Description

one

The invention relates to assemblies with possible finishing operations and can be used in the production of time n-riors with a shift stroke.

Known machine for collecting: watch parts, in the form of a myo-potential noiBopOHHoro table with a location: around it by working mechanisms. Pa. similar machines assemble nodes, consisting of parts from which the farm and the sizes can be terminated, or can be oriented in the drawer, and we can read T (ra1Nsportir0) (it is not always possible to accumulate and accumulate (in the original position) in the trays). for parts included in the clock balance assembly

ШТ1И1ФТ01ИМЙМ ПРОДОМ.

The rim of the balance represents a flat disk and has no external geometric elements, allowing the holder to fix its angular position in the trays. Therefore, the angular orientation of the rim should be made directly in the transport nest of the rotary one. The task is complicated by the fact that in one of the spokes (jumpers between the sector windows of the overhang there is an offset 0 | relative to the center® hole of a small diameter for the pulse tmft. With a single-axis supply of balance axes to the trays of the first section, it is impossible to cut

It is impossible for them to accumulate in a closed channel, whose cross-sectional elements are rigidly connected to each other.

The purpose of the invention is to increase productivity by improving the quality of the assembly. This goal is achieved by embedding mechanisms in the automat for angular 0 | orientation of the disk base parts. and axes with transverse groove 10M directly at work positions.

To eliminate the effect of table indexing errors on the accuracy of the coordinates of small holes machined in the base parts, the latter are fixed in the table nests only in part of their outer and

In the inner contours, leaving the rest of the available for basing on fixed bases located around the table and in-support vertical power loads.

The aito load of the assembled parts is taken from the two-vibra-vibro-buoyers 6 (for the rims and axles) and one-bowl 7 of the poles (for I1M pulleys | f: GOV). Both bowls of the vibrating hopper 6 are equipped with a single-piece mechanism (| Cutter MI), from where the parts arrive at positions I and IV through trays 8 and 9.

For the piece output and rotation to the vertical position of the impulse unit, there is a special rotary mechanism 10, installed next to the ViPenBuNeX1Pi7.

The turntable jacks are figured depressions 11, in which the rims of the balances are placed with a certain amount of clearance, often with a single inner contour a and fixed in one of the sector windows. The rest of the rim is supported on a fixed stand 13 located around the turntable and replaying all the vertical forces of processing and assembly.

Above position I (see phi1, 2, 3) there is a fixed strap 14 with a through window / 5 for preliminary (coordinated) fixing of the rim, balance, and a rotary head 16 with four support legs and 1N1Nm | And finger mn (pins). The shafts 17, which are open around the periphery of the rim, are pressed, and the pin 18, located closer to the center, is oriented.

At positions P and III are; tool heads driven into rotation from individual electric motors, which are axially fed by an vertical slider of the automaton. The two positions are based on fixed positions, and the fixed supports extend: mi lovi | mi-.

In section IV, the mechanism of the angular orientation of the axis of the balagas is installed. It is simultaneously pressed into the disk basic part (see Φ | Ig. 4, 5). A part of the mechanism consists of a cz of the guide wall 19 and a podtjky 13. On the guide wall there are fig-ural deepening 20 and stop 21. The movable part, mounted with the help of the bracket 22 on the vertical slider 23, includes a fitting 24 and a horizontal rod 25 with rygazhagnm P; p | Izhim 2-6. In this way, the latter can be mixed in two directions, horizontally and vertically, carried out at

This is the fragile orientation (according to the position of the transverse groove of the axis) and the pressing of the axis 5 into the rim 2. To this end, a figure ledge 27 is provided on the lower part of the clamp.

At position V (| see Fig. 6, 7), an M feed supply mechanism I is installed, pressing in pulleys, consisting of a mechanical rifle 28 with two elastic holders 29 for feeding 1 and pressing 1 pins, a swivel head 10 fitted with nest 30 with constant ngmg, magNI | Tom 31, and vibrobunker 7 for the same pins. The vibrating hopper drive, covered with a flat round lid 32, is dropped with some clearance onto the oblong bar 33, rigidly fixed on the vibrating hopper bowl. Such a structure ensures that the lid is turned off when the bowl is vibrated, which contributes to the directional movement of the pins along the tray of the accumulator.

At the position VI and | there are special electrical contacts that check the presence of Im | pulsed pins and axles pressed into the rim. Following the position, the VI position is a reducible electromotive Hub 34 (see Fig. 1) to sort the assemblies assembled on an automatic machine 1 into two groups - complete and incomplete.

The machine works as follows. About | balance of balance, issued by a slam-shut from vibrator, 6, but the track 8 enters window 15 above position I. Rotator; the head is lowered to a level at which the bottom ends of all the pins are spaced from the upper plane of the turntable by 0.2 to O3 mm. Then, the head rotates 360 °, during which pin 18 rotates the rim by one of the spokes. At the time of assembly of one of the sector windows of the rim with the corresponding (M lug of the turntable jack: with the aid of the Stiletto 17, the rim is placed in this slot. Being in the turntable, the rim is successively placed on the other working positions of the automat. "

At positions II and III are centered and drilled in one of the rim spokes a hole for the impulse pin. Before the treatment, the rim is fixed with a special rim and catchers along the central hole in the spoke. Jet uda, eTS with a jet of compressed air.

On the IV POSITION (see phi1G. 3), the rim rests on a fixed support 13. The axis of the 5 bala; , provided by the cut-off device of the vibrating hopper 6, flows through the spring tray 9 into the choke 24 and stops, and stops 21 on the wall 19. At this moment, the movable part together with the lever clamp 26 is in the bottom of the LENGTH. frees the axis, which is kept from falling from the stop 21 of the 11 st1st skewed part of the figured overhang. Next, the horizontal retraction (along arrow 0) and the approach (along arrow II) of the pressure are successively performed.

After that, the axis L | 0 is sent; the lateral ledge 35 is pressed to the circular circular wall 36 of the gigantic recess, which is a continuation of the semicircular groove serving as the right direction for the inpw axis, which is pressed in, occurs when the whole moving part is lowered. At the same time, the axis is pushed against the groove of the figures. By the projection of the p-pinch.

From the vibrating hopper, the pins are single-piece nonad. I1t into the socket 30 of the head 10, which rotates them into a vertical position. On the way, the pins are taken away by the elongated holders 29 of the mechanical arm, transferred to the turntable and pressed into the rim of the ball: NSA resting on the movable stand 13.
