Description

(54) DEVICE FOR ASSEMBLING PRESSURE ROLLS OF SQUIRED MACHINES The image refers to the textile industry, in particular, devices for assembling the pressure rollers of spinning machines, and can be adapted for repairing cantilever roller rollers in roller workshops of spindle production. A device for assembling press rollers of textile machines is known, comprising mechanisms for feeding axes and cups of rollers to a drive disk horizontally mounted on a shaft, axle locking assemblies of axes mounted on a disk connected to a stationary copier, a device for lubricating rollers bearings and. knot nozzles / cups of rollers on them. The disadvantage of such a device is its low productivity and reliability due to the fact that the trays for feeding the assembly elements of the rollers together. With the assembly are mounted on the drive disk, which is used for loading the trays during operation of the device. The aim of the invention is to improve the reliability and productivity of the assembly of cantilever pressure rollers. This is achieved by the fact that the copier is installed under the disc, and the disc has supporting tphysms for placing the axes of the rollers located around its circumference, with each fixation unit containing a three-arm lever mounted on the disk, pressed by one shoulder to the copier. on the other shoulder is a spring-loaded finger to press the roller axis to the support prism, and on the third shoulder a resetter. In addition, the device contains a cut-off device mounted on the shaft above the disk and having openings for the passage of the roller parts to the fixing units and guides fixedly mounted between the retractors and the disk. The roller axle feed mechanism contains two inclined plates installed one at a distance from DR5PGOY, a spring-loaded stop and a spring-loaded pusher connected to the sifter by means of a copier, which is ejected onto a compartment; FIG. 1 shows a general scheme of the device; in fig. 2 is a sectional view of posture A in FIG. 1; on; FIG. 3 - vvd along arrow B in FIG. 2; in fig. 4 shows a sectional view at position B in FIG. I; in fig. 5 is a section of YYD in FIG. four; in fig. 6 shows the device in section in the D and E positions. one; in fig. 7 - section MF in FIG. 2. The device has a drive disk 2 mounted horizontally on the shaft 1, around the circumference of which six locking knots are mounted on the disk, and the axes of the total 3 push-fit rollers. Each fixation unit contains a three-arm arm mounted on the disc. The shoulder 4 levers, with the help of a single finger 5, presses the roller axis to the bearing prism of the 6th disc, and the carrier arm 7, which is discharged 7, serves to remove the working roller from the working zone. Under the disk 2 on the hub 9, the 10 was fixed at all, to which through the roller 11. with the help of the spring 12, the third arm 13 of the lever was pressed, which was driven. On earfy 1 above disk 2, an extractor 14 is fixed, having holes 15, for the passage of details of fixation. Shaft mounted on shariko; chassis 16 in the hub 9 of the disk 17, fixedly mounted on the housing 1 CTaiffiHbi .. device, and. receives a rotary rotation from an electric motor l 19 and a reducer 2O by means of a malt mechanism 21. D Between the cutter 14 and the disk 2, the guides 22 and 23 are installed to ensure the stability of the parts to be assembled at the moment of their arrival at the assembly sites .TSII- The guide 22 is intended for guiding the axes 3, and the guide 23 for the cups 24 ..,., The roller axle feeder contains two inclined plates 25, the distance between 1 which is larger than the diameter of the axis 26, the OUT of its outer diameter of the ball bearing 27. To feed the axles directly into the zone of action of the assembly pump - the feed is served by a spring-loaded stop 2 and a pusher 30 mounted in the guide cup 3 1 and under the action of the spring 32, which. - "-LCP. 1 -. ---,,-, -one-.---:."--., -,,- ..". --one

-.- i: r- ii; 3: SnSftS3 24 tremits cKiecTHTb pusher to the left, take the roller 33 mounted on it to the copier 34 fixed to the cutter 14. The feeding mechanism of stykanchik is shown in the form of a tubular tray 35 consisting of rods 36, interconnected by rings 37. The lower ring is located concentrically with the holes 15 of the shutter at the time of the disk. The device has working tools: axle feeder 28 3 (position A, Fig. 1), tool for lubricating roller liners (position I, Fig. 1) and cup nozzle assembly 38 on axis (position D, fig. 1). Working tools are mounted on the rods of pneumatic cylinders (in hell, not shown), synchronized with the movement of disk 2 as follows. That the movement of the rods is carried out at the time of the extruded disk. In the process of operation, the devices of axis 3, laid on inclined plates 25, under the action of their own weight slide into the zone of action of the pusher 30. The latter, in the initial position, is filled with the action of a spring, 32 occupies the leftmost position. When one of the holes 15 of the shutter comes to position A, the copier 34, acting on the roller 33, moves the DZ pusher to the right. The pressure axis is clamped between the pusher 30 and the spring-loaded stop 29, preventing untimely downward displacement of the axis to prevent it getting stuck on the slam-shutter 14 or the guide 22. The pusher 3O displaces the axis to position A, and the feeder 28 pushes it down. The neck 26 of the axle then appears in the support prism 6, and its ball-rim 27 in the guide 22, which keeps the axis from tipping over. At this moment, the copier 10 is in interaction with the roller 11 with its smaller radius, the shoulder 13 of the triple arm occupies the extreme right position (see Fig. 2), and the shoulder 4 is respectively left. Thus, the spring-loaded pin 5 does not prevent the axis of the neck from getting into the support prism. As soon as the disk 2 begins to rotate, the roller 11 moves to the surface of the chamber with a large radius, as a result, the 4iesro lever is deflected and the pin 5 fixes the axis in the bearing prism. At the moment of the next height of the disk, when the Axis falls in, the position And, produced, lubrication of its bearing assembly.

The lubricated shaft enters position B. At this point, the lower cup 24 is in the tubular tray 35, resting on the upper plane of the shut-off device 14, falls into the hole 15 and is placed on the upper part of the axis. In such a position, the cup-and-cup axis is transported by the disk to the D position, where the rod of the nozzle assembly 38, moving downwards, completely pulls the cup onto the axle bearing unit. Then, the assembled roller 39 moves to POSITION E, when approaching which the roller 11 of the triple arm interacts with the smaller radius of the copier. In this case, under the action of the spring 12, the lever is opened, turned, the spring-loaded pin 5 departs, releasing the roller 39, and the ejector 7 pushes it from the disk, sending it to the container 40.

The device allows reliable and high-performance lubrication and assembly of cantilever pinch rollers of spinning machines.
