Description

Technical Field

[0001] This invention relates to the field of flywheel housing stacking and conveying technology, and in particular to a roadway stacker crane for stacking and conveying flywheel housings. Background Technology

[0002] The flywheel housing is a key basic component of automobiles, construction machinery, and internal combustion engine powertrains. It is installed between the engine and the transmission to connect the engine and the transmission, house the flywheel and clutch assembly, bear torque loads and vibration impacts, and ensure the coaxiality of the crankshaft and the transmission input shaft. It also provides sealing protection, heat dissipation, and installation positioning functions. Its machining accuracy and structural integrity directly affect the power transmission efficiency and the reliability of the vehicle operation.

[0003] In the continuous production process of flywheel housing, including casting, machining, cleaning, and inspection, workpieces need to be transferred between multiple machines and temporarily stacked. Currently, the industry commonly uses a combination of belt conveyors, roller conveyors, gantry robots, or manual transfer. Stacking is mostly achieved using simple pallets, racks, or positioning posts to achieve single or multi-layer stacking. After the workpieces are discharged from the previous process equipment, they are transferred to the next workstation via conveyor lines, and then manually or by robots, they are placed onto pallets or racks to complete the stacking.

[0004] Flywheel housings are mostly irregular thin-walled housings. Existing conveying and stacking methods cannot adapt to flywheel housings of different specifications. The conveying process is prone to deviation and jamming, and the positioning consistency is poor, which affects the loading and unloading and processing accuracy. Manual handling and placement are inefficient and labor-intensive, and are difficult to match the cycle time of automated production lines. Summary of the Invention

[0005] The technical problem this invention aims to solve is that existing conveying and stacking methods cannot adapt to flywheel housings of different specifications. The conveying process is prone to deviation and jamming, resulting in poor positioning consistency and affecting loading, unloading, and processing accuracy. Meanwhile, manual handling and placement are inefficient, labor-intensive, and difficult to match the pace of automated production lines.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a stacker crane for stacking and conveying flywheel housings in a roadway, including a main frame, the main frame having a top-mounted storage groove, a top lifting seat being provided at the upper end of the main frame, an electrically controlled lifting frame being movably installed inside the top-mounted storage groove, and an electrically controlled built-in locking mechanism and an optical positioning module being installed at the upper end of the top lifting seat.

[0007] The top lifting seat has a downward-protruding side guide plate on its outer side, and the side guide plate is located on the outer side of the main frame.

[0008] The upper end of the electrically controlled lifting frame is movably connected to the lower surface of the top lifting seat.

[0009] Both the lower surface of the top lifting seat and the bottom surface of the top storage groove are equipped with translation guide rails that cooperate with the electrically controlled lifting frame.

[0010] The electrically controlled lifting frame includes a scissor lift frame, adjustable sliders movably installed at the upper and lower ends of the scissor lift frame, and electrically controlled support rods installed at the ends of the translation guide rails.

[0011] The electrically controlled built-in locking mechanism includes an electrically controlled adjustment plate movably mounted on the top lifting seat, an end mounting rod fixed to the upper end of the electrically controlled adjustment plate, a first electrically controlled telescopic arm and a second electrically controlled telescopic arm fitted onto the end mounting rod via an end connecting ring, and an embedded magnetically controlled flipping bracket hinged to the end sides of the first electrically controlled telescopic arm and the second electrically controlled telescopic arm.

[0012] The first and second electrically controlled telescopic arms have the same structure, both including a flip control arm with an end connecting ring at the end, an embedded internal telescopic support rod inserted into the flip control arm, an end extension arm axially fixed to the extended end of the embedded internal telescopic support rod, a bottom adjustment slider fixed to the lower end of the flip control arm, and an electrically controlled gear installed inside the bottom adjustment slider.

[0013] The top lifting seat has an arc-shaped guide opening inside that cooperates with the bottom adjusting slider, and the inner wall of the arc-shaped guide opening has an arc-shaped tooth groove that meshes with the electric control gear.

[0014] The upper surface of the end extension arm is provided with a top storage slot for mounting an embedded magnetically controlled flip bracket. The embedded magnetically controlled flip bracket includes a flip pressing plate hinged to the upper opening of the top storage slot, an electromagnet mounted on the bottom surface of the top storage slot, and an iron spring for controlling the reset of the flip pressing plate.

[0015] A pressure sensing module is installed on the outer surface of the flip-over extrusion plate.

[0016] The beneficial effects of this invention are: (1) The present invention achieves precise positioning of the flywheel housing by setting up an optical positioning module. Combined with the horizontal and height adjustment of the electric lifting frame and the angle and extension adjustment of the electric built-in locking mechanism, it can adapt to irregular thin-walled flywheel housings of different specifications, effectively solving the problems of easy displacement, jamming and poor positioning consistency of existing equipment conveying and stacking, and improving the accuracy of loading and unloading and processing. (2) The equipment is fully electrically controlled and automated, which replaces manual handling and placement, greatly reduces the intensity of manual labor, improves production efficiency, matches the cycle requirements of automated production lines, and at the same time reduces the impact damage to the flywheel housing caused by manual operation, thus reducing the defect rate. (3) The electrically controlled built-in locking mechanism is equipped with a pressure sensing module and an embedded magnetic control flipping bracket, which can detect the clamping pressure in real time and achieve flexible clamping, avoiding excessive clamping pressure that could cause deformation of the flywheel housing structure or surface damage, and ensuring the structural integrity of the workpiece. (4) The electric control lifting frame of the equipment adopts a scissor structure with a translation guide rail, which has high stability in lifting and horizontal adjustment. The top lifting seat is equipped with a side guide plate, which further improves the stability of equipment operation and reduces the equipment failure rate. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figures 1 to 3 The stacker crane shown is used for stacking and conveying flywheel housings in a roadway. It includes a main frame 1, which serves as the overall support foundation for the equipment. The main frame 1 has a top-mounted storage groove 2 in the middle for storing an electrically controlled lifting frame 5. A top lifting seat 3 is movably mounted on the upper end of the main frame 1. The outer side of the top lifting seat 3 is integrally formed with a downwardly protruding side guide plate 8. The side guide plate 8 is set against the outer side wall of the main frame 1 and plays a guiding and limiting role during the lifting and lowering process of the top lifting seat 3, so as to prevent the top lifting seat 3 from horizontally deviating and improve the operational stability of the equipment.

[0025] The top of the lifting seat 3 is also fixedly installed with an optical positioning module 7 and an electrically controlled built-in locking mechanism 6. The electrically controlled built-in locking mechanism 6 adopts a multi-degree-of-freedom electrically controlled mechanical claw structure, which can realize opening and closing and angle adjustment. It is used for gripping, separating and initially positioning the flywheel housing. The optical positioning module 7 adopts a combination structure of visual positioning sensor and laser positioning instrument, which can detect the position, specifications and placement angle of the flywheel housing in real time, and transmit the positioning signal to the electronic control system of the equipment, providing accurate positioning basis for the action of each actuator.

[0026] An electrically controlled lifting frame 5 is movably installed inside the top-mounted storage recess 2. The upper end of the electrically controlled lifting frame 5 is movably connected to the lower surface of the top lifting seat 3. Both the lower surface of the top lifting seat 3 and the inner bottom surface of the top-mounted storage recess 2 are fixedly installed with translation guide rails 9 by bolts. The electrically controlled lifting frame 5 slides with the translation guide rails 9 to achieve horizontal position adjustment. The electrically controlled lifting frame 5 includes a scissor lift frame 51, adjusting sliders 52, and electrically controlled support rods 53. There are four sets of adjusting sliders 52, with two sets of adjusting sliders 52 movably installed on the upper end of the scissor lift frame 51. Two additional sets of adjusting sliders 52 are movably installed at the lower end of the scissor lift frame 51. The upper adjusting slider 52 cooperates with the translation guide rail 9 on the lower surface of the top lifting seat 3, and the lower adjusting slider 52 cooperates with the translation guide rail 9 on the bottom surface of the top storage groove 2. The cylinder end of the electric control strut 53 is hinged to the end of the translation guide rail 9, and the telescopic rod end is hinged to the middle hinge point of the scissor lift frame 51. When the electric control strut 53 extends or retracts, it drives the scissor lift frame 51 to expand or contract, thereby realizing the height adjustment of the top lifting seat 3 to meet the loading, unloading and stacking requirements of different height workstations.

[0027] An electrically controlled built-in locking mechanism 6 is movably installed at the upper middle position of the top lifting seat 3. The electrically controlled built-in locking mechanism 6 includes an electrically controlled adjustment plate 61, an end mounting rod 62, a first electrically controlled telescopic arm 64, a second electrically controlled telescopic arm 65, and an embedded magnetically controlled flipping bracket 66. The electrically controlled adjustment plate 61 is movably installed on the top lifting seat 3 via bearings and is driven to rotate by a servo motor. The end mounting rod 62 is vertically welded to the center position of the upper end face of the electrically controlled adjustment plate 61. The first electrically controlled telescopic arm 64 and the second electrically controlled telescopic arm 65 are symmetrically arranged about the end mounting rod 62, and the ends of both are fitted onto the end mounting rod 62 through end connecting rings 63, allowing them to rotate around the end mounting rod 62.

[0028] The first electrically controlled telescopic arm 64 and the second electrically controlled telescopic arm 65 have completely identical structures, both including a flip control arm 641, an embedded internal telescopic support rod 642, an end extension arm 643, a bottom-mounted adjusting slider 644, and an electrically controlled gear 645. One end of the flip control arm 641 is provided with an end connecting ring 63, and a telescopic cavity is opened inside. The embedded internal telescopic support rod 642 is inserted into the telescopic cavity of the flip control arm 641 and is driven by a built-in electric push rod to achieve telescopic movement. The end extension arm 643 is axially fixed to the extended end of the embedded internal telescopic support rod 642, and the overall length is adjusted with the telescopic movement of the embedded internal telescopic support rod 642 to adapt to flywheel housings of different outer diameters. The bottom adjustment slider 644 is welded to the lower end of the flip control arm 641. The electric control gear 645 is installed inside the bottom adjustment slider 644 via a rotating shaft and is driven by a micro servo motor. The top lifting seat 3 has an arc-shaped guide opening 10 that cooperates with the bottom adjustment slider 644. The bottom adjustment slider 644 can slide in the arc-shaped guide opening 10. The inner wall of the arc-shaped guide opening 10 has an arc-shaped tooth groove 11 that meshes with the electric control gear 645. When the electric control gear 645 rotates, it rolls along the arc-shaped tooth groove 11, driving the bottom adjustment slider 644 to slide in the arc-shaped guide opening 10, thereby realizing the adjustment of the opening angle of the first electric telescopic arm 64 and the second electric telescopic arm 65 to meet the clamping requirements of flywheel housings with different opening sizes.

[0029] The upper surface of the end extension arm 643 is provided with a top storage groove 12. An embedded magnetically controlled flipping bracket 66 is installed in the top storage groove 12. The embedded magnetically controlled flipping bracket 66 includes a flipping compression plate 661, an electromagnet 662, and an iron spring 663. One end of the flipping compression plate 661 is hinged to the upper opening of the top storage groove 12, which can realize the flipping action. The electromagnet 662 is fixedly installed on the inner bottom surface of the top storage groove 12 by bolts. One end of the iron spring 663 is connected to the upper end of the electromagnet 662, and the other end is connected to the inner side wall of the flipping compression plate 661. The iron spring 663 is an elastic reset component. When the electromagnet 662 is de-energized, it drives the flipping compression plate 661 to reset to the top storage groove 12. When the electromagnet 662 is energized, it generates magnetic force to attract the iron spring 663, which drives the flipping compression plate 661 to flip around the hinge point and extend out of the top storage groove 12, thereby realizing the compression and locking of the flywheel housing. A pressure sensing module 13 is attached to the outer surface of the flip-over extrusion plate 661. The pressure sensing module 13 is a thin-film pressure sensor that detects the clamping pressure between the flip-over extrusion plate 661 and the flywheel housing in real time and transmits the pressure signal to the electronic control system. When the pressure reaches the preset threshold, the electronic control system controls the electromagnet 662 to stop magnetizing and the embedded internal telescopic support rod 642 to stop extending and retracting, so as to avoid excessive clamping pressure causing structural deformation or surface damage to the flywheel housing.

[0030] Equipment working principle and working process This equipment is based on centralized control of an electronic control system. It achieves precise positioning of the flywheel housing through the optical positioning module 7, and, in conjunction with the horizontal and height adjustment of the electronically controlled lifting frame 5, the angle, extension, and flexible clamping adjustment of the electronically controlled built-in locking mechanism 6, and the gripping and separating actions, it realizes the automated stacking and conveying of flywheel housings of different specifications. The entire process requires no manual intervention. The specific working process is as follows: Material loading and positioning: After the equipment is started, the electrical control system controls the movement of the electrical control support rod 53 of the electrically controlled lifting frame 5, which drives the scissor lift frame 51 to unfold and adjust the top lifting seat 3 to match the height of the previous process discharge station. At the same time, the electrically controlled lifting frame 5 slides horizontally along the translation guide rail 9 through the adjusting slider 52 to adjust the horizontal position of the top lifting seat 3. The optical positioning module 7 scans the flywheel housing of the previous process discharge station in real time, detects the specifications, position and placement angle of the flywheel housing, and transmits the positioning signal to the electrical control system. Clamping and locking: The electronic control system controls the rotation of the electronically controlled adjusting disc 61 of the electronically controlled built-in locking mechanism 6, adjusting the initial angle of the first electronically controlled telescopic arm 64 and the second electronically controlled telescopic arm 65. Simultaneously, it controls the rotation of the electronically controlled gear 645, which rolls along the arc-shaped tooth groove 11, causing the bottom-mounted adjusting slider 644 to slide within the arc-shaped guide opening 10. This achieves precise adjustment of the opening angle of the first electronically controlled telescopic arm 64 and the second electronically controlled telescopic arm 65, adapting to the opening size of the flywheel housing. Subsequently, the electronic control system controls the embedded internal... The telescopic support rod 642 extends, driving the end extension arm 643 to approach the inner wall of the flywheel housing. When the end extension arm 643 reaches the preset position, the electromagnet 662 is energized to generate magnetic force, attracting the iron spring 663 to drive the flipping extrusion plate 661 to flip and extend out of the top receiving groove 12, contacting the inner wall of the flywheel housing and achieving extrusion. The pressure sensing module 13 detects the clamping pressure in real time. When the pressure reaches the preset threshold, the electronic control system stops the relevant actions, completing the flexible clamping and locking of the flywheel housing to prevent workpiece displacement. Conveying and Stacking: After the flywheel housing is clamped and locked, the electrical control system controls the electrically controlled lifting frame 5 to move. Through the extension and retraction of the electrically controlled support rod 53 and the horizontal sliding of the adjusting slider 52, the top lifting seat 3 is adjusted to the height and horizontal position of the stacking station. At the same time, the electrically controlled adjusting plate 61 can rotate according to the stacking requirements to adjust the placement angle of the flywheel housing. After reaching the stacking station, the first electrically controlled telescopic arm 64 and the second electrically controlled telescopic arm 65 extend, pushing the flywheel housing to the designated position. Then, the electromagnet 662 is energized, and the iron spring 663... The flip-over extrusion plate 661 is reset to the top receiving slot 12, releasing the clamp on the flywheel housing. The flywheel housing is then placed in the designated position at the stacking station to complete a single stacking operation. Then, the first electrically controlled telescopic arm 64 and the second electrically controlled telescopic arm 65 retract, and the main frame 1 is driven to leave the gap at the bottom of the flywheel housing. If multi-layer stacking is required, the electronic control system repeats the above-mentioned feeding positioning, gripping and separating, clamping and locking, and conveying actions to accurately place the next flywheel housing on top of the already stacked workpieces, realizing multi-layer automated stacking. Material feeding and conveying: When the flywheel housing is stacked to the preset number of layers, the electronic control system controls the entire equipment to convey the stacked flywheel housing to the next process feeding station. The electronically controlled built-in locking mechanism 6 cooperates to place the stacked flywheel housing into the next process feeding station, completing the feeding. Then the equipment is reset and enters the next work cycle.
