Description

Technical Field

[0001] This utility model relates to the field of lubrication technology, and in particular to an automatic lubrication device. Background Technology

[0002] A workbench is a device that adjusts its height using a built-in lifting column. It is widely used in industrial production lines, and its core function is to provide an ergonomic and flexible working height to meet the needs of different tasks or users.

[0003] Currently, most worktables rely on manual application of lubricating grease by workers for lubrication and maintenance. Due to the compact internal structure of the worktable and the extremely limited operating space, this traditional lubrication method is not only very inconvenient to operate, but also makes it difficult to ensure that the lubricating grease is evenly and completely covered on the entire friction surface of the lifting column. This uneven lubrication can easily lead to insufficient lubrication in certain areas, which may cause the column to wear more severely in the long run, ultimately affecting the stability and accuracy of the worktable's lifting.

The scraper ring is located inside the sleeve and connected to the bottom of the nozzle. The scraper ring is movably connected to the inner wall of the sleeve. The hydraulic cylinder is disposed on the second partition plate. The output shaft of the hydraulic cylinder passes through the second partition plate and is connected to one end of the connecting rod. The other end of the connecting rod passes through the sleeve and is connected to the scraper ring.

[0008] Furthermore, the sleeve is provided with a transmission groove and at least one guide groove at intervals along the axial direction. The end of the connecting rod away from the hydraulic cylinder passes through the transmission groove and is connected to the scraper ring. The end of the nozzle away from the worktable is located in the guide groove.

[0019] See Figures 1 to 4An automatic lubrication device includes a frame assembly 1, a lubrication assembly 3, a lifting assembly 44, and a rotating assembly 55.

[0020] Specifically, the frame assembly 1 includes a support 11 and a partition assembly 12 mounted on the support 11. The partition assembly 12 includes a first partition 121 and a second partition 122 spaced apart from top to bottom. The first partition 121 has a first hollow portion, and the second partition 122 has a second hollow portion. The second hollow portion is movably connected to a sleeve 2. The first hollow portion and the sleeve 2 form a receiving space for accommodating the worktable 7. Rollers 6 are provided at the bottom of the support 11. The first partition 121 and the second partition 122 spaced apart from top to bottom constitute a stable rigid frame, providing a reliable installation foundation for the lubrication assembly 3. The first hollow portion on the first partition 121 and the second hollow portion on the second partition 122 together form the receiving space for the worktable 7, while the sleeve 2 movably connected to the second hollow portion ensures precise alignment between the core of the device and the lifting column, laying a key structural foundation for achieving uniform and comprehensive automated lubrication, and fundamentally solving the problem of difficult precise positioning for manual lubrication in a compact space. The rollers 6 at the bottom of the bracket 11 give the device flexible mobility, enabling it to be easily moved between different workstations, significantly improving the equipment's versatility and maintenance efficiency.

[0021] Specifically, the lubrication assembly 3 includes an electric push rod 31, a push plate 32, a tank 33, and a nozzle 34. The electric push rod 31 and the tank 33 are respectively arranged on opposite sides of the second partition 122. The push plate 32 is located inside the tank 33. The output shaft of the electric push rod 31 passes through the second partition 122 and the tank 33 and is connected to the push plate 32. The sleeve 2 is movably connected to the nozzle 34, and the nozzle 34 faces the worktable 7. The tank 33 is connected to the nozzle 34 through a pipe, and a detachable cover 331 is provided on the tank 33. Through highly integrated automated design, the traditional manual lubrication method is completely revolutionized. In this embodiment, there are four lubrication assemblies 3, evenly distributed radially along the sleeve 2. The electric push rod 31 drives the push plate 32 to make stable linear motion within the tank 33, accurately and quantitatively pressurizing the lubricating grease through the pipe to the nozzle 34 and evenly spraying it onto the friction surface of the worktable 7, achieving full automation of the lubrication process. This not only significantly improves maintenance efficiency but also fundamentally ensures the uniformity and consistency of lubrication, effectively avoiding localized wear caused by uneven manual application, and greatly guaranteeing the long-term stability and precision of the equipment. The design of the removable cover 331 on the top of the tank 33 makes the replenishment of lubricating grease convenient and efficient, greatly simplifying the daily maintenance of the device.

[0022] Specifically, the lifting assembly 4 includes a hydraulic cylinder 41, a connecting rod 42, and a scraper ring 43. The scraper ring 43 is located inside the sleeve 2 and connected to the bottom of the nozzle 34. The scraper ring 43 is slidably connected to the inner wall of the sleeve 2. The hydraulic cylinder 41 is mounted on the second partition 122. The output shaft of the hydraulic cylinder 41 passes through the second partition 122 and is connected to one end of the connecting rod 42. The other end of the connecting rod 42 passes through the sleeve 2 and is connected to the scraper ring 43. The sleeve 2 is provided with a transmission groove 21 and four guide grooves 22 spaced along the axial direction. The end of the connecting rod 42 away from the hydraulic cylinder 41 passes through the transmission groove 21 and is connected to the scraper ring 43. The end of the nozzle 34 away from the worktable 7 is located in the guide groove 22.

[0023] It should be noted that the hydraulic cylinder 41, used as the drive source, can output a strong and stable linear thrust, which is reliably transmitted to the scraper ring 43 via the connecting rod 42. Its core innovation lies in the collaborative function of the transmission groove 21 and guide groove 22 on the sleeve 2: the connecting rod 42 efficiently transmits the power of the hydraulic cylinder 41 to the scraper ring 43 via the transmission groove 21, while the design of the nozzle 34's bottom embedded in the guide groove 22 ensures that the nozzle 34 maintains its predetermined orientation and trajectory during lifting, preventing deflection or jamming. This ingenious transmission and guidance separation mechanism allows the nozzle 34 to perform stable and smooth reciprocating motion along the axial direction of the lifting column. Combined with the continuous supply of lubrication components 3, this design achieves linear full-coverage lubrication of the column's friction surfaces from top to bottom or bottom to top, completely solving the coverage blind spot problem existing in manual application and fixed-point lubrication. Ultimately, this component significantly improves lubrication quality and reliability by ensuring uniform and complete coverage of lubricant on the column surface, laying a solid mechanical foundation for effectively extending equipment life and maintaining lifting stability and accuracy.

[0024] Specifically, the rotating assembly 5 includes a third motor 51, a main gear 52, and a driven gear ring 53. The third motor 51 is located at the bottom of the second partition 122, and its output shaft passes through the second partition 122 and is connected to the main gear 52. The driven gear ring 53 is fitted onto the outer wall of the sleeve 2, and the main gear 52 meshes with the driven gear ring 53. The top of the sleeve 2 protrudes from the top of the second hollow portion, and the driven gear ring 53 is movably connected to the second hollow portion. By driving the main gear 52 through the third motor 51, the driven gear ring 53 fitted onto the outer wall of the sleeve 2 meshes and drives the driven gear ring 53. This structure can efficiently and smoothly convert power into the circumferential rotational motion of the sleeve 2. The design of the top of the sleeve 2 protruding from the partition ensures that its rotation process does not interfere with the worktable 7. This rotational motion, combined with the axial movement of the lifting assembly 4, drives the nozzle 34 to rotate around the lifting column. This process ensures that the lubricant evenly and continuously covers the entire cylindrical friction surface of the column, fundamentally solving the inherent defect of uneven circumferential coverage in traditional manual or fixed lubrication methods, and achieving true three-dimensional surround lubrication. This effect significantly improves the integrity and consistency of lubrication, playing a decisive role in reducing column wear, ensuring extreme smoothness during lifting and lowering, and maintaining long-term operational accuracy.

[0025] Working principle: When lubrication of the lifting column of the workbench 7 is required, the electric push rod 31 is activated to drive the push plate 32 to slide downward along the inner wall of the tank 33. The push plate 32 then pushes the lubricating grease (in this embodiment, lubricating butter) inside the tank into the pipeline. Four nozzles 34 are arranged radially along the sleeve 2. After the lubricating grease is pushed into the pipeline, it is sprayed onto the surface of the lifting column of the workbench 7 through the nozzles 34. Then, the hydraulic cylinder 41 is activated to drive the slider to move along the transmission groove 21. The slider drives the scraper ring 43 to slide within the guide groove 22 of the sleeve 2, thereby adjusting the axial position of the nozzles 34. Simultaneously, the motor 51 is activated to drive the main gear 52 to rotate. The main gear 52 drives the driven gear ring to rotate, which in turn drives the sleeve 2 to rotate, causing the nozzles 34 to rotate with the sleeve 2, thus changing their radial position and achieving spraying of other areas of the lifting column of the workbench 7. After the sleeve 2 rotates 90°, due to the limitations of the pipeline layout, the control motor 51 reverses, driving the sleeve 2 to rotate 90° in the opposite direction to reset via the main gear 52 and the driven gear ring. It can be understood that after the above spraying process is completed, the hydraulic cylinder 41 is activated to drive the slider to reciprocate within the transmission groove 21. The slider drives the scraper ring 43 to move along the guide groove 22, realizing the reciprocating motion of the scraper ring 43, thereby completing the comprehensive lubrication of the lifting column surface of the worktable 7.

[0026] This invention utilizes an electric push rod 31 to drive a push plate 32, which stably and quantitatively extrudes lubricating grease from the tank 33 through a pipe from the nozzle 34. This process is fully automated, completely replacing the traditional, inefficient, unreliable, and difficult-to-operate manual application method, thereby significantly improving maintenance efficiency and reducing labor costs and operational safety risks. The ingenious design of this device integrates the lubrication component 3 onto the sleeve 2, which is coaxially aligned with the lifting column of the worktable 7. This structure allows the nozzle 34 to be fixed in an optimized, closest lubrication position, ensuring that the sprayed lubricating grease directly and concentratedly covers the critical friction surfaces of the lifting column. Driven by a hydraulic cylinder 41, the nozzle 34 moves stably along the axial direction of the sleeve 2 via a connecting rod 42 and a scraper ring 43. The separate design of the transmission and guide groove 22 ensures that the nozzle 34 has a precise and unbiased trajectory, achieving linear, full-coverage lubrication of the lifting column's friction surfaces, fundamentally eliminating axial lubrication blind spots and significantly improving the uniformity and consistency of lubrication. The motor 51 drives the main gear 52, which in turn drives the driven gear ring 53, efficiently converting power into the circumferential rotation of the sleeve 2. This rotational motion drives the nozzle 34 to move in a circular motion around the column, achieving uniform spraying of the entire cylindrical surface of the column without dead angles, completely solving the problem of uneven circumferential lubrication. This fundamentally solves the problem of uneven and complete manual lubrication in confined spaces, effectively avoiding abnormal wear caused by insufficient local lubrication, significantly extending the service life of the lifting column, and fundamentally ensuring the long-term stability and positioning accuracy of the worktable 7.
