Description

Technical Field

[0001] This utility model relates to the technical field of gear transmission maintenance for high-speed trains, specifically, to a scraping device for preventing oil blockage and sticking of sleeves. Background Technology

[0002] The gear transmission system is a key component of the running gear in high-speed trains. It typically has drain plugs and fill plugs to seal the lubricating oil within the gear transmission. During regular gearbox oil changes, the plugs are usually unscrewed manually before replacement, which is laborious and time-consuming due to the tightness of the plugs. While using a robotic arm to unscrew the plugs is problematic, the oil surface often contains oil contaminants, requiring insertion into the tool. This can cause the plug to stick to the tool after unscrewing, necessitating manual shutdown and removal before resuming operation. This disrupts continuous operation and reduces efficiency. Utility Model Content

[0005] In the aforementioned scraping device for preventing oil blockage and sticking to the sleeve, the oil blockage scraping part is a vertical plate, the upper end of the vertical plate is provided with a bending plate, and the end of the bending plate is provided with a locking hole with an opening on one side, so that the oil blockage can be inserted into the locking hole from the side opening, thereby detaching the oil blockage from the oil blockage removal assembly.

[0006] In the above-mentioned scraping device for an oil-blocking sleeve, the guide part is a guide groove, one end of the guide groove is installed at the lower end of the bending plate, so that the card hole is located above the guide groove, a baffle is provided at the end of the guide groove away from the bending plate, and a collection tray is provided below the baffle.

[0007] In the aforementioned scraping device for preventing oil blockage and sticking sleeve, the oil blockage removal assembly includes a base plate installed at the end of a robotic arm, a movable servo motor mounted on the base plate, an oil blockage sleeve mounted on the motor shaft of the servo motor, and an oil blockage cavity provided at the end of the oil blockage sleeve for fitting an oil blockage.

[0009] The beneficial effect of this utility model is that after the robotic arm drives the oil plug removal component to remove the oil plug, the robotic arm extends the oil plug towards and scrapes the oil plug scraping part, so that the oil plug is separated from the oil plug removal component and falls into the guide part and is collected by the collection tray for easy processing of the removed oil plug. During the process, the oil plug removal component on the robotic arm can quickly remove the unscrewed oil plug, preventing the interruption of work and improving work efficiency.

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] Combination Figures 1 to 3The illustrated device for scraping off oil plugs from sleeves includes a main body 1, on which a robotic arm 2 is mounted. An oil plug removal assembly 3 for unscrewing oil plugs 10 is mounted at the output end of the robotic arm 2. An oil plug scraping section is located on one side of the robotic arm 2, and a guide section is provided at one end of the scraping section. This guide section allows the oil plug removal assembly 3 to scrape the unscrewed oil plug 10 off the scraping section, causing the oil plug 10 to fall into the guide section. A collection tray 7 is provided at the output end of the guide section. In this embodiment, after the robotic arm 2 drives the oil plug removal assembly 3 to remove the oil plug 10, the robotic arm 2 extends and scrapes the oil plug 10 towards the scraping section, causing the oil plug 10 to detach from the oil plug removal assembly 3. The oil plug 10 then falls into the guide section and is collected by the collection tray 7 for easy processing of the removed oil plug 10. During this process, the oil plug removal assembly 3 on the robotic arm can quickly detach the unscrewed oil plug 10, preventing disruption to the work's continuity and improving work efficiency.

[0016] Specifically, in this embodiment, the oil plug scraping part is a vertical plate 4. A bending plate 8 is provided at the upper end of the vertical plate 4. A locking hole 9 with an opening on one side is provided at the end of the bending plate 8, so that the oil plug 10 can be inserted into the locking hole 9 from the side opening, so that the oil plug 10 can be removed from the oil plug removal assembly 3. Since the side of the locking hole 9 is open, it is convenient for the robot to drive the oil plug removal assembly 3 to move the oil plug 10 from the opening into the locking hole 9, so that the oil plug 10 is inserted into the locking hole 9. After the robot 2 moves further, the oil plug 10 can be scraped off.

[0017] In this embodiment, the guide part is a guide groove 5. One end of the guide groove 5 is installed at the lower end of the bending plate 8, so that the card hole 9 is located above the guide groove 5. A baffle 6 is provided at the end of the guide groove 5 away from the bending plate 8, and a collection tray 7 is provided below the baffle 6. After the oil plug 10 is scraped off from the oil plug removal assembly 3, the oil plug 10 can fall into the guide groove 5. In this embodiment, the guide groove 5 is inclined, so that the oil plug 10 rolls down to the baffle 6. The baffle 6 is vertically arranged, and the lower end of the baffle 6 is the outlet, so that the oil plug 10 falls into the collection tray 7 from the lower end.

[0018] It is worth noting that the oil plug removal assembly 3 in this embodiment includes a base plate 11 installed at the end of the robot arm 2. A movable servo motor 12 is installed on the base plate 11. An oil plug sleeve 13 is installed on the motor shaft of the servo motor 12. The end of the oil plug sleeve 13 is provided with an oil plug cavity that can be fitted into the oil plug 10. Driven by the robot arm 2, the oil plug sleeve 13 is fitted into the nut end of the oil plug 10. The oil plug 10 can be removed from the gear transmission device of the EMU by rotating the oil plug sleeve 13 driven by the servo motor 12. No manual disassembly is required, saving time and effort.

[0019] In this embodiment, a slider 16 is installed on one side of the servo motor 12, a slide rail 17 is slidably installed on the slider 16, and a cylinder 15 is installed on the slide rail 17. The cylinder 15 is mounted on the base plate 11 through the cylinder seat 14. During the process of rotating the oil plug sleeve 13 to unscrew the oil plug 10, the servo motor 12 can be moved by the cylinder 15 to facilitate the removal of the oil plug 10 from the gear transmission device of the EMU.

[0020] It is also worth noting that the robotic arm 2 in this embodiment is a Wasu collaborative six-axis robot, which is existing technology and will not be described in detail here.
