Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to an oil injection device for lubricating CNC machine tool components. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. CNC machine tools effectively solve the problems of machining complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product. Machine tools are one of the most commonly used pieces of equipment in current machining. During the use of machine tools, guideways play a very important role. Once the machine tool guideways wear, it affects machining accuracy. To reduce wear caused by guideway operation, lubricating oil is generally added to the guideways.

[0003] Existing devices cannot clean the guide rails before adding oil. Dust and raw material debris can easily mix with the lubricating oil to form a gel-like substance, which can lead to accuracy errors in the guide rails and reduce their service life. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides: an oil injection device for lubricating CNC machine tool parts, including a movable bracket having a plate-like structure, and a device housing disposed on the movable bracket, wherein the outer side of the device housing is fixedly connected to the movable bracket;

[0005] A rolling wheel for moving a movable support, and a base disposed outside the rolling wheel, with a hydraulic cylinder mounted on the top of the base;

[0006] A liquid storage tank for storing lubricating oil, and a liquid filling pipe disposed at the top of the liquid storage tank, the liquid filling pipe being connected to the liquid storage tank;

[0007] A pretreatment device is provided for cleaning dust inside the guide rail. The pretreatment device is located inside the housing of the device and includes a blower pipe for blowing air into the inside of the guide rail.

[0008] Preferably, the bottom of the device housing is open, both ends of the movable bracket penetrate the device housing, and the movable end of the hydraulic cylinder is fixedly connected to the end of the movable bracket.

[0009] Preferably, the end of the liquid filling tube away from the liquid storage cylinder passes through and extends to the outside of the device housing, and the liquid filling tube is fixedly connected to the device housing.

[0010] Preferably, the pretreatment device is located below the movable support, the liquid storage cylinder is located on top of the movable support, and the liquid storage cylinder is located inside the outer shell of the device.

[0011] Preferably, the pretreatment device further includes a fixed cylinder, the outer side of which is rotatably connected to an annular rolling pad via a rolling bearing. An air inlet pipe runs through the inside of the fixed cylinder, the bottom of which is connected to a blowing pipe, and a liquid inlet pipe is connected to the top of the fixed cylinder. A lubrication and oiling device is installed inside the fixed cylinder. The movable support is placed above the guide rail of the CNC machine tool, and the pretreatment device is lowered to a position close to the inside of the guide rail by means of a hydraulic cylinder. At the same time, one end of the air inlet pipe is connected to an external air extraction device, and the external air extraction device draws gas into the air inlet pipe. The gas entering the air inlet pipe is then blown into the inside of the guide rail through the blowing pipe, blowing away dust and raw material waste. This allows the guide rail to be cleaned before oiling, preventing dust, raw material waste, and lubricating oil from mixing and forming a gel-like substance, avoiding precision errors in the guide rail, and improving the service life of the guide rail.

[0012] Preferably, the fixing cylinder is disposed inside the outer shell of the device, the fixing cylinder is located at the bottom of the movable support, the annular rolling pad is sleeved on the outside of the fixing cylinder, and two sets of the annular rolling pad are provided and symmetrically distributed at both ends of the outside of the fixing cylinder.

[0013] Preferably, the end of the blower pipe away from the air inlet pipe passes through and extends to the outside of the fixed cylinder, the blower pipe is fixedly connected to the fixed cylinder, the end of the air inlet pipe away from the blower pipe passes through and extends to the outside of the fixed cylinder, and the top of the liquid inlet pipe passes through the movable bracket and communicates with the liquid storage cylinder.

[0014] Preferably, the lubrication and oiling device includes a connecting pipe with inlets evenly distributed on its exterior. Extension pipes connect to both ends of the connecting pipe, and a fixed sleeve is fitted and fixedly connected to the outer side of each extension pipe. A limiting bracket is installed on the inner wall of the extension pipe away from the connecting pipe, and an oil draining device is installed on the side of the limiting bracket away from the connecting pipe. A rolling wheel drives the pretreatment device to move along the guide rail via a moving bracket. At this time, the lubricating oil inside the reservoir enters the fixed cylinder through the inlet pipe and then drains into the connecting pipe through the inlet. The connecting pipe drains the lubricating oil through the extension pipe and the oil draining device, thus adding lubricating oil to the inside of the guide rail. When the fixed cylinder moves along the inner wall of the guide rail, the sliding friction can be changed to rolling friction by a ring-shaped rolling pad, reducing the friction between the fixed cylinder and the inner wall of the guide rail and preventing friction damage to the machine tool guide rail.

[0015] Preferably, both ends of the connecting tube pass through the fixed cylinder and are fixedly connected to the fixed cylinder, and the outer side of the fixed sleeve is fixedly connected to the bottom of the device housing.

[0016] Preferably, the oil draining device further includes an oil drain pipe, an annular sleeve, and a sealing plug. One end of the oil drain pipe is connected to a compression ball shell. Both the compression ball shell and the outer side of the oil drain pipe have oil drain ports. An annular sliding plate is fitted onto the end of the oil drain pipe away from the compression ball shell. The outer side of the annular sliding plate is slidably connected to the inner wall of the extension pipe. The inner wall of the guide rail contacts and compresses the compression ball shell, forcing it into the extension pipe. At this time, both sets of compression ball shells can slide into the extension pipe, which can adapt to guide rails of different widths. Oil filling can also be completed for guide rails with smaller widths, improving the adaptability of the device. The annular sleeve is fitted onto the outer side of the extension pipe. The inner wall of the annular sleeve is connected to a compression head by a spring. An arc-shaped opening is opened on the inner wall of the extension pipe near the compression head. The oil drain pipe is close to the annular sleeve. One end of the sliding plate extends into the extension tube and is fixedly connected to an annular sealing ring. One end of the sealing plug is fixedly connected to the limiting bracket via a fixing rod. The end of the sealing plug away from the limiting bracket extends into the annular sealing ring. The hydraulic cylinder drives the pretreatment device to descend into the guide rail via the moving bracket. The inner wall of the guide rail touches the extrusion ball shell and extrudes it, pushing the extrusion ball shell into the extension tube. The extrusion ball shell slides along the inner wall of the extension tube via the annular sliding plate. As the extrusion ball shell slides into the extension tube, the annular sealing ring is removed from the sealing plug. The sealing plug no longer blocks the annular sealing ring. At this time, the lubricating oil in the extension tube enters the oil drain pipe from the annular sealing ring and then injects oil into the inner wall of the guide rail through the oil drain port, thus completing the purpose of automatic oil injection and improving the automation level of the device.

[0017] This invention provides an oil injection device for lubricating CNC machine tool parts. It has the following beneficial effects:

[0018] 1. This is an oil injection device for lubricating CNC machine tool parts. Through the installation of a pre-treatment device, a movable support is placed above the guide rail of the CNC machine tool. A hydraulic cylinder uses the movable support to lower the pre-treatment device to a position close to the inside of the guide rail. Simultaneously, one end of the air inlet pipe is connected to an external air extraction device. The external air extraction device draws gas into the air inlet pipe, and the gas entering the air inlet pipe is then blown into the inside of the guide rail through the air blower, blowing away dust and material debris. This allows the guide rail to be cleaned before oiling, preventing dust, material debris, and lubricating oil from mixing and forming a gel-like substance, avoiding precision errors in the guide rail, and improving the service life of the guide rail.

[0019] 2. This is an oil injection device for lubricating CNC machine tool parts. Through the installation of a lubrication oil filling device and a pretreatment device, the rolling wheel drives the pretreatment device to move along the guide rail via a moving bracket. At this time, the lubricating oil inside the reservoir enters the fixed cylinder from the inlet pipe, and then is discharged into the connecting pipe through the inlet. The connecting pipe discharges the lubricating oil through the extension pipe and the oil discharge device, thus adding lubricating oil to the inside of the guide rail. When the fixed cylinder moves along the inner wall of the guide rail, the sliding friction can be changed to rolling friction through the annular rolling pad, reducing the friction between the fixed cylinder and the inner wall of the guide rail and avoiding friction damage to the machine tool guide rail.

[0020] 3. This is an oil injection device for lubricating CNC machine tool parts. Through the installation of an oil discharge device and a pretreatment device, the hydraulic cylinder drives the pretreatment device to descend into the guide rail via a moving bracket. The inner wall of the guide rail contacts and squeezes the extrusion ball shell, pushing the extrusion ball shell into the extension tube. The extrusion ball shell slides along the inner wall of the extension tube via an annular sliding plate. As the extrusion ball shell continues to slide into the extension tube, the annular sealing ring moves away from the sealing plug, and the sealing plug no longer blocks the annular sealing ring. At this time, the lubricating oil in the extension tube enters the oil discharge pipe from the annular sealing ring, and then injects oil into the inner wall of the guide rail through the oil discharge port, thus completing the purpose of automatic oil injection and improving the automation level of the device.

[0021] 4. This is an oil injection device for lubricating CNC machine tool parts. By installing the extrusion ball shell and the oil discharge pipe, the inner wall of the guide rail contacts the extrusion ball shell and squeezes it, squeezing the extrusion ball shell into the extension tube. At this time, both sets of extrusion ball shells can slide into the extension tube, which can adapt to guide rails of different widths. It can also complete the oil injection for guide rails with smaller widths, thus improving the adaptability of the device. Attached Figure Description

[0040] The pretreatment device 8 also includes a fixed cylinder 82. An annular rolling pad 83 is rotatably connected to the outside of the fixed cylinder 82 via a rolling bearing. An air inlet pipe 84 passes through the inside of the fixed cylinder 82. The bottom of the air inlet pipe 84 is connected to the air blowing pipe 81. An liquid inlet pipe 85 is connected to the top of the fixed cylinder 82. A lubrication and oiling device 86 is provided inside the fixed cylinder 82.

[0041] The fixed cylinder 82 is located inside the outer casing 2 of the device and is located at the bottom of the movable support 1. The annular rolling pad 83 is sleeved on the outside of the fixed cylinder 82. Two sets of the annular rolling pad 83 are provided and symmetrically distributed at both ends of the outside of the fixed cylinder 82.

[0042] The end of the blower pipe 81 away from the air inlet pipe 84 passes through and extends to the outside of the fixed cylinder 82. The blower pipe 81 is fixedly connected to the fixed cylinder 82. The end of the air inlet pipe 84 away from the blower pipe 81 passes through and extends to the outside of the fixed cylinder 82. The top of the liquid inlet pipe 85 passes through the movable bracket 1 and is connected to the liquid storage cylinder 6.

[0043] The lubrication and oiling device 86 includes a connecting pipe 861, with inlets 862 evenly distributed on the outside of the connecting pipe 861.

A limit bracket 865 is installed on the end of the inner wall of the extension pipe 863 away from the connecting pipe 861. An oil discharge device 866 is installed on the side of the limit bracket 865 away from the connecting pipe 861.

[0044] Both ends of the connecting pipe 861 pass through the fixed cylinder 82 and are fixedly connected to the fixed cylinder 82. The outer side of the fixed sleeve 864 is fixedly connected to the bottom of the device housing 2.

[0045] In use, the movable support 1 is placed above the guide rail of the CNC machine tool. The hydraulic cylinder 5 uses the movable support 1 to drive the pretreatment device 8 to a position close to the inside of the guide rail. At the same time, one end of the air inlet pipe 84 is connected to the external air extraction equipment. The external air extraction equipment draws gas into the air inlet pipe 84. The gas entering the air inlet pipe 84 is then blown into the inside of the guide rail through the air blowing pipe 81, blowing away dust and raw material waste. This allows the guide rail to be cleaned before adding oil, preventing dust, raw material waste and lubricating oil from mixing and forming a gel-like substance, avoiding precision errors in the guide rail and improving the service life of the guide rail.

[0046] The rolling wheel 3 drives the pretreatment device 8 to move along the guide rail via the movable bracket 1. At this time, the lubricating oil inside the reservoir 6 enters the fixed cylinder 82 through the inlet pipe 85, and then is discharged into the connecting pipe 861 through the inlet port 862. The connecting pipe 861 discharges the lubricating oil through the extension pipe 863 and the oil discharge device 866, thus adding lubricating oil to the inside of the guide rail. When the fixed cylinder 82 moves along the inner wall of the guide rail, the sliding friction can be changed to rolling friction through the annular rolling pad 83, reducing the friction between the fixed cylinder 82 and the inner wall of the guide rail and avoiding friction damage to the machine tool guide rail.

[0047] Please see Figures 1-9 The present invention provides a technical solution: Based on Embodiment 1, the oil discharge device 866 further includes an oil discharge pipe 8661, an annular sleeve 8665, and a sealing plug 8669. One end of the oil discharge pipe 8661 is connected to a compression ball shell 8662. Both the compression ball shell 8662 and the outer side of the oil discharge pipe 8661 are provided with oil discharge ports 8663. An annular sliding plate 8664 is fitted onto the end of the oil discharge pipe 8661 away from the compression ball shell 8662.

Located on the outside of the extension tube 863, the inner wall of the annular sleeve 8665 is connected to the extrusion head 8666 by a spring. An arc-shaped opening 8667 is opened on the inner wall of the extension tube 863 near the extrusion head 8666.

The inner wall of the guide rail contacts and squeezes the extrusion ball shell 8662, pushing the extrusion ball shell 8662 into the extension tube 863. The extrusion ball shell 8662 slides along the inner wall of the extension tube 863 via the annular slide plate 8664. As the extrusion ball shell 8662 continues to slide into the extension tube 863, the annular sealing ring 8668 is removed from the sealing plug 8669. The sealing plug 8669 no longer blocks the annular sealing ring 8668. At this time, the lubricating oil in the extension tube 863 enters the oil drain pipe 8661 from the annular sealing ring 8668, and then injects oil into the inner wall of the guide rail through the oil drain port 8663, thus completing the purpose of automatic oil injection and improving the automation level of the device.
