Description

one

The invention relates to riveting works in the branch industry, in particular, to devices for assembling riveted roller bearing separators with riveting.

A device of the type of a plow for riveting rolling bearing cages is known, comprising upper and lower riveting tools movable one against the other, a pre-orientation mechanism with supports for cages and trays for loading and unloading bearings 1.

The disadvantages of these stamps are the complexity of the design, the possibility of using them only on special equipment and for riveting bearings with an odd number of balls.

The purpose of the invention is to show how the assembly is worn and the performance of a device for riveting rolling bearing kite separators with an even and odd number of balls.

This goal is achieved by the fact that the device for riveting kite separators of rolling bearings, containing upper and lower ring riveting tools movable relative to each other, a pre-orientation mechanism with supports for the separator and trays for loading and unloading bearings, is equipped with a spring-loaded cradle mounted on the lower riveting tool along its axis. for the bearing, with holes in the cradle supporting the mechanism of the preorientation. In addition, the device is equipped with a limit switch, and the top riveting tool has a flag for giving a command to riveting, affecting the final switch, while the trays for loading and unloading bearings are flush with the spring-loaded lodgment.

FIG. 1 schematically depicts a device, a general view, in FIG. 2 shows section A-A in FIG. on fig.Z - the position of the supports and the lower riveting tool relative to the bearing; in fig. 4 - top position

5 tools relative to a riveted bearing; in fig. 5 - the same in the riveting process.

The device for riveting consists (Fig. 1 and 2) of the upper I and I.

Claims (3)

0 2 ring riveting tools. which are centered one relative to the other with guide sleeves 3 and columns 4. The upper riveting tool 1 is movably held by electromagnet 5 in housing b rigidly fixed in the movable part of the press, and the flag 7 is turned on to press on riveting when the separator is correctly oriented. In the same plane with the upper edge of the lower riveting tool, trays 8 and 9 are installed for loading and unloading bearings and a spring-loaded cradle 10 held on columns 4 and springs 11. The lower riveting tool 2 has supports for the mechanism of preliminary orientation on springs 13 for fixing the separator along his protrusions Lower riveting tool 2 gesture attached to the foot of the press. The device works as follows. Bearing 8 is fed to bearings in a riveting area, for example, with a rod of a pneumatic cylinder, equipped with an element of pre-orientation of the separator relative to riveting tools. Pre-orient the spindle in the riveting zone on the spring-loaded lodgment 10, while the upper riveting tool 1 is held by the electromagnet 5 in the upper position in the housing 6. When the electromagnet is de-energized, the upper riveting tool 1 under its own weight lowers onto the tongue under the body, against the separator memory and the heads of the rivets, followed by the flagging of the 7th command through the limit switch (BVK) to activate the press. The mobility of the upper riveting tool 1 provides additional orientation of the separator, and the BVK and flag 7 exclude the failure of the riveting tools, since if the separator is not oriented correctly, the flag 7 will not reach the trigger position of the BVK and the riveting will not occur. The process of forming the rivet heads (Fig. 5) is performed after additional separator orientation by lowering the press ram and hitting the upper riveting tool 1 with the casing 6 at the lower position of the cradle 10 and the semi-separators pressed to each other by means of the supports 12. At the end of the riveting, the device elements occupy the original position after the bearings are replaced by moving them along the chute 8, the cradle 10 and unloading the chute 9, the cycle repeats. The device for riveting can be used both in a separate automat and in the form of a device, which can provide automatic riveting on universal presses. Claim 1. Device for riveting kite separators of rolling bearings, containing upper and lower riveting tools movable relative to each other, a pre-orientation mechanism with supports for the separator and trays for loading and unloading bearings, in order to improve the quality of assembly and productivity, it is equipped with a spring-loaded lodgement mounted on the lower riveting tool along its axis for the bearing, with holes in the lodgment for supporting Pre-orientation mechanism. 2. Device POP.1, characterized in that it is equipped with a limit switch, and the upper riveting tool has a flag for giving a command to the riveting acting on the limit switch. 3. The device according to Clause 1, that is to say that the trays for loading and unloading bearings are located flush with the spring-loaded lodgment.
