(54) DEVICE FOR ENLOGGING AND UNLOADING THREADED PARTS

37

with respect to the driver, the sleeve 3 with the groove 4 with the internal thread 5 and the lock 6, which is included in the ring groove of the driver 2.

The device is provided with an additional threaded mechanism 7 for vertical winding 2 with a thread 8 corresponding to the thread pitch of the part to be unscrewed 9, and the housing 1 is made with a groove 10 on the side of the winding 2, in which the nut 11 is fixed from rotation by a retainer 11 and nut 12 of the vertical mixing mechanism 7 three grooves 13. BopoToS contains marks corresponding to the basic positions of the threaded part 9. Each groove 13 is complete within the HO, Vorotok 2 has also handles 14 and sockets 15, in which the spring-loaded torus is marked. New keys 16, ending with shanks 17. Case 1 has a latch 18, fixings from rotation of the sleeve 3, the fitting cylindrical part 19 with the limiting collar 2O, the limited flange 21 and the handle 22. The threaded part 9 is screwed into the product 23 and fixed by bolts 24 .

The device works as follows.

Body 1, by the arms 22, is lowered into the opening above the repaired zpelk & l until the cylindrical part. 19 is not worn on the product 23 and the collar 20 is not with the child on its end. The restriction flange 21 fixes the position of the housing 1. Vorotok 2 together with the sleeve 3 and the nut 12, the upper end of which is set to the Removing mark, by the handles 14: is installed in the housing 1, orienting the groove 4 of the sleeve 3 so that the retainer 18: falls into the groove 4. By turning the knob 2 within a turn, the axes of the socket wrenches 16 are aligned with the axles of the bolts 24. When the axes coincide, the turn of the knob 2 is lowered and the shanks 17 of the keys are raised, compressing the springs. When installing knob 2 nut 12

opened in the groove 10, its lower end rests on the collar of the housing 1, and the retainer 11 falls into the groove 13. Between the collar 2 and the end of the threaded part

9, a gap of 1.5-2.5 pitch of the thread 9 of the part 9 arises. When the keys 16 are turned, the keys of the keys rotate through the heads of the bolts 24, and the keys fall into place. The keys 16 are turned with the help of the shanks 17 and the bolts 25 are turned one or two turns, releasing the threaded part 9 from locking. By turning the knob 2 by the handles 14, the threaded part 9 of the product 23 is unscrewed. In this case the threaded part is screwed into the threaded sleeve 3, and the knob 2 is intertwined by the same pitch as the threaded part. Thereby, a gap is maintained between the knob 2 and the end of the threaded part.

The termination of the unscrewing process of the threaded part 9 is judged by the marks on the crank 2, the distance between which is equal to the thickness of the threaded part. The mounting of the screw part 9 is performed by the same operations. However, the upper end of the nut 12 is installed on the mark Installation. The device for screwing and screwing out the threaded parts eliminates the axial impact on the threaded part 9 and the product 23; thereby increasing the reliability of the device.

Claims (1)

Invention Formula Device for wrapping and bolting of threaded parts according to ed. St. NO 539754, characterized in that, in order to increase reliability, it is equipped with a threaded vertical movement mechanism with a pitch corresponding to the thread pitch of the part, and the housing is threaded from the side of the driver, in which the vertical movement mechanism is located and secured against rotation.
