Description

The invention relates to mechanical engineering, in particular to devices for assembling a coupling with a hose end. There are known devices for assembling the coupling with the end of the hose, containing a stand, radially movable crimping jaws and axially movable stem. However, these devices do not provide for crimping the braid at the end of the hose when the coupling is put on it, which significantly reduces the reliability of the assembly process and its performance. . The closest to the proposed technical entity is a device for assembling a coupling with a hose end, which contains a frame mounted on it and a movable body spring-loaded in the axial direction with swivel arms, swaged cams for crimping the braid and an axially movable rod, equipped with a drive translation. This device does not automatically slide the sleeve onto the end of the hose. Moving the hose in closed cams and installing the hose in the coupling after unclamping the cams is done manually, which significantly reduces the reliability and performance of the assembly. The purpose of the invention is to increase the reliability and productivity of the assembly process of the coupling with the end of the hose. The goal is achieved by installing an axially movable axially glass with shaped grooves, interacting with pivot levers between the bed and the body, rotating doors are installed on the body, and the stem is made with an axial bore and with notches under the said doors.

The drawing shows a device for assembling a coupling with a hose end, a slit.

The proposed device for automatic assembly of the coupling I with the end of a hose 2 having a metal braid 3 contains a frame 4, a cup 5 placed in a frame and spring-loaded spring 6 relative to it axially and equipped with an adjustable stop 7. Inside the cup 5 there is a housing 8 spring-loaded in the axial direction, the spring 9 relative to the cup 5. The rod 10 is located in the housing 8 and is provided with a translational drive (not shown). Two axle pivot levers 12, spring-loaded springs 13, are mounted on axis x 11 installed in housing 8, in the plane perpendicular to the axis of the housing and symmetrically to this axis. At one end of the levers are fixed cams 14 having the shape of a ring with an internal cylindrical surface for crimping the braid 3 and the outer conical centering of the coupling 1. At the other ends of the double-arm levers 12, axles 15 are fixed to rollers 16, which interact with the shaped grooves 17 of the housing 8. On the axles 18 located in the housing 8, in the plane perpendicular the housing axes and symmetrically to this axis are installed with the possibility of rotation of the flap 19, which are included in slots 20 on the stem 10. In the stem 10, in the plane perpendicular to the axis of the stem, symmetrically to this axis and parallel to the axis 18, the axes 21, which enter slots of the flaps 19. A clamp 22 is provided for fixing the hose to the assembly position.

The device works as follows.

In the initial position, the springs 6 and 9 are compressed, the cup 5 with its ledge rests on the bed 4, and the stem 10 rests on the housing 8. At the same time, the flaps 19 protrude from the slot 20 of the stem 10. The two-arm swivel levers 12 are rotated around the axes 11 so that the rollers 16 are located in the vertical part of the grooves 17, and the area between the cams 14 is sufficient for insertion of the hose 2 (shown by dotted lines). The hose 2 is transported to the area between the cams 14 and clamped by the clip 22. After this, the assembly process itself begins. Rod 10 moves

upward, it ceases to exert pressure on the housing 8, the spring 9 expands, since its rigidity is greater than the rigidity of the spring 6, and pushes upward the housing 8, and at the same time exerts pressure on the cup 5, preventing it from moving upwards. The two shoulders levers 12, connected to the hull of the axle II, move upwards. The rollers 16 move in the vertical part of the grooves 17. When the vertical part of the figured grooves transitions into horizontal movement of the rollers upwards, it becomes impossible, and since the axes 11 continue to move upwards, the two shoulders turn around the axes P. In this case, the rollers 16 enter into the horizontal parts of the figured the grooves 17, and the cams 14 are brought together to form an annular surface and crimp the sheath 3. After that, the movement of the body 8 relative to the cup 5 stops and as the rod 10 moves upwards, the spring 6 is expanded, securing Aulus glass 5 move upward together with the body 8 carrying the double-arm levers 12.

The cams 14 are at this time advancing on the unraveled part of the sheath 3 and compressing (calibrating) it according to their internal diameter until the stop 7 reaches the bed 4. The stop 7 is exposed on the glass 5 so that at the end of the stroke cams 14 rose above the braiding 3. After the stop 7 reaches the bed 4, the rod 10, continuing to move up, affects the axles 21 on the flaps 19 and spreads them, as shown in the drawing. After that, the upward movement stops. Clutch 1 is fed into the stem cavity, and s in the cams 14, centered on their outer conical surface. The rod 10 moves downwards, the axles 21 are able to act on the flaps 19 and rotate them around the axes 18, pushing them out of the walls of the rod 10, and the flap 19 with its beveled edges additionally centers the coupling 1. Go to the stop in the housing 8 and exert pressure on it, the rod 10 moves further along with the housing 8, and a stiffer spring 9 does not allow the housing 8 to move relative to the cup 5, moving it down to the stop in the frame 4. In this case, the cams 14 move down the sheath 3, and the flaps 19 act on the clutch and bait They put it on the end of the hose. When it reaches the stop, the cup 5 stops, the body 8 continues to move downward, compressing the clamp 9. As the body moves downward, the two shoulders levers 12 rotate around the axes 11 (the cams 14 release the lower edge of the clutch 1), and the rollers 16 exit the horizontal parts of the grooves 17. Continuing to move downward, the stem 10 through the flaps 19 will send the coupling to the end of the hose I, and the two shoulders levers 12 with the cams 14 move to their original position (shown by dotted lines). After this, the downward movement of the stem 10 is stopped, the clamp 22 is expanded and the hose 2 with the sleeve 1 mounted on it is withdrawn from the assembly area. The springs 13 serve to limit the free running of the two shoulders 12, causing the rollers 16 to be in contact with the outer surface of the grooves 17. The proposed device for assembling the clutch with the end of the hose allows fully automating the assembly process, which makes it more reliable and productive than known devices of this type. This is achieved primarily because it eliminates the use of manual labor during installation of the coupling on the hose and the assembly process is carried out in optimal conditions with a high degree of accuracy.
