Description

F

The invention relates to devices for moving workpieces between positions of a processing machine, preferably a press.

The purpose of the invention is the expansion of technological capabilities by ensuring the turning of the workpiece by 180 at any position of the processing machine.

FIG. 1 shows the transfer mechanism, a view to the glider in FIG. 2 kinematic diagram of a hand with a rotation drive; in fig. 3 is a view A of FIG. Hshhem turning gripper with additional rotation); in fig. And the same, without additional rotation, turning; in fig. 5 is a diagram of the transfer of blanks into streams of a punch with various steps between the streams and with the additional rotation of the gripper in FIG. 6 - the same, with the same steps between the creeks without additional rotation and with additional rotation; in fig. 7 is a view B in FIG. one.

The transfer mechanism consists of a bed 1, a drive for rotating hands, consisting of a cylinder 2, mounted under the bed 1, a rail

3 mounted on a pneumatic cylinder 2 of three arms mounted on a bed 1, each of which (FIG. 2) includes a gripping member

4, mounted on the shaft 5, which is mounted in the housing 6. On the shaft 5, the pneumatic cylinder 7 of the gripping member is mounted. The housing 6 is attached to 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. The sleeve 9 is installed in the housing 11, with which the arm is attached to the frame 1. Inside the sleeve there is a shaft 12, on which rotary sealing connection 13 is installed. Shaft 12 is connected kinematically with shaft 5 by cables 14

and is kept from being rotated by a fork 15 fixed to the housing 11 with screws 16. On the sleeve 9 on the conical neck, a gear wheel 17 is engaged which engages with the rail 3. In the housing 6 a fixing screw 18 is installed. 7. A compression spring 21 is installed on the rod 19. The rotational drive of the hands is closed by a casing 22. The transfer mechanism is part of the front-mounted manipulator and is mounted on the lifting and lifting mechanism (not shown).

5 Rotation by rotation can be carried out in two ways: with an additional rotation of the gripper and without additional rotation of the gripper. The mechanism of transfer works with

0 additional rotation of the tong (Fig. 2 and 3) as follows.

The pneumatic cylinder 2 with the rail 3 fixed to it moves in the direction of the left arrow in FIG. 2. In this case, the

S into gearing the gear wheel 17 of each hand with the rail transmits the torque through the tightened conical connection to the sleeve 9, turning it. Along with him turn

0 rule 8 and the casing 6 fixed on them. At the same time, the shaft 12 is kept from rotation by the fork 15. The locking screw 18 is turned out of the shaft 5, which can now be turned

5 in the housing 6. When the sleeve 9 rotates around the shaft 12, one branch of the cable 14 runs onto the fixed shaft 12, and the other escapes from it, thereby turning the shaft 5 with

0 it grip 4 at an angle d. equal in magnitude to the angle of rotation of the sleeve 9, but with the opposite direction of rotation. . Thus, the detail in the gripper during its transfer from the stream to the stream

5 always takes the same position in relation to the plane

plugs of the stamp.

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

A screw 18 is inserted into the body of the vacuum: 5 and prevents it from rotating relative to the housing 6, and the plug 16 is disengaged from the shaft 12, allowing it to rotate. When turning the sleeve 9, the shaft 5 is stationary relative to the housing 6 and the cable 14 rotates the shaft 12 inside the sleeve 9 in the same direction. The detail in the process of transferring from a stream to a stream is turned over.

Air into the pneumatic cylinder 7 of the gripper enters through a rotating sealing connection 13, shaft 12, sleeve 9, rotating telescopic connection 10 under the piston 20, which through the rod 19 compresses the jaws of the tongs 4. When compressed air under the piston 20 is not present, the spring 21 expands the three jaws of the tongs . The turning radius of the rail is equal to half the step between the creeks and movements are set in the guides 8 in the sleeve 9. At the same time, the branches of the cable overlap and fasten again. The installation of the gripper along the brook is carried out by moving the body 11 along the bed frame 1. The gear wheel 17 should not be tightened over the cone of the hollow shaft 9. 4 The transfer mechanism allows placing the arms along the flux m, the steps between which are not equal to one another. (Fig. 5), as well as adjust part of the hands on the rearrangement with additional rotation, and the other part on the rearrangement without additional rotation (Figure 6). All this expands the technological possibilities of the proposed transfer mechanism.
