Technical Field
[0001] This utility model relates to the field of turret technology, specifically to a quick-change turret. Background Technology
[0002] As the manufacturing industry continues to develop towards higher precision, higher efficiency, and automation, CNC machine tools, as key processing equipment, play an irreplaceable role. The CNC turret, as one of the core functional components of a CNC machine tool, directly affects the machine tool's processing capacity, processing accuracy, and production efficiency.
[0003] For example, Chinese Patent No. CN218252949U discloses a turret that belongs to the field of turrets. It includes: a turret shell and a cutter head, a motor, and a motor located inside the turret shell; a motor shaft, with one end of the motor extending out; wherein, the top end of the motor shaft is fixedly connected to the cutter head and drives the cutter head to rotate. The motor located inside the turret shell and extending out to the cutter head is fixedly connected to the cutter head to drive the cutter head to rotate. The integrated design allows direct control of the cutter head's rotation, improving the accuracy of controlling the cutter head's rotation angle.
[0004] In practical applications of tool turrets, the installation stability of the cutting tool is a major concern. Currently, traditional tool turrets lack effective pressure monitoring methods after tool installation. Since the installation pressure directly affects the tool's stability during subsequent machining, insufficient installation pressure can cause the tool to loosen due to cutting forces, vibrations, and other factors during machining. This loosening not only leads to a significant decrease in machining accuracy, causing dimensional deviations and poor surface quality in the machined parts, failing to meet the requirements of high-precision machining, but may also lead to more serious consequences. For example, if the tool continues to participate in machining in a loose state, it will bear excessive stress due to uneven force distribution, resulting in tool damage. Once the tool is damaged, not only is it necessary to stop the machine to replace the tool, causing production interruption and reducing production efficiency, but it may also damage other components of the machine tool, increasing maintenance costs. Therefore, those skilled in the art provide a quick-change tool turret to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figures 1-5As shown, this utility model provides a technical solution: a quick-change turret, including a tool holder body 1 and a turret body 2. The turret body 2 is disposed on the outer side wall of the tool holder body 1. The tool holder body 1 is provided with a drive mechanism 3 that drives the turret body 2 to rotate. A lathe tool 5 is bolted to the tool mounting position of the turret body 2. An alarm mechanism 4 for detecting the mounting pressure of the lathe tool 5 is provided inside the turret body 2.
[0023] It should be noted that the turret body 2 is equipped with an alarm mechanism 4 to detect the installation pressure of the cutting tool 5. When the installation pressure of the cutting tool 5 is abnormal, the alarm mechanism 4 can issue an alarm in time to remind the operator and avoid the cutting tool 5 from becoming loose, damaged or affecting the machining quality due to improper installation pressure. This ensures the safety and stability of the machining process, reduces the risk of machining accidents caused by tool problems, and improves the overall machining quality and service life of the equipment.
[0024] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, the drive mechanism 3 includes a drive motor 31 fixedly connected to the outer wall of the tool holder body 1. The output end of the drive motor 31 is fixedly connected to a first synchronous pulley 32. A main shaft 36 is rotatably sleeved inside the tool holder body 1. One end of the main shaft 36 is fixedly connected to a second synchronous pulley 33, and the second synchronous pulley 33 is located on the outer wall of the tool holder body 1. A synchronous belt 34 is sleeved on the outer wall of the first synchronous pulley 32 and the second synchronous pulley 33.
[0025] It should be noted that the drive motor 31, which is fixedly connected to the outer wall of the tool holder body 1, is used as the power source. Its position is reasonable, which facilitates installation and maintenance. At the same time, it can reduce the occupation of the internal space of the tool holder body 1, making the overall structure more compact. The output end of the drive motor 31 is connected to the first synchronous pulley 32, and one end of the spindle 36 is connected to the second synchronous pulley 33. Power is transmitted through the synchronous belt 34, which ensures smooth operation and can guarantee the stability of the tool turret body 2 during rotation, reduce vibration and noise, and thus improve machining accuracy and product quality.
[0026] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3As shown, the inner wall of the tool holder body 1 is rotatably sleeved with a first connecting shaft 35 on one side of the main shaft 36. Two inner bearings 351 are symmetrically fixedly connected to the inner wall of the tool holder body 1. The two inner bearings 351 are located at both ends of the first connecting shaft 35. The first connecting shaft 35 is rotatably sleeved with the tool holder body 1 through the inner bearings 351. A first gear 352 is fixedly connected to the outer wall of the first connecting shaft 35. A second gear 37 is fixedly connected to the outer wall of the main shaft 36. The first gear 352 and the second gear 37 mesh and drive each other. A first gear disk 38 is fixedly connected to the outer wall of the main shaft 36. A second gear disk 39 is fixedly connected to the side of the turret body 2 near the tool holder body 1. The interior of the turret body 2 is bolted to the end of the main shaft 36 away from the tool holder body 1. The first gear disk 38 and the second gear disk 39 mesh and drive each other.
[0027] It should be noted that the first connecting shaft 35 is rotatably sleeved on the inner wall of the tool holder body 1 through two inner bearings 351. This installation method ensures the smoothness and flexibility of the rotation of the first connecting shaft 35, reduces frictional resistance during rotation, reduces energy loss, improves transmission efficiency, and also extends the service life of the components. The first gear 352 meshes with the second gear 37 to realize the power transmission between the first connecting shaft 35 and the spindle 36. This gear meshing transmission method has the advantages of accurate and reliable transmission, which can ensure that the spindle 36 rotates stably according to the preset transmission ratio, providing a basis for the precise rotation of the subsequent tool turret body 2. The spindle 36 meshes with the second gear 39 on the tool turret body 2 through the first gear 38 to drive the tool turret body 2 to rotate. This gear meshing transmission method further ensures the accuracy and stability of the transmission, enabling the tool turret body 2 to accurately switch tool positions to meet the needs of different processing procedures.
[0028] As one implementation method in this embodiment, please refer to Figure 1 and Figure 4 As shown, the turret body 2 has eight tool mounting positions. The outer wall of the turret body 2 has a positioning hole 21 at each tool mounting position. The outer wall of the turret body 2 has guide holes 22 on both sides of the positioning hole 21. The outer wall of the turret body 2 has four mounting holes 23 on both sides of the positioning hole 21 and the guide holes 22. The cutting tool 5 is limited by bolts cooperating with the mounting holes 23.
[0029] It should be noted that each tool mounting position has a positioning hole 21, which provides a precise positioning reference for the installation of the cutting tool 5. This ensures that the cutting tool 5 can quickly and accurately reach the predetermined position during installation, improving the installation accuracy and efficiency, and reducing machining errors caused by inaccurate positioning. The guide hole 22 further optimizes the installation process of the cutting tool 5, playing a guiding role during installation, allowing the cutting tool 5 to enter the mounting position more smoothly and steadily, reducing the installation difficulty, and also avoiding damage to the cutting tool 5 or the turret body 2 due to improper installation. The reasonable distribution of the four mounting holes 23, together with the bolts, achieves reliable limiting of the cutting tool 5, ensuring the stability of the cutting tool 5 during machining, effectively preventing the cutting tool 5 from displacing due to vibration or force, thereby ensuring machining quality.
[0030] As one implementation method in this embodiment, please refer to Figure 4 and Figure 5 As shown, the alarm mechanism 4 includes pressure sensors 41 fixedly connected inside each positioning hole 21. Two guide rods 43 are symmetrically fixedly connected to the side of the cutting tool 5 near the turret body 2, and the two guide rods 43 are slidably connected to the guide hole 22. A pressure plate 42 is fixedly connected to the center of the side of the cutting tool 5 near the turret body 2. A PLC control panel 44 is fixedly connected to the top of the tool holder body 1. Eight warning lights 45 are provided on the top of the tool holder body 1, and the eight warning lights 45 correspond to the eight pressure sensors 41. Two mounting brackets 46 are symmetrically fixedly connected to the top of the tool holder body 1. An alarm 47 is fixedly connected inside the two mounting brackets 46. A wireless signal transmission module is installed inside the pressure sensor 41. A wireless signal control module is installed inside the PLC control panel 44. Wireless signal receiving modules are installed inside the warning lights 45 and the alarm 47.
[0031] It should be noted that a pressure sensor 41 is installed in each positioning hole 21 to accurately detect the pressure during the installation of the cutting tool 5. If the pressure is abnormal, it can be detected and reported in a timely manner, providing basic data support for ensuring machining safety and quality. The guide rod 43 on the cutting tool 5 is slidably connected to the guide hole 22, ensuring the stability of the cutting tool 5 installation. At the same time, the pressure plate 42 allows the cutting tool 5 to better contact the pressure sensor 41 during installation, ensuring the accuracy of pressure detection. The eight warning lights 45 on the tool holder body 1 correspond one-to-one with the eight pressure sensors 41. When a pressure sensor 41 detects pressure... When the pressure is abnormal, the corresponding warning light 45 will light up, visually indicating the location of the problematic tool, making it easy for operators to quickly locate and handle the problem. The alarm 47 is set to emit an alarm sound when the pressure is abnormal, which, together with the warning light 45, alerts the operator from both visual and auditory perspectives, enhancing the warning effect. Through the wireless signal transmission module, wireless signal control module, and wireless signal receiving module, wireless communication between the pressure sensor 41, PLC control panel 44, warning light 45, and alarm 47 is realized, eliminating the need for complex wiring connections, simplifying the equipment structure, and improving the convenience of installation and maintenance.
[0032] Working principle: When it is necessary to install the cutting tool 5 on the turret body 2, the cutting tool 5 is limited by bolts and four mounting holes 23 corresponding to the tool mounting positions on the turret body 2. During the installation process, two guide rods 43 symmetrically fixedly connected to the side of the cutting tool 5 near the turret body 2 are slidably connected to the guide holes 22 opened on both sides of the corresponding positioning holes 21 on the outer wall of the turret body 2, which play a guiding role. At the same time, the pressure plate 42 fixedly connected at the center of the side of the cutting tool 5 near the turret body 2 will squeeze the pressure sensor 41 fixedly connected inside each positioning hole 21.
[0033] If the pressure exerted by the cutting tool 5 on the turret body 2 is insufficient, the wireless signal transmission module inside the pressure sensor 41 will promptly transmit a signal to the PLC control panel 44 fixedly connected to the top of the tool holder body 1. Upon receiving the signal, the wireless signal control module inside the PLC control panel 44 will activate the alarm 47 inside the two mounting brackets 46 symmetrically fixed to the top of the tool holder body 1. Simultaneously, since the eight warning lights 45 correspond to the eight pressure sensors 41, the PLC control panel 44 will control the warning light 45 corresponding to the insufficient pressure to issue a warning. Through this series of processes, operators can quickly identify which cutting tool 5 has insufficient installation pressure and address it promptly, preventing damage to the cutting tool 5 due to insufficient pressure during processing. This ensures processing safety and stability, improves production efficiency, and enhances product quality.
[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
