[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] See Figures 1-5 This utility model discloses an adjustable welding clamping fixture, including a clamping platform 10 and two positioning clamping assemblies 20. Both positioning clamping assemblies 20 are mounted on the clamping platform 10, and are spaced apart along the length of the clamping platform 10. Each positioning clamping assembly 20 includes a positioning slide 23, a first positioning mechanism 21, and a second positioning mechanism 22. The positioning slide 23 extends along the width of the clamping platform 10 and can slide along its length. The first positioning mechanism 21 and the second positioning mechanism 22 are both mounted on the positioning slide 23. The two positioning slides 23 slide along the length of the clamping platform 10, and the distance between the first positioning mechanism 21 and the second positioning mechanism 22 on the two positioning slides 23 along the length of the clamping platform 10 can be adjusted.

[0027] Specifically, the first positioning mechanism 21 includes two first positioning seats 211, both of which are mounted on the positioning slide 23 and are spaced apart on the positioning slide 23; the first positioning seats 211 and the positioning slide 23 are slidably engaged. The second positioning mechanism 22 includes two second positioning seats 221, which are respectively disposed on the outside of the two first positioning seats 211, and at least one second positioning seat 221 is slidably engaged with the positioning slide 23.

[0028] Since the positioning slide 23 extends in the width direction of the clamping table 10, and the two first positioning seats 211 mounted on the positioning slide 23 can slide and engage with the positioning slide 23, the distance between the two first positioning seats 211 in the width direction of the clamping table 10 can be adjusted. At the same time, the two second positioning seats 221 are also mounted on the positioning slide 23, and the distance between the two first positioning seats 211 and the two second positioning seats 221 can be adjusted. Moreover, at least one second positioning seat 221 can slide relative to the positioning slide 23, so the distance between the two second positioning seats 221 in the width direction of the clamping table 10 can also be adjusted.

[0029] Based on this structure, when using the adjustable welding clamping fixture of this utility model to clamp the workpiece, When the workpiece is large, both its length and width are large, the two positioning slides 23 can be slid apart along the length of the clamping table 10. This increases the distance between the two positioning slides 23 along the length of the clamping table 10, and the long side of the workpiece can be positioned by the distance between the two positioning slides 23.

[0030] Since the two second positioning seats 221 of the second positioning mechanism 22 on the positioning slide 23 are located between the two first positioning seats 211 of the first positioning mechanism 21, the distance between the two second positioning seats 221 in the width direction of the clamping table 10 is greater than the distance between the two first positioning seats 211. Therefore, the workpiece has a larger width dimension and can be positioned by the two second positioning seats 221 on the positioning slide 23.

[0031] When the workpiece is placed, the long side of the workpiece can be adapted to the distance between the two positioning slides 23, so that the two widths of the workpiece can be supported by the second positioning mechanism 22 on the two positioning slides 23 respectively, and the two second positioning seats 221 on each positioning slide 23 can be adapted to the width length of the workpiece.

[0032] When the workpiece is large, the two second positioning seats 221 support and position it at the wide end of the workpiece, while the two first positioning seats 211 located between the two second positioning seats 221 can slide to the middle position of the wide side for support, thus preventing collapse during welding at the middle position of the wide side of the workpiece. Both first positioning seats 211 can slide, providing support at their respective positions.

[0033] When the workpiece size is small, the two second positioning seats 221 may slide to the closest position or may be larger than the width of the workpiece. In this case, the two first positioning seats 211 can be slid to make the distance between the two first positioning seats 211 match the width of the small workpiece, so that the two first positioning seats 211 can be used to position and support the width of the workpiece.

[0034] Of course, when the wide side of the workpiece is placed on the two first positioning seats 211 for positioning support, the second positioning seat 221 can slide close to the first positioning seat 211 and abut against the outer side of the workpiece to achieve dual positioning, making the positioning structure more stable.

[0035] Thus, in this application, the two positioning slides 23 can slide relative to each other, so that the distance between the first positioning mechanism 21 and the second positioning mechanism 22 on the positioning slide 23 can be adapted to the adjustment of the long side dimension of the workpiece. The distance between the two first positioning seats 211 of the first positioning mechanism 21 on the positioning slide 23 can be adjusted according to the smaller wide side dimension, and the distance between the two second positioning seats 221 of the second positioning mechanism 22 can be adjusted according to the larger wide side dimension, which is suitable for more sizes of workpieces.

[0036] Furthermore, when using two second positioning seats 221 for positioning support, the two first positioning seats 211 can provide auxiliary support positioning in the middle position. When using two first positioning seats 211 for positioning support, the two second positioning seats 221 can provide auxiliary support positioning on the outer side, thus making the workpiece positioning more stable.

[0037] As an optional implementation, a positioning plate can also be provided on the first positioning seat 211. The positioning plate extends along the height direction of the clamping table 10. After the workpiece is placed on the first positioning seat 211, the bottom edge of the workpiece can be positioned and supported by the first positioning seat 211. The positioning plate on the first positioning seat 211 can abut against the inner or outer side of the workpiece and be positioned with the positioning plate of another first positioning seat 211 on the inner or outer side to achieve positioning and clamping.

[0038] Specifically, a positioning block 214 and a lifting drive can be provided on the first positioning seat 211. The lifting drive is installed on the outside of the positioning plate and connected to the positioning block 214. The lifting drive is used to drive the positioning block 214 to move along the height direction of the clamping table 10. In this way, when positioning and supporting, the inner side of the workpiece can be supported and abutted by the positioning plate, while the positioning block 214 can move upward under the drive of the lifting drive to abut and support the fixed side of the workpiece. In this way, the workpiece is not easy to collapse during welding, and the positioning and clamping is more stable.

[0039] More specifically, a first limiting plate 215 may be provided on the first positioning seat 211, and a plurality of first limiting holes 231 may be provided on the positioning slide 23, the plurality of first limiting holes 231 being spaced apart in the extending direction of the positioning slide 23; the first limiting plate 215 may be provided with a first limiting structure 216, the first limiting structure 216 being configured to correspond to one of the limiting holes 231.

[0040] The first limiting structure 216 mentioned above may include a first strip hole and a first limiting pin (not shown in the figure). When the first positioning seat 211 slides to the corresponding positioning position, the first strip hole can correspond to the first limiting hole 231 of the positioning slide 23. Then, the first limiting pin passes through the first strip hole and is inserted into the first limiting hole 231 to position the first positioning seat 211. This can prevent the workpiece from shifting during the positioning welding process.

[0041] As an optional implementation, a positioning piece can be provided on the second positioning seat 221. The positioning piece extends along the height direction of the clamping table 10. The top of the positioning piece is provided with an inclined guide section 224 that bends outward. In this way, when the second positioning seat 221 positions the workpiece, the positioning piece can abut against the inner side of the workpiece. When the bottom end of the workpiece contacts the positioning piece, the inclined guide section 224 at the top of the positioning piece can slide inward along the guide workpiece to the positioning piece and abut against the side of the workpiece. This facilitates the clamping and abutment of the workpiece with the positioning piece.

[0042] More specifically, the aforementioned positioning plates are provided in three parts: a first positioning plate 222 and two second positioning plates 223. The two second positioning plates 223 are spaced apart in the width direction of the second positioning base 221, and the first positioning plate 222 is located between the two second positioning plates 223 and spaced apart from the two second positioning plates 223 in the length direction of the second positioning base 221. In this way, when positioning the workpiece, the wide side of the workpiece can be positioned and abutted by the first positioning plate 222 and the second positioning plate 223 in two directions, thus preventing the workpiece from shaking after clamping and making the clamping structure more stable.

[0043] As an optional implementation, a positioning rod 225 can also be provided on the second positioning seat 221. The positioning rod 225 is located between the three positioning plates. After the workpiece is placed on the second positioning seat 221, if the workpiece has a through hole, the positioning rod 225 can pass through the hole of the workpiece for positioning, which makes the positioning more accurate.

[0044] As an optional implementation, one of the second positioning seats 221 is fixedly disposed at the end of the positioning slide 23; the other second positioning seat 221 is slidably engaged with the positioning slide 23; and a second limiting plate 227 is disposed on the other second positioning seat 221, the second limiting plate 227 is provided with a second limiting structure 228, the second limiting structure 228 is used to correspond to one of the limiting holes 231.

[0045] It should be noted that the second limiting structure 228 may include a second strip hole and a second limiting pin (not shown in the figure). When the second positioning seat 221 slides to the corresponding positioning position, the second strip hole may correspond to the second limiting hole 231 of the positioning slide 23. Then, the second limiting pin passes through the second strip hole and is inserted into the second limiting hole 231 to position the second positioning seat 221. This can prevent the workpiece from shifting during the positioning welding process.

[0046] As an optional implementation, the bottom of both ends of the positioning slide 23 is provided with a first slider 232, and both sides of the clamping table 10 are provided with a first slide rail 11, both of which extend along the length of the clamping table 10; the first slider 232 slides in cooperation with the first slide rail 11; a third limiting plate is provided on the positioning slide 23, and the third limiting plate is provided with a third limiting structure. In this way, when the positioning slide 23 slides, it can slide by the first slider 232 at both ends of the positioning slide 23 sliding in cooperation with the first slide rail 11 on both sides of the clamping table 10, so that the relative sliding of the two positioning slides 23 is more stable.

[0047] As an optional implementation, the bottom end of the first positioning seat 211 and at least one second positioning seat 221 is provided with a second slider 226, and the positioning slide 23 is provided with a second slide rail 233, which extends along the width direction of the clamping table 10; the second slider 226 and the second slide rail 233 are slidably engaged.

[0048] In this way, when the first positioning seat 211 or the second positioning seat 221 slides relative to the positioning slide 23, the sliding guidance can be achieved through the sliding cooperation between the second slider 226 and the second slide rail 233, making the sliding process of the first positioning seat 211 or the second positioning seat 221 more stable.

[0049] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
