Description

Automata for field-huw-l grooves of ball bearing rings fed from a hopper, poliwal "cams", knobs on the ends of the levers, and abrasive belts, unwound from, the coils, to the surface to be treated are known.

The key feature of the proposed automaton of the same type is to fasten the ring in the process of pali; to insert a split pin into the barrel, equipped with protrusions and entering the grooves right into the elbow, elos sh-pindel, the cavity of the slot for the slot, the slot for the slot, the slot, the slot, the slot, pinto, the cavity of the slot. processing of the ring from the hopper and passing it under the influence of the pusher to P1ruz; TiaiKoe execution of the automatic machine obahepaca a short way of the Kozel from the bunker to the maat of his processing.

On . 1 schematically depicts the proposed machine in an axial section; on fit. 2- polishing pads in work; in fig. 3-two projection1I1I times (a spring ring was produced.

Several rings, polished, are put into the bin I. The tube 2 moves

pusher 3 on the left side of which is on a shaft; p1 pod; kpnik 4; a pusher 5 is pushed; pusher 5 at; water pivots with lever 6, swinging on axis 7 under the influence of cam 5, radial shaft 9; a constant contact between the roll; -5К ol1 10 and cam 8 provides the load 11. With noiBopoTe lever 6, counterclockwise clockwise cap 5 of the pushbutton 3 leans into the butt of the ring in pipe 2 and the ring doesn’t bother Section 12, which is driven by the pulley 13. In the spindle 12, several rings are placed, 1 of which the leftmost ring is clamped by a split spring ring 14, shown separately in FIG. 3. The ring 14 is provided with a vacuum; MI, which are included in the end grooves of the rotating spindle 12. The clamping force is sufficient to ensure reliable fastening: the polished ring in the Sch | Pindel under the most intensive processing modes.

The use of such a construction. The mechanism of clamping rings in the spindle greatly simplifies the machine, because

a simple .and short path of the rings from loading to ejecting from the spindle after machining.

The processing of the ring groove is carried out by abrasive or by polishing tape 15, which is applied to the surface of the polished ring groove by polishing pads 16 placed at the ends of the levers / 7. The working force is created by the membrane 18 with the air supply through ash ash 19, which is activated by the cam 20. In the off position, the lyrical valve И1КИ 16 is spring 21. Oc: And 22 levers / 7 are locked on the frame 23, the amtor is pumped around an axis passing through the axis of symmetry of the polished ring. Swinging movement of the frame 23 informs the pusher 24 from the cam 25 through the lever 26, whose axis is fixed to the lever 27. The axis of rotation of the frame 23 is created by screws that are screwed into the plug 28, fixed to the lever 27. This lever swings the wok, axis 29 and is driven from cam 30. By turning the lever 27, the field is entered. p0. valny1ko.v 16 into the molded ring and their removal from the ring at the end of p. olir | 0. The stop 31 serves to limit the rotation of the lever 27.

Two rolls of tape 15 are placed between the discs and 32, which are loosely mounted on axles 33. The ends of the tapes span the floor, the curtains 16 and the PROPOD between two rollers 34 and 35 that have a tooth on the cylindrical surface. The roller 34 serves as the ratchet wheel at the same time. In the quivering of the lever 27, with all the rules of the river, the details of the arm counter clockwise. The wheels of the 34 K meet the dog 36 in their path and turn to the angle of the shaft. As a result of the rotation of the roller 34, it is moved a certain distance and the polishing unit 15 is sandwiched between the rollers 34 and 35. Thus, the distance (instead of the waste section of the tape 1 to the polisher 16 is fresh.

At start-up, the spindle 12 and the camshaft 9 begin to rotate; cams 8 and 30 communicate dBIZhie levers 6 and 27; after the determined number of strokes of the pusher 3, the hole in the spindle is clogged with rings and the leftmost ring 0: the ring is firmly clamped in the split ring 14; the lever 27 is paulochka along the arrow and the polirsdals 16 are inserted into the rotating ring in a shear.dH | BUT: m spring 21 state. Zatem through zolotnik 19 and monobran 18 is supplied under pressure .EC; Zduh and 1POLI | p-o-valnIlIkI 16 are moved apart, ex: izh1I1ma polish al len.tu 15 to io1top: ovity of the jar of the ring; paiMiKa 23 swings the axis of its axis of rotation with the action of the pusher 24, with the result that a gritty grid is formed on the noiBCpxiHooTM of the gutter; after a certain time, the spool disconnects the membrane from the network and the spring 21 reduces the floor (Ki 16 opening, after which the lever 27 is turned counter-clockwise and leads out of the ring. The pusher 3 moves the entire column. in the center to the left of the ring One of the rings and the whole of l; I1KL of the work of the automatic mat. BiHoiBb is repeated.

Subject invention

AVTOMAT for polishing the grooves of the outer rings of ball bearings, fed from the hopper, placed at the ends of the KOI koi pivot and leaking to the polyravels, and the use of abrasive tapes to the processing surface, unlike that, the purpose of the KP is to the processing surface, which is the aim of the KP to ensure the processing of from the bunker to the place of its processing, in order to fasten the ring during its polishing H1I, a split spring ring was used, which was inserted into the end slots included in the end grooves. return: an open spike, the cavity of which serves to receive the ring from the bunker and the gap KAP under .BOsaeucTiBHeM tadkatel in. spring ring.
