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 components in 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, anti-rust oil is applied by immersion method. First, completely immerse the crankshaft in a container of anti-rust oil to allow the anti-rust oil to evenly adhere to the surface of the crankshaft. After a certain period of time, take it out and drain the excess anti-rust oil.

[0004] During the soaking process, the crankshaft can be shaken to allow the rust-proof oil to better penetrate into various parts of the crankshaft, especially some gaps, holes and other locations, to ensure that the rust-proof 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 rust-proof oil can flow down from the workpiece surface faster, reducing the oil draining time and improving work efficiency. The existing soaking method is to directly suspend the crankshaft into the 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

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 9 The figure shows an oiling device for the crankshaft of an engine accessory, comprising a moving frame 1, with docking frames 2 fixed on both sides of the moving frame 1, a screw rod 3 and a slide rod 4 rotatably mounted on the docking frame 2, two motors 5 are fixed on the docking frame 2 through a motor frame, and the output ends of the two motors 5 are fixed to the outer ends of the screw rod 3 and the slide rod 4 respectively through a coupling; and a lifting seat 6 threadedly sleeved on the outside of the screw rod 3, the lifting seat 6 is slidably sleeved with the slide rod 4, a mounting plate 7 is rotatably mounted on the lifting seat 6, and a traction part 8 for docking the outer end of the crankshaft is installed on the outer side of the mounting plate 7; and an adjusting part 9 installed at the bottom of the docking frame 2, which drives the mounting plate 7 to rotate through the adjusting part 9, and a displacing part 10 is installed on the top of the docking frame 2, and a mounting groove 11 is opened on the outer side of the mounting plate 7, and a pushing part 12 adapted to the displacing part 10 is installed in the mounting groove 11, and the pushing part 12 is driven by the displacing part 10 to dock with the traction part 8;

[0033] In this solution, the motor 5 drives the screw 3 to rotate, thereby driving the lifting seat 6 to perform corresponding lifting and lowering movements, and correspondingly driving the traction part 8 and the crankshaft to lift and lower, so as to meet the requirements of placing the crankshaft in the container for oil immersion and subsequently pulling it up for draining.

[0034] During oil immersion, the motor 5 drives the slide bar 4 to rotate, so that the adjustment part 9 drives the mounting plate 7 to rotate, causing the crankshaft immersed in oil to shake accordingly, 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;

[0035] When draining, the pushing part 12 is driven to rotate accordingly by the spreading 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 down from the workpiece surface faster, reduce the oil draining time, and improve work efficiency.

[0036] 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.

[0037] For further information, see Figure 5 The traction part 8 includes two arc-shaped frames 13 and two traction belts 14. The two arc-shaped 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-shaped frames 13. The outer ends of the two traction belts 14 are sleeved with mounting posts 15. Several mounting posts 15 are fixed to the arc-shaped frames 13 and the outer side of the mounting plate 7. The outer ends of the mounting posts 15 are threaded with tightening caps 16.

[0038] When installing the crankshaft, the personnel first put the two arc-shaped 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. Afterwards, the crankshaft is shaken and vibrated by rotating and retracting the traction belt 14.

[0039] It should be noted that the two traction belts 14 are of the same length and are made of glass fiber, so as to be immersed in anti-rust oil without being corroded by the oil.

[0040] 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. An engaging 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. An engaging gear 21 meshing with the engaging tooth row 19 is fixed to the outer side of the bottom of the slide rod 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.

[0041] In this solution, the principle of shaking the crankshaft when it is immersed in oil is as follows:

[0042] First, the personnel install the crankshaft accordingly, then move the crankshaft to the top of the container through the moving frame 1, and then use the motor 5 to drive the screw 3 to rotate, so that the lifting base 6 is synchronously lowered, thereby driving the crankshaft to be immersed in the container to achieve the immersion operation with the anti-rust oil;

[0043] 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 slide rod 4 is driven to rotate by the motor 5, thereby realizing the rotation of the driving 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, thereby causing the adjusting tooth row 20 to drive the arc-shaped tooth plate 22 to move back and forth, causing the mounting plate 7 to rotate back and forth, thereby enabling the traction belt 14 to drive the two arc frames 13 to shake accordingly, causing the crankshaft to shake 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.

[0044] 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.

[0045] For further information, see Figure 8 - Figure 10 The pushing portion 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 covered with adjusting tooth plates 25 that mesh with the outer sides of the adjusting gears 23. 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.

[0046] Among them, the pushing part 12 includes two arc-shaped push plates 28 rotatably installed in the mounting groove 11, a push rod 29 is fixed to one end of the arc-shaped push plate 28 close to the traction belt 14, and a support plate 30 is fixed to the other end. 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. The cross-sectional shape of the mounting groove 11 is convex, so that the arc-shaped push plate 28 can slide stably along the mounting groove 11.

[0047] In this solution, the principle of crankshaft vibration when draining is:

[0048] 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 down, and the lifting seat 6 at the other end is at a high position, such as Figure 10As shown, the two spreading plates 27 in the spreading portion 10 are located between the two abutting plates 30. Then, the motor 5 drives the slide bar 4 to rotate, so that the adjusting gear 23 drives the two adjusting tooth plates 25 to move outward, and drives the two spreading plates 27 to spread the two abutting plates 30 outward, so that the two arc-shaped push plates 28 are opened outward along the mounting groove 11, so that the push rod 29 begins to abut against the traction belt 14, causing the traction belt 14 to bend. When the spreading plate 27 continues to move outward and finally disengages from the abutting plates 30, the arc-shaped push plate 28 is reset by the arc spring 32, and the traction belt 14 is correspondingly straightened from the bent state, thereby causing one end of the crankshaft to vibrate once.

[0049] Afterwards, the motor 5 drives the screw rod 3 to rotate, causing the lifting seat 6 to move down first, and the motor 5 drives the slide rod 4 to reverse, so that the prying plate 27 is reset. Then the lifting seat 6 rises and resets, and the next round of shaking operation of driving the crankshaft is started. The crankshaft is shaken to promote excess anti-rust oil to flow off the surface of the workpiece faster, reduce oil drainage time, and improve work efficiency.

[0050] In this solution, the specific process of lubricating the crankshaft includes the following steps:

[0051] In the first step, the personnel connect the two ends of the crankshaft to the two traction parts 8, and then use the moving frame 1 to drive the crankshaft to move above the container;

[0052] In the second step, the crankshaft is moved down into the container for immersion by moving the lifting seat 6 downward;

[0053] In the third step, the mounting plate 7 is driven to rotate by the adjusting portion 9, so that the crankshaft shakes in the container;

[0054] Step 4: The lifting seat 6 is moved upward, and then the moving frame 1 is moved to drive the crankshaft to move to the draining area;

[0055] In the fifth step, 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 to move by the spreading part 10, so that the corresponding bending of the traction belt 14 is reset, thereby driving the crankshaft to vibrate.

[0056] Example 2: Please refer to Figure 11 This embodiment further explains the first embodiment, and the difference lies in that the structure of the push-off plate 27 is optimized, so that the lifting seat 6 does not need to move up and down when the crankshaft is shaken.

[0057] Specifically, the opening plate 27 includes a mounting base 33 and a docking plate 34 fixed to the connecting frame 26. The docking plate 34 is rotatably installed in the mounting base 33 through a rotating shaft. A baffle 35 is fixed on the mounting base 33 to abut against the docking plate 34. The baffle 35 and the docking plate 34 are magnetically attracted to each other.

[0058] When the cam 35 is in the unlocked position, the latch 33 is in the unlocked position, and the latch 33 is in the unlocked position, so that the cam 33 is unlocked and the latch 33 is unlocked.
