Description

Technical Field

[0001] The utility model relates to the field of guide rail lubrication for numerically controlled machine tools, in particular to a guide rail lubrication device for numerically controlled machine tools. Background Art

[0002] CNC lathes use computer control to achieve corresponding movements of the machine tool. In the field of processing and manufacturing, CNC machine tools have been widely used to process corresponding devices. The guide rails in the machine tools are the core components in the field of transmission elements. They are mainly used to support and guide the moving parts to move in a certain direction. In order to reduce the friction between the guide rails and the sliders and prevent water vapor in the air from corroding the metal, lubricating oil is generally added to the sliders regularly to lubricate the ball bearings inside them.

[0003] The current lubrication structure for CNC machine tool guide rails still has certain shortcomings during use: first, scrapers made of elastic materials are generally installed on both sides of the guide rail slider to prevent external metal debris from entering the guide rail. However, the current use of a single scraper for protection is not only inconvenient to install, but also has a poor blocking effect, which makes it easy for powder and other objects to enter the guide rail, causing the internal ball bearing and the guide rail and slider to increase the friction. Secondly, the gap between the screw and the machine tool base in some machine tools is small, and the connection between the nut and the workbench is located on the lower side of the workbench, resulting in the grease gun being unable to connect to the nut's oil filling hole, so that workers need to manually brush oil on the screw at regular intervals, which is inconvenient.

[0004] Therefore, it is necessary to provide a new CNC machine tool guide rail lubrication device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a guide rail lubrication device for a numerically controlled machine tool, which has good guide rail protection effect, is convenient for disassembling and assembling scrapers and has a convenient-to-use screw rod lubrication component.

[0006] In order to solve the above technical problems, the utility model provides a CNC machine tool guide rail lubrication device comprising: a magnet, the bottom of the magnet is fixedly connected to a first oil storage box through a connecting rod, the inner surface of the first oil storage box is provided with oil brushing cotton, a second cleaning module is provided at a position on one side of the first oil storage box, a first nozzle is symmetrically installed on a side surface of the second cleaning module away from the first oil storage box, two second cleaning modules are symmetrically arranged up and down, the first cleaning modules are arranged at positions on the left and right sides of the second cleaning module, the second nozzle is symmetrically arranged on the surface of the first cleaning module, a connecting pipe is connected between the two second cleaning modules, an air intake pipe is connected between the connecting pipe and the first cleaning module, and the air intake pipe can be connected to an external fan, a side block is provided at a position on one side of the first cleaning module, the surface of the side block is symmetrically provided with mounting grooves, a scraper is provided inside the mounting groove, and protrusions are provided on the inner edge positions of the left and right sides of the scraper surface, and the protrusions are located on the inner side of the mounting groove.

[0007] As a further solution of the utility model, a base is provided at the lower side of the first oil storage box, guide rails are installed on both sides of the top of the base by bolts, a plurality of evenly distributed mounting holes are opened on the surface of the guide rails, a slider is slidably connected to the surface of the guide rails, and a workbench is connected between the plurality of sliders.

[0008] Through the above technical solution, the slider slides on the guide rail through the ball bearings, and the second oil storage boxes on both sides of the slider apply lubricating oil to the ball bearings, so that the friction between the ball bearings and the slider and the guide rail is reduced, thereby improving the life of the structure.

[0009] As a further solution of the utility model, a motor seat and a tail end seat are respectively installed on the surface of the base located between the two guide rails, a screw rod is arranged between the motor seat and the tail end seat, the surface of the screw rod is connected to the bottom of the workbench through a nut, the oil brush cotton is in contact with the surface of the screw rod, and the two second cleaning modules are respectively located on the upper and lower sides of the screw rod.

[0010] Through the above technical scheme, the screw is connected to the workbench through a nut, driving the workbench to translate along the guide rail. In order to avoid the problem that the gap between the screw and the machine tool base in some machine tools is small, resulting in the oiling gun being unable to connect to the oiling hole of the nut, so that the workers need to manually brush oil on the screw at regular intervals, a first oil storage box is designed. The user first fixes the magnet at a suitable position on the bottom of the workbench so that the oil brushing cotton can contact the surface of the screw, and then injects oil into the interior through the oil inlet. In this way, when the nut drives the workbench to slide on the screw, the nut will pass through the place where the oil brushing cotton has brushed oil, and the lubricating oil will be evenly applied to the screw and the nut ball surface to complete the automatic lubrication work. In order to prevent the powder and debris generated by cutting from affecting the operation between the nut and the screw in the subsequent processing process, a detachable second cleaning module is set in the structure. When in use, the fan is turned on to supply air to several first nozzles to achieve the cleaning effect on the surface of the screw.

[0011] As a further solution of the utility model, a collection box is provided on the upper side of the base, and ear plates are welded symmetrically on the left and right side walls of the collection box. The internal threads of the ear plates are connected with fastening bolts, and the two groups of fastening bolts on the left and right sides are respectively abutted against the surfaces of the motor seat and the tail end seat.

[0012] Through the above technical solution, when oil drips from the surface of the screw during operation, or when oil leakage is caused by other reasons, since the structure provides a collection box with an open top on the base, this part of the waste oil can be collected to avoid contaminating the base and making it inconvenient to clean up later.

[0013] As a further solution of the utility model, a second oil storage box is provided on both left and right sides of the plurality of sliding blocks, the second oil storage box is connected to the side block by bolts, and the first cleaning module is bonded to the side block.

[0014] Through the above technical scheme, scrapers made of elastic materials are generally installed on both sides of the traditional guide rail slider to prevent external metal debris and the like from entering the guide rail. However, the current use of a single scraper for protection is not only inconvenient to install, but also has a poor blocking effect, which makes it easy for powder and the like to enter the guide rail, causing the internal ball bearing and the guide rail and the slider to increase the friction. The structure is provided with a special side block on one side of the slider. The user first presses the scraper into the installation groove. At this time, the protrusions on both sides of the scraper will automatically buckle at the edge of the installation groove to complete the fixation. The structure makes it very convenient to install and replace the scraper later, and the design of the two sets of scrapers can largely prevent powder from entering the slider and extend the service life of the sealing assembly. At the same time, in order to prevent metal debris and powder from continuously contacting the scraper, the structure is also provided with a first cleaning module on one side of the side block to blow away impurities on the guide rail, and the structural design is reasonable.

[0015] As a further solution of the present invention, two card slots are provided at positions close to each other on the side wall surfaces of the two second cleaning modules, and a card member is connected between the two card slots distributed vertically.

[0016] Through the above technical solution, the upper and lower second cleaning modules are connected together by a clamp, and when they need to be disassembled, it is only necessary to remove the clamp.

[0017] As a further solution of the utility model, the magnet is connected to the bottom of the workbench, and the surfaces of the first oil storage box and the second oil storage box are both provided with oil inlets, and rubber plugs are provided inside the oil inlets.

[0018] Through the above technical solution, lubricating oil can be injected into the first oil storage box and the second oil storage box through the oil inlet, and the user can add lubricating oil regularly according to the frequency of use of the machine tool.

[0019] Compared with the related art, the CNC machine tool guide rail lubrication device provided by the utility model has the following beneficial effects:

[0020] 1. In the utility model, scrapers made of elastic materials are generally installed on both sides of the conventional guide rail slider to prevent external metal debris and the like from entering the guide rail. However, the current use of a single scraper for protection is inconvenient to install and has a poor blocking effect, which makes it easy for objects such as powder to enter the guide rail, causing the friction between the internal ball bearing and the guide rail and the slider to increase. The structure is provided with a special side block at one side of the slider. The user first presses the scraper into the installation groove. At this time, the protrusions on both sides of the scraper will automatically buckle at the edge of the installation groove to complete the fixation. The structure makes it very convenient to install and replace the scraper later, and the design of the two sets of scrapers can largely prevent powder from entering the slider and extend the service life of the sealing assembly. At the same time, in order to prevent metal debris and powder from continuously contacting the scraper, the structure is also provided with a first cleaning module on one side of the side block to blow away impurities on the guide rail, and the structural design is reasonable.

In this way, when the nut drives the workbench to slide on the screw, the nut will evenly apply the lubricating oil to the surface of the screw and the nut ball bearing where it has been brushed with oil by the oil brushing cotton, completing the automatic lubrication work. In order to prevent the powder and debris generated by cutting from affecting the operation between the nut and the screw in the subsequent processing process, a detachable second cleaning module is set in this structure. When in use, the fan is turned on to supply air to the first nozzles to achieve the cleaning effect on the surface of the screw. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The screw rod 8 is connected to the workbench 5 through a nut, driving the workbench 5 to translate along the guide rail 2.

[0039] Elastic scrapers 21 are generally installed on both sides of the slider 6 of the traditional guide rail 2 to prevent external metal debris and the like from entering the guide rail 2. However, the current use of a single scraper 21 for protection is not only inconvenient to install, but also has a poor blocking effect, which makes it easy for powder and the like to enter the guide rail 2, causing the friction between the internal ball and the guide rail 2 and the slider 6 to increase. The structure is provided with a special side block 20 at one side of the slider 6. The user first presses the scraper 21 into the installation groove 23. At this time, the protrusions 22 on both sides of the scraper 21 will automatically buckle at the edge of the installation groove 23 to complete the fixation. The structure makes it very convenient to install and replace the scraper 21 later, and the design of the two sets of scrapers 21 can largely prevent powder from entering the slider 6 and extend the service life of the sealing assembly. At the same time, in order to prevent metal debris and powder from continuously contacting the scraper 21, the structure is also provided with a first cleaning module 7 on one side of the side block 20 to blow away impurities on the guide rail 2, and the structural design is reasonable.

[0044] The working principle of a CNC machine tool guide rail lubrication device provided by the utility model is as follows:

[0045] Step 1: On both sides of the slider 6 of the conventional guide rail 2, scrapers 21 made of elastic material are generally installed to prevent external metal debris and the like from entering the guide rail 2. However, the current use of a single scraper 21 for protection is not only inconvenient to install, but also has a poor blocking effect, which makes it easy for objects such as powder to enter the guide rail 2, causing the friction between the internal ball and the guide rail 2 and the slider 6 to increase. The structure is provided with a special side block 20 at one side of the slider 6. The user first presses the scraper 21 into the installation groove 23. At this time, the protrusions 22 on both sides of the scraper 21 will automatically buckle at the edge of the installation groove 23 to complete the fixation. The structure makes it very convenient to install and replace the scraper 21 later, and the design of the two sets of scrapers 21 can largely prevent powder from entering the slider 6 and extend the service life of the sealing component. At the same time, in order to prevent metal debris and powder from continuously contacting the scraper 21, the structure is also provided with a first cleaning module 7 on one side of the side block 20 to blow away the impurities on the guide rail 2. The structural design is reasonable.

[0046] The second step: In order to avoid the problem that the gap between the screw 8 and the machine tool base 1 in some machine tools is too small, resulting in the oiling gun being unable to connect to the oiling hole of the nut, so that the workers need to manually brush oil on the screw 8 at regular intervals, the device is designed with a first oil storage box 14. The user first fixes the magnet 13 at a suitable position on the bottom of the workbench 5 so that the oil brushing cotton 15 can contact the surface of the screw 8, and then injects oil into the interior through the oil inlet 27. In this way, when the nut drives the workbench 5 to slide on the screw 8, the nut will pass through the place where the oil brushing cotton 15 has brushed oil, and the lubricating oil will be evenly applied to the screw 8 and the nut ball surface to complete the automatic lubrication work. In order to prevent the powder and debris generated by cutting from affecting the operation between the nut and the screw 8 in the subsequent processing process, the structure is provided with a detachable second cleaning module 19. When in use, the fan is turned on to supply air to the first nozzles 16 to achieve the cleaning effect on the surface of the screw 8.
