[0057] Specifically, the working principle of the numerical control lathe irregular shape workpiece plane machining tooling is as follows: in the tooling preparation stage, if the spacing of the flexible clamp 30 needs to be adjusted to adapt to different sizes of special-shaped workpieces, the servo motor 106 is started, the worm 105 sleeved on the output end of the servo motor 106 is engaged with the worm gear 104 sleeved on the center of the bidirectional screw rod 103, thereby driving the bidirectional screw rod 103 to rotate, the sliding blocks 107 threaded at both ends of the bidirectional screw rod 103 move in the through slot 102, the fixed frame 201 is driven by the moving frame 202 to slide on the slide rails 108 on the upper end of the base 101, thereby adjusting the spacing of the clamping seats 301 in the flexible clamp 30, and the irregular special-shaped workpieces are placed in the flexible clamp 30. Since one end of the telescopic positioning rod 302 is slidingly connected with the pneumatic locking sleeve 303 and is provided with a spring 305, the uneven surface of the special-shaped part will extrude the corresponding telescopic positioning rod 302, the spring 305 is compressed, and the telescopic positioning rod 302 adapts to the surface of the special-shaped part. When the telescopic positioning rod 302 is extruded to the appropriate position, the pneumatic locking sleeve 303 is connected with the external air source through the air pipe 304, the telescopic positioning rod 302 is locked by the pneumatic locking sleeve 303, the two clamping seats 301 relatively move, and the special-shaped part is firmly fixed. When the machining starts, the waste generated by part of the workpieces falls on the conveyor belt 401, and after the operator takes away the workpiece, the cleaning mechanism 20 starts to work. The double-shaft motor 210 is installed between a pair of retaining frames 211 at the top end inside the power box 203, the output end of the double-shaft motor 210 drives the rotating shaft 212 connected in transmission to rotate, one end of the rotating shaft 212 is connected with the center shaft of the gear 207 rotatingly connected with the power box 203 at both ends in the cavity 208 of the sliding plate 205, the gear 207 is engaged with the rack 209 installed at the bottom end of the cavity 208 of the sliding plate 205, so that the sliding plate 205 drives the push plate 206 to slide in the slide groove 204 on both sides of the power box 203. A plurality of slot holes 213 are formed in one side of the push plate 206 and are slidingly connected with the telescopic positioning rods 302 of the flexible clamp 30. During the sliding process of the push plate 206, the waste accumulated in the gap of the telescopic positioning rod 302 can be pushed out. The pushed-out waste and the waste falling on the conveyor belt 401 are transported along with the continuous operation of the conveyor belt 401 in the moving groove 109. When the waste is transported to the position of the inclined plate 402, the inclined plate 402 is adjacent to the bottom side of one end of the conveyor belt 401, serving as a scraper to scrape the waste on the conveyor belt 401, and the waste slides along the inclined plate 402 to the cleaning groove 403 formed in one end of the base 101 and communicating with the moving groove 109, facilitating the operator to collect and clean the machining waste, avoiding the interference of the waste with the machining process, and ensuring the cleanliness of the entire tooling working area.
