The invention relates to mechanical engineering, in particular, to auto-operative devices designed to automate assembly processes in machine-tool construction, automotive, mechanical engineering, and the like.

A known auto-operator includes a housing, a gripper with a drive and gripping elements with a lip, and also a device for changing the jaws mounted on the gripper and made in the form of a screw mechanism, the screw of which has multi-directional thread G1.

The disadvantage of this auto operator is the low reliability of the gripping operation, due to the fact that in the process of moving the gripper due to jolts and vibrations, the spontaneous rotation of the screw of the jaw changeover mechanism is possible.

The purpose of the invention is to improve the reliability of the capture.

This goal is achieved by the fact that in an auto operator containing a housing, a gripper with a drive and gripping elements with jaws, as well as a device for changing jaws made in the form of a screw mechanism, the screw of which has multidirectional threads, the screw mechanism is placed on the housing of the screw mechanism nut are equipped with leads, and in the lips there are stubs made for these leads and clamps, which interact with the gripping elements, are located, and on the body there are additionally mounted fingers intended for and clamps.

FIG. 1 shows the proposed auto-operator, cross section; n FIG. 2 shows section A-A in FIG. 1) in FIG. 3 shows a section BB in FIG. one; in fig. 4 shows the section LB of FIG. 3j in FIG. 5 is a section of YYD in FIG. 3 (latching position before retooling) j in FIG. 6 - the same (the position of the latch during the changeover period)

The operator includes a housing 1, a device 2, a jaw spreader and a ring 3. On the grip 3 there is a 4 G bush installed with a spring-loaded latch 5 and a copier 6 hinged in it, as well as a movable frame 7 pushed by a spring to the collar on the grip 3.

On the frame 7 movably mount) 1rrvan pushers 8 with rollers 9, which. springs 10 are attached to copiers 6. Pushers 8 are rigidly connected with gripping elements 11, carrying movably mounted guides 12 jaws 13. in gripping elements 11 there are holes 14, and c guides 12 - grooves 15 under clamps 16.

The jaw changeover device 2 includes a screw 17 with multidirectional threads, mounted in supports 18 of housing 1, nuts 19 with drivers 29 and 21. In jaws 13, drivers 20 are made oTBepcTHJFi 22, and on case 1 fingers 23 are placed to act on clamps 16 and 24 nuts 19.

The operator operates in conjunction with the magazine 25, the cylinder 26 for dispensing the parts 27 and the mandrel 28, which is moved in the guides 29 of the hundred NINA 30. On the base 30 there are also a stop 31 and a copier 32, designed for interoperability. with a movable frame 7 and a latch 5.

The auto operator works as follows.

After the displacement of the mandrel 28 on the base 30 in the guides 29 to the center of the working position, a signal is given to the work. The cylinder 26 feeds its stock from the magazine 25 with the part 27 into the jaws 13. Then the cylinder rod 26 returns to its original position and the drive (not shown) of the gripper 3 is activated. The gripper 3 is; starts a downward movement, with the part 27 being in jaws 13,

puts the mandrel 28 on and down it, the frame 7 on the lowering part, rests against the stop 31, stops. and the grip 3 continues to move down, compressing the spring. Upon further movement, the gripper 3 with its copiers 6 acts on the rollers 9 of the pushers 8. The pushers rigidly connected with the clamping elements 11 and the guides 12, which are fixed by retainers 16 in the} cotton elements 11, break the jaws 13 and the workpiece 27 lowers onto The flange of the ogGravka 28. in the extreme lower position of the gripper 3, the nose of the latch 5, before sliding on the lateral surface of the frame 7, slides off the side surface and seizes the frame 7 behind the ledge. The lowering of the grip 3 is stopped.

The reverse of the drive is turned on and the gripper 3 starts to lift with the dispelled sponge 13. The sponge rises above the detail 27, dressed on straightening 28, the latch 5 with its protrusion

runs on the copier 32, which, disengaged from the engagement with the lower edge of the frame 7 latch nose. The frame 7 is released and, under the action of the spring, is pressed against the gripping shoulder. With

In this case, the rollers 9 converge from the copiers 6 and the pushers 8 of the spring 10 press the gripping elements 11 against the frame 7. The cuts 13 converge and after the gripper 3 returns to the initial position, the drive is switched off. Mandrel 28

With the part 27 mounted on it, it is moved to the subsequent technological operations, and an empty mandrel is fed into the device and the work cycle is repeated.

When transferring a device to work with another Size of assembled parts, it is necessary to fully develop magazine 25 from parts 27 of the previous size and then send a signal from the control panel to readjust the device. According to this: the signal in / store 25 is supplied with parts of another size, gripper 3 gets moving up (from position shown in Figs. 1 and 3). In the process of moving the fingers 23 enter into the holes 14 on the gripping elements 11 and pull out the clips 16 FROM the notches 15 on the bottom 12 and the leashes 20 of the nuts 19 enter the holes 22 of the jaws 13.,. The movement of the gripper 3 is stopped upwards and the drive 21 of the jaw changeover device 2 is turned on. The direction of rotation of the actuator depends on the size of the changing part 27. The screw 17, rotating in the supports 18, moves the nuts 24 along the guide 24, and the screws 20

move the sponges 13 ka the required distance. In this case, one of the recesses 15 on the guides 12 coincides with the hole 14 of the clamping elements 11, in which the clamps 16 are located.

The sensor signal (not shown) corresponding to a certain movement of the jaws 13, the actuator 21 stops working and the capture 3 starts

0 move to the starting position. In the process of moving, the jaws 13 are released from the leads 20, and the clamping elements 11 are freed from the fingers 23. Spring-loaded clamps 16 enter

5 in vkhemka 15 on guideways 12 and rigidly fix the guides 12 in the clamping elements 11. The gripper 3 returns to its original position and stops — auto-operative to work with the new part size 27. As needed, it is replaced with another size and mandrel 28.

: The application of the proposed inventive shadow allows reliability and shortens the auto operator's changeover time to work with various sizes of assembled parts.
