All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4 The present invention provides a technical solution: a gear shaft polishing device, including a base 1, and two opposing fixing plates 2 are provided on the upper side of the base 1. The two fixing plates 2 are vertically arranged and fixedly connected to the base 1.

[0025] A fixing component 3 is provided between the two fixing plates 2. A feeding component 4 is provided on the side of the fixing component 3 away from the base 1, and a discharging component 5 is provided on the side of the fixing component 3 close to the base 1. A polishing component 6 is provided on the side of the fixing component 3 along the length of the base 1.

[0026] The fixing component 3 includes two support plates 7 that can slide relative to each other. The two support plates 7 are located between the two fixing plates 2. The two support plates 7 are vertically arranged and slidably connected to the base 1.

[0027] Two sliders 8 are fixedly connected to the side of each support plate 7 near the base 1. The two sliders 8 are respectively set on both sides of the support plate 7 along the width direction. The base 1 has a groove 9 corresponding to the support block. The sliders 8 and the groove 9 cooperate with each other, so that the support plate 7 and the base 1 are slidably connected.

[0028] A hydraulic telescopic cylinder 10 is installed at each of the four corners of the two support plates 7 on opposite sides. The hydraulic telescopic cylinder 10 is horizontally set, and the fixed end of the hydraulic telescopic cylinder 10 is fixedly connected to the fixed plate 2. The output end of the hydraulic telescopic cylinder 10 is fixedly connected to the support plate 7, so that the support plate 7 can be driven to slide along the slide groove 9 by the hydraulic telescopic cylinder 10.

[0029] Two support plates 7 are rotatably connected to a chuck 11 on opposite sides. The chuck 11 is a three-jaw electric chuck 11, used to lock and fix gear shafts of different diameters.

[0030] One of the support plates 7 is fixedly connected to a drive motor 12 on the side opposite to the chuck 11. The output shaft of the drive motor 12 passes through the support plate 7 and is fixedly connected to the chuck 11, thereby driving the chuck 11 to rotate through the drive motor 12, which in turn drives the gear shaft to rotate.

[0031] The fixing plate 2 near the drive motor 12 has a rectangular opening 32 to prevent the drive motor 12 from colliding with the fixing plate 2 when the support plate 7 moves.

[0032] The feeding assembly 4 includes a rotatable connecting plate 13, which is disposed between two support plates 7. A linear motor 14 is fixedly connected to the connecting plate 13. The linear motor 14 has two output ends, and a hydraulic telescopic cylinder 15 is fixedly connected to each of the two output ends. An electric gripper 16 is fixedly connected to the output end of the hydraulic telescopic cylinder 15.

[0033] A rotating shaft 17 is fixedly connected to the center of both sides of the connecting plate 13 along its length. The rotating shaft 17 passes through the support plate 7 and is movably connected to the support plate 7. One end of the rotating shaft 17 along the axial direction is rotatably connected to the fixed plate 2. The other end of the rotating shaft 17 along the axial direction passes through the fixed plate 2 and is fixedly connected to the drive motor 18. The drive motor 18 is fixedly connected to the fixed plate 2. The drive motor 18 drives the rotating shaft 17 to rotate, which in turn drives the connecting plate 13 to rotate.

[0034] The discharge assembly 5 includes a rotatable connecting plate 2 19, which is disposed between two support plates 7. A linear motor 20 is fixedly connected to the connecting plate 2 19. The linear motor 20 has two output ends, and a hydraulic telescopic cylinder 3 21 is fixedly connected to each of the two output ends. An electric gripper 22 is fixedly connected to the output end of the hydraulic telescopic cylinder 3 21.

[0035] A rotating shaft 23 is fixedly connected to the center of both sides of the connecting plate 2 19 along its length. The rotating shaft 23 passes through the support plate 7 and is movably connected to the support plate 7. One end of the rotating shaft 23 along the axial direction is rotatably connected to the fixed plate 2. The other end of the rotating shaft 23 along the axial direction passes through the fixed plate 2 and is fixedly connected to the drive motor 3 24. The drive motor 3 24 is fixedly connected to the fixed plate 2. The drive motor 3 24 drives the rotating shaft 23 to rotate, which in turn drives the connecting plate 2 19 to rotate, thereby transporting the polished gear shaft out.

[0036] The polishing assembly 6 includes a linear motor 25, the fixed end of which is fixedly connected to the base 1. The linear motor 25 has two output ends, each of which is fixedly connected to a connecting plate 26. The connecting plate 26 is vertically arranged, and a hydraulic telescopic cylinder 27 is arranged on the side of the connecting plate 26 facing the fixed assembly 3. The fixed end of the hydraulic telescopic cylinder 27 is fixedly connected to the connecting plate 26. The output end of the hydraulic telescopic cylinder 27 is fixedly connected to a housing 28, which is a concave plate with a groove 29. A grinding wheel 30 is rotatably connected in the groove 29. A drive motor 31 is fixedly connected to the housing 28, and the output shaft of the drive motor 31 passes through the housing 28 and is fixedly connected to the grinding wheel 30. Thus, the drive motor 31 drives the grinding wheel 30 to rotate, thereby polishing the gear shaft.

[0037] In this embodiment, the second drive motor 18 is started, causing the electric gripper 16 to rotate to one side. At the same time, the output end of the second hydraulic telescopic cylinder 15 is extended, and the electric gripper 16 is controlled to clamp the gear shaft on the conveyor belt. The distance between the two output ends of the linear motor 14 is controlled according to the model of the gear shaft, so that the electric gripper 16 avoids the gear part of the gear shaft and clamps the shaft part of the gear shaft.

[0038] After the electric gripper 16 completes the gripping, the output end of the hydraulic telescopic cylinder 2 15 is retracted, and the drive motor 2 18 is started again, so that the electric gripper 16 drives the gear shaft to rotate to one side of the fixed component 3.

[0039] Control the extension and retraction of the second hydraulic telescopic cylinder 15 so that the axis of the gear shaft is aligned with the center of the chuck 11. Then control the output end of the first hydraulic telescopic cylinder 10 to extend, so that the two chucks 11 move closer to each other and clamp the end of the gear shaft.

[0040] After the chuck 11 has finished clamping the gear shaft, the electric gripper 16 is released, and then the output end of the hydraulic telescopic cylinder 15 is retracted back to its original position. The drive motor 18 is started, so that the electric gripper 16 rotates again to prepare to clamp the next gear shaft.

[0041] During the process of the feeding assembly 4 clamping the next gear shaft, the drive motor 12 is started to rotate, causing the chuck 11 to drive the gear shaft to rotate.

[0042] At the same time, drive motor 431 is started to rotate grinding wheel 30. According to the model of the gear shaft, the two output ends of linear motor 325 are controlled to move to grind and polish the two ends of the gear shaft respectively. By controlling the extension and retraction process of the output end of hydraulic telescopic cylinder 427, different step surfaces of the gear shaft are effectively ground and polished.

[0043] After grinding is completed, the operation of the polishing component 6 is stopped and reset. At the same time, the rotation of the drive motor 12 is stopped, and the two output ends of the linear motor 20 of the discharge component 5 are moved. Meanwhile, the output end of the hydraulic telescopic cylinder 21 extends, so that the electric gripper 22 clamps the shaft of the gear shaft. Then, the chuck 11 is opened and closed to stop clamping the gear shaft, and the output end of the hydraulic telescopic cylinder 10 is retracted.

[0044] Finally, start the drive motor 24 to make the electric gripper 22 hold the gear shaft and rotate it to one side, so that the gear shaft falls onto another conveyor belt. The electric gripper 22 releases, so that the gear shaft is transferred to the next process via the conveyor belt.
