[0029] Embodiment 1

[0030] Reference Figure 1-Figure 6 As shown, the utility model discloses a device for detecting the number of thread circles of a threaded hole, comprising:

[0031] A first detection component 1, the first detection component 1 comprises a first gantry 11, a first lifting part 12 and a first camera 15, wherein the first lifting part 12 is arranged on the top of the first gantry 11; a first rotating frame 13 is arranged at the bottom of the first lifting part 12, a first adjusting plate 14 is arranged on the first rotating frame 13, the first adjusting plate 14 is hinged to the first rotating frame 13, the first camera 15 is arranged on the first adjusting plate 14, and a first light source 16 is coaxially arranged at the lens end of the first camera 15;

[0032] A second detection component 2, the second detection component 2 comprises a second gantry 21, a second lifting part 22 and a second camera 25, the second lifting part 22 is arranged on the top of the second gantry 21; a second rotating frame 23 is arranged at the bottom of the second lifting part 22, a second adjusting plate 24 is arranged on the second rotating frame 23, the second adjusting plate 24 is hinged to the second rotating frame 23, the second camera 25 is arranged on the second adjusting plate 24, a second light source 26 is arranged on one side of the second camera 25, and the axis of the second light source 26 is inclined to the axis of the lens of the second camera 25;

[0033] The conveying component 3 includes a conveying frame, the first gantry 11 and the second gantry 21 are arranged on the top of the conveying frame along the length direction of the conveying frame, and the lenses of the first camera 15 and the second camera 25 are arranged toward the conveying frame.

[0034] It can be seen that the utility model performs detection through the first detection component 1 and the second detection component 2, wherein the lens end of the first camera 15 in the first detection component 1 is coaxially provided with a first light source 16 for detecting the aperture and concentricity of the threaded hole, and the first adjustment plate 14 is hinged with the first rotating frame 13, and the aperture and concentricity of the threaded hole on the side wall of the fixture can be detected by adjusting the angle of the first adjustment plate 14, and the first rotating frame 13 can rotate to detect the aperture and concentricity of the threaded holes on different side walls and multiple angles of the fixture. The first lifting part 12 and the first gantry 11 realize the three-axis adjustment of the first camera 15XYZ, and the first camera 15 continuously changes its position, which improves the detection accuracy and speeds up the detection efficiency.

[0035] The axis of the lens of the second camera 25 in the second detection component 2 is tilted and arranged with the axis of the second light source 26, and is mainly used to detect the number of threads of the threaded hole, so that the light can penetrate into the hole and clearly capture every detail of the thread. Secondly, the second adjustment plate 24 is used to adjust the angle of the lens of the second camera 25 to detect the threaded holes on the side walls, and the second rotating frame 23 is used to detect the threaded holes on different side walls. Similarly, the second lifting part 22 and the second gantry 21 realize the adjustment of the three-axis direction of the second camera 25XYZ, and the second camera 25 continuously changes its position, which improves the detection accuracy and speeds up the detection efficiency.

[0036] The conveyor frame arranged at the bottom of the first gantry 11 and the second gantry 21 is used to convey the product. The product (jig) is loaded from the loading end of the conveyor frame. When passing through the first gantry 11, the first camera 15 faces the surface of the product to detect the aperture and concentricity of each threaded hole.

The device not only improves the detection efficiency, but also reduces human errors and improves the accuracy and reliability of detection.

[0039] Further, a first linear module 17 is axially arranged at the top of the first gantry 11, and the first lifting part 12 is arranged on the slide of the first linear module 17. The first lifting part 12 includes a second linear module 121, and the second linear module 121 is arranged on the slide of the first linear module 17, and the axis of the second linear module 121 is perpendicular to the axis of the first linear module 17. A first driving source 122 is arranged on the slide of the second linear module 121, and the output end of the first driving source 122 is connected to the first rotating frame 13, and a second driving source 123 is arranged on the first rotating frame 13, and the output end of the second driving source 123 is connected to the first adjusting plate 14.

[0040] Specifically, the entire action is as follows: the first linear module 17 moves along the X direction between the gantries, the first lifting part 12 moves along the Y axis direction on the first linear module 17, and the first camera 15 is connected along the Z axis on the second linear module 121; at the same time, the first driving source 122 rotates to drive the first rotating frame 13 to rotate, thereby realizing multiple side detections, and the second driving source 123 rotates to drive the adjustment plate to move, thereby changing the inclination of the first camera 15 and the first light source 16 with the horizontal plane, thereby facilitating the detection of the aperture and concentricity of the side threaded holes.

[0041] Further, a third linear module 27 is axially arranged at the top of the second gantry 21, and the second lifting part 22 is arranged on the slide of the third linear module 27. The second lifting part 22 includes a fourth linear module 221, and the fourth linear module 221 is arranged on the slide of the third linear module 27, and the axis of the fourth linear module 221 is perpendicular to the axis of the third linear module 27.

[0042] Specifically, the main actions of the second detection component 2 are the same as those of the first detection component 1, which will not be described in detail here; secondly, unlike the first detection component 1, the second light source 26 cooperates with the second camera 25 to detect the number of threaded holes.

[0044] Specifically, in actual operation, the jig is input from the feed port of the conveyor rack. When the jig is transmitted to the first limiting portion 31, the first limiting cylinders 311 on both sides drive the first limiting blocks 313 to clamp the jig. The first clamping cylinder 312 extends to drive the first clamping block 314 to abut against the jig, fixing the jig at the bottom of the first camera 15, and then inspecting the threaded holes on the surface of the jig. This can avoid shaking of the jig during the inspection process, affect the accuracy of the inspection results, and improve the inspection accuracy and efficiency.

[0046] Specifically, the action of the second limiting portion 32 is the same as that of the first limiting portion 31 , which will not be described in detail herein.
