Description

Technical Field

[0001] The invention relates to the technical field of argon arc welding machines, in particular to a multifunctional argon arc welding machine. Background Art

[0002] A welding machine is an electrical appliance that provides power with certain characteristics for welding. Welding is flexible, simple, convenient, strong and reliable, and even has the same strength as the parent material after welding. It is widely used in various industrial fields.

[0003] Argon arc welding machine is a machine that uses argon arc welding. It adopts the arc starting method of high-voltage breakdown. An inert gas (usually argon) that does not chemically react with metals flows around the welding arc to form a protective gas hood, so that the tungsten extreme tip, arc and molten pool and metal that is already at high temperature do not come into contact with the air, which can prevent oxidation and absorption of harmful gases. In actual welding work, it is often necessary to weld a batch of identical workpieces. The work difficulty is low and the repetition rate is high. However, due to the nature of welding work, manual welding is still required, especially for some workpieces with special shapes. For example, welding two identical steel rings is often encountered in automobile parts, and automobile production is mass-produced, so a large amount of manpower is required for welding. The cost is very high, but the output is not high. At the same time, during welding work, there will be a lot of welding slag on the workbench.

Gas enters the second piston tube 31 from the air intake pipe 310. When the second rubber piston 38 slides toward the bottom end of the second piston tube 31, it is the air outlet stage. At this time, the first rubber ball 3121 in the one-way air guide structure 312 in the air intake pipe 310 is close to the first blocking block 3122, and the one-way air guide in the air outlet pipe 311 is close to the first blocking block 3122. The first rubber ball 3121 in the gas structure 312 moves away from the first blocking block 3122, and the gas enters the gas collecting tank 41 from the gas outlet pipe 311. After the gas is continuously filled into the gas collecting tank 41, the pressure of the gas collecting tank 41 becomes larger and larger, and the compressed gas will continuously push the second rubber ball 432 in the jet pipe 42 to the right, and at the same time, the second telescopic spring 433 is continuously stretched. When the second rubber ball 432 slides over the second blocking block 431, the gas instantly passes through the jet pipe 42, and then sprays from the soot blowing head 44 to the turntable 28, blowing away the welding slag generated during welding. After the gas is released, the second telescopic spring 433 contracts, pulling the second rubber ball 432 from the right side of the second blocking block 431 to the left side. At this time, the gas collecting tank 41 can perform the next energy storage soot blowing.

The first piston tube (21) drives the turntable (28) to rotate, and at this time, the position of the welding gun (211) can be adjusted so that the welding gun (211) is aimed at the gap between the two steel rings for welding, because the turntable (28) drives the steel rings to rotate; The user should overlap the two steel rings and then place them on the turntable (28). After the anti-skid pad (2103) in the limiting structure (210) on the turntable (28) is subjected to the pressure of the steel ring, it shrinks into the circular groove (2101) under the action of the deformation spring (2102). The remaining anti-skid pad (2103) will not slide, preventing the steel ring from moving at will. After starting the first motor (13), the rotor of the first motor (13) drives the first turntable (14) to rotate, the first turntable (14) drives the belt (15) to rotate, the belt (15) drives the second turntable (16) to rotate, the second turntable (16) drives the screw rod (17) to rotate, the screw rod (17) rotates in the screw hole (110), and the groove (111) on the carrier (19) is locked. The first piston tube (21) is engaged with the protrusion (18), so the carrier (19) slides downward. When the carrier (19) slides downward, the second motor (214) in the carrier (19) and the push-pull rod (22) and the first piston tube (21) connected thereto will also move downward. The calibration block (26) at the lower end of the first piston tube (21) is inserted into the calibration hole (27). The two are mutually engaged. At the same time, the push-pull rod (22) is subjected to downward pressure to drive the first rubber piston (23) to slide downward. Because the first piston tube (21) is in a sealed state, the first rubber piston (23) generates pressure on the gas below. The gas will have an outward thrust on the telescopic column (253), and the telescopic column (253) slides toward both sides of the first piston tube (21). The rubber pad (255) at the end of (253) stops after contacting the inner wall of the steel ring. At this time, the two stacked steel rings are fixed together.

Because the calibration block (26) and the calibration hole (27) at the lower end of the first piston tube (21) are engaged, the first piston tube (21) drives the turntable (28) to rotate. At this time, the position of the welding gun (211) can be adjusted so that the welding gun (211) is aligned with the gap between the two steel rings for welding. Because the turntable (28) drives the steel ring to rotate, the welding gun (211) only needs to maintain the same position. The steel ring will be continuously welded when it rotates.

At this time, the two steel rings are welded together. When the screw rod (17) rotates, it drives the disc (32) and the first protrusion (33) connected to the disc (32) to rotate. The first protrusion (33) cannot move and can only rotate. Therefore, after the second protrusion (34) is squeezed, it drives the movable rod (35) to move left and right continuously. The movable rod (35) The left and right movements drive the second rubber piston (38) to slide continuously in the second piston tube (31). When the second rubber piston (38) slides toward the top of the second piston tube (31), it is the suction stage. At this time, the first rubber ball (3121) in the one-way air guide structure (312) in the suction pipe (310) is away from the first blocking block (3122), and the first rubber ball (3121) in the one-way air guide structure (312) in the outlet pipe (311) is close to the first blocking block (3122). The gas enters the second piston tube (31) from the suction pipe (310). When the first When the second rubber piston (38) slides toward the bottom end of the second piston tube (31), it is the gas discharge stage.

When the second rubber ball (432) slides over the second blocking block (431), the gas instantly passes through the air jet pipe (42) and then is sprayed from the soot blowing head (44) to the turntable (28), blowing away the welding slag generated during welding. After the gas is released, the second telescopic spring (433) contracts, pulling the second rubber ball (432) from the second blocking block (431) from the right to the left.
