Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1-4, the spot welding machine with self-tapping wire provided in the present embodiment includes an electrode arm 1 and a welding tube 2; one end of the welding tube 2 is provided with a wire outlet 21, and the other opposite end is provided with a rotatable roller 22; the roller is used for winding welding wires; one end of the electrode arm 1 is hinged on the welding tube 2, and the other opposite end is provided with an electrode cap 11; the electrode cap 11 is used for welding off the welding wire at the wire outlet 21 and welding the welding wire on a welding object; the welding pipe 2 is provided with a wire outlet unit 3; and the wire outlet unit 3 is used for driving the welding wire to slide along the welding pipe and extend out of the wire outlet when the electrode arm rotates anticlockwise.
In the initial state, the welding wire is wound on the drum 22, and one end of the welding wire passes through the welding tube 2 and penetrates out along the wire outlet 21 to abut on a welding object, for example, the welding wire abuts on a framework of a mobile phone transformer. As shown in fig. 1, when the electrode arm 1 is activated, the electrode arm 1 is rotated clockwise, that is, the electrode arm 1 is rotated toward the side close to the wire outlet 21, and the electrode cap 11 is rotated to abut against the wire at the wire outlet 21, the wire is cut, and the wire is welded to the welding object. The electrode arm 1 is rotated counterclockwise, and the wire outlet unit 3 drives the welding wire to slide along the welding pipe and extend out of the wire outlet again to prepare for the next welding. The above actions are repeated, each time when the electrode arm 1 rotates anticlockwise, the wire outlet unit 3 drives the welding wire to extend out of the wire outlet 21, and when the electrode arm 1 rotates clockwise, the electrode cap 11 welds the welding wire to the welding object. The spot welding machine capable of automatically discharging wires provided by the invention is convenient for a worker to operate by one hand.
As a further improvement to the above technical solution, the wire discharging unit 3 includes a conveying roller 31, a force transmission gear 32 and a driving gear 33 which are rotatably mounted on the bracket from bottom to top; the welded pipe 2 is provided with a gap 23; the edge of the notch 23 is provided with a bracket 24 tangent to the peripheral surface of the welded pipe; a circular ring 12 is arranged at one end of the electrode arm 1 far away from the electrode cap; the circular ring 12 is rotationally connected with the bracket 24; the ring 12 extends inwards along the radial direction to form a shifting tooth 121; one side of the driving gear 33 close to the bracket 24 extends into the circular ring to form a ratchet 331; each tooth groove of the ratchet wheel 331 is internally provided with a thrust tooth 332; one end of the thrust tooth 332 is rotatably connected with the driving gear, and the other end of the thrust tooth abuts against the inner side wall of the circular ring; gear teeth are machined on the outer peripheral surface of one side, close to the bracket 24, of the conveying roller 31; the gear teeth, the force transmission gear and the driving gear are meshed in sequence; a welding wire conveying channel is formed between the bottom of the conveying roller 31 and the inner side wall of the welding tube 2.
In the initial state, the welding wire passes through the welding wire feeding channel, and the feeding roller 31 is pressed against the surface of the welding wire. When the electrode arm 1 rotates counterclockwise as shown in fig. 2, the poking teeth 121 push the ratchet wheel 331 to rotate counterclockwise through the thrust teeth 332, so that the driving gear 33 rotates counterclockwise; the driving gear 33 drives the conveying roller 31 to rotate anticlockwise through the transmission of the force transmission gear 32 and gear teeth on the conveying roller 31, so that the welding wire slides in the welding wire conveying channel and extends out along the wire outlet. When the electrode arm 1 rotates clockwise, the poke tooth 121 is separated from the thrust tooth 332. When the set tooth 121 abuts against the thrust tooth 332 located in the next tooth slot during the clockwise rotation, the set tooth 121 pushes the thrust tooth 332 to rotate clockwise, the thrust tooth 332 is accommodated in the tooth slot of the ratchet 331, the set tooth 121 is separated from the thrust tooth 332, no force acts on the drive gear 33 during this process, and the drive gear 33 does not rotate. That is, when the electrode arm 1 rotates clockwise, the feed roller 31 does not rotate. The conveying roller 31 is convenient to control to rotate only when the electrode arm 1 rotates anticlockwise, and the welding wire is convenient to control to slide towards the wire outlet only when the electrode arm 1 rotates anticlockwise.
As a further improvement to the above technical solution, the thrust teeth are rotationally connected with the driving gear through a first torsion spring; the first torsion spring is used for enabling the thrust teeth to cling to one inner side wall of the tooth groove of the ratchet wheel in a counterclockwise rotating mode. In an initial state, the thrust teeth cling to one inner side wall of the tooth grooves of the ratchet wheel. When the shifting teeth 121 are separated from the thrust teeth 332, the thrust teeth 332 are tightly attached to one inner side wall of the tooth groove of the ratchet wheel in a counterclockwise rotation mode under the action of the first torsion spring. Facilitating the thrust teeth 332 to return to the initial state.
As a further improvement to the above technical solution, the ring is rotatably connected with the bracket through a second torsion spring; the second torsion spring is used for keeping the electrode arm to rotate along the counterclockwise direction. In an initial state, an included angle is formed between the electrode arm and the welded pipe, and the electrode cap 11 is far away from the wire outlet. When welding is needed, the electrode arm is pressed by a finger and rotates clockwise to complete welding. And after welding is finished, loosening the electrode arm, and enabling the electrode arm to rotate anticlockwise to recover the initial state under the action of the second torsion spring. Is convenient for workers to operate by one hand.
As a further improvement to the technical scheme, a plurality of hobbing teeth are arranged on the outer peripheral surface of the conveying roller. The welding wire is convenient to convey.
As a further improvement to the above technical solution, a rotatable adjusting needle 241 is mounted on the outer side surface of the bracket 24; an L-shaped positioning rod 13 is arranged on one side of the electrode arm 1 close to the circular ring; one end of the positioning rod 13 is fixed on the peripheral surface of the electrode arm, and the other opposite end extends to the outer side surface of the bracket to be abutted against the adjusting needle. Since the length of the welding wire extending out of the wire outlet is equal to the arc length swept by the conveying roller 31 when it rotates counterclockwise. That is, the length of the wire extending out of the wire outlet is determined by the angle of counterclockwise rotation of ratchet 331. Similarly, the length of the welding wire extending out of the wire outlet depends on the anticlockwise rotation angle of the electrode arm. As shown in fig. 4, the electrode arm 1 rotates counterclockwise, and stops rotating when the positioning rod 13 abuts against the adjustment needle 241. That is to say, the adjusting needle 241 is rotated to adjust the included angle between the electrode arm and the welding tube, so as to adjust the length of the welding wire extending out of the wire outlet.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
