Description

Technical Field

[0001] This application relates to the technical field of automobile anti-collision beam processing, and more particularly to an edge grinding device for automobile anti-collision beams. Background Technology

[0002] In the manufacturing process of automotive crash beams, after the crash beam body has been processed by stamping, welding and other processes, its edges usually have sharp burrs, edges or irregular protrusions. Therefore, it is necessary to grind the edges of the automotive crash beams to improve product quality.

[0003] In related technologies, the industry typically employs a motor-driven grinding disc rotation technique for grinding the edges of automotive bumper beams. This involves fixing the bumper beam to a worktable using clamps, then rotating the grinding disc at high speed using a motor. The contact friction between the grinding disc and the bumper beam's edge removes burrs and smooths the edges. However, existing grinding devices often use clamps that hold the bumper beam in a single orientation. Since automotive bumper beams are often irregularly shaped (U-shaped, L-shaped, etc.), their edges frequently contain multiple perpendicular or angled surfaces to be ground (such as the top edge, side edges, and corner edges). In practice, operators must grind one edge, pause the machine, adjust the beam's angle, re-clamp it, and then restart the machine to grind the next edge. This not only reduces production efficiency but also leads to misalignment between the edge and the grinding disc after multiple adjustments, resulting in inconsistent grinding quality across different batches or even within the same batch. Summary of the Invention

[0004] This application aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, one objective of this application is to provide an edge grinding device for automotive anti-collision beams, which can grind multiple edges of the anti-collision beam to be ground, effectively eliminating the need to pause the equipment and manually adjust the posture of the anti-collision beam, thereby effectively improving production efficiency and ensuring the consistency of product grinding quality.

The ratchet is fixedly sleeved on the shaft of the rotating shaft and located on one side of the support plate. The first motor is fixedly installed on one side wall of the support plate. The output shaft of the first motor is fixedly connected to the left end of the rotating shaft through a coupling.

[0010] Furthermore, the limiting assembly includes a rotating rod, a limiting plate, and a spring. The rotating rod is laterally disposed inside the support plate near the ratchet. Both ends of the rotating rod are rotatably connected to the inner wall of the support plate via bearings. The limiting plate is plate-shaped and fixedly sleeved on the rod body of the rotating rod. The top end of the limiting plate extends into the tooth groove of the ratchet and engages with the ratchet. The top end of the spring is fixedly installed on the bottom end of the limiting plate, and the bottom end of the spring is fixedly installed on the inner bottom wall of the support plate.

[0011] Furthermore, the lifting assembly includes a support column, a slide rod, and a hydraulic rod. The support column is hollow and fixedly installed at the top of the base. The slide rod is longitudinally fixedly installed inside the support column. The hydraulic rod is longitudinally fixedly installed at the top of the base and located inside the support column. The top of the piston rod of the hydraulic rod is fixedly connected to the bottom of the adjusting assembly.

[0012] Furthermore, the adjustment assembly includes a sliding plate and a fixing plate, wherein the sliding plate is plate-shaped and disposed inside the support column, the sliding plate has a sliding hole in the middle and is fitted onto the sliding rod through the sliding hole, the bottom end of the sliding plate is fixedly connected to the top end of the piston rod of the hydraulic rod, the fixing plate is plate-shaped and is horizontally fixedly installed between the two sliding plates, and the fixing plate is located above the support plate.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. This application, through the coordinated design of the rotating device, grinding structure, and clamping device, effectively eliminates the step of pausing the equipment to manually adjust the posture of the anti-collision beam. The rotating component, driven by the first motor, can drive the clamped and fixed anti-collision beam body to achieve angle adjustment. With the stable limit of the unidirectional rotation of the rotating shaft by the limiting component, the posture switching of the anti-collision beam from one edge to another to be ground can be completed without pausing the grinding operation. At the same time, the lifting component can drive the grinding component to quickly approach or move away from the anti-collision beam, and the adjusting component can drive the grinding component to move laterally along the edge of the anti-collision beam. The entire grinding process can effectively reduce manual intervention to adjust the workpiece posture, shorten the total time of a single grinding operation, and thus effectively improve production efficiency. In addition, it can also effectively avoid the alignment deviation caused by manual adjustment, and effectively improve the grinding quality and precision of the product.

[0017] 2. Automotive anti-collision beams have various irregular cross-sectional structures such as U-shaped and L-shaped. In the clamping device of this application, the bidirectional lead screw can drive the two clamping plates to flexibly adjust the spacing, which can adapt to anti-collision beam bodies of different width specifications. The lifting and left and right movement adjustment range of the grinding component can be flexibly adjusted according to the height and length of the anti-collision beam. The angle adjustment of the rotating component can cover the edges to be ground in all directions of the anti-collision beam. There is no need to change the clamps or adjust the overall structure of the equipment for different types of anti-collision beams, which effectively enhances the adaptability of the equipment to anti-collision beams of different specifications and structures.

Detailed Implementation

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0022] The edge grinding device for an automotive anti-collision beam according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0023] like Figures 1-8 As shown, the edge grinding device for an automotive anti-collision beam according to an embodiment of this application may include a base 100, a clamping device 300, a rotating device 400, and a grinding structure 500.

[0024] The grinding structure 500 may include a grinding component 510, a lifting component 530, and an adjusting component 520.

[0025] The lifting components 530 are provided in two and are symmetrically fixed on both sides of the top of the base 100. The adjustment component 520 is horizontally arranged between the two lifting components 530 and is slidably connected to the lifting components 530. The grinding component 510 is arranged below the adjustment component 520 and is slidably connected to the adjustment component 520.

[0026] The clamping device 300 may include two clamping components 320 and a drive component 310. The drive component 310 is fixedly installed on the top of the rotating device 400. The two clamping components 320 are symmetrically arranged on both sides of the drive component 310 and are threadedly connected to the drive component 310. The vehicle anti-collision beam body 200 is clamped between the two clamping components 320.

[0027] The rotating device 400 may include a rotating component 410 and a limiting component 420. The rotating component 410 is laterally disposed between the two lifting components 530 and located below the adjusting component 520. The limiting component 420 is disposed on one side of the rotating component 410 and is engaged with the rotating component 410.

[0028] Specifically, when grinding the edge of the car crash beam, the personnel first place the car crash beam body 200 between two clamping components 320, ensuring that the edge to be ground faces the grinding component 510. The driving component 310 drives the two clamping components 320 symmetrically arranged on both sides to move relative to each other until the two clamping components 320 firmly clamp the car crash beam body 200. Using two lifting components 530 symmetrically fixed on both sides of the top of the base 100, the adjusting component 520 connected laterally between the two lifting components 530 is driven to slide down along the lifting component 530, which drives the grinding component 510 set below the adjusting component 520 to approach the edge to be ground of the car crash beam body 200 until the grinding component 510 reaches the appropriate grinding position. Then, the grinding component 510 is controlled to slide along the adjusting component 520 to perform grinding work on the current edge to be ground of the car crash beam body 200.

[0029] After the current edge of the car anti-collision beam body 200 is polished, the lifting component 530 drives the adjusting component 520 to slide the polishing component 510 upward away from the car anti-collision beam body 200. Then, the rotating component 410, which is horizontally arranged between the two lifting components 530 and located below the adjusting component 520, is activated, which drives the top-fixed driving component 310 and the clamped car anti-collision beam body 200 to rotate synchronously. At the same time, with the help of the limiting component 420, which is arranged on one side of the rotating component 410 and engaged with it, it is ensured that the rotating component 410 drives the car anti-collision beam body 200 to rotate stably until the next edge to be polished faces the polishing component 510. The lifting component 530 adjusts the position of the adjusting component 520 and the polishing component 510 again, so that the polishing component 510 is close to the new edge to be polished on the car anti-collision beam body 200. The polishing component 510 is controlled to slide along the adjusting component 520 to complete the polishing. The above angle switching and polishing steps are repeated until all edges of the car anti-collision beam body 200 to be polished are finished.

[0030] In one embodiment of this application, such as Figure 3 , Figure 4 As shown, the drive assembly 310 may include a fixed block 311, a bidirectional lead screw 312, and a knob 313.

[0031] The fixed block 311 is hollow and fixedly installed on the top of the rotating assembly 410. The bidirectional lead screw 312 is horizontally arranged inside the fixed block 311. The two ends of the bidirectional lead screw 312 are rotatably connected to the two side walls of the fixed block 311 through bearings. The knob 313 is fixedly installed at the front end of the bidirectional lead screw 312 and extends out of the fixed block 311.

[0032] Specifically, when it is necessary to drive the two clamping components 320 to clamp or release the car anti-collision beam body 200, the operator manually rotates the knob 313 extending outside the fixing block 311. The knob 313 drives the bidirectional lead screw 312, which is horizontally arranged inside the fixing block 311, to rotate synchronously. Since the two threads on the bidirectional lead screw 312 rotate in opposite directions, and the two clamping components 320 are respectively engaged with the two threads of the bidirectional lead screw 312, when the bidirectional lead screw 312 rotates, it will drive the two clamping components 320 to move relative to or away from each other along the inside of the fixing block 311, thereby realizing the clamping and fixing or releasing operation of the car anti-collision beam body 200.

[0033] In one embodiment of this application, such as Figure 3 , Figure 4 As shown, the clamping assembly 320 may include a movable plate 321 and a clamping plate 322.

[0034] The movable plate 321 is plate-shaped and is disposed inside the fixed block 311. A threaded hole is provided in the middle of the movable plate 321 and is threadedly connected to the bidirectional lead screw 312 through the threaded hole. The clamping plate 322 is arc-shaped and is fixedly installed on the side wall of the movable plate 321 away from the center of the fixed block 311. The inner side wall of the clamping plate 322 is in contact with the outer side wall of the vehicle anti-collision beam body 200.

[0035] Specifically, when the bidirectional lead screw 312 in the drive assembly 310 rotates under the drive of the knob 313, the movable plate 321, which is threadedly connected to the bidirectional lead screw 312, moves laterally along the axis of the bidirectional lead screw 312 under the guide limit of the inner wall of the fixed block 311 (the movable plates 321 of the two clamping assemblies 320 move relative to or away from each other as the bidirectional lead screw 312 rotates). When the movable plate 321 moves, it synchronously drives the clamping plate 322 fixed on its side wall to move. When the two clamping plates 322 are relatively close, the arc-shaped inner side wall gradually fits against the outer side wall of the car anti-collision beam body 200 until a stable clamp is formed, thereby fixing the car anti-collision beam body 200. When it is necessary to release the anti-collision beam, the knob 313 is rotated in the opposite direction to make the bidirectional lead screw 312 rotate in the opposite direction, causing the two movable plates 321 and the clamping plate 322 to move away from each other. The clamping plate 322 separates from the car anti-collision beam body 200, completing the release operation.

[0036] In one embodiment of this application, such as Figure 5 , Figure 6 As shown, the rotating assembly 410 may include a support plate 414, a rotating shaft 412, a ratchet 413, and a first motor 411.

[0037] The support plate 414 is plate-shaped and is horizontally fixed between the two lifting components 530. The support plate 414 has a mounting hole in the middle. The rotating shaft 412 is horizontally inserted into the mounting hole of the support plate 414 and is rotatably connected to the support plate 414 through a bearing. The top end of the rotating shaft 412 is fixedly connected to the bottom end of the fixing block 311. The ratchet 413 is fixedly sleeved on the shaft of the rotating shaft 412 and located on one side of the support plate 414. The first motor 411 is fixedly installed on one side wall of the support plate 414. The output shaft of the first motor 411 is fixedly connected to the left end of the rotating shaft 412 through a coupling.

[0038] Specifically, when it is necessary to adjust the angle of the car anti-collision beam body 200 to grind different edges, the first motor 411 fixed on the side wall of the support plate 414 is started. The output shaft of the first motor 411 drives the rotating shaft 412, which is transversely inserted into the mounting hole of the support plate 414, to rotate through the coupling. When the rotating shaft 412 rotates, it synchronously drives the fixed block 311 fixed at the top, the clamping component 320 on the fixed block 311, and the clamped car anti-collision beam body 200 to rotate, thereby realizing the angle adjustment. At the same time, the ratchet 413 fixedly sleeved on the shaft of the rotating shaft 412 rotates synchronously with the rotating shaft 412, preparing for the subsequent cooperation with the limiting component 420 to realize the angle locking. When the car anti-collision beam body 200 rotates to the target angle, the first motor 411 is turned off, the rotating shaft 412 stops rotating, and the angle adjustment is completed.

[0039] In one embodiment of this application, such as Figure 5 , Figure 6 As shown, the limiting component 420 may include a rotating rod 422, a limiting plate 421, and a spring 423.

[0040] The rotating rod 422 is horizontally arranged inside the support plate 414 near the ratchet 413. Both ends of the rotating rod 422 are rotatably connected to the inner wall of the support plate 414 through bearings. The limiting plate 421 is plate-shaped and fixedly sleeved on the rod body of the rotating rod 422. The top end of the limiting plate 421 extends into the tooth groove of the ratchet 413 and engages with the ratchet 413. The top end of the spring 423 is fixedly installed on the bottom end of the limiting plate 421, and the bottom end of the spring 423 is fixedly installed on the inner bottom wall of the support plate 414.

[0041] Specifically, when the rotating assembly 410 drives the car anti-collision beam body 200 to adjust its angle, the rotating shaft 412 drives the ratchet 413 to rotate synchronously in the forward direction (i.e., towards the direction of switching the edge to be polished). The teeth of the ratchet 413 will exert a downward thrust on the top of the limiting plate 421. This thrust overcomes the elastic tension of the spring 423, pushing the limiting plate 421 to swing downward around the rotating rod 422. The top of the limiting plate 421 temporarily disengages from the current tooth groove and slides into the next tooth groove as the ratchet 413 rotates. At this time, the spring 423 releases its elastic tension again and pushes the limiting plate 421 upward, causing its top to swing downward again. The ratchet 413 is embedded in the new tooth groove, completing a cycle of disengagement, reset, and engagement without affecting the forward rotation and angle adjustment of the ratchet 413. When the car anti-collision beam body 200 is adjusted to the target angle and the first motor 411 stops working, if the ratchet 413 has a tendency to rotate in the opposite direction due to external force or its own inertia, the top of the limiting plate 421 will be firmly locked in the tooth groove of the ratchet 413 under the pushing action of the spring 423. The ratchet 413 is restricted from rotating in the opposite direction by mechanical blocking, thereby fixing the angle between the rotating shaft 412 and the car anti-collision beam body 200, and avoiding the impact of angle deviation on the grinding accuracy of the anti-collision beam during the grinding process.

[0042] In one embodiment of this application, such as Figure 2 , Figure 7 As shown, the lifting assembly 530 may include a support column 531, a slide bar 532, and a hydraulic rod 533.

[0043] The support column 531 is a hollow column and is fixedly installed at the top of the base 100. The slide rod 532 is fixedly installed longitudinally inside the support column 531. The hydraulic rod 533 is fixedly installed longitudinally at the top of the base 100 and located inside the support column 531. The top of the piston rod of the hydraulic rod 533 is fixedly connected to the bottom of the adjusting assembly 520.

[0044] Specifically, when it is necessary to adjust the distance between the grinding component 510 and the vehicle anti-collision beam body 200, if the grinding component 510 needs to be closer to the anti-collision beam, the hydraulic rod 533 is activated, the piston rod of the hydraulic rod 533 extends upward, and pushes the adjustment component 520 fixedly connected to it to slide upward along the slide rod 532 inside the support column 531. The adjustment component 520 simultaneously drives the grinding component 510 below to move closer to the vehicle anti-collision beam body 200 until the grinding component 510 reaches the appropriate grinding height. If the current edge grinding is completed and the grinding component 510 needs to be moved away from the anti-collision beam to switch the angle, the piston rod of the hydraulic rod 533 is controlled to retract downward, pulling the adjustment component 520 to slide downward along the slide rod 532. The grinding component 510 moves downward synchronously with the adjustment component 520, away from the vehicle anti-collision beam body 200, leaving space for the subsequent rotation component 410 to adjust the angle of the anti-collision beam. After the angle adjustment is completed, the grinding component 510 can be driven upward again by the hydraulic rod 533 to the new grinding position.

[0045] In one embodiment of this application, such as Figure 7 , Figure 8 As shown, the adjustment assembly 520 may include a slide plate 522 and a fixing plate 521.

[0046] Among them, the slide plate 522 is plate-shaped and is set inside the support column 531. The middle part of the slide plate 522 has a sliding hole and is fitted onto the slide rod 532 through the sliding hole. The bottom end of the slide plate 522 is fixedly connected to the top end of the piston rod of the hydraulic rod 533. The fixing plate 521 is plate-shaped and is horizontally fixed between the two slide plates 522. The fixing plate 521 is located above the support plate 414.

[0047] Furthermore, the adjustment assembly 520 may also include a threaded rod 524, a guide rod 525, and a third motor 523.

[0048] The threaded rod 524 is horizontally arranged inside the fixed plate 521. The two ends of the threaded rod 524 are rotatably connected to the two side walls of the fixed plate 521 through bearings. The guide rod 525 is horizontally fixedly installed inside the fixed plate 521 and parallel to the threaded rod 524. The third motor 523 is fixedly installed on one side wall of the fixed plate 521. The output shaft of the third motor 523 is fixedly connected to the left end of the threaded rod 524 through a coupling.

[0049] Specifically, the working process of the adjustment component 520 is divided into two parts: lifting linkage and lateral drive. Lifting and lifting linkage process: When the hydraulic rod 533 in the lifting assembly 530 is activated, the piston rod of the hydraulic rod 533 extends and retracts, causing the slide plate 522 fixedly connected to it to slide up and down along the slide rod 532 inside the support column 531. Since the fixed plate 521 is horizontally fixed between the two slide plates 522, the slide plate 522 will synchronously drive the fixed plate 521 and the threaded rod 524, guide rod 525 and third motor 523 on the fixed plate 521 to lift and lower as a whole, thereby linking the grinding assembly 510 to move closer to or away from the car anti-collision beam body 200, and cooperating with the lifting assembly 530 to complete the initial adjustment of the grinding height.

[0050] Lateral driving process: When the grinding component 510 needs to move laterally along the edge to be ground on the vehicle anti-collision beam body 200, the third motor 523 fixed on the side wall of the fixed plate 521 is started. The output shaft of the third motor 523 drives the threaded rod 524, which is laterally set inside the fixed plate 521, to rotate through the coupling. The grinding component 510, which is threadedly connected to the threaded rod 524, moves laterally along the axis of the threaded rod 524 and the guide rod 525 under the guidance and restriction of the guide rod 525. By controlling the rotation direction and speed of the third motor 523, the moving direction and speed of the grinding component 510 can be controlled to ensure that the grinding component 510 can move smoothly along the edge to be ground and achieve uniform grinding.

[0051] In one embodiment of this application, such as Figure 7 , Figure 8 As shown, the grinding assembly 510 may include a slider 511, a threaded sleeve 513, and a fixed sleeve 512.

[0052] The slider 511 is block-shaped and located below the fixed plate 521. The threaded sleeve 513 is plate-shaped and fixedly installed at the front of the top of the slider 511. The threaded sleeve 513 has a threaded hole in the middle and is threadedly connected to the threaded rod 524 through the threaded hole. The fixed sleeve 512 is plate-shaped and fixedly installed at the rear of the top of the slider 511. The fixed sleeve 512 has a sliding hole in the middle and is fitted onto the guide rod 525 through the sliding hole.

[0053] Furthermore, the polishing assembly 510 may also include a polishing disc 515 and a second motor 514.

[0054] The second motor 514 is fixedly installed at the bottom of the slider 511. The output shaft of the second motor 514 is vertically downward. The grinding disc 515 is disc-shaped and fixedly installed at the bottom of the output shaft of the second motor 514. The bottom of the grinding disc 515 corresponds to the edge of the car anti-collision beam body 200.

[0055] Specifically, the working process of the polishing component 510 is divided into two parts: lateral movement adjustment and edge polishing. Lateral movement adjustment process: When the third motor 523 in the adjustment component 520 starts and drives the threaded rod 524 to rotate, the threaded sleeve 513, which is threadedly connected to the threaded rod 524, will move laterally along the axial direction of the threaded rod 524 under the action of threaded transmission. At this time, the fixed sleeve 512 at the rear of the top of the slider 511 slides along the guide rod 525, restricting the rotation of the slider 511 and only guiding the slider 511 to move laterally in sync with the threaded sleeve 513. When the slider 511 moves, it synchronously drives the second motor 514 at the bottom and the grinding disc 515 to move laterally until the grinding disc 515 is aligned with the edge to be ground on the car anti-collision beam body 200, thus completing the alignment of the grinding position.

[0056] Edge grinding process: After the grinding disc 515 is aligned with the edge to be ground, the second motor 514 is started. The output shaft of the second motor 514 drives the grinding disc 515 at the bottom to rotate at high speed. At the same time, the slider 511 is continuously driven to move laterally through the adjusting component 520, so that the high-speed rotating grinding disc 515 moves smoothly along the edge to be ground of the car anti-collision beam body 200. The friction between the working surface of the grinding disc 515 and the edge of the anti-collision beam is used to remove the burrs, sharp edges and irregular protrusions of the edge. After the edge is ground, the second motor 514 is turned off, and the grinding component 510 is driven to move upward away from the anti-collision beam through the lifting component 530. After the rotating component 410 adjusts the angle of the anti-collision beam, the above steps are repeated to grind the next edge.

[0057] In summary, the edge grinding device for automotive anti-collision beams in this application embodiment can grind multiple edges of the anti-collision beam to be ground, effectively eliminating the need to pause the equipment and manually adjust the posture of the anti-collision beam, thereby effectively improving production efficiency and ensuring the consistency of product grinding quality.
