Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, specifically a fixed beam CNC gantry machining center that is easy to maintain. Background Technology

[0002] The fixed beam CNC gantry machining center is a high-precision equipment used for machining large parts. It is widely used in aerospace, automobile manufacturing, mold processing and other industries. It has the advantages of wide processing range, high precision and high efficiency.

[0003] However, existing fixed-beam CNC gantry machining centers still have some problems in use:

[0004] For example, a fixed beam gantry machining center with application number CN202421098740.9 includes a lower support platform, an outer protective shell installed on the lower support platform, a sealing door slidably installed on the outer protective shell via a guide rail, an outer support beam installed at the top front end of the lower support platform, a machining head component extending into the outer protective shell installed at the bottom end of the transverse traveling component, an inner cavity machining table movably installed on the lower support platform, an inner cavity machining table with a concave table surface, a strip groove on the concave table surface, and two positioning clamping plate components connected in the concave table surface via a central clamping structure;

[0005] Traditional fixed-beam gantry machining centers, after long-term use, suffer from limited internal space due to their compact structure and densely packed components. Maintenance requires the disassembly of numerous external components, which is not only time-consuming and labor-intensive but may also affect the equipment's accuracy and lifespan due to frequent disassembly and assembly.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was implemented based on the existing fixed-beam gantry machining center. Utility Model Content

[0008] The purpose of this utility model is to provide a fixed beam CNC gantry machining center that is easy to maintain, in order to solve the problem mentioned in the background art that after long-term use, the fixed beam gantry machining center has a small internal space due to its compact structure and dense components. Maintenance requires the disassembly of a large number of external components, which is not only time-consuming and labor-intensive, but may also affect the accuracy and service life of the equipment due to frequent disassembly and assembly.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A maintenance-friendly fixed-beam CNC gantry machining center includes a column and a crossbeam. The crossbeam is positioned above the column, and a groove is formed at the top of the column. A protrusion matching the groove is fixed to the bottom of the crossbeam, and a slot is formed on the outer side of the protrusion. Two sets of sliding grooves are symmetrically formed at the top of the column. A handwheel is mounted on the outside of the column, and a threaded rod is fixed to the end of the handwheel, penetrating the column and extending to the middle of the sliding groove. The end of the threaded rod is movably connected via a bearing to a locking block that engages with the slot. A connecting arm is mounted on the outside of the column, and a housing is fixed to the other end of the connecting arm. An integrated control module is housed inside the housing, and a fixing plate is fixed to the inner top of the housing. A motor is mounted on the outside of the housing, and a lead screw is movably connected to the output end of the motor. The other end of the lead screw is rotatably connected to the fixing plate via a bearing. A slider is threaded onto the outer surface of the lead screw, and the slider is fixedly connected to the integrated control module.

[0011] By adopting the above technical solution, the crossbeam protrusion and the column groove cooperate, and the handwheel drives the threaded rod to make the locking block lock into the slot to achieve a stable connection, realizing convenient and reliable assembly of the column and crossbeam; the motor drives the lead screw to rotate, which drives the slider and integrated control module to move. At the same time, the position of the integrated control module can be adjusted by the motor and lead screw to meet different usage requirements.

[0012] Preferably, the outer end of the threaded rod is sleeved and threaded with a lock nut.

[0013] By adopting the above technical solution, the threaded structure of the threaded rod and the locking nut is utilized. When the locking nut is rotated, it can move along the threaded direction on the threaded rod. After the threaded rod drives the locking block to complete the engagement with the locking groove, tightening the locking nut can prevent the threaded rod from rotating, thereby ensuring the stable engagement of the locking block and the locking groove and enhancing the stability of the structural connection.

[0014] Preferably, two sets of the locking blocks are symmetrically arranged along the column, and two sets of limiting shafts are fixed on one side of the locking blocks, with the limiting shafts passing through the middle of the column and extending to the outside of the column.

[0015] By adopting the above technical solution, a channel for the limiting shaft to pass through is set on the column, so that the locking block forms a sliding connection with the column with the help of the limiting shaft. Under the drive of the threaded rod, the locking block can move in a specific direction, which can prevent the locking block from deviating during the movement and ensure that the locking block accurately matches the locking slot.

[0016] Preferably, the bottom of the housing is fixed with a slide rail, and two sets of slide rails are symmetrically arranged along the inside of the housing. The bottom of the integrated control module is equipped with two sets of slide rails that are slidably connected to the slide rails.

[0017] By adopting the above technical solution, the slide rail and slide track are matched in shape and structure, so that the slide track can be embedded in the slide track and slide freely in a specific direction. The integrated control module is driven by the motor drive screw, which in turn makes the slide track move in the slide track. The two sets of symmetrical slide tracks and slide tracks provide stable guidance for the movement of the integrated control module, ensuring that it moves smoothly and accurately in a straight line in the box and preventing deviation or shaking during the movement.

[0018] Preferably, a processing head is installed in the middle of the crossbeam, and a processing platform is provided directly below the crossbeam.

[0019] By adopting the above technical solution, a stable frame structure is built by columns and beams. The processing head is installed in the middle of the beam, placing it in a suitable working position. The processing platform is set directly below the beam, forming a vertical working layout with the processing head, providing basic support for processing operations. The processing head can accurately process the workpiece placed on the processing platform, meeting the needs of different processing technologies and achieving an efficient and stable processing process.

[0020] Preferably, protective doors are vertically installed on both sides of the processing platform, and the middle of the protective doors adopts a double-opening observation window design.

[0021] The above technical solution involves vertically installing movable protective doors on both sides of the processing platform, using hinges and other connecting structures to open and close the protective doors. The double-opening observation windows are made of transparent material and are installed in the middle of the protective doors through reasonable division, so as not to affect the line of sight. The protective doors can be closed during processing to prevent debris, coolant splashes, etc. generated during processing from causing harm to the surrounding environment and personnel. The double-opening observation windows allow operators to observe the processing status of the workpieces on the processing platform at any time during the processing.

[0022] Compared with the prior art, the beneficial effects of this utility model are: this easy-to-maintain fixed-beam CNC gantry machining center...

[0023] 1. A groove is cut at the top of the column to fit the protrusion at the bottom of the crossbeam for initial positioning and installation. By rotating the handwheel, the threaded rod is rotated, causing the locking block to move along the slide groove and engage with the outer groove of the protrusion. The locking nut prevents the threaded rod from loosening, ensuring a stable and convenient connection between the column and the crossbeam. The two sets of symmetrically arranged locking blocks and limiting shafts further enhance the connection stability and restrict the movement direction of the locking blocks to prevent offset. When the equipment needs maintenance, the column and crossbeam sections can be quickly disassembled and separated, greatly reducing the amount of disassembly work, improving maintenance efficiency, and effectively avoiding the inconvenience and risk of equipment damage caused by overall disassembly.

[0024] 2. By installing a connecting arm to fix the housing on the outside of the column, an independent and safe installation space is provided for the integrated control module. The motor drives the lead screw to rotate, which moves the integrated control module, which is fixed to the slider, along the lead screw axis. At the same time, the slide rails symmetrically set at the bottom of the housing slide to connect with the slide rails at the bottom of the integrated control module, providing stable guidance for the module's movement and ensuring its smooth and precise movement. This makes it easy to move the integrated control module out of the housing, allowing maintenance personnel to clearly see the internal situation of the housing, quickly locate and solve problems, greatly improving the maintenance convenience of the integrated control module and reducing maintenance difficulty and time costs.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1-3 This utility model provides a technical solution:

[0034] A maintenance-friendly fixed-beam CNC gantry machining center includes a column 1 and a crossbeam 2. The crossbeam 2 is positioned above the column 1. A groove 6 is formed at the top of the column 1. A protrusion 7, which matches the groove 6, is fixed at the bottom of the crossbeam 2. A slot 8 is formed on the outer side of the protrusion 7. Two sets of sliding grooves 9 are symmetrically formed at the top of the column 1. A handwheel 10 is positioned outside the column 1. A threaded rod 11 is fixed at the end of the handwheel 10, and the threaded rod 11 passes through the column 1 and extends to the middle of the sliding groove 9. The end of the threaded rod 11 is movably connected to a locking block 12, which engages with the slot 8, via a bearing. A locking nut 14 is threaded and sleeved on the outer end of the threaded rod 11. Two sets of locking blocks 12 are symmetrically arranged along the column 1. Two sets of limiting shafts 13 are fixed on one side of the locking block 12, and the limiting shafts 13 pass through the middle of the column 1 and extend to the outside of the column 1.

[0035] This easy-to-maintain fixed-beam CNC gantry machining center features a groove 6 at the top of the column 1, and a matching protrusion 7 fixed to the bottom of the crossbeam 2 for initial positioning and installation of the crossbeam 2 and column 1. Two sets of slots 8 are formed on the outer side of the protrusion 7, and two sets of sliding grooves 9 are symmetrically formed at the top of the column 1. A handwheel 10 is installed on the outside of the column 1, with a threaded rod 11 fixed to its end. The threaded rod 11 passes through the column 1 to the middle of the sliding groove 9, and its end is movably connected to a locking block 12 via a bearing. When the handwheel 10 is rotated, the threaded rod 11 rotates accordingly. Because the locking block 12 is connected to the threaded rod 11 via a bearing and is restricted by the sliding groove 9, the locking block 12 moves along the sliding groove 9, thus engaging with the slots 8 on the outer side of the protrusion 7 to achieve the mounting of the crossbeam 2. A stable connection with column 1; the outer end of threaded rod 11 is sleeved and threadedly connected to locking nut 14. After the locking block 12 is engaged in the slot 8, tightening the locking nut 14 can prevent the threaded rod 11 from loosening and ensure connection stability; two sets of locking blocks 12 are symmetrically arranged along column 1 to enhance connection stability. Two sets of limiting shafts 13 are fixed on one side of the locking block 12. The limiting shafts 13 pass through the middle of column 1 and extend to the outside, which can further limit the movement direction of the locking block 12 and prevent it from deviating during movement. This ensures that the locking block 12 is accurately engaged in the slot 8, which facilitates the disassembly and separation of crossbeam 2 and column 1, greatly reduces the amount of disassembly work, improves maintenance efficiency, and avoids the inconvenience and equipment damage risk caused by overall disassembly.

[0036] Example 2

[0037] Please see Figure 4 , Figure 5 This utility model provides a technical solution:

[0038] A connecting arm 15 is installed on the outer side of the column 1. A housing 16 is fixed to the other end of the connecting arm 15. An integrated control module 17 is installed inside the housing 16. A fixing plate 18 is fixed to the inner top of the housing 16. A motor 19 is installed on the outer side of the housing 16. A lead screw 20 is movably connected to the output end of the motor 19, and the other end of the lead screw 20 is rotatably connected to the fixing plate 18 via a bearing. A slider 21 is threaded onto the outer surface of the lead screw 20, and the slider 21 is fixedly connected to the integrated control module 17. A slide rail 22 is fixed to the inner bottom of the housing 16, and two sets of slide rails 22 are symmetrically arranged along the inside of the housing 16. Two sets of slide rails 23 are installed at the bottom of the integrated control module 17 and are slidably connected to the slide rails 22.

[0039] This easy-to-maintain fixed-beam CNC gantry machining center has a connecting arm 15 mounted on the outside of the column 1, with the other end of the connecting arm 15 fixed to the housing 16, providing an installation carrier and independent space for the integrated control module 17. A fixing plate 18 is fixed to the top inside the housing 16, and a motor 19 is mounted on the outside of the housing 16. The output end of the motor 19 is movably connected to a lead screw 20, and the other end of the lead screw 20 is rotatably connected to a bearing on the fixing plate 18. When the motor 19 starts, it can drive the lead screw 20 to rotate around its own axis. A slider 21 is threadedly connected to the outer surface of the lead screw 20, and the slider 21 is fixedly connected to the integrated control module 17. The transmission of the lead screw 20... In principle, the rotation of the lead screw 20 causes the slider 21 to move along the axis of the lead screw 20, thereby driving the integrated control module 17 to move. Two sets of symmetrical slide rails 22 are fixed at the bottom of the housing 16. Two sets of corresponding sliding rails 23 are installed at the bottom of the integrated control module 17. The slide rails 23 cooperate with the slide rails 22 to provide stable guidance for the movement of the integrated control module 17, ensuring that its movement is smooth and accurate. This makes it easy to move the integrated control module 17 out of the housing 16. During subsequent maintenance, it is possible to have a good understanding of the internal situation of the housing 16 so as to deal with and solve problems in a timely manner, thereby improving the maintenance convenience of the integrated control module 17.

A machining platform 4 is positioned directly below the crossbeam 2, creating a vertically aligned layout that provides a stable and precise place for workpiece placement and processing. During processing, the workpiece is placed on the machining platform 4, and the machining head 3 performs various machining operations such as cutting and drilling according to a preset program. Protective doors 5 are vertically installed on both sides of the machining platform 4. During processing, these doors create a semi-enclosed space, effectively preventing debris, coolant splashes, and noise from spreading, thus protecting the surrounding environment and the safety of operators. The protective doors 5 feature a double-opening observation window design in the middle, allowing operators to easily and clearly observe the processing status and progress of the workpiece on the machining platform 4 in real time without opening the doors. This facilitates timely adjustments to processing parameters or handling of unexpected problems, improving processing efficiency and controllability while ensuring safety.

[0044] Working principle:

[0045] In use, the column 1 and the crossbeam 2 are initially positioned by the top groove 6 and the protrusion 7. The handwheel 10 is rotated so that the threaded rod 11 drives the locking block 12 to move along the slide groove 9 and engage with the outer locking groove 8 of the protrusion 7. The locking nut 14 is then tightened to ensure a stable connection. The outer connecting arm 15 of the column 1 fixes the housing 16.
