Description

Technical Field

[0001] The utility model belongs to the technical field of welding, in particular to a puppet welding device. Background Art

[0002] Puppet welding is a special resistance spot welding process, which is used in situations where welding space is insufficient and accessibility of welding clamps is poor. By fixing the puppet welding clamp on the tooling, the welding current is provided by the external welding machine welding clamp through the copper bus and the attached cable, and the puppet welding clamp presses the plate to form a loop to complete the welding. The traditional puppet welding structure is generally an X-shaped structure, with limited space layout on the tooling fixture. When designing the tooling, it is impossible to avoid parts or fixture positioning and support, etc., and the scope of application is limited.

[0003] For example, a puppet welding device disclosed in a Chinese patent document (publication number: CN 216065976 U) includes a fixed connecting plate and a movable connecting plate, wherein the upper part of the fixed connecting plate is fixedly connected to a static electrode assembly, and the upper part of the movable connecting plate is provided with a first L-shaped connecting plate and a second L-shaped connecting plate in sequence from top to bottom, wherein the lower part of the first L-shaped connecting plate is fixedly connected to a support plate, and the end of the support plate is fixedly connected to a sliding guide block, and the upper part of the second L-shaped connecting plate is fixedly connected to a cylinder, and the telescopic rod of the cylinder is threadedly connected to the movable electrode assembly, and the movable electrode assembly is installed in the sliding guide block, and the middle parts of the static electrode assembly and the movable electrode assembly are connected to the attached cable through a connector, and can be widely used in tooling fixtures where some welding points of the body-in-white cannot be welded due to insufficient welding space and poor accessibility of the welding clamp, thereby improving the flexibility of the tooling.

[0004] However, the above scheme still has the following shortcomings when implemented:

[0005] 1. When welding special welding dead angles, since the device is fixed on the ground as a whole, its flexibility is poor and it is impossible to complete the rotating welding process in a limited space, such as when welding the parts below after completing the welding on the upper part of the parts;

[0006] 2. A large amount of harmful gases will be generated during welding. If they are not adsorbed and filtered, a large amount of harmful gases will be stored in the workshop, which will affect the health of the workers.

[0007] Therefore, we propose a puppet welding device. Utility Model Content

At the same time, the gas adsorption mechanism 3 is provided, and the harmful gas attempted during welding can be adsorbed and filtered and then discharged, thereby avoiding damage to the workers' bodies.

[0026] like Figures 1 to 5As shown, the mounting ring mechanism 2 includes a ring body bracket 21 and an arc-shaped slider 22. A circular slide groove 23 is opened inside the ring body bracket 21. Three arc-shaped sliders 22 are slidably connected inside the circular slide groove 23. The three arc-shaped sliders 22 are fixedly connected to the device main body shell 1. The three arc-shaped sliders 22 can slide inside the circular slide groove 23. After the device main body shell 1 and the three arc-shaped sliders 22 are fixed to each other, it is only necessary to rotate the device shell body to drive the three arc-shaped sliders 22 to rotate in the circular slide groove 23, thereby completing the rotation of the device main body shell 1. The rotation process has little resistance and is more convenient to use.

[0027] A welding assembly 4 is also provided inside the main body shell 1 of the device and near the front. Two welding rods 5 are provided at the output end of the welding assembly 4. The welding rods 5 are electrically connected to the welding assembly 4. The welding assembly 4 includes components of the welding equipment, which are assembled inside the welding assembly 4, and the welding rods 5 are connected to the welding assembly 4, so that the welding assembly 4 can weld the components through the welding rods 5.

[0028] The gas adsorption mechanism 3 includes a filter element group 31, an air pump 32, an air inlet pipe 33, an adsorption chamber 34, a filter screen 35 and an air outlet pipe 36. The filter element group 31 is provided on one side of the air pump 32, and an air inlet pipe 33 is provided on the front of the air pump 32. An adsorption chamber 34 is provided at the connection of the air inlet pipe 33, and two filter screens 35 are provided on one side wall of the adsorption chamber 34. An air outlet pipe 36 is also provided on one side of the filter element group 31. One end of the air outlet pipe 36 is connected with the filter element group 31, and the other end passes through the device main body shell 1 and is connected with the outside world. The air inlet pipe 33 passes through the welding assembly 4 and the device main body shell 1 and is connected with the outside world, and is used in conjunction with the welding rod 5. The welding rod 5 will generate more exhaust gas during welding, and the exhaust gas will be transported to the filter element group 31 through the adsorption chamber 34 and the air inlet pipe 33 under the action of the air pump 32, and after being filtered by the filter element group 31, the gas is discharged to the outside through the air outlet pipe 36.

[0029] A handle 6 is also fixedly connected to the top of the mounting ring mechanism 2, and a connecting wire 7 is also provided on the back side of the device main body shell 1.

[0030] The working principle and use process of the utility model are as follows: when in use, the device is first removed from the bracket. During the removal process, the device can be taken and pulled by the handle 6. When the taking is completed, the device is started, and the welding rod 5 is placed at the welding position, and the power is output to it through the welding assembly 4, so as to complete the welding work.

After welding is completed at one point in the same area, if welding is required at the opposite point, the purpose of rotating the device main body shell 1 can be achieved by rotating the auxiliary rotating rod 8. The three arc-shaped sliders 22 can slide in the circular slide groove 23. After the device main body shell 1 and the three arc-shaped sliders 22 are fixed to each other, the three arc-shaped sliders 22 can be driven to rotate in the circular slide groove 23 by rotating the device main body shell 1, thereby completing the rotation of the device main body shell 1. The resistance during the rotation is small, and the use is more convenient.
