Description

Technical Field

[0001] The present application relates to the field of gripping devices, and in particular to a gripping device for processing automobile steering wheel steel rims. Background Art

[0002] In the manufacturing process of automotive steering wheel rims, after the steel is formed into a circular shape, it is transferred using a gripping device. Typically, this gripping device first grabs the rim and places it on top of a conveyor or transfer cart. Another gripping device then grabs the rim from the conveyor or transfer cart and transfers it to a grinding device for loading and grinding. This operation requires multiple steps: grabbing the rim, transferring it, and then grabbing it again and transferring it to the grinding device. This not only increases the number of steps in the overall processing but also reduces production efficiency to a certain extent. Summary of the Invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a gripping device for processing automobile steering wheel steel rims, which can realize an integrated gripping-transferring-polishing design, eliminating the redundant steps of gripping the steel rims, transferring the steel rims, and then gripping them again and sending them to the polishing device in the traditional process. The transfer and polishing operations are completed simultaneously in a single transfer process, which greatly shortens the processing cycle, reduces equipment investment and space occupation, and significantly improves the overall production efficiency of automobile steering wheel steel rims.

[0004] According to an embodiment of the present application, a gripping device for processing an automobile steering wheel steel rim includes: a moving frame and a gripping and grinding assembly, the upper portion of the moving frame is provided with a first linear slide rail, the moving end of the first linear slide rail is provided with a first bidirectional slide rail, the gripping and grinding assembly includes a first lifting frame, a second lifting frame, a first gripper, a rotating clamping plate, a driving roller, a second linear slide rail, a rotating lifting frame, a rotating shaft and a grinding head, a nut is provided at the bottom of the rotating shaft, the first lifting frame, the second lifting frame, the first gripper and the rotating clamping plate are symmetrically arranged, two driving rollers are provided, the upper portion of the first lifting frame is fixedly connected to the sliding end of the first bidirectional slide rail, The second lifting frame is arranged on one side of the lifting end of the first lifting frame, the first gripper is fixedly connected to the lifting end of the second lifting frame, an arc groove is provided at the bottom of the rotating clamping plate, the upper part of the rotating clamping plate is rotatably connected to the lifting end of the first lifting frame, the rotating end of the driving roller is located inside the arc groove, the driving roller is rotatably connected to the rotating clamping plate, the second linear slide is arranged on one side of the middle of the first linear slide, the upper part of the rotating lifting frame is rotatably connected to the sliding end of the second linear slide, two rotating axes are symmetrically provided, the rotating shaft is rotatably connected to the lifting end of the rotating lifting frame, and the grinding head is installed at the bottom of the rotating shaft.

[0005] According to the embodiment of the present application, a grabbing device for processing automobile steering wheel steel rims has the beneficial effect that the movable frame and the grabbing and polishing assembly can effectively solve the problem of low efficiency caused by multiple grabbing and transporting processes in the traditional processing flow during automobile steering wheel steel rim processing, and bring significant beneficial effects. By adjusting the overall position by the movable end of the movable frame and coordinating the sliding of the first linear slide rail and the first bidirectional slide rail, the positions of the first lifting frame, the second lifting frame and related grabbing and clamping components can be flexibly adjusted to achieve precise grabbing and transport of the formed steel rims. During operation, the first gripper first grabs the steel rim and lifts it, and then the rotating clamping plate cooperates with the drive roller to complete a stable clamping. At the same time, the first gripper is slightly loosened and limited to ensure that the steel rim is in a stable position during the transfer process. The key advantage is that the grinding operation can be completed simultaneously without an additional transfer process during the grabbing and transfer process. The second linear slide drives the rotary lifting frame to move, so that the symmetrically arranged grinding heads are accurately aligned with the outside of the steel rim. After the lifting end of the rotary lifting frame descends, the rotating end of the rotary clamping plate rotates to allow the grinding head to fit the steel rim, and the drive roller drives the steel rim to rotate, and cooperates with the rotation of the grinding head to achieve all-round grinding of the circumference of the steel rim. This "grabbing-transferring-grinding" integrated design eliminates the redundant steps of "grabbing the steel rim-transferring the steel rim-grabbing it again and sending it to the grinding device" in the traditional process, and completes the transfer and grinding operations simultaneously in a single transfer process, greatly shortening the processing cycle, reducing equipment investment and space occupancy, and significantly improving the overall production efficiency of automobile steering wheel steel rims.

[0033] The following describes the working process of a gripping device for processing an automobile steering wheel steel rim according to a specific embodiment of the present application with reference to the accompanying drawings; First, the mobile frame 100 drives the first lead screw 132 to rotate through the first motor 131 of the third linear slide 130, driving the first slider 133 to move, thereby adjusting the position of the entire device. The second motor 111 of the first linear slide 110 drives the second lead screw 112 to rotate, causing the second slider 113 to drive the first bidirectional slide 120 to move. The third motor 121 of the first bidirectional slide 120 drives the first bidirectional threaded rod 122 to rotate, allowing the third slider 123 to drive the first lifting frame 210 to move, thereby achieving precise adjustment of the grabbing position. Secondly, in the grabbing stage, the first telescopic member 213 of the first lifting frame 210 is extended and retracted, driving the second frame 212 to rise and fall, and the second telescopic member 223 of the second lifting frame 220 is extended and retracted, so that the fourth frame 222 drives the first gripper 230 to rise and fall, and the first gripper 230 grabs the steel ring.

[0044] In some OEM factories, their business often only involves a certain process in the automobile steering wheel production process, such as only being responsible for the forming processing of the steel rim, but not the subsequent grinding process. In this case, the grinding structure loses its use value and needs to be disassembled. Once the grinding structure is not easy to disassemble, it will become an additional burden during the operation of the gripping device, affecting the overall operation efficiency and smoothness.

[0045] According to this application, if Figure 3 and Figure 8-Figure 9 As shown, it also includes a disassembly assembly 300, which includes a base frame 310, a rotating frame 320, a third lifting frame 330, a second gripper 340, a two-way locking member 350 and an electrical connector 360.

Subsequently, the sliding end of the second bidirectional slide rail 351 drives the insertion rod 352 to move, so that the insertion rod 352 is withdrawn from the interior of the seventh frame 263, releasing the locking limit of the seventh frame 263. At the same time, the electrical connector 360 starts to operate, and the sixth telescopic member 361 and the seventh telescopic member 363 respectively drive related components to separate the plug 367 provided on the upper portion of the seventh frame 263 from the connecting sleeve 368 on the upper portion of the sliding end of the first linear slide rail 110.

[0051] The steering wheel sizes of cars of different types or models vary, which requires grinding structures of different specifications to match them. Therefore, the grinding device needs to be replaced. However, the common grinding device replacement equipment has a low degree of mechanization, which not only prolongs the time required for replacement, but also reduces the efficiency of the replacement operation.

[0052] According to this application, if Figure 10 and Figure 11 As shown, the replacement assembly 400 is also included. The replacement assembly 400 includes a plate frame 410, a third bidirectional slide rail 420, a screwing member 430, a fifth linear slide rail 440, a storage tray 450 and a nut screwing member 460. The plate frame 410 is fixedly connected to the upper part of one side of the base frame 310. The third bidirectional slide rail 420 is set in the middle of the plate frame 410, the fifth linear slide rail 440 is set on the upper part of the plate frame 410, and the storage tray 450 is fixedly connected to the upper part of the fifth linear slide rail 440. The storage tray 450 is symmetrically spaced apart with storage slots 451. The grinding head 290 is placed inside the storage slots 451. A polygonal slot matching the nut 281 is formed at the rotating end of the nut tightening member 460. The nut tightening member 460 is disposed at the bottom of the storage slots 451 and is rotatably connected to the storage tray 450. The screwing member 430 is symmetrically disposed above the sliding end of the third bidirectional slide rail 420. The screwing end of the screwing member 430 is inserted into the driving end of the nut tightening member 460. When the grinding head 290 needs to be replaced, before the grinding structure is separated from the gripping structure, the output end of the sixth motor 282 drives the shaft 283 to rotate, so that the two grinding heads 290 rotate to a position that is adapted to the angle of the storage slot 451 on the storage tray 450. After the grinding structure is separated from the gripping structure, the output end of the eighth motor 321 drives the eighth frame 322 to rotate, and the eighth frame 322 drives the third lifting frame 330 and the second gripper 340 to move above the storage tray 450. Next, the third bidirectional slide rail 420 drives the screwing member 430 at the upper portion of the sliding end to move, so that the screwing head 432 of the screwing member 430 is inserted into the gear plate 461 of the nut screwing member 460. The tenth motor 431 drives the screwing head 432 to rotate, which in turn drives the transmission shaft 462 to rotate via the gear plate 461. The bevel gear 463 at the end of the transmission shaft 462 meshes with the bevel gear 463 at the end of the polygonal sleeve 465, driving the polygonal sleeve 465 to rotate. Subsequently, the sliding end of the fifth linear guide rail 440 drives the storage tray 450 to move, transferring the empty storage slot 451 to the position directly below the rotating shaft 280. The eighth telescopic member 333 then extends and retracts, driving the tenth frame 332 downward, allowing the grinding head 290 at the bottom of the rotating shaft 280 to be inserted into the storage slot 451. Simultaneously, the nut 281 at the bottom of the rotating shaft 280 precisely fits into the polygonal sleeve 465 of the nut tightening member 460 at the bottom of the storage slot 451, thereby removing the nut 281 from the bottom of the rotating shaft 280. Afterwards, the third lifting frame 330 is lifted, so that the rotating shaft 280 is separated from the old grinding head 290. The sliding end of the fifth linear slide 440 drives the storage plate 450 to move again, and transfers the storage slot 451 with the new specification grinding head 290 to the bottom of the rotating shaft 280. The third lifting frame 330 descends, so that the rotating shaft 280 is inserted into the new grinding head 290. The screwing member 430 moves again, and drives the nut 281 to rotate in the opposite direction by tightening the nut member 460, fastening it to the bottom of the rotating shaft 280, completing the installation of the new grinding head 290.
