Description

Technical Field

[0001] This invention relates to the field of multi-station machine tool technology, and more particularly to the connection structure of multi-station machining centers in gantry machining centers. Background Technology

[0002] A gantry machining center is a large CNC metal cutting machine. Its main body consists of a gantry frame, crossbeam, slide, and worktable. It is commonly used for milling, drilling, and boring of large sheet metal and box-shaped workpieces. It features a large machining range and high precision. Multi-station operation means that the added structure includes two or more independent machining stations, each capable of independently clamping a workpiece. Switching between stations is achieved through mechanical transmission, such as guide rail translation or turntable rotation. The aim is to enable parallel machining and clamping operations. While a workpiece is being machined at one station, the operator can clamp and unclamp the workpiece at another station, significantly reducing downtime and improving machining efficiency. The multi-station gantry machining center, with its added multi-station worktable and mechanism, requires a dedicated connecting structure to simultaneously meet structural rigidity, positioning accuracy, and reliable station switching. Gantry machining centers are often used for cutting large and heavy workpieces, generating significant cutting forces and vibrations during the machining process. Multi-station machining centers carry multiple workpieces and fixtures. Without a stable connection structure, gaps or insufficient rigidity may occur between the machining center, the main machine bed, and the original worktable. This can lead to excessive surface roughness, dimensional inaccuracies, and even tool breakage. As the manufacturing industry upgrades towards high precision, high efficiency, and large scale, the demand for machining complex parts in the automotive, aerospace, and precision instrument industries is increasing, placing higher demands on the comprehensive performance of machining equipment.

[0003] The existing processing equipment suffers from low single-station processing efficiency. Traditional gantry machining centers are mostly single-station operations, processing only one workpiece at a time. Multiple clamping and adjustments are required to complete multiple processes such as milling, drilling, and grinding, resulting in lengthy production cycles and difficulty in meeting the demands of large-scale production. Workpiece clamping operations are cumbersome. Existing equipment lacks efficient limiting structures, requiring repeated calibration of the position when manually installing workpieces. This not only increases operational difficulty and labor intensity but also easily affects clamping accuracy due to positioning deviations, leading to processing errors. There are shortcomings in multi-process integration. Most processing equipment cannot integrate multiple processing steps at the same station, requiring frequent transfer of workpieces between different equipment or stations. This not only increases the cost of semi-finished product turnover management but may also affect product quality consistency due to bumps and positioning deviations during transfer. Finally, equipment compatibility is insufficient. Traditional multi-station equipment is mostly designed for specific workpiece specifications, with poor flexibility in limiting and connecting structures, making it difficult to adapt to the processing needs of workpieces of different sizes and shapes, thus reducing the efficiency of the processing equipment.

[0004] To address the aforementioned issues, a multi-station machining center connection structure is proposed for gantry machining centers. Summary of the Invention

[0033] Working Principle: Firstly, during the start-up and preparation phase of the processing equipment, the operator starts the equipment via controller 22 on the right side of the bed 1. Controller 22 presets processing parameters, including the processing technology of each station, tool running speed, clamping force, and station switching time. Simultaneously, the cooler 4 begins preheating, the chip conveyor 3 enters standby mode, and the opening / closing door 21 is in the open position for easy workpiece clamping. Base 1 2 and Base 2 6 ensure the bed 1 and cooler 4 are stably placed to prevent shaking during processing, providing a basic guarantee for subsequent processing accuracy. Maintenance components need to be checked in advance during this phase: whether the chip collection box of the chip conveyor 3 is empty, whether the liquid level in the cooler 4 is up to standard, and whether the lubrication of each moving component is good, ensuring stable operation after equipment start-up. Then, during the workpiece clamping and limiting phase, the operator… The operator places the workpiece to be processed on the workpiece plate 901 of the clamping assembly 9. According to the size and shape of the workpiece, the operator rotates the handle 908 to drive the threaded rod 906 to rotate. Since the threaded rod 906 is threadedly connected to the first threaded block 904 and the second threaded block 905, and the first threaded block 904 and the second threaded block 905 are confined within the slide groove 907, the rotation of the threaded rod 906 is converted into the linear movement of the threaded blocks. The distance between the first threaded block 904 and the second threaded block 905 is adjusted to initially clamp the workpiece. Then the limiting assembly 8 is activated. The second cylinder 801 receives the signal from the controller 22 and pushes the connecting plate 802 downward. The connecting plate 802 drives the second connecting block 805 to move. Through the linkage between the rotating rod 804 and the second mounting block 803, the pressure block 806 is pressed towards the workpiece to complete the precise limiting.During this process, the telescopic rod 808 and spring 809 act as a buffer to prevent excessive pressure from the pressure block 806 from damaging the workpiece, while ensuring uniform clamping force. At this stage, the limiting structure of the workpiece plate 901 and the synergistic action of the limiting component 8 provide auxiliary positioning during workpiece clamping, facilitating manual workpiece clamping, quickly completing workpiece positioning calibration, reducing manual adjustment time, avoiding positioning deviations, and ensuring machining accuracy. Maintenance components require attention to whether the contact surface of the pressure block 806 is flat and whether the sliding between the threaded block and the slide groove 907 is smooth. If wear or jamming occurs, it should be addressed promptly to ensure clamping accuracy. Secondly, during the station switching and rotation adjustment stages, the workpiece clamping... After completion, the operator closes the opening and closing door 21, the controller 22 sends a workstation switching signal, the moving component 5 starts, the cylinder 501 outputs power, pushing the slider 502 to slide along the slide rail 503. The slider 502 drives the upper rotating component 7, the limiting component 8 and the clamping component 9 to move as a whole through the mounting block 504 and the connecting block 505, accurately transporting the workpiece to the target processing station. If the workpiece needs to be processed on multiple sides, the rotating component 7 starts to work, the motor 702 starts to drive the drive gear 703 to rotate, the drive gear 703 meshes with multiple driven gears 704, driving the driven gears 704 to rotate in the gear ring 705, and then driving the rotating column 707 to rotate, realizing the 360-degree rotation adjustment of the workpiece. The connecting column 706 provides protection and support for the gear transmission structure, ensuring that the transmission process is smooth and accurate, so that the workpiece can be processed on multiple sides without re-clamping, greatly shortening the production cycle.

[0034] Simultaneously, multiple processing stages can be performed. After the workpiece reaches the target station and is adjusted to a suitable angle, each processing component starts to perform multi-process processing. The moving axis 11 on the right side of the inner wall of the bed 1 drives the grinding wheel 12 to move and grind the workpiece. The moving axis 14 on the left side drives the drill 15 to perform drilling operations. The drive motor 23 on the rear left end drives the rotary axis 16 to cooperate with the cutting tool 17 for cutting operations. Then the milling tool 18 completes the milling operation. Multiple coolers 19 on the inner wall of the milling tool 18 cool down in real time to avoid the processing area temperature from being too high and damaging the tool and workpiece. During the processing, the chip conveyor 3 works continuously to quickly discharge metal chips. The cooler 4 continuously delivers coolant to reduce the processing temperature and ensure processing accuracy and tool life. Thus, a single station integrates multiple processing operations such as milling, drilling, and grinding. Multiple workpieces can be processed in parallel at different stations. Compared with traditional single-station equipment, the processing efficiency is significantly improved, meeting the needs of large-scale batch production.

[0035] During the processing completion and reset phase, after all processing steps are completed, each processing component resets. The cooler 4 and chip conveyor 3 continue operating for a period to ensure the processing area is clean and the temperature drops to a safe range. Then, the moving component 5 moves the workpiece back to its initial position, the cylinder 801 of the limit component 8 retracts, the pressure block 806 releases, and the operator rotates the handle 908 to release the clamping component 9, opening the opening and closing door 21 to remove the finished workpiece. Finally, the controller 22 sends a signal, all components of the equipment reset, and the machine enters standby mode, awaiting the next batch of workpieces for processing. During this phase, the maintenance component needs to perform a final inspection, cleaning debris from the surface and interior of the equipment, checking the wear of each moving part, replenishing lubricating oil, and replacing worn parts. To ensure the equipment can operate normally upon next startup, during the entire operation, all components are precisely linked through controller 22. Moving component 5 ensures precise and efficient switching between workstations, rotating component 7 enables multi-faceted machining of workpieces, limiting component 8 and clamping component 9 ensure accurate workpiece positioning and firm clamping, and the machining parts complete multi-process integrated machining. Chip removal and cooling components ensure a stable machining environment. Through regular inspection, cleaning, and replacement of parts, the rigidity of the equipment structure, positioning accuracy, and operational stability are ensured. This effectively solves the problems of low efficiency of single workstations, multiple clamping for multiple processes, cumbersome workpiece clamping and easy deviation, poor connection between multiple processes, and insufficient equipment compatibility in traditional gantry machining centers, achieving high-precision, high-efficiency, and large-scale machining.
