For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0019] As shown in Figures 1-4 The utility model provides a kind of multi-workpiece drilling machine, including workbench 1, the top of workbench 1 is equipped with workpiece fixed platform 2, the top of workbench 1 and located workpiece fixed platform 2 rear is provided with drill rig rack 4, the top of drill rig rack 4 is provided with multiple lifting frames 6 by hinged frame, the top of multiple lifting frames 6 is fixedly installed with drill rig body 5, the inside of drill rig rack 4 is provided with multiple pneumatic cylinders 7 by hinged frame, the bottom of multiple lifting frames 6 is all provided with two sliding slots 8, the bottom of multiple sliding slots 8 is all slidingly installed with sliding block 9, the bottom of multiple sliding blocks 9 is all connected with one end of multiple pneumatic cylinders 7, the inside of workpiece fixed platform 2 is provided with multiple clamping structures 3 for fixing the workpiece required to be processed.

[0020] Among them, drill rig body 5 is automatic telescopic drill, it is convenient to drill the workpiece on clamping structure 3, multiple clamping structures 3 are located in front of multiple drill rig bodies 5.

[0021] Specifically, when the drilling machine needs to be processed to drill the workpiece, the workpiece can be fixed on the multiple clamping structures 3 of the workpiece fixing table 2 first, and then the workpiece is processed by using the drill body 5 on the top of the drill rack 4. When the workpiece needs to be processed to cut an angle, the lifting frame 6 can be extruded by the air cylinder 7, so that the lifting frame 6 is inclined on the side close to the clamping structure 3 under the action of the sliding groove 8 and the sliding block 9, and then the drill body 5 on the top of the lifting frame 6 is inclined, thereby completing the processing effect of the inclined angle.

[0022] In an optional embodiment, the clamping structure 3 comprises a rotating handle 301 and a bidirectional threaded rod 304, the bidirectional threaded rod 304 is arranged inside the workpiece fixing table 2 through a bearing, and one end of the bidirectional threaded rod 304 also penetrates the front of the workpiece fixing table 2 and extends to the outside. The top of the workpiece fixing table 2 is provided with two let-out holes 302 for each group of clamping structures 3, and the top of each let-out hole 302 is provided with two clamping blocks 303. The outer surface of the bidirectional threaded rod 304 is sleeved with two transmission blocks 306. The bottom of each let-out hole 302 is provided with two moving strip blocks 307, and the two moving strip blocks 307 and the two clamping blocks 303 are connected through the two let-out holes 302.

The other end of each connecting rod 305 is connected with the bottom of each moving strip block 307 through a hinged ball.

Since the bidirectional threaded rod 304 is threadedly connected with the two transmission blocks 306, the two transmission blocks 306 move towards or away from each other, so that the two transmission blocks 306 pull the connecting rod 305. While the transmission block 306 pulls the connecting rod 305, it applies a pulling force to the two moving strip blocks 307 connected with the connecting rod 305, so that the two moving strip blocks 307 move towards or away from each other under the action of the two let-out holes 302, thereby achieving the effect of driving the two clamping blocks 303 on the top of the two moving strip blocks 307 to be fixed.
