[0002] As engines evolve towards higher strength, lighter weight, and longer lifespan, the overall performance requirements for crankshafts are constantly increasing, placing higher demands on cooling technology. An ideal cooling system should improve cooling efficiency while ensuring cooling uniformity, and simultaneously prevent excessive distortion, cracking, and residual stress in the crankshaft during cooling. This necessitates continuous innovation in the structural design and manufacturing processes of cooling devices. In current crankshaft machining, the crankshaft is usually clamped from both ends by a clamping structure. The crankshaft is driven to rotate by the rotation of the clamping components, while the corresponding parts of the crankshaft are machined by cutting equipment and cooled by water spray at the same time. However, the existing crankshaft machining and cooling structures do not have an active vibration damping structure during the clamping and rotation of the crankshaft. When abnormal vibrations are caused by cutting force or rotational imbalance, the surface roughness and shape accuracy of the crankshaft are not ideal, which will shorten the cutting tool life.

An annular guide rail 57 is fixedly connected to the outer surface of one end of the fixed ring 56. A slider 58 is slidably connected to the outer surface of the annular guide rail 57. A rotating... The rotating ring 59 has an inner guide wheel 510 rotatably connected to its inner side. A connecting ring 511 is fixedly connected to one side surface of the rotating ring 59. Ventilation holes 512 are provided on the outer surfaces of both the connecting ring 511 and the fixed ring 56. The sliding plate 73 is made of lightweight material and slides up and down along the guide frame 72. The tripod 76 has a triangular structure and moves the sliding plate 73 upward by pushing it.

[0021] The shock absorber 52 is rotatably connected to the fixed block 51 via a bearing. The locking pin 54 is used to position one end of the crankshaft.

[0023] In this embodiment, during use, the vibration generated during crankshaft rotation cutting can be reduced by the shock absorber 52. At the same time, the radial vibration during crankshaft rotation can be greatly reduced by the rotating ring 59, making the crankshaft rotation cutting process more stable, significantly suppressing chatter, effectively reducing surface ripples caused by vibration, helping to obtain better surface roughness and shape accuracy, and effectively extending the service life of the cutting module 8 tool part.

[0024] Example 2, as Figures 5-6As shown, based on Embodiment 1, a water-blocking structure 7 is also proposed, including a water-blocking frame 71 fixedly connected to the outer surface of the fixed column 1 near the movable column 4.

[0025] In this embodiment, during use, the crankshaft can be fixed by extending the telescopic cylinder 61. During this process, the sliding plate 73 can be moved upward to block both sides of the crankshaft mounting area, preventing the coolant from splashing when the water spray module 9 cools the crankshaft. After processing, the crankshaft can be easily removed outward without the sliding plate 73 forming a large obstruction.

[0026] Example 3, as Figures 7-8 As shown, based on Embodiment 2, a water spray module 9 is further proposed, including a water tank 91 fixedly connected to the outer surface of the robot arm 2 near the cutting module 8 via a bracket. A water pump 92 is fixedly connected inside the water tank 91 via bolts. A water guide pipe 93 is fixedly connected to the outlet end of the water pump 92. A spiral hose 94 is fixedly connected to the other end of the water guide pipe 93. An annular pipe 95 is fixedly connected to the other end of the spiral hose 94.

The water guide assembly 96 includes a fixed pipe 961 fixedly connected to the outer surface of the annular pipe 95. A sleeve pipe 962 is fixedly connected to the outer surface of the fixed pipe 961. The sleeve pipe 962 and the fixed pipe 961 are connected to the annular pipe 95. A sliding tube 963 is slidably connected between 61. A tension spring 964 is connected between the rear end of the sliding tube 963 and the inner wall of the sleeve 962. A water outlet hole 965 is opened on the end surface of the sliding tube 963. The axis of the annular tube 95 coincides with the axis of the cutting module 8. The water pump 92 is located at a low position inside the water tank 91. The spiral hose 94 is an elastic hose structure. The water guiding component 96 is set in an inclined structure. The sliding tube 963 slides along the length direction of the fixed tube 961 under the impact force of water. The elastic ends of the tension spring 964 are fixedly connected to the sliding tube 963 and the sleeve 962 respectively. The sliding tube 963, the sleeve 962 and the fixed tube 961 are all mechanical seals.

[0027] In this embodiment, during the cutting process of the crankshaft by the cutting module 8, coolant can be sprayed evenly onto the part of the crankshaft being cut, thereby efficiently dissipating heat from the cutting tool of the cutting module 8 and the machining part of the crankshaft, and thus making the temperature of the cutting tool and the crankshaft more uniform.

[0028] The present invention also includes a cooling process for crankshaft machining, the cooling process comprising the following steps: Step 1: Positioning and fixing; Step 2: Machining and cutting; Step 3: Cool and remove; Specifically, step one includes: the crankshaft is picked up by a mechanical gripper, and one end is placed horizontally on the inner side of the three-jaw chuck 10. The three-jaw chuck 10 clamps one end of the crankshaft. Then the telescopic cylinder 61 extends and pushes the movable column 4 toward the crankshaft until the chuck 54 is just inserted into the other end of the crankshaft for fixation. Step two specifically includes: using the operation of the robotic arm 2, the cutting tool of the cutting module 8 is positioned to perform cutting on the crankshaft at the location where it needs to be machined; Step 3 specifically includes: During the cutting process, the water pump 92 runs, inputting the coolant in the water tank 91 into the water guide pipe 93, and then the coolant is delivered into the spiral hose 94 through the water guide pipe 93. The coolant is then introduced into the annular pipe 95 through the spiral hose 94, and finally sprayed out through the water guide assembly 96 to the cutting tool part of the cutting module 8 to cool the machined part of the crankshaft.

[0029] In summary, the specific operating principle of this invention is as follows: During use, the crankshaft is automatically gripped by a mechanical gripper, and one end of the crankshaft is horizontally inserted into the inner side of the three-jaw chuck 10. Then, it is extended by the telescopic cylinder 61, and the movable column 4 is moved by the telescopic cylinder 61 until the chuck 54 is just inserted into the hole at one end of the crankshaft, thus completing the positioning and fixing of the crankshaft. After positioning and fixing, the drive motor drives the three-jaw chuck 10 to rotate. The rotating three-jaw chuck 10 drives the crankshaft to rotate synchronously. The rotating crankshaft is then cut by the cutting module 8 at one end of the robot arm 2. When the crankshaft vibrates significantly, the moving structure 6 extends continuously, thereby squeezing the shock absorber 52 and making the fixed plate 53 fit more tightly with the crankshaft. At this time, the vibration generated by the crankshaft rotation is effectively reduced. At the same time, the rotating crankshaft will drive the fixed plate 53 and the shock absorber 52 to vibrate synchronously. Through the positioning of the rotating ring 59, the inner guide wheel 510 can rotate with the rotation of the fixed plate 53. The inner guide wheel 510 greatly suppresses the radial vibration generated during the crankshaft rotation, thereby maintaining the machining effect of the crankshaft. It can significantly suppress chatter, effectively reduce surface texture caused by vibration, help to obtain better surface roughness and shape accuracy, and effectively extend the service life of the cutting module 8 tool part.

[0030] During the extension of the telescopic cylinder 61, the movable column 4 can drive the fixed frame 75 and the triangular frame 76 to move together. The triangular frame 76 pushes the sliding plate 73 to move upward, thereby shielding both sides of the crankshaft and effectively reducing the splashing of coolant from the surface of the crankshaft to the outside.

[0031] During the machining of the crankshaft, coolant is supplied to the water tank 91 through the water inlet pipe 97. Simultaneously, the operation of the water pump 92 draws the coolant into the guide pipe 93, which supplies the coolant to the spiral hose 94. The spiral hose 94 then supplies the coolant to the annular pipe 95, which in turn supplies it to the fixed pipe 961. Finally, the coolant is sprayed out through the water outlet 965 onto the cutting part of the cutting module 8. By using the frequency conversion of the water pump 92, water with different pressures can be sprayed from the water outlet 965 of the sliding pipe 963, thus extending the sliding pipe 963 along the fixed pipe 961 by different distances. This allows the cutting module 8 to better cool the cutting part of the crankshaft.

[0032] It should be noted that in practical applications, the connecting ring 511 can be directly connected and fixed to the fixed ring 56, eliminating the need for the annular guide rail 57 and the first slider 58. The entire process is automatically controlled by the controller 3, depending on the specific algorithms and operating logic set by the manufacturer. The application is only permitted after debugging and re-evaluation.

[0033] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
