Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to a clamping device. Background Technology

[0002] As the automotive industry moves towards new energy, intelligentization, and lightweighting, new energy vehicles place higher demands on the structural design and manufacturing processes of their components. As a crucial safety structural component of the vehicle body, the quality of the anti-collision beam directly affects the overall safety performance and reliability of the vehicle. To reduce vehicle weight and increase driving range, anti-collision beam materials are gradually shifting from traditional steel to lightweight, high-strength materials such as aluminum alloys and carbon fiber composites. However, these lightweight materials are characterized by low rigidity and thin-walled structures, making them highly susceptible to deformation and vibration during processing. In existing technologies, anti-collision beams typically require multiple clamping operations to complete multi-faceted processing. This not only leads to the accumulation of errors during processing but also results in low clamping efficiency and complex operations, impacting yield and production efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figures 1 to 10As shown, an embodiment of this utility model provides a clamping device for clamping a car anti-collision beam 10, including a positioner, a base 20, a positioning structure 30, a pressing structure 40, a supporting structure 50, and a clamping structure 60. The base 20 is fixed on the positioner, which is used to drive the base 20 to rotate. The positioning structure 30, the pressing structure 40, the supporting structure 50, and the clamping structure 60 are spaced apart on the base 20. The positioning structure 30 is used to position the anti-collision beam 10, the pressing structure 40 is used to press the anti-collision beam 10, the supporting structure 50 is used to support the anti-collision beam 10, and the clamping structure 60 is used to clamp the anti-collision beam 10.

[0032] In this embodiment, through the fixed connection between the base 20 and the positioner, the clamping device can achieve multi-angle flipping during processing, enabling the anti-collision beam 10 to complete the positioning and cutting of different processing surfaces without disassembly. This reduces the number of repeated clamping operations, thereby avoiding the cumulative positioning error caused by multiple clamping operations and improving processing accuracy and production efficiency. The flipping angle can be selected as 90° or 180°. Moreover, by integrating the positioner, positioning structure 30, clamping structure 40, support structure 50, and clamping structure 60 onto the base 20, not only can the positioning accuracy and clamping stability requirements of the anti-collision beam 10 be met during multi-face processing, but the clamping preparation time can also be shortened and production efficiency improved.

[0033] like Figure 3 As shown, the clamping structure 60 includes a first clamping member 61, a second clamping member 62, and a driving mechanism. The driving mechanism is connected to both the first clamping member 61 and the second clamping member 62. The driving mechanism drives the first clamping member 61 and the second clamping member 62 to move closer to or further away from each other. The first clamping member 61 and the second clamping member 62 are used to clamp or release the reinforcing ribs of the anti-collision beam 10.

[0034] In this embodiment, by setting the first clamping member 61 and the second clamping member 62, the anti-collision beam 10 can be precisely positioned and clamped before processing due to its thin wall and irregular shape. After processing, it can be automatically released and avoided, thus preventing interference from the clamping structure 60 from affecting the loading, unloading, and tool movement trajectory. Moreover, through the control of the drive mechanism, the first clamping member 61 and the second clamping member 62 can apply a balanced and controllable clamping force to the reinforcing rib, ensuring the rigid support and stable fixation of the anti-collision beam 10 during processing. This not only prevents the anti-collision beam 10 from shifting or vibrating during cutting, but also avoids material indentation or structural deformation caused by excessive clamping force, thereby improving the reliability of clamping and surface quality.

[0035] like Figure 3As shown, the first clamping member 61 has a plurality of first protruding ends 611 on the side facing the second clamping member 62, and the second clamping member 62 has a plurality of second protruding ends 621 on the side facing the first clamping member 61. The plurality of first protruding ends 611 and the plurality of second protruding ends 621 are used to clamp or release the reinforcing ribs of the anti-collision beam 10.

[0036] In this embodiment, the reinforcing ribs of the anti-collision beam 10 are clamped or released by multiple first protruding ends 611 and multiple second protruding ends 621, so that the clamping force can be evenly distributed on multiple contact points. This avoids the problem of concentrated stress in only local areas in traditional clamping structures, thereby preventing local indentation, deformation, or slippage in the reinforcing rib area of ​​the anti-collision beam 10 due to uneven force. Moreover, it can form multi-point support and multi-directional constraint during the clamping process, improve clamping stability without increasing the overall clamping force, enhance the vibration resistance of the workpiece under dynamic loads such as cutting vibration, keep the anti-collision beam 10 in a stable posture during processing, and further improve the dimensional accuracy of the processed surface.

[0037] Specifically, the clamping structure 60 also includes a lifting mechanism connected to the drive mechanism. The lifting mechanism is used to lift the first clamping member 61 and the second clamping member 62. During the clamping stage, the lifting mechanism can drive the first clamping member 61 and the second clamping member 62 to the clamping position to achieve quick and accurate alignment with the reinforcing ribs of the anti-collision beam 10. During the processing stage, the first clamping member 61 and the second clamping member 62 can be lowered to the clamping state to provide stable support and positioning constraints for the anti-collision beam 10. After processing, the lifting mechanism can drive the first clamping member 61 and the second clamping member 62 to move down to the avoidance position to avoid interference between the clamp and the anti-collision beam 10, and facilitate the loading and unloading operations of the anti-collision beam 10.

[0038] like Figure 1 As shown, the positioning structure 30 includes a first positioning pin 31, a second positioning pin 32, and a positioning seat 33. The first positioning pin 31 and the second positioning pin 32 are respectively disposed at both ends of the base 20, and the positioning seat 33 is disposed between the first positioning pin 31 and the second positioning pin 32.

[0039] In this embodiment, the first positioning pin 31 and the second positioning pin 32 respectively engage with the holes at both ends of the anti-collision beam 10 to limit the horizontal movement of the anti-collision beam 10, preventing translational or rotational errors during clamping. The positioning seat 33 is positioned between the first positioning pin 31 and the second positioning pin 32, and by fitting against the lower surface of the anti-collision beam 10, it provides Z-axis positioning, ensuring that the vertical orientation of the anti-collision beam 10 remains consistent, thereby guaranteeing the consistency and relative accuracy of the reference points of each machined surface. By employing a positioning method with one surface and two pins, the degrees of freedom of the anti-collision beam 10 are fully constrained.

[0040] like Figure 1 and Figure 3 As shown, the top of the first positioning pin 31 and the second positioning pin 32 are provided with a tapered surface for guiding the anti-collision beam 10. The positioning seat 33 includes a guide post 331 and a support seat 332. The support seat 332 is disposed on the base 20. The guide post 331 and the support seat 332 are fixedly connected. The guide post 331 positions and guides the anti-collision beam 10, and the support seat 332 supports the guide post 331.

[0041] In this embodiment, the tapered surfaces at the top of the first positioning pin 31 and the second positioning pin 32 can automatically guide and correct the positioning holes of the anti-collision beam 10 during placement, allowing the anti-collision beam 10 to automatically slide into the positioning position under gravity or manual pushing, thus improving the efficiency of clamping operations. Furthermore, it can avoid problems such as jamming and damage caused by manual alignment deviations, ensuring the smoothness and repeatability of the anti-collision beam 10 during clamping.

[0042] The guide post 331 in the positioning seat 33 is used to vertically position the lower surface or feature hole of the anti-collision beam 10 to ensure the positioning of the anti-collision beam 10 in the Z direction. The support seat 332 provides support for the guide post 331 to prevent the guide post 331 from shifting or sinking under stress, and to ensure durability in long-term use.

[0043] like Figure 1 As shown, the clamping structure 40 includes an auxiliary clamping mechanism 41, multiple end clamping mechanisms 42, and multiple multi-point clamping mechanisms 43. The auxiliary clamping mechanism 41, end clamping mechanism 42, and multi-point clamping mechanism 43 are spaced apart on the base 20. The auxiliary clamping mechanism 41, end clamping mechanism 42, and multi-point clamping mechanism 43 clamp different positions of the anti-collision beam 10 respectively.

[0044] In this embodiment, the auxiliary clamping mechanism 41 is used to clamp the ends of the anti-collision beam 10. By applying downward force, the anti-collision beam 10 is pressed against the support structure 50 to prevent displacement of the anti-collision beam 10 under the action of cutting force. The end clamping mechanism 42 is set at both ends of the anti-collision beam 10. For the end overhanging area with low stiffness, it applies a stable clamping force to suppress end vibration and torsional deformation, reduce the vibration phenomenon caused by uneven force during processing, and ensure the processing accuracy and surface quality of the end area. The multi-point clamping mechanism 43 is distributed in the middle of the anti-collision beam 10 to realize multi-point clamping. This can clamp the anti-collision beam 10 according to different shapes and stress characteristics, which can prevent processing vibration and deformation, and maintain the positioning accuracy and surface flatness of the anti-collision beam 10.

[0045] like Figure 5As shown, the end clamping mechanism includes a first connecting seat 421, a first driving cylinder 422, a first limiting member 423, and a first clamping member 424. The first connecting seat 421 is disposed on the base 20, and the first driving cylinder 422 is disposed on the first connecting seat 421. The first driving cylinder 422 is connected to the first clamping member 424 and drives the first clamping member 424 to move. One end of the first limiting member 423 is hinged to the first connecting seat 421, and the other end of the first limiting member 423 is hinged to the first clamping member 424. The first limiting member 423 is used to limit the movement trajectory of the first clamping member 424, and the first clamping member 424 is used to clamp the anti-collision beam 10.

[0046] In this embodiment, the first drive cylinder 422 serves as a power output unit, enabling the first clamping member 424 to be driven, thus allowing the clamping action to be repeated. The first limiting member 423 constrains the movement direction and stroke range of the first clamping member 424 during the clamping process, forming a lever-type guiding mechanism to prevent the first clamping member 424 from deflecting or swaying under force, thereby ensuring that the clamping force always acts perpendicularly on the surface of the anti-collision beam 10 and preventing the anti-collision beam 10 from shifting due to incorrect force direction.

[0047] like Figure 6 and Figure 7 As shown, the auxiliary clamping mechanism 41 includes a second connecting seat 411, a second driving cylinder 412, and a second clamping member 413. The second connecting seat 411 is disposed on the base 20, the second driving cylinder 412 is disposed on the second connecting seat 411, and the second clamping member 413 is connected to the second driving cylinder 412. The second driving cylinder 412 drives the second clamping member 413 to move, and the second clamping member 413 is used to clamp the anti-collision beam 10. The multi-point clamping mechanism 43 includes a third connecting seat 431, a third driving cylinder 432, and a third clamping member 433. The third connecting seat 431 is disposed on the base 20, the third driving cylinder 432 is disposed on the third connecting seat 431, and the third clamping member 433 is connected to the third driving cylinder 432. The third driving cylinder 432 drives the third clamping member 433 to move, and the third clamping member 433 is used to clamp the anti-collision beam 10.

[0048] In this embodiment, the auxiliary clamping mechanism 41 and the multi-point clamping mechanism 43 are spaced apart on the base 20, each controlled by an independent drive cylinder. They can flexibly apply force according to the characteristics of different parts of the anti-collision beam 10 to achieve zoned clamping. The auxiliary clamping mechanism 41 mainly further clamps the end based on the end clamping mechanism 42, ensuring that the main reference surface of the anti-collision beam 10 is fully in contact with the positioning seat 33, preventing displacement under machining load. The multi-point clamping mechanism 43 clamps the long overhanging part or thin-walled section in the middle of the anti-collision beam 10. Through multi-point support and uniform force distribution, it effectively disperses the force on the workpiece and avoids local pressure deformation. In this way, through the coordinated action of multiple cylinders, the anti-collision beam 10 maintains a stable posture when the cutting load changes, suppressing machining vibration and deformation trends.

[0049] Optionally, the auxiliary clamping mechanism 41 and the multi-point clamping mechanism 43 can be adjusted in position or configured in number according to different models of the anti-collision beam 10.

[0050] like Figure 8 and Figure 9 As shown, the support structure 50 includes multiple spaced auxiliary support mechanisms 51 and lateral support mechanisms 52. The auxiliary support mechanisms 51 are vertically oriented and include a lifting seat 511 and a support column 512. The lifting seat 511 drives the support column 512 to rise and fall. The support column 512 includes a first cylindrical section 5121, a second cylindrical section 5122, and a conical section 5123. The two ends of the conical section 5123 are respectively connected to one end of the first cylindrical section 5121 and one end of the second cylindrical section 5122. The other end of the second cylindrical section 5122 is connected to the lifting seat 511. The first cylindrical section 5121 is used to support the anti-collision beam 10. The lateral support mechanism 52 includes a base 521 and a support member 522. The support member 522 is disposed on the base 521, and the base 521 is disposed on the base 20. The support member 522 is used to support the anti-collision beam 10.

[0051] In this embodiment, the auxiliary support mechanism 51 can be adjusted in height according to the different structural heights and shapes of the anti-collision beam 10. After clamping, it actively rises to the position in contact with the anti-collision beam 10, providing Z-axis support force. This ensures the flatness of the reference surface of the anti-collision beam 10 during clamping and processing, and avoids vibration caused by local suspension or uneven force on the anti-collision beam 10. Moreover, the support column 512 adopts a structure composed of a first cylindrical section 5121, a second cylindrical section 5122, and a conical section 5123. In this way, the conical section 5123 can play a flexible guiding and force buffering role, and can achieve fine adjustment during the workpiece loading process, ensuring that the support point is fully in contact with the bottom surface of the workpiece without generating impact concentration or indentation. The first cylindrical section 5121 provides the main support force to ensure the stability of the anti-collision beam 10. The second cylindrical section 5122 is connected to the lifting seat 511, which improves the load-bearing rigidity and adjustment reliability of the overall structure. This not only supports the anti-collision beam 10, but also takes into account the vibration resistance and impact reduction performance. In addition, the lateral support mechanism 52 forms a limiting constraint in the direction of the side wall of the anti-collision beam 10 by setting the base 521 and the support member 522, which can prevent the anti-collision beam 10 from lateral displacement or swaying under the action of cutting force.

[0052] In the solution of this application, by combining the auxiliary support mechanism 51 and the lateral support mechanism 52, the support structure 50 achieves multi-point and multi-directional coordinated support during the processing, so that the anti-collision beam 10 is stable during multi-face processing. At the same time, the lifting and adjustment function improves the adaptability of the fixture to anti-collision beams 10 of different specifications and avoids processing deviations caused by support errors.

[0053] like Figure 10 As shown, the clamping device also includes multiple guide structures 70, which are spaced apart on the base 20. Each guide structure 70 includes a cylindrical guide member 71 and a fixed seat 72. The fixed seat 72 is located on the base 20, and the guide member 71 is located on the fixed seat 72. The guide member 71 guides the anti-collision beam 10.

[0054] In this embodiment, multiple guide structures 70 form a multi-point distribution of guides along the clamping path of the anti-collision beam 10. This guides the anti-collision beam 10 during placement, ensuring its gradual and precise alignment with the positioning structure 30 as it falls or is pushed laterally, thus achieving fast, smooth, and accurate clamping guidance. Furthermore, the guide member 71 is cylindrical, which provides a sliding guidance effect upon contact with the anti-collision beam 10, preventing scratches or jamming of the anti-collision beam 10 due to sharp corners or edges.

[0055] like Figure 1 and Figure 2As shown, the clamping device also includes multiple blowing elements 80, which are respectively disposed at both ends of the base 20. The blowing elements 80 are used to clean the clamping device to prevent chips and impurities from adhering to the contact surfaces of the positioning structure 30 and the clamping structure 40, thus avoiding affecting the clamping and positioning accuracy in the next round. The high-speed airflow generated by the blowing elements 80 can flow along the surface of the base 20, covering key parts of the fixture, achieving full coverage and thorough cleaning, and ensuring the cleanliness of the fixture surface.
