Description

Technical Field

[0001] This utility model relates to the field of milling technology, and more specifically to a tooling for rapid milling. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system, which can make the machine tool move and process parts according to a preset program.

[0003] Currently, when milling on CNC machine tools, conventional workpieces are typically clamped using traditional methods such as vises and chucks, or specialized tooling designed for specific product types for rapid clamping. However, when dealing with large cast or forged blanks with varying dimensions and shapes, traditional clamping methods are not flexible and efficient. Due to individual differences between each blank—for example, when clamping a marine diesel engine bearing housing on a milling machine—tools such as jacks, height gauges, and pressure plates are often needed to adjust the workpiece to ensure proper clamping and meet the requirements of the machining program. This adjustment process is not only time-consuming, but also keeps the milling machine in a standby state, unable to perform actual machining tasks, thus indirectly reducing overall production efficiency. Utility Model Content

[0004] The present invention aims to provide a tooling for rapid milling, which improves the speed and accuracy of clamping large cast and forged blanks and increases their production efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tooling for rapid milling, comprising a pallet body for supporting a workpiece, wherein the top of the pallet body is provided with a plurality of positioning mechanisms for circumferentially positioning the workpiece centerline and a plurality of clamping mechanisms for clamping the workpiece, and the bottom of the pallet body is provided with a plurality of fixing mechanisms for fixing the position of the pallet body; the positioning mechanism includes a center positioning component for positioning the workpiece centerline, the center positioning component being located on the centerline of the pallet body and contacting the side of the workpiece; the clamping mechanism is located on the left and right sides of the vertical centerline of the pallet body, the clamping mechanism including positioning... The pallet body has a height equalization block located on its top surface. Above the height equalization block is a detachable pressure plate and a first screw penetrating the pressure plate. The pressure plate is connected to the pallet body via the first screw. The space between the pressure plate and the pallet body is used to place a workpiece. By adjusting the height of the first screw, the distance between the pressure plate and the pallet body can be adjusted, allowing the pressure plate to move downwards and press the workpiece. The bottom surface of the pressure plate is in close contact with the upper surface of the workpiece, and the top surface of the pallet body is in close contact with the lower surface of the workpiece. The fixing mechanism is located around the pallet body and is used to fix the pallet body to the worktable of the milling machine tool.

[0006] The principle of this solution is as follows: In practical application, a crane is used to transport the workpiece to be processed onto the pallet body, and the center line of the workpiece is aligned using a center positioning component. After the center line of the workpiece is aligned, a first screw is used to pass through the connection between the pressure plate and the pallet body. By tightening the first screw, sufficient pressure is applied to the pressure plate, causing it to move downwards and press the workpiece firmly onto the pallet body. At this time, the bottom surface of the pressure plate is in close contact with the upper end surface of the workpiece, and the top surface of the pallet body is in close contact with the lower end surface of the workpiece, ensuring that the workpiece is clamped. After the workpiece is clamped, a crane is used to smoothly move the entire pallet body onto the worktable of the milling machine, and the entire pallet body is fixedly installed on the worktable of the milling machine using a fixing mechanism, thereby performing milling processing on the workpiece.

[0007] The advantages of this solution are: (1) Compared with the existing technology of moving the workpiece to the CNC machine tool and then clamping it, this solution adopts the method of clamping the workpiece on the pallet body first and then moving it to the machine tool for processing, which not only ensures the clamping quality but also improves the work efficiency. At the same time, it breaks the technical prejudice that clamping large workpieces occupies the machine tool processing time and realizes the separation of clamping and processing.

[0008] (2) This solution moves the clamped workpiece to the machine tool table for processing, reducing the preparation time of the workpiece on the machine tool and enabling the machine tool to enter the processing state more quickly.

[0009] (3) Improve machining accuracy by aligning the center line of the workpiece and using a sturdy clamping plate, and ensure the stability and consistency of each workpiece clamping.

[0010] (4) Fixed assembly points and mechanical structures (i.e., the actual center positioning components and clamping mechanisms in this scheme) reduce errors caused by human factors and ensure consistency and reliability of each installation.

[0011] Preferably, as an improvement, the center positioning assembly includes a pin for aligning the workpiece centerline and a center positioning block for supporting the pin, the tip of the pin passing through the center positioning block and extending to contact the side of the workpiece.

[0012] Beneficial effects: The tip of the ejector pin contacts the side of the workpiece, enabling precise alignment with the workpiece's centerline and achieving high-precision centerline calibration. This improves the accuracy of the workpiece position and ensures the precision of subsequent milling operations. The center positioning block provides stable support for the ejector pin, preventing it from shifting or wobbling during workpiece adjustment and further enhancing the reliability of the calibration process.

[0013] Preferably, as an improvement, the center positioning component includes a first center positioning component and a second center positioning component; the first center positioning component is located on the left and right sides of the pallet body and is symmetrically distributed along the vertical center line of the pallet body; the second center positioning component is located on the vertical center line of the pallet body and is used to align the center line of the workpiece.

[0014] Beneficial effects: By combining the first center positioning components on both sides with the second center positioning component in the middle, dual alignment is provided to ensure that the center line of the workpiece can be accurately found and calibrated. The first center positioning component balances the force on the left and right sides of the workpiece during clamping, reducing errors caused by asymmetrical pressure. The second center positioning component can effectively prevent longitudinal displacement of the workpiece during processing, further improving positioning accuracy and processing stability.

[0015] Preferably, as an improvement, a shim is provided between the leveling block and the pressure plate, the shim being used to adjust the height and level of the pressure plate.

[0016] Beneficial effects: Shims allow the workpiece to be accurately adjusted to the required processing height, ensuring consistency during the processing. At the same time, by adjusting the thickness of the shims, the pressure plate can be kept level, thereby applying pressure evenly to the workpiece and avoiding uneven pressure caused by the tilt of the pressure plate, which would affect the processing quality.

[0017] Preferably, as an improvement, the positioning mechanism further includes an adjustment component, which includes an adjustment block and a first adjustment bolt; the adjustment block is located at the front end of the pallet body, and the adjustment block is provided with a screw hole for the first adjustment bolt to pass through. One end of the first adjustment bolt after passing through the screw hole abuts against the front side of the workpiece, and rotating the first adjustment bolt can adjust the length of the protruding part of the first adjustment bolt.

[0018] Beneficial effects: The first adjusting bolt is tightened against the front side of the workpiece, providing an additional support point for the workpiece, making it less likely to shift in the longitudinal direction and enhancing the stability of the workpiece.

[0019] Preferably, as an improvement, the adjustment assembly further includes a jack, which is bolted to the top surface of the pallet body and located behind the adjustment block, for adjusting the vertical height of the workpiece.

[0020] Beneficial effects: The jack provides strong vertical support for the workpiece. When handling large workpieces, it can ensure that the workpiece remains stable throughout the entire processing, avoiding positional displacement caused by vibration or uneven pressure. At the same time, it can be flexibly adjusted according to the height requirements of the workpiece.

[0021] Preferably, as an improvement, the pressure plate is hollow in shape, and the hollow shape is elongated.

[0022] Beneficial effects: The hollow design makes it easy to fix the first screw and speeds up the clamping process. At the same time, it makes the workpiece part under the pressure plate visible, which is convenient for operators to check the status of the workpiece or make necessary adjustments without having to completely remove the pressure plate.

[0023] Preferably, as an improvement, the fixing mechanism includes a fixing component, a second screw, and a tray base. The fixing component has a through hole for the second screw to pass through, and the second screw passes through the through hole to mount the tray base and the tray body onto the machine tool worktable.

[0024] Beneficial effects: The second screw, in conjunction with the through hole on the fixing component, allows the pallet base to be quickly and easily installed onto the machine tool table, and is also easy to disassemble, greatly reducing preparation time. At the same time, the second screw enhances the stability and accuracy between the pallet base, the pallet body, and the machine tool table.

[0025] Preferably, as an improvement, the fixing component includes a first positioning block and a second positioning block, wherein the first positioning block is embedded in the second positioning block to position and connect the pallet base and the pallet body.

[0026] Beneficial effects: The design of the first positioning block being embedded in the second positioning block ensures that the relative position between the pallet base and the pallet body can be precisely controlled, reducing clamping errors and improving processing accuracy. At the same time, it prevents the pallet body and pallet base from loosening or shifting during processing, enhancing the stability of the entire tooling and ensuring processing quality.

[0027] Preferably, as an improvement, the spacing between adjacent pressing mechanisms on the same side is 350mm-730mm.

[0028] Beneficial effects: Appropriate spacing can ensure that the workpiece is subjected to uniform pressure distribution during the clamping process, avoiding deformation or processing errors caused by excessive or insufficient local pressure, and improving processing accuracy.

[0029] The beneficial effects of this solution are: (1) The design of the positioning mechanism, clamping mechanism, fixing mechanism and screw (i.e., the first adjusting bolt, the second adjusting bolt, the first screw and the second screw) is easy to operate, simplifies the installation and disassembly process of the workpiece, reduces preparation time and improves production efficiency.

[0030] (2) The various mechanisms (i.e., positioning mechanism, clamping mechanism, fixing mechanism) are stably connected and accurately positioned, preventing the workpiece from loosening or shifting during the processing, enhancing the stability of the entire system, and ensuring the processing quality.

[0031] (3) The tooling design of this scheme ensures that the same effect is achieved every time the clamping is performed, guarantees the accuracy and stability of each clamping process, and achieves highly consistent clamping results.

[0032] (3) This solution supports parallel operation, that is, while a workpiece is clamped on one pallet body, a workpiece on another pallet body can be processed on a milling machine, realizing the parallelization of clamping and processing, and further improving production efficiency.

[0040] Figure 8 for Figure 4 A partial sectional view of section I. Detailed Implementation

[0041] The following detailed description illustrates the specific implementation method:

[0042] The reference numerals in the accompanying drawings include: tray body 1, adjusting block 2, first adjusting bolt 3, tray base 4, leveling block 5, first center positioning block 6, first ejector pin 7, pressure plate 8, second center positioning block 9, jack 10, first screw 11, second adjusting bolt 12, first positioning block 13, second positioning block 14, second screw 15, workpiece 16, milling machine tool 17.

[0043] Example 1:

[0044] The implementation examples are basically as follows Figure 1 As shown: A tooling for rapid milling includes a pallet body 1 for supporting a workpiece 16. The top of the pallet body 1 is equipped with a plurality of positioning mechanisms for circumferentially positioning the center line of the workpiece and a plurality of clamping mechanisms for clamping the workpiece 16. The bottom of the pallet body 1 is equipped with a plurality of fixing mechanisms for fixing the position of the pallet body 1. The positioning mechanism includes a central positioning component located on the center line of the pallet body 1, used to contact the side of the workpiece 16 and position the center line of the workpiece 16. The clamping mechanism is located on the left and right sides of the pallet body 1 and is symmetrically distributed about the vertical center line of the pallet body 1. The clamping mechanism includes a leveling block 5 for positioning, located on the top surface of the pallet body 1. Above the leveling block 5 is a detachable pressure plate 8 and a first screw 11 passing through the pressure plate 8. The first screw 11 passes through the pressure plate 8 and is connected to the pallet body 1. The workpiece 16 is placed between the pressure plate 8 and the pallet body 1. By adjusting the height of the first screw 11, the distance between the pressure plate 8 and the pallet body 1 can be adjusted so that the pressure plate 8 moves downward to clamp the workpiece 16. The bottom surface of the pressure plate 8 is in close contact with the upper end surface of the workpiece 16, and the top surface of the pallet body 1 is in close contact with the lower end surface of the workpiece 16. The fixing mechanism is located at the corners of the pallet body 1 and is used to fix the pallet body 1 on the milling machine table for milling processing, thereby improving the production efficiency of the workpiece 16. In this embodiment, the machine tool used is a CNC milling machine, or simply milling machine 17. For example... Figure 2 As shown, workpiece 16 is a bearing housing for a marine diesel engine, and its size and shape are very complex.

[0045] Specifically, the pallet body 1 is welded together from five T40 thick steel plates, which ensures the necessary structural strength while making efficient use of materials and reducing the overall weight of the pallet. The welding technology ensures a firm connection between the steel plates. The pallet body 1 is provided with several positioning holes according to the requirements of the workpiece 16. Through the positioning holes, the positioning mechanism, the clamping mechanism, and the fixing mechanism can be accurately installed into the designated positions on the pallet body 1.

[0046] The positioning mechanism includes a central positioning component and an adjustment component. The central positioning component includes a ejector pin for aligning the center line of workpiece 16 and a central positioning block for supporting the ejector pin. The central positioning block is located on the top surface of the tray body 1 and is fixedly connected to the tray body 1. The central positioning block has a through hole for the ejector pin to pass through. The tip of the ejector pin passes through the through hole on the central positioning block and extends to directly contact the side of the center line of workpiece 16, ensuring accurate positioning of workpiece 16. In this embodiment, the central positioning component includes a first central positioning component and a second central positioning component. Specifically, the central positioning block includes a first central positioning block 6 and a second central positioning block 9, and the ejector pin includes a first ejector pin 7 and a second ejector pin. The first central positioning component is composed of the first central positioning block 6 and the first ejector pin 7. The first central positioning component is located on the left and right sides of the tray body 1 and is symmetrically distributed along the vertical center line of the tray body 1. The tip of the first ejector pin 7 passes through the through hole on the first central positioning block 6 and extends to directly contact the horizontal center line of workpiece 16, enabling accurate alignment of the center lines on the left and right sides of workpiece 16. Meanwhile, the symmetrically distributed first center positioning components can evenly distribute the force, avoiding deformation or displacement of the workpiece 16 due to uneven force, thus enhancing the stability of the machining process. The second center positioning component consists of a second center positioning block 9 and a second ejector pin. The second center positioning component is located on the vertical center line of the tray body 1. The tip of the second ejector pin passes through the through hole on the second center positioning block 9 and extends to directly contact the vertical center line of the workpiece 16, enabling precise alignment of the workpiece center. In this solution, the center line of the workpiece 16 is aligned using ejector pins, ensuring the accuracy of the workpiece 16's position during clamping, thereby improving machining accuracy and product quality. Furthermore, using independent center positioning components (i.e., the first and second center positioning components) to handle the alignment of the transverse and longitudinal center lines respectively makes the adjustment process simpler and more direct, reducing debugging time and difficulty.

[0047] like Figure 3 , Figure 4As shown, the adjustment assembly includes an adjustment block 2, a jack 10, a first adjusting bolt 3, and a second adjusting bolt 12. The adjustment block 2 is located on the front side of the pallet body 1. The adjustment block 2 has a screw hole through which the first adjusting bolt 3 passes. One end of the first adjusting bolt 3, after passing through the screw hole, is pressed against the front side of the workpiece 16. Rotating the first adjusting bolt 3 adjusts the length of its protruding portion, thereby adjusting the position of the workpiece 16. The jack 10 is bolted to the top surface of the pallet body 1, located behind the adjustment block 2, and is used to adjust the vertical height of the workpiece 16, ensuring that the pressure plate 8 can more accurately cover the workpiece 16, thus improving the clamping effect of the tooling. The second adjusting bolt 12 is installed on the pallet body 1 through a positioning hole. The second adjusting bolt 12 consists of a screw and a nut, with the nut welded and fixed to the screw. Adjusting the nut adjusts the position of the screw, thereby enabling the second adjusting bolt 12 to move vertically, thus precisely adjusting the height of the workpiece 16, ensuring that the workpiece 16 can be accurately positioned as required. In this embodiment, two adjusting blocks 2 are installed and symmetrically distributed along the vertical centerline of the tray body 1.

[0048] The clamping mechanisms are located on the left and right sides of the pallet body 1 and are evenly and symmetrically distributed along the vertical center line of the pallet body 1. Each clamping mechanism includes a height equalizing block 5 and a detachable pressure plate 8. The height equalizing block 5 is installed on the top surface of the pallet body 1. The pressure plate 8 is installed above the height equalizing block 5 via a first screw 11 and a nut. The first screw 11 passes through the pressure plate 8 and connects to the pallet body 1. The space between the pressure plate 8 and the pallet body 1 is used to place the workpiece 16. By adjusting the height of the first screw 11, the distance between the pressure plate 8 and the pallet body 1 can be adjusted, causing the pressure plate 8 to move downwards and clamp the workpiece 16, ensuring close contact between the bottom surface of the pressure plate 8 and the upper surface of the workpiece 16, and close contact between the top surface of the pallet body 1 and the lower surface of the workpiece 16. In this embodiment, six clamping mechanisms are provided on the pallet body 1, evenly distributed on both sides of the vertical center line. Specifically, each side has three clamping mechanisms, and the spacing between adjacent clamping mechanisms on the same side is 350mm-730mm, ensuring that the workpiece 16 can be evenly and securely fixed on the pallet body 1. In this embodiment, a first pressing mechanism, a second pressing mechanism, and a third pressing mechanism are arranged sequentially from top to bottom on the right side of the pallet body 1. The distance between the first pressing mechanism and the second pressing mechanism is 400mm, and the distance between the second pressing mechanism and the third pressing mechanism is 730mm. This ensures that the workpiece 16 is subjected to uniform pressure distribution during the pressing process, avoiding deformation or processing errors caused by excessive or insufficient local pressure, thereby improving processing accuracy.

[0049] In this embodiment, the pressure plate 8 is a hollow rectangle, and the hollow part is elongated. For example, as... Figure 5As shown, in this embodiment, the hollow shape is elliptical, which not only facilitates fixing the first screw 11 and speeds up the clamping process, but also makes the workpiece 16 part below the pressure plate 8 visible. This allows the operator to easily check the status of the workpiece 16 or make necessary adjustments without completely removing the pressure plate 8, thereby improving work efficiency and enhancing the convenience and flexibility of operation.

[0050] The fixing mechanism is located around the pallet body 1 and includes a fixing component and a pallet base 4. The fixing component is used to precisely position and connect the pallet base 4 to the pallet body 1, ensuring that the two maintain an accurate relative position. A second screw 15 passes through the fixing component and engages with a nut to securely mount the pallet body 1 together with the pallet base 4 onto the worktable of the milling machine tool 17. The fixing mechanism ensures that the workpiece 16 can be accurately and precisely mounted on the milling machine tool 17 during machining, providing a precise basis for CNC operation, thereby improving the machining accuracy of the workpiece 16 and the overall production efficiency. In this embodiment, four fixing mechanisms are used and evenly distributed around the pallet body 1.

[0051] The specific implementation process of this embodiment is as follows:

[0052] 1. Before processing: Place workpiece 16 on pallet body 1 for clamping. Use a crane to move workpiece 16 onto pallet body 1, aligning its centerline with the first center positioning block 6 and the second center positioning block 9. Then, the tip of the first ejector pin 7 passes through the first center positioning block 6, and the tip of the second ejector pin passes through the second center positioning block 9 to calibrate the centerline of workpiece 16. Adjustments can be made to workpiece 16 using jack 10, first adjusting bolt 3, and second adjusting bolt 12 to ensure the ejector pin tips are more precisely aligned with the centerline. Specifically, workpiece 16 is placed stably on top of jack 10. By adjusting the height of the bolt passing through jack 10, the position of workpiece 16 can be fine-tuned to ensure it reaches the required correct height. The first adjusting bolt 3 works in conjunction with adjusting block 2 to press against the front end of workpiece 16, ensuring it remains stable during adjustment and does not shift. The second adjusting bolt 12 is used to adjust the height of workpiece 16, ensuring its accuracy. Throughout the adjustment process, the position of the ejector pin aligned with the center line is measured using a height gauge to confirm whether the adjustment of the jack 10, the first adjusting bolt 3, and the second adjusting screw ensures that the ejector pin is at the same center height as the workpiece 16.

[0053] After the centerline of workpiece 16 is aligned, the first screw 11 passes through the pressure plate 8 and engages with the nut to drive the pressure plate 8 downward to clamp workpiece 16. At this time, the bottom surface of the pressure plate 8 is in close contact with the upper end surface of workpiece 16, and the top surface of the tray body 1 is in close contact with the lower end surface of workpiece 16. Specifically, by tightening the first screw 11, sufficient pressure is applied to the pressure plate 8 to firmly fix workpiece 16 onto the tray body 1.

[0054] After workpiece 16 is clamped, as follows Figure 6 As shown, the pallet body 1 is smoothly moved to the worktable of the milling machine tool 17 using a crane. According to the positioning dimensions of the pallet body 1, it is ensured to be accurately aligned and placed on the pre-installed pallet base 4 on the worktable of the machine tool. Then, the pallet body 1 and the pallet base 4 are assembled using a fixing component, and the second screw 15 is used to pass through the pallet body 1 and be fixed with a nut, so that the tooling is stably installed on the worktable of the milling machine tool.

[0055] 2. During machining: Before the actual machining, a tool setting step is performed before the program runs, and then the CNC machine tool is started to perform milling machining.

[0056] Compared to existing technologies that involve transferring workpiece 16 to a CNC machine tool for clamping, this solution employs a method where workpiece 16 is first clamped on the pallet body 1 before being transferred as a whole to the milling machine 17 for processing. This approach ensures both clamping quality and improved work efficiency. It breaks the technical bias that clamping large workpieces 16 occupies processing time on the milling machine 17, achieving separation of clamping and processing. This solution significantly improves processing accuracy and ensures the consistency of each workpiece 16 by using the workpiece 16's centerline for positioning and clamping with the pressure plate 8. This ensures consistent results for each clamping operation, guaranteeing accuracy and stability in every clamping process. Specifically, (1) by utilizing the ejector pin, center positioning block, jack 10, first adjusting bolt 3 and second adjusting bolt 12 together, the center height and position of workpiece 16 can be precisely controlled, ensuring that the tip of the ejector pin can be accurately aligned with the center line of workpiece 16, and that the clamping effect of workpiece 16 is consistent each time; (2) the pressure plate 8 applies downward pressure to workpiece 16, the adjusting block 2 provides lateral support force by tightly connecting with the side of workpiece 16, and the tray body 1 provides stable upward support force for workpiece 16. The three work together to effectively prevent workpiece 16 from moving or deforming during processing, ensuring the stability and firmness of workpiece 16 throughout the entire processing process, thereby guaranteeing the processing quality. (3) The connection and usage of each mechanism (i.e., positioning mechanism, clamping mechanism, fixing mechanism) and screws (i.e., first adjusting bolt 3, second adjusting bolt 12, first screw 11, second screw 15) simplify the operation process and reduce preparation time.

[0057] Example 2:

[0058] The difference between this embodiment and Embodiment 1 is that the adjusting block 2 has an "L-shaped" structure, including a vertically extending vertical rod and a horizontally extending horizontal rod from the vertical rod.

[0059] Specifically, such as Figure 7 As shown, the vertical rod is equivalent to the vertical part of the "L-shape", and the horizontal rod is equivalent to the horizontal part of the "L-shape". The vertical rod is installed on the pallet body 1 and the horizontal rod is perpendicular to the pallet body 1. The horizontal rod is provided with a screw hole for the first adjusting bolt 3 to pass through. The screw hole through which the first adjusting bolt 3 passes is in contact with the front side of the workpiece 16, thereby facilitating the subsequent position adjustment of the workpiece 16.

[0060] Example 3:

[0061] The difference between this embodiment and embodiment one is that shims can be filled between the equal height block 5 and the pressure plate 8 to adjust the height of the workpiece 16, thereby facilitating the pressing of the pressure plate 8.

[0062] Specifically, after the center line of workpiece 16 is aligned, in order to ensure that the pressure plate 8 can press the workpiece 16 horizontally and tightly, the height of the pressure plate 8 can be adjusted by adding shims of appropriate thickness between the equalizing block 5 and the pressure plate 8, so that the pressure plate 8 remains horizontal and matches the height of the workpiece 16. Thus, the pressure plate 8 can apply force evenly and press the workpiece 16 tightly, thereby improving the accuracy of tooling clamping.

[0063] Example 4:

[0064] The difference between this embodiment and embodiment one is that the fixing component includes a first positioning block 13 and a second positioning block 14, wherein the first positioning block 13 is embedded inside the second positioning block 14, thereby positioning and connecting the pallet base 4 and the pallet body 1.

[0065] Specifically, such as Figure 8 As shown, the crane smoothly moves the pallet body 1 onto the machine tool worktable. Based on the positioning dimensions of the pallet body 1, it is precisely aligned and placed on the pre-installed pallet base 4 on the worktable of the milling machine 17. Subsequently, the first positioning block 13 is embedded into the second positioning block 14 to assemble the pallet body 1 and the pallet base 4. Then, the second screw 15 passes through the first positioning block 13 and the second positioning block 14, engaging with an M24 nut to install the entire fixture onto the machine tool worktable.

[0066] Example 5:

[0067] The difference between this embodiment and Embodiment 1 is that multiple pallet bodies 1 can be used simultaneously.

[0068] Specifically, in this embodiment, two pallet bodies 1 are used. While the milling machine 17 is running the CNC program to process the first workpiece, the operator can clamp the second workpiece on an independent clamping platform. After the first workpiece is processed, the pallet body 1 of the clamped second workpiece is immediately transported to the worktable of the milling machine 17 and assembled with the pallet base 4 for milling.

[0069] This solution effectively utilizes the downtime during CNC program execution, avoiding equipment downtime caused by workpiece clamping on the milling machine 17's worktable. This not only ensures the continuity of the machining process but also maximizes the utilization of the milling machine 17's working time and resources, thereby significantly improving overall production efficiency.
