Description

Technical Field

[0001] The invention relates to an all-position automatic welding machine, in particular to a high-temperature protection structure of a motor of a swing mechanism of the all-position automatic welding machine, and belongs to the technical field of welding. Background Art

[0002] Welding operations represent a significant portion of the workload in shipbuilding. However, pipeline welding in the domestic shipbuilding industry is still relatively underdeveloped due to its automation, primarily relying on manual labor by welders. This is labor-intensive, resulting in low production efficiency and inconsistent quality. The all-position automatic welding machine is an automated welding auxiliary device that can replace manual welding. It utilizes a gas-shielded automated welding method and is primarily used in conjunction with a gas metal arc welding machine. The all-position automatic welding machine offers advantages such as stable arc combustion, well-formed welds, fewer joints, and a high filler metal deposition rate. This fully utilizes the advantages of all-position welding, significantly improving welding quality and efficiency.

[0003] See also Figure 1 The working principle diagram of the swing mechanism of the full-position automatic welding machine. Before welding, the swing device is installed next to the weld of the pipe to be welded through the fixing device 3 and tightened. The tungsten electrode 5 is aligned with the middle of the weld, and the power is started to weld. The swing device automatically welds along the full circumference of the weld at 360°; multiple cable fixing brackets 4 are provided on the swing motor housing 1.

[0004] Since the tungsten electrode 5 serving as a heat source is close to the swing component 2, a large amount of heat generated during welding is radiated to the motor in the swing motor housing 1. Therefore, the existing full-position automatic welding machine has the following major problems and defects: the high temperature generated by the motor itself cannot be released well, and the current aluminum swing motor housing 1 is easy to absorb heat and lacks protection against heat radiation, which will quickly transfer the high temperature generated by welding to the motor. The high temperature accumulated during thick-wall multi-pass welding operations is radiated to the motor, which is extremely easy to burn the motor, and the normal service life of the motor cannot be guaranteed.

[0005] Therefore, the present invention provides a technical solution by improving the original motor protection shell. Summary of the Invention

[0006] The purpose of the present invention is to improve the existing motor protection shell and provide a high-temperature protection structure for the motor of the swing mechanism of an all-position automatic welding machine, so as to extend the service life of the motor, reduce the use cost of the all-position automatic welding machine, and improve the welding quality and welding efficiency.

[0007] Based on the above objectives, the technical solutions provided by the present invention are as follows:

[0008] A high temperature protection structure for a motor of a swing mechanism of an all-position automatic welding machine, characterized in that: the high temperature protection structure comprises a swing drive motor, an aluminum heat dissipation plate, a stainless steel heat insulation plate and a high temperature cloth;

[0009] The yaw drive motor is fixed on a base in the swing mechanism, and the output shaft is connected to the swing mechanism. The rotational motion is converted into the reciprocating swinging motion of the swing mechanism through the transmission component. The stainless steel heat insulation plate is arranged between the yaw drive motor and the high-temperature area and close to the side of the yaw drive motor housing, and is used to block the high-temperature area from transferring heat to the yaw drive motor to protect the yaw drive motor from damage caused by overheating. The aluminum heat dissipation plate is arranged on the inner side of the bottom of the stainless steel heat insulation plate and there is a gap between the aluminum heat dissipation plate and the stainless steel heat insulation plate. The aluminum heat dissipation plate is close to the lower part of the yaw drive motor housing and is used to quickly dissipate the heat generated by the yaw drive motor. The high-temperature cloth is adhered to the inner side of the stainless steel heat insulation plate on the side of the yaw drive motor to supplement the function of the stainless steel heat insulation plate and further insulate the yaw drive motor.

[0010] The stainless steel heat insulation plate, the aluminum heat dissipation plate and the high-temperature cloth form triple high-temperature protection for the yaw drive motor.

[0011] Furthermore, the high-temperature protection structure also includes a polytetrafluoroethylene plate, which is installed on the inner plane of the aluminum heat sink and located at the sliding track, bearing seat or joint connection of the swing mechanism, serving as a gasket between sliding parts to reduce the friction resistance of the swing mechanism during movement.

[0012] Furthermore, the polytetrafluoroethylene plate is manufactured according to the size of the aluminum heat sink.

[0013] Furthermore, the transmission component includes a connecting rod, a gear or a cam structure.

[0014] Furthermore, the stainless steel heat insulation plate is rectangular, bent at both ends in the length direction, and provided with screw holes around it for connecting and fastening with the outer side of the swing mechanism.

[0015] Furthermore, the aluminum heat sink is processed according to the width of the stainless steel heat insulation plate, and a fan is provided on the aluminum heat sink to dissipate heat by forced air cooling.

[0016] Furthermore, the high temperature cloth is made of high temperature resistant material and is adhered to the stainless steel heat insulation board using high temperature resistant glue.

[0017] Furthermore, the high-temperature cloth is also wrapped around the housing, cables and other irregular surfaces of the yaw drive motor or areas requiring flexible isolation.

[0018] Compared with the existing swing component device for pipe welding, the high temperature protection structure of the swing mechanism motor of the all-position automatic welding machine described in the present invention has the following advantages:

[0019] 1. Effectively reduces the conduction of welding heat to the motor;

[0020] 2. Effectively extend the service life of the motor;

[0021] 3. The stainless steel housing can dissipate heat quickly, increasing the effective working load of the motor;

[0022] 4. Excellent dustproof and waterproof performance, which provides better protection for the motor.

[0023] In summary, the high temperature protection structure takes into account the requirements of high temperature resistance, heat dissipation, low friction and movement reliability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited thereto.

[0030] The structure of the original swing part of the full-position automatic welding machine is shown in Figure 2 The motor 10 in the swing motor protective shell 9 drives the slider 6 to move back and forth along the sliding guide rail 7 through the screw rod 8 to realize the swing of the swing mechanism. There is a defect that the high temperature protection performance of the motor is poor.

[0031] The invention is mainly used for high temperature protection of a motor of a swing mechanism of an all-position automatic welding machine.

[0032] See also Figure 3The high-temperature protection structure of the motor of the swing mechanism of the full-position automatic welding machine includes: a yaw drive motor 11, a polytetrafluoroethylene plate 12, an aluminum heat sink 13, a stainless steel heat insulation plate 14 and a high-temperature cloth 15; wherein, the yaw drive motor 11 is installed on the plane of the polytetrafluoroethylene plate 12, the polytetrafluoroethylene plate 12 is installed on the aluminum heat sink 13, the aluminum heat sink 13 is installed on the bottom inside the stainless steel heat insulation plate 14, the high-temperature cloth 15 is dipped and glued to the inside of the stainless steel heat insulation plate 14, and finally the stainless steel heat insulation plate 14 is fixed to the outside of the swing mechanism with screws.

[0033] The yaw drive motor 11 is a commercially available product and is screwed into the swing mechanism. It is mounted on a flat surface of a polytetrafluoroethylene sheet 12 and then thermally insulated for a third time. Finally, a stainless steel thermal insulation sheet 14 is screwed to the outside of the swing mechanism. The yaw drive motor 11, serving as the core power source, is fixed to the equipment base or bracket. Its output shaft is directly connected to the swing mechanism via a transmission component, driving the swing mechanism's left and right reciprocating motion through rotation.

[0034] The stainless steel heat insulation plate 14 is made of stainless steel, is rectangular, and is bent on both sides in the length direction. Several screw holes are punched around the stainless steel heat insulation plate 14 for fastening to the main body; the stainless steel heat insulation plate 14 is installed between the yaw drive motor 11 and the high-temperature area, close to the outer shell of the yaw drive motor 11, and is used to prevent the high-temperature area from transferring heat to the yaw drive motor 11 or sensitive components, thereby protecting the yaw drive motor 11 from overheating damage.

[0035] The aluminum heat sink 13 is machined to the width of the stainless steel heat shield 14 and mounted on the bottom inside of it. A gap is created between the stainless steel heat shield 14 and the aluminum heat sink 13 to prevent rapid heat conduction. The aluminum heat sink 13 fits snugly around the housing of the yaw drive motor 11 and is equipped with a fan. Its high thermal conductivity allows for rapid heat dissipation from the motor 11 and other electronic components, dissipating the heat through natural convection or forced air cooling.

[0036] The polytetrafluoroethylene plate 12 is a commercial product, purchased according to the size of the aluminum heat sink 13, and installed on the plane of the aluminum heat sink 13; the polytetrafluoroethylene plate 12 is installed on the sliding track, bearing seat or joint connection of the swing mechanism, sandwiched between metal parts, as a gasket between sliding parts, to reduce the friction resistance during the movement of the swing mechanism.

[0037] The high-temperature cloth 15 is made of a high-temperature resistant material on the market. It is glued to the stainless steel insulation board 14 with high-temperature resistant glue on the inside of the stainless steel insulation board 14. The high-temperature cloth 15 is used to make up for the shortcomings of the rigid insulation board and perform secondary insulation. It is wrapped around the outer periphery of the motor housing, cables, etc. to adapt to irregular surfaces or areas requiring flexible isolation.

[0038] The working principle of the present invention is as follows:

[0039] The swing mechanism converts the rotational motion of the yaw drive motor 11 into the required lateral swing motion. The motor output shaft is directly connected to and drives the load. The swing mechanism includes a connecting rod, gear or cam structure.

[0040] When the yaw drive motor 11 drives the swing mechanism, a stainless steel heat shield 14 and high-temperature cloth 15 block external heat from entering. An aluminum heat sink 13 dissipates heat from the yaw drive motor 11. A polytetrafluoroethylene sheet 12 ensures smooth swing joint movement. A high-temperature protection structure seals the entire swing mechanism to ensure stable swinging motion. This high-temperature protection structure balances high-temperature resistance, heat dissipation, low friction, and reliable movement.
