Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] See also Figure 1-8 One embodiment of the present invention is: a metal parts processing contour cutting device, including a processing table 1, and also including:

[0073] Two clamping mechanisms 2 are arranged on the top of the processing table 1 and are used to clamp the cylindrical parts;

[0074] An adjusting component 3 is disposed below the processing table 1 and is used to adjust the distance between the two clamping mechanisms 2;

[0075] The material pushing mechanism 4 is arranged inside the clamping mechanism 2 and is used to push out the cut cylindrical parts;

[0076] The side clamping mechanism 5 is arranged on the right side of the right clamping mechanism 2 and is used for laterally clamping the columnar parts;

[0077] Two cutting machines 6, respectively mounted on the inner sides of the two clamping assemblies 2, for simultaneously cutting cylindrical parts;

[0078] Wherein, the clamping mechanism 2 comprises:

[0079] A clamping box 21 is arranged on the top of the processing table 1;

[0080] Two clamping claws 24 are hinged to the upper and lower sides of the inner wall of the clamping box 21 and are used to clamp the cylindrical parts;

A cylinder 22 is installed on the back of the clamping box 21, and its output end is connected to one end of the cross push rod 25 to push the cross push rod 25 to move and clamp the columnar parts at three points.

[0082] One end of the two adjustment plates 23 is hinged to the inner wall of the clamping box 21, and the other two sides are movably connected to the clamping jaws 24 and the cross push rod 25 through limit columns, so as to pull the clamping jaws 24 to open.

[0083] The clamping mechanism 2 also includes:

[0084] A plurality of pulleys 26 are installed at both ends of the clamping jaw 24, and the top and bottom sides of the cross push rod 25 are inclined and fit with the pulley 26, and the pulley 26 rolls on the inclined part of the cross push rod 25 and the outer wall of the columnar component;

[0086] Working principle: Place the metal parts that need to be contoured directly on the clamping mechanism 2, extend the cylinder, and push the cross push rod 25 to move. When it drives the pulley 27 to approach the cylindrical part, the wedge-shaped surface on its top squeezes the clamping jaw 24 to deflect around the hinge point, so that the other two sides of the clamping jaw 24 push the pulley 1 26 to approach the cylindrical part, thereby achieving three-point clamping of the cylindrical part, and it can be rotated during cutting. When releasing the clamp, it only needs to contract the cylinder to drive the cross push rod 25 to move in the opposite direction, and pull the clamping jaw connected to the outer wall through the adjustment plate 23, so that the clamping jaw 24 can be opened to achieve opening and closing, and the cylindrical part can be released.

7. A metal parts processing contour cutting device according to claim 6, characterized in that: The rotary disk (54) is provided with a blanking assembly (57) for pushing out the discarded cylindrical parts after cutting; the blanking assembly (57) comprises: A hemisphere (571) movably connected to a T-shaped through hole provided on the rotating disk (54); A spring (572) is connected in the T-shaped through hole and connected to the hemisphere (571); A feeding rod (573) movably connected to the T-shaped through hole; A fixed cylinder (574) is connected to the inner wall of the rotating disk (54), and the unloading rod (573) slides on the inner wall of the fixed cylinder (574); A return spring (575) is arranged on the inner wall of the fixing tube (574) and is used to pull the unloading rod (573) away from the hemisphere (571); A blanking plate (576) is disposed on the inner wall of the rotating disk (54) and connected to the adjusting rod (564) via a connecting rod; The unloading rod (573) is provided with a wedge-shaped groove, and one side of the unloading plate (576) is arranged to be inclined and fit together, so as to push the unloading rod (573) to move.

8. A metal parts processing contour cutting method, using the metal parts processing contour cutting device as claimed in claim 7 to process metal parts, characterized in that: The following steps are involved: S1: placing a cylindrical component on a processing table (1) and fixing the cylindrical component by two clamping mechanisms (2); S2: After adjusting the distance between the two clamping mechanisms (2), the columnar component is laterally clamped and limited by the provided side clamping mechanism (5); S3: The cutting machine (6) is started to operate, and the motor (55) is started to drive the cylindrical component fixed by the side clamping mechanism (5) to rotate. According to the diameter of the cylindrical component to be cut, the cross push rod (25) is pushed to move, thereby realizing the rotation cutting of the required contour of the cylindrical component; S4: The cylinder (22) is operated in the reverse direction to pull the cross push rod (25) to reset and reset the clamping jaws (24), thereby achieving contact and fixation of the cylindrical component, and pushing out the cut cylindrical component through the pushing mechanism (4), while pushing the discarded cylindrical component after cutting away from the inner circle clamping component (56) through the unloading component (57).
