Description
Technical Field
[0001] This utility model relates to the field of five-axis cradle turntable braking technology, and in particular to a five-axis cradle turntable with stable braking. Background Technology
[0002] A five-axis linkage machine tool is a high-end CNC machining equipment equipped with five motion axes. It achieves high-precision milling of complex curved surface workpieces through multi-axis linkage control and is widely used in aerospace, shipbuilding, mold manufacturing and other fields.
[0003] The five-axis cradle turntable consists of a base, a cradle frame, an A-axis, a C-axis, and a drive control system. The base supports the overall structure and ensures stable operation. The cradle frame connects the workpiece mounting table and the rotary axis, supporting the workpiece and transmitting motion. The A-axis is the tilt axis, driving the frame to rotate around the horizontal axis and adjusting the workpiece tilt angle. The C-axis is the rotation axis, driving the frame to rotate 360° around the vertical axis. The drive control system includes servo motors, reducers, etc., precisely controlling the movement of two axes to achieve multi-axis linkage, improving the accuracy and efficiency of machining complex curved surfaces. The brake of the five-axis cradle turntable mainly consists of a braking assembly and a drive component. The braking assembly includes brake pads, such as hydraulic braking assemblies consisting of oil cylinders and inner and outer brake pads, while pneumatic braking assemblies include brake cylinders. The drive component is commonly a hydraulic station or air source, providing power. When braking is in operation, the drive component causes the braking assembly to actuate, causing the brake pads to grip the rotating components, such as the spindle or rotary axis, to achieve braking, prevent the turntable from rotating unexpectedly, and ensure the stability of the workpiece position during machining.
[0004] In traditional five-axis cradle turntables, the brake pads directly grip the rotating components, which can cause wear and tear on the rotating components over time. Furthermore, the lack of a single brake pad for fixation after braking results in poor stability. If braking is not successful, the cradle frame may rotate, affecting machining accuracy and safety.
[0005] Therefore, it is necessary to provide a five-axis cradle turntable with stable braking to solve the above-mentioned technical problems. Utility Model Content
[0006] This invention provides a five-axis cradle turntable with stable braking, which solves the problems of brake pads directly contacting rotating parts, which accelerates wear, and the poor braking stability of a single brake pad after stopping, which would affect machining accuracy and safety if braking failure occurs.
[0007] To solve the above-mentioned technical problems, the five-axis cradle turntable with brake stability provided by this utility model includes: two bases; A drive structure is installed on the top of one of the bases, and a support tail is installed on the top of the other base. A rotating opening is provided on one side of the support tail, and a rotating component is rotatably connected inside the rotating opening via a bearing. Multiple rotating brake structures are installed on the outer surface of the rotating component. A telescopic assembly is installed on the top of the support tail, and a stationary brake structure is installed at the telescopic end of the telescopic assembly. A magnetic control device is installed on the top of the support tail. A cradle frame is installed between the rotating component and the drive structure. A magnetic suction assembly is installed on the outer surface of the rotating component near one end. The magnetic suction assembly includes a mounting structure and multiple magnetic rings. The mounting structure is installed on the outer surface of the rotating component, and the multiple magnetic rings are installed on the outer surface of the mounting structure. A fixing frame is installed on one side of the support tailstock, and an electromagnet is installed at the bottom of the fixing frame; The positions of the rotary brake structure and the stationary brake structure correspond to each other. The magnetic control device can control the current of the electromagnet, thereby controlling the magnetic force of the electromagnet. After the electromagnet is energized, it generates a magnetic force that attracts the magnet ring with its own magnetic force, thereby fixing the rotating part again. The electromagnet needs to be energized after the rotating part stops. The drive structure includes a bracket.
[0008] Preferably, a control box with a door is installed on the front of the support tail seat, and a warning light is installed on the front of the support tail seat via a fixed base; The warning light illuminates to indicate whether the electromagnet and the magnetic ring are fully engaged.
[0009] Preferably, the rotary brake structure includes a fixing structure and a rotary brake pad, wherein the fixing structure is mounted on the outer surface of the rotating component, and the rotary brake pad is mounted on the outer surface of the fixing structure; The fixed structure can be detached from the outer surface of the rotating component.
[0010] Preferably, the telescopic assembly includes a sealing base and a telescopic component, the sealing base being mounted on top of the supporting tailstock, and the telescopic component being mounted on top of the sealing base; The telescopic component's telescopic end passes through the support tailstock and connects to the stationary brake structure. A pressure sensor needs to be installed at the connection between the stationary brake structure and the telescopic component to monitor pressure changes.
[0011] Preferably, a hydraulic component is installed on the top of the sealing base, and a pressure sensor is installed on the top of the hydraulic component through an injection pipe; The top of the pressure sensor is connected to an oil line with a valve via a pipe.

[0013] Preferably, the bottom of the movable frame and the stationary brake pad has multiple mounting ports, and a monitoring component is installed inside each mounting port.
[0014] Preferably, the monitoring assembly includes a monitoring base and a monitoring component, wherein the monitoring base is installed on the top of the inner wall of the mounting port, and the monitoring component is installed on the bottom of the monitoring base; The monitoring component can be a contact sensor or a pressure sensor.
[0015] Compared with related technologies, the five-axis cradle turntable with braking stability provided by this utility model has the following beneficial effects: This invention provides a five-axis cradle turntable with stable braking. To increase the stability of the five-axis cradle turntable after braking and reduce the wear of rotating components, a rotary brake structure is first installed on the outer surface of the rotating component, with the rotary brake structure and the stationary brake structure corresponding in position. The extension and retraction of the telescopic component allows the stationary brake structure to fit into the rotary brake structure, generating resistance and providing braking force to the rotating component, thus fixing it in place after braking.

At the same time, the cooperation between the stationary brake structure and the rotary brake structure, along with the electromagnet and the magnetic suction component, increases the stability of the rotating component, which is beneficial for improving machining accuracy and safety.

The brake-stabilized five-axis cradle turntable includes: two bases 1; A drive structure 2 is installed on the top of one of the bases 1.

A cradle frame 3 is installed between the rotating component 20 and the drive structure 2. A magnetic suction component 9 is installed on the outer surface of the rotating component 20 near one end. The magnetic suction component 9 includes a mounting structure 901 and multiple magnetic rings 902. The mounting structure 901 is installed on the outer surface of the rotating component 20, and the multiple magnetic rings 902 are installed on the outer surface of the mounting structure 901. A fixing frame 5 is installed on one side of the supporting tail seat 14, and an electromagnet 4 is installed at the bottom of the fixing frame 5; The positions of the rotary brake structure 18 and the stationary brake structure 16 are corresponding. The magnetic control device 7 can control the current applied to the electromagnet 4, thereby controlling the magnetic force of the electromagnet 4. After the electromagnet 4 is energized, it generates magnetic force and attracts the magnet ring 902 with its own magnetic force, thereby fixing the rotating part 20 for the second time. The electromagnet 4 needs to be energized after the rotating part 20 stops. The drive structure 2 includes a bracket, a motor with self-locking and control of rotation angle and speed, and a fixing buckle. The fixing buckle is convenient to connect with the cradle frame 3. The drive structure 2 provides rotational driving force for the cradle frame 3.
[0021] Please refer to Figure 1 A control box 13 with a door 12 is installed on the front of the support tail seat 14, and a warning light 10 is installed on the front of the support tail seat 14 via a fixed base 11. When the warning light 10 illuminates, it can be used to determine whether the electromagnet 4 and the magnet ring 902 are fully engaged, and at the same time, it can be used to determine whether the rotating part 20 is securely fixed.
[0022] Please refer to Figure 3 and Figure 4 The rotary brake structure 18 includes a fixing structure 181 and a rotary brake pad 182. The fixing structure 181 is mounted on the outer surface of the rotating component 20, and the rotary brake pad 182 is mounted on the outer surface of the fixing structure 181. The fixed structure 181 can be removed from the outer surface of the rotating component 20 for easy replacement of the rotating brake pad 182.
[0023] Please refer to Figure 1 and Figure 2The telescopic assembly 8 includes a sealing base 801 and a telescopic component 802. The sealing base 801 is installed on the top of the supporting tailstock 14, and the telescopic component 802 is installed on the top of the sealing base 801.

The sealing base 801 can increase the sealing performance.
[0024] The working principle of the brake-stabilized five-axis cradle turntable provided by this utility model is as follows: First, a rotary brake structure 18 is installed on the outer surface of the rotating component 20, with the rotary brake structure 18 and the stationary brake structure 16 corresponding to each other. The extension and retraction of the telescopic component 8 allows the stationary brake structure 16 to fit with the rotary brake structure 18, generating resistance and thus providing braking force for the rotating component 20. After stopping, the rotating component 20 can be fixed in place. At the same time, a magnetic attraction component 9 is installed on one end of the outer surface of the rotating component 20, with the magnetic attraction component 9 corresponding to the electromagnet 4. The attraction between the electromagnet 4 and the magnetic attraction component 9 increases the stability of the rotating component 20 after stopping. In actual use, when braking or stopping is required, the controller only needs to reduce the rotational driving force of the drive structure 2. At the same time, the extension and retraction of the telescopic component 8 can drive the stationary brake structure 16 to approach the rotary brake structure 18 for braking until it stops. After the rotating component 20 stops completely, the electromagnet 4 is energized and the magnetic force generated by the magnetic control device 7 is controlled to make the electromagnet 4 and the magnetic attraction component 9 close together, providing a stable fixing structure for the rotating component 20. Together with the stationary brake structure 16 and the rotary brake structure 18, the rotating component 20 is firmly fixed in place.
[0025] Compared with related technologies, the five-axis cradle turntable with braking stability provided by this utility model has the following beneficial effects: To increase the stability of the five-axis cradle turntable after braking and reduce the wear of the rotating component 20, a rotary brake structure 18 is first installed on the outer surface of the rotating component 20, with the rotary brake structure 18 and the stationary brake structure 16 corresponding to each other. The extension and retraction of the telescopic component 8 allows the stationary brake structure 16 and the rotary brake structure 18 to fit together, generating resistance and providing braking force for the rotating component 20. After braking, the rotating component 20 can be fixed in place. At the same time, a magnetic suction component 9 is installed on one end of the outer surface of the rotating component 20, with the magnetic suction component 9 and the electromagnet 4 corresponding to each other. The attraction between the electromagnet 4 and the magnetic suction component 9 increases the stability of the rotating component 20 after braking. This design, through the rotary brake structure 18, can increase the protection of the outer surface of the rotating component 20 and reduce wear. At the same time, the cooperation between the stationary brake structure 16 and the rotary brake structure 18, the electromagnet 4, and the magnetic suction component 9 can increase the stability of the rotating component 20, which is beneficial to improving machining accuracy and safety.
[0026] Second Embodiment
[0027] Please refer to the following: Figures 6-7 , Figure 6 A schematic diagram of the second embodiment of the brake-stabilized five-axis cradle turntable provided by this utility model; Figure 7 This utility model provides a structural schematic diagram of the monitoring component. Based on the brake-stabilized five-axis cradle turntable provided in the first embodiment of this application, the second embodiment of this application proposes another brake-stabilized five-axis cradle turntable. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0028] Specifically, the difference between the brake-stabilized five-axis cradle turntable provided in the second embodiment of this application and the following is noted: Please refer to... Figure 6 and Figure 7 A hydraulic component 23 is installed on the top of the sealing base 801, and a pressure sensor 21 is installed on the top of the hydraulic component 23 through an injection pipe 22. The top of the pressure sensor 21 is connected to an oil line with a valve via a pipe, and the pressure sensor 21 can monitor the pressure changes of the oil inside the hydraulic component 23.
[0029] Please refer to Figure 6 and Figure 7 The telescopic end of the hydraulic component 23 is equipped with a movable frame 24, and a stationary brake pad 25 is installed at the bottom of the movable frame 24. The positions of the stationary brake pad 25 and the rotating brake pad 182 correspond to each other.
[0030] Please refer to Figure 6 and Figure 7The bottom of the movable frame 24 and the stationary brake pad 25 has multiple mounting ports 26, and a monitoring component 17 is installed inside each mounting port 26. The mounting port 26 passes through the stationary brake pad 25.
[0031] Please refer to Figure 6 and Figure 7 The monitoring component 17 includes a monitoring base 171 and a monitoring component 172. The monitoring base 171 is installed on the top of the inner wall of the mounting port 26, and the monitoring component 172 is installed on the bottom of the monitoring base 171. The monitoring component 172 can be a contact sensor or a pressure sensor. When the monitoring component 172 comes into contact with the rotating brake pad 182, it can be determined that the stationary brake pad 25 needs to be replaced.
[0032] Compared with related technologies, the five-axis cradle turntable with braking stability provided by this utility model has the following beneficial effects: To monitor the braking accuracy and usage of the stationary brake pad 4, multiple mounting ports 26 are provided at the bottom of the stationary brake pad 25 for mounting the monitoring component 17. The monitoring end of the monitoring component 17 is ensured to be 3-5mm higher than the bottom of the movable frame 24 for monitoring the usage of the stationary brake pad 25. Simultaneously, a pressure sensor 21 is installed at the inlet of the hydraulic component 23 to monitor the oil pressure in real time, improving the extension and contraction accuracy and stability of the hydraulic component 23. During actual use, the stationary brake pad 25 wears down during braking. If the wear reaches a certain level, causing the monitoring end of the monitoring component 17 to contact the rotating brake structure 18, it indicates that replacement is required, and the stationary brake pad 25 needs to be replaced promptly. The pressure sensor 21 also allows for real-time monitoring of the oil pressure, which helps control the stability and accuracy of the extension and contraction of the hydraulic component 23. This design enables real-time monitoring of the usage of the stationary brake pad 25, improves braking accuracy, and enhances braking safety and stability.
[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
