[0027] Embodiment one

[0028] The embodiment is a first embodiment of a circular part appearance detection auxiliary device, as shown in Figure 1 and Figure 3 The device comprises a base 1, a fixed column 2, a handle 3 and an abutting piece 4. The fixed column 2 is rotationally connected with the base 1. The handle 3 is detachably connected with the fixed column 2. The handle 3 is coaxially arranged with the fixed column 2. The abutting piece 4 is arranged on the handle 3.

[0029] The device further comprises an elastic member 5 for moving the handle 3 towards the fixed column 2. The two ends of the elastic member 5 are connected with the base 1 and the handle 3 respectively. Figure 2 When placing the part, the handle 3 is pulled to compress the elastic member 5. As shown in Figure 3 , enough space is left to place the part between the fixed column 2 and the abutting piece 4. The handle 3 is released. As shown in , the elastic member 5 drives the handle 3 to automatically connect with the fixed column 2 through the inner circle of the part, realizing quick clamping. At the same time, when rotating the handle 3, the handle 3 and the fixed column 2 are stably connected through the elastic force of the elastic member 5.

[0030] The device further comprises a guide column 6 and an abutting plate 7. The guide column 6 is arranged on the handle 3. The abutting plate 7 is connected with the base 1. The connection between the abutting plate 7 and the base 1 is preferably detachable. The elastic member 5 is a spring. The spring is sleeved on the handle 3. The two ends of the spring are respectively abutted with the guide column 6 and the abutting plate 7. The spring can be easily detached after long-term use.

[0031] The working principle of the circular part appearance detection auxiliary device is as follows:

[0032] Figure 2 As shown in Figure 3 , the handle 3 is first separated from the fixed column 2. The separation distance is greater than the thickness of the part, so that enough space is left to place the part. The part is placed vertically between the handle 3 and the fixed column 2. Then the fixed column 2 is connected with the handle 3. As shown in , the abutting piece 4 and the fixed column 2 are respectively abutted on both sides of the part to clamp and fix the part. The clamping of the part can be quickly realized. At this time, the fixed column 2, the part and the handle 3 are coaxial. At the same time, the distance between the handle 3 axis and the base 1 is greater than the radius of the part. When the handle 2 and the fixed column 3 clamp and fix the circular part, the bottom of the circular part is suspended, that is, it does not contact the base 1, so as to avoid friction between the base 1 and the circular part during rotation, further avoiding affecting the appearance of the circular part. After clamping is completed, the handle 3 is rotated. The handle 3 drives the abutting piece 4 and the fixed column 2 to rotate, and further drives the part to rotate, which is convenient for detecting the entire appearance of the part and does not easily affect the size precision of the part.
