[0025] The following description, in conjunction with the accompanying drawings, describes a welding fixture for a battery holder according to an embodiment of the present invention.
[0026] Reference Figure 1The present invention aims to provide an embodiment of a welding fixture for a battery holder.
[0027] According to an embodiment of the present utility model, the battery bracket includes part 100, part 210 and part 3120. Part 100 is connected to part 210, and part 3120 is connected to part 100. Both part 100 and part 210 have a U-shaped structure.
[0028] A welding fixture for a battery bracket according to an embodiment of this utility model, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a support 130, a first clamping assembly 140, and a second clamping assembly 150. The support 130 has a first positioning part, a second positioning part connected to the first positioning part, and a third positioning part. The first positioning part is used to limit the position of part 100, the second positioning part is used to limit part 2 110 to the front side of part 100, and the third positioning part is used to limit part 3 120 to the left or right side of part 100. The first clamping assembly 140 and the first positioning part can clamp part 100, and the second clamping assembly 150 and the second positioning part can clamp part 2 110.
[0029] It should be noted that the first clamping assembly 140 is a manual quick clamping device. The first clamping assembly 140 includes a cylinder 240 and a pressure block 250. The movable end of the cylinder 240 is connected to the pressure block 250, and the pressure block 250 is used to abut against part 2 110.
[0030] It is understood that this utility model, by setting a support 130, a first clamping assembly 140, and a second clamping assembly 150, provides a first positioning part, a second positioning part, and a third positioning part on the support 130. Part 100 is placed on the first positioning part, part 210 is placed on the second positioning part, and part 3120 is placed on the third positioning part. Then, the first clamping assembly 140 clamps and fixes part 100 to the first positioning part, and the second clamping assembly 150 clamps and fixes part 210 to the second positioning part. Thus, three parts can be clamped without having to clamp multiple parts in steps. This solves the problem of deformation caused by step welding of multiple thin stamped sheet metal parts, reduces the occurrence of welding defects, and improves welding efficiency.
[0031] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2The support 130 has a first plate 160, two first side plates 170 and a second side plate 180. The left and right sides of the first plate 160 are respectively connected to the tops of the two first side plates 170, and the left and right sides of the second side plate 180 are respectively connected to the front sides of the two first side plates 170. The top of the first plate 160 and the opposite sides of the two first side plates 170 form a first positioning part, and the front side of the second side plate 180 and the opposite sides of the two first side plates 170 form a second positioning part.
[0032] It is understandable that by setting a first plate 160, two first side plates 170 and a second side plate 180, a first positioning part is formed on the first plate 160 and the two first side plates 170, and a second positioning part is formed on the second side plate 180 and the two first side plates 170. The structure of the first plate 160, the two first side plates 170 and the second side plate 180 is simple, which reduces the manufacturing cost of the first positioning part and the second positioning part and simplifies the structure of the fixture.
[0033] In some embodiments of this utility model, the support 130 has a first plate 160, and the top of the first plate 160 is provided with a plurality of positioning pins 190. The positioning pins 190 cooperate with the positioning holes of the part 100 to position the part 100.
[0034] Understandably, the precise fit between the locating pin 190 and the locating hole of part 100 eliminates the possibility of in-plane movement and rotation of part 100 during clamping and welding, making it particularly suitable for the precise fixing of thin sheet metal parts.
[0035] In some embodiments of this utility model, the support 130 has a first side plate 170, the first side plate 170 is provided with a support member 200, and a first positioning groove 210 is provided between the support member 200 and the first side plate 170. The first positioning groove 210 matches the shape of the part 3 120 and can accommodate the part 3 120.
[0036] It is understandable that the shape of the first positioning groove 210 matches that of part three 120. By placing part three 120 into the first positioning groove 210 of the support 200, the positioning of part three 120 can be achieved without additional adjustment, which greatly shortens the clamping time and ensures its relative positional relationship with part one 100.
[0037] In some embodiments of this utility model, the side of part three 120 away from the support member 200 can abut against the end of part one 100.
[0038] It is understandable that by having part 2 110 abut against the end of part 1 100, the geometric features of the parts themselves are used for mutual positioning, which enhances the overall structural rigidity and further reduces welding deformation or edge warping of part 1 100.
[0039] In some embodiments of this utility model, the support 130 has a second side plate 180, and a support plate 220 is provided below the second side plate 180. The two adjacent planes of the second side plate 180 and the support plate 220 are vertically distributed and can limit the position of the second part 110.
[0040] Understandably, the two adjacent vertical planes formed by the second side plate 180 and the support plate 220 provide a positioning reference for part 2 110, ensuring the positional dimensional requirements between part 2 110 and part 1 100.
[0041] In some embodiments of this utility model, the support plate 220 is provided with a second positioning groove 230, which is used to accommodate the folded ear of part 2 110.
[0042] Understandably, the second positioning groove 230 is specifically designed to accommodate the folded lug of part 2 110, so that part 2 110 can be positioned in the second positioning part, enabling the second positioning part to accurately position part 2 110.
[0043] In some embodiments of this utility model, reference is made to Figure 2 The first positioning part has a first plane 260, a second plane 270 and a third plane 280 respectively connected to the left and right sides of the first plane 260. The first plane 260 is perpendicular to the second plane 270 and the third plane 280 respectively. The part 100 can fit against the first plane 260, the second plane 270 and the third plane 280 respectively along the inner direction of the wall thickness.
[0044] Understandably, the first plane 260, the second plane 270, and the third plane 280 constrain the degrees of freedom of part 100 from three directions and fit against the sidewall in the thickness direction of part 100, increasing the contact area between the first positioning part and part 100 and increasing the area of the first positioning part supporting part 100. Combined with the positive pressure of the first clamping assembly 140, this provides a stable foundation for welding and reduces the occurrence of deformation or edge lifting during welding of part 100.
[0045] In some embodiments of this utility model, the second positioning part has a fourth plane 290, and the second part 110 can be fitted with the fourth plane 290 and the first part 100 respectively along the inner direction of the wall thickness.
[0046] Understandably, the fourth plane 290 serves as the sidewall of part 2 110 in the thickness direction, increasing the contact area between the second positioning part and part 2 110, increasing the area of the second positioning part supporting part 2 110, and the second clamping assembly 150 drives part 2 110 to fit tightly against the plane and part 1 100, reducing the deformation that occurs when part 2 110 is welded.
[0047] In some embodiments of this utility model, the first positioning part has a first plane 260, and the first clamping assembly 140 and the first plane 260 are capable of clamping part 100. The second positioning part has a fourth plane 290, and the second clamping assembly 150 and the fourth plane 290 are capable of clamping part 210. The clamping directions of the first clamping assembly 140 and the second clamping assembly 150 are set at an angle.
[0048] It is understood that the first clamping assembly 140 and the second clamping assembly 150 act on the thickness direction of the plate respectively. The first clamping assembly 140 and the second clamping assembly 150 cooperate with the first plane 260 and the fourth plane 290 respectively to clamp the corresponding parts, ensuring the effective application of clamping force and avoiding positioning deviation or workpiece warping caused by incorrect clamping direction.
[0049] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
