Abstract

The utility model relates to an automatic wire delivering device with single electrical machinery double driving, which is composed of a motor, a machine frame, a wire delivering device and a pressure arm mechanism, wherein, the driving gear 16 on a single motor output shaft 15 simultaneously drives two driven gears 18 and 14 with the same teeth number and modules to run in the same direction synchronously, and two wire delivering wheels 17 and 13 which are arranged on the same shaft with two driven gears 18 and 14 synchronously run in the same direction. Rolling bearings 4 and 6 which are adjusted and controlled by a pressure arm are arranged above the two wire delivering wheels 17 and 13. A welding stick passes through between the wire delivering wheels 17 and 13 and the rolling bearings 4 and 6 stably. The utility model can feed the wire stably and automatically, and the wire feeding speed can be adjusted.

Description

Automatic wire delivering device with single electrical machinery double driving

The utility model relate to a kind of with the welding wire adjustable speed, pulsation-free, deliver to the two automatic feeding devices that drive of single motor that welding gun goes automatically.

Domestic and international existing wire-feed motor mainly contains single motor single and drives wire feeder and the moving two regulating arm wire feeders of double-motor 4 wheel driven at present.It is that welding wire is three stress points all the time in wire feed that single motor single drives the wire feeder major defect, thereby friction is little, if intensified pressure, surperficial sensitive for damages concerning solid wire; Concerning hollow or flux-cored wire, easily welding wire is crushed.The moving two regulating arm wire feeders of double-motor 4 wheel driven mainly are that equipment unit is many, particularly will reach synchronous and all have certain degree of difficulty with pressure.

The purpose of this utility model provides the automatic feeding device of an adjustment pressure arm of a kind of improved single motor dual drive wheel.

The purpose of this utility model is achieved in that by a driving gear on single motor output shaft and drives two same numbers of teeth simultaneously, with touching the equidirectional synchronous running of several passive tooth crop rotations, thereby also do equidirectional run-in synchronism with coaxial two wire feed rolls of two ring gears.Above two wire feed rolls, respectively there is one taken turns by the antifriction-bearing box of an adjustment pressure arm control.Welding wire just steadily passes through between wire feed rolls and antifriction-bearing box wheel.Reach adjustable speed, steadily, wire feed automatically.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is according to the two forward sight structural representations that drive the automatic feeding device of the single motor that the utility model proposes.

Describe details and service condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device is made up of motor, frame, wire feeder and pressure arm mechanism.

A driving gear 16 is housed on the motor output shaft 15 that stretches out in the adapter plate 20 of frame, and its axial end tightens up with plain cushion and nut.A driving gear 16 drives each same number of teeth about upside, with the ring gear 18 and 14 of modulus.With left and right sides ring gear 18 and 14 coaxial have about each wire feed rolls 17 and 13.Left and right sides ring gear 18 and 14 and the axis hole of left and right sides wire feed rolls 17 and 13 in cover load onto the oil-containing copper sheathing, and use milled screw, make left and right sides ring gear 18 and 14 and left and right sides wire feed rolls 17 and 13 be positioned respectively on the wire feed wheel shaft of the left and right sides.Be pressed with the left and right sides antifriction-bearing box 4 and 6 that is subjected to a pressure arm regulating control respectively above the left and right sides wire feed rolls 17 and 13 of band V-slot.Its pressure size, scalable handle 11, by compression press spring 10, steel bowl 9 and pressurized handgrip axle 5, pressurization is shouldered bar 2 and 8 and is made the low-angle backward rotation around left and right sides lever locating dowel pin 3 and 7 about making respectively, thus changed left and right sides antifriction-bearing box 4 and 6 and left and right sides ring gear 17 and 13 between pressure.On the both sides panel of the adapter plate 20 of frame left and right sides welding support 19 and 12 are arranged, each applies mechanically the welding wire elastic clamp device that button, spring leaf, screw and nut are formed by one on left and right sides welding support 19 and 12.On left welding support 19, also have seal wire to chew 1.Welding wire chews 1 through seal wire,, chews through middle seal wire along turning to the right through the left wire feed rolls 16 of band V-slot and the pressurized that rolls left between the dynamic bearing 4 again, turns to the right to pressurized edge between the left wire feed rolls 13 of being with V-slot and the right antifriction-bearing box 6, till welding gun.In whole wire feed process, the wire feed rate scalable, wire feed is steady, and carries out automatically.

Claims

A kind of two automatic feeding devices of being made up of motor, frame, wire feeder and pressure arm mechanism that drive of single motor is characterized in that:

A, a driving gear 16 drive each same number of teeth about upside, with the ring gear 18 and 14 of modulus;

B, with left and right sides ring gear 18 and 14 coaxial have about each wire feed rolls 17 and 13;

C, left and right sides ring gear 18 and 14 and the axis hole of left and right sides wire feed rolls 17 and 13 in cover load onto the oil-containing copper sheathing, and use milled screw, make left and right sides ring gear 18 and 14 and left and right sides wire feed rolls 17 and 13 be positioned respectively on the wire feed wheel shaft of the left and right sides;

Be pressed with the left and right sides antifriction-bearing box 4 and 6 of pressurized arm of force regulating control above the left and right sides wire feed rolls 17 and 13 of d, band V-slot respectively, its pressure size, scalable handle 11, by compression press spring 10, steel bowl 9 and pressurized handgrip axle 5, about making respectively the pressurization lever 2 and 8 make the low-angle backward rotation around left and right sides lever locating dowel pin 3 and 7, thereby changed left and right sides antifriction-bearing box 4 and 6 and left and right sides ring gear 18 and 14 between pressure.
