Description

Technical Field

[0001] The present invention relates to the technical field of machining centers, and particularly to a vertical milling and turning compound machining center with a powered tool holder. Background Art

[0002] A vertical milling and turning compound machining center is an advanced numerically controlled machine tool that integrates milling and turning functions, featuring high precision, high efficiency, and multiple functions. It is widely used in the machining fields of high-precision and complex-shaped parts such as aerospace, automotive manufacturing, and mold processing. It can install a variety of special tools, reduce tool change time, has a compact and beautiful appearance, and improves the way of space utilization.

[0003] After retrieval, a Chinese patent with the publication number CN113814733A discloses a vertical turning and milling compound machining center, which 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 and milling spindle unit, and a vertical tool magazine. The vertical spindle box can be lifted up and down through the first lifting mechanism on the first saddle to machine the workpiece to be machined on the rotary table. The turning and milling spindle unit can be lifted up and down through the second lifting mechanism on the second saddle to perform turning, milling, and cutting operations on the workpiece to be machined on the rotary table. The rotary table includes a workbench, a turntable, a fixed seat, a driving mechanism, a hydraulic cylinder, a brake ring, and a brake disc. It solves the problems of the single machining performance of existing machine tools and the inaccurate braking of the rotary table affecting the machining accuracy of workpieces. However, when this solution is actually used, there are still the following deficiencies:

[0004] Generally, in order to firmly clamp metal machining workpieces of various different sizes and shapes, a specially designed fixture is installed in a specific card slot of the machine tool. Relying on the track structure provided by the card slot, the fixture can slide left and right in the card slot flexibly to conveniently adjust the position. However, in the actual machining process, when starting the turning operation on the metal workpiece, the tool rotates at a high speed to cut the metal, generating a large amount of metal chips. Under the action of the strong cutting force, a considerable part of these chips will inevitably splash towards the direction of the card slot. As the device is used, more and more chips continuously pour into the inside of the card slot. And the card slot, as the key track support for the sliding of the fixture, once occupied by these chips, makes the sliding of the fixture in the card slot extremely stuck, and the adjustment accuracy is greatly reduced, seriously affecting the subsequent clamping efficiency of the workpiece.

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

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0038] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , the vertical milling and turning compound machining center with a powered tool holder includes a machining unit and a clamping unit.

[0039] Among them, the machining unit includes a chassis 11, a machining chamber 12 is arranged inside the chassis 11, a machining arm 13 is movably installed on the inner wall of the machining chamber 12, a powered tool holder 14 is arranged at the output end of the machining arm 13, and a drive seat 15 is arranged on the inner bottom surface of the machining chamber 12.

[0040] Among them, the clamping unit includes a processing disk 21 fixedly installed on the top surface of the driving seat 15. Three guiding grooves 22 distributed in an annular array are formed on the top surface of the processing disk 21. A sliding block 23 is slidably installed on the inner wall of the guiding groove 22. Connecting boxes 24 corresponding to both ends of the guiding groove 22 are fixedly installed on both the inner wall and the outer wall of the processing disk 21. A covering cloth 26 is arranged inside the connecting box 24.

[0041] The clamping unit further includes a winding disk 25 rotatably installed on the inner wall of the connecting box 24. The covering cloth 26 is arranged on the winding disk 25. The pulling end of the covering cloth 26 passes through the side surface of the connecting box 24 and is fixedly connected to the side surface of the sliding block 23. A winding spring 27 is sleeved on the end of the winding disk 25, and both ends of the winding spring 27 are fixedly connected to the winding disk 25 and the connecting box 24 respectively. Accommodating grooves 28 corresponding to the covering cloth 26 are formed on both inner walls of the guiding groove 22, and the width of the covering cloth 26 is at least greater than the width of the guiding groove 22.

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

[0043] The sliding block 23 is slidably connected to the guiding groove 22. Therefore, under the driving action, the sliding block 23 can be driven to slide along the guiding groove 22. When the sliding block 23 slides towards the direction close to the workpiece, the clamping of the metal workpiece can be realized. When the sliding block 23 slides towards the direction away from the metal workpiece, the loosening of the metal workpiece can be realized for the staff to take out. During the driving process of the sliding block 23, the sliding of the sliding block 23 can wind and unwind the covering cloth 26 on both sides. Specifically, when the sliding block 23 slides, it can pull the covering cloth 26. Under the action of the winding spring 27 at the end of the winding disk 25, the winding disk 25 has a certain winding force. Therefore, the covering cloth 26 can be tightened in the guiding groove 22, and both sides of the covering cloth 26 are located in the two accommodating grooves 28 to realize the sealed covering of the guiding groove 22. The debris during the processing can fall onto the covering cloth 26 to avoid entering the guiding groove 22 and affecting the sliding of the sliding block 23.

[0044] Refer to Figure 4 、 Figure 5 、 Figure 7, a driving component corresponding to the three sliders 23 is arranged inside the processing disk 21. The driving component includes driving screws 41 respectively rotatably installed on the inner walls of the three guiding grooves 22, and the slider 23 is screwed with the driving screw 41. A servo motor 42 is fixedly installed on the inner bottom surface of the processing disk 21. A driving disk 43 is slidably sleeved on the output end of the servo motor 42. A driving bevel gear ring 44 is fixedly installed on the top surface of the driving disk 43. The ends of the three driving screws 41 all pass through the sides of the guiding grooves 22 and are fixedly installed with driven bevel gears 45, and the driven bevel gears 45 are meshed with the driving bevel gear ring 44.

[0045] When fixing the metal workpiece, the staff can first turn on the servo motor 42 to drive the driving disk 43 to rotate through the output end. The driving bevel gear ring 44 on the driving disk 43 is meshed with the driven bevel gear 45 at the end of the driving screw 41. Then, when the driving disk 43 rotates, it can drive the driving screw 41, so that the driving screw 41 rotates.

[0046] Refer to Figure 5 , Figure 9 , a clamping structure is arranged on the top surface of the slider 23. The clamping structure includes a clamping seat 31 arranged on the top surface of the slider 23. Two threaded holes 32 are symmetrically opened on the top surfaces of the clamping seat 31 and the slider 23. A connecting bolt 33 is screwed on the inner wall of the threaded hole 32, and a hexagonal end 34 is fixedly installed at the bottom end of the connecting bolt 33.

[0047] Refer to Figure 5 , Figure 7 , Figure 8, three disassembly components corresponding to the three guide grooves 22 are arranged inside the processing disk 21. The disassembly component includes a sliding plate 51 slidably mounted on the inner wall of the processing disk 21. The sliding plate 51 is located directly below the guide groove 22. Two spring telescopic rods 52 are arranged through the top surface of the sliding plate 51, and the spring telescopic rods 52 are rotatably connected to the through position. A screwing nut 53 corresponding to the hexagonal end 34 is fixedly installed at the telescopic end of the spring telescopic rod 52. A guide platform 54 is fixedly installed on the outer wall of the screwing nut 53. A fixing plate 55 corresponding to the sliding plate 51 is fixedly installed on the inner wall of the processing disk 21. Two support springs 56 are symmetrically and fixedly installed on the side surface of the fixing plate 55 opposite to the sliding plate 51. The end of the sliding plate 51 is rotatably installed with a transmission gear 57 through a rotating shaft. The rotating shaft is connected to the two spring telescopic rods 52 through a driven wheel and a synchronous belt. A plurality of fixed teeth 58 distributed in an annular array are fixedly installed on the outer wall of the driving disk 43, and the fixed teeth 58 are engaged with the transmission gear 57. A fixing ring 59 is fixedly installed on the outer wall of the driving disk 43, and the bottom surface of the fixing ring 59 is attached to the top surface of the fixed teeth 58. Two electric push rods 510 are symmetrically and 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 driving disk 43 through an annular groove. An electromagnet 511 is arranged on the top surface of the fixing plate 55. The inner rod and the outer rod of the spring telescopic rod 52 are slidably connected through a chute and a guide block, so it can be used for stable rotation.

[0048] When it is necessary to replace the clamp seat 31 on the top surface of the slider 23 according to the actual situation of the metal workpiece to be processed, the staff 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 platform 54, since the side of the guide platform 54 is an inclined surface, the spring telescopic rod 52 can be shortened as the hexagonal end 34 is pressed when it moves, so that the screw nut 53 moves downward. When the hexagonal end 34 moves to the top of the screw nut 53, the screw nut 53 can move upward to be mounted on the outer wall of the hexagonal end 34 under the elastic support of the spring telescopic rod 52, thereby realizing the connection between the screw nut 53 and the hexagonal end 34. The electric push rod 510 is then opened and extended. The telescopic end of the electric push rod 510 is slidably connected with the annular groove on the top surface of the driving disk 43. Therefore, when the servo motor 42 drives the driving disk 43 to rotate, the electric push rod 510 will not affect the driving disk 43. When the electric push rod 510 is extended, it can drive the driving disk 43 to slide along the output end of the servo motor 42, so that the driving bevel gear ring 44 is separated from the driven bevel gear 45. As the driving disk 43 slides, the fixed teeth 58 on the outer wall of the driving disk 43 can mesh with the transmission gear 57, so that the electric push rod 510 can stop. 10 is extended, and the servo motor 42 is turned on to drive the transmission gear 57 to rotate through the driving disk 43 and the fixed teeth 58. The transmission gear 57 is connected to the spring telescopic rod 52 through 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 nut 53 to rotate. When the nut 53 rotates, the hexagonal end 34 and the connecting bolt 33 can be screwed, so that the connecting bolt 33 slides downward along the threaded hole 32 and moves out of the threaded hole 32 on the clamp seat 31, thereby releasing the fixation of the clamp seat 31.

[0049] After the replacement of the new clamping seat 31 is completed, the servo motor 42 can be reversed to drive the nut 53 to reverse. When the nut 53 is reversed, the connecting bolt 33 can be screwed back into the threaded hole 32 on the clamping seat 31, thus completing the fixation of the clamping seat 31. Subsequently, the electric push rod 510 can be turned on again to continue extending. When the driving disc 43 moves with the electric push rod 510, it can push the transmission gear 57 through the fixing ring 59, so that the slide plate 51 slides towards the direction close to the fixed plate 55. When the slide plate 51 approaches the fixed plate 55, the electromagnet 511 can be turned on at this time to fix the slide plate 51. At this time, the nut 53 is separated 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 driving bevel gear ring 44 meshes with the driven bevel gear 45 again 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 directly above the nut 53. At this time, the electromagnet 511 can be powered off, and under the action of the support spring 56, the slide plate 51 can be reset for reuse.

[0050] Refer to Figure 4 、 Figure 9 As shown in

[0051] When the staff installs the clamping seat 31, the end of the clamping seat 31 close to the clamping plate 61 can be pulled up first, so that the clamping seat 31 can be slightly tilted and push the clamping plate 62, so that the clamping plate 62 moves out of the clamping groove 63, and then the clamping seat 31 can be taken out upward. At this time, the positioning rod 64 can be separated from the positioning groove 65 to complete the removal of the clamping seat 31. After replacing the new clamping seat 31, the clamping groove 63 on the side of the clamping seat 31 can be clamped on the clamping plate 62 first, and then the clamping seat 31 can be pressed downward to complete the installation of the clamping seat 31, and the clamping seat 31 can be preliminarily fixed through the cooperation of the clamping plate 62 and the clamping groove 63.

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

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

[0054] When fixing the metal workpiece, the staff can first activate the servo motor 42 to drive the driving disk 43 to rotate through the output end. The driving bevel gear ring 44 on the driving disk 43 meshes with the driven bevel gear 45 at the end of the driving screw 41. Then, when the driving disk 43 rotates, it can drive the driving screw 41, causing the driving screw 41 to rotate. The slider 23 is slidably connected to the guiding groove 22 and is screwed to the driving screw 41. Therefore, when the driving screw 41 rotates, it can drive the slider 23 to slide along the guiding groove 22, and by changing the rotation direction of the driving 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, and when the slider 23 slides away from the metal workpiece, it can loosen the metal workpiece for the staff to take out. During the process of the slider 23 being driven by the driving screw 41, the slider 23 can wind and unwind the covering cloth 26 on both sides. Specifically, when the slider 23 slides, it can pull the covering cloth 26. Under the action of the torsion spring 27 at the end of the winding disk 25, the winding disk 25 has a certain winding force, so it can tighten the covering cloth 26 in the guiding groove 22. The two sides of the covering cloth 26 are located in the two receiving grooves 28, realizing the sealed covering of the guiding groove 22. The debris during the processing can fall onto the covering cloth 26, preventing it from entering the guiding groove 22 and affecting the sliding of the slider 23.

[0055] If it is necessary to replace the clamp seat 31 on the top surface of the slider 23 according to the actual situation of the metal workpiece to be processed, the staff 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 platform 54, since the side of the guide platform 54 is an inclined surface, the spring telescopic rod 52 can be shortened as the hexagonal end 34 is pressed when it moves, so that the screw nut 53 moves downward. When the hexagonal end 34 moves to the top of the screw nut 53, the screw nut 53 can move upward to be mounted on the outer wall of the hexagonal end 34 under the elastic support of the spring telescopic rod 52, thereby realizing the connection between the screw nut 53 and the hexagonal end 34. The electric push rod 510 is then opened and extended. The telescopic end of the electric push rod 510 is slidably connected with the annular groove on the top surface of the driving disk 43. Therefore, when the servo motor 42 drives the driving disk 43 to rotate, the electric push rod 510 will not affect the driving disk 43. When the electric push rod 510 is extended, it can drive the driving disk 43 to slide along the output end of the servo motor 42, so that the driving bevel gear ring 44 is separated from the driven bevel gear 45. As the driving disk 43 slides, the fixed teeth 58 on the outer wall of the driving disk 43 can mesh with the transmission gear 57, so that the electric push rod 510 can stop. 10 is extended, and the servo motor 42 is turned on to drive the transmission gear 57 to rotate through the driving disk 43 and the fixed teeth 58. The transmission gear 57 is connected to the spring telescopic rod 52 through 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 nut 53 to rotate. When the nut 53 rotates, the hexagonal end 34 and the connecting bolt 33 can be screwed, so that the connecting bolt 33 slides downward along the threaded hole 32 and moves out of the threaded hole 32 on the clamp seat 31, thereby releasing the fixation of the clamp seat 31.

[0056] The staff can remove the clamp seat 31. When removing, the end of the clamp seat 31 close to the clamp plate 61 can be pulled up first, so that the clamp seat 31 can be slightly tilted and the clamp plate 62 can be pushed up, so that the clamp plate 62 moves out of the slot 63, and the clamp seat 31 can be taken out upward. At this time, the positioning rod 64 can be separated from the positioning slot 65, and the clamp seat 31 is taken out. After replacing the new clamp seat 31, the slot 63 on the side of the clamp seat 31 can be clamped onto the clamp plate 62, and then the clamp seat 31 can be pressed downward to complete the installation of the clamp seat 31, and the clamp seat 31 can be initially fixed through the cooperation of the clamp plate 62 and the slot 63. Then, the servo motor 42 can be reversed to drive the screw nut 53 to reverse. When the screw nut 53 is reversed, the connecting bolt 33 can be screwed back into the threaded hole 32 on the clamp seat 31 to complete the fixing of the clamp seat 31.

[0057] After the clamping seat 31 is replaced, the electric push rod 510 can be turned on again to continue extending. When the driving disc 43 moves with the electric push rod 510, it can push the transmission gear 57 through the fixing ring 59, so that the slide plate 51 slides towards the fixing plate 55. When the slide plate 51 approaches the fixing plate 55, the electromagnet 511 can be turned on to fix the slide plate 51. At this time, turn the nut 53 to separate it from the hexagonal end 34. After turning on the electromagnet 511 to fix the slide plate 51, shorten the electric push rod 510 to make the driving bevel gear ring 44 mesh with the driven bevel gear 45 again to achieve reset. Then turn on the servo motor 42 to drive the slider 23 to move, so that the hexagonal end 34 moves out directly above the nut 53. At this time, the electromagnet 511 can be powered off, and the slide plate 51 can be reset under the action of the support spring 56 for reuse.
