Description

Technical Field

[0001] This utility model relates to the technical field of tool disc locking connection equipment, specifically a rotary locking connection mechanism for quick-change tool discs. Background Technology

[0002] In the field of modern industrial processing, with the continuous increase in product diversification and high-precision processing demands, extremely stringent requirements have been placed on the flexibility, efficiency and stability of processing equipment. Among them, the quick-change tool head, as a key component of processing equipment, directly affects the overall efficiency of the equipment.

[0003] Most existing quick-change tool turrets use fixed-position tools, with the tools located off-center. During rotation and lifting, these misaligned tools are prone to breakage or displacement, and also increase the need for manual alignment and adjustment. Utility Model Content

[0004] The purpose of this utility model is to provide a rotation locking connection mechanism for a quick-change tool disc, which addresses the problem that most existing quick-change tool discs use fixed positions for the tools, and the tools are located in non-central positions on the quick-change tool disc. During rotation and lifting, the misaligned tools are prone to breakage or displacement, and the manual alignment and adjustment steps are also increased.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary locking connection mechanism for a quick-change cutter head, comprising: a cutter head connecting telescopic component and a connecting cover, a cutter head support ring fixedly connected to the bottom end of the connecting cover, a quick-change cutter head mounted on the top end inside the cutter head support ring, a cutter moving groove formed on the bottom surface of the quick-change cutter head, an anti-detachment edge ring fixedly connected to the bottom end of the inner side of the cutter moving groove, a cutter moving seat slidably connected inside the cutter moving groove, a cutter mounted on the bottom end of the cutter moving seat, a gear ring fixedly connected to the outer side of the top end of the quick-change cutter head, a drive motor fixedly connected to the bottom surface of one end inside the connecting cover, and a drive gear fixedly sleeved on the end of the output shaft of the drive motor.

[0006] As a further embodiment of this utility model: the connecting cover is fixed to the bottom output end face of the cutter head connecting telescopic component, the cutter head support ring is configured as a ring structure with a central through-hole, and the quick-change cutter head is embedded inside the cutter head support ring and can rotate flexibly.

[0007] As a further embodiment of this utility model: the tool moving groove is configured to consist of several sets of moving groove structures arranged in a ring, and several sets of tool moving seats and tools are slidably connected inside. The anti-detachment edge ring supports the bottom surface of several sets of tool moving seats to prevent them from detaching from the tool moving groove.

[0008] As a further improvement of this utility model: a square hydraulic telescopic column is embedded inside the bottom surface of the tool moving seat, and a square insertion positioning groove structure that matches the specifications of the end of the square hydraulic telescopic column is opened in the center of the quick-change tool disc, so that the tool moving seat pushed to the center of the quick-change tool disc is accurately positioned.

[0009] As a further embodiment of this utility model: a magnetic block is fixedly embedded on one side of the tool moving seat, and a through-rod slot is symmetrically opened at the end of the tool moving groove. A hydraulic telescopic push rod is installed at one end inside the connecting cover. A magnetic block is fixedly connected to the end face of the hydraulic telescopic push rod. The magnetic block and the magnetic block are magnetically attracted to each other, so as to automatically attract and push the tool moving seat to the center position of the quick-change tool disc.

[0010] As a further improvement of this utility model, the gear ring fixed to the top surface of the quick-change tool disc meshes with the drive gear of the drive motor, so as to drive the gear ring and the quick-change tool disc to rotate precisely through the drive gear.

[0011] As a further embodiment of this utility model: a hydraulic lifting column is fixedly connected to the center of the top surface inside the connecting cover, and a positioning tooth pressure plate is fixedly connected to the end face of the hydraulic lifting column.

[0012] As a further improvement of this utility model: a positioning toothed disc is fixedly connected to the top surface of the quick-change tool disc, and the positioning toothed disc and the positioning toothed pressure plate are arranged opposite to each other and their specifications and positions are compatible, so as to conveniently fix and lock the angle of the quick-change tool disc.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, multiple sets of circularly arranged tool moving slots accommodate various types of tools. With the automatic adsorption and docking of magnetic blocks and the pushing of hydraulic telescopic push rods, the target tool moving seat can automatically slide along the slot. At the same time, the precise cooperation between the square hydraulic telescopic column and the square insert positioning slot can restrict the center position of the tool moving seat from both radial and circumferential directions, which not only avoids the offset caused by processing vibration, but also eliminates the step of manual alignment and adjustment. The tool changing efficiency and positioning accuracy are significantly better than similar equipment. This invention employs a drive gear and gear ring meshing transmission. Leveraging the advantages of precise gear ratio and rapid response, it can accurately control the rotation angle and speed of the quick-change tool disc. During the locking phase, a hydraulic lifting column drives the positioning tooth pressure plate and positioning tooth groove plate to mesh, using the strong holding force of the tooth meshing to prevent the tool disc from rotating during processing. Unlocking can be quickly completed simply by retracting the hydraulic lifting column. This achieves highly efficient coordination of precise rotation, secure locking, and flexible unlocking, and its processing stability and angle adjustment convenience far exceed those of similar equipment.

In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0018] Reference Figures 1 to 6 In this embodiment of the utility model, a rotary locking connection mechanism for a quick-change cutter disc includes: a cutter disc connecting telescopic member 1 and a connecting cover 2. A cutter disc support ring 3 is fixedly connected to the bottom end of the connecting cover 2. A quick-change cutter disc 4 is mounted on the top inside the cutter disc support ring 3. A cutter moving groove 5 is opened on the bottom surface of the quick-change cutter disc 4. An anti-detachment edge ring 6 is fixedly connected to the bottom inside the cutter moving groove 5. A cutter moving seat 7 is slidably connected inside the cutter moving groove 5. A cutter 8 is installed at the bottom end of the cutter moving seat 7. A gear ring 15 is fixedly connected to the outer side of the top of the quick-change cutter disc 4. A drive motor 16 is fixedly connected to the bottom surface of one end inside the connecting cover 2. A drive gear 17 is fixedly sleeved at the end of the output shaft of the drive motor 16.

[0019] Reference Figure 1 The connecting cover 2 is fixed to the bottom output end face of the cutter head connecting telescopic component 1. The cutter head support ring 3 is set as a ring structure with the center through. The quick-change cutter head 4 is embedded in the cutter head support ring 3 and can rotate flexibly.

[0020] The above-mentioned solution ensures that the connecting cover 2 and the cutter head connecting telescopic component 1 form a stable overall structure. The cutter head connecting telescopic component 1 can drive the entire connecting cover 2 and the components below to extend and retract to adapt to different working height requirements. The central through-hole design of the cutter head support ring 3 provides installation space for the quick-change cutter head 4 and also provides good support for it. The quick-change cutter head 4 is embedded in the cutter head support ring 3 and can rotate flexibly, which allows the cutter head to flexibly adjust its angle according to processing requirements, making it easy to switch between different tools 8 for operation, thus improving the flexibility and adaptability of the equipment.

[0021] Reference Figure 4 and Figure 5 The tool moving groove 5 is configured to consist of several sets of moving groove structures arranged in a ring, and several sets of tool moving seats 7 and tools 8 are slidably connected inside. The anti-detachment edge ring 6 supports the bottom surface of several sets of tool moving seats 7 to prevent them from detaching from the tool moving groove 5.

[0022] The above scheme adopts a multi-group ring arrangement design for the tool moving groove 5, which can accommodate multiple sets of tool moving seats 7 and tools 8. This means that multiple different types of tools 8 can be installed at the same time to meet the needs of complex machining tasks. There is no need to frequently disassemble and replace tools, saving tool changing time. The anti-detachment ring 6 provides reliable bottom support for the tool moving seat 7. During the sliding process of the tool moving seat 7 along the tool moving groove 5, it effectively prevents it from falling out of the groove due to sliding inertia or external force, ensuring the stability and safety of the tool moving process and ensuring the smooth progress of the machining process.

[0023] Reference Figure 4 and Figure 5 The tool moving seat 7 has a square hydraulic telescopic column 9 embedded in its bottom surface. The quick-change tool disc 4 has a square insertion positioning groove 10 structure in the center that matches the specifications of the end of the square hydraulic telescopic column 9, so that the tool moving seat 7 pushed to the center of the quick-change tool disc 4 can be accurately positioned.

[0024] The above-mentioned design, which combines the square hydraulic telescopic column 9 with the square insertion column positioning groove 10, has unique advantages. Compared with the circular structure, the square structure can better restrict the degree of rotational freedom. When the tool moving seat 7 is pushed to the center of the quick-change tool disc 4, the square hydraulic telescopic column 9 extends and inserts into the square insertion column positioning groove 10, which can achieve precise positioning of the tool moving seat 7 in the radial and circumferential directions. This avoids the tool moving seat 7 from shifting due to factors such as vibration during the machining process, thus ensuring the machining accuracy of the tool 8. At the same time, the hydraulic drive makes the telescopic action smooth and reliable, and the positioning process is highly automated, improving the positioning efficiency and accuracy.

[0025] Reference Figure 4 and Figure 6 A magnetic block 11 is fixedly embedded on one side of the tool moving seat 7. A through-rod slot 12 is symmetrically opened at the end of the tool moving groove 5. A hydraulic telescopic push rod 13 is installed at one end inside the connecting cover 2. A magnetic block 14 is fixedly connected to the end face of the hydraulic telescopic push rod 13. The magnetic block 14 at the end of the hydraulic telescopic push rod 13 is magnetically attracted to the magnetic block 11, so as to automatically attract and push the tool moving seat 7 to the center position of the quick-change tool disc 4.

[0026] The above scheme utilizes the magnetic attraction design of magnetic block 11 and magnetic block 2 14 to achieve flexible connection and automatic docking between the hydraulic telescopic push rod 13 and the tool moving seat 7. When the hydraulic telescopic push rod 13 extends, magnetic block 2 14 can automatically attract magnetic block 11 through magnetic force, allowing the tool moving seat 7 to slide along the tool moving groove 5 without precise alignment. This simplifies the control difficulty of the drive mechanism. The through-rod groove 12 provides a channel for the end of the hydraulic telescopic push rod 13 to pass through the tool moving groove 5, ensuring that it can smoothly contact the tool moving seat 7 and push it to move. This automatic attraction and pushing method makes the movement of the tool moving seat 7 more stable and efficient, with a high degree of automation, reducing manual intervention and improving the working efficiency of the equipment.

[0027] Reference Figure 2 and Figure 3 The gear ring 15 fixed to the top surface of the quick-change tool disc 4 meshes with the drive gear 17 of the drive motor 16, so that the gear ring 15 and the quick-change tool disc 4 can be driven to rotate precisely through the drive gear 17.

[0028] The above scheme features a precise transmission ratio, high transmission efficiency, and compact structure in the meshing transmission between the gear ring 15 and the drive gear 17. The drive motor 16 provides power, and through the meshing of the drive gear 17 and the gear ring 15, the rotation angle and speed of the quick-change tool disc 4 can be precisely controlled to meet the precise requirements of different processing steps for the rotation position of the tool disc. This transmission structure makes the rotation action of the quick-change tool disc 4 respond quickly and position accurately, which helps to improve processing accuracy and product quality. At the same time, the gear transmission has high reliability and long service life, reducing the maintenance cost of the equipment.

[0029] Reference Figure 2 and Figure 6 A hydraulic lifting column 19 is fixedly connected to the center of the top surface inside the connecting cover 2. A positioning tooth pressure plate 20 is fixedly connected to the end face of the hydraulic lifting column 19. A positioning tooth groove plate 18 is fixedly connected to the top surface of the quick-change cutter head 4. The positioning tooth groove plate 18 and the positioning tooth pressure plate 20 are arranged opposite to each other and their specifications and positions are compatible, so as to facilitate the fixing and locking of the angle of the quick-change cutter head 4.

[0030] Using the above scheme: the hydraulic lifting column 19 can drive the positioning tooth pressure plate 20 to achieve precise lifting and lowering. When the quick-change tool disc 4 rotates to the required angle, the hydraulic lifting column 19 extends, so that the positioning tooth pressure plate 20 and the positioning tooth groove plate 18 mesh with each other. The meshing action of the tooth structure can firmly lock the quick-change tool disc 4 at the current angle, preventing it from rotating during processing and ensuring the stability and accuracy of processing. When it is necessary to adjust the angle of the quick-change tool disc 4, the hydraulic lifting column 19 retracts, the positioning tooth pressure plate 20 separates from the positioning tooth groove plate 18, and the lock is released. The operation is convenient and efficient. Compared with other locking methods, this tooth-type locking method has the advantages of firm locking, accurate positioning, and fast operation, which greatly improves the working efficiency and reliability of the equipment.

[0031] The working principle of this utility model is as follows: the overall structure is based on the cutter head connecting telescopic component 1, and the connecting cover 2 fixed to the bottom output end face forms the main frame of the mechanism. The cutter head support ring 3 at the bottom of the connecting cover 2 provides stable installation and rotation support for the quick-change cutter head 4, so that the quick-change cutter head 4 can rotate flexibly in the cutter head support ring 3. At the same time, the cutter head connecting telescopic component 1 can drive the overall structure to extend and retract to adapt to different working heights. In terms of tool switching and positioning, the tool moving groove 5 on the bottom surface of the quick-change tool disc 4 adopts a multi-group ring arrangement design, which can accommodate multiple sets of tool moving seats 7 and tools 8 to meet diverse processing needs. When a specific tool 8 needs to be moved to the working position, the hydraulic telescopic push rod 13 inside the connecting cover 2 extends out, and the magnetic block 14 at its end magnetically attracts the magnetic block 11 on one side of the target tool moving seat 7 through the rod groove 12, thereby pushing the tool moving seat 7 to slide along the tool moving groove 5 towards the center of the quick-change tool disc 4. During this process, the anti-detachment edge ring 6 effectively supports the tool moving seat 7 to prevent it from detaching. When the tool moving seat 7 reaches the center position, the square hydraulic telescopic column 9 inside its bottom surface extends out and accurately inserts into the square insertion column positioning groove 10 in the center of the quick-change tool disc 4, realizing the stable positioning of the tool moving seat 7 in the radial and circumferential directions, and ensuring the processing accuracy of the tool 8. In the rotation and locking control of the quick-change tool disc 4, when the drive motor 16 inside the connecting cover 2 is working, the drive gear 17 at the end of its output shaft meshes with the gear ring 15 on the outer side of the top of the quick-change tool disc 4, driving the quick-change tool disc 4 to rotate precisely to the required angle. After the angle is determined, the hydraulic lifting column 19 at the center of the top surface inside the connecting cover 2 extends, so that the positioning tooth pressure plate 20 at the end meshes with the positioning tooth groove plate 18 on the top surface of the quick-change tool disc 4. The quick-change tool disc 4 is firmly locked by the meshing action of the tooth structure to prevent rotation during processing. When the angle needs to be adjusted again, the hydraulic lifting column 19 retracts, the positioning tooth pressure plate 20 separates from the positioning tooth groove plate 18, the lock is released, and the drive motor 16 can drive the quick-change tool disc 4 to rotate again.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
