Description

Technical Field

[0001] The present invention relates to the technical field of turrets, and in particular to a single-servo powered turret. Background Art

[0002] A CNC lathe is a powerful precision machine tool. In the working area of the machine, a variety of cutting tools such as turning tools, milling cutters, drills, taps, etc. can be installed in the turret according to needs and purposes. These tools are controlled to feed and retract the workpiece according to a predetermined program to complete the cutting work.

[0003] Most of the existing turrets are dual-servo turrets, where one servo controls the rotation of the tool disc to change the tool, and the other servo drives the tool rotation. The dual-servo turret uses two servo drives, resulting in high costs. The overall size of the turret is also large, requiring a larger installation space and poor adaptability.

[0004] Chinese patent number CN102615298B discloses a single-servo powered toolholder based on a BMT cutterhead. A servo motor drives the BMT cutterhead through a spur gear system mounted on an intermediate shaft. This drives the live tool through a spur and bevel gear system mounted on the intermediate shaft. Power switching is achieved by a clutch mechanism involving a spur gear mounted on the power input shaft and a hydraulic shift fork mechanism. However, in this structure, the shift fork mechanism requires a separate hydraulic system to drive it. This additional hydraulic system increases the overall size of the motor and the manufacturing cost of the toolholder. Furthermore, the internal structure of this structure is relatively complex, making it difficult to assemble.

[0005] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Summary of the Invention

DETAILED DESCRIPTION

[0028] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0029] like Figure 1-9As shown, a single-servo powered turret includes a cutter disc 11, a mounting base 12, a locking plate 21, a movable gear disc 22, a fixed gear disc 23, a main shaft 31, a transmission shaft 32, a drive shaft 33, a switching sleeve 4, a shift fork plate 51, and a connecting rod 52. The fixed gear disc 23 is locked to the mounting base 12, and the movable gear disc 22 is connected to the fixed gear disc 23 via a cross roller bearing sleeve. The cross roller bearing connection can withstand large axial and radial loads and can further simplify and reduce the connection structure between the fixed gear disc 23 and the movable gear disc 22, making the connection structure more compact. The side of the movable gear disc 22 is locked to the cutter disc 11. A fixed sleeve 6 is fixedly connected to the mounting base 12, and a locking disc 21 is sleeved on the fixed sleeve 6. The locking disc 21 is arranged on the side of the fixed gear disc 23 and the movable gear disc 22. The side wall of the locking disc 21 near the movable gear disc 22 is provided with a first locking tooth, and the side walls of the fixed gear disc 23 and the movable gear disc 22 near the locking disc 21 are provided with a second locking tooth. The first locking tooth and the second locking tooth can be locked and meshed with each other. The locking disc 21 can be driven to move horizontally by air pressure or a hydraulic system. When the locking disc 21 is in contact with the fixed gear disc 23 and the movable gear disc 22, the movable gear disc 22 is locked and fixed. At this time, the cutter disc 11 cannot rotate, and the tool in the cutter disc 11 can rotate for processing. When the locking disc 21 is separated from the fixed gear disc 23 and the movable gear disc 22, the movable gear disc 22 is released. At this time, the movable gear disc 22 can drive the cutter disc 11 to rotate for tool changing.

[0030] The drive shaft 33 is rotatably connected to the mounting base 12 via a bearing. An outer ring gear is provided on the outer circumferential sidewall of the movable gear plate 22. The front end of the drive shaft 33 is provided with a gear that meshes with the outer ring gear of the movable gear plate 22. The gear ratio between the gear at the front end of the drive shaft 33 and the outer ring gear of the movable gear plate 22 needs to be adjusted and set according to the tool. In this embodiment, the cutter disc 11 has eight workstations, so the gear ratio between the gear at the front end of the drive shaft 33 and the outer ring gear of the movable gear plate 22 is 1:8. The main shaft 31 is vertically arranged in the cutter disc 11 and is rotatably connected. Specifically, the cutter disc 11 is provided with an inner mounting seat 111, which is locked and fixed to the side wall of the fixed sleeve 6. The main shaft 31 is rotatably connected to the interior of the inner mounting seat 111 via a bearing. The lower end of the main shaft 31 is provided with a slot. Several cutting drums are mounted on the cutterhead 11. A straight-line boss is provided at one end of the cutting drum near the spindle 31. The boss engages with a straight-line groove, allowing the spindle 31 to drive the cutting drums to rotate and perform cutting operations. A drive shaft 32 rotates within a fixed sleeve 6. A bevel gear is provided at the front end of the drive shaft 32, through which the drive shaft 32 and the spindle 31 are driven. A servo motor 7 is mounted on the mounting base 12. A switching sleeve 4 is splined to the output shaft of the servo motor 7. The switching sleeve 4 has a front tooth end 41, a rear tooth end 42, and an annular groove 43. A mating cavity 321 is provided at the rear end of the drive shaft 32. An inner ring gear is provided on the inner wall of the mating cavity 321. The front tooth end 41 can extend into the mating cavity 321 and connect to the inner ring gear via a gear transmission. The rear tooth end 42 is connected to the drive shaft 33 via a reduction mechanism. A shift fork plate 51 is nested within the annular groove 43. The ends of a connecting rod 52 are fixedly connected to the locking plate 21 and the shift fork plate 51, respectively.

[0031] To facilitate assembly and disassembly of the shift fork plate 51, the shift fork plate 51 comprises a main plate body 511 and a locking plate 512. The main plate body 511 is annular in shape, with a connecting boss 513 provided on its outer circumference. The end of the connecting rod 52 is embedded in the connecting boss 513 and secured by screws. A mating groove 514 is defined on the side of the main plate body 511. The locking plate 512 is semi-circular in shape and locked within the mating groove 514. The inner side of the locking plate 512 is engaged with the annular groove 43. The outer side of the locking plate 512 is provided with a mating boss 515 that engages with the mating groove 514. With this structure, during assembly, the locking plates 512 are symmetrically placed into the mating grooves 514 for mating. The main plate body 511 is then locked and secured to the two locking plates 21, securing the shift fork plate 51 in the mating grooves 514 and making assembly and disassembly more convenient.

[0032] In this embodiment, a connecting sleeve 71 is sleeved onto the output shaft of the servo motor 7. The switching sleeve 4 is sleeved on the front end of the connecting sleeve 71 and is driven by a spline. A stop pin 72 and a stop sleeve 73 are provided within the connecting sleeve 71. The inner sidewall of the switching sleeve 4 is provided with a stop groove 44. The stop sleeve 73 has a stop boss 731 that engages within the stop groove 44. The stop boss 731 is slidably connected within the stop groove 44 via a retaining ring. The front end of the stop pin 72 passes through the stop sleeve 73 and is locked to the drive shaft 32. A spring 74 is sleeved around the stop pin 72, and the ends of the spring 74 respectively abut against the drive shaft 32 and the stop sleeve 73. When the cutterhead 11 is switched, the shift fork 51 and the switching sleeve 4 move leftward, driving the stop sleeve 73 with them, which compresses the spring 74. When cutting, the fork plate 51 drives the switching sleeve 4 to move to the right. At this time, the limiting sleeve 73 continues to drive the switching sleeve 4 to move slightly to the right by a short distance under the action of the spring 74. The front tooth end 41 of the switching sleeve 4 cooperates with the transmission shaft 32 for transmission, and there is a clearance between the front and rear side walls of the fork plate 51 and the side walls of the annular groove 43. This can effectively prevent the connecting sleeve 71 from rubbing against the fork plate 51 during high-speed rotation, avoid high temperature of the connecting sleeve 71, make the connecting sleeve 71 rotate more smoothly, and improve the service life of the connecting sleeve 71.

[0033] In this embodiment, an outer shell cover 13 and a reduction mechanism are also provided on the mounting base 12. The reduction mechanism includes a transmission sleeve 81, a first transmission gear 82, a second transmission gear 83 and a connecting seat 84. The transmission sleeve 81 is rotatably connected in the outer shell cover 13 through a bearing. The connecting sleeve 71 passes through the inside of the transmission sleeve 81. The inner side wall of the front end of the transmission sleeve 81 is provided with an inner gear ring that meshes with the rear tooth end 42 for transmission. The outer side wall of the front end of the transmission sleeve 81 is provided with an outer gear ring that meshes with the first transmission gear 82 for transmission. The connecting seat 84 is fixed to the mounting base 12. The first transmission gear 82 is sleeved on the rotating shaft of the connecting seat 84 for rotational connection. The second transmission gear 83 is sleeved on the drive shaft 33. The first transmission gear 82 and the second transmission gear 83 are meshed with each other for transmission. With the above structure, when switching the cutterhead 11, the switching sleeve 4 moves forward, and the rear tooth end 42 of the switching sleeve 4 meshes with the inner gear ring at the front end of the transmission sleeve 81. The servo motor 7 drives the connecting sleeve 71 to rotate, which in turn drives the switching sleeve 4, and then drives the transmission sleeve 81. The transmission sleeve 81 drives the drive shaft 33 through the first transmission gear 82 and the second transmission gear 83. The reduction gear transmission by the above reduction mechanism can ensure that the drive shaft 33 rotates one circle after the output shaft of the drive motor rotates a fixed number of times, and the drive shaft 33 can drive the cutterhead 11 to rotate by one working angle.

[0034] In this embodiment, the drive shaft 33 is connected to the outer housing 13 via a locking sleeve. This locking sleeve connection facilitates adjustment of the drive shaft 33's angle, ensuring that the drive shaft 33 remains parallel to the power output shaft of the servo motor 7, ensuring smooth transmission of the servo motor 7's power to the drive shaft 3. A detection plate 331 is also provided at the rear end of the drive shaft 33. The outer circumference of the detection plate 331 is provided with an outwardly protruding detection boss 332. The outer housing 13 is provided with a first sensor 333 that senses the detection boss 332. Each time the cutterhead 11 switches between workstations, the detection plate 331 and the drive shaft 33 rotate one revolution. The first sensor 333 senses the detection boss 332, ensuring the correct rotation angle of the drive shaft 33. A detection rod 521 is connected to the rear end of the connecting rod 52. A second sensor 522 is provided on the outer housing 13 to sense the detection rod 521. The second sensor 522 senses the extension and contraction of the detection rod 521, thereby determining the position and status of the locking disk 21.

[0035] More specifically, in order to drive the locking disk 21 to move smoothly, in this embodiment, the locking disk 21 is driven to move by the air pressure system, the fixed sleeve 6 is provided with a truncated cone portion 61, the locking disk 21 is provided with a receiving groove for the truncated cone portion 61 to be embedded in the sliding, a locking air cavity 62 is formed between the receiving groove and the truncated cone portion 61, and a loosening air cavity 63 is formed between the fixed tooth plate 23 and the locking disk 21. The mounting base 12 is provided with a first air inlet hole 121, a second air inlet hole 122, a first air guide hole 123, a second air guide hole 124, and a first flow channel 1 25 and a second flow channel 126. The first air inlet 121 and the first air guide hole 123 are connected through the first flow channel 125, and the second air inlet 122 and the second air guide hole 124 are connected through the second flow channel 126. The fixed sleeve 6 is provided with a first air outlet 64 and a second air outlet 65. One end of the first air outlet 64 is connected to the first air guide hole 123 and the other end is connected to the relaxation air cavity 63. One end of the second air outlet 65 is connected to the second air guide hole 124 and the other end is connected to the locking air cavity 62. When the cutter head 11 of the present invention rotates, gas enters from the first air inlet 121, flows through the first flow channel 125 and the first air guide hole 123, enters the first air outlet 64, and then enters the relaxation air cavity 63 from the first air outlet 64, increasing the air pressure in the relaxation air cavity 63, thereby pushing the locking disc 21 to move leftward. When the present invention is performing cutting work, gas enters from the second air inlet 122, flows through the second flow channel 126 and the second air guide hole 124, enters the second air outlet 65, and enters the locking air cavity 62 from the second air outlet 65, increasing the air pressure in the locking air cavity 62, pushing the locking disk 21 to move to the right.

[0036] More preferably, a locking pin 211 is provided at the front end of the locking disk 21, which is fixedly connected to the locking disk 21 via a T-slot. A locking hole 311 is provided on the spindle 31 for engaging with the locking pin 211. When the cutter head 11 rotates, the locking disk 21 moves leftward, driving the locking pin 211 to insert into the locking hole 311, thereby locking the spindle 31 and preventing it from rotating, thereby achieving precise orientation of the spindle 31.

[0037] The working principle of the present invention is that when the present invention performs cutting processing, the pneumatic system drives the locking plate 21 to approach the movable gear plate 22 and the fixed gear plate 23, so that the locking plate 21 locks the movable gear plate 22 to fix the cutter disc 11. At this time, the connecting rod 52 moves backward under the drive of the locking plate 21, thereby pushing the fork plate 51 and driving the switching sleeve 4 to translate backward along the axis, so that the front tooth end 41 of the switching sleeve 4 engages with the internal gear ring in the matching cavity 321 of the transmission shaft 32. The drive motor then drives the connecting sleeve 71 and the switching cutter cylinder to rotate, driving the transmission shaft 32 to rotate. The transmission shaft 32 drives the main shaft 31 to rotate through the bevel gear to perform cutting. When the present invention needs to rotate the cutter disc 11 to switch the tool, the pneumatic system drives the locking disc 21 away from the movable sprocket disc 22 and the fixed sprocket disc 23, and the connecting rod 52 follows the locking disc 21 to move forward, thereby driving the fork disc 51 and the switching sleeve 4 to translate forward along the axial direction, and the rear tooth end 42 of the switching sleeve 4 engages with the transmission sleeve 81 for transmission, and drives the drive shaft 33 to rotate through the reduction mechanism, and the drive shaft 33 drives the movable sprocket disc 22 to rotate through the gear, and then drives the cutter disc 11 to rotate to complete the tool changing action.

[0038] Compared with the prior art, the present invention offers the following advantages: by switching the output transmission direction of the servo motor via a shift fork and a switching sleeve, a single servo motor is required to achieve both tool change by rotating the cutterhead and rotary cutting by the tool. This significantly reduces the manufacturing cost of the tool turret and its overall size, facilitating installation and enhancing its applicability. Furthermore, the present invention utilizes only a pneumatic system to simultaneously switch the locking state of the cutterhead and the output transmission direction of the servo motor, resulting in a compact and simple structure that facilitates assembly of the entire machine.

[0039] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
