Description

one

This invention relates to a watch industry.

Known devices for crenlepi helix to the shoe of the sentinel. Mech ism made (in (View of the desktop, provided with the elements, by them).

The proposed device differs from the known ones in that with the aim of simplifying the co-instructions and the base of the heavy element, the latter is wolf 1 in the form of two pins protruding the fret of the working table. The lateral points of the pins together with the lateral surface of the pad form a seat under the spiral.

The surfaces of the pins and pads, on which they “sprinkle”, are located at each other at an angle of 120 ° in the plane of the working table.

FIG. 1 shows schematically the described device; iHa FIG. 2 - the same, top view; in fig. 3 is a section along A-A in FIG. 2; in fig. 4 is a section along BB in FIG. 3; in fig. 5 - a block of hair (enlarged); la fig. 6 - the same, oeeipxy view.

On UNOVA 1, a desktop was mounted, made in the form of a removable circular PL1ITA 2, attached to the base with screws 3. In the center of the plate there is a finger 4, the diameter of which corresponds to the inner hole 5 of the hair pad 6. For the use of any batch of pads attached to the spirals, which are to be pushed down in the direction of the rear, they are either attached to one of the plates, but one; on a batch of pads, with na.ibnome 4, fixedly attached to the plate 2, or a plate with a set of independent removable fingers. The block 6 is precisely oriented relative to the lip 4 by two fingers 7 with eccentric heads (Fig. 6),

the rods of which are inserted into the corresponding openings of the plate 2 and are inserted into them under the action of the friction.

The coil 8 is precisely centered on the plate 2 by two cylindrical pins 9 and 10 protruding from the plate 2. Each pin rests on the rod 11 (Fig. 3 and 4) in the radial groove 12 of the plate 2. The base of the rod 1 KP1 | 13 in the recess 14, under the plate 2 in base 1.

The shoe 13 is fastened to the 15, the slide in the hole 16 of the base 1.

In another embodiment, the verticious part of the stefun 9 and 10, which are sonrikas with a helix, can be machined to obtain a sector with a central, for example, 90 °, and the self-pliers can be disposed so that the helix will come into contact with along these cylindrical sectors. Prn this. Can be used ..

Vat pins of larger diameter, which magnifies: their stability. In addition, this option facilitates the winding of the spiral 8; on the plate 2, since the contact of the spiral with the edge of the cylindrical sector ensures that it is more accurately in contact with a fully cylindrical pin.

The pressure spring 17 presses on the piston 15 and pushes it towards the micrometer 18 attached to the base 1 by means of a sleeve 19. The micrometer is provided with a locking mechanism. Both micrometers very precisely regulate the position of the pins 9 and 10 relative to the finger 4.

The rack 20 is propped onto the base 1 and supports the generator 21 for the viaaepHoro beam, with the focus system 22 containing the control elements with focusing, as well as the lock bushing 23. The corrosive bodies are located between the rack 20, the generator 21 and the optical system 22.

Block 6 has wings 24, the thickness of which is equal to the height of the helix 8. From above, both wings together have a shape close to diamond-shaped (Fig. I). Block 6 Together with vents is completely symmetrical about its axis, so that It does not disturb the equilibrium of the assembled node.

Since the hair pad 6 has a very simple form, it can be easily made with a shaped tube 1 of the circular rod. The rounded ends 25 of the wings 24 are machined during the same operation. The wing planes can be mechanically machined using parallel cutters. However, it is preferable to obtain a round base by machining on an automatic lathe, and the plane of the wings of the pad-stamping. The diameter of the center hole of the pad can be adjusted and made exactly in size. The block is also a 1M | Scale to be completely made by stamping using successive stamps.

The helix freely rests on the slab and is held in a precisely centered position with the pins 9 and 10 and the edge 26 of the pads of the hair (Fig. 6).

E | KSceitric finger heads 7 are adjusted so that the edge of the pad 26 is located in the radial plane of the plate 2, forming unchangeable angles of 120 ° with the radial planes, passing w, nm. And through the axes of the pins 9 and 10. The distance between the pin 10 and the axis of the finger 4 is controlled by the micrometer 18 and must be equal to the radius of the arc K | pa 26 plus one third of the pitch of the helix. The pin 9 is from the axis of the distance, one third of the pitch of the helix greater distance between the pin 10 and the axis of the finger. When making a spiral with the opposite direction: winding it rests on edge 27. In order for edge 27 to be located at a distance of 120 ° from the axes

pins 9: and 10, another plate 2 is used, the fingers 7 of which provide the necessary adjustment.

In plate 2, you can make another pair of holes, which would include the fingers 7 when performing a spiral with opposite winding. In doing so, pins 9 and 10 should be adjusted in reverse order.

The pins 9 and 10 would be placed along the radii at an angle of 120 ° from the edge 26. All three points formed by these two pins and the edge of the pad constantly provide the seat for the helix and its centering about the axis pads regardless of their angular positions along the inner coil of the spring. Therefore, the 1THEIFTS 9 and 10 are located in the places of the greatest distance between the block and the helix. The distance of the pins 9 and 10 from the axis depends on their angular position and pitch of the helix. In this case, the pins 9 and 10 do not cause deformation of the internal coil of the spring.

Not only the centering of the helix, but also the calibration of the dimensions of the inside coil depends on the distance between the pins 9 and 10 and the edge 26. In order to center and calibrate the inner coil, the spring is screwed by turning it around pins 9 10 and edge 26 until it contacts all three points without any deformation.

Since the thickness of the wings 25 pads is equal to the height of the spring 8, and the pad and the coil rest on the slab 2, the upper plane 28 of the spiral and the 5th wing surface are located on the same level. Before fastening the helix to the block, the generator 21 and the ontic system 22 are adjusted so that the axis of the laser beam coincides at least approximately with the edge 26. But the beam is pointed But for the edge, neither the internal end of the spring to the wing angle.

Good results have been obtained with a ruby laser,: mosquito, which is varied by manually adjusting the electrical power sources, as well as by introducing a converging optical system, aperture and optical filters between the laser output and the target. By applying a falling beam with an angle of coverage of about 9 ° and adjusting its intensity so that the coil 8 melts at about half its height, we get a weld between the coil and the shoe that meets the requirements for it.

In order to avoid accidental movement, 8 was supported by a laser beam during welding, block 29 (Fig. 3) was provided, which at least to measure the first inner spiral of the helix to plate 2 without deforming it. This unit has a central opening 30, corresponding to Clamp 1, its cylindrical opening of the pad, as well as an opening for the passage of the laser beam.

In this case, the beam impulse at the level of the edge of the helix 8 and the upper surface of the dust 25 passes inside the circular zone 31 (Fig. 6). not reaching the ro-th spiral. The diameter of this welding zone can vary from 5/100 to 40/100 iMM, depending on the pitch of the helix.

The innermost helix of the helix, which can protrude beyond the “Pads' paradise, is automatically cut off by a bundle; at a right angle to this edge. However, it is not necessary for these two surfaces to be perpendicular to the beam axis, they can also be parallel to this UN. If the outermost edge of the spring 8 is indented with the straight edge, then the laser beam will work tangentially (Fig. 6).
