SU708292A1 - Device for indexing outer end of clock spring relatively to pulse jewel and straigtening termination curve - Google Patents

Description

The invention relates to the field of instrumentation and can be used to set a predetermined angle between the outer end of the clock and the impulse stone, as well as to edit the end curve.

Known devices for assembling a balance-spiral assembly, including for orienting the outer end of the spiral relative to the impulse stone, and containing a base on which a table equipped with an axis is placed, a rotatable rubber disk for orienting the spiral, a table for setting the balance, a magnifying glass, two levers for lifting the axis and the table, designed to set the balance, a support stop and a rotary punch with a head and lever (1J.

Also known are devices containing a base on which a matrix is mounted for mounting the balance-spiral assembly with holes for the balance axis and impulse stone, a rotary disk designed to orient the balance relative to the core equipped with a lever, and an arm on which a rotary punch with the head for turning the pads (2].

Known devices allow an error in the orientation of the outer end of the spiral, do not provide the ability to control the correspondence of the end curve of the spiral to the design drawing, and exclude the possibility of editing the end curve of the spiral. In addition, they have low performance.

The aim of the invention is to increase the accuracy of installation of the outer end of the spiral relative to the impulse stone and labor productivity.

To achieve this goal, the proposed device is mounted on a projector equipped with a contour drawing of the end curve of the spiral, and the IK desktop is rotatable with a limiter of the rotation angle and a central through hole, in the center of which a sleeve equipped with a groove for the impulse stone is fixed to the table a spring-loaded lever is placed, on which fixing springs are fixed, and an arm with a rotary punch is mounted on a vertical rack and spring-loaded nnym for vertical movement and simultaneous rotation around the rack.

Figure 1 shows a General view of the described device; on Lig.2 an enlarged image of the sleeve with the balance unit mounted on it

The device comprises a base * 1, on which a rotary worktable 2 is placed with a rotation limiter 3 for setting the required angle between the impulse stone and the outer end of the spiral. In table 2, a central through hole 4 is made, in the center of which, by means of a transparent insert 5, a sleeve 6 is installed, provided with a groove 7 under the impulse stone 8. 'Sleeve 6 is designed to install the balance-spiral assembly on the work table 2.

The latter is equipped with a spring-loaded lever 9, on which the springs 10,11,12 are fixed. The spring 10 is designed to clamp the impulse stone 8 to the wall of the groove 7, which eliminates the negative effect of the gap between the impulse stone 8 and the wall of the groove 7 on the accuracy of the orientation of the spiral 13 relative to the impulse stone 8.

The springs 11,12, designed to clamp the balance rim 14 to the plane of the table, ensure its reliable fixation and eliminate distortion, and the pressing force of the rim 14 of the balance to the plane of the table 2 by means of springs 11,12 is greater than the force required to rotate the shoe 15 with the spiral 13 on the axis 16 of the balance. A bracket 18 is mounted on a vertical strut 17, fixed on the base 1, on which a spring-loaded rotary punch 19 is mounted, designed to rotate the block 15 relative to the impulse stone 8. The bracket 18 is spring-loaded, with the possibility of vertical movement and simultaneous rotation around the strut 17 by guide. figure groove 20 when pressing the head 21.

The punch 19 is rotated by means of a rotary ring 22. The entire device is mounted on a projector (not shown in the drawing) equipped with a control drawing of the end curve of the spiral 13.

A central through hole 4 with a transparent insert 5 and a rotary ring 22 provide free passage of light rays from the projector.

The device operates as follows.

By pressing the spring-loaded lever 9, the fixing springs are lifted

10,11,12. A balance unit is installed on the work table 2 so that the balance axis 16 to the safety rollers in the sleeve 6, and the impulse stone 8 - in the groove 7. On the balance axis 16 is placed a pre-installed block 15 with a spiral 13. Then release the lever 9. Spring 10 acting on the balance bar, it unfolds it against the stop of the impulse stone 8 into the wall of the groove 7, and the springs'11,12 fix the balance rim 14, pressing it to the plane of the working table 2. Turn the latter all the way. Pressing the head 21, lower the punch 19 to contact with the block 15. Then, rotating the ring 22, turn the block 15 on the balance axis 16, orienting the outer end of the spiral 7, 13 according to the projection drawing. If necessary, turning 1 ‘the working table 2, the trailer makes the correction of the end curve of the spiral

13. Then they release the head 21. The bracket 18 with the punch. 19 rises to its highest position. By pressing the lever 9, the springs 10,11,12 are raised to the upper position, thereby freeing the balance. With tweezers, remove the unit from the working table 2 and lay in a container,

(54) DEVICE FOR CLASS SPIRA AND PRAVK The invention relates to the field of instrumentation and can be used to set a predetermined angle between the outer end of the watch spiral and the impulse stone, as well as to edit the end p. curves. Known devices for assembling a balance-spiral assembly, including the orientation of the outer end of the spiral relative to the impulse stone, and containing a base on which a table with an axis, a rotatable rubber disk for orienting a spiral table are known. set the balance, magnifying glass, two levers for lifting the axis and the table intended for setting the balance, the stand-rest and the rotary punch with the head and the lever 1. The devices containing the base on which the die is mounted are also known Balance-helix unit installation with holes for balance axis and impulse stone, swivel disk designed to orient the balance relative to the core equipped with a lever, and a bracket on which a rotatable punch with a head is installed to rotate the block 2. EXTERNAL END END OF CORNER PULSE CHAIN CURVE The known devices allow an error in the orientation of the outer end of the helix, do not provide the ability to control whether the end curve of the helix corresponds to the design drawing, exclude the possibility of straightening spnipsy curve In addition, they have low productivity. The aim of the invention is to improve the accuracy of the installation of the outer end of the spiral relative to the pulse stone and the productivity of labor.
