[0038] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0040] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the welding fixture or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] This application provides a welding fixture that can be used to clamp a workpiece to be welded. For example, the welding fixture can be used to clamp a pouch cell module in a battery to facilitate high-precision welding of the pouch cell module.

[0043] See Figure 1 A welding fixture includes a base 100, a support structure 200, an adjustment structure 300, and a clamping structure 400.

[0044] The support structure 200 is connected to the base 100 by an adjustment structure 300, which enables the support structure 200 to be adjusted in height on the base 100. The support structure 200 is used to support the workpiece 600.

[0045] For example, the height of the support structure 200 on the base 100 can be adjusted by adjusting the structure 300 according to the height of the workpiece 600 to be supported by the support structure 200.

[0046] The clamping structure 400 is detachably connected to the base 100. The clamping structure 400 is used to clamp the workpiece 600, and the clamping structure 400 is provided with a welding hole 421 for welding the workpiece 600.

[0047] Specifically, before the welding fixture is loaded with the workpiece 600, the height of the support structure 200 on the base 100 can be adjusted by adjusting the structure 300 according to the height of the workpiece 600. At the same time, the relative distance between the support structure 200 and the clamping member 420 is adjusted. After adjustment, the workpiece 600 can be placed on the support structure 200. Then, the clamping structure 400 is connected to the base 100 so that the clamping structure 400 can press the workpiece 600 onto the support structure 200. In subsequent processes, the welding device can weld the workpiece 600 through the welding hole 421.

[0048] It is understandable that since the connection position between the clamping structure 400 and the base 100 is fixed, the relative distance between the support structure 200 and the clamping structure 400 can be adjusted by adjusting the height position of the support structure 200.

[0049] In other words, in the welding fixture of this application, by setting the support structure 200 on the base 100 and connecting the support structure 200 and the base 100 through the adjustment structure 300, the adjustment structure 300 can adjust the height position of the support structure 200 on the base 100, so that the support structure 200 can support workpieces 600 of different heights. When the clamping structure 400 is set on the base 100, the clamping structure 400 can clamp the workpieces 600 of different heights onto the support structure 200, so that the welding fixture can be used for workpieces 600 of different heights. Furthermore, the workpieces 600 of different heights can be welded through the welding hole 421 on the clamping structure 400, thereby improving the compatibility of the welding fixture.

[0050] See Figure 1 The clamping structure 400 includes a cover 410 and a clamping member 420. The cover 410 is detachably connected to the base 100. The clamping member 420 is connected to the cover 410 and is used to clamp the workpiece 600. The clamping member 420 is provided with a welding hole 421 for welding the workpiece 600.

[0051] Specifically, before the welding fixture is loaded with the workpiece 600, the height of the support structure 200 on the base 100 can be adjusted by adjusting the structure 300 according to the height of the workpiece 600. At the same time, the relative distance between the support structure 200 and the clamping member 420 is also adjusted. After adjustment, the workpiece 600 can be placed on the support structure 200. Then, the cover 410 is connected to the base 100 so that the clamping member 420 connected to the cover 410 can press the workpiece 600 onto the support structure 200. In subsequent processes, the welding device can weld the workpiece 600 through the welding hole 421.

[0052] It is understandable that since the connection position between the cover 410 and the base 100 is fixed, the position of the clamping member 420 is also fixed. Therefore, the relative distance between the support structure 200 and the clamping member 420 can be adjusted by adjusting the height of the support structure 200.

[0053] See Figure 2 The base 100 may include oppositely arranged fasteners 110, and the support structure 200 is located between the fasteners 110, and the support structure 200 is connected to the fasteners 110 through an adjustment structure 300. This structure facilitates the support and installation of the support structure 200, and also facilitates the adjustment of the height of the support structure 200 through the adjustment structure 300, and the structure is simple.

[0054] For example, both ends of the support structure 200 can be connected to the corresponding fasteners 110 via the adjustment structure 300.

[0055] In some embodiments, in order to improve the stability of the connection between the support structure 200 and the base 100, the base 100 may include multiple sets of oppositely arranged fasteners 110, which may extend along the length direction of the support structure 200.

[0056] See Figure 2 The adjustment structure 300 may include a first adjustment hole 310 disposed on the fixing member 110 and a connector 320. Multiple first adjustment holes 310 are disposed at intervals along the height direction on the fixing member 110. One end of the connector 320 is connected to the support structure 200, and the other end is connected to the first adjustment hole 310 at the corresponding height.

[0057] It is understood that the support structure 200 can be adjusted to different heights depending on the height of the workpiece 600 to be installed, and the connecting piece 320 connected to the support structure 200 can be connected to the first adjustment hole 310 of the corresponding height, thereby fixing the support structure 200 to the fixing piece 110.

[0058] Furthermore, to facilitate the connection between the adjustment structure 300 and the fixing member 110 when adjusting the position of the support structure 200, see [reference needed]. Figure 4 The connector 320 may further include a main body 321, a first connecting part 322, and a second connecting part 323. The first connecting part 322 is connected to the main body 321, and a first angle is formed between the first connecting part 322 and the main body 321. The first connecting part 322 is connected to the support structure 200. The second connecting part 323 is connected to the end of the main body 321, and a second angle is formed between the second connecting part 323 and the main body 321. The main body 321 abuts against the first side surface 111 of the fixing member 110. A first adjusting hole 310 is provided in the second side surface 112 of the fixing member 110 adjacent to the first side surface 111. The second connecting part 323 is connected to the first adjusting hole 310.

[0059] It is understood that by adjusting the height of the support structure 200, the first connecting part 322 can be easily connected to the connecting piece 320 and the support structure 200. By setting the second adjusting hole 211 on the second side 112 of the fixing piece 110 and making the second connecting part 323 and the main body 321 form an angle connection, the connecting piece 320 can be easily connected to the first adjusting hole 310. The second connecting part 323 can be connected to the first adjusting hole 310 by bolts or the like.

[0060] In some embodiments, the first included angle between the first connecting portion 322 and the main body portion 321 can be 90°, and the second included angle between the second connecting portion 323 and the main body portion 321 can be 90°.

[0061] In order to improve the stability of the connection between the second connecting part 323 and the fastener 110, the two ends of the main body 321 may be respectively connected with the second connecting part 323.

[0062] Furthermore, a position scale 330 can be provided on the fastener 110 along the height direction. It can be understood that the position scale 330 can conveniently determine the height position of the support structure 200.

[0063] Preferably, the position scale 330 is disposed on the third side 113 of the fixing member 110, and the third side 113 is opposite to the first side 111. It can be understood that since the second connecting part 323 is connected to the first adjusting hole 310 disposed on the second side 112, and the second connecting part 323 is connected to the second side 112 of the fixing member 110, the position of the second connecting part 323 can be easily observed during the connection process between the second connecting part 323 and the first adjusting hole 310. At the same time, the above-mentioned position setting also facilitates the setting of the position scale 330.

[0064] See Figure 3In one embodiment, the clamping structure 400 may further include an elastic element 430, and the clamping element 420 is connected to the cover 410 through the elastic element 430. It is understood that when the clamping element 420 clamps the workpiece 600 onto the support structure 200, the elastic element 430 can cushion the clamping element 420 to prevent the clamping element 420 from damaging the workpiece 600.

[0065] Further, see Figure 5 The clamping member 420 may also include a clamping part 422 and a third connecting part 423. The end of the clamping part 422 is connected to the third connecting part 423. The third connecting part 423 is connected to the side of the cover 410 near the support structure 200 through an elastic member 430. The clamping part 422 is provided with a welding hole 421. The side of the clamping part 422 near the cover 410 is provided with a groove 424. The cover 410 is provided with a through hole 411 at the position corresponding to the welding hole 421.

[0066] Specifically, the welding head of the welding device can sequentially pass through the through hole 411 and the welding hole 421 to weld the clamped workpiece 600. In one embodiment, when the welding device is a laser device, the through hole 411 and the welding hole 421 allow the laser to pass through to weld the workpiece 600.

[0067] It is understandable that by providing a groove 424 on the side of the clamping part 422 near the cover 410, the depth of the welding hole 421 can be reduced, which is beneficial for the exhaust of fumes generated during the welding process of the workpiece 600, and can also reduce the risk of collision between the welding head used to weld the workpiece 600 and the clamping part 420.

[0068] In one embodiment, in order to improve the stability of the connection between the pressing part 422 and the cover 410 through the third connecting part 423, the third connecting part 423 may be connected to both ends of the pressing part 422 respectively.

[0069] See Figure 2 The support structure 200 may include a support member 210, which supports the workpiece 600. A limiting member is provided on the support member 210 to limit the position of the workpiece 600.

[0070] Understandably, when the workpiece 600 is placed on the support structure 200, the limiting member can restrict the workpiece 600 to a predetermined position so as to ensure that the pressing member 420 can accurately press the workpiece 600 after the cover 410 of the pressing structure 400 is installed on the base 100.

[0071] In one embodiment, the limiting member further includes a first limiting part 220 and a second limiting part 230. The first limiting part 220 is disposed opposite to the support member 210 along the width direction of the support member 210, and the second limiting part 230 is disposed opposite to the support member 210 along the length direction of the support member 210. The first limiting part 220 and / or the second limiting part 230 are detachably connected to the support member 210.

[0072] It is understood that in the above method, the first limiting part 220 and the second limiting part 230 can cooperate to form a limiting space. When the workpiece 600 is loaded, the workpiece 600 can be loaded into the limiting space to achieve the positioning of the workpiece 600.

[0073] In addition, the first limiting part 220 and / or the second limiting part 230 are detachably connected to the support member 210, and the positions of the first limiting part 220 and the second limiting part 230 can be adjusted so that the limiting space formed by the first limiting part 220 and the second limiting part 230 can be compatible with workpieces 600 of different lengths and widths, thereby improving the compatibility of the welding fixture.

[0074] For example, multiple second adjustment holes 211 at different positions can be provided on the support member 210. By connecting the first limiting part 220 and / or the second limiting part 230 to the second adjustment holes 211 at different positions on the support member 210, the position of the limiting part and / or the second limiting part 230 on the support member 210 can be changed.

[0075] Furthermore, a clearance groove 212 may be provided on the support member 210 at the position corresponding to the placement of the workpiece 600, and the clearance groove 212 extends to the end of the support member 210.

[0076] Understandably, the clearance groove 212 facilitates the placement of the workpiece 600 on the support 210, and also facilitates the removal of the workpiece 600 from the support 210.

[0077] In one embodiment, a clearance groove 212 may be provided on the support member 210.

[0078] See Figure 1 and Figure 2 In one embodiment, the welding fixture may also include a latch 500, and the cover 410 may be detachably connected to the base 100 via the latch 500.

[0079] Specifically, the latch 500 may include a lock seat 510 and a latch seat 520. The lock seat 510 and the latch seat 520 are respectively disposed on the base 100 and the cover 410, so that the cover 410 and the base 100 can be detachably connected.

[0080] Preferably, the lock seat 510 is disposed on the base 100, and the lock tongue seat 520 is disposed on the cover 410, with the lock tongue buckle on the lock seat 510 fastening the lock tongue seat 520. It is understood that because the lock seat 510 is larger than the lock tongue seat 520, the lock seat 510 is disposed on the base 100, and the lock tongue seat 520 is disposed on the cover 410. When the cover 410 is placed on the base 100, the lock buckle 500 locks the cover 410 and the base 100 together, thereby increasing the clamping force of the clamping member 420 on the workpiece 600.

[0081] Of course, in one embodiment, when the base 100 includes the fixing member 110, the lock seat 510 may be disposed on the fixing member 110.

[0082] See Figure 2 and Figure 3 In one embodiment, the base 100 may be provided with one of a positioning pin and a positioning hole 412, and the cover 410 may be provided with the other of a positioning pin and a positioning hole 412. When the cover 410 is placed on the base 100, the positioning pin can be inserted into the positioning hole 412 to achieve the positioning of the cover 410 on the base 100.

[0083] For example, a locating pin can be provided on the top of the base 100, and a locating hole 412 can be provided on the cover 410. When the cover 410 covers the base 100, the locating pin can be inserted into the locating hole 412 to ensure the accurate relative position between the cover 410 and the base 100, thereby ensuring the accurate relative position between the clamping member 420 on the cover 410 and the clamping part 422 of the workpiece 600, and ensuring the clamping accuracy. The locating hole 412 can be a through hole 411, a countersunk hole, or a groove, etc.

[0084] Of course, in one embodiment, when the base 100 includes a fastener 110, the positioning pin may be disposed on the top of the fastener 110.

[0085] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
