[0031] Following the above technical solution, the following are specific embodiments of this utility model. It should be noted that this utility model is not limited to the following specific embodiments, and all equivalent modifications made based on the technical solution of this application fall within the protection scope of this utility model.

[0032] Example:

[0033] This embodiment provides a detection device capable of measuring various chamfers, such as... Figure 1As shown, it includes a base plate 1, and a displacement measuring plate 2 that can move longitudinally back and forth is installed on the top of the base plate 1. A slide rod guide seat 3 is fixedly connected to the top of the displacement measuring plate 2. A slide rod 4 arranged longitudinally is provided in the slide rod guide seat 3. The slide rod 4 can move longitudinally back and forth relative to the slide rod guide seat 3.

[0034] like Figure 1 As shown, the front and rear ends of the slide rod 4 pass through the front and rear ends of the slide rod guide seat 3 respectively. The slide rod 4 is set parallel to the displacement measuring plate 2 and is arranged longitudinally. The longitudinal front end of the slide rod 4 is rotatably connected to the front end of the angle positioning rod 5.

[0035] like Figure 1 As shown, a groove 10 is provided on the angle positioning rod 5 along the length direction of the angle positioning rod 5. The top and bottom of the groove 10 are open in the vertical direction, and the two ends of the groove 10 in the length direction are closed. The groove 10 is located on the angle positioning rod 5 near the rear end of the angle positioning rod 5.

[0036] like Figure 1 As shown, an angle plate 6 is also fixedly installed on the displacement measuring plate 2. The 0° side of the angle plate 6 is set parallel to the slide rod 4. A locking screw mounting nut 8 is set at the right angle position of the angle plate 6. The vertical central axis of the locking screw mounting nut 8 passes through the vertex of the central angle of the angle plate 6.

[0037] like Figure 1 As shown, the angle positioning rod 5 and the angle disk 6 are connected by a vertically installed locking screw 9. The angle positioning rod 5 is located at the vertical top of the angle disk 6. The locking screw 9 passes vertically through the slide groove 10 and is connected to the locking screw mounting nut 8. When the locking screw 9 is not locked, the angle positioning rod 5 can slide relative to the locking screw 9 through the slide groove 10. The angle positioning rod 5 can rotate around the vertex of the central angle of the angle disk 6 under the action of the slide rod 4.

[0038] like Figure 1 As shown, a right-angled chamfered positioning notch 101 is provided on the front right side of the base plate 1; the transverse sidewall of the right-angled chamfered positioning notch 101 is perpendicular to the slide rod 4, and the longitudinal sidewall of the right-angled chamfered positioning notch 101 is parallel to the slide rod 4.

[0039] In this embodiment, a slide rod 4 and an angle positioning rod 5 are used to achieve multi-angle positioning, enabling the measurement of chamfer dimensions within different process requirements. The slide rod guide seat 3 prevents errors caused by movement during measurement.

[0040] In this embodiment, after the angle is adjusted, the slide rod guide seat 3 is used to fix the slide rod 4 to prevent the slide rod 4 from shifting during measurement.

[0041] As a preferred embodiment of this invention, such as Figure 1As shown, the angle disk 6 is a fan-shaped angle disk with graduations; the central angle of the angle disk 6 is a right angle.

[0042] As a preferred embodiment of this invention, such as Figure 1 As shown, the longitudinal front end of the slide rod 4 and the front end of the angle positioning rod 5 are rotatably connected by the connecting screw 11; the rotation center of the angle positioning rod 5 coincides with the central axis of the connecting screw 11.

[0043] As a preferred embodiment of this invention, such as Figure 2 As shown, the slide guide seat 3 includes a box 301 that is open at both ends in the longitudinal direction. The bottom of the box 301 is fixedly connected to the top of the displacement measuring plate 2. A spring pressure plate 302 is provided on the inner side of the left side wall of the box 301 in the transverse direction. The spring pressure plate 302 is fixedly connected to one end of a plurality of transversely arranged springs 303. The other end of each spring 303 is fixedly connected to one side of the left anti-slip pad 304.

[0044] like Figure 2 As shown, a sliding rod fastening screw hole 305 is provided in the middle of the left side wall of the housing 301, which runs through both sides of the left side wall, and a sliding rod fastening screw 306 is provided in the sliding rod fastening screw hole 305.

[0045] like Figure 2 As shown, the inner side of the right side wall of the box 301 is fixedly connected to one side of the right anti-slip pad 307.

[0046] like Figure 2 As shown, both the left anti-slip pad 304 and the right anti-slip pad 307 are parallel to the slide bar 4.

[0047] In this embodiment, rotating the slide bar fastening screw 306 enables the spring pressure plate 302 to move linearly in one direction to press the spring 303, so that the slide bar 4 is in contact with both the left anti-slip pad 304 and the right anti-slip pad 307. The left anti-slip pad 304 and the right anti-slip pad 307 prevent the slide bar 4 from moving during the measurement process.

[0048] As a preferred embodiment of this invention, such as Figure 1 As shown, a contact sensor 102 is provided at the right-angle vertex of the right-angle chamfered positioning notch 101.

[0049] As a preferred embodiment of this invention, such as Figure 1 As shown, a digital displacement measuring device 7 is also provided on the base plate 1. The digital displacement measuring device 7 is equipped with a displacement sensor. The digital displacement measuring device 7 measures the displacement of the displacement measuring plate 2 through the displacement sensor.

[0050] In this embodiment, the contact sensor 102 is a commonly used contact sensor 102. The sensing point of the contact sensor 102 coincides with the right-angle vertex of the right-angle chamfered positioning notch 101.

[0051] In this embodiment, the digital displacement measuring device 7 is a commonly used digital displacement measuring device.

[0052] In this embodiment, the displacement sensor is a commonly used displacement sensor.

[0053] The device in this embodiment includes the following steps during use:

[0054] Step 1, Measure the angle:

[0055] Operate the slide guide seat 3, loosen the slide fastening screw hole 305, the spring pressure plate 302 moves linearly to the left, release the pressure of the spring 303, the left anti-slip pad 304 and the right anti-slip pad 307 separate, slide the slide rod 4, so that the slide rod 4 can move linearly back and forth.

[0056] The right-angle chamfer positioning notch 101 is aligned with the two right-angled sides of the chamfer to be measured to ensure stability. The sliding rod 4 is slidable, causing the angle positioning rod 5 to rotate. When the angle positioning rod 5 is aligned with the chamfer to be measured, the sliding rod 4 is locked by the sliding rod fastening screw 306 in the sliding rod guide seat 3, and the angle positioning rod 5 is locked onto the angle plate 6 by the locking screw 9. At this point, the angle on the angle plate 6 corresponding to the central axis of the angle positioning rod 5 is the angle of the chamfer to be measured. This allows us to determine whether the angle of the chamfer to be measured matches the chamfer angle required by the process. After confirming that the angle matches the process angle, the depth of the chamfer to be measured is further measured.

[0057] Step 2, Locate and measure:

[0058] Based on step one, the right-angle chamfer positioning notch 101 is again aligned with the two right-angled sides of the chamfer to be measured to ensure stability. The displacement measuring plate 2 is slid forward. When the angle positioning rod 5 first contacts the contact sensor 102 and the contact sensor 102 indicates contact (i.e., when the angle positioning rod 5 first contacts the right-angle vertex of the right-angle chamfer positioning notch 101), the digital displacement measuring device 7 is zeroed. Then, the displacement measuring plate 2 is slid forward again. When the angle positioning rod 5 is aligned with the chamfer to be measured again, the displacement reading on the digital displacement measuring device 7 is the depth of the chamfer to be measured.

[0059] Step 3, Repeat the measurement

[0060] Repeat steps one and two to measure the same location. Perform repeated measurements to ensure that the chamfer size is correct. At the same time, take the average value of the chamfer depth to complete the measurement of the chamfer size.
