[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0026] Example 1
[0027] like Figure 1 — Figure 6 As shown, the welding fixture for a door pillar cover of this utility model includes a base 100, a first upright plate 110, a second upright plate 120, a connecting seat 200, a first positioning component 300, and a second positioning component 400.
[0028] The base 100 has a first upright plate 110 and a second upright plate 120, which are connected by a connecting seat 200, which is connected to the base 100. A first positioning member 300 is movably mounted on the first upright plate 110 and is connected to the connecting seat 200 by a first hinge 230. The first positioning member can rotate relative to the connecting seat. A second positioning member 400 is movably mounted on the second upright plate 120 and is connected to the connecting seat by a second hinge 240. The second positioning member can rotate relative to the connecting seat. The connecting seat 200 is located between the first positioning member 300 and the second positioning member 400, and is positioned relative to the door pillar cover 500. During welding, the angles between the first positioning member 300 and the base 100, as well as the angle between the second positioning member 400 and the base 100, need to be adjusted according to the shape of the doorpost cover 500. This ensures that the shape formed by the first positioning member 300, the connecting seat, and the second positioning member 400 fits the bottom surface of the doorpost cover 500. After that, the doorpost cover 500 needs to be placed on the top surface of the first positioning member 300, the connecting seat, and the second positioning member 400. This not only allows for stable welding of the doorpost cover 500, but also makes the welding fixture adaptable to doorpost covers 500 of different specifications. After welding is completed, the doorpost cover 500 can be removed from the welding fixture, thus completing the welding work of the doorpost cover 500.
[0029] The connecting seat 200 includes a pair of third vertical plates 210 disposed on the base 100, and the tops of the two third vertical plates 210 are connected by a connecting plate 220.
[0030] The first positioning component 300 includes a pair of first vertical plates 310. The tops of the two first vertical plates 310 are connected by a first base plate 320. The first base plate 320 is connected to the connecting plate by the aforementioned first hinge. There are two first upright plates 110, with the two first vertical plates 310 located between the two first upright plates 110. The two first vertical plates 310 are respectively attached to the adjacent first upright plate 110. The first vertical plates 310 are provided with a plurality of first mounting holes 311, and the first upright plates 110 are provided with first waist holes 1 corresponding to the first mounting holes 311. 11. The first mounting hole 311 and the first waist hole 111 are connected by the first bolt 340. When the angle of the first positioning member 300 needs to be changed, the first bolt 340 needs to be loosened first. When a force is applied to the end of the first base plate 320 away from the connecting seat 200, the first base plate 320 will rotate around the first hinge. In this way, the angle between the first base plate 320 and the base 100 can be adjusted so that the top surface of the first base plate 320 can be attached to the bottom surface of the door pillar cover 500. That is, the first base plate 320 and the connecting plate can be aligned. The angle between 220 and 220 can match the bending angle of the door pillar cover 500 at the bend before welding. Then, all the first bolts 340 are tightened. Furthermore, when the first base plate 320 and the first vertical plate 310 are adjusted relative to the connecting plate 220 or the base 100, because the width of the first waist hole 111 is greater than the diameter of the first mounting hole 311, and the diameter of the first bolt 340 is the same as the diameter of the first mounting hole 311, the first mounting hole 311 is always aligned with the first waist hole 111, so that the first waist hole 111 will not restrict the first bolt. When bolt 340 moves, the angle between the first vertical plate 310 and the first base plate 320 can be adjusted smoothly. After the angle is adjusted smoothly, since the head diameter of the first bolt 340 is larger than the width of the first waist hole 111, the first bolt 340 is threadedly connected to the first mounting hole 311. Thus, after the first bolt 340 is tightened, the friction between the first vertical plate 110 and the first vertical plate 310 can be increased smoothly, thereby restricting the movement of the first vertical plate 310 relative to the first vertical plate 110 and ensuring that the first base plate 320 can stably support the door pillar cover 500.
[0031] The second positioning component 400 includes a pair of second vertical plates 410. The tops of the two second vertical plates 410 are connected by a second base plate 420. The second base plate 420 is connected to the connecting plate via the aforementioned second hinge. There are two second vertical plates 120, with the two second vertical plates 410 located between the two second vertical plates 120. The two second vertical plates 410 are respectively attached to the adjacent second vertical plate 120. The second vertical plates 410 are provided with a plurality of second mounting holes 411, and the second vertical plates 120 are provided with second waist holes 121 corresponding to the second mounting holes 411. The second mounting hole 411 and the second waist hole 121 are connected by the second bolt 440. When the angle of the second positioning member 400 needs to be changed, all the second bolts 440 must be loosened first. When a force is applied to the end of the second base plate 420 away from the connecting seat 200, the second base plate 420 will rotate around the second hinge. In this way, the angle between the second base plate 420 and the base 100 can be adjusted so that the top surface of the second base plate 420 can be attached to the bottom surface of the door pillar cover 500. That is, the second base plate 420 and the connecting plate can be aligned. The angle between 220 and 220 can match the bending angle of the door pillar cover 500 at the bend before welding. Then, all the second bolts 440 are tightened. Furthermore, when the second base plate 420 and the second vertical plate 410 are angled relative to the connecting plate 220 or the base 100, because the width of the second waist hole 121 is greater than the diameter of the second mounting hole 411, and the diameter of the second bolt 440 is the same as the diameter of the second mounting hole 411, the second mounting hole 411 is always aligned with the second waist hole 121, thus ensuring that the second waist hole 121 does not restrict the second... The movement of the two bolts 440 allows the second vertical plate 410 and the second base plate 420 to be adjusted at an angle. After the angle is adjusted, since the diameter of the head of the second bolt 440 is larger than the width of the second waist hole 121, the second bolt 440 is threaded into the second mounting hole 411. Thus, after tightening the second bolt 440, the friction between the second vertical plate 120 and the second vertical plate 410 can be increased, thereby restricting the movement of the second vertical plate 410 relative to the second vertical plate 120 and ensuring that the second base plate 420 can stably support the door pillar cover 500.
[0032] In this utility model, side plates 510 are provided on both sides of the door pillar cover 500.
[0033] First base plate 320 has first enclosure plates 330 on both sides, and second base plate 420 has second enclosure plates 430 on both sides. Multiple quick clamps (not shown in the figure) are installed on both the first base plate 320 and the second base plate 420. After the door pillar cover 500 is positioned on the welding fixture, one of the side plates 510 of the door pillar cover 500 needs to abut against the adjacent first enclosure plate 330 and second enclosure plate 430. The first enclosure plate 330 and the side plate 510, and the second enclosure plate 430 and the side plate 510 are fixed by F clamps (not shown in the figure). Then, the middle part of the door pillar cover 500 is pressed onto the first base plate 320 and the second base plate 420 by multiple quick clamps to prevent the door pillar cover 500 from shifting during the welding process.
[0034] When placing the door pillar cover 500, it is necessary to ensure that the edge of one end of the door pillar cover 500 is flush with the end of the first base plate 320 away from the connecting plate 220, and to ensure that the edge of the other end of the door pillar cover 500 is flush with the end of the second base plate 420 away from the connecting plate 220, so as to position the door pillar cover 500 on the welding fixture.
[0035] A first lifting rod 130 for pushing the first positioning member 300 upward is movably mounted on the base 100, wherein the position of the first lifting rod in contact with the first base plate is located at the end of the first base plate away from the connecting plate. A second lifting rod 140 for pushing the second positioning member 400 upward is also movably mounted on the base 100, wherein the position of the second lifting rod in contact with the second base plate is located at the end of the second base plate away from the connecting plate. The top end of the first lifting rod 130 and the first base plate 320, as well as the top end of the second lifting rod 140 and the second base plate 420, are in contact connection. Specifically, a first cylinder for driving the first lifting rod 130 to move up and down is provided at the bottom of the base 100. (Not shown in the figure) At the bottom of the base 100, there is also a second cylinder (not shown in the figure) for driving the second lifting rod 140 to move up and down. By controlling the tooling of the first cylinder and the second cylinder, the first lifting rod 130 and the second lifting rod 140 can be driven to rise and fall relative to the base 100, thereby pushing the first base plate 320 and the second base plate 420 to rise relative to the base 100. When the bottom of the first base plate 320 is not supported by the first lifting rod 130, the first positioning member 300 will automatically flip downward under its own weight. Similarly, when the bottom of the second base plate is not supported by the second lifting rod, the second positioning member will automatically flip downward under its own weight.
[0036] Example 2
[0037] The difference between this embodiment and Embodiment 1 is that the first cylinder and the second cylinder are omitted in this embodiment, and the structure of the first lifting rod 130 and the second lifting rod 140 is changed.
[0038] Specifically, the surfaces of the first lifting rod 130 and the second lifting rod 140 are threaded. By turning the first lifting rod 130 and the second lifting rod 140, the first lifting rod 130 and the second lifting rod 140 can be raised or lowered relative to the base 100, thereby pushing the first base plate 320 and the second base plate 420 to rise relative to the base 100.
[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0040] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0042] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
