Description

Technical Field

[0001] This utility model relates to the field of electrode arm technology, specifically a water-cooled electrode arm. Background Technology

[0002] Electrode arms are widely used in welding and other hot working processes. Their main function is to fix and conduct current to the welding electrode or workpiece. In these applications, the electrode arms are subjected to high temperatures, so an effective cooling system is crucial for maintaining electrode performance and lifespan.

[0003] Traditional water-cooled electrode arms typically employ a one-piece design. While this design is simple in structure, it has several significant drawbacks in practical use. First, because the entire electrode arm must be molded in a single piece, material utilization during manufacturing is low, resulting in some waste. Second, because the cooling water path is fixed and cannot be adjusted, the cooling effect is limited, especially when a larger cooling area is required, where traditional designs often fail to meet the requirements. Furthermore, when the cooling system fails, the one-piece design necessitates replacing the entire electrode arm, leading to unnecessary waste.

[0004] With the development of industrial technology, higher requirements have been placed on the cooling efficiency of electrode arms, especially in automated and continuous operation environments. An efficient cooling system can significantly improve equipment efficiency and reduce failure rates caused by overheating. Therefore, developing a new type of water-cooled electrode arm that can overcome the aforementioned shortcomings and has better cooling performance and lower production costs has become an urgent need in the industry. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a water-cooled electrode arm.

[0006] The technical solution adopted by this utility model is as follows: a water-cooled electrode arm, including an electrode fixing post, an electrode hole provided at the center of the electrode fixing post, an electrode installed in the electrode hole, and a water-cooling assembly, the water-cooling assembly including a clamping block one, a clamping block two, a water inlet connector and a water outlet connector, the clamping block one and the clamping block two are provided with fixing holes for fixing the clamping block one and the clamping block two together, the clamping block one is provided with a surrounding hole covering the outer wall of the electrode fixing post, the electrode fixing post is provided with a notch for clamping block two to be inserted, the bottom surface of clamping block two installed in the notch is in contact with the electrode, the clamping block two is provided with a first cooling water channel, a second cooling water channel and a connecting water channel for connecting the first cooling water channel and the second cooling water channel, the opening of the first cooling water channel is connected to the above-mentioned water inlet connector, and the opening of the second cooling water channel is connected to the above-mentioned water outlet connector.

[0007] Furthermore, the first cooling water channel and the second cooling water channel are arranged in parallel on the upper and lower sides of the clamping block two.

[0008] Furthermore, the clamping block is provided with a positioning screw hole, and the electrode fixing post is provided with a matching positioning hole.

[0009] Furthermore, the assembled clamping block one and clamping block two form a cube or cuboid structure.

[0010] Furthermore, it also includes a locking nut, one end of the electrode fixing post has a tapered chuck, the tapered chuck has a slot in the middle, the locking nut has a pressing slope for tightening the tapered chuck, and the locking nut is threaded to one end of the electrode fixing post.

[0011] Furthermore, the outer wall slope of the conical chuck is 10-15 degrees, and the slope of the pressing slope is 15-20 degrees.

[0012] The beneficial effects of the utility model are:

[0013] 1. Material and cost savings: The new design allows the water channel fixing blocks (clamp block one and clamp block two) to be manufactured independently of the electrode arm, so that the water channel part can be replaced or repaired individually as needed without replacing the entire electrode arm, thereby reducing production and maintenance costs.

[0014] 2. Enhanced cooling performance: By setting notches on the electrode fixing posts, the clamping blocks installed on the notches are made to fit against the electrodes inside the electrode fixing posts, allowing for direct water cooling of the electrodes. This increases the cooling area, allowing the electrode temperature to drop more quickly, improving the cooling effect, and thus increasing the service life and working efficiency of the electrodes.

[0015] 3. Improved maintenance convenience: The split design simplifies the maintenance of the cooling system. When a component is damaged, only the damaged part needs to be replaced, without replacing the entire motor, thus reducing operating costs.

[0016] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] This invention provides a water-cooled electrode arm.

[0028] In this embodiment, refer to Figure 1-6The water-cooled electrode arm includes an electrode fixing post 1 with an electrode hole 13 at its center. An electrode 14 is installed in the electrode hole 13. The water-cooling assembly includes a clamping block 2, a clamping block 3, an inlet connector 4, and an outlet connector 5. The clamping block 2 and the clamping block 3 are provided with fixing holes 6 for fixing the clamping block 2 and the clamping block 3. The clamping block 2 is provided with a surrounding hole 7 covering the outer wall of the electrode fixing post. The electrode fixing post 1 is provided with a notch 19 for the clamping block 2 to be inserted. The bottom surface of the clamping block 2 3 installed in the notch is in contact with the electrode 14. The clamping block 2 is provided with a first cooling water channel 8, a second cooling water channel 9, and a connecting water channel 10 for connecting the first cooling water channel and the second cooling water channel. The opening of the first cooling water channel is connected to the inlet connector, and the opening of the second cooling water channel is connected to the outlet connector.

[0029] This application separates the water-cooling assembly from the electrode fixing post, allowing the water channel fixing blocks (clamp block one and clamp block two) to be manufactured and installed independently, thus improving material utilization. In the event of damage to a component (such as clamp block one, clamp block two, or the electrode arm), the cooling assembly can be replaced individually, avoiding unnecessary waste and reducing operating costs. Clamp block two (containing cooling water channels) is positioned on the notch of the electrode fixing post and fits snugly against the electrode, increasing the cooling area, improving the cooling effect, and extending the electrode's service life.

[0030] Specifically, the first cooling water channel and the second cooling water channel are arranged in parallel on the upper and lower sides of the clamping block 2.

[0031] The parallel arrangement of the first and second cooling water channels ensures a uniform distribution of cooling water flow, improves cooling efficiency, simplifies the water circuit layout, and facilitates maintenance and repair.

[0032] Specifically, the clamping block is provided with a positioning screw hole 11, and the electrode fixing post is provided with a matching positioning hole 12.

[0033] The use of positioning screw holes and positioning holes ensures precise installation between the water-cooling components and the electrode fixing posts, avoiding problems such as cooling failure or insecure electrode fixing caused by improper installation.

[0034] Specifically, the assembled clamping block one and clamping block two form a cube or cuboid structure.

[0035] The cubic or cuboid structural design makes the water-cooled components have a regular shape, which helps to improve space utilization and facilitates integration and fixing onto the mounting surface of various equipment. It also makes transportation and storage convenient.

[0036] Specifically, it also includes a locking nut 15, a tapered chuck 16 on one end of the electrode fixing post, a slot 17 in the middle of the tapered chuck 16, and a tightening inclined surface 18 for tightening the tapered chuck inside the locking nut. The locking nut is threadedly connected to one end of the electrode fixing post.

[0037] The combination of the locking nut and the tapered chuck utilizes the interaction between the slotted tapered chuck and the inclined surface inside the nut. During the tightening of the locking nut, the tapered chuck can be contracted to tighten and fix the electrode, ensuring a firm fixation of the electrode and facilitating adjustment and disassembly.

[0038] Specifically, the outer wall slope of the conical chuck is 10-15 degrees, and the slope of the pressing slope is 15-20 degrees.

[0039] The tapered chuck with a specific angle and the pressure slope achieve optimal clamping force, ensuring that the electrode will not loosen due to vibration, while also facilitating the installation and removal of the electrode.

[0040] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
