Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary tools, in particular to a tungsten rod clamping device. Background Art

[0002] Argon arc welding technology is a commonly used technology in the field of metal welding. It is a welding technology based on the principle of ordinary arc welding. It uses argon gas to protect metal welding materials. Through high current, the welding materials are melted into liquid on the base material to form a molten pool, so that the metal to be welded and the welding materials can achieve metallurgical bonding. Because argon gas is continuously supplied during high-temperature molten welding, the welding materials cannot come into contact with oxygen in the air, thereby preventing the oxidation of the welding materials. Therefore, stainless steel and iron hardware metals can be welded.

[0003] A Chinese utility model patent (CN212239557U) discloses a tungsten rod clamping device, including an outer sleeve, a clamping slit is provided at the left end of the outer sleeve, a fixing block is integrally processed on the surface of the outer sleeve, an external thread is provided on the surface of the outer sleeve, and the external thread is located at the right end of the outer sleeve, the fixing block is located on the left side of the external thread and butted against the external thread, and a clamping cavity is provided inside the outer sleeve.

[0004] However, the clamping devices in the prior art are mostly single tungsten rods directly connected to the rotor for welding, and special parts cannot be welded; some tungsten rods with multi-section designs are complicated to disassemble and position, and it is not convenient to adjust the state position; the tungsten rod hole direction angle is single, and it is not convenient to replace parts with different hole directions; the tungsten rod welding position is not well fixed due to the disassembly and assembly screws, resulting in the tungsten rod welding position offset, and the welding degree of the product is different.

[0092] It should be noted that the number of the first mounting holes 211 is two, and the two first mounting holes 211 are arranged in a crosswise manner, that is, the parts of the two first mounting holes 211 are in communication with each other.

[0093] Specifically, the first insertion hole 212 is vertically formed in the first clamping member 210, and the second end of the connecting member 120 can pass through the first insertion hole 212.

[0094] It should be noted that the axial direction of the first insertion hole 212 is the same as the height direction of the first clamping member 210.

[0107] Embodiment 2

[0108] This embodiment is a variant embodiment of Embodiment 1. The main difference between this embodiment and Embodiment 1 is that the structure of the tungsten rod clamping structure 200 is different.

Among them, the second clamping member 230 is rotatably connected to the rotating connection structure 100 for mounting the tungsten rod; the second fixing member 240 is connected to the second clamping member 230, and the end of the second fixing member 240 abuts against the tungsten rod for fixing the tungsten rod.

[0111] In some of these embodiments, the second clamping member 230 includes, but is not limited to, a metal arc-shaped plate.

[0112] Specifically, the second fixing member 240 is threadedly connected to the side of the second clamping member 230, and the end of the second fixing member 240 can abut against the tungsten rod inserted on the second clamping member 230 to fix the tungsten rod on the second clamping member 230.

[0113] In some of these embodiments, the second fixing member 240 includes, but is not limited to, a bolt.

[0114] Furthermore, the second clamping member 230 further includes a second mounting hole 231, an insertion slot 232, a second fixing hole 233, and a plurality of second locking holes 234. Among them, the second mounting hole 231 is opened in the second clamping member 230 for mounting a tungsten rod; the insertion slot 232 is opened in the second clamping member 230 for connecting the rotational connection structure 100; the second fixing hole 233 is opened in the second clamping member 230 and communicates with the second mounting hole 231 for mounting the second fixing member 240; the plurality of second locking holes 234 are opened in the second clamping member 230 and all communicate with the insertion slot 232 for mounting the locking structure 300.

[0118] Specifically, the second fixing hole 233 is opened on the side of the second clamping member 230, and the inner wall of the second fixing hole 233 has an internal thread structure, and this internal thread structure can be threadedly connected to the second fixing member 240.

[0119] It should be noted that the axial direction of the second fixing hole 233 is perpendicular to the axial direction of the second mounting hole 231.

[0120] Specifically, the second locking hole 234 is opened at a position on the second clamping member 230 relative to the insertion slot 232, and the inner wall of the second locking hole 234 has an internal thread structure, and this internal thread structure can be threadedly connected to the first locking member 310.

[0121] It should be noted that the axial direction of the second locking hole 234 is the same as the axial direction of the second fixing hole 233.

[0122] More specifically, the number of the second locking holes 234 is 3, and the 3 second locking holes 234 are spaced apart along the side wall of the insertion slot 232.

[0123] In some of these embodiments, the number of the second locking holes 234 may also be 2, 4, etc., that is, the number of the second locking holes 234 can be set according to actual requirements and will not be overly limited herein.

[0124] The usage method of this embodiment is as follows:

[0125] First, the staff threadedly connects the first end of the connecting member 120 to the corresponding first connection hole 111 on the rotating member 110.

[0126] Subsequently, the staff passes the second end of the connecting member 120 through the insertion slot 232 on the second clamping member 230 and adjusts the angle of the second clamping member 230. After determining the angle of the second clamping member 230, rotate the first locking member 310 so that the end of the first locking member 310 abuts against the connecting member 120 to fix the second clamping member 230.

[0127] Finally, the staff inserts the tungsten rod into the second mounting hole 231 on the second clamping member 230 and rotates the second fixing member 240 so that the end of the second fixing member 240 abuts against the tungsten rod to fix the tungsten rod.

[0128] The advantage of this embodiment is that by rotatably connecting the second clamping member to the second end of the connecting member, the staff can adjust the angle of the tungsten rod relative to the welding point by rotating the second clamping member, improving applicability.

[0129] Embodiment 3

[0135] In some of these embodiments, the third fixing member 260 includes, but is not limited to, a bolt.

[0136] Furthermore, the third clamping member 250 further includes a third mounting hole 251 and a third fixing hole 252.
