[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] By providing a single-link closed-frame lubrication device in the embodiments of the present application, the problems in the prior art of the single-link closed-frame lubrication device are solved. Usually, the lubrication points at the slider position and the nut seat position are independent, which increases the number of oil pipes. There is instability in the connection between the oil pipes and each lubrication point, and it is easy to loosen or become disengaged. The disassembly and assembly at the connection position are not convenient enough, resulting in inconvenient maintenance at the oil pipe joint.
[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.
[0025] The embodiments of the present utility model disclose a single-link closed-frame lubrication device. According to the attached Figures 1-5 As shown, it includes a moving guide rail 2 arranged on a static guide rail 1. A driving lead screw 11 is provided on the static guide rail 1. A first lubrication cavity 201 is arranged inside the moving guide rail 2. A nut seat 21 meshing with the driving lead screw 11 is arranged on the side of the moving guide rail 2. A second lubrication cavity 211 is arranged inside the nut seat 21;
[0026] A docking seat 3 is arranged on the moving guide rail 2, and a circulating oil pipe 4 is installed on the docking seat 3;
[0027] An insertion pipe 41 clamped inside the docking seat 3 is arranged on the circulating oil pipe 4. A reinforcing sleeve 42 is arranged outside the insertion pipe 41. A locking mechanism 5 for locking the position of the reinforcing sleeve 42 is arranged on the docking seat 3;
[0028] The device improves the moving guide rail 2 by establishing a lubrication channel between the moving guide rail 2 and the nut seat 21. Through the first lubrication cavity 201 and the second lubrication cavity 211, an oil film contact surface is established at the transmission position between the moving guide rail 2 and the nut seat 21, reducing the resistance at the transmission position and improving the system stability. At the same time, the connection position between the circulating oil pipe 4 and the moving guide rail 2 is improved to ensure the firmness of the connection position. With the design of the locking mechanism 5, the disassembly and assembly of the circulating oil pipe 4 are convenient and easy to maintain, meeting the usage requirements.
[0029] The locking mechanism 5 includes a guide rod 51 fixedly connected to the docking seat 3 and an adjusting block 52 movably clamped on the guide rod 51. A clamping block 53 is provided on the adjusting block 52, and a locking groove 421 is formed on the reinforcing sleeve 42. The clamping block 53 is movably clamped in the locking groove 421. A baffle 54 is fixedly connected to the guide rod 51, and a threaded rod 55 is threadedly connected to the baffle 54. The threaded rod 55 is rotatably connected to the adjusting block 52.
[0030] The structure of the locking mechanism 5 is simple and the operation is convenient. When connecting the docking seat 3 and the circulating oil pipe 4, directly dock the insertion pipe 41 with the docking seat 3. After docking, the reinforcing sleeve 42 is also clamped inside the docking seat 3. At this time, rotate the threaded rod 55, so that the threaded rod 55 moves spirally along the baffle 54 and pushes the adjusting block 52 to move. The adjusting block 52 drives the clamping block 53 to move, so that the clamping block 53 is inserted into the locking groove 421, thereby realizing the fixation of the positions of the reinforcing sleeve 42 and the insertion pipe 41, and thus making the interface between the circulating oil pipe 4 and the docking seat 3 fixed and the connection stable, and the interface position is not easy to loosen.
[0031] A sealing pipe 31 is provided inside the docking seat 3. The insertion pipe 41 is movably inserted into the sealing pipe 31. A rubber ring 32 is provided between the reinforcing sleeve 42 and the sealing pipe 31. When the interface position between the circulating oil pipe 4 and the docking seat 3 is docked, the insertion pipe 41 is inserted into the inside of the docking seat 3 to form a preliminary seal. Then, with the clamping design of the reinforcing sleeve 42 and the sealing pipe 31, a secondary seal is realized. Therefore, the connection between the circulating oil pipe 4 and the docking seat 3 has good sealing performance. When the reinforcing sleeve 42 and the sealing pipe 31 are clamped, the rubber ring 32 is extruded, improving the sealing performance and making the interface connection stable.
[0032] The first lubrication hole 202 is provided inside the first lubrication cavity 201, and the second lubrication hole 212 is provided inside the second lubrication cavity 211. The first lubrication hole 202 and the second lubrication hole 212 respectively penetrate the oil in the first lubrication cavity 201 and the second lubrication cavity 211, so as to facilitate the movement of the lubricating oil inside the moving guide rail 2 and the nut seat 21.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification only illustrate the principles of the present utility model.
