Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment maintenance tools, specifically a disassembly device for adding oil to an oil cup. Background Technology

[0002] Oil cups are an important component of the lubrication system of mechanical equipment. They are used to store lubricating oil and deliver lubricating medium to key components (such as bearings and gears) to ensure the normal operation of the equipment. During equipment maintenance, when the lubricating oil level in the oil cup is too low or the oil quality deteriorates, the oil cup needs to be disassembled regularly for refilling or oil replacement. Currently, oil cup disassembly is mostly done manually by hand or with the aid of ordinary wrenches (such as adjustable wrenches or open-end wrenches). However, this method has significant drawbacks: First, some oil cups, due to long-term use, are affected by oil stains and corrosion, resulting in tight threaded connections with the equipment interface, making manual disassembly difficult and prone to causing hand injuries or fatigue for workers. Second, ordinary wrenches have a small contact area with the outer wall of the oil cup, and since oil cups are mostly made of plastic or thin metal, uneven force during disassembly can easily cause deformation and damage to the outer wall of the oil cup, increasing the cost of oil cup replacement. To address these problems, a disassembly device for refilling oil cups is proposed. Utility Model Content

[0003] To solve the above technical problems, the present invention adopts the following technical solution: a disassembly device for refilling an oil cup, comprising a frame, a fixed shaft fixedly installed on the upper side of the frame, the fixed shaft being connected and fixedly connected to the output end of an external hydraulic cylinder, a movable plate being movably connected to the lower side of the frame, a piston tube being fixedly installed on the movable plate in a symmetrical structure, a piston rod being movably connected inside the piston tube, a fan-shaped plate being fixedly installed at the lower end of the piston rod, and the fan-shaped plate being engaged and fixedly connected to a snap-fit ​​groove opened on the outer wall of the cup.

The size of the snap-fit ​​grooves is adapted to the size of the sector plate, and a threaded tube is fixedly installed at the lower end of the cup body, with the threaded tube corresponding to the position of the oil filling hole.

[0005] Preferably, two connecting rods are fixedly installed on the upper part of the movable plate in a symmetrical structure.

[0017] 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.

[0018] Example: Figures 1-4 As shown, this utility model provides a disassembly device for refilling an oil cup, including a frame 1. A fixed shaft 11 is fixedly installed on the upper side of the frame 1, and the fixed shaft 11 is connected and fixed to the output end of an external hydraulic cylinder. A movable plate 2 is movably connected to the lower side of the frame 1. A piston tube 3 is fixedly installed on the movable plate 2 in a symmetrical structure. A piston rod 32 is movably connected inside the piston tube 3. A sector plate 4 is fixedly installed at the lower end of the piston rod 32. The sector plate 4 is engaged and fixed with a snap-fit ​​groove 51 opened on the outer wall of the cup body 5. Specifically, in this application, when it is necessary to disassemble the oil cup, the sector plate 4 is engaged and fixed with the snap-fit ​​groove 51. At this time, by rotating the corresponding frame 1, the contact relationship between the sector plate 4 and the groove wall of the snap-fit ​​groove 51 can be used to synchronously drive the oil cup to rotate as a whole, thereby achieving efficient disassembly of the oil cup.

[0019] In one embodiment, in this application, two symmetrical snap-fit ​​grooves 51 are formed on the outer wall of the cup body 5. The size of the snap-fit ​​grooves 51 is adapted to the size of the sector plate 4, and a threaded tube 52 is fixedly installed at the lower end of the cup body 5, with the threaded tube 52 corresponding to the position of the oil filling hole. The corresponding oil filling hole is provided on the corresponding external mechanical equipment. By disengaging the threaded engagement between the threaded tube 52 and the oil filling hole, the oil cup can be effectively disassembled.

[0020] Specifically, in this application, two connecting rods 13 are fixedly installed on the upper part of the movable plate 2 in a symmetrical structure. The lower end of the connecting rod 13 extends through the movable plate 2 and is fixedly installed with a fixing block 14 at the lower side position. The upper end of the connecting rod 13 is movably connected to the frame 1. In use, the frame 1 is first connected and fixed to the output end of the external hydraulic cylinder through the fixed shaft 11 to ensure the overall stability of the device. Then, the cup 5 that needs to be disassembled or lubricated is placed in the annular part 22 in the middle of the movable plate 2, so that the diameter of the cup 5 matches the mounting groove 23 in the middle of the annular part 22, achieving initial positioning. At this time, the snap-fit ​​groove 51 on the outer wall of the cup 5 corresponds to the position of the sector plate 4.

[0021] Specifically, in this application, a connecting pipe 31 is fixedly installed at the upper end of the piston tube 3. The connecting pipe 31 is connected to the output end of an external air pump for injecting or evacuating air into the piston tube 3. A snap-fit ​​ring 41 is fixedly installed on the outer wall of the sector plate 4, and the snap-fit ​​ring 41 is connected and fixed to the piston rod 32. Next, the external air pump is started, and air is injected into the piston tube 3 through the connecting pipe 31, pushing the piston rod 32 downward, which in turn drives the sector plate 4 downward until the sector plate 4 is completely snapped into the snap-fit ​​groove 51 on the outer wall of the cup body 5. Since the size of the snap-fit ​​groove 51 is adapted to the size of the sector plate 4, the sector plate 4 can be firmly snapped into the snap-fit ​​groove 51, thereby fixing the cup body 5.

[0022] Furthermore, in this application, the frame 1 has symmetrically arranged sliding grooves 12 on both sides, and sliders 21 are fixedly installed on the outer walls of both sides of the movable plate 2, with the sliders 21 slidingly engaged with the sliding grooves 12. After the cup body 5 is fixed, the external hydraulic cylinder is activated, driving the frame 1 to move upward or downward as a whole through the fixed shaft 11. Since the movable plate 2 is movably connected to the frame 1, and the sliders 21 are fixedly installed on the outer walls of both sides of the movable plate 2, with the sliders 21 slidingly engaged with the symmetrically arranged sliding grooves 12 on both sides of the frame 1, the movable plate 2 can move smoothly up and down with the frame 1. During the up and down movement of the movable plate 2, the cup body 5 also moves up and down, thereby achieving threaded connection or separation with the equipment interface. With the above technical solution, when oiling is required, simply connect the oiling pipe to the threaded pipe 52 at the lower end of the cup body 5 to perform the oiling operation. After oiling is completed, follow the reverse steps to remove the cup body 5 from the device, completing the entire oiling or disassembly process.

[0023] In one embodiment, in this application, a circular ring 22 is fixedly installed in the middle of the movable plate 2. The circular ring 22 has a mounting groove 23 in its middle, and the diameter of the mounting groove 23 matches the diameter of the cup body 5. A fixing ring 24 is also fixedly installed on the outer wall of the circular ring 22, which is used to fix the piston tube 3. Through the above technical solution, in actual use, specifically, the circular ring 22 can accurately position the cup body 5 through the mounting groove 23 in its middle, ensuring the stability of the cup body 5 on the device. At the same time, the fixing ring 24 fixedly installed on the outer wall of the circular ring 22 not only provides a stable support for the piston tube 3 but also ensures the stability of the piston tube 3 during operation, avoiding disassembly or lubrication failures caused by the shaking of the piston tube 3. Furthermore, the design of this device fully considers ease of use and safety. Through the combined use of an external hydraulic cylinder and an air pump, automated fixing and disassembly of the cup body 5 is achieved, greatly reducing the labor intensity of the workers. Meanwhile, the secure and reliable connection between the sector plate 4 and the snap-fit ​​groove 51 effectively prevents safety accidents caused by the cup body 5 slipping during disassembly.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
