[0033] The mounting mechanism is located at the top of the corner mechanism and is used to clamp the workpiece synchronously from all four sides.

[0034] A fixed shaft 405 is rotatably mounted on the inner side of the rotating plate 404. The fixed shaft 405 is located inside the mounting mechanism. The rotating plate 404 is square. L-shaped rods 411 are mounted on the side of the rotating plate 404. Four L-shaped rods 411 are arranged in a ring around the rotating plate 404.

When the cylinder 412 is activated, the cylinder 412 drives the push rod 408 to move. The push rod 408 drives the sliding member 410 to move through the push block 409. When the sliding member 410 moves, it drives the rotating plate 404 to rotate through the L-shaped rod 411, so that the rotating plate 404 drives the other three L-shaped rods 411 to rotate, thereby driving the other three sliding members 410 connected to the L-shaped rods 411 to slide in the slide groove 403 through the sliding plate 413 and the connecting block 406. The four connecting blocks 406 drive the four angled clamping plates 407 to move synchronously to clamp the workpiece.

[0036] Example 2

[0037] like Figures 2-3 As shown, this utility model proposes a pneumatic chamfering machine. Compared with Embodiment 1, this embodiment details the structure of the cornering mechanism.

[0038] The cornering mechanism includes a track base 301, a turntable 302, a motor 304, a control lever 305, and a tilting component. The track base 301 is located on the side of the mounting frame 1. The turntable 302 is rotatably mounted on the track base 301. A rotating shaft 303 is located at the bottom of the turntable 302. The motor 304 is located at the bottom of the rotating shaft 303. The control lever 305 is located on the side of the motor 304. A foot switch 306 is located at the end of the control lever 305 away from the motor 304. The foot switch 306 is located on the outside of the track base 301. When it is necessary to rotate the workpiece, the foot switch 306 is stepped on. After the switch is turned on, the motor 304 is started through the control lever 305. The motor 304 drives the rotating shaft 303 to rotate, and the rotating shaft 303 drives the turntable 302 to rotate on the track base 301. The tilting component is located on the top of the turntable 302 and is used to tilt the workpiece. The tilting assembly includes a support platform 307, a connecting shaft 308, a connecting platform 313, and a positioning plate 309. The support platform 307 is located on top of the turntable 302, and there are two support platforms symmetrically arranged about the turntable. The connecting shaft 308 is rotatably mounted on top of the support platform 307, and the connecting platform 313 is located outside the connecting shaft 308. The positioning plate 309 is located on the side of the support platform 307, and the positioning plate 309 has multiple through holes arranged in a ring for positioning. Each through hole represents a tilt angle of the workpiece. A rotating rod is provided at the end of the connecting shaft 308. 310. A positioning rod 312 is slidably provided at the end of the rotating rod 310 away from the connecting shaft 308. A spring 311 is provided on the outside of the positioning rod 312. When it is necessary to tilt the workpiece, the positioning rod 312 is pulled out from the positioning plate 309. At this time, the positioning rod 312 can be rotated. The positioning rod 312 drives the connecting shaft 308 to rotate through the rotating rod 310. The connecting shaft 308 drives the workpiece to tilt through the connecting table 313. When it is tilted to a suitable processing position, the rotation of the positioning rod 312 is stopped, and the positioning rod 312 is locked in the through hole at that position, thereby fixing the position of the workpiece.

[0039] In summary, when using this utility model, the workpiece is placed on the mounting plate 401, and the cylinder 412 is started. The cylinder 412 drives the push rod 408 to move. The push rod 408 drives the sliding member 410 to move through the push block 409. When the sliding member 410 moves, it drives the rotating plate 404 to rotate through the L-shaped rod 411. This causes the rotating plate 404 to drive the other three L-shaped rods 411 to rotate, thereby causing the other three sliding members 410 connected to the L-shaped rods 411 to slide in the slide groove 403 through the sliding plate 413 and the connecting block 406. The four connecting blocks 406 drive the four corner clamps 407 to move synchronously to clamp the workpiece. Then, the chamfering machine body 2 is started, and the chamfering machine body 2 clamps the workpiece. When performing pneumatic chamfering and needing to change the chamfer position of the workpiece, step on the foot switch 306. After the switch is turned on, the control lever 305 drives the motor 304 to start. The motor 304 drives the rotating shaft 303 to rotate, and the rotating shaft 303 drives the turntable 302 to rotate on the track base 301, thereby causing the workpiece to rotate. Pull the positioning rod 312 out of the positioning plate 309. At this time, the positioning rod 312 can be rotated. The positioning rod 312 drives the connecting shaft 308 to rotate through the rotating rod 310. The connecting shaft 308 drives the workpiece to tilt through the connecting table 313. Tilt it to a suitable processing position, stop rotating the positioning rod 312, and lock the positioning rod 312 into the through hole at that position, thereby causing the workpiece to tilt.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
