Abstract

This invention relates to mechanical assembly production, in particular, to devices for assembly by pressing. The purpose of the invention is to expand technological capabilities and improve quality by ensuring the assembly of additional component parts (D) and limiting the pressing forces by a predetermined value. A ring 23 is mounted on the rod 13, and a base D 24 with bolts 25 is mounted on the lodgement 10. Press presses the mandrel 5 and through the bolts and D 24 on the lodgement, which is retracted and the ring 23 is pressed in. At the end of the lodgement stroke, the limiter rests against the base, after which the punches 21 press in the bolts 25. Due to the presence of the limiter and the elastic element 14, damage to the assembled E is eliminated. The outer ring of the upper bearing and other components D are assembled in a similar way when using other mandrels mounted on a pivotal traverse 3. 7 Il.

The invention relates to mechanical assembly production, in particular to devices for assembling by pressing in assemblies of units such as automobile brake drums.

The aim of the invention is to expand the technological capabilities of the device and improve the quality of the assembly by allowing the device to assemble additional components such as bolts and by limiting the pressing force to a predetermined value.

FIG. 1 hyzhasano assembly device, general view; } ia of FIG. 2 is a view A of FIG. one; in fig. 3 view B in FIG. one; in fig. 4 is a view of B in FIG. one; in fig. 5 section G-D in FIG. four; in fig. 6 is a section D - D in FIG. 3; in fig. 7 - location of the elements of the system but interrelations during the work.

The device contains a base 1 and a press-in mechanism in the form of a fixed rack 2 mounted on it, a cross beam 3 mounted on the rack with the possibility of rotation and spring-loaded relative to the base by an elastic element 4. The cross bar 5 8 for various technological operations with the ability to interact with the pressure element of the press (not shown). On the base, a device for mounting the base and component parts, made in the form of a gesture, fixed on the base of the hollow cylindrical guide sleeve 9, the stop mandrel and the cradle I) for the base part, is also mounted. The thrust mandrel is made in the form of a support 11 fixed in a direction of the sleeve 9 on the thread with the possibility of adjusting movement and fixing with a nut 12 the centering rod 13 installed with the possibility of axial movement of the guide sleeve and the elastic element

14, located between the ends of the rod 13 and the support 11. In the wall of the guide sleeve, the rifle is a limiting rod

15. The fixture 10 for the base part is made in the form of a support sleeve, mounted on the outer surface of the guide sleeve 9, mounted for axial movement relative to the latter and spring-loaded relative to the base by springs 16, mounted on rods 17. At the upper end of the support element , 1, the guide holes 18 for the press-in bolts are not. A movement limiter 19 is fixed on the bottom end of the patch 10 with the possibility of interaction with the projection 20 of the base.

The pressing mandrel 5 for assembling the bolts with the base part is made with punches 21 supported on the end face of the elastic element 22.

The assembly device operates as follows.

Outside (x ring 23 of the lower tapered roller bearing is mounted on the bearing surface of the centering rod 13, and the base part 24 is a drum mounting surface

 the cradle 10, the bolts 25 are inserted into the guide holes 18 of the cradle.

A pressing arbor 5 with punches 21 is mounted coaxially with the tool, iioc. Ie what the drive is turned on

press fitting. The yoke 3 then moves downward, compressing the spring 4. The centering rod 13 enters the hole of the mandrel 5, ensuring the alignment of these nodes. The force of the press through the punches 21, the bolts 25 and the part 24 is transferred to the cradle 10, which is lowered, compressing the spring 16. Since the force required to press in the ring 23 is much less force to press in the bolts, the ring is pressed into the base part. Move

0 bed 10 occurs before contacting limiter 19 with vystugyu.m 20 bases. The amount of deformation of the elastic element 14 is set in advance by moving the adjustable support 11, which allows

It does not limit the maximum pressing force and protect the assembled parts from damage.

After the stop of the limiter 19 into the base, the punches 21 press the bolts 25 into the base part 24. In this case, the annular elastic element 22 compensates for the difference in bolts in length.

At the end of the press-in, the pressure element of the press, and after it, under the action of the springs and the yoke 3 with the mandrels, as well as the cradle 10 and the centering rod 13, return to their original position. The llotiopoTOM traverse 3 is 90 ° above the fixture, and another recessing device (mandrel 6) is installed and the pressing of the 1 outer ring 26 of the upper pivot holder is carried out. At the same time, the presence of the elastic element 14 and the limiter 19 makes it possible to eliminate the influence of the pressing force on the BCTaB. ieiiHoe in the base part ring 23.
