(54) MACHINE FOR ASSEMBLING KNOTS

The invention relates to assembly process equipment and HianaeTCH for the assembly of hydraulic pipe connections and lubricants.

A known machine for assembling assemblies comprising a profile copier, boot n control devices, assembly mechanisms located on a multi-position rotary table, and a drive 1.

The purpose of the invention is to increase nro-Sustainability.

To achieve this goal, the sleep machine is equipped with a face plate with radial grooves and spring-loaded arms with rollers that interact with the profile copier, with the arms hinged on the turntable and mounted in the radial grooves of the face plate with the possibility of movement.

FIG. 1 shows a machine, side view; in fig. 2 - the same, top view; ka fig. 3 - one of the assembled nodes.

The machine consists of a bed 1, on which is placed an 1-type rotary table 2, kinematically connected by means of a shaft 3 to an electromechanical drive 4, communicating with the help of a Maltese mechanism (not shown in the figures) cyclic rotation to table 2.

Shaft 3 is mounted in column support

5, which is fixed profile copier

6. On the base 1, the traveling cam 7 and the support 8, equipped with a roller 9, are fixed.

The upper part of the spring-loaded spindle 10 is made in the form of an end coupling half 11, and the lower part - in the form of an elongated pinion 12. The rotation of the spindle 10 is transmitted from an electromechanical drive

10 4 with the help of gear 13 and 14, while on the shaft 15 H 13 of the gear 13 is fixed cam 16, interacting with roller 9.

On the turntable 2, there are six assembly mechanisms 17, made in the form of component heads containing spring-loaded quill, with rollers 18 interacting with the traveling cam 1. Inside the pynols, there is a welded roller, the lower part of which is designed as an end coupling half 19, which interacts with the face hemipluter spindle 10.

On the turntable 2, spring-loaded levers 20 are provided, equipped with rollers 21 interacting with a profiling copier 6, which provides the possibility of radial movement of the levers 20 in the slots of the faceplate 22 rigidly connected through a rack .23 with a table 2. On

30 faceplate 22 made sockets 24 DL

installation in them buildings assembled nodes.

The assemblies of the soybean pipelines contain the following (parts: body 25, nipple 26 and nut 27 (see Fig. 3).

The following devices are also installed on the frame 1 in the technological sequence: a vibrating bunker 28 with a feeder 29 for issuing nuts 27 to the component head of the assembly mechanism 17 (see Fig. 2 pos. I); a device 30 for monitoring the presence of nuts 27, made in the form of a mechanical probe (see FIG. 2 pos. II); vibrating hopper 31 with a feeder 32 for the single issue of nipples 26 in the kit, his head (see Fig. 2 pos. III); a device 33 for controlling the presence of nipples, also made in the form of a mechanical probe (see Fig. 2 pos. IV); an assembly position (see Fig. 2 pos. V), on which a spindle unit 10 is mounted, which provides screwing of the threaded parts; tray 34 (see. Fig. 2, pos. VI), ensuring the removal of the assembled node.

The machine works as follows.

When the electromechanical actuator 4 is turned on by means of the Maltese mechanism, the shaft 3 rotates the rotary table 2. After turning the / S rotation, the six position table 2 stops (elevation).

During the stand-up of table 2, the nut 27 of the assembly to be assembled is loaded into the torpedo wrench of the component head at position I (see Fig. 2), and also the nipple 26 at position III, which is centered with the rod of the flathead of the component head. At the same time, in position IV, the housing 25 of the assembled assembly is installed in the groove 24 of the washer 22, the lower edge of the groove 24 engulfs the groove 35 of the housing, and the upper edge of the groove 24 contacts the outer profile of the housing 25, thereby securing it from axial displacement and from turning around the axis.

From the electromechanical actuator 4, a constant rotation is also transmitted through the pinions 13 and 14 to the cam 16 and the spindle 10.

During the subsequent rotation of the table 2, the next completing head with the loaded parts moves to the fixed position V. Before this, positions II and III control the presence of loaded parts using the devices 30 and 33 (mechanical probes), and the complementary head the result of the interaction of the roller 18 with the traveling cam 7 is moved to a certain height and after stopping the table 2 is set coaxially with the spindle LO. The rotating spindle 10 as a result of the interaction of the roller 9 with the cam 16 and under the action of the spring moves vertically, with the end coupling half 11 of the spindle 10 entering into the coupling with the front coupling half 19

drive roller component head.

The drive roller of the completing head, having received rotation and moving up, provides screwing of the threaded surfaces of the nut 27 and the body 25 installed in the nest 24 of the faceplate 22, after which the rotating spindle 10 and the completing head return to their original position (the spindle 10 as a result of

interaction of the roller 9 with the cam 16, and the component head under the action of the springs of the quill holes), and the assembled unit remains in the slot 24 of the faceplate 22. With the next turn of the table 2, the component head

moves from assembly position V to position VI.

One of the six spring-loaded arms 20, when the roller 21 interacts with the profile of the copier 6, moves into the groove

faceplate 22 in the radial direction and pushes the assembled assembly into tray 34. This completes the assembly cycle.

The implementation of the described invention provides for increased productivity.
