Description

The invention relates to a mechanized tool, namely to wrenches for round nuts, and can be used in any industry for assembling threaded connections.

A device for screwing products with round nuts, comprising mounted on a rack a power cylinder with a stop and a housing with a locking mechanism 1, is known.

A disadvantage of the known device is the low productivity of the assembly process.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that the hydromechanical key for round nuts, containing a sleeves-mounted cylinder and a housing with a locking mechanism, is equipped with an adjustable stop mounted on the rack in the form of a lever, and the locking mechanism is designed as a rotary disk with spring-loaded dogs, a latch and two spring-loaded two-arm levers kinematically connected with each other, with one of the two-arm levers in the upper extreme position interacting with the support on the stand, and in the lower extreme position the latch interacting with a focus actuator.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 - the initial position of the body with gripper; in fig. 5 shows a section B-B in FIG. one.

The hydromechanical key for round nuts contains a rack 1, a hydraulic cylinder 2. pivotally closed 1 on a rack 1 and a housing 3 with a groove 4, a gripping mechanism 5, made with two female spring-loaded pawls 6 mounted in the housing 3, connected with a rotating disk 7 with two two shoulders levers 8 and 9, pivotally interconnected and spring-loaded spring 10 through the plunger 11. The locking mechanism 12 includes a lock 13 with a groove 14 and a latch 15, spring-loaded in the direction of the housing 3, the mechanism opens 16, the latch 17; mounted on the housing 3 and spring-loaded, the stop 18, made in the form of a two-armed lever with adjustment knobs with a screw 19 and mounted on a rack 1, the stop 20 mounted on the hydraulic cylinder 2. The hydraulic cylinder 2 has nozzles 21 and 22 for supplying fluid and pores (not shown ) with HITOKOM 23.

The opening mechanism 16 includes an eccentric 24, which is spring-loaded toward the housing 3 and the handle 25.

Key hydromechanical for round nuts works as follows.

In the initial position (Fig. 4), the dogs 6 are divorced, the spring 10 is compressed by the plunger 11, called 14 of the lock 13 is aligned with the groove 4 of the housing 3, 9 is fixed by the latch 17.

The housing 3 is put on the shaft 26, the lock 13 is rotated by 90 °, and this position is fixed by the lock 15.

When fluid is supplied to the hydraulic cylinder 2 through Ptutzer 21, the piston (shown) with the rod 23 moves downward and turns the body 3 around the axis Ba: ia 26. At the end of the stroke, the latch 17, abutting against the stop 20, os1 "), leans the lever 9.

The lever 8 of the node by the action of the spring 10 turns the disk 7, the cat () p1) 1Y, acts on the dogs 6, inserts them into the slot, (or holes) of the nut 27.

When the fluid in gidrotsiliNdT.r

2 Through fitting 22, a piston with HITOKOM 23 shifts up, turns the case

3 with pawls 6 and nut 27 around the axis of the shaft 26. At the end of the upward movement, the lever 9 pushes against the stop 18 with the adjusting screw 19, compresses the spring 10 through the reel 11, acts on the lever 8, turns the disk 7. The latch 17 fixes this position of the lever 9, and pawl 6 release the lock 27. The nut tightening cycle repeats, as described by Bbinie.

After a given set of cool times (it is regulated by the fluid pressure in the hydraulic system), the cycle is stopped. The deletion is removed in the guide. With the eccentric 24 of the mechanical mechanism of the opening 16, the lever 8 is turned and the disk 7 is turned. The dogs 6 release the nut 27. Turning the lock 13 together 10 t and the grooves 14 of the lock 13 and the groove 4 of the housing 3. Fix this position with the lock 15. (the body 3 hangs from the shaft 26 .

The process then repeats.

Using the design of a hydromechanical key for round nuts in comparison with the known design of a key for round nuts ensures an increase in labor productivity by combining the working operation of screwing the nuts on with the operation of manually assembling the assembly outside the device due to the mechanization of the assembly process.
