The equipment automatically and continuously aligns and welds the fine thermal couple wires of two different conductors, avoiding the problem that the automatic welding pipe threading device is not easy to continuously align and weld the fine thermal couple wires during the welding process, resulting in poor use of the equipment;
[0041] An anti-warping wire assembly is arranged on the right side of the square box 12, and the anti-warping wire assembly includes two bottom concave plates 16, and the two bottom concave plates 16 are fixed on the right side of the square box 12.

[0042] When in use, the operating table 1 supports the double-arc concave plate 2, and the staff puts the U-shaped quartz tube in the double-arc concave plate 2. At the same time, the operating table 1 supports the L-shaped plate 3, the L-shaped plate 3 supports the U-shaped arc frame 4, and the U-shaped arc frame 4 supports the I-shaped plate 5. The staff passes the fine thermal couple wire in the I-shaped plate 5 through the wire-passing port of the L-shaped plate 3, and starts the welding and cutting module 6 on the operating table 1. The telescopic end of the electric telescopic rod 1 in the welding and cutting module 6 moves downward, and the telescopic end of the electric telescopic rod 1 drives the ultrasonic welding head to move downward, and the ultrasonic welding head of the welding and cutting module 6 welds the fine thermal couple wire.

[0043] Since the fine thermal couple wires of two different conductors are difficult to be continuously aligned and welded during the through-tube welding process, at this time, the staff places the fine thermal couple wires of two different conductors into the Y-shaped arc groove of the Y-shaped conductor block 7, the operating table 1 supports the vertical ring 10, and the electric telescopic rod 2 11 in the vertical ring 10 is started, and the telescopic end of the electric telescopic rod 2 11 begins to move to the left, and the telescopic end of the electric telescopic rod 2 11 drives the square box 12 to move to the left, the square box 12 drives the inclined rod 13 to move to the left, the inclined rod 13 drives the sliding shell 14 to move to the left, the sliding shell 14 slides to the left in the through groove of the Y-shaped conductor block 7, and the sliding shell 14 drives the magnetic block 15 to move to the left, and the staff energizes the magnetic block 15, and the magnetic block 15 generates magnetism, and the magnetic block 15 adsorbs the two different The fine thermal couple wire of the conductor moves to the left, and the fine thermal couple wire enters the quartz tube of the double arc concave plate 2.

Under the elastic force of the arc spring strip 84, the fine thermal couple wire adsorbed by the magnetic block 15 slowly contacts in the Y-shaped arc groove of the Y-shaped conductor block 7, so that the two fine thermal couple wires will not contact and dislocate, so as to avoid the contact and dislocation of the fine thermal couple wires in the automatic welding pipe-threading device during the welding process, resulting in poor welding quality of the equipment.

The two wire meshes 94 are located above the Y-shaped conductor block 7. The wire mesh 94 transfers heat to the fine hot spot couple wire during the process of moving to the left, so that the fine hot spot couple wire can be preheated during winter welding, so as to avoid the poor welding effect of the fine hot spot couple wire in a low temperature environment during the welding process of the automatic welding pipe penetration device.
[0048] The preheating device 9 also includes an arc plate 95, a square plate 96 and a chamfer strip 97.

[0049] A method for using an automatic welding pipe threading device for a fine thermal couple wire comprises the following steps:
[0050] S1. The staff puts a U-shaped quartz tube into the double-arc concave plate 2, and passes the fine thermal couple wire in the I-shaped plate 5 through the wire opening of the L-shaped plate 3;
[0051] S2, the magnetic block 15 drives the fine thermal couple wire to move toward the middle, so that the end point of one fine thermal couple wire contacts the wall surface of another fine thermal couple wire;
[0052] S3, when the equipment is threading the pipe, the ultrasonic welding head of the welding and cutting module 6 welds the fine thermal couple wire, and the L-shaped switch of the welding and cutting module 6 cuts the fine thermal couple wires of two different conductors;
[0053] S4, the rubber shaft plate 17 moves against the top of the fine thermal couple wire, and the fine thermal couple wire will not rise in the Y-shaped arc groove;
[0054] S5. Under the elastic force of the arc spring strip 84, the fine thermal couple wire adsorbed by the magnetic block 15 slowly contacts the Y-shaped arc groove of the Y-shaped conductor block 7;
[0055] S6. When the roller 87 rolls to the left, the roller 87 supports the horizontal plate 82 to reduce the severe shaking of the equipment during the pipe welding process;

Under the elastic force of the arc spring strip 84, the fine thermal couple wire adsorbed by the magnetic block 15 slowly contacts in the Y-shaped arc groove of the Y-shaped conductor block 7, so that the two fine thermal couple wires will not contact and dislocate, preventing the fine thermal couple wires of two different conductors from contacting and dislocating when the equipment is in use, thereby avoiding the problem of poor welding quality of the equipment caused by the contact and dislocation of the fine thermal couple wires during the welding process of the automatic welding pipe threading device.
[0059] While the inverted U-shaped plate 81 drives the cross plate 82 to move leftward, the cross plate 82 drives the inverted U-shaped frame 85 to move leftward, and the inverted U-shaped frame 85 drives the roller 87 to move leftward. Under the action of friction, the roller 87 rolls in the concave track 86, so that when the roller 87 rolls to the left, the roller 87 supports the cross plate 82, thereby reducing the violent shaking of the equipment during the pipe welding process, thereby avoiding the problem of poor welding effect caused by the violent shaking of the automatic welding pipe welding device during the welding process.
[0060] While the horizontal plate 82 drives the inverted U-shaped frame 85 to move to the left, the inverted U-shaped frame 85 drives the T-shaped rod 91 to move to the left, the T-shaped rod 91 drives the casing 92 to move to the left, the casing 92 drives the resistance heater 93 to move to the left, the casing 92 drives the wire mesh 94 to move to the left, the resistance heater 93 is started, the resistance heater 93 begins to heat up, and the resistance heater 93 transfers heat to the wire mesh 94, so that the wire mesh 94 transfers heat to the fine hot spot couple wire in the process of moving to the left, so that the fine hot spot couple wire can be preheated during winter welding, preventing the equipment from welding in winter due to low temperature causing poor welding effect of the fine hot spot couple wire, thereby avoiding the problem of poor welding effect of the fine hot spot couple wire in a low temperature environment during the welding process of the automatic welding pipe threading device.
[0061] While the inverted U-shaped frame 85 drives the T-shaped rod 91 to move left, the T-shaped rod 91 drives the arc plate 95 to move left, the arc plate 95 drives the square plate 96 to move left, and the square plate 96 drives the chamfering strip 97 to move left, so that the chamfering strip 97 can scrape off the impurities accumulated in the concave rail 86 during the movement to the left, thereby preventing the impurities from accumulating in the concave rail 86 in the equipment, thereby avoiding the problem of equipment operation jamming due to the accumulation of impurities in the equipment during the welding process of the automatic welding pipe threading device.
