Description

Technical Field

[0001] This utility model relates to the technical field of lighting equipment for inspection, and more specifically, to a lighting equipment for inspecting the surface defect size of a circular object. Background Technology

[0002] A ring is essentially a hollow circle with a small radius and a large radius. The width of the ring is the difference between the radius of the entire circle and the radius of the hollow circle. After production, the ring workpiece needs to undergo surface defect and dimensional inspection. This process requires lighting equipment to assist in the inspection and observation of the workpiece. However, existing technologies have the following shortcomings:

[0003] When lighting equipment is in use, it is often installed in a designated location. Operators use the lighting equipment for auxiliary lighting. However, the angle and position of the lighting equipment itself are often inconvenient to adjust. If the lighting angle is not appropriate, it may cause reflection or glare on the surface of the object being inspected, affecting the subsequent actual inspection.

[0004] Therefore, there is an urgent need for lighting equipment based on the surface defect size detection of circular objects to solve the above problems. Utility Model Content

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Example:

[0030] like Figure 1-4As shown, the surface defect size detection lighting device for a circular object proposed in this embodiment includes a fixed frame 1. Two guide rods 2 are horizontally arranged on the fixed frame 1, and the guide rods 2 are fixedly connected to the fixed frame 1. The two guide rods 2 are symmetrically distributed about the central axis of the fixed frame 1. A mounting base 3 is slidably connected to both guide rods 2. A connecting shaft 4 is fixedly connected to the mounting base 3. A connecting plate 5 is rotatably sleeved on the connecting shaft 4. A slot 6 is opened on one side surface of the connecting plate 5. A lighting lamp body 7 is fixedly installed on the lower surface of the connecting plate 5. A reduction motor 8 is fixedly installed on one side surface of the mounting base 3. The output of the reduction motor 8... A shaft 9 is fixedly connected to the output end. A rotating plate 10 is fixedly connected to the end of the shaft 9 away from the geared motor 8. When the geared motor 8 is started, the shaft 9 and the rotating plate 10 are rotated. A connecting block 11 located in the slot 6 is fixedly connected to one side surface of the rotating plate 10. Two limiting rings 12 are fixedly sleeved on the connecting shaft 4. The connecting block 11 rotates synchronously with the running trajectory of the rotating plate 10. The connecting block 11 slides in the slot 6, thereby causing the connecting plate 5 to swing back and forth in a fan shape. The lighting body 7 moves synchronously with the connecting plate 5, thereby adjusting the angle of the lighting body 7 and changing the lighting angle.

[0031] like Figure 1 and Figure 4 As shown, the upper surface of the fixing frame 1 has an opening 13, the length of which is greater than four-fifths of the length of the guide rod 2. A threaded rod 14 is fixedly connected to the center of the top of the mounting base 3. A positioning knob 15 is threadedly connected to the threaded rod 14. An anti-slip pad 16 is fixedly connected to the bottom of the positioning knob 15. The anti-slip pad 16 is in contact with the fixing frame 1. The anti-slip pad 16 is made of rubber and has good wear resistance and anti-slip performance. By rotating the positioning knob 15, the anti-slip pad 16 is disengaged from the fixing frame 1. Then, the mounting base 3 is pulled, causing the mounting base 3 to slide on the two guide rods 2. Through the connecting shaft 4 and the connecting plate 5, the lighting body 7 moves synchronously with the connecting plate 5, thereby adjusting the horizontal position of the lighting body 7 to accommodate circular workpieces of different sizes.

[0032] like Figure 1 As shown, the top of the fixing frame 1 is fixedly connected to two symmetrically distributed mounting plates 17. The upper surface of the mounting plates 17 has several mounting holes. By using multiple bolts to cooperate with the multiple mounting holes, the two mounting plates 17 are installed in the designated position to position the fixing frame 1.

[0033] like Figure 1 and Figure 3 As shown, the two limiting rings 12 are symmetrically distributed about the central axis of the connecting shaft 4, and the two limiting rings 12 are respectively attached to the opposite side surfaces of the connecting plate 5. The two limiting rings 12 can limit the connecting plate 5 laterally and prevent the position of the connecting plate 5 from shifting.

[0034] like Figure 1 and Figure 4 As shown, the threaded rod 14 is located inside the opening 13, which allows the threaded rod 14 to move.

[0035] Specifically, in use, this surface defect size detection lighting equipment based on a ring-shaped object operates as follows: Two mounting plates 17 are installed in designated positions to position the fixing frame 1. The reduction motor 8 is electrically connected to an external control power supply. The reduction motor 8 is started, driving the shaft 9 and rotating plate 10 to rotate. The connecting block 11 rotates synchronously along the trajectory of the rotating plate 10, sliding within the slot 6. This causes the connecting plate 5 to swing back and forth in a fan shape. The lighting body 7 moves synchronously with the connecting plate 5, thus adjusting the angle of the lighting body 7. The lighting angle is changed by adjusting the lighting body 7 to a suitable angle, and then the reduction motor 8 stops working. At the same time, by rotating the positioning knob 15, the anti-slip pad 16 is disengaged from the fixing frame 1. Then, the mounting base 3 is pulled, causing the mounting base 3 to slide on the two guide rods 2. Through the connecting shaft 4 and the connecting plate 5, the lighting body 7 moves synchronously with the connecting plate 5, thereby adjusting the horizontal position of the lighting body 7. This makes it easier to adapt to circular workpieces of different sizes, has a wider range of applications, and is beneficial for subsequent inspection of circular workpieces.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
