Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and in particular to a protection mechanism and a machine tool having the same. Background Art

[0002] Twin-spindle gantry machine tools are highly efficient and high-precision CNC machine tools. They feature two spindles that can operate independently or synchronously, significantly improving production efficiency and machining accuracy. These machines typically utilize advanced CNC technology and automated control, making them suitable for machining complex parts in a variety of fields, including automotive, aerospace, and mold manufacturing. With their dual-spindle design and automated control, twin-spindle gantry machine tools have become an indispensable key piece of equipment in modern manufacturing. They play a significant role in improving production efficiency, reducing costs, and ensuring product quality, and are expected to have even broader application prospects in the future.

[0003] Due to the special nature of dual-spindle gantry machine tools, the overall hoisting of the machine tool is very important for both the machine tool itself and the entire production line. First of all, as a high-value equipment, the safety of the machine tool during transportation and installation is the primary consideration. Any impact, vibration, or tilt generated during the hoisting process may cause irreversible damage to the machine tool, affecting its processing accuracy and service life. Secondly, portability must be considered. While minimizing the disassembly and assembly of accessories, the gantry machine tool can be hoisted as a whole. The overall hoisting of the machine tool is related to the layout and efficiency of the entire production line. A reasonable hoisting device can save time and cost and improve work efficiency.

[0004] The existing gantry machine tool hoisting has the following problems:

[0005] 1. The structure of the gantry machine tool is complex. Before hoisting, the gantry, electrical cabinet, beam, spindle and saddle need to be completely fixed, which is difficult to fix;

[0006] 2. The gantry machine tool is heavy. During the lifting process, the gantry machine tool is prone to shaking and collision, which makes safety accidents more likely to occur;

[0007] 3. The counterweight of the gantry machine tool needs to be neat. Inconsistent weight can easily cause the gantry machine tool to shake during hoisting. Uneven counterweights require counterweight adjustment, which increases hoisting time and reduces hoisting efficiency. Summary of the Invention

[0017] Furthermore, the protective mechanism also includes: a locking block, which is provided with at least two connecting holes, one end of the locking block is connected to the body through one connecting hole, and the other end of the locking block is connected to the sliding saddle on the body through another connecting hole; wherein the connecting hole is a strip hole.

Integrated lifting reduces the risk of individual electrical cabinets during transportation, while avoiding electrical connection problems that may be caused by improper disassembly and assembly of the electrical cabinet. Since key components such as the spindle, crossbeam and electrical cabinet are fixed by special protective mechanisms, this helps to keep the gantry machine tool's counterweight even during lifting, preventing unnecessary shaking or tilting due to center of gravity shift during lifting, thereby ensuring the safety of the lifting process and the integrity of the machine tool.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] As mentioned in the background technology, when hoisting the existing gantry machine tools as a whole, the first thing to consider is safety. Any impact, vibration or tilt generated during the hoisting process may cause irreversible damage to the machine tool, affecting its processing accuracy and service life. Therefore, it is necessary to ensure the relative balance of the hoisting process. When hoisting and fixing, it is necessary to position the components with large movements. Otherwise, during long-distance operation, the vibration of the transport vehicle will cause the main shaft, crossbeam and other components to shake violently, which will not only affect their processing accuracy and service life, but also cause irreversible damage to their internal structure in severe cases. The overall hoisting of the machine tool is related to the layout and efficiency of the entire production line. A reasonable hoisting device can save time and cost and improve work efficiency. Therefore, in order to solve the above technical problems, the protective mechanism provided by the present application is detachably arranged on the machine body 100. The protective mechanism includes a spindle fixing assembly 200, a crossbeam fixing assembly 300 and a connecting bracket 400. The spindle fixing assembly 200 clamps the spindle through the first protective splint 210 and the second protective splint 220 to prevent the spindle from shaking. The crossbeam fixing assembly 300 presses the crossbeam. The connecting bracket 400 fixes the electrical cabinet assembly. This prevents the vibration of the transport vehicle from causing the spindle, crossbeam and other components to shake violently during long-distance operation, affecting their processing accuracy and service life, and causing irreversible damage to their internal structure. The electrical cabinet assembly is fixed to the machine tool as a whole to achieve integrated hoisting. There is no need to disassemble the electrical cabinet separately for transportation. In this way, each component is protected separately, which greatly improves the safety and hoisting efficiency of the machine tool during the hoisting process.

[0034] Please refer to Figures 1 to 9 The present application provides a protective mechanism that is detachably arranged on the body 100, and the protective mechanism includes: a spindle fixing assembly 200, the spindle fixing assembly 200 includes a first protective splint 210 and a second protective splint 220, a clamping space 230 for accommodating the spindle is provided between the first protective splint 210 and the second protective splint 220, at least part of the first protective splint 210 and / or at least part of the second protective splint 220 is in contact with the spindle; a crossbeam fixing assembly 300, which is detachably arranged on the body 100, and at least part of the crossbeam fixing assembly 300 is pressed onto the crossbeam of the body 100; a connecting bracket 400, which is arranged on the body 100, and the electrical cabinet assembly of the body 100 is fixedly arranged on the connecting bracket 400.

[0035] The protective mechanism provided in this application is detachably mounted on the machine body 100 and includes a spindle fixing assembly 200, a crossbeam fixing assembly 300, and a connecting bracket 400. The spindle fixing assembly 200 includes a first protective splint 210 and a second protective splint 220. A clamping space 230 for accommodating the spindle is defined between the first and second protective splints 210 and 220, with at least a portion of the first and / or second protective splints 220 being in contact with the spindle. The crossbeam fixing assembly 300 is detachably mounted on the machine body 100, with at least a portion of the crossbeam fixing assembly 300 pressed against the crossbeam of the machine body 100. The connecting bracket 400 is mounted on the machine body 100, and the electrical cabinet assembly of the machine body 100 is fixed to the connecting bracket 400. This design ensures that the spindle will not be displaced by external shock or vibration during the hoisting process, effectively protecting the machining accuracy and service life of the spindle. The fitted design ensures the stability of the spindle under various transportation conditions and reduces the internal structural damage that may be caused by the shaking of the spindle. The crossbeam fixing assembly 300 is detachably arranged on the machine body 100, and at least part of it is directly pressed on the crossbeam, which effectively suppresses the movement of the crossbeam in the X-axis direction. This is crucial to ensure the overall structural stability of the gantry machine tool during lifting and transportation, and avoids the deformation of the crossbeam due to vibration, which in turn affects the processing performance of the machine tool. The design of the connecting bracket 400 enables the electrical cabinet assembly to be directly fixed to the machine tool, without the need to separately disassemble and package the electrical cabinet before lifting, which simplifies the preparation steps before lifting and improves the efficiency of the overall lifting. Integrated lifting reduces the risk of the electrical cabinet being transported separately, while avoiding electrical connection problems that may be caused by improper disassembly and assembly of the electrical cabinet. Since key components such as the spindle, crossbeam and electrical cabinet are fixed by special protective mechanisms, this helps to keep the gantry machine tool's weight evenly balanced during lifting, preventing unnecessary shaking or tilting due to center of gravity shift during the lifting process, thereby ensuring the safety of the lifting process and the integrity of the machine tool.

[0036] Specifically, if Figure 4As shown, the spindle fixing assembly 200 further includes a fixing bracket 240, which defines a receiving space 241 extending along the axis of the spindle. A first protective plate 210 and a second protective plate 220 are mounted on the fixing bracket 240, respectively, with a clamping space 230 communicating with the receiving space 241. The fixing bracket 240 is removably mounted on the machine body 100. The receiving space 241 within the fixing bracket 240 extends along the axis of the spindle and communicates with the clamping space 230 formed by the first and second protective plates 210 and 220. This allows for precise positioning of the spindle. Furthermore, cushioning material or design surrounding the spindle effectively absorbs vibration and shock during transportation, protecting the spindle from damage and ensuring machining accuracy and service life. The design of the fixing bracket 240 enhances the structural stability of the entire spindle fixing assembly 200, maintaining the relative stability of the spindle even under complex transportation conditions. This reduces potential safety hazards caused by spindle displacement and ensures the overall safety of the gantry machine tool during hoisting and transportation. The fixing bracket 240 is detachably mounted on the machine body 100. This means that once the gantry machine tool reaches its destination, the spindle fixing assembly 200 can be quickly removed, restoring the machine tool to normal operation. This flexibility not only improves the efficiency of the protective mechanism but also facilitates maintenance and reuse of the protective assembly, reducing equipment maintenance costs. The fixing bracket 240 is designed with compatibility with the machine body 100 in mind. Through a standardized connection method, it can be used with dual-spindle gantry machine tools of different models and sizes, improving the versatility of the protective mechanism and reducing the need to design dedicated protective assemblies for each machine tool.

[0037] In the embodiment provided in the present application, the first protective splint 210 and the second protective splint 220 are staggered along the extension direction of the fixed bracket 240. The staggered arrangement increases the contact area and angle between the main shaft and the protective splint, so that the main shaft can be supported from multiple directions when subjected to external forces, thereby significantly enhancing the fixing effect of the main shaft and effectively preventing the main shaft from displacement or shaking during lifting and transportation. This staggered structure can better disperse and absorb the impact force and vibration generated during transportation. By staggering the first protective splint 210 and the second protective splint 220, a stable structure similar to a truss is formed, thereby improving the stability of the entire protective mechanism. Due to the staggered arrangement of the first protective splint 210 and the second protective splint 220, they can fit the shape of the main shaft more closely, whether it is cylindrical or asymmetric, and can provide more precise fixation, reduce gaps caused by shape mismatch, and further ensure the safety of the main shaft. The staggered protective splints can adapt to spindles of different sizes and shapes, improving the versatility and adaptability of the protective mechanism. This allows the same set of protective components to be applied to multiple models of dual-spindle gantry machine tools, reducing the need and cost of designing customized protective mechanisms for different machine tools.

[0038] During specific implementation, the spindle fixing assembly 200 further includes: a first buffer component 250, disposed on the first protective splint 210, with at least a portion of the first buffer component 250 being in contact with the spindle; and a second buffer component 260, disposed on the second protective splint 220, with at least a portion of the second buffer component 260 being in contact with the spindle. The first buffer component 250 and the second buffer component 260 are in direct contact with the spindle, capable of absorbing the impact force caused by vehicle vibration or collision during transportation, significantly reducing the displacement and deformation of the spindle caused by vibration, and protecting the spindle's machining accuracy from being affected. The provision of the buffer component avoids direct hard contact between the spindle and the protective splint, preventing the spindle from being directly impacted by the splint and damaging its surface structure under sudden large vibrations, thereby maintaining the spindle in good condition and extending its service life. The buffer component is typically made of easily replaceable materials (such as rubber, foam plastic, etc.) and can be easily replaced after long-term use or damage, reducing maintenance costs and time while maintaining the long-term effectiveness of the spindle fixing assembly.

[0039] Furthermore, the spindle fixing assembly 200 further includes a support frame 270, which includes a connecting frame body 271 and a protective frame body 272. The connecting frame body 271 is detachably connected to the machine body 100, and the fixing bracket 240 is disposed on the connecting frame body 271. The protective frame body 272 is connected to the connecting frame body 271 and is located to the side of the fixing bracket 240. The extension direction of the protective frame body 272 is consistent with the extension direction of the fixing bracket 240, and at least a portion of the protective frame body 272 is in contact with the fixing bracket 240. The support frame 270 is detachably connected to the machine body 100 via the connecting frame body 271, while the protective frame body 272 is connected to the connecting frame body 271 and is located to the side of the fixing bracket 240. This design not only ensures a reliable connection between the spindle fixing assembly 200 and the machine body 100, but also provides lateral support for the spindle and its fixing structure through the protective frame body 272, thereby improving the structural stability of the entire fixing assembly. The extension direction of the protective frame body 272 is consistent with the extension direction of the fixed bracket 240, and at least partially fits with the main shaft, effectively preventing the lateral displacement of the main shaft during the lifting process. This design is crucial to avoiding damage to the main shaft due to lateral forces, ensuring the safety of the main shaft during transportation. The protective frame body 272 fits with the fixed bracket 240, and when the main shaft is accidentally impacted, its structure can absorb part of the impact energy, play a buffering role, further protect the main shaft from direct damage, and maintain its processing accuracy and service life. The entire spindle fixing assembly 200 not only improves the stability of the main shaft, but also optimizes the safety of the lifting process. The structural design of the support frame 270 makes it difficult for the main shaft to shake during lifting, reducing the risk of accidents caused by spindle instability during lifting.

[0040] In actual use, there are two crossbeams 110, spaced apart along the length of the machine body 100. The crossbeams include first and second oppositely disposed sides. The crossbeam fixing assembly 300 includes a first bracket 310, one end of which is connected to the machine body 100 and the other end of which is in contact with the first side of one of the two crossbeams. A support rod 320 is provided, with both ends of the support rod 320 abutting the second side of each crossbeam to support the two crossbeams. The first bracket 310 is at least partially directly abutted against the first side of the crossbeam 110, effectively reducing movement of the crossbeams in the X-axis direction. The ends of the support rod 320 abut against the second side of each crossbeam 110, forming a stable support structure spanning the two crossbeams. This further limits movement of the crossbeams and enhances their stability. This prevents deformation or displacement of the crossbeams due to vibration, particularly during long-distance transportation and hoisting, thereby protecting the machining accuracy and structural safety of the gantry machine tool. The introduction of the support rod 320 restricts the crossbeam 110 on both sides of the crossbeam 110, which not only improves the stability of the crossbeam, but also strengthens the overall structure of the gantry machine tool. During the hoisting and transportation process, the support rod 320 can provide additional rigid support, reduce the overall shaking of the gantry machine tool due to external impact or vibration, and ensure the safety of the machine tool during the hoisting process. The design of the crossbeam fixing assembly 300 takes into account the ease of operation. The installation and disassembly process of the first bracket 310 and the support rod 320 is fast and does not require complex tools or professional knowledge. The operator can quickly complete the fixing and release of the crossbeam, which improves the efficiency of the gantry machine tool during hoisting and restoration, and reduces the downtime of the production line. Since the crossbeam fixing assembly 300 is reusable, the additional cost during each hoisting and transportation process is reduced. The design of the support rod 320 fully utilizes the structural characteristics of the gantry machine tool, avoids additional changes to the crossbeam, and reduces the maintenance requirements of the machine tool. In the long run, this fixing method can save maintenance and transportation costs for the enterprise and improve economic benefits.

[0041] In the examples provided in this application, Figure 5 and Figure 6As shown, the crossbeam fixing assembly 300 also includes a second bracket 330, one end of which is connected to the machine body 100 and the other end of which is in contact with the first side surface of the other crossbeam; and at least two support rods 320, spaced apart along the length of the crossbeam. The second bracket 330 and support rods 320 cooperate to constrain the position of the other crossbeam. This design effectively prevents lateral displacement and rotation of the crossbeam during lifting and transportation, thereby improving the stability of the crossbeam. By applying a fixed force at both ends, the force on the crossbeam is more evenly distributed, reducing localized stress concentration and preventing deformation or damage to the crossbeam due to uneven force. The provision of at least two support rods 320 further enhances the rigidity of the crossbeam, reduces shake caused by vehicle vibration or road bumps during transportation, and ensures that the geometry and dimensions of the crossbeam remain unchanged during lifting and transportation, thereby ensuring the machining accuracy of the gantry machine tool. By fixing at both ends and supporting in the middle, the beam fixing assembly 300 provides an effective safety protection measure, reducing the risk of displacement or deformation of the beam during lifting and transportation, protecting the core components of the gantry machine tool from damage, and ensuring the long-term stable operation of the machine tool.

[0042] In this application, if Figure 8 As shown, the connecting bracket 400 includes a first frame 410 and a second frame 420 arranged opposite each other. The first frame 410 and the second frame 420 are connected by a third frame 430, thereby enclosing a protective space for accommodating the electrical cabinet components. The first frame 410 and / or the second frame 420 are fixedly mounted to the housing 100. The protective space formed by the first frame 410, the second frame 420, and the third frame 430 protects the electrical cabinet components from multiple directions, preventing external impact or vibration during installation and transportation, and ensuring the stability and safety of the electrical components within the cabinet. The third frame 430 serves as a connection, further stabilizing the connection between the first frame 410 and the second frame 420, forming a triangular structure. This structure significantly enhances the overall stability of the connecting bracket 400 and effectively prevents the cabinet from shaking due to structural instability during installation. The detachable design of the connecting bracket 400 means that the first frame 410 and / or the second frame 420 can be quickly fixedly installed on the body 100 without the need for complex tools and time-consuming operations, thereby simplifying the hoisting preparation process.

[0043] like Figure 7 and Figure 8As shown, the protective mechanism also includes a locking block 500, which is provided with at least two connecting holes 510. One end of the locking block 500 is connected to the machine body 100 through one connecting hole 510, and the other end of the locking block 500 is connected to the sliding saddle on the machine body 100 through the other connecting hole 510. The connecting holes 510 are bar-shaped holes. The locking block 500 is connected to the machine body 100 through a locking member (such as a bolt) passing through the bar-shaped connecting hole 510, and is simultaneously connected to the sliding saddle through the other connecting hole 510. This ensures the stability of the sliding saddle during lifting and transportation, preventing it from moving in the Y-axis direction, thereby protecting the sliding saddle and the processed parts on it from damage and maintaining processing accuracy. The bar-shaped connecting hole 510 means that the locking member can be adjusted along the bar hole within a certain range to accommodate the slight displacement of the sliding saddle due to processing requirements or machine tool adjustments, ensuring that the sliding saddle is stably and properly fixed in various situations. The use of the locking block 500 simplifies the fixing steps of the saddle, and it is fixed by a locking piece without the need for complicated operations or additional tools, saving preparation time before hoisting and improving overall work efficiency. The design of the bar-shaped connecting hole 510 increases the compatibility and flexibility of the locking block 500, enabling it to adapt to gantry machine tools of different models and sizes, as well as the fixing requirements of the saddle in different positions, improving the versatility and adaptability of the protective mechanism. Through precise fixing and adjustment functions, the locking block 500 can effectively reduce the shaking and collision of the saddle during hoisting and transportation, which is crucial to ensuring the transportation safety of the gantry machine tool in complex environments, and avoiding production line stagnation or reduced work efficiency due to damage to the saddle. The locking block 500 includes two plates connected in an L-shape, and the two plates are respectively provided with connecting holes 510 to protect the saddle in multiple directions.

[0044] The present application also provides a machine tool, including a machine body 100 and a protective mechanism. The protective mechanism is detachably arranged on the machine body 100, and the protective mechanism is the protective mechanism of the above embodiment.

[0045] The protection mechanism provided by the present application. By designing a spindle fixing assembly, the two spindles are fixed, and at the same time, a buffer space is reserved to prevent the vibration of the transport vehicle during long-distance operation from causing the spindle to shake violently, affecting its processing accuracy and service life, thereby completing the fixation of the Z axis. Since the crossbeam has a large movement in the X-axis direction, a crossbeam fixing bracket and a crossbeam fixing rod are designed to complete the fixation of the crossbeam; the saddle has a large movement in the Y-axis, and the saddle is fixed in the Y-axis direction through the saddle locking block. From then on, the main components of the dual-spindle gantry machine tool that are prone to movement are positioned to prevent the vibration of the transport vehicle during long-distance operation from causing the spindle, crossbeam and other components to shake violently, affecting their processing accuracy and service life, and causing irreversible damage to their internal structure.

[0046] The electric cabinet fixing bracket assembly is used to fix the entire electric cabinet on the machine tool, achieving integrated lifting. There is no need to disassemble and transport the electric cabinet separately. The original front and rear door anti-collision bars of the machine tool are removed, and the original threaded holes are used to install the crossbeam fixing bars. Relatively few accessories are disassembled and assembled, saving time and cost in the lifting process.

[0047] During installation, the ram, saddle, and crossbeam are located on each side of the machine, and the two spindles are positioned diagonally opposite each other, ensuring even weight distribution throughout the machine. Once the machine is securely mounted, it is lifted from two 600-degree hoisting assemblies to ensure overall stability.

[0048] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0049] The protective mechanism provided in this application is detachably mounted on the machine body 100 and includes a spindle fixing assembly 200, a crossbeam fixing assembly 300, and a connecting bracket 400. The spindle fixing assembly 200 includes a first protective splint 210 and a second protective splint 220. A clamping space 230 for accommodating the spindle is defined between the first and second protective splints 210 and 220, with at least a portion of the first and / or second protective splints 220 being in contact with the spindle. The crossbeam fixing assembly 300 is detachably mounted on the machine body 100, with at least a portion of the crossbeam fixing assembly 300 pressed against the crossbeam of the machine body 100. The connecting bracket 400 is mounted on the machine body 100, and the electrical cabinet assembly of the machine body 100 is fixed to the connecting bracket 400. This design ensures that the spindle will not be displaced by external shock or vibration during the hoisting process, effectively protecting the machining accuracy and service life of the spindle. The fitted design ensures the stability of the spindle under various transportation conditions and reduces the internal structural damage that may be caused by the shaking of the spindle. The crossbeam fixing assembly 300 is detachably arranged on the machine body 100, and at least part of it is directly pressed on the crossbeam, which effectively suppresses the movement of the crossbeam in the X-axis direction. This is crucial to ensure the overall structural stability of the gantry machine tool during lifting and transportation, and avoids the deformation of the crossbeam due to vibration, which in turn affects the processing performance of the machine tool. The design of the connecting bracket 400 enables the electrical cabinet assembly to be directly fixed to the machine tool, without the need to separately disassemble and package the electrical cabinet before lifting, which simplifies the preparation steps before lifting and improves the efficiency of the overall lifting. Integrated lifting reduces the risk of the electrical cabinet being transported separately, while avoiding electrical connection problems that may be caused by improper disassembly and assembly of the electrical cabinet. Since key components such as the spindle, crossbeam and electrical cabinet are fixed by special protective mechanisms, this helps to keep the gantry machine tool's weight evenly balanced during lifting, preventing unnecessary shaking or tilting due to center of gravity shift during the lifting process, thereby ensuring the safety of the lifting process and the integrity of the machine tool.
