Description

The invention relates to mechanical engineering, in particular, to tools for tightening clamps, in particular when fastening high pressure hoses to the connecting pipes and sleeves in hard-to-reach places.

 The purpose of the invention is to expand the technological capabilities of the clamping tool due to the fact that the clamped state is retained by the clamping tool without the support of the assembler, as well as fixing from turning and falling out of the tightening clamp bolt.

Fig, 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - clamping tool at the beginning of work; in FIG. 5, at the end of the work.

. The clamping tool (Figs. 1 and 2) includes a housing 1 with pins 2 rigidly attached to it, placed therein with the possibility of moving the jaw 3 with the grooves 4 in which the pins 2 are made. The sponges 3 are connected to each other by means of a hinge -, pa 5 and with a power screw 6. The flywheel 7 is screwed onto the threaded end of the screw 6. Case 1 is made with a stop 8, restricting in one direction the screw 6 around the axis of the hinge 5 connecting the jaws 3.

On one of the jaws 3 (figs. 1 - 3), plate 9 is rigidly fixed with screws 9 with a hole 11 and a gate valve 12 for closing the latter in order to fix the bolt 13 (FIGS. 4 and 5) tightening the clamp 14 at 12487822

fastening the hose 15 on the pipe 16.

The device works as follows.

When attaching the hose 15 (Fig.4)

5 3 nozzle 16, in one of the pro-clamp clamps 14, in the open state, install the clamping bolt 13 (Fig. 5). Then, hold the clamping tool to the clamp 14 with divorced jaws 3

10 (FIG. 4) and folded back with the power screw 6 (FIG. 1).

The head of the bolt (Fig. 5) is inserted into the hole 11 (Fig. 3) of the plate 10- and its position is fixed by a sliding gate.

15 valve 12. Then, moving the ball NIR 5 with screw 6, turn the latter with the flywheel 7 (Fig. 1) around the axis of the hinge 5 (to the position shown in Fig. 1 by thick lines).,

20, while the ends of the jaws 3 pick up the collar 14 at the points of bending of the lugs (FIG. 5), and since the final closure of the collar 14 requires a significant amount of force due to its rigidity,

25, further tightening of the latter occurs by screwing onto the screw 6 of the flywheel 7, in contact with the support 8 of the housing 1. In this case, the jaws 3 are closed30

c, leaning on pins 2.

After closing the clamp 14, the clamping tool is left at the place of the gripper and proceed to screwing the nut on the bolt 13 threaded into both eyes of the clamp 14.

To remove the clamping tool from the hose, it is enough to unscrew the flywheel 7 until a gap is formed between the latter and the stop 8 of the housing 1, and then turn the screw 6 around the hinge 5 and dissolve the jaws 3.

Claims (2)

1. A CLAMPING TOOL, comprising a housing with pins rigidly fixed thereon, movable therein, jaws pivotally connected to each other with grooves in which the pins are located, and a drive, characterized in that, in order to expand technological capabilities, the drive is one passing through the housing and connected at one end with a hinge connecting the jaws, a power screw and a flywheel mounted on the threaded end of the latter, and the housing is made with an emphasis restricting the movement of the screw. 2. The tool according to claim 1, characterized in that, in order to increase productivity, it is equipped with a plate rigidly fixed to one of the jaws with an opening and a slide gate.
