Description

Technical Field

[0001] This invention relates to the field of machine tool processing technology, and in particular to a three-spindle, three-tool magazine linkage machining device. Background Technology

[0002] CNC machine tools are the main cutting equipment in modern machining, and machining centers are the most commonly used CNC machine tools. High-end manufacturing has an increasingly urgent need for multi-process, high-precision machining of complex parts. The collaborative technology of multi-spindle and multi-tool magazine is developing rapidly, and multi-spindle machining devices with three or more spindles are gradually becoming a research and development hotspot. With the precise tool changing linkage of multi-tool magazines, multiple processes such as milling, drilling, and boring can be completed in one clamping, which greatly shortens the machining process. At the same time, the upgrade of CNC systems and the progress of servo drive technology provide core support for the synchronous control of multi-spindle and multi-tool magazine, and promote the transformation of linkage machining technology towards "high speed, precision, and flexibility". When machining products, it is usually necessary to fix the workpiece to be machined on the worktable using a clamping device for product processing.

[0003] However, existing rigid clamping devices have a small contact area with the workpiece, resulting in concentrated pressure and easy indentation on the workpiece surface. At the same time, for irregularly shaped workpieces, traditional clamps are difficult to achieve full fit and fixation, and workpiece displacement is prone to occur during processing, affecting processing accuracy. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a three-spindle three-tool magazine linkage machining device, which effectively solves the problems of small contact area between the existing rigid clamping device and the workpiece, concentrated pressure, easy indentation on the workpiece surface, and difficulty in achieving full fit and fixation of irregular workpieces by traditional fixtures, which easily leads to workpiece displacement during the machining process and affects the machining accuracy.

[0017] like Figure 1-10 As shown, a three-spindle, three-tool magazine linkage machining device includes a base 3. A worktable 8 movable along the X and Y axes is provided on the base 3. A fixed frame 18 is fixedly installed on the worktable 8. Sliding frames 34, which are slidably connected to the worktable 8 and equidistantly adjustable, are respectively provided at both ends of the fixed frame 18. A first mounting plate 16 is fixedly provided at one end of the fixed frame 18 and the sliding frame 34, and a second mounting plate 17 is slidably provided at the other end of the fixed frame 18 and the sliding frame 34. Both the first mounting plate 16 and the second mounting plate 17 are provided with cylindrical components that can automatically adjust and fit according to the shape of the product. The cylindrical components include a first arc-shaped column 19 that is slidably connected to the inner wall of the first mounting plate 16 and the second mounting plate 17, respectively. A second arc-shaped column 20 is symmetrically slidably provided at both ends of the first arc-shaped column 19, and a third arc-shaped column 21 is symmetrically slidably provided at both ends of the second arc-shaped column 20.

[0018] In use, the device box 1 has a closing door 2 at its front end. The closing door 2 allows the product to be placed onto the worktable 8 of the device box 1. Rotating the fifth lead screw 31 at the lower end of the fixed frame 18 causes the fixed slider 29 to slide via the second screw 32. The fixed slider 29 causes the pin 35 at the end of the fixed rod 28 to slide along the inclined groove 27 of the sliding frame 34, driving the two sliding frames 34 to move equidistantly closer to or further away from the fixed frame 18, adapting to the overall spacing requirements of the product to be processed. The product is placed at the corresponding position between the fixed frame 18 and the sliding frame 34. Rotating each fourth lead screw 24 pushes the second mounting plate 17 closer to the first mounting plate 16. The first arc-shaped column 19, the second arc-shaped column 20, and the third arc-shaped column 21 of the cylindrical component automatically slide and adjust according to the product shape, layer by layer conforming to the product surface. The arc-shaped pin 22 enhances friction, achieving stable clamping, driving the worktable 8 to move along the X-axis or along the Y-axis. The axis movement precisely transfers the product to the processing area below the spindle mechanism. The spindle housing 14 moves up and down along the column 13 to adjust the processing height. The three spindle mechanisms start synchronously, and with the tool magazine 4 arranged in a horizontal and vertical staggered layout, the product is automatically changed to perform multi-process linkage processing.

[0019] One end of the sliding frame 34 and the fixed frame 18 are respectively fixedly connected to a rotating shaft block 25. The inner wall of the rotating shaft block 25 is fixedly connected to a first screw cylinder 26. The second mounting plate 17 is integrally rotatably provided with a fourth lead screw 24 that is threadedly engaged with the first screw cylinder 26. The two ends of the second mounting plate 17 are respectively fixedly provided with second limiting blocks 33 that are slidably connected to the inner walls of the fixed frame 18 and the sliding frame 34.

[0020] like Figure 8-10 As shown, a first rotating handle 23 is provided at one end of the fourth lead screw 24. The first rotating handle 23 drives the fourth lead screw 24 to rotate. By utilizing the threaded engagement relationship between the fourth lead screw 24 and the first screw cylinder 26 on the inner wall of the rotating shaft block 25, the rotational motion is converted into linear driving force, which in turn drives the integrally connected second mounting plate 17 to slide along the inner wall of the fixed frame 18 or the sliding frame 34, thereby adjusting the distance between the second mounting plate 17 and the first mounting plate 16. During the sliding process of the second mounting plate 17, the second limiting blocks 33 at both ends of the second mounting plate 17 precisely slide against the inner wall of the fixed frame 18 and the sliding frame 34, restricting the movement trajectory of the second mounting plate 17, avoiding deviation, and ensuring smooth and accurate sliding. By rotating the fourth lead screw 24 in both directions, the distance between the second mounting plate 17 and the first mounting plate 16 can be flexibly adjusted. With the help of the cylindrical components on both, the clamping and fixing of products to be processed of different sizes can be achieved, providing stable support for subsequent processing.

[0021] The lower end of the fixed frame 18 is rotatably connected to a fifth lead screw 31, and a fixed slider 29 is slidably connected to the fixed frame 18. The inner wall of the fixed slider 29 is fixedly connected to a second screw cylinder 32 that is threadedly engaged with the fifth lead screw 31. Fixed rods 28 are fixedly connected to both ends of the fixed slider 29, and pins 35 are provided at the ends of the fixed rods 28. The lower end of the sliding frame 34 is provided with a sloping groove 27 that is slidably connected to the pins 35. The two ends of the sliding frame 34 are respectively provided with first limiting blocks 36 that are slidably connected to the inner wall of the worktable 8.

[0022] like Figure 8-10 As shown, a second rotating handle 30 is provided at one end of the fifth lead screw 31. The fifth lead screw 31 is rotated by the second rotating handle 30, and through the threaded engagement with the second screw cylinder 32 on the inner wall of the fixed slider 29, the fixed slider 29 is driven to slide horizontally along the fixed frame 18. When the fixed slider 29 moves, it drives the fixed rods 28 at both ends to move synchronously. The pin 35 at the end of the fixed rod 28 slides in the inclined groove 27 at the lower end of the sliding frame 34. Using the guiding effect of the inclined groove 27, the sliding frame 34 is pushed to move horizontally along the inner wall of the worktable 8. During the movement of the sliding frame 34, the first limiting blocks 36 at both ends slide and engage with the inner wall of the worktable 8 to limit the movement direction of the sliding frame 34 and ensure its smooth and precise movement. By rotating the fifth lead screw 31 forward and backward, the sliding direction of the fixed slider 29 is controlled, thereby driving the two sliding frames 34 to move synchronously closer to or away from the fixed frame 18, realizing the equidistant adjustment of the distance between the fixed frame 18 and the sliding frame 34, and adapting to products of different sizes to be processed.

[0023] The first arc-shaped column 19, the second arc-shaped column 20, and the third arc-shaped column 21 are respectively provided with arc-shaped pins 22 at their arc-shaped ends.

[0024] like Figure 10 As shown, the arc-shaped pin 22 is adapted to each arc-shaped column, increasing the contact friction when it is in contact with the product surface to prevent the product from sliding; dispersing the fixing pressure to avoid indentation damage to the product surface; and in conjunction with the automatic adjustment function of the multiple arc-shaped columns, further improving the adaptability and fixing accuracy of products of different shapes.

[0025] An equipment box 1 is installed on the upper end of the base 3. A fixing plate 37 is fixedly installed on one end of the equipment box 1. Several spindle mechanisms are installed at equal intervals on the fixing plate 37. Each spindle mechanism includes a column 13, a spindle housing 14, and a tool magazine 4 for changing tools in the spindle housing 14. The column 13 is located on the rear side of the worktable 8. The spindle housing 14 is slidably connected to the front end of the column 13 and is located on the upper side of the worktable 8. A mounting top frame 38 is provided inside the equipment box 1. The rear end of the mounting top frame 38 is connected to the top of the column 13, and the front end of the mounting top frame 38 extends to the upper side of the worktable 8. The front end of the mounting top frame 38 is connected to the tool magazine 4.

[0026] like Figure 3 and 4 As shown, an equipment box 1 is installed on the upper end of the base 3. A fixing plate 37 is fixed to one end of the equipment box 1. Multiple spindle mechanisms are installed at equal intervals on the fixing plate 37. The column 13 of each spindle mechanism is vertically set on the rear side of the worktable 8. The spindle housing 14 is slidably connected to the front end of the column 13 and located above the worktable 8. The rear end of the top frame 38 is connected to the top of each column 13, and the front end extends to the top of the worktable 8 and fixes the tool magazine 4, thus completing the overall structural assembly. Multiple spindle mechanisms start synchronously and perform their respective processing operations. When a tool change is required, a frame 15 is installed at one end of the corresponding spindle housing 14. A cutting head is set at the lower end of the frame 15. By controlling the up and down movement of the spindle housing 14, the height and position of the cutting head at the lower end of the frame 15 are adjusted to precisely align with the tool magazine 4 at the front end of the top frame 38. After completing the automatic tool change, processing continues, realizing the linkage operation of multiple spindles and multiple tool magazines 4.

[0027] The column 13 is provided with a first drive assembly. The first drive assembly is connected to the spindle housing 14 and is used to drive the spindle housing 14 to move up and down. The first drive assembly includes a third motor 5 mounted on the column 13. A third lead screw 12 is mounted on the output end of the third motor 5. The third lead screw 12 drives the spindle housing 14 to move up and down through threaded transmission with the spindle housing 14.

[0028] like Figure 5 As shown, the third motor 5 is mounted on the column 13. The output end of the third motor 5 drives the third lead screw 12 to rotate. The third lead screw 12, through threaded engagement with the spindle housing 14, drives the spindle housing 14 to move up and down along the axis of the third lead screw 12, precisely adjusting the height position of the cutting head on the spindle housing 14 to adapt to processing requirements and tool changing actions.

[0029] The base 3 is provided with a second drive assembly, which includes a second motor 9. A second lead screw 10 is installed at the output end of the second motor 9. A support frame 6 is slidably connected to the upper end of the base 3. The second lead screw 10 drives the support frame 6 to reciprocate along the Y-axis by threadedly engaging with the support frame 6.

[0030] like Figure 6 As shown, the second motor 9 is mounted on the base 3. When the second motor 9 is working, the output end of the second motor 9 drives the second lead screw 10 to rotate. The second lead screw 10 drives the support frame 6 to slide back and forth along the axial direction of the second lead screw 10 through threaded engagement with the support frame 6.

[0031] The support frame 6 is provided with a first driving component, which includes a first motor 7. The output end of the first motor 7 is equipped with a first lead screw 11. The upper end of the support frame 6 is slidably connected to the worktable 8. The first lead screw 11 drives the worktable 8 to reciprocate along the X-axis by threadedly engaging with the worktable 8.

[0032] like Figure 7 As shown, the first motor 7 is mounted on the support frame 6. The output end of the first motor 7 drives the first lead screw 11 to rotate. During the rotation of the first lead screw 11, it drives the worktable 8 to move along the X-axis direction by threadedly engaging with the worktable 8.

[0033] The tool magazines 4 are respectively located on the front right, front middle and front left of the mounting top frame 38, and are arranged in a staggered horizontal and vertical layout.

[0034] like Figure 4 As shown, this avoids interference during tool changing in the four tool magazine compartments, improving space utilization and tool changing efficiency.

[0035] The working process of this invention is as follows: Rotating the fifth lead screw 31 drives the fixed slider 29 to move. The pin 35 at the end of the fixed rod 28 engages with the inclined groove 27 of the sliding frame 34, driving the sliding frame 34 to adjust at equal intervals to accommodate different spacing requirements. Rotating the fourth lead screw 24 pushes the second mounting plate 17 to slide, cooperating with the first mounting plate 16. The first arc-shaped column 19, the second arc-shaped column 20, and the third arc-shaped column 21 automatically and layer by layer adhere to the product surface, achieving stable clamping and effectively achieving full adhesion and fixation of the product. This avoids workpiece displacement during processing, improves processing accuracy, and the arc-shaped pin 22 enhances fixing stability. The first motor 7 drives the worktable 8 to move along the X-axis via the first lead screw 11, and the second motor 9 drives the support frame 6 (driving the worktable 8) along the Y-axis via the second lead screw 10, realizing the movement of the worktable 8 along the XY axis. Precise plane displacement is achieved by the third motor 5 driving the spindle housing 14 to move up and down along the column 13 via the third lead screw 12. The spindle housing 14 is equipped with a cutting head, which is used to process the product. Three tool magazines 4 are arranged in a staggered manner to change the cutting head on the corresponding spindle housing 14. Since the three spindle mechanisms work synchronously, multi-process linkage processing is performed on the product fixed on the worktable 8. After processing is completed, there is no need to stop the equipment. The processing position can be switched by moving the worktable 8, or the product can be changed by adjusting the sliding frame 34 and the second mounting plate 17, so as to achieve continuous and efficient processing.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
