[0027] 1. The present invention provides a part leveling assembly on the inner side of the cutting bottom groove. The part leveling assembly starts corresponding work according to the detection result of the part monitoring device. When the plastic part is cylindrical, the lifting column works to push the leveling seat so that the leveling frame is higher than the cutting die seat. The steering motor drives the leveling frame to rotate so that the cylindrical docking groove is close to one side of the cutting die seat.

[0028] 2. The present invention is provided with a cylindrical parts pressing assembly under the support frame. The parts conveying roller frame driving mechanism drives the roller to rotate to convey the plastic parts. The parts monitoring device detects the type of conveyed parts and drives the corresponding pressing hand lever to work according to the type of cutting parts. When the part is cylindrical, the pressing hand lever works to push the limit arc frame to move downward. The limit arc frame cooperates with the adjustment arc frame to press and limit the cylindrical plastic part. When the part is plate-shaped, the pressing hand lever works to push the plate-shaped pressure seat to move downward to press and limit the part. The pressing piece is adaptively adjusted according to the different types of parts. The stability of the parts avoids the shaking of the plastic parts during the cutting process, and ensures the stability of the plastic parts during the cutting process.

[0029] 3. The present invention installs a support frame at the output end of the guide rail. The operation of the guide rail drives the support frame and the cutting tool holder to adjust their positions in the horizontal direction. The displacement measuring instrument monitors the horizontal distance between the guide rail and the support frame. When the preset part cutting distance is reached, the guide rail stops working, the cutting head rotates at high speed, and the cutting cylinder drives the cutting head to move downward to cut the plastic parts. The precise adjustment of the use position of the cutting tool holder improves the cutting accuracy of automotive plastic parts, meets the cutting requirements of plastic parts of different specifications, expands the application range of the cutting device, and further improves the cutting production quality of plastic parts.

[0030] 4. The present invention provides a supporting and pushing assembly on the inner side of the feed trough. After the plastic parts are cut, the pushing hand rod drives the micro-support head to move upward to support the bottom of the cut plastic parts. The steering motor rotates to release the limit of the cylindrical docking groove on the front end of the plastic parts. The feed hand rod pushes the pushing frame to slide on the inner side of the feed trough. The cut plastic parts are moved to the rubber conveyor belt for transportation and unloading.

When the diameter of the cylindrical plastic part is larger than the standard cutting processing standard, the expansion hand lever 47 works to push the adjustment arc frame 45, changing the horizontal distance between the adjustment arc frame 45 and the limit arc frame 7 to adjust the pressing range of the cylindrical plastic part.

[0074] The cutting head 35 rotates at high speed, and the cutting cylinder 34 drives the cutting head 35 to move downward to cut the plastic parts. After cutting is completed, the pushing handle 26 drives the micro-support head 27 to move upward to support the bottom of the cut plastic parts. The steering motor 41 rotates to release the limit of the cylindrical docking groove 43 on the front end of the plastic parts. The feeding handle 24 drives the pushing frame 25 to slide inside the feed groove 23. The cut plastic parts are moved to the rubber conveyor belt 12 for transportation and unloading.
