Abstract

This invention relates to a mechanized tool. The purpose of the invention is to increase productivity. The screwing-in and pressing-in device comprises a frame 1 mounted on it with the possibility of stirring, a plate 2 with spindles 3 placed on it, each having at one end spring-loaded head along the axis 4 of a turnkey key 4 and a maximum torque clutch 6 with the last drive 7. On the frame 1, the hydraulic cylinder 15 is fixed with a rod for interaction with the plate 2. On the plate 2 a punch is fixed with a safety device 20 mounted on it. The product is installed in the device 24. The safety device 20 is installed pressed Detail. The actuator 7 and the hydraulic cylinder 15 are turned on. The plate 2 with rotating spindles 3 and and heads 4 together with the punch and catcher 20 moves to the product, pressing in the part. At the same time, the heads 4 are engaged with the nuts of the tightened threaded joint and tighten the latter. At the end of the tightening, the clutches 6 are actuated, by which time the pressing ends. 4 il. a / 23 CO 05 th O5 05 9 of 1

Description

5, the safety device 20 and the press-fitted part installed therein move toward the assembly unit 23 and begin to press the part into the assembly unit 23. At the same time, the turnkey heads 4

f. comes in contact with the ends of the wrapped nuts (not shown), compressing the spring 5. As soon as the profile of the socket of the head 4 is aligned with the faces of the nut, the head 4 under the action of the spring 5 will mix in the axial direction and reliably cover

The invention relates to a mechanized tool for assembling threaded connections with simultaneous pressing of various parts and can be used in various industries.

The purpose of the invention is to increase productivity by combining an operation by a group of tightening threaded connections and pressing in parts.

FIG. 1 shows a screwdriver and press fitting, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2

A screwdriver and a lock nut, by tightening it. To the broom contains frame 1, the set-in end of the pressing-in ends

it is able to move the plate 2. and tighten the nuts, while at the same time with the spindles installed in it 3. the maximum tightening torque of the thread- At one end of each spindle there are 3 different joints with each of the spindles The corresponding clutch 6 of the distortion and relative movement of the torque moment and the spindle 3 with a turnkey 4 clever head 4, spring-loaded in the axial direction by the springs 5, and the clutch 6 of the limiting moment on the other, kinematically connected with the actuator 7, turn around. and The maximum torque clutch 6 includes a leading half coupling 8 mounted on the spindle 3 rotatably, made in one piece with an asterisk 9, and mounted on the spindle 3 rotatably rotatable and relative to the head 4 of the wrench, release the axial axial moving the driven screwed joint of the threaded joint, the pressed part remains on the assembly unit 23, and the safety device 20 under the action of the springs 11 returns to the initial position. Assembly unit 23 is removed.

14 with each of the sprockets 35 of the device 24 and in its place installed 9. A hydraulic cylinder 15 is fixed on the frame 1, a new product is being poured, to be assembled

stops. In the process of pressing the part, the safety device 20, abutting against the assembly unit 23, moves along the punch 19, compresses the springs 21 and does not prevent the movement of the pressed part.

At the end of screwing in and pressing in, they switch the hydraulic cylinder to reverse. The hydraulic cylinder rod 16 returns plate 2 to its original position, with

the coupling half 10 is axially spring-loaded to the driving coupling half 8 by springs 11. An asterisk 13 is fixed on the output shaft 12 of the actuator 7, the connected chain 16 of which is connected to the plate 2 through the flange 17 and the glass 18. On the flange 17 there is a punch 19. On the punch 19 with the possibility of longitudinal movement of the installation-. The flap catcher 20 is axially spring-loaded with springs 21. The catcher's stroke is limited by studs 22 fixed by one ends in the catcher 20 and freely placed by the other ends in the punch 19.

ke. Then the loop is repeated in the sequence described above.
