Description

Technical Field

[0001] This utility model relates to the field of plate welding technology, and in particular to a welding plate positioner. Background Technology

[0002] A search revealed a Chinese patent with authorization number CN210209194U, which discloses a welding plate displacement device for a welding machine. The device includes a welding plate structure with a displacement structure above it. A support column is connected to the middle of one side of the welding plate structure away from the displacement structure. A base plate is connected to the end of the support column away from the welding plate structure. A drive motor is fixedly connected inside the end of the support column away from the base plate. An auxiliary support plate is fixedly connected to the outer wall of the support column at the drive motor end. The beneficial effects of this invention are: rotating the handle drives the adjusting screw to rotate, thereby moving the clamping plate and achieving a clamping and fixing function. This allows for the fixing of parts or plates that need to be welded, making welding more convenient. The movable shaft allows for smoother rotation of the adjusting screw. The slider allows for the movement of the moving plate. The limiting post prevents the linkage structure from shifting during movement, thus avoiding obstruction of the clamping plate's movement.

[0003] The welding plate positioning device for welding machines in the aforementioned patent has the following shortcomings: it cannot adjust the height of the plate, cannot adapt to the height of different users, has poor adaptability, operators may need to weld in an unnatural posture, which increases physical fatigue and discomfort, is inconvenient to operate, requires more time to perform welding operations, and leads to reduced work efficiency. Therefore, it is necessary to design a welding plate positioner to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a welded plate positioner.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding plate positioner includes a base plate. A first motor is fixedly connected to the top of the base plate. A first bevel gear is fixedly connected to the output end of the first motor. The first bevel gear meshes with a second bevel gear. A first drive screw is fixedly connected to the top of the second bevel gear. A first screw nut is fitted onto the first drive screw and is adapted to the first drive screw. A circular tube is fixedly connected to the outer wall of the first screw nut. A first frustum is fixedly connected to the top of the circular tube. The first frustum has four arc-shaped grooves. Each of the four grooves is equipped with a sliding rod, which is slidably connected to a first truncated cone. A slider is fixedly connected to the top of each of the four sliding rods. A second truncated cone is located on the top of the first truncated cone, and four sliding grooves are formed on the second truncated cone. The sliders are disposed within these grooves and are slidably connected to the second truncated cone. A clamping plate is fixedly connected to the top of each of the four sliders. Support plates are fixedly connected to the tops of both ends of the base plate. A sleeve plate is fixedly connected to the outer wall of the support plate. A limit rod is slidably connected to the inner wall of the sleeve plate, and the limit rod is fixedly connected to the outer wall of the second truncated cone. Due to the use of the upper... The technology involves moving the clamping plate closer to the plate during the lifting process and moving it away during the lowering process. After the plate is clamped and fixed, continuing to rotate the output of the first motor allows the plate to rise until it reaches a suitable height for the user. This allows the user to weld in a natural posture, reducing fatigue and discomfort, and improving operation efficiency. After the second platform descends to its initial position, continuing to rotate the output of the first motor reverses the second platform, moving the clamping plate away from the plate, allowing the welded plate to be removed. This effectively solves the problems mentioned in the background technology, such as the inability of most existing devices to adjust the plate height, poor adaptability, and the need for operators to weld in unnatural postures, increasing fatigue and discomfort, and requiring more time for welding, thus reducing work efficiency. This technology achieves simple operation, easy clamping and unclamping of the plate, easy adjustment of the plate height, and adaptability to users of different heights.

[0007] As a further embodiment of this utility model, a limiting ring is fixedly connected to the bottom outer wall of the first drive screw. The first drive screw and the limiting ring are both fitted with the same fixing frame. The fixing frame is fixedly connected to the base plate. When the first drive screw rotates, it will cause the limiting ring to rotate. The limiting ring will rotate within the fixing frame, thereby ensuring the stability of the first drive screw when it rotates.

[0008] As a further embodiment of this utility model, four movable wheels are fixedly connected to the bottom of the base plate.

[0009] As a further embodiment of this utility model, a base is provided at the bottom of the base plate, and the movable wheel contacts the top of the base.

[0010] As a further embodiment of this utility model, side plates are fixedly connected to the top of both ends of the base. A third bevel gear is provided on one side of one of the side plates. The third bevel gear is meshed with a fourth bevel gear. A support plate is provided on the top of the fourth bevel gear. The support plate is fixedly connected to the side plate. A second motor is fixedly connected to the top of the support plate. The output end of the second motor is fixedly connected to the fourth bevel gear.

[0011] As a further embodiment of this utility model, a second drive screw is fixedly connected to one side of the third bevel gear. Both ends of the second drive screw are fitted with bearing seats. The second drive screw is fixedly connected to the inner wall of the inner ring of the bearing on the bearing seat. A second screw nut is fitted onto the second drive screw. The second screw nut passes through the base plate and is fixedly connected to the base plate.

[0012] As a further embodiment of this utility model, guide rods are provided at both ends of the base plate, the base plate is slidably connected to the guide rods, and the guide rods are fixedly connected to the side plates. The base plate moves along the guide rods when it moves, thereby ensuring the stability of the base plate when it moves.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention addresses the problem that existing devices often fail to adjust the height of the plate, making them unsuitable for different user heights. These devices require unnatural welding postures, increasing fatigue and discomfort, and reducing the time spent on welding, thus improving efficiency. The invention simplifies operation, allowing for easy clamping and un-clamping of the plate, and facilitates height adjustment for users of varying heights. The invention achieves a simpler, more adaptable solution, accommodating users of different heights and requiring less effort to weld. It also simplifies operation by allowing for easy clamping and un-clamping of the plate, adjusting its height, and adapting to users of different heights. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and implementing regulations.

[0022] Reference Figure 1 - Figure 4A welding plate positioner includes a base plate 1. A first motor 2 is fixedly connected to the top of the base plate 1. A first bevel gear 3 is fixedly connected to the output end of the first motor 2. A second bevel gear 4 is meshed with the first bevel gear 3. A first drive screw 5 is fixedly connected to the top of the second bevel gear 4. A first screw nut 6 is fitted on the first drive screw 5 and is adapted to the first drive screw 5. A circular tube 7 is fixedly connected to the outer wall of the first screw nut 6. A first frustum 8 is fixedly connected to the top of the circular tube 7. The first frustum 8 has four arc-shaped grooves 9, and each of the four arc-shaped grooves 9 contains a... A sliding rod 10 is provided, which is slidably connected to a first truncated cone 8. A slider 11 is fixedly connected to the top of each of the four sliding rods 10. A second truncated cone 12 is provided on the top of the first truncated cone 8. Four sliding grooves 13 are provided on the second truncated cone 12, and the sliders 11 are disposed within the sliding grooves 13, slidably connected to the second truncated cone 12. A clamping plate 14 is fixedly connected to the top of each of the four sliders 11. Support plates 101 are fixedly connected to the tops of both ends of the base plate 1. A sleeve plate 15 is fixedly connected to the outer wall of the support plate 101, and a limit rod 16 is slidably connected to the inner wall of the sleeve plate 15. The limit rod 16 is fixedly connected to the second truncated cone. The outer wall of the 12-shaped plate utilizes a technique that allows the clamping plate to move closer to the plate during the lifting process and to move further away from the plate during the lowering process. Therefore, after the plate is clamped and fixed, continuing to rotate the output of the first motor allows the plate to continue rising until it reaches a suitable height for the user's operation. This allows the user to weld in a natural posture, reducing fatigue and discomfort, making operation easier and ensuring work efficiency. After the second platform descends to its initial position, continuing to rotate the output of the first motor reverses the second platform, allowing the clamping plate to move away from the plate and remove the welded plate. This effectively solves the problems mentioned in the background technology, such as the inability of most existing devices to adjust the plate height, their inability to adapt to different user heights, poor adaptability, the need for operators to weld in unnatural postures, increased fatigue and discomfort, inconvenience, and the need for more time in welding operations, leading to reduced work efficiency. This device achieves simple operation, easy clamping and unfixing of the plate, easy adjustment of the plate height, and adaptability to users of different heights, resulting in a highly adaptable technical effect.

[0023] In this embodiment, a limiting ring 17 is fixedly connected to the outer wall of the bottom end of the first drive screw 5. The first drive screw 5 and the limiting ring 17 are both fitted with the same fixing frame 18. The fixing frame 18 is fixedly connected to the base plate 1. When the first drive screw 5 rotates, it will cause the limiting ring 17 to rotate. The limiting ring 17 will rotate within the fixing frame 18, thereby ensuring the stability of the first drive screw 5 when it rotates.

[0024] In this embodiment, four casters 19 are fixedly connected to the bottom of the base plate 1.

[0025] In this embodiment, a base 20 is provided at the bottom of the base plate 1, and the movable wheel 19 contacts the top of the base 20.

[0026] In this embodiment, side plates 21 are fixedly connected to the top of both ends of the base 20. A third bevel gear 22 is provided on one side of one of the side plates 21. The third bevel gear 22 is meshed with a fourth bevel gear 23. A support plate 24 is provided on the top of the fourth bevel gear 23. The support plate 24 is fixedly connected to the side plate 21. A second motor 25 is fixedly connected to the top of the support plate 24. The output end of the second motor 25 is fixedly connected to the fourth bevel gear 23.

[0027] In this embodiment, a second drive screw 26 is fixedly connected to one side of the third bevel gear 22. Both ends of the second drive screw 26 are fitted with bearing seats. The second drive screw 26 is fixedly connected to the inner wall of the inner ring of the bearing on the bearing seat. A second screw nut 27 is fitted onto the second drive screw 26. The second screw nut 27 passes through the base plate 1 and is fixedly connected to the base plate 1.

[0028] In this embodiment, guide rods 28 are provided at both ends of the base plate 1. The base plate 1 is slidably connected to the guide rods 28, and the guide rods 28 are fixedly connected to the side plate 21. When the base plate 1 moves, it will move along the guide rods 28, thereby ensuring the stability of the base plate 1 when it moves.

[0029] Working principle: When using this device, place the plate to be welded on the second frustum 12, start the first motor 2, the output of the first motor 2 will drive the first bevel gear 3 to rotate, the first bevel gear 3 will drive the second bevel gear 4 to rotate, the second bevel gear 4 will drive the first drive screw 5 to rotate, the first drive screw 5 will drive the first screw nut 6 to rotate, the first screw nut 6 will drive the round tube 7 to rotate, the round tube 7 will drive the first frustum 8 to rotate, the first frustum 8 will press the slide rod 10 to move within the arc groove 9, the arc groove 9 will also carry the slider 11 to move within the slide groove 13, then the four slide rods 10 will move towards... As the center of the first frustum 8 moves, the four sliders 11 also move towards the center of the second frustum 12. The sliders 11 then move the clamping plate 14, which moves towards the plate until it contacts it, clamping and fixing the plate. After contact with the plate, the clamping plate 14 can no longer move, and the first frustum 8 can no longer rotate. If the first drive screw 5 continues to rotate, it will cause the first screw nut 6 to rise. The rising of the first screw nut 6 will cause the circular tube 7 to rise, which in turn will cause the first frustum 8 to rise, and the first frustum 8 will cause the second frustum 12 to rise. 2. The limit rod 16 will rise along the sleeve plate 15. Adjust the height of the second truncated cone 12 to a suitable operating position, and then welding can begin. When it is necessary to move the plate, the second motor 25 can be started. The output end of the second motor 25 will drive the fourth bevel gear 23 to rotate, which in turn drives the third bevel gear 22 to rotate. The third bevel gear 22 will drive the second drive screw 26 to rotate, which will then move the second screw nut 27. The second screw nut 27 will move the base plate 1, which will move along the guide rod 28. The movement of the base plate 1 will move the support plate 101, supporting... Plate 101 will move along with sleeve 15, sleeve 15 will move along with limit rod 16, limit rod 16 will move along with second truncated cone 12, thus moving the plate and adjusting its position. After welding is completed, the output end of the first motor 2 will reverse, thus reversing the first truncated cone 8, which will return the four sliding rods 10 to their initial positions, allowing clamp 14 to move away from the plate and remove it. When the sliding rods 10 return to their initial positions, the first drive screw 5 will continue to reverse, causing the first screw nut 6 to descend. The first screw nut 6 will then lower the round tube 7, which in turn will lower the first truncated cone 8 back to its initial position.
