[0024] In this embodiment, the auxiliary clamp 22 is flexibly adjusted to adapt to workpieces of different shapes and sizes, effectively solving the problem of loosening or offsetting of the workpiece during processing, thereby improving the processing accuracy. The auxiliary discharging mechanism 2 slides on the fixed frame 1 to move the processed workpiece to the surface of the discharging conveyor belt, and discharges the workpiece through the discharging conveyor belt, which is convenient for adjusting the discharging direction and position, avoiding the damage of the workpiece due to the downward-tilted discharging method, and is disassembled and assembled through the connecting plate 11, which improves the flexibility of the auxiliary device, reduces maintenance costs, automates clamping and discharging, reduces manual intervention, improves production efficiency, realizes effective separation of waste chips and finished products, avoids contamination and damage of finished products, reduces the labor intensity of operators, and improves the working environment.

[0025] In this embodiment, the surface of the auxiliary support plate 21 is sequentially installed with a motor seat 25, a movable side plate 26, a fixed side plate 27 and a fixed splint 28. The fixed side plate 27 is arranged on one side of the conveyor belt 23, and the fixed splint 28 is arranged on the other side of the conveyor belt 23. A non-slip pad is provided on one side of the fixed splint 28. The surface of the motor seat 25 is fixedly connected to the driving motor 29, and one side of the driving motor 29 is fixedly connected to the threaded rod 291. The threaded rod 291 passes through the motor seat 25 and engages with the movable side plate 26. A threaded groove compatible with the threaded rod 291 is provided on the surface of the movable side plate 26. A translation guide block 261 is installed at the lower end of the movable side plate 26. One side of the translation guide block 261 is fixedly connected to the telescopic rod 262. The surface of the auxiliary support plate 21 is provided with a translation groove for the movement of the translation guide block 261.

[0026] In this embodiment, the threaded rod 291 is driven to rotate by the driving motor 29, thereby realizing the translation of the movable side plate 26. The movable side plate 26, the fixed side plate 27 and the fixed clamp 28 cooperate with the auxiliary clamp 22 to realize the clamping of the workpiece, and cooperate with the transmission of the conveyor belt 23 to realize the loading and unloading of the workpiece. The overall structure is compact and small in size, which is suitable for milling machines of various models and sizes, facilitates the precision processing of the milling machine, and thus improves the production quality of the milling machine.

[0027] In this embodiment, the auxiliary clamp 22 includes a pin seat 221, a movable clamp 222, a movable plate 223 and a clamping rod 224. One side of the pin seat 221 is installed on one side of the movable side plate 26 by a bolt. The pin seat 221 is movably connected to the center of the movable clamp 222. The two sides of the movable clamp 222 are rotatably connected to the movable plate 223 through pins. Clamping rods 224 are symmetrically arranged on both sides of the movable plate 223.

[0028] In this embodiment, the movable side plate 26 is translated, the clamping rod 224 slides in the guide hole, and the spring 225 is compressed. The clamping rod 224 cooperates with the fixed clamping plate 28 to clamp the workpiece, and under the action of the spring 225, the clamping rod 224 maintains a certain tension, and as the movable side plate 26 advances, it further drives other clamping rods 224 to clamp the workpiece. At the same time, the buffering effect of the spring 225 reduces the impact and damage to the workpiece during the clamping process, which helps to protect the surface quality of the workpiece. Furthermore, the workpiece is firmly clamped in the auxiliary clamp 22, and various workpieces can be easily clamped. It is suitable for workpieces of different shapes and sizes, and expands the scope of application.

[0029] Working principle: The driving motor 29 is started to drive the threaded rod 291 to rotate, so that the movable side plate 26 moves in the horizontal direction. As the movable side plate 26 approaches, the clamping rod 224 contacts the workpiece in turn and compresses the spring 225. The compression of the spring 225 increases the clamping force of the clamping rod 224 on the workpiece. At the same time, the fixed clamp 28 cooperates with the anti-slip pad to play a clamping role, and together they firmly clamp the workpiece in the auxiliary fixture 22, thereby realizing the processing of the workpiece. Through the sliding of the auxiliary discharging mechanism 2 on the fixed frame 1, the processed workpiece is moved to the surface of the discharging conveyor belt and discharged through the discharging conveyor belt.
