Description

Technical field

The invention relates to a roller bearing of a roller bearing when mounted in both cages at the same time.

BACKGROUND OF THE INVENTION

Up to now, the threads have been fed into the two bearings of the self-aligning bearings when assembled in the filler, especially one thread at a time. The rivets are conveyed to the filling point either by a guide, the movement of which is ensured by a ratchet with a stopper, or by the angled connections of the thread supply hoses in the guide disk of the thrust needles. The filling of the threads, in particular after one thread, is due to the stepwise rotation of the bearings. very low noise and low productivity. Moreover, in such a method of filling the rivets, at the beginning of the filling, the two half-cages are compressed only at one filling point, and in particular they open on the opposite side, causing poor cages of the rivets in the cages in other cage positions. During subsequent riveting, a portion of such poorly adjusted rivets is pressed between the cages at the point of imperfect filling, wherein the two cages of the bearing are not joined to each other by the circumference. Also, the fitting of the roller bearings when mounted in both cages at the same time by the pressure of the pressure needles in the guide disc is very imperfect, since any misalignment of the holes in the cages relative to the position of the pressure needles results in either incomplete filling of the threads of both the cages or damage. Missing unfilled rivets must then be refilled either manually or in a filling machine that can be filled separately after one thread and if the cage is damaged, the two cages with filled threads must be disassembled, the defective cages must be replaced with good ones and repeatedly correctly filled with threads. .

SUMMARY OF THE INVENTION

These drawbacks are overcome by the roller bearing thread filler according to the invention, comprising a sliding cylinder, guide rods, guide disc with angled connections of the thread supply hoses, a positioning fixture and a bearing holder, which is based on the sliding cylinder body fixedly connected by the upper holder through the main holder. a rod and guide rods with a lower bracket slidably connected by a pulling stop screw to a plate on which the bracket of the bearing positioning fixture is mounted, the plate being slidable on the guide rods in the plain bearings and on the main rod in the lower guide. Above the plate, on the guide rods, there is a sliding bottom plate with a fixed guide disc for the yarn connection hoses and thread guide sleeves evenly circularly positioned above all the bearing rivet holes on which the split collets with flexible outer rings are mounted by radial pins.

Above the bottom plate, on the guide rods, a sliding pressure plate with fixed needles is displaceable at one time in all guide plate stops and guide plates of the bottom plate connected to the bottom plate by means of a sliding rod, the sliding pressure plate screw and spring and pressure plate are fastened in the pressure plate. the plate is fastened by a clip to the piston rod of the cylinder displacement body.

The roller bearing of the roller bearings according to the invention allows a low-noise, high-quality and highly productive filling of all the rivets of both cotton bearing half-cages, which makes them particularly suitable for assembly automatic lines.

An overview of the figures in the drawing

The roller filler according to the invention is shown in cross-section in FIG. 1, FIG. 2 shows section A-A of the main and guide rods of the yarn feeder, and FIG. 3 shows a detail of the attachment of the split tongs in the guide disc of the yarn feeder.

Example of the β-revisedeniere invention

The roller bearing thread filler of FIG. 1 consists of a body of a sliding cylinder 6 fixedly connected by an upper holder 7, via a main rod 2 and guide rods 3, with a lower holder 25 slidably connected by a pulling stop screw 24 to a plate 11 on which the holder 20 of the bearing jig 21 is mounted.

The plate 1 is slidable on the guide rods 3 in the sliding bearings 5 and on the main rod 4 in the lower guide 4. Above the plate 1, there is a sliding bottom plate 10 with the guide disc 17 attached to the guide discs 17 and the guide sleeves 19. threads are uniformly circular over all the rivet holes of the bearing 22, on which split collets 28 with elastic outer rings 29 are fixed by radial pins 8 o Above the bottom plate 10, a pressure plate 9 with fixed needles 15 is displaceably disposed at the same time in all guide guides 16 of the guide disc 17 and guide bushes 27 of the lower plate 10c The pressure plate 9 is connected to the lower plate 10 by a sliding rod 23, the pressure plate 13 of the lower plate 10 with the spring 14 being fixed in the pressure plate S and the pressure plate 8 is fastened by a clip 12 on the piston rod 11 of the slide cylinder body 6th

The paired bearing 29 is inserted into the positioning jig 21 by the two inserted cages on the bullets 21. Each inlet hose 19 is fed upwardly into the split tongs 28 where it is retained by the head. After all the split collets 28 have been filled with threads above each thread hole of the bearing 22, the piston rod 11 is pulled out of the sliding cylinder body 6 and is moved along the guide rods 3 to the bearing 22 under its own weight or pulse from the stop screw 13 / bottom plate. 10 until the split collets 28 touch the bearing cages 22, thereby stopping its movement. By continuing to slide the piston rod 11 out of the slide cylinder body 5, the fixed needles 15 are pushed through the pressure plate 9 in the holes of the guide disc 17 until the fixed needles 65 partially extend the pivoted rivets from the flexible split pliers 28 into all the guide holes for the threads in the bearing 22. constant force on the weight of the device according to the invention. During the time of filling the threads into the guide holes for the rivets in the bearing 22, in the lower guide 4 and in the sliding bearing 5 of the plate 7 the guide rods 6 move with the main rod 2 interconnected by the upper holder 7 and the lower holder 25 against movement of the piston rod 11 until the lower holder 25 stops by the plate 1. By further extending the piston rod 11 from the body of the sliding cylinder 6, the filled threads are pressed by needles 16 fixed in the pressure plate 9 into the bearing holes 22 /

until the pressure plate 9 stops by a stop 66 when the ejection of the piston rod 11 from the body of the sliding cylinder 6 is completed. By retracting the piston rod 11 into the body of the sliding cylinder 6, the weight of the device in the lower guide 4 and in the sliding bearing 5 of the plate 1 moves the guide rods to the main rod 2 interconnected by the upper holder 7 and the lower holder 25 against movement of the piston rod 11 until the lower holder By continuing the movement of the piston rod 11 into the body of the sliding cylinder 5, the fixed needles 15 of the pressure plate 9 are pulled out of the holes in the guide disc 17, and the pressure plate 9 is moved to the starting position via the rod 25 to lower the plate. 10, the bearing 22 with filled threads is released in the positioning jig 21 and the bearing 22 is removed from the positioning jig 21, wherein the cycle of filling the yarns into 3 other bearings 22 is repeated continuously.
