Abstract

The technological gripping head of the robot comprises a base plate (9), prisms (1, 15), a fixed jaw (2) and a swinging jaw (3), control cylinders (8), rods (4) and levers (7, 12). The prisms (1, 15) with support surfaces (13, 16) provided with bevels (14) are mounted on the base plate (9) and the jaws (2, 3) are mounted between pairs of support surfaces (13, 16) of the prisms (1, 15). The swing jaw (3) is preferably provided with a fork, which is mounted by the fork arms (19) in the fork holder (11) on the base plate (9) and on the fork arms (19) there are rods (4), between which is mounted a control lever (12) connected at one end to the rods (4) and at the other end to the connecting rod (6), passing through the prisms (1, 15) and the fork holder (11) and connected at each end by a lever (7) to the control cylinder (8).

Description

CS 276328 Ββ

The invention relates to a technological gripping head intended for handling crankshaft parts.

In the manufacture of a crankshaft that is formed of parts; parts are handled manually during production. Labor productivity is low and requires increased effort. Automatic handling of parts by means of an industrial robot is not possible using previously known gripping heads. These heads are not adapted to the shape of the crankshaft part, have large dimensions, do not ensure good self-locking in the event of a power failure and cannot guarantee a precisely defined position when moving to the next production operation.

The above-mentioned shortcomings are eliminated by the technological gripping head, which contains the base plate, prisms, fixed and movable jaws, rods and levers.

The essence of the invention lies in the fact that prisms with bearing surfaces provided with bevels are placed on the base plate and the jaws are placed between pairs of bearing surfaces of prisms. The pivoting jaw is preferably provided with a fork which is mounted by arms in a fork holder on the base plate and by rods mounted on the fork arms, between which a control lever is mounted, connected at one end to the rods and the other end to a connecting rod passing through the prisms and the fork holder. and connected at each end by a connecting lever to the control cylinder.

The technological gripping head enables automatic handling of crankshaft parts during its production by means of an industrial robot. It ensures precise gripping of the part in a defined position, automatic centering of the part, self-locking in case of power failure and good access to the part during finishing. Productivity will increase and workload will be reduced.

An example of a technological gripping head according to the invention is shown in the accompanying drawings, in which Fig. 1 is a side view, Fig. 2 is a front view and Fig. 3 is a plan view.

The technological gripping head consists of a base plate 9 on which prisms 6, 15 are placed against each other, the support surfaces 13, 16 of which are provided with a bevel 14. A fixed jaw 2 is placed on the base plate 9 between one pair of support surfaces 13, 16. a pivoting jaw £ is arranged between the second pair of bearing surfaces £ 3, 16. For pivoting mounting, the pivoting jaw 3 is provided with a fork, each arm 19 of which is provided with a first pin 5, by means of which the fork arms 9 are mounted in a fork holder 11 mounted on a base plate 6 and with a second pin 17 on which it is mounted. 4. between the handle bar 4 is mounted actuating lever £ 2 coupled at one end to the third stub 18 to the rods 4 and the other end is fastened to the connecting rod 6 extending pris ^mat y i, ^li £ fork holder first The connecting rod 6 is connected at each end to a lever 7, which is connected by a fourth pin 20 to a piston rod 22 of an actuating cylinder 6, fixed by a fifth pin 21 to the prism £ and £ 5. The control cylinders 6 are pneumatic and are interconnected by a pressure medium supply 10.

The gripping of the crankshaft part takes place in such a way that by the action of the pressure medium, the actuating cylinder 6, by extending the piston rod 22, the connecting rod 6 rotates over the lever 7. crankshaft arm link pin to fixed jaw £. In this case, the circular arms of the crankshaft part abut against the abutment surfaces £ 3, 16 of the prisms 1, 15 and the axial position of the part is defined by means of the bevels 14 of the abutment surfaces £ 3, 16 of the prisms £, £ 5. At the same time, holding the part in the event of a power failure is ensured by the self-locking mechanism formed by the pivoting jaw 3, rods 4, control lever 12, connecting rod 6 and pins 5, 17, 1θ ·
