Description

Single servo motor powered turret Technical Field

[0001] This application relates to the field of power turret technology, and in particular to a single servo motor power turret. Background Technology

[0002] A power turret is a device with a power source that can independently provide main motion and feed motion to the cutting tool, thereby completing machining operations such as milling, drilling, and drilling. It can perform multiple machining operations on the same machine tool, such as turning, drilling, tapping, end face cutting, side grooving, side milling, angle drilling, and curve milling, which greatly reduces production steps and cumulative tolerances.

[0003] The powered turret uses a servo motor to drive the tool head, enabling bidirectional rapid tool selection. The machine tool controller directly controls the servo motor for tool changing, significantly shortening the tool change cycle time. This design makes the powered turret suitable for lathes performing both forward and reverse machining, easily handling even heavy cutting operations. Currently, most powered turrets on the market use two motors: a tool position rotary motor that controls the rotation of the tool on the tool head, and a tool drive motor that controls the rotation of the cutting tool. While hydraulic locking gear discs are used, their disadvantage is that using two motors means occasional electrical interference requires one or two additional hydraulic lines, which can lead to oil leaks and other defects over time.

[0004] Therefore, a single servo motor powered turret is proposed to address the aforementioned technical issues. Summary of the Invention

Referring to Figures 1, 2 and 7, a cylinder box 11 is connected to one side of the powered turret body 1, and a tool disc 2 is connected to one end of the powered turret body 1. A connecting tool holder 21 is provided on the tool disc 2. A drive connecting turntable 22 and a transmission connecting turntable 23 are arranged sequentially on the side of the tool disc 2 near the powered turret body 1. A cutting tool 3 is connected inside the connecting tool holder 21.

[0030] The tool 3 is internally connected to a tool head 31, and a tool head drive block 311 is provided at one end of the tool head 31.

The tool 3 is installed and connected to the connecting tool holder 21 of the cutter head 2, and the tool to be used can be switched by rotating the cutter head 2 during use. The driving operation of the tool head 31 of the power turret body 1 and the switching action of the tool 3 on the cutter head 2 are both driven by the drive motor 5, and the switching function between the driving operation of the tool head 31 and the switching of the tool 3 on the cutter head 2 is controlled by the drive conversion cylinder 61. The rotation of the tool head 31 is driven by the tool head drive block 311, and the tool head drive block 311 is driven by the drive motor 5 through the drive assembly 6 to perform machining work.

[0031] Referring to Figures 3 and 4, a telescopic rotary connecting shaft 611 is connected to the drive conversion cylinder 61 via a bearing, and a coupling 65 is connected to one end of the telescopic rotary connecting shaft 611 near the drive connecting block 62. A switching bevel gear 64 is slidably sleeved on the outer side of the telescopic rotary connecting shaft 611. The drive conversion cylinder 61 drives the telescopic rotary connecting shaft 611 to extend and retract, and during the extension and retraction of the telescopic rotary connecting shaft 611, the position of the switching bevel gear 64 connected to it remains unchanged, while the telescopic rotary connecting shaft 611 drives the switching bevel gear 64 to rotate during rotation.

[0032] Referring to Figures 4 and 6, a transmission gear 63 is sleeved between the drive connecting block 62 and the coupling 65. A drive gear 51 is connected to the output shaft of the drive motor 5, and the transmission gear 63 and the drive gear 51 are connected within the motor connecting block 4 via a transmission gear belt. The drive motor 5 drives the drive gear 51 to rotate, and during the rotation of the drive gear 51, the transmission gear 63 is driven to rotate within the motor connecting block 4 via a transmission gear belt. During the rotation of the transmission gear 63, the drive connecting block 62 and the telescopic rotary connecting shaft 611 connected to it are driven to rotate via the coupling 65.

[0033] Referring to Figures 4 and 5, a drive gear collar 612 is provided at one end of the telescopic rotary connecting shaft 611 near the cutter 3. A cutter head drive gear 312 that engages with the drive gear collar 612 is connected to one end of the cutter head drive block 311 near the drive gear collar 612. During the telescopic rotary connecting shaft 611 telescopically extends or retracts, it drives the drive gear collar 612 to move closer to or further away from the cutter head drive block 311 to assist in the function switching of the power turret body 1. When driving the cutter head 31 of the cutter 3, the telescopic rotary connecting shaft 611 drives the drive gear collar 612 connected to it to rotate. During the rotation of the drive gear collar 612, it drives the cutter head drive gear 312, the cutter head drive block 311 connected to it, and the cutter head 31 to rotate. When switching to the cutter head 3 of the cutter disc 2, the telescopic rotary connecting shaft 611 and the drive gear collar 612 connected to it move away from the cutter head drive gear 312. At the same time as the movement, the drive gear collar 612 is disconnected from the cutter head drive gear 312.

[0034] Referring to Figures 3 and 8, a switching transmission assembly 12 is provided between the transmission connecting turntable 23 and the drive conversion cylinder 61, and one end of the switching transmission assembly 12 is provided with a drive bevel gear 121 that meshes with the switching bevel gear 64; during the rotation of the telescopic rotary connecting shaft 611, the drive bevel gear 121 connected to the switching transmission assembly 12 is driven to rotate by the switching bevel gear 64.

[0035] Referring to Figures 7 and 10, a drive gear ring 221 is provided on the side of the drive connecting turntable 22 near the transmission connecting turntable 23, and a transmission gear ring 232 that meshes with the drive gear ring 221 is provided on the side of the transmission connecting turntable 23 near the drive connecting turntable 22. During the rotation of the transmission connecting turntable 23, the drive gear ring 221 and the drive connecting turntable 22 connected thereto are driven to rotate through the transmission gear ring 232, thereby driving the cutter head 2 to rotate through the drive connecting turntable 22. During the rotation of the cutter head 2, the connecting cutter holder 21 and the cutter 3 and cutter head 31 connected thereto are rotated and switched.

[0036] Referring to Figures 8 and 9, a drive gear ring 231 is provided on the inner side of the transmission connecting turntable 23, and a switching gear 122 that meshes with the drive gear ring 231 is sleeved on the outer side of the switching transmission assembly 12; during the rotation of the switching transmission assembly 12, the drive gear ring 231 and the transmission connecting turntable 23 connected thereto are driven to rotate through the switching gear 122.

[0037] Referring to Figures 7 and 10, a switching lifting cylinder 111 is provided inside the cylinder housing 11, and a lifting telescopic rod 113 symmetrical to the switching lifting cylinder 111 is provided at the bottom of one end of the drive connecting turntable 22. When switching to the tool 3 on the cutter head 2, the switching lifting cylinder 111 in the cylinder housing 11 drives the drive connecting turntable 22 to lift and lower. During the lifting and lowering process, the drive connecting turntable 22 drives the lifting telescopic rod 113 to extend and retract, and the lifting telescopic rod 113 makes the lifting and lowering of the drive connecting turntable 22 more stable.

[0038] Referring to Figure 10, a lifting transmission connecting ring 222 is sleeved on the outer side of the drive connecting turntable 22 via a bearing. Lifting connecting blocks 112 are connected between the lifting transmission connecting ring 222 and the output shaft of the switching lifting cylinder 111, and between the lifting transmission connecting ring 222 and the lifting telescopic rod 113. The switching lifting cylinder 111 drives the lifting transmission connecting ring 222 and the drive connecting turntable 22 connected to it to perform lifting and lowering operations through the lifting connecting blocks 112. The position of the lifting transmission connecting ring 222 will not be affected during the rotation of the drive connecting turntable 22.

[0039] The working process of this application is as follows: First, the tool 3 is installed and connected to the connecting tool holder 21 of the tool disc 2. When performing milling, drilling, and other machining operations, the drive motor 5 drives the drive gear 51 to rotate. During the rotation of the drive gear 51, the drive gear 51 drives the transmission gear 63 to rotate through the transmission gear belt in the motor connecting block 4. During the rotation of the transmission gear 63, the drive connecting block 62 and the telescopic rotary connecting shaft 611 connected to it are driven to rotate through the coupling 65. The telescopic rotary connecting shaft 611 drives the drive gear collar 612 connected to it to rotate. During the rotation of the drive gear collar 612, the tool head drive gear 312, the tool head drive block 311 connected to it, and the tool head 31 are driven to rotate. The drive motor can also drive the tool disc to rotate.

[0040] When switching the tool 3 on the cutter head 2, the drive conversion cylinder 61 drives the telescopic rotary connecting shaft 611 to extend and retract. During the extension and retraction, the telescopic rotary connecting shaft 611 drives the drive gear collar 612 to move closer to or away from the tool head drive block 311 to assist in the function switching of the power turret body 1. When switching to the tool 3 on the cutter head 2, the telescopic rotary connecting shaft 611 and the drive gear collar 612 connected to it move away from the tool head drive gear 312. At the same time, the drive gear collar 612 is disconnected from the tool head drive gear 312. Meanwhile, the switching lifting cylinder 111 drives the lifting transmission connecting ring 222 and the drive connecting turntable 22 connected to it to lift and lower through the lifting connecting block 112. The drive connecting turntable 22 does not affect the position of the lifting transmission connecting ring 222 during the rotation. During the lifting and lowering process, the drive connecting turntable 22 drives the lifting telescopic rod 113 to extend and lower, and the lifting telescopic rod 113 makes the lifting and lowering of the drive connecting turntable 22 more stable.

[0041] Then, the drive motor 5 drives the telescopic rotary connecting shaft 611 to rotate. During the rotation of the telescopic rotary connecting shaft 611, the switching bevel gear 64 drives the drive bevel gear 121 connected to the switching transmission assembly 12 to rotate. During the rotation of the switching transmission assembly 12, the drive gear ring 231 and the transmission connecting turntable 23 connected to it are driven to rotate through the switching gear 122. During the rotation of the transmission connecting turntable 23, the drive gear ring 221 and the drive connecting turntable 22 connected to it are driven to rotate through the transmission gear ring 232. Thus, the drive connecting turntable 22 drives the cutter head 2 to rotate. During the rotation of the cutter head 2, the connecting cutter holder 21 and the cutter 3 and cutter head 31 connected to it are rotated and switched.

[0042] Compared with existing technologies, this single servo motor powered turret has a compact structure and can complete the function switching work through a single motor, avoiding electrical interference of signals. The switching function between the driving work of the tool head 31 and the switching of the tool 3 on the tool disc 2 is controlled by the drive switching cylinder 61. The function switching between the driving work of the tool head 31 and the switching of the tool 3 on the tool disc 2 of this single servo motor powered turret is fast and convenient. Moreover, when switching, the single servo motor powered turret uses vertical gear meshing, which makes the gear meshing position less prone to misalignment than the meshing of bevel gears, making it safer.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
