[0034] Working principle: During assembly and use, based on the processing requirements and corresponding size specifications of the plate-shaped automotive parts, the side of the lower tray 210 is laterally adjusted with the cooperation of the extension beam 211 and the inner insert beam 212 to ensure support for the bottom of the parts. Then, the inner threaded pin 214 and the outer nut 215 are tightened for positioning. Similarly, with the cooperation of the extension arm 221 and the inner extension arm 222, the tray expands to a point of contact with the surface of the parts. This allows the lower pressure bar 224 and the inner pressure bar 226 to stably press against the parts with the cooperation of the rubber head 227, thus ensuring the lower tray 210 and the upper pressure plate 220... To facilitate the clamping of parts, the lower rotating shaft 230 and the upper stud 240 are assembled, and the bearing facilitates the rotation of the lower rotating shaft 230. The upper stud 240, with the cooperation of the bearing, will not hinder the passive rotation of the upper pressure plate 220 under the squeezing and clamping of the lower tray 210 and the parts. With the cooperation of the transmission turntable 261, the rotation is made more convenient. During grinding, the upper slide 310 moves the motor 330 and the grinding head 340 horizontally with the cooperation of the upper slide rail 301. Then the telescopic cylinder 320 allows the grinding head 340 to easily approach the periphery of the parts for grinding operations. The operation ends here.
