[0001] The invention relates to the technical field of door panel opening, in particular to opening equipment for anti-theft door shells and a production process thereof. Background Art

[0002] The main material of anti-theft doors is generally metal. When processing metal anti-theft doors, the door body is often positioned by a positioning device as described in Publication No. CN118616982A, and then the front and rear plates are connected to the frame by welding. However, welding will cause displacement deviation. Therefore, when processing some holes that penetrate the front and rear plates with high precision, drilling is often performed after welding is completed.

[0003] However, when the hole opening operation is carried out on the security door after welding is completed, there is no support under the upper plate. When the hole opener moves downward to open the hole, the cutting force of the hole opener is insufficient and the pressure of the hole opener on the upper plate surface is too great, causing the upper plate to be concave near the hole opening position. At the same time, the temperature of the hole opener will rise sharply, resulting in the unqualified quality of the security door. Summary of the invention

[0025] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments: Refer to Figure 1-Figure 7 , a hole-opening device for the outer shell of an anti-theft door, including a drilling unit 1, a detection unit, an adjusting device 3 and a central control unit. The drilling unit 1 is configured on a manipulator or a fixture. When it is configured on the manipulator, the manipulator moves the drilling unit 1 above the drilling position. When the drilling unit 1 is configured on the fixture, the anti-theft door is moved below the drilling unit 1 through a rotating device, and the drilling unit 1 performs drilling operations on the anti-theft door.

[0026] The drilling unit 1 includes a drill 11, a lifting device 12 and a drilling motor 13. The drill 11 is configured on the drilling motor 13. The rotation of the drilling motor 13 drives the drill 11 to rotate. At the same time, the drilling motor 13 is controlled by the central control unit. The central control unit can control the rotation speed of the drilling motor 13 and transmit the real-time rotation speed to the central control unit.

[0027] The lifting device 12 includes a lifting platform 121, a base plate 122 and a screw 123. The drilling motor 13 is arranged on the lifting platform 121. The lifting platform 121 is guided and slidably arranged on the base plate 122. The drilling unit 1 is fixedly arranged on the manipulator or the fixing part through the base plate 122. The screw 123 is rotatably arranged on the base frame 122. At the same time, a wire sleeve is arranged on the lifting platform 121, and the screw 123 is also arranged on the wire sleeve. Then the screw 123 rotates to drive the lifting platform 121 to move up and down, and then the drill 11 moves up and down. A servo motor is arranged on the screw. The servo motor is controlled by the central control unit, and then the central control unit controls the drill 11 to move up and down, and can control the speed of the up and down movement.

[0028] The adjusting device 3 includes a clamping frame 31, a connecting piece 32, a guide sleeve 33 and a temperature sensing installation unit 34. The connecting piece 32 is arranged on the bottom surface of the base plate 122. The connecting pieces 32 are arranged on the left and right sides of the bottom surface of the base plate 122. A guide rod 321 is arranged horizontally on the connecting piece 32. The guide rod 321 is connected to the connecting piece 32, and an electromagnetic component is arranged at the connection. There are two clamping pieces 31, and they are symmetrically limited and slidably arranged on the guide rod 321. A first elastic piece is sleeved on the guide rod 321. One end of the first elastic piece touches the limit piece at the outer end of the guide rod 321, and the other end touches the clamping frame 31. Under the action of the first elastic piece, the two clamping frames 31 are elastically pressed toward the middle and touch the electromagnetic component.

[0029] When the electromagnetic component is energized, the clamping frame 31 is pushed to move to both sides of the guide rod 321, thereby increasing the distance between the two clamping frames 31, and an arc groove is set in the middle position of the clamping frame 31. The two clamping frames 31 are clamped in the middle under the action of the first elastic member, thereby fixing the guide sleeve 33, and the guide sleeve 33 is used to guide the drill 11. There are differences in diameters of the holes on different anti-theft doors. Drills 11 of different calibers are required each time, and the guide sleeve 33 adapted to the drill 11 also needs to be replaced. The two sliding clamping frames 31 are used to quickly replace the guide sleeve 33. When the guide sleeve 33 needs to be replaced, it is only necessary to energize the electromagnetic component, and the guide sleeve 33 can be taken out upwards. When the new guide sleeve 33 is placed on the arc groove of the clamping frame 31, the electromagnetic component is de-energized, and the new guide sleeve 33 can be clamped under the action of the first elastic member, thereby quickly completing the replacement of the guide sleeve 33.

[0030] Infrared rangefinders for detecting distance are disposed on the bottom surfaces of the two clamping frames 31, and the infrared rangefinders are located next to the arc grooves. When the drill 11 is drilling holes in the board surface, the position detected by the infrared rangefinders is next to the hole positions.

[0031] After the drilling unit 1 is located above the drilling position of the anti-theft door, the hole turner 11 starts to rotate, and at this time the bottom surface of the clamping frame 31 is not in contact with the board surface. At this time, the infrared rangefinder obtains an initial distance value. At the same time, the drilling unit 1 can be moved above the hole position by the manipulator. The manipulator continues to control the drilling unit 1 to move downward. At this time, the infrared rangefinder detects the distance to the board surface below in real time. After it drops to the set value, the manipulator is controlled to stop descending, and the drill 11 is controlled to start rotating.

[0032] When the drill 11 starts to descend to drill the upper plate of the anti-theft door, the infrared rangefinder monitors the up and down position of the plates around the drilling position. When the concave distance is greater than the set value, the drilling machine 21 has insufficient cutting force on the plate surface, resulting in the drill 21 not being able to keep up with the descending speed. If the concave distance is too large, the plates around the drilling position will not be able to be reset after the drilling is completed, causing the area around the drilling position to be concave, thereby affecting the quality of the anti-theft door. Therefore, when the infrared rangefinder detects that the distance is greater than the set value, the central control unit controls the electronic control motor 13 to increase the speed and slow down the descending speed of the lifting platform 121. When the distance parameter returns to the set value, the increase in the speed of the drilling motor 13 is stopped and maintained at the current speed. At the same time, the lifting platform 121 is controlled to maintain the current descending speed. At the same time, the central control unit records the current speed and descent speed, overwriting the previous records.

[0033] Before replacing the drill 11 or changing the type of security door, subsequent work will continue to use the data from this time, and the records will be updated in real time during subsequent hole-opening operations to adapt to the decrease in cutting force caused by wear of the drill 11, so that the drill 11 can work for a longer period of time while ensuring the drilling quality of the security door.

[0034] The temperature sensing mounting frame 34 includes a telescopic member 341 and a lifting member 342. The telescopic member 341 is arranged on the clamping frame 31. The temperature control detector is arranged below the lifting member 342. The guide sleeve 33 is provided with a through groove 331 for avoiding the temperature sensing mounting frame 34. The temperature control detector is an infrared temperature detector, which can monitor the temperature of the drill 11 without contact.

[0035] When the driller 11 is drilling a hole in the upper plate of the anti-theft door, the lifting member 342 is located in the through groove of the guide sleeve 33, that is, located on the side of the driller 11. Therefore, when the driller 11 is drilling a hole in the upper plate of the anti-theft door, the temperature control detector can detect the temperature of the driller 11 and transmit the data to the central control unit. When the temperature control detector detects that the temperature of the driller 11 is greater than the set value, the central control unit slows down the descending speed of the lifting platform 121.

[0036] After the driller 11 completes drilling the upper plate of the anti-theft door, it continues to move downward to drill the lower plate surface. At this time, the infrared rangefinder cannot detect the distance to the lower plate, so it no longer detects the distance to the lower plate. The temperature control detector extends into the drill hole of the upper plate through the temperature sensing mounting bracket 34 to continue to monitor the temperature of the driller 11.

[0037] The lower end of the drill 11 is a hole-opening member 111 with sharp teeth, and a rod body 112 with a smaller diameter than the hole-opening member 111 is arranged at the center of the upper end of the hole-opening member 111. After the drill 11 completes drilling the upper plate, it continues to descend. After descending a set distance, the telescopic member 341 extends out, driving the lifting member 342 to enter above the hole-opening member 111. The diameter of the rod body 112 is smaller than the diameter of the hole-opening member 111 to provide an avoidance space for the lifting member 342 to extend into.

[0038] The lifting member 342 includes a guide shell 3421, a guide body 3422 and a rotating block 3423. The guide body 3422 is slidingly arranged in the guide shell 3421. The rotating block 3423 is configured to limit rotation at the lower end of the guide body 3422. Two electromagnets with opposite magnetic poles are configured on the lower end surface of the guide body 3422. A magnetic pole piece is provided on the upper end surface of the rotating block 3423. The temperature control detector is configured on the rotating block 3423. The guide shell 3421 is connected to the guide body 3422 by an electric telescopic rod, thereby controlling the upward and downward telescopic movement of the guide body 3422.

[0039] In the initial state, the battery iron of the two electromagnets with the opposite magnetic pole to the magnetic pole piece is energized, thereby locking the rotating block 3423 on the guide body 3422. When the telescopic member 341 is extended and the guide body 3422 is extended downward into the drilled hole of the upper plate of the anti-theft door, the battery iron of the two electromagnets with the same magnetic pole as the magnetic pole piece is energized, thereby rotating the rotating block 3423 around the rotating axis and finally pressing against the limit member, thereby making the rotating block 3423 and the guide body 3422 form a certain angle, which is greater than 20 degrees and less than 70 degrees. At this time, the rotating block 3423 is located between the upper and lower plates of the anti-theft door, and the rotating block 3423 is in an inclined state, so that the temperature control detector arranged on the rotating block 3423 can detect the opening member 111, and then detect the temperature on the opening member 111, and perform temperature monitoring.

[0040] When a hole is drilled in the upper plate of the anti-theft door, the temperature sensing mounting frame 34 is located in the through groove of the guide sleeve 33 to avoid the hole-opening member 111 , and the temperature control detector is located on one side of the hole-opening member 111 to monitor the temperature of the hole-opening member 111 .

[0041] When the opening piece 111 completes drilling the upper plate and enters between the upper and lower plates, the telescopic piece 341 extends and the guide body 3422 extends downward, so that the rotating block 3423 is located between the upper and lower plates of the anti-theft door. At this time, the central control unit controls the battery iron with the same magnetic pole as the magnetic pole piece in the two electromagnets to be energized, so that the rotating block 3423 rotates and presses on the limit piece, so that the rotating block 3423 and the guide body 3422 are at a certain angle, so that the temperature control detector can detect the opening piece 111, and then detect the temperature on the opening piece 111, and perform temperature monitoring.

[0042] Its working principle or usage is as follows: After the drilling unit 1 is located above the drilling position of the anti-theft door, it stops moving, the infrared rangefinder obtains an initial distance value between it and the upper plate of the anti-theft door below, and the drilling unit 1 starts working.

[0043] The drill 11 descends to drill a hole in the upper plate of the anti-theft door, and the infrared rangefinder monitors the up and down position of the plates around the drilling position. When the recessed distance is greater than the set value, the electronic control motor 13 is controlled to increase the speed and slow down the descending speed of the lifting platform 121. When the distance parameter returns to the set value, the increase in the speed of the drilling motor 13 is stopped and maintained at the current speed. At the same time, the lifting platform 121 is controlled to maintain the current descending speed. At the same time, the central control unit records the current speed and descending speed, overwriting the previous records.

[0044] When a hole is drilled in the upper plate of the anti-theft door, the temperature sensing mounting frame 34 is located in the through groove of the guide sleeve 33, thereby avoiding the hole-opening part 111, and the guide body 3422 locks the rotating block 3423. The temperature control detector is located on one side of the hole-opening part 111, and the temperature control detector monitors the temperature of the hole-opening part 111.

[0045] When the opening piece 111 completes drilling the upper plate and enters between the upper and lower plates, the telescopic piece 341 extends and the guide body 3422 extends downward, so that the rotating block 3423 is located between the upper and lower plates of the anti-theft door. At this time, the central control unit controls the battery iron with the same magnetic pole as the magnetic pole piece in the two electromagnets to be energized, so that the rotating block 3423 rotates and presses on the limit piece, so that the rotating block 3423 and the guide body 3422 are at a certain angle, and the temperature control detector can detect the opening piece 111, and then detect the temperature on the opening piece 111, and start temperature monitoring again.

[0046] The temperature control detector detects the temperature of the opening 111 and transmits the real-time temperature data to the central control unit. When the temperature control detector detects that the temperature of the opening 111 is greater than the set value, the central control unit slows down the descent speed of the lifting platform 121. When the temperature returns to the temperature range, the lifting platform 121 returns to the previous descent speed. At the same time, the temperature control detector adjusts the descent speed of the lifting platform 121 in real time. Example 2

[0047] Compared with Example 1, the difference lies in the location of the infrared range finder, and the rest are the same. Figure 1-Figure 7 Specifically, the infrared rangefinder is configured on the rotating block 3423, and infrared rangefinders are provided on the lower end of the side and the bottom surface of the rotating block 3423.

[0048] When a hole is drilled in the upper plate of the anti-theft door, the infrared rangefinder located on the bottom surface of the rotating block 3423 works, and when the hole-drilling member 111 drills a hole in the lower plate of the anti-theft door, the rotating block 3423 extends from the hole of the upper plate to between the upper and lower plates of the anti-theft door and rotates a certain angle. At this time, the infrared rangefinder on the side of the rotating block 3423 is aligned with the plate surface around the hole position of the lower plate, and then the infrared rangefinder on the side of the rotating block 3423 starts to work and detects the plate surface around the hole position of the lower plate. Then, when holes are drilled in the upper and lower plates of the anti-theft door, the concave distance can be detected in real time, and the drilling unit 1 can be controlled and adjusted in real time to further ensure the quality of the hole drilling of the anti-theft door. Example 3

[0049] This embodiment makes the following further improvements on the basis of embodiment 1 or 2: Figure 1-Figure 7 A positioning groove 3424 is provided on the front end surface of the guide shell 3421, and a temperature sensing mounting frame 34 is provided on the left and right clamping frames 31. When the hole-opening member 111 enters between the upper and lower plates of the anti-theft door, the left and right telescopic members 341 extend out at the same time, and the positioning grooves 3424 on the left and right guide shells 3421 position the rod body 112 left and right, so that the rod body 112 will not shake when rotating, thereby making the hole-opening member 111 more stable when opening a hole in the lower plate of the anti-theft door.
