Description

Technical Field

[0001] The present invention relates to the technical field of pipe drilling, and particularly relates to a metal pipe drilling device. Background Art

[0002] Metal pipes are hollow steel materials with a mainly circular cross-section, and their length is much greater than the diameter or circumference. In the use of pipes, it is inevitable to connect with other components through bolts, and at this time, it is necessary to drill holes in the pipes in advance to meet the connection requirements. At the same time, a metal pipe may need to have multiple holes drilled on different surfaces to meet the usage requirements. The drilling of metal pipes is mainly carried out by a drilling machine. The metal pipe drilling devices in the prior art usually require manual loading and unloading, and for drilling at different positions on the same pipe, it is necessary to reinstall and clamp, which is very inconvenient, with low automation and not conducive to continuous processing.

An upper docking wheel is rotatably installed on the feeding housing. An upper docking gear is also fixedly installed on the upper driving shaft on one side of the upper docking wheel. The upper docking gear meshes with the upper docking wheel. Two lower driving shafts are rotatably installed on the conveying rack. Lower driving wheels are fixedly installed on the lower driving shafts. A lower conveyor belt is wound around the outer side of the lower driving wheels. An outer side wheel is also fixedly installed on the lower driving shaft on one side of the upper docking wheel. An inclined transmission belt is wound around the outer sides of the outer side wheel and the upper docking wheel.

[0007] Further, a plurality of upper notches are provided on the upper pressing belt, and a plurality of lower notches are provided on the lower conveyor belt.

[0008] The top motor drives the motor gear to rotate, drives the driving wheel and some of the gears to rotate through the vertical transmission belt. Some of the gears drive the intermittent gear to rotate intermittently. The intermittent gear drives the upper driving shaft, the upper driving wheel and the upper docking gear to rotate, thereby driving the upper pressing belt to rotate. The intermittent gear drives the lower cylinder gear to rotate through the transverse transmission belt, thereby driving the lower roller, the lower cylinder gear and the lower synchronous wheel to rotate. The upper synchronous wheel and the upper roller are driven to rotate through the synchronous transmission belt. The upper docking gear drives the outer side wheel, the lower driving shaft and the lower driving wheel to rotate through the inclined transmission belt, thereby driving the lower conveyor belt to rotate. The rotation directions of the lower conveyor belt and the upper pressing belt are opposite. Each time some of the gears mesh with the intermittent gear, the upper roller and the lower roller are driven to rotate a quarter of a circle. The lower conveyor belt and the intermittent gear convey the metal pipe to one station through the upper notches and the lower notches.

[0009] Further, the capping mechanism includes an inner pushing block slidably installed on the cover feeding frame. A supporting rod is fixedly installed on the inner pushing block. An inner spring is arranged between the inner pushing block and the cover feeding frame. A semi-friction wheel is fixedly installed on some of the gears. A friction shaft is rotatably installed on the conveying rack. A docking friction wheel is fixedly installed on the friction shaft. The docking friction wheel meshes with the semi-friction wheel. A top arc block is slidably installed on the conveying rack. An inner rotating rod is rotatably installed on the docking friction wheel. The inner rotating rod is rotatably installed with the top arc block. An outer long rotating rod is rotatably installed on the top arc block. An inner pressing rod is rotatably installed on the outer long rotating rod. The inner pressing rod is rotatably installed with the cover feeding frame.

[0010] Further, a plurality of lid modules are placed in the cover feeding frame. The lid module includes a plug body. A plurality of clamping blocks are slidably installed on the outer side of the plug body. A clamping block spring is arranged between the clamping block and the plug body. A plug and a self-rotating gear are fixedly installed on the plug body. The plug is made of rubber material. The plug body of the lid module at the bottom of the cover feeding frame is blocked by the supporting rod.

[0011] Further, an inclined slide plate is slidably installed inside the feed housing. A sliding guide frame is slidably installed on the feed housing. A sliding frame is fixedly installed on the sliding guide frame. The sliding frame is fixedly installed with a jacking arc block. The inclined slide plate is slidably installed with the sliding guide frame.

[0012] A metal pipe to be drilled is placed inside the feed housing. The rotation of some gears drives the semi-friction wheel to rotate, thereby driving the docking friction wheel to rotate intermittently. The docking friction wheel drives the jacking arc block to slide back and forth through the inner rotating rod. The jacking arc block drives the inclined slide plate to slide along the feed housing through the sliding frame and the sliding guide frame. Every time the inclined slide plate slides back and forth, the metal pipe inside the feed housing drops into the lower space of the feed housing. Subsequently, the pipe enters the pipe groove of the upper roller. The inclined setting of the inclined slide plate can push the remaining pipes up when the inclined slide plate rises. The upper roller and the lower roller rotate synchronously. When the pipe enters the pipe groove of the upper roller and reaches below, the pipe falls into the pipe groove of the lower roller. The lower roller drives the pipe to continue rotating. When the pipe reaches in front of the inner pushing block, at this time, some gears are disengaged from the intermittent gear. When the jacking arc block moves, it will also drive the outer long rotating rod and the inner pressing rod to rotate. The inner pushing block is pushed to slide inward through the inner pressing rod, and the inner spring is stretched. The plug is pressed into the end of the metal pipe through the inner pushing block, realizing the capping of both ends of the metal pipe.

[0013] During the process of the upper pressing belt and the lower conveyor belt transporting the metal pipe, the block is limited by the upper notch and the lower notch, so that the metal pipe will not rotate independently during the transportation process.

[0014] Further, the drilling mechanism includes a jacking column fixedly installed on the lifting frame. The jacking column cooperates with the jacking arc block. A spring is provided between the lifting frame and the feed housing. A plurality of drilling seats are fixedly installed on the lifting frame. The position of the drilling seats relative to the lifting frame is adjustable. Drilling guns are provided on the drilling seats. A plurality of self-rotating racks are provided on the conveying frame.

[0015] In the initial state, the jacking arc block jacks up the jacking column and the lifting frame. The spring between the lifting frame and the feed housing is compressed. When the jacking arc block slides along the feed housing, the spring resets and drives the drilling seat and the drilling gun to descend in cooperation with the gravity of the lifting frame. The metal pipe is drilled through the drilling gun. When the metal pipe is transported, the self-rotating gear will contact the self-rotating rack. Under the action of the self-rotating rack, the self-rotating gear and the metal pipe are driven to rotate by ninety degrees, realizing the drilling of different surfaces of the metal pipe. When the metal pipe and the plug body rotate, the block slides relative to the plug body, and the block spring is compressed and then rebounds.

[0016] According to different drilling requirements, the position of the drilling seats relative to the lifting frame, as well as the number of drilling seats, can be set according to the actual situation. The position and number of the self-rotating racks can also be set according to the actual situation.

[0017] That is, when the semi-friction wheel cooperates with the docking friction wheel, some gears do not mesh with the intermittent gear. At this time, the upper roller, the lower roller, the upper pressing belt and the lower conveyor belt do not rotate. The inclined slide plate moves back and forth once, and the metal pipe enters the inner pushing block. The inner pressure rod presses the plug body and the plug into the metal pipe in front of the inner pushing block through the inner pushing block. The lifting frame lifts once, and the metal pipe below it is drilled by the drill gun; when some gears mesh with the intermittent gear, the semi-friction wheel does not mesh with the docking friction wheel, driving the roller frame and the lower roller to rotate 90 degrees, and the upper pressing belt and the lower conveyor belt convey the metal pipe to one station.

[0018] The beneficial effects of the present invention compared with the prior art are as follows: (1) When the semi-friction wheel provided in the present invention cooperates with the docking friction wheel, the metal pipe enters the inner pushing block, and the plug body and the plug are pressed into the metal pipe in front of the inner pushing block through the inner pushing block. The metal pipe below it is drilled by the drill gun. When some gears mesh with the intermittent gear, the roller frame and the lower roller are driven to rotate 90 degrees, and the upper pressing belt and the lower conveyor belt convey the metal pipe to one station, with high automation and good continuity; (2) The lid adding mechanism provided in the present invention plugs the lid module at both ends of the metal pipe, so that the metal pipe will not rotate independently during transportation. At the same time, under the action of the self-rotating rack, it can be automatically flipped to adjust the drilling position, and the drilling stability is good; (3) The number and position of the drilling seat and the self-rotating rack of the drilling mechanism provided in the present invention can be adjusted according to actual needs, and the drilling adaptability is good.

[0037] As Figures 2 - 4As shown in the figure, a number of upper notches 113 are provided on the upper pressing belt 112, and a number of lower notches 120 are provided on the lower conveyor belt 119.

[0038] The top motor 103 drives the motor gear 104 to rotate, drives the transmission wheel 109 and part of the gear 105 to rotate through the vertical transmission belt 106, part of the gear 105 drives the intermittent gear 122 to rotate intermittently, the intermittent gear 122 drives the upper transmission shaft 110, the upper transmission wheel 111 and the upper docking gear 114 to rotate, thereby driving the upper pressing belt 112 to rotate. The intermittent gear 122 drives the lower cylinder gear 124 to rotate through the horizontal transmission belt 123, thereby driving the lower roller 121, the lower cylinder gear 124 and the lower synchronous wheel 126 to rotate, drives the upper synchronous wheel 125 and the upper roller 108 to rotate through the synchronous transmission belt 127. The upper docking gear 114 drives the outer wheel 128, the lower transmission shaft 117 and the lower transmission wheel 118 to rotate through the inclined transmission belt 116, thereby driving the lower conveyor belt 119 to rotate. The rotation directions of the lower conveyor belt 119 and the upper pressing belt 112 are opposite. Every time part of the gear 105 meshes with the intermittent gear 122, it drives the upper roller 108 and the lower roller 121 to rotate a quarter of a circle. The lower conveyor belt 119 and the intermittent gear 122 convey the metal pipe to one station through the upper notch 113 and the lower notch 120.

[0039] As Figures 5 - 10 shown, the capping mechanism includes an inner push block 208 slidably installed on the cap feeding frame 201. A support rod 219 is fixedly installed on the inner push block 208. An inner spring 209 is provided between the inner push block 208 and the cap feeding frame 201. A semi-friction wheel 210 is fixedly installed on part of the gear 105. A friction shaft 211 is rotatably installed on the conveying frame 102. A docking friction wheel 212 is fixedly installed on the friction shaft 211. The docking friction wheel 212 meshes with the semi-friction wheel 210. A top-up arc block 205 is slidably installed on the conveying frame 102. An inner rotating rod 213 is rotatably installed on the docking friction wheel 212. The inner rotating rod 213 is rotatably installed with the top-up arc block 205. An outer long rotating rod 206 is rotatably installed on the top-up arc block 205. An inner pressing rod 207 is rotatably installed on the outer long rotating rod 206. The inner pressing rod 207 is rotatably installed with the cap feeding frame 201.

[0040] As Figures 5 - 10 shown, a number of lid modules are placed in the cap feeding frame 201. The lid module includes a plug body 214. A number of clamping blocks 216 are slidably installed on the outside of the plug body 214. A clamping block spring 217 is provided between the clamping block 216 and the plug body 214. A plug 215 and a self-rotating gear 218 are fixedly installed on the plug body 214. The plug 215 is made of rubber. The plug body 214 of the lid module at the bottom of the cap feeding frame 201 is blocked by the support rod 219.

[0041] As Figures 5 - 10As shown, an inclined slide plate 202 is slidably installed inside the feed housing 101. A sliding guide frame 203 is slidably installed on the feed housing 101. A sliding frame 204 is fixedly installed on the sliding guide frame 203. The sliding frame 204 is fixedly installed with a jacking arc block 205. The inclined slide plate 202 is slidably installed with the sliding guide frame 203.

[0042] A metal pipe to be drilled is placed inside the feed housing 101. Part of the gear 105 rotates to drive the semi-friction wheel 210 to rotate, thereby driving the docking friction wheel 212 to rotate intermittently. The docking friction wheel 212 drives the jacking arc block 205 to slide back and forth through the inner rotating rod 213. The jacking arc block 205 drives the inclined slide plate 202 to slide along the feed housing 101 through the sliding frame 204 and the sliding guide frame 203. Every time the inclined slide plate 202 moves back and forth, the metal pipe inside the feed housing 101 drops into the lower space of the feed housing 101. Subsequently, the pipe enters the pipe groove of the upper roller 108. The inclined slide plate 202 is inclined and can push up the remaining pipes when the inclined slide plate 202 rises. The upper roller 108 and the lower roller 121 rotate synchronously. When the pipe enters the pipe groove of the upper roller 108 and reaches below, the pipe falls into the pipe groove of the lower roller 121. The lower roller 121 drives the pipe to continue rotating. When the pipe reaches in front of the inner pushing block 208, at this time, part of the gear 105 disengages from the intermittent gear 122. When the jacking arc block 205 moves, it will also drive the outer long rotating rod 206 and the inner pressing rod 207 to rotate. The inner pushing block 208 is pushed to slide inward through the inner pressing rod 207, and the inner spring 209 is stretched. The plug 215 is pressed into the end of the metal pipe through the inner pushing block 208, realizing capping at both ends of the metal pipe.

[0043] During the process of the upper pressing belt 112 and the lower conveyor belt 119 conveying the metal pipe, the block 216 is limited by the upper notch 113 and the lower notch 120, so that the metal pipe will not rotate independently during the conveying process.

[0044] As Figure 11 、 Figure 12 As shown, the drilling mechanism includes a jacking column 302 fixedly installed on the lifting frame 301. The jacking column 302 cooperates with the jacking arc block 205. A spring is provided between the lifting frame 301 and the feed housing 101. A number of drilling seats 303 are fixedly installed on the lifting frame 301. The position of the drilling seats 303 relative to the lifting frame 301 is adjustable. Drill guns 304 are provided on the drilling seats 303. A number of self-rotating racks 305 are provided on the conveying frame 102.

[0045] In the initial state, the jacking arc block 205 jacks up the jacking column 302 and the lifting frame 301, and the spring between the lifting frame 301 and the feeding housing 101 is compressed. When the jacking arc block 205 slides along the feeding housing 101, the spring resets and drives the drilling seat 303 and the drill gun 304 to descend under the action of the gravity of the lifting frame 301, and the metal pipe is drilled through the drill gun 304. When the metal pipe is conveyed, the self-rotating gear 218 contacts the self-rotating rack 305, and under the action of the self-rotating rack 305, the self-rotating gear 218 and the metal pipe are driven to rotate by ninety degrees, realizing drilling on different surfaces of the metal pipe. When the metal pipe and the plug body 214 rotate, the clamping block 216 slides relative to the plug body 214, and the clamping block spring 217 is compressed and then rebounds.

[0046] According to different drilling requirements, the position of the drilling seat 303 relative to the lifting frame 301 and the number of the drilling seats 303 can be set according to the actual situation. The position and number of the self-rotating racks 305 can also be set according to the actual situation.

[0047] That is, when the semi-friction wheel 210 cooperates with the docking friction wheel 212, part of the gear 105 does not mesh with the intermittent gear 122. At this time, the upper roller 108, the lower roller 121, the upper pressing belt 112 and the lower conveyor belt 119 do not rotate. The inclined slide plate 202 moves back and forth once, and the metal pipe enters the inner pushing block 208. The inner pressure rod 207 presses the plug body 214 and the plug 215 into the metal pipe in front of the inner pushing block 208 through the inner pushing block 208. The lifting frame 301 lifts and lowers once, and the metal pipe below it is drilled through the drill gun 304. When part of the gear 105 meshes with the intermittent gear 122, the semi-friction wheel 210 does not mesh with the docking friction wheel 212, driving the roller frame 107 and the lower roller 121 to rotate by ninety degrees, and the upper pressing belt 112 and the lower conveyor belt 119 convey the metal pipe by one station.

[0048] The working principle of a metal pipe drilling device disclosed by the present invention is as follows: A metal pipe to be drilled is placed in the feeding shell 101. The top motor 103 drives the motor gear 104 to rotate, drives the transmission wheel 109 and part of the gear 105 to rotate through the vertical transmission belt 106. Part of the gear 105 drives the intermittent gear 122 to rotate intermittently. The intermittent gear 122 drives the upper transmission shaft 110, the upper transmission wheel 111 and the upper docking gear 114 to rotate, thereby driving the upper pressing belt 112 to rotate. The intermittent gear 122 drives the lower cylinder gear 124 to rotate through the horizontal transmission belt 123, thereby driving the lower roller 121, the lower cylinder gear 124 and the lower synchronous wheel 126 to rotate, and drives the upper synchronous wheel 125 and the upper roller 108 to rotate through the synchronous transmission belt 127. The upper docking gear 114 drives the outer wheel 128, the lower transmission shaft 117 and the lower transmission wheel 118 to rotate through the inclined transmission belt 116, thereby driving the lower conveyor belt 119 to rotate. The rotation directions of the lower conveyor belt 119 and the upper pressing belt 112 are opposite. Every time part of the gear 105 meshes with the intermittent gear 122 once, it drives the upper roller 108 and the lower roller 121 to rotate a quarter of a circle. The lower conveyor belt 119 and the intermittent gear 122 convey the metal pipe to a working position through the upper notch 113 and the lower notch 120. A metal pipe to be drilled is placed in the feeding shell 101. Part of the gear 105 rotates to drive the semi-friction wheel 210 to rotate, thereby driving the docking friction wheel 212 to rotate intermittently. The docking friction wheel 212 drives the jacking arc block 205 to slide back and forth through the inner rotating rod 213. The jacking arc block 205 drives the inclined slide plate 202 to slide along the feeding shell 101 through the sliding frame 204 and the sliding guide frame 203. Every time the inclined slide plate 202 moves back and forth, the metal pipe in the feeding shell 101 falls into the lower layer space of the feeding shell 101, and then the pipe enters the pipe groove of the upper roller 108. The inclined slide plate 202 is inclined to push up the remaining pipes when the inclined slide plate 202 rises. The upper roller 108 and the lower roller 121 rotate synchronously. When the pipe enters the pipe groove of the upper roller 108 and reaches below, the pipe falls into the pipe groove of the lower roller 121. The lower roller 121 drives the pipe to continue rotating. When the pipe reaches in front of the inner pushing block 208, at this time part of the gear 105 disengages from the intermittent gear 122. When the jacking arc block 205 moves, it will also drive the outer long rotating rod 206 and the inner pressing rod 207 to rotate. The inner pushing block 208 is pushed to slide inwards through the inner pressing rod 207, and the inner spring 209 is stretched. The plug 215 is pressed into the end of the metal pipe through the inner pushing block 208 to cover both ends of the metal pipe.In the initial state, the jacking arc block 205 jacks up the jacking column 302 and the lifting frame 301, and the spring between the lifting frame 301 and the feeding housing 101 is compressed. When the jacking arc block 205 slides along the feeding housing 101, the spring resets and drives the drilling seat 303 and the drill gun 304 to descend under the gravity of the lifting frame 301, and the metal pipe is drilled through the drill gun 304. When the metal pipe is conveyed, the self-rotating gear 218 contacts the self-rotating rack 305, and under the action of the self-rotating rack 305, the self-rotating gear 218 and the metal pipe are driven to rotate by ninety degrees, realizing the drilling of different surfaces of the metal pipe. When the metal pipe and the plug body 214 rotate, the clamping block 216 slides relative to the plug body 214, and the clamping block spring 217 is compressed and then rebounds.

[0049] That is, when the semi-friction wheel 210 cooperates with the docking friction wheel 212, part of the gear 105 does not mesh with the intermittent gear 122. At this time, the upper roller 108, the lower roller 121, the upper pressing belt 112 and the lower conveyor belt 119 do not rotate. The inclined sliding plate 202 moves back and forth once, and the metal pipe enters the inner pushing block 208. The inner pressing rod 207 presses the plug body 214 and the plug 215 into the metal pipe in front of the inner pushing block 208 through the inner pushing block 208. The lifting frame 301 lifts once, and the metal pipe below it is drilled through the drill gun 304; when part of the gear 105 meshes with the intermittent gear 122, the semi-friction wheel 210 does not mesh with the docking friction wheel 212, driving the roller frame 107 and the lower roller 121 to rotate by ninety degrees, and the upper pressing belt 112 and the lower conveyor belt 119 convey the metal pipe to one station.

[0050] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
