Description

Technical Field

[0001] This disclosure generally relates to the field of CNC machine tool technology, and specifically to an integrated device for machine tool guideway protection and chip self-cleaning. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. After processing, various control signals are issued by the CNC device. The guide rails of CNC machine tools play a supporting and guiding role during the use of the machine tool and are one of the important components of CNC. During the machining of metal parts by CNC machine tools, metal chips will fall onto the guide rails, which can easily increase the damage between the guide rails and the sliders and reduce the service life of the guide rails.

[0003] Currently, CNC machine tool guideways are protected by adding protective covers, which extend and retract freely as the tool moves along the guideways. While traditional protective covers can prevent metal debris from falling onto the guideways, the lack of a cleaning device means that scattered metal debris will remain on the surface of the cover, requiring additional cleaning. In addition, some metal powder may interfere with the extension and retraction of the cover at the gaps, thus affecting the machining accuracy of the workpiece. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an integrated device for machine tool guideway protection and chip self-cleaning to solve the above problems.

[0013] The third air guide pipe is suspended on the top of the third protective plate and connected to the side of the third protective plate away from the second protective plate. The third air guide pipe can extend and retract inside the second air guide pipe, and the interior of the second air guide pipe is hollow to form the air guide passage.

[0014] According to the technical solution provided in the embodiments of this application, the cleaning component further includes an air intake pipe, which is located on the top of the first guard plate away from the side extending from the second guard plate. The air intake pipe is connected to the first air guide pipe, and the air guide passage is formed inside the air intake pipe. A plurality of air blowing parts are provided on the side of the air intake passage near the side extending from the second guard plate.

[0015] According to the technical solution provided in the embodiments of this application, a guiding component is also included, the guiding component comprising:

[0016] The first guide groove is formed on the side of the first air duct near the first protective plate, and the first guide groove extends along the axis of the protective cover.

[0017] A first guide portion is provided on the side of the second air duct near the second protective plate, and the first guide portion is slidably connected to the first guide groove; a second guide groove is provided on the first guide portion, and the second guide groove extends along the axis of the protective cover;

Therefore, when the protective cover is placed on the guide rail, it can freely extend and retract according to the movement of the tool, preventing metal debris from falling onto the guide rail. Furthermore, by setting a cleaning component on the protective cover, when high-pressure gas is injected into the air passage within the cleaning component, the high-pressure air can be blown out from the air outlets on both sides of the air passage, thereby cleaning the surface of the protective cover. This saves on the tedious process of manual cleaning and prevents metal powder from entering the gap between the first, second, and third protective plates, thus affecting the extension and retraction of the protective cover.

[0029] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Please refer to Figures 1-5 This application provides an integrated device for machine tool guideway protection and chip self-cleaning, comprising:

[0032] The protective cover includes a first protective plate 1, a second protective plate 2, and a third protective plate 3. The inner sidewall of the first protective plate 1 is slidably connected to the outer sidewall of the second protective plate 2, and the inner sidewall of the second protective plate 2 is slidably connected to the outer sidewall of the third protective plate 3. The bottom of the first protective plate 1, the second protective plate 2, and the third protective plate 3 forms a protective channel 4 for accommodating the guide rail.

[0033] The cleaning component includes an air guide passage 5, which is formed on the top of the protective cover and extends along the axis of the protective cover. One end of the air guide passage 5 is connected to an air supply device, and multiple air blowing parts 6 are provided on both sides of the air guide passage 5.

[0034] Specifically, such as Figure 1As shown, the protective cover provided in this application includes at least a first protective plate 1, a second protective plate 2, and a third protective plate 3. The first protective plate 1, the second protective plate 2, and the third protective plate 3 are all U-shaped and their volumes decrease sequentially. The second protective plate 2 is located inside the first protective plate 1, and the third protective plate 3 is located inside the second protective plate 2. The outer wall of the second protective plate 2 can slide relative to the inner wall of the first protective plate 1, and the outer wall of the third protective plate 3 can slide relative to the inner wall of the second protective plate 2, thereby enabling the protective cover to freely extend and retract. The bottoms of the first protective plate 1, the second protective plate 2, and the third protective plate 3 are all provided with grooves. When the protective cover retracts, the second protective plate 2 can retract into the groove of the first protective plate 1, and the third protective plate 3 can retract into the groove of the second protective plate 2. When the protective cover extends, the grooves at the bottoms of the first protective plate 1, the second protective plate 2, and the third protective plate 3 form a protective channel 4. When the protective cover is installed, the first protective plate 1, the second protective plate 2 and the third protective plate 3 are placed on the guide rail of the machine tool. At this time, the guide rail is placed in the protective channel 4. The first protective plate 1 is located on the side away from the tool and is fixed to the inner wall of the machine tool. The third protective plate 3 is located on the side close to the tool and is fixed to the base that drives the tool to slide along the guide rail. When the machine tool is working, the protective cover extends and retracts along the axial direction as the tool moves, thereby blocking metal chips outside the protective cover.

[0035] Specifically, the air passage 5 of the cleaning component includes multiple air passages, which are respectively set on the top of the first protective plate 1, the second protective plate 2, and the third protective plate 3. The multiple air passages are connected in sequence to form the air passage 5. The air passage 5 extends and retracts with the extension and retraction of the protective cover. The end of the air passage 5 located on the axial position of the top of the protective cover and close to the first protective plate 1 can be connected to an external air supply device. Multiple air blowing sections 6 are opened on both sides of the air passage 5. The air blowing section 6 is a through hole formed on both sides of the air passage 5. The air blowing section 6 is connected to the air passage. High-pressure air is filled into the air passage 5 through the air supply device, so that air can be blown outward at the position of the air blowing section 6, thereby cleaning the metal debris and dust scattered on the protective cover. On the one hand, it saves the manual cleaning process, and on the other hand, it can prevent metal debris and dust from entering the gaps between the protective plates through real-time cleaning, thereby preventing it from affecting the extension and retraction of the protective cover.

[0036] Furthermore, the first protective plate 1, the second protective plate 2, and the third protective plate 3 are arranged along the axial direction of the protective cover. One end of the second protective plate 2 extends into the first protective plate 1 and is equipped with a partition strip. One end of the third protective plate 3 extends into the second protective plate 2 and is equipped with a partition strip.

[0037] Specifically, the first protective plate 1, the second protective plate 2, and the third protective plate 3 are arranged along the axial direction of the protective cover. The direction in which the first protective plate 1, the second protective plate 2, and the third protective plate 3 slide relative to each other is the axial direction of the protective cover. Hereinafter, the first protective plate 1, the second protective plate 2, and the third protective plate 3 are collectively referred to as protective plates. To prevent some metal debris or dust from entering the gaps between the protective plates, baffle strips are also provided at the ends of the second protective plate 2 and the third protective plate 3. The baffle strips are used to improve the sealing between the protective plates. Optionally, the baffle strips are made of elastic rubber. The baffle strips are designed to ensure that they do not affect the expansion and contraction between the protective plates.

[0038] Furthermore, the first protective plate 1 has a first protrusion 8 on the top of the side extending from the second protective plate 2, and the first protrusion 8 presses against the top of the second protective plate 2; the second protective plate 2 has a second protrusion 9 on the top of the side extending from the third protective plate 3, and the second protrusion 9 presses against the top of the third protective plate 3; the first protrusion 8 and the second protrusion 9 are inclined.

[0039] Specifically, to further prevent metal shavings or dust from entering the gaps between the panels, such as Figure 1 and Figure 2 As shown, a first protrusion 8 is provided at the top edge of the first guard plate 1, and a second protrusion 9 is provided at the top edge of the second guard plate 2. Both the first protrusion 8 and the second protrusion 9 are inclined away from the first guard plate 1. When the second guard plate 2 retracts inward toward the first guard plate 1, the metal debris on the top surface of the second guard plate 2 that has not fallen off can be moved by the top surface of the first protrusion 8, preventing the metal debris from accumulating in the gap between the second guard plate 2 and the first guard plate 1, thereby preventing debris from entering the gap. The second protrusion 9 has the same function as the first protrusion 8, and will not be described further here.

[0040] Furthermore, the cleaning component also includes:

[0041] The first air guide pipe 10 is located on the top of the first protective plate 1, and the interior of the first air guide pipe 10 is hollow to form the air guide passage 5.

[0042] The second air guide pipe 11 is suspended on the top of the second protective plate 2 and connected to the side of the second protective plate 2 away from the first protective plate 1. The second air guide pipe 11 can be extended and retracted inside the first air guide pipe 10. The interior of the second air guide pipe 11 is hollow to form the air guide passage 5.

[0043] The third air guide pipe 12 is suspended on the top of the third protective plate 3 and connected to the side of the third protective plate 3 away from the second protective plate 2. The third air guide pipe 12 is retractable inside the second air guide pipe 11, and the interior of the second air guide pipe 11 is hollow to form the air guide passage 5.

[0044] Specifically, the cleaning component provided in this application includes three sections: a first air guide pipe 10, a second air guide pipe 11, and a third air guide pipe 12. The first air guide pipe 10 is integrally formed with the first protective plate 1. The first air guide pipe 10 protrudes upwards from the top of the first protective plate 1, extends along the axial direction of the protective cover, and has a hollow interior forming an air passage. The air passage within the first air guide pipe 10 can serve as a section of air guide passage 5. The second air guide pipe 11 is located above the second protective plate 2 and is suspended between it and the second protective plate 2. The end of the second air guide pipe 11 away from the first protective plate 1 is integrally connected to the top edge of the second protective plate 2. The end of the second air guide pipe 11 near the first protective plate 1 is inserted into the interior of the first air guide pipe 10 and slidably connected to the inner wall of the first air guide pipe 10. The second air guide pipe 12 extends along the axial direction of the protective cover and has a hollow interior forming an air passage 5. The protective cover extends along its axis.

The second air guide pipe 11 is connected to the first air guide pipe 10. The third air guide pipe 12 is located above the third protective plate 3 and is suspended between it and the third protective plate 3. The end of the third air guide pipe 12 away from the first protective plate 1 is integrally connected to the top edge of the third protective plate 3. The end of the third air guide pipe 12 near the first protective plate 1 is inserted into the interior of the second air guide pipe 11 and is slidably connected to the inner wall of the first air guide passage 10. The third air guide pipe 12 extends along the axis of the protective cover. The third air guide pipe 12 is hollow inside, forming an air passage. The air passage inside the third air guide pipe 12 can serve as a section of the air guide passage 5. The third air guide pipe 12 is connected to the second air guide pipe 11.

[0045] Specifically, the first air guide pipe 10, the second air guide pipe 11, and the third air guide pipe 12 are collectively referred to as air guide pipes. Multiple air blowing sections 6 are provided on both sides of the air guide pipes. Each air blowing section 6 is connected to a corresponding air guide passage 5. The air guide passage 5 is adjustable in length as the protective cover extends and retracts. The air guide passage 5 is not connected to the protective channel 4 to prevent metal debris or dust from entering the protective channel 4 through the air blowing section 6. Furthermore, to prevent metal debris from entering and clogging the air blowing section 6 when it is not blowing air, a filter screen can be installed at each air blowing section 6 to block metal debris.

[0046] Furthermore, the cleaning assembly also includes an air intake pipe 13, which is located on the top of the first guard plate 1 on the side away from the second guard plate 2. The air intake pipe 13 is connected to the first air guide pipe 10, and the air guide passage 5 is formed inside the air intake pipe 13. A plurality of air blowing parts 6 are provided on the side of the air intake passage near the second guard plate 2.

[0047] Specifically, the air intake pipe 13 is formed by the upward protrusion of the top of the first protective plate 1. The air intake pipe 13 is set perpendicular to the first air guide pipe 10. The interior of the air intake pipe 13 is hollow, forming an air passage. The air passage inside the air intake pipe 13 can serve as the air intake pipeline 5. An air inlet 7 is provided at the top of the air intake pipe 13. The air inlet 7 is used to connect with an external air supply device, thereby realizing air intake into the air guide passage 5. Multiple air blowing parts 6 are also provided on the side of the air intake pipe 13 near the first air guide pipe 10. The air blowing parts 6 on the air intake pipe 13 are used to blow air in different directions than the air blowing parts 6 on the air guide pipe, thereby improving the cleaning efficiency of the protective cover surface.

[0048] Furthermore, it also includes a guide component, the guide component comprising:

[0049] The first guide groove 14 is formed on the side of the first air duct 10 near the first protective plate 1, and the first guide groove 14 extends along the axis of the protective cover.

[0050] A first guide portion 15 is disposed on the side of the second air duct 11 near the second protective plate 2, and the first guide portion 15 is slidably connected to the first guide groove 14; a second guide groove 16 is provided on the first guide portion 15, and the second guide groove 16 extends along the axis of the protective cover.

[0051] The second guide portion 17 is disposed on the side of the third air duct 12 near the third protective plate 3, and the second guide portion 17 is slidably connected to the second guide groove 16.

[0052] Specifically, such as Figures 3-5 As shown, the first guide groove 14 is formed on the lower inner wall of the first air guide pipe 10, and the first guide groove 14 is not connected to the protective channel 4; the first guide part 15 is integrally formed on the bottom wall of the second air guide pipe 11, and the first guide part 15 is suspended from the top surface of the second protective plate 2. When the second air guide pipe 11 is inserted into the first air guide channel 10, the first guide part 15 is inserted into the first guide groove 14. The cooperation between the first guide part 15 and the first guide groove 14 makes the sliding of the second air guide pipe 11 more stable. The second guide groove 16 is formed on the lower inner wall of the second air guide pipe 11, and the second guide part 17 is integrally formed on the bottom wall of the third air guide pipe 12, and the second guide part 17 is suspended from the top surface of the third protective plate 3. When the third air guide pipe 12 is inserted into the second air guide channel 11, the second guide part 17 is inserted into the second guide groove 16. The cooperation between the second guide part 17 and the second guide groove 16 makes the sliding of the third air guide pipe 12 more stable.

[0053] Furthermore, the second air guide pipe 11 is provided with a sealing strip 18 at one end that extends into the first air guide pipe 10, and the third air guide pipe 12 is provided with a sealing strip 18 at one end that extends into the second air guide pipe 11.

[0054] Specifically, such as Figure 4 and Figure 5 As shown, by providing sealing strips 18 at the ends of the second air duct 11 and the third air duct 12, the sealing between the air ducts can be improved, thereby enabling the blowing part 6 to generate a stronger airflow and improve cleaning efficiency; optionally, the sealing strip 18 is made of rubber.

[0055] Furthermore, the top surfaces of the first protective plate 1, the second protective plate 2, and the third protective plate 3 are each provided with a plurality of heat sinks 19, which extend into the protection channel 4 and are distributed on both sides of the air guide passage 5.

[0056] Specifically, since the protective cover encloses the guide rail, a heat dissipation mechanism is required on the protective cover to prevent the guide rail from overheating due to tool movement. This application provides multiple heat sinks 19 on the top surfaces of the first guard plate 1, the second guard plate 2, and the third guard plate 3, such as... Figure 1 As shown, multiple heat sinks 19 are embedded on the top surface of the protective plate and distributed on both sides of the air guide channel. One side of the heat sink 19 is placed outside the protective plate, and the other side is placed inside the protective plate. One side of the heat sink 19 is used to absorb the heat in the protective channel 4, and when the air blowing part 6 blows air, the heat can be dissipated outward from the other side of the heat sink 19.
