The invention relates to mechanical engineering, in particular to devices designed to install tension springs on parts of an assembly to be assembled.

The purpose of the invention is to improve the performance of the device.

The goal is achieved by partially automating the installation of the extension springs. 1 In FIG. t Shows a device for installing tension springs in. (the beginning of the installation of the springs, section J in Fig. 2 is the same after the installation of the springs has been completed.

The device for the installation of tension springs consists of a body 1 mounted therein with the possibility of axial movement of the rod 2, a support collar 3 mounted on the body 1 and; weaving the thrust surface, the yoke 4 mounted on the stem 2 of the levers 5, interacting with the thrust surface of the support collar 3, having each gripping hook 6 at one end and mounted on the yoke 4 by means of hinges 7.

The surface 8 of the part 9, on which the springs 10 are mounted, is used as an abutment surface of the support collar 3.

Pneumatic cylinder 11 is installed on the housing 1.

The initial position of the device is when the rod 2 is extended from the pneumatic cylinder 11.

The device works as follows.

The part 9 on which the springs 10 are mounted is placed in the support collar 3. One eye of each spring 10 is put on one of the hooks of the part 9, and the other on the hook 6 of each lever 5. Having thus installed

 under the action of the moment from the force of the spring 10, they rotate with the bone of the clip 3, freeing their eyes. 2 Il.

The required number of springs 10, the number of which is equal to the number of levers 5, includes a pneumatic cylinder 11 for retracting the rod 2. The rod 2 is mixed relative to the part 9 together with the cross member 4 and the levers 5. At the same time, the springs 10 are expanded and the levers 5 force spring relative to the hinge 7, pressed against the surface 8 of the part 9 and move along it. When the levers 5 come out of contact with the surface 8, they are rotated under the action of the torque from the force spring due to the difference in distances A and B (Fig. 1), while releasing the eyes of the springs 10 from engagement with the hooks 6 , and the lugs are included in other hooks of I Parts 9 (Fig. 2).

Then, the part 9 with the installed springs 10 is removed from the support casing 3. The rod 2 is pushed out of the pneumatic cylinder 11, the device is driven to its initial position.

Claims (1)

Invention Formula A device for installation of tension springs, a contained body mounted therein with the possibility of axial movement of a rod with a gripper, which is characterized by the fact that, in order to increase productivity, it is provided with a support sleeve mounted on the housing and designed to rely on the part on which are installed springs and having a thrust surface, and the grip is embodied in the form of a traverse and levers that interact with the thrust surface of the support cage, having each gripping hook at one end and mounted on the traverse Hinge joint. / Editor V.Danko Order 430/15 Compiled by V.Matvienko Tehred L.
