Description

Technical Field

[0001] This application relates to the field of oil slingers, and in particular to an oil slinger for crankshaft machining. Background Technology

[0002] With the rapid development of the automotive industry, the performance and quality requirements of engines, as core components of automobiles, are increasingly stringent. Crankshafts, as a crucial part of the engine, are directly affected by their machining quality, impacting the overall performance and lifespan of the engine. Polishing is a critical process in crankshaft machining, aiming to improve the surface smoothness and roughness to meet the demands of high-precision operation. However, a large amount of auxiliary grinding oil is required during crankshaft polishing. This oil often remains on the crankshaft surface after polishing. If not removed promptly, it not only affects the subsequent assembly and performance of the crankshaft but also contaminates downstream processing equipment, increasing maintenance costs. Oil-slinging machines utilize centrifugal force to remove residual grinding oil from the crankshaft surface through high-speed rotation, achieving thorough cleaning. This physical cleaning method is more efficient and thorough than traditional manual wiping or simple cleaning equipment, ensuring complete removal of oil stains from the crankshaft surface.

[0003] A search revealed Chinese Patent Publication No. CN210550478U, which discloses a crankshaft oil slinger, comprising a frame, a crankshaft lifting device, a power head device, a driven shaft device, an oil recovery device, and a controller. The crankshaft lifting device, power head device, driven shaft device, oil recovery device, and controller are all mounted on the frame. A first opening and a push-pull plate are located above the frame. The oil recovery device includes an upper oil mist recovery device and a lower oil recovery device. The crankshaft lifting device is located directly below the first opening and includes a lifting assembly, a rotating assembly, and an oil slinger station. The lifting assembly is connected to the rotating assembly, and the oil slinger station is located on the rotating assembly. This invention is suitable for automatic oil slinging processing of crankshafts from various engine types. It features a stable tilting structure, high processing efficiency, a small equipment size, the ability to change the workpiece's posture, effective recovery of grinding oil, and avoidance of pollution to downstream equipment, resulting in a high degree of automation.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses an oil slinger for crankshaft machining.

[0029] like Figure 1-5As shown, an oil slinger for crankshaft processing includes an oil slinger 1 and a slide plate 14. The oil slinger 1 is equipped with a rotating mechanism, which includes a circular slide 100, a sliding block 3, a support rod 4, and a horizontal motor 6. The circular slide 100 is rotatably connected to the sliding block 3, the sliding block 3 is fixedly connected to the support rod 4, and the rotating end of the horizontal motor 6 is fixedly connected to a "C"-shaped frame 5.

[0030] The slide plate 14 is provided with a limiting mechanism, which includes a crankshaft positioning frame 11, an "L"-shaped frame 12 and a slider 13. The slider 13 is slidably connected to the slide plate 14, and the "L"-shaped frame 12 is fixedly connected to the slider 13. One end of the "L"-shaped frame 12 is fixedly connected to the crankshaft positioning frame 11.

[0031] Please see Figure 1 The bottom of the oil slinger 1 has a through slot, and the bottom of the oil slinger 1 is fixedly connected to the oil recovery tank 2. Both the oil slinger 1 and the oil recovery tank 2 are existing technologies, and their specific working principles, internal structures and positional relationships will not be elaborated here.

[0032] Please see Figure 2 The oil slinger 1 has a circular groove 100. A motor base 7 is fixedly connected to the inner wall of the oil slinger 1 and to the middle of the circular groove 100. A horizontal motor 6 is fixedly connected to the motor base 7. The horizontal motor 6 is connected to an external power source. The rotation of the horizontal motor 6 drives the "C"-shaped frame 5 to rotate. The rotation of the "C"-shaped frame 5 drives the support rod 4 and the sliding block 3 to rotate. At the same time, the sliding block 3 rotates in the circular groove 100.

[0033] Please see Figure 3 The top of the "C"-shaped frame 5 has a through groove 50, and the "C"-shaped frame 5 has a through hole 51 that passes through the through groove 50. A bolt 20 is inserted into the through hole 51, and the thread of the bolt 20 passes through the lifting block 19. A handle 190 is fixedly connected to the top of the lifting block 19. The lifting block 19 is inserted into the through groove 50, and a bearing 18 is rotatably connected to the lifting block 19. A fixing rod 17 is fixedly connected to the inner ring of the bearing 18, and a fixing rod 17 is fixedly connected to the bottom surface of the fixing rod 17. The upper positioning plate 16 has a sliding groove plate 14 fixedly connected to its outer circumference. The lifting block 19 can slide up and down in the through groove 50. The lifting block 19 drives the bearing 18, the fixing rod 17, the upper positioning plate 16, the nut 15, the sliding groove plate 14, the slider 13, the "L"-shaped frame 12 and the crankshaft positioning frame 11 to move upward, so that the upper positioning plate 16 does not limit the crankshaft 10. The bolt 20 can position the lifting block 19. The handle 190 can lift the lifting block 19 and move it up and down in the through groove 50.

[0034] Please see Figure 1Nuts 15 are threaded onto the slide plate 14 and the slider 13. The inner ring of the upper positioning plate 16 is inserted into the crankshaft 10. The crankshaft positioning bracket 11 is engaged with the top of the crankshaft 10. By unscrewing the nut 15 from the slide plate 14 and the slider 13, the restriction of the nut 15 on the slider 13 can be released. At this time, the slider 13, the "L"-shaped bracket 12 and the crankshaft positioning bracket 11 can slide in the slide plate 14, and at the same time, the crankshaft positioning bracket 11 disengages from the crankshaft 10.

[0035] Please see Figure 3 The bottom of the "C"-shaped frame 5 is provided with a motor placement hole 52. The bottom surface of the vertical motor 8 is fixedly connected to the motor placement hole 52. The rotating end of the vertical motor 8 is fixedly connected to a lower positioning plate 9. The crankshaft 10 is inserted into the lower positioning plate 9. The lower positioning plate 9 and the upper positioning plate 16 together limit the vertical position of the crankshaft 10.

[0036] Please see Figure 3 The bottom of the "C"-shaped frame 5 is equipped with an energy storage module, which is electrically connected to the vertical motor 8. The energy storage module is not shown in the attached drawings of the specification. The function of the energy storage module is to supply power to the vertical motor 8.

[0037] The implementation principle of an oil slinger for crankshaft machining according to an embodiment of this application is as follows:

[0038] The horizontal motor 6 and the vertical motor 8 are turned on simultaneously. The vertical motor 8 drives the lower positioning plate 9 to rotate, the lower positioning plate 9 drives the crankshaft 10 to rotate, and the vertical motor 8 drives the "C" frame 5 and the crankshaft 10 to rotate counterclockwise in the vertical direction. This achieves the advantage that the crankshaft 10 runs along different rotation trajectories, allowing the oil to be quickly thrown out.

[0039] The support rod 4 rotates with the rotation of the "C"-shaped frame 5, and the sliding block 3 rotates in the circular groove 100, thereby assisting the horizontal motor 6 in driving the structure on the "C"-shaped frame 5 to rotate.

[0040] After the crankshaft 10 is placed between the fixed rod 17 and the lower positioning plate 9, simply unscrew the nut 15 from the slide plate 14 and slide the slider 13 to move it toward the crankshaft 10. When the crankshaft positioning bracket 11 is engaged with the top end of the crankshaft positioning bracket 11, screw the nut 15 into the slide plate 14 and the slider 13 in sequence to limit the crankshaft positioning bracket 11. At the same time, the crankshaft positioning bracket 11 can engage with the crankshaft 10 to prevent the crankshaft 10 from shaking due to rotation.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
