TECHNICAL FIELD

[0001] The application belongs to the technical field of production of truck-mounted container handlers, and particularly relates to an automatic stamping system and method for production of truck-mounted container handlers. BACKGROUND

[0002] The fixed outer gantry and the movable inner gantry in the truck-mounted container handler gantry system jointly constitute the core frame of the lifting function of the device. The fixed outer gantry, as the main support structure, is rigidly connected to the vehicle body at the bottom and plays a key role in load transmission and overall stability. Its vertical guide rail provides precise guidance for the movement of the inner gantry. The movable inner gantry is nested inside the outer gantry and is driven by a hydraulic cylinder to realize vertical lifting, directly bearing the weight of the forks and the goods. The lifting height of the inner gantry determines the working range of the truck-mounted container handler. The coordinated operation of the two sets of gantries realizes the functional division of "fixed support of the outer gantry and dynamic lifting of the inner gantry": the outer gantry acts as a static skeleton to ensure the stability of the device, while the inner gantry acts as a flexible arm to complete the precise positioning of the goods. This layered design not only ensures the structural strength of the gantry system under high load, but also realizes efficient use of space through the relative movement of the inner and outer gantries, allowing the truck-mounted container handler to achieve greater lifting height under limited body height. The coordination accuracy of the two directly affects the stability and positioning accuracy of the lifting of the goods, and is a key design for balancing the stability and flexibility of the device.

Detailed Implementation

[0023] 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.

[0024] like Figures 1-2 As shown, this embodiment provides an automated stamping system for the production of forklift gantry. The automated stamping system includes a load-bearing component 1, a crossbeam plate loading component 2, a stamping assembly component 3, a riveting robot 4, and a welding robot 5.

[0025] like Figures 3-4 As shown, the forklift gantry includes an outer gantry 7 and an inner gantry 8 disposed therein. The outer gantry 7 includes vertical beam plate components 71, horizontal beam plate components 72, press-fit connectors 73, lever-type anti-fall components 74, and pins 75. The inner gantry 8 is slidably restricted between two parallel vertical beam plate components 71. Horizontal beam plate components 72 are installed at both ends of each vertical beam plate component 71 through press-fit connectors 73. Two rows of staggered lever-type anti-fall components 74 are installed in each vertical beam plate component 71, and pins 75 are installed at the fulcrum of the lever-type anti-fall components 74.

[0026] like Figure 5 As shown, the vertical beam plate component 71 includes an H-beam body 711. After pre-drilling, the H-beam body 711 has press-fit connection holes 712 at both ends of the web, two rows of slide rails 713 in the middle of the web, and several pin riveting holes 714 on both side plates.

[0027] like Figure 6As shown, the crossbeam plate component 72 includes a crossbeam plate body 721. Two sets of snap-fit ​​components are symmetrically installed on the inner side of the crossbeam plate body 721. Each set of snap-fit ​​components consists of an outer U-shaped snap-fit ​​protrusion 722 and an inner U-shaped snap-fit ​​protrusion 723. The outer U-shaped snap-fit ​​protrusion 722 / inner U-shaped snap-fit ​​protrusion 723 and the inner cavity shape of the H-beam body 711 located on the outer / inner periphery of the web plate are mutually matched. The outer U-shaped snap-fit ​​protrusion 722 and the inner U-shaped snap-fit ​​protrusion 723 are each provided with a press-fit connection hole 724 that matches the position of the press-fit connection hole 712. The press-fit connection component 73 is obtained by press-fitting rivets that extend into the press-fit connection hole 724 and the press-fit connection hole 712 through the riveting robot 4. The crossbeam plate component 72 located on the upper layer has a rope through hole in the middle of its crossbeam plate body 721.

[0028] like Figure 7 As shown, the lever-type fall arrestor 74 includes a grooved lever 741. The middle part of the grooved lever 741 is provided with a fulcrum seat 742 for easy insertion of the pin 75. The two side plates of the grooved lever 741 are connected to fall arrest blocks 744 via connecting plates 743. The two ends of the connecting plates 743 are rotatably connected to the outer ends of the side plates of the grooved lever 741 and the rear end lugs of the fall arrest blocks 744, respectively. The outer end of the fall arrest blocks 744 is provided with an arc-shaped stop. The fall arrest blocks 744 slide and are restricted in the corresponding slide rails 713. The pin 75 is driven to move by the riveting robot 4 and is riveted into the pin riveting hole 714 through the rotating hole of the fulcrum seat 742.

[0029] like Figures 8-9 As shown, the inner mast 8 includes a carrier plate seat 801. The carrier plate seat 801 has grooved sliding plates 802 on both sides that slide and restrict the H-beam body 711 in the inner area of ​​the web. A hanger 803 is installed on the upper side of the carrier plate seat 801. The carrier plate seat 801 has a drive mounting groove 806 for easy installation of a rotary drive 804. The movable end of the rotary drive 804 is equipped with an annular rotating plate 805 for adding forks. The carrier plate seat 801 has an anti-detachment groove 807 on the front side of the drive mounting groove 806 to restrict the movement of the annular rotating plate 805.

[0030] The length of the grooved slide plate 802 is less than the length of the grooved lever 741. When the upper / lower side plate of the grooved slide plate 802 presses against the upper / lower anti-fall block 744 of the lever-type anti-fall component 74 and causes it to move inward, the lower / upper anti-fall block 744 of the lever-type anti-fall component 74 moves outward under the action of the lever.

[0031] When the inner gantry 8 is raised or lowered normally, the lever-type anti-fall component 74 can swing the lever to avoid the fall stop 744, without affecting the raising or lowering. When the inner gantry 8 falls accidentally, the fall stop 744 of the lever-type anti-fall component 74 does not have time to swing to avoid the fall, thus providing a fall protection buffer for the inner gantry 8 and preventing damage to the loaded explosive, fragile or high-value items or causing a safety accident.

[0032] like Figure 10 As shown, the supporting component 1 is used to support and clamp the horizontally placed vertical beam plate component 71. The supporting component 1 includes a base 101, on which two vertical beam plate positioning grooves 102 for placing the vertical beam plate component 71 are symmetrically opened inward on the upper side. The depth of the vertical beam plate positioning grooves 102 is matched with the thickness of the side plate in the H-beam body 711. Several tilting motors 103 are installed on the base 101 between the two vertical beam plate positioning grooves 102. The output end of the tilting motors 103 is equipped with a limiting rotating plate 104 for restricting the vertical beam plate component 71 from the top.

[0033] like Figure 11 As shown, there are two crossbeam plate loading assemblies 2, which are symmetrically arranged on the front and rear sides of the bearing assembly 1. The crossbeam plate loading assembly 2 is used to clamp the crossbeam plate component 72 at both ends of the vertical beam plate component 71 and to cooperate with the riveting robot 4 to install the press-fit connector 73. It also cooperates with the welding robot 5 to perform welding reinforcement operations between the vertical beam plate component 71 and the crossbeam plate component 72. The crossbeam plate loading assembly 2 includes a base plate 201, a drive push rod 202, a grooved material carrier plate 203 and a suction cup 204. The base plate 201 is supported by the drive push rod 202 and the grooved material carrier plate 203 is supported by the drive push rod 202. The spacing between the two side plates of the grooved material carrier plate 203 is matched with the length of the crossbeam plate body 721. The suction cup 204 is embedded and fixed in the web of the grooved material carrier plate 203 near the two side plates.

[0034] like Figure 12 As shown, there are two stamping assembly components 3, symmetrically arranged on the left and right sides of the bearing component 1. The stamping assembly components 3 are used to pre-drill holes in the vertical beam plate component 71, fill the lever-type anti-fall component 74, and cooperate with the riveting robot 4 to install the pin component 75. The stamping assembly component 3 includes a common slide rail 31, on which are installed a slide rail stamping mechanism 32 for forming the slide rail 713, a hole-opening mechanism 33 for forming the press-fit connection hole 712 and the pin riveting hole 714, and an assembly mechanism 34 for filling the lever-type anti-fall component 74 into the corresponding installation position.

[0035] like Figure 13As shown, the slide block stamping mechanism 32 includes a first slider 321 that forms a first linear guide pair with the shared slide rail 31. A first horizontal push rod 323 is installed on the upper side of the first slider 321 via a first lifting push rod 322. A slide block forming punching cutter 324 is installed on the movable end of the first horizontal push rod 323. like Figure 14 As shown, the hole-opening mechanism 33 includes a second slider 331 that forms a second linear guide pair with the shared slide rail 31. A second horizontal push rod 333 is supported on the upper side of the second slider 331 by a support plate 332. A clamping frame 334 is installed at the movable end of the second horizontal push rod 333. A steering motor 335 is installed inside the clamping frame 334. A rotating block 336, whose movement is limited by the clamping frame 334, is installed at the output end of the steering motor 335. A hole-opening laser head 337 is embedded in the side end of the rotating block 336. The steering motor 335 drives the rotating block 336 and the hole-opening laser head 337 to rotate, thereby meeting the requirements for opening functional holes in different directions.

[0036] like Figure 15 As shown, the assembly mechanism 34 includes a third slider 341 that forms a third linear guide pair with the shared slide rail. A third horizontal push rod 343 is mounted on the upper side of the third slider 341 via a second lifting push rod 342. A groove-like frame 344 is mounted on the movable end of the third horizontal push rod 343. Positioning protrusions 345 are symmetrically mounted on both sides of the web of the groove-like frame 344. The distance between the two positioning protrusions 345 is matched with the length of the web of the groove-like lever 741. Mechanical grippers 346 for clamping the connecting plate 743 are symmetrically mounted on the two side plates of the groove-like frame 344. The inner side of the gripper of the mechanical gripper 346 is provided with a clamping positioning groove that matches the width of the connecting plate 743.

[0037] The automated stamping system also includes a controller 6, which is connected to the load-bearing component 1, the crossbeam plate loading component 2, the stamping assembly component 3, the riveting robot 4, and the welding robot 5.

[0038] This embodiment also provides an automated stamping method for a forklift gantry assembly, comprising the following steps: S1, Beam plate snap-fit ​​and press-fit connection The suction cup 204 of the crossbeam plate loading assembly 2 adsorbs the crossbeam plate body 721, and the drive push rod 202 pushes the channel-shaped material carrier plate 203 to align the snap-fit ​​of the crossbeam plate component 72 with the inner cavity of the H-beam of the vertical beam plate component; the riveting robot 4 inserts the press-fit rivet into the press-fit connection mating hole 724 and the press-fit connection hole 712, and press-fits to form the press-fit connection component 73; the welding robot 5 welds and reinforces the connection between the vertical beam plate component 71 and the crossbeam plate component 72.

Vertical beam positioning and pre-drilling treatment The vertical beam plate component 71 is placed horizontally in the vertical beam plate positioning groove 102 of the bearing component 1, and the limiting rotating plate 104 is pressed and fixed by the flipping motor 103. In order to make the limiting rotating plate 104 rotate smoothly to the top of the vertical beam plate component 71, the controller 6 starts the hole-opening mechanism 33 in the stamping assembly component 3. The hole-opening laser head 337 of the hole-opening mechanism 33 processes the riveting connection holes 712 at both ends of the web plate of the vertical beam plate component 71 and the pin riveting holes 714 on both side plates. The slide stamping mechanism 32 processes two rows of slides 713 in the middle of the web plate of the vertical beam plate component 71. S3, Lever-type fall arrestor component filling and pin installation The assembly mechanism 34 moves along the common slide rail 31 to above the vertical beam plate component 71. The mechanical gripper 346 clamps the connecting plate 743 of the lever-type fall arrestor component 74 and aligns the web position of the slot-type lever 741 with the positioning protrusion 345. The fall arrestor block 744 is embedded into the slide rail 713, and the riveting robot 4 presses the pin 75 into the rotating hole and pin riveting hole 714 of the fulcrum seat 742 to complete the installation of the lever-type fall arrestor component 74.

[0039] A specific application of this embodiment is as follows: Preparation Ensure that all components of the automated stamping system (load-bearing component 1, crossbeam plate loading component 2, stamping assembly component 3, riveting robot 4, welding robot 5, and controller 6) are in normal working condition, and prepare the raw materials required for production, such as vertical beam plate component 71, crossbeam plate component 72, lever-type anti-fall component 74, pin shaft component 75, and press rivets.

[0040] The controller 6 initiates the operation of the crossbeam plate loading assembly 2. The suction cup 204 of the crossbeam plate loading assembly 2 adsorbs the crossbeam plate body 721, driving the push rod 202 to push the channel-shaped loading plate 203, aligning the outer U-shaped snap-fit ​​protrusion 722 and inner U-shaped snap-fit ​​protrusion 723 of the crossbeam plate component 72 with the H-shaped steel inner cavity of the vertical beam plate component 71, thus achieving snap-fit ​​positioning of the crossbeam plate component 72 at both ends of the vertical beam plate component 71. Under the control of the controller 6, the riveting robot 4 inserts the press-fit rivets into the press-fit connection mating hole 724 of the crossbeam plate component 72 and the press-fit connection hole 712 of the vertical beam plate component 71, performing press-fit processing to form the press-fit connection part 73, completing the initial connection between the crossbeam plate component 72 and the vertical beam plate component 71. Following the instructions of the controller 6, the welding robot 5 welds and reinforces the connection between the vertical beam plate component 71 and the crossbeam plate component 72, enhancing the connection strength and ensuring the stability of the outer gantry structure.

[0041] The operator places the vertical beam plate component 71 horizontally within the vertical beam plate positioning groove 102 of the bearing assembly 1, ensuring accurate placement. The controller 6 activates the tilting motor 103, which drives the limiting rotating plate 104 to rotate above the vertical beam plate component 71 and press it firmly to prevent movement during subsequent processing. The controller 6 then controls the hole-opening mechanism 33 in the stamping assembly 3 to begin operation. The second slider 331 of the hole-opening mechanism 33 moves along the common slide rail 31 to a suitable position, and the second horizontal push rod 333 pushes the clamping frame 334, aligning the hole-opening laser head 337 with the two ends of the web plate and the two side plates of the vertical beam plate component 71. Under the control of the controller 6, the steering motor 335 drives the rotating block 336 and the hole-opening laser head 337 to rotate, machining the riveting connection holes 712 at the two ends of the web plate of the vertical beam plate component 71 and the pin riveting holes 714 on the two side plates. The slide stamping mechanism 32 begins operation under the control of the controller 6. The first slider 321 moves along the common slide rail 31 to the middle of the web of the vertical beam plate component 71. The first lifting push rod 322 and the first horizontal push rod 323 adjust the position of the slide forming punch 324 and process two rows of slide rails 713 in the middle of the web of the vertical beam plate component 71 to provide space for the subsequent installation of the lever-type anti-fall component 74.

[0042] The controller 6 controls the third slider 341 of the assembly mechanism 34 to move along the common slide rail 31 to a suitable position above the vertical beam plate component 71. Under the control of the controller 6, the second lifting push rod 342 and the third horizontal push rod 343 adjust the position of the groove-shaped frame 344 so that the positioning protrusion 345 of the groove-shaped frame 344 aligns with the web position of the groove-shaped lever 741. The mechanical gripper 346 clamps the connecting plate 743 of the lever-type fall arrestor 74 to ensure the accurate placement of the lever-type fall arrestor 74. The fall arrestor block 744 is embedded into the slide rail 713. Under the control of the controller 6, the riveting robot 4 presses the pin 75 into the rotating hole and pin riveting hole 714 of the fulcrum seat 742 to complete the installation of the lever-type fall arrestor 74, so that the outer gantry has a fall arrest buffer function.

[0043] Slotted slide plates 802 are installed on both sides of the carrier plate seat 801 to ensure that the slotted slide plates 802 can slide and be restricted within the area of ​​the H-beam body 711 located in the web. A hanger 803 is installed on the upper side of the carrier plate seat 801. A drive mounting slot 806 is opened in the carrier plate seat 801 to install a rotary drive 804. An annular rotating plate 805 for adding forks is installed on the movable end of the rotary drive 804. An anti-detachment groove 807 for restricting the movement of the annular rotating plate 805 is opened on the front side of the carrier plate seat 801 located in front of the drive mounting slot 806, thus completing the assembly of the inner mast 8.

[0044] The prefabricated inner mast 8 is pre-installed between the two vertical beam plate components 71 of the outer mast, ensuring that the grooved slide plate 802 slides smoothly within the slide rail 713. After installation, the mast system is debugged, and the avoidance function of the lever-type fall arrestor 74 during normal lifting and lowering of the inner mast 8 is checked. A certain number of samples are also taken to test the fall arrest buffer effect of the lever-type fall arrestor 74 in the event of an accidental fall of the inner mast 8, ensuring that the mast system meets the design requirements. Through the above steps, a forklift mast with an outer mast having fall arrest buffer function and an inner mast having rotation function is produced using this automated stamping system and method.
