[0003] After searching, it was found that the current automated punching equipment, such as CN202011299450.7, is mainly positioned by a robotic arm, etc., and the punching device runs to feed the punching amount to punch holes, and the overall control is controlled by a controller.

[0004] At present, the number of high-end medical equipment such as PET-CT, MRI, and Gamma Knife in my country is increasing year by year.

Working principle: When the latter part is being punched, i.e., the punching operation when the switching assembly 25 and the fine-adjusting transmission assembly 23 are working, the fine-adjusting linkage assembly 26 makes the fine-adjusting transmission assembly 23 and the switching assembly 25 combine with each other, and the combination process is as follows: the motor B261 rotates forward to drive the driving wheel 262 to rotate, the driving wheel 262 drives the driven wheel 263 to rotate, and the driven wheel 263 rotates to drive the sleeve 264 to rotate in the circular hole of the rotating shaft 236. Because the limit block C266 is square and is set inside the square limit groove and slides back and forth, the sleeve 264 drives the screw 265 to move backward, so that the friction block A267 moves backward and fits closely with the friction block B268, and then the rotating shaft 236 is connected with the synchronous shaft 251, and then the motor B261 stops. The rotating shaft 236 rotates synchronously with the synchronous shaft 251. Because the self-locking characteristics of the worm 232 and the worm wheel 235 enable the transmission tube 211 to maintain a height, and then the drilling head 4 maintains a height. At this time, the clamping block 246 on the right side is engaged with the middle through hole of the transmission tube 211 , and the clamping block 246 on the left side is engaged with the clamping groove B of the synchronous sleeve 231 .The adjustment process of the block 246 is as follows: the electric telescopic rod A247 on the bracket 2411 extends out to push the push plate 248 forward to push the block 245 into the transmission tube 211 part, and the block 245 drives the connecting plate 243 to move forward, so that the block 246 on the right is separated from the slot A of the gear A222. At this time, the block 245 drives the electric telescopic rod B249 to slide forward in the assembly slot 2415 of the bracket 2411 through the slide seat 2412, and then the electric telescopic rod B249 runs to push the block 245 to the left, thereby driving the connecting plate 243 to the left, and the block 246 on the left moves correspondingly. The through hole on the left and the block 246 on the right move to correspond to the through hole in the middle, and then the reset spring 244 of the electric telescopic rod A247 pushes the connecting plate 243 to reset backward, and the block 246 on the left is inserted into the slot B of the synchronous sleeve 231. At this time, the transmission tube 211 does not drive the gear A222 to rotate, and the motor A134 can be reversed appropriately so that the block 246 on the left can be quickly inserted into the slot B of the synchronous sleeve 231, and then the motor A134 can continue to rotate forward, and through the synchronous sleeve 231, the worm 232 and the worm wheel 235, the gear B252 and the rack B254, the drilling head 4 is fed.

[0031] The pressing block 245 and the connecting plate 243 are pressed and slid on the limiting rod 242 to limit the connecting plate 243 and the pressing block 245, and when the pressing block 245 moves left and right, the limiting rod 242 drives the slider 241 to slide in the displacement slot A. When the drilling head 4 continues to feed, the motor A134 drives the transmission tube 211 to rotate, and at this time, the synchronous sleeve 231 is driven to rotate through the block 246 on the left, and the synchronous sleeve 231 drives the worm 232 to rotate on the assembly frame 233, and the limiting slider A234 slides in the slide slot A to limit the assembly frame 233, maintaining the stability of the movement of the synchronous sleeve 231, and the rotation of the worm 232 drives the worm wheel 235 to rotate, and the worm wheel 235 drives the rotating shaft 236 to rotate on the assembly frame 233, and the rotating shaft 236 rotates through the friction block A267 to drive the friction block B268 to rotate and then drive the synchronous shaft 25 1 rotates, the synchronous shaft 251 rotates to drive the gear B252 to rotate downward on the rack B254, and the gear B252 moves on the rack B254 so that the gear B252 drives the limit block B253 to slide up and down in the slide groove B. The worm 232 rotates one circle to drive the worm wheel 235 to rotate one tooth, thereby driving the gear B252 to move more finely on the rack B254. At this time, the gear B252 drives the drilling head 4 downward through the assembly frame 233, and the feeding operation of the latter part of the drilling is more refined, thereby improving the drilling accuracy, improving the effect of the device for automatic drilling, and improving the quality of drilling.

[0032] When the device is in use, the robot arm 3 controls the position of the housing mechanism 1 and further controls the position of the drilling head 4 for positioning.

[0033] When the drilling operation is performed, when the front part of the workpiece is drilled, that is, the drilling operation when the coarse adjustment component 22 is working, the fine adjustment linkage component 26 makes the fine adjustment transmission component 23 and the switching component 25 disengage from each other. The motor A134 drives the turning handle 213 to rotate, and the turning handle 213 drives the transmission tube 211 to rotate through the output rod 212. At this time, the block 246 on the right side is engaged with the card slot A in the gear A222. The transmission tube 211 rotates through the block 246 to drive the gear A222 to rotate on the rack A223, thereby causing the transmission tube 211 to move downward, the transmission tube 211 slides in the lifting groove A111, and the output rod 212 slides in the lifting groove B121. At the same time, the motor A134 also moves downward, and the motor A134 drives the slide bar 132 to slide in the limit seat 131 through the connecting frame 133, which is used to synchronize the movement of the transmission tube 211. The assembly frame 233 drives the drilling head 4 to move downward to perform the first part of the drilling operation.

[0034] Because the block 246 on the right is engaged with the slot A in the gear A222, the motor A134 rotates forward, and the gear A222 rotates downward and moves downward along the rack A223, driving the entire punching lifting mechanism 2 to move downward to perform the punching operation. When the motor rotates reversely, the gear A222 drives the entire punching lifting mechanism 2 to move upward and return to the original position. The synchronous sleeve 231 will not rotate with the transmission tube 211, and the worm 232 and the worm wheel 235 will not rotate. The gear B252 rotates with the up and down movement speed of the gear A.

[0035] When the fine-adjustment linkage assembly 26 causes the fine-adjustment transmission assembly 23 and the switching assembly 25 to be disengaged from each other, the disengagement process is as follows: the motor B261 reverses to drive the driving wheel 262, the driven wheel 263, and the sleeve 264 to reverse, the screw 265, the limit block C266, and the friction block A267 move forward, and the friction block A267 and the friction block B268 are disengaged from each other, so that the rotating shaft 236 and the synchronous shaft 251 are not connected and will not move synchronously. Then the motor B261 stops.

[0036] When the latter part of the drilling is in progress, i.e., the drilling operation when the switching assembly 25 and the fine-adjusting transmission assembly 23 are working, the fine-adjusting linkage assembly 26 makes the fine-adjusting transmission assembly 23 and the switching assembly 25 combine with each other. The combination process is as follows: the motor B261 rotates forward to drive the driving wheel 262 to rotate, the driving wheel 262 drives the driven wheel 263 to rotate, and the driven wheel 263 rotates to drive the sleeve 264 to rotate in the circular hole of the rotating shaft 236. Because the limit block C266 is square and is set inside the square limit groove and slides back and forth, the sleeve 264 drives the screw 265 to move backward, so that the friction block A267 moves backward and fits tightly with the friction block B268, and then the rotating shaft 236 is connected to the synchronous shaft 251. Then the motor B261 stops. As mentioned above, the rotating shaft 236 rotates synchronously with the synchronous shaft 251. Because the self-locking characteristics of the worm 232 and the worm wheel 235 enable the transmission tube 211 to maintain a height, and then the drilling head 4 to maintain a height.

[0037] At this time, the block 246 on the right side is engaged with the middle through hole of the transmission tube 211, and the block 246 on the left side is engaged with the slot B of the synchronous sleeve 231. The adjustment process of the block 246 is as follows: the electric telescopic rod A247 on the bracket 2411 runs and extends to push the push plate 248 to push the push block 245 forward to enter the transmission tube 211 part, and the push block 245 drives the connecting plate 243 to move forward, so that the block 246 on the right side is separated from the slot A in the gear A222. At this time, the push block 245 drives the electric telescopic rod B249 to slide forward in the assembly slot 2415 of the bracket 2411 through the slide seat 2412, and then the electric telescopic rod B249 runs to push the push plate 248 to push the push plate 248 forward to enter the transmission tube 211 part. The block 245 moves to the left, thereby driving the connecting plate 243 to the left. The block 246 on the left moves to correspond to the through hole on the left, and the block 246 on the right moves to correspond to the through hole in the middle. Then the reset spring 244 of the electric telescopic rod A247 pushes the connecting plate 243 to reset backward, and the block 246 on the left is inserted into the slot B of the synchronous sleeve 231. At this time, the transmission tube 211 does not drive the gear A222 to rotate. The motor A134 can be reversed appropriately so that the block 246 on the left can be quickly inserted into the slot B of the synchronous sleeve 231. Then the motor A134 can continue to rotate forward, and the drilling head 4 is fed through the synchronous sleeve 231, the worm 232 and the worm wheel 235, the gear B252 and the rack B254. At this time, the block 246 on the right is separated from the gear A222, and the gear A222 rotates according to the lifting speed of the gear B252, and the gear A222 will not rotate with the transmission tube 211.

[0038] As described above, the pressing block 245 and the connecting plate 243 are pressed and slid on the limiting rod 242 to limit the connecting plate 243 and the pressing block 245 , and when the pressing block 245 moves left and right, the slider 241 is driven to slide in the displacement groove A through the limiting rod 242 .

[0039] When the drilling head 4 continues to feed, the motor A134 drives the transmission tube 211 to rotate. At this time, the synchronous sleeve 231 is driven to rotate through the block 246 on the left side. The synchronous sleeve 231 drives the worm 232 to rotate on the assembly frame 233. The limit slider A234 slides in the slide groove A to limit the assembly frame 233 to maintain the stability of the movement of the synchronous sleeve 231. The rotation of the worm 232 drives the worm wheel 235 to rotate. The worm wheel 235 drives the rotating shaft 236 to rotate on the assembly frame 233. The rotation of the rotating shaft 236 drives the friction block B268 to rotate through the friction block A267 and then drives the synchronous shaft 251 Rotate, the synchronous shaft 251 rotates and drives the gear B252 to rotate downward on the rack B254. The movement of the gear B252 on the rack B254 makes the gear B252 drive the limit block B253 to slide up and down in the slide groove B. The worm 232 rotates one circle and drives the worm wheel 235 to rotate one tooth, thereby driving the gear B252 on the rack B254 to move more precisely. At this time, the gear B252 drives the drilling head 4 downward through the assembly frame 233, and the feeding operation of the latter part of the drilling is more precise, thereby improving the drilling accuracy, improving the effect of the device for automatic drilling, and improving the quality of drilling.

[0040] It should be noted that when the device is in use, it is controlled as a whole by an external controller, and a sensor can be adapted to detect whether the card slots A and B are correctly engaged with the corresponding card blocks 246. The sensor can be a photoelectric sensor, and motor A134 and motor B261 are both servo motors.

[0041] The holes punched by the device have better punching effect for precision production and drilling of composite materials. When resetting, the motor A134 first reverses partly to lift part of the drilling head 4, and the fine-adjustment component 24 is reset to make the block 246 on the right engage with the slot A of the gear A222, and then the fine-adjustment linkage component 26 is reset to separate the friction block A267 from the friction block B268. When the friction block A267 and the friction block B268 are separated, the gear B252 moves on the rack B254, and the synchronous shaft 251 drives the friction block B268 to move through the limit tube 269, thereby driving the rotating shaft 236 to move synchronously.
