Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a carbon slide plate airway structure welding process. Background Art

[0002] The pantograph slide is a key component for the safe operation of electric locomotives. During the operation of the locomotive, the pantograph slide contacts the contact network and has a high-speed relative motion, during which it is constantly subjected to high-speed impact and frequent vibration of the contact network. In order to ensure the safe operation of the locomotive, the electric locomotive adopts an automatic pantograph lowering system. The basic principle is to set an air duct (usually a copper tube) in the slide, and the air source system supplies compressed air from the pantograph to it. When the slide breaks, the air duct is damaged, and the compressed air leaks from the slide air duct. The fast pantograph lowering valve will remove the air in the pantograph lifting device to achieve rapid pantograph lowering. That is to say, the slide breaks and the air duct is damaged, causing the compressed air to leak, and the automatic pantograph lowering will be realized. The air duct structure of the carbon slide disclosed in patent number CN201320383439.8, the air duct structure of the prior art is as described in the background technology of the above patent.

[0037] Specifically, Figure 1 , Figure 2 as well as Fig.11 As shown, the air nozzle is horizontally placed in the air nozzle receiving block 500, the air duct 10 clamped by the axial clamping and alignment mechanism 200 is placed above the air nozzle at 90 degrees, and the axial clamping and conveying mechanism 300 clamps the air duct 10 at 90 degrees and inserts it into the air nozzle connecting hole; after the axial clamping and conveying mechanism 300 clamps the air duct 10 and before conveying the air duct 10, the tight clamping of the air duct 10 by the axial clamping and alignment mechanism 200 can be released first to avoid the axial clamping and conveying mechanism 300 being unable to convey the air duct 10 due to excessive friction between the axial clamping and alignment mechanism 200 and the air duct 10.

[0038] Preferably, if Figure 1 , Figure 2 , Fig. 9 as well as Fig.10 As shown, the carbon slide airway structure welding clamping device also includes a circumferential clamping alignment mechanism 400, such as Fig.10 As shown, some carbon skateboards in the prior art use a non-linear air duct 10 to solve the problem of installation stability, and a curved section 11 is provided at the end of the air duct 10 for welding the air nozzle; therefore, when the air duct 10 and the air nozzle are welded, it is necessary to align the air duct 10 and the air nozzle circumferentially; the circumferential clamping alignment mechanism 400 includes two circumferential clamping alignment parts, each of which includes a fixedly arranged third telescopic part 410, and the telescopic end of the third telescopic part 410 is fixedly connected to a magnetic suction groove 420, and a circumferential alignment block 430 magnetically attracted thereto is provided in the magnetic suction groove 420, and a circumferential alignment groove 431 corresponding to the curved section 11 is provided on the circumferential alignment block 430, and the third telescopic part 410 drives When the two circumferential alignment blocks 430 approach and collide, the curved section 11 of the air duct 10 is clamped, and the air duct 10 is circumferentially aligned with the gas nozzle in the gas nozzle positioning member; the circumferential clamping and alignment mechanism 400 ensures the circumferential alignment of the air duct 10 and the gas nozzle during welding, thereby improving the welding accuracy; the circumferential clamping and alignment mechanism 400 can replace different circumferential alignment blocks 430 according to the specific specifications of the curved section 11 of the air duct 10, so as to adapt to air ducts 10 of different shapes and sizes, especially air ducts 10 with curved sections 11; the automated circumferential alignment reduces the need for manual adjustment and improves welding efficiency; accurate circumferential alignment helps to reduce welding defects and improve the welding quality of the final product.

[0039] Preferably, if Fig.11 as well as Fig.12As shown, an elastic member 142 and a pressure sensor 141 are also provided on the inner bottom side of the positioning groove 140. The pressure sensor 141 is communicatively connected with the driving member 330 of the axial clamping and conveying mechanism 300. When the axial clamping and conveying mechanism 300 conveys the airway 10 to the air nozzle connecting hole, the air nozzle and the air nozzle receiving block 500 bear the downward force of the airway 10. The pressure sensor 141 can measure the pressure borne by the air nozzle receiving block 500, and judge whether the airway 10 is delivered in place according to the pressure data. After the airway 10 is delivered in place, the driving member 330 is controlled to be closed, and the delivery of the airway 10 is stopped, so as to improve the degree of automation and avoid excessive delivery of the airway 10. Specifically, the first telescopic member 210 and the driving member 330 can be controlled to be closed by a PLC controller in the prior art. More specifically, a button 111 for controlling the first telescopic member 210, the second telescopic member 310, the third telescopic member 410 and the driving member 330 is provided on the base 110 to facilitate operation by the staff.

[0040] Preferably, if Fig.11 , Fig.12 as well as Fig.13 As shown, when the gas nozzle and the air duct 10 are welded, a welding ring 20 is arranged above the gas nozzle connecting hole, and the end of the air duct 10 is passed through the welding ring 20, and then the welding ring 20 is heated. After the welding ring 20 melts and solidifies, the gas nozzle and the end of the air duct 10 can be welded together; two L-shaped limiting frames 520 are inserted on the gas nozzle receiving block 500. After the gas nozzle is placed in the gas nozzle receiving block 500, the two limiting frames 520 are inserted into the gas nozzle receiving block 500, and then the welding ring 20 is placed on the top side of the gas nozzle connecting hole and placed between the two limiting frames 520 to prevent the welding ring 20 from falling off the gas nozzle, so that the air duct 10 can pass through the welding ring 20 during transportation. Of course, there is no need for the staff to hold the welding ring 20.

[0041] Preferably, if Fig.15 As shown, a high-frequency welding machine 600 in the prior art is used for welding, and an induction heating ring 610 on the high-frequency welding machine 600 is placed between the nozzle receiving block 500 and the circumferential clamping alignment mechanism 400.

[0042] The above are only preferred implementations of the present invention.
