Description

Technical Field

[0001] This invention relates to the field of tool holder changing machining devices, and more particularly to a vertical machining device with quick tool holder changing. Background Technology

[0002] Vertical machining centers are CNC machine tools with their spindle axis perpendicular to the worktable. They can complete multiple machining operations such as milling, drilling, boring, and tapping in a single setup. The spindle, worktable, CNC system, tool magazine, and tool changer are all integrated. They offer convenient workpiece clamping, a good cutting field of view, and strong versatility, making them suitable for complex parts such as plates, discs, and small molds. The core purpose is to reduce non-cutting time, increase machine tool utilization, and improve accuracy and flexible production. They significantly shorten tool change time, improving efficiency. For multi-process parts requiring frequent tool changes, quick tool changes save considerable auxiliary time. They reduce manual intervention, lowering errors. Toolless quick changes eliminate the need for wrenches and other tools, avoiding coaxiality deviations caused by uneven tightening force. Reduced manual operation results in higher clamping accuracy consistency, ensuring stable batch processing quality. They are suitable for flexible production and small-batch, multi-variety production, extending equipment life, reducing maintenance costs, and avoiding thread stripping and clamp deformation caused by repeated bolt disassembly and assembly. This reduces spare parts replacement, minimizes downtime, increases the proportion of effective machine tool processing time, and improves return on investment.

[0003] As the manufacturing industry transforms towards high precision, high efficiency, flexibility, and automation, traditional vertical machining centers suffer from several drawbacks. These include extremely low tool holder replacement efficiency. Traditional systems rely on bolt-locking and manual disassembly / reassembly for tool holder fixation, resulting in a cumbersome and time-consuming process, with each tool change taking several minutes. This significant amount of non-cutting auxiliary time occupies the machining cycle, leading to severely low equipment utilization. Furthermore, workpiece clamping and worktable flexibility are insufficient. Workpiece clamping mechanisms are mostly fixed structures, and the worktable lacks flexible adjustment functions such as horizontal displacement and height adjustment, making it unsuitable for workpieces of different specifications and machining positions. This limits the machining range and reduces the system's versatility. Finally, machining accuracy and consistency are difficult to guarantee, as tool changing, clamping, and adjustment all rely on manual operation, which is prone to errors. Problems such as uneven locking force, tool positioning deviation, and clamping misalignment cause fluctuations in coaxiality and dimensional accuracy, resulting in poor quality stability in batch processing. The processing functions are limited, and the procedures are cumbersome. Traditional equipment can only perform single or a few processing steps; complex workpieces require multiple clamping operations and multi-device coordination, leading to continuous accumulation of clamping errors, lengthy processing flows, and low overall production efficiency. Equipment maintenance costs are high; repeated disassembly and reassembly of bolts can easily cause thread stripping and structural deformation in components such as tool holders and spindles, resulting in high equipment failure and downtime maintenance frequency and shortened service life. Furthermore, it has poor adaptability to flexible production; facing the trend of small-batch, multi-variety production, traditional equipment cannot quickly switch tools and processes, resulting in slow production response and difficulty in adapting to the demands of modern flexible manufacturing.

[0004] To address the aforementioned problems, a vertical machining device with a quick tool holder change function is proposed. Summary of the Invention

[0026] The present invention has the following beneficial effects:

[0027] 1. In this invention, the tool holder can be changed quickly, and the efficiency is improved many times over.

[0028] 2. In this invention, the workpiece is automatically clamped and the worktable is flexibly adjustable, maximizing its versatility. The fixing component uses a cylinder-driven limit block and fixing block to achieve automated and precise workpiece clamping, avoiding the problems of loosening and misalignment caused by manual clamping. The adjustment component uses a motor, threaded rod, and cylinder linkage to drive the worktable to achieve horizontal displacement, height adjustment, and precise limiting, which can adapt to workpieces of different sizes and processing positions, improving the processing range and greatly enhancing the versatility of the vertical processing device.

[0029] 3. In this invention, multi-process composite processing is performed and formed in one clamping.

This avoids the accumulation of errors caused by multiple clamping of the workpiece, improves the processing accuracy, simplifies the processing process, and reduces the coordination cost of multiple vertical processing devices.

[0030] 4. In this invention, the entire process is automated, with excellent precision and consistency. The vertical machining device is uniformly controlled by the controller, and the entire process of machining, tool changing, adjustment, and clamping is executed automatically, avoiding human operation errors. With the precise guidance of the slide rail and slider, the threaded rod provides smooth transmission, and the coaxiality of the tool holder positioning and the consistency of the workpiece machining dimensions reach high precision standards, making it suitable for batch standardized production.

[0031] 5. In this invention, the vertical machining device reduces maintenance costs and extends lifespan. It eliminates the need for repeated disassembly and assembly of traditional bolts, avoiding slippage and deformation of core components such as tool holders and spindles, thus reducing the frequency of downtime for maintenance. The wear-resistant slide rail and slider design results in extremely low component wear, significantly extending the overall lifespan of the vertical machining device. It is suitable for flexible production and can quickly respond to market demands. The quick tool change function, combined with an adjustable worktable, allows for rapid switching of tools and machining processes without long downtime for debugging. It is perfectly suited for flexible production modes with small batches and multiple varieties, significantly improving production response speed and market competitiveness.

[0032] 6. This invention features comprehensive functions, ensuring both processing safety and quality.

This design is for the threaded rod 403 to be rotatably connected to the inner wall of the fixed seat 404, and the connecting plate 405 to be fixedly connected to the bottom of the limiting plate 409.

[0066] In this embodiment, the fixed base 404 provides stable rotational support for the threaded rod 403, effectively reducing radial runout and component wear, and ensuring long-term stable operation. The connecting plate 405 accurately converts the rotational motion of the threaded rod 403 into the linear translational motion of the limiting plate 409, resulting in high transmission efficiency, small positioning error, simplified transmission logic of the adjustment component 4, reduced failure probability of the vertical processing device, and, in conjunction with the lifting adjustment of the cylinder 406, achieved precise adjustment of the worktable in both horizontal and vertical dimensions, adapting to various workpiece processing requirements, improving the operational stability of the vertical processing device, reducing maintenance costs, and significantly extending the service life of the adjustment component 4.

[0067] The threaded rod 3 503 is rotatably connected to the inner right side of the mounting bracket 3 501, and the movable plate 505 is slidably connected to the outer wall of the two slide rails 3 504. This design is for the threaded rod 3 503 to be rotatably connected to the inner right side of the mounting bracket 3 501, and the movable plate 505 to be slidably connected to the outer wall of the two slide rails 3 504.

[0068] In this embodiment, mounting bracket 3 501 ensures that threaded rod 3 503 rotates without deviation, and slide rail 3 504 provides linear and precise guidance for moving plate 505, avoiding problems such as lifting jamming and shaking; threaded rod 3 503 and moving plate 505 adopt precision thread transmission to achieve micron-level height adjustment of tool holder 508, greatly improving the adjustment accuracy of tool assembly 5, and quickly changing tools with tool changing assembly 6, so that the coaxiality of tool holder and machining head 313 meets the standard, avoiding machining dimensional deviation; at the same time, it reduces component friction wear, avoids thread stripping failure, reduces the operation and maintenance cost of vertical machining device, and effectively improves tool adjustment efficiency and machining stability.

[0069] Multiple sliders 605 are fixedly connected to the rear top and top of the connecting plate 606, and multiple cutter heads 610 are snapped into the inner wall of the cutter holder 508. This design is to ensure that multiple sliders 605 are fixedly connected to the rear top and top of the connecting plate 606, and multiple cutter heads 610 are snapped into the inner wall of the cutter holder 508.

It can be quickly changed with electric push rod 603. The snap-fit ​​structure can prevent the cutter head 610 from loosening during cutting, improving machining stability; at the same time, it eliminates the traditional method of repeated bolt disassembly and assembly, avoids stripping and deformation of the inner wall of tool holder 508, extends the service life of tool holder 508 and cutter head 610, reduces the frequency of equipment downtime for maintenance, and ensures continuous processing efficiency.

[0071] Both limit blocks 706 are fixedly installed on the inner wall of connecting block 2 707, and the output ends of both cylinders 3 703 pass through the inner wall of limit plate 3 704. This design is for the two limit blocks 706 to be fixedly installed on the inner wall of connecting block 2 707, and the output ends of both cylinders 3 703 to pass through the inner wall of limit plate 3 704.

[0072] In this embodiment, the limiting plate 704 precisely limits the output stroke of the cylinder 703 to prevent excessive clamping force from damaging the workpiece or insufficient clamping force from causing displacement; the limiting block 706 is rigidly connected to the connecting block 707, and the transmission response is rapid, so that the fixing block 708 clamps the workpiece synchronously and the force is uniform, which significantly improves the clamping accuracy of the fixing component 7, eliminates the problem of uneven force during manual clamping, ensures that the size of batch processed workpieces is consistent, and can be adapted to workpieces of different materials and sizes, further improving the versatility of the device and the processing quality, and reducing the workpiece scrap rate.

[0073] Multiple sliders 305 are fixedly connected to the rear side of mounting plate 306, and multiple sliders 308 are fixedly connected to the rear side of mounting plate 310. This design is for the purpose of fixing multiple sliders 305 to the rear side of mounting plate 306 and multiple sliders 308 to the rear side of mounting plate 310.

[0074] In this embodiment, slider 305 and slide rail 304, and slider 308 and slide rail 307 form a dual-guide stabilizing structure, providing reliable support for mounting plate 306 and mounting plate 310, effectively preventing vibration-induced displacement during processing. Multiple sliders distribute the force, improving the overall structural strength and operational stability of the processing assembly 3. This structure ensures accurate positioning of the processing head 313, reduces processing errors caused by vibration, and enhances precision machining capabilities. Combined with rapid tool change and multi-process machining functions, it extends the service life of the processing assembly 3, increases the proportion of effective processing time, and meets the needs of continuous unattended processing.

[0075] Working principle: After the vertical machining device is powered on and started, the controller 11 immediately performs a system self-test, scanning the status of the machining component 3, adjustment component 4, tool component 5, tool changer component 6, fixing component 7 and driver 9. The warning light 12 lights up green, indicating that all components are normal and the vertical machining device enters the standby state, ready for subsequent processing. After the operator places the workpiece to be processed in the processing area of ​​the fixing component 7, the operator inputs the processing parameters through the controller 11, and the device automatically enters the operation process.

[0076] First, the automatic workpiece clamping process is executed. The cylinder 703 in the fixed assembly 7 receives an electrical signal from the controller 11 and is activated. Its output end extends and pushes the limit block 706 to move directionally along the inner wall of the limit plate 704. The limit block 706 drives the connecting block 707 to rotate synchronously around the connecting seat 705, which in turn drives the fixed block 708 to move smoothly towards the center of the workpiece, quickly completing the automatic and precise clamping of the workpiece. The limit plate 704 strictly limits the extension stroke of the cylinder 703, so that the clamping force is uniform and moderate. This avoids the workpiece from loosening and shifting during processing, and also prevents the workpiece from being deformed due to over-clamping. The entire process does not require manual clamping, avoiding problems such as uneven clamping force and positioning deviation. It ensures the workpiece clamping accuracy and batch processing quality stability from the source.

[0077] After the workpiece is clamped, the adjustment component 4 is activated, achieving precise adjustment of both the horizontal displacement and height of the worktable. Motor 2 402 drives threaded rod 2 403 to rotate smoothly within the fixed base 404. Threaded rod 2 403, through precision thread transmission, drives connecting plate 1 405 to move horizontally. Connecting plate 1 405 then pushes limiting plate 2 409 to slide along the bottom of limiting plate 1 408, completing precise horizontal positioning of the worktable. Simultaneously, cylinder 2 406 is activated, its output end extending and retracting to raise and lower connecting rod 407. Connecting rod 407 drives limiting plate 1 408 to move up and down, achieving adaptive adjustment of the worktable height. The adjustment component 4, through the coordinated operation of the motor, cylinder, and threaded rod, can quickly adapt to workpieces of different sizes and processing positions, significantly expanding the processing range and improving the versatility of the device. Furthermore, the fully automated adjustment eliminates the need for manual intervention, effectively reducing positioning errors caused by manual adjustment and laying a solid foundation for subsequent precision machining.

[0078] After the worktable is adjusted to the correct position, the tool assembly 5 and the tool changer assembly 6 work together to complete the core rapid tool holder change process. The electric push rod 603 in the tool changer assembly 6 is activated, driving the connecting plate 2 606 to move horizontally along the slide rail 4 604. The slider 3 605 slides synchronously with the connecting plate 2 606, ensuring that the tool disc 609 moves smoothly to the precise docking position of the tool holder 508. Then, the drive mechanism 608 operates, driving the tool disc 609 to rotate, rotating the tool head 610 of the required specifications to the docking position. The electric push rod 603 continues to advance slightly, allowing the tool head 610 to quickly engage with the inner wall of the tool holder 508, completing the automatic tool holder change. This tool changing process abandons the traditional bolt-locking and manual disassembly mode, and is fully automated, taking only a few seconds to complete. It significantly reduces the traditional tool changing time of several minutes, greatly reduces non-cutting auxiliary time, and improves the effective utilization rate of vertical machining equipment. The inner wall of the tool head 609 is evenly arranged with multiple specifications of tool heads 610, which can be quickly switched to adapt to different machining processes such as milling, drilling, boring, tapping, and cutting off, perfectly adapting to the flexible production needs of small batch and multi-variety production.

[0079] After the tool holder is replaced, the tool assembly 5 starts the tool height adjustment process: the motor 3 502 drives the thread rod 3 503 to rotate, which drives the moving plate 505 to rise and fall smoothly along the slide rail 3 504. The fixed block 1 506 moves synchronously with the moving plate 505, thereby adjusting the height of the driver 2 507 and the tool holder 508, so that the tool head 610 and the processing head 313 of the processing assembly 3 are precisely aligned, ensuring that the coaxiality of the processing meets the standard.

[0080] Entering the core processing stage, processing component 3 fully starts to execute multi-process composite processing. Motor 302 drives threaded rod 303 to rotate, causing mounting plate 306 to move horizontally along slide rail 304. Cylinder 309 drives mounting plate 310 to rise and fall along slide rail 307. Slider 305 and slider 308 provide stable guidance for mounting plate 306 and mounting plate 310 respectively, realizing multi-dimensional precise positioning of processing head 313. Driver 311 starts, driving processing head 313 to rotate at high speed, and works with cutter 610 to perform full-process processing of workpiece, including turning, milling, drilling, boring, tapping, and cutting. All processing steps of complex workpieces can be completed in one clamping, avoiding the accumulation of errors caused by multiple clamping, greatly improving processing accuracy and production efficiency. During processing, cooling pipe 312 continuously sprays coolant to cool processing head 313, cutter 610 and workpiece in real time, preventing tool wear and workpiece thermal deformation caused by high temperature, and continuously ensuring stable processing quality.

[0081] If the cutting head 610 wears during the machining process, the controller 11 can control the driver 3 9 to start, drive the grinding disc 13 to rotate at high speed, and the tool assembly 5 adjusts the cutting head 610 to move to the machining position of the grinding disc 13, so as to realize online tool re-grinding without disassembling the tool, quickly restore the tool cutting accuracy, further stabilize the machining quality, and reduce downtime for tool change.

[0082] After processing is completed, the controller 11 controls all actuators to reset according to the preset program: cylinder 3 703 retracts, and fixing block 2 708 releases the workpiece; processing component 3, tool component 5, and adjustment component 4 return to their initial positions in sequence; the warning light 12 lights up green to indicate that processing is complete, the operator removes the finished workpiece, and the device re-enters standby mode, waiting for the next processing instruction. Throughout the entire operation of the vertical processing device, the controller 11 monitors the operating status of each component in real time. If a fault such as jamming, overload, or abnormal tool changing occurs, the warning light 12 immediately lights up red to remind the operator to handle it in time and ensure processing safety.

[0083] The integrated vertical machining unit achieves fully automated, high-precision, and high-efficiency operation through efficient collaboration of mechanical, pneumatic, and electric drives, perfectly matching the high-precision, high-efficiency, flexible, and automated production needs of modern manufacturing. At the same time, it eliminates the traditional bolt disassembly and assembly structure, reducing equipment failure frequency and maintenance costs, and extending the service life of the unit.
