Description

Technical Field

[0001] The invention relates to the technical field of drilling processing, and in particular to a drilling positioning device for processing a civil airtight door. Background Art

[0002] Civil air defense closed doors are one of the important protective equipment in civil air defense projects. In emergency situations, they can prevent harmful radioactive substances, chemical agents, and shock waves, flames, and fragments generated by bomb explosions from entering the interior of civil air defense projects, thereby protecting the safety of internal personnel and equipment.

[0003] During the processing of civil air defense closed doors, it is necessary to drill holes on them to meet the installation of locks or other needs. Since the sealing requirements of civil air defense closed doors are high, the drilling position needs to be accurately positioned during drilling to avoid drilling deviations that affect the sealing. Therefore, a drilling positioning device is required for auxiliary operations.

[0004] During the use of the existing drilling positioning device, only the initial drilling position of the drill bit relative to the civil air defense sealed door can be adjusted. Since the civil air defense sealed door is thick and the material strength is high, the resistance encountered by the drill bit during the drilling process will cause it to vibrate to a certain extent. At this time, the vibration may cause a certain deviation in the drilling position, resulting in a decrease in the accuracy of the drilling size. In addition, a large amount of debris generated during the drilling process may adhere to the drill bit due to heat, affecting the drilling effect and the service life of the drill bit. Therefore, it is necessary to design a drilling positioning device for civil air defense sealed door processing. Summary of the invention

[0040] Reference Figure 1-Figure 14 A drilling positioning device for processing a civil airtight door includes a motor 3, a drill bit 13, and a door body 2 placed on a workbench 1. Since the civil airtight door is large in size and heavy in weight, its own weight can ensure its stability on the workbench 1 during drilling, so there is no need to install additional components on the workbench 1 to fix the door body 2. The size of the drill bit 13 is selected according to the required drilling size, and the specific specifications are not described here. The motor 3 can specifically use a servo motor of model 130ST-M05025LFB, and also includes:

[0041] The drilling positioning part is used to adjust the drilling position of the drill bit 13 relative to the door body 2. The drilling positioning part includes a mounting frame 4 slidably mounted on the workbench 1 through an adjusting component. The adjusting component consists of an adjusting block, an adjusting slot 6, an adjusting screw 7 and an adjusting wheel 5. The adjusting block is fixedly mounted on the mounting frame 4. The adjusting slot 6 is opened at the bottom of the workbench 1, and the adjusting slot 6 cooperates with the adjusting block. The adjusting screw 7 is rotatably mounted on the workbench 1, and one end of the adjusting screw 7 located in the adjusting slot 6 is threadedly connected to the adjusting block. The adjusting wheel 5 is fixedly mounted on the end of the adjusting screw 7 located outside the workbench 1. By rotating the adjusting wheel 5, the adjusting screw 7 can drive the adjusting block to move in the adjusting slot 6, so that the position of the mounting frame 4 relative to the workbench 1 can be adjusted, and the position of the drill bit 13 installed on the mounting frame 4 relative to the door body 2 can be regulated to achieve adjustment and positioning of the drilling position.

[0042] A support column 8 is fixedly mounted on the mounting frame 4, and a lifting assembly matched with the motor 3 is mounted on the support column 8. The drill bit 13 is fixedly mounted on the output end of the motor 3 through the mounting shaft 12. The lifting assembly consists of a lifting screw 9, a connecting plate 10, a gear connector 11, an alignment gear 14 and two guide rods 15.

[0043] The lifting screw rod 9 is rotatably installed on the support column 8, and the connecting plate 10 is threadedly connected to the lifting screw rod 9, and the connecting plate 10 is fixedly connected to the motor 3. When the lifting screw rod 9 rotates, the motor 3 can be driven by the connecting plate 10 to move up and down, so that the upper and lower spacing of the drill bit 13 relative to the door body 2 can be adjusted. At this time, the drill bit 13 is rotated, so that the door body 2 can be drilled in the process of continuous downward movement. The gear connecting piece 11 is fixedly installed on the output end of the motor 3, and the alignment gear 14 is slidably installed on the lifting screw rod 9, and the alignment gear 14 cooperates with the gear connecting piece 11. The two guide rods 15 are fixedly installed on the side walls of the lifting screw rod 9, and the two guide rods 15 are slidably matched with the alignment gear 14. The gear connection Component 11 is composed of a fixed gear and two positioning plates. The two positioning plates are fixedly mounted at the upper and lower ends of the fixed gear respectively, and the diameters of the two positioning plates are larger than the diameter of the fixed gear. Under the action of the two positioning plates, the meshing effect of the alignment gear 14 and the fixed gear can be guaranteed. Under the guiding action of the guide rod 15, the horizontal angle of the alignment gear 14 relative to the lifting screw 9 can be limited, and the alignment gear 14 can slide up and down relative to the lifting screw 9. Therefore, when the motor 3 is working, the lifting screw 9 can be rotated through the meshing of the fixed gear and the alignment gear 14. At this time, the rotation of the lifting screw 9 will drive the motor 3 to move up and down through the connecting plate 10, so that the drill bit 13 moves up and down during the rotation process;

[0044] In addition, in order to ensure that the connecting plate 10 can move up and down stably when the lifting screw 9 rotates, a limiting mechanism that cooperates with the connecting plate 10 can be set on the mounting frame 4, wherein the limiting mechanism can be composed of a limiting plate, a limiting rod and a limiting groove, the limiting plate is fixedly mounted on the top of the mounting frame 4, the limiting rod is fixedly mounted on the side wall of the connecting plate 10, the limiting groove is opened on the side wall of one end of the limiting plate close to the lifting screw 9, and the limiting groove and the limiting rod slide up and down in cooperation, the above-mentioned limiting mechanism is a more common technical means, so it is not shown in the figure.

[0045] The cooling and flushing part is used to cool the drill hole and flush the debris. The cooling and flushing part includes a coolant spray hole 16 opened on the drill bit 13 and a sealing connector 17 rotatably connected to the drill bit 13, wherein the coolant spray hole 16 is an inverted "Y-shape" and has a plurality of through holes on the top side wall thereof. An annular groove that is sealed and rotatably matched with the sealing connector 17 is provided on the side wall of the drill bit 13. A storage tank 19 is fixedly installed on the side wall of the support column 8, and a liquid inlet pipe is fixedly connected between the bottom of the storage tank 19 and the sealing connector 17. 18, and the liquid inlet pipe 18 cooperates with the coolant spray hole 16, and the storage tank 19 is used to store the coolant. When the internal pressure increases, the liquid inlet pipe 18 can transport the coolant from the storage tank 19 to the sealing connector 17 and spray it out from the coolant spray hole 16. At this time, due to the pressure, the sprayed coolant will flush the debris formed by the drilling from the hole position during the drilling process to avoid the problem of debris remaining in the hole position and causing adhesion to the drill bit 13. At the same time, the coolant can also cool the drill bit 13 and the drilling position of the door body 2 to prevent thermal damage.

[0046] The guide protection part is used to guide the drilling process of the drill bit 13 and to block and intercept the debris formed by the drilling. The guide protection part includes a connecting sleeve 21 fixedly installed on the lower end of the motor 3 through an L-shaped frame 20, and a positioning sleeve 22 is installed at the bottom of the connecting sleeve 21. The positioning sleeve 22 and the connecting sleeve 21 are coaxial with the drill bit 13. A plurality of suction cups 24 are fixedly installed on the side wall of the positioning sleeve 22 through a fixing ring 23. Under the action of the L-shaped frame 20, when the motor 3 moves, it can drive the connecting sleeve 21 and the positioning sleeve 22 to move at the same time. At the same time, by using a plurality of suction cups 24, when the positioning sleeve 22 contacts the surface of the door body 2, the downward pressure effect is utilized to make the suction cups 24 firmly adsorbed to the surface of the door body 2, thereby guiding the drilling direction of the drill bit 13, reducing the problem of deviation of the drilling position caused by its sliding relative to the door body 2 due to vibration, and improving the drilling positioning effect.

[0047] A pressure assembly that matches the storage tank 19 is installed between the connecting sleeve 21 and the positioning sleeve 22. The pressure assembly consists of a cavity, a piston ring 27, two pressure-boosting pipes 25, a plurality of L-shaped rods 26, and a plurality of springs 28. The cavity is opened in the connecting sleeve 21, and the piston ring 27 is sealingly and slidably installed in the cavity. The two pressure-boosting pipes 25 are connected between the top of the cavity and the top of the storage tank 19, and the plurality of L-shaped rods 26 are fixedly installed between the bottom of the piston ring 27 and the positioning sleeve 22. The plurality of springs 28 are installed between the top of the piston ring 27 and the cavity. During the drilling process, the positioning sleeve 22 It first contacts the door body 2. As the motor 3 continues to move downward, the positioning sleeve 22 is affected by the reaction force of the door body 2 and approaches the connecting sleeve 21. At this time, multiple L-shaped rods 26 push the piston ring 27 to move upward in the cavity. The air pressure at the upper end of the cavity increases, and the storage tank 19 is pressurized by the existence of two booster pipes 25. At this time, the coolant in the storage tank 19 will be input into the sealing connector 17 through the liquid inlet pipe 18 under the action of pressure, and then the coolant will be sprayed out from the coolant spray hole 16 to flush the debris in the hole and cool the hole and the drill bit 13.

[0048] The side wall of the storage tank 19 is also fixedly connected with an adding pipe, and the other end of the adding pipe is connected to the coolant pool. The coolant pool is a pool filled with coolant. The adding pipe and the liquid inlet pipe 18 are both one-way pipes, wherein the adding pipe allows the coolant in the coolant pool to enter the storage tank 19 in one direction, and the liquid inlet pipe 18 allows the coolant in the storage tank 19 to enter the sealing connector 17 in one direction. Through the design of the adding pipe, when the piston ring 27 moves downward in the cavity, the coolant in the coolant pool can be drawn into the storage tank 19 for replenishment. The inner wall volume of the storage tank 19 is larger than the volume of the cavity. Through the design of the volume, it can be ensured that when the piston ring 27 moves up and down, the coolant can smoothly flow in the coolant pool, the storage tank 19 and the sealing connector 17, thereby avoiding the problem of the coolant entering the cavity through the boost pipe 25.

[0049] The debris cleaning part is used to remove the debris generated by drilling. The debris cleaning part includes a groove 31 opened at the bottom of the positioning sleeve 22, and a debris collection component matched with the positioning sleeve 22 is installed in the groove 31. The debris collection component consists of a suction port 32, a sealing ring 33, an alignment port 34 and two connecting pipes 30. The suction port 32 is opened on the top wall of the groove 31, and the suction port 32 is communicated with the pressure chamber 29. An annular groove 44 is opened on the side wall of the suction port 32. The sealing ring 33 is rotatably installed in the annular groove 44. The alignment port 34 is opened on the sealing ring 33, and the alignment port 34 matches the suction port 32. The two connecting pipes 30 are It is fixedly connected between the top of the pressure chamber 29 and the bottom of the cavity. When the connecting sleeve 21 moves upward relative to the positioning sleeve 22, the air pressure in the lower end of the cavity will continue to decrease as the piston ring 27 moves upward. At this time, the air pressure in the pressure chamber 29 is reduced under the action of the connecting pipe 30. When the suction port 32 corresponds to the position of the alignment port 34, the negative pressure in the pressure chamber 29 can draw the debris blocked by the positioning sleeve 22 during the drilling process into the pressure chamber 29 for collection, so as to avoid the continuous accumulation of debris and adverse effects on drilling. The boost pipe 25 and the connecting pipe 30 are both hoses. The design of the hose is to ensure that the connecting sleeve 21 and the positioning sleeve 22 can move smoothly.

[0050] A sweeping mechanism is also installed in the groove 31, and the sweeping mechanism consists of an annular groove 2 45, a rotating ring, a mounting ring 42 and a sweeping plate 43. The annular groove 2 45 is opened on the side wall of the groove 31, and the rotating ring is rotatably installed in the annular groove 2 45. The sweeping plate 43 is fixedly installed on the inner wall of the rotating ring through the mounting ring 42. The position of the sweeping plate 43 on the mounting ring 42 corresponds to the position of the alignment port 34 on the sealing ring 33. Through the design of the sweeping plate 43, when the mounting ring 42 rotates, the flushed debris can be gathered. When the alignment port 34 is opposite to the suction port 32, the sweeping plate 43 just gathers the debris to the lower end of the suction port 32, thereby facilitating a better completion of the debris collection operation.

[0051] A driving mechanism matched with the sealing ring 33 and the rotating ring is installed between the connecting sleeve 21 and the positioning sleeve 22. The driving mechanism is composed of a mounting block 36, a hollow column 37, a fixing rod 39, a fixing ring gear 1 35, a connecting gear 1 38, a fixing ring gear 2 40 and a connecting gear 2 41.

A spiral groove is provided on the inner wall of the hollow column 37, and a convex block matched with the spiral groove is fixedly mounted on the side wall of the fixing rod 39. Through the cooperation between the spiral groove and the fixing rod 39, when the positioning sleeve 22 moves relative to the connecting sleeve 21, the hollow column 37 can be rotated on the mounting block 36;

[0052] The connecting gear 1 38 and the connecting gear 2 41 are both fixedly mounted on the hollow column 37, the fixed gear ring 1 35 is fixedly mounted on the side wall of the sealing ring 33, and the fixed gear ring 1 35 is meshed with the connecting gear 1 38, the fixed gear ring 2 40 is fixedly mounted on the side wall of the rotating ring, and the fixed gear ring 2 40 is meshed with the connecting gear 2 41. When the hollow column 37 rotates, the sealing ring 33 and the rotating ring can rotate in the positioning sleeve 22 at the same time by utilizing the meshing of the connecting gear 1 38 and the fixed gear ring 1 35 and the meshing of the connecting gear 2 41 and the fixed gear ring 2 40, thereby automatically completing the collection and processing of the debris.

[0053] In the present invention, the working principle of a drilling positioning device for processing a civil airtight door is as follows:

[0054] Drilling positioning: Use a crane or other equipment to place the door body 2 to be processed on the workbench 1, manually rotate the adjusting wheel 5 to move the mounting frame 4 on the workbench 1, and adjust the position of the drill bit 13 relative to the door body 2 to achieve positioning of the drilling position;

[0055] Drilling: After the drill bit 13 is positioned relative to the door body 2, the motor 3 is started to drive the drill bit 13 to rotate clockwise. At this time, the drill bit 13 is allowed to keep rotating while moving downward relative to the door body 2 under the operation of the lifting assembly to complete the drilling process;

[0056] Guiding treatment during drilling: In the early stage of drilling, the motor 3 moves downward to drive the connecting sleeve 21 and the positioning sleeve 22 to move downward at the same time. When the positioning sleeve 22 contacts the surface of the door body 2, the suction cup 24 is firmly adsorbed to the surface of the door body 2 by the pressure of continuous downward movement, thereby guiding the drilling direction of the drill bit 13, reducing the problem of deviation in the drilling position caused by sliding relative to the door body 2 due to vibration, and improving the drilling positioning effect;

[0057] Debris flushing and cooling treatment during drilling: After the positioning sleeve 22 contacts the door body 2, the continuous downward movement of the connecting sleeve 21 causes the piston ring 27 to move upward in the cavity. At this time, the booster pipe 25 inputs high-pressure gas into the storage tank 19, wherein the coolant enters the coolant spray hole 16 from the sealing connector 17 through the liquid inlet pipe 18 under the action of high pressure and is sprayed out, cooling the drilling position and the drill bit 13 to prevent the debris from sticking to the drill bit 13 at high temperature and affecting the drilling effect. At the same time, the pressure and the continuous rotation of the drill bit 13 can also flush out the debris in the drill hole to prevent it from accumulating in the drill hole and causing the drill bit 13 to be blocked;

[0058] Debris collection during drilling: The continuous downward movement of the connecting sleeve 21 relative to the positioning sleeve 22 will also generate negative pressure in the pressure chamber 29 through the connecting pipe 30. At the same time, with the cooperation of the fixing rod 39 and the hollow column 37, the meshing of the connecting gear 1 38 and the fixed gear ring 1 35 and the meshing of the connecting gear 2 41 and the fixed gear ring 2 40 can be used to make the sealing ring 33 and the rotating ring rotate in the positioning sleeve 22 at the same time. At this time, the rotating ring drives the mounting ring 42 and the sweeping plate 43 to rotate, so as to collect the debris generated by drilling;

[0059] At the same time, the rotation of the sealing ring 33 will also adjust the position of the alignment port 34 and the suction port 32 thereon. When the alignment port 34 and the suction port 32 are positioned relative to each other, the sweeping plate 43 will just gather the debris to the lower end of the suction port 32. At this time, the negative pressure in the pressure chamber 29 can draw the debris into it for collection, thereby avoiding the accumulation of debris and causing adverse effects on the drilling process.

[0060] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
