[0026] Example 1

[0027] like Figures 1 to 2 As shown, a fixture structure for processing automobile sheet metal parts includes a base 1 and a workbench 2. A rotating mechanism 3 is installed on the base 1, and the rotating mechanism 3 is connected to the workbench 2 to drive the workbench 2 to rotate; lifting mechanisms 4 are fixed on both sides of the workbench 2, and a clamping assembly 6 is connected between the telescopic ends of the two lifting mechanisms 4. The clamping assembly 6 has a first clamping plate 61 and a second clamping plate 62 that are arranged opposite to each other. A driving mechanism 7 is fixed to the telescopic end of the lifting mechanism 4, and the driving mechanism 7 is connected to the first clamping plate 61 or\ and the second clamping plate 62 to drive the first clamping plate 61 and the second clamping plate 62 to move toward or away from each other.

[0028] In this embodiment, the fixture structure for processing automobile sheet metal parts places the sheet metal part between the first clamping plate 61 and the second clamping plate 62, and starts the driving mechanism 7 to drive the first clamping plate 61 and / or the second clamping plate 62 to move toward each other to fix the sheet metal part. Since the clamping space of the first clamping plate 61 and the second clamping plate 62 can be adjusted by the driving mechanism 7, it is possible to fix and clamp sheet metal parts of different models; starting the rotating mechanism 3 can drive the workbench 2 to rotate, prompting the lifting mechanism 4 and the clamping assembly 6 located on the workbench 2 to rotate, thereby realizing the angle adjustment of the sheet metal part; the lifting mechanism 4 drives the adjustment of the height of the clamping assembly 6, thereby realizing the adjustment of the height of the sheet metal part.

[0029] It should be noted that the lifting mechanism 4 can be an electric telescopic device, or a pneumatic or hydraulic telescopic device, and other structures that can achieve lifting motion are also within the protection scope of the present utility model.

[0030] like Figures 1 to 3 As shown, the clamping assembly 6 also includes a mounting frame 63 and a sliding rod 65. The mounting frame 63 is mounted on the telescopic ends of the two lifting mechanisms 4. The first clamping plate 61 is fixedly mounted on one side of the inner wall of the mounting frame 63. The mounting frame 63 is provided with long holes 66 on both sides along the movement direction of the driving mechanism 7. The two ends of the sliding rod 65 are respectively located in the long holes 66 and are slidably connected to the long holes 66. The second clamping plate 62 is mounted on the sliding rod 65 and located in the mounting frame 63. The second clamping plate 62 is connected to the driving mechanism 7. In this embodiment, the movement direction of the driving mechanism 7 is consistent with the length direction of the mounting frame 63. The length direction of the long hole 66 is consistent with the movement direction of the driving mechanism 7. The long hole 66 is provided in the length direction of the mounting frame 63. The two ends of the sliding rod 65 are mounted in the long hole 66. When the driving mechanism 7 pushes the second clamping plate 62 to move, the long hole 66 can limit the movement direction of the sliding rod 65, ensuring that the sliding rod 65 can move in the direction of the opening of the long hole 66.

[0031] like Figure 2 、 Figure 3 As shown, a U-shaped connecting rod 64 is fixed to both sides of the mounting frame 63 along the direction of movement of the drive mechanism 7. A groove 67 is formed at each end of the sliding rod 65. The connecting rod 64 is received in the groove 67 and slidably connected thereto. In this embodiment, since both ends of the sliding rod 65 extend out of the elongated hole 66 of the mounting frame 63 and the grooves 67 are provided at both ends of the sliding rod 65, the connecting rod 64 is located in the groove 67. When the drive mechanism 7 drives the second clamping plate 62 toward the first clamping plate 61, the sliding rod 65 is prevented from rolling, further ensuring the stability of the movement of the sliding rod 65.

[0032] like Figure 3As shown, a stabilizing plate 68 is fixed to the outer surface of the connecting rod 64, and a return spring 69 is fixed between the sliding rod 65 and the stabilizing plate 68 and located on the outer side of the connecting rod 64. In this embodiment, one end of the return spring 69 abuts against the sliding rod 65, and the other end of the return spring 69 abuts against the stabilizing plate 68. When the driving mechanism 7 drives the second clamping plate 62 to move toward the first clamping plate 61, the sliding rod 65 squeezes the return spring 69, causing the return spring 69 to generate a compression deformation. When the driving mechanism 7 does not apply a force to the second clamping plate 62, the compressed return spring 69 recovers the deformation and pushes the second clamping plate 62 in the opposite direction away from the first clamping plate 61, causing the second clamping plate 62 to automatically return to its original position.

[0033] like Figure 1 、 Figure 2 and Figure 4 As shown, the driving mechanism 7 includes a support rod 71, one end of which is fixed to the telescopic end of the lifting mechanism 4, and the other end of the support rod 71 is fixed to a fixing frame 72, on which a driving motor 73 is fixed. The output shaft of the driving motor 73 is fixed to an eccentric wheel 74 that abuts against the second clamping plate 62. In this embodiment, the driving motor 73 rotates, and the driving motor 73 drives the eccentric wheel 74 to rotate. During the rotation of the eccentric wheel 74, the distance D between the position where the eccentric wheel 74 abuts against the second clamping plate 62 and the rotation center of the eccentric wheel 74 becomes larger and larger, so that under the action of the eccentric wheel 74, the eccentric wheel 74 can push the second clamping plate 62 to move toward the first clamping plate 61, and the sheet metal part can be clamped by relying on the action of the second clamping plate 62 and the second clamping plate 62. When the sheet metal workpiece is processed, the clamping force on the sheet metal workpiece needs to be released. The eccentric wheel 74 is rotated so that the distance between the position where the eccentric wheel 74 abuts the second clamping plate 62 and the rotation center of the eccentric wheel 74 is smaller than the distance D between the position where the eccentric wheel 74 abuts the second clamping plate 62 and the rotation center of the eccentric wheel 74 when the sheet metal workpiece is clamped. This allows the sheet metal workpiece to be removed from the second clamping plate 62 and the first clamping plate 61. While the eccentric wheel 74 releases the clamping force of the second clamping plate 62 and the first clamping plate 61 on the sheet metal workpiece, the reverse force of the return spring 69 can also push the second clamping plate 62 to move away from the first clamping plate 61, making it easier to remove the clamped sheet metal workpiece.

[0034] It should be noted that if Figure 4 、 Figure 5 As shown, one end of the support rod 71 is connected to the telescopic end of the lifting mechanism 4, the other end of the support rod 71 is connected to one end of the receiving rod 75, the other end of the receiving rod 75 is installed with a fixing frame 72, the bottom of the fixing frame 72 is installed with a driving motor 73, the output shaft of the driving motor 73 is connected to one end of the rotating rod 76, the eccentric wheel 74 is provided with a mounting hole 77, and the other end of the rotating rod 76 is fixedly installed in the mounting hole 77.

[0035] like Figure 1 As shown, the interior of the base 1 is hollow, with an opening at the top thereof adapted for the workbench 2. An annular support platform 5 is fixed to the inner wall of the base 1, and the workbench 2 is located inside the support platform 5 and is movably connected to the support platform 5. Because the workbench 2 bears the entire weight of the lifting mechanism 4, the clamping assembly 6, and the sheet metal parts, the support platform 5 can provide support to the workbench 2, making the rotation of the workbench 2 more stable.

[0036] Example 2

[0037] Similar to Example 1, except that Figure 1 As shown, the rotation mechanism 3 includes a connecting rod 31 that is rotatably connected to the inner bottom wall of the base 1 and fixed to the workbench 2 at the top. A worm gear 32 is fixed to the connecting rod 31, and a worm 33 is engaged on the back of the worm gear 32. One end of the worm 33 is rotatably connected to the inner wall of the base 1, and the other end of the worm 33 passes through the exterior of the base 1 and is fixed to a rotating disk 34. In this embodiment, by operating the rotating disk 34 to rotate, the rotating disk 34 drives the worm 33 to rotate, causing the worm gear 32 and the connecting rod 31 to rotate, thereby achieving rotation of the connecting rod 31 and the fixed workbench 2, achieving rotation of the clamping assembly 6 located on the workbench 2, and then promoting angular rotation of the sheet metal parts in the clamping assembly 6, facilitating subsequent processing.

[0038] like Figure 5 As shown, a locking structure 35 is connected to the rotating disk 34, and the locking structure 35 includes an insertion rod 351 inserted into the rotating disk 34, and a full circle slot 353 adapted to the insertion rod 351 is provided on the base 1, and a push plate 354 is fixed to the insertion rod 351, and a bolt 355 is threadedly connected to the push plate 354, and a threaded groove 356 adapted to the bolt 355 is provided on the rotating disk 34. In this embodiment, when the rotating disk 34 is rotated to drive the worm 33 to rotate, the worm wheel 32 and the connecting rod 31 at the axis are rotated, and the connecting rod 31 drives the top workbench 2 to rotate, thereby adjusting the angular position of the sheet metal. After the angle adjustment is completed, the insertion rod 351 is pushed to make it engage with the full circle slot 353. The friction between the insertion rod 351 and the full circle slot 353 is large, so that the rotating disk 34 will not be pushed to rotate under normal force. Then the bolt 355 is rotated so that the bolt 355 is threadedly connected to the threaded groove 356 on the rotating disk 34, which makes the connection between the insertion rod 351 and the rotating disk 34 tighter, thereby improving the stability of locking the rotating disk 34.

[0039] like Figure 1As shown, a first bearing is fixed to the bottom of the connecting rod 31, and the connecting rod 31 is rotatably connected to the inner bottom wall of the base 1 via the first bearing. The worm 33 is rotatably connected to the inner wall of the base 1 via a second bearing. The outer surface of the worm 33 is movably connected to a support seat 36 located within the base 1, and the bottom of the support seat 36 is fixed to the inner bottom wall of the base 1. In this embodiment, the left and right sides of the outer surface of the worm 33 are movably connected to the support seat 36, and the bottom of the support seat 36 is fixed to the inner bottom wall of the base 1. The support seat 36 provides a supporting force to the worm 33, thereby promoting more stable rotation of the worm 33.

[0040] Example 3

[0041] Similar to Example 1, except that Figure 1 As shown, an extrusion layer 8, which is a rubber layer, is fixed to the opposing sides of the first and second clamping plates 61, 62. Extrusion blocks 9 are also fixed to the opposing sides of the two extrusion layers 8. In this embodiment, multiple extrusion blocks 9 are fixed to the opposing sides of the two extrusion layers 8, and are evenly spaced. The arrangement of the extrusion blocks 9 and the extrusion layers 8 increases the contact area between the first and second clamping plates 61, 62 and the outer surface of the sheet metal component, improving clamping stability while preventing wear on the outer surface of the sheet metal component caused by hard contact.

[0042] The working principle of the above embodiment is:

[0043] (1) Place the sheet metal part in the installation frame 63 and between the first clamping plate 61 and the second clamping plate 62. Start the drive motor 73 to drive the eccentric wheel 74 to rotate, so that the side of the eccentric wheel 74 away from the axis gradually approaches the second clamping plate 62, and pushes the second clamping plate 62 to move toward the direction close to the first clamping plate 61, until the second clamping plate 62 and the first clamping plate 61 clamp the sheet metal part firmly. By adjusting the clamping space between the first clamping plate 61 and the second clamping plate 62, it can adapt to the clamping and fixation of sheet metal parts of different models and sizes, and realize the adjustment of the clamping position, which saves time and effort and is convenient to operate.

[0044] (2) The rotating disk 34 drives the worm 33 to rotate. Under the meshing force, the worm wheel 32 and the connecting rod 31 at the axis thereof are rotated. The connecting rod 31 drives the workbench 2 to rotate, thereby adjusting the rotation angle of the sheet metal part. The lifting mechanism 4 is started to adjust the height of the mounting frame 63, thereby adjusting the height of the sheet metal part clamped in the mounting frame 63, which is convenient for processing. The overall structure is simple, and the height and angle position of the sheet metal part can be adjusted according to processing needs. It is easy to use and highly practical.

[0045] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features 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.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
