Description

Technical Field

[0001] The present invention relates to the technical field of drilling processing, and specifically relates to an automatic drilling device for a flame arrester housing. Background Technique

[0002] With the development of industrial production, the use and transportation of flammable and explosive gases are becoming more and more extensive, and the application of flame arresters is also increasing day by day. A flame arrester is a safety device used to prevent the spread of flames of flammable gases and liquids and prevent flashback from causing explosions. It is usually installed on pipelines and containers for transporting or storing flammable and explosive gases. When the flame in the pipeline or container propagates towards the gas source due to reasons such as flashback, the flame arrester can quickly stop the propagation of the flame, thereby avoiding the occurrence of fire or explosion accidents. The flame arrester housing is an external structural component of the flame arrester, generally made of metal materials. Its function is to protect internal components such as the flame arrestor core, and at the same time connect the flame arrester with the pipeline or equipment to form a complete flame arrestment system.

[0003] However, in the prior art, in the drilling area, oxygen will react with the metal on the surface of the drill bit to form an oxide layer. However, during the drilling process, the oxide layer will reduce the hardness and wear resistance of the drill bit, making the drill bit more prone to wear. The oxide layer on the surface of the drill bit will make the cutting edge blunt, reducing the cutting efficiency and cutting quality of the drill bit, thereby affecting the hole diameter accuracy and quality of the processed flame arrester.

[0004] Therefore, we propose an automatic drilling device for a flame arrester housing to solve the problems mentioned above. Summary of the Invention

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Example 1: Refer to Figures 1 - 8As shown in the figure, the present invention provides a technical solution: an automatic drilling device for a flame arrester housing, which includes a machine tool assembly 1, a drilling assembly 4 and a jet assembly 5. The drilling assembly 4 is used for drilling the flame arrester housing. The jet assembly 5 sprays gas to reduce the oxygen concentration in the drilling area. The drilling assembly 4 includes a fixed block 401 and a metal drill bit 404. The fixed block 401 is used to install the drilling machine equipment for drilling the flame arrester housing. The metal drill bit 404 is a bimetal composite drill bit, which is wrapped with an outer copper alloy around a high-speed steel cutting head. The jet assembly 5 includes a communication tank 503, and nitrogen is injected into the communication tank 503. The bottom of the communication tank 503 is fixedly connected to a nozzle 504. The nitrogen in the communication tank 503 continuously sprays through the nozzle 504 towards the drilling area to ensure that the wear rate of the flame arrester housing during drilling is slowed down. A fixing buckle 505 is fixedly connected to the outer surface of the nozzle 504 near the bottom end. An oxygen sensor 506 is arranged on the inner wall of the fixing buckle 505, and the oxygen sensor 506 is used to detect the oxygen concentration in the drilling area. A driving motor 402 is arranged on the outer surface of the fixed block 401. The output shaft of the driving motor 402 is fixedly connected to a drill chuck 403. The drill chuck 403 is used to install the metal drill bit 404. A vibration sensor 6 is arranged on the outer surface of the driving motor 402. The machine tool assembly 1 includes a machine tool main body 101. A control panel 102 is arranged on the front surface of the machine tool main body 101. A mounting plate 103 is fixedly connected to the rear surface of the machine tool main body 101 near the top. A hydraulic cylinder 104 is arranged on the top of the mounting plate 103. The top end of the hydraulic cylinder 104 is fixedly connected to a top plate 105. A limiting rod 106 is fixedly connected to the top of the mounting plate 103. The top end of the limiting rod 106 slides through the top plate 105 to the outside. The fixed block 401 is fixedly installed on one side of the top plate 105. The communication tank 503 is fixedly installed at the bottom of the fixed block 401. An air pump 501 is arranged on the top of the top plate 105. The output end of the air pump 501 is fixedly connected to a delivery pipe 502. One end of the delivery pipe 502 is fixedly penetrated into the communication tank 503, and the delivery pipe 502 is used to deliver nitrogen to the nozzle 504.

[0032] In this embodiment, during use, first install the metal drill bit 404 in the drill chuck 403, and then install the drill chuck 403 on the output shaft of the drive motor 402. By starting the drive motor 402, the metal drill bit 404 can be driven to rotate. During the drilling process, the vibration sensor 6 is powered on, and a normal vibration range is set. The vibration frequencies and amplitudes of new drill bits and worn drill bits are different. A worn drill bit may have a dull cutting edge, resulting in an increase in cutting force and an increase in vibration amplitude, while the vibration generated by an unworn drill bit during drilling is within the normal vibration range. This detection method avoids the subjectivity of manual experience and the situation where the drilling accuracy of the flame arrester housing fails due to drill bit wear. At this time, it is necessary to start the hydraulic cylinder 104 to lower the drilling equipment, so that the metal drill bit 404 drills the flame arrester housing. Among them, the metal drill bit 404 uses a bimetal composite drill bit, that is, the outer layer is made of copper alloy to wrap the high-speed steel cutter head, which can reduce friction and effectively prevent sparks generated by friction during high-speed drilling. Among them, the function of the limit rod 106 is to determine the stability of the top plate 105 when rising and falling. During drilling, connect the input end of the air pump 501 to the nitrogen storage tank, start the air pump 501, and under the pressure, continuously spray nitrogen through the delivery pipe 502 and the connecting tank 503 at high pressure to the drilling area, thereby reducing the oxygen concentration in the drilling area. At this time, detect the oxygen concentration in the drilling area through the oxygen sensor 506. After the oxygen concentration drops sufficiently, then perform the drilling operation. The continuously sprayed nitrogen reduces the oxygen concentration, which can effectively reduce the phenomenon of the formation of an oxide layer on the drill bit surface, improve the surface quality and corrosion resistance of the flame arrester housing, and prevent the degradation of material properties caused by oxidation.

[0033] Embodiment 2: Figures 1 - 8As shown in the figure, a regulating component 2 is fixedly connected to the top of the main body 101 of the machine tool. The regulating component 2 includes a first bearing plate 201 which is fixedly installed on the top of the main body 101 of the machine tool. Two limiting sliding grooves 204 are formed in the top of the first bearing plate 201. The inner walls of the two limiting sliding grooves 204 are both slidably connected with a first sliding block 205. The tops of the two first sliding blocks 205 are fixedly connected with a second bearing plate 206. A multi-stage electric push rod 202 is arranged inside the first bearing plate 201. One end of the multi-stage electric push rod 202 is fixedly connected with a first connecting plate 203. The first connecting plate 203 is fixedly installed between the two first sliding blocks 205. Two second sliding blocks 208 are fixedly connected to the top of the second bearing plate 206. The outer surfaces of the two second sliding blocks 208 are slidably connected with a third bearing plate 212. A support plate 207 is fixedly connected to one side of the second bearing plate 206. A forward and reverse motor 209 is arranged on the top of the support plate 207. The output shaft of the forward and reverse motor 209 is fixedly connected with an adjusting screw rod 211. A limiting block 210 is fixedly connected between the two second sliding blocks 208 opposite to each other. The outer surface of the adjusting screw rod 211 is rotatably connected with the inner wall of the limiting block 210. A threaded hole 215 is formed in one side of the third bearing plate 212. The outer surface of the adjusting screw rod 211 is threadedly connected with the outer surface of the threaded hole 215. Support frames 213 are fixedly connected to the top of the third bearing plate 212 near the two side edges. A servo motor 214 is arranged on the outer surface of one of the support frames 213. Connecting shafts 216 are arranged on both opposite sides of the support frame 213. The output shaft of the servo motor 214 penetrates through the corresponding support frame 213 and is fixedly connected with one side of one of the connecting shafts 216. The other connecting shaft 216 is fixedly installed on the outer surface of the other support frame 213. An adjusting frame 217 is rotatably connected between the outer surfaces of the two connecting shafts 216.

[0034] In this embodiment, during use, the position of the flame arrester housing is adjusted by the adjusting assembly 2. After clamping the flame arrester housing, the servo motor 214 is started, and its output shaft rotates, thereby driving the connected connecting shaft 216 to rotate. Since the adjusting frame 217 rotates outside the two connecting shafts 216, the clamped flame arrester housing will adjust its angle under the drive of the servo motor 214. Therefore, not only can holes be drilled at both ends of the flame arrester housing, but also holes can be drilled on its side. Next, to adjust the drilling position, the multi-stage electric push rod 202 is started, so that the second bearing plate 206 adjusts its position when the multi-stage electric push rod 202 expands and contracts. At this time, the first slider 205 slides inside the limit chute 204 but will not fall, thereby realizing the movement of the flame arrester housing in the Y-axis direction. By starting the forward and reverse motor 209, its output shaft rotates, thereby driving the third bearing plate 212 to slide outside the second slider 208, and further realizing the movement of the flame arrester housing in the X-axis direction, playing a role in flexibly moving the flame arrester housing, and the position to be drilled can be adjusted directly below the metal drill bit 404 for drilling operation.

[0035] Embodiment Three: Figures 1 - 8 As shown, a positioning component 3 is fixedly connected to the top of the adjusting frame 217. The positioning component 3 includes a positioning base 301. A positioning block 302 is fixedly connected to one side near the top of the positioning base 301. A clamping block 303 is provided on the top of the positioning base 301. Two movable holes 304 are opened on the top of the clamping block 303. The inner walls of the two movable holes 304 are both slidably connected with positioning pins 305. The two positioning pins 305 are both fixedly connected to the top of the positioning base 301. The clamping block 303 and the positioning block 302 are used to clamp the flame arrester housing. A reinforcing block 306 is fixedly connected to the other side of the positioning base 301. A lever 307 is rotatably connected to the inner wall of the reinforcing block 306. One end of the lever 307 is fixedly connected with an eccentric cam 308. The eccentric cam 308 is used to adjust the position of the clamping block 303.

[0036] In this embodiment, when in use, the flame arrester housing must first be fixed in position, and one side of the flame arrester housing is placed between the positioning block 302 and the clamping block 303 so that the flame arrester housing can be clamped by the positioning block 302 and the clamping block 303 to facilitate the automatic drilling operation. During the automatic drilling process, the flame arrester will not be offset. By toggling the lever 307, the outer surface of the eccentric clamping wheel 308 closer to the center of the circle is close to the clamping block 303, so that the space between the clamping block 303 and the positioning block 302 is The distance can be adjusted to the maximum. When the flame arrester housing is placed between the positioning block 302 and the clamping block 303, the lever 307 is toggled, and the eccentric clamping wheel 308 will rotate with the end of the lever 307 as the center of the circle until the eccentric clamping wheel 308 presses the clamping block 303 tightly. The contact surfaces of the two are provided with anti-slip textures, which can enhance the firmness of the clamping. The positioning pin 305 slides inside the movable hole 304, thereby preventing the clamping block 303 from falling off during movement, thereby ensuring the stability of the flame arrester housing clamping.

[0037] The method of use and working principle of the device: when in use, first fix the position of the flame arrester housing, and place one side of the flame arrester housing between the positioning block 302 and the clamping block 303 so that the flame arrester housing can be clamped by the positioning block 302 and the clamping block 303 to facilitate the automatic drilling operation. During the automatic drilling process, the flame arrester will not shift. By toggling the lever 307, the outer surface of the eccentric clamping wheel 308 closer to the center of the circle is close to the clamping block 303, so that the distance between the clamping block 303 and the positioning block 302 can be adjusted to the maximum. When the flame arrester housing is placed between the positioning block 302 and the clamping block 303, toggle the lever 307, then the eccentric clamping wheel 308 will rotate with the end of the lever 307 as the center of the circle until The eccentric clamping wheel 308 presses the clamping block 303 tightly, and the contact surface of the two is provided with anti-skid texture, which can enhance the firmness of the clamping. When in use, the position movement of the flame arrester housing is realized by the adjustment component 2. After the flame arrester housing is clamped, the servo motor 214 is started to rotate its output shaft, thereby driving the connecting shaft 216 connected thereto to rotate. Since the adjustment frame 217 is sleeved on the outside of the two connecting shafts 216 and rotates, the clamped flame arrester housing will adjust its angle under the drive of the servo motor 214. Therefore, not only the two ends of the flame arrester housing can be drilled, but also the side thereof. The next step is to adjust the drilling position, and by starting the multi-stage electric push rod 202, the second bearing plate 206 is extended when the multi-stage electric push rod 202 is extended. The first slider 205 slides in the limiting slide groove 204 but does not fall, thereby realizing the movement of the flame arrester housing in the Y-axis direction. By starting the forward and reverse motor 209 to rotate its output shaft, the third carrier plate 212 is driven to slide outside the second slider 208, thereby realizing the movement of the flame arrester housing in the X-axis direction. The position where a hole needs to be drilled can be adjusted to the position directly below the metal drill bit 404 for drilling operation. When in use, the metal drill bit 404 must first be installed in the drill chuck 403, and then the drill chuck 403 is installed on the output shaft of the drive motor 402. By starting the drive motor 402, the metal drill bit 404 can be driven to rotate. During the drilling process, the vibration sensor 6 is Electrically, a normal vibration range is set. The vibration frequency and amplitude of a new drill bit and a worn drill bit are different. A worn drill bit may have a blunt cutting edge, which increases the cutting force and vibration amplitude. The vibration generated by an unworn drill bit during drilling is within the normal vibration range. This detection method avoids the subjectivity of manual experience and avoids the situation where the drilling accuracy of the flame arrester housing does not meet the standard due to drill wear. At this time, it is necessary to start the hydraulic cylinder 104 to make the drilling equipment descend, so that the metal drill bit 404 drills the flame arrester housing. Among them, the metal drill bit 404 uses a bimetallic composite drill bit, that is, the high-speed steel cutter head is wrapped with an outer layer of copper alloy, which can reduce friction and effectively prevent sparks caused by friction during high-speed drilling.The function of the limiting rod 106 is to determine the stability of the top plate 105 when it rises and falls. During drilling, the input end of the air pump 501 is connected to the nitrogen storage tank, and the air pump 501 is started. Under the pressure, nitrogen is continuously sprayed at a high pressure through the delivery pipe 502 and the connecting tank 503 towards the drilling area, thereby reducing the oxygen concentration in the drilling area. At this time, the oxygen sensor 506 detects the oxygen concentration in the drilling area. After the oxygen concentration has dropped sufficiently, the drilling operation is carried out. The continuously ejected nitrogen reduces the oxygen concentration, which can effectively reduce the formation of an oxide layer on the surface of the drill bit.
