Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a machine tool linear guide lubrication oil pipe loading and unloading structure. Background Technology

[0002] Machine tools are widely used processing equipment in the market. Linear guides are a common structural form for guiding the movement of coordinate axes in machine tools. The operation of linear guides requires a stable supply of lubricating oil. For medium and large machine tools, especially those with multiple linear guides (more than two) and long-stroke coordinate axes, a large number of sliders are arranged on the linear guides, which brings considerable difficulties to fixing the lubrication lines of the linear guides and sliders. Figure 8 As shown, the linear guide rails and their sliders are installed in the middle position. The lubricating oil pipes need to be installed on the linear guide rail sliders first, and then the worktable is installed on the linear guide rail sliders to complete the overall assembly of this part. As can be seen from the figure, the lubricating oil pipes of the two linear guide rails on both sides are located on the outside and are relatively easy to fix. However, the lubricating oil pipes of the two middle linear guide rails are covered by the worktable and cannot be fixed with pipe clamps. Currently, the method used is to leave the oil pipes in this area suspended and unfixed. This method causes the following problems:

[0003] 1. During the operation of the machine tool, the oil pipes may vibrate. Over time, this can cause the oil pipes and joints to loosen, resulting in poor lubrication and oil leakage.

[0004] 2. During the operation of the machine tool, the vibration of the oil pipe causes the oil pipe and its joint to fold repeatedly. Over a long period of time, this will cause damage to the oil pipe, resulting in poor lubrication and oil leakage.

[0005] 3. The oil pipe may bend and deform, causing it to scrape against or even interfere with other parts of the machine tool, resulting in damage to the oil pipe and making it unable to perform its function of lubricating the linear guide.

[0006] Therefore, we provide a mounting and dismounting structure for the lubricating oil pipe of a machine tool linear guide. Utility Model Content

[0007] The purpose of this utility model is to provide a machine tool linear guide lubrication oil pipe mounting and dismounting structure to solve the safety hazards that may be caused by the current suspended installation of lubrication oil pipe in the middle part.

[0008] This utility model can be achieved through the following technical solution: a machine tool linear guide lubricating oil pipe loading and unloading structure, including a machine bed and a worktable slidably mounted on the machine bed, the bottom of the worktable distributing the lubricating oil pipe to the slider of the linear guide through connecting pipe fittings, and the lubricating oil pipe in the internal area of ​​the machine bed being fixed by an oil pipe fixing assembly fixed to the bottom of the worktable;

[0009] The oil pipe fixing assembly includes a fixed plate fixed to the worktable and a movable plate located on one side of the fixed plate and rotatably connected to it. A spring is provided between the upper parts of the fixed plate and the movable plate. The two ends of the spring abut against the fixed plate and the movable plate respectively and maintain a certain elastic force. The bottom of the fixed plate and the movable plate cooperate to clamp the lubricating oil pipe under the action of the elastic force.

[0010] The loading and unloading structure also includes an oil pipe loading and unloading rod, with an installation groove at one end and a disassembly ramp at the other end, for the installation and disassembly of lubricating oil pipes.

[0011] A further technical improvement of this utility model is that: a circular groove is provided on one side of the fixed plate, and a circular protrusion is provided on the opposite side of the movable plate and the fixed plate. The circular protrusion and the circular groove are installed and matched together, and the movable plate can rotate around the joint surface of the two at a certain angle.

[0012] A further technical improvement of this utility model is that a stud is inserted inside the spring, the stud is inserted from one side of the fixed plate and passes through the movable plate, and a nut is threaded to the end of the stud, which prevents the stud from coming out and maintains the spring in a certain compressed state.

[0013] A further technical improvement of this utility model is that: the lower part of the movable plate and the fixed plate are provided with inclined surfaces that are far apart from each other, and semi-circular grooves are opened at the root of the inclined surfaces to form a circular clamping groove.

[0014] A further technical improvement of this utility model is that, when installing the lubricating oil pipe, the mounting groove of the oil pipe loading and unloading rod is used to restrict the position of the lubricating oil pipe, and the lubricating oil pipe is lifted into the clamping groove by lever principle.

[0015] A further technical improvement of this utility model is that: when disassembling the lubricating oil pipe, the disassembly inclined surface is inserted between the bottom surface of the workbench and the lubricating oil pipe, so as to force the lubricating oil pipe out of the clamping groove with downward pressure.

[0016] A further technical improvement of this utility model is that a pad is installed on the bed, and the pad is located below the oil pipe fixing assembly, providing a fulcrum for the oil pipe loading and unloading rod to adjust the loading and unloading angle.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The loading and unloading structure of this utility model is pre-installed and fixed on the bottom surface of the machine tool's worktable. After the bed lubricating oil pipe is installed and arranged, the worktable is installed on the linear guide slider. Then, this structure is used to install and fix the lubricating oil pipe inside the machine tool, which is difficult to fix, onto the oil pipe fixing assembly.

[0019] The oil pipe fixing assembly, through the cooperation design of spring and movable plate, realizes the automatic clamping and release of the lubricating oil pipe inside the machine bed, which solves the problem that traditional standard pipe clamps cannot be installed in narrow spaces;

[0020] The tubing loading and unloading rod combines an installation groove and a disassembly ramp, utilizing the lever principle and fulcrum support to significantly reduce the intensity of manual operation and improve loading and unloading efficiency. Furthermore, this structural design is adaptable to both installation and disassembly conditions, and the pad support avoids operational deviations and reduces the risk of tubing damage.

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Please see Figure 1-5As shown, a machine tool linear guide lubrication oil pipe mounting and dismounting structure includes a large-stroke worktable 3 slidably mounted on the bed 1. The bottom of the worktable 3 distributes lubrication oil pipes 2 to each slider of the linear guide through connecting pipe fittings, providing lubrication oil to the linear guide and slider. The lubrication oil pipes 2 located at both ends and the outer side of the bed 1 are directly fixed with standard pipe clamps, while the lubrication oil pipes 2 located inside the bed 1 cannot be fixed with standard pipe clamps. Therefore, the lubrication oil pipes 2 at this location are fixed with oil pipe fixing components 5.

[0033] The oil pipe fixing assembly 5 includes a fixing plate 501 fixed to the bottom surface of the workbench 3 by screws. A movable plate 502 is provided on one side of the fixing plate 501. A circular groove is provided on one side of the fixing plate 501. A circular protrusion is provided on the opposite side of the movable plate 502 and the fixing plate 501. The circular protrusion and the circular groove are installed together, so that the movable plate 502 can rotate around the joint surface of the two at a certain angle.

[0034] A spring 504 is provided between the movable plate 502 and the fixed plate 501, and a stud 503 is provided through both of them. The spring 504 is sleeved on the outside of the stud 503, and the two ends of the spring 504 abut against the upper part of the movable plate 502 and the fixed plate 501 respectively. The end of the stud 503 that passes through the movable plate 502 is tightened by a nut 505 to prevent the stud 503 from coming out and to keep the spring 504 with a certain initial elastic force.

[0035] The lower parts of the movable plate 502 and the fixed plate 501 are provided with inclined surfaces that are far apart from each other, and semi-circular grooves are provided at the root of the inclined surfaces to form a circular clamping groove 506.

[0036] A pad 22 is fixed on the bed 1 at the corresponding position below the oil pipe fixing assembly 5 to support the oil pipe loading and unloading rod 6. This allows the rod to be moved to align with the oil pipe when loading and unloading the lubricating oil pipe 2, making the loading and unloading operation easier and more feasible.

[0037] Furthermore, one end of the tubing loading / unloading rod 6 is provided with an installation groove 601, and the other end is provided with a disassembly ramp 602.

[0038] like Figure 6 As shown, when using the oil pipe loading / unloading rod 6 to install the lubricating oil pipe 2:

[0039] The lubricating oil pipe 2 is confined within the mounting groove 601 of the oil pipe loading and unloading rod 6. The oil pipe loading and unloading rod 6 is moved to adjust the left and right position of the lubricating oil pipe 2, so that the lubricating oil pipe 2 is aligned with the oil pipe fixing assembly 5. Using the linear guide rail on the outside of the bed 1 as the fulcrum, the lever principle is used to lift the oil pipe loading and unloading rod 6, applying an upward supporting force to the lubricating oil pipe 2, causing the lubricating oil pipe 2 to move upward. When the lubricating oil pipe 2 contacts the movable plate 502, the movable plate 502 is subjected to pressure, which squeezes the spring 504 and causes it to rotate, opening the clamping groove 506. The lubricating oil pipe 2 is then inserted into the clamping groove 506. At this time, the oil pipe loading and unloading rod 6 is withdrawn, and the spring 504 applies a force to the movable plate 502 to reset it and clamp the lubricating oil pipe 2, thus completing the function of clamping the lubricating oil pipe 2.

[0040] like Figure 7 As shown, when using the oil pipe loading / unloading lever 6 to disassemble the lubricating oil pipe 2:

[0041] The disassembly ramp 602 of the oil pipe loading and unloading rod 6 is inserted into the gap between the bottom surface of the workbench 3 and the lubricating oil pipe 2. The disassembly ramp 602 contacts the lubricating oil pipe 2. Using the bottom surface of the workbench 3 as a fulcrum, a downward pressure is applied to the lubricating oil pipe 2. Under the pressure, the lubricating oil pipe 2 moves downward. At this time, the movable plate 502 compresses the spring 504 and rotates, causing the clamping groove 506 of the oil pipe fixing assembly 5 to open. The lubricating oil pipe 2 is moved out of the clamping groove 506, and the movable plate 502 returns to its original position, completing the removal of the lubricating oil pipe.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
