Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool guideway lubrication technology, and in particular to a CNC machine tool guideway lubrication device. Background Technology

[0002] CNC machine tool guideways are an important component of CNC machine tools. They serve as the guiding tracks for the movement of various machine tool parts, guiding them to move along a specified trajectory and speed. They also bear and distribute the weight and cutting forces of the moving parts, ensuring the machining accuracy and stability of the machine tool. After a period of use, the guideways require lubrication of their internal grooves using the CNC machine tool guideway lubrication device.

[0003] A search revealed Chinese Patent Publication No. CN221363675U, which discloses a CNC machine tool guideway lubrication device. The device includes a machine tool guideway body with a mounting base snapped onto its top. Multiple guideway grooves are formed on the top of the machine tool guideway body. In use, this structure is driven by a motor. However, due to friction between the mounting base and the top of the machine tool guideway body, and the connection plate via springs and telescopic rods, the rollers are prone to slippage during movement, potentially leading to device malfunction. Furthermore, the device uses an oil injection pipe for lubrication, but the lubricating oil drips linearly due to gravity, resulting in uneven lubrication and poor lubrication performance, requiring subsequent application. Therefore, this paper proposes a CNC machine tool guideway lubrication device to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a CNC machine tool guideway lubrication device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A CNC machine tool guideway lubrication device includes a machine tool guideway body, a guideway groove on the top of the machine tool guideway body, a support frame above the machine tool guideway body, an electric push rod on the top of the support frame, a mounting plate on the output end of the electric push rod, a lubricating oil tank fixedly mounted on the top of the mounting plate, mounting holes inside the mounting plate, drive mechanisms extending to and fitting against the sides of the machine tool guideway body on both sides of the support frame, an oil delivery assembly penetrating the mounting holes and extending into the inner side of the support frame on the top of the mounting plate, and a lubrication auxiliary assembly at the bottom of the oil delivery assembly. The drive mechanism includes two mounting frames, which are fixedly mounted on both sides of the support frame. A first screw extending to the outside of the mounting frame is rotatably mounted inside the mounting frame. An extension block extending to the bottom of the mounting frame is threaded onto the outside of the first screw. A drive motor is fixedly mounted at the bottom of the extension block. The output shaft of the drive motor passes through the inside of the extension block and is fixedly connected to a roller that fits against the outside of the machine tool guide rail body.

[0006] Preferably, two support wheels are rotatably installed on both the left and right sides inside the support frame and are attached to the top of the machine tool guide rail body, and dustproof brushes are fixedly installed on both the left and right sides of the support frame.

[0007] Preferably, the oil delivery assembly includes a sliding block, which is slidably installed inside the mounting hole. A second screw extending to the top of the mounting plate is rotatably installed on the top of the sliding block. A pressure plate that fits against the top of the mounting plate is threaded onto the outer side of the second screw. An oil delivery pipe penetrating to the inner side of the support frame is fixedly connected to the bottom of the sliding block. A sponge frame is fixedly connected to the bottom of the oil delivery pipe.

[0008] Preferably, the lubrication auxiliary component includes a lubricating sponge, which is movably installed inside a sponge frame and extends to its outer side. A third screw extending to its outer side is threaded inside the sponge frame. A clamping plate that fits against the lubricating sponge is rotatably installed at one end of the third screw located inside the sponge frame. A cleaning brush is threadedly installed on the left side of the sponge frame via bolts.

[0009] Preferably, the mounting frame has openings on both the top and bottom sides, and a rotating block is fixedly connected to the end of the first screw located on the outside of the mounting frame.

[0010] Preferably, the inner bottom wall of the lubricating oil tank is connected to a flexible hose that is connected to the oil delivery pipe.

[0011] Preferably, a knob is fixedly connected to one end of the third screw located outside the sponge frame, and the bottom of the oil delivery pipe is connected to the interior of the sponge frame and located above the lubricating sponge.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This CNC machine tool guideway lubrication device uses a drive mechanism with two symmetrically arranged first screws and extension blocks in the drive frame. The drive motor drives the rollers to roll against the outer side of the machine tool guideway body. Combined with the support wheel at the bottom of the support frame and the top of the guideway, a double support structure is formed. This design transforms traditional sliding friction into rolling friction, reducing frictional resistance. Furthermore, the first screw can be manually adjusted by rotating the extension block to effectively adapt to the size of the CNC machine tool guideway, solving the problem of movement failure caused by frictional resistance in existing technologies.

[0013] This CNC machine tool guideway lubrication device uses a sliding block of the oil delivery component to form a vertical adjustment mechanism with a second screw and a pressure plate. This, combined with a clamping plate driven by a third screw in the lubrication auxiliary component, elastically pre-tightens the lubricating sponge. When lubricating oil is delivered to the oil delivery pipe via a hose, the lubricating sponge in the sponge frame absorbs the oil, forming a uniform oil outlet cross-section during guideway lubrication. Combined with the pre-cleaning effect of the cleaning brush on the guideway surface, effective lubrication of the guideway is achieved, significantly improving the lubrication effect and efficiency of the device.

In conjunction with the clamping plate 93 driven by the third screw 92 in the lubrication auxiliary component 9, the lubricating sponge 91 is elastically pre-tightened. When the lubricating oil is delivered to the oil supply pipe 84 through the hose 841, the lubricating sponge 91 in the sponge frame 85 absorbs the lubricating oil, forming a uniform oil outlet cross section during guide rail lubrication, realizing effective lubrication of the guide rail, and effectively improving the lubrication effect and efficiency of the device.

[0024] The working process of this utility model: Step 1: By controlling the start drive motor 74, the roller 75 is driven to roll along the outside of the guide rail, and the contact between the support wheel 31 and the top of the guide rail maintains the horizontal displacement stability of the device. Step 2: During adjustment, the sliding block 81 adjusts the height of the pressure plate 83 by rotating the second screw 82, so that the position of the sliding block 81 can be adjusted according to the position of the guide rail groove 2; Step 3: By controlling the start of the electric push rod 4, the mounting plate 5 is driven to descend, so that the lubricating sponge 91 at the bottom of the oil supply pipe 84 contacts the guide rail surface. Lubricating oil flows from the lubricating oil tank 6 into the oil supply pipe 84 through the hose 841. After being absorbed by the lubricating sponge 91, the lubricating oil is evenly spread onto the guide rail surface. At the same time, the cleaning brush 94 removes impurities from the guide rail surface to improve the lubrication effect. When maintenance is required, the third screw 92 is rotated to loosen the clamping plate 93 from the lubricating sponge 91, and the sponge module can be quickly replaced.
