Description

Technical Field

[0001] The present invention relates to the technical field of drilling devices, and more specifically, to a drilling device for air compressor production. Background Art

[0002] An air compressor (referred to as an air compressor for short) is a device used to compress gas. It has a wide range of applications in industrial production and is regarded as one of the "heart" devices of the industry. It is driven by a power source such as an electric motor or a diesel engine, converts the mechanical energy of the prime mover into gas pressure energy, and provides compressed air for various pneumatic devices to achieve various functions such as material transportation, power drive, and gas separation. A flange is an important and indispensable component in an air compressor. It is a disc-shaped part, usually used in pairs, and is mainly used to connect various components of the air compressor, such as the connection between the main engine of the air compressor and the air storage tank, the pipeline and the valve, the cooler and the body, etc. In the production process of the air compressor, drilling the flange through a drilling device is an essential and important link.

[0003] However, during the drilling process of the air compressor flange, the common coolant supply method mostly uses a simple nozzle arrangement. A single injection source is difficult to fully cover all the drill bits of a multi-axis drilling machine. Due to the limitations of the position and spatial layout of different drill shafts and different drill bits on the same drill shaft, there are significant differences in the amount and angle of coolant received, resulting in insufficient cooling of some drill bits and affecting the drilling performance. Moreover, before the drilling machine stops using, there will be some coolant residues inside the nozzle. After the water in the coolant evaporates, some solute components will be left. These components have a certain viscosity and will make the surface of the nozzle easily adsorb dust. The dust adhering to the nozzle surface with sticky substances will cause the nozzle to be blocked and affect subsequent use. At the same time, the blanking operation of the flange mainly relies on manual labor. Since there is cutting fluid remaining on the flange, the cutting fluid will make the surface of the flange relatively smooth. During the manual blanking process, it is inconvenient for the operator to stably grasp and carry the flange, resulting in an increase in the difficulty of the blanking operation and the flange being easily dropped and damaged.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 9As shown in the figure, a drilling device for air compressor production according to the present invention includes a drilling machine body 1, a drilling structure 2 installed on the drilling machine body 1, a cooling structure 3 installed on the drilling machine body 1, a protective structure 5 installed on the drilling structure 2, a blanking structure 4 installed on the drilling machine body 1, and a fixing structure 6 installed on the drilling machine body 1; the drilling structure 2 includes a first hydraulic rod 201 installed on the drilling machine body 1 and a mounting column 202 installed on the telescopic end of the first hydraulic rod 201. A plurality of connecting columns 203 are fixedly connected to the mounting column 202. An installation shaft 204 is rotatably connected to the connecting column 203.

A water pump 306 is installed on the drilling machine body 1. The water inlet of the water pump 306 is fixedly connected to a fixing pipe 305. The other end of the fixing pipe 305 is fixedly connected to the drilling machine body 1. A pipeline 303 is installed at the water outlet of the water pump 306. The pipeline 303 is connected to the installation box 301; the protective structure 5 includes an installation ring 501 fixedly connected to the bottom of the mounting column 202 and a sliding rod 502 slidably connected in the installation ring 501. A protective plate 503 is fixedly connected to the bottom of the sliding rod 502. An installation plate 505 is fixedly connected to the protective plate 503. A guiding wheel 506 is installed on the installation plate 505 through a rotating shaft. The guiding wheel 506 is in rolling cooperation with the driving block 209. A spring 504 is fixedly connected between the sliding rod 502 and the installation ring 501.

[0023] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, a first gear 206 is fixedly connected to the mounting shaft 204, and the multiple first gears 206 are meshed with each other. A first motor 207 is installed inside the mounting column 202, and one of the mounting shafts 204 is fixedly connected to the output shaft of the first motor 207. A counterweight 307 is installed on the pipeline 303. A roller 304 is installed on the drilling machine body 1 through a rotating shaft. A storage basket 308 is installed on the drilling machine body 1, and a filter screen 309 is installed in the storage basket 308. A through hole 310 is provided on the drilling machine body 1. When drilling the flange, place the flange into the mold 605 on the two vertical rods 604, and then start the fourth hydraulic rod 601. When the telescopic end of the fourth hydraulic rod 601 contracts, it will drive the pressing plate 602 to move downward. The pressing plate 602 will slide along the guide post 603. The setting of the guide post 603 makes the movement of the pressing plate 602 smoother, so that the pressing plate 602 fixes the flange, avoiding the rotation of the flange during the processing and affecting the processing effect. When drilling, start the first hydraulic rod 201. When the telescopic end of the first hydraulic rod 201 extends, it drives the mounting column 202 to move downward. The mounting column 202 drives the drill bit 205 to move. During the downward movement of the drill bit 205, start the first motor 207. When the output shaft of the first motor 207 rotates, it drives one of the mounting shafts 204 to rotate. When the mounting shaft 204 rotates, it drives one of the first gears 206 to rotate. One of the first gears 206 drives the multiple first gears 206 to rotate. The first gear 206 drives the mounting shaft 204 to rotate, and the mounting shaft 204 drives the drill bit 205 to rotate. The rotating drill bit 205 moves downward to drill the flange. During the processing, the water pump 306 can be started. When the water pump 306 operates, the cutting fluid will enter the fixed pipe 305 from inside the drilling machine body 1, then enter the pipeline 303 from the outlet of the water pump 306, then enter the installation box 301, and finally be sprayed out from the multiple spray nozzles 302 on the installation box 301. By accurately aligning each spray nozzle 302 with one drill bit 205, the coolant can be directly and precisely sprayed onto the cutting part of each drill bit 205, ensuring the uniform distribution of the coolant, effectively reducing the temperature of the drill bit 205 during the drilling process, ensuring the normal drilling performance of the drill bit 205. At the same time, when the installation box 301 drags the pipeline 303, the pipeline 303 will cause the roller 304 to rotate. The setting of the roller 304 can prevent the pipeline 303 from rubbing against the drilling machine body 1 and causing damage. At the same time, the counterweight 307 applies gravity to prevent the too long pipeline 303 from entering the drilling machine body 1 and affecting the processing. The sprayed coolant will return to the drilling machine body 1 through the through hole 310, and the filter screen 309 on the storage basket 308 filters the waste chips in the coolant to ensure that the coolant can be recycled. When the drilling machine body 1 does not work for a long time, the first hydraulic rod 201 can be fully retracted, and the first hydraulic rod 201 drives the protective plate 503 and the mounting plate 505 to move upward.When the guide wheel 506 rolls and mates with the driving block 209, the guide wheel 506 causes the sliding rod 502 to slide on the mounting ring 501. When the sliding rod 502 slides, the spring 504 contracts, and at the same time, the protective plate 503 rotates to protect the nozzle 302. By rotating the protective plate 503 to the position of the nozzle 302, when the drilling machine body 1 is not in use, it can effectively prevent external dust from contacting the surface of the nozzle 302, avoid dust adhering to the nozzle 302 and causing blockage, and ensure that the nozzle 302 can spray coolant normally during subsequent use.

[0024] Specifically, such as Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 12As shown in the figure, the blanking structure 4 includes a second hydraulic rod 401 installed on the drilling machine body 1 and a connecting rod 402 installed on the telescopic end of the second hydraulic rod 401. A connecting plate 403 is fixedly connected to the connecting rod 402. A sliding plate 404 is slidably connected to the connecting plate 403. A positioning block 405 is fixedly connected to the sliding plate 404. An adjusting rod 407 is installed on the sliding plate 404. A third hydraulic rod 406 is fixedly connected to the connecting plate 403. The adjusting rod 407 is fixedly connected to the telescopic end of the third hydraulic rod 406. The fixing structure 6 includes two fourth hydraulic rods 601 installed on the drilling machine body 1 and a pressing plate 602 installed between the telescopic ends of the two fourth hydraulic rods 601. Two vertical rods 604 are fixedly connected to the drilling machine body 1. A mold 605 is fixedly connected to the vertical rods 604. A guiding column 603 is fixedly connected to the drilling machine body 1. The pressing plate 602 is slidably connected to the guiding column 603. A material pushing structure 7 is provided on the drilling machine body 1. The material pushing structure 7 includes a mounting seat 701 installed on the drilling machine body 1 and a first guiding plate 702 fixedly connected to the mounting seat 701. A second guiding plate 703 is slidably connected to the mounting seat 701. A fifth hydraulic rod 707 is installed on the mounting seat 701. A push rod 706 is fixedly connected to the telescopic end of the fifth hydraulic rod 707. An adjusting plate 704 is fixedly connected to the second guiding plate 703. The adjusting plate 704 is slidably connected to the mounting seat 701. A knob 705 is threadedly connected to the adjusting plate 704. The knob 705 abuts against the mounting seat 701. A collecting structure 9 is provided on the drilling machine body 1. The collecting structure 9 includes a collecting frame 901 installed on the drilling machine body 1 and a lifting plate 902 slidably connected in the drilling machine body 1. The lifting plate 902 is slidably connected to the collecting frame 901. A limiting plate 903 is fixedly connected to the lifting plate 902. A sliding groove 904 is provided in the collecting frame 901. The limiting plate 903 is slidably engaged with the sliding groove 904. A lead screw 905 is rotatably connected to the drilling machine body 1. The lifting plate 902 is threadedly connected to the lead screw 905. A second motor 906 is installed on the drilling machine body 1. The lead screw 905 is fixedly connected to the output shaft of the second motor 906. A positioning column 907 is fixedly connected to the drilling machine body 1. The positioning column 907 is inserted into the collecting frame 901. When blanking, first, the sliding plate 404 and the positioning block 405 are located below the flange. Then, by starting the third hydraulic rod 406, when the telescopic end of the third hydraulic rod 406 extends, it drives the adjusting rod 407 to move upward. The adjusting rod 407 drives the sliding plate 404 to move, and then the flange is located between the two positioning blocks 405. At this time, the sliding plate 404 continues to move upward. When it moves above the mold 605, start the second hydraulic rod 401. When the telescopic end of the second hydraulic rod 401 extends, it drives the connecting rod 402 to move, and the connecting rod 402 drives the connecting plate 403 to move,The connecting plate 403 adjusts the position of the sliding plate 404. When it moves to the mounting seat 701, only the third hydraulic rod 406 needs to be fully retracted to make the flange frame rest on the mounting seat 701. Then, the fifth hydraulic rod 707 is started. The telescopic end of the fifth hydraulic rod 707 drives the push rod 706 to move, causing the push rod 706 to push the flange, and the flange moves along the first guide plate 702 and the second guide plate 703. The settings of the first guide plate 702 and the second guide plate 703 facilitate guiding the flange. Finally, the flange is pushed into the collection box 901 for collection. The sliding plate 404 can move up and down and back and forth, and cooperate with the push rod 706 to push the flange into the collection box 901 to achieve automatic blanking. This avoids situations such as the flange surface becoming smooth due to cutting fluid during the blanking process, resulting in the flange slipping or bumping when the operator grabs and transports it, thereby preventing damage or deformation of the flange surface and affecting the product quality. At the same time, the adjusting plate 704 drives the second guide plate 703 to slide on the mounting seat 701, facilitating the adjustment of the position of the second guide plate 703 according to the flange size. After adjustment, it only needs to be tightened against the mounting seat 701 through the knob 705. When the collection box 901 is installed on the drilling machine body 1, first insert the positioning column 907 on the collection box 901 into the drilling machine body 1, and then start the second motor 906. When the output shaft of the second motor 906 rotates, it drives the lead screw 905 to rotate. The lead screw 905 rotates and thread-drives the lifting plate 902 to move upward. When the lifting plate 902 drives the limiting plate 903 to move into the chute 904, at this time, in cooperation with the positioning column 907, it is convenient to fix the collection box 901 and the drilling machine body 1, improving the stability. At the same time, the upward movement of the lifting plate 902 reduces the height at which the flange drops, avoiding damage caused by the flanges bumping into each other due to too high a dropping height.,

[0025] Specifically, such as Figure 1 、 Figure 5 and Figure 13As shown in the figure, a blowing structure 8 is provided on the drilling machine body 1. The blowing structure 8 includes a sixth hydraulic rod 801 installed on the drilling machine body 1 and a connecting seat 802 installed at the telescopic end of the sixth hydraulic rod 801. A connecting pipe 803 is rotatably connected to the connecting seat 802. A plurality of exhaust holes 804 are provided on the connecting pipe 803. An air pump 806 is installed on the connecting seat 802. An air pipe 805 is installed at the air outlet of the air pump 806. The other end of the air pipe 805 is connected to the connecting pipe 803. A connecting cover 807 is fixedly connected to the connecting seat 802. The connecting pipe 803 is rotatably connected to the connecting cover 807. A second gear 808 is fixedly connected to the connecting pipe 803. A rack 809 is fixedly connected to the drilling machine body 1. A torsion spring 810 is fixedly connected between the connecting pipe 803 and the connecting seat 802. During the drilling process, the air pump 806 can be started. The air pump 806 will cause the gas to enter the connecting pipe 803 through the air pipe 805 and then be discharged through the plurality of exhaust holes 804 on the connecting pipe 803. The discharged gas can blow the waste chips and cutting fluid on the pressing plate 602, so that the waste chips and cutting fluid can return to the drilling machine body 1 faster. When the connecting pipe 803 is not needed, the telescopic end of the sixth hydraulic rod 801 contracts, driving the connecting seat 802 to move upward. By moving the connecting seat 802 upward, it is convenient to adjust the height of the connecting pipe 803, making the blowing effect better. When the second gear 808 meshes with the rack 809, as the connecting seat 802 continues to move upward, the second gear 808 will drive the connecting pipe 803 to rotate, causing the exhaust holes 804 to rotate into the connecting cover 807, preventing the exhaust holes 804 from being blocked by dust and affecting the use. The torsion spring 810 rotates when the connecting pipe 803 rotates.

[0026] When the present invention is in use, when it is necessary to drill the flange, the flange is placed in the mold 605 on the two vertical rods 604, and then the fourth hydraulic rod 601 is started. When the telescopic end of the fourth hydraulic rod 601 contracts, it will drive the pressing plate 602 to move downward. The pressing plate 602 will slide with the guide post 603. The setting of the guide post 603 makes the movement of the pressing plate 602 more stable, so that the pressing plate 602 fixes the flange, avoiding the rotation of the flange during the processing and affecting the processing effect. When drilling, the first hydraulic rod 201 is started. When the telescopic end of the first hydraulic rod 201 extends, it drives the mounting column 202 to move downward. The mounting column 202 drives the drill bit 205 to move. During the downward movement of the drill bit 205, the first motor 207 is started. When the output shaft of the first motor 207 rotates, it drives one of the mounting shafts 204 to rotate. When the mounting shaft 204 rotates, it drives one of the first gears 206 to rotate. One of the first gears 206 drives a plurality of first gears 206 to rotate. The first gear 206 drives the mounting shaft 204 to rotate. The mounting shaft 204 drives the drill bit 205 to rotate. The rotating drill bit 205 moves downward to drill the flange. During the processing, the water pump 306 can be started. When the water pump 306 operates, the cutting fluid will enter the fixed pipe 305 from the drilling machine body 1, then enter the pipeline 303 from the outlet of the water pump 306, then enter the mounting box 301, and finally be sprayed out from the plurality of nozzles 302 on the mounting box 301. By accurately aligning each nozzle 302 with one drill bit 205, the coolant can be directly and precisely sprayed onto the cutting part of each drill bit 205, ensuring the uniform distribution of the coolant, effectively reducing the temperature of the drill bit 205 during the drilling process, and ensuring the normal drilling performance of the drill bit 205. At the same time, when the mounting box 301 drags the pipeline 303, the pipeline 303 will cause the roller 304 to rotate. The setting of the roller 304 can prevent the pipeline 303 from rubbing against the drilling machine body 1 and causing damage. At the same time, the counterweight 307 applies gravity to prevent the too long pipeline 303 from entering the drilling machine body 1 and affecting the processing. The sprayed coolant will return to the drilling machine body 1 through the through hole 310, and the filter screen 309 on the storage basket 308 filters the waste chips in the coolant to ensure that the coolant can be recycled. When the drilling machine body 1 does not work for a long time, the first hydraulic rod 201 can be fully contracted. The first hydraulic rod 201 drives the protective plate 503 and the mounting plate 505 to move upward. When the guide wheel 506 rolls with the driving block 209, the guide wheel 506 will cause the sliding rod 502 to slide on the mounting ring 501. When the sliding rod 502 slides, the spring 504 contracts. At the same time, the protective plate 503 rotates to protect the nozzle 302. By rotating the protective plate 503 to the nozzle 302, when the drilling machine body 1 is not in use, it can effectively block the contact between the outside dust and the surface of the nozzle 302, avoiding dust adhering to the nozzle 302 and causing blockage, and ensuring that the nozzle 302 can normally spray the coolant during subsequent use; During the drilling process, the air pump 806 can be started. The air pump 806 causes the gas to enter the connecting pipe 803 through the trachea 805, and then is discharged through a plurality of exhaust holes 804 on the connecting pipe 803. The discharged gas can blow the waste chips and cutting fluid on the pressing plate 602, so that the waste chips and cutting fluid can return to the drilling machine body 1 faster. When the connecting pipe 803 is not needed, the telescopic end of the sixth hydraulic rod 801 contracts, driving the connecting seat 802 to move upward. By the upward movement of the connecting seat 802, it is convenient to adjust the height of the connecting pipe 803, making the blowing effect better. When the second gear 808 meshes with the rack 809, the connecting seat 802 continues to move upward, causing the second gear 808 to drive the connecting pipe 803 to rotate, so that the exhaust holes 804 rotate into the connecting cover 807, preventing the exhaust holes 804 from being blocked by dust and affecting the use. When the connecting pipe 803 rotates, the torsion spring 810 rotates; During blanking, first place the slide plate 404 and the positioning block 405 below the flange. Then, by activating the third hydraulic rod 406, when the telescopic end of the third hydraulic rod 406 extends, it drives the adjusting rod 407 to move upward. The adjusting rod 407 drives the slide plate 404 to move, and then positions the flange between the two positioning blocks 405. At this time, the slide plate 404 continues to move upward. When it moves above the mold 605, activate the second hydraulic rod 401. When the telescopic end of the second hydraulic rod 401 extends, it drives the connecting rod 402 to move. The connecting rod 402 drives the connecting plate 403 to move, and the connecting plate 403 adjusts the position of the slide plate 404. When it moves to the mounting seat 701, only need to fully retract the third hydraulic rod 406 to place the flange on the mounting seat 701. Then activate the fifth hydraulic rod 707, and the telescopic end of the fifth hydraulic rod 707 drives the push rod 706 to move, so that the push rod 706 pushes the flange, and the flange moves along the first guide plate 702 and the second guide plate 703. The settings of the first guide plate 702 and the second guide plate 703 facilitate guiding the flange. Finally, push the flange into the collection box 901 for collection. The slide plate 404 can move up, down, forward, and backward, and cooperate with the push rod 706 to push the flange into the collection box 901 to achieve automatic blanking, avoiding situations such as slipping and bumping during the blanking process when the surface of the flange becomes smooth due to cutting fluid, thus preventing damage or deformation of the flange surface and affecting product quality. At the same time, the adjusting plate 704 drives the second guide plate 703 to slide on the mounting seat 701, facilitating the adjustment of the position of the second guide plate 703 according to the flange size. After adjustment, just tighten it with the knob 705 against the mounting seat 701. When installing the collection box 901 on the drilling machine body 1, first insert the positioning post 907 on the collection box 901 into the drilling machine body 1. Then activate the second motor 906. When the output shaft of the second motor 906 rotates, it drives the lead screw 905 to rotate. The lead screw 905 rotates to drive the lifting plate 902 to move upward by thread. When the lifting plate 902 drives the limiting plate 903 to move into the chute 904, at this time, in cooperation with the positioning post 907, it is convenient to fix the collection box 901 and the drilling machine body 1, improving the stability. At the same time, the upward movement of the lifting plate 902 reduces the falling height of the flange, avoiding damage caused by mutual collision of the flanges due to too high a falling height.
