Description

Technical Field

[0001] This invention belongs to the field of drilling machine technology, specifically relating to a high-precision angle steel drilling machine. Background Technology

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. It is divided into equal-sided angle steel and unequal-sided angle steel. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves. Therefore, the production volume of angle steel is also very large. Angle steel drilling machines are a commonly used type of angle steel drilling machinery, possessing advantages such as high precision, high efficiency, and good stability.

[0003] However, existing angle steel drilling machines are not convenient for processing the iron filings produced during use, causing the iron filings to accumulate on the worktable, affecting the processing of subsequent workpieces. In addition, the drilling process generates certain harmful gases and iron filings, which can be easily inhaled by workers, causing significant harm to their health.

[0004] Therefore, it is necessary to provide a high-precision angle steel drilling machine to address the aforementioned technical issues. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision angle steel drilling machine to solve the problem that existing angle steel drilling machines are inconvenient to handle the iron filings and harmful gases generated during use.

[0006] To achieve the above objectives, an embodiment of the present invention provides the following technical solution:

[0007] The high-precision angle steel drilling machine includes: an operating table, a first purification mechanism, a second filtration mechanism, and a third filtration mechanism;

[0008] A drilling device is installed on the operating table, and a purification cavity is drilled inside the operating table;

[0009] The first purification mechanism is installed on the operating table. The first purification mechanism includes a pair of conveying columns. One end of the conveying column is connected to the purification cavity. A corrugated pipe is connected to the conveying column. A first filter screen is provided inside the conveying column.

[0010] The second filtration mechanism is located inside the purification cavity. The second filtration mechanism includes a support platform, and a magnetic block is provided above the support platform. Both ends of the magnetic block are connected to connecting plugs.

[0011] The third filtration mechanism is located on one side of the support platform. The third filtration mechanism is used to further purify the intake air so that harmful components in the air are less likely to remain.

[0012] Furthermore, the side wall of the purification cavity is chiseled with a sliding groove to provide space for the sliding of the limiting slider and to prevent the limiting slider from falling off. A door is provided on one side of the operating table to facilitate the removal of the magnetic block, thereby making it easier to clean the iron filings attracted on the magnetic block.

[0013] Furthermore, a support frame is inserted into the conveying pipe column to support the first filter screen, making it less likely to fall off. The first filter screen is fixed to the support frame, and a handle is installed on the side of the support frame away from the first filter screen for pulling the support frame, making it convenient for operators to operate.

[0014] Furthermore, a pair of control screws are threaded onto the delivery pipe column to push the lower push block to move, so that the lower push block can squeeze the elastic sealing block to improve the sealing performance. One end of the control screw is connected to the lower push block to support and squeeze the elastic sealing block. A connecting bearing is connected between the control screw and the lower push block to prevent the control screw from falling off and to ensure that the rotation of the control screw is not affected.

[0015] An elastic sealing block is fixed at the end of the lower push block away from the control screw, which is used to squeeze the support frame, thereby preventing gas leakage and improving the sealing performance of the device.

[0016] Furthermore, a fixed limiting frame is fixed on the support platform to support the magnetic block in conjunction with the sliding limiting frame, so as to prevent the magnetic block from slipping. A sliding limiting frame is provided on one side of the fixed limiting frame, and a pair of connecting blocks are respectively inserted into the fixed limiting frame and the sliding limiting frame.

[0017] Furthermore, a connecting vertical plate is fixedly connected to the sliding limit frame to connect the limit slider and the sliding limit frame, so that the sliding limit frame will not slip and plays a supporting role. The other end of the connecting vertical plate is connected to the limit slider to support the sliding limit frame and prevent the sliding limit frame from slipping. The limit slider is located in the groove.

[0018] A limiting guide rod is inserted into the limiting slider to support it and prevent it from tilting during sliding, thus limiting its position. The limiting guide rod is fixed to the operating table, and a push spring is connected between the limiting slider and the operating table to pull the limiting slider. This causes the limiting slider to drive the sliding limiting frame, which in turn works with the fixed limiting frame to fix the magnetic block.

[0019] Furthermore, a rotating support wheel is provided on one side of the support platform to drive multiple actuating teeth to rotate, so that the actuating teeth can scrape up the falling iron filings. A rotating transmission shaft is inserted on the rotating support wheel to support the rotating support wheel and drive the rotating support wheel to rotate, thereby playing a transmission role. Multiple evenly distributed actuating teeth are installed on the rotating support wheel to scrape up the iron filings.

[0020] Furthermore, an electric motor is connected to one end of the rotary transmission shaft located outside the operating table, and fixed bearings are connected to both ends of the rotary transmission shaft and the operating table. A support base is provided below the electric motor, and the support base is fixed to the operating table.

[0021] Furthermore, the third filtration mechanism includes a fixing block for supporting and fixing the air pump to prevent the air pump from shaking and falling off. The air pump is installed on the fixing block for sucking out the gas in the operating table to create a negative pressure in the operating table, thereby generating suction at the outlet of the corrugated pipe. The air pump is connected to an exhaust pipe and a suction pipe for transporting gas.

[0022] Furthermore, a placement groove is carved into the fixing block, and a filter element is provided in the placement groove. The filter element includes an activated carbon filter block, a glass fiber filter block, filter cotton, and a second filter screen, which are used to filter the gas, improve the filtration effect, and prevent the discharged gas from containing harmful components.

[0023] The sidewall of the placement groove has multiple evenly distributed ventilation holes to facilitate gas flow.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] This invention improves the chip removal effect of the angle steel drilling machine by setting the corresponding mechanism, so that the chips and harmful gases can be dealt with as soon as they are generated, thus making it less likely for chips to remain on the workbench surface, which in turn makes it less likely to affect the processing of subsequent workpieces, and also protects the health of the workers.

[0039] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0040] This invention discloses a high-precision angle steel drilling machine, such as... Figures 1-11 As shown, it includes: an operating table 1, a first purification mechanism 2, a second filtration mechanism 3, and a third filtration mechanism 4.

[0041] like Figures 1-11 As shown, a drilling device 101 is installed on the operating table 1. A purification cavity is carved inside the operating table 1. A sliding groove is carved on the side wall of the purification cavity to provide space for the sliding of the limit slider 307 and to prevent the limit slider 307 from falling off. A box door 102 is provided on one side of the operating table 1 to facilitate the removal of the magnetic block 302, thereby facilitating the cleaning of the iron filings attracted on the magnetic block 302.

[0042] Preferably, the door 102 is fixed to the operating table 1 with bolts to prevent gas leakage.

[0043] like Figures 1-7 As shown, the first purification mechanism 2 is installed on the operating table 1. The first purification mechanism 2 includes a pair of conveying columns 201 for conveying gas and supporting the corrugated pipe 202 to prevent the corrugated pipe 202 from falling off. One end of the conveying column 201 is connected to the purification cavity. The corrugated pipe 202 is connected to the conveying column 201. A first filter screen 209 is provided inside the conveying column 201 for the first filtration of the gas, so that larger iron filings and impurities can be screened out.

[0044] like Figures 1-9 As shown, a support frame 203 is inserted into the conveying column 201 to support the first filter screen 209, making it difficult for the first filter screen 209 to fall off. The first filter screen 209 is fixed on the support frame 203. A handle 204 is installed on the side of the support frame 203 away from the first filter screen 209 for pulling the support frame 203, making it convenient for the operator to operate.

[0045] like Figures 1-9 As shown, a pair of control screws 205 are threaded onto the delivery column 201 to push the pressing block 206 to move, so that the pressing block 206 can squeeze the elastic sealing block 208 to improve the sealing performance. One end of the control screw 205 is connected to the pressing block 206 to support and squeeze the elastic sealing block 208. A connecting bearing 207 is connected between the control screw 205 and the pressing block 206 to prevent the control screw 205 from falling off and to ensure that the rotation of the control screw 205 is not affected.

[0046] Specifically, an elastic sealing block 208 is fixed to the end of the pressing push block 206 away from the control screw 205, which is used to squeeze the support frame 203, so that gas will not leak and the sealing performance of the device is improved.

[0047] like Figures 1-11 As shown, the second filter mechanism 3 is located inside the purification cavity. The second filter mechanism 3 includes a support platform 301 for supporting the fixed limiting frame 304, so that the fixed limiting frame 304 will not fall off, and facilitates the sliding of the sliding limiting frame 305. A magnetic block 302 is provided above the support platform 301 for attracting iron filings, thereby separating the iron filings in the air and improving the purification effect. Both ends of the magnetic block 302 are connected to connecting plugs 303.

[0048] like Figures 1-10 As shown, a fixed limiting frame 304 is fixed on the support platform 301 to cooperate with the sliding limiting frame 305 to support the magnetic block 302 and prevent the magnetic block 302 from slipping. A sliding limiting frame 305 is provided on one side of the fixed limiting frame 304, and a pair of connecting blocks 303 are respectively inserted into the fixed limiting frame 304 and the sliding limiting frame 305.

[0049] like Figures 1-11 As shown, a connecting vertical plate 306 is fixedly connected to the sliding limit frame 305, which is used to connect the limit slider 307 and the sliding limit frame 305, so that the sliding limit frame 305 will not slip and plays a supporting role. The other end of the connecting vertical plate 306 is connected to the limit slider 307, which is used to support the sliding limit frame 305 and prevent the sliding limit frame 305 from slipping. The limit slider 307 is set in the slide groove.

[0050] like Figures 1-11 As shown, a limiting guide rod 308 is inserted on the limiting slider 307 to support the limiting slider 307 and prevent it from tilting during sliding. The limiting guide rod 308 is fixed to the operating table 1. A push spring 309 is connected between the limiting slider 307 and the operating table 1 to pull the limiting slider 307. This causes the limiting slider 307 to drive the sliding limiting frame 305, which in turn works with the fixed limiting frame 304 to fix the magnetic block 302.

[0051] like Figures 1-3 As shown, a rotating support wheel 310 is provided on one side of the support platform 301, which is used to drive multiple actuating teeth 312 to rotate, so that the actuating teeth 312 can scrape up the falling iron filings. A rotating transmission shaft 311 is inserted on the rotating support wheel 310, which is used to support the rotating support wheel 310 and drive the rotating support wheel 310 to rotate, thus playing a transmission role. Multiple evenly distributed actuating teeth 312 are installed on the rotating support wheel 310 for scraping up iron filings.

[0052] like Figures 1-3 As shown, a motor 313 is connected to one end of the rotary transmission shaft 311 located outside the operating table 1. Fixed bearings are connected between both ends of the rotary transmission shaft 311 and the operating table 1. A support base 314 is provided below the motor 313 and is fixed to the operating table 1.

[0053] like Figures 1-4 As shown, the third filtration mechanism 4 is used to further purify the intake air, making it less likely for harmful components in the air to remain. The third filtration mechanism 4 includes a fixing block 401, which is used to support and fix the air pump 402 to prevent the air pump 402 from shaking and falling off. The air pump 402 is installed on the fixing block 401 to suck out the gas in the operating table 1, so that a negative pressure is formed in the operating table 1, thereby generating suction at the outlet of the bellows 202. The air pump 402 is connected to an exhaust pipe 403 and a suction pipe 404 for transporting gas.

[0054] like Figures 1-4 As shown, a placement groove is carved into the fixing block 401, and a filter element is installed in the placement groove. The filter element includes an activated carbon filter block 405, a glass fiber filter block 406, a filter cotton 407, and a second filter screen 408, which are used to filter the gas, improve the filtration effect, and prevent the exhaust gas from containing harmful components. Multiple evenly distributed vent holes 409 are carved into the side wall of the placement groove to facilitate the flow of gas.

[0055] In actual use, the electric motor 313 and the air pump 402 will also start during the drilling process of the drilling device 101. During the start-up process of the air pump 402, air will be drawn out through the air extraction pipe 404, thereby creating a negative pressure in the operating table 1, which in turn creates suction at the outlet of the bellows 202, sucking away all the iron filings, impurities and harmful gases generated during the processing, preventing workers from inhaling harmful gases, and also enabling quick cleaning of iron filings.

[0056] Gas and iron filings enter the drilling device 101 through the bellows 202, and then pass through the first filter screen 209, which blocks larger iron filings. Some iron powder and harmful gases enter the operating table 1. The iron powder is attracted by the magnetic block 302 and will not slide down. The start of the motor 313 drives the rotating support wheel 310 and multiple actuating teeth 312 to rotate through the rotating transmission shaft 311. The actuating teeth 312 scrape up the iron filings that have rolled down and throw them back at the magnetic block 302, thus achieving the effect of removing iron filings.

[0057] Harmful gases flow through the vent 409, then pass through the second filter 408, filter cotton 407, glass fiber filter block 406 and activated carbon filter block 405 in sequence, and are then discharged through the exhaust pipe 403, thus removing harmful components.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
