Detailed Implementation

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0034] First, combine Figures 1-7 This invention describes a crankshaft omnidirectional transport device according to an embodiment of the present invention, used to transport a crankshaft to an installation station.

[0035] like Figures 1-7 As shown, an embodiment of the present invention provides a crankshaft omnidirectional handling device, comprising: a robotic arm assembly 1, a clamping assembly 2, and a control assembly 3;

[0036] The robotic arm assembly 1 includes: a support column 11, a rotating cap 12, and a connecting rod 5;

[0037] The top of the support column 11 is rotatably connected to the rotating cap 12, one end of the rotating cap 12 is connected to the connecting rod 5, and one end of the connecting rod 5 is hinged to the clamping assembly 2;

[0038] The clamping assembly 2 includes: a clamping rod 21, a changing cylinder 22, a changing plate 23, and a clamping mechanism 4;

[0039] One end of the clamping rod 21 is hinged to the connecting rod 5, one end of the changing cylinder 22 is fixed on the clamping rod 21, the output end of the changing cylinder 22 is rotatably connected to the first end of the changing plate 23, the second end of the changing plate 23 is connected to the clamping mechanism 4, the changing plate 23 is rotatably connected to the end of the clamping rod 21, and the clamping mechanism 4 is used to clamp the crankshaft.

[0040] The control component 3 is located on the clamping rod 21 and is used to control the clamping mechanism 4 to clamp the crankshaft.

[0041] In this application, the worker can push the clamping assembly 2 to move by controlling the component 3, causing the rotating cap 12 to rotate on the support column 11, thereby adjusting the position of the clamping assembly 2 so that the clamping mechanism can clamp the crankshaft. By retracting the output end of the changing cylinder 22, the changing plate 23 is pulled to rotate 90° on the clamping rod 21, so that the clamping mechanism 4 can clamp the crankshaft. The output end of the changing cylinder 22 extends, so that the crankshaft on the clamping mechanism 4 is perpendicular to the ground. The worker can push the clamping assembly 2 to move by controlling the component 3, thereby realizing the handling of the crankshaft and improving the handling efficiency of the crankshaft.

[0042] like Figures 4-7 As shown, the clamping mechanism 4 includes: a clamping slide rail 41, a locking mechanism 42, a first clamping cylinder 43, a second clamping cylinder 44, and a gripper 45;

[0043] The clamping slide rail 41 is fixed to the second end of the conversion plate 23. The first clamping cylinder 43 is slidably disposed on the clamping slide rail 41. The second clamping cylinder 44 is fixed to one end of the clamping slide rail 41. The output ends of the first clamping cylinder 43 and the second clamping cylinder 44 are both connected to the gripper 45. The gripper 45 is used to grip the crankshaft. The locking mechanism 42 is disposed on the clamping slide rail 41 and is used to lock the first clamping cylinder 43 on the clamping slide rail 41.

[0044] In this embodiment, when the clamping mechanism 4 needs to grip the crankshaft, the distance between the first clamping cylinder 43 and the second clamping cylinder 44 is adjusted by sliding the first clamping cylinder 43 on the clamping slide rail 41. This ensures that the grippers 45 on the first and second clamping cylinders 43 and 44 are positioned in the same axial direction to grip the crankshaft. The first clamping cylinder 43 is then locked to the clamping slide rail 41 by the locking mechanism 42, enabling the clamping mechanism 4 to grip crankshafts of different sizes. In this embodiment, the grippers 45 are the existing grippers 45, as long as they can grip cylindrical objects.

[0045] like Figures 1-3 As shown, the robotic arm assembly 1 also includes: a hinge plate 13, an adjusting cylinder 14, and an adjusting rod 15;

[0046] The hinge plate 13 is rotatably mounted on the support column 11. One end of the adjusting cylinder 14 is hinged to the hinge plate 13. The output end of the adjusting cylinder 14 is rotatably connected to the first end of the adjusting rod 15. The second end of the adjusting rod 15 is rotatably connected to the rotating cap 12 and connected to the connecting rod 5.

[0047] In this embodiment, the adjusting cylinder 14 drives the adjusting rod 15 to rotate, which in turn drives the connecting rod 5 to rotate, thereby adjusting the height of the clamping mechanism 4 so that the clamping mechanism 4 can clamp the crankshaft.

[0048] like Figures 1-4 As shown, the connecting rod 5 includes: a first connecting rod 51, a transition plate 52, a rotating disk 53, and a second connecting rod 54;

[0049] One end of the first connecting rod 51 is connected to the second end of the adjusting rod 15, and the other end is rotatably connected to the first end of the transition plate 52. The bottom of the second end of the transition plate 52 is provided with a rotating disk 53. The bottom of the rotating disk 53 is connected to the first end of the second connecting rod 54, and the second end of the second connecting rod 54 is hinged to the clamping assembly 2. The transition plate 52 is set parallel to the ground.

[0050] In this embodiment, when the adjusting cylinder 14 drives the first connecting rod 51 to rotate, the transition plate 52 always remains horizontal, so that the clamping mechanism 4 can move vertically, ensuring that the clamping mechanism 4 can clamp the crankshaft. By setting a rotating disk 53 between the transition plate 52 and the second connecting rod 54, the flexibility of the worker in moving the clamping mechanism 4 is improved.

[0051] like Figures 1-3 As shown, the robotic arm assembly 1 also includes: a limiting plate 16, a limiting block, and a limiting rod 17;

[0052] One end of the limiting plate 16 is fixed to the rotating cap 12, and the other end is rotatably connected to the limiting block. The limiting rod 17 passes through the limiting block and slides on the limiting block. One end of the limiting rod 17 is hinged to the connecting rod 5. Two limiting sleeves are provided on the limiting rod 17, and the limiting block is located between the two limiting sleeves.

[0053] In this embodiment, when the regulating cylinder 14 drives the first connecting rod 51 to rotate, the limiting block slides on the limiting rod 17. By setting two limiting sleeves on the limiting rod 17, the range of sliding of the limiting block on the limiting rod 17 is limited, thereby limiting the vertical movement range of the clamping mechanism 4.

[0054] like Figures 2-7 As shown, the clamping assembly 2 further includes: a hinge 24, a rotary joint 25, a brake cylinder 26, and an air vent box 27;

[0055] The hinge 24 is hinged to the connecting rod 5. One end of the rotating joint 25 is connected to the hinge 24, and the other end is connected to the clamping rod 21. The brake cylinder 26 is fixed on the clamping rod 21, and the output end of the brake cylinder 26 faces the rotating joint 25. The air box 27 is located on the clamping rod 21. The air box 27 is equipped with a pressure gauge, an indicator light, and a pressure adjustment knob.

[0056] In this embodiment, the clamping rod 21 can be rotated by the rotary joint 25, thereby adjusting the angle of the clamping mechanism 4 so that the clamping mechanism 4 can clamp the crankshaft. The rotary joint 25 can be locked by the brake cylinder 26 so that the rotary joint 25 cannot be rotated.

[0057] like Figures 5-7 As shown, the control component 3 includes: a first lever 31, a second lever 32, and a control button 33;

[0058] The first lever 31 and the second lever 32 are respectively located on both sides of the clamping rod 21. The first lever 31 and the second lever 32 are arranged in parallel. Both the first lever 31 and the second lever 32 are equipped with control buttons 33.

[0059] In this embodiment, after the worker grasps the first lever 31 and the second lever 32, the worker can move the clamping mechanism 4 by pushing the first lever 31 and the second lever 32, and can move the clamping mechanism 4 to the position of the crankshaft to be clamped. The control button 33 can control the clamping and releasing of the crankshaft, and can also control the switching of the brake cylinder 26, the adjusting cylinder 14 and the changing cylinder 22.

[0060] Above, refer to Figures 1-7 This invention describes a crankshaft omnidirectional handling device according to an embodiment of the present invention. The worker can move the clamping assembly 2 by controlling the component 3, causing the rotating cap 12 to rotate on the support column 11, thereby adjusting the position of the clamping assembly 2 so that the clamping mechanism can grip the crankshaft. By retracting the output end of the changing cylinder 22, the changing plate 23 is pulled to rotate 90° on the clamping rod 21, enabling the clamping mechanism 4 to grip the crankshaft. The output end of the changing cylinder 22 extends, making the crankshaft on the clamping mechanism 4 perpendicular to the ground. The worker can move the clamping assembly 2 by controlling the component 3 to achieve crankshaft handling and improve crankshaft handling efficiency.
