[0029] When the ferronickel alloy pipes are fixed in the fixing ring 8, the two groups of moving plates 6 drive the two groups of ferronickel alloy pipes to approach each other by rotating the rotating knob 5, so that the pipe openings are aligned, and the ferronickel alloy pipes are extruded by the extrusion force to move the fixing ring 8 in the rotating ring 7 by continuously rotating the rotating knob 5. Through the cooperation of the L-shaped extrusion block 123, the transmission rod 122, the inclined block 124, the fixing block 127 and the protective plate 128, the protective plate 128 can be rotated upward, and the protective plate 128 is provided with two groups, and the two groups of protective plates 128 are symmetrically arranged with the center line in the vertical direction of the welding table 1 as the axis of symmetry, so that the protective plate 128 can protect the front and back of the welding position of the welding machine, prevent sparks from splashing during welding, and bring safety risks to the workers.

[0030] When the two groups of ferronickel alloy pipes are pressed together, the compression spring 121 will be compressed, and the compression spring 121 will give the ferronickel alloy pipes a counterforce, so that the two groups of ferronickel alloy pipes are tightly pressed together, so that the welding quality is better, and the two groups of ferronickel alloy pipes are prevented from being welded without being tightly pressed together, which may cause a gap in the welding position during welding, affecting the sealing of the two groups of ferronickel alloy pipes.

[0031] When the two groups of nickel-iron alloy pipes need to be welded, first insert the two groups of nickel-iron alloy pipes into the fixing ring 8, start the electric telescopic rod 9, drive the output end of the electric telescopic rod 9 to make the two groups of pressing plates 10 in the fixing ring 8 close to each other, and make the two groups of pressing plates 10 tightly adhere to the outer wall of the nickel-iron alloy pipe to fix the nickel-iron alloy pipe in the fixing ring 8. When the two groups of nickel-iron alloy pipes are fixed, the rotating knob 5 can be turned clockwise to make the bidirectional threaded rod 4 rotate clockwise, so that the two groups of moving plates 6 can move close to each other, and the moving plates 6 drive the fixing ring 8 and the nickel-iron alloy pipe to move close to each other. When the two groups of nickel-iron alloy pipes are close to each other and contact at the welding position, continue to turn the rotating knob 5 clockwise, which will extrude the alignment position of the two groups of nickel-iron alloy pipes. The extrusion force will drive the fixing ring 8 to move close to the moving plate 6 in the rotating ring 7, so that the extrusion spring 121 is compressed. When the extrusion spring 121 is compressed, the extrusion spring 121 will generate a counterforce to the fixing ring 8, so that the welding position between the two groups of nickel-iron alloy pipes is extruded, and the welding position of the two groups of nickel-iron alloy pipes is tightly pressed. When the fixing ring 8 moves close to the moving plate 6, the fixing ring 8 extrudes the L-shaped extrusion block 123, which drives the transmission rod 122 to move, so that the stop block 125 drives the connecting spring 126 to stretch. When the L-shaped extrusion block 123 moves, it will extrude the inclined surface of the inclined block 124, so that the inclined block 124 is extruded and moves downward, driving the transmission spring 1210 to compress. When the inclined block 124 moves downward, it will extrude the top of the bidirectional threaded rod 4 of the protection plate 128, so that the protection plate 128 rotates upward, and the protection plate 128 rotates to a state perpendicular to the welding table 1, so that the two groups of protection plates 128 shield the front and back of the welding position. When the protection plate 128 rotates at the fixed block 127, the torsional spring 129 will be contracted and deformed;

[0032] When it is necessary to release the fixing of the ferronickel alloy pipe, the electric telescopic rod 9 is started to drive the two groups of pressing plates 10 in the fixing ring 8 to move away from each other, so that the ferronickel alloy pipe can be released from the pressing and fixing, when the pressing and limiting of the ferronickel alloy pipe is released, the fixing ring 8 is no longer subjected to the extrusion force, so that the extrusion spring 121 drives the fixing ring 8 to move away from the moving plate 6 and return to the original position, and the fixing ring 8 does not extrude the L-shaped extrusion block 123, and because the connecting spring 126 is in a stretched state, the connecting spring 126 can drive the transmission rod 122 and the L-shaped extrusion block 123 to reset, so that the L-shaped extrusion block 123 does not extrude the inclined block 124, because the transmission spring 1210 is in a compressed state, the transmission spring 1210 can drive the inclined block 124 to move upward and not extrude the protective plate 128, because the torsional spring 129 is in a contracted and deformed state, so that the torsional spring 129 drives the protective plate 128 to return to the original position and be folded, so that the protective plate 128 and the welding table 1 are in a horizontal state, thereby facilitating the feeding and discharging operations.

[0033] Please refer to Figures 1-8 On the basis of the above-mentioned embodiment, in another embodiment of the present application, the auxiliary assembly for polishing the welded portion provided on the shielding assembly further comprises a shielding assembly, and the auxiliary assembly comprises a fixing sleeve 131, a sleeve rod 132, a pressing spring 133, a polishing block 134, a moving frame 135, a pressure sensor 136 and a reset spring 137; the fixing sleeve 131 is fixed to the inner side of the protective plate 128, the sleeve rod 132 is slidably installed on the inner wall of the fixing sleeve 131, the pressing spring 133 is fixed to the bottom of the sleeve rod 132, the bottom of the pressing spring 133 is fixed to the inner wall of the fixing sleeve 131, the top of the sleeve rod 132 is slidably connected with the bottom of the polishing block 134, the moving frame 135 is fixed to the outer surface of the sleeve rod 132, the reset spring 137 is fixed to the side wall of the polishing block 134, the side of the reset spring 137 away from the polishing block 134 is fixed to the inner side of the moving frame 135, and the pressure sensor 136 is fixed to the inner side of the moving frame 135 and electrically connected with the driving motor.

[0034] By arranging the polishing block 134, when the protective plate 128 is rotated to be perpendicular to the welding table 1, the polishing block 134 is pressed against the welded portion of the ferronickel alloy pipe through the cooperation of the pressing spring 133, and the ferronickel alloy pipe is rotated to abut against the polishing block 134 by starting the driving motor, so that the polishing block 134 can polish the burrs and impurities on the welded portion of the ferronickel alloy pipe, the welded portion of the ferronickel alloy pipe is kept in a flat state, and the quality of the welded product is higher.

[0035] When the nickel-iron alloy pipe welding place attached larger burrs and impurities, the larger burrs and impurities on the nickel-iron alloy pipe will rotate to contact the plane of the polishing block 134, and when polishing the smaller burrs, the smaller burrs will generally resist the arc surface of the polishing block 134, and because the elastic coefficient of the return spring 137 is five times that of the spring spring 133, the smaller burrs will directly move against the polishing block 134 and the sleeve rod 132 into the fixed sleeve 131, until the smaller burrs and impurities are polished smooth, when the larger burrs and impurities contact the plane of the polishing block 134, the polishing block 134 will move against the plane of the polishing block 134, so that the polishing block 134 can impact the pressure sensor 136. When the pressure sensor 136 is extruded, an electrical signal is transmitted to the driving motor, and the driving motor stops working when receiving the signal, so that the nickel-iron alloy pipe stops rotating, and the staff can repair the defective product. Preventing the welding of the nickel-iron alloy pipe with larger burrs and impurities from being welded, which will lead to a decrease in the quality of the welded product and affect the sealing of the two groups of nickel-iron alloy pipes.

[0036] The shielding assembly comprises a push block 141, a transmission block 142, a transmission plate 145, an inclined block 143, a return spring 144, a limiting rod 149, a fixed plate 148, a limiting hole 1410, a shielding plate 146 and a pushing spring 147. The push block 141 is fixed at the bottom of the polishing block 134. The inner side of the protective plate 128 is slidably connected with the transmission block 142. The side wall of the transmission block 142 is fixed with the inclined block 143. The inner side of the protective plate 128 is slidably connected with the transmission plate 145. The side wall of the transmission plate 145 is fixed with the return spring 144. The side of the return spring 144 away from the transmission plate 145 is fixed to the inner side of the protective plate 128. The side wall of the transmission plate 145 is fixed with the limiting rod 149. The shielding plate 146 penetrates through the protective plate 128 and is slidably connected. The top of the protective plate 128 is fixed with the pushing spring 147. The side of the pushing spring 147 away from the protective plate 128 is fixed to the top of the protruding part of the shielding plate 146. The side of the shielding plate 146 close to the double-way threaded rod 4 is fixed with the fixed plate 148. The fixed plate 148 is provided with the limiting hole 1410. The inner wall of the limiting hole 1410 is in contact with the outer wall of the limiting rod 149.

[0037] The shielding plate 146 is provided with two groups, which are symmetrically arranged about the center line in the vertical direction of the welding table 1, so that the shielding plate 146 can shield the top of the nickel-iron alloy pipe welding place, thereby preventing the excessive burrs and impurities from being extruded onto the plane of the polishing block 134, which may cause the burrs and impurities to separate from the nickel-iron alloy pipe, and the excessive burrs and impurities to splash upward and hit the staff, which is a safety risk.

[0038] When the protective plate 128 rotates to be perpendicular to the welding table 1, the grinding block 134 abuts against the welded portion of the ferronickel pipe, and when the driving motor is started, the driving pulley rotates to drive the driven pulley to rotate, so that the rotating ring 7 drives the fixed ring 8 and the ferronickel pipe to rotate, and the welded portion of the ferronickel pipe rotates against the grinding block 134, so that the grinding block 134 can polish the burrs and impurities on the welded portion of the ferronickel pipe, and the welded portion of the ferronickel pipe is kept in a flat state, which facilitates the welding operation of the welding machine and improves the product quality. When the welded portion of the ferronickel pipe has large burrs and impurities, the large burrs and impurities abut against the plane of the grinding block 134, so that the grinding block 134 is extruded, and the grinding block 134 moves on the sleeve rod 132. When the grinding block 134 extrudes the pressure sensor 136, the pressure sensor 136 senses the pressure and transmits an electric signal to the driving motor, so that the driving motor stops driving and no longer polishes the welded portion of the ferronickel pipe, so that the staff can process the defective ferronickel pipe. When the grinding block 134 is extruded on the sleeve rod 132 and moves, the push block 141 on the grinding block 134 moves. When the push block 141 moves to contact the transmission block 142, the push block 141 pushes the transmission block 142 away from the fixed sleeve 131, the transmission block 142 drives the inclined block 143 to move, the inclined block 143 extrudes the inclined surface of the transmission plate 145, so that the transmission plate 145 is extruded away from the fixed sleeve 131, the return spring 144 is compressed, the transmission plate 145 drives the limiting rod 149 to move out of the limiting hole 1410, so that the limiting of the fixed plate 148 is released. Since the pushing spring 147 is in a compressed state, the pushing spring 147 drives the shielding plate 146 to move out of the protective plate 128, so that the shielding plate 146 can shield and protect the top of the welded portion of the ferronickel pipe. When the protective plate 128 does not perform the shielding operation, the protective plate 128 drives the grinding block 134 to reset. When the shielding plate 146 needs to be reset, the two groups of transmission plates 145 on the protective plate 128 are pulled away from each other, the shielding plate 146 is moved to the bottom of the protective plate 128, the pushing spring 147 is compressed, and when the shielding plate 146 drives the fixed plate 148 to abut against the protective plate 128, the transmission plate 145 is released because the return spring 144 is in a compressed state, so that the transmission plate 145 drives the limiting rod 149 to extend into the limiting hole 1410 to limit the shielding plate 146.
