Description

Technical Field

[0001] The invention belongs to the technical field of power turret equipment, and in particular relates to a turret device which can be equipped with multiple cutting tools and can perform independent milling. Background Art

[0002] As one of the important hardware in CNC lathes, the future development trend of tool turrets is high efficiency, high precision, low failure rate and easy use. The functions realized by the servo tool turret structure currently used are relatively simple. It mainly uses the servo motor to drive the gear to rotate and realize the rotation of the cutter head to change the tool position. If a plane needs to be machined around the workpiece, the workpiece needs to be disassembled and then fixed to the milling machine for processing using the milling cutter. The process of disassembling, installing and setting the tool will take a long time, and the processing is very inconvenient. However, in order to achieve complex processing, a power milling axis mechanism is often added externally in practice, but it takes up a large space on the machine tool and is not easy to use. Summary of the Invention

[0003] The object of the present invention is to provide a turret device that can accommodate multiple cutting tools and can perform independent milling in order to solve the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions: a turret device capable of accommodating multiple tools and independently milling, comprising a turret case, a turret body movably mounted on one end of the turret case, a tool-changing hydraulic control mechanism disposed between the turret body and the turret case that can circumferentially lock or circumferentially movably connect the turret body and the turret case, a tool-changing drive mechanism disposed between the turret body and the turret case that can drive the turret body to circumferentially rotate relative to the turret case when the turret body and the turret case are circumferentially movably connected, a milling disk movably mounted on one end of the turret case away from the turret body, and a milling drive mechanism disposed on the turret case that can independently drive the milling disk to rotate. The tool-changing hydraulic control mechanism and the milling drive mechanism enable the milling disk and the turret body to operate independently, thereby improving work efficiency.

[0005] In the aforementioned turret device capable of accommodating multiple tools and independently milling, the milling drive mechanism includes a milling spindle that rotates within the turret housing. One end of the milling spindle extends through the turret housing and the turret body and is connected to the milling disc. A milling servo motor is provided at the end of the turret housing distal from the turret body. This milling servo motor is connected to the other end of the milling spindle via a milling reducer secured to the outside of one end of the turret housing. The milling disc is directly connected to the milling servo motor via the milling spindle, employing a direct drive mechanism that effectively improves cutting torque and transmission efficiency.

The spindle head is located within the turret body, and the stabilizing bearing serves as a decoupling mechanism. When the milling spindle rotates, the stabilizing bearing ensures that the turret body remains stationary without being affected. Rotation of the turret body also does not affect the milling spindle, rendering the milling disc completely independent of the turret body.

[0007] In the aforementioned turret device capable of accommodating multiple tools and independently performing milling operations, the tool change drive mechanism includes a tool change spindle located within the turret housing and movably mounted circumferentially outside the milling spindle. One end of the tool change spindle is fixedly connected to the turret body, and the other end is connected to a tool change drive assembly mounted on the turret housing. The turret body is rotated by the tool change spindle in conjunction with the tool change drive assembly. The tool change spindle is located outside the milling spindle, so that rotation of the tool change spindle or milling spindle does not affect the other.

[0008] The tool turret of the present invention is a kind of tool turret device that can be equipped with multiple tools and can mill independently, the tool changing hydraulic control mechanism includes a three-piece end gear disk assembly located in the tool turret box and capable of circumferentially positioning or separating the tool turret box and the tool turret body, and the three-piece end gear disk assembly is connected to the tool changing hydraulic drive assembly, and the three-piece end gear disk assembly is used to effectively ensure the precise indexing and repeat positioning accuracy of the tool, the three-piece end gear disk assembly includes an axially movable sleeve arranged on the tool changing spindle near the end of the tool turret body and located in the tool turret box, the end of the tool changing spindle connected to the tool turret body is provided with an inner gear disk located on one side of the movable gear disk, the circumferential outer side of the inner gear disk is provided with an outer gear disk connected to the tool turret box, the movable gear disk has a plurality of movable teeth circumferentially at one end near the inner gear disk or the outer gear disk, the inner gear disk has a plurality of inner teeth circumferentially at one end near the movable gear disk, and the outer gear disk has a plurality of outer teeth circumferentially at one end near the movable gear disk, and the movable teeth are simultaneously engaged with or separated from the inner teeth and the outer teeth. The movable gear disc is used to limit the circumferential rotation of the inner gear disc, and the outer gear disc cooperates with the movable gear disc to fix the inner gear disc. The inner gear disc is used to connect the tool change spindle and the turret body. The sum of the width of the inner teeth and the outer teeth is equal to the thickness of the movable teeth. When the movable teeth are separated from the inner teeth and the outer teeth, the turret body starts to rotate. When the movable teeth are engaged with the inner teeth and the outer teeth, the turret body stops rotating. The movable gear disc and the outer gear disc are both in a circumferentially stationary state, and the inner gear disc rotates circumferentially driven by the tool change spindle.

[0009] In the above-mentioned turret device that can be equipped with multiple tools and can mill independently, the turret body has a positioning hole for inserting one end of the inner gear disc at one end close to the turret box, the inner circumferential side of the inner gear disc has an inner gear disc inner positioning part extending to the end face of the tool changing spindle, and the inner gear disc inner positioning part is fixedly connected to the end of the tool changing spindle by a plurality of first positioning bolts, the outer circumferential side of the inner gear disc has an inner gear disc outer positioning part extending to one end of the turret body and located outside the positioning hole, and the inner gear disc outer positioning part is fixedly connected to the turret body by a plurality of second positioning bolts, the outer circumferential side of the outer gear disc is provided with an outer gear disc connecting ring extending to the outside of the turret box, and the outer gear disc connecting ring is fixedly connected to the turret box by a plurality of third positioning bolts, and a water dividing ring is provided between the turret box and the turret body, which is sleeved on the outer gear disc connecting ring and the circumferential outside of the inner gear disc outer positioning part. The turret body is connected to the inner gear disc's outer locating portion via a locating hole. The inner gear disc is connected to the tool change spindle via the inner gear disc's inner locating portion. Rotation of the tool change spindle drives the turret body. The outer gear disc is connected to the turret case via an outer gear disc connecting ring. This way, the outer gear disc is fixed and secures the inner gear disc with the movable gear disc. The water divider provides a certain degree of cooling protection and prevents foreign matter from entering between the inner and outer gear discs.

[0010] In the above-mentioned turret device capable of accommodating multiple tools and independently milling, the tool-changing hydraulic drive assembly includes a cutter disc locking oil pressure port and a cutter disc releasing oil pressure port, which are arranged at one end of the turret box away from the turret body. An oil chamber is provided on the circumferential outer side of the movable toothed disc and the circumferential inner side of the turret box, and the cutter disc locking oil pressure port and the cutter disc releasing oil pressure port are respectively connected to the oil chamber via an oil circuit. An elastic reset mechanism is provided on the tool-changing spindle to enable the movable toothed disc to maintain its movement tendency toward the inner and outer toothed discs. Hydraulic oil is added to the oil chamber from the cutter disc locking oil pressure port. The increased pressure in the oil chamber pushes the movable toothed disc backward, separating the movable toothed disc from the inner and outer toothed discs, causing the inner toothed disc to begin rotating.

The stabilizing ring is circumferentially connected to the inner side of the turret housing. The end of the tool change spindle away from the turret body includes an annular transmission portion, and a needle roller bearing is disposed between the stabilizing ring and the annular transmission portion and / or between the stabilizing ring and the tool change spindle. When the movable toothed disc moves rearward, it is pushed by hydraulic oil, and the pressure spring is in a tightened state. When the hydraulic oil is withdrawn, the pressure spring begins to reset and pushes the movable toothed disc forward, and the needle roller bearing reduces friction between the tool change spindle and the stabilizing ring.

[0012] In the aforementioned turret device capable of accommodating multiple tools and independently milling, the tool change drive assembly includes a turret case connection base disposed on the outside of one end of the turret case, away from the turret body. A tool change servo motor is mounted on the turret case connection base. The output shaft of the tool change servo motor passes through the turret case connection base and is connected to a drive gear. A transmission shaft, parallel to the output shaft of the tool change servo motor, is provided for rotation between the turret case connection base and the turret case. A first linkage gear meshing with the drive gear is provided at one end of the transmission shaft, and a second linkage gear meshing with the transmission gear on the circumferential outer side of the annular transmission portion is provided at the other end. The turret body is independently controlled by the tool change servo motor and connected to a tool change spindle. The tool change servo motor is connected to the transmission gear of the tool change spindle via the transmission shaft, the first linkage gear, and the second linkage gear, thereby achieving rotation of the turret body.

[0013] In the aforementioned turret device capable of accommodating multiple tools and independently milling, the turret housing connection base is L-shaped, and the milling speed reducer is disposed on the turret housing connection base below one end of the tool-changing servo motor. A stabilizing base connected to the turret housing connection base is provided within the turret housing, and the milling spindle rotates through the stabilizing base. Several tool loading stations are mounted on the turret body, and the milling disk has a diameter smaller than that of the turret body.

[0015] The device uses two motors to control the turret body and milling disk respectively, realizing independent operation of the turret body and the milling disk. At the same time, by installing a stabilizing bearing in the turret body, the friction between the tool changing spindle and the milling spindle is reduced, the transmission efficiency is improved, and the three-piece end gear disk assembly is used to effectively ensure the precise indexing and repeatable positioning accuracy of the surrounding tools.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-7As shown, a turret device capable of holding multiple tools and independently milling includes a turret case 1, a turret body 2 movably mounted at one end of the turret case 1, a tool-changing hydraulic control mechanism 3 disposed between the turret body 2 and the turret case 1, capable of circumferentially locking or circumferentially movably connecting the turret body 2 and the turret case 1, and a tool-changing drive mechanism 4 disposed between the turret body 2 and the turret case 1, capable of driving the turret body 2 to rotate circumferentially relative to the turret case 1 when the turret body 2 and the turret case 1 are circumferentially movably connected, a milling disk 21 movably mounted at one end of the turret case 1 away from the turret body 2, and a milling drive mechanism 5 disposed on the turret case 1, capable of independently rotating the milling disk 21. The tool-changing hydraulic control mechanism 3 and the milling drive mechanism 5 enable the milling disk 21 and the turret body 2 to operate independently, thereby improving work efficiency.

[0026] like Figure 3 As shown, the milling drive mechanism 5 includes a milling spindle 51 that rotates and passes through the turret housing 1. One end of the milling spindle 51 passes through the turret housing 1 and the turret body 2 in sequence and is connected to the milling disk 21. A milling servo motor 52 is installed at the end of the turret housing 1 away from the turret body 2. The milling servo motor 52 is connected to the other end of the milling spindle 51 through a milling reducer 53 fixed to the outside of one end of the turret housing 1. The milling disk 21 is directly connected to the milling servo motor 52 through the milling spindle 51, adopting a direct connection and direct drive method, which effectively improves cutting torque and transmission efficiency.

[0027] like Figure 5 As shown, one end of the milling spindle 51 has a spindle head 54 located inside the turret body 2, and a stabilizing bearing 55 is provided between the circumferential outer side of the spindle head 54 and the circumferential inner side of the turret body 2. One end of the spindle head 54 is provided with a spindle connecting portion 56 extending to the outside of the turret body 2, and the spindle connecting portion 56 is connected to the center of the milling disk 21 via a number of connecting bolts. The spindle head 54 is located inside the turret body 2, and the stabilizing bearing 55 serves as a separation. When the milling spindle 51 rotates, the turret body 2 is not affected by the stabilizing bearing 55 and remains stationary. When the turret body 2 rotates, it does not affect the milling spindle 51, making the milling disk 21 completely independent of the turret body 2.

[0028] Combine Figure 1 and Figure 3 As shown, the tool change drive mechanism 4 includes a tool change spindle 41 located within the turret housing 1 and movably mounted on the circumferential outside of the milling spindle 51. One end of the tool change spindle 41 is fixedly connected to the turret body 2, and the other end is connected to the tool change drive assembly 8 disposed on the turret housing 1. The turret body 2 rotates via the tool change spindle 41 in conjunction with the tool change drive assembly 8. The tool change spindle 41 is located outside the milling spindle 51, so that when the tool change spindle 41 or the milling spindle 51 rotates, it will not affect the other.

[0029] Combine Figure 6 and Figure 7As shown, the tool-changing hydraulic control mechanism 3 includes a three-piece end gear disc assembly 31 located in the turret box 1 and capable of circumferentially positioning or separating the turret box 1 and the turret body 2, and the three-piece end gear disc assembly 31 is connected to the tool-changing hydraulic drive assembly 6. The use of the three-piece end gear disc assembly 31 effectively ensures the precise indexing and repeat positioning accuracy of the tool. The three-piece end gear disc assembly 31 includes an axially movable sleeve on the end of the tool-changing spindle 41 close to the turret body 2 and located in the turret box 1. The tool-changing spindle 41 is connected to the turret body 2. One end of the gear disc 33 is provided with an inner gear disc 33 located on one side of the movable gear disc 32, and an outer gear disc 34 connected to the turret box 1 is provided on the outer side of the inner gear disc 33. The movable gear disc 32 has a plurality of movable teeth 35 on the circumference of one end close to the inner gear disc 33 or the outer gear disc 34. The inner gear disc 33 has a plurality of inner teeth 36 on the circumference of one end close to the movable gear disc 32, and the outer gear disc 34 has a plurality of outer teeth 37 on the circumference of one end close to the movable gear disc 32, and the movable teeth 35 are engaged with or separated from the inner teeth 36 and the outer teeth 37 at the same time. The movable toothed disc 32 is used to limit the circumferential rotation of the inner toothed disc 33, and the outer toothed disc 34 cooperates with the movable toothed disc 32 to fix the inner toothed disc 33. The inner toothed disc 33 is used to connect the tool changing spindle 41 and the turret body 2. The sum of the widths of the inner teeth 36 and the outer teeth 37 is equal to the thickness of the movable teeth 35. When the movable teeth 35 are separated from the inner teeth 36 and the outer teeth 37, the turret body 2 starts to rotate. When the movable teeth 35 are engaged with the inner teeth 36 and the outer teeth 37, the turret body 2 stops rotating. The movable toothed disc 32 and the outer toothed disc 34 are both in a circumferentially stationary state. The inner toothed disc 33 rotates circumferentially driven by the tool changing spindle 41, and an auxiliary bearing is installed between the movable toothed disc 32 and the turret box 1, which plays a certain supporting role.

[0030] like Figure 3When the tool is tightened, the cam 331 is tightened and the cam 332 is tightened, so that the tool is tightened. When the tool is tightened, the cam 332 is tightened and the cam 332 is tightened. When the tool is tightened, the cam 332 is tightened and the cam 332 is tightened. The turret body 2 is connected to the inner gear disc outer positioning portion 332 of the inner gear disc 33 through the positioning hole 22. The inner gear disc 33 is connected to the tool change spindle 41 through the inner gear disc inner positioning portion 331. In this way, the rotation of the tool change spindle 41 drives the turret body 2 to rotate. The outer gear disc 34 is connected to the turret case 1 through the outer gear disc connecting ring 341. In this way, the outer gear disc 34 is in a fixed state and cooperates with the movable gear disc 32 to fix the inner gear disc 33. The water diverter ring 26 provides a certain cooling protection function and prevents foreign matter from entering between the inner gear disc 33 and the outer gear disc 34.

[0031] The tool change hydraulic drive assembly 6 includes a cutter disc locking oil pressure port 61 and a cutter disc release oil pressure port 62 provided at one end of the turret case 1 away from the turret body 2. An oil chamber 63 is provided on the circumferential outer side of the movable gear disc 32 and the circumferential inner side of the turret case 1. The cutter disc locking oil pressure port 61 and the cutter disc release oil pressure port 62 are respectively connected to the oil chamber 63 through oil passages. An elastic reset mechanism 7 is provided on the tool change spindle 41 to enable the movable gear disc 32 to maintain a movement trend toward the inner gear disc 33 and the outer gear disc 34. Hydraulic oil is added to the oil chamber 63 from the cutter disc locking oil pressure port 61. The pressure in the oil chamber 63 increases, pushing the movable gear disc 32 backward. The movable gear disc 32 is then separated from the inner gear disc 33 and the outer gear disc 34. In this way, the inner gear disc 33 begins to rotate. The hydraulic oil is then released through the cutter disc release oil pressure port 62, and the movable gear disc 32 re-engages with the inner gear disc 33 and the outer gear disc 34.

[0032] like Figure 6As shown, the elastic reset mechanism 7 includes a stabilizing ring 71 which is sleeved on the tool changing spindle 41 and is located at one end of the movable gear disc 32 away from the inner gear disc 33 and the outer gear disc 34. An annular gap 72 is formed between the stabilizing ring 71 and the movable gear disc 32. A plurality of pressure springs 73 are circumferentially provided in the annular gap 72, and one end of the pressure spring 73 acts on the stabilizing ring 71, and the other end acts on the movable gear disc 32. The stabilizing ring 71 is connected to the inner side of the turret box 1 in the circumferential direction, and the end of the tool changing spindle 41 away from the turret body 2 has an annular transmission part 74, and a needle bearing 75 is provided between the stabilizing ring 71 and the annular transmission part 74 and / or between the stabilizing ring 71 and the tool changing spindle 41. When the movable gear disc 32 moves backward, it is pushed by the hydraulic oil, and the top pressure spring 73 is in a tightened state. When the hydraulic oil is withdrawn, the top pressure spring 73 begins to reset and pushes the movable gear disc 32 forward. The needle roller bearing 75 reduces the friction between the tool changing spindle 41 and the stabilizing ring 71, and an auxiliary bearing is installed between the stabilizing ring 71 and the turret box 1, which plays a certain supporting role.

[0033] like Figure 4 As shown, the tool change drive assembly 8 includes a turret case connection base 81, which is arranged on the outside of the end of the turret case 1 away from the turret body 2. A tool change servo motor 82 is installed on the turret case connection base 81. The output shaft 88 of the tool change servo motor 82 passes through the turret case connection base 81 and is connected to a drive gear 83. A transmission shaft 84, which is arranged parallel to the output shaft 88 of the tool change servo motor 82, is rotatably provided between the turret case connection base 81 and the turret case 1. The transmission shaft 84 has a first linkage gear 85 at one end that meshes with the drive gear 83, and a second linkage gear 86 at the other end that meshes with the transmission gear 76 on the circumferential outer side of the annular transmission portion 74. The turret body 2 is independently controlled by the tool change servo motor 82. The turret body 2 is connected to the tool change spindle 41. The tool change servo motor 82 is connected to the transmission gear 76 of the tool change spindle 41 via the transmission shaft 84, the first linkage gear 85, and the second linkage gear 86, thereby achieving rotation of the turret body 2.

[0034] Combine Figure 2 and Figure 3 As shown, the turret box connection base 81 is L-shaped, and the milling cutter box 53 is arranged on the turret box connection base 81 below one end of the tool change servo motor 82. A stabilizing base 87 connected to the turret box connection base 81 is provided in the turret box 1, and the milling spindle 51 rotates through the stabilizing base 87. Several tool loading stations are installed on the turret body 2, and the diameter of the milling disk 21 is smaller than that of the turret body 2. Several milling cutters are also installed on the outside of the milling disk 21.

[0035] The principle of this embodiment is:

[0036] The output shaft 88 of the tool changing servo motor 82 is connected to the tool changing spindle 41 through the transmission shaft 84, and the tool changing spindle 41 is connected to the turret body 2 through the three-piece end gear disk assembly 31. The milling servo motor 52 is connected to the milling spindle 51 through the milling reducer 53, and the milling spindle 51 is connected to the milling disk 21. The big head end 54 of the milling spindle 51 moves in the turret body 2 through the stabilizing bearing 55. When the milling spindle 51 and the tool changing spindle 41 rotate, they will not affect each other. At the same time, the turret body 2 and the milling disk 21 are controlled by two different motors to achieve independent operation, thereby improving work efficiency.
