Description

Technical Field

[0001] This invention relates to the field of laser grinding, specifically to a multi-station laser grinding equipment for automotive oil pans. Background Technology

[0002] Laser grinding technology boasts advantages such as high precision and high repeatability, enabling the fine processing of complex-shaped parts. Combined with auxiliary components (such as positioning rings and circular plates), it can ensure the precise positioning of parts before and after processing, reducing error accumulation. Through multi-station design, parallel processing of laser grinding can be achieved, significantly shortening the processing cycle of individual parts, reducing manual intervention, and thus improving the overall production line efficiency.

[0003] Patent CN217166934U, belonging to the field of automotive parts processing equipment technology, describes a multi-station laser grinding equipment for automotive parts. It includes a concave processing table, with an L-shaped support frame fixedly connected to the top of the table. A cylinder is mounted on the inner wall of the L-shaped support frame, and a T-shaped connecting block is fixedly connected to the output end of the cylinder. A laser grinding head is connected to the bottom of the T-shaped connecting block, and a positioning assembly is located below the laser grinding head. An L-shaped fixing frame is fixedly connected to the top of the concave processing table, and the other side of the L-shaped fixing frame is fixedly connected to the inner wall of the L-shaped support frame. The positioning assembly, composed of a circular fixing plate, a positioning plate, a positioning ring, a positioning groove, an adjusting screw, and a clamping plate, ensures that the fixing assembly can satisfy multiple clamping stations for fixing automotive parts. This improves processing efficiency for mass-produced automotive parts and enhances the overall performance of the equipment. However, the above-mentioned device is prone to unloading difficulties after processing, and requires manual unloading by workers, resulting in low work efficiency. Therefore, a multi-station automotive oil pan laser grinding equipment is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-station automotive oil pan laser grinding equipment to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multi-station automotive oil pan laser grinding equipment, comprising a body, a laser grinding machine disposed on the inner wall of the body, a clamping mechanism disposed on the inner wall of the body, a main shaft disposed at the bottom of the clamping mechanism, a gear one fixedly connected to the bottom end of the main shaft, an extension block fixedly connected to the inner wall of the body, an extension block two fixedly connected to the inner wall of the body, a unloading mechanism disposed on the front side of the body, a feeding mechanism disposed on the inner wall of the body, and a cleaning machine disposed on the inner wall of the body. The structure includes a gear two at the bottom of the unloading mechanism, a clamping mechanism comprising a clamping ring, a protective plate fixedly connected to the bottom surface of the clamping ring, a clamping plate slidably connected to the top surface of the protective plate, a clamping plate spring rod fixedly connected to the clamping plate, a movable block fixedly connected to the end of the clamping plate spring rod away from the clamping plate, the clamping ring fixedly connected to the top of the main shaft, the side of the clamping plate slidably connected to the inner wall of the clamping ring, the clamping plate in contact with the inner wall of the clamping ring, the bottom surface of the clamping plate in contact with the top surface of the protective plate, and the circumferential surface of the gear one engaging with the gear teeth. The circumferential surfaces of the two wheels mesh with each other. The extension block is located on the movement trajectory of the movable block, and the second extension block is located on the movement trajectory of the movable block. The car oil pan is placed between the clamping plate and the clamping ring. At this time, the spring will drive the clamping plate to clamp the workpiece between the clamping ring and the clamping plate. Then, the workpiece is subjected to laser grinding by a laser grinding machine. The pressure generated by the clamping spring rod achieves stable clamping of the workpiece, ensuring the processing accuracy of the equipment. After the operation is completed, the spindle is driven to rotate by an externally set motor. The spindle drives the clamping ring to rotate, the clamping ring drives the clamping spring rod to rotate, and the clamping spring rod drives the movable block to rotate. After the movable block rotates, it contacts the extension block. The extension block pushes the movable block away from the clamping plate through the arc surface, so that the movable block drives the clamping spring rod to move, and the clamping spring rod drives the clamping plate to move. This makes the clamping plate move away from the workpiece and compress the spring on the surface of the clamping spring rod. At this time, the workpiece clamped between the clamping plate and the clamping ring will fall off and be unloaded. This realizes automatic unloading of the workpiece after the equipment completes grinding, reducing the participation of human resources and improving work efficiency.

[0006] Preferably, the unloading mechanism includes an unloading plate shaft, a unloading plate rotatably connected to the circumferential surface of the unloading plate shaft, a drive plate movably connected to the rear side of the unloading plate, a reciprocating screw movably connected to the inner wall of the drive plate, the side of the unloading plate contacting the inner wall of the machine body, and the reciprocating screw rotatably connected to the inner wall of the machine body on its circumferential surface. The feeding mechanism includes a feeding bin, a feeding trough fixedly connected to the inner wall of the feeding bin, a feeding plate fixedly connected to the end of the feeding trough away from the feeding bin, a feeding shaft rotatably connected to the inner wall of the feeding bin, and a fixed connection at the bottom of the feeding bin. The feeding plate is rotatably connected to the circumferential surface of the feeding shaft, attached to the inner wall of the machine body. When the equipment completes grinding, the clamping ring drives the movable block to rotate. When the movable block rotates to the working range of the unloading mechanism, the movable block slides outward along the outer surface of the extension block two. The movable block drives the spring inside the clamping plate spring rod to compress, and the clamping plate spring rod drives the clamping plate to slide outward, opening the clamping plate. The workpiece falls onto the unloading plate along the unloading port opened on the protective plate, completing the automated unloading of the ground workpiece. At this time, the main shaft rotates, driving gear one to rotate, gear one to rotate, and gear two to rotate, driving the reciprocating... When the lead screw rotates, the reciprocating lead screw drives the drive plate to move up and down reciprocally. The drive plate drives the unloading plate to slide back and forth along the circumference of the unloading plate's rotating shaft, shaking off the unloaded workpieces. This prevents the workpieces from accumulating on the unloading plate due to excessive surface friction, which would affect the working efficiency of subsequent equipment. After unloading is completed, the clamping ring continues to rotate, driving the clamping spring rod to rotate. The clamping spring rod drives the movable block to rotate. When the movable block rotates to the working range of the extension block, the movable block moves outward along the circular surface of the extension block. The forward movement of the movable block drives the clamping spring rod to... The outward movement of the clamping plate causes the clamping plate to slide outward. Simultaneously, the movable block presses against the feeding plate and causes it to rotate counterclockwise along the inclined surface of the movable block on the circumference of the feeding shaft. This stretches the spring connecting the feeding plate and the feeding bin. The rotation of the feeding plate pours the workpiece stored in the feeding groove into the clamping ring. When the clamping ring rotates away from the working range of the extension block, the clamping plate spring returns and causes the clamping plate to slide inward. This achieves the automatic clamping function of the equipment before grinding the workpiece, making reasonable use of the multi-station characteristics of the equipment and improving work efficiency.

[0007] Preferably, the cleaning mechanism includes a push plate, a reciprocating screw two is movably connected to the inner wall of the push plate, a bevel gear two is fixedly connected to the circumferential surface of the reciprocating screw two, a movable plate is rotatably connected to the bottom of the protective plate, a fixed rod is rotatably connected to the movable plate via a torsion spring, a rotating rod is rotatably connected to the inner wall of the machine body via a connecting rod, a bevel gear one is fixedly connected to the bottom of the rotating rod via a connecting rod, the inner wall of the push plate is slidably connected to the inner wall of the machine body, the rotating rod is located on the movement trajectory of the movable block, the bevel gear one meshes with the bevel gear two, the equipment starts, the motor drives the main shaft to rotate, the main shaft drives the clamping ring to rotate, the clamping ring drives the movable block to rotate, and the movable block carries... The rotating rod rotates, which drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate, which in turn drives the second reciprocating screw to rotate. The second reciprocating screw drives the push plate to slide back and forth at the bottom of the machine body. Waste ports are opened on both the left and right sides of the machine body. The reciprocating sliding of the push plate pushes the waste material after grinding out of the equipment. This allows the waste material remaining on the worktable to be pushed out by the push plate while the equipment is running. At the same time, the rotatable movable plate discharges the waste material remaining on the clamping ring through the movable plate. This completes the cleaning of the waste material after grinding after the equipment has worked, reduces the impact of residual waste material on the grinding process, ensures the processing accuracy of the equipment, and improves work efficiency.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This multi-station automotive oil pan laser grinding equipment achieves automatic workpiece unloading after grinding by coordinating the operation of the clamping ring, protective plate, clamping plate, movable block, clamping plate spring rod, and extension block. This reduces the need for manpower and improves work efficiency. The clamping plate, which can slide on the inner wall of the clamping ring, achieves stable clamping of the workpiece through the pressure generated by the clamping plate spring rod, ensuring the processing accuracy of the equipment.

[0009] 2. This multi-station automotive oil pan laser grinding equipment, through the coordinated operation of the movable block, feeding bin, feeding spring, feeding shaft, feeding plate, unloading plate, drive plate, reciprocating screw one, unloading plate shaft, and extension block two, realizes the discharge of workpieces that have been unloaded from the equipment, preventing excessive accumulation of workpieces on the inner wall of the equipment from affecting the processing accuracy. The rotatable feeding plate is squeezed and rotated by the movable block, realizing the automatic clamping function of the equipment before grinding the workpiece. It makes reasonable use of the multi-station characteristics of the equipment and improves work efficiency.

[0010] 3. The modified multi-station automotive oil pan laser grinding equipment, through the coordinated operation of the push plate, movable plate, torsion spring shaft, rotating rod, bevel gear one, bevel gear two, and reciprocating screw two, enables the push plate to push out residual waste on the worktable while the equipment is running. At the same time, the movable block discharges residual waste on the clamping plate ring through the movable plate, completing the cleaning of waste after grinding after the equipment has finished working. This reduces the impact of residual waste on the grinding process, ensures the processing accuracy of the equipment, and improves work efficiency. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figures 1-7One embodiment of the present invention is: a multi-station automotive oil pan laser grinding equipment, comprising a body 1, a laser grinding machine 2 disposed on the inner wall of the body 1, a clamping mechanism 3 disposed on the inner wall of the body 1, a main shaft 8 disposed at the bottom of the clamping mechanism 3, a gear 9 fixedly connected to the bottom end of the main shaft 8, an extension block 4 fixedly connected to the inner wall of the body 1, an extension block 11 fixedly connected to the inner wall of the body 1, a discharge mechanism 5 disposed on the front side of the body 1, a feeding mechanism 6 disposed on the inner wall of the body 1, a cleaning mechanism 7 disposed on the inner wall of the body 1, a gear 10 fixedly connected to the bottom of the discharge mechanism 5, and a clamping ring 301 disposed on the clamping mechanism 3, a protective plate 302 fixedly connected to the bottom surface of the clamping ring 301, a clamping plate 303 slidably connected to the top surface of the protective plate 302, and a clamping plate spring rod 305 fixedly connected to the clamping plate 303. The sliding clamping plate 303 on the inner wall of 301, through the pressure generated by the clamping plate spring rod 305, achieves stable clamping of the workpiece, ensuring the processing accuracy of the equipment. The end of the clamping plate spring rod 305 away from the clamping plate 303 is fixedly connected to the movable block 304. The clamping plate ring 301 is fixedly connected to the top of the spindle 8. The side of the clamping plate 303 is slidably connected to the inner wall of the clamping plate ring 301. The clamping plate 303 and the inner wall of the clamping plate ring 301 are in contact with each other. The bottom surface of the clamping plate 303 is in contact with the top surface of the protective plate 302. The circumferential surface of gear 19 and gear 210 mesh with each other. The extension block 4 is located on the movement trajectory of the movable block 304, and the extension block 21 is located on the movement trajectory of the movable block 304. This realizes automatic unloading of the workpiece after the equipment completes grinding, reducing the participation of human resources and improving work efficiency.

[0015] The unloading mechanism 5 includes an unloading plate shaft 504, with an unloading plate 501 rotatably connected to the circumferential surface of the shaft 504. An active plate 502 is movably connected to the rear side of the unloading plate 501, and a reciprocating screw 503 is movably connected to the inner wall of the active plate 502. The side of the unloading plate 501 contacts the inner wall of the machine body 1, and the reciprocating screw 503 is rotatably connected to the inner wall of the machine body 1. This mechanism facilitates the discharge of unloaded workpieces from the equipment, preventing excessive accumulation of workpieces on the inner wall and thus affecting the processing accuracy of the equipment. The feeding mechanism 6 includes a feeding bin 60. 1. A feeding trough 602 is fixedly connected to the inner wall of the feeding bin 601. A feeding plate 604 is fixedly connected to the end of the feeding trough 602 away from the feeding bin 601. A feeding shaft 603 is rotatably connected to the inner wall of the feeding bin 601. The bottom of the feeding bin 601 is fixedly connected to the inner wall of the machine body 1. The feeding plate 604 is rotatably connected to the circumferential surface of the feeding shaft 603. The rotatable feeding plate 604 is squeezed and rotated by the movable block 304, realizing the automatic clamping function of the equipment before grinding the workpiece. It makes reasonable use of the multi-station characteristics of the equipment and improves the work efficiency.

[0016] Working principle: The car oil pan is placed between clamping plate 303 and clamping ring 301. The spring then drives clamping plate 303 to hold the workpiece between clamping ring 301 and clamping plate 303. Laser grinding is then performed on the workpiece using laser grinding machine 2. The pressure generated by the clamping spring rod 305 ensures stable clamping of the workpiece, guaranteeing the processing accuracy of the equipment. After the operation is completed, an externally installed motor drives the spindle 8 to rotate. The spindle 8 drives the clamping ring 301 to rotate, which in turn drives the clamping spring rod 305 to rotate. The clamping spring rod 305 then drives the movable... When block 304 rotates, the movable block 304 comes into contact with the extension block 4. The extension block 4 pushes the movable block 304 away from the clamping plate 303 through the arc surface, so that the movable block 304 drives the clamping plate spring rod 305 to move. The clamping plate spring rod 305 drives the clamping plate 303 to move, thereby moving the clamping plate 303 away from the workpiece and compressing the spring on the surface of the clamping plate spring rod 305. At this time, the workpiece clamped between the clamping plate 303 and the clamping plate ring 301 will fall off and be unloaded. This realizes the automatic unloading of the workpiece after the equipment finishes grinding, reducing the participation of human resources and improving work efficiency. When the equipment completes grinding, the clamping ring 301 drives the movable block 304 to rotate. When the movable block 304 rotates to the working range of the unloading mechanism 5, the movable block 304 slides outward along the outer surface of the extension block 11. The movable block 304 drives the spring inside the clamping spring rod 305 to compress, and the clamping spring rod 305 drives the clamping plate 303 to slide outward, opening the clamping plate 303. The workpiece falls onto the unloading plate 501 through the unloading port on the protective plate 302, completing the automated unloading of the ground workpiece. At this time, the main... The rotation of shaft 8 drives gear 9 to rotate, which in turn drives gear 10 to rotate. Gear 10 then drives reciprocating screw 503 to rotate, which in turn drives drive plate 502 to reciprocate up and down. Drive plate 502 drives unloading plate 501 to slide reciprocally along the circumference of unloading plate shaft 504, shaking off the unloaded workpieces and preventing them from accumulating on unloading plate 501 due to excessive friction, which would affect the working effect of subsequent equipment. After unloading is completed, clamping ring 301 continues to... As the clamping ring 301 continues to rotate, it drives the clamping spring rod 305 to rotate, which in turn drives the movable block 304 to rotate. When the movable block 304 rotates to the working range of the extension block 4, it moves outward along the circular surface of the extension block 4. The forward movement of the movable block 304 drives the clamping spring rod 305 to move outward, which in turn drives the clamping plate 303 to slide outward. At the same time as the movable block 304 moves outward, it presses the feeding plate 604 and drives the feeding plate 604 to move along the movable block. The inclined surface of 304 rotates counterclockwise on the circumferential surface of the feeding shaft 603, stretching the spring connecting the feeding plate 604 and the feeding bin 601. The feeding plate 604 rotates to pour the workpiece stored in the feeding groove 602 into the clamping ring 301. When the clamping ring 301 rotates away from the working range of the extension block 4, the clamping spring rod 305 rebounds and drives the clamping plate 303 to slide inward, realizing the automatic clamping function of the equipment before grinding the workpiece. It makes reasonable use of the multi-station characteristics of the equipment and improves work efficiency.

[0017] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 7 includes a push plate 701, a reciprocating lead screw 707 movably connected to the inner wall of the push plate 701, a bevel gear 706 fixedly connected to the circumferential surface of the reciprocating lead screw 707, a movable plate 702 rotatably connected to the bottom of the protective plate 302, and a fixed rod 703 rotatably connected to the movable plate 702 via a torsion spring, thereby realizing the ejection of residual waste on the workbench by the push plate 701 while the equipment is running. A rotating rod 70 is rotatably connected to the inner wall of the machine body 1 via a connecting rod. 4. The bottom of the rotating rod 704 is fixedly connected to the first bevel gear 705 via a connecting rod. The inner wall of the push plate 701 is slidably connected to the inner wall of the machine body 1. The rotating rod 704 is located on the movement trajectory of the movable block 304. The first bevel gear 705 meshes with the second bevel gear 706. The movable block 304 can rotate so that the residual waste on the clamping ring 301 is discharged from the movable plate 702. This completes the cleaning of the waste after grinding after the equipment has been working, reduces the impact of residual waste on the grinding process of the device, ensures the processing accuracy of the equipment, and improves the work efficiency.

[0018] Working principle: When the equipment starts, the motor drives the main shaft 8 to rotate, the main shaft 8 drives the clamping ring 301 to rotate, the clamping ring 301 drives the movable block 304 to rotate, the movable block 304 drives the rotating rod 704 to rotate, the rotating rod 704 drives the first bevel gear 705 to rotate, the first bevel gear 705 drives the second bevel gear 706 to rotate, the second bevel gear 706 drives the second reciprocating screw 707 to rotate, the second reciprocating screw 707 drives the push plate 701 to slide back and forth at the bottom of the machine body 1. There are waste ports on both the left and right sides of the machine body 1. The reciprocating sliding of the push plate 701 pushes the waste material after grinding out of the equipment. This realizes that while the equipment is running, the waste material remaining on the worktable is pushed out by the push plate 701. At the same time, the rotatable movable plate 702 discharges the waste material remaining on the clamping ring 301 through the movable plate 702. This completes the cleaning of the waste material after grinding after the equipment has worked, reduces the impact of residual waste material on the grinding process of the device, ensures the processing accuracy of the equipment, and improves work efficiency.
