Abstract

The device relates to the field of engineering, in particular to the automation and robotization of stamping production. The purpose of the invention is to improve serviceability and reduce changeover time. For this, in the device for transferring the blanks, the pulley of the rotary shaft 12 is made of two parts 14 and 16 having conical surfaces 17, one of which is rigidly fixed on the rotary shaft 12, and the other is mounted on the rotary shaft rotatably and is connected to the first along the conical surfaces 17. Moreover, the ends of the flexible kinematic connection 19 are passed through the pulley holes of the power cylinder, passing through its cylindrical surface, and are fixed on each part of the pulley of the rotary shaft, and the stopper has a terminal fastened It connects it with a rotary shaft 12. 7 Il. gg with (L IS 1U. with O5 05 K O5 cl N)

Description

I The invention relates to mechanical engineering and can be used in industrial robots, manipulators, auto operators and punching automation devices.

The aim of the invention is to improve serviceability and reduce changeover time.

FIG. 1 shows a schematic representation of the device, a general VIEW; FIG. 2 is a kinematic diagram of a hand with a rotational drive j in FIG. 3 is a view A of FIG. 1 (scheme of rotation of the gripper with an additional rotation); in fig. 4 is a view A in FIG. 1 (the scheme of rotation of the gripper, without additional rotation — canting) —in FIG. 5 is a view B in FIG. one; in fig. 6 shows a section B-B in FIG. one; FIG. 7 is a sectional view of FIG. one,

The transfer device consists of a bed 1, a rotational drive arm consisting of a pneumatic cylinder 2 installed under the bed 1, a rail 3 mounted on the pneumatic cylinder 2, three hands mounted on the bed 1 each of which (FIG. 2) includes a gripping an organ 4 mounted on the shaft 5 which is mounted in the housing 6; A pneumatic cylinder 7 of the gripping member is mounted on the shaft 5 The housing 6 is mounted on the guides 8 which are mounted on the sleeve 9, the pneumatic cylinder 7 is connected through a rotating telescopic sealing connection 10 to the sleeve 9, mounted in the housing 11, with which the arm is attached to the bed 1; Inside the sleeve there is a rotary shaft 12 on which a rotating sealing joint 13 is mounted. On the shaft of the rotary shaft 12 (FIG. 5) a part of the pulley 14 is fixed to the shaft 15 ,, On the same shaft, a part of the pulley 16 is mounted, which is connected to a part of the pulley 14, rigidly connected to the shaft by a pin 15; Jivani nuts 18, the ends of the cable 19 are fixed screws on the parts of the pulley 14 and 16, the cable 19 passes through the holes 20, executed in the pulley 21 of the power cylinder mounted on the shaft 5. The shaft 12 is held from turning by the terminal

clip stopper 22 mounted on the housing 11 (Fig. 6 and 7).

A gear wheel 23 is mounted on the sleeve 9 on a conical neck; the gear wheel 23 engages with the rail 3; A fixing screw 24 is installed in the housing 6; The rotational drive of the hands is covered by a casing 28. The transfer device is included in the frontal arm and is mounted on

Extend and Lift Mechanism (not shown) “Rotation by turning can be carried out in two ways; with additional gripper rotation and without additional gripper rotation,

 The device with the additional rotation of the tong works (Fig, 2-4) as follows,

The pneumatic cylinder 2 with the rail 3 fixed on it moves along

the left arrow (fig. 2), wherein

The gear wheel 23 of each arm with the rack, which is engaged, transfers the torque through the tightened conical connection to the sleeve 9, turning it. Along with it, guides 8 and case 6 fixed to them rotate while the shaft 12 is kept from rotation by a stopper 22 with a fixed terminal connection.

The locking screw 24 is turned out of the shaft 5, which can now be rotated in the housing 6.

When turning the sleeve 9 around the shaft 12, one branch of the cable 19 runs over

onto the pulley of the stationary shaft 12, and the friend escapes into it, thereby turning the shaft 5 with the tongue 4 mounted on it by an angle equal in magnitude to the angle of rotation of the sleeve 9, but with the opposite direction of rotation. Thus, the part in the gripper in the process of its transfer from the stream to the stream always takes the same position with respect to the plane of the punch connector,

Without additional rotation of the gripper, the transfer mechanism works as follows (FIGS. 2 and 4).

The screw 24 is inserted into the shaft body 5.

and prevents it from rotating relative to the housing 6, and the terminal connection of the stopper 22 to the shaft 12 expands, allowing the shaft 12 to rotate. When turning the sleeve 9
