Description

one

 The invention relates to the means of mechanization of electrical installation work, namely, devices for forming, a slip ring at the ends of stranded wires,

A device for pre-installation of electrical wires is known, comprising a ring-forming mechanism made in the form of a carriage with a rotating head, a spring-loaded sponge, a gear hub and a rod with a bevel lj. .

A disadvantage of this device is that it does not ensure the formation of a slip ring at the ends of stranded wires.

It is also known a device for forming contact rings at the ends of stranded wires, comprising a ring-forming mechanism, made in the form of two levers, a dropping mechanism, made in the form of a spring-loaded lever and a frame, on the front part of which there is a peg and a twisting mechanism 2j.

A disadvantage of the known device is the complexity of the design.

The purpose of the invention is to simplify the design. :

The goal is achieved by the fact that the device for forming a contact ring at the ends of stranded wires, comprising a ring-forming mechanism and a twisting mechanism installed in the housing and kinematically connected to the drive, is equipped with a drive-driven kinematically connected spindle that is axially reversible and rotational movement, the mechanism of forming the ring is made in the form of a fork fixed on the spindle in which it is movable in the radial direction. and installed spring-loaded fingers, each of which in the working position contacts one end to each other, and the other to the surface of the bore of the housing, while the twisting mechanism is designed as protruding. The housing is spring-loaded clamping jaws connected to sliders that are installed in the housing displacement in plane132

t, perpendicular to the plane of movement of said fingers, and kinematically connected with the spindle. Figure 1 schematically shows the proposed device for

forming a slip ring at the ends of stranded wires, a general view, in figure 2 - the mechanism of ring formation; Fig. 3 shows the working position of the links of the ring formation mechanism; figure 4 - section aa in figure 2, fig. 5 and 6 are sequential diagrams of the device operation. Forming device

a slip ring at the ends of stranded wires contains a ring-forming mechanism 2 mounted on the bed 1, kinematically connected with a pneumocylinder stem

3 and through the toothed sector 4 - with the stem of the pneumatic cylinder 5. The ring formation mechanism includes a housing 6, in the bore of the second with the possibility of axial and rotary movement. The spindle 7 is mounted. The working part of the spindle 7 is designed as a fork, in the side walls of which is movable in the radial direction direction set fingers 8 s

springs 9. In the bore of the case 6, bevels 10 are made interacting with the fingers 8. A protrusion is made on the end of one of the fingers 8, and a depression is located at the end of the other with a possibility of closing in the operating position. The spindle 7 has a slotted shank 11, the splines of which are fitted with shchestren 12. The shank 11 of the spindle 7 is connected by the pneumatic cylinder rod 3, and the gear 12 is engaged with the gear sector 4, kinematically connected with the pneumatic cylinder rod 5. In the middle part of the spindle 7 is made copying bevels 13 in contact with the sliders 14, located in the housing 6 symmetrically with respect to the spindle. The sliders 14 are spring-loaded to the spindle by the springs 15 and are connected to the clamping jaws 16, which are located in the grooves on the front part of the body 6. and can move counter with the sliders 14 towards the spindle 7 under the action of the springs 15.

A device for forming a slip ring at the ends of stranded wires operates as follows.

The stripped end of the wire 17 is pushed into the slot of the plug of the spindle 7, the pneumatic cylinder 3 is turned on, the rod of which moves the pin 7 to the bore of the housing 6, as a result of which the finger 1 8. under the action of the bevels 10 of the housing 6 c ykayutc and overlap the slot of the fork of the spindle-7 7, forming slotted a closed loop around the wire 17. Docked finger 8 ,. moving along with the spindle 7 further, drag the end of the wire 17 and pull it between the jaws 16 ,. giving it a form of staples. With the further movement of the spindle, the slides 14 under the action of the springs 15 are displaced along the coping bevels 13 of the spindle 7 and move the clamping jaws 16 towards each other. The clamping jaws 16 are closed and the ends of the wire are compressed, completing the formation of a loop. The pneumatic cylinder 3 of the longitudinal movement of the spindle 7 is turned off, and the pneumatic cylinder 5 is turned on, the rod of which is through sector 4, gear 12 and splines

64813.4

the shank 11 rotates the spindle 7. The undocked fingers 8 twist the previously formed ring, the ends of which are held by the ea5 pressing jaws 16, creating a ring on the wire with an inner diameter equal to the outer fingers 8. Next, an air cylinder

5 is turned off, pneumatic cylinder 10 is turned on, the rod of which, moving in the opposite direction, returns the spindle 7 to its original position. In this case, the clamping jaws 16 move apart and release; the ring is pressed from the clamp, and the fingers 8 release the formed ring.

The implementation of the mechanism of the ring of the ring in the form of a fork with spring-loaded fingers fixed on a 2Q spindle, and the mechanism of twisting in the form of an interaction with the spindle of the clamping jaws and the location of these mechanisms in 5 perpendicular planes allows to simplify the design.
