Description

Technical Field

[0001] The invention relates to the technical field of crankshaft oiling, in particular to an oiling device for a crankshaft of an engine accessory. Background Art

[0002] The crankshaft is one of the most important parts of the engine. It is the main structure used to drive the piston to reciprocate in the cylinder. During the production, storage and transportation of the crankshaft, it may be exposed to different environmental conditions and is susceptible to corrosion and damage. Therefore, applying anti-rust oil can provide temporary protection for the crankshaft to prevent rust and other problems during these processes, ensuring that the crankshaft is in good condition before being installed in the engine.

[0003] Due to the irregular shape of the crankshaft, the anti-rust oil is applied by immersion method. First, the crankshaft is completely immersed in a container of anti-rust oil to make the anti-rust oil evenly adhere to the surface of the crankshaft. After a certain period of time, take it out and drain the excess anti-rust oil. During the soaking process, the crankshaft can be shaken to allow the anti-rust oil to better penetrate into various parts of the crankshaft, especially some gaps, holes and other locations, to ensure that the anti-rust oil is evenly covered. When draining, the crankshaft can also be properly shaken to destroy some adhesion and cohesion between the oil film and the workpiece surface, so that excess anti-rust oil can flow off the workpiece surface faster, reducing the oil draining time and improving work efficiency. The existing soaking method is to directly suspend the crankshaft into a container. During the period, there is no relevant component to shake the crankshaft, and then pull it up for draining. When draining, it is just left to drain, resulting in the oiling process taking a long time. Summary of the invention

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figure 1 - Figure 9 , an oil coating device for a crankshaft of an engine accessory shown in the figure, including a moving frame 1, docking frames 2 fixed on both sides of the moving frame 1, and further including a lead screw 3 and a slide bar 4 rotatably installed on the docking frames 2. Two motors 5 are fixed on the docking frames 2 through motor brackets. The output ends of the two motors 5 are respectively fixed to the outer ends of the lead screw 3 and the slide bar 4 through couplings; and a lifting seat 6 threadedly sleeved on the outside of the lead screw 3, the lifting seat 6 is slidably sleeved with the slide bar 4, and a mounting plate 7 is rotatably installed on the lifting seat 6. A traction part 8 for docking with the outer end of the crankshaft is installed on the outside of the mounting plate 7; and an adjusting part 9 installed at the bottom of the docking frame 2, driving the mounting plate 7 to rotate through the adjusting part 9, and a prying part 10 is installed at the top of the docking frame 2. A mounting groove 11 is opened on the outside of the mounting plate 7, and a pushing part 12 adapted to the prying part 10 is installed in the mounting groove 11, and the prying part 10 drives the pushing part 12 to dock with the traction part 8; In this solution, the motor 5 drives the lead screw 3 to rotate, so as to drive the lifting seat 6 to perform corresponding lifting and lowering movements, correspondingly driving the traction part 8 and the crankshaft to lift and lower, meeting the requirements of placing the crankshaft in a container for oil immersion operation and subsequent pulling up for draining operation; When oil immersion is carried out, the motor 5 drives the slide bar 4 to rotate, so that the adjusting part 9 drives the mounting plate 7 to rotate, causing the oil-immersed crankshaft to perform corresponding shaking, improving the contact between the crankshaft and the rust preventive oil, and enabling the rust preventive oil to better penetrate into all parts of the crankshaft; When draining, the pushing part 12 is driven to rotate accordingly by the pushing part 10, so that the traction part 8 is bent accordingly, which can drive the crankshaft to shake, promote the excess anti-rust oil to flow off the workpiece surface faster, reduce the oil drainage time, and improve work efficiency.

[0020] It should be noted that the two motors 5 on the docking frame 2 are distributed at the top and bottom of the docking frame 2. The staggered installation of the top and bottom can reasonably utilize the space.

[0021] For further information, see Figure 5 The traction part 8 includes two arc frames 13 and two traction belts 14. The two arc frames 13 are sleeved on the outside of one end of the crankshaft and fixed by bolts. The two traction belts 14 are distributed on the outside of the two arc frames 13. The outer ends of the two traction belts 14 are sleeved with mounting columns 15. Several mounting columns 15 are fixed to the arc frames 13 and the outer side of the mounting plate 7. The outer ends of the mounting columns 15 are threadedly sleeved with tightening caps 16. When installing the crankshaft, the personnel first put the two arc frames 13 on one end of the crankshaft, and then put the two traction belts 14 on the outside of the installation column 15 respectively, and screw on the tightening cap 16, and then repeat the installation on the other end of the crankshaft to complete the suspension of the crankshaft. After that, the shaking and vibrating operations of the crankshaft are realized by rotating and retracting the traction belt 14.

[0022] It should be noted that the two traction belts 14 have the same length and are made of glass fiber, so as to be immersed in anti-rust oil without being corroded by the oil.

[0023] For further information, see Figure 6 as well as Figure 7 The adjusting portion 9 includes an adjusting plate 17 and a track bar 18 fixed to the bottom of the docking frame 2. The adjusting plate 17 and the track bar 18 are slidably docked. A meshing tooth row 19 is fixed to the outer side of one end of the adjusting plate 17, and an adjusting tooth row 20 is fixed to the top of the other end. A meshing gear 21 meshing with the meshing tooth row 19 is fixed to the outer side of the bottom of the slide bar 4, and an arc-shaped tooth plate 22 meshing with the adjusting tooth row 20 is fixed to the outer side of the mounting plate 7; In this scheme, the principle of shaking the crankshaft when the crankshaft is immersed in oil is: First, the personnel install the crankshaft accordingly, then move the crankshaft to the top of the container through the moving frame 1, and then drive the screw rod 3 to rotate through the motor 5, so that the lifting seat 6 is synchronously lowered, thereby driving the crankshaft to be immersed in the container to achieve the immersion operation with the anti-rust oil; When the lifting seat 6 moves down to the arc-shaped tooth plate 22 and meshes with the adjusting tooth row 20, at this time, the sliding rod 4 is driven to rotate by the motor 5, thereby realizing the rotation of the meshing gear 21. The positive and negative rotation of the meshing gear 21 causes the meshing tooth row 19 and the adjusting plate 17 to perform corresponding reciprocating movements, so that the adjusting tooth row 20 drives the arc-shaped tooth plate 22 to reciprocate, and the mounting plate 7 to rotate reciprocatingly, so that the traction belt 14 can correspondingly drive the two arc-shaped frames 13 to shake, so that the crankshaft shakes in the anti-rust oil, thereby improving the contact between the crankshaft and the anti-rust oil so that the anti-rust oil can better penetrate into various parts of the crankshaft.

[0024] It should also be noted that in order to enable the traction belt 14 to drive the corresponding shaking of the arc frame 13 due to the rotation of the mounting plate 7, the distance between the two mounting columns 15 on the mounting plate 7 is designed to be consistent with the distance between the mounting columns 15 on the two arc frames 13, so that the shaking of the mounting plate 7 can drive the shaking of the arc frame 13 with a corresponding amplitude.

[0025] For further information, see Figure 8 - Figure 10 The pushing part 10 includes an adjusting gear 23 fixed to the top of the slide rod 4, and two track rods 24 are fixed to the bottom of the docking frame 2. The outer sides of the two track rods 24 are sleeved with adjusting tooth plates 25 meshing with the outer sides of the adjusting gears 23, and a connecting frame 26 is fixed to the outer end of one of the adjusting tooth plates 25, and a pushing plate 27 is fixed to the outer ends of the connecting frame 26 and the other adjusting tooth plate 25; Among them, the pushing part 12 includes two arc-shaped push plates 28 rotatably installed in the installation groove 11, a push rod 29 is fixed at one end of the arc-shaped push plate 28 close to the traction belt 14, and a support plate 30 is fixed at the other end, and an arc-shaped rod 31 is slidably installed between the two arc-shaped push plates 28, and an arc-shaped spring 32 is sleeved on the outside of the arc-shaped rod 31, wherein the cross-sectional shape of the installation groove 11 is convex, so that the arc-shaped push plate 28 can slide stably along the installation groove 11.

[0026] In this scheme, the principle of crankshaft shaking when draining is: First, the crankshaft is lifted out of the container by moving the lifting seat 6 upward, and then moved to the draining area, the lifting seat 6 at one end is moved downward, and the lifting seat 6 at the other end is at a high position, such as Figure 10As shown in the figure, the two pushing plates 27 in the pushing part 10 are made to be between the two abutting plates 30. Then, the motor 5 drives the sliding rod 4 to rotate, so that the adjusting gear 23 drives the two adjusting toothed plates 25 to move outwards, and drives the two pushing plates 27 to push the two abutting plates 30 outwards. As a result, the two arc-shaped pushing plates 28 are opened outwards along the installation groove 11, so that the pushing rod 29 starts to abut against the traction belt 14, causing the traction belt 14 to bend. When the pushing plate 27 continues to move outwards and finally disengages from the abutting plate 30, at this time, through the arc-shaped spring 32, the arc-shaped pushing plate 28 is reset, and the traction belt 14 is correspondingly straightened from the bent state, so that one end of the crankshaft shakes once; After that, the motor 5 drives the lead screw 3 to rotate, so that the lifting seat 6 first moves downwards. The motor 5 drives the sliding rod 4 to reverse, so that the pushing plate 27 is reset. Then the lifting seat 6 rises and resets, and starts the next round of operations to drive the crankshaft to shake. By using the crankshaft to shake, it can promote the excess anti-rust oil to flow down from the surface of the workpiece faster, reduce the oil draining time, and improve the work efficiency.

[0027] In this solution, the specific process of greasing the crankshaft includes the following steps: The first step is that the operator docks the two ends of the crankshaft with the two traction parts 8, and then drives the crankshaft to move above the container through the moving frame 1; The second step is that through the downward movement of the lifting seat 6, the crankshaft is moved downwards into the container for soaking; The third step is that the adjusting part 9 drives the mounting disc 7 to rotate, so that the crankshaft shakes in the container; The fourth step is that through the upward movement of the lifting seat 6 and then through the movement of the moving frame 1, the crankshaft is driven to move to the draining area; The fifth step is that the two lifting seats 6 move up and down respectively, so that the crankshaft is in an inclined state, and the pushing part 12 is driven by the pushing part 10, so that the corresponding bending and resetting of the traction belt 14 are realized, and the crankshaft is driven to shake.

[0028] Embodiment 2: Please refer to Figure 11 , this embodiment further explains Embodiment 1, and the difference is that the structure of the pushing plate 27 is optimized, so that when the crankshaft shakes, the lifting seat 6 does not need to move up and down.

[0029] Specifically, the pushing plate 27 includes a mounting seat 33 fixed to the connecting frame 26 and a docking plate 34. The docking plate 34 is rotatably mounted in the mounting seat 33 through a rotating shaft. A baffle plate 35 that abuts against the docking plate 34 is fixed on the mounting seat 33, and the baffle plate 35 and the docking plate 34 are magnetically attracted to each other.

[0030] The baffle plate 35 cannot be limited at this time, and the docking plate 34 rotates accordingly until it moves between the two anti-plates 30. The next time the docking plate 34 moves outward, it drives the anti-plate 30 to move again. There is no need for the lifting seat 6 to drive the corresponding lifting of the mounting plate 7 to satisfy the retreat and reset of the disengaging plate 27 to between the two anti-plates 30.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
