Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machine tool components, and in particular to a maintenance port sealing cover structure and a CNC machine tool using the same. Background Technology
[0002] With the development of the manufacturing industry, CNC turning and milling composite machine tools have been widely used due to their high-efficiency and high-precision machining capabilities. These machine tools are typically compact in structure, integrating a variety of complex mechanical and electronic components. To facilitate subsequent maintenance of the internal structure, a large access port is usually provided on the top of the sheet metal casing. However, if the access port is not sealed, dust, debris, and other impurities from the external environment can easily fall into the machine tool. These impurities may interfere with the normal operation of the machine tool, affecting its inspection accuracy and machining quality, and ultimately leading to errors or even scrap of the processed products.
[0003] In existing technologies, a sealing cover is typically installed at the inspection port, and these covers are mostly fixed to the sheet metal housing with screws. While this fixing method ensures sufficient firmness between the sealing cover and the sheet metal housing, preventing the cover from loosening or falling off due to vibrations during machine operation, in actual maintenance operations, workers need to spend a significant amount of time using tools to unscrew multiple screws to open the sealing cover, and then retighten them all after maintenance. This cumbersome process significantly reduces maintenance efficiency and increases repair costs. Utility Model Content

[0033] Please refer to Figures 1-6 This utility model provides a maintenance port sealing cover structure, including a machine tool top cover 1 and a sealing cover unit, wherein the sealing cover unit includes a fixed beam 2 and a telescopic sealing cover 3;
[0034] The top of the machine tool cover 1 has an opening 10, and the inner walls on both sides of the opening 10 in the X-axis direction are provided with support beams 11; the fixed beam 2 is arranged in the opening 10 along the Y-axis direction and divides the opening 10 into an inspection port and an installation port 101; the installation port 101 is used to install machine tool components.
[0035] One end of the retractable sealing cover plate 3 in the X-axis direction is fixed to the side wall of the mounting port 101, and the other end of the retractable sealing cover plate 3 in the X-axis direction is detachably connected to the fixed beam 2. The two sides of the retractable sealing cover plate 3 in the X-axis direction are respectively slidably assembled to the support beam 11 on the corresponding side.
[0036] The inspection port sealing cover structure is equipped with a fixed beam 2 and a retractable sealing cover 3. Through the cooperation of the fixed beam 2 and the retractable sealing cover 3, the inspection port can be opened and closed quickly, improving the machine tool maintenance efficiency, while effectively preventing external debris from entering the machine tool.
[0037] When the machine tool is running normally, the retractable sealing cover 3 is in the unfolded state, which can cover the entire inspection port and effectively prevent dust, debris and other foreign objects in the external environment from entering the machine tool, ensuring the normal operation of the machine tool and improving the inspection accuracy and processing quality of the machine tool. When the machine tool needs to be repaired, the retractable sealing cover 3 can be pushed horizontally to the fixed end side, so that the retractable sealing cover 3 is in the folded state, thereby exposing the inspection port.
[0038] Specifically, the bottom of the retractable sealing cover plate 3 is provided with protruding ridges at intervals along the X-axis direction, and each of the protruding ridges is provided with a sliding magnet block 301, which is magnetically connected to the support beam 11.
[0039] In one specific embodiment of this utility model, the support beam 11 is made of a magnetic metal material, such as steel or an iron-nickel alloy, so that the sliding magnet block 301 can be connected to the support beam 11 through magnetism, and the sliding magnet block 301 can slide on the support beam 11. Furthermore, the retractable sealing cover 3 is a bellows cover, which is composed of several folding units. Each folding unit includes a first upper inclined plate 31, an upper horizontal plate 32, a second upper inclined plate 33, a first lower inclined plate 34, a lower horizontal plate 35, and a second lower inclined plate 36. One side of the upper horizontal plate 32 is connected to the upper end of the first upper inclined plate 31, and the other side of the upper horizontal plate 32 is connected to the upper end of the second upper inclined plate 33; one side of the lower horizontal plate 35 is connected to the lower end of the first lower inclined plate 34, and the other side of the lower horizontal plate 35 is connected to the lower end of the second lower inclined plate 36; the lower end of the first upper inclined plate 31 is connected to the upper end of the first lower inclined plate 34. The lower end of the second upper inclined plate 33 is connected to the upper end of the second lower inclined plate 36, making the cross-section of the folding unit hexagonal. The first lower inclined plate 34, the lower horizontal plate 35, and the second lower inclined plate 36 form a convex ridge. The connection between the first upper inclined plate 31 and the first lower inclined plate 34 forms a first connection area, and the connection between the second upper inclined plate 33 and the second lower inclined plate 36 forms a second connection area. The folding unit is connected to the second connection area of the previous folding unit through the first connection area, and to the first connection area of the next folding unit through the second connection area. Several folding units are connected sequentially to form an accordion cover. A sliding magnet block 301 is disposed on the bottom surface of the lower horizontal plate 35.
[0040] The accordion cover is made of highly flexible and durable materials, such as special rubber or flexible plastic, ensuring a smooth folding process and preventing damage. It allows the folding units to rotate relative to each other, thereby achieving the horizontal telescopic folding function of the cover.
[0041] With the above structure, when the retractable sealing cover 3 is switched from the folded state to the unfolded state, the included angles between the upper horizontal plate 32 and the first upper inclined plate 31, the upper horizontal plate 32 and the second upper inclined plate 33, the lower horizontal plate 35 and the first lower inclined plate 34, and the lower horizontal plate 35 and the second lower inclined plate 36 all gradually increase, while the included angles between the second upper inclined plate 33 and the second lower inclined plate 36, and the second upper inclined plate 33 and the second lower inclined plate 36 gradually decrease, thereby increasing the length of the retractable sealing cover 3 in the X-axis direction.
[0042] Conversely, when the retractable sealing cover 3 is switched from the unfolded state to the folded state, the included angles between the upper horizontal plate 32 and the first upper inclined plate 31, the upper horizontal plate 32 and the second upper inclined plate 33, the lower horizontal plate 35 and the first lower inclined plate 34, and the lower horizontal plate 35 and the second lower inclined plate 36 all gradually decrease, while the included angles between the second upper inclined plate 33 and the second lower inclined plate 36, and the second upper inclined plate 33 and the second lower inclined plate 36 gradually increase, thereby reducing the length of the retractable sealing cover 3 in the X-axis direction.
[0043] Specifically, the support beam 11 is provided with a sliding groove 110 along the X-axis direction. The sliding groove 110 is adapted to the shape of the sliding magnet block 301, and the sliding magnet block 301 is slidably assembled in the sliding groove 110.
[0044] The above structure allows the sliding magnet block 301 to slide within the sliding groove 110. The sliding groove 110 limits the path of the sliding magnet block 301, ensuring that it can only move along the straight line of the sliding groove 110, preventing unnecessary deviations in other directions, and improving the stability of the retractable sealing cover 3 when it is switched from a folded state to an unfolded state, or from an unfolded state to a folded state.
[0045] Preferably, the bottom surface of the sliding magnet block 301 is provided with a semi-circular arc surface.
[0046] By adopting the above structure, the frictional resistance between the sliding magnet block 301 and the support beam 11 is reduced, making the sliding process of the sliding magnet block 301 easier when the retractable sealing cover 3 is switched from the folded state to the unfolded state, or from the unfolded state to the folded state, thus ensuring the smooth operation of the retractable sealing cover 3.
[0047] Optionally, the support beam 11 is provided with a sealing rubber strip 111 along the X-axis direction. The sealing rubber strip 111 is located between the telescopic sealing cover plate 3 and the support beam 11. The thickness of the sealing rubber strip 111 is adapted to the height of the sliding magnet block 301, so that the bottom of the protrusion is tightly against the top surface of the sealing rubber strip 111.
[0048] The sealing rubber strip 111 has good elasticity and flexibility. When the sliding magnet block 301 is attracted to the support beam 11, the sealing rubber strip 111 is squeezed and deformed, filling the gap between the retractable sealing cover plate 3 and the support beam 11, forming an effective seal and preventing foreign matter from entering.
[0049] Furthermore, the other end of the retractable sealing cover plate 3 in the X-axis direction is provided with a connecting plate 302, the connecting plate 302 is equipped with a first connecting magnet 303, and the fixed beam 2 is provided with a second connecting magnet 21 corresponding to the position of the first connecting magnet 303. The connecting plate 302 and the fixed beam 2 are magnetically connected through the first connecting magnet 303 and the second connecting magnet 21.
[0050] With the above structure, the retractable sealing cover 3 and the fixed beam 2 are magnetically connected by the first connecting magnet 303 and the second connecting magnet 21. The operator can easily switch the retractable sealing cover 3 from the folded state to the unfolded state, or from the unfolded state to the folded state, so as to quickly open and close the inspection port, improve the machine tool maintenance efficiency, and effectively prevent external debris from entering the machine tool.
[0051] Furthermore, a buffer film is provided on the side of the connecting plate 302 near the fixed beam 2.
[0052] In one specific embodiment of this utility model, a buffer film with a thickness of approximately 2 mm is provided on the surface where the connecting plate 302 is attached. The buffer film is made of a material with buffering and sealing properties, such as a rubber film or a silicone film. When the connecting plate 302 and the fixed beam 2 are adsorbed and attached, the film material can effectively reduce the impact sound generated during the adsorption, reducing the impact of noise on the working environment; in addition, an additional sealing barrier is formed between the connecting plate 302 and the fixed beam 2, further improving the sealing effect and preventing dust, debris and other foreign matter from entering the machine tool from the connection point.
[0053] Preferably, the support beam 11 has a first liquid guiding groove 112 recessed downward along the X-axis direction. The first liquid guiding groove 112 is disposed in the assembly gap between the telescopic sealing cover plate 3 and the side wall of the opening 10. The two ends of the first liquid guiding groove 112 are connected to the side wall of the machine tool top cover 1. The fixed beam 2 has a second liquid guiding groove 22 recessed downward along the X-axis direction. The two ends of the second liquid guiding groove 22 are adapted to the positions of the first liquid guiding groove 112 on the corresponding side.
[0054] The fixed beam 2 includes a vertical plate and a horizontal plate. The vertical plate is vertically arranged on the horizontal plate, and the horizontal plate is located on the side of the vertical plate facing away from the retractable sealing cover plate 3. The second liquid guiding channel 22 is arranged on the horizontal plate, and the second connecting magnet 21 is arranged on the vertical plate.
[0055] With the above structure, liquid flowing in from around the retractable sealing cover 3 can be guided along the first liquid guiding channel 112 to the side wall of the machine tool top cover 1, effectively preventing liquid accumulation on the support beam 11 and preventing damage to the support beam 11 due to liquid corrosion. It also prevents liquid from flowing into the machine tool interior, protecting the precision components inside and improving the reliability and stability of the machine tool operation. Similarly, the second liquid guiding channel 22 of the fixed beam 2 can guide the liquid on the fixed beam 2 to the first liquid guiding channel 112, and then through the first liquid guiding channel 112 to the side wall of the machine tool top cover 1, preventing liquid accumulation on the fixed beam 2.
[0056] Specifically, the inspection port sealing cover structure includes two sealing cover units. The two fixed beams 2 cooperate to divide the opening 10 into an installation port 101 and two inspection ports. The two inspection ports are respectively set on one side of the installation port 101. The two retractable sealing cover plates 3 are respectively set on the inspection ports on the corresponding side.
[0057] In one specific embodiment of this utility model, the inspection port sealing cover structure has two inspection ports. One inspection port is located on one side of the mounting port 101 along the Y-axis, and the other inspection port is located on the other side of the mounting port 101 along the Y-axis. Using the above structure, two sealing cover units are provided, allowing operators to select the corresponding inspection port for maintenance according to the actual situation, further improving machine tool maintenance efficiency.
[0058] This utility model provides a CNC machine tool, which uses the above-mentioned inspection port sealing cover structure.
[0059] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
