Description

Technical Field

[0001] The present invention relates to a feeding device for flanging of a slotted bushing, belonging to the technical field of aerospace component processing. Background Art

[0002] The slotted bushing is a commonly used component for fatigue strengthening of installation holes on airplanes, mainly processed by cold extrusion strengthening technology. It has the characteristics of large interference, strong operability, and obvious extrusion effect, and can significantly improve the fatigue life of various material structural parts. With the advancement of the localization of slotted bushings, domestic slotted bushings are increasingly widely used and have achieved good usage effects.

[0003] One end of the slotted bushing is provided with a flanging structure, which is convenient for installation and disassembly. Flanging is a key process of the slotted bushing, that is, using a mold and stamping processing to turn the hole end edge or outer edge of the cylindrical semi-finished slotted bushing into a straight edge or bevel edge facing outward. The components processed by the flanging process can have good rigidity. It is understood that at present, the flanging processing of domestic slotted bushings mainly uses a punching press and a customized mold for stamping processing. Due to the lack of a suitable automated feeding device, manual feeding is still relied on in the prior art, resulting in low processing efficiency. Summary of the Invention

[0004] Aiming at the defect in the prior art that the flanging process of the slotted bushing still relies on manual feeding and has low processing efficiency, the present invention provides a feeding device for flanging of a slotted bushing.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A feeding device for flanging of a slotted bushing includes a frame, and a pushing component and a flipping component are arranged on the frame; The pushing component includes a stop mechanism and a pushing mechanism. The stop mechanism is used to block the bushing, and the pushing mechanism is used to push the bushing blocked by the stop mechanism to the flipping component; The flipping component includes a flipping base, a flipping plate is rotatably arranged on the flipping base, and a bearing plate, a pressing mechanism and a blanking mechanism are arranged on the flipping plate. The bearing plate is used to support the bushing. The pressing mechanism includes a pressing member, and the pressing member is movably installed on the flipping plate. The pressing member is used to press the bushing supported on the bearing plate. The blanking mechanism includes a blanking plate, and the blanking plate is movably installed on the flipping plate. The blanking plate is used to push the bushing to be blanked into the mold after the flipping plate is flipped.

[0006] The beneficial effects of the present invention are as follows: The present invention realizes the blocking and feeding of the bushing through the feeding component, feeds the bushing to the flipping component, and the flipping component realizes the fixation of the bushing through the material receiving plate and the pressing mechanism, flips the bushing in place through the flipping plate, and pushes the bushing into the mold through the blanking plate, thereby realizing the automatic feeding of the bushing, eliminating the need for manual feeding and improving the processing efficiency.

[0007] Based on the above technical solutions, the present invention can also be improved as follows: Further, the flipping component further includes a lifting seat plate and a flipping power mechanism. The lifting seat plate is installed on the flipping machine base in a liftable manner. The flipping plate is installed on the lifting seat plate, and the output end of the flipping power mechanism is connected to the flipping plate.

[0008] The beneficial effects of adopting the above further technical solutions are as follows: The lifting of the lifting seat plate enables the flipping plate to rise and approach the feeding component to receive the bushing, and also enables it to descend and approach the mold to realize the blanking of the bushing; the flipping power mechanism drives the flipping of the flipping plate.

[0009] Further, the flipping plate and the flipping power mechanism are movably installed on the lifting seat plate through an adjustment component.

[0010] The beneficial effects of adopting the above further technical solutions are as follows: The flipping plate and its flipping power mechanism are installed on the lifting seat plate through the adjustment component, enabling the flipping plate to translate on the lifting seat plate. Since the central axes of bushings of different sizes have different heights on the flipping plate, when the bushing is flipped driven by the flipping plate, the position of the flipping plate before flipping will affect the position of the central axis of the bushing after flipping. Generally, the position of the central axis of the mold for flanging the bushing is fixed. When it is necessary to adapt to the flanging processing of bushings of different sizes, if the position of the flipping plate is not adjusted, after the flipping plate flips, the position of the central axis of the bushing will shift, and the relative position between the central axis of the bushing and the central axis of the mold will change, affecting the entry of the bushing into the mold. By adjusting the position of the flipping plate on the lifting seat plate through the adjustment component, the position of the central axis of the bushing after flipping can be adjusted, thereby ensuring the alignment of the central axis of the bushing and the central axis of the mold and improving the accuracy during the process of feeding the bushing into the mold.

[0011] Further, the adjustment component includes a translation seat. The translation seat is movably installed on the lifting seat plate. The flipping plate is rotatably installed on the translation seat. One end of the translation seat is connected with a translation driving mechanism. An installation plate is provided on the lifting seat plate. The translation driving mechanism is installed on the installation plate, and a locking buckle is provided on the installation plate.

[0012] The beneficial effects of adopting the above further technical solution are as follows: The translation seat is driven to move on the lifting seat plate by the translation driving mechanism, thereby driving the flipping plate to move, and the adjusted translation seat is locked by the locking buckle.

[0013] Further, the flipping power mechanism includes a flipping cylinder, a transmission rack and a transmission gear. The flipping cylinder is installed on the translation seat. The transmission rack is movably installed on the translation seat. The end of the piston rod of the flipping cylinder is connected to the transmission rack. The transmission gear is rotatably installed on the translation seat through a bearing. The transmission gear meshes with the transmission rack, and the transmission gear is fixedly connected to the flipping plate.

[0014] The beneficial effects of adopting the above further technical solution are as follows: The telescopic movement of the piston rod of the flipping cylinder drives the transmission rack to move on the lifting seat plate. The movement of the transmission rack can drive the transmission gear to rotate, thereby driving the flipping plate to rotate and realizing the flipping of the flipping plate. Since the material bearing plate is arranged on the flipping plate, when the bushing is placed on the material bearing plate, the bushing is horizontally placed. The pressing member moves downward to press the bushing. When the flipping plate flips, the bushing horizontally placed on the material bearing plate can be driven to flip to a vertical state, which is convenient for feeding the bushing into the mold. During this process, the pressing member keeps pressing the bushing to prevent the bushing from falling off in advance.

[0015] Further, the pressing member includes a pressing plate. There is a slot in the middle of the pressing plate, and the blanking plate is arranged corresponding to the slot of the pressing plate.

[0016] The beneficial effects of adopting the above further technical solution are as follows: Since the bushing is horizontally placed on the material bearing plate, when the pressing plate presses the bushing, the cylindrical surface of the bushing contacts the pressing plate. If single-sided contact is adopted, it is easy for the bushing to roll over. There is a slot on the pressing plate, so that the contact surface between the pressing plate and the bushing increases to two, which can better press the bushing, prevent the bushing from shifting or rolling, and can adapt to bushings of different diameters without adjusting the structure of the pressing plate according to the size of the bushing. In addition, the slot can also provide a moving channel for the blanking plate.

[0017] Further, the pushing mechanism includes a pushing frame and a pushing power cylinder. The pushing power cylinder is fixedly installed on the machine frame. The pushing frame is movably installed on the machine frame. The piston rod of the pushing power cylinder is connected to the pushing frame, and the material blocking mechanism is arranged on the pushing frame.

[0018] The beneficial effects of adopting the above further technical solution are as follows: The pushing frame is driven to move by the pushing power cylinder, thereby driving the material blocking mechanism to move, and the material blocking mechanism drives the bushing to move.

[0019] Further, the material blocking mechanism includes a material blocking member and a material blocking power cylinder. The material blocking power cylinder is fixedly installed on the material pushing frame. The material blocking member is installed at the end of the piston rod of the material blocking power cylinder. A space for accommodating a bushing is provided between the material blocking member and the material pushing frame.

[0020] The beneficial effect of adopting the above further technical solution is that the bushing is blocked by the material blocking member. A space for accommodating the bushing is provided between the material blocking member and the material pushing frame. When the material blocking member moves driven by the material pushing power cylinder and the material pushing frame, the bushing can be driven to move.

[0021] Further, the material blocking member includes a material blocking top plate and a material blocking side plate. The piston rod of the material blocking power cylinder is connected to the material blocking top plate. The material blocking side plate is arranged at the end of the material blocking top plate.

[0022] The beneficial effect of adopting the above further technical solution is that the end of the bushing is blocked and positioned by the material blocking top plate, and the side of the bushing is blocked by the material blocking side plate, so as to prevent the bushing from shifting during the movement.

[0023] Further, the material pushing frame includes a moving frame body and a material blocking push plate. The piston rod of the material pushing power cylinder is connected to the moving frame body. The material blocking push plate is arranged at the end of the moving frame body. A material guiding support plate is provided at the bottom of the moving path of the material blocking push plate.

[0024] The beneficial effect of adopting the above further technical solution is that the bushing moves on the material guiding support plate, and the side of the bushing is blocked by the material blocking side plate and the material blocking push plate, so as to prevent the bushing from shifting during the movement.

Detailed implementation manners

[0027] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0028] See Figures 1-6 , a feeding device for flanging a slotted bushing, including a frame (not shown in the figure), wherein a material pushing assembly 200 and a flipping assembly 300 are provided on the frame; The material pushing assembly 200 includes a material blocking mechanism and a material pushing mechanism. The material blocking mechanism is used to block the bushing so that there is only a gap for one bushing product at the position to be pushed. The material pushing mechanism is used to push the bushing blocked by the material blocking mechanism to the flipping assembly 300; The flipping assembly 300 includes a flipping base 301. A liftable lifting seat plate 312 is provided on the flipping base 301. A lifting power cylinder 313 is provided on the flipping base 301. The end of the piston rod of the lifting power cylinder 313 is connected to the lifting seat plate 312.

[0029] A turnover plate 308 is provided on the lifting seat plate 312. A material supporting plate 302, a material pressing mechanism and a blanking mechanism are provided on the turnover plate 308. The material supporting plate 302 is used for supporting the bushing. In order to better support the bushing and facilitate the bushing to roll into place, the middle of the upper surface of the material supporting plate 302 is low and both sides are high, so that the upper surface of the material supporting plate 302 is integrally V-shaped. When the feeding assembly pushes the bushing product to the material supporting plate 302, due to the cylindrical shape of the bushing, the V-shaped structure of the upper surface of the material supporting plate 302 can facilitate the bushing to roll down to the concave part of the upper surface of the material supporting plate 302, which is easy to position the bushing and can prevent the bushing from moving. Cooperating with the material pressing mechanism, bushings with different diameters can be locked and accurately positioned, so as to accurately feed the bushing into the mold; the material pressing mechanism includes a material pressing part, and the material pressing part is movably installed on the turnover plate 308. The material pressing part is used for pressing the bushing supported on the material supporting plate 302 before the turnover plate 308 turns or while the turnover plate 308 turns. The blanking mechanism includes a blanking plate 303, and the blanking plate 303 is movably installed on the turnover plate 308. The blanking plate 303 is used for pushing the bushing to be blanked into the mold after the turnover plate 308 turns.

[0030] The turnover assembly 300 further includes a turnover power mechanism, and the output end of the turnover power mechanism is connected to the turnover plate 308. In order to adapt to bushings of different sizes, the turnover plate 308 and the turnover power mechanism are movably installed on the lifting seat plate 312 through an adjustment assembly. The moving direction of the turnover plate 308 on the lifting seat plate 312 is perpendicular to the lifting direction of the lifting seat plate 312.

[0031] Specifically, the adjustment assembly includes a translation seat 401. The translation seat 401 is movably installed on the lifting seat plate 312 through a guide rail 402 and a slider. The turnover plate 308 is rotatably installed on the translation seat 401. A translation driving mechanism is connected to the end of the translation seat 401. An installation plate 403 is provided on the lifting seat plate 312, and the translation driving mechanism is installed on the installation plate 403. The present invention does not limit the translation driving mechanism. As a preferred embodiment of the present invention, the translation driving mechanism is a handwheel 404, and the driving rod of the handwheel 404 is connected to the translation seat 401; a locking buckle 405 is provided on the installation plate 403.

[0032] Specifically, in this embodiment, the flipping power mechanism includes a flipping cylinder 305, a transmission rack 306, and a transmission gear 307. The flipping cylinder 305 is installed on the translation base 401. The transmission rack 306 is movably installed on the translation base 401. The end of the piston rod of the flipping cylinder 305 is connected to the transmission rack 306. The transmission gear 307 is rotatably installed on the translation base 401 through a bearing. The transmission gear 307 meshes with the transmission rack 306, and the transmission gear 307 is fixedly connected to the flipping plate 308. The telescopic movement of the piston rod of the flipping cylinder 305 drives the transmission rack 306 to move on the translation base 401. Since the transmission rack 306 meshes with the transmission gear 307, the movement of the transmission rack 306 can drive the transmission gear 307 to rotate, thereby driving the flipping plate 308 to rotate and realizing the flipping of the flipping plate 308. Since the material receiving plate 302 is arranged on the flipping plate 308, when the pushing component 200 pushes the bushing onto the material receiving plate 302, the bushing is horizontally placed. The pressing component moves downward to press the bushing. When the flipping plate 308 flips and drives the material receiving plate 302 to rotate, the bushing horizontally placed on the material receiving plate 302 is driven to flip to a vertical placement. During this process, the pressing component keeps pressing the bushing to prevent the bushing from falling off in advance.

[0033] The pressing mechanism includes a pressing power cylinder 309. The pressing power cylinder 309 is installed on the flipping plate 308. The end of the piston rod of the pressing power cylinder 309 is connected to the pressing component. The pressing component includes a connecting block 310 and a pressing plate 304. A connecting plate is provided at the end of the piston rod of the pressing power cylinder 309. The connecting block 310 is installed on the connecting plate. The pressing plate 304 is installed on the connecting block 310. A slot is provided in the middle of the pressing plate 304, and the blanking plate 303 is arranged corresponding to the slot of the pressing plate 304. Since the bushing is horizontally placed on the material receiving plate 302, when the pressing plate 304 presses the bushing, it is the cylindrical surface of the bushing that contacts the pressing plate 304. If single-sided contact is used, it is easy for the bushing to roll over. By providing a slot in the pressing plate 304, the contact surface between the pressing plate 304 and the bushing is increased to two, so that the bushing can be better pressed to prevent the bushing from shifting or rolling, and the slot provides a movement channel for the blanking plate 303.

[0034] The blanking mechanism includes a blanking power cylinder 311. The blanking power cylinder 311 is installed on the flipping plate 308. The end of the piston rod of the blanking power cylinder 311 is connected to the blanking plate 303.

[0035] The material pushing mechanism includes a material pushing frame 201 and a material pushing power cylinder 202. The material pushing power cylinder 202 is fixedly installed on the machine frame. The material pushing frame 201 is movably installed on the machine frame. The piston rod of the material pushing power cylinder 202 is connected to the material pushing frame 201. The material blocking mechanism is arranged on the material pushing frame 201.

[0036] The material blocking mechanism includes a material blocking member and a material blocking power cylinder 205. The material blocking power cylinder 205 is fixedly installed on the material pushing frame 201. The material blocking member is installed at the end of the piston rod of the material blocking power cylinder 205. A space for accommodating a bushing is provided between the material blocking member and the material pushing frame 201.

[0037] The material blocking member includes a material blocking top plate 203 and a material blocking side plate 204. The piston rod of the material blocking power cylinder 205 is connected to the material blocking top plate 203. The material blocking side plate 204 is arranged at the end of the material blocking top plate 203. The material blocking member is a quick-change part. By using material blocking members of different sizes to match bushing products of different lengths, the present invention is adapted to the flanging processing of bushing products of different sizes.

[0038] The material pushing frame 201 includes a moving frame body 2011 and a material blocking push plate 2012. The piston rod of the material pushing power cylinder 202 is connected to the moving frame body 2011. The material blocking push plate 2012 is arranged at the end of the moving frame body 2011. A gap is left between the material blocking side plate 204 and the material blocking push plate 2012, that is, a space for accommodating a bushing is formed among the material blocking side plate 204, the material blocking top plate 203 and the material blocking push plate 2012. A material guiding support plate is provided at the bottom of the moving path of the material blocking push plate 2012. The side of the material guiding support plate facing the flipping assembly 300 is inclined downward. The height of the material receiving plate 302 is lower than that of the material guiding support plate. In this embodiment, both the material blocking member and the material blocking push plate 2012 are quick-change mechanisms. The length of the material blocking push plate 2012 is adapted to the length of the bushing. Acting together with the material blocking member, the positioning in the length direction of the bushing is realized through the material blocking push plate 2012. The material blocking member and the material blocking push plate 2012 jointly position the bushing in the width direction. The two cooperate to realize the positioning of bushing products of different lengths, and quick changeover and precise positioning can be achieved.

[0039] The operation process of the feeding device for the flanging processing of the slotted bushing of the present invention is as follows: 1. The conveyance before the bushing feeding can be realized by mechanisms such as a conveyor belt or a vibrating feeding tray. In this embodiment, the bushing is conveyed by a vibrating feeding tray. Before that, the piston rod of the material blocking power cylinder 205 extends to drive the material blocking top plate 203 and the material blocking side plates 204 to move into place. At this time, a space for accommodating the bushing is formed among the material blocking side plates 204, the material blocking top plate 203, and the material blocking push plate 2012. The vibrating feeding tray conveys the bushing to the material guiding support plate and into the space for accommodating the bushing formed among the material blocking side plates 204, the material blocking top plate 203, and the material blocking push plate 2012.

[0040] 2. The piston rod of the material pushing power cylinder 202 extends to drive the material pushing frame 201 and the material blocking assembly to move towards the flipping assembly 300. Before that, the lifting power cylinder 313 drives the lifting seat plate 312 to rise into place, so that the height of the material receiving plate 302 is adapted to the height of the material guiding support plate. The bushing is pushed by the material pushing frame 201, moves on the material guiding support plate, and rolls from the material guiding support plate onto the material receiving plate 302. The material blocking side plates 204 and the material blocking push plate 2012 provide blocking on both sides of the bushing to prevent the bushing from shifting.

[0041] 3. After the bushing moves onto the material receiving plate 302, the material blocking power cylinder 205 retracts, so that the material blocking side plates 204 do not contact the bushing and are not on the same vertical line. The material pushing power cylinder 202 retracts to drive the material blocking push plate 2012, the material blocking top plate 203, and the material blocking side plates 204 to reset, so that the bushing is independently located on the material receiving plate 302.

[0042] 4. After the bushing moves onto the material receiving plate 302, the pressing power cylinder 309 drives the pressing member to move downward, and the pressing plate 304 presses the bushing. At this time, the flipping cylinder 305 drives the transmission rack 306 to move. The movement of the transmission rack 306 drives the transmission gear 307 to rotate, and the flipping plate 308 flips along with the transmission gear 307, thereby driving the bushing on the material receiving plate 302 to flip. The angle by which the flipping cylinder 305 drives the transmission gear 307 to rotate is 90°, so that the bushing flips from the horizontal placement to the vertical placement, ensuring that the bushing can be aligned with the accommodation cavity of the mold.

[0043] 5. After the bushing flips into place, the lifting power cylinder 313 drives the lifting seat plate 312 to descend, so that the bushing approaches the mold. After the lifting seat plate 312 descends into place, the piston rod of the blanking power cylinder 311 drives the blanking plate 303 to move towards the bushing, and pushes the bushing into the mold, completing the feeding of the bushing.

[0044] 6. After the feeding of the bushing is completed, the flipping cylinder 305 drives the transmission rack 306 to move in the reverse direction. The movement of the transmission rack 306 drives the transmission gear 307 to rotate, and the flipping plate 308 flips and resets along with the transmission gear 307. The lifting power cylinder 313 drives the lifting seat plate 312 to rise, and continues to complete the feeding operation of the next bushing.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
