' Ausführungsbei game

In the following, the individual operations at the eight tact stations according to Pig. 4 described.

In cycle 1, the insertion of the hose with the valve body takes place in the clamping device (Fig. 1). 'The valve body is held by the two clamping bolts (2), wherein the angle lever (3) and the compression spring (4) transmit the necessary clamping force. The opening of the clamping device is effected by a hydraulic system.

The clamping to the required accuracy is achieved by a respective dowel pin in the clamping bolt (2) and a milled hat in the body (1) or realized by the screws (5).

The retaining clip (7) screwed to the tensioning device secures the clamped tube from falling and ITachuntendrücken during the screwing operations in each station. 5

The required 8 fixtures according to Pig. are firmly screwed to the turntable (20).

The washer is conveyed by a vibratory conveyor (22) in a magazine and provided there in position.

By a transport arm with vacuum suction head (23) which is attached to the top plate (24), the valve washer is sucked and pivoted over the valve body,

By a compressed air pulse from the suction head, the valve washer is blown onto the valve body.

Bar 4

In cycle 4, the hex nut is screwed about 10 threads on the valve body.

For this purpose, the hexagon nuts are conveyed by a vibrating conveyor (22) into a magazine. By a transport arm with gripping pliers (8), the hexagon nut is removed and placed on a slotted in the direction of tray (16) symmetrically to the valve body.

The screwing is triggered, in which the hydraulic - likzylinder (10) is pressurized. The screwdriver (6) slides down the guideway (9), grabs the hexagon nut with the screwdriver bit (12) and screws it with the valve body about 10 threads (Pig. 2).

The screwdriver (6) slides back to the starting position. During transport to the next cycle station, the valve body leaves the slotted shelf (16) through the slot and the shelf is pushed back by the spring (17) in ö.ie starting position.

In cycle 5, the hexagon nut is tightened by a screwdriver with an adjustable torque.

The screwing is triggered, in which the hydraulic cylinder (10) is pressurized. The screwdriver (6) slides down the guide track (9), 30

At the same time, the clamping device according to FIG. 1 is opened hydraulically. By the centering pin (15) which is fixed to the pneumatic cylinder (13), the valve body is fixed in position.

The hexagon nut is detected by the screwdriver bit (18), which by the screwdriver (6) via an angle drive (14) according to Pig. 3 is driven. At the same time the Yentilgrundkörper with the hose is positively secured by 2 in the screw (18) introduced backup surfaces, to prevent turning during the screwing. After the completion of the screwing operation, the screwing unit according to FIG. 3 returns to the starting position and the clamping device according to FIG. 1 is closed and secures the valve main body in its position.

In cycle 6, the rim nut about 15 threads is screwed onto the valve body.

The rim nut is conveyed by a vibratory conveyor (22) in a magazine.

By a transport arm with gripping pliers (8), the rim nut is removed and placed on a slotted in the direction of tray (16) symmetrically to the valve body.

The screwing process takes place in analogue to clock 4.
