Technical Field

[0001] This invention relates to the field of workpiece processing equipment technology, and more specifically, to a positioning and transport vehicle. Background Technology

[0002] When machining workpieces or molds using CNC machining, CNC boring machines, etc., it is necessary to transfer the workpieces from the feeding equipment to the machining equipment.

[0003] The weight of the workpieces is often as high as hundreds of kilograms or even tens of tons, so that the robotic arm cannot perform the loading and unloading process by grasping the workpiece. In the existing technology, the loading and unloading of the above-mentioned medium and large workpieces is often achieved by manual operation.

[0004] In addition, after production or transfer, the workpiece may be tilted at its placement angle, requiring it to be aligned.

[0005] However, manual handling poses safety hazards, has low handling efficiency and high labor costs. Furthermore, if the workpiece needs to be aligned after transfer, additional alignment equipment must be set up, which takes up a lot of space and makes handling more difficult.

[0017] Furthermore, the supporting mechanism includes a support component and a supporting frame.

[0018] The support component has a bearing portion formed on its top, and both the transfer mechanism and the alignment mechanism are located on the support component.

[0019] The load-bearing frame is disposed on the movable component, the support component is disposed on the load-bearing frame, and the height adjustment component is throttle-connected to the load-bearing frame.

[0020] Furthermore, the mounting bracket is provided with a guide structure.

[0022] Furthermore, the support assembly includes a support platform and forks embedded in the support platform.

[0023] The top surface of the support platform is the support part.

[0024] The forks are capable of moving along the platform toward both sides of the platform and extending outwards from the platform.

[0051] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0052] Please see Figures 1 to 4 The alignment transport vehicle provided in this embodiment includes a carrying mechanism 100, a transfer mechanism 200, an alignment mechanism 300, and a moving mechanism 400.

[0053] The supporting mechanism 100 has a supporting portion for placing workpieces. A transfer mechanism 200 is located on the supporting portion and includes a fixing member 210 for fixing the workpiece, which is movable relative to the supporting portion. An alignment mechanism 300 is located on one side of the supporting portion and has an alignment end that is movable relative to the supporting portion to outside the supporting portion, with the direction of movement of the alignment end parallel to the direction of movement of the fixing member 210. A moving mechanism 400 is located at the bottom of the supporting mechanism 100 and includes a horizontal moving component 410 and a height adjusting component 420. The horizontal moving component 410 drives the supporting mechanism 100 to move along a preset trajectory, and the height adjusting component 420 is located on the horizontal moving component 410 and is connected to the supporting mechanism 100 in a transmission manner.

[0054] Specifically, in this embodiment, the moving mechanism 400 can drive the carrying mechanism 100 and the moving mechanism 400 and the alignment mechanism 300 set on the carrying mechanism 100 to move together. After the alignment transport vehicle moves to the preset position, the height adjustment component 420 is driven to adjust the height of the carrying mechanism 100 and the alignment mechanism 300 so that the fixed part 210 in the transfer mechanism 200 is relative to the position of the workpiece, realizing the precise positioning and height adaptation of the whole vehicle, adapting to various processing equipment, and the fixed part 210 can move relative to the carrying part to contact the workpiece, thereby docking with the workpiece.

[0055] After the fixing member 210 docks with the workpiece, the workpiece moves to the bearing part along with the fixing member 210 under the drive of the transfer mechanism 200, or moves out of the bearing part under the drive of the fixing member 210. This realizes the picking action at the workpiece production position and the sending action at the workpiece processing position, eliminating the need for manual transfer, resulting in higher transfer efficiency and better safety. Furthermore, in this embodiment, the alignment mechanism 300 can drive the alignment end to move collinearly with the transfer mechanism 200, enabling the alignment end to push the workpiece in a statically placed state to realize the workpiece alignment action. After the transfer is completed, the workpiece is directly aligned in position without the need for an additional independent alignment device, saving space and improving positioning accuracy.

[0056] The alignment transport vehicle provided in this embodiment has a high degree of overall structural integration and flexible operation. While reducing labor costs and equipment complexity, it also improves the automation level and overall efficiency of the production system.

[0057] In this embodiment, the moving mechanism 400 further includes a mounting frame 430. The height adjustment assembly 420 includes a lifting member 440, which has a lifting end 441. There are two lifting members 440, and the lifting ends 441 of the two lifting members 440 are respectively disposed on both sides of the mounting frame 430 and respectively connected to both sides of the supporting mechanism 100.

[0058] In this embodiment, the height adjustment component 420 includes two lifting members 440 with lifting ends 441, and the lifting ends 441 of the two lifting members 440 are respectively disposed on both sides of the mounting frame 430 and correspondingly connected to both sides of the bearing mechanism 100.

[0059] In this structure, the symmetrically distributed dual lifting components 440 work together to enhance the stability and load balance of the load-bearing mechanism 100 during height adjustment, effectively avoiding uneven loading or jamming, making it particularly suitable for the precision positioning of heavy workpieces. Simultaneously, the dual-sided synchronous lifting mechanism further optimizes the structural rigidity and stability of the entire vehicle, enabling the alignment transport vehicle to achieve faster and more precise height adaptation when dealing with workpieces of different heights, thereby improving the reliability and safety of the alignment transport vehicle provided in this embodiment.

[0060] Specifically, in this embodiment, the lifting member 440 is a lifting screw, and the lifting end 441 is disposed on the screw and engages with the thread on the surface of the screw, so that the screw can drive the lifting end 441 to rise or fall by rotating.

[0061] In this embodiment, the mounting bracket 430 is equipped with a lifting motor, which drives a drive shaft via a gear chain. Two lifting lead screws are respectively connected to both ends of the drive shaft via gear transmission. This embodiment uses a single motor and a single shaft transmission to drive the gears synchronously, thereby ensuring the strict synchronous operation of the two lifting lead screws.

[0062] In this embodiment, the horizontal moving component 410 includes a moving track and a moving member. The moving track is used to guide the moving direction of the support mechanism 100. The moving member is disposed on the moving track and can move along the moving track. The mounting bracket 430, the height adjustment component 420, and the support mechanism 100 are all disposed on the moving member.

[0063] Specifically, in this embodiment, the moving track is used to achieve moving guidance. The moving component is set on the moving track and can move along the moving track to make the bearing mechanism 100, the transfer mechanism 200 and the alignment mechanism 300 reach the preset position. In this embodiment, the mounting bracket 430, the height adjustment component 420 and the bearing mechanism 100 are all set on the moving component.

[0064] In this structure, the moving track provides rigid guidance and constraint to the overall direction of movement, so as to ensure the directional stability and trajectory accuracy of the alignment transport vehicle during horizontal movement and avoid deviation or off-tracking during movement.

[0065] The moving component, acting as an integrated load-bearing platform, enables the mounting frame 430, height adjustment assembly 420, and load-bearing mechanism 100 to move synchronously and smoothly, reducing the cumulative errors and coordination problems that may arise from the separate driving of multiple components. The track-guided mechanism also enhances the torsional resistance and overall rigidity of the transport vehicle under heavy load or high-speed operating conditions, facilitating docking with external equipment (such as machining centers and silos) and improving the repeatability and reliability of the entire loading and unloading system.

[0066] In this embodiment, the supporting mechanism 100 includes a supporting component and a supporting frame. A supporting portion is formed on the top of the supporting component, and both the transfer mechanism 200 and the alignment mechanism 300 are located on the supporting component. The supporting frame is located on the movable part, the supporting component is located on the supporting frame, and the height adjustment component 420 is drively connected to the supporting frame.

[0067] Specifically, in this embodiment, the support component and the load-bearing frame form a double-layer load-bearing structure. The support component directly supports the workpiece and integrates the transfer mechanism 200 and the alignment mechanism 300, while the load-bearing frame is fixed to the moving parts by bolts or welding and achieves overall lifting by lifting screws.

[0068] In this structure, the weight of the workpiece and the force of the mechanism are distributed to the load-bearing frame through the support components, and then the rigid structure of the load-bearing frame is used to evenly transfer the force to the moving mechanism 400, thereby reducing the risk of deformation caused by off-center loading, which is especially suitable for frequent handling of heavy workpieces.

[0069] Furthermore, in this embodiment, the support component and the load-bearing frame are connected in a detachable manner (specifically, bolted connection in this embodiment), allowing the transfer mechanism 200 and the alignment mechanism 300 to be installed, debugged, or maintained independently without disassembling the entire load-bearing frame. For example, the alignment mechanism 300 on the support component frequently comes into contact with the workpiece and is prone to wear; the modular design allows for quick component replacement, reducing downtime and maintenance costs.

[0070] Furthermore, in this embodiment, the support frame serves as a rigid foundation platform, providing a stable support reference for the height adjustment component 420. The lifting screw is connected to the support frame to drive the entire support component and the workpiece to rise and fall synchronously, avoiding tilting or jamming caused by asynchronous lifting at multiple points. Simultaneously, the rigid connection between the support frame and the moving component ensures no swaying or offset during horizontal movement along the moving track, guaranteeing positioning accuracy during workpiece transfer and alignment.

[0071] In this embodiment, the mounting bracket 430 is provided with a guide structure 450. There are two guide structures 450, which are respectively provided on both sides of the mounting bracket 430. The two guide structures 450 are respectively connected to the two ends of the support frame on both sides of the support frame.

[0072] Specifically, in this embodiment, two guide structures 450 are provided on both sides of the mounting frame 430, and the two guide structures 450 are respectively connected to both ends of the bearing frame to form a "double-sided symmetrical guide" constraint structure, thereby providing guidance and stable support for the lifting and lowering movement of the bearing frame.

[0073] Among them, the two guide structures 450 can simultaneously limit the lateral displacement of the load-bearing frame during the height adjustment process, avoid the load-bearing frame tilting or jamming due to heavy workpiece load or uneven lifting driving force, and ensure that the load-bearing frame can always rise and fall smoothly along the preset vertical direction, thereby ensuring the positional stability of the upper support components, the transfer mechanism 200 and the workpiece, laying the foundation for the precise docking of the workpiece and the processing equipment.

[0074] Furthermore, the double-sided guide structure 450 can also distribute the vertical load transmitted by the load-bearing frame, reduce the unilateral force pressure on the height adjustment component 420 (such as the lifting screw), reduce the risk of wear or deformation of components due to local overload, and extend the overall service life of the equipment.

[0075] It should be noted that, in this embodiment, the guide structure 450 specifically includes two guide rails. The two guide structures 450 extend vertically and are spaced apart along the support frame to form a guide mechanism that is rectangularly distributed around the circumference of the support frame.

[0076] In this embodiment, the support assembly includes a support platform and forks 510 embedded in the support platform. The top surface of the support platform is a support portion. The forks 510 are tractively connected to a telescopic mechanism 500 within the support platform, enabling the forks to move along the support platform toward both sides and extend outwards from the support platform. The transfer mechanism 200 also includes a drive assembly, which is tractively connected to a fixing member 210 to drive the fixing member 210 to move along the support platform or the forks 510.

[0077] Specifically, in this embodiment, the bidirectional extendable forks 510 can be used to build conveyor platforms for transferring workpieces on both sides of the support platform. The drive component and the fixing component 210 in the transfer mechanism 200 cooperate to move along the conveyor platform and the support platform to realize the picking and sending action of the workpiece.

[0078] In this embodiment, the height adjustment assembly 420 further includes a balancing assembly. There are two balancing assemblies, which are respectively disposed on both sides of the mounting bracket 430 and connected to both ends of the mounting bracket 430.

[0079] Specifically, the balancing assembly in this embodiment includes nitrogen cylinders and nitrogen balancing cylinders. Two nitrogen cylinders and two nitrogen balancing cylinders are combined in a one-to-one correspondence and symmetrically arranged on both sides of the mounting frame 430 to counteract off-center loads during height adjustment.

[0080] When the load-bearing frame moves the support components and heavy workpieces up and down, if the workpiece's center of gravity shifts, the load on one side is too large, or the lifting screw experiences slight operational differences due to wear, the nitrogen balance cylinders on both sides can simultaneously output a reverse balancing force under the stable air pressure provided by the nitrogen cylinders. This flexibly buffers and offsets the impact of the off-center load, preventing the load-bearing frame from tilting to one side. Compared to a rigid balance structure, the nitrogen balance combination can compensate for load changes through adaptive air pressure adjustment, ensuring that the entire load-bearing mechanism 100 always moves smoothly up and down in the vertical direction. This not only ensures the positional stability of the upper transfer mechanism 200, the alignment mechanism 300, and the workpiece, preventing misalignment between the fixing component 210 and the workpiece due to tilting, but also avoids excessive wear of the height adjustment component 420 caused by long-term rigid force on one side.

[0081] In this embodiment, the supporting mechanism 100 includes a supporting member 110 and a limiting member 512. The top surface of the supporting member 110 forms a supporting portion. There are two limiting members 512, which are respectively provided at both ends of the supporting portion along the moving direction of the fixing member 210. The top surface of the limiting member 512 is flush with the supporting portion and has an upwardly protruding limiting portion, which is used to abut against the transfer mechanism 200.

[0082] Specifically, in this embodiment, the limiting member 512 is disposed at both ends of the bearing portion along the moving direction of the fixing member 210. Under normal conditions, the top surface of the limiting member 512 is flush with the bearing portion, which can ensure that there is no protruding structural obstruction when the fixing member 210 moves the workpiece along the bearing portion. That is, when the workpiece is transferred to the bearing portion or from the bearing portion to the processing equipment, both the fixing member 210 and the workpiece can move smoothly along the top surface of the bearing member 110, avoiding transfer jamming or workpiece collision caused by the protrusion of the limiting structure, and ensuring the continuity of the heavy workpiece transfer process.

[0083] When the fixing member 210 moves the workpiece to a preset position (such as the position on the support section for storing the workpiece), the limiting part of the limiting member 512 rises and becomes convex, abutting against the transfer mechanism 200 to limit the fixing member 210. This structure prevents the fixing member 210 from moving excessively due to inertia or driving error, avoiding the risk of the workpiece falling beyond the range of the support section, thus preventing equipment damage or safety accidents.

[0084] Furthermore, through the coordinated action of the limiting parts at both ends of the bearing part, the fixing part 210 can help position the workpiece at the preset reference position of the bearing part, providing an initial positioning reference for the subsequent alignment operation of the alignment mechanism 300, reducing the adjustment stroke of the alignment mechanism 300, improving alignment efficiency and accuracy, and avoiding rework due to the initial position deviation of the workpiece.

[0085] Furthermore, the two limiting members 512 are symmetrically arranged on both sides of the carrier section, thus adapting to the bidirectional transfer requirements of the carrier section. When the fixing member 210 moves the workpiece to the left end of the carrier section, the limiting part of the left limiting member 512 protrudes upward to achieve limiting. When the fixing member 210 moves the workpiece to the right end of the carrier section, the limiting part of the right limiting member 512 protrudes upward to complete the constraint. This allows for adaptation to bidirectional loading and unloading scenarios without additional adjustment of the limiting structure, enhancing the versatility of the equipment.

[0086] In this embodiment, there are two alignment mechanisms 300. The two alignment mechanisms 300 are respectively disposed on both sides of the bearing mechanism 100, and the alignment ends of the two alignment mechanisms 300 move in opposite directions.

[0087] The two alignment mechanisms 300 are located on both sides of the carrying mechanism 100, and their alignment ends move in opposite directions, which can directly adapt to the bidirectional operation process of the workpiece. When the transport vehicle takes material from the left-side material warehouse and the workpiece is sent to the left side area of ​​the carrying mechanism 100 via the transfer mechanism 200, the alignment end of the left-side alignment mechanism 300 can extend in a preset direction and directly align with the designated position of the workpiece.

[0088] Correspondingly, when the workpiece needs to be moved to the right-side processing equipment (such as a CNC machining center or CNC boring machine) and needs to be pre-aligned in the right-side area of ​​the bearing mechanism 100, the alignment end of the right-side alignment mechanism 300 can extend in the opposite direction to complete the positioning. There is no need to adjust the installation direction or movement trajectory of a single alignment mechanism 300, which avoids the time loss caused by the frequent switching of the unidirectional alignment mechanism 300 to adapt to bidirectional operations and improves the alignment efficiency in bidirectional loading and unloading scenarios.

[0089] Furthermore, the dual-sided alignment mechanism 300 and the bidirectional transfer mechanism 100 form a combined structure. When a workpiece is transferred from the left-side storage area to the carrier mechanism 100 via the forks 510, the left-side alignment mechanism 300 can simultaneously complete the alignment without waiting for the workpiece to be transferred to the center of the carrier mechanism 100. Similarly, before the workpiece is transferred to the right-side processing equipment, the right-side alignment mechanism 300 can pre-align it on the right side of the carrier mechanism 100, achieving parallel operation of transfer and alignment, and reducing process waiting time.

[0090] Meanwhile, the symmetrical layout of the two alignment mechanisms 300 does not require additional expansion of the volume of the bearing mechanism 100. Together with the bidirectional limiting of the bearing part and the bidirectional movement of the transfer mechanism 200, it forms a complete bidirectional operation system, which further improves the overall integration of the equipment and avoids occupying workshop space due to the addition of additional alignment equipment. Ultimately, it realizes bidirectional picking and delivery and bidirectional alignment of heavy workpieces, replacing manual alignment operations, thereby reducing labor costs and safety hazards, and improving the automation level of the production system.

[0091] In this embodiment, the alignment mechanism 300 includes a drive mechanism and an alignment rod 310. The drive mechanism is located below the support portion. The alignment rod 310 is drively connected to the drive mechanism. The support portion is provided with an insertion groove. A first moving part 111 is provided on the bottom side wall of the insertion groove. The fork 510 is disposed in the insertion groove, and a second moving part 511 is provided on the side wall of the fork 510.

[0092] Specifically, in this embodiment, the alignment rod 310 is connected to the drive mechanism and forms an alignment end at the end of the alignment rod 310 away from the drive mechanism. The rod-shaped alignment rod 310 can extend precisely to the specified alignment position of the workpiece. Especially for specific reference points such as the edge and positioning hole of large workpieces, the alignment rod 310 can penetrate into the gap between the workpiece and the bearing part or the specified reference area through its slender structure, avoiding the inability to adapt to the workpiece structure due to the excessive size of the alignment component.

[0093] Furthermore, in this embodiment, the drive mechanism indirectly acts on the workpiece through the alignment rod 310. The length and diameter of the alignment rod 310 can be adjusted to meet the alignment requirements of workpieces of different specifications without requiring modification to the drive mechanism itself, demonstrating excellent applicability. The transmission structure formed by the drive mechanism and the alignment rod 310 can stably transmit the driving force of the drive mechanism to the alignment end, thereby ensuring that the correction force applied to the heavy workpiece by the alignment end is uniform and controllable, avoiding localized deformation of the workpiece due to direct drive action.

[0094] Furthermore, in this embodiment, the drive mechanism is located below the support unit, eliminating the need to occupy the space above the support unit. This ensures sufficient space is reserved above the support unit for workpiece placement and the movement of the transfer mechanism 200. This structure avoids restricting workpiece placement due to the drive component occupying the support space, prevents collisions and wear between heavy workpieces and the drive mechanism during transport, and mitigates the risk of workpieces falling and damaging the drive component. This ensures the operational safety and service life of the core components of the alignment mechanism 300.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
