Description

Technical Field

[0001] This utility model relates to the field of torque sensor processing tooling, and in particular to a lubricating grease coating device. Background Technology

[0002] In the production process of torque sensors, lubricating oil needs to be applied to the workpiece. Lubricating grease coating equipment is an industrial device used to uniformly and precisely apply lubricating grease to designated locations on the workpiece. However, most existing lubricating grease coating equipment suffers from the following problems: Firstly, it is difficult to achieve precise coating, resulting in grease not being applied accurately to the designated location, affecting the performance and service life of the workpiece. This is especially true for workpieces requiring high precision in coating location, where existing equipment struggles to meet their needs. Secondly, existing equipment is prone to grease leakage during the coating process, not only wasting grease but also potentially polluting the equipment and the surrounding environment, increasing cleaning and maintenance costs. Utility Model Content

[0003] This invention proposes a fully automatic lubricating grease coating device, which solves the problem in the prior art that lubricating grease cannot be accurately coated onto the designated position of the workpiece.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A fully automatic lubricating grease coating device includes a worktable with an oil storage tank and a limiting fixture. The bottom of the oil storage tank is connected to a telescopic tube, and the bottom of the telescopic tube is connected to a conical lifting extruder. The lifting extruder is connected to an oil squeezing device. The larger end of the lifting extruder is close to the oil storage tank. The conical surface array of the lifting extruder has multiple oil outlets. A fixed cylinder is located below the oil squeezing device. Multiple guide pillars are fixed to the inner wall of the fixed cylinder. The axis of the guide pillars coincides with the radius of the fixed cylinder. Sector-shaped blocks slide along the guide pillars. Guide springs are sleeved on the guide pillars. The top of each sector-shaped block has an arc-shaped concave surface that abuts against the conical surface of the lifting extruder. Oil guide holes are provided on the sector-shaped blocks. When the lifting extruder pushes the sector-shaped blocks to compress the guide springs through the cooperation of the conical surface and the concave surface, the oil guide holes align with the oil outlets. The bottom end of the oil guide holes faces the limiting fixture.

[0006] Furthermore, the oil extrusion device includes a connecting rod that passes through a telescopic tube. The bottom end of the connecting rod is connected to a lifting extrusion head, and the top end of the connecting rod is connected to a lifting rod. A push plate is fitted onto the lifting rod, and the circumference of the push plate is sealed against the inner wall of the oil storage tank. Inside the oil storage tank, the push plate is sealed against the inner wall of the oil storage tank, preventing external contaminants such as dust and impurities from entering the grease, ensuring the cleanliness of the grease, and thus improving the reliability of the coating operation and the coating quality of the workpiece.

[0007] Furthermore, the connecting rod is connected to the lifting rod via a snap-fit ​​rod. The side wall of the snap-fit ​​rod is fixed with an array of right-angled triangular limiting teeth. One right-angled side of each limiting tooth is fixedly connected to the side wall of the snap-fit ​​rod, and the other right-angled side is close to the telescopic tube. The push plate is fitted onto the snap-fit ​​rod through a limiting hole. A sliding groove is provided on the side wall adjacent to the limiting hole and the limiting teeth. A sealing sliding strip is fixed on the side wall of the limiting hole away from the limiting teeth. A limiting plate slides within the sliding groove. The bottom end of the limiting plate has a chamfered surface that abuts against the inclined surface of the limiting teeth. A limiting spring is provided between the limiting plate and the push plate. Precise adjustment of the coating position can be achieved by using a sector block to drive the oil guide hole, meeting the coating requirements of different workpieces and improving the versatility and flexibility of the equipment.

[0008] Furthermore, the bottom end of the fixed cylinder is connected to a barrel-shaped scraper bin via multiple connecting rods. A gap exists between the top of the scraper bin and the sector-shaped blocks. An annular scraper is fixed inside the scraper bin, with its top end abutting against the bottom surface of the sector-shaped blocks. When a guide spring pushes the sector-shaped blocks closer together, the oil guide hole is positioned within the scraper. The scraper bin facilitates the recycling of lubricating grease.

[0009] Furthermore, the fixed cylinder is detachably connected to the worktable by bolts. The fixed cylinder and extruder can be easily removed by loosening the bolts, facilitating cleaning and maintenance.

[0010] Furthermore, a robotic arm is installed on one side of the workbench, and a conveyor belt is installed within the gripping range of the robotic arm. The robotic arm, in conjunction with the limiting fixture, enhances the overall operational stability of the equipment, reduces the failure rate, and further improves production efficiency and economic benefits, providing strong support for the enterprise's transformation towards automated and intelligent production.

[0011] The beneficial effects of this technical solution are as follows: This utility model precisely controls the movement of the sector block by cooperating the conical surface of the lifting extrusion head with the concave surface of the sector block, aligning the oil guide hole with the oil outlet, and achieving uniform and precise coating of lubricating grease onto the designated position of the workpiece, meeting the requirements of workpieces with high coating position accuracy; the lowering of the lifting extrusion head, grease coating, raising of the lifting extrusion head, and automatic reset of the sector block can significantly shorten the processing cycle of the workpiece and improve the production capacity of the enterprise; after the sector block resets, the oil outlet can be sealed to prevent grease leakage, ensure equipment cleanliness, and reduce waste.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4As shown, a fully automatic lubricating grease coating device includes a workbench 1, on which an oil storage tank 2 and a limiting fixture 12 are provided. A telescopic pipe 3 is connected to the bottom end of the oil storage tank 2, and a conical lifting extruder 4 is connected to the bottom end of the telescopic pipe 3. An oil squeezing device is connected to the lifting extruder 4, with its larger end close to the oil storage tank 2. The conical surface of the lifting extruder 4 has multiple oil outlets 5. A fixed cylinder 6 is located below the oil squeezing device, and multiple guide posts 7 are fixed to the inner wall of the fixed cylinder 6. The axis of column 7 coincides with the radius of fixed cylinder 6. A sector block 8 slides along the guide column 7. A guide spring 9 is sleeved on the guide column 7. Each sector block 8 has an arc-shaped concave surface 10 at its top, which abuts against the conical surface of the lifting extrusion head 4. An oil guide hole 11 passes through the sector block 8. When the lifting extrusion head 4 pushes the sector block 8 to compress the guide spring 9 through the cooperation of the conical surface and the concave surface 10, the oil guide hole 11 can correspond to the oil outlet 5. The bottom end of the oil guide hole 11 faces the limiting fixture 12. The limiting fixture 12 is existing technology and can limit the workpiece by the axial direction of the workpiece. The telescopic tube 3 is existing technology.

[0023] During use, the workpiece to be processed is placed in the limiting fixture 12, which can firmly limit the workpiece axially to prevent displacement during coating. After the equipment is started, the oil extrusion device delivers the lubricating grease in the oil storage tank 2 to the lifting extrusion head 4 through the telescopic pipe 3. As the lifting extrusion head 4 descends, its conical surface contacts the concave surface 10 of the sector block 8 and applies force. Part of this force is decomposed into component forces, which push the sector block 8 to slide along the guide column 7, thereby compressing the guide spring 9 and allowing the sector block 8 to move to the designated position. This facilitates the alignment of the oil guide hole 11 on the sector block 8 with the oil outlet 5 of the lifting extrusion head 4. At this time, the lubricating grease flows out from the oil outlet 5 and is evenly coated onto the workpiece through the oil guide hole 11. After the coating of the conical surface of the lifting extrusion head 4 is completed, the lifting extrusion head 4 is controlled to rise. The lifting extrusion head 4 drives the oil outlet 5 to move upward, while the sector block 8 drives the oil guide hole 11 to move along the axis of the guide column 7, thereby disconnecting the oil outlet 5 from the oil guide hole 11. The sector block 8 can seal the oil outlet 5 by abutting against the conical surface of the lifting extrusion head 4 through the concave surface 10, preventing the lubricating grease from leaking. The sector block 8 is reset under the push of the guide spring 9, completing a complete coating operation and preparing for the next operation. By cooperating with the conical surface of the lifting extrusion head 4 and the recessed surface 10 of the sector block 8, the movement of the sector block 8 is precisely controlled, aligning the oil guide hole 11 with the oil outlet 5. This ensures that the lubricating grease is evenly and accurately coated onto the designated position of the workpiece, meeting the requirements of workpieces with high coating position accuracy. The descent of the lifting extrusion head 4, grease coating, the rise of the lifting extrusion head 4, and the automatic reset of the sector block 8 can significantly shorten the workpiece processing cycle and improve the company's production capacity. After the sector block 8 is reset, the oil outlet 5 can be sealed to prevent grease leakage, ensure equipment cleanliness, and reduce waste.

[0024] like Figure 4-7 As shown, the oil extrusion device includes a connecting rod 13, which passes through the telescopic tube 3. The bottom end of the connecting rod 13 is connected to the lifting extrusion head 4, and the top end of the connecting rod 13 is connected to a lifting rod 14. A push plate 15 is sleeved on the lifting rod 14, and the circumference of the push plate 15 is sealed against the inner wall of the oil storage tank 2. The lifting rod 14 is a conventional hydraulic push rod, etc.

[0025] When the lifting rod 14 moves downward, the telescopic tube 3 extends accordingly. Under the action of gravity and the weight of the push plate 15 itself, the lubricating grease in the oil storage tank 2 is transported to the lifting extrusion head 4 through the telescopic tube 3. The presence of the push plate 15 not only applies a certain pressure to the lubricating grease, but also effectively prevents the grease from being contaminated, making the delivery of the lubricating grease smoother and more stable. At the same time, it ensures the cleanliness of the grease, improves the reliability of the coating operation and the coating quality of the workpiece.

[0026] like Figure 4-7 As shown, the connecting rod 13 is connected to the lifting rod 14 via the snap-fit ​​rod 16. The side wall of the snap-fit ​​rod 16 is fixed with an array of right-angled triangular limiting teeth 17. One right-angled side of the limiting teeth 17 is fixedly connected to the side wall of the snap-fit ​​rod 16, and the other right-angled side of the limiting teeth 17 is close to the telescopic tube 3. The push plate 15 is sleeved on the snap-fit ​​rod 16 through a limiting hole. The side wall adjacent to the limiting hole and the limiting teeth 17 is provided with a sliding groove 18. A sealing sliding strip is fixed to the side wall of the limiting hole away from the limiting teeth 17. A limiting plate 19 slides within the sliding groove 18. The bottom end of the limiting plate 19 has a chamfered surface that abuts against the inclined surface of the limiting teeth 17. A limiting spring is provided between the limiting plate 19 and the push plate 15. The sealing sliding strip is existing technology.

[0027] When the lifting rod 14 moves downward, the limiting spring pushes the limiting plate 19, causing the limiting plate 19 to be positioned between the limiting teeth 17. The right-angled edge of the limiting teeth 17 abuts against the top surface of the limiting plate 19. When lubricating grease needs to be applied, the lifting rod 14 can drive the push plate 15 to move downward. The push plate 15 slides downward in the oil storage tank 2, squeezing out the lubricating grease from the oil storage tank 2. After a single operation is completed, the lifting rod 14 moves upward, and the chamfered surface of the limiting plate 19 slides along the inclined surface of the limiting teeth 17, allowing the limiting plate 19 to overcome the elastic force of the limiting spring and slide into the sliding groove 18. At this time, a single limiting tooth 17 can pass through the limiting hole. Through the guiding effect of the inclined surface, the linear movement of the lifting rod 14 is converted into the lateral sliding of the limiting plate 19, thereby allowing the limiting plate 19 to overcome the elastic force of the limiting spring and gradually slide into the sliding groove 18 of the push plate 15. Since the push plate 15 and the snap-fit ​​rod 16 are slidably connected by a sealing sliding strip, grease leakage is avoided and the grease can be continuously and evenly delivered to the coating area, thus improving the quality and efficiency of coating.

[0028] like Figure 2 ,3 As shown, the bottom end of the fixed cylinder 6 is connected to a barrel-shaped scraper bin 20 via multiple connecting rods. A gap exists between the top of the scraper bin 20 and the fan-shaped blocks 8. An annular scraper 21 is fixed inside the scraper bin 20, with the top of the scraper 21 abutting against the bottom surface of the fan-shaped blocks 8. When the guide spring 9 pushes the fan-shaped blocks 8 closer together, the oil guide hole 11 is placed inside the scraper 21. During the grease coating process, the grease flows from between the connecting rods to the area to be coated on the workpiece. After the coating is completed, or when the type of lubricating grease needs to be changed, the guide spring 9 pushes the fan-shaped blocks 8 closer together, and the oil guide hole 11 is placed inside the scraper 21. At this time, excess grease remaining in the oil guide hole 11 and other areas will, under the action of gravity and the guidance of the scraper 21, converge back into the scraper bin 20 through the oil guide hole 11, achieving efficient grease recovery. The barrel-shaped structure of the scraper bin 20 facilitates centralized grease collection, avoids grease residue and waste inside the equipment, improves grease utilization, and reduces production costs for enterprises.

[0029] like Figure 3 As shown, the fixed cylinder 6 is detachably connected to the worktable 1 by bolts 22. When production needs change, such as adjusting the extrusion volume or adapting to different workpieces, different specifications of extruders or fixed cylinders 6 can be quickly replaced by removing bolts 22, greatly increasing the production flexibility of the equipment and enabling it to better match diverse production scenarios.

[0030] like Figure 1 As shown, a robotic arm 23 is provided on one side of the workbench 1, and a conveyor belt is provided within the gripping range of the robotic arm 23. Both the robotic arm 23 and the conveyor belt are existing technologies. The form of the robotic arm 23 is not limited; it can place workpieces onto or remove them from the limiting fixture 12. The robotic arm 23 can accurately grip the workpieces to be processed according to a preset program and transport them to the limiting fixture 12 without frequent manual intervention, greatly improving work efficiency and accuracy. Especially in mass production, it can reliably ensure high output and high quality. The collaborative operation of the robotic arm 23 and the conveyor belt significantly reduces labor costs and the consumption of manpower in repetitive handling and positioning tasks, allowing enterprises to invest more resources in key areas such as technology research and development and quality control.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
