Description

Technical Field

[0001] This utility model relates to the field of rubber ring testing technology, and in particular to a testing device for rubber ring production. Background Technology

[0002] A rubber ring is a ring-shaped sealing component made of rubber material. It achieves sealing, shock absorption, buffering, or connection through elastic deformation, preventing fluid leakage or the intrusion of external impurities. It is widely used in various fields such as industry, automotive, aerospace, medical, and daily life. To ensure the quality, safety, and reliability of rubber rings after production, they are typically placed on a crack detection device for crack testing.

[0003] According to the Chinese patent "Detection Device for Hidden Cracks in Rubber Rings" (authorization announcement number CN220323139U), the device uses a first threaded rod, a threaded hole block, a limiting rod, and a limiting block to work together to stretch and effectively limit the rubber ring, thus facilitating the effective limiting of various types of rubber rings and significantly improving the practicality of the device.

[0004] In the aforementioned application, the rubber ring is stretched by the limiting block and the limiting rod. The limiting block and the limiting rod are in contact with the rubber ring, which can easily block part of the surface of the rubber ring, thus affecting the comprehensive inspection of the rubber ring and consequently affecting the accuracy of the crack detection of the rubber ring. Utility Model Content

[0005] Therefore, it is necessary to provide a testing device for rubber ring production to address the problem that the surface of the rubber ring is easily obscured, thus affecting the comprehensive inspection of the rubber ring.

[0006] The device includes: a crack detection machine, wherein a positioning frame is fixedly connected inside the crack detection machine, a bidirectional lead screw is rotatably connected to the inner wall of the positioning frame, a positioning block is slidably connected to the surface of the positioning frame, and the surface of the bidirectional lead screw is threadedly connected to the inner wall of the positioning block; and an anti-obstruction mechanism, wherein the anti-obstruction mechanism includes a positioning rod rotatably connected to the inner wall of the positioning block, a transparent frame is fixedly connected to one end of the positioning rod, a transparent block is hinged to the upper end of the inner wall of the transparent frame, and a locking rod is slidably connected to the inner wall of the positioning block, the surface of the locking rod being engaged with the inner wall of the positioning rod.

[0007] In one embodiment, a rubber block is slidably connected to the upper end of the inner wall of the transparent frame, and the surface of the rubber block is slidably connected to the inner wall of the transparent block.

[0008] In one embodiment, a spring is fixedly connected to one end of the locking rod, and the other end of the spring is fixedly connected to the inner wall of the positioning block. The spring pushes the locking rod to move automatically within the positioning block and engage with the positioning rod, thereby limiting the positioning rod and ensuring that the transparent frame and transparent block stably and transparently limit the rubber ring, thus ensuring the accuracy of rubber ring crack detection.

[0009] In one embodiment, an arc-shaped block is fixedly connected to one side of the positioning block, and the surface of the positioning rod contacts the surface of the arc-shaped block. The arc-shaped block precisely limits the rotation angle of the positioning rod, ensuring that the locking rod is accurately locked inside the positioning rod.

[0010] In one embodiment, a mounting block is fixedly connected to the front end of the positioning block, and a blocking block is slidably connected to the inner wall of the mounting block.

[0011] In one embodiment, a toggle block is fixedly connected to the surface of the lever. The toggle block is limited by the cooperation of the mounting block and the blocking block, preventing the spring's elastic force from pushing the lever to move.

[0012] In one embodiment, a limiting block is fixedly connected to the top of the rubber block, and the surface of the limiting block is slidably connected to the inner wall of the transparent frame and the transparent block in sequence.

[0013] In one embodiment, both the transparent frame and the transparent block are acrylic sheet components, and the surface of the transparent frame is U-shaped.

[0014] Beneficial effects 1. By cooperating with the transparent frame and the transparent block, the rubber ring is transparently limited, avoiding obstruction of the rubber ring surface, thus ensuring comprehensive inspection of the rubber ring. By rotating the positioning rod inside the positioning block, the positions of the transparent frame, the transparent block and the sealing ring are adjusted, improving the comprehensive inspection of the rubber ring and thus ensuring the accuracy of rubber ring crack detection. 2. By sliding the rubber block into the transparent frame and the transparent block, the transparent block is locked inside the transparent frame, ensuring that the transparent block and the transparent frame provide stable transparent positioning of the rubber ring, preventing the rubber ring from falling off the surface of the transparent frame, and thus ensuring the accuracy of the detection of cracks in the rubber ring.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a testing device for rubber ring production.

[0020] In one embodiment, a testing device for rubber ring production includes: a crack inspection machine 100, a positioning frame 200 fixedly connected inside the crack inspection machine 100, a bidirectional lead screw 300 rotatably connected to the inner wall of the positioning frame 200, a positioning block 400 slidably connected to the surface of the positioning frame 200, and the surface of the bidirectional lead screw 300 threadedly connected to the inner wall of the positioning block 400; and an anti-obstruction mechanism 500, including a positioning rod 503 rotatably connected to the inner wall of the positioning block 400, a transparent frame 501 fixedly connected to one end of the positioning rod 503, a transparent block 502 hinged to the upper end of the inner wall of the transparent frame 501, a locking rod 504 slidably connected to the inner wall of the positioning block 400, and the surface of the locking rod 504 locking into the inner wall of the positioning rod 503. The transparent frame 501 and the transparent block 502 are both acrylic sheet components, and the surface of the transparent frame 501 is U-shaped.

[0021] It should be noted that the crack inspection machine 100 model can be the In-Sight 7000 series.

[0022] In this embodiment, when crack detection of the rubber ring is required, the bidirectional lead screw 300 is rotated so that the two positioning blocks 400 are positioned at a suitable distance from each other on the surface of the positioning frame 200. The bidirectional lead screw 300 is then stopped, and the transparent block 502 is pulled to open the top of the transparent frame 501. At this time, the rubber ring is placed on the two transparent frames 501, and the transparent block 502 is pushed to flip and abut against the transparent frame 501, thereby sealing the top of the transparent frame 501 and making the rubber ring transparently limited on the two transparent frames 501.

[0023] The PLC controller on the crack detection machine 100 is used to adjust parameters such as focal length, aperture, and exposure time of the camera to ensure clear and complete images of the rubber ring are acquired. The acquired raw images are preprocessed, including noise reduction, contrast enhancement, and sharpening, to improve image quality and facilitate subsequent crack identification. Image processing algorithms, such as edge detection, threshold segmentation, and morphological processing, are used to analyze the preprocessed image and identify cracks on the rubber ring surface. By setting appropriate thresholds and rules, cracks are separated from the background, and their location and size are marked. Based on preset crack judgment criteria, the identified cracks are evaluated and judged. If parameters such as crack length, width, and number exceed the specified thresholds, the rubber ring is determined to have a crack defect.

[0024] When the bottom of the rubber ring needs to be cracked, push the two locking rods 504 away from the inside of the corresponding positioning rods 503, rotate the two positioning rods 503, so that the rubber ring, transparent frame 501 and transparent block 502 rotate, so that the bottom of the rubber ring faces the camera, and the crack detection can be performed on the bottom of the rubber ring.

[0025] like Figure 4 As shown, a rubber block 510 is slidably connected to the upper end of the inner wall of the transparent frame 501, the surface of the rubber block 510 is slidably connected to the inner wall of the transparent block 502, and a limiting block 511 is fixedly connected to the top of the rubber block 510. The surface of the limiting block 511 is slidably connected to the inner walls of the transparent frame 501 and the transparent block 502 in sequence.

[0026] In this embodiment, the transparent block 502 flips inside the transparent frame 501, thereby sealing the top of the transparent frame 501, pushing the rubber block 510, causing the rubber block 510 and the limiting block 511 to move laterally within the transparent frame 501 and the transparent block 502, thereby locking the transparent block 502.

[0027] like Figure 3 and Figure 5As shown, a spring 505 is fixedly connected to one end of the locking rod 504, and the other end of the spring 505 is fixedly connected to the inner wall of the positioning block 400. An arc-shaped block 506 is fixedly connected to one side of the positioning block 400. The surface of the positioning rod 503 contacts the surface of the arc-shaped block 506. A toggle block 507 is fixedly connected to the surface of the locking rod 504. An installation block 508 is fixedly connected to the front end of the positioning block 400. A blocking block 509 is slidably connected to the inner wall of the installation block 508.

[0028] In this embodiment, pulling the blocking block 509 upward within the mounting block 508 pushes the actuating block 507 to move, causing the locking rod 504 to move away from the positioning rod 503. This pushes the blocking block 509 downward and against one side of the actuating block 507, thereby limiting the locking rod 504. Rotating the positioning rod 503 changes the position of the transparent frame 501, transparent block 502, and rubber ring. The positioning rod 503 rotates and abuts against the surface of the arc-shaped block 506, pulling the blocking block 509 upward, causing the blocking block 509 to move upward within the mounting block 508 away from the actuating block 507. At this time, the limitation on the actuating block 507 is released, and the elastic force of the spring 505 pushes the locking rod 504 to move automatically within the positioning block 400 and lock it within the positioning rod 503, thereby locking the positioning rod 503.

[0029] Working principle: Pulling the transparent block 502 opens the top of the transparent frame 501. At this time, the rubber ring is placed on the two transparent frames 501. Pushing the transparent block 502 to flip and abut against the transparent frame 501 pushes the rubber block 510 to slide into the transparent frame 501 and the transparent block 502, thereby stabilizing and sealing the top of the transparent frame 501, and making the rubber ring transparently limited on the two transparent frames 501.

[0030] The positioning rod 503 rotates and abuts against the surface of the arc-shaped block 506, thereby changing the position of the transparent frame 501, the transparent block 502 and the rubber ring, pulling the blocking block 509 upward, so that the blocking block 509 moves upward away from the toggle block 507 in the mounting block 508. At this time, the limit on the toggle block 507 is released, and the elastic force of the spring 505 pushes the locking rod 504 to move automatically in the positioning block 400 and lock in the positioning rod 503, thereby locking the positioning rod 503.

[0031] It should be noted that the crack inspection machine 100, positioning frame 200, bidirectional lead screw 300, positioning block 400 and spring 505 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the crack inspection machine 100 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
