Description

Technical Field

[0001] The present invention relates to the technical field of container guide rail welding, in particular to a positioning tool for container guide rail welding processing. Background Art

[0002] In modern container manufacturing, guide rails are key load-bearing components, and the quality of their welding directly impacts the structural strength and service life of the container. During the guide rail welding process, precise positioning is essential for ensuring weld quality, and the performance of the positioning tooling plays a decisive role. Existing container rail welding and positioning fixtures often suffer from insufficient positioning accuracy. Traditional fixtures often utilize fixed-pitch positioning slots, making them difficult to adapt to the welding requirements of rails of varying sizes. This necessitates frequent fixture replacements when producing rails of varying sizes, resulting in low production efficiency and increased costs. Furthermore, some fixtures feature simplistic clamping mechanisms that fail to provide stable positioning of the rails. This allows for slight displacement of the rails during welding, resulting in weld deviations and poor weld quality. In terms of compatibility, existing tooling has limited versatility. With the development of the container shipping industry, requirements for rail shapes and sizes are becoming increasingly diverse, with rails featuring specialized flanges or grooves becoming increasingly common. Most traditional tooling is unable to accommodate these specialized rails, forcing companies to invest heavily in specialized tooling equipment, further increasing production costs. Furthermore, existing positioning tooling exhibits significant flaws in the unloading process. After welding, the close contact or adsorption between the guide rail and the positioning slot makes unloading difficult. Manual unloading is not only inefficient but also prone to scratching or deformation of the guide rail surface. Automated unloading, lacking auxiliary devices, makes it difficult to precisely grasp the guide rail, impacting the continuity of the production process.

[0003] In response to the above-mentioned problems in the existing technology, there is an urgent need for a positioning tool that can accurately adjust the positioning spacing, is compatible with various guide rail specifications, and has an efficient blanking function. Summary of the Invention

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1 The present invention provides a technical solution: a positioning tool for container guide rail welding processing, comprising a base plate 1, both sides of the top of the base plate 1 are movably connected to a support seat 2 through an adjustment mechanism, the top of the support seat 2 is fixedly connected to a positioning frame 3, both sides of the positioning frame 3 are provided with a positioning groove 4, a gap plate 7 is installed inside the positioning groove 4 through a plug-in assembly, guide rails 5 are installed on both sides of the gap plate 7 inside the positioning groove 4, a connecting toggle plate 6 is welded to the top of the two guide rails 5, and auxiliary pressing mechanisms are provided on both sides of the positioning frame 3, and the adjustment mechanism includes a motor 10 installed at the top center of the base plate 1 and a motor 10 opened at the top of the base plate 1. The chute 11 on the side, the opposite side of the two chute 11 is provided with a card slot 12 that passes through the inner cavity of the base plate 1, and the two sides of the chute 11 are slidably connected with a slider 17, the top of the slider 17 is fixedly connected to the bottom of the support base 2, the output end of the motor 10 is fixedly connected to the rotating shaft 13, the other end of the rotating shaft 13 extends to the inner cavity of the base plate 1 and is fixedly connected to the driving gear 14, and both sides of the driving gear 14 are meshed with sliding tooth plates 15, and the opposite sides of the two sliding tooth plates 15 are fixedly connected with a card plate 16, and the other end of the card plate 16 extends to the interior of the chute 11 through the card slot 12 and is fixedly connected to the slider 17.

[0020] Among them, this embodiment uses the base plate 1 as the basic bearing component, and its top two sides are movably connected to the support seat 2 through an adjustment mechanism. The adjustment mechanism is driven by a motor 10, and the motor 10 is installed at the top center position of the base plate 1. When working, the motor 10 drives the rotating shaft 13 to rotate, and the driving gear 14 connected to the rotating shaft 13 rotates accordingly. The sliding tooth plate 15 engaged with the driving gear 14 moves in the inner cavity of the base plate 1, and the sliding tooth plate 15 is connected to the slider 17 through the clamping plate 16, so as to realize the sliding of the support seat 2 on the slide groove 11. The distance between the two support seats 2 can be accurately adjusted according to the size requirements of container guide rails of different specifications to ensure that the positioning tooling is suitable for the welding processing requirements of various guide rails. Furthermore, positioning slots 4 are provided on both sides of the positioning frame 3 fixed on the top of the support seat 2, and gap plates 7 are installed in the positioning slots 4 through plug-in components.

[0021] Among them, the plug-in assembly is composed of an insert plate at the bottom of the gap plate 7 and a slot at the bottom of the inner cavity of the positioning groove 4. By replacing the gap plates 7 of different thicknesses, the spacing between the guide rails 5 in the positioning groove 4 can be flexibly adjusted to meet the requirements of different welding processes for the guide rail spacing. The guide rails 5 are placed on both sides of the gap plate 7 in the positioning groove 4, and the top is welded to the elbow plate 6. Furthermore, the auxiliary clamping mechanism includes a mounting frame 32 installed on one side of the support seat 2, the inner side of the mounting frame 32 is fixedly connected to the fixed plate 18, the outer side of the mounting frame 32 is fixedly connected to the electric push rod 19, the output end of the electric push rod 19 extends to the inner side of the mounting frame 32 and is fixedly connected to the trapezoidal plate 20, the inner sliding connection of the fixed plate 18 is connected to the pressure rod 21, the top of the pressure rod 21 is fixedly connected to the trapezoidal block 23, the bottom of the pressure rod 21 extends to the bottom of the fixed plate 18 and is fixedly connected to the pressure plate 22, and the outer surface of the pressure rod 21 between the fixed plate 18 and the trapezoidal block 23 is provided with a spring 24.

[0022] The mounting bracket 32 ​​is fixed to one side of the support seat 2. When the guide rail 5 needs to be clamped, the electric push rod 19 is started to push the trapezoidal plate 20 to move inward. The trapezoidal groove 25 on the trapezoidal plate 20 cooperates with the trapezoidal block 23 on the top of the pressure rod 21 to move the pressure rod 21 downward, and the pressure plate 22 at the bottom presses the guide rail 5. The anti-slip pad at the bottom of the pressure plate 22 increases the friction with the guide rail surface to prevent the guide rail from shifting during the welding process. The spring 24 is sleeved outside the pressure rod 21 and is located between the fixed plate 18 and the trapezoidal block 23 to play a role in buffering and auxiliary reset. The limit groove 26 on the top wall of the mounting bracket 32 ​​cooperates with the limit plate 27 to limit the movement of the trapezoidal plate 20 to ensure the stability and accuracy of the clamping operation.

[0023] Furthermore, the iron groove 8 on one side of the inner wall of the positioning groove 4 is engaged with the iron block 9.

[0024] Among them, when positioning, the operator can select an iron block 9 of appropriate thickness according to the different specifications of the guide rail 5, so that the guide rail 5 can be squeezed to fit tightly with the gap plate 7, thereby making the horizontal positioning effect of the guide rail 5 better, and thus effectively avoiding the deviation of the guide rail during welding.

[0025] Working principle: In actual operation, the operator can input the corresponding data into the control system of the tooling according to the size parameters of the guide rail 5 to be welded. The built-in displacement sensor of the tooling monitors the moving position of the support seat 2 in real time to ensure that the adjustment mechanism accurately adjusts the support seat 2 to the appropriate position. When the guide rail 5 is placed in the positioning groove 4, the pressure sensor starts to work and detects the clamping force of the pressure plate 22 on the guide rail 5 in real time. If the pressure does not reach the preset value, the system automatically controls the electric push rod 19 to further push the trapezoidal plate 20 until the clamping force meets the requirements. In order to improve the compatibility of tooling, a modular gap plate 7 is designed. For container guide rails of different specifications, the operator only needs to replace the gap plate 7 of the corresponding thickness to control the gap size between the guide rails 5. There is no need to re-purchase a whole set of tooling equipment, which greatly reduces the equipment cost. At the same time, by adding iron grooves 8 and iron blocks 9 inside the positioning grooves 4, the guide rails 5 can be better positioned. During positioning, the operator can select iron blocks 9 of appropriate thickness according to the different specifications of the guide rails 5, so that the guide rails 5 can be squeezed to fit tightly with the gap plate 7, thereby making the horizontal positioning effect of the guide rails 5 better.

[0026] In the field of automated production, this positioning tooling can be deeply integrated with automated welding equipment such as welding robots and automatic wire feeders. When the guide rail 5 completes positioning and clamping, the tooling sends a signal to the automated welding equipment through the communication interface, and the welding equipment automatically starts and performs welding work to connect the elbow plate 6 and the guide rail 5 according to the preset welding path and process parameters. During the welding process, the tooling continuously monitors the position status of the guide rail. If a slight offset occurs, the auxiliary clamping mechanism can be fine-tuned to ensure the stability of the welding quality.

[0027] Example 2 The present invention provides a technical solution: a positioning tool for container guide rail welding processing, comprising a base plate 1, both sides of the top of the base plate 1 are movably connected to a support seat 2 through an adjustment mechanism, the top of the support seat 2 is fixedly connected to a positioning frame 3, positioning grooves 4 are provided on both sides of the positioning frame 3, a gap plate 7 is installed inside the positioning groove 4 through a plug-in assembly, the plug-in assembly includes a plug-in plate installed at the bottom of the gap plate 7 and a slot opened at the bottom of the inner cavity of the positioning groove 4, guide rails 5 are installed on both sides of the gap plate 7 inside the positioning groove 4, connecting elbow plates 6 are welded to the tops of the two guide rails 5, auxiliary clamping mechanisms are provided on both sides of the positioning frame 3, an iron groove 8 is provided on one side of the inner wall of the positioning groove 4, and an iron block 9 is clamped inside the iron groove 8.

[0028] Furthermore, the adjustment mechanism includes a motor 10 installed at the top center of the base plate 1 and a slide groove 11 opened on both sides of the top of the base plate 1. The opposite side of the two slide grooves 11 is provided with a card slot 12 that passes through the inner cavity of the base plate 1, and both sides of the slide groove 11 are slidably connected with a slider 17. The top of the slider 17 is fixedly connected to the bottom of the support base 2. The output end of the motor 10 is fixedly connected to the rotating shaft 13, and the other end of the rotating shaft 13 extends to the inner cavity of the base plate 1 and is fixedly connected to the driving gear 14. Both sides of the driving gear 14 are meshed with sliding tooth plates 15, and the opposite sides of the two sliding tooth plates 15 are fixedly connected with a card plate 16. The other end of the card plate 16 extends to the interior of the slide groove 11 through the card slot 12 and is fixedly connected to the slider 17.

[0029] Furthermore, the auxiliary pressing mechanism includes a mounting bracket 32 ​​installed on one side of the support seat 2, the inner side of the mounting bracket 32 ​​is fixedly connected to the fixing plate 18, the outer side of the mounting bracket 32 ​​is fixedly connected to the electric push rod 19, the output end of the electric push rod 19 extends to the inner side of the mounting bracket 32 ​​and is fixedly connected to the trapezoidal plate 20, the inner side of the fixing plate 18 is slidably connected to the pressure rod 21, the top of the pressure rod 21 is fixedly connected to the trapezoidal block 23, the bottom of the pressure rod 21 extends to the bottom of the fixing plate 18 and is fixedly connected to the pressure plate 22, the bottom of the pressure plate 22 is fixedly connected to the anti-slip pad, the outer surface of the pressure rod 21 between the fixing plate 18 and the trapezoidal block 23 is provided with a spring 24, the bottom of the trapezoidal plate 20 is provided with a trapezoidal groove 25 adapted to the trapezoidal block 23, the top wall of the mounting bracket 32 ​​is provided with a limiting groove 26, the bottom of the limiting groove 26 is fixedly connected to the limiting plate 27, and the bottom of the limiting plate 27 is fixedly connected to the trapezoidal plate 20.

[0030] Furthermore, multiple sets of lifting mechanisms are provided on both sides of the top of the base plate 1, and the lifting mechanism includes a support base 28 installed on the top of the base plate 1, and a movable plate 29 is hinged on the top of the support base 28. A pneumatic push rod 30 is fixedly connected to the bottom of one side of the movable plate 29, and a push rod 31 is fixedly connected to the top of the other side of the movable plate 29, and the bottom of the pneumatic push rod 30 is fixedly connected to the base plate 1, and the support base 28 is located at one quarter of the bottom of the movable plate 29 close to the side of the pneumatic push rod 30.

[0031] This embodiment, based on the first embodiment, adds multiple lifting mechanisms on both sides of the top of the base plate 1. The lifting mechanism uses the support base 28 as the support point, and the movable plate 29 is hinged to the top of the support base 28. The support base 28 is located at a quarter of the bottom of the movable plate 29 on the side close to the pneumatic push rod 30. The principle of the movable plate is used to achieve force amplification.

[0032] Among them, the bottom of the pneumatic push rod 30 is fixed on the base plate 1. After welding is completed, the pneumatic push rod 30 is started, and the pneumatic push rod 30 pushes one side of the movable plate 29 upward, and the push rod 31 on the other side is lifted upward, and the welded guide rail 5 placed in the open positioning groove 4 is pushed out of the positioning groove 4 to a certain height. Since the top of the positioning groove 4 is open and the top of the guide rail does not contact the positioning groove, the push rod 31 can easily lift the guide rail assembly, so that the guide rail 5 is freed from the constraint of the positioning groove 4, greatly reducing the friction and adsorption force between the guide rail 5 and the positioning groove 4. At this time, the operator or automated handling equipment can more easily grab or carry the guide rail 5 without consuming a lot of effort to overcome the restrictions of the positioning groove 4 on the guide rail 5, which significantly improves the blanking efficiency, reduces the problems of scratches and deformation of the guide rail that may occur during the blanking process, and ensures the quality of the guide rail finished product. The other structures are consistent with the first embodiment. The adjustment mechanism can adjust the position of the support seat 2 according to the size of the guide rail, and the auxiliary clamping mechanism clamps and fixes the guide rail 5 after it is placed. The coordinated work of the lifting mechanism and the auxiliary clamping mechanism provides a more stable positioning foundation for the guide rail welding and also facilitates the subsequent cutting process. The other structures are consistent with those of Example 1. The adjustment mechanism can adjust the position of the support seat 2 according to the size of the guide rail. The auxiliary clamping mechanism clamps and fixes the guide rail 5 after it is lifted up. Through the coordinated work of the lifting mechanism and the auxiliary clamping mechanism, a more stable positioning foundation is provided for the guide rail welding, and convenience is also provided for the subsequent cutting process.

[0033] Working principle: During the guide rail welding preparation stage, the operator first uses the adjustment mechanism to adjust the position of the support seat 2 according to the guide rail size, places the guide rail 5 into the positioning groove 4, and then starts the pneumatic push rod 30. At this time, the displacement sensor monitors the lifting height of the push rod 31 in real time, and the control system accurately controls the stroke of the pneumatic push rod 30 according to parameters such as the guide rail thickness, ensuring that the push rod 31 lifts the guide rail 5 to the appropriate height. To further enhance safety, multiple layers of infrared sensors are installed around the jacking mechanism. When a person or object enters a dangerous area, the infrared sensors immediately send a signal to the control system, which quickly suspends the operation of the pneumatic push rod 30 and triggers an audible and visual alarm to alert on-site personnel. Furthermore, the system records the time and location of any abnormality, facilitating subsequent safety hazard inspections and equipment maintenance. In terms of production process optimization, the lifting mechanism can be intelligently linked with automated handling equipment such as AGV carts and robotic arms. When welding is completed, the pneumatic push rod 30 causes the ejector rod 31 to eject the guide rail assembly from the positioning groove. The automated handling equipment recognizes through sensors that the guide rail assembly is in a position that is convenient for grasping, automatically moves to the tooling, and uses a vacuum suction cup or a mechanical gripper to transport the welded guide rail assembly to the next workstation. The entire process does not require human intervention, achieving seamless connection of the production process. In addition, by installing a visual recognition system on the automated handling equipment, the size and position of the guide rail assembly can be reconfirmed to ensure the accuracy of the handling process, further improve production efficiency, and reduce the errors and labor intensity caused by manual handling. At the same time, the working data of the lifting mechanism, such as the number of lifts and working hours, can be connected to the production management system. Through data analysis, the production plan and equipment maintenance cycle can be optimized to achieve intelligent production management.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
