Description

Technical Field

[0001] This invention relates to the field of processing equipment for large thin-walled elongated workpieces, and in particular to a flipping device for large thin-walled elongated workpieces. Background Technology

[0002] Large, thin-walled, elongated workpieces are very common in the aerospace and railway transportation industries. However, due to their low rigidity and easy surface damage, there has never been a perfect solution for the flipping step in the processing.

[0003] Currently, there are two main solutions for flipping large, thin-walled, long strip workpieces. One is to use a multi-worker cooperative method to flip the workpiece manually, which is obviously not suitable for today's automated production environment. The other is to use a special tooling fixture to constrain both ends of the workpiece, and then use a rotary motor to flip the workpiece in an automated flipping solution. However, because these large, thin-walled, long strip workpieces have low rigidity and are easily damaged, the solution of directly clamping the workpiece for flipping has problems such as high stress on the workpiece during the flipping process, difficulty in aligning the workpiece with the fixture, and easy damage to the clamping parts of the fixture. Summary of the Invention

[0004] In view of this, in order to solve the problem that direct clamping during the flipping of large, thin-walled, long strip workpieces can easily lead to damage to the clamping parts, embodiments of the present invention provide a flipping device for large, thin-walled, long strip workpieces.

[0009] Furthermore, the support drive assembly includes a support frame, multiple steering wheels, and a tilting drive mechanism. The outer frame assembly includes an outer support ring, which is installed inside the support frame, and the outer wall of the outer support ring is in rolling contact with the steering wheels. The tilting drive mechanism is connected to the outer support ring to drive the outer support ring to rotate.

[0010] Furthermore, the outer support ring has a toothed ring on its surface, and the flipping drive mechanism includes a flipping motor and a flipping gear. The flipping motor is connected to the flipping gear, and the flipping gear meshes with the toothed ring.

[0011] Furthermore, the outer frame assembly also includes a cuboid mounting frame, and the number of outer support rings is set to multiple, with each outer support ring arranged in parallel, and the mounting frame embedded between each outer support ring.

[0012] Furthermore, the vertical moving plate is horizontally positioned, and both ends of the vertical moving plate are slidably connected to the outer frame assembly.

[0013] Furthermore, the vertical moving plate is an L-shaped plate, and the horizontal moving plate is disposed inside the vertical moving plate and slidably connected to the inner wall of the vertical moving plate.

[0014] Furthermore, the vertical drive mechanism includes a four-screw transmission assembly, each of which includes a vertical drive motor and a screw, the vertical drive motor being connected to the screw, and the screw being connected to the vertical moving plate.

[0015] Furthermore, both the upper lateral drive mechanism and the lower lateral drive mechanism include two gear and rack transmission assemblies. Each gear and rack transmission assembly includes a lateral drive motor, a drive gear, and a rack.

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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] Please refer to Figure 1 and 2 The present invention provides a flipping device for a large thin-walled elongated workpiece, which is applied to the flipping process of a large thin-walled elongated workpiece 100 (hereinafter referred to as workpiece) during surface processing. It mainly includes two flipping mechanisms 1 and an auxiliary tray assembly 2.

[0037] Referring again to Figure 3, the two flipping mechanisms 1 are generally arranged opposite to each other, and the auxiliary tray assembly 2 is located between the two flipping mechanisms 1. Each flipping mechanism 1 includes a support drive assembly 11, an outer frame assembly 12, an outer moving assembly 13, and an inner moving assembly 14.

[0038] like Figure 4 and 5 As shown, the outer frame assembly 12 is rotatably mounted on the support drive assembly 11, and the support drive assembly 11 can drive the outer frame assembly 12 to rotate. Specifically, the support drive assembly 11 includes a support frame 111, multiple steering wheels 112, and a tilting drive mechanism. The support frame 111 is hollow in the middle and is generally formed by welding profiles. The shape of the support frame 111 is approximately U-shaped, and the bottom of the support frame 111 is generally directly fixed to the factory ground. Each steering wheel 112 is installed on the inner side of the support frame 111, and each steering wheel 112 is located on the same circumference. In this embodiment, the support frame 111 is a double-layer frame, and each steering wheel 112 is respectively arranged on two coaxial circumferences.

[0039] The outer frame assembly 12 includes an outer support ring 121 and a mounting frame 123. The outer support ring 121 has a circular outer wall and a rectangular inner hole in the middle. The outer support ring 121 is installed in the support frame 111, and the outer wall of the outer support ring 121 is in rolling contact with the steering wheel 112. Under the constraint of each steering wheel 112, the outer support ring 121 can rotate stably within the support frame 111.

[0040] The flipping drive mechanism is connected to the outer support ring 121 to drive the outer support ring 121 to rotate. Specifically, the surface of the outer support ring 121 is provided with a gear ring 122. The flipping drive mechanism includes a flipping motor 114 and a flipping gear 113. The flipping motor 114 and the flipping gear 113 are installed at the bottom of the support frame 111. The flipping motor 114 is connected to the flipping gear 113. The flipping gear 113 meshes with the gear ring 122. The flipping motor 114 drives the gear to rotate, thereby driving the gear ring 122 and the support ring 121 to rotate.

[0041] The external moving component 13 is installed inside the external frame component 12, specifically within the mounting frame 123. The mounting frame 123 is a cuboid frame, and it is embedded within the inner hole of the external support ring 121. Preferably, there are multiple external support rings 121; for example, in this embodiment, there are two external support rings 121 arranged in parallel, with the mounting frame 123 embedded between them.

[0042] like Figure 6 As shown, the outer moving component 13 mainly includes four vertical moving plates 131 and a vertical driving mechanism. The vertical moving plates 131 are horizontally arranged, and the four vertical moving plates 131 are arranged in a rectangle with two vertically opposite each other. The two vertically opposite vertical moving plates 131 are arranged close to the inner side of the mounting frame 123. The inner side of the mounting frame 123 is provided with two vertically arranged vertical guide rails 134. The two ends of the vertical moving plates 131 are respectively connected to the two vertical guide rails 134, so that the vertical moving plates 131 are slidably connected to the outer frame component 12, thereby allowing the vertical moving plates 131 to slide only vertically.

[0043] The vertical drive mechanism can drive the four vertical moving plates 131 to move vertically, causing two vertically opposite vertical moving plates 131 to move closer or further apart. Specifically, the vertical drive mechanism includes a four-screw 133 transmission assembly. Each screw 133 transmission assembly includes a vertical drive motor 132 and a screw 133. The vertical drive motor 132 is mounted on the mounting frame 123. The screw 133 is vertically arranged. The vertical drive motor 132 is connected to the screw 133. The nut of the screw 133 is connected to the vertical moving plate 131. Here, a connecting plate 135 is provided on the back of the vertical moving plate 131, and the nut of the screw 133 is connected through the connecting plate 135.

[0044] In some other embodiments, to reduce the number of motors and lower costs, and to reduce the size of the device, the vertical drive mechanism uses one motor to drive the two vertical moving plates 131. Specifically, the vertical drive mechanism includes a two-screw transmission assembly 133. Each screw transmission assembly 133 includes a vertical drive motor 132, a transmission belt, and two screws 133. The drive motor is connected to the transmission belt, which is connected to the two screws 133 respectively. The two screws 133 are connected to the two vertical moving plates 131 respectively. The two screws 133 connected by the transmission belt rotate in the same direction and at the same speed.

[0045] like Figure 7 As shown, the inner moving assembly 14 includes four horizontal moving plates 141, an upper horizontal driving mechanism, and a lower horizontal driving mechanism. Each horizontal moving plate 141 is slidably connected to a vertical moving plate 131, so that each horizontal moving plate 141 is horizontally arranged, and the four horizontal moving plates 141 are arranged in an approximately rectangular shape. Here, the vertical moving plate 131 is an L-shaped plate, and the horizontal moving plate 141 is disposed inside the vertical moving plate 131. The vertical moving plate 131 is provided with a horizontal guide rail 146, and the horizontal moving plate 141 is supported on the vertical moving plate 131 and slidably connected to the horizontal guide rail 146, so that the horizontal moving plate 141 can only move horizontally.

[0046] The transverse moving plate 141 is a C-shaped groove plate. The four transverse moving plates 141 are arranged horizontally opposite each other in pairs. The grooves of the two horizontally opposite transverse moving plates 141 are arranged opposite each other, and the two horizontally opposite transverse moving plates 141 form a clamping structure.

[0047] The upper lateral drive mechanism is connected to the two upper lateral moving plates 141 respectively to drive the two upper lateral moving plates 141 to move laterally, and the lower lateral drive mechanism is connected to the two lower lateral moving plates 141 respectively to drive the two lower lateral moving plates 141 to move laterally.

[0048] Specifically, both the upper lateral drive mechanism and the lower lateral drive mechanism include two gear and rack transmission assemblies 144. Each gear and rack transmission assembly 144 includes a lateral drive motor 142, a drive gear 143, and a rack 144. The lateral drive motor 142 is connected to the drive gear 143, and the rack 144 is mounted on the lateral moving plate 141 and meshes with the drive gear 143.

[0049] Preferably, in order to reduce the number of motors, both the upper lateral drive mechanism and the lower lateral drive mechanism can be driven by a single motor. That is, each lateral drive motor 142 is connected to the rotating shaft 145 through a coupling, and the two drive gears 143 are mounted on the rotating shaft 145. The lateral drive motor 142 can drive the two drive gears 143 to rotate simultaneously, thereby driving the two gears to move and causing the lateral moving plate 141 to move laterally, realizing extension and retraction.

[0050] like Figure 8 and 9 As shown, the auxiliary tray assembly 2 includes an auxiliary tray 21, which supports the workpiece 100 to be processed. The ends of the auxiliary tray 21 and the universal tray 200 are adapted to the two horizontally opposite transverse moving plates 141, such that the two ends of the auxiliary tray 21 and the universal tray 200 can be respectively inserted into the two upper transverse moving plates 141 and the two lower transverse moving plates 141 of the two flipping mechanisms 1.

[0051] It should be noted that the universal pallet 200 mentioned in this application refers to the pallet used to support the workpiece 100 in the corresponding production line, and the universal pallet 200 may vary in different production scenarios. Generally, both the auxiliary pallet 21 and the universal pallet 200 are provided with two parallel positioning rods 25 at both ends, and the two positioning rods 25 are adapted to the slots of the two horizontally opposite transverse moving plates 141. As in this embodiment, both the auxiliary pallet 21 and the universal pallet 200 are frame structures formed by welding square tubes, and the cross-sectional shape of the square tubes is adapted to the slot shape of the transverse moving plates 141.

[0052] In addition, the auxiliary tray assembly 2 also includes a flexible support 24 disposed on the auxiliary tray 21, and a plurality of pressing components disposed on both sides of the auxiliary tray 21. Each pressing component includes a rotary cylinder 22 and a rotary pressing cylinder 23. The rotary cylinder 22 is mounted on the side of the auxiliary tray 21, and the rotary pressing cylinder 23 is mounted on the rotary cylinder 22. The rotary cylinder 22 can drive the rotary pressing cylinder 23 to rotate vertically, so that the rotary pressing cylinder 23 remains flush with the auxiliary tray 21 when not in use, and rotates upward and extends when needed. The rotary pressing cylinder 23 can rotate toward the inside of the auxiliary tray 21 and press down vertically, thereby entering above the auxiliary tray 21 to press down the universal tray 200.

[0053] The process of processing workpiece 100 using this large, thin-walled, elongated workpiece flipping device is as follows:

[0054] In its initial state, the auxiliary tray assembly 2 is positioned precisely between the two flipping mechanisms 1;

[0055] First, the two upper transverse moving plates 141 are driven to extend by the upper transverse driving mechanism, so that the two ends of the auxiliary tray 21 are respectively inserted into the two upper transverse moving plates 141 of the two flipping mechanisms 1, and the auxiliary tray 21 is clamped; the AGV trolley places the universal tray 200 containing the workpiece 100 on the tray frame, so that the universal tray 200 containing the workpiece 100 is located below the auxiliary tray 21.

[0056] Then, as Figure 1 As shown, the outer frame assembly 12 is driven to rotate 90° by the flipping drive mechanism, so that the auxiliary tray 21 is set vertically, and the robot processes the upper surface of the workpiece 100; after the upper surface of the workpiece 100 is processed, the outer frame assembly 12 is driven to rotate 90° in the opposite direction by the flipping drive mechanism, returning to the initial position.

[0057] Subsequently, the two lower transverse moving plates 141 are extended by the lower transverse driving mechanism, so that the two ends of the auxiliary tray 21 are respectively inserted into the two lower transverse moving plates 141 of the two flipping mechanisms 1, clamping the universal tray 200. Then, the four vertical moving plates 131 are driven to move closer together by the vertical driving mechanism, causing the universal tray 200 and the auxiliary tray 21 to move closer to each other, jointly constraining the workpiece 100 between the two trays. Here, the rotary pressing cylinder 23 can also be extended by the rotary pressing cylinder 22, and the back of the universal tray 200 can be pressed by the rotary pressing cylinder 23, fastening the auxiliary tray 21 and the universal tray 200 together. The flexible support 24 on the rotary pressing cylinder 23 and the auxiliary tray 21 work together to ensure that the workpiece 100 will not slip from the auxiliary tray 21 and the universal tray 200 during the flipping process.

[0058] Next, the outer frame assembly 12 is rotated 180° by the flipping drive mechanism, causing the workpiece 100 to flip over. After flipping, the two transverse moving plates 141 are retracted by the upper transverse drive mechanism, causing the two ends of the auxiliary tray 21 to exit from the two transverse moving plates 141, releasing the auxiliary tray 21 and allowing it to be stably placed on the tray frame; as... Figure 2 As shown, the flipping drive mechanism drives the outer frame assembly 12 to rotate 90°, and the robot processes the lower surface of the workpiece 100.

[0059] After the lower surface of the workpiece 100 is processed, the flipping drive mechanism drives the outer frame assembly 12 to rotate 90° in the opposite direction. The upper transverse drive mechanism drives the two transverse moving plates 141 to extend, so that the two ends of the auxiliary tray 21 are respectively inserted into the two transverse moving plates 141 of the flipping mechanism 1, and the auxiliary tray 21 is clamped.

[0060] Subsequently, the general-purpose tray 200 and the auxiliary tray 21 clamp the workpiece 100 again, and the flipping drive mechanism drives the outer frame assembly 12 to rotate 180° (opposite to the previous 180° rotation direction), so that the upper surface of the workpiece 100 faces.

[0061] Finally, the vertical drive mechanism drives the four vertical moving plates 131 to move away from each other in pairs, separating the universal pallet 200 from the auxiliary pallet 21. The lower horizontal drive mechanism drives the two lower horizontal moving plates 141 to retract, causing the two ends of the auxiliary pallet 21 to exit from the two lower horizontal moving plates 141 of the two flipping mechanisms 1. The universal pallet 200 is then placed back on the pallet rack, and the workpiece 100 is supported on the universal pallet 200 again. The AGV can then transfer the universal pallet 200 and the workpiece 100 on it together.

[0062] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0063] Where there is no conflict, the embodiments and features described above can be combined with each other. The above descriptions are merely preferred embodiments of the present invention and are not intended to limit the invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
