Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding machines, in particular to an automatic spot welding machine. Background Art

[0002] Welding machine is a common welding equipment. It can be equipped with arc welding robot data connection port and wire feeding mechanism to realize automatic welding. The welding functions include carbon dioxide shielded welding, DC welding and argon arc timed spot welding, etc. It is suitable for welding various metals such as aluminum, aluminum-magnesium alloy, stainless steel, carbon steel, copper, etc.

[0003] Wire feeding mechanisms are commonly found in automated welding machines for disc-type welding wires. Most of them use wire reels to carry wound welding wire or film materials. These wound welding wires are in large quantities at a time and can be supplied relatively continuously for welding of special batch metal parts. In the wire feeding mechanism, the wire reel is mounted on a rotatable threaded column of the welding machine. After the wire reel is clamped firmly by the nut and the threaded column, the wire feeder of the welding machine is used to clamp and drive the wire reel to rotate so that the welding wire or film material is continuously fed.

[0004] However, when the above-mentioned automated welding machine for disc-type welding wire needs to replace the used wire reel and reinstall a new wire reel, the operator needs to rotate the operating nut multiple times in a rather cumbersome manner to replace it, which is time-consuming and inconvenient.

[0005] Based on this, the utility model designs an automatic spot welding machine to solve the above problems. Summary of the invention

[0012] Preferably, a wire feeder is arranged in the accommodating bin of the machine body, and a door panel is arranged at the opening of the accommodating bin of the machine body.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the limiting rod that can slide through the limiting mechanism assists the quick disassembly and assembly of the wire reel auxiliary tube, and the rounded end thereof can be directly pushed and retracted into the installation column when the wire reel auxiliary tube is connected to the installation column without affecting the installation of the wire reel auxiliary tube;

[0014] Pushed by the spring of the limiting mechanism, after the wire reel auxiliary tube is installed, the vertical surface of the rounded end of the limiting rod is used to cooperate with the abutment plate to clamp the wire reel auxiliary tube to prevent it from falling out.

[0027] The machine body 1 installs the functional components of automatic wire feeding in the placement bin 2 to increase the automation capability. The wire reel 12 required for automatic wire feeding is placed on the outer wall of the mounting column 5 through the auxiliary tube 13 for use. When the wire reel 12 and the auxiliary tube 13 are disassembled and assembled, the limiting rod 9 which can slide through the limiting mechanism is used for quick disassembly and assembly. The limiting rod 9 can be pushed and retracted into the mounting column 5 by its rounded end when the auxiliary tube 13 is connected to the mounting column 5 without affecting the installation of the auxiliary tube 13 of the wire reel 12. After installation, the vertical surface of its rounded end is used to cooperate with the abutment plate 4 to clamp the auxiliary tube 13 of the wire reel 12. When the auxiliary tube 13 of the wire reel 12 is removed, it can be retracted into the mounting column 5 after simple control to quickly remove the auxiliary tube 13 of the wire reel 12.

[0028] Preferably, the limiting mechanism further includes a placement groove 7, a dial plate 8 and a spring 10, the placement groove 7 is opened at one end of the mounting column 5, and one end of the dial plate 8 is slidably connected in the placement groove 7;

[0029] The limiting mechanism is used to install the dial plate 8 and the limiting rod 9 through its placement groove 7 to assist the operation of the limiting rod 9.

[0030] Preferably, one end of the limiting rod 9 extends to the placement groove 7 and is fixedly connected to one end of the shift plate 8, and a spring 10 is fixedly connected between one end of the shift plate 8 and the inner wall of the placement groove 7;

[0031] The spring 10 in the limiting mechanism is placed in the groove 7 to provide a rebound thrust for the shift plate 8 and the limiting rod 9, so that the rounded end of the limiting rod extends out of the mounting column 5, limiting the movement of the auxiliary tube 13 of the wire reel 12 to prevent it from falling out. The shift plate 8 is used to facilitate personnel to control the rounded end of the limiting rod to retract into the mounting column 5, so that the auxiliary tube 13 of the wire reel 12 can be removed more quickly.

[0032] Preferably, two symmetrical plug rods 6 are fixedly connected to the outer wall of the mounting column 5, and two symmetrical slots 14 are opened on the inner wall of the auxiliary tube 13, and the two plug rods 6 are respectively inserted into the two slots 14;

[0033] The two insertion rods 6 on the outer wall of the mounting column 5 and the two slots 14 of the auxiliary tube 13 are plugged into each other so that when the wire reel 12 is mounted on the mounting column 5, it will not rotate relative to the mounting column 5, and the output welding wire can be replaced.

[0034] Preferably, one end of the dial plate 8 extends out of the placement groove 7 and is fixedly connected to a baffle 11;

[0035] The baffle plate 11 moves with the paddle plate 8 to shield the placement groove 7 to prevent impurities from affecting the spring 10 .

[0036] Preferably, a wire feeder 15 is provided in the placement bin 2 of the machine body 1, and a door panel 16 is provided at the opening of the machine body 1 located at the placement bin 2;

[0037] The welding wire wound on the wire reel 12 is fed by the wire feeder 15 , and the placement bin 2 is closed by the door panel 16 to protect the internal components of the placement bin 2 .

[0038] A specific application of this embodiment is: the wire reel 12 wound with a certain amount of welding wire is placed on the installation column 5 for use. By using a large amount of welding wire, the welding machine can be supplied more continuously, and the same batch of metal parts that need this type of welding wire are specially spot welded. The welding wire wound on the wire reel 12 is introduced into the wire feeder 15 in the placement bin 2, and the wire feeder 15 extracts and outputs it for use. When installing a new wire reel 12, just align the two slots 14 of the auxiliary tube 13 with the two plug rods 6 of the installation column 5, and then push the wire reel 12 toward the stop plate 4;

[0039] When pushing, when one end of the wire reel 12 contacts the limiting rods 9 of the two limiting mechanisms, it will first contact the rounded corner at one end thereof, and as the auxiliary tube 13 of the wire reel 12 is pushed, the rounded end of the limiting rod 9 will be squeezed and moved down, and at this time the auxiliary tube 13 of the wire reel 12 can be completely pushed into place. After the auxiliary tube 13 of the wire reel 12 is in place, the limiting rod 9 will be subjected to the rebound thrust of the spring 10, so that the rounded end of the wire reel 12 moves up and is exposed, and the side of the rounded end facing the auxiliary tube 13 is in a vertical surface shape, and then the wire reel 12 is restricted and stuck between the limiting rod 9 and the abutment plate 4, completing the placement of the wire reel 12;

[0040] When removing the wire reel 12 after using the welding wire, the staff only needs to push the two plates 8 of the limiting mechanism toward each other so that the rounded end of the limiting rod 9 is retracted into the mounting column 5, and the wire reel 12 and the auxiliary tube 13 can be quickly removed.
