Abstract
Description
Technical Field
[0001] This invention relates to the field of aero-engine assembly, specifically to an automatic docking and transport device and method for a floating core engine. Background Technology
[0002] As the core component of an aero-engine, the core engine needs to be transferred and mounted between workstations after assembly. Therefore, its transportation and connection become key factors affecting the quality and efficiency of engine assembly.
[0003] In existing technologies, the transport and connection of the core machine mainly relies on hoisting. This method first requires hoisting the intermediate casing of the core machine to the corresponding assembly station using hoisting fixtures, then assembling the various components of the core machine, and finally transferring the assembled core machine using specialized hoisting tools. Subsequently, manual docking is required to connect the core machine to the assembly auxiliary equipment of the next workstation. This method suffers from drawbacks such as low docking accuracy, high docking difficulty, and long assembly time, which seriously affects the assembly efficiency of the core machine. Furthermore, this method is overly reliant on manual labor, increasing the workload of workers. In addition, besides the core machine bracket, this method requires specialized hoisting fixtures with many redundant components, which is also detrimental to on-site management.
[0004] For example, Chinese invention patent CN103056653B discloses a bracket-type core machine assembly method. This method, in addition to a core machine assembly bracket, also uses specialized lifting tools such as a universal lifting tool and a core machine lifting tool. In step one, the universal lifting tool is used to install the intermediate housing onto the support platform of the core machine assembly bracket. Then, various components are assembled on the support platform. The core machine lifting tool used in this method includes structures such as a mandrel. In step six, after the core machine assembly is completed, a crane is used to lift the core machine lifting tool, and the mandrel on the lower side of the lifting tool is slowly inserted into the core machine, with the lower end of the mandrel connected to a mandrel nut. Then, in step seven, the connecting screws between the intermediate housing and the support platform of the core machine assembly bracket are removed, and the core machine is lifted onto an assembly vehicle using the core machine lifting tool. This method suffers from problems such as numerous redundant components and difficulties in on-site management. Furthermore, the use of a specially designed core machine lifting tool for core machine transfer is not conducive to the docking of subsequent processes with related assembly auxiliary equipment. Summary of the Invention
[0005] The purpose of this invention is to provide a floating core machine automatic docking and transportation device and method, which uses a positioning support frame, a floating platform and an AGV trolley to realize the automatic assembly and positioning of the core machine and the transfer and docking between processes, thereby improving work efficiency.

[0012] The floating platform includes a platform frame and an upper end plate. The platform frame is mounted on the lifting mechanism. The upper end plate is located at the top of the platform frame and has multiple rolling ball bearings arranged on it. Limiting plates are provided around the upper end plate. A load-bearing adjustment plate is located on the upper end plate and supported by the rolling ball bearings. The load-bearing adjustment plate is limited by the limiting plates. A positioning support plate at the top of the positioning support frame is located on the load-bearing adjustment plate. Each corner of the load-bearing adjustment plate is provided with a locking pin that connects to the upper end plate.
[0013] The inner side of the limiting plate is provided with a buffer pad; the upper side of the bearing adjustment plate is provided with a bearing limiting block, and the positioning support plate is located between the two bearing limiting blocks.
[0014] The floating platform includes a platform frame, which is mounted on the lifting mechanism. The upper end of the platform frame is provided with an upper plate, and the upper side of the upper plate is provided with an X-axis adjustment mechanism and an X-axis sliding plate driven to move by the X-axis adjustment mechanism. The upper side of the X-axis sliding plate is provided with a Y-axis adjustment mechanism and a Y-axis sliding plate driven to move by the Y-axis adjustment mechanism. The upper side of the Y-axis sliding plate is provided with a rotation mechanism and a load-bearing adjustment plate driven to rotate by the rotation mechanism.
[0015] The X-axis adjustment mechanism includes an X-axis lead screw driven to rotate by an X-axis motor and an X-axis nut fitted on the X-axis lead screw. The X-axis nut is provided with an X-axis connecting seat and is fixedly connected to the X-axis slide plate. The two sides of the X-axis slide plate are slidably connected to the two sides of the upper end plate of the frame.
[0016] The Y-axis adjustment mechanism includes a Y-axis lead screw driven to rotate by a Y-axis drive component and a Y-axis nut fitted on the Y-axis lead screw. The Y-axis nut is provided with a Y-axis connecting seat, and the Y-axis connecting seat is fixedly connected to the Y-axis sliding plate. The two sides of the Y-axis sliding plate are slidably connected to the two sides of the X-axis sliding plate.
[0017] The rotating mechanism includes a rotary adjustment motor, a worm gear, and a worm wheel, wherein the worm gear meshes with one side of the worm wheel and is driven to rotate by the rotary adjustment motor, and the worm wheel is fixedly connected to the load-bearing adjustment plate.
[0018] A method for automatically docking a transport device with a floating core machine includes the following steps:
[0019] Step 1: The AGV trolley transports the positioning support frame to the core machine assembly station. Then, the fixed connection between the floating platform and the positioning support frame is released. Then, the lifting mechanism descends and drives the positioning support frame to descend so that the positioning pin sleeves at the lower ends of the positioning legs on both sides cooperate with the corresponding positioning pin shafts on the assembly station for positioning.
[0020] Step 2: The lifting mechanism continues to descend, causing the floating platform to detach from the positioning support frame. Then, the AGV trolley, along with the lifting mechanism, exits the positioning support frame.
[0021] Step 3: Fix the intermediate unit of the core machine to the positioning support plate at the upper end of the positioning support frame, and then complete the assembly of the other units of the core machine.
[0022] Step 4: After the core machine is assembled, the AGV trolley moves back into the positioning support frame. Then, the lifting mechanism is activated to lift the positioning support frame and the core machine together until the positioning pin sleeve is separated from the positioning pin shaft by the set distance. Then, the floating platform is reconnected to the positioning support frame.
[0023] Step 5: The AGV trolley moves the core machine to the next assembly station. After the core machine is in place, the AGV trolley automatically locks. Then, the flexible docking between the core machine and the auxiliary equipment of the next assembly station is achieved by adjusting the load adjustment plate on the floating platform.
[0024] Step 6: After docking is completed, the core machine is disconnected from the positioning support frame. Then, the lifting mechanism drives the positioning support frame to descend and detach from the core machine. The AGV then returns to its original position to wait.
[0025] The advantages and positive effects of this invention are as follows:
[0026] 1. This invention utilizes a positioning support frame, a floating platform, and an AGV (Automated Guided Vehicle) to achieve automatic assembly and positioning of the core machine and inter-process transfer. After the AGV moves to the core machine assembly station, it uses the positioning pins at the lower ends of the positioning legs on both sides of the positioning support frame to cooperate with the corresponding positioning pins on the core machine assembly station for precise positioning. After the core machine is assembled, the AGV moves back into the positioning support frame and uses a lifting mechanism to lift the positioning support frame and the core machine together and transfer them to the next process assembly station. After moving into position, the floating platform is used to achieve flexible docking between the core machine and the auxiliary equipment of the next process assembly station. The entire process greatly reduces the degree of manual intervention and improves work efficiency and automation level.
[0027] 2. This invention integrates a floating platform onto an AGV (Automated Guided Vehicle). When errors occur on-site, the floating platform can be used for timely adjustment to eliminate them, thereby ensuring the accurate positioning of the core machine at the assembly station and smooth docking with auxiliary equipment at the next assembly station. Furthermore, this invention allows for the selection of a manually or automatically adjustable floating platform structure according to actual needs, making it more flexible and convenient to use. The manually adjustable floating platform utilizes rolling ball bearings to support the load-bearing adjustment plate for horizontal X and Y direction rotation and vertical Z direction adjustment, thereby achieving the position adjustment of the core machine. This structure is simple and compact, facilitating manual on-site operation. The automatically adjustable floating platform can automatically achieve the position adjustment of the core machine, thereby further improving the automation level of this invention.

Detailed Implementation
[0040] The invention will now be described in further detail with reference to the accompanying drawings.
[0041] like Figures 1-11As shown, the present invention includes a positioning support frame 2, a floating platform 4, a lifting mechanism 3, and an AGV trolley 6. The lifting mechanism 3 is mounted on the AGV trolley 6, and the floating platform 4 is mounted on the lifting mechanism 3. The positioning support frame 2 includes an upper positioning support plate 203, and the lower side of the positioning support plate 203 is supported by the floating platform 4. The upper side of the positioning support plate 203 carries the core machine 1. Positioning legs 201 are provided on both sides of the positioning support plate 203, and the lower end of each positioning leg 201 is equipped with a mounting bracket for the core machine. The positioning pin sleeve 202 is matched with the positioning pin shaft 5 at the workstation. The floating platform 4 is provided with a load-bearing adjustment plate 403 with X-axis movement freedom, Y-axis movement freedom and Z-axis rotation freedom. The positioning support plate 203 at the upper end of the positioning support frame 2 is located on the load-bearing adjustment plate 403. In addition, the width of the positioning legs 201 on both sides is greater than the total width of the AGV trolley 6 to avoid collision and interference with the AGV trolley 6 during the connection process, while ensuring that the adjustment needs of the load-bearing adjustment plate 403 on the floating platform 4 are met.
[0042] The present invention includes the following steps in operation:
[0043] Step 1: First, the AGV trolley 6 transports the positioning support frame 2 to the core machine assembly station. Then, the bolt connection between the floating platform 4 and the positioning support frame 2 is released. Then, the lifting mechanism 3 descends and drives the positioning support frame 2 to descend so that the positioning pin sleeves 202 at the lower end of the positioning legs 201 on both sides cooperate with the corresponding positioning pin shafts 5 on the core machine assembly station to achieve precise positioning.
[0044] Step 2: The lifting mechanism 3 continues to descend, causing the floating platform 4 to detach from the positioning support frame 2. Then, the AGV trolley 6, together with the lifting mechanism 3, exits the positioning support frame 2 and returns to its original position to wait.
[0045] Step 3: Fix the intermediate unit of core machine 1 to the positioning support plate 203 at the upper end of positioning support frame 2, and complete the assembly of other units in sequence according to the requirements of core machine assembly process manual. This assembly process is a well-known technology in the field.
[0046] Step 4: After the core machine 1 is assembled, the AGV trolley 6 moves back into the positioning support frame 2. Then the lifting mechanism 3 starts to lift the positioning support frame 2 and the core machine 1 together until the positioning pin sleeve 202 is separated from the positioning pin shaft 5 by a set distance (e.g., 15mm). Then the floating platform 4 is reconnected to the positioning support frame 2 by bolts.
[0047] Step 5: The AGV trolley 6 moves the core machine 1 to the next assembly station. After the core machine 1 is in place, the AGV trolley 6 automatically locks. This is a built-in function of the AGV trolley. Then, by adjusting the load adjustment plate 403 on the floating platform 4, the core machine 1 is flexibly connected with the auxiliary equipment of the next assembly station. The floating platform 4 can drive the core machine 1 to move horizontally in the X or Y direction and rotate around the vertical Z direction.
[0048] Step 6: After docking is completed, the core machine 1 is disconnected from the positioning support frame 2. Then, the lifting mechanism 3 drives the positioning support frame 2 to descend and separate from the core machine 1. Then, the AGV trolley 6 returns to its original position to wait.
[0049] The AGV vehicle 6 is a commercially available product, such as one that can be purchased from Siasun Robot & Automation Co., Ltd. The driving path of the AGV vehicle 6 is programmed and planned according to the needs of the site, which is a well-known technology in this field.
[0050] like Figures 4-6 As shown, the lifting mechanism 3 includes a lifting drive device 302, a drive gear 303, a drive lifting shaft 309, an intermediate gear 304, a driven gear 306, a driven lifting shaft 308, and a lifting plate 301, wherein... Figure 5 As shown, the driving gear 303 has a driving nut 310 in the middle, and the driving nut 310 is driven to rotate by the lifting drive device 302. The rotation of the driving nut 310 drives the driving gear 303 to rotate. The driving lifting shaft 309 is inserted into the driving nut 310, and the rotation of the driving nut 310 drives the driving lifting shaft 309 to move up and down. Figure 4 As shown, the driving gear 303 and each driven gear 306 are distributed along the circumference of the intermediate gear 304 and mesh with the intermediate gear 304. When the driving gear 303 rotates, it simultaneously drives each driven gear 306 to rotate via the intermediate gear 304. Figure 6 As shown, the driven gear 306 has a driven threaded sleeve 305 in the middle, and the driven lifting shaft 308 is inserted into the corresponding driven threaded sleeve 305. Rotation of the driven gear 306 drives the driven threaded sleeve 305 to rotate, thereby driving the driven lifting shaft 308 to move up and down. The upper ends of both the driving lifting shaft 309 and the driven lifting shaft 308 are connected to the lifting plate 301. This invention ensures that the driving lifting shaft 309 and the driven lifting shaft 308 move synchronously through the transmission ratio design of the driving gear 303, intermediate gear 304, and driven gear 306, thereby ensuring the smooth lifting of the lifting plate 301. Figure 3As shown, the floating platform 4 is mounted on the lifting plate 301 and is driven to rise and fall by the lifting plate 301. In this embodiment, the lifting height of the lifting mechanism 3 is 60mm, and its positioning accuracy is ±5mm.
[0051] like Figure 5 As shown, the lifting drive device 302 has a motor 3021, a first gear 3022, and a second gear 3023 inside its housing. The first gear 3022 meshes with the second gear 3023 and is driven to rotate by the motor 3021. The second gear 3023 is fitted onto the drive nut 310. The motor 3021 transmits torque through the first gear 3022 and the second gear 3023 to drive the drive nut 310 to rotate. The housing of the lifting drive device 302 has sufficient space for the lifting shaft 309 to move. The housing of the lifting drive device 302 is fixedly mounted on the AGV trolley 6, and the upper end of the housing has a drive bearing seat to support the rotation of the drive nut 310.
[0052] like Figure 4 As shown, the AGV trolley 6 is also provided with a driven bearing seat 307, and each driven threaded sleeve 305 is rotatably installed in the corresponding driven bearing seat 307.
[0053] like Figure 3 As shown, the lifting plate 301 is provided with an operation screen bracket 3011, and the operation screen bracket 3011 is provided with an operation screen 3012 at the upper end. The wiring of the operation screen 3012 passes through the operation screen bracket 3011 and is connected to the control module on the AGV trolley 6 to provide power. The motor 3021 is also connected to the control module through wiring. In this way, the operator can control the lifting action of the lifting mechanism 3 through the operation screen 3012.
[0054] like Figure 1 As shown, the positioning support plate 203 at the upper end of the positioning support frame 2 is provided with a workpiece connector 2031, and the workpiece connector 2031 can be fixed to the lower end of the core machine 1 by bolts, which can ensure the connection and prevent the core machine 1 from tipping over.
[0055] like Figures 1-11 As shown, the present invention can adopt a manually adjustable floating platform 4 structure or an automatically adjustable floating platform 4 structure according to actual needs.
[0056] Example 1:
[0057] like Figures 1-3 and Figure 7As shown, in this embodiment, the floating platform 4 is manually adjustable. The floating platform 4 includes a platform frame 401, an upper end plate 402, and a load-bearing adjustment plate 403. The platform frame 401 is mounted on the lifting plate 301 of the lifting mechanism 3. The upper end plate 402 is located at the upper end of the platform frame 401, and multiple rolling ball bearings 404 are arranged in a matrix on the upper end plate 402. L-shaped limiting plates 4021 are provided around the upper end plate 402. The load-bearing adjustment plate 403 is mounted on the upper end plate 402 and supported by the rolling ball bearings 404. The displacement of the load-bearing adjustment plate 403 is limited by the limiting plates 4021. Figure 1 As shown, the positioning support plate 203 at the upper end of the positioning support frame 2 is located on the bearing adjustment plate 403.
[0058] like Figure 7 As shown in this embodiment, each corner of the load-bearing adjustment plate 403 is provided with a locking pin 405 that is connected to the upper end plate 402 of the frame. When it is necessary to adjust the position of the load-bearing adjustment plate 403, the locking pin 405 is pulled upward and disengaged from the upper end plate 402 of the frame.
[0059] like Figure 7 As shown in this embodiment, the inner side of the limiting plate 4021 is provided with a buffer pad 4022 that plays a protective role.
[0060] like Figure 7 As shown, in this embodiment, the upper side of the load-bearing adjustment plate 403 is provided with a load-bearing limiting block 4031, such as... Figure 1 As shown, the positioning support plate 203 is disposed between two bearing limiting blocks 4031 to limit displacement.
[0061] The working principle of this embodiment is as follows:
[0062] After the AGV trolley 6 moves the assembled core machine 1 to the next assembly station, the AGV trolley 6 automatically locks. Then, the invention uses the floating platform 4 to achieve flexible docking between the core machine 1 and the auxiliary equipment of the next assembly station, wherein, for example... Figure 7 As shown, the load-bearing adjustment plate 403 is supported by rolling ball bearings 404 on the upper end plate 402 of the frame. When the locking pin 405 is pulled out, the operator can manually adjust the position of the load-bearing adjustment plate 403, thereby adjusting the position of the core machine 1. The adjustment range of the load-bearing adjustment plate 403 is limited to the range enclosed by the various limiting plates 4021. Thus, this embodiment can achieve a maximum movement of 30mm in the horizontal X or Y direction and a maximum rotation adjustment of 4° around the vertical Z direction.
[0063] In addition, during the descent of the positioning support frame 2 in step one above, the operator can also fine-tune the position of the positioning support frame 2 by adjusting the position of the bearing adjustment plate 403 according to the alignment of the positioning pin sleeve 202 and the corresponding positioning pin shaft 5. The positioning support plate 203 is located between the two bearing limit blocks 4031, which can ensure that the positioning support frame 2 can move with the fine adjustment of the bearing adjustment plate 403, thereby further ensuring the alignment of the positioning pin sleeve 202 and the corresponding positioning pin shaft 5.
[0064] Example 2:
[0065] like Figures 8-11 As shown, in this embodiment, the floating platform 4 adopts an automatic adjustment method. The floating platform 4 includes a platform frame 401, which is also mounted on the lifting plate 301 of the lifting mechanism 3. The upper end of the platform frame 401 is provided with an upper end plate 402, and the upper side of the upper end plate 402 is provided with an X-axis adjustment mechanism 406 and an X-axis sliding plate 407 driven to move by the X-axis adjustment mechanism 406. The upper side of the X-axis sliding plate 407 is provided with a Y-axis adjustment mechanism 408 and a Y-axis adjustment mechanism 408 driven to move by the Y-axis adjustment mechanism 406. Mechanism 408 drives the Y-axis sliding plate 409 to move. The upper side of the Y-axis sliding plate 409 is provided with a rotating mechanism 410 and a load-bearing adjustment plate 403 driven to rotate by the rotating mechanism 410. The positioning support plate 203 at the upper end of the positioning support frame 2 is located on the load-bearing adjustment plate 403. In this embodiment, a maximum movement of 30mm in the horizontal X or Y direction and a maximum rotation adjustment of 4° around the vertical Z direction can also be achieved. However, all of these adjustments are achieved automatically through the X-axis adjustment mechanism 406, the Y-axis adjustment mechanism 408, and the rotating mechanism 410.
[0066] like Figures 9-10 As shown, in this embodiment, the X-axis adjustment mechanism 406 includes an X-axis lead screw 4062 driven to rotate by an X-axis motor 4061 and an X-axis nut 4063 mounted on the X-axis lead screw 4062. The X-axis nut 4063 is provided with an X-axis connecting seat 4064 fixedly connected to the X-axis sliding plate 407. Rotation of the X-axis lead screw 4062 drives the X-axis nut 4063 to move, thereby driving the X-axis sliding plate 407 to move. Additionally, X-axis slide rails 4065 are provided on both sides of the upper end plate 402 of the frame, and X-axis sliders 4066 are provided on both sides of the X-axis sliding plate 407, respectively cooperating with the corresponding X-axis slide rails 4065, thereby achieving a sliding connection between the X-axis sliding plate 407 and the upper end plate 402 of the frame.
[0067] like Figure 9 and Figure 11As shown, in this embodiment, the Y-axis adjustment mechanism 408 includes a Y-axis lead screw 4083 driven to rotate by a Y-axis drive assembly and a Y-axis nut 4084 fitted on the Y-axis lead screw 4083. The Y-axis nut 4084 is provided with a Y-axis connecting seat 4085, and the Y-axis connecting seat 4085 is fixedly connected to the Y-axis sliding plate 409. Rotation of the Y-axis lead screw 4083 drives the Y-axis nut 4084 to move, thereby driving the Y-axis sliding plate 409 to move. Additionally, the X-axis sliding plate 407 has Y-axis slide rails 4086 on both sides, and the Y-axis sliding plate 409 has Y-axis sliders 4087 on both sides that respectively cooperate with the corresponding Y-axis slide rails 4086, thereby achieving a sliding connection between the Y-axis sliding plate 409 and the X-axis sliding plate 407.
[0068] like Figure 11 As shown, in this embodiment, the Y-axis drive assembly includes a Y-axis motor 4081 and a right-angle transmission box 4082. The Y-axis motor 4081 transmits torque through the right-angle transmission box 4082 to drive the Y-axis lead screw 4083 to rotate. Figure 8 As shown, the right-angle transmission box 4082 can prevent the rear end of the Y-axis motor 4081 from colliding and interfering with the positioning leg 201. The right-angle transmission box 4082 is a technology known in the art and is a commercially available product.
[0069] like Figure 9 As shown, in this embodiment, the rotating mechanism 410 includes a rotating adjustment motor 4101, a worm 4102, and a worm wheel 4103. The worm 4102 and the worm wheel 4103 mesh on one side and are driven to rotate by the rotating adjustment motor 4101. The worm wheel 4103 is fixedly connected to the bearing adjustment plate 403. The rotation of the worm 4102 drives the worm wheel 4103 to rotate, thereby driving the bearing adjustment plate 403 to rotate and adjust the angle.
