A positioning rod 206 is provided on the side of the drill rod 203. When the positioning rod 206 is located in the vertical cavity 224 and the sliding cavity 211, the drill rod 203 is in a retracted state; when it is located in the vertical cavity 224 and the locking cavity 212, the drill rod 203 is in an extended state.

[0022] In this embodiment: the multi-station mechanical processing punching machine is mainly divided into three parts: a surrounding mechanism 1 and a drilling mechanism 2. When the device is working, the mounting frame 123 can be stopped at any position through the control panel in the device. When the mounting frame 123 moves to the position at the same height as the horizontal groove 107, the steel plate 125 is placed on the limiting boss 124. Then the drive motor 116 is started again, and the first sliders 118 on both sides drive the steel plate 125 to move upward along the vertical outer groove 108, and the second slider 119 moves from the leftmost side to the middle of the horizontal outer groove 110. When the first slider 118 moves quickly to the top of the vertical outer groove 108, the drill rod 203 abuts against the steel plate 125 and drills it.

Under the action of the squeezing arm 219, the positioning rod 206 on the drill rod 203 enters the locking cavity 212 along the sliding cavity 211, and the drill rod 203 extends out of the outer shell 201. Since the rotating inner shell 202 also rotates relative to the outer shell 201, under the action of the vertical cavity 224, the positioning rod 206 on the replaced drill rod 203 is separated from the locking cavity 212. Under the action of the elastic member 210 , the rotating inner shell 202 also returns to its original position. At this time, the positioning rod 206 on the replaced drill rod 203 slides into the sliding cavity 211 , and the drill rod 203 also retracts into the outer shell 201 .

[0041] Working principle of the present invention: When the device is working, the installation frame 123 can be stopped at any position through the control panel in the device. When the installation frame 123 moves to the position at the same height as the horizontal groove 107, the steel plate 125 is placed on the limiting boss 124. Then the driving motor 116 is started again, and the first sliders 118 on both sides drive the steel plate 125 to move upward along the vertical outer groove 108, and the second slider 119 moves from the leftmost side to the middle of the horizontal outer groove 110. When the first slider 118 moves quickly to the top of the vertical outer groove 108, the drill rod 203 abuts against the steel plate 125 and drills it. When the first slider 118 moves to the top of the vertical outer groove 108, the drilling is completed. When the first slider 118 moves from the top to the middle of the vertical outer groove 108, the second slider 119 moves from the middle of the horizontal outer groove 110 to the right. At this time, the brush 128 will clean the bottom of the steel plate 125, and the debris left on the bottom of the steel plate 125 will fall into the collection bin 103 at the bottom, and at this time, under the action of the tooth plate 126 and the flip gear 127, the brush 128 will move horizontally and rotate. When the first slider 118 moves from the middle of the vertical outer groove 108 to the bottom, the second slider 119 will move from the rightmost side to the middle of the horizontal outer groove 110. At this time, the brush 128 will clean the top of the steel plate 125, and the debris left on the top of the steel plate 125 will fall into the collection bin 103 at the bottom, and at this time, under the action of the tooth plate 126 and the flip gear 127, the brush 128 will move horizontally and rotate. When the first slider 118 moves upward from the bottom of the vertical outer groove 108, the second slider 119 will move from the middle of the horizontal outer groove 110 to the left. When the first slider 118 moves to the middle, the punched steel plate 125 is taken out and replaced with a new steel plate 125. When a better drill rod 203 is needed, the drill change motor 214 is started. When the drill change gear 215 rotates, it drives the gear ring 218 to rotate relative to the top cover 216, and at this time, the squeezing arm 219 squeezes one group of squeezing parts 204. Under the action of the squeezing arm 219, the positioning rod 206 on the drill rod 203 enters the locking cavity 212 along the sliding cavity 211, and the drill rod 203 extends out of the outer shell 201. Since the rotating inner shell 202 also rotates relative to the outer shell 201, under the action of the vertical cavity 224, the positioning rod 206 on the replaced drill rod 203 is separated from the locking cavity 212. Under the action of the elastic member 210 , the rotating inner shell 202 also returns to its original position.

When the first slider 118 moves upward from the middle of the vertical groove 106, it will drive the steel plate 125 to move toward the drilling mechanism 2. At this time, the second slider 119 moves from the leftmost side to the middle of the transverse groove 107. When the first slider 118 moves to the top of the vertical groove 106, the drilling is completed. When the first slider 118 moves from the topmost side to the middle of the vertical groove 106, the second slider 119 moves from the middle of the transverse groove 107 to the right side. At this time, the brush 128 cleans the bottom of the steel plate 125, and the debris left at the bottom of the steel plate 125 after drilling falls into the collection bin 103 at the bottom. When the first slider 118 moves from the middle of the vertical groove 106 to the bottom, the second slider 119 moves from the rightmost side of the transverse groove 107 to the middle. At this time, the brush 128 cleans the top of the steel plate 125, and the debris left on the top of the steel plate 125 after drilling falls into the collection bin 103 at the bottom. This design greatly reduces the time cost and labor cost of the multi-station machining punch. The present invention can freely adjust the specifications of the drill rod 203 according to demand through the drilling mechanism 2, wherein the extrusion arm 219 can be driven to press the top of the extrusion part 204 downward in turn under the cooperation of the drill gear 215 and the gear ring 218. Under the action of the extrusion arm 219, the positioning rod 206 on the side of the drill rod 203 will enter the locking cavity 212 from the sliding cavity 211 and extend out of the housing 201. The last group of drill rods 203 extending out of the housing 201 return from the locking cavity 212 to the sliding cavity 211. At this time, the drill rods 203 are retracted into the housing 201. This design improves the practicality and freedom of the multi-station machining punching machine.
