SU1202840A1 - Automatic operator of automatic assembling machine - Google Patents

Description

one

The invention relates to mechanical engineering and instrument making and can be applied in automatic assembly devices.

The purpose of the invention is to expand the functionality of an auto operator due to the presence of an additional movement of the auto operator gripping device at an angle, for example 90, to the direction of its main movement.

FIG. 1 shows the operator, the initial position; in fig. 2 - the same at the time of capture of the product.

The auto-operator contains a power cylinder 1 with a piston 2 and a housing 3, the immersion has moved in the directions 4, In the housing 3, gear 5 and gear rails are mounted

6 and 7, forming a gear-rack and pinion with the gear; Axles of rail 6 and

7 intersect at an angle of 90. The rail 6 is mounted with the possibility of longitudinal movement in the supports

8cases 1n are rigidly connected to the rod 9 of the power cylinder 1. On the threaded part 10 of the rail 6 a nut 11 is installed and a spring 12 is mounted, which rests at one end on the hd 11 and the second on the casing 3

The movement of the housing 3 in the direction of A nimim A is limited to the supporting surface 13 and the limit switch

The second rail 7 is mounted with the possibility of longitudinal movement in the supports 15 of the housing 3. The flange 16 and the gripper 17, for example, magnetic, are rigidly fixed to the lower part of the rail 7.

The auto operator works as follows.

When air is supplied to the right cavity of the power cylinder 1, the rod 9 moves to the left and through the nut 11

and the spring 12 moves along the guides 4 body 3 up to the stop against the supporting surface 13. At the same time, the relative movement of the body 3 relative to the rod 6 does not occur, because the stiffness of the spring 12 is greater than the friction force of the body 3 in the guides 4, e -redulent transfer - 5-6-7 does not work.

 After the housing 3 stops as a result of its abutment into the bearing surface 13, the rail 6 is rigidly connected to the rod 9 of the power cylinder.

5 pa 1, continues to move, compressing the nut 11 with the spring 12 and rotating the gear 5. Simultaneously, the rail 7 begins to move downward until the grip 17 touches the assembled

20 product. The stroke of the rail 7 with the gripper 17 is limited by the amount of compression of the spring 12. The reverse stroke of the power cylinder 1 is activated after the gripper 17 has triggered.

25 rail 6 begins to move to the right. In the first stage of this movement, the body 3 remains stationary, since the stiffness of the spring 12 is greater than the frictional forces in the rack and pinion gear 30 5-6-7.

Moving to the right, the rail 6 rotates the gear 5, which, in turn, reports the upward movement of the rail 7 with the grip 17 and the assembled

3J product. The movement of the rail 7 upwards continues until the flange 16 stops against the housing 3. Thereafter, the rack-and-pinion gear 5-6-7 closes and further movement of the rail 6 to the right.

jQ is already carried out together with the housing 3. The movement is carried out before the assembly of the assembled product into the container or the tray and the operation of the limit switch 14.
