Description

The invention relates to a machine tool industry, in particular to the design of an auto operator, and can be used to assemble body parts.

The purpose of the invention is to expand the functionality of an auto operator by increasing the number of degrees of mobility of moving its gripping mechanism and increasing reliability of operation by increasing the accuracy of orientation of this mechanism.

FIG. 1 shows the proposed auto-operator built into an automatic assembly line, a general view; in fig. 2 is a view A (rotated) in FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 - node I

In the automatic line, the cylinder block 2 is mounted in the satellite 26 of the conveyor conveyor 27, and is fixed in the machining position to the tool 28. The heads 1 are placed on the conveyors 29.

The auto operator works as follows.

The satellite 26 with the cylinder block 2 is supplied by the conveyor 27 to the working position 10 of the automatic line, where the satellite 26 is fixed in the fixture 28. The heads 1 by the conveyors 29 are fed to the processing position. The carriage 4 of the auto operator at this moment moves to the zone of the last head 1 located on the conveyor 29.

in fig. 2; in fig. 5 — node II in FIG. 2. 15 The locking mechanism is lowered; from hydraulic auto operator is used in automatic 13 through screw transmission 14 rolling pins

11, the body 15 is moved with the collets 16 placed on it. The latter are gripping lines for assembling the head 1 with the cylinder block 2. Heads 1 are mounted on two inclined surfaces of block 2 with fixing heads 1 for fastening studs 18

3. The lines are used and clamped by a hydraulic cylinder. Mechanism

grip rises, lift head 1.

Then the housing 8 rotates at an angle of 45 ° and rotates the gripping mechanism 1 located therein. Simultaneously

two similar auto-operators, installed symmetrically with respect to block 2. Each of the auto-operators contains a movable carriage 4 mounted on the portal, consisting of guides 5 supporting

pillars 6. The carriage 4 has a drive 7, a re- 25 carriage 4, together with a displacement housing 8 along the guides 5, made along the guides 5 to the collecting position - in the form of a rack. transfer. On the carriage 4 there is a housing 8 with a rotation drive thereof, made in the form of a hydraulic motor 9 and a gear 10, the output link of the cot and the head 1 is lowered. When this happens, both the levers 21 and 22 of the orientation mechanism placed on the housing 15 are lowered. The power cylinder 25 is turned on, and the levers

the new studs 3 of the block 2 of the cylinders and orient the locking mechanism with the head 1 relative to the block 2. Then the head 1 is preset onto the block 2, for which the mechanism

The swivel is rigidly connected to the housing 8. On the latexes of 21 and 22, with the prisms 23, the gripping mechanism is mounted to the last, the rolling pins 11 of which are connected by means of a hinge 12 (Fig. 4) with a drive made in the form of a hydraulic motor 13 and screw self-brake transmission 14. Rolling pins

11 are rigidly connected to the body 15 of the grip 35 and the orientation moves forward the grip low, on which two spring-loaded collets 16 are driven and three are loaded with prisms 23, which are thrown over the 3 levers 21, and the swivel 12 allows the rolling pins 11 together with the locking mechanism and the 1 d0 head, self-aligning with respect to the second assembled part, the cylinder block. Then, the gripping and orientation mechanism stops, the collet 16 opens and the levers 21 and 22 retract, after which the pusher 19 moved by the actuator 20, with the synchronization rod 24, while 45 returns the head 1 to the block 2. one of the levers 21 is pivotally connected c Then, the gripping and orientation mechanism, the thick cylinder 25, also the hinge 19, and then the carriage 4 with the housing 15 mounted on the housing 15. the som 8 is returned to its original position.

17. The collets 16 are installed in the housing 15 with the ability to interact with the studs 18 on the head 1. In the housing 8, the tappets 19 are also installed with the drive 20 displacing them. On the housing 15 of the gripping mechanism, an orientation mechanism is installed, made in the form of two levers 21 and 22 with prisms 23 connected between

In the automatic line, the cylinder block 2 is mounted in the satellite 26 of the conveyor conveyor 27, and is fixed in the machining position to the tool 28. The heads 1 are placed on the conveyors 29.

The auto operator works as follows.

The satellite 26 with the cylinder block 2 is supplied by the conveyor 27 to the working position of the automatic line, where the satellite 26 is fixed in the fixture 28. The heads 1 by the conveyors 29 are fed to the processing position. The carriage 4 of the auto operator at this moment moves to the zone of the last head 1 located on the conveyor 29.

The locking mechanism is lowered; from hydraulic motor 13 via screw gear 14 rolling pins
