(54) INSTALLATION FOR MOUNTING FLAT SPRING RINGS

I

The invention relates to a machine tool and can be used in the assembly industry as a stationary and replaceable tool d; 1 for gripping and mounting outer flat spring rings on shaft-like parts using automatic devices.

A device for gripping and assembling flat spring rings is known, which includes installation pins, an ioduster stop and an elastic deformation mechanism of the ring, which is made in the form of a cylindrical body with diametrically positioned longitudinal grooves and a coaxially mounted sleeve with figured windows, and the sleeve and body are interconnected by means of a pin, connected with drive 1.

The disadvantage of this device is the impossibility of automatic installation of outer spring rings of various sizes directly into a given groove of the shaft.

This goal is achieved in that the device is equipped with a nozzle, a fixed sleeve with pushers and an adjustable stop.

and the bracket installed with the possibility of moving and carrying the spring-loaded stop.

FIG. 1 schematically shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one.

The device for gripping and mounting the flat spring rings of the rings includes a housing inside which are connected with a drive (not shown in the drawing) pull 2 with a pin 3

10 and the sleeve 4, resting on the bearing 5, to which it presses springs 6. On the diametrically opposite sides of the sleeve 4 there are two figured windows 7, including inclined 8 n horizontal 9 and 10

15 plots. The ends of the pin 3 through the figured windows 7 inlet t & longitudinal grooves And, made on diametrically opposed; 1zh the first sides of the housing.

Claims (1)

A nozzle 12, a movable stop 13, two adjustable pushers 14 rings and a spring-loaded pin 15 for mounting the mounted ring 16 are fixed to the bottom end of the sleeve 4; a sliding bracket 17 is installed in the transverse grooves of the case, bearing a spring-loaded yiiop 18. On the outer cylindrical surface of the case 1 the bar 19 is fastened with a second pin 20 for installing the mounted bar 16 and the bar 21, which serves as a barrier for rotating the sleeve 4. A return spring 22 is attached to the bar 21 and the nozzle 12. A device for gripping and mounting the flat spring bridges The unit works as follows. After installing and securing the eGe in the executive body of the automatic assembly magnatulator (shown in the drawing), the device is moved to the gripper of the mounted ring 6. The device is placed over the pre-oriented gripping ring and lowered to the front of the nozzle 12 and the bar 19 of the face of the ring 16. In this case, the installation pins 15 and 20 enter into the holes in the eyes of the ring .16. When moving the cable 2, connected with the drive upwards, the pin 3, interacting with the longitudinal seams II in the case and the inclined part of the 8 figured windows 7 of the sleeve 4, rotates the last case of the case, thereby expanding the ring 16 and the return spring 22. When The ring 16 is clamped in the recesses on the installation pins x 15 and M and the spring-loaded stop 18 and is brought under two adjustable pushers 14e. Then the device moves to the shaft fixed in the assembly tool (not shown), and lowers, pulling on, unclenched. e ring 16 on the shaft. Lowering stops when the ring 16 approaches the edge of the groove. During the subsequent movement of the gigabyte 2 down, the pin 3, moving in the longitudinal grooves II of the housing 1, is detached from the inclined part of the 8 figured windows 7, making it possible for the sleeve 4 to rotate under the action of the spring 22 and the cola 16 that is designed to cover the shaft. Continuing downward movement, the pin 3 reaches the horizontal sections of 9 figured windows 7, which serve as a stop, and moves the sleeve with the nozzle 12, which with the help of two adjustable pushers 14 pushes the mounted ring 16 into the shaft groove, releasing the adjusting pin 20. Setting pin 15 The height of which also exceeds the thickness of the ring 16, abuts against the part previously mounted on the shaft and underneath, and is embedded. When the tool moves upward, the locating pin 15 exits the mounted ring 16, and the sleeve 4 under the influence of the springs 22 and 6 rotates and moves in the axial direction (upwards relative to the housing 1), returning to its original position, which the pin 3 is located on horizontal sections 10 of windows 7. This position of the working elements of the device corresponds to the beginning of the next cycle. The invention allows to diversify the technological capabilities of the equipment and gives a significant economic effect. Claims An apparatus for mounting flat spring rings comprising mounting pins, a spring-loaded stop and Mexaiffl3M elastic deformation of a ring, made in the form of a cylindrical body with diametrically positioned longitudinal grooves and a coaxially installed sleeve with figured windows, and the sleeve and body are kinematically connected, and the body has matching kinematically spacers. A coupled drive, characterized in that, in order to expand technological capabilities, it is provided with a nozzle, closed at the hub with pushers and re a guided stop, and a clip, mounted for movement, and carrying a spring-loaded stop.
