Description

Technical Field

[0001] This invention relates to the field of casting bracket processing technology, and in particular to an adaptive clamping processing device and processing method for irregularly shaped brackets. Background Technology

[0002] Airbag brackets are key support components widely used in vehicle suspension systems. In the automotive manufacturing field, airbag brackets are important structural components in independent suspension systems and airbag systems. The products have complex shapes and have high requirements for dimensional tolerances, geometric tolerances, and surface treatment. Drilling is usually required during their processing and manufacturing. The drilling process directly affects the assembly performance and service life of the airbag bracket.

[0003] Because airbag supports are usually irregular in shape, existing fixtures are unable to reliably clamp and accurately position irregularly shaped workpieces. During the drilling process, the workpiece is prone to displacement, affecting the drilling accuracy. Existing drilling equipment for irregularly shaped supports, such as airbag supports, has limited versatility and cannot simultaneously meet the dual requirements of clamping stability and flexible adjustment of drilling position. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: due to the irregular shape of airbag supports, existing fixtures are difficult to reliably clamp and accurately position irregular workpieces; workpieces are prone to displacement during drilling, affecting drilling accuracy; existing drilling equipment for irregular airbag support castings has limited versatility and cannot simultaneously meet the dual requirements of clamping stability and flexible adjustment of drilling position; therefore, an adaptive clamping processing device and processing method for irregular supports is proposed.

Two lifting mechanisms are respectively connected to two limiting mechanisms.

[0008] Preferably, the linkage mechanism includes symmetrically arranged fourth air pipes, and a push shaft is slidably inserted into each of the two fourth air pipes. The linkage mechanism also includes two linkage shafts, one end of which is rotatably connected to the back of two top blocks respectively. A convex shaft is provided below the two linkage shafts. The end of the push shaft away from the fourth air pipe is fixedly connected to the convex shaft. The two fourth air pipes are connected together through a third air pipe. In the same linkage mechanism, the two third air pipes are connected together through a second air pipe. The second air pipe is connected to a first air pipe through a three-way pipe. The first air pipe is connected to a fifth cylinder.

[0009] Preferably, both linkage shafts on the same linkage mechanism are provided with sliding grooves, and each sliding groove is slidably connected to a connecting shaft. The end of the connecting shaft away from the linkage shaft is rotatably connected to the top block, and an intersection point is formed between the two connecting shafts.

[0010] Preferably, a first cylinder is fixedly installed on each of the two bases, the driving end of the first cylinder is fixedly connected to the lower end of the first bracket, and a third cylinder is symmetrically fixedly installed on the fixed frame, the driving end of the third cylinder is fixedly connected to the upper end of the first bracket, and the third cylinder and the second cylinder are respectively located on both sides of the first bracket.

[0011] Preferably, the first bracket has symmetrically arranged movable slots on both sides, and a first lead screw is rotatably installed in each of the two movable slots. A first motor is fixedly installed at the bottom of the movable slot, and the drive end of the first motor is fixedly connected to the first lead screw. The two ends of the second bracket are slidably inserted into the two movable slots, and the two first lead screws are threaded through the two ends of the second bracket.

[0012] Preferably, a second lead screw is rotatably mounted inside the second bracket, a second motor is fixedly mounted at one end of the second bracket, the drive end of the second motor is fixedly connected to the second lead screw, a fixed shaft is fixedly connected at one end of the housing, the fixed shaft slides inside the second bracket, and the thread of the second lead screw passes through the fixed shaft.

[0013] Preferably, multiple rollers are symmetrically rotatably connected to both sides of the first bracket, the rollers roll on the base, limit blocks are provided on both sides of the upper end of the first bracket, and limit grooves are provided on the fixed frame to cooperate with the limit blocks.

[0014] Preferably, the lifting mechanism includes a fourth cylinder fixedly connected to the bottom of the top block, the driving end of the fourth cylinder being fixedly connected to a first connecting plate, the first connecting plate being fixedly connected to a second connecting plate, the second connecting plate being provided with four legs, the four legs passing through the top block, and two of the legs being connected to a third air pipe.

[0023] 1. This invention achieves adaptive clamping of irregularly shaped supports by setting four symmetrically arranged top blocks and a linkage mechanism. The four top blocks can move at different distances relative to the fourth air tube, thereby achieving effective clamping and fixing of irregularly shaped supports. A stable triangular support structure is formed between the top blocks, the convex shaft, and the linkage shaft, which effectively maintains the stability of the clamping position and the reliability of the clamping effect.

[0024] 2. This invention achieves precise positioning and flexible adjustment of the drill bit in three-dimensional space through multi-axis linkage and multi-cylinder coordinated drive.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Reference Figures 1-4 An adaptive clamping and processing device for irregularly shaped brackets includes a base 1 and a fixed frame 2 arranged symmetrically. A first bracket 3 that moves on a horizontal plane is slidably arranged on the base 1. A second bracket 11 that moves on a vertical plane is installed on the first bracket 3. The first bracket 3 is located inside the fixed frame 2. Two second cylinders 10 are symmetrically fixed on the fixed frame 2. The driving end of the second cylinder 10 is fixedly connected to the first bracket 3. A housing 6 is horizontally slidably connected to the second bracket 11. A drill bit 20 for drilling holes in the irregularly shaped bracket is rotatably installed on the housing 6.

[0040] An operating platform 4 is provided between the two bases 1. The operating platform 4 has a slot 30 for engaging the side of the irregular bracket. A limiting mechanism is symmetrically arranged on the operating platform 4. Each limiting mechanism includes four symmetrically arranged top blocks 5. Two adjacent top blocks 5 are connected together by a linkage mechanism. A lifting mechanism is symmetrically arranged at the bottom of the operating platform 4. The two lifting mechanisms are respectively connected to the two limiting mechanisms.

[0041] Reference Figures 6-8The linkage mechanism includes symmetrically arranged fourth air pipes 25, and a push shaft 16 is sealed and slidably inserted into each of the two fourth air pipes 25. The linkage mechanism also includes two linkage shafts 26, one end of which is rotatably connected to the back of the two top blocks 5 respectively. A convex shaft 27 is provided below the two linkage shafts 26. The end of the push shaft 16 away from the fourth air pipe 25 is fixedly connected to the convex shaft 27. The two fourth air pipes 25 are connected together through a third air pipe 37. In the same linkage mechanism, the two third air pipes 37 are connected together through a second air pipe 21. The second air pipe 21 is connected to a first air pipe 23 through a three-way pipe 24. The first air pipe 23 is connected to a fifth cylinder. In use, the first air pipe 23 is connected to the fifth cylinder at the far end. The first air pipe 23 is connected to the second air pipe 21, the second air pipe 21 is connected to the third air pipe 37, and the third air pipe 37 is connected to the fourth air pipe 25. When the fifth cylinder extends or retracts, it changes the internal air pressure of the air pipe structure, thereby pushing the push shaft 16 to extend or retract relative to the fourth air pipe 25. This simultaneously drives the four top blocks 5 to move. The four top blocks 5 move closer to the center to clamp the irregularly shaped bracket. The irregularly shaped bracket is irregular in shape. Each top block 5 stops after approaching the irregularly shaped bracket until all four top blocks 5 stop and can no longer move. Then, the top blocks 5 adaptively adjust the relative distance. The distance that the four top blocks 5 move relative to the fourth air pipe 25 can be different as needed, thereby effectively clamping and fixing the irregularly shaped bracket.

[0042] Both linkage shafts 26 on the same linkage mechanism are provided with sliding grooves, and connecting shafts 28 are slidably connected to the sliding grooves. The end of the connecting shaft 28 away from the linkage shaft 26 is rotatably connected to the top block 5, and an intersection point is formed between the two connecting shafts 28. One end of one linkage shaft 26 is rotatably connected to one top block 5, and is rotatably connected to the other top block 5 through one connecting shaft 28. The connecting shaft 28 plays a supporting and stabilizing role. Two structures are connected to one top block 5. When the top block 5 contacts and abuts against the surface of the irregular bracket, a triangular structure is formed between the top block 5, the convex shaft 27, and the linkage shaft 26, which helps to maintain the stability of the position of the top block 5 and the stability of the clamping effect.

[0043] The lifting mechanism includes a fourth cylinder 31 fixedly connected to the bottom of the top block 5. A first connecting plate 32 is fixedly connected to the drive end of the fourth cylinder 31. A second connecting plate 29 is fixedly connected to the first connecting plate 32. The second connecting plate 29 has four legs that pass through the top block 5, with two legs connected to a third air pipe 37. When the clamping position of the top block 5 needs to be changed, the fourth cylinder 31 drives the first connecting plate 32 to move via its drive end. The first connecting plate 32 then drives the second connecting plate 29 to move, which in turn drives the third air pipe 37 to move, thereby causing the connected top block 5 to move up and down.

[0044] Reference Figures 1-5A first cylinder 19 is fixedly installed on each of the two bases 1. The driving end of the first cylinder 19 is fixedly connected to the lower end of the first bracket 3. A third cylinder 9 is also symmetrically fixedly installed on the fixed frame 2. The driving end of the third cylinder 9 is fixedly connected to the upper end of the first bracket 3. The third cylinder 9 and the second cylinder 10 are respectively located on both sides of the first bracket 3. The second cylinder 10 and the first cylinder 19 are respectively set at the upper and lower ends of the first bracket 3 to drive the first bracket 3 to move, so that the first bracket 3 remains stable at the upper and lower ends during movement and avoids wobbling. At the same time, the third cylinder 9 is set on the side of the second cylinder 10 opposite to the first bracket 3. By driving the third cylinder 9 in the opposite direction, the second cylinder 10 and the first cylinder 19 are limited, making the overall movement of the first bracket 3 more stable. The first bracket 3 and the base 1 are both fixed structures.

[0045] The first support 3 has symmetrically arranged movable slots 7 on both sides. A first lead screw 8 is rotatably installed in each of the two movable slots 7. A first motor 17 is fixedly installed at the bottom of each movable slot 7, and the drive end of the first motor 17 is fixedly connected to the first lead screw 8. The two ends of the second support 11 are slidably inserted into the two movable slots 7, and the two first lead screws 8 are threaded through both ends of the second support 11. When adjusting the drilling position, the first motor 17 drives the first lead screw 8 to rotate through its drive end. The first lead screw 8 is threaded through both ends of the second support 11. The two first motors 17 on both sides cooperate with each other, effectively moving the second support 11 up and down.

[0046] A second lead screw 12 is rotatably mounted inside the second bracket 11. A second motor 13 is fixedly mounted at one end of the second bracket 11, and the drive end of the second motor 13 is fixedly connected to the second lead screw 12. A fixed shaft 22 is fixedly connected to one end of the housing 6. The fixed shaft 22 slides inside the second bracket 11, and the second lead screw 12 is threaded through the fixed shaft 22. When it is necessary to change the horizontal position of the drill bit 20, the second motor 13 drives the second lead screw 12 to rotate through its drive end. The rotation of the second lead screw 12 will drive the fixed shaft 22 to move horizontally, and then the fixed shaft 22 will drive the housing 6 to move, thereby changing the horizontal position of the housing 6 and drilling holes at different positions of the irregular bracket.

[0047] Multiple rollers 18 are symmetrically rotatably connected to both sides of the first bracket 3. The rollers 18 roll on the base 1. Limiting blocks 14 are provided on both sides of the upper end of the first bracket 3, and limiting grooves that cooperate with the limiting blocks 14 are provided on the fixed frame 2. The first bracket 3 moves by the rollers 18, which can reduce the friction during the movement of the first bracket 3 and facilitate the movement of the first bracket 3. The limiting blocks 14 move back and forth in the limiting grooves to limit the movement of the first bracket 3 and maintain stability.

[0048] Reference Figures 9-10Inside the housing 6, a second gear 36 and a first gear 38 are rotatably mounted and mesh with each other. A third motor 33 is fixedly connected inside the housing 6. The drive end of the third motor 33 is fixedly connected to the second gear 36. One end of the drill bit 20 has symmetrically arranged protrusions 15. The first gear 38 has a first slot that cooperates with the protrusions 15. A rotating ring 35 is rotatably connected to the housing 6. The rotating ring 35 has a second slot that cooperates with the protrusions 15. The drill bit 20 passes through both the first gear 38 and the rotating ring 35. The drill bit 20 is fixedly connected to the rotating ring 35 by a nut 34. The drill bit 20 is detachably connected to the housing 6. When drilling is required, the third motor 33 drives the second gear 36 to rotate through the drive end. The second gear 36 drives the drill bit 20 to rotate through the first gear 38, thereby drilling a hole in the surface of the irregular bracket. During installation, the drill bit 20 is directly passed through the rotating ring 35 and the first gear 38, and then the nut 34 is threaded onto the drill bit 20, so that the drill bit 20 is fixed relative to the rotating ring 35. The rotating ring 35 will rotate synchronously with the drill bit 20.

[0049] A method for processing an irregularly shaped support includes the following steps:

[0050] S1: The side of the irregular bracket is clamped into the slot 30 of the operating table 4. The position of the top block 5 is adjusted according to the drilling position so that the top block 5 is offset from the drilling position. The lifting mechanism on both sides adjusts the limiting mechanism on both sides respectively. The fourth cylinder 31 drives the second connecting plate 29 to move through the drive end. The second connecting plate 29 drives the linkage mechanism to move through the third air pipe 37, thereby changing the height position of the top block 5. The fifth cylinder inflates the three-way pipe 24 through the first air pipe 23. The three-way pipe 24 inflates the second air pipes 21 on both sides. The second air pipe 21 pushes the push shaft 16 to move through the third air pipe 37 and the fourth air pipe 25, so that the top block 5 connected to the end of the push shaft 16 is close to the surface of the irregular bracket. The four top blocks 5 adaptively approach the irregular bracket and clamp and fix it.

[0051] S2: Adjust the position of drill bit 20 on the vertical plane according to the drilling position. The first motor 17 drives the first lead screw 8 to rotate through the drive end. The rotating first lead screw 8 can change the height position of the second support 11. The second motor 13 drives the second lead screw 12 to rotate through the drive end. The second lead screw 12 drives the fixed shaft 22 to move horizontally relative to the second support 11, changing the horizontal position of the machine box 6 and drill bit 20.

[0052] S3: The third cylinder 9, the second cylinder 10, and the first cylinder 19 drive the first bracket 3 to approach the operating table 4, and the drill bit 20 to approach the irregular bracket.

[0053] S4: The third motor 33 inside the chassis 6 starts. The third motor 33 drives the second gear 36 to rotate through the drive end. The second gear 36 drives the first gear 15 to rotate. The first gear 15 drives the drill bit 20 to rotate. As the drill bit 20 rotates at high speed and the first bracket 3 moves closer to the operating table 4, holes can be drilled on the surface of the irregular bracket.

[0054] S5: Repeat S1-S4 to drill holes at different locations on the irregularly shaped bracket.

[0055] In this invention, unless otherwise explicitly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., should be interpreted broadly.

S2: Adjust the position of the drill bit (20) on the vertical plane according to the drilling position. The first motor (17) drives the first lead screw (8) to rotate through the drive end, changing the position of the machine box (6) and the drill bit (20); S3: The third cylinder (9), the second cylinder (10), and the first cylinder (19) drive the first support (3) to approach the operating table (4), and the drill bit (20) to approach the irregular support; S4: The third motor (33) inside the chassis (6) starts. As the drill bit (20) rotates at high speed and the first support (3) moves closer to the operating table (4), holes can be drilled on the surface of the irregular support. S5: Repeat S1-S4 to drill holes at different locations on the irregularly shaped bracket.
