Description

Technical Field

[0001] The utility model relates to the field of resistance welding, in particular to a welding component and a resistance welding machine thereof. Background Art

[0002] Existing resistance welding machines generally include an upper electrode and a lower electrode that can approach or separate from each other. The workpiece is placed between the upper electrode and the lower electrode. During welding, both the upper electrode and the lower electrode are in contact with the workpiece, so that a welding circuit can be formed when energized to perform welding operations on the workpiece. Currently, both the upper electrode and the lower electrode are connected to the welding machine main body through brass electrode tiles, and then electrically connected to the power supply device through copper strips or copper buses via the brass electrode tiles. Since slot holes need to be opened on the electrode tiles to realize the installation of the electrodes, this increases the consumption of copper material for the electrode tiles, resulting in a higher equipment cost. Moreover, the surface of the electrode tiles is prone to corrosion and its service life is reduced, which cannot meet the market demand. Summary of the Utility Model

[0003] Based on this, the purpose of the present utility model is to provide a welding component and a resistance welding machine thereof, which have the advantages of low cost, low energy consumption, and long service life.

[0004] A welding component includes:

[0005] A first electrode module, including a first electrode, a first conductive plate, and a first mounting seat. The first electrode is mounted on the first mounting seat through the first conductive plate, and the first electrode is electrically connected to the first conductive plate;

[0006] A second electrode module, including a second electrode, a second conductive plate, and a second mounting seat. The second electrode is mounted on the second mounting seat through the second conductive plate. The second electrode is electrically connected to a power supply through the second conductive plate and is spaced corresponding to the first electrode;

[0007] A conductive belt, one end of which is electrically connected to the first conductive plate and the other end is communicated with a power supply.

[0008] For the welding component of the present utility model, by splitting the structure of the traditional electrode tile, the material consumption of the conductive structure is reduced, thus greatly reducing the processing cost.

[0009] Further, the first conductive plate and the second conductive plate are made of red copper. This structure can improve the conductivity, reduce the resistance value, thereby reducing energy loss. At the same time, it reduces the corrosion degree of the surface of the conductive plate and extends the service life.

[0010] Further, the first mounting seat and the second mounting seat are made of steel. This structure can improve the connection reliability and durability of the mounting seat.

[0011] Further, a first T-shaped groove is formed in the first mounting seat. The opening of the first T-shaped groove faces the first conductive plate and corresponds to the mounting hole formed in the first conductive plate. A second T-shaped groove is formed in the second mounting seat. The opening of the second T-shaped groove faces the second conductive plate and corresponds to the mounting hole formed in the second conductive plate. This structure facilitates installation, disassembly, and replacement, with a simple structure and convenient operation.

[0012] Further, the first electrode and the second electrode are located on the same vertical axis. This structure improves the welding quality.

[0013] The present utility model also discloses a resistance welding machine, which includes a frame and the welding assembly as described above. The first mounting seat is arranged on the frame through a driving source, and the driving source makes the first electrode approach or move away from the second electrode. The second mounting seat is fixedly arranged on the frame. This resistance welding machine has the advantages of low cost and long service life, and its welding ability is stronger than that of other products of the same type and the same transformer power.

Detailed Description of the Embodiment

[0019] Please refer to Figure 1 , Figure 1 is the overall view of the resistance welding machine described in the present utility model. The present utility model discloses a resistance welding machine, which includes a frame 1 and a welding assembly.

[0020] The frame 1 includes a receiving portion 11 and a base portion 12. A power supply for providing the current required for welding to the electrodes is accommodated in the receiving portion 11. The base portion 12 is provided on one side of the receiving portion 11. A driving source 3 fixed to the frame 1 is provided above the base portion 12, such that the driving source 3, the receiving portion 11, and the base portion 12 form a "C"-shaped structure. The driving source 3 can be a structure such as a cylinder or a motor. A welding space is formed between the driving end of the driving source 3 and the base portion 12, and a welding assembly is disposed in this welding space.

[0021] The welding assembly includes a first electrode module 21, a second electrode module 22, and a conductive band 23. In this embodiment, the first electrode module 21 is fixed to the driving end of the driving source 3, such that the first electrode module 21 can approach or move away from the second electrode module 22 under the drive of the driving source 3. The second electrode module 22 is fixedly provided on the base portion 12 and is electrically connected to the power supply. The conductive band 23 electrically connects the first electrode module 21 to the power supply, thereby forming a welding circuit. The conductive band 23 is usually made of a flexible structure, so that the first electrode module 21 can reciprocate while maintaining electrical connection with the power supply.

[0022] Please refer to Figure 1 and Figure 2 , Figure 1 which is the overall view of the resistance welding machine described in the present utility model; Figure 2 which is the structural diagram of the first electrode module described in the present utility model (the electrode is not shown). The first electrode module 21 includes a first electrode 211, a first conductive plate 212, and a first mounting seat 213. The first electrode 211 is mounted on the bottom of the first mounting seat 213 through the first conductive plate 212. The first conductive plate 212 is made of copper, such that the first electrode 211 is electrically connected to the first conductive plate 212, improving the conductivity and reducing the resistance value.

[0023] A first T-shaped groove 214 is formed on the first mounting seat 213. The opening of the first T-shaped groove 214 faces the first conductive plate 212 and corresponds to the mounting hole 24 formed on the first conductive plate 212. A fastening screw is clamped in the first T-shaped groove 214, and its threaded end passes through the mounting hole 24 and is fastened to the first electrode 211, thereby realizing the installation of the first electrode 211. To improve the durability and reliability of the first mounting seat 213, the first mounting seat 213 is made of steel plate.

[0024] Please refer to Figure 1 and Figure 3 , Figure 1 which is the overall view of the resistance welding machine described in the present utility model; Figure 3This is a structural diagram of the second electrode module of the present utility model (the electrodes are not shown). The second electrode module 22 includes a second electrode 221, a second conductive plate 222, and a second mounting seat 223. The second electrode 221 is mounted on the top of the second mounting seat 223 through the second conductive plate 222. The second conductive plate 222 is made of red copper, so that the second electrode 221 is electrically connected to the second conductive plate 222, improving the conductivity and reducing the resistance value.

[0025] The second electrode 221 corresponds to the first electrode 211 at an interval, and its direction can be selected according to the actual welding direction. In this embodiment, the welding direction is the vertical direction. Therefore, the first electrode 211 and the second electrode 221 are located on the same vertical axis. A second T-shaped groove 224 is formed in the second mounting seat 223. The opening of the second T-shaped groove 224 faces the second conductive plate 222 and corresponds to the mounting hole 24 formed in the second conductive plate 222. The fastening screw is clamped in the second T-shaped groove 224, and its threaded end passes through the mounting hole 24 and is tightly connected to the second electrode 221, thereby realizing the installation of the second electrode 221. To improve the durability and reliability of the second mounting seat 223, the second mounting seat 223 is made of steel plate.

[0026] There is only one set of the conductive belts 23, and the conductive belts 23 are copper belts or copper bars. The second electrode 221 is directly electrically connected to the power supply through the second conductive plate 222.

[0027] Or there are two sets of the conductive belts 23, and the conductive belts 23 are copper belts or copper bars. One ends of the conductive belts 23 connected to the first electrode module 21 and the second electrode module 22 are electrically connected to the first conductive plate 212 and the second conductive plate 222 respectively, so that the first electrode 211 and the second electrode 221 are directly electrically connected to the positive and negative electrodes of the power supply through the first conductive plate 212 and the second conductive plate 222 respectively.

[0028] During use, the workpiece to be welded is placed on the lower electrode, the driving source is started, and the first electrode is pushed to move towards the second electrode until it contacts the workpiece. When both the first and second electrodes contact the workpiece, a welding circuit is formed, thereby realizing resistance welding of the workpiece. After welding is completed, the driving source is started to reset the first electrode to disconnect the welding circuit. Workers or a manipulator can take out the welded workpiece and place the next workpiece to be welded.

[0029] A welding assembly and its resistance welding machine of the present utility model reduce the material usage amount of the conductive structure by splitting the structure of the traditional electrode tile, thereby greatly reducing the processing cost. In addition, this structure can improve the conductivity of the circuit, reduce the resistance value, reduce energy loss, reduce the corrosion degree on the surface of the conductive plate, and extend the service life while improving the connection reliability and durability.
