Description

Technical Field

[0001] This utility model relates to the field of saw blade testing technology, specifically a device for testing the smoothness of the end face of an alloy saw blade. Background Technology

[0002] The smoothness of the saw blade end face is mainly detected by a machine vision-based surface defect detection system. The system takes pictures of the saw blade with a camera and compares the captured pictures with preset images of the saw blade to determine whether the saw blade has defects (such as protrusions and cracks).

[0003] However, current alloy saw blade end face smoothness detection devices use a camera to photograph a saw blade. Since the camera needs to be at a considerable distance from the saw blade to capture the entire blade, the image is often unclear due to the distance, making it impossible to detect small cracks and protrusions. Furthermore, only one saw blade can be detected at a time, resulting in low detection efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a device for detecting the smoothness of the end face of an alloy saw blade. This solves the problems of current alloy saw blade end face smoothness detection devices, which use a camera to photograph a saw blade. However, because the camera needs to be at a considerable distance from the saw blade to capture the entire blade, the image is unclear due to the distance, making it impossible to detect small cracks and protrusions.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] This utility model provides a device for detecting the smoothness of the end face of an alloy saw blade. Please refer to [link / reference]. Figure 1-4 It includes a bottom support plate 1, a support column 3 installed on the top of the bottom support plate 1, a support plate 5 sleeved on the support column 3, and a plurality of limiting support pins 51 for the saw blade to be sleeved on the support plate 5. The diameter of the limiting support pins 51 is less than or equal to the hole diameter of the saw blade being photographed, thereby limiting the saw blade. A drive mechanism is installed on both the support column 3 and the support plate 5, and a camera 11 is installed on the drive mechanism; under the action of the drive mechanism, the camera 11 can make circular motion with different diameters.

[0020] A second ring 4 is welded to the bottom of the support plate 5, and a through hole is opened at the center of the support plate 5 for the support column 3 to pass through. The support column 3 passes through the second ring 4 and is fixed to the second ring 4 by bolts.

[0021] The top of the bottom support plate 1 is welded with a first ring 2, the bottom end of the support column 3 is inserted into the first ring 2, and the first ring 2 and the support column 3 are fixed together by bolts.

[0022] The drive mechanism includes a guide rail 6 that is rotatably connected to the support column 3 via a bearing 62. The guide rail 6 is connected to a servo motor 9. Specifically, a pinion 8 is fixedly mounted on the output shaft of the servo motor 9. The pinion 8 meshes with a large gear 7. The large gear 7 is fixedly mounted on the top of the guide rail 6. The servo motor 9 is mounted on a support frame 10, and the support frame 10 is welded to a support plate 5. A slider 12 is slidably connected to the guide rail 6. Specifically, the guide rail 6 has a T-shaped groove 61, and the slider 12 is slidably connected to the inner wall of the T-shaped groove 61. The camera 11 is mounted on the slider 12, and an electric push rod 14 is installed between the slider 12 and the guide rail 6. Specifically, a support block 16 is welded to the bottom of the guide rail 6, and a third ring 15 is welded to the support block 16.

A fourth ring 13 is welded to the slider 12, and the electric push rod 14 is inserted into the inner wall of the fourth ring 13. The fourth rings 13 are fixed together by bolts.

[0023] In practical use: Multiple saw blades are fitted onto the various limiting support pins 51 on the support plate 5, and the camera 11 first takes pictures of the periphery of the saw blades below. Servo motor 9 drives pinion 8 to rotate, which in turn drives gear 7 to rotate. Gear 7 drives guide rail 6 to rotate, and guide rail 6 drives camera 11 to rotate a certain angle. Then servo motor 9 stops, and camera 11 takes another picture. Repeat the above steps until the periphery of each saw blade is photographed. Then the electric push rod 14 retracts, which reduces the rotation radius of the camera, so that the camera 11 is located above the middle of the saw blade, and the middle of all saw blades is captured in the same way. Then the electric push rod 14 continues to retract, so that the camera 11 is located above the inside of the saw blade, completing the shooting operation of the inside of all the saw blades.
