[0038] A metal basket is welded together from an L-shaped metal strip and a metal hoop. The L-shaped strip is arranged circumferentially to form a cylindrical structure. The metal hoop is fitted over the cylindrical structure and connected by welding. The prior art lacks a fixture for securing the L-shaped strip and hoop. Traditional welding methods rely on manual securing and positioning, resulting in low welding efficiency. Therefore, there is an urgent need for a fixture for securing the L-shaped strip and hoop to improve welding efficiency.

[0039] In response to the problems existing in the above-mentioned prior art, the present application proposes a welding and fixing device, which places and positions the first bent portion of the "L-shaped" metal bar through a linear groove arranged on the support platform. Since one end of the linear groove points to the center of the support platform and the linear groove is arranged circumferentially along the support platform, multiple "L-shaped" metal bars are placed on the support platform and positioned to form a cylindrical structure. The second bent portion of the "L-shaped" metal bar is along the vertical direction. At the same time, a supporting portion for supporting the metal hoop is provided on the first support column of the base. The metal hoop is preferentially placed on the supporting portion, and then the first bent portion of multiple "L-shaped" metal bars is placed on the support platform and fixed by a fixing component so that the second bent portion abuts the outer wall of the metal hoop. After fixation, a welding machine can be used for welding. The operation of fixing the "L-shaped" metal bar and the metal hoop is convenient and efficient.

[0040] Reference Figure 1 and Figure 2 It is understood that the welding fixture provided by one embodiment of the present invention includes a base 200, a support platform 300, and a fixing component 140. The base 200 is provided with a first support column 220, the support platform 300 is disposed on the top of the first support column 220, and the fixing component 140 is detachably disposed on the top of the support platform 300. The first support column 220 is provided with a support portion 240, which protrudes radially from the first support column 220. The support portion 240 is provided with a support block 260 protruding radially from the first support column 220. The metal hoop 130 can be placed on the support block 260. A plurality of support portions 240 are arranged in a vertical direction. A plurality of linear grooves 310 are provided on the top of the support platform 300. One end of the linear groove 310 points to the center of the support platform 300, and the other end extends outward to the edge of the support platform 300. The plurality of linear grooves 310 are arranged circumferentially along the support platform 300. The first bent portion 110 of the "L-shaped" metal strip 100 can be embedded in the linear groove 310 to achieve positioning. After the metal hoop 130 and the "L-shaped" metal strip 100 are placed, the second bent portion 120 abuts against the outer side of the metal hoop 130. After the metal hoop 130 and the "L-shaped" metal strip 100 are placed, the fixing component 140 is covered on the top of the support platform 300 to fix the "L-shaped" metal strip 100. Figure 10As shown, the metal strip is an “L-shaped” metal strip 100 .

[0041] Reference Figure 3 It is understood that the support portion 240 is provided with a slide groove 250, and the support block 260 is slidably disposed within the slide groove 250, so that the support block 260 can be extended and retracted along the radial direction of the first support column 220. Furthermore, the support block 260 is provided with a lever 270, which protrudes vertically from the support portion 240. When placing the metal hoop 130, it is necessary to start from the support portion 240 at the bottom. To do this, the support block 260 at the top needs to be retracted into the support portion 240 to prevent the upper support block 260 from obstructing the metal hoop 130.

[0042] Reference Figure 1 、 Figure 4 、 Figure 5 and Figure 6 It can be understood that the base 200 is provided with a connecting rod 280, the connecting rod 280 is parallel to the first support column 220, and there are two connecting rods 280. The two connecting rods 280 are respectively located on both sides of the first support column 220, and a clamping member 400 is provided at one end of the connecting rod 280 close to the fixing part 140, that is, the end of the connecting rod 280 away from the base 200, and the clamping member 400 is used to clamp the fixing part 140.

[0043] It should be noted that the clamping member 400 includes a connecting member 410 and a clamping member 420. The connecting member 410 is arranged on the connecting rod 280. The clamping member 420 is provided with a rotating part 421, a clamping part 422 and a toggle part 423. The rotating part 421 is rotatably connected to the connecting member 410, and the two are specifically connected through a rotating shaft. The clamping part 422 and the toggle part 423 are respectively located on both sides of the rotating part 421. The clamping part 422 and the toggle part 423 can rotate around the rotating part 421, and when the clamping part 422 rotates, the toggle part 423 will rotate synchronously. The connecting member 410 is provided with a push rod 430, one end of which is rotatably connected to the connecting member 410. The toggle portion 423 is provided with a groove 424. When it is necessary to compress the fixing member 140, the pressing portion 422 is rotated clockwise until it abuts the fixing member 140, and then the toggle portion 423 is synchronously rotated to a position where the push rod 430 can be locked into the groove 424. The push rod 430 locks the toggle portion 423, making it impossible for the pressing member 420 to rotate counterclockwise to release the fixing member 140. When it is necessary to release the compressed state, the pressing portion 422 is further rotated clockwise until the push rod 430 can be disengaged from the groove 424, and then the push rod 430 is rotated to release the limit on the toggle portion 423, and finally the pressing member 420 is rotated counterclockwise.

[0044] It should be noted that if Figure 11As shown, groove 424 is a V-shaped groove, and a rubber pad 431 is provided at the end of push rod 430. The V-shaped groove allows push rod 430 to be inserted into the V-shaped groove only at a predetermined angle, and rubber pad 431 acts as a buffer and increases friction. In other embodiments, groove 424 may be a trapezoidal groove or other different types of grooves 424.

[0045] Reference Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 It can be understood that the connecting rod 280 is provided with a ferrule 290, the inner radius of the ferrule 290 is greater than the distance from the end of the support portion 240 to the central axis of the first support column 220, and the ferrule 290 is used to enclose the second bent portion 120. After the "L-shaped" metal strip 100 is placed, the inner ring side wall of the ferrule 290 abuts against the outer side wall of the "L-shaped" metal strip 100. The provision of the ferrule 290 can better shape the "L-shaped" metal strip 100 and the metal hoop 130. Further, as Figure 7 and Figure 8 As shown, the ring 290 is provided with a slot 291 , and the slot 291 is used to fix the second bending portion 120 .

[0046] Reference Figure 4 、 Figure 5 and Figure 8 It can be understood that the base 200 is provided with a fixing groove 210, the end of the second bent portion 120 is embedded in the fixing groove 210, the support platform 300 is provided with a second support column 330, the first support column 220 is provided with a mounting groove 230, the second support column 330 is embedded in the mounting groove 230 and can rotate in the mounting groove 230, and the base 200 is provided with a driving motor that can drive the second support column 330 to rotate, thereby rotating the support platform 300. Since the end of the second bent portion 120 is embedded in the fixing groove 210 and is fixed, when the support platform 300 rotates, the first bent portion 110 will rotate accordingly, thereby causing the second bent portion 120 to twist, and after twisting, it is welded to form a structure as shown in FIG. Figure 9 The metal basket shown in FIG. 1 can be twisted to change the shape of the gap in the metal basket so that objects of different shapes can be loaded therein.

[0047] Reference Figure 2 It is understood that the support platform 300 is also provided with an annular groove 320, the center of which coincides with the center of the support platform 300, and the annular groove 320 is used to fix the bottom ring. Adding a welded bottom ring to the metal basket can effectively enhance the structural strength of the bottom of the metal basket.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
