Figs. 1 to 4

[0032] The oil storage chamber 1 is used for containing oil and is a circular stainless steel barrel with an open upper end and a sealed lower end. The loading basket 2 is used for loading gears and can be a cage welded by steel bars with a bottom plate welded at the bottom. The oil collecting chamber 3 is used for collecting excess oil and is a circular stainless steel barrel with an open upper end and a sealed lower end. The first support 4 is assumed to be above the oil storage chamber 1 and the oil collecting chamber 3.

[0033] The linear driving mechanism is used for driving the moving seat 5 to move linearly back and forth and can be a hydraulic cylinder, etc. Since the moving distance is long, the length of the hydraulic cylinder will be large if the hydraulic cylinder is used. Therefore, the linear driving mechanism of the application comprises a second motor 21 connected with a horizontal screw rod 22, the screw rod 22 penetrates through the moving seat 5 and is threadedly matched with the moving seat 5, and the moving seat 5 is slidably matched with the first support 4. The second motor 21 drives the screw rod 22 to rotate, and the screw rod 22 drives the moving seat 5 to move linearly under the action of the thread, and the loading basket 2 moves synchronously with the moving seat 5 when the moving seat 5 moves.

[0034] In the prior art, the loading basket 2 can move linearly and lift to enter and exit the oil storage chamber 1 and the oil collecting chamber 3, and at this time, the linear driving mechanism and the lifting mechanism need to be provided on the first support 4, and the equipment requirement is high. Therefore, the application only drives the loading basket 2 to move linearly, and the oil storage chamber 1 and the oil collecting chamber 3 can lift, so that the structure of the first support 4 can be simplified.

[0035] Specifically, the application further comprises a second support 6 and a third support, the oil storage chamber 1 is slidably matched with the second support 6 in the vertical direction, and the oil storage chamber 1 is connected with a first lifting mechanism 8; the third support comprises a solid frame body 7 and a lifting frame body 9, the lifting frame body 9 is slidably matched with the solid frame body 7 in the vertical direction, and the lifting frame body 9 is connected with a second lifting mechanism 10, the oil collecting chamber 3 is arranged on the lifting frame body 9, a circular rotating table 11 is arranged in the oil collecting chamber 3, a positioning cylinder 15 is arranged at the edge of the upper surface of the rotating table 11, a plurality of evenly distributed and radially extending clamping grooves 12 are arranged on the upper surface of the rotating table 11, and a rotating driving mechanism 13 is connected with the lower surface of the rotating table 11; a plurality of clamping plates 14 matched with the clamping grooves 12 are arranged on the lower surface of the loading basket 2.

[0036] ​The first lifting mechanism 8 can adopt a hydraulic cylinder which is vertically fixed on the second support 6 and has an upper end fixedly connected with the bottom of the oil storage chamber 1, so as to push the oil storage chamber 1 to lift. The second lifting mechanism 10 can also adopt a hydraulic cylinder which is fixed on the solid frame 7 and has an upper end fixedly connected with the lifting frame 9, so as to push the lifting frame 9 to lift. The oil collecting chamber 3 is fixedly installed on the lifting frame 9 and can ascend or descend with the lifting frame 9. The rotary table 11 is used for supporting and rotating the loading basket 2, so that the excess oil is thrown into the oil collecting chamber 3 under the action of centrifugal force. The rotary table 11 is rotatably installed in the oil collecting chamber 3. Specifically, a mounting seat 16 can be arranged at the bottom of the oil collecting chamber 3, and the rotary table 11 is installed in the mounting seat 16 through a tapered roller bearing which can bear a large axial load. The inner diameter of the positioning cylinder 15 is slightly larger than the outer diameter of the loading basket 2, so as to position the loading basket 2 and prevent the loading basket 2 from tilting during rotation. The clamping groove 12 and the clamping plate 14 are matched to transmit torque. The positioning cylinder 15 and the rotary table 11 can be provided with a plurality of oil leakage holes, so that the excess oil can flow into the oil collecting chamber 3. The clamping groove 12 and the clamping plate 14 are preferably three and are uniformly distributed.

[0037] The rotary drive mechanism 13 is used for driving the rotary table 11 to rotate, and can adopt a first motor which is fixedly installed on the lifting frame 9 and connected with the rotary table 11 through a transmission shaft 17 penetrating through the bottom plate of the oil collecting chamber 3.

[0038] The loading basket 2 can be connected with the moving seat 5 through common detachable connecting pieces such as bolts. In order to more conveniently and quickly install the loading basket 2 on the moving seat 5 and facilitate the dismounting of the loading basket 2 from the moving seat 5, three evenly distributed lifting lugs 18 are arranged on the top of the loading basket 2, and three connecting rods 19 are arranged on the moving seat 5, the upper end of each connecting rod 19 is hinged to the moving seat 5, and the lower end is hung with a lifting lug 18 through a hook.

[0039] An oil receiving groove 20 is arranged between the oil storage chamber 1 and the oil collecting chamber 3. During the conveying of the loading basket 2 from the oil storage chamber 1 to the oil collecting chamber 3, the excess oil drops downward into the oil receiving groove 20, which can be recycled to avoid waste of oil.

[0040] The oil immersion method of the present application comprises

[0041] The finished gear is put into the loading basket 2, dozens or hundreds of gears can be put into the loading basket 2 at a time, and batch oil immersion is realized. Then the loading basket 2 is connected to the moving seat 5, specifically, the loading basket 2 is lifted to the lower side of the moving seat 5 by using the lifting device, then the three connecting rods 19 are rotated, the hooks at the lower ends of the connecting rods 19 are hung on the lifting lugs 18 at the top of the loading basket 2, then the lifting device is loosened, and the loading basket 2 is supported by the connecting rods 19. The three connecting rods 19 simultaneously support the weight of the loading basket 2, which can ensure the stability of the loading basket 2.

[0042] Then the linear drive mechanism drives the moving seat 5 and the loading basket 2 to move to the upper side of the oil storage chamber 1, the first lifting mechanism 8 is used to push the oil storage chamber 1 to move upward, and the loading basket 2 gradually immerses in the oil liquid in the oil storage chamber 1. When all the gears in the loading basket 2 enter the oil liquid in the oil storage chamber 1, the first lifting mechanism 8 stops running. After the oil immersion is completed, the first lifting mechanism 8 is used to push the oil storage chamber 1 to reset downward.

[0043] Then the linear drive mechanism is used to drive the moving seat 5 and the loading basket 2 to move to the upper side of the oil collecting chamber 3, the second lifting mechanism 10 is used to push the lifting frame body 9 to move upward, and the rotating table 11 rises synchronously with the lifting frame body 9 until the rotating table 11 supports the loading basket 2, and the clamping plate 14 of the loading basket 2 is clamped into the clamping groove 12 of the rotating table 11. At this time, the connecting rod 19 can be rotated to disconnect the loading basket 2 and the moving seat 5. Then the rotating drive mechanism 13 is started to drive the rotating table 11 to rotate, and the rotating table 11 drives the loading basket 2 to rotate through the clamping plate 14. Under the action of centrifugal force, the excess oil liquid is thrown out.

[0044] After the excess oil liquid is removed, the rotating drive mechanism 13 stops running, the loading basket 2 is connected to the moving seat 5 again, and then the second lifting mechanism 10 pushes the lifting frame body 9 to move downward to the initial position, and the gears in the loading basket 2 are taken out.

[0045] The present application adopts the rotating driving of the loading basket 2 to generate centrifugal force, and the excess oil liquid is thrown out under the action of centrifugal force. Compared with static waiting for oil liquid to automatically drop, the efficiency is obviously improved.

[0046] The gears in the loading basket 2 are numerous, and even if all the gears are immersed in the oil, a small amount of gear surface will be blocked by other gears and not adhere to the oil, at which time the oil immersion time needs to be extended, resulting in reduced efficiency. In order to ensure the oil immersion effect and not affect the oil immersion efficiency, the present application is provided with a piston 23 in sliding cooperation with the oil storage chamber 1, which is a stainless steel plate with good sealing performance at the edge and the inner wall of the oil storage chamber 1. The lower surface of the piston 23 is connected to the bottom plate of the oil storage chamber 1 through a spring 24, and the bottom side wall of the oil storage chamber 1 is provided with a plurality of lower oil inlet and outlet ports, and the top side wall of the oil storage chamber 1 is provided with a plurality of upper oil inlet and outlet ports, each lower oil inlet and outlet port is connected to an upper oil inlet and outlet port through an oil pipe 25, and the oil discharge direction of the upper oil inlet and outlet port is perpendicular to the radial direction of the oil storage chamber 1.

[0047] When the oil is immersed, the first lifting mechanism 8 pushes the oil storage chamber 1 to move up and down repeatedly;

[0048] When the oil storage chamber 1 moves upward, after the loading basket 2 contacts the piston 23, the piston 23 moves downward relative to the oil storage chamber 1 under the action of the gravity of the loading basket 2, the spring 24 is compressed, the piston 23 exerts pressure on the oil below the piston 23, the oil reaches the upper side of the piston 23 through the oil pipe 25, and enters the oil storage chamber 1 in a direction perpendicular to the radial direction of the oil storage chamber 1, thereby pushing the oil above the piston 23 to rotate and promote the flow of the oil.

[0049] When the oil storage chamber 1 moves downward, the piston 23 moves upward relative to the oil storage chamber 1 under the action of the spring 24, and the oil above the piston 23 reaches the lower side of the piston 23 through the oil pipe 25.

[0050] The oil storage chamber 1 moves up and down repeatedly, and the piston 23 also moves up and down relative to the oil storage chamber 1 repeatedly, thereby continuously driving the oil to rotate and move vertically, forming a rotational flow, and the oil can enter the stacked gears more quickly in the process of rotational flow, so that all the gear surfaces can adhere to the oil, thereby improving the oil immersion effect and efficiency. In addition, the movement of the piston 23 does not require additional power, and the structure of the oil storage chamber 1 is simple.

[0051] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
