Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring detection, and more particularly to a sealing ring chain detection device. Background Art

[0002] In the chain manufacturing industry, especially in applications involving high-precision chain assembly (such as automotive and industrial equipment), the use of sealing ring chains is extremely common. The main function of the sealing ring is to enhance the sealing performance of the chain, prevent impurities such as dust and moisture from entering the chain, and extend the service life of the chain. However, there are some common difficulties and problems in the sealing ring assembly process, which are mainly reflected in the following aspects:

[0003] 1. The sealing ring assembly position is concealed

[0004] Sealing rings are typically installed between the inner and outer links of a chain. Due to their relatively hidden location, traditional visual inspection can be difficult to detect issues like missing or damaged seals. Minor defects during assembly, such as missing, incorrect, or incomplete installation, can be difficult to detect visually after assembly.

[0005] 2. Manual inspection has low efficiency and high error rate

[0006] On traditional production lines, seal ring inspection relies primarily on manual labor, but this is susceptible to factors such as fatigue and lack of concentration, resulting in high error rates. Furthermore, manual inspection speed is limited, making it difficult to meet the efficiency requirements of high-speed production lines.

[0007] 3. High testing costs

[0008] If a full inspection method is adopted (i.e., each chain is inspected in detail), it will not only increase production costs but also reduce production efficiency. In this case, the use of automated inspection equipment can improve production efficiency and reduce costs while ensuring quality.

[0009] 4. Machine failure and sealing ring material problem

[0010] During the assembly process, problems such as ring defects (e.g., substandard materials) or equipment failures (e.g., assembly machinery malfunctions) can lead to ring shortages or broken rings. If these problems are not discovered and corrected in a timely manner, they can affect the overall quality of the chain product.

[0011] 5. Industry standards and quality requirements

[0012] As industry demands for higher product quality increase, the quality and assembly precision of seals are also becoming increasingly demanding, especially in automotive and heavy industrial applications. Chain durability, stability, and sealing directly impact the safety and performance of equipment, necessitating an efficient and precise inspection method to ensure assembly quality.

[0013] Therefore, a detection method using sensors becomes an effective solution. Utility Model Content

[0014] To overcome the shortcomings of existing technologies, this utility model provides a seal ring chain detection device. When a seal ring is missing or defective, a copper plate moves inward a certain distance under the action of a spring. This displacement causes the slide rail to move. A proximity switch detects this change and triggers an alarm, indicating a problem with the assembly process. The device incorporates three copper plates, allowing it to simultaneously detect the presence of both seal rings and the large pipe on the chain.

[0015] To achieve the above objectives, the present invention provides the following technical solutions, which mainly include:

[0016] A sealing ring chain detection device, suitable for a chain assembly production line, comprises a channel for a precision chain to pass through, and a detection structure arranged along the channel; the detection structure is provided with a detection block that moves perpendicularly to the chain's travel direction;

[0017] The detection block includes a contact piece that slides in contact with the surface of the chain sealing ring and an automatically reset spring. The reset spring allows the contact piece to always contact the chain sealing ring, and is used to determine the missing state of the sealing ring through the movement trajectory of the detection block.

[0018] In a specific embodiment, the channel is provided with a baffle slightly higher than the precision chain, and the detection structure is provided on the other side of the chain.

[0019] In a specific embodiment, the detection block includes a pad and a copper sheet placed on the top of the pad. The pad is installed on a slide rail. The detection block moves along the slide rail as a whole, and the moving direction is perpendicular to the channel.

[0020] In a specific embodiment, three groups of the detection blocks are provided, and the pads are provided with corresponding heights according to the positions of the sealing rings, corresponding to the upper sealing ring, the large tube and the lower sealing ring respectively.

[0021] In a specific embodiment, one end of the return spring is fixed to the baffle by a pin, and the other end is arranged on the detection block, providing a force to pull the chain when the detection block moves outward.

[0022] In a specific embodiment, a proximity switch is provided at a position of the detection block away from the chain, for detecting the movement of the slide rail and issuing an alarm.

[0023] It can be seen from the above technical solution that, compared with the prior art, the present invention realizes early detection of missing or damaged sealing rings through structural design, and has the following advantages:

[0024] 1. Real-time detection: The device can automatically detect missing rings during the assembly process to avoid errors caused by manual detection.

[0025] 2. High precision: The combined effect of copper sheet, spring and proximity switch makes the detection results more accurate.

[0026] 3. Improve efficiency: Automated testing reduces the need for manual testing on the production line, improves production efficiency and reduces quality management costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1

[0032] This embodiment discloses a sealing ring chain detection device, which is suitable for a chain assembly production line and is used to detect the missing of sealing rings during the chain assembly process in real time to improve assembly quality and production efficiency. The device includes a channel adapted for a precision chain and a detection structure arranged along the channel. A baffle 3 slightly higher than the chain is provided in the channel to ensure the smooth passage of the chain while providing support for the detection structure. The detection structure is installed in the direction of chain travel and arranged perpendicular to the direction of chain movement. It is equipped with a movable (vertically reversed along the direction of chain travel) detection block. The detection block consists of a contact piece (copper piece 4) for contacting the surface of the chain sealing ring 9 and a reset spring 1. The reset spring 1 always presses the contact piece against the surface of the sealing ring 9 to ensure that the detection block can automatically track the state of the sealing ring 9 when the chain is moving.

[0033] In this device, the detection block is fixed to a movable slide rail 7, allowing it to move smoothly along the rail. The detection block's return spring 1 has one end fixed to a baffle 3 and the other end connected to the detection block itself. The spring's design ensures that the detection block maintains contact with the sealing ring 9 on the chain surface at all times. If the sealing ring 9 is lost, the detection block will move inward a certain distance under the action of the spring. This displacement is detected by a proximity switch 6 at the end of the slide rail 7, which generates an alarm signal, prompting the operator to make timely adjustments to the assembly.

[0034] The device is designed with three sets of detection blocks, one for checking the seals above the chain, at the chain's main tube 8, and at the bottom of the chain. The height of each set of detection blocks is adjusted according to the position of the different seals 9, ensuring that the detection blocks correspond to the corresponding detection positions. This structure ensures that each detection point can be effectively monitored, ensuring a correct assembly process. Through the precise coordination of the reset spring 1, the slide rail 7, and the proximity switch 6, the detection blocks can monitor the absence of the seals 9 in real time. After the test is completed, the device automatically resets without human intervention, further enhancing the device's automation level.

[0035] The seal ring chain detection device of this embodiment transforms chain assembly defect detection into an automated process, eliminating manual inspection and improving the inspection efficiency and accuracy of the production line. Through its real-time alarm function, the device quickly responds to missing seal rings during the assembly process, effectively ensuring product assembly quality.
