Description

Technical Field

[0001] The present invention relates to the technical field of civil air defense doors, and more specifically, to a drilling and positioning device for civil air defense doors. Background Art

[0002] Civil defense doors, as an indispensable entrance and exit barrier for civil defense projects, are one of the key equipment for the government to organize public protection and implement rescue operations when responding to emergencies such as air raids and natural disasters. Its sturdiness and precise installation are crucial to improving the overall protection effectiveness.

[0003] In order to improve the drilling accuracy and efficiency during the installation of civil air defense doors, the civil air defense door drilling positioning device came into being. This innovative equipment integrates core components such as positioning tooling, high-precision drilling machine and precision guide rail mechanism to form an efficient and coordinated working system. Among them, the drilling machine is the core unit for performing drilling operations. Its operating end is accurately aligned with the civil air defense door body to ensure that each drilling can reach the predetermined position and achieve precise operation.

[0004] However, the current drilling machines on the market have functional limitations, especially when dealing with high-intensity, long-term drilling tasks, the challenges are particularly significant. Due to the huge heat generated by the high-speed friction between the drill bit and the surface of the civil air defense door, not only will the civil air defense door material face the risk of deformation due to changes in physical properties, but it will also directly cause the drill bit itself to drop in hardness and weaken in an overheated state, increasing the possibility of breakage or damage. In addition, the thermal expansion effect of the material in a high temperature environment will further aggravate the size and shape deviation of the drill bit, posing a serious threat to the processing accuracy and stability of the drill bit, making it difficult to ensure the high-precision requirements of the drilling operation. In view of this, we propose a drilling positioning device for civil air defense doors. Summary of the invention

[0027] Working principle: This embodiment provides a drilling and positioning device for civil air defense doors. When in use, the civil air defense door to be processed is installed above the chassis positioner 101, and the civil air defense door is fixed by the chassis positioner 101. Then, the positions of the bracket 102 and the driver 104 are adjusted accordingly, so that the punching mechanism 2 is located directly above the position where the civil air defense door needs to be punched. At this time, the punching mechanism 2 can be started and the civil air defense door can be drilled; When the drive shaft 201 is driven by the driver 104 and the bracket 102 to move downward, the drill bit 202 will contact the civil air defense door. At the same time, the protection component 207 will also be located above the civil air defense door. As the drill bit 202 continues to move downward, the protection component 207 will gradually move upward along the sealing component 206. At this time, the protection component 207 will squeeze its internal gas into the adsorption component 208, causing the adsorption component 208 to expand externally. At the same time, as the drill bit 202 rotates, the pressure component 209 will also extract the air below and discharge it upward to each other, thereby accelerating the air flow rate at the drilling position and the surface of the drill bit 202, so that a large amount of gas enters along the adsorption component 208, and pushes the recovery component 205 to move upward and then be discharged along the installation component 204, and the waste chips during drilling will be retained between the installation component 204 and the recovery component 205; When the drill bit 202 is moved downward so that the drill bit 202 fits against the civil air defense door, the sealing ring 2081 will also fit against the surface of the civil air defense door. As the drill bit 202 moves downward, the sealing ring 2081 will move upward and push the slide bar 2072 to move into the sleeve 2074. At this time, the sleeve 2074 will squeeze the air in the sleeve 2074 to the telescopic tube 2075 through the piston plate 2073, and quickly enter the airbag 2085 along the telescopic tube 2075. At this time, the airbag 2085 will fill the gap between the sealing ring 2081 and the civil air defense door while expanding. During the drilling process, the driving shaft 201 will not only drive the drill bit 202 to rotate, but also drive several exhaust blades 2094 to rotate through the connecting sleeve 2091, so that the exhaust blades 2094 extract the air below and discharge it upward, and a large amount of gas will enter along the adsorption hole 2082. At this time, the gas will squeeze the sealing plate 2053 to move upward, so that the sealing plate 2053 gradually moves upward and is located in the first sliding pipe 2061, and the extracted gas will quickly enter the first sliding pipe 2061 along the gap between the first sliding pipe 2061 and the sealing plate 2053 and be discharged along the filter screen 2042 above the mounting plate 2041, and the collected metal chips will be blocked by the filter screen 2042 under the filter screen 2042, and after the driving shaft 201 stops running, the spring 2055 will squeeze the sealing plate 2053 to reset, and the metal chips will fall above the sealing plate 2053 under the action of gravity, so as to recover the metal chips; When the drill bit 202 needs to be removed after processing, the drive shaft 201 needs to be run in reverse, so that the drive shaft 201 drives the drill bit 202 and the exhaust fan blades 2094 to rotate in reverse. At this time, the exhaust fan blades 2094 will rotate along the rotator 2092 due to the reverse rotation and contact the shift block 2065. At this time, the shift block 2065 will adjust the angle of the exhaust fan blades 2094, so that the exhaust fan blades 2094 can still extract external gas when rotating in the reverse direction and discharge it upward.
