[0022] Such as Figures 1 to 3As shown in the figure, a flexible automatic hole-making device for structural parts includes a machine body 100. A workbench 110 is fixedly connected to the top wall of the machine body 100. On the upper side wall of the workbench 110, a fixed seat 120 and a fixed plate 130 are fixedly connected to both sides respectively. A plurality of cavities 140 are arranged in the fixed seat 120 in an equidistant array. A piston 150 is arranged in the cavity 140. One end of the piston 150 close to the fixed plate 130 is fixedly connected to a push rod 160. The other end of the push rod 160 slides through the fixed plate 130 and is fixedly connected to a clamping plate 170. A pressure sensor 180 is arranged at the center of the side wall of the clamping plate 170 away from the push rod 160. A robotic arm 200 is installed at the rear of the upper side wall of the workbench 110. A hole-making mechanism 300 is arranged at the head end of the robotic arm 200. A controller 111 is installed on one side wall of the workbench 110. A propulsion assembly 400 is also arranged on the fixed seat 120. A dust removal assembly 500 is arranged on the front side wall of the machine body 100. Under the action of the propulsion assembly 400, air will push the piston 150 to move, so that the push rod 160 pushes the clamping plate 170 to approach the structural part. If the side of the structural part is irregular, there will be a clamping plate 170 that contacts the side of the structural part first. The pressure sensor 180 on this clamping plate 170 can sense the contact between the clamping plate 170 and the structural part. After the controller 111 receives the electrical signal transmitted by the pressure sensor 180, it will control the solenoid valve 450 corresponding to this pressure sensor 180 to close, so that air no longer enters the cavity 140 corresponding to this pressure sensor 180, and the other clamping plates 170 continue to approach the structural part until all the clamping plates 170 all contact the side of the structural part. At this time, under the action of all the clamping plates 170, the structural part will be clamped and fixed. It can not only fix the structural parts with regular sides, but also fix the structural parts with irregular sides, and has higher applicability.

[0023] Specifically, as Figure 2 shown in the figure, a flexible automatic hole-making device for structural parts, the propulsion assembly 400 includes an air pump 410, a shunt pipe 420, an air delivery pipe 430, a connecting pipe 440 and a solenoid valve 450. An air pump 410 is installed on the upper side wall of the fixed seat 120. A shunt pipe 420 is arranged on the side wall of the fixed seat 120 away from the fixed plate 130. An air delivery pipe 430 is communicated between the exhaust end of the air pump 410 and the shunt pipe 420. The shunt pipe 420 is connected to the cavity 140 through a connecting pipe 440. A solenoid valve 450 is installed on the connecting pipe 440. The air pump 410 can transport air into the shunt pipe 420 through the air delivery pipe 430, and then enter a plurality of cavities 140 through the connecting pipe 440. The air will push the piston 150 to move, so that the push rod 160 pushes the clamping plate 170 to approach the structural part.

[0024] Specifically, as Figure 1As shown in the figure, a flexible automatic hole-making device for structural parts. The dust removal assembly 500 includes a box body 510, a negative pressure shell 520, a dust removal pipe 530, a filter screen plate 540 and a fan 550. The box body 510 is fixedly connected to the front side wall of the machine body 100. The negative pressure shell 520 is fixedly connected to the upper side wall of the fixing plate 130. The negative pressure shell 520 is communicated with the box body 510 through the dust removal pipe 530. A filter screen plate 540 is arranged in the box body 510. A fan 550 is fixedly connected to the front outer wall of the box body 510. The air inlet of the fan 550 is communicated with the box body 510 through an air pipe. During the hole-making process, under the action of the fan 550, the metal dust generated during hole-making will be sucked into the negative pressure shell 520, and then enter the box body 510 through the dust removal pipe 530. The metal dust will be filtered by the filter screen plate 540, and the dust-free air is discharged to the outside through the fan 550, effectively solving the problem that the metal dust is scattered on the workbench and is not convenient to clean, and can also prevent harm to the physical health of workers, making it safer and more practical.

[0025] Specifically, as Figure 4 shown, a flexible automatic hole-making device for structural parts. An installation opening 511 through which the filter screen plate 540 can pass is opened on the front side wall of the box body 510. Support grooves 512 are opened on both inner side walls of the box body 510. Slide rails 541 that are slidably matched with the support grooves 512 are fixedly connected to both side walls of the filter screen plate 540. The filter screen plate 540 is inserted into the box body 510 through the installation opening 511, and at the same time, the slide rails 541 will slide into the support grooves 512 to support and limit the filter screen plate 540.

[0026] Specifically, as Figure 2 shown, a flexible automatic hole-making device for structural parts. Guide rods are fixedly connected to one side wall of the clamping plate 170 close to the fixing plate 130 and are respectively located on the front and rear sides of the push rod 160. The other ends of the guide rods slide through the fixing plate 130 and extend between the fixing plate 130 and the fixed seat 120, making the movement of the clamping plate 170 more stable.

[0027] Specifically, as Figure 3 shown, a flexible automatic hole-making device for structural parts. A return spring 171 is fixedly connected between the clamping plate 170 and the fixing plate 130. The return spring 171 is sleeved on the outside of the push rod 160. When the positioning of the structural part is released and the air is released, the clamping plate 170 will be pulled back by the return spring 171.

[0028] In the specific implementation of the present utility model, the structural member is placed on the workbench 110, and then the controller 111 starts two air pumps 410. The air pumps 410 transport air through the air delivery pipe 430 into the shunt pipe 420, and then enter into a plurality of cavities 140 through the connection pipe 440. The air will push the piston 150 to move, so that the push rod 160 pushes the clamping plate 170 to approach the structural member. If the side of the structural member is irregular, there will be a clamping plate 170 that contacts the side of the structural member first. The pressure sensor 180 on this clamping plate 170 can sense the contact between the clamping plate 170 and the structural member. After the controller 111 receives the electrical signal transmitted by the pressure sensor 180, it will control the solenoid valve 450 corresponding to this pressure sensor 180 to close, so that air no longer enters the cavity 140 corresponding to this pressure sensor 180, and the remaining clamping plates 170 continue to approach the structural member until all the clamping plates 170 all contact the side of the structural member. At this time, all the solenoid valves 450 are closed. Under the action of all the clamping plates 170, the structural member will be clamped and fixed. It can not only fix the structural member with regular sides, but also fix the structural member with irregular sides, and has higher applicability. Then the robotic arm 200 drives the hole-making mechanism 300 to make holes in the structural member. This is a mature existing technology and will not be elaborated too much here. During the hole-making process, under the action of the fan 550, the metal dust generated during hole-making will be sucked into the negative pressure shell 520, and then enter the box body 510 through the dust removal pipe 530. The metal dust will be filtered by the filter screen plate 540, and the dust-free air is discharged to the outside through the fan 550, effectively solving the problem that the metal dust is spread all over the workbench and is not convenient to clean, and can also prevent harm to the physical health of workers, and is safer and more practical.
