Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a fully protected five-axis gantry machining center. Background Technology

[0002] External guards, as crucial functional components of CNC machine tools, serve multiple purposes, including safety protection, precision maintenance, environmental protection, and moisture control. They are increasingly valued by machine tool manufacturers and end-users. Sliding doors are also standard protective features in machining centers, most commonly found in gantry machining centers. Because gantry machining centers are primarily used for processing large workpieces, their size and structural dimensions are significantly larger than other machining centers, making the design of their sliding doors a critical task.

[0003] The Chinese patent with application number "202010111892.8" and title "Sliding door device and gantry machining center" creatively combines a sliding door assembly with a telescopic assembly, providing a stable and convenient new protective linkage structure that can simultaneously meet the linkage of horizontal and vertical movement, thereby improving safety, efficiency, and automation.

[0004] The shortcomings of the existing technology are as follows: When the sliding door in the existing technology is used for a long time, due to the harsh environment of the processing center, impurities will accumulate on the transparent panel of its protective door. The existing technology generally cleans it manually. However, this cleaning method is not only inefficient and labor-intensive, but also poses certain safety hazards. Therefore, how to passively clean the transparent panel in a safer environment is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a fully protected five-axis gantry machining center to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The first movable door and the second movable door are respectively provided with a viewing plate, and the first movable door is provided with a first cleaning mechanism.

[0008] Furthermore, a second cleaning mechanism is slidably provided on the inner side of the first movable door;

[0009] As the second sliding door slides along the first sliding door, the first cleaning mechanism cleans the viewing panel on the second sliding door, and the pulling member drives the second cleaning mechanism to clean the viewing panel on the first sliding door.

[0010] In a further preferred embodiment of the present invention, the first cleaning mechanism includes a fixed rod fixedly disposed on the first movable door, and a cleaning plate is slidably disposed inside the fixed rod, the cleaning plate being locked inside the fixed rod by a locking member.

[0055] Furthermore, the first movable door 7 is rotatably provided with a rotating column 5111 and a second elastic element 73, and the pull rope 731 is wound around the rotating column 5111 and the second elastic element 73.

[0056] Furthermore, a tension spring is provided between the sliding crossbar 74 and the first movable door 7, with one end of the tension spring fixedly mounted on the first movable door 7 and the other end fixedly mounted on the tension crossbar.

[0057] Furthermore, a first mounting plate 82 is detachably provided on the second movable door 8, and the cleaning plate 52 is initially positioned corresponding to the first mounting plate 82. This invention, by positioning the cleaning plate 52 in relation to the first mounting plate 82, facilitates the disassembly and cleaning of the cleaning plate 52.

[0058] In a further embodiment of the present invention, a horizontal cover plate 703 is provided at one end of the first movable door 7 and the second movable door 8, and the horizontal cover plate 703 covers the main frame of the gantry.

[0059] In a further embodiment of the present invention, a first movable door 7 and a second movable door 8 are movably mounted on a gantry processing main frame 1. A fixed frame 11 is provided on the gantry processing main frame 1. The first movable door 7 is connected to the second movable door 8 through a first transmission assembly, and the second movable door 8 is transmitted to the fixed frame through a second connecting assembly. A resistance member is provided on the first connecting assembly. The resistance member has a blocking position and a release position. In the blocking position, the resistance member blocks the movement of the second movable door 8. In the release position, the second movable door 8 slides relative to the first movable door 7.

[0060] Furthermore, the resistance component is driven by a drive assembly to switch between the blocking position and the release position, and the drive assembly can drive the resistance component to the blocking position at any position.

[0061] This invention, by setting a connecting door assembly on the gantry processing main frame 1, and then through the set first transmission assembly and second transmission assembly, enables the second moving door 8 to move along the first moving door 7, and the first moving door 7 to slide along the fixed frame 11, that is, it can realize the linkage sliding of multiple moving doors, that is, realize a larger area of ​​opening and closing, improve the functionality of the linkage door assembly, and through the set resistance member and drive assembly, it can realize the second moving door 8 to stop and fix at any position during the opening process, that is, it can make the opening and closing of the second moving door 8 more convenient, and during the opening and closing process, it can realize automatic positioning to ensure the fixation of its moving door at that position, that is, greatly improve the functionality of the device.

[0062] Furthermore, the first movable door 7 is provided with a locking sliding groove 201, and the first transmission component is slidably disposed in the locking sliding groove 201. The frictional resistance of the resistance member acts in the locking sliding groove 201. The first transmission component includes a first sliding block 21 slidably disposed in the locking sliding groove 201. The first sliding block 21 is connected to the second movable door 8 through a drive component. The resistance member is disposed in the first sliding block 21, and the drive component passes through the first sliding block 21 and is connected to the resistance member block.

[0063] In a further embodiment of the present invention, the resistance element includes two locking blocks 212 slidably disposed on the first sliding block 21 and a first guide block 211. One end of the first guide block 211 is provided with a limiting guide post 2111, which is inserted into a guide groove 2121 opened on the locking block 212. A spring is disposed between the two locking blocks 212. Under its elastic force, the friction block can contact the friction wall on the locking sliding groove 201. When the driving component drives the limiting guide post 2111 to move, the friction block is disengaged from the friction wall by the guiding effect of the guide groove 2121. Specifically, when the driving component drives the limiting guide post 2111 to move, after the friction block is disengaged from the friction wall by the guiding effect of the guide groove 2121, the first sliding block 21 can slide along the locking sliding groove 201, that is, the position of the second moving door 8 can be adjusted.

[0064] In a further embodiment of the present invention, the driving component includes a hinge rod 22 rotatably disposed on the second movable door 8 and a transmission rod 23 rotatably disposed on the hinge rod 22. One end of the transmission rod 23 is rotatably disposed with a driving column 4, and a fixing sleeve 42 is fixedly disposed on the driving column 4. One end of the driving column 4 is inserted into the first guide block 211, and one end of the fixing sleeve 42 abuts against the first guide block 211 and can drive the first guide block 211 to move.

[0065] In a further embodiment of the present invention, both the second movable door 8 and the first movable door 7 are L-shaped, and a horizontal cover plate 703 is provided at one end of each of the second movable door 8 and the first movable door 7. The horizontal cover plate 703 is slidably mounted within a slide rail 101 on the gantry machining main frame 1. By configuring the second movable door 8 and the first movable door 7 as L-shaped mechanisms and providing a horizontal cover plate 703 at one end of each of the second movable door 8 and the first movable door 7, the present invention not only provides all-around protection for the machining center but also allows the horizontal cover plate 703 to open simultaneously when the second movable door 8 and the first movable door 7 are opened, greatly increasing the opening range.

[0066] In a further embodiment of the present invention, the second connecting component includes a second sliding block 31, and the second sliding block 31 is slidably disposed in a groove 301 opened on the fixing frame 11, and the resistance element of the second sliding block 31 fixes the second sliding block 31 in the groove 301.

[0067] In a further embodiment of the present invention, a second guide block 311 is slidably disposed inside the second sliding block 31, and a limit guide post 2111 is fixedly disposed at one end of the second guide block 311. Two locking blocks 212 are also slidably disposed on the second sliding block 31, and the limit guide post 2111 is inserted into the guide groove 2121 opened on the locking block 212.

[0068] In a further embodiment of the present invention, one end of the drive post 4 can be inserted into the second guide block 311 and drive the second guide block 311 to move.

[0069] A partition is provided on the first guide block 211. The partition includes a hinged baffle 2115 rotatably mounted on the first guide block 211. A stop 421 is fixedly mounted on one end of the fixed sleeve 42. The stop 421 is positioned on the hinged baffle 2115. A release groove 2113 adapted to the stop 421 is provided on the first guide block 211. A curved groove 2114 is provided at one end of the release groove 2113. The other end of the curved groove 2114 is located at the position of the hinged baffle 2115.

[0070] In a further embodiment of the present invention, a drive rack 32 is provided on the first movable door 7, and a transmission gear 41 that can mesh with the drive rack 32 is provided on the drive column 4. When the drive rack 32 meshes with the transmission gear 41, it drives the fixed sleeve 42 to rotate, and causes the stop block 421 on the fixed sleeve 42 to move into the release groove 2113.

[0071] With the structure described above, this application enables the following: when the drive rack 32 meshes with the transmission gear 41, the drive pin 4 is inserted into the second guide block 311 and drives the second guide block 311 to move synchronously.

[0072] Specifically, to prevent the drive column 4 from disengaging when inserted into the second guide column, this application provides a passive locking assembly on the second sliding block 31. The passive locking assembly includes a sliding stop bar 312 slidably mounted on the second guide block 311 and a first drive rod 3121 rotatably mounted on the second sliding block 31. A second drive rod 3123 is rotatably mounted at one end of the first drive rod 3121. It also includes a pressing block 3124 slidably mounted on the second sliding block 31, with one end of the pressing block 3124 inserted into a sliding groove 3122 on the second drive rod 3123. In the initial state, the pressing block 3124 presses against the fixing frame 11, causing the two sliding stops 312 to retract into the second guide block 311, facilitating the lateral movement of the drive column 4 into the second guide block 311 and driving the second guide block 311 and the second sliding block 31 to move. A compression spring 3125 is provided on the outside of the compression block 3124, and one end of the compression spring 3125 abuts against the inside of the second guide block 311. Then, when the compression column does not contact the fixing frame 11, it is ejected under the elastic force of the elastic element provided inside it. A spring is provided between the sliding stop bar 312 and the second guide block 311, and under its elastic force, the sliding block is pushed out to the outside of the second guide block 311.

[0073] In other words, the present invention, through the cooperation of the second connecting component and the first connecting component, enables stopping and fixing at any position, making it easier to open and close the second moving door 8. Furthermore, during the opening and closing process, automatic positioning is achieved, ensuring the stability of the moving door at that position, thus greatly improving the functionality of the device. When opening the first moving door 7, the driving force of the drive component is automatically transmitted to the second guide block 311 through the first guide block 211, which then drives the second guide block 311 and the second sliding block 31 connected to it to slide. This causes the first moving door 7 connected to the second guide block 311 to move. By driving the drive component, the size of the opening door can be selected according to user needs, and the position of the door can be fixed by controlling the drive component, preventing the opened door from sliding left or right. Not only can the position of the door be controlled arbitrarily, but it can also be quickly locked, thereby greatly improving the usability of the second moving door 8 and the first moving door 7.

[0074] Furthermore, the drive assembly also includes a handle 24 fixedly mounted on the second movable door 8 and a sliding grip rod 241 slidably mounted on the handle 24. One end of the sliding grip rod 241 is connected to a rod that is movably connected to the hinge rod 22. That is, when adjusting the door opening and closing, this application only needs to hold the sliding grip rod 241 to drive the sliding grip rod 241 to slide into the handle 24, and then the hinge rod 22 can drive the movement.

[0075] When adjusting the second movable door 8, when the second movable door 8 is opened from closed, the sliding handle 241 must first be grasped, which will cause the sliding handle 241 to slide into the handle 24, and then drive the hinge rod 22 to move. Then the hinge rod 22 moves along its hinge axis, thereby driving the transmission rod 23 to move towards the first movable door 7, so that the stop 421 on the fixed sleeve 42 connected to the transmission rod 23 abuts against the hinge baffle 2115 provided on the first guide block 211. Then, with continued movement, the first guide block 211 is squeezed towards the locking block 212, and then the limiting guide post 2111 gradually squeezes the guide groove 2121. Then, the two locking blocks 212 are gradually moved toward the first guide block 211, so that the surfaces of the two locking blocks 212 are disengaged from the inner wall of the locking sliding groove 201, that is, the inner wall of the locking sliding groove 201. At this time, they can be disengaged. Then the first sliding block 21 can slide along the locking sliding groove 201, and the second moving door 8 can be opened. When it stops at any position, just release the force on the sliding handle 241, which will cause the stop block 421 on the fixed sleeve 42 to disengage from the first guide block 211. Then, under the elastic force of the spring between them, the two locks move to the friction wall of the locking sliding groove 201, that is, they can be locked quickly.When the first movable door 7 needs to be opened, the second movable door 8 is continuously moved, causing the drive column 4 to gradually move towards the second guide block 311. During this movement, the drive rack 32 meshes with the transmission gear 41, driving the fixed sleeve 42 to rotate and causing the stop block 421 on the fixed sleeve 42 to move into the release groove 2113. At this time, the drive rack 32 and the transmission gear 41 remain meshed, meaning that the power of the drive column 4 no longer acts on the first guide block 211. Then, with continued movement, the end of the drive column 4 will enter... The second guide block 311 moves inward, and the driving column 4 gradually presses the inclined surface inside the second guide block 311, and then gradually presses the guide block inward. That is, the second guide column can press the locking block 212 located in the second sliding block 31 to disengage from the friction wall, and then drive the first moving door 7 to move along the direction of the fixed frame 11. Based on the above principle, after moving to any position, the sliding handle 241 can be released. And when the second sliding block 31 moves, the pressing block 3124 will gradually disengage from the side wall of the fixed frame 11, and then in its When the spring 3125 is compressed and springs back, the sliding stop 312 is also pushed out by the spring force, thus preventing the drive column 4 from disengaging from the second guide block 311. When it is necessary to pull back the second sliding door 8 and the first sliding door 7, when the second sliding block 31 passes the fixing frame 11, the compression block 3124 will press against the fixing frame 11. Under the compression of the inclined side of the compression block 3124, the sliding stop 312 can be driven to retract inward into the second guide block 311, thereby unlocking the fixation of the drive column 4. The drive rack 32 disengages from the second guide post, disengaging from the transmission gear 41. This causes the drive post 4 to rotate, driving the stop block 421 on the fixed sleeve 42 to move along the curved groove 2114. The stop block eventually reaches the position of the hinge baffle 2115, causing it to rotate and press against the hinge baffle 2115. At this point, the driving force is again transmitted through the stop block 421 to the first guide block 211, compressing it. Finally, the sliding grip 241 is released.

[0076] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
