[0006] It can be understood that the present application performs clamping operations on automobile parts by setting up a clamping mechanism, and the clamping gap formed by the clamping mechanisms; at the same time, by setting an adjustment plate and an adjustment rod, during the clamping process, the adjustment plate can be driven to move by the rotation of the adjustment rod, thereby further realizing the change of the clamping gap, so that the parts can be clamped more accurately and stably.

[0007] In one embodiment, the adjusting rod is configured as a first threaded rod, a threaded hole is provided on the adapter plate, one end of the adjusting rod passes through the threaded hole and is connected to the adjusting plate, and the first threaded rod is threadedly connected to the threaded hole.

[0008] It can be understood that the adjusting rod is configured as a first threaded rod, and a threaded hole is provided on the adapter plate, so that the adjusting rod can be threadedly connected to the adapter plate through the threaded hole, and the adjusting rod passes through the threaded hole provided on the adapter plate to be connected to the adjusting plate. After adjusting the position of the adapter plate according to the size of the automotive parts, the position of the adapter plate remains unchanged, and rotating the first threaded rod can drive the adjusting plate to move relative to the adapter plate, thereby further adjusting the degree of clamping of the welding fixture on the parts.

[0009] In one of the embodiments, the clamping mechanism further includes a guiding unit, and the guiding unit is used to guide the adjustment plate to move relative to the adapter plate.

[0010] It can be understood that by providing the guide unit, a guiding effect on the movement of the adjustment plate is achieved, making the movement of the adjustment plate more stable.

[0011] In one of the embodiments, the guide unit includes a guide rod, and a guide hole is formed on the adapter plate; one end of the guide rod is fixed to the adjustment plate, and the other end thereof passes through the guide hole.

[0012] In one embodiment, the number of the clamping mechanisms is set to four, the four clamping mechanisms are arranged at four different positions on the mounting plate, and the four clamping mechanisms surround the clamping gap.

[0013] It can be understood that clamping automobile parts by means of clamping mechanisms in four different directions can effectively improve the stability of clamping.

[0014] In one embodiment, the automobile component welding fixture further includes a lifting mechanism, which is installed between the base and the mounting plate and is used to drive the mounting plate to perform lifting movement in a vertical direction relative to the base.

[0015] It can be understood that the lifting mechanism can drive the mounting plate to perform lifting movement in the vertical direction relative to the base, so that the height of the clamping mechanism can be adjusted according to the height of different operators, thereby improving the comfort level and applicability to different groups during welding operations.

[0016] In one embodiment, the lifting mechanism includes a second threaded rod and a threaded sleeve, the second threaded rod is vertically fixed on the base, the threaded sleeve is threadedly connected to the second threaded rod, and the mounting plate is mounted on the threaded sleeve.

[0034] See also Figures 1 to 3 The present application provides a welding fixture 100, which is used for welding automobile parts. It is mainly used to stably clamp and fix automobile parts of different sizes to facilitate workers to perform welding operations and improve the efficiency of welding operations.

[0035] like Figure 1 As shown, the welding fixture 100 includes a base 10, a mounting plate 20 and a plurality of clamping mechanisms 30. The mounting plate 20 is mounted on the base 10 and is used to set a welding clamping workbench for automobile parts. The plurality of clamping mechanisms 30 are arranged on the mounting plate 20. The clamping mechanisms 30 can enclose to form a clamping gap 40, and the clamping gap 40 is used to clamp automobile parts. Each clamping mechanism 30 includes a pusher 31, an adapter plate 32, an adjustment plate 33 and an adjustment rod 34. The pusher 31 is mounted on the mounting plate 20. The adapter plate 32 is fixed to the pusher 31 and moves under the drive of the pusher 31. The adjustment plate 33 is movably mounted on the adapter plate 32 and can move with the adapter plate 32. The adjustment rod 34 is mounted on the adapter plate 32 and connected to the adjustment plate 33, and is used to drive the adjustment plate 33 to move relative to the adapter plate 32 to change the size of the clamping gap 40.

[0036] It should be explained that the welding fixture 100 has poor stability during the clamping operation, which leads to a decrease in welding accuracy caused by the shaking of automobile parts. In addition, since it cannot be adjusted for parts of different sizes during the operation, it needs to be disassembled and then installed again, which affects the welding operation efficiency of the parts. In the present application, the welding fixture 100 is provided with a clamping mechanism 30, and a clamping gap 40 formed by the clamping mechanism 30 is formed to clamp the automobile parts. When the pusher 31 moves to the relative position of the mounting plate 20, it can drive the adapter plate 32 to move in the same direction. At the same time, the adapter plate 32 drives the adjustment plate 33 to move closer to the center of the mounting plate 20, so that the center position of the multiple clamping mechanisms 30 is adjusted to the size of the object to be acted on, the object to be acted on is fixed, and the stability during the clamping operation is improved; at the same time, during the operation, by providing the adjustment plate 33 and the adjustment rod 34, during the clamping process, the adjustment plate 33 can be driven to move by the adjustment rod 34, thereby further changing the clamping gap 40, so that the parts can be clamped more accurately and stably.

[0037] In one embodiment, the pusher 31 may be a cylinder, an oil cylinder or a telescopic rod structure. In this embodiment, the pusher 31 is configured as a cylinder.

[0038] Further, a mounting seat 21 is provided on the mounting plate 20, and the pusher 31 is fixed on the mounting seat 21. Here, the number of the mounting seats 21 and the number of the clamping mechanisms 30 are arranged in a one-to-one correspondence.

[0039] In one embodiment, please continue to refer to Figure 1 The adjusting rod 34 is configured as a first threaded rod 341, a threaded hole 321 is provided on the adapter plate 32, one end of the adjusting rod 34 is provided with the threaded hole 321 and connected to the adjusting plate 33, and the first threaded rod 341 is threadedly connected to the threaded hole 321. It can be understood that the adjusting rod 34 can be threadedly connected to the adapter plate 32 through the threaded hole 321, and the adjusting rod 34 passes through the threaded hole 321 provided on the adapter plate 32 and is connected to the adjusting plate 33. After adjusting the position of the adapter plate 32 according to the size of the automotive parts, the position of the adapter plate 32 remains unchanged, and rotating the first threaded rod 341 can drive the adjusting plate 33 to move relative to the adapter plate 32, thereby further adjusting the clamping degree of the welding fixture 100 on the parts.

[0040] Furthermore, the clamping mechanism 30 further includes a guide unit 35, which is used to guide the adjustment plate 33 to move relative to the adapter plate 32. The guide unit 35 includes a guide rod 351, and a guide hole 352 is provided on the adapter plate 32; one end of the guide rod 351 is fixed to the adjustment plate 33, and the other end is provided with the guide hole 352. It can be understood that the guide rod 351 connects the adjustment plate 33 and the adapter plate 32 through the guide hole 352, and when the first threaded rod 341 drives the adjustment plate 33 to move relative to the adapter plate 32, the guide rod 351 can ensure that the movement of the adjustment plate 33 is more stable.

[0041] Preferably, the guide rods 351 and the guide holes 352 correspond one to one, and the number of the guide rods 351 and the guide holes 352 may be two, three or four to ensure the stability of the adjustment plate 33 during operation.

[0042] In this embodiment, three guide rods 351 and three guide holes 352 are respectively located at the triangles of the adapter plate to form a stable triangular layout to strengthen the stability of the movement of the adjustment plate 33 and the adapter plate 32.

[0043] like Figure 1 and Figure 3As shown, the number of the clamping mechanisms 30 is set to four, and the four clamping mechanisms 30 are arranged at four different positions on the mounting plate 20, and the four clamping mechanisms 30 are arranged to form a clamping gap 40. It can be understood that clamping the automobile parts by the clamping mechanisms 30 at four different positions can effectively improve the stability of the clamping. Of course, it is not limited to this, and the number of the clamping mechanisms 30 can be set to three, five, six, etc., and can be specifically designed according to actual needs.

[0044] Exemplarily, the four clamping mechanisms 30 are arranged in a rectangular array. Specifically, the mounting plate 20 is rectangular, and the four clamping mechanisms 30 are respectively located on the four sides of the rectangular mounting plate 20, thereby forming four different orientations. Alternatively, the four clamping mechanisms 30 are arranged one by one at the four corners of the rectangular mounting plate 20.

[0045] like Figure 2 As shown, the welding fixture 100 further includes a lifting mechanism 50, which is installed between the base 10 and the mounting plate 20, and is used to drive the mounting plate 20 to perform lifting motion in the vertical direction relative to the base 10. In this way, the lifting mechanism 50 can drive the mounting plate 20 to perform lifting motion in the vertical direction relative to the base 10, so that the height of the clamping mechanism 30 can be adjusted according to the height of different operators, thereby improving the comfort level during welding operations and the applicability to different groups of people.

[0046] Please continue to refer to Figure 2 The lifting mechanism 50 includes a second threaded rod 51 and a threaded sleeve 52. The second threaded rod 51 is vertically fixed on the base 10. The threaded sleeve 52 is threadedly connected to the second threaded rod 51, and the mounting plate 20 is mounted on the threaded sleeve 52. The mounting plate 20 is mounted on the threaded sleeve 52. When the threaded sleeve 52 and the second threaded rod 51 move relative to each other in the vertical direction, the mounting plate 20 can be driven to move vertically, thereby adjusting the working height of the welding fixture 100, which is convenient for operators to work.

[0047] Please continue to refer to Figure 2 The lifting mechanism 50 further includes a manual operating rod 53, which is fixed to the threaded sleeve 52 and is used to drive the threaded sleeve 52 to rotate relative to the second threaded rod 51. When the mounting plate 20 needs to be adjusted in the vertical direction, the threaded sleeve 52 can be driven to move vertically on the second threaded rod 51 by rotating the manual operating rod 53, thereby driving the adapter plate 32 to move vertically, thereby achieving the height adjustment of the clamping mechanism 30 in the vertical direction. Here, by setting the manual operating rod 53, the lifting configuration of the mounting plate 20 is in manual mode, and some electric control devices such as motors are omitted, making the structure simpler and the cost lower.

[0048] Preferably, the number of the manual operating levers 53 can be one or more, and can be adjusted according to the specific operation conditions of the automobile parts welding. In this embodiment, the number of the manual operating levers 53 is two.

[0049] Please continue to refer to Figure 1 and Figure 2 The automobile parts welding fixture 100 further includes a plurality of plug rods 60, and the mounting plate 20 is provided with a plurality of plug holes 22, and each plug rod 60 can be inserted into a corresponding plug hole 22 and connected to the base 10. In this way, when the automobile parts need to be clamped and welded, the plug rods 60 are correspondingly inserted into the plug holes 22 and connected to the base 10, thereby increasing the stability of the mounting plate 20, preventing the mounting plate from shaking during the clamping operation, resulting in improper welding of the parts, and improving the accuracy of welding assembly.

[0050] Furthermore, the base 10 is provided with slots 11 corresponding to the plug holes 22, and the plug rods 60 inserted into the plug holes 22 are correspondingly inserted into the slots 11. It can be understood that the provision of the slots 11 can make the plug rods 60 more firmly inserted and fixed, further ensuring the stability of the mounting plate during welding operations.

[0051] Preferably, the number of the plug-in rods 60 is configured to be four, and accordingly, the number of the plug-in holes 22 is also set to four; wherein, the four plug-in holes 22 are arranged at the four corners of the mounting plate 20, so that the plug-in rods 60 are also arranged at the four corners of the mounting plate 20, which can increase the stability of the mounting plate 20.

[0052] Of course, the present invention is not limited thereto, and the number of the plug-in rods 60 may also be three, five, or six.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several deformations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
