SU776886A1 - Apparatus for vibration-type working of inner surfaces of tubular parts - Google Patents

Description

The fopyio is inserted into the plug 10, which is possible to swing on the axis 11. The second end of the plug 10 is connected to the stem 12 of the double-acting internal chamber 13. The stem of the internal chamber is fixed on the membrane 14.

A support sleeve 15 is also located on the rack 2 in the guide sleeve 8. The axial movement of the sleeve 15 is limited by retaining rings 16. The movable 9 and the support sleeve 15 are connected by means of rubber-cord elements 17 with sleeves 18 installed with the help of swing bearings 19 on the uprights 20 and 21. The sleeves 18 mounted on the uprights 20 and 21 are of the same design, only the left sleeve 18 is connected by means of a V-belt drive 22 with a rotational drive of the workpiece 23, which are mounted between the movable 9 and the fixed 15 sleeves. The rotational drive of the machined parts 23 consists of an electric motor 24, an elastic coupling 25 and a gearbox 26. The rotational drive of the parts has the ability to move in the vertical direction when the angle of inclination of the frame 1 changes due to the pneumatic cylinder 27. In sleeves 18 there is a roller bearing 28, which carries clamping one end of the rubber-cord elements 29 to the sleeves 18.

The other ends of the rubber-cord elements 29 are fixed to the right 30 and left 31 valves of the containers 32 and 33 with the medium 34. The right valve 30 has a window 35 in the lower part connected in turn with the windows 36 and 37 of the right container 33. The left valve 31 has a window 38, in the upper part connecting with the windows 39, 40 of the left tank 32. The left tank 32 moves in the vertical direction due to the pneumatic cylinder 41, the right tank 33 due to the pneumatic cylinder 42.

The described device operates as follows.

When air is supplied to the left cavity of the pneumatic chamber 13, the membrane 14 with the stem 12 moves to the extreme right position. Fork 10, turning on axis 11, moves sleeve 9 to the leftmost position. The workpieces 23 are installed between the sleeves 9 and 15. When air is supplied to the right cavity of the pneumatic chamber 13, the sleeve 9 is moved to the right position, the ends of the workpieces come into contact with the tapered surfaces of the sleeves 9 and 15, followed by pressing to the sleeve 15. Thus way is the installation and fixing of the processed products in the fixture. Next, the frame 1 is installed at an angle of inclination to facilitate the best movement.

Environments from one tank to another. The angle of inclination of the frame 1 is adjusted by changing the stiffness of the pneumatic bellows 4. The pneumatic cylinder 27 tensions the wedge-belt transfer 22 of the rotational drive of the workpiece 23. The window 35 of the valve 30 is connected to the window 37 of the container 33. The window 38 of the valve 31 is connected to the window 39 of the container

32. By switching on the electric motors .7, the elastic vibrators 6 receive rotation of the vibrators 5, and by turning on the electric motor 24, by means of the elastic coupling 25, the gearbox 26, the belt-drive gear 22, the products 23 receive a slow rotation. Under the action of vibration, the processing medium 34 begins to flow through the windows 35, 37, the rubber-cord element 29 of the sleeve 18, the rubber-cord element 17

sleeve 15 into the internal cavity of the product 23, then through the sleeve 9, the rubber-cord element 17, the left sleeve 18, the left rubber-cord element 29 into the left cavity 32, through the windows 38, 39. At the end of processing

the piston of the pneumatic cylinder 42 is lowered down, the window 35 is connected to the window 36 of the tank 33. The piston of the pneumatic cylinder 41 rises up, the window 40 of the container 32 is connected to the window 38 of the valve 31. By changing the pressure in the elastic suspension of the frame 1, the angle of inclination of the tool changes. Thus, the right cavity 33 is transformed into a loading one. The pneumatic chamber 13 is made to unlock the processed products 23 and install the following. The pneumatic cylinder 27 produces the tension of the V-belt transmission 22. The device is prepared for the next processing cycle.
