Description

Technical Field

[0001] This invention belongs to the field of gate processing technology, and in particular relates to a vertical laser welding gate device and method. Background Technology

[0002] In the field of gate plate manufacturing, laser welding is one of the commonly used processing methods. It usually requires specialized equipment to complete the positioning and welding operations of the gate plate. Such equipment is generally equipped with a platform for placing the gate plate and a mechanical structure for performing the welding operation. Some equipment is also equipped with simple fixing components to ensure the stability of the gate plate during the welding process. At the same time, a basic unloading structure is designed to remove the welded gate plate from the equipment.

[0003] However, in practical applications, the fixing components of existing equipment are mostly manually adjustable, allowing only one gate to be fixed at a time. This involves numerous steps, is time-consuming, and fails to meet the needs of batch processing. After welding, most equipment requires manual removal of the gate from the platform. At this time, the gate is hot, easily causing burns to operators, and manual removal is slow, affecting the overall processing progress. In addition, welding slag easily adheres to the gate surface or mixes within the gate. Existing equipment lacks a dedicated separation structure, requiring additional subsequent processing, increasing workload. Furthermore, the feeding channel of some equipment is prone to gate accumulation and blockage during use, requiring frequent shutdowns for cleaning and causing processing interruptions. Therefore, a vertical laser welding gate device and method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical laser welding gate device and method, which can improve the gate fixing efficiency, avoid burns to operators, separate welding slag from the gate, prevent material blockage, ensure smooth processing, and solve existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A vertical laser welding gate device includes: a chassis, a mounting plate fixedly installed in the middle of the chassis, and a three-axis welding robot fixedly installed on the surface of the mounting plate;

[0007] Two guide rails are fixed to the surface of the mounting plate. A middle plate is slidably connected between the two guide rails. Side plates are hinged to both sides of the middle plate. The surface of the side plates is flush with the bottom surface of the middle plate. A sealed cavity is provided in the middle of the middle plate. Multiple fixing mechanisms for fixing the gate are provided on both sides of the middle plate.

[0008] The fixing mechanism includes two sets of fixing rods and a second piston cylinder. Both sets of fixing rods are fixed to one side of the middle plate. An arc-shaped fixing plate is fixedly connected to one end of each fixing rod. A clamping plate is slidably connected between the two sets of fixing rods. The clamping plate is arc-shaped and works in conjunction with the fixing plate. The second piston cylinder is fixed to one side of the middle plate and communicates with the cavity. A second piston rod slides through one end of the second piston cylinder and is fixed to the clamping plate.

[0009] A drive mechanism is provided at one end of the intermediate plate to drive the second piston rod to move.

[0010] Furthermore, the drive mechanism includes a fixed frame and a first piston cylinder. The fixed frame is fixed to one end of the intermediate plate, and a cylinder is fixedly connected to one end of the fixed frame. The first piston cylinder is fixed to one end of the intermediate plate and located in the cavity. A first piston rod is slidably connected to one end of the first piston cylinder, and the output end of the cylinder is fixed to the first piston rod.

[0011] Furthermore, the surface of the mounting plate has two through discharge ports, and the two side plates can rotate through the discharge ports. A discharge component is provided between the fixing plate and the clamping plate for discharge. The discharge component includes two leakage ports, which are located below the fixing plate and the clamping plate respectively. The two leakage ports are respectively located on the opposite side of the middle plate and the side plate. The fixing plate and the clamping plate and the two leakage ports form a support platform for supporting the gate. The width of the support platform below the clamping plate is smaller than the radius of the gate so that the gate can slide freely when the side plate rotates.

[0012] Furthermore, a guide box is fixedly connected to the bottom of the mounting plate to guide the falling gate, and the bottom of the guide box is inclined.

[0013] Furthermore, the bottom of the feed box is provided with multiple slag outlets for impurities to fall off.

[0014] Furthermore, the bottom of the mounting plate is also provided with a support mechanism for supporting the side plate. The support mechanism includes at least two sets of rotating shafts, all of which rotate at the bottom of the mounting plate. A support rod is fixedly connected to one side of each rotating shaft. The support rod can rotate to support the side plate or detach from the support of the side plate.

[0015] Furthermore, each of the rotating shafts is fixedly connected to a worm gear at its bottom, and a motor is fixedly connected to the bottom of the mounting plate. One end of the motor output shaft is fixedly connected to a worm, which meshes with the worm gear. The worm is connected to the bottom of the mounting plate through a bearing seat.

[0016] Furthermore, a fixing plate is fixedly connected to the bottom surface of the guide box, a one-way bearing is fixedly connected to the circumference of the worm gear, a drive disk is fixed to the outer ring of the one-way bearing, a plurality of arc-shaped wedges are fixedly connected to one side of the drive disk, a bracket is fixedly connected to the bottom of the mounting plate, a mounting shaft is fixedly connected to one side of the bracket, a swing rod is rotatably connected to the circumference of the mounting shaft, the top of the swing rod is located on one side of the wedge and drives it to rotate through the wedge, and a counterweight is fixedly connected to the bottom of the swing rod, which collides with the fixing plate when it is reset on one side of the fixing plate.

[0017] Furthermore, each of the support rods has a support sleeve rotatably connected to one end, and one end of the support sleeve is tapered.

[0018] This invention also proposes a method for using a vertical laser welding gate device, comprising the following steps:

[0019] S1: When in use, pull out the middle plate, then place the gate plate to be processed between the fixed plate and the clamping plate, then reset and lock it, start the cylinder, the cylinder drives the first piston rod to rotate, the first piston rod moves in the first piston cylinder, and then inflates the cavity. At the same time, the air pushes the second piston rod to move through the second piston cylinder, and then pushes the clamping plate to move, so as to cooperate with the fixed plate to clamp and fix the gate plate. Multiple gate plates can be fixed at the same time, and the operation is convenient and quick.

[0020] S2: Multiple gate plates are welded separately by a three-axis welding robot. After welding, the motor is started, and the motor drives the worm gear to rotate. The worm gear drives the support rod to rotate through the worm wheel, so that the support rod is disengaged from the support of the side plate. After the side plate falls, the gate plate falls along the material discharge port and the gap between the fixing plate and the side plate, which enables the gate plates to fall quickly at the same time, avoiding manual picking and improving processing efficiency.

[0021] S3: After material discharge, the side plate can be lifted by resetting the support rod, and then the middle plate can be pulled out to add material again for processing;

[0022] S4: When the worm rotates, the one-way bearing drives the drive plate to rotate, and the drive plate drives the wedge to rotate, which in turn pushes the top of the swing rod so that the counterweight moves away from the fixed plate. After the wedge disengages from the swing rod, the counterweight can reset under its own weight and then collide with the fixed plate, causing the guide box to vibrate, which facilitates material feeding and also facilitates the sliding of welding slag through the slag discharge port.

[0023] The embodiments of the present invention have the following beneficial effects:

[0024] In this invention, by setting a fixing mechanism consisting of a fixing rod, a fixing plate, a clamping plate and a second piston cylinder on both sides of the middle plate, and cooperating with the driving mechanism to inflate the cavity and push the second piston rod to move, multiple gates can be clamped and fixed at the same time without having to operate them one by one, which greatly shortens the fixing time and improves the gate fixing efficiency.

[0025] In this invention, the surface of the mounting plate is provided with a discharge port, the side plate can rotate through the discharge port, and the fixing plate and clamping plate are provided with a leakage port. After welding, the side plate rotates downward, and the gate can automatically slide down along the leakage port and gap, without the need for manual picking up, avoiding burns to the operator caused by the high temperature gate, and at the same time speeding up the removal speed of the gate after welding.

[0026] In this invention, a guide box is provided at the bottom of the mounting plate, and multiple slag discharge ports are opened at the bottom of the guide box. The welding slag falling with the gate can be discharged separately through the slag discharge ports, realizing the automatic separation of welding slag from the gate, eliminating the need for subsequent additional separation operations, and reducing processing steps and workload.

[0027] In this invention, a motor drives a worm gear to rotate, and the worm gear, in conjunction with a worm wheel, drives a rotating shaft and a support rod to rotate, thereby supporting or disengaging the side plate. At the same time, when the worm gear rotates, it drives a drive disc and a wedge to rotate through a one-way bearing, pushing a swing rod to reset the counterweight and collide with the fixed plate, causing the guide box to vibrate, thus preventing the gate from blocking the guide box and ensuring smooth material feeding.

[0028] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] 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.

[0039] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0040] In one embodiment, please refer to Figures 1-7 As shown, this embodiment provides a vertical laser welding gate device, including: a chassis 1, an mounting plate 2 fixedly installed in the middle of the chassis 1, and a three-axis welding robot 3 fixedly installed on the surface of the mounting plate 2. The three-axis welding robot 3 is a translational type, which is composed of three linear motion modules that are perpendicularly combined with each other. This is the prior art and is used for welding gates, so it will not be described in detail here.

[0041] Two guide rails 6 are fixed to the surface of the mounting plate 2. A middle plate 7 is slidably connected between the two guide rails 6. The surface of the middle plate 7 can be threaded with a set screw that abuts against the guide rails 6 for fixing the middle plate 7. Side plates 8 are hinged to both sides of the middle plate 7. The surface of the side plates 8 is flush with the bottom surface of the middle plate 7. The gate can be placed between the middle plate 7 and the side plates 8. The gate can be placed easily by pulling out the middle plate 7. A sealed cavity 11 is provided in the middle of the middle plate 7. Multiple fixing mechanisms for fixing the gate are provided on both sides of the middle plate 7.

[0042] The fixing mechanism includes two sets of fixing rods 15 and a second piston cylinder 19. Both sets of fixing rods 15 are fixed to one side of the intermediate plate 7. An arc-shaped fixing plate 16 is fixedly connected to one end of each fixing rod 15. A clamping plate 27 is slidably connected between the two sets of fixing rods 15. The clamping plate 27 is arc-shaped and works in conjunction with the fixing plate 16. The second piston cylinder 19 is fixed to one side of the intermediate plate 7 and communicates with the cavity 11. A second piston rod 20 slides through one end of the second piston cylinder 19. The second piston rod 20 is fixed to the clamping plate 27. Air passes through the second piston cylinder 19 to push the second piston rod 20 to move, which in turn pushes the clamping plate 27 to move, thereby cooperating with the fixing plate 16 to clamp and fix the gate. Multiple gates can be fixed at the same time. The operation is convenient and quick, and the fixing efficiency is improved.

[0043] A drive mechanism is located at one end of the intermediate plate 7 to drive the second piston rod 20 to move.

[0044] In this invention, the driving mechanism includes a fixed frame 10 and a first piston cylinder 12. The fixed frame 10 is fixed to one end of the intermediate plate 7, and a cylinder 14 is fixedly connected to one end of the fixed frame 10. The first piston cylinder 12 is fixed to one end of the intermediate plate 7 and located in the cavity 11. A first piston rod 13 is slidably connected to one end of the first piston cylinder 12. The output end of the cylinder 14 is fixed to the first piston rod 13. When the cylinder 14 is activated, the cylinder 14 drives the first piston rod 13 to rotate. The first piston rod 13 moves in the first piston cylinder 12, thereby inflating the cavity 11, which in turn enables the second piston rod 20 to drive the clamping plate 27 to move.

[0045] In another embodiment: refer to Appendix Figures 1-7 A vertical laser welding gate device.

[0046] In this invention, the surface of the mounting plate 2 has two through discharge ports 9. The two side plates 8 can rotate through the discharge ports 9. Discharge components are provided between the fixing plate 16 and the clamping plate 27 for discharging materials. The discharge components include two discharge ports 17, which are located below the fixing plate 16 and the clamping plate 27, respectively. The two discharge ports 17 are respectively located on the opposite side of the middle plate 7 and the side plate 8. The fixing plate 16 and the clamping plate 27 and the two discharge ports 17 form a support platform 18 for supporting the gate. The width of the support platform 18 below the clamping plate 27 is smaller than the radius of the gate, so that the gate can slide freely when the side plate 8 rotates. The side plate 8 can rotate downward. After rotation, the gate falls along the discharge ports 17 and the gap between the fixing plate 16 and the side plate 8, thereby enabling the gate to fall quickly and simultaneously, avoiding manual picking, improving processing efficiency and safety of use, and preventing burns.

[0047] In particular, a guide box 4 is fixedly connected to the bottom of the mounting plate 2 to guide the falling gate. The bottom of the guide box 4 is inclined, and the falling gate can slide downwards at the bottom of the guide box 4, thus facilitating collection.

[0048] It should be noted that the bottom of the feed box 4 is provided with multiple slag discharge ports 5 for impurities to fall down. The welding slag falling with the gate can fall down through the slag discharge ports 5 and be collected in a concentrated manner, so as to avoid it from being concentrated together with the gate.

[0049] In this invention, the bottom of the mounting plate 2 is also provided with a support mechanism for supporting the side plate 8. The support mechanism includes at least two sets of rotating shafts 23, all of which rotate at the bottom of the mounting plate 2. A support rod 25 is fixedly connected to one side of each rotating shaft 23. A support sleeve 26 is rotatably connected to one end of each support rod 25. One end of the support sleeve 26 is tapered. When the support rod 25 is located below the side plate 8, it can support the side plate 8. At the same time, the top of the support sleeve 26 is flush with the surface of the mounting plate 2, which facilitates the side plate 8 to move with the middle plate 7. The support rod 25 can rotate to support the side plate 8 or disengage from supporting the side plate 8.

[0050] In particular, a worm gear 24 is fixedly connected to the bottom of the rotating shaft 23, and a motor 21 is fixedly connected to the bottom of the mounting plate 2. A worm 22 is fixedly connected to one end of the output shaft of the motor 21. The worm 22 meshes with the worm gear 24. The worm 22 is connected to the bottom of the mounting plate 2 through a bearing seat. When the motor 21 is started, the motor 21 can drive the worm 22 to rotate. The worm 22 drives the support rod 25 to rotate through the worm gear 24, thereby realizing the support of the side plate 8 or the detachment from the support of the side plate 8.

[0051] In this invention, a fixing plate 35 is fixedly connected to the bottom surface of the guide box 4, a one-way bearing 28 is fixedly connected to the circumference of the worm gear 22, a drive disk 29 is fixed to the outer ring of the one-way bearing 28, a plurality of arc-shaped wedges 30 are fixedly connected to one side of the drive disk 29, a bracket 31 is fixedly connected to the bottom of the mounting plate 2, a mounting shaft 32 is fixedly connected to one side of the bracket 31, a swing rod 33 is rotatably connected to the circumference of the mounting shaft 32, the top of the swing rod 33 is located on one side of the wedges 30 and is driven to rotate by the wedges 30, and the swing rod 33... A counterweight 34 is fixedly connected to the bottom. When the counterweight 34 is located on one side of the fixed plate 35, it collides with the fixed plate 35. When the worm gear 22 rotates, the one-way bearing 28 drives the drive disk 29 and the wedge block 30 to rotate, thereby pushing the top of the swing rod 33 so that the counterweight 34 moves away from the fixed plate 35. After the wedge block 30 disengages from the swing rod 33, the counterweight 34 can reset under its own weight and then collide with the fixed plate 35, causing the guide box 4 to vibrate, which facilitates material feeding and also facilitates the sliding of welding slag and discharge through the slag outlet 5.

[0052] This invention also proposes a method for using a vertical laser welding gate device, comprising the following steps:

[0053] S1: When in use, pull out the middle plate 7, then place the gate plate to be processed between the fixing plate 16 and the clamping plate 27, then reset and lock it, start the cylinder 14, the cylinder 14 drives the first piston rod 13 to rotate, the first piston rod 13 moves in the first piston cylinder 12, and then inflates the cavity 11. At the same time, the air pushes the second piston rod 20 to move through the second piston cylinder 19, and then pushes the clamping plate 27 to move, so as to cooperate with the fixing plate 16 to clamp and fix the gate plate. Multiple gate plates can be fixed at the same time, and the operation is convenient and quick.

[0054] S2: The three-axis welding robot 3 welds multiple gate plates separately. After welding, the motor 21 is started. The motor 21 drives the worm gear 22 to rotate. The worm gear 22 drives the support rod 25 to rotate through the worm wheel 24, so that the support rod 25 is disengaged from the support of the side plate 8. After the side plate 8 falls, the gate plate falls along the material discharge port 17 and the gap between the fixing plate 16 and the side plate 8, so that the gate plate can fall quickly at the same time, avoiding manual picking and improving processing efficiency.

[0055] S3: After material discharge, the side plate 8 can be lifted by resetting the support rod 25, and then the middle plate 7 can be pulled out to add material again for processing;

[0056] S4: When the worm gear 22 rotates, the one-way bearing 28 drives the drive disk 29 to rotate. The drive disk 29 drives the wedge block 30 to rotate, which in turn pushes the top of the swing rod 33 so that the counterweight block 34 moves away from the fixed plate 35. After the wedge block 30 disengages from the swing rod 33, the counterweight block 34 can reset under its own weight and then collide with the fixed plate 35, causing the guide box 4 to vibrate, which facilitates material feeding and also facilitates the sliding of welding slag through the slag discharge port 5.

After the side plate (8) falls, the gate plate falls along the material discharge port (17) and the gap between the fixing plate (16) and the side plate (8), so that the gate plate can fall quickly at the same time, avoiding manual picking and improving processing efficiency. S3: After material discharge, the side plate (8) can be lifted by resetting the support rod (25), and then the middle plate (7) can be pulled out to add material again for processing; S4: When the worm (22) rotates, the one-way bearing (28) drives the drive disk (29) to rotate. The drive disk (29) drives the wedge (30) to rotate, which in turn pushes the top of the swing rod (33) so that the counterweight (34) moves away from the fixed plate (35). After the wedge (30) disengages from the swing rod (33), the counterweight (34) can reset under its own weight and collide with the fixed plate (35), causing the guide box (4) to vibrate, which facilitates material feeding and also facilitates the sliding of welding slag through the slag outlet (5) for discharge.
