[0002] In the field of modern industrial manufacturing, sheet metal parts, as structural components made of thin metal sheets through processes such as stamping, bending, and cutting, are widely used in many industries such as aerospace, automobile manufacturing, electronic equipment, medical devices, and engineering machinery due to their advantages of lightweight, high strength, and controllable cost. When drilling holes in some irregularly shaped sheet metal parts, it is necessary to use fixing fixtures to fix them and maintain stability.

[0003] In the existing technology, sheet metal parts come in various shapes. Sheet metal parts with irregular curved surfaces, asymmetrical structures, or inclined structures are more difficult to handle. For different sheet metal parts, workers often need to change different types of fixtures, which makes the operation more troublesome.

[0004] Therefore, this utility model provides a multi-station fixing fixture for irregularly shaped sheet metal parts. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the challenges of handling sheet metal parts with varying shapes, irregular curved surfaces, asymmetrical structures, or inclined surfaces, where workers often need to change different types of fixtures for different sheet metal parts, making the operation quite cumbersome.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A multi-station fixing fixture for irregularly shaped sheet metal parts, comprising a base plate, a clamping mechanism disposed on the top of the base plate, the clamping mechanism comprising: The irregular clamping assembly includes a pair of first sliding grooves opened on the top of the base plate, a set of T-shaped blocks slidably connected in the first sliding grooves, a support plate fixed to the top of the pair of T-shaped blocks, a clamping plate fixed to the top of the support plate, a circular rod connected to the top of the support plate through a set movable component, a ball fixed to one end of the circular rod near the clamping plate, a cylindrical block rollingly connected on the ball, a support block fixed to the side wall of the cylindrical block, and a set of top blocks fixed to the side wall of the support block; Two-sided clamping components are mounted on the support plate for clamping the workpiece from both sides; A fixing component is installed on the base plate to fix the T-shaped block.

[0007] Preferably, the movable component includes a set of uprights fixed to the top of the support block, a pair of square rods fixed between opposite sidewalls of the pair of uprights, a movable block fixed to the set of square rods, and the end of the circular rod away from the sphere fixed to the sidewall of the movable block.

[0008] Preferably, a rectangular block is fixed to the top of the support plate, and a pair of electric actuators are fixed to the side of the rectangular block near the movable block, with the telescopic ends of the electric actuators fixed to the side wall of the movable block.

[0009] Preferably, the two-sided clamping assembly includes a pair of sliding slots opened on the base plate, a sliding block is slidably connected in the sliding slot, a clamping block is fixedly connected to the top of the sliding block, and a concave frame is fixedly connected to the bottom of the support plate.

[0010] Preferably, a motor is fixedly connected to the top of the concave frame, a drive rod is provided at the output end of the motor, an adjusting rod is fixedly connected to the top of the drive rod, and connecting rods are rotatably connected to the tops of both ends of the adjusting rod through a first rotating shaft.

[0011] Preferably, the fixing component includes a pair of second sliding grooves opened on the base plate, a set of nuts slidably connected in the second sliding grooves, a connecting block fixedly connected to the vertical side wall of the T-shaped block, a circular hole opened on the connecting block, and a bolt threadedly connected to the nut, with the bolt passing through the circular hole.

[0012] The beneficial effects of this utility model are as follows: 1. The present invention provides a multi-station fixing fixture for irregularly shaped sheet metal parts. Through the rolling connection between a ball and a cylindrical block, the cylindrical block can flexibly adjust its angle according to the curvature of the workpiece's irregular surface. With the support of multiple sets of top blocks providing multi-point support, it can adapt to various irregular surfaces such as arcs and irregular protrusions. Furthermore, through the clamping cooperation of a pair of clamping blocks, it achieves four-sided clamping. This solves the problem in the prior art where sheet metal parts have different shapes, irregular curved surfaces, asymmetrical structures, or inclined surface structures, which are difficult to handle. For different sheet metal parts, operators often need to change different types of fixtures, making the operation cumbersome.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, a multi-station fixing fixture for irregularly shaped sheet metal parts according to an embodiment of the present invention includes a base plate 1. A clamping mechanism is provided on the top of the base plate 1. The clamping mechanism includes an irregularly shaped clamping assembly, including a pair of first sliding grooves 2 opened on the top of the base plate 1. A set of T-shaped blocks 3 with a "T"-shaped cross-section are slidably connected in the first sliding grooves 2. A support plate 4 with a rectangular shape is fixed to the top of the pair of T-shaped blocks 3 and is horizontally fixed to the top of the two sets of T-shaped blocks 3. A clamping plate 5 is fixed to the top of the support plate 4. A circular rod 6 is connected to the top of the support plate 4 through a set movable component. The circular rod 6 is close to the clamping plate 5. A ball 7 is fixedly connected to one end of the holding plate 5. A cylindrical block 8 is rolled on the ball 7. The cylindrical block 8 has a spherical groove inside that matches the ball 7. The ball 7 and the cylindrical block 8 are rolled together, which allows the cylindrical block 8 to roll at multiple angles. Through the friction between the two, the cylindrical block 8 can maintain stability without being affected by external forces. A support block 9 is fixedly connected to the side wall of the cylindrical block 8. A set of top blocks 10 is fixedly connected to the side wall of the support block 9. The two-sided clamping components are set on the support plate 4 for clamping the workpiece on both sides. The fixing components are set on the base plate 1 for fixing the T-shaped block 3.

[0018] The movable component includes a set of uprights 11 fixed to the top of the support block 9, a pair of square rods 12 fixed between opposite sidewalls of the pair of uprights 11 to provide a sliding track for the movable block 13, and a movable block 13 fixed to the set of square rods 12, which is sleeved on the square rods 12 and can slide horizontally along the square rods 12 to improve the function of supporting the circular rod 6. The end of the circular rod 6 away from the sphere 7 is fixed to the sidewall of the movable block 13.

[0019] A rectangular block 14 is fixed to the top of the support plate 4. A pair of electric actuators 15 are fixed to the side of the rectangular block 14 near the movable block 13. The telescopic ends of the electric actuators 15 are fixed to the side wall of the movable block 13.

[0020] The clamping components on both sides include a pair of sliding slots 16 opened on the base plate 1, a sliding block 17 is slidably connected in the sliding slots 16, a clamping block 18 is fixedly connected to the top of the sliding block 17, and a concave frame 19 is fixedly connected to the bottom of the support plate 4.

[0021] A motor 20 is fixedly connected to the top of the concave frame 19. The servo motor 20 is selected to provide power for the movement of a pair of sliding blocks 17. The output end of the motor 20 is provided with a drive rod 21. An adjusting rod 22 is fixedly connected to the top of the drive rod 21. The top of both ends of the adjusting rod 22 are rotatably connected to a connecting rod 23 through a first rotating shaft. The end of the connecting rod 23 away from the adjusting rod 22 is rotatably connected to the bottom of the sliding block 17 through a second rotating shaft, forming a "crank-connecting rod mechanism" to drive the movement of a pair of sliding blocks 17.

[0022] During operation, the cylindrical block 8 can flexibly adjust its angle according to the curvature of the workpiece's irregular surface through the rolling connection between the sphere 7 and the cylindrical block 8. With the support of multiple sets of top blocks 10 on the support block 9, it can adapt to various irregular surfaces such as arcs and irregular protrusions. Furthermore, through the clamping cooperation of a pair of clamping blocks 18, it can achieve four-sided clamping. This solves the problem in the existing technology that sheet metal parts have different shapes, irregular curved surfaces, asymmetrical structures, or inclined structures, which are difficult to handle. For different sheet metal parts, operators often need to change different types of fixtures, which is quite troublesome to operate.

[0023] The fixing component includes a pair of second sliding grooves 24 opened on the base plate 1. A set of nuts 25 are slidably connected in the second sliding grooves 24. The nuts 25 can only slide in the second sliding grooves 24 and cannot rotate. A connecting block 26 is fixed to the vertical side wall of the T-shaped block 3. A circular hole 27 is opened on the connecting block 26. A bolt 28 is threaded on the nut 25 and passes through the circular hole 27.

[0024] During operation, the fixture is "detachable" by bolt 28. When adjusting, simply loosen bolt 28 to move the fixture position, or directly add or remove fixtures to change the quantity. This avoids the problem of traditional multi-station fixtures having no change in position or quantity, which leads to mismatch in position during drilling, affecting processing and having poor adaptability.

[0025] Working principle: First, loosen the bolts 28 of the fixing component, push the T-block 3 to slide along the first sliding groove 2 at the top of the base plate 1, and drive the top fixed support plate 4 and clamping plate 5 to move synchronously; after the work position is determined, pass the bolts 28 through the circular hole 27 of the connecting block 26 and screw them into the nut 25 that is slidably connected in the second sliding groove 24. Through the thread engagement of the bolts 28 and the nut 25, the positions of the connecting block 26 and the T-block 3 are locked, completing the pre-adjustment of the work position and preventing the support plate 4 from shifting during subsequent processing. Adjust the position and number of the fixing fixtures according to the requirements.

[0026] The motors 20 of the clamping assemblies on both sides are started. The output end of the motor 20 drives the drive rod 21 to rotate. The adjusting rod 22 fixed to the top of the drive rod 21 rotates synchronously with the drive rod 21. When the adjusting rod 22 rotates, the connecting rods 23 connected to its two ends through the first rotating shaft move accordingly. The end of the connecting rod 23 away from the adjusting rod 22 pulls the sliding block 17 along the sliding groove 16 on the base plate 1 through the second rotating shaft. Since the connecting rods 23 at both ends of the adjusting rod 22 are symmetrically distributed, during the rotation of the adjusting rod 22, the sliding blocks 17 on both sides will move synchronously along the sliding groove 16 towards the workpiece, causing the clamping blocks 18 fixed to the top of the sliding blocks 17 to move synchronously towards the two sides of the workpiece until the inner side of the clamping block 18 is tightly fitted with the two sides of the workpiece.

[0027] The irregularly shaped sheet metal part is placed on top of the support plate 4, with one side of the irregular surface facing the support block 9. The electric actuator 15 of the moving component is activated: the telescopic end of the electric actuator 15 extends, pushing the moving block 13 fixed to its end to slide along the square rod 12; when the moving block 13 moves, it drives the circular rod 6 fixed to its side wall to move synchronously, so that a set of top blocks 10 approach the irregular surface of the workpiece. Since the sphere 7 can roll inside the cylindrical block 8, the cylindrical block 8 can adaptively adjust its angle according to the curvature of the irregular surface of the workpiece; a set of top blocks 10 on the side wall of the support block 9 simultaneously contact the irregular surface of the workpiece, and through the multi-point support of multiple sets of top blocks 10 and the clamping plate 5, the irregularly shaped sheet metal part is clamped and fixed.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
