A connecting hole is opened at one end of the fixed shell 12, and the connecting hole is connected with the through hole. A protrusion is arranged on the outer wall of the connecting hole.

[0023] Specifically, when the interior of the head needs to be processed, the tail 11 is driven to flip through an external flipping device, thereby driving the frame 1 and the head to flip.

[0024] Furthermore, the clamping mechanism 2 is provided with two groups, and the two groups of clamping mechanisms 2 are symmetrically distributed, and are used to fix the head. A single group of the clamping mechanism 2 includes: A base plate 21, one end of which is provided with an expansion frame 22; A push rod 23 is installed at one end of the expansion frame 22 and serves as a driving element of the clamping mechanism 2.

The single group of clamping mechanism 2 also includes: A guide rail 28 mounted on the base plate 21; A guide block 29 is slidably disposed on the guide rail 28, and the guide block 29 is installed at the bottom of the slide 27; The top of the guide block 29 is connected to the slide 27, and the bottom is slidably arranged with the guide rail 28 to limit the movement trajectory of the slide 27 to prevent the slide 27 from deviating from the movement; The expansion frame 22 is provided with a through hole, and the output end of the push rod 23 is used to move inside the through hole.

[0025] Specifically, the two sets of clamping mechanisms 2 are installed symmetrically, that is, when working, the movement directions of the two pressing blocks 2701 are opposite.

[0026] Furthermore, the adjusting mechanism 3 is provided between the frame 1 and the clamping mechanism 2 and is used to drive the clamping mechanism 2 to rotate, and includes: A motor 31, serving as a driving unit of the adjustment mechanism 3; Gear 32, mounted at the output end of motor 31; A gear ring 33 meshes with the gear 32, and an annular plate 34 is mounted on the gear ring 33, and the annular plate 34 is mounted on the bottom of the bottom plate 21; The inner ring hole on the annular plate 34 and the through hole are interconnected; The output end of the motor 31 passes through the frame 1, and the motor 31 is installed at the bottom of the frame 1 through a positioning plate; The bottom of the annular plate 34 is provided with an annular groove, which is rotatably arranged on the protrusion of the connecting hole; The cooperation between the protrusion at the connecting hole and the annular groove on the annular plate 34 limits the movement trajectory of the annular plate 34 .

[0027] Furthermore, the monitoring mechanism 4 is provided with two groups, which are symmetrically distributed on both ends of the annular plate 34, for monitoring the position of the end cap.

This pre-tightening force is very important for ensuring the tightness of the mechanical connection and reducing vibration and noise; When the annular plate 34 rotates to a certain position, the limiting block 73 is prevented from further rotation due to the action of the spring 75, thereby playing a limiting role; The spring 75 can absorb the impact energy from the outside to prevent the system from being damaged by sudden impact. It can also help to smooth the movement of the annular plate 34, especially in the starting and stopping stages.

When the end cap is placed on the support roller 52, the spring plate 6 contacts the outer wall of the end cap, thereby assisting in positioning the end cap. S2: After the end cap is placed, the industrial robot is reset, and then the push rod 23 drives the fixing plate 24 to move, the fixing plate 24 drives the support rod 26 to move, and the support rod 26 drives the connecting plate 25, and then drives the slide 27 to move under the limit of the guide block 29 and the guide rail 28, and the slide 27 drives the abutting block 2701 thereon to move, and the two sets of clamping mechanisms 2 move synchronously, so that the two abutting blocks 2701 move synchronously towards each other, and the end cap is tightened and fixed from the inside; S3: real-time monitoring of the clamping state of the end cap by monitoring camera 42; S4: During processing, the motor 31 drives the gear 32 to rotate, and the gear 32 drives the gear ring 33 meshing with it, and the gear ring 33 drives the annular plate 34 to rotate, and the annular plate 34 drives the clamping mechanism 2 thereon to rotate, and then drives the head to rotate, so as to perform all-round processing in real time.
