Its main functions include supporting the weight of the vehicle, transmitting driving and braking forces, absorbing road impacts, and maintaining wheel alignment. The design and quality of the axle directly affect the vehicle's handling, comfort, and safety, making it an indispensable part of the automotive chassis system. The automotive axle edge grinding device is an automated or semi-automated device specifically designed to process burrs, flash, and irregular shapes on the edges of the axle after welding, aiming to improve the surface quality and dimensional accuracy of the axle edges.

After the grinding is completed, the automotive axle is manually flipped over and the other side of the automotive axle is ground.

[0004] Existing automotive axle edge grinding devices have the following problems: when grinding the edges of automotive axles, they can only be used with clamps for axles of specific sizes, resulting in poor flexibility. After grinding one side, the axles need to be manually flipped over, which reduces the efficiency of automotive axle edge grinding. To address this, we propose an automotive axle edge grinding device. Utility Model Content

[0022] Please see Figures 1-4 This embodiment provides a technical solution: an automotive axle edge grinding device, including a machine base 1, a grinding robotic arm 2 provided on the rear side of the upper end of the machine base 1, and a clamping mechanism 4.

[0023] Clamping mechanism 4: It includes a bracket 41, a transition platform 42, an annular groove 43, a circular plate 44, and clamping blocks 45. The upper end of the machine base 1 has symmetrical sliding grooves. Symmetrical brackets 41 are slidably connected between the two sliding grooves.

The fixing assembly 46 also includes threaded rods 463 and dial wheels 464. Threaded rods 463 are threadedly connected to the threaded holes on the outer surface of the clamping block 45 respectively. The lower ends of the threaded rods 463 are rotatably connected to the outer arc surfaces of adjacent arc-shaped fixing plates 462 respectively. Dial wheels 464 are fixedly connected to the opposite ends of the threaded rods 463 respectively. The clamping mechanism 4 also includes a drive assembly 47, which includes a worm gear 471, a worm wheel 472, and a motor 473. Worm wheels 472 are rotatably connected to the opposite ends of the circular plate 44 through a rotating column. Worm gears 471 are rotatably connected between the front and rear inner walls of the transfer platform 42 respectively. The worm gears 471 mesh with the vertically adjacent worm wheels 472 respectively. The adapter 42 is connected to the front end of a motor 473. The rear end of the output shaft of the motor 473 is fixedly connected to the front end of the longitudinally adjacent worm gear 471. The input end of the motor 473 is electrically connected to the output end of the microcontroller 3. The drive assembly 47 also includes a bidirectional lead screw 474, a guide post 475, and a right-angle motor 476. The bidirectional lead screw 474 is rotatably connected between the left and right inner walls of the sliding groove.

The guide post 475 is fixedly connected between the left and right inner walls of the front sliding groove, the left wall of the rear sliding groove and the left end of the left bracket 41, the opposite ends of the two brackets 41, and the right end of the right bracket 41 and the right wall of the rear sliding groove. Corrugated pipes are fixedly connected between the components, and each corrugated pipe is sleeved on the outside of the bidirectional lead screw 474. (The corrugated pipes protect the bidirectional lead screw 474, preventing grinding debris from entering the inside of the bidirectional lead screw 474 and affecting its precision and sealing.) The sliding holes at the front end of the bracket 41 are slidably connected to the guide posts 475. The right-angle motor 476 is located at the left end of the machine base 1, and the right end of the output shaft of the right-angle motor 476 is fixedly connected to the left end of the bidirectional lead screw 474. The input end of the right-angle motor 476 is electrically connected to the output end of the microcontroller 3. The clamping mechanism 4 also includes an auxiliary clamping assembly 48, which includes a telescopic rod 481, a top plate 482, and a hydraulic rod 483. The bottom wall of the machine base 1 is provided with the hydraulic rod 483.The telescopic end of the hydraulic rod 483 is fixedly connected to the top plate 482. Symmetrical telescopic rods 481 are fixedly connected between the top wall of the top plate 482 and the bottom wall of the machine base 1. When grinding the edge of the automobile axle, the automobile axle is first placed on the top of the top plate 482. Then, through the control of the microcontroller 3, the external hydraulic pump operates, sending high-pressure oil into the hydraulic rod 483 through pipelines. The telescopic end of the hydraulic rod 483 pushes the top plate 482 upwards. Guided by the telescopic rods 481, this lifts the automobile axle. Then, through the control of the microcontroller 3, the right-angle motor 476 operates. The output shaft of the right-angle motor 476 drives the bidirectional lead screw 474 to rotate. Because the rear end of the bracket 41 is connected to the double... The lead screw 474 is threaded to both ends, and its front end is slidably connected to the guide post 475. Therefore, the symmetrical brackets 41 move laterally within the sliding groove, adjusting the horizontal position of the clamping block 45. This allows the clamping block 45 to laterally clamp both ends of the vehicle axle, accommodating axles of different sizes. Next, rotating the dial wheel 464 rotates the threaded rod 463, which in turn drives the arc-shaped fixing plate 462 to move along the guide rod 461 towards the center, clamping the outer side of the axle. Then, controlled by the microcontroller 3, the external hydraulic pump operates, drawing high-pressure oil from the hydraulic rod 483 through pipelines. The telescopic end of the hydraulic rod 483 retracts, thereby moving the top plate... 482 moves downwards, then the microcontroller 3 is controlled, and the grinding robot arm 2 operates. The grinding robot arm 2 will grind the edge of the car axle. (The grinding robot arm 2 is existing technology. The grinding robot arm 2 is composed of multiple articulated arms. Each articulation point is driven by a servo motor to achieve multi-degree-of-freedom rotation. The end effector is equipped with a servo motor and a grinding head. In use, the microcontroller 3 controls the operation of the servo motors of each joint. The output shaft of the servo motor drives the rotation of each articulated arm to achieve multi-degree-of-freedom rotation. At the same time, the servo motor 2 operates. The output shaft of the servo motor 2 drives the grinding head to rotate. The robot arm will drive the grinding head to move along the edge contour of the axle according to a preset trajectory. The grinding head will grind the edge of the car axle.) (Edge grinding) After grinding, there will be an un-grinded reverse side. This will be controlled by the microcontroller 3, and the motor 473 will operate simultaneously. The output shaft of the motor 473 will drive the worm gear 471 to rotate. The rotation of the worm gear 471 will drive the circular plate 44 to rotate inside the annular groove 43 through the meshing worm wheel 472. This will then drive the car axle to rotate through the clamping block 45. Next, the grinding robot arm 2 will grind the other side of the car axle. After grinding, the telescopic end of the hydraulic rod 483 will push the top plate 482 upward to support the car axle. Then, the dial wheel 464 will be rotated to disengage the arc-shaped fixing plate 462 from the car axle. Then, the right-angle motor 476 will operate, and the output shaft of the right-angle motor 476 will rotate counterclockwise.Then, the clamping block 45 is released from its fixation to both ends of the vehicle axle via the bracket 41, adapter 42, annular groove 43, and circular plate 44. Next, the telescopic end of the hydraulic rod 483 pulls the top plate 482 downwards, allowing the polished vehicle axle to be removed.

[0024] The working principle of the automotive axle edge grinding device provided by this utility model is as follows: When grinding the edge of the automotive axle, the axle is first placed on the top of the top plate 482. Then, through the control of the microcontroller 3, the external hydraulic pump operates, and the hydraulic pump sends high-pressure oil into the hydraulic rod 483 through the pipeline. The telescopic end of the hydraulic rod 483 pushes the top plate 482 upward. Under the guidance of the telescopic rod 481, the automotive axle is lifted. Then, through the control of the microcontroller 3, the right-angle motor 476 operates, and the output shaft of the right-angle motor 476 drives the bidirectional lead screw 474 to rotate. Since the rear end of the bracket 41 is threaded to both ends of the bidirectional lead screw 474, and the front end is slidably connected to the guide post 475, the symmetrical bracket 41 will move laterally within the sliding groove to adjust the horizontal position of the clamping block 45, thereby allowing the clamping block 45 to laterally clamp the left and right ends of the vehicle axle. This accommodates axles of different sizes. Next, by rotating the dial wheel 464, the threaded rod 463 rotates. The threaded rod 463 drives the arc-shaped fixing plate 462 to move along the guide rod 461 towards the center through the threaded hole, clamping the outer side of the axle. Then, by controlling the microcontroller 3, the external hydraulic pump operates... In operation, the hydraulic pump draws high-pressure oil from inside the hydraulic rod 483 through pipelines, causing the telescopic end of the hydraulic rod 483 to retract, which in turn moves the top plate 482 downwards. Then, the microcontroller 3 controls the operation of the grinding robot arm 2, which grinds the edge of the car axle. After grinding, there will be un-grinded areas on the reverse side. The microcontroller 3 then controls the operation of the motor 473, whose output shaft drives the worm gear 471 to rotate. The rotation of the worm gear 471, through the meshing worm wheel 472, drives the circular plate 44 to rotate inside the annular groove 43, which in turn drives the clamping block 45 to rotate... The car axle rotates, and then the grinding robot arm 2 grinds the other side of the car axle. After grinding, the telescopic end of the hydraulic rod 483 pushes the top plate 482 upward to support the car axle. Then, the dial wheel 464 is rotated to disengage the arc-shaped fixing plate 462 from the car axle. Then, the right-angle motor 476 operates, and the output shaft of the right-angle motor 476 rotates counterclockwise. This causes the clamping block 45 to disengage from the fixation of both ends of the car axle through the bracket 41, the adapter 42, the annular groove 43, and the circular plate 44. Then, the telescopic end of the hydraulic rod 483 pulls the top plate 482 downward to remove the ground car axle.

[0025] It is worth noting that in the above embodiments, the grinding robotic arm 2, motor 473, and right-angle motor 476 disclosed are as follows: the grinding robotic arm 2 can be KOZA-KZH-JR6165-3100; the motor 473 can be Y132M-4; and the right-angle motor 476 can be 6IK200GU-CFTP6GU75RC. The single-chip microcontroller 3 controls the operation of the grinding robotic arm 2, motor 473, and right-angle motor 476 using methods commonly used in the prior art.
