Description

Technical Field

[0001] This utility model relates to the field of sheet metal welding equipment technology, specifically to an automotive body sheet metal welding device. Background Technology

[0002] Sheet metal welding mainly involves applying a strong current to electrodes to generate a resistance heating effect, and then applying pressure to locally melt the contact points of the sheet metal, ultimately forming a strong circular weld point that connects the stacked sheets into one piece. However, in existing sheet metal welding equipment, the contact points between the electrodes and the sheet metal parts are prone to burning and sticking, which hinders continuous welding operations and affects welding efficiency. At the same time, when the welding equipment is not in use, the electrodes are exposed and are easily damaged by external impacts or have foreign matter adhering to their surfaces, resulting in unevenness and affecting welding quality. To solve the above problems, a new automotive body sheet metal welding equipment is needed.

[0003] An existing automotive body sheet metal welding device is prone to electrode-sheet metal adhesion during operation, causing the electrodes to stick together and become difficult to separate, thus reducing welding efficiency. When not in use, the electrodes are exposed and their surfaces cannot be protected, which can easily lead to abnormal wear or foreign matter adhering to the surface, affecting the quality of subsequent welding. Therefore, there is an urgent need for an automotive body sheet metal welding device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an automotive body sheet metal welding device to solve the problems of existing automotive body sheet metal welding devices, which are prone to electrode and sheet metal parts sticking together during the welding process, making it difficult to separate the electrode and sheet metal parts, thereby reducing welding efficiency. In the off-duty state, the electrode is exposed and cannot protect its surface, which can easily cause abnormal wear or foreign matter to adhere to the surface, affecting the subsequent welding quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive body sheet metal welding device, comprising a body, a limit rod installed on the inner wall of the body, a slot formed on the inner side wall of the body, a welding arm installed on the outer wall of the limit rod, locking blocks installed on both sides of the outer wall of the welding arm, handles installed on both sides of the outer wall of the welding arm, a power cord electrically connected to the outer wall of the welding arm, an electrode installed on the outer wall of the welding arm, a positioning rod installed on the inner wall of the welding arm, a return spring installed on the outer wall of the positioning rod, a positioning groove formed on the outer wall of the welding arm, a protective sleeve installed on the outer wall of the welding arm, a silicone locking strip installed on the inner side wall of the protective sleeve, and a locking plate installed on the inner wall of the protective sleeve.

[0006] Preferably, the limiting rod is movably connected to the welding arm, and the locking block is engaged with the locking slot.

[0007] Preferably, the welding arm forms a telescopic structure with a return spring and a positioning rod, and the positioning rod is symmetrically arranged with the central axis of the welding arm as the center.

[0008] Preferably, the protective sleeve is sleeved with the welding arm, and the silicone clip is engaged with the positioning groove.

[0009] Preferably, the inner wall of the card plate is provided with a U-shaped groove, and the card plate is in close contact with the electrode.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through its body, limiting rod, slot, welding arm, locking block, handle, power cord, electrode, positioning rod, and return spring, aligns the electrode with the welding point. Then, both hands simultaneously press the handles on both sides to bring the electrode into contact with the welding point of the sheet metal part. At this time, the power cord is used to energize and weld. During the welding process, the sheet metal part and the electrode surface are easily burned and stuck due to high temperature, making it difficult to separate the electrode from the sheet metal part. At this time, by releasing the handle, the welding arm is pushed outward by the elastic force of the return spring, thereby applying a certain force to the electrode to assist in separating the electrode from the surface of the sheet metal part, thus improving the efficiency of continuous welding.

[0012] 2. This utility model, through the setting of electrodes, positioning grooves, protective sleeves, silicone clips, and clamping plates, allows the protective sleeve to be fitted onto the welding arm when the device is not in use. At this time, the silicone clips engage with the positioning grooves, and the clamping plates wrap and support the electrodes, protecting the electrode surface and preventing damage from external force collisions, as well as foreign objects adhering to the surface, which would cause unevenness and affect the subsequent welding quality.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Please see Figures 1-4 A welding device for automotive body sheet metal includes a body 1. A limit rod 2 is installed on the inner wall of the body 1. A slot 3 is formed on the inner side wall of the body 1. A welding arm 4 is installed on the outer wall of the limit rod 2. Locking blocks 5 are installed on both sides of the outer wall of the welding arm 4. Handles 6 are installed on both sides of the outer wall of the welding arm 4. A power cord 7 is electrically connected to the outer wall of the welding arm 4. An electrode 8 is installed on the outer wall of the welding arm 4. A positioning rod 9 is installed on the inner wall of the welding arm 4. A return spring 10 is installed on the outer wall of the positioning rod 9. The limit rod 2 is movably connected to the welding arm 4. The locking blocks 5 engage with the slot 3. The welding arm 4 forms a telescopic structure with the positioning rod 9 via the return spring 10, and the positioning rod 9 is centered on the central axis of the welding arm 4. The welding process involves aligning electrode 8 with the welding point using the following components: body 1, limit rod 2, slot 3, welding arm 4, locking block 5, handle 6, power cord 7, electrode 8, positioning rod 9, and return spring 10. Both hands simultaneously press the handles 6 on both sides to bring electrode 8 into contact with the sheet metal welding point. Power is then supplied through the power cord 7 for welding. During welding, high temperatures can cause the sheet metal to stick to the electrode 8, making separation difficult. Releasing the handles 6 allows the welding arm 4 to push outwards via the return spring 10, applying force to electrode 8 to help separate it from the sheet metal surface, thus improving continuous welding efficiency.

[0021] Please see Figures 1-4 A welding device for automotive body sheet metal includes a positioning groove 11 on the outer wall of a welding arm 4, a protective sleeve 12 installed on the outer wall of the welding arm 4, a silicone strip 13 installed on the inner side wall of the protective sleeve 12, and a clamping plate 14 installed on the inner wall of the protective sleeve 12. The protective sleeve 12 is sleeved with the welding arm 4, and the silicone strip 13 is engaged with the positioning groove 11. The inner wall of the clamping plate 14 is U-shaped and is tightly fitted with the electrode 8. In the device's off-state state, the protective sleeve 12 is sleeved with the welding arm 4, the silicone strip 13 is engaged with the positioning groove 11, and the clamping plate 14 wraps and supports the electrode 8, protecting the surface of the electrode 8 from damage caused by external impact and foreign matter adhering to the surface, which would result in unevenness and affect the subsequent welding quality.

[0022] Working principle: In use, first align the sheet metal parts to be welded, then align the electrode 8 with the welding point, and then press the handles 6 on both sides simultaneously to make the electrode 8 contact the welding point of the sheet metal part. At this time, power is supplied through the power cord 7 to perform welding. During the welding process, the sheet metal part and the surface of the electrode 8 may burn and stick due to high temperature, making it difficult to separate the electrode 8 from the sheet metal part. At this time, by releasing the handles 6, the welding arm 4 is pushed outward by the elastic force of the return spring 10, thereby applying a certain force to the electrode 8 to help separate the electrode 8 from the surface of the sheet metal part, thus improving the efficiency of continuous welding. When the device is not in use, the protective sleeve 12 is sleeved on the welding arm 4. At this time, the silicone strip 13 is engaged with the positioning groove 11, and the clamping plate 14 wraps and supports the electrode 8, protecting the surface of the electrode 8 from damage by external force collision and foreign objects adhering to the surface, which would cause unevenness and affect the subsequent welding quality. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
