[0002] After the production of automotive parts is completed, burrs may be generated inside the parts. The existence of burrs affects the qualification rate of the parts. Therefore, when detecting the inner hole of automotive parts, it is necessary for workers to hold the endoscope by hand and insert it into the inner hole of the part for detection. This often causes damage to the endoscope or scratches the workpiece, resulting in losses. Secondly, the manual efficiency is too low to meet the production requirements.

[0003] The utility model patent with the Chinese patent application number 201821742320.4 mentions a special fixture for fixing endoscope detection. It is a special fixture for fixing endoscope detection. By placing the automotive parts in a fixed position, the automotive parts move with the part mounting seat and enter the endoscope position to achieve detection. When using the endoscope detection fixing fixture proposed in the above utility model, the part needs to be installed on the part mounting seat. There is a protective cover above the part mounting seat, which limits the volume size and shape of the part to be detected. At the same time, the above utility model realizes detection at other angles by rotating the endoscope. However, the connecting wire at the back of the endoscope restricts the rotation of the endoscope, and long-term rotation will cause damage to the endoscope.

The mobile base 10 can move up and down along the linear guide rail 9. The mobile base 10 is provided with blocks 11 at the top and bottom of the mobile base 10. The blocks 11 limit the up and down movement distance of the mobile base 10 to prevent the clamping part 5 on the mobile base 10 from hitting the bottom plate 2 or the upper plate 6 to cause damage to the clamping part 5. A fixing plate 12 is provided in front of the mobile base 10, and threaded holes are provided at the four corners of the fixing plate 12. The same threaded holes are provided at the corresponding positions of the mobile base 10. A rectangular through hole 17 is provided in the middle of the fixing plate 12, and the clamping part 5 passes through the rectangular through hole 17 to be clamped with the mobile base 10. The fixing plate 12 and the mobile base 10 are fixed by bolts. After the clamping part 5 is fixed, the position of its circular hole corresponds to the middle of the turntable 8. The endoscope 1 is installed at the position of the through hole 17 of the clamping part 5, and the installation angle needs to be adjusted during installation.

[0022] In some embodiments, a through hole 17 is provided in the middle of the upper plate 6 , and a connecting sleeve 13 having a size corresponding to the through hole 17 is fixedly connected to the upper portion of the upper plate 6 .

[0023] In some embodiments, a rotating structure 7 is provided below the turntable 8, and the rotating structure 7 includes: a thin-walled deep groove ball bearing 14, a pulley 15, and a flange 16. A thin-walled deep groove ball bearing 14 corresponding to its axial diameter is provided on the outer side of the connecting sleeve 13, the inner ring of the thin-walled deep groove ball bearing 14 is fixedly connected to the connecting sleeve 13, and the outer ring of the thin-walled deep groove ball bearing 14 can rotate.

[0026] Example 1

[0027] In a specific implementation manner provided by the present utility model, Figures 1 - 4As shown in the figure, the upper plate 6 and the bottom plate 2 are bolted together by columns 3 to form a main frame. The linear guide rail 9 is bolted to the upper plate 6 and the bottom plate 2. A clamping part 5 is installed on the linear guide rail 9. The clamping part 5 passes through the fixing plate 12 and is clamped and fixed by the fixing plate 12. The endoscope 1 is installed in the middle of the clamping part 5, so that the center line of the through hole 17 of the endoscope 1 and the upper plate 6 is on the same horizontal line. The flange 16 is placed above the thin-wall deep groove ball bearing 14 and clamped by the pulley 15. The turntable 8 is arranged above the flange 16. The workpiece 18 to be detected is placed above the turntable 8. When detecting the workpiece 18 to be detected, it is necessary to manually adjust the moving base 10 to adjust the horizontal height of the lens of the endoscope 1. After reaching the height to be detected, rotate the turntable 8 with the other hand to rotate the workpiece 18 to be detected. Observe the inside of the workpiece 18 to be detected through the lens of the endoscope 1. After the detection at the height is completed, manually adjust and continue to raise the height of the moving base 10 to raise the height of the endoscope lens. When burrs are found on the workpiece 18 to be detected by rotating the turntable 8, the operator manually removes the burrs and continues to repeat the above operations. After the above operations are completed, manually lower the moving base 10 along the linear guide rail 9. The stop block 11 of the moving base 10 contacts the bottom plate 2 to complete the detection of the workpiece 18 to be detected once.

[0028] Embodiment 2

[0029] In a specific embodiment provided by the present invention, as Figures 1 - 4 shown, the height of the stop block 11 at the top of the moving base 10 corresponds to the inner cavity height of the workpiece 18 to be detected. Adjust the maximum rising height of the moving base 10 to prevent the endoscope 1 from bumping against the inner wall of the workpiece 18 to be detected.
