Abstract

A device for laying wire on a coil comprising a coil rotation drive located in the housing and a reciprocating movement along the coil of a lead having wire guides, characterized in that the rotation drive of the coil is made in the form of kinematically connected in series with each other an electric motor, an intermediate shaft and a spindle shaft carrying a faceplate for the coil, while a block of gears interacting with a freely mounted on the hollow is rigidly fixed to the spindle shaft m of the worm shaft with reciprocal gears, and on the shaft in which the sliding key for the gears is located, a worm is fixed, interacting with a worm wheel mounted on a common shaft with a cam acting on the fingers of the rod provided with guides for the wire.

Description

Wire spooling device

The utility model relates to technological equipment for preparing a welding wire for use in automatic welding machines and semiautomatic devices for electric arc welding.

Known devices for laying wire on a reel, comprising a rotational drive of the coil and a mechanism for reciprocating movement along the reel of the leash, having guides for the wire (see: 1. ed. Certificate. USSR No. 316494, B21C47 / 10, 05.02.70; 2 Auth. Certificate of the USSR No. 1447471, B21C47 / 10, 12.30.88).

A disadvantage of the known devices is the low reliability.

The task is to increase reliability in work.

This object is achieved by the fact that in the device for laying wire on a coil containing located in the housing drive rotation of the coil and the mechanism of reciprocating movement along the coil of the lead, having guides for the wire, the drive

rotation of the coil is made in the form of kinematically sequential

interconnected by an electric motor, an intermediate shaft and a spindle shaft carrying a faceplate for the coil, while the gear block is rigidly fixed to the spindle shaft, interacting with the counter gears freely mounted on the worm shaft, and fixed to the shaft in which the sliding pin for gears is located a worm interacting with a worm wheel.

mounted on a common shaft with a cam acting on the fingers of the rod provided with guides for the wire.

The proposed device is characterized by the presence of the following significant distinguishing features:

a) the rotation drive of the coil is made in the form of a kinematically sequentially interconnected electric motor, an intermediate shaft and a spindle shaft carrying a faceplate for the coil;

b) a block of gears is rigidly fixed on the spindle shaft;

c) the gear block interacts with the reciprocal gears freely mounted on the hollow worm shaft;

d) a sliding key for gears is located in the hollow shaft;

e) a worm is fixed on a hollow shaft;

e) the worm interacts with the worm wheel;

g) the worm wheel is mounted on a common shaft with a cam;

h) the cam interacts with the fingers of the stem;

i) the rod is equipped with guides for the wire.

Studies on patent and scientific and technical literature have revealed a number of technical solutions for a similar purpose, but there are no signs in them. Therefore, the claimed device meets the eligibility conditions of utility models, and tests with further use in the production environment have shown its operability.

The essence of the claimed are illustrated by drawings, where in: FIG. 1 shows a General view of the device for laying wire on a spool, in section; FIG. 2 is a section along AA in FIG. 1; FIG. 3 is a section along BB in FIG. 1; FIG. 4 is a section along BB in FIG. 1; FIG. 5 is a view along arrow D in FIG. 4.

A device for laying wire on a spool includes a housing 1, inside which an input shaft 2 is located, connected by a V-belt drive 3 with an electric motor (not shown in the devil). The shaft 2 by means of gears 4 and 5 is connected to the spindle 6, carrying the faceplate 7 for the coil (to hell, not shown). On the spindle 6, the gear block 9.10 and 11 are rigidly fixed with the help of the key 8, and the gear 5 is fastened with the help of the same key 8. The gears interact with the reciprocal gears 12, 13 and 14, respectively, mounted freely on the hollow worm shaft 15, in which the sliding key 16 for the gears is located. A worm 17 is fixed on the shaft 15, which interacts with the worm wheel 18, mounted on a shaft 20 common to the cam 19. The cam 19 interacts with the fingers 21 of the rod 22, which moves in the guides 23 and carries the guides 24 for the wire (not shown). To control the position of the sliding key 16 in the hollow shaft 15, a plunger 25 is installed, moving inside the shaft 15 in the longitudinal direction of the helm 26 using kinematic transmission 27. The helm 26 is equipped with a pointer 28.

- when the electric motor is turned on, the shaft 2 starts to rotate and through the gears 4 and 5 transmits torque to the spindle 6 with the faceplate 7 on which the wire coil is mounted. At the same time, gears rotate together with the spindle, resulting in the rotation of gears 12n-14, respectively. At a certain position of the sliding key 16, which is set by the helm 26 with the pointer 28, by moving the plunger 25, one of the gears, for example 14, transmits torque to the hollow shaft 15, which rotates the shaft 20 together with the cam 19 through the worm gear 17 -18 the latter, in turn, acts on the fingers 21 and moves the rod 22 with the guides 24 for the wire 24 along the coil in one direction or another, carrying out the process of winding the wire on the coil. To change the step of winding the wire with the helm 26 set the necessary parameters, tracking them according to the pointer 28.

Using the proposed device has shown high reliability, high-quality laying and tension of the wire on the reel.
