[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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.

[0027] 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 with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] The following is combined with Figures 1 to 6 This invention describes a welding fixture for automotive parts.

[0029] like Figures 1 to 6 As shown, this utility model provides a welding fixture for automotive parts, including a fixture base 1, a first clamping mechanism 2, a second clamping mechanism 3, a third clamping mechanism 4, and a limiting member 5. The first clamping mechanism 2 is located on one side of the fixture base 1, the second clamping mechanism 3 is located on the other side of the fixture base 1, and the third clamping mechanism 4 is located on the fixture base 1, between the first clamping mechanism 2 and the second clamping mechanism 3. The third clamping mechanism 4 is inclined. Both the first clamping mechanism 2 and the second clamping mechanism 3 are provided with limiting members 5.

[0030] For ease of explanation, in this embodiment, each orientation is as follows: Figure 1 As shown.

[0031] Specifically, the first clamping mechanism 2 is located on the left side of the clamp base 1, the second clamping mechanism 3 is located on the right side of the clamp base 1, and the third clamping mechanism 4 is located in the middle of the clamp base 1. The third clamping mechanism 4 is inclined.

[0032] Furthermore, the first clamping mechanism 2 includes a first cylinder 21 and a first clamping arm 22. The first cylinder 21 is connected to the first clamping arm 22 to drive the first clamping arm 22 to press against the workpiece 6. The first cylinder 21 is fixedly connected to the fixture base 1. The first cylinder 21 drives the first clamping arm 22 to rotate toward the third clamping mechanism 4, thereby pressing the workpiece 6.

[0033] Furthermore, the second clamping mechanism 3 includes a second cylinder 31 and a second clamping arm 32. The second cylinder 31 is connected to the second clamping arm 32 to drive the second clamping arm 32 to press against the workpiece 6. The second cylinder 31 is fixedly connected to the fixture base 1. The second cylinder 31 drives the second clamping arm 32 to rotate toward the third clamping mechanism 4, thereby pressing the workpiece 6.

[0034] In the automotive parts welding fixture provided in this embodiment, the first clamping mechanism 2, the second clamping mechanism 3, the third clamping mechanism 4, and the limiting member 5 work together to form a working space for clamping the workpiece 6. This space can support the middle part of the long strip-shaped workpiece 6 with a bending angle and clamp both ends of the workpiece 6, improving the stability and accuracy of clamping. The third clamping mechanism 4 is inclined and can provide clamping force to the workpiece 6 with a bending angle, while also providing support and positioning clamping to ensure the stability of the workpiece 6 during the welding process, thereby improving the welding quality.

[0035] In some embodiments, the first clamping mechanism 2 further includes a first support base 23 and a first positioning pin 24. The first support base 23 is disposed on the fixture base 1, the first cylinder 21 is disposed on the first support base 23, and the first positioning pin 24 is disposed on the first support base 23. Specifically, the first cylinder 21 is a swing cylinder. The first cylinder 21 can drive the first clamping arm 22 to rotate toward the third clamping mechanism 4, thereby pressing the workpiece 6. Since most automotive parts have mounting holes for installation at their ends, by setting the first positioning pin 24 and inserting the first positioning pin 24 into the mounting hole of the workpiece 6, the workpiece 6 can be better positioned and clamped, ensuring the stability of the workpiece 6 during the welding process, thereby improving the welding quality.

[0036] In some embodiments, the second clamping mechanism 3 further includes a second support base 33 and a second positioning pin 34. The second support base 33 is disposed on the fixture base 1, the second cylinder 31 is disposed on the second support base 33, and the second positioning pin 34 is disposed on the second clamping arm 32. Specifically, the second cylinder 31 is a swing cylinder. The second cylinder 31 can drive the second clamping arm 32 to rotate toward the third clamping mechanism 4, thereby pressing the workpiece 6. Since most automotive parts have mounting holes for installation at their ends, by setting the second positioning pin 34 and inserting the second positioning pin 34 into the mounting hole of the workpiece 6, the workpiece 6 can be better positioned and clamped, ensuring the stability of the workpiece 6 during the welding process, thereby improving the welding quality.

[0037] In some embodiments, the third clamping mechanism 4 includes a third cylinder 41, a third clamping arm 42, and a third support base 43. The third support base 43 is disposed on the fixture base 1, and the third cylinder 41 is disposed on the third support base 43. The third cylinder 41 is connected to the third clamping arm 42 to drive the third clamping arm 42 to move toward the workpiece 6. The lower side of the first clamping arm 22, the lower side of the second clamping arm 32, and the upper side of the third clamping arm 42 together form a working space for clamping the workpiece 6. Specifically, the third cylinder 41 is a linear cylinder. The third cylinder 41 drives the third clamping arm 42 to move toward the workpiece 6, thereby clamping the workpiece 6 together with the first clamping arm 22 and the second clamping arm 32. This can better position and clamp the workpiece 6, ensure the stability of the workpiece 6 during the welding process, and thus improve the welding quality.

[0038] In some embodiments, the third clamping mechanism 4 further includes a jaw assembly 44, which includes a clamping jaw 441, a jaw cylinder 442, a jaw support 443, and a jaw connecting rod 444. The jaw support 443 is disposed on the third support 43, and the jaw cylinder 442 is disposed on the jaw support 443. The clamping jaw 441 is rotatably connected to the jaw support 443. The movable end of the jaw cylinder 442 is connected to the clamping jaw 441 through the jaw connecting rod 444. Specifically, most automotive parts have mounting holes at their ends. The jaw cylinder 442 drives the jaw connecting rod 444 to rotate the clamping jaw 441, thereby enabling it to clamp onto the end of the workpiece 6. This allows for better positioning and clamping of the workpiece 6, ensuring the stability of the workpiece 6 during the welding process and thus improving the welding quality.

[0039] In some embodiments, the third support base 43 is provided with claw assemblies 44 on both sides, which improves the clamping and positioning effects.

[0040] In some embodiments, the automotive parts welding fixture also includes a leak-proof sensor, which is located on the third support 43. The leak-proof sensor is used to detect whether there is a workpiece 6 in the workspace, thus achieving a higher degree of automation.

[0041] In some embodiments, the leak-proof sensor is a distance sensor, which provides better detection performance.

[0042] In some embodiments, the limiting member 5 is U-shaped, which can better clamp the workpiece 6, ensure the stability of the workpiece 6 during the welding process, and thus improve the welding quality.

[0043] In some embodiments, both the first cylinder and the second cylinder are clamping cylinders, such as TUNKERS cylinders.

[0044] In some embodiments, the third cylinder is a linear cylinder.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
