Description

Technical Field

[0001] This utility model belongs to the field of welding head technology, specifically a welding head fixing fixture. Background Technology

[0002] Welding heads are typically used to spot weld two or more metal parts together, such as two overlapping metal sheet parts. When using a welding head, it needs to be fixed to the welding machine using a fixture.

[0003] In existing technology, a welding head fixing seat for a welding machine, application number CN202420194639.7, allows for adjustment by moving the fixing seat forward and backward, and left and right through the cooperation of a first sliding groove, a second sliding groove, a first sliding bar, and a second sliding bar. However, during the use of the welding head, there may sometimes be a certain degree of parallelism deviation between the welding head and the workpiece being welded, resulting in incomplete welding and affecting the uniformity and strength of the weld. While the welding head fixing seat can move forward and backward, and left and right, it is not convenient to rotate. Moving it forward, backward, left, and right makes it difficult to adjust the parallelism between the welding head and the workpiece, thus affecting the overall welding effect. Therefore, we provide a welding head fixing fixture. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that while the welding head holder can move forward, backward, left, and right, it is not convenient to rotate, and that the forward, backward, left, and right movement makes it difficult to adjust the parallelism between the welding head and the workpiece being welded, thus affecting the overall welding effect, a welding head fixing fixture is proposed.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Specific implementation examples are given below.

[0039] Example 1:

[0040] Please see Figures 1 to 4 This utility model provides a welding head fixing fixture, including:

[0041] Fixed plate 1, and mounting plate 2 fixedly installed at the lower end of fixed plate 1;

[0042] Adjustment component 3 is installed at the front end of the fixed plate 1 and is used to adjust the parallelism of the welding head;

[0043] Mounting component 4 is installed on the lower left and right sides of mounting plate 2 and is used to mount the welding head onto mounting plate 2;

[0044] Locking component 5 is installed inside mounting component 4 and is used to fix the welding head to mounting component 4;

[0045] Auxiliary component 6 is installed inside the left side of mounting component 4 to provide assistance when the welding head is installed inside mounting component 4.

[0046] In this embodiment, the welding head is installed onto the mounting component 4 by locking component 5 to ensure the stability of the connection between the welding head and the mounting component 4. When the welding head is installed onto the mounting component 4, auxiliary component 6 helps to accurately locate the installation position of the welding head, which facilitates the installation of the welding head. Then, the mounting component 4 is installed onto the mounting plate 2 by the mounting component 4, thereby installing the welding head onto the mounting plate 2. The parallelism of the welding head is adjusted by adjusting component 3 to push the mounting component 4 to swing.

[0047] Example 2:

[0048] Based on Embodiment 1, the adjustment component 3 and the mounting component 4 are further disclosed.

[0049] like Figure 1 and Figure 2As shown, the adjusting component 3 includes: a fixing block 301 fixedly installed on the left and right sides of the front end of the fixing plate 1; a worm gear 302 rotatably connected between the fixing blocks 301; a worm wheel 303 meshing at the rear end of the worm gear 302; a lead screw 304 fixedly installed in the middle of the worm wheel 303; a stabilizing plate 305 fixedly installed in the middle of the lower end of the fixing plate 1; a pressure block 306 rotatably connected to the outside of the lead screw 304; and an adjusting rod 307 fixedly installed at the lower end of the pressure block 306. The mounting component 4 includes: a first connecting ring 401 snapped onto the front side of the lower end of the mounting plate 2; a second connecting ring 402 snapped onto the rear side of the lower end of the mounting plate 2; a locking block 403 fixedly installed on the side of the first connecting ring 401 and the second connecting ring 402 away from the central axis; a locking nut 404 threadedly connected to the lower end of the locking block 403; and a first spring 405 sleeved on the outside of the locking nut 404.

[0050] In this embodiment, when the mounting component 4 is installed onto the mounting plate 2, the first connecting ring 401 and the second connecting ring 402 are secured to the lower left and right sides of the mounting plate 2. Then, the locking nut 404 on the locking block 403 is loosened, causing the locking block 403 to move closer to the mounting plate 2. Tightening the locking nut 404 causes the upper end of the locking block 403 to engage with the lower end of the pressure block 306. As the locking nut 404 is tightened, it applies pressure to the first spring 405, thus fixing the first connecting ring 401 and the second connecting ring 402 and ensuring the stability of the welding head after installation. Simultaneously, the first spring 405 is positioned between the locking nut 404 and the locking block 403 to facilitate subsequent adjustment of the welding head's parallelism. When adjusting the parallelism of the welding head, the motor drives the worm gear 302 to rotate. The worm gear 302 rotates between the fixed blocks 301. The rear end of the worm gear 302 meshes with the worm wheel 303. As the worm gear 302 rotates, the worm wheel 303 also rotates, thereby driving the lead screw 304 to rotate. The stabilizing plate 405 improves the stability of the lead screw 304 when it rotates. The rotation of the lead screw 304 drives the pressure block 306 to press down. The adjusting rod 307 at the lower end of the pressure block 306 also presses down, thereby pushing the locking block 403 and causing the first connecting ring 401 and the second connecting ring 402 to rotate slightly, thereby driving the welding head to adjust its parallelism. This makes it easy to adjust the parallelism of the welding head according to the welding conditions.

[0051] Example 3:

[0052] Based on Embodiment 1, a locking component 5 is further disclosed.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, the locking component 5 includes: a mating block 501 fixedly installed at the rear end of the first connecting ring 401 and the front end of the second connecting ring 402; slots 502 are provided on the left and right sides of the rear end of the first connecting ring 401 and the left and right sides of the front end of the second connecting ring 402; a locking plate 503 is locked inside the slots 502; a mating block 504 is fixedly installed at the lower end of the first connecting ring 401 and the second connecting ring 402; an amplitude transformer 505 is locked between the first connecting ring 401 and the second connecting ring 402; a locking ring 506 is fixedly installed on the outside of the amplitude transformer 505; a retaining ring 507 is fixedly installed at the middle of the rear end of the first connecting ring 401 and the middle of the front end of the second connecting ring 402; and a through groove 508 is provided on one side of both the retaining ring 507 and the locking ring 506.

[0054] In this embodiment, when fixing the welding head onto the mounting assembly 4, the welding head is installed on the amplitude transformer 505. Then, the locking ring 506 on the amplitude transformer 505 is inserted between the retaining rings 507. Subsequently, the first connecting ring 401 and the second connecting ring 402 are fitted together, and the mating block 504 is also fitted together. The mating block 504 is fixed with a nut, and the fitting blocks 501 are fitted together. Then, the retaining plate 503 is inserted into the retaining groove 502, and the retaining plate 503 and the fitting block 501 are fixed with a nut. The through groove 508 on the locking ring 506 is connected to the through groove 508 on the retaining ring 507. Finally, it is fixed with a nut. This facilitates the assembly of the mounting assembly 4, as well as the disassembly and installation of the welding head, and the replacement and maintenance of the amplitude transformer 505 and the welding head.

[0055] Example 4:

[0056] Based on Embodiment 1, auxiliary component 6 is further disclosed.

[0057] like Figure 1 , Figure 3 and Figure 4 As shown, the auxiliary component 6 includes: a slide groove 601 opened inside the second connecting ring 402, a limit rod 602 slidably connected inside the slide groove 601, a second spring 603 provided between the limit rod 602 and the slide groove 601, and a limit groove 604 opened at the rear end of the locking ring 506.

[0058] In this embodiment, when the locking ring 506 on the luffing rod 505 is inserted between the retaining rings 507, the through groove 508 on the locking ring 506 and the through groove 508 on the retaining ring 507 are connected when the luffing rod 505 is rotated. When the locking ring 506 is inserted between the retaining rings 507, the locking ring 506 will squeeze the limiting rod 602 to slide into the sliding groove 601 and put pressure on the second spring 603. Then the luffing rod 505 is rotated. When the luffing rod 505 is rotated to the designated position, the limiting groove 604 is aligned with the sliding groove 601, the second spring 603 is reset, and the limiting rod 602 is ejected and locked into the limiting groove 604. This provides a certain resistance when the luffing rod 505 is rotated, reminding the operator that it has been rotated to the correct position, which facilitates the installation of the luffing rod 505.
