[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figures 1-4. This utility model provides a technical solution: a tool for checking the mesh size of a honeycomb ceramic carrier for automotive exhaust purification, including a square perforated plate 1, and further including: a fixing component 2 fixedly connected to the top of the square perforated plate 1, and an observation component 3 fixedly connected to the center of the fixing component 2. The square perforated plate 1 is placed on the honeycomb ceramic carrier to be tested, ensuring that the square holes are in close contact with the surface of the honeycomb ceramic carrier. Then, the position of the square perforated plate 1 relative to the honeycomb ceramic carrier is fixed by the fixing component 2, ensuring that the square perforated plate 1 is placed in the center. Then, it can be observed through the observation component 3, and the number of holes within the square hole range (i.e., one inch × one inch) of the square perforated plate 1 is directly counted to obtain the mesh size of the honeycomb ceramic carrier. The square perforated plate 1 is made of stainless steel, which has excellent corrosion resistance and durability. A square hole with a precise size of 25.4 mm × 25.4 mm (i.e., one inch) is drilled in the middle of the tool for precise alignment and observation of the hole distribution on the surface of the honeycomb ceramic carrier.
[0023] The fixing assembly 2 includes a fixing frame 21. A guide rod 22 is fixedly connected to the inner side of the fixing frame 21. A sliding frame 23 is slidably connected to the outer wall of the guide rod 22. A movable rod 24 is rotatably connected to the outer side of the sliding frame 23. A clamping rod 26 is rotatably connected to the end of the movable rod 24 away from the sliding frame 23. A compression spring 25 is fixedly connected to the top of the sliding frame 23. The bottom of the fixing frame 21 is fixedly connected to the top of the square perforated plate 1. The observation assembly 3 is located directly above the square perforated plate 1. The top end of the clamping rod 26 is rotatably connected to the outer side of the fixing frame 21, and the top end of the compression spring 25 is rotatably connected to the fixing frame 21. The inner side of the fixed connection of 1 is used to fix the square perforated plate 1. First, the sliding frame 23 is slid upward along the guide rod 22, which drives the bottom end of the movable rod 24 to move upward together, forcing the compression spring 25 to be compressed. At this time, under the restriction of the fixed frame 21, the top end of the movable rod 24 can open the clamping rod 26. Then, with the help of the elastic force of the compression spring 25, it can be locked on the outside of the honeycomb ceramic carrier, so that the square perforated plate 1 is placed in the center on the honeycomb ceramic carrier, ensuring the stability of observation and counting, avoiding repeated observation and counting due to the shaking of the perforated plate, and improving the reliability of detection.
[0024] The observation component 3 includes a rotating cylinder 31. A magnifying glass 32 is fixedly connected to the bottom of the rotating cylinder 31, and a rotating ring 33 is fixedly connected to the top of the rotating cylinder 31. A fixed cylinder 35 is slidably connected to the inner side of the rotating ring 33. An observation lens 36 is fixedly connected to the top of the fixed cylinder 35, and a threaded ring 34 is fixedly connected to the bottom of the fixed cylinder 35. The outer side of the fixed cylinder 35 is fixedly connected to the center of the fixed frame 21. The outer wall of the threaded ring 34 is threadedly connected to the inner wall of the rotating cylinder 31. The rotating cylinder 31 is rotated by the rotating ring 33, and the rotating cylinder 31 moves up and down along the threaded ring 34 at the bottom of the fixed cylinder 35, thereby adjusting the distance between the magnifying glass 32 and the surface of the honeycomb ceramic carrier to achieve the best magnification observation effect. In the actual observation process, the magnifying glass 32 and the observation lens 36 work together. The user can adjust the focal length of the magnifying glass 32 to make the holes clearly visible in the field of view, and finally accurately determine the mesh count of the honeycomb ceramic carrier.
[0025] In use, the square perforated plate 1 is placed on the honeycomb ceramic carrier to be tested, ensuring that the square holes are in close contact with the surface of the honeycomb ceramic carrier. Then, the position of the square perforated plate 1 relative to the honeycomb ceramic carrier is fixed by the fixing component 2, ensuring that the square perforated plate 1 is centered. Then, it can be observed by the observation component 3. The number of holes within the square hole range (i.e., one inch × one inch) of the square perforated plate 1 is directly counted to obtain the mesh count of the honeycomb ceramic carrier. The square perforated plate 1 is made of stainless steel, which has excellent corrosion resistance and durability. A square hole with a precise size of 25.4 mm × 25.4 mm (i.e., one inch) is drilled in the middle of the tool for precise alignment and observation of the hole distribution on the surface of the honeycomb ceramic carrier.
[0026] When fixing the square perforated plate 1, first slide the sliding frame 23 upward along the guide rod 22, which drives the bottom end of the movable rod 24 to move upward together, forcing the compression spring 25 to be compressed. At this time, under the restriction of the fixing frame 21, the top end of the movable rod 24 can open the clamping rod 26. Then, with the help of the elastic force of the compression spring 25, it can be locked on the outside of the honeycomb ceramic carrier, so that the square perforated plate 1 is placed in the center on the honeycomb ceramic carrier, ensuring the stability of observation and counting, avoiding repeated observation and counting due to the shaking of the perforated plate, and improving the reliability of detection.
[0027] Rotating the rotating cylinder 31 via the rotating ring 33 causes the rotating cylinder 31 to move up and down along the threaded ring 34 at the bottom of the fixed cylinder 35, thereby adjusting the distance between the magnifying glass 32 and the surface of the honeycomb ceramic carrier to achieve the best magnification observation effect. In actual observation, the magnifying glass 32 and the observation lens 36 work together, and the two cooperate with each other. The user can adjust the focal length of the magnifying glass 32 to make the holes clearly visible in the field of view, and finally accurately determine the mesh count of the honeycomb ceramic carrier.
