Description

Technical Field

[0001] This invention relates to the field of machining center technology, and more particularly to a vertical milling and turning composite machining center with a power tool holder. Background Technology

[0002] Vertical milling and turning machining centers are advanced CNC machine tools that integrate milling and turning functions. They feature high precision, high efficiency, and multiple functions, and are widely used in the machining of high-precision, complex-shaped parts in aerospace, automobile manufacturing, mold processing, and other fields. They can be equipped with a variety of special tools, reducing tool change time, and have a compact and beautiful appearance, improving space utilization.

[0003] A search revealed Chinese patent CN113814733A, which discloses a vertical turning-milling machining center. The center includes a controller, a base, a rotary table, a horizontal moving mechanism, a first lifting mechanism, a second lifting mechanism, a gantry, a vertical spindle box, a turning-milling spindle unit, and a vertical tool magazine. The vertical spindle box is vertically mounted on a first saddle via the first lifting mechanism to process the workpiece on the rotary table. The turning-milling spindle unit is vertically mounted on a second saddle via the second lifting mechanism to perform turning, milling, and cutting operations on the workpiece on the rotary table. The rotary table includes a worktable, a turntable, a fixed base, a drive mechanism, a hydraulic cylinder, a brake ring, and a brake disc. This solution addresses the problems of limited machining capabilities and insufficient precision in rotary table braking affecting workpiece machining accuracy in existing machine tools. However, in practical use, this solution still has the following shortcomings:

[0004] Typically, to securely clamp metal workpieces of various sizes and shapes, specially designed fixtures are installed in specific slots on the machine tool. The slots provide a track structure that allows the fixture to slide flexibly left and right, facilitating position adjustments. However, in actual machining processes, when turning a metal workpiece, the high-speed rotation of the cutting tool generates a large amount of metal chips. Under the powerful cutting force, a significant portion of these chips inevitably splashes towards the slots. As the device continues to operate, more and more chips continuously flow into the slots. Since the slots are the key track support for the fixture's sliding, once they are filled with these chips, the fixture's sliding within the slots becomes extremely difficult, significantly reducing adjustment accuracy and severely impacting the clamping efficiency of subsequent workpieces.

[0005] Therefore, it is necessary to design a vertical milling and turning machining center with a power tool holder to solve the above problems. Summary of the Invention

[0026] 4.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 A vertical milling and turning machining center with a power tool holder, comprising a machining unit and a clamping unit.

[0039] The processing unit includes a chassis 11, a processing chamber 12 is provided inside the chassis 11, a processing arm 13 is movably installed on the inner wall of the processing chamber 12, a power tool holder 14 is provided at the output end of the processing arm 13, and a drive seat 15 is provided on the inner bottom surface of the processing chamber 12.

[0040] The clamping unit includes a processing disk 21 fixedly installed on the top surface of the drive base 15. The top surface of the processing disk 21 has three guide grooves 22 arranged in a ring array. A slider 23 is slidably installed on the inner wall of the guide groove 22. The inner and outer walls of the processing disk 21 are fixedly installed with connecting boxes 24 corresponding to the two ends of the guide groove 22. A covering cloth 26 is provided on the inner side of the connecting box 24.

[0041] The clamping unit also includes a take-up reel 25 rotatably mounted on the inner wall of the connecting box 24, a cover roll 26 is disposed on the take-up reel 25, and the pull end of the cover roll 26 passes through the side of the connecting box 24 and is fixedly connected to the side of the slider 23. A coil spring 27 is fitted at the end of the take-up reel 25, and the two ends of the coil spring 27 are fixedly connected to the take-up reel 25 and the connecting box 24 respectively. The inner walls on both sides of the guide groove 22 are provided with receiving grooves 28 corresponding to the cover roll 26, and the width of the cover roll 26 is at least greater than the width of the guide groove 22.

[0042] The metal workpiece to be processed is placed on the processing plate 21 and fixed. After fixing, the processing arm 13 and the drive seat 15 can be opened. When the drive seat 15 is opened, the workpiece can be rotated through the processing plate 21. When the processing arm 13 is opened, the power tool holder 14 can be driven. The power tool holder 14 can accurately intervene and switch tools according to the preset program or real-time processing requirements to complete a variety of complex processes such as milling, drilling, tapping, boring, and end face groove processing, forming a "milling and turning compound, multi-station linkage" processing system.

[0043] The slider 23 is slidably connected to the guide groove 22. Therefore, under the driving action, the slider 23 can slide along the guide groove 22. When the slider 23 slides towards the workpiece, it can clamp the metal workpiece. When the slider 23 slides away from the metal workpiece, it can release the metal workpiece so that the operator can take it out. During the driving process, the slider 23 can roll up and unroll the cover cloth 26 on both sides. Specifically, when the slider 23 slides, it can pull the cover cloth 26. Under the action of the coil spring 27 at the end of the take-up reel 25, the take-up reel 25 has a certain winding force, so it can tighten the cover cloth 26 in the guide groove 22. The two sides of the cover cloth 26 are located in the two receiving grooves 28, which can seal and cover the guide groove 22. The debris during the processing can fall onto the cover cloth 26 and prevent it from entering the guide groove 22 and affecting the sliding of the slider 23.

[0044] Reference Figure 4 , Figure 5 , Figure 7The inner side of the processing disk 21 is provided with a drive assembly corresponding to the three sliders 23. The drive assembly includes drive screws 41 that are rotatably installed on the inner wall of the three guide grooves 22 respectively, and the sliders 23 are screwed to the drive screws 41. A servo motor 42 is fixedly installed on the inner bottom surface of the processing disk 21. The output end of the servo motor 42 is slidably fitted with a drive disk 43. A drive bevel gear ring 44 is fixedly installed on the top surface of the drive disk 43. The ends of the three drive screws 41 all pass through the side of the guide grooves 22 and are fixedly installed with driven bevel gears 45. The driven bevel gears 45 mesh with the drive bevel gear ring 44.

[0045] When fixing a metal workpiece, the operator can first turn on the servo motor 42 and drive the drive disk 43 to rotate through the output end. The drive bevel gear ring 44 on the drive disk 43 meshes with the driven bevel gear 45 at the end of the drive screw 41. Thus, when the drive disk 43 rotates, it can drive the drive screw 41, causing the drive screw 41 to rotate.

[0046] Reference Figure 5 , Figure 9 The top surface of the slider 23 is provided with a clamping structure, which includes a clamping seat 31 on the top surface of the slider 23. Both the clamping seat 31 and the top surface of the slider 23 are symmetrically provided with two threaded holes 32. The inner wall of the threaded hole 32 is screwed with a connecting bolt 33, and a hexagonal end 34 is fixedly installed at the bottom end of the connecting bolt 33.

[0047] Reference Figure 5 , Figure 7 , Figure 8The inner side of the processing tray 21 is provided with three sets of disassembly components corresponding to the three guide grooves 22. The disassembly components include a slide plate 51 slidably installed on the inner wall of the processing tray 21. The slide plate 51 is located directly below the guide groove 22. Two spring telescopic rods 52 are provided through the top surface of the slide plate 51, and the spring telescopic rods 52 are rotatably connected to the through-hole. The telescopic ends of the spring telescopic rods 52 are fixedly installed with screw nuts 53 corresponding to the hexagonal ends 34. A guide platform 54 is fixedly installed on the outer wall of the screw nuts 53. A fixing plate 55 corresponding to the slide plate 51 is fixedly installed on the inner wall of the processing tray 21. Two support springs 56 are symmetrically fixedly installed on the side of the fixing plate 55 opposite to the slide plate 51. The end of the slide plate 51 is rotatably installed with a pivot. The transmission gear 57, the rotating shaft, and the two spring telescopic rods 52 are connected by driven wheels and synchronous belts. Several fixed teeth 58 arranged in a ring array are fixedly installed on the outer wall of the drive disk 43, and the fixed teeth 58 mesh with the transmission gear 57. A fixed ring 59 is fixedly installed on the outer wall of the drive disk 43, and the bottom surface of the fixed ring 59 is in contact with the top surface of the fixed teeth 58. Two electric push rods 510 are symmetrically fixedly installed on the inner top surface of the processing disk 21, and the telescopic end of the electric push rod 510 is movably connected to the top surface of the drive disk 43 through an annular groove. An electromagnet 511 is provided on the top surface of the fixed plate 55. The inner rod and outer rod of the spring telescopic rod 52 are slidably connected by a sliding groove and a guide block, so it can be used for stable rotation.

[0048] When the clamping seat 31 on the top surface of the slider 23 needs to be replaced according to the actual situation of the metal workpiece to be processed, the operator can turn on the servo motor 42 to move the slider 23 to the end of the guide groove 22 away from the metal workpiece. During the sliding process of the slider 23, when the hexagonal end 34 on its bottom surface contacts the guide table 54, since the side of the guide table 54 is inclined, the spring telescopic rod 52 can be shortened as the hexagonal end 34 moves and presses, so that the tightening nut 53 moves downward. When the hexagonal end 34 moves to the top of the tightening nut 53, under the elastic support of the spring telescopic rod 52, the tightening nut 53 can move upward and fit on the outer wall of the hexagonal end 34, realizing the connection between the tightening nut 53 and the hexagonal end 34. Then, the electric push rod 510 is extended. The telescopic end of the electric push rod 510 is slidably connected to the annular groove on the top surface of the drive disk 43. Therefore, when the servo motor 42 drives the drive disk 43 to rotate, the electric push rod 510 will not affect the drive disk 43. When the electric push rod 510 extends, it can drive the drive disk 43 to slide along the output end of the servo motor 42, so that the drive bevel gear ring 44 separates from the driven bevel gear 45. As the drive disk 43 slides, the fixed teeth 58 on its outer wall can mesh with the transmission gear 57, which can stop the electric push rod 510. When the servo motor 42 is activated, it drives the transmission gear 57 to rotate via the drive disk 43 and the fixed teeth 58. The transmission gear 57 is connected to the spring telescopic rod 52 via the driven wheel and the synchronous belt. Therefore, when the transmission gear 57 rotates, it can synchronously drive the two spring telescopic rods 52 and the screw nut 53 to rotate. When the screw nut 53 rotates, it can tighten the hexagonal end 34 and the connecting bolt 33, causing the connecting bolt 33 to slide down along the threaded hole 32 and move out of the threaded hole 32 on the clamp 31, thus releasing the clamp 31 from fixation.

[0049] After the new clamp 31 is replaced, the servo motor 42 can be reversed to drive the screw nut 53 to reverse as well. When the screw nut 53 is reversed, the connecting bolt 33 can be re-tightened into the threaded hole 32 on the clamp 31, thus completing the fixation of the clamp 31. Then, the electric push rod 510 can be opened again to continue extending. When the drive disc 43 moves with the electric push rod 510, it can push the transmission gear 57 through the fixing ring 59, thereby causing the slide plate 51 to slide closer to the fixing plate 55. When the slide plate 51 is close to the fixing plate 55, it can then be... When the electromagnet 511 is turned on, the slide plate 51 can be fixed. At this time, the nut 53 is loosened to separate from the hexagonal end 34. After the electromagnet 511 is turned on to fix the slide plate 51, the electric push rod 510 is shortened so that the drive bevel gear ring 44 re-engages with the driven bevel gear 45 to achieve a reset. Then, the servo motor 42 is turned on to drive the slider 23 to move so that the hexagonal end 34 moves directly above the nut 53. At this time, the electromagnet 511 can be de-energized. Under the action of the support spring 56, the slide plate 51 can be reset for reuse.

[0050] Reference Figure 4 , Figure 9 The clamping structure is equipped with a limiting structure, which includes a clamping plate 61 fixedly installed at one end of the top surface of the slider 23, and two clamping plates 62 corresponding to the clamping seat 31 symmetrically fixedly installed at the other end of the top surface of the slider 23. The clamping plates 62 are made of elastic material. Two slots 63 corresponding to the clamping plates 62 are opened on the side of the clamping seat 31. Two positioning rods 64 are fixedly installed on the bottom surface of the clamping seat 31. Two positioning grooves 65 adapted to the positioning rods 64 are opened on the top surface of the slider 23.

[0051] When the staff removes the clamp 31, they can first pull up the end of the clamp 31 that is close to the clamp plate 61, so that the clamp 31 can be slightly tilted and push against the clamp plate 62, so that the clamp plate 62 moves out of the slot 63, and the clamp 31 can be taken out upward. At this time, the positioning rod 64 can be separated from the positioning groove 65, and the clamp 31 can be removed. After replacing the clamp 31, the clamp 31 can be first inserted into the slot 63 on the side of the clamp 31 and then the clamp 31 can be pressed down to complete the installation of the clamp 31. The clamp 31 is initially fixed by the cooperation of the clamp plate 62 and the slot 63.

[0052] The specific working principle of this invention is as follows:

[0053] In use, the metal workpiece to be processed can be placed on the processing plate 21 and fixed by the clamping structure. After the fixation is completed, the processing arm 13 and the drive seat 15 can be opened. When the drive seat 15 is opened, the workpiece can be rotated by the processing plate 21. When the processing arm 13 is opened, the power tool holder 14 can be driven. The power tool holder 14 can accurately intervene and switch tools according to the preset program or real-time processing requirements to complete a variety of complex processes such as milling, drilling, tapping, boring, and end face groove processing, forming a "milling and turning compound, multi-station linkage" processing system.

[0054] When fixing the metal workpiece, the operator can first turn on the servo motor 42 to drive the drive disk 43 to rotate through the output end. The drive bevel gear ring 44 on the drive disk 43 meshes with the driven bevel gear 45 at the end of the drive screw 41. Thus, when the drive disk 43 rotates, it drives the drive screw 41, causing the drive screw 41 to rotate. The slider 23 is slidably connected to the guide groove 22 and screwed to the drive screw 41. Therefore, when the drive screw 41 rotates, it can drive the slider 23 to slide along the guide groove 22. Furthermore, by changing the rotation direction of the drive screw 41, the sliding direction of the slider 23 can be changed. When the slider 23 slides towards the workpiece, it can clamp the metal workpiece. When the slider 23 slides away from the metal workpiece, it can release the metal workpiece so that the operator can remove it. During the process of the slider 23 being driven by the drive screw 41, the slider 23 can roll up and unroll the cover cloth 26 on both sides. Specifically, when the slider 23 slides, it can pull the cover cloth 26. Under the action of the coil spring 27 at the end of the take-up reel 25, the take-up reel 25 has a certain winding force, so it can tighten the cover cloth 26 in the guide groove 22. The two sides of the cover cloth 26 are located in the two receiving grooves 28, which can achieve a sealed cover of the guide groove 22. The debris during the processing can fall onto the cover cloth 26, preventing it from entering the guide groove 22 and affecting the sliding of the slider 23.

[0055] If the clamping seat 31 on the top surface of the slider 23 needs to be replaced according to the actual situation of the metal workpiece to be processed, the operator can turn on the servo motor 42 to move the slider 23 to the end of the guide groove 22 away from the metal workpiece. During the sliding process of the slider 23, when the hexagonal end 34 on its bottom surface contacts the guide table 54, since the side of the guide table 54 is inclined, the spring telescopic rod 52 can be shortened as the hexagonal end 34 moves and presses, so that the tightening nut 53 moves downward. When the hexagonal end 34 moves to the top of the tightening nut 53, under the elastic support of the spring telescopic rod 52, the tightening nut 53 can move upward and fit on the outer wall of the hexagonal end 34, realizing the connection between the tightening nut 53 and the hexagonal end 34. Then, the electric push rod 510 is extended. The telescopic end of the electric push rod 510 is slidably connected to the annular groove on the top surface of the drive disk 43. Therefore, when the servo motor 42 drives the drive disk 43 to rotate, the electric push rod 510 will not affect the drive disk 43. When the electric push rod 510 extends, it can drive the drive disk 43 to slide along the output end of the servo motor 42, so that the drive bevel gear ring 44 separates from the driven bevel gear 45. As the drive disk 43 slides, the fixed teeth 58 on its outer wall can mesh with the transmission gear 57, which can stop the electric push rod 510. When the servo motor 42 is activated, it drives the transmission gear 57 to rotate via the drive disk 43 and the fixed teeth 58. The transmission gear 57 is connected to the spring telescopic rod 52 via the driven wheel and the synchronous belt. Therefore, when the transmission gear 57 rotates, it can synchronously drive the two spring telescopic rods 52 and the screw nut 53 to rotate. When the screw nut 53 rotates, it can tighten the hexagonal end 34 and the connecting bolt 33, causing the connecting bolt 33 to slide down along the threaded hole 32 and move out of the threaded hole 32 on the clamp 31, thus releasing the clamp 31 from fixation.

[0056] The operator can then remove the clamp 31. To remove it, first pull up the end of the clamp 31 closest to the clamping plate 61, allowing the clamp 31 to tilt slightly and push against the clamping plate 62, causing the clamping plate 62 to move out of the slot 63. The clamp 31 can then be lifted upwards. At this point, the positioning rod 64 can separate from the positioning groove 65, completing the removal of the clamp 31. After replacing the clamp 31, first snap the slot 63 on the side of the clamp 31 onto the clamping plate 62, then press the clamp 31 downwards to complete the installation. The clamp 31 is initially fixed by the cooperation of the clamping plate 62 and the slot 63. Subsequently, the servo motor 42 can be reversed to drive the screw nut 53 to reverse as well. When the screw nut 53 reverses, the connecting bolt 33 can be re-tightened into the threaded hole 32 on the clamp 31, thus completing the fixation of the clamp 31.

[0057] After replacing the clamp 31, the electric push rod 510 can be opened again to extend further. When the drive plate 43 moves with the electric push rod 510, it can push the transmission gear 57 through the fixing ring 59, thereby causing the slide plate 51 to slide closer to the fixing plate 55. When the slide plate 51 is close to the fixing plate 55, the electromagnet 511 can be opened to fix the slide plate 51. At this time, the nut 53 is loosened to separate from the hexagonal end 34. After the electromagnet 511 is opened to fix the slide plate 51, the electric push rod 510 is shortened so that the drive bevel gear ring 44 re-engages with the driven bevel gear 45 to achieve reset. Then, the servo motor 42 is turned on to drive the slider 23 to move, so that the hexagonal end 34 moves out of the position directly above the nut 53. At this time, the electromagnet 511 can be de-energized. Under the action of the support spring 56, the slide plate 51 can be reset for reuse.
