 2, the further supply of the Fasser jaws 1 in the radial grooves 13 from the rotating ring 25 actuated by braking of the round spring 21 during spreading by means of actuating lever gripping between its ends 24 limited, as can be seen from Fig. 3, whereby a crushing of the gemstone 2 is avoided.

The swivel lamellae 17 consist of four passer jaws al of quarter-circular, cranked flat base corresponding to FIG. 4, which partially overlap and at the ends a respective upward or downward pin 19, 20 for engagement have in the gripper jaws 4 or the rotary plate 18. The round spring 21 consists from a flat circle spring corresponding to Fig. 4 with slots for inserting the between the rotary plate 18 at 22 and the counter bearing 23 ance steered actuating levers 24 and lies together with the turntable in a cylinder recess 2> arn Fasserkdpf 4 for the spreading limitation, as shown in dashed lines in FIG. 3.

The Fasserbacken 4 have such a recess 5 to the plant the Fasserkrampen 1 of the stone frame 2 that the after delivery at Central displacement D bring the Fasserkrampen 1 on the gemstone 2 to the system and with further delivery 3 of the barrel head 3 with sliding sleeve 11, the assenkrampen 4 on the stone edge according to Fig. 1 fold. Also in; Barrel head 3 or the sliding sleeve 11 can correspond.

the main patent can be interposed with a spring.

In addition, the gemstone setting is made with mounting clamps 1 and a shoulder 2 retained in accordance with the main patent in a jewelry recording 30, which in Richtunq E rail-guided and lockable by means of clamping lever 31 and at height F by means of Eccentric rotary handle 32 can be adjusted.
