[0002] In the bending process of sheet metal shells, the accuracy of the bending angle directly affects the assembly performance and appearance quality of the product, thus requiring rigorous inspection. Traditional angle measurement relies heavily on universal protractors, right-angle rulers, or coordinate measuring machines (CMMs). However, handheld measuring tools are easily affected by operator technique, resulting in unstable positioning, large reading errors, and poor repeatability, making it difficult to guarantee measurement consistency. While precision equipment such as CMMs offers high accuracy, they are expensive, complex to operate, and have low inspection efficiency, making them unsuitable for widespread use on production sites. Furthermore, existing methods generally have poor adaptability to workpieces of different sizes and angles, are cumbersome to adjust, and struggle to achieve rapid and intuitive online inspection. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content

[0019] The angle detection device for sheet metal shell bending processing of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.
[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] See Figs. 1-2This embodiment of the sheet metal shell bending angle detection device effectively improves the stability and accuracy of measurement by directly fixing the detection reference to the workpiece surface, avoiding the shaking and errors caused by handheld measurement. It can flexibly adapt to bending parts of different sizes and angles, has strong versatility, and can achieve rapid alignment and contact, simplifying the operation process. Furthermore, it allows for intuitive reading of bending angle values without additional calculations, significantly improving detection efficiency and effectively ensuring sheet metal processing accuracy. In this embodiment, it mainly includes a fixing member 1 that can be fixedly mounted on the outer wall of the sheet metal. The fixing member 1 is an L-shaped structure with the horizontal end at the top. A magnetic base 5 is fixedly mounted on the front side of the fixing member 1. The magnetic base 5 is a mature existing technology and will not be described in detail here. The magnetic base 5 can abut against the outer wall of the sheet metal. The fixing member 1 is fixedly mounted on the sheet metal part by the magnetic base 5. A handle 6 is fixedly mounted on the rear side of the fixing member 1, facilitating the movement of the device.
[0022] To enable the detection of bending angles in sheet metal parts. See [link / reference] Fig. 1 and Fig. 2 In this embodiment, a movable positioning plate 2 is provided on the fixing member 1. A groove 7 is formed at the horizontal end of the fixing member 1, and the length direction of the groove 7 faces the sheet metal part. A slider 8 that can slide within the groove 7 is fixedly provided on the side of the positioning plate 2. A limit block 9 is fixedly provided on the side of the positioning plate 2, and a limit bolt 10 with its bottom end abutting against the top end of the fixing member 1 is vertically threaded on the limit block 9. Pushing the positioning plate 2 causes the slider 8 to slide inside the groove 7 until the positioning plate 2 abuts against the sheet metal part. Then, the limit bolt 10 is rotated so that its bottom end abuts against the top end of the positioning plate 2, thereby fixing the positioning plate 2.
[0023] One end of the positioning plate 2 has a vertically extending movable groove 11. A movable plate 12 is slidably disposed inside the movable groove 11, and a positioning pin 13 is fixedly disposed at the top of the movable plate 12. A movable detection plate 3 is disposed on the positioning plate 2, and the detection plate 3 can abut against the other outer wall of the sheet metal part. The middle part of the detection plate 3 is rotatably disposed on the positioning pin 13. Pushing the detection plate 3 causes it to slide along the movable groove 11 through the positioning pin 13 and the movable plate 12 until the side of the detection plate 3 abuts against the sheet metal part at the corner.
[0024] The positioning plate 2 is equipped with a detection unit 4 adapted to the detection plate 3. The detection unit 4 includes a guide plate 41 fixedly mounted on the side of the moving plate 12. The guide plate 41 is an arc-shaped plate centered on the positioning pin 13. A guide groove 43 is coaxially formed on the guide plate 41, running vertically through it. A guide rod 44 is fixedly mounted at the bottom of the detection plate 3, sliding within the guide groove 43. A scale plate 45 is coaxially fixedly mounted on the side of the guide plate 41, and a pointer 46 adapted to the scale plate 45 is fixedly mounted at the end of the detection plate 3. During the contact between the detection plate 3 and the sheet metal part, the middle of the detection plate 3 rotates around the positioning pin 13, and its end swings due to the sliding of the guide rod 44 within the guide groove 43, causing the pointer 46 to swing on the scale plate 45. When the detection plate 3 is fully in contact with the sheet metal part, the position of the pointer 46 on the scale plate 45 synchronously indicates the current angle value, allowing the operator to directly read the bending angle and complete the detection.
[0025] The method of using the angle detection device for sheet metal shell bending processing of this utility model is as follows: First, the device is easily moved using the handle 6, and the fixing part 1 is fixed on the sheet metal part using the magnetic base 5. Push the positioning plate 2 so that the slider 8 slides inside the slide groove 7 until the positioning plate 2 abuts against the sheet metal part. Then rotate the limiting bolt 10 so that its bottom end abuts against the top end of the positioning plate 2, thereby fixing the positioning plate 2. Push the detection plate 3 so that it slides along the moving groove 11 through the positioning pin 13 and the moving plate 12 until the side of the detection plate 3 abuts against the sheet metal part at the corner. During the process of the detection plate 3 abutting against the sheet metal part, the middle part of the detection plate 3 rotates around the positioning pin 13, and its end swings by sliding the guide rod 44 inside the guide groove 43, thereby causing the pointer 46 to swing on the scale plate 45. When the detection plate 3 is fully abutting against the sheet metal part, the position of the pointer 46 on the scale plate 45 synchronously indicates the current angle value, and the operator can directly read the bending angle to complete the detection.
