[0047] For example, one side of the baffle 6 is fixedly provided with a metal rod, the metal rod is movably inserted into the hole formed on the first conveying belt 11 or the hole formed on the second conveying belt 41, the operator only needs to push or pull the metal rod to change the position of the baffle 6, to avoid the valve core from deviating after rolling on the first conveying belt 11 or the second conveying belt 41.

[0048] Optionally, strip-shaped protrusions are arranged on the belts of the first conveying belt 11 and the second conveying belt 41, the strip-shaped protrusions are used for abutting against the valve core, to avoid the valve core from rolling on the belts of the first conveying belt 11 and the second conveying belt 41 when the first conveying belt 11 and the second conveying belt 41 convey the valve core.

[0049] As shown in Figure 2 and Figure 6As shown, the rotary table 7 is arranged between the conveying assembly 2 and the drilling and milling assembly 3, and is used to support the valve core. The rotary table 7 drives the valve core to rotate by rotating, so as to change the machining position of the valve core. The rotary table 7 includes, but is not limited to, an RT 65-100-MS rotary table or an HRT-160 rotary table. The top of the rotary table 7 is provided with a groove for accommodating the valve core. The groove limits the vertical valve core sent by the second clamp 22 and rotates around the rotation axis of the groove, drives the valve core to rotate around the axis, changes the position of the valve core relative to the drilling and milling power head 33, changes the machining position of the valve core, realizes multi-directional machining of the valve core, and improves the problem that the existing valve core drilling process needs to be manually transferred between different drilling devices multiple times.

[0050] Optionally, referring to Figure 10 Further comprising a deburring assembly 9. The deburring assembly 9 includes a support frame 91, an electric clamp 92, and a hydraulic cylinder 93 provided with a cylindrical diamond abrasive head 94 at the output end. The support frame 91 is vertically arranged. The electric clamp 92 is fixedly connected with the support frame 91. The opening side of the electric clamp 92 faces the conveying assembly 2. The hydraulic cylinder 93 is vertically arranged. One end of the hydraulic cylinder 93 provided with the cylindrical diamond abrasive head 94 is arranged opposite to the electric clamp 92. When the electric clamp 92 clamps the valve core, the valve core is in a vertical state. The movable end of the hydraulic cylinder 93 is elongated to push the cylindrical diamond abrasive head 94 into the valve core. The hydraulic cylinder 93 drives the cylindrical diamond abrasive head 94 to polish the burrs protruding from the inner wall of the valve core by repeatedly elongating and contracting the movable end, so as to remove the burrs on the inner wall of the valve core. The problem that the existing valve core drilling process needs to be manually transferred between different drilling devices multiple times is improved.

[0051] Optionally, the hydraulic cylinder 93 provided with the cylindrical diamond abrasive head 94 at the output end can be replaced by a rotary motor provided with the cylindrical diamond abrasive head 94 at the output end, so as to further polish the burrs on the inner wall of the valve core by the rotation of the cylindrical diamond abrasive head 94. A linear guide rail fixedly connected with the electric clamp 92 can be arranged on the support frame, so as to drive the electric clamp 92 to move in the vertical direction, so that the electric clamp 92 can clamp different positions of the valve core.

[0052] Optionally, the top of the rotary table 7 can be provided with only the cylindrical diamond abrasive head 94. The cylindrical diamond abrasive head 94 can enter the valve core when the second clamp 22 lowers the valve core. The cylindrical diamond abrasive head 94 can limit the position of the valve core by abutting, so as to avoid the valve core from falling or tilting. When the second clamp 22 clamps the valve core, driving the rotary table 7 to rotate can drive the cylindrical diamond abrasive head 94 to rotate, so as to polish the burrs protruding from the inner wall of the valve core. When the second clamp 22 releases the valve core, driving the rotary table 7 to rotate can drive the cylindrical diamond abrasive head 94 to rotate and drive the valve core to rotate, so as to finally change the machining position of the valve core.
