Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts welding equipment technology, and in particular to a welding fixture and welding equipment. Background Technology
[0002] During the piercing welding process of the inner and outer fenders of the new A66, due to the special structure and materials of the fenders, there are many welding positions required. Furthermore, due to the characteristics of the materials (soft rubber for the outer panel and hard rubber for the inner panel), deformation or misalignment of the inner and outer panels is prone to occur during the welding process. Previous jigs cannot be adapted to the inner and outer panels of this new A66 fender, making automated welding impossible. Currently, welding is done manually, but the weld marks from manual welding are inconsistent and prone to burn-through or incomplete welding. Utility Model Content
[0003] This application aims to solve one of the aforementioned technical problems in the prior art. Therefore, embodiments of this application provide a welding fixture.
[0004] This application also provides a welding device.
[0005] According to an embodiment of the first aspect of this application, a welding fixture is provided, including a mounting member; at least one set of positioning members disposed on the mounting member, the positioning members having positioning grooves for positioning fender products; at least one set of pre-tightening members disposed on the mounting member and close to the positioning grooves, the pre-tightening members providing pre-pressure acting on the side of the fender product located in the positioning grooves, so that the other side of the fender product fits against the groove wall of the positioning grooves; and a clamping member rotatably disposed on the mounting member, the clamping member including a plurality of clamping elements adjustable in position, the clamping member pressing against the fender product when flipped above the positioning grooves.
[0006] The aforementioned welding fixture has at least the following beneficial effects: The fender product is positioned using the positioning groove of the positioning component. After the fender is placed, the pre-tightening component activates and applies a certain pre-pressure to one side of the fender product, causing the other side of the fender product to move until it fits against the groove wall of the positioning groove, thus completing the positioning. Then, the clamping position of the clamping component is adjusted to prevent the clamping position from affecting the welding. The clamping component is then flipped so that it can clamp the areas of the fender product that do not require welding, ensuring effective fit between the inner and outer panels of the fender product. During automated welding, the welding fixture of this application is placed in the welding equipment, and the automatic welding head of the welding equipment sequentially welds the areas of the fender product to be welded, effectively improving the positioning speed of the fender product and preventing incomplete welding due to insufficient clamping. Because multiple clamping components are arranged, it prevents some welded areas of the fender product from lifting, which would affect the welding quality.

The connecting member is disposed on the flipping frame through a first adjustment structure so that the position of the connecting member can be adjusted along a first direction. The clamping member is disposed on the connecting member through a second adjustment structure so that the clamping member can be adjusted along a second direction and a third direction. The first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the third direction.
[0013] According to the welding fixture of the first aspect of this application, the first adjustment structure includes a first screw and a first oblong hole. The first oblong hole is disposed on the connector and disposed along the first direction.

[0027] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0028] Figure 1 This is a schematic diagram of the structure of the fender product 100 after welding according to an embodiment of this application. The fender product 100 has multiple welding points 101 on its inner side. The fender product 100 includes an inner plate and an outer plate. The outer plate has higher hardness and can resist deformation, while the inner plate is softer and easily deformed. In order to avoid false welding and welding errors during the automatic welding process, this embodiment of the application provides a welding fixture.
[0029] like Figures 1 to 5 As shown, the welding fixture includes a mounting component 201, at least one set of positioning components 210, at least one set of pre-tightening components 220, and a clamping component 300. The mounting component 201 serves as the mounting base for the other components, and the positioning components 210, pre-tightening components 220, and clamping components 300 are all disposed on the mounting component 201.
[0030] The positioning member 210 is provided with a positioning groove for positioning the fender product 100. The positioning groove is used to position the fender product 100. The pre-tightening member 220 is located close to the positioning groove. The pre-pressure provided by the pre-tightening member 220 acts on the side of the fender product 100 located in the positioning groove, so that the other side of the fender product 100 can fit against the groove wall of the positioning groove, thereby completing the side and bottom positioning of the fender product 100.
[0031] The clamping member 300 is rotatably mounted on the mounting member 201. The clamping member 300 includes several clamping members 330 that can be adjusted in position. When the clamping member 300 is flipped over to the position groove, the clamping members 330 press against the fender product 100, thereby completing the top clamping and limiting of the fender product 100 and preventing misalignment or movement of the inner and outer plates during the welding process.
[0032] The welding fixture of this application positions the fender product 100 through the positioning groove of the positioning member 210. After the fender is placed, the pre-tightening member 220 is activated and applies a certain pre-pressure to one side of the fender product 100, so that the other side of the fender product 100 moves to fit against the groove wall of the positioning groove to complete the positioning. Then, the clamping position of the clamping member 330 of the clamping member 300 is adjusted to avoid the setting position of the clamping member 330 affecting the welding. Then, the clamping member 300 is flipped so that the clamping member 330 can clamp the part of the fender product 100 that does not need to be welded, so that the welding position of the inner and outer panels of the fender product 100 can be effectively fitted.
[0033] When performing automated welding, the welding fixture of this application is placed on the welding equipment, and the welding head of the welding equipment is used to weld the positions to be welded on the fender product 100 in sequence, which effectively improves the positioning speed of the fender product 100 and can also avoid the situation of incomplete welding caused by insufficient clamping. Since multiple clamping parts 330 are arranged, it can prevent the welding positions of the fender product 100 from lifting up and affecting the welding quality.
[0034] In some embodiments, such as Figure 3 As shown, the positioning component 210 includes several positioning blocks 211. The top surface of the several positioning blocks 211 forms the bottom of the positioning groove. Some of the positioning blocks 211 that are far away from the pre-tightening component 220 are provided with protrusions 212. All the protrusions 212 surround one side of the positioning groove. In this embodiment, the other side of the positioning groove has no groove wall.
[0035] Specifically, the top surface of the positioning block 211 is provided with a contoured surface that can fit into the corresponding position of the fender product 100 to ensure that the welding positions of the fender product 100 can be effectively supported. Compared with setting a contoured surface on a whole plate, the contoured surface formed by several positioning blocks 211 saves more materials and is easier to process. It can also further improve the positioning accuracy and avoid the situation of incomplete welding of the fender product 100 due to insufficient support.
[0036] In some embodiments, the positioning block 211 is elastic, which buffers the welding process and prevents scratches on the fender product 100, thus ensuring the welding yield of the product.
[0037] In the embodiments shown in this application, the positioning block 211 may be made of soft foam.
[0038] In some other embodiments, the positioning member 210 also includes a proximity sensor 240 and a pressure sensor. The proximity sensor 240 is used to sense the presence or absence of the fender product 100 on the positioning groove to prevent welding from being performed without placing the product. The pressure sensor is installed inside the soft foam to detect whether the welding head is pressing too hard on the product during the welding process, so as to avoid weld burn-through and also to prevent the clamping force of the clamping member 300 from being too large, which would cause product deformation and affect the quality of the welded product.
[0039] In some examples, the pre-tightening component 220 includes several clamping cylinders, with the cylinder rods of the clamping cylinders facing the protrusion 212. The ends of the cylinder rods are provided with elastic buffers to prevent product deformation during the pre-tightening process from affecting welding accuracy.
[0040] In some embodiments, such as Figure 4 As shown, the clamping member 300 includes a flipping frame 310 and a connecting member 320. One side of the flipping frame 310 is rotatably mounted on the mounting member 201. The number of connecting members 320 is the same as the number of clamping members 330. The connecting member 320 is mounted on the flipping frame 310 through a first adjustment structure so that the position of the connecting member 320 can be adjusted along a first direction. The clamping member 330 is mounted on the connecting member 320 through a second adjustment structure so that the clamping member 330 can be adjusted along a second direction and a third direction. The first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the third direction.
[0041] The first and second adjustment structures make the adjustment of the clamping component 330 more flexible and convenient. When clamping and welding other products, the positioning block 211 can be replaced, and then the adjustment can be made according to the clamping point to adapt to the clamping and fixing of different products.
[0042] In some specific embodiments, the first adjustment structure includes a first screw and a first oblong hole 321. The first oblong hole 321 is disposed on the connector 320 and is arranged along a first direction. The first screw passes through the first oblong hole 321 and is threadedly connected to the flipping frame 310, thereby locking the connector 320 to the flipping frame 310. The cooperation between the screw and the oblong hole makes the adjustment of the connector 320 more convenient. Specifically, when adjustment is required, the restriction of the first screw is loosened, and the connector 320 is adjusted along the first direction to realize the translation of the clamping member 330. After the position is adjusted, the first screw is tightened again.
[0043] It should be noted that when the tilting frame 310 rotates to the top of the positioning slot, the first and second directions are both horizontal, and the third direction is vertical.
[0044] In some specific embodiments, the second adjustment structure includes a second oblong hole 322 and a nut. The second oblong hole 322 is disposed on the connector 320 and arranged along the second direction. The clamping member 330 is provided with a stud adapted to the nut. The stud passes through the second oblong hole 322, and two nuts are disposed on the stud, with the two nuts respectively located on both sides of the connector 320. Through the cooperation of the stud, nuts, and oblong hole, the clamping member 330 can be adjusted in both the horizontal and vertical directions.
[0045] In some embodiments, to prevent the clamping member 330 from damaging or scratching the product, a buffer portion can be provided at the clamping end of the clamping member 330. The buffer portion can be made of rubber material so as to provide a certain buffering effect.
[0046] In some embodiments, the welding fixture further includes a limiting block 230, which is used to limit the flipping position of the flipping frame 310. The flipping frame 310 is provided with a limiting part 340 that abuts against the limiting block 230. The cooperation between the limiting block 230 and the limiting part 340 prevents the product from being over-pressed, which would cause deformation and affect the quality of the finished product.
[0047] In the embodiment shown in this application, two sets of positioning members 210 are provided, and two sets of corresponding pre-tightening members 220 are also provided. The clamping member 300 can simultaneously clamp the fender product 100 on both sets of positioning members 210. The above design can effectively improve production efficiency and enable the welding of two products at a time.
[0048] In addition, this application embodiment also provides a welding device, including the welding fixture described above.
[0049] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application 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 this application.
