SU1400879A1 - Multiposition gripper of industrial robot - Google Patents

Abstract

The invention relates to the field of mechanical engineering, namely to gripping devices of industrial robots, A, and improves the reliability of gripping a part. In the housing 1 is placed the actuator in the form of a power cylinder 2, the rod 3 of which is equipped with a multifaceted helical gear. The rake stem 3 is in engagement with the helical rails 4. On the rails 4 fixed movable jaws 5. On the spring-loaded carriage 7 there are stationary jaws.6. When you turn on the SI.POVO cylinder 2, the rod 3 moves the moving jaws 5 through the helical gears 4. The moving jaws 5 through the parts 9 through the carriage 7 ensure the self-installation of the fixed jaws 6, 6 or less. S (l

Description

Fi9.1

The invention relates to mechanical engineering, in particular to gripping devices of industrial robots.

The purpose of the invention is to increase the reliability of capturing the part.

1 shows a multi-position gripper for two parts, a general view; FIG. 2 is a view A of FIG. 1; FIG. 3 shows a multi-position gripper for three parts, a general view; in fig. 4 - view B on fig.Z; figure 5 - multi-position capture when grabbing hollow parts, a general view; Figure 6 - the same, with the internal and external arrangement of the fixed jaws, a general view.

The multi-position grip includes a housing 1, an actuator in the form of a power cylinder 2, the rod 3 of which is equipped with a multi-faceted helical gear that engages with the helical gears 4 movably mounted in the housing 1, movable jaws 5 fixed on the helical gears 4, fixed jaws 6 mounted on the carriage 7 installed in the guiding groove of the housing 1 for movement in the directions of movement of the movable jaws 5, centering springs 8 placed between the housing 1 and the carriage 7. Sponges 5 and 6 capture the parts 9 .;

Multiposition capture works as follows.

When the power cylinder 2 is turned on, its rod 3 pushes helical gears 4 with movable jaws 5 fixed on them, which, through the gripped parts 9, act on the fixed jaws 6 and carriage 7. The latter self-aligns in the guide slot of the housing 1, occupies the position defined by dimensions and the shape of the details 9.

When the ram cylinder is disconnected, the carriage 7 with fixed jaws. 6 returns to its original position by centering springs 8, and the movable jaws 5 return to the initial position with rod 3 of the ram cylinder-2.

Claims (1)

Invention Formula The multi-position grip of an industrial robot, comprising a casing, fixed jaws and motorized jaws connected with a drive, is required to ensure that the grip is equipped with a floating spring-loaded carriage, on which the fixed jaws are placed with the possibility of reinstallation, while the floating - spring-loaded carriage is installed in the housing with the possibility of moving in the directions of movement of the movable jaws.
