Description

Technical Field

[0001] This utility model relates to the field of transmission component manufacturing, and in particular to a gear oiling device. Background Technology

[0002] In the machinery manufacturing industry, precision transmission components such as gears undergo surface treatment processes after machining, including cleaning, drying, and rust-preventive oiling. Rust-preventive oil forms a uniform and dense protective film on the gear surface, effectively isolating air and moisture, thus ensuring that the components maintain excellent rust-preventive performance over a long period during storage, transportation, and actual use. Currently, the industry commonly uses processes such as immersion, brushing, or oil pouring to ensure that the rust-preventive oil adheres evenly to the gear surface.

[0003] However, most processing enterprises still use traditional manual methods for rust prevention. Taking the most common immersion process as an example, the specific procedure involves operators manually immersing the gears in a container filled with rust-preventive oil, and after thorough immersion, draining or centrifuging to dry them. This manual immersion method has many drawbacks:

[0004] 1. Low operating efficiency, making it difficult to meet the cycle time requirements of mass production;

[0005] 2. High labor costs have increased the operational burden on businesses;

[0006] 3. During operation, the rust-preventive oil is very easy to spill and splash, which will not only contaminate the workers' work clothes and skin, but also contaminate the workshop floor. This will affect the cleanliness of the working environment, pose safety hazards, and long-term accumulation may also cause corrosion damage to the factory facilities.

[0007] Therefore, this case is brought. Utility Model Content

[0008] The purpose of this utility model is to provide a gear oiling device to achieve automated gear oiling, thereby reducing costs and increasing efficiency.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows:

[0010] A gear oiling device, comprising:

[0011] The first fixing base is fixed to the ground;

[0012] An oil immersion tank, wherein a second fixed seat is provided at the center of the bottom surface of the oil immersion tank;

[0013] An oil receiving drum is provided with a third fixed seat at the center of its bottom surface, and an oil outlet pipe with a valve is provided at the bottom of the oil receiving drum.

[0014] The fourth fixing seat is fixed to the ground;

[0015] The first fixing seat, the second fixing seat, the third fixing seat and the fourth fixing seat are all provided with insertion holes at their centers;

[0016] gantry-type robotic arm;

[0017] The loading rod is divided into three parts from top to bottom: a clamping part, a loading part, and a plugging part. The clamping part can be held by a gantry-type robotic arm, the plugging part can be inserted into a plug hole, and the loading part is rod-shaped and is used to pass through the central shaft hole of the gear to be oiled and can be clearance-fitted with the central shaft hole.

[0018] The truss-type manipulator is used to grip the loading rod and move it back and forth between the first fixed seat, the immersion tank, the receiving tank, and the fourth fixed seat.

[0019] Furthermore, the truss-type manipulator includes a truss body, an X-axis lateral movement mechanism is mounted on the truss body, a Y-axis lifting mechanism is mounted on the moving seat of the X-axis lateral movement mechanism, and the manipulator body is mounted on the lifting seat of the Y-axis lifting mechanism.

[0020] The truss body encloses the first fixed seat, the oil immersion tank, the oil receiving tank, and the fourth fixed seat, and the first fixed seat, the oil immersion tank, the oil receiving tank, and the fourth fixed seat are arranged in a straight line along the X direction.

[0021] Furthermore, the robotic arm body includes a rotating part and a clamping part. The rotating part is mounted on the lifting seat of the Y-axis lifting mechanism, and the clamping part is mounted on the rotating end of the rotating part.

[0022] The second fixed seat is rotatably connected to the center of the bottom surface of the oil immersion tank via a bearing, and the third fixed seat is rotatably connected to the center of the bottom surface of the oil receiving tank via a bearing.

[0023] Furthermore, the clamping part includes two opposing clamping plates, each with a protrusion on its opposing surface. The clamped part is rod-shaped, and its sidewall has a groove corresponding to the protrusion.

[0024] Furthermore, the insertion part includes a rod that can be inserted into the insertion hole, and a limiting ring with an outer diameter larger than the insertion hole is provided at the junction of the insertion part and the loading part.

[0025] Furthermore, the loading part is screw-type, and multiple spacer rings are threaded onto the loading part. The gear to be oiled, placed on the loading part, is clamped between two spacer rings.

[0026] Furthermore, the spacer ring includes an internally threaded ring body, with four upper support pillars extending upward from the outer periphery of the top surface of the ring body, and four lower support pillars extending downward from the bottom surface of the ring body. The ends of the upper and lower support pillars are provided with rubber pads.

[0027] Furthermore, the loading part is provided with an axial through hole and a radial through hole. There is only one axial through hole, which is arranged along the central axis of the loading part rod. There are multiple radial through holes, which are arranged along the length of the loading part rod.

[0028] Furthermore, an oil receiving plate is provided between the oil immersion tank and the oil receiving tank, and the oil receiving plate is inclined from the oil receiving tank to the oil immersion tank.

[0029] The advantages of this utility model are:

[0030] 1. By using a gantry-type robotic arm to automatically transport and load the gears, the gears can be immersed in oil, drained, or splashed with oil. This method is highly automated and can oil multiple gears at once, greatly improving efficiency.

[0031] 2. The loading rod can also rotate when it is clamped. The rotation function helps the gears to be more thoroughly immersed in oil. At the same time, the rotation function can not only remove excess anti-rust oil from the gear surface, but also make the anti-rust oil adhering to the gear surface more even.

[0032] 3. As a key component in this gear oiling device, the loading rod's multi-segment structure design (clamping part, loading part, and insertion part) enables stable clamping and precise positioning with the gantry-type robot. The screw-type loading part, in conjunction with the spacer ring, can simultaneously fix multiple gears, improving work efficiency. The axial and radial through-hole design facilitates the penetration of anti-rust oil, providing reliable support for achieving efficient and automated gear oiling. Attached Figure Description

[0049] The present invention will be further described in detail below with reference to embodiments. It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer" used in this document indicate the orientation or positional relationship based on the attached embodiments. Figure 1The orientation or positional relationship shown in the coordinate system is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0050] This embodiment proposes a gear oiling device, such as... Figure 1 As shown, it includes a first fixed seat 1, an oil immersion tank 2, an oil receiving tank 4, a fourth fixed seat 6, a truss-type manipulator 7, and a loading rod 8.

[0051] Referring to Figures 1 and 9, the truss-type manipulator 7 includes a truss body 701. An X-axis lateral movement mechanism 702 is mounted on the truss body 701. A Y-axis lifting mechanism 703 is mounted on the moving seat of the X-axis lateral movement mechanism 702. The manipulator body is mounted on the lifting seat of the Y-axis lifting mechanism 703. The manipulator body includes a rotating part 704 and a clamping part 705. The rotating part 704 is mounted on the lifting seat of the Y-axis lifting mechanism 703, and the clamping part 705 is mounted on the rotating end of the rotating part 704. The truss body 701 encloses the first fixed seat 1, the oil immersion tank 2, the oil receiving tank 4, and the fourth fixed seat 6, which are arranged sequentially along the X-axis. The truss-type manipulator 7 is used to clamp and move the loading rod 8 back and forth between the first fixed seat 1, the oil immersion tank 2, the oil receiving tank 4, and the fourth fixed seat 6.

[0052] refer to Figure 1 , Figure 6 and Figure 7 The first fixing seat 1 is fixed to the ground. A second fixing seat 3 is located at the center of the bottom surface of the oil immersion tank 2, and the second fixing seat 3 is rotatably connected to the center of the bottom surface of the oil immersion tank 2 via a bearing. A third fixing seat 5 is located at the center of the bottom surface of the oil receiving tank 4, and the third fixing seat 5 is rotatably connected to the center of the bottom surface of the oil receiving tank 4 via a bearing. The bottom of the oil receiving tank 4 is equipped with an oil outlet pipe 401 with a valve. A fourth fixing seat 6 is fixed to the ground. Each of the first fixing seat 1, the second fixing seat 3, the third fixing seat 5, and the fourth fixing seat 6 has a central insertion hole 9.

[0053] refer to Figure 2 and Figure 3 The loading rod 8 is divided into three parts from top to bottom: a clamping part 801, a loading part 802, and a plug-in part 803. The clamping part 801 can be held by the gantry-type robot arm 7, the plug-in part 803 can be inserted into the plug hole 9, and the loading part 802 is rod-shaped and is used to pass through the central shaft hole of the gear 11 to be oiled and can be clearance-fitted with the central shaft hole.

[0054] As a preferred option, such as Figure 2 and Figure 9As shown, the clamping part 705 includes two opposing clamping plates 7051, each with a protrusion 7052 on its opposing surface. The clamped part 801 is rod-shaped, and its sidewall has a groove 8011 corresponding to the protrusion 7052. The design of the groove 8011 and the protrusion 7052 increases the stability during clamping and prevents the loading rod 8 from falling off during clamping and conveying.

[0055] As a preferred option, such as Figure 2 As shown, the plug-in part 803 includes a rod that can be inserted into the plug hole 9, and a limiting ring 8031 ​​with an outer diameter larger than the plug hole 9 is provided at the junction of the plug-in part 803 and the loading part 802. The length of the plug-in part 803 is different for different models of loading rods 8, and the plug hole 9 is designed to accommodate the plug-in part of the maximum length. The design of the limiting ring 8031 ​​can prevent the loading rod 8 from falling into the plug hole 9 excessively, and instead make the plug-in part 803 fall into the plug hole 9 exactly.

[0056] refer to Figure 2 and Figure 3 The loading part 802 is a screw type, and multiple spacer rings 804 are threadedly connected to the loading part 802. The gear 11 to be oiled, placed on the loading part 802, is clamped and fixed between two spacer rings 804. The spacer rings 804 can fix the gear 11 to be oiled on the loading rod 8. Figure 4 and Figure 5 As shown, the spacer ring 804 includes an internally threaded ring body, with four upper support pillars 8041 extending upward from the outer periphery of the top surface of the ring body, and four lower support pillars 8042 extending downward from the bottom surface of the ring body. Rubber pads 8043 are provided at the ends of the upper and lower support pillars 8041 and 8042. Both the upper support pillars 8041 and 8042 are thin rod-type designs, which can reduce the contact area between the spacer ring 804 and the gear 11 to be oiled, allowing the rust-preventive oil to fully contact the surface of the gear 11 to be oiled. The design of the rubber pads 8043 can protect the gear surface from damage.

[0057] In addition, the loading part 802 is provided with an axial through hole 8021 and a radial through hole 8022. There is one and only one axial through hole 8021, which is arranged along the central axis of the loading part 802 rod. There are multiple radial through holes 8022, which are arranged along the length of the loading part 802 rod. One end of each radial through hole 8022 is connected to the axial through hole 8021, and the other end is connected to the outside. The design of the axial through hole 8021 and the radial through hole 8022 allows more rust-preventive oil in the barrel to flow into the gap between the loading rod 8 and the shaft hole of the gear 11 to be oiled through the axial through hole 8021 and the radial through hole 8022, so as to achieve sufficient oiling of the gear.

[0058] The process of using this oiling device is as follows:

[0059] S1. As Figure 8 As shown, one operator inserts the loading rod 8 into the first fixed seat 1 and holds it, while another operator places the spacer ring 804 and the gear 11 to be oiled onto the loading rod 8 alternately (the spacer ring 804 is screwed into the loading rod 8, and the gear 11 to be oiled is directly inserted through the intermediate shaft hole). Figure 3 As shown, four gears 11 to be oiled and five spacer rings 804 can be placed on a loading rod 8, so that the uppermost radial through hole 8022 can be exposed;

[0060] S2. For example Figure 9 As shown, the robotic arm moves in the X direction to directly above the first fixed base 1, as... Figure 10 As shown, the robotic arm descends in the Y direction and clamps the loading rod 8;

[0061] S3. For example Figure 11 and 12 As shown, the truss-type robot 7 moves the loading rod 8 above the oil immersion tank 2 and lowers it so that the lower end of the loading rod 8 is inserted into the second fixed seat 3;

[0062] S4. The oil soaking tank 2 is filled with rust-preventive oil. After the loading rod 8 is placed in the tank, the rust-preventive oil gradually soaks the gear 11 to be oiled. In this embodiment, the shaft hole of the gear 11 to be oiled is slightly larger than the rod body of the loading rod 8, which also allows the rust-preventive oil to enter the gap between the shaft hole and the rod. However, when the worker places the gear 11 to be oiled, he will not accurately adjust the position of the gear, so that the gap between the shaft hole and the rod may only exist on one side, and the rust-preventive oil on the other side cannot enter. At this time, the rust-preventive oil can flow into the gap between the loading rod 8 and the shaft hole of the gear 11 to be oiled through the axial through hole 8021 and the radial through hole 8022, so as to achieve sufficient oiling of the gear (in step S1, the uppermost radial through hole 8022 is exposed, which can facilitate the entry of rust-preventive oil).

[0063] Furthermore, the robotic arm body can be set to rotate intermittently and slowly. The rotation function helps the gears to be better immersed in oil, thus improving the oiling efficiency.

[0064] S5. For example Figure 13 As shown, after the oil has been applied for a certain period of time, the gantry robot 7 lifts the loading rod 8 and places it into the oil receiving tank 4, so that the lower end of the loading rod 8 is inserted into the third fixed seat 5; excess rust-preventive oil on the gear drips into the oil receiving tank 4, and the rust-preventive oil collected in the oil receiving tank 4 can be discharged and recycled through the oil outlet pipe.

[0065] To further improve the oil draining effect, the robotic arm body can rotate continuously and rapidly inside the oil receiving tank 4. Relying on centrifugal force, it can throw off the excess anti-rust oil on the gear surface. At the same time, the rotation function can also make the anti-rust oil adhering to the gear surface more even.

[0066] Additionally, during the transfer of the loading rod from the immersion tank to the receiving tank, some rust-preventive oil will drip onto the ground between the two tanks, causing waste and pollution. Preferably, such as... Figure 1 As shown, in this embodiment, an oil receiving plate is set between the oil immersion tank and the oil receiving tank, and the oil receiving plate is inclined from the oil receiving tank to the oil immersion tank. In this way, the dripping rust-preventive oil will be caught by the oil receiving plate and guided back into the oil immersion tank.

[0067] S6. After a certain period of time, the gantry robot 7 lifts the loading rod 8 and places it on the fourth fixed seat 6. At this time, the operator holds the loading rod 8, the gantry robot 7 releases its grip on the loading rod 8, and returns to the first fixed seat 1 to carry out the next round of conveying. The operator removes the oiled gear from the loading rod 8.

[0068] The above embodiments are only used to explain the concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
