Description

Technical Field

[0001] This utility model relates to the technical field of end connection structure of actuators, and in particular to an anti-loosening detachable structure, and a floating grinding head with an anti-loosening detachable structure. Background Technology

[0002] In the field of industrial automation, especially in applications involving high-precision machining or surface treatment, actuators, such as floating grinding heads, are widely used. These actuators are typically driven by a drive disc, which moves the actuating elements, such as grinding heads and brushes, to perform precise movements for grinding and deburring. In related technologies, the internal structure of the actuators is quite intricate. The drive disc, which provides the direct power output to the actuator, is mostly non-removable. Generally, a transmission disc is fixedly connected to the drive disc, and the actuating element is connected to the transmission disc.

[0003] However, the existing application has the following problems:

[0004] 1. Connection displacement: Under prolonged use or vibration, the transmission disc is prone to displacement relative to the drive disc. This directly affects the motion accuracy and stability of the actuator, and consequently the quality of the final product.

[0005] 2. Disassembly error: The actuator and the transmission plate are generally connected by a connecting flange. However, when disassembling the connecting flange, there is a possibility of accidental disassembly or damage to the transmission plate. Since the internal structure of the actuator is relatively precise, frequent disassembly and assembly of the transmission plate will further reduce the motion accuracy of the actuator's drive plate output.

[0006] 3. Insufficient maintainability: In order to improve the stability of the actuator, some applications completely fix the transmission disk and the drive disk. Although this can reduce the risk of loosening and displacement, it also means that replacing and fine-tuning the transmission disk becomes very inconvenient, reducing production efficiency and flexibility.

[0007] To address the aforementioned issues, there is an urgent need in the market for a non-loosening structure that can ensure connection stability while also enabling a quick and easy assembly / disassembly process for routine maintenance and tooling replacement. Utility Model Content

[0008] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an anti-loosening and detachable structure, which provides a more flexible operating experience without sacrificing connection strength, and minimizes the impact on the actuator itself, thereby ensuring the long-term stable operation of the entire system.

[0009] This utility model also proposes a floating grinding head with the above-mentioned anti-loosening and detachable structure.

[0010] The anti-loosening and detachable structure according to this utility model includes:

[0011] An actuator is provided with a drive disk, and the outer peripheral wall of the drive disk is provided with a plug-in hole;

[0012] A transmission disc is disposed on the drive disc and moves together with the drive disc;

[0013] An anti-loosening component is installed on the inner side of the transmission disk. The anti-loosening component includes a compression spring and a plug block. One side of the compression spring abuts against the inner side of the transmission disk, and the other end is connected to and drives the plug block to be inserted into the plug hole.

[0014] The drive disk and the transmission disk are non-magnetic components, while the plug-in block is a magnetic component. The plug-in block moves away from the center of the drive disk and disengages from the plug-in hole via a magnetic attraction component located on the outside of the transmission disk, thereby removing the transmission disk.

[0015] According to the anti-loosening detachable structure described in this utility model, it has at least the following beneficial effects: The anti-loosening assembly with a compression spring and a plug-in block between the transmission disc and the drive disc not only ensures the stability and accuracy of the connection between the transmission disc and the drive disc, but also reduces the risk of accidentally disassembling the transmission disc when removing the connecting flange to replace the actuator. Furthermore, when connected to the actuator via the connecting flange and in normal working condition, the drive disc, transmission disc, and connecting flange are connected sequentially and move together. When disassembly is required, the connecting flange can be disassembled separately. Because the transmission disc acts as a buffer, the risk of damage to the drive disc due to disassembly is reduced, simplifying the maintenance process, ensuring the long-term stable operation of the drive disc, and improving production efficiency and flexibility. Alternatively, the plug-in block can be attracted by an external magnetic attractor, causing it to detach from the plug-in hole, thereby achieving easy disassembly of the connecting flange and the transmission disc. This allows for necessary fine-tuning of the connection between the transmission disc and the drive disc, improving equipment maintainability and production efficiency, and meeting the needs of high-precision machining or surface treatment applications in the field of industrial automation.

[0016] According to some embodiments of the present invention, the transmission disc and the drive disc are fixedly connected by pins or screws.

[0017] According to some embodiments of the present invention, an anti-loosening detachable structure is provided between the drive disk and the transmission disk, the mating block is fixedly connected to the transmission disk, the inner sidewall of the mating block abuts against the outer peripheral wall of the drive disk, the mating block is a non-magnetic component, the sidewall of the mating block is provided with a mounting hole, and the anti-loosening component is slidably installed in the mounting hole.

[0018] According to some embodiments of the present invention, the anti-loosening detachable structure has a mounting hole that extends radially through the transmission disc.

[0019] According to some embodiments of the present invention, there are multiple anti-loosening detachable structures, including multiple anti-loosening components and multiple mating blocks. The multiple mating blocks are evenly arranged along the circumference of the drive disk, and the anti-loosening components are arranged in one-to-one correspondence with the mating blocks.

[0020] According to some embodiments of the present invention, the anti-loosening detachable structure is such that the mating block and the transmission disc are fixed together by screws.

[0021] According to some embodiments of the present invention, the anti-loosening detachable structure has an annular protrusion on the outer periphery of the transmission disk, and the mating block is placed inside the annular protrusion.

[0022] According to some embodiments of the present invention, the anti-loosening detachable structure, the drive disk and the transmission disk are made of aluminum alloy.

[0023] According to some embodiments of the present invention, the anti-loosening detachable structure has a connecting flange on the side of the transmission disc away from the drive plate, and the connecting flange is fixedly connected to the transmission disc by screws.

[0024] The floating grinding head according to this utility model includes the anti-loosening and detachable structure described in this utility model.

[0025] The floating grinding head according to this utility model has at least the following beneficial effects: By adopting an anti-loosening assembly with a compression spring and a plug-in block, not only can the stability and accuracy of the connection between the transmission disc and the drive disc be guaranteed, but the risk of accidentally disassembling the transmission disc when removing the connecting flange to replace the working element can also be reduced, thereby improving the stability of the entire floating grinding head during operation; when connected to the working element through the connecting flange and in normal working condition, the drive disc, transmission disc, and connecting flange are connected in sequence and move together; when disassembly is required, the connecting flange can be disassembled separately. Because the transmission disc acts as a buffer, the risk of damage to the drive disc due to disassembly and assembly is reduced, simplifying the maintenance process and ensuring the long-term stable operation of the drive disc; the plug-in block is attracted by an external magnetic attraction component, causing the plug-in block to... The floating grinding head allows for easy disassembly of the connecting flange and drive plate by detaching it from the insertion hole. This enables necessary fine-tuning of the connection between the drive plate and the drive plate, improving maintainability and production efficiency. Furthermore, the rapid assembly and disassembly of the floating grinding head significantly enhances production efficiency, especially in situations requiring frequent tool head changes or maintenance. It allows for quick assembly and disassembly, reducing downtime, lowering maintenance costs, and increasing flexibility. Users can flexibly change tool heads according to different processing needs, improving the equipment's flexibility and adaptability. This structural design ensures the motion accuracy and stability of the actuators during operation, guaranteeing high-quality final products. It is particularly suitable for high-precision machining or surface treatment applications in industrial automation, meeting market demands.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] In the field of industrial automation, especially in applications involving high-precision machining or surface treatment, actuators, such as floating grinding heads, are widely used. These actuators are typically driven by a drive disc, which moves the actuating elements, such as grinding heads and brushes, to perform precise movements for grinding and deburring. In related technologies, the internal structure of the actuators is quite intricate. The drive disc, which provides the direct power output to the actuator, is mostly non-removable. Generally, a transmission disc is fixedly connected to the drive disc, and the actuating element is connected to the transmission disc.

[0044] However, the existing application has the following problems:

[0045] 1. Connection displacement: Under prolonged use or vibration, the transmission disc is prone to displacement relative to the drive disc. This directly affects the motion accuracy and stability of the actuator, and consequently the quality of the final product.

[0046] 2. Disassembly error: The actuator and the transmission plate are generally connected by a connecting flange. However, when disassembling the connecting flange, there is a possibility of accidental disassembly or damage to the transmission plate. Since the internal structure of the actuator is relatively precise, frequent disassembly and assembly of the transmission plate will further reduce the motion accuracy of the actuator's drive plate output.

[0047] 3. Insufficient maintainability: In order to improve the stability of the actuator, some applications completely fix the transmission disk and the drive disk. Although this can reduce the risk of loosening and displacement, it also means that replacing and fine-tuning the transmission disk becomes very inconvenient, reducing production efficiency and flexibility.

[0048] To address the aforementioned issues, there is an urgent need in the market for a non-loosening structure that can ensure connection stability while also enabling a quick and easy assembly / disassembly process for routine maintenance and tooling replacement.

[0049] Therefore, such as Figures 1 to 4As shown, the anti-loosening detachable structure proposed in this utility model includes an actuator 100, a transmission disk 200, and an anti-loosening component 300. The actuator 100 is equipped with a drive disk 110, and the transmission disk 200 covers the drive disk 110 and moves together with it. The anti-loosening component 300 is installed on the inner side of the transmission disk 200. Specifically, the outer peripheral wall of the drive disk 110 is provided with a insertion hole 1101. The anti-loosening component 300 includes a compression spring 310 and a insertion block 320. One side of the compression spring 310 abuts against the inner side of the transmission disk 200, and the other end is connected to and drives the insertion block 320 to insert into the insertion hole 1101. Furthermore, the drive disc 110 and transmission disc 200 are non-magnetic components, while the plug-in block 320 is a magnetic component. The plug-in block 320, through a magnetic attraction element located on the outside of the transmission disc 200, moves away from the center of the drive disc 110 and disengages from the plug-in hole 1101, allowing the transmission disc 200 to be removed. It should be noted that the transmission disc 200 and drive disc 110 are connected by an anti-loosening assembly 300 with a compression spring 310 and a plug-in block 320. This not only ensures the stability and precision of the connection between the transmission disc 200 and drive disc 110 but also reduces the risk of accidentally disassembling the transmission disc 200 when removing the connecting flange 500 to replace the operating element. When connected to the actuating element via the connecting flange 500 and in normal working condition, the drive disc 110, transmission disc 200, and connecting flange 500 are connected sequentially and move together. When disassembly is required, the connecting flange 500 can be disassembled separately. Due to the buffer provided by the transmission disc 200, the risk of damage to the drive disc 110 caused by disassembly is reduced, simplifying the maintenance process and ensuring the long-term stable operation of the drive disc 110. This also improves production efficiency and flexibility. Alternatively, the plug-in block 320 can be attracted by an external magnetic attractor, causing the plug-in block 320 to disengage from the plug-in hole 1101, thereby enabling easy disassembly of the connecting flange 500 and the transmission disc 200. This allows for necessary fine-tuning of the connection between the transmission disc 200 and the drive disc 110, improving the maintainability and production efficiency of the equipment and meeting the needs of high-precision machining or surface treatment applications in the field of industrial automation.

[0050] It should be noted that the anti-loosening and detachable structure can be applied to both ends of the actuator 100, for example, referring to... Figure 1 The drive disk 110 is located at the upper end of the actuator 100 and is adapted to connect to the end effector of a robot. In some applications, the end effector flange of a six-axis robot is connected to the drive disk to drive the actuator to move in space to the workpiece to be processed, such as moving it to the vicinity of the workpiece (not shown in the figure). For example, see reference... Figure 2 The drive disk 110 is located at the lower end of the actuator 100 and is adapted to connect with an actuating element, such as a grinding head or brush, used for grinding and deburring, to perform machining and grinding on the workpiece. For example, refer to... Figure 3Both ends of the actuator 100 are equipped with a detachable structure to prevent loosening.

[0051] Optionally, the transmission disc 200 and the drive disc 110 are fixedly connected by pins or screws. For example, pins are provided on the end faces of the transmission disc 200 and the drive disc 110 for positioning or interference fit. Alternatively, countersunk screw holes are provided on the end face of the transmission disc 200 away from the drive disc 110, and the transmission disc 200 and the drive disc 110 are fixed by screws located in the countersunk screw holes. Furthermore, in addition to the insertion block 320 being fixed to the insertion hole 1101, the pins or screws provide additional stability, preventing unnecessary movement during operation, and also facilitating assembly and disassembly. Moreover, the use of pins or screws further enhances the overall strength of the anti-loosening structure, making the entire device more reliable and reducing maintenance frequency.

[0052] Refer to Figures 1 to 3 In some embodiments of this utility model, an arc-shaped mating block 400 is provided between the drive disk 110 and the transmission disk 200. The mating block 400 is fixedly connected to the transmission disk 200, and the inner sidewall of the mating block 400 abuts against the outer peripheral wall of the drive disk 110, which helps to form a tighter contact surface between the transmission disk 200 and the drive disk 110, increasing the stability of the connection. Specifically, the mating block 400 is a non-magnetic component, and the sidewall of the mating block 400 is provided with a mounting hole 401. The anti-loosening component 300 is slidably installed in the mounting hole 401. By sliding the mounting hole 401, it is ensured that the plug-in block 320 can be smoothly inserted into and withdrawn from the plug-in hole 1101, realizing a quick and simple disassembly and assembly process. In addition, the use of a non-magnetic mating block 400 can avoid magnetic interference with the mating block 400, and does not affect the movement of the plug-in block 320 guided by the magnetic attraction component during disassembly. Optionally, the mounting hole 401 is provided radially through the transmission disk 200 to facilitate the installation and removal of the anti-loosening component 300, while ensuring that the movement direction of the insertion block 320 is perpendicular to the axis of the drive disk 110, which helps improve the fitting accuracy between the insertion block 320 and the insertion hole 1101. Furthermore, there are multiple anti-loosening components 300 and mating blocks 400, which are evenly arranged circumferentially along the drive disk 110. The anti-loosening component 300 and the mating blocks 400 are arranged in a one-to-one correspondence, which can improve the stability of the entire system and ensure uniform contact between the transmission disk 200 and the drive disk 110, reducing the possibility of localized wear. Moreover, the evenly distributed mating blocks 400 can also help distribute the load, reducing deformation or damage caused by excessive force at a single point.

[0053] Optionally, the mating block 400 and the transmission disc 200 are fixed together by screws. The screw fixing method facilitates the installation and disassembly of the mating block 400 and the transmission disc 200, while ensuring the reliability of the connection, further improving the maintainability of the entire structure, and making it easy to inspect and replace the mating block 400.

[0054] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the outer periphery of the transmission disc 200 is provided with an annular protrusion 210, and the mating block 400 is placed inside the annular protrusion 210. On the one hand, the design of the annular protrusion 210 helps to limit the position of the mating block 400 and ensure its stability during operation. On the other hand, the annular protrusion 210 can also serve as a guide, facilitating the installation of the mating block 400, and also helping to improve the compactness and aesthetics of the entire device.

[0055] Optionally, the drive disc 110 and transmission disc 200 are made of aluminum alloy, which ensures a lightweight structure while maintaining sufficient strength and rigidity. Additionally, in some embodiments of this invention, see also... Figure 2 A connecting flange 500 is provided on the side of the transmission disc 200 away from the drive plate. The connecting flange 500 is fixedly connected to the transmission disc 200 by screws, which facilitates quick disassembly and assembly and simplifies the maintenance process.

[0056] The floating grinding head according to an embodiment of the present invention includes an anti-loosening detachable structure according to an embodiment of the present invention. By employing an anti-loosening assembly 300 with a compression spring 310 and a plug block 320, not only can the stability and accuracy of the connection between the transmission disc 200 and the drive disc 110 be guaranteed, but the risk of accidentally disassembling the transmission disc 200 when removing the connecting flange 500 to replace the working element can also be reduced, thereby improving the stability of the entire floating grinding head during operation. When connected to the working element through the connecting flange 500 and in normal working condition, the drive disc 110, the transmission disc 200, and the connecting flange 500 are connected in sequence and move together. When disassembly is required, the connecting flange 500 can be disassembled separately. Since the transmission disc 200 acts as a buffer, the risk of damage to the drive disc 110 due to disassembly and assembly is reduced, the maintenance process is simplified, and the long-term stable operation of the drive disc 110 is guaranteed. The plug block 320 is attracted by an external magnetic attractor, causing the plug block 320 to move. The disengagement of the insertion hole 1101 allows for easy disassembly of the connecting flange 500 and the drive plate 200, enabling necessary fine-tuning of the connection between the drive plate 200 and the drive plate 110, thus improving equipment maintainability and production efficiency. Furthermore, the rapid disassembly and assembly of the floating grinding head significantly improves production efficiency, especially in situations requiring frequent tool head changes or maintenance. This allows for quick disassembly and assembly, reducing downtime, lowering maintenance costs, and enhancing flexibility. Users can flexibly change tool heads according to different processing needs, improving equipment flexibility and adaptability. This structural design ensures the motion accuracy and stability of the actuator 100 during operation, guaranteeing high-quality final products. It is particularly suitable for high-precision machining or surface treatment applications in industrial automation, meeting market demands.

[0057] Other components and operations of the floating grinding head according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0058] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
