Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically an integrated and optimized power turret structure. Background Technology

[0002] A rotary turret is a general term for automatic tool changers and tool drive devices in CNC machine tools. Powered turrets are commonly used in mill-turn machining centers and are one of the core components of such centers. Multiple tools can be mounted on the turret along the circumference of the tool head. The tools are controlled by a program to perform tool changing, tool feed, tool retraction, and rotary cutting operations.

[0003] For example, Chinese Patent No. 2021223986608 discloses a novel servo-powered turret structure for automatic tool changing. It is difficult to achieve the same axis between its piston tooth disk and tool magazine. Even if the two are aligned, the position between the piston tooth disk and tool magazine will still deviate after long-term operation. Therefore, when the piston tooth disk moves towards the tool magazine, it will not only collide with the saw teeth on the inner wall of the tool magazine, affecting its service life, but it is also difficult to completely lock the saw teeth on the inner wall of the tool magazine. That is, there will be a gap between the outer ring of the piston tooth disk and the saw teeth on the inner wall of the tool magazine when locking, which will cause the tool magazine angle to be unable to be locked. This not only makes tool changing difficult, but also affects the subsequent working stability of the tool.

[0004] For example, Chinese Patent No. 2020222725042 discloses a new type of turret, in which the main motor transmits power to the drive shaft via a belt. The belt transmission has poor stability, and kinetic energy is easily lost. Moreover, it is prone to breakage after long working time. Furthermore, when the cutter head rotates, the mounting protrusion and the arc-shaped guide groove are needed for guidance and cooperation. Apart from this, there are no other positions for limiting and guiding, which affects the ease of tool assembly.

[0005] For example, Chinese Patent No. 2022212382492 discloses a Y-axis power turret, whose slide rails are set on the left and right sides of the sliding seat. At the same time, the machine housing also has two sliding grooves on the corresponding positions on the inner wall. Therefore, it occupies a large space on the left and right sides of the cutter head, resulting in a large overall size of the turret. This requires the machine tool to reserve more space to meet the turret's operation, which is a waste of space. In addition, the large size of the turret results in poor flexibility during operation, and it can only meet the rotational cutting of the workpiece on one side of the machine tool, resulting in low working efficiency.

[0006] Because existing rotary turret technologies have many shortcomings, further improvements are necessary. Summary of the Invention

[0007] The present invention aims to provide an integrated and optimized power turret structure to overcome the shortcomings of the prior art.

[0008] An integrated and optimized power turret structure designed for this purpose includes a base, a turret, a tool holder assembly, and a main housing. The main housing is single-arm suspended and reciprocatingly guided and slidable on the base. The main housing is equipped with a turret servo motor, a tool holder servo motor, a floating crank, and a rotary gear. The turret servo motor is connected to the turret drive via the rotary gear. The floating crank adaptively floats on the main housing and engages with the rotary gear without clearance when moving in the direction of the rotary gear. The tool holder servo motor is driven and connected to the tool holder assembly when the floating crank and the rotary gear are engaged.

[0009] The main housing is provided with at least two sliding areas, and the at least two sliding areas are located on the same single side of the central axis of the main housing; the base is provided with at least two sliding engagement areas; the at least two sliding engagement areas are located on the same single side of the central axis of the base and correspond to the at least two sliding areas respectively; the at least two sliding areas and the at least two sliding engagement areas are in a concave-convex guide sliding engagement to realize the single-arm suspended reciprocating guide sliding of the main housing on the base.

[0010] A longitudinal slider and a longitudinal slide rail are provided between at least two of the sliding areas and at least two of the sliding engagement areas; the longitudinal slider and the longitudinal slide rail are in a longitudinal guiding sliding engagement.

[0011] The base is equipped with a housing servo motor, a belt drive assembly, and a lead screw; the housing servo motor is fixedly mounted on the base; the belt drive assembly is connected to the housing servo motor and the lead screw respectively; the lead screw is rotatably mounted on the base and drives the main housing during rotation.

[0012] The turret has a ring array of several cutting tools; the tool holder servo motor is equipped with an encoder, and its power output end is driven and connected to the tool holder assembly; the tool holder assembly includes a positioning plate and a tool holder drive shaft; the positioning plate is provided with a notch; the outer end of the tool holder drive shaft is located on the notch, and a tool groove is provided thereon.

[0013] The tool holder servo motor controls the rotation angle of the tool holder drive shaft through the encoder, so that the mounting slot of the tool groove is always parallel to the side of the positioning plate when the tool holder drive shaft stops rotating.

[0014] When the turret rotates, the tool assembly part engages with the side guide of the positioning plate and is guided onto the assembly slot of the tool groove.

[0015] The tool holder assembly also includes a tool holder housing, in which a bevel gear transmission pair is provided; the inner end of the tool holder drive shaft is located inside the tool holder housing and meshes with the bevel gear transmission pair; the positioning plate is located on the side of the tool holder drive shaft and is fixedly mounted on the tool holder housing.

[0016] The main housing has a rotating cavity; the tool holder box is located at the opening on one side of the rotating cavity; a tool holder servo motor mounting bracket is fixedly installed at the opening on the other side of the rotating cavity; the tool holder servo motor is fixedly installed on the tool holder servo motor mounting bracket, and its power output end is driven and connected to a transmission rod, which passes through the rotating cavity and engages with the bevel gear transmission pair.

[0017] The tool holder servo motor mounting bracket is also provided with an extension column, which extends toward the tool holder box and passes through the rotating cavity. An assembly bracket is provided on the extension column; the tool holder box is fixedly mounted on the assembly bracket; and the transmission rod is located inside the extension column.

[0018] The extension column is fitted with a turret spindle, which is fixedly connected to the turret and fitted with a main bearing. The turret spindle rotates within the rotating cavity via the main bearing.

[0019] The rotating gear is rotatably sleeved on the extension column; the turret servo motor is driven and connected to the rotating gear; the rotating gear is fixedly connected to the turret spindle; the floating gear is adaptively floating and sleeved on the extension column, and engages and locks with the rotating gear or disengages from the rotating gear when floating.

[0020] The present invention, through the improvement of the above-described structure, has the following advantages compared with the prior art:

[0021] 1. By utilizing the adaptive floating of the floating chuck, it can move adaptively in different directions. When moving towards the rotating gear, it can achieve backlash-free meshing with the rotating gear, ultimately enabling the turret to achieve true angle locking. This avoids the problems of existing floating chucks that can only move axially, resulting in the inability to lock the turret angle, leading to difficulties in tool changing and poor tool working stability. This ensures smooth tool changing and improves tool working stability.

[0022] 2. When the floating gear and rotary gear are engaged, the tool holder servo motor can be used to drive the tool holder assembly. This not only has a simple structure, high transmission efficiency, and stability, but also allows for precise control of the rotation angle of the tool holder assembly. This ensures that the angle of the tool holder drive shaft on the tool holder assembly is always positioned at a specified location when it stops rotating. This ensures that when the turret rotates, the mounting slot of the tool slot is parallel to the side of the positioning plate, and the tool mounting part can also be guided and fitted with the side of the positioning plate and guided onto the mounting slot of the tool slot. This effectively avoids interference between the tool and the tool holder drive shaft during assembly and also ensures smooth assembly between the tool and the tool holder drive shaft.

[0023] 3. Since the main housing is guided and slid on the base by a single-arm suspension, it will not occupy the other single-side space of the power turret, thereby reducing the overall volume of the power turret and improving the space utilization of the CNC machine tool. Moreover, since the other single-side space of the power turret can be freed up, the tools on the tool holder assembly have sufficient machining positions and can realize bidirectional machining on the CNC machine tool, improving work efficiency and flexibility.

[0039] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] See Figures 1-15 This integrated and optimized power turret structure includes a base 40, a turret 2, a tool holder assembly, and a main housing 1. The main housing 1 is suspended in a single-arm reciprocating guide sliding manner on the base 40. The main housing 1 is equipped with a turret servo motor 3, a tool holder servo motor 25, a floating gear 4, and a rotating gear 5. The turret servo motor 3 is driven and connected to the turret 2 through the rotating gear 5. The floating gear 4 adaptively floats on the main housing 1 and engages with the rotating gear 5 without clearance when moving in the direction of the rotating gear 5. The tool holder servo motor 25 is driven and connected to the tool holder assembly when the floating gear 4 and the rotating gear 5 are engaged.

[0042] In this embodiment, the main housing 1 is provided with at least two sliding areas, which are located on the same side of the central axis X of the main housing 1; the base 40 is provided with at least two sliding engagement areas; the at least two sliding engagement areas are located on the same side of the central axis Y of the base 40 and correspond to the at least two sliding areas respectively; the at least two sliding areas and the at least two sliding engagement areas are in a concave-convex guide sliding engagement to realize the single-arm suspended reciprocating guide sliding of the main housing 1 on the base 40.

[0043] At least two sliding areas are provided on the same side of the central axis X of the main housing 1. Correspondingly, at least two sliding engagement areas are provided on the same side of the central axis Y of the base 40. By utilizing the concave-convex guide sliding engagement between the at least two sliding areas and the sliding engagement areas, the main housing 1 can be suspended and reciprocated on the base 40 in a single-arm suspended manner. Since at least two sliding areas and at least two sliding engagement areas are respectively set on the same side, they will not occupy the space on the other side of the power turret, thereby reducing the overall volume of the power turret and improving the space utilization of the CNC machine tool. Moreover, since the space on the other side of the power turret can be freed up, the tool 26 on the tool holder assembly has sufficient machining position and can realize bidirectional machining on the CNC machine tool, improving work efficiency and flexibility.

[0044] A longitudinal slider 45 and a longitudinal slide rail 46 are provided between at least two sliding areas and at least two sliding engagement areas; the longitudinal slider 45 and the longitudinal slide rail 46 are in a longitudinal guiding sliding engagement.

[0045] Specifically, at least two sliding areas are respectively located on different sides of the main housing 1; at least two sliding mating areas are respectively located on different sides of the base 40.

[0046] That is, if the main body 1 and the base 40 are both polygonal in shape, at least two sliding areas and at least two sliding mating areas can be set on the same single side, while the other symmetrical single side is left empty and no components are set there.

[0047] In this preferred embodiment, at least two sliding areas are respectively arranged on two adjacent sides of the main housing 1; at least two sliding mating areas are respectively arranged on two adjacent sides of the base 40, which helps to improve space utilization.

[0048] In this embodiment, the main housing 1 is provided with a first sliding side 41 and a second sliding side 42 on its adjacent sides; the first sliding side 41 and the second sliding side 42 are arranged adjacently and form two sliding areas; the base 40 is provided with a first sliding mating side 43 and a second sliding mating side 44 on its adjacent sides; the first sliding mating side 43 and the second sliding mating side 44 are arranged adjacently and form two sliding mating areas.

[0049] The first sliding side 41 and the second sliding side 42, and the first sliding mating side 43 and the second sliding mating side 44, are respectively L-shaped fits. That is, the first sliding side 41 and the second sliding side 42 are perpendicular to each other, and the first sliding mating side 43 and the second sliding mating side 44 are perpendicular to each other, thereby improving the stress stability between the main housing 1 and the base 40 when suspended by a single arm, so that the main housing 1 will not tilt or sway when sliding.

[0050] Longitudinal sliders 45 are fixedly provided on the first sliding side 41 and the second sliding side 42 respectively; longitudinal slide rails 46 are fixedly provided on the first sliding side 43 and the second sliding side 44 respectively; the longitudinal sliders 45 and the longitudinal slide rails 46 are longitudinally guided and slidably engaged.

[0051] The main housing 1 is guided to slide longitudinally on the base 40 via longitudinal sliders 45 in two areas on the same side of the base 40. This effectively and accurately guides the main housing 1 to complete longitudinal adjustment on the base 40, thereby improving the machining accuracy of the workpiece.

[0052] The base 40 is provided with a limiting part that limits the sliding of the main box 1.

[0053] In this embodiment, the limiting part includes an upper limiting part 52 and a lower limiting part 53. When the main housing 1 slides to the upper stop, it acts as a limiting force on the upper limiting part 52, and when the main housing 1 slides to the lower stop, it acts as a limiting force on the lower limiting part 53, thereby limiting the longitudinal sliding distance of the main housing 1.

[0054] The base 40 is equipped with a housing servo motor 47, a belt drive assembly, and a lead screw 48. The housing servo motor 47 is fixedly mounted on the base 40. The belt drive assembly is connected to the housing servo motor 47 and the lead screw 48 respectively. The lead screw 48 is rotatably mounted on the base 40 and drives the main housing 1 when rotating.

[0055] In this embodiment, the belt drive assembly includes a drive pulley 54, a driven pulley 55, and a drive belt; the housing servo motor 47 is fixedly mounted on the base 40, and its power output end is driven and connected to the drive pulley 54; the main housing 1 is provided with a threaded hole 49; the base 40 is provided with a rotating hole 56; the driven pulley 55 is fixedly connected to the lead screw 48; the drive belt surrounds the drive pulley 54 and the driven pulley 55; the lead screw 48 rotates on the rotating hole 56 through the cooperation of the housing servo motor 47, the drive pulley 54, the driven pulley 55, and the drive belt, and meshes with the threaded hole 49 during rotation to drive the main housing 1 to slide back and forth relative to the base 40.

[0056] A disc 50 is also fixedly installed on the lead screw 48 or belt drive assembly; a hydraulic brake 51 is also installed on the base 40, and the hydraulic brake 51 is loosely and tightly engaged with the disc 50.

[0057] In this embodiment, a disc 50 is fixedly mounted on the lead screw 48. When the hydraulic brake 51 is filled with oil and pressurized, it clamps the disc 50, fixing the lead screw 48 and preventing it from rotating, thus fixing the position between the main housing 1 and the base 40. When the hydraulic brake 51 is released and pressed obliquely, it releases the disc 50, allowing the lead screw 48 to rotate and drive the main housing 1 to slide back and forth relative to the base 40.

[0058] The turret 2 has a ring array of several cutting tools 26; the tool holder servo motor 25 is equipped with an encoder, and its power output end is connected to the tool holder assembly for driving; the tool holder assembly includes a positioning plate 27 and a tool holder drive shaft 28; the positioning plate 27 is provided with a notch 29; the outer end of the tool holder drive shaft 28 is located on the notch 29, and a tool groove 30 is provided on it.

[0059] The tool holder servo motor 25 controls the rotation angle of the tool holder drive shaft 28 through an encoder so that the mounting slot of the tool groove 30 is always parallel to the side of the positioning plate 27 when the tool holder drive shaft 28 stops rotating.

[0060] When the turret 2 rotates, the mounting part 33 of the tool 26 engages with the side guide of the positioning plate 27 and is guided onto the mounting slot of the tool groove 30.

[0061] Using a tool holder servo motor 25 to drive the tool holder assembly not only results in a simple structure, high transmission efficiency, and stability, but also allows for precise control of the rotation angle of the tool holder assembly. This ensures that the angle of the tool holder drive shaft 28 remains at a specified position when it stops rotating. Consequently, when the turret 2 rotates, the mounting slot of the tool groove 30 is parallel to the side of the positioning plate 27, and the mounting part 33 of the tool 26 can also guide and cooperate with the side of the positioning plate 27 and be guided and mounted on the mounting slot of the tool groove 30. This effectively avoids interference between the tool 26 and the tool holder drive shaft 28 during assembly and ensures smooth assembly between the tool 26 and the tool holder drive shaft 28.

[0062] The positioning plate 27 can protect the tool holder assembly and prevent the waste generated by the tool 26 during operation from damaging the tool holder assembly, while also providing guidance for the rotation of the tool 26.

[0063] Furthermore, the tool holder servo motor 25 is equipped with an encoder, which controls the rotation angle of the tool holder drive shaft 28. During operation, the encoder precisely controls the rotation angle of the tool holder drive shaft 28, ensuring that the mounting slot of the tool groove 30 remains parallel to the side of the positioning plate 27 when the tool holder drive shaft 28 stops rotating, and ensuring that the mounting slot of the tool holder drive shaft 28 is compatible with the mounting portion 33 of the tool 26 during assembly.

[0064] The tool groove 30 has a guide slope 31 on the assembly slot and / or notch 29.

[0065] In this embodiment, guide slopes 31 are provided on the assembly slot and notch 29 of the tool groove 30. The guide slopes 31 are provided so that the assembly part 33 of the tool 26 can be guided by the guide slopes 31 to be assembled on the assembly slot of the tool groove 30 and to leave the assembly slot of the tool groove 30.

[0066] The mounting slot of the tool groove 30 and the mounting part 33 of the tool 26 are both in the shape of a straight line. The two shapes match each other and fit together during assembly.

[0067] The tool holder assembly also includes a tool holder housing 32, in which a bevel gear transmission pair 34 is provided; the inner end of the tool holder drive shaft 28 is located inside the tool holder housing 32 and meshes with the bevel gear transmission pair 34; the positioning plate 27 is located on the side of the tool holder drive shaft 28 and is fixedly mounted on the tool holder housing 32.

[0068] The main housing 1 is provided with a rotating cavity 18; the tool holder box 32 is located at the opening on one side of the rotating cavity 18; the tool holder servo motor mounting bracket 35 is fixedly provided at the opening on the other side of the rotating cavity 18; the tool holder servo motor 25 is fixedly provided on the tool holder servo motor mounting bracket 35, and its power output end is driven and connected to a transmission rod 36, which passes through the rotating cavity 18 and is in transmission cooperation with the bevel gear transmission pair 34.

[0069] That is, the tool holder servo motor 25 outputs power to the bevel gear transmission pair 34 through the transmission rod 36, and the bevel gear transmission pair 34 then drives the tool holder drive shaft 28 to rotate, so that the tool 26 mounted on the tool slot 30 can rotate and the milling operation can be realized.

[0070] An extension column 37 is also provided on the tool holder servo motor mounting bracket 35. The extension column 37 extends toward the tool holder box 32 and passes through the rotating cavity 18. An assembly bracket 38 is provided on the extension column 37. The tool holder box 32 is fixedly mounted on the assembly bracket 38 to improve the assembly stability of the tool holder box 32, thereby ensuring that the tool holder drive shaft 28 can rotate stably. At the same time, the transmission rod 36 is located inside the extension column 37 to improve the compactness of the structure.

[0071] To make the rotation of the turret 2 more stable, a turret spindle 17 is sleeved on the extension column 37. The turret spindle 17 is fixedly connected to the turret 2 and a main bearing 20 is sleeved on it. The turret spindle 17 rotates in the rotating cavity 18 through the main bearing 20.

[0072] Rotary gear 5 is rotatably sleeved on extension column 37; turret servo motor 3 is driven and connected to rotary gear 5; rotary gear 5 is fixedly connected to turret spindle 17; floating gear 4 is adaptively floating and sleeved on extension column 37, and engages and locks rotary gear 5 or disengages from rotary gear 5 when floating.

[0073] In this embodiment, one side of the rotating gear 5 is fixedly connected to the turret spindle 17, and the other side is provided with a rotating tooth 6; the floating gear 4 is provided with an adaptive movable part 7 and a floating tooth 8; the main housing 1 is provided with a movable mating part 9; when the floating gear 4 moves in the direction of the rotating gear 5, it adaptively floats on the movable mating part 9 through the adaptive movable part 7, and engages with the rotating tooth 6 without clearance through the floating tooth 8, so as to achieve the angle locking of the turret 2.

[0074] By utilizing the movement of the floating gear 4, when it moves in the direction of the rotating gear 5, it can adaptively float on the movable mating part 9 through the adaptive moving part 7. This allows the floating gear 4 to adaptively move in different directions. During the adaptive movement, it can achieve backlash-free meshing with the rotating gear 6 through the floating tooth part 8, so that the turret 2 can achieve true angle locking. This avoids the problem in the prior art where the floating gear 4 can only move axially, causing the turret 2 angle to be unable to be locked, resulting in difficulty in tool changing and poor tool working stability. This ensures smooth tool changing and also improves the working stability of the tool.

[0075] Specifically, the floating chain 4 moves axially and radially on the main housing 1.

[0076] The axial movement of the floating gear 4 is achieved by the action of hydraulic oil, while the radial movement is achieved by the mating shape between the adaptive movable part 7 and the movable mating part 9. Since the floating gear 4 can move in both the axial and radial directions, when the position of the rotating tooth part 6 is fixed, the floating tooth part 8 can adaptively float and avoid collisions, ensuring that the floating tooth part 8 and the rotating tooth part 6 achieve backlash-free meshing during engagement.

[0077] The size of the movable mating part 9 is larger than the size of the adaptive movable part 7; the adaptive movable part 7 floats on the movable mating part 9 with an adaptive clearance. Because of the size difference between the movable mating part 9 and the adaptive movable part 7, a certain gap can be formed locally during use, so that the floating gear 4 and the rotating gear 5 have a non-rigid fit, increasing stability.

[0078] The adaptive active part 7 and the active mating part 9 have a conical concave-convex fit, which can further improve the stability of their use.

[0079] In this embodiment, a rotating gear 5 is fixedly connected to a rotating chainring 10 on the side facing the floating chainring 4; a rotating tooth 6 is disposed on the rotating chainring 10; a floating tooth 8 is disposed on one side of the floating chainring 4 and corresponds to the rotating tooth 6; a chainring pressure plate 11 is fixedly connected to the other side of the floating chainring 4; and an adaptive movable part 7 is disposed on the chainring pressure plate 11.

[0080] The toothed plate pressure plate 11 has a first side wing 12 extending from its periphery; the adaptive movable part 7 is axially protruding on the first side wing 12 in the direction of the turret 2; the movable mating part 9 is axially recessed on the main housing 1 in the direction of the turret 2 and corresponds to the adaptive movable part 7.

[0081] The main housing 1 is provided with an oil passage hole 13 and an oil cavity 14; the oil cavity 14 is connected to the oil passage hole 13; the outer periphery of the gear plate pressure plate 11 is also extended with a second side wing 15, and a piston 16 is axially arranged on the second side wing 15 in the direction of the turret 2, and the piston 16 is placed in the oil cavity 14.

[0082] In this embodiment, the outer periphery of the tooth plate 11 has two first side wings 12 and two second side wings 15. The two first side wings 12 are symmetrically arranged, and the two second side wings 15 are symmetrically arranged, that is, the two first side wings 12 and the two second side wings 15 are in a cross shape.

[0083] The adaptive active part 7 is a conical protrusion, and the active mating part 9 is a conical concave hole. The conical protrusion and the conical concave hole are connected in a conical convex-concave shape.

[0084] The use of symmetrical oil passage drive and conical concave-convex interlocking ensures that the axial and radial movements of the floating sprocket 4 and the sprocket pressure plate 11 will not have any deviation problems, so as to truly achieve the angle locking of the turret 2.

[0085] The oil passage 13 is connected to the external hydraulic oil supply end.

[0086] When the external hydraulic oil supply end fills the oil chamber 14 with oil through the oil passage hole 13, the floating toothed plate 4 moves toward the rotating gear 5 under the push of the oil pressure. At the same time, it floats adaptively on the movable mating part 9 through the adaptive movable part 7 and meshes with the rotating tooth part 6 without clearance through the floating tooth part 8.

[0087] When the external hydraulic oil supply end draws hydraulic oil from the oil chamber 14 through the oil passage hole 13, the floating toothed plate 4 moves away from the rotating gear 5, and at the same time, the adaptive moving part 7 leaves the moving mating part 9 and disengages from the rotating toothed part 6 through the floating toothed part 8.

[0088] In this embodiment, a fixing ring 19 is provided at one end of the turret spindle 17 and is fixedly connected to the turret 2 through the fixing ring 19. A main bearing 20 is sleeved in the middle of the turret spindle 17 and rotates in the rotating cavity 18 through the main bearing 20. A locking member 21 is provided at the other end of the turret spindle 17 and the main bearing 20 is limited and assembled through the locking member 21.

[0089] During assembly, the main bearing 20 is sleeved on the middle of the turret spindle 17 and one side is limited and rests against the retaining ring 19. The locking member 21 is then assembled to the other end of the turret spindle 17 through this thread and is limited and rests against the other side of the main bearing 20.

[0090] To ensure more stable assembly of the turret servo motor 3 and a more rational drive between it and the rotating gear 5, a transmission gear cavity 22 is provided on the side of the rotating cavity 18. A transmission gear 23 is provided inside the transmission gear cavity 22, and the transmission gear 23 meshes with the rotating gear 5 for transmission. A turret servo motor mounting bracket 24 is fixedly installed at the opening of the transmission gear cavity 22. The turret servo motor 3 is a servo motor and is fixedly installed on the turret servo motor mounting bracket 24. The power output end of the turret servo motor 3 passes through the turret servo motor mounting bracket 24 and is driven and connected to the transmission gear 23.

[0091] When tool 26 needs to be changed, the floating gear 4 moves away from the rotating gear 5, and the floating tooth 8 disengages from the rotating tooth 6. Then, the turret servo motor 3 drives the transmission gear 23 to rotate in the transmission gear cavity 22. The transmission gear 23 drives the rotating gear 5 to rotate. When the rotating gear 5 rotates, it also drives the turret spindle 17 to rotate in the rotating cavity 18 through the main bearing 20, thereby driving the turret 2 to rotate relative to the main housing 1.

[0092] When milling is required, the floating gear 4 moves toward the rotating gear 5, and the floating tooth 8 meshes with the rotating tooth 6 without clearance to lock the angle of the turret 2. Then the tool holder servo motor 25 works to drive the tool holder drive shaft 28 to rotate and cause the tool 26 mounted on the tool slot 30 to rotate to achieve milling.

[0093] In this embodiment, the turret 2 is annular, and its outer peripheral sidewall is provided with a number of mounting ports 39 for assembling the cutting tools 26, so that the turret 2 can be equipped with different cutting tools 26 for the tool holder drive shaft 28 to assemble.

[0094] In this embodiment, the tool holder assembly rotates inside the turret 2 and can be assembled with different cutting tools 26 according to the actual machining conditions.

[0095] The above describes the preferred embodiments of the present invention, illustrating and describing the basic principles, main features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as defined by the appended claims and their equivalents.
