Description

11310203

The invention relates to automation of technological processes and can be used, for example, Stage 5 to x

measures, as a gripping device for industrial robots used in mechanical engineering, instrument making and other devices of technology.

The purpose of the invention is to increase the versatility of the device by ensuring that a single device captures a part independently through axial channels with and without a hole.

Fig. 1 shows a jet capture device, the initial state in Fig. 2 is section A-A in Fig. 1; Fig. 3 shows a jet capture device in the process of transferring a set of parts with central openings; Fig. 4 shows an inkjet gripping device with through slots in the side working portions of the mandrels for transferring sets of parts without central holes.

Inkjet gripper with

holds the housing 1 and the rod, with conically centered autonomously movable sleeves 2, each of which has deaf axial channels 3 and inclined radial nozzles 4 and 5, open respectively in and out of the rod relative to deaf axial channels 3 to the sides of the contact surfaces of the sleeves 2

Each of the sleeves 2 ram assembly has an individual axial displacement drive and a compressed air distributor (not shown). The side working part of each sleeve is full with through slots 6 or with through holes.

Inkjet gripping device operates as follows.

Being one of the actuators of an industrial robot or manipulator, the jet gripper operates from a common control system of a robotic technological complex and is automatically reconfigured from the initial state to the working one, corresponding to the size and number of parts to be transferred and installed.

Each of the telescopic sleeves 2 of the key rod is set to the required relative position by an individual axial displacement drive (not shown). The gripping of parts with a central bore is accomplished, for example, by inserting

pre-adjusted to a predetermined shape of a set of sleeves 2 into the holes of parts previously oriented in a single-position loading device or sequentially oriented in several positions of the loading device.

Supply of compressed air to each of the telescopic mandrels

ly 3 from the corresponding distributor (not shown). This creates a holding head of compressed air jets, which, through inclined radial nozzles 5, presses against the lower surfaces of the parts and presses them against the respective end surfaces of the sleeves 2. This position of the composing rod is maintained during

Capturing parts and moving them to the installation area (assembly).

The gripping of parts without a central bore is carried out in a similar manner. However, a holding head of compressed air jets acting on the bottom of the part is created in this case through inclined radial nozzles 4, which open inside the rod relative to the hollow axial channels 3 of the sleeve 2, which surrounds the part outside. At the same time, the presence on the side working parts of each of the sleeves 2 additional through slots 6 or holes allows to hold sets of parts without central holes, because through the slots 6 or holes the compressed air supplied to the part leaves into the atmosphere from the resulting closed space between the inner surface of the grip and the top surface of the portable kit held below the part.
