Description

Technical Field

[0001] This application relates to the technical field of CNC machine tools, and in particular to an oil receiving device for CNC machine tools. Background Technology

[0002] CNC machine tools, short for Computer Numerical Control machine tools, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] The headstock of existing CNC machine tools needs to drive the cutting tool to process different positions of the workpiece. To reduce wear on the headstock during vertical operation and to lower the risk of jamming between the slider and its linear guide in the headstock module, lubricating oil needs to be applied regularly to the slider and linear guide in the headstock module during CNC machine tool use. This ensures smooth movement of the CNC machine tool headstock and extends its service life. However, the use of lubricating oil generates waste oil, which flows downwards onto the workpiece being processed due to its own gravity, affecting the processing quality. Waste oil also flows onto the CNC milling machine's worktable, increasing the difficulty of cleaning the worktable.

[0004] Regarding the aforementioned technologies, the inventors believe that there are drawbacks, such as the waste oil generated by the lubricating oil on the slide and guide rail of the CNC machine tool after operation flowing downwards onto the workpiece being processed, affecting the workpiece processing quality, and the waste oil also flowing onto the worktable of the CNC milling machine, increasing the difficulty for the staff to clean the worktable. Utility Model Content

[0005] To address the issue of waste oil generated by the lubricating oil on the slider and guide rail in the head module of a CNC machine tool flowing downwards onto the workpiece being machined after operation, affecting the workpiece's machining quality, and also flowing onto the worktable of the CNC milling machine, increasing the difficulty for operators to clean the worktable, this application provides an oil receiving device for CNC machine tools.

[0006] This application provides an oil receiving device for CNC machine tools, which adopts the following technical solution:

[0007] An oil receiving device for a CNC machine tool includes a base plate installed at the bottom of the machine head module of the CNC machine tool. An oil receiving box is slidably disposed on the base plate. The oil receiving box is located below the guide rail on the machine head module. An opening for collecting waste oil on the guide rail is provided at the top of the oil receiving box. The guide rail is located above the opening. The length of the opening is greater than the distance between the guide rails, and the width of the opening is greater than the thickness of the guide rail. A filter module is installed inside the oil receiving box, and an oil outlet is provided at the bottom of the oil receiving box.

[0008] By adopting the above technical solution, the substrate provides the mounting base for the oil receiving box. The substrate is installed below the machine head module, and the oil receiving box is below the guide rail of the machine head module, making full use of the space of the machine head module and facilitating the direct collection of dripping waste oil. The opening on the oil receiving box can be used to directly receive waste oil on the guide rail. The length of the opening is greater than the distance between the guide rails on the machine head module. The length direction of the opening can cover two guide rails, and the width direction of the opening can cover the thickness of the guide rails. That is, the waste oil after lubrication on the guide rail can enter the oil receiving box through the opening. The filter module in the oil receiving box can filter the impurities carried by the waste oil on the guide rail. The filtered waste oil flows out through the oil outlet and can be reused. This oil receiving box device can prevent the waste oil on the guide rail from falling onto the worktable and the workpiece on the worktable due to its own weight, reducing the cleanliness of the worktable for the operator and ensuring the processing quality of the workpiece.

[0009] Optionally, the oil receiving box includes a box body and a top cover. The box body is slidably mounted on the base plate, and a handle is provided on the box body. The top cover is hinged to the box body, and the opening is formed on the top cover.

[0010] By adopting the above technical solution, the box body and the top cover hinged to the box body together constitute the oil receiving box. The hinged top cover facilitates the installation and maintenance of structures such as the filter module. The handle makes it easy to pull out the oil receiving box as a whole. The box body slides on the base plate, which facilitates the linear movement of the box body as a whole. The opening is set on the top cover, which makes it easy for the waste oil on the guide rail to drip into the box body. Moreover, the top cover can prevent the waste oil in the box body from splashing during operation.

[0011] Optionally, a slide rail is provided on the substrate, and a guide block is installed at the bottom of the box, the guide block sliding on the slide rail.

[0012] By adopting the above technical solution, the slide rail is configured to provide a sliding trajectory for the pull-out movement of the box, ensuring that the box maintains linear motion and avoiding damage to other structures of the CNC machine tool head module.

[0013] Optionally, guide plates are symmetrically arranged inside the box. The guide plates are installed obliquely inside the box. One end of the guide plate is installed on the box, and the other end is connected to the oil outlet. The end of the guide plate near the oil outlet is lower than the end of the guide plate away from the oil outlet.

[0014] By adopting the above technical solution, the guide plate is set at an angle, and the end of the guide plate near the oil outlet is lower than the end of the guide plate away from the oil outlet. The setting of the guide plate can effectively guide the dripping waste oil to flow into the oil outlet and avoid the splashing of waste liquid in the oil receiving box.

[0015] Optionally, the oil outlet is connected to an oil inlet pipe, the oil inlet pipe is connected to a filter pipe, the filter pipe contains several filter elements, the output end of the filter pipe is connected to a conveying pipe, the conveying pipe is connected to a storage box, and a ball valve is provided between the storage box and the conveying pipe.

[0016] By adopting the above technical solution, waste oil enters the bottom of the box and flows to the oil outlet after preliminary filtration by the filtration module. The waste oil from the oil outlet flows into the filter pipe by gravity. After being filtered by multiple layers of filter elements in the filter pipe, it is input into the conveying pipe. The filtered waste oil is stored in the storage tank through the conveying pipe for the next use. The ball valve facilitates the control of waste oil, making it more intelligent, convenient and fast.

[0017] Optionally, the filter module includes a first mounting block, a second mounting block, and a filter plate. The first mounting block is disposed on one side of the housing, the second mounting block is mounted on the other side of the housing, and one end of the filter plate is mounted on the first mounting block and the other end is mounted on the second mounting block.

[0018] By adopting the above technical solution, the first mounting block and the second mounting block are configured to provide an installation base for the filter plate, making it easier to place the filter plate inside the box and perform preliminary filtration of the waste oil dripping into the box.

[0019] Optionally, the first mounting block is provided with a first mounting groove, the second mounting block is provided with a second mounting groove, the filter plate is provided with a first locking member on one side and connected to a second locking member on the other side, the first locking member is disposed in the first mounting groove, and the second locking member is installed in the second mounting groove.

[0020] By adopting the above technical solution, the first mounting slot facilitates the fixed installation of one side of the filter plate on the first mounting block, and the second mounting slot facilitates the fixed installation of the other side of the filter plate on the second mounting block. The first locking member can be connected with the first mounting slot, and the second locking member can be connected with the second mounting slot. The first locking member is installed in the first mounting slot, and the second locking member is installed in the second mounting slot. This can stably install the filter plate in the box, avoiding phenomena such as falling off during the operation of the head module, and ensuring the stability of the installation.

[0021] Optionally, the installation height of the first mounting block is higher than that of the second mounting block.

[0022] By adopting the above technical solution, the filter plate can be tilted by the height difference between the first mounting block and the second mounting block. The tilted setting facilitates the flow of waste oil along the tilt direction, which can fully filter the waste oil and prevent the accumulation of waste residue that could cause the filter plate to become clogged.

[0023] Optionally, protective plates are installed on both sides of the oil receiving box. The protective plates are disposed on the base plate, and connectors are installed on the protective plates. One end of the connector is hinged to the protective plate, and the other end is connected to the oil receiving box.

[0024] By adopting the above technical solution, the protective plate can protect the head module and the oil receiving device, and also provide an installation base for the installation of the connector. The connector can connect the oil receiving box and the protective plate together. Without having to pull out the oil receiving box, the oil receiving box can be fixed on the base plate through the connector, preventing the oil receiving box from sliding out of the head module during operation.

[0025] Optionally, an accordion cover is installed on the oil receiving box, and the accordion cover is located between the two protective plates.

[0026] By adopting the above technical solution, the bellows cover can effectively block the debris and dust generated during the cutting of metal or non-metal during the processing from entering the head module, reducing its wear risk. It can form a physical barrier on the guide rail surface, reducing direct contact with external substances and effectively reducing wear caused by the external environment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By installing a base plate and an oil collection box at the bottom of the CNC machine tool head module, with the oil collection box located below the guide rails of the head module, the space of the head module is fully utilized without affecting its operation. This facilitates the direct collection of dripping waste oil. The length of the opening can cover two guide rails, and the width of the opening can cover the thickness of the guide rails. That is, the waste oil after lubrication on the guide rails can enter the oil collection box through the opening. The waste oil passes through a filter module to filter out large impurities. The filtered waste oil flows out through the oil outlet and can be reused. This device can prevent waste oil on the guide rails from falling onto the worktable and the workpieces on the worktable due to its own weight, reducing the cleanliness of the worktable for the operator and ensuring the processing quality of the workpieces.

[0029] 2. The inclined guide plate inside the oil receiving box can effectively guide the dripping waste oil to the oil outlet, and also prevent the waste liquid from splashing inside the oil receiving box;

[0030] 3. The waste oil dripping into the oil collection box flows along the inclined direction of the filter plate, which can fully filter the waste oil and prevent the waste residue from accumulating and clogging the filter plate. After the initial filtration by the filter plate, the waste oil enters the oil outlet along the guide plate. The waste oil at the oil outlet flows into the filter pipe by gravity. After being filtered by multiple filter elements in the filter pipe, it is input into the conveying pipe. The filtered waste oil is stored in the storage tank through the conveying pipe for the next use. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] This application discloses an oil receiving device for CNC machine tools, referring to... Figures 1-5The oil receiving device for CNC machine tools includes a base plate 2 installed at the bottom of the head module 1 of the CNC machine tool. An oil receiving box 3 is slidably disposed on the base plate 2. The oil receiving box 3 is located below the guide rail 11 on the head module 1. An opening 321 for collecting waste oil on the guide rail 11 is provided at the top of the oil receiving box 3. The guide rail 11 is located above the opening 321. The length of the opening 321 is greater than the distance between the guide rails 11, and the width of the opening 321 is greater than the thickness of the guide rail 11, so that it can completely accept the waste oil from the guide rail 11. A filter module 33 is installed inside the oil receiving box 3, and an oil outlet 34 is provided at the bottom of the oil receiving box 3.

[0045] The base plate 2 is directly installed below the headstock module 1 of the CNC machine tool, and the oil collection box 3 is located below the guide rail 11 of the headstock module 1. This makes full use of the space of the headstock module 1, and the installation position facilitates the direct collection of dripping waste oil. Moreover, the positions of the oil collection box 3 and the base plate 2 do not interfere with the operation of the headstock module 1. The opening 321 on the oil collection box 3 can be used to directly receive the waste oil on the guide rail 11. The length of the opening 321 is greater than the distance between the guide rails 11 on the headstock module 1. The length direction of the opening 321 can cover the two guide rails 11, and the width direction of the opening 321 can cover the thickness of the guide rails 11. That is, the waste oil or excess lubricating oil after the guide rails 11 and the sliders on the guide rails 11 are lubricated can enter the oil collection box 3 through the opening 321.

[0046] The filter module 33 inside the oil collection box 3 filters out impurities carried by the waste oil on the guide rail 11. The filtered waste oil flows out through the oil outlet 34 and can be reused. This also prevents larger impurities, such as chips from larger cutting processes, from clogging the oil outlet 34. This oil collection box 3 device prevents waste oil on the guide rail 11 from falling onto the worktable and the workpiece on the worktable due to its own weight. Waste oil dripping between the guide rail 11 and the slider falls into the oil collection box 3 below, undergoes preliminary filtration, and enters the oil outlet 34, thus collecting the waste oil, reducing the cleanliness requirements of the worktable for operators, and ensuring the processing quality of the workpiece.

[0047] refer to Figure 3 The oil receiving box 3 includes a box body 31 and a top cover 32. The box body 31 is slidably mounted on the base plate 2 and is provided with a handle 313. The top cover 32 is hinged to the box body 31 and has an opening 321. The box body 31 and the top cover 32 are separate units. The top cover 32 is hinged to the box body 31, which facilitates the installation and maintenance of internal structures such as the filter module 33. The sliding of the box body 31 on the base plate 2 facilitates the linear movement of the entire box body 31. The handle 313 of the box body 31 allows the staff to easily pull out the entire oil receiving box 3 for cleaning or maintenance. The opening 321 on the top cover 32 not only facilitates the dripping of waste oil from the guide rail 11 into the box body 31, but also prevents waste oil from splashing during operation.

[0048] A slide rail 21 is provided on the substrate 2, and a guide block 312 is installed at the bottom of the box 31. The guide block 312 slides on the slide rail 21, thereby enabling the box 31 to slide on the substrate 2. The slide rail 21 provides a sliding trajectory for the extraction and placement of the box 31, ensuring that the box 31 maintains a straight line movement. The box 31 follows the movement of the slide rail 21 to avoid deviation and damage to other structures of the CNC machine tool head module 1.

[0049] refer to Figure 4 and Figure 5 Inside the box 31, guide plates 311 are symmetrically arranged. The guide plates 311 are installed at an angle inside the box 31. One end of the guide plate 311 is installed on the box 31, and the other end is connected to the oil outlet 34. The end of the guide plate 311 near the oil outlet 34 is lower than the end of the guide plate 311 away from the oil outlet 34. That is, the angle between the plane where the guide plate 311 is located and the plane where the bottom of the box 31 is located can effectively guide the dripping waste oil to flow into the oil outlet 34, and avoid the splashing of waste liquid in the oil receiving box 3.

[0050] refer to Figure 6 and Figure 7 The oil outlet 34 is connected to the oil inlet pipe 35, the oil inlet pipe 35 is connected to the filter pipe 36, the filter pipe 36 is provided with several filter elements 361, the output end of the filter pipe 36 is connected to the conveying pipe 37, the conveying pipe 37 is connected to the storage box, and a ball valve is provided between the storage box and the conveying pipe 37. During the operation of the CNC machine tool head module 1, the workpiece is processed. During the process, metal or non-metal cutting debris or dust will enter the head module 1 and will also enter the oil receiving box 3 along with the waste oil. After preliminary filtration by the filter module 33, larger impurities in the waste oil will be filtered onto the filter module 33. The waste oil will enter the bottom of the box 31 and flow into the oil outlet 34. The waste oil from the oil outlet 34 will flow into the filter pipe 36. After being filtered by the multi-layer filter element 361 in the filter pipe 36, the waste oil will undergo further filtration. After the second filtration, the waste oil will be input into the conveying pipe 37. The filtered waste oil will be stored in the storage tank through the conveying pipe 37 for the next use. The ball valve installed between the conveying pipe 37 and the storage tank facilitates the control of waste oil output, making it more intelligent, convenient and fast.

[0051] The filter module 33 includes a first mounting block 331, a second mounting block 332, and a filter plate 333. The first mounting block 331 is located on one side of the housing 31, and the second mounting block 332 is located on the other side of the housing 31. One end of the filter plate 333 is mounted on the first mounting block 331, and the other end is mounted on the second mounting block 332. The first mounting block 331 and the second mounting block 332 provide the mounting base for the filter plate 333, facilitating its installation inside the housing 31 for preliminary filtration of waste oil dripping into the housing 31.

[0052] A first mounting slot 3311 is provided on the first mounting block 331, and a second mounting slot 3321 is provided on the second mounting block 332. A first locking member 3331 is provided on one side of the filter plate 333, and a second locking member 3332 is connected to the other side. The first locking member 3331 is located within the first mounting slot 3311, and the second locking member 3332 is installed within the second mounting slot 3321. When installing the filter plate 333 inside the housing 31, to ensure the filter plate 333 is stably installed, the first mounting block 331 has a first mounting slot 3311 that can mate with the first locking member 3331 of the filter plate 333, and the second mounting block 332 has a second mounting slot 3321 that can mate with the second locking member 3332 of the filter plate 333. This arrangement allows the filter plate 333 to be stably installed inside the housing 31, preventing it from falling off during operation of the head module 1 and ensuring the stability of its installation.

[0053] The installation height of the first mounting block 331 is higher than that of the second mounting block 332. Through the height difference between the first mounting block 331 and the second mounting block 332, the filter plate 333 can be set at an angle. The angled filter plate 333 facilitates the flow of waste oil along the angled direction, which can fully filter the waste oil and prevent the accumulation of waste residue in the impurities, which would cause the filter plate 333 to become clogged.

[0054] Protective plates 4 are installed on both sides of the oil receiving box 3. The protective plates 4 are set on the base plate 2. The protective plates 4 can protect the head module 1 and the oil receiving device, and also provide an installation base for the installation of the connector 41. The connector 41 is installed on the protective plate 4. One end of the connector 41 is hinged to the protective plate 4, and the other end is connected to the oil receiving box 3. The connector 41 can connect the box body 31 of the oil receiving box 3 and the protective plate 4 together. When it is not necessary to remove the oil receiving box 3, the oil receiving box 3 can be fixed to the base plate 2 through the connector 41. Specifically, screws are installed on the connector 41 located on the oil receiving box 3 to fix the position of the oil receiving box 3 and prevent the oil receiving box 3 from sliding out of the head module 1 during operation.

[0055] An accordion cover 5 is installed on the oil receiving box 3. The accordion cover 5 is located between the two guard plates 4. During the operation and processing of the head module 1 of the CNC machine tool, the accordion cover 5 can effectively block the debris and dust generated by metal or non-metal cutting during the processing from entering the head module 1, reducing its wear risk. It can form a physical barrier on the surface of the guide rail 11, reducing direct contact with external substances and effectively reducing wear caused by the external environment.

[0056] This application embodiment discloses an oil receiving device for CNC machine tools: by installing a base plate 2 at the bottom of the CNC machine tool head module 1 and sliding an oil receiving box 3 on the base plate 2, the oil receiving box 3 is located below the guide rail 11 of the head module 1, making full use of the space of the head module 1, without affecting the operation of the head module 1, and facilitating the direct collection of dripping waste oil. The length direction of the opening 321 can cover the two guide rails 11, and the width direction of the opening 321 can cover the thickness of the guide rails 11, that is, the waste oil after lubrication on the guide rails 11 can enter the oil receiving box 3 through the opening 321. The waste oil passes through the filter module 33 to filter large impurities for the first time. The filtered waste oil passes through the inclined guide plate 311 to effectively guide the dripping waste oil to the oil outlet 34. The waste oil from the oil outlet 34 flows into the filter pipe 36 by gravity. After being filtered by the multi-layer filter element 361 in the filter pipe 36, it is input into the conveying pipe 37. The filtered waste oil is stored in the storage box through the conveying pipe 37 for the next use.

[0057] This device prevents waste oil on the guide rail 11 from falling onto the worktable and the workpieces on the worktable due to its own weight, thus reducing the cleanliness of the worktable for the workers and ensuring the processing quality of the workpieces. The waste oil between the guide rail 11 and the slider drips into the oil collection box 3 below, and after preliminary filtration, it enters the oil outlet 34. The waste oil in the oil outlet 34 is filtered again by the multi-layer filter element 361 of the filter tube 36, realizing the collection of waste oil, which can be reused.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
