Abstract
Description
Technical Field
[0001] This utility model belongs to the field of workpiece positioning and relates to a ring-shaped fixing device based on infrared distance sensing. Background Technology
[0002] In various industrial and mechanical assembly processes, the fixing and positioning of circular components is a common and important task. Circular components are widely used in the assembly of various mechanical components such as bearings, couplings, gears, and seals, and the precise control of their position and angle directly affects the performance and lifespan of the entire assembly system.
[0003] However, existing ring fixing devices often face the following three problems during use: **Insecure Fixation:** Many traditional fixing devices use simple clamping or screw fixing methods, which are prone to loosening or displacement under external forces or vibrations, causing changes in the position of the ring component. This not only affects assembly accuracy but may also lead to mechanical failure. **Inconvenient Adjustment:** Existing fixing devices typically lack flexible adjustment mechanisms, making fine-tuning of the position and angle of the ring component during assembly difficult and time-consuming. Adjustments often require disassembly and reinstallation, increasing operational complexity and time costs. **Poor Adaptability:** In different application scenarios, the size, shape, and operating environment of ring components vary, but many existing fixing devices lack versatility and cannot flexibly adapt to ring components of different specifications and requirements. This often necessitates custom-designed fixing devices for different situations, increasing design and manufacturing costs. **Insufficient Durability and Reliability:** Some fixing devices are prone to wear, aging, or failure during long-term use, especially under high loads or harsh environments, failing to guarantee the long-term stability and reliability of the ring component. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a ring-shaped fixing device based on infrared distance sensing, which solves the problems of existing ring fixing devices being unstable, inconvenient to adjust, and having poor adaptability during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ring-shaped fixing device based on infrared distance sensing, comprising a first ring, a second ring, a motor, a controller, an infrared sensor, and a retraction device. The first ring has an opening facing the second ring, and the second ring is disposed at the opening of the first ring. The retraction device is connected to the first ring and driven by the motor. The controller is electrically connected to the infrared sensor and the motor, and is used to receive the detection signal from the infrared sensor and control the operation of the motor.
[0006] Optionally, it also includes slide rails on both sides of the second ring, with the first ring fixed on the base and the second ring slidably mounted on the slide rails via pulleys.
[0007] Optionally, the retraction device includes a spring, a steel cable, and a spool. One end of the steel cable is fixedly connected to the second ring, and the other end is connected to the spool. The relative position of the first ring and the second ring is adjusted by the retraction and release of the spool.
[0008] Optionally, one end of the spring is fixedly connected to the first ring, and the other end is connected to the second ring to provide a restoring force to assist in the contraction and relaxation of the cable.
[0009] Optionally, there are two infrared sensors, which are distributed on the inner surfaces of the first and second rings, respectively.
[0010] Optionally, the controller includes a data processing module and a motor drive module. The data processing module is used to process the detection signal from the infrared sensor and generate a control signal, while the motor drive module is used to receive the control signal and control the motor to run.
[0011] Optionally, the motor is a stepper motor, which can precisely control the degree of contraction of the contraction device.
[0012] Optionally, anti-slip silicone pads are provided between the first and second rings and the workpiece to improve stability and safety while avoiding damage to the target structure.
[0013] The beneficial effects of this utility model are as follows: This utility model provides a ring-shaped fixing device based on infrared distance sensing, which is suitable for industrial structures of different widths. By detecting the volume parameters of the target through infrared distance sensors, the steel cable retraction adjustment structure of the two ring structures can be adjusted, which facilitates the adjustment of the position and angle of the fixing ring, thereby improving the assembly accuracy and efficiency and reducing safety hazards. At the same time, during the operation in contact with the target, by adding an anti-slip silicone pad in the middle, the stability and safety can be improved without damaging the target structure.

[0022] Please see Figures 1-2This is a ring-shaped fixing device based on infrared distance sensing, comprising a first ring 1, a second ring 2, a motor 8, a controller (not shown), an infrared sensor 3, and a retraction device. The first ring 1 has an opening facing the second ring 2, and the second ring 2 is positioned at the opening of the first ring 1, allowing it to move relative to the first ring 1. The retraction device is connected to the first ring 1 and driven by the motor 8. Specifically, the retraction device includes a spring 4, a steel cable 7, and a reel 9. One end of the steel cable 7 is fixedly connected to the second ring 2, and the other end is connected to the reel 9. The motor 8 drives the reel 9 to rotate, thereby retracting or releasing the steel cable 7, thus adjusting the relative position of the first ring 1 and the second ring 2. One end of the spring 4 is fixedly connected to the first ring 1, and the other end is connected to the second ring 2, providing a restoring force to assist in the retraction and release of the steel cable 7, ensuring the stability and flexibility of the fixing device. The controller is electrically connected to the infrared sensor 3 and the motor 8. Two infrared sensors 3 are distributed on the inner surfaces of the first ring 1 and the second ring 2 respectively (only one is shown in the figure, the other is located symmetrically), used to detect the size and position information of the workpiece 10. The controller includes a data processing module and a motor drive module. The data processing module receives the detection signals from the infrared sensors 3 and generates control signals after processing. The motor drive module receives the control signals and controls the operation of the motor 8, thereby precisely adjusting the distance between the first ring 1 and the second ring 2 to accommodate workpieces 10 of different sizes. It also includes slide rails 6 set on both sides of the second ring 2, and pulleys 5 that cooperate with them. The first ring 1 is fixed on the base (not shown), and the second ring 2 is slidably set on the slide rails 6 through the pulleys 5, so that the second ring 2 can move smoothly along the slide rails 6, further improving the stability and adjustment accuracy of the fixing device.
[0023] In this embodiment, the motor 8 is preferably a stepper motor, which can precisely control the rotation angle and speed of the winding drum 9, thereby precisely controlling the degree of shrinkage of the shrinking device and ensuring that the fixing device can tightly fix the workpiece 10.
[0024] In this embodiment, an anti-slip silicone pad (not shown) is provided between the first ring 1 and the second ring 2 and the workpiece 10 to improve the friction and stability between the fixing device and the workpiece 10, while avoiding damage to the surface of the workpiece 10.
[0025] In use, the workpiece 10 is placed between the first ring 1 and the second ring 2. An infrared sensor 3 automatically generates a detection signal. The data processing module processes this signal, generates a control signal, and transmits it to the motor 8 drive module. The motor 8 drive module then transmits the signal to the motor 8, which drives the winding drum 9 to rotate and tighten or loosen the steel cable 7. A spring 4 provides a rebound force to assist in the contraction and loosening of the steel cable 7. The contraction and release mechanism adjusts the relative position of the first ring 1 and the second ring 2, thereby automatically fixing the workpiece 10. After use, a control command is input via the input device to drive the motor 8 to rotate and loosen the steel cable 7. The spring 4 provides a rebound force to assist in the loosening of the steel cable 7, causing the contraction mechanism to release and adjust the diameter of the first ring 1 and the second ring 2, thus ending the fixing of the workpiece 10.
[0026] The ring-shaped fixing device based on infrared distance sensing provided in this embodiment detects the size and position information of the workpiece using an infrared sensor, and adjusts the distance between the first and second rings by a motor-driven retraction device, achieving high-precision fixing of the workpiece. This device is suitable for industrial structures of varying widths, facilitates adjustment of the position and angle of the fixing rings, improves assembly accuracy and efficiency, and reduces safety hazards. Simultaneously, the inclusion of anti-slip silicone pads ensures improved stability and safety of the fixing device without damaging the workpiece.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
