Description

Technical Field

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

[0002] A metal pipe is a hollow steel material with a mainly circular cross-section, and its length is much larger than its diameter or circumference. In the use of the pipe, it is inevitable to connect it with other components through bolts. At this time, it is necessary to drill holes in the pipe in advance to meet the connection requirements. At the same time, a metal pipe may need to have multiple holes on different surfaces to meet the use requirements. The drilling of metal pipes is mainly carried out by a drilling machine. The metal pipe drilling equipment in the prior art usually requires manual loading and unloading, and drilling holes in different positions of the same pipe requires re-clamping, which is very inconvenient, has a low degree of automation, and is not convenient for continuous processing.

[0007] Furthermore, the upper pressing belt is provided with a plurality of upper notches, and the lower conveying belt is provided with a plurality of lower notches.

[0008] The top motor drives the motor gear to rotate, which drives the transmission wheel and some gears to rotate through the vertical transmission belt. Some gears drive the intermittent gears to rotate intermittently. The intermittent gears drive the upper transmission shaft, the upper transmission wheel and the upper docking gear to rotate, thereby driving the upper compression belt to rotate. The intermittent gears drive the lower drum gear to rotate through the horizontal transmission belt, thereby driving the lower drum, the lower drum gear and the lower synchronous wheel to rotate. The upper synchronous wheel and the upper drum are driven to rotate through the synchronous transmission belt. The upper docking gear drives the outer wheel, the lower transmission shaft and the lower transmission wheel to rotate through the oblique transmission belt, thereby driving the lower conveyor belt to rotate. The rotation directions of the lower conveyor belt and the upper compression belt are opposite. Each time the partial gears mesh with the intermittent gears, they drive the upper drum and the lower drum to rotate a quarter of a turn. The lower conveyor belt and the intermittent gears transport the metal pipe to one station through the upper and lower slots.

[0009] Furthermore, the capping mechanism includes an inner push block slidably mounted on the cap feeding frame, a support rod is fixedly mounted on the inner push block, an inner spring is arranged between the inner push block and the cap feeding frame, a semi-friction wheel is fixedly mounted on some gears, a friction shaft is rotatably mounted on the conveying frame, a docking friction wheel is fixedly mounted on the friction shaft, the docking friction wheel is meshed with the semi-friction wheel, a top arc block is slidably mounted on the conveying frame, an inner rotating rod is rotatably mounted on the docking friction wheel, the inner rotating rod is rotatably mounted with the top arc block, an outer long rotating rod is rotatably mounted on the top arc block, an inner pressure rod is rotatably mounted on the outer long rotating rod, and the inner pressure rod is rotatably mounted with the cap feeding frame.

[0010] Furthermore, a plurality of cover modules are placed in the cover input rack, and the cover modules include a plug body, a plurality of clamping blocks are slidably installed on the outside 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, and the plug body of the cover module located at the bottom of the cover input rack is blocked by a support rod.

[0011] Furthermore, an inclined slide plate is slidably installed in the feed shell, a sliding guide frame is slidably installed on the feed shell, a sliding frame is fixedly installed on the sliding guide frame, the sliding frame is fixedly installed on the top arc starting block, and the inclined slide plate is slidably installed on the sliding guide frame.

[0012] The metal pipe to be drilled is placed in the feed shell, and 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 top arc block to slide back and forth through the inner rotating rod, and the top arc block drives the inclined slide plate to slide along the feed shell through the sliding frame and the sliding guide frame. Every time the inclined slide plate moves back and forth, the metal pipe in the feed shell falls into the lower space of the feed shell, and then the pipe enters the pipe groove of the upper roller. The inclined slide plate is inclined to push up the remaining pipes 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, after the pipe groove reaches the bottom, the pipe falls into the pipe groove of the lower roller, and the lower roller continues to rotate with the pipe. When the pipe reaches the front of the inner pushing block, some gears are disengaged from the intermittent gears. When the top arc block moves, it will also drive the outer long rotating rod and the inner pressure rod to rotate, and the inner push block is pushed inward by the inner pressure rod. The inner spring is stretched, and the plug is pressed into the end of the metal pipe through the inner push block, so that the two ends of the metal pipe are covered.

[0013] When the upper pressing belt and the lower conveying belt are conveying the metal pipe, the clamping block is limited by the upper notch and the lower notch, so that the metal pipe will not rotate autonomously during the conveying process.

[0014] Furthermore, the drilling mechanism includes a lifting column fixedly mounted on the lifting frame, the lifting column cooperates with the lifting arc block, a spring is arranged between the lifting frame and the feed shell, a plurality of drilling seats are fixedly mounted on the lifting frame, the position of the drilling seats relative to the lifting frame is adjustable, a drilling gun is arranged on the drilling seat, and a plurality of self-rotating racks are arranged on the conveying frame.

[0015] In the initial state, the jacking arc block jacks up the jacking column and the lifting frame, and the spring between the lifting frame and the feed shell is compressed. When the jacking arc block slides along the feed shell, the spring resets and cooperates with the gravity of the lifting frame to drive the drilling seat and the drill gun to descend, and the metal pipe is drilled by the drill gun. When the metal pipe is conveyed, 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 ninety degrees to realize drilling on 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 seat relative to the lifting frame and the number of the drilling seats can be set according to actual conditions, and the position and number of the self-rotating racks can also be set according to actual conditions.

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

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) When the semi-friction wheel provided in the present invention cooperates with the docking friction wheel, the metal pipe enters the inner push block, and the plug body and the plug are pressed into the metal pipe in front of the inner push block by the inner push block, and the metal pipe below it is drilled by a drill gun. When some gears are engaged with the intermittent gears, the roller frame and the lower roller are driven to rotate ninety degrees, and the upper pressure belt and the lower conveyor belt convey the metal pipe to one station, with a high degree of automation and good continuity; (2) The capping mechanism provided in the present invention inserts the cover module into both ends of the metal pipe, so that the metal pipe will not rotate autonomously during the conveying process, and can automatically flip and adjust the drilling position under the action of the self-rotating rack, 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.

[0042] The metal pipe to be drilled is placed in the feed shell 101, and the rotation of the partial gear 105 drives the semi-friction wheel 210 to rotate, thereby driving the docking friction wheel 212 to rotate intermittently, and the docking friction wheel 212 drives the top arc block 205 to slide back and forth through the inner rotating rod 213, and the top arc block 205 drives the inclined slide 202 to slide along the feed shell 101 through the sliding frame 204 and the sliding guide frame 203. Each time the inclined slide 202 goes back and forth, the metal pipe in the feed shell 101 falls into the lower space of the feed shell 101, and then the pipe enters the pipe groove of the upper roller 108. The inclined slide 202 is tilted to be able to move the remaining pipes when the inclined slide 202 rises. Push up, the upper roller 108 and the lower roller 121 rotate synchronously, when the pipe enters the pipe groove of the upper roller 108, after the pipe groove reaches the bottom, the pipe falls into the pipe groove of the lower roller 121, and the lower roller 121 continues to rotate with the pipe. When the pipe reaches the front of the inner push block 208, part of the gear 105 is disengaged from the intermittent gear 122.

[0043] When the upper pressing belt 112 and the lower conveying belt 119 are conveying the metal pipe, the clamping block 216 is limited by the upper notch 113 and the lower notch 120 , so that the metal pipe will not rotate autonomously during the conveying process.

[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 feed shell 101 is compressed. When the jacking arc block 205 slides along the feed shell 101, the spring resets and cooperates with the gravity of the lifting frame 301 to drive the drilling seat 303 and the drill gun 304 to descend, and the metal pipe is drilled by the drill gun 304. When the metal pipe is conveyed, the self-rotating gear 218 will contact the self-rotating rack 305. Under the action of the self-rotating rack 305, the self-rotating gear 218 and the metal pipe are driven to rotate ninety degrees to realize drilling on different surfaces of the metal pipe. When the metal pipe and the plug body 214 rotate, the block 216 slides relative to the plug body 214, and the block spring 217 is compressed and then rebounds.

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

[0048] The working principle of the metal pipe drilling equipment disclosed in the present invention is as follows: the metal pipe to be drilled is placed in the feed shell 101, the top motor 103 drives the motor gear 104 to rotate, and the vertical transmission belt 106 drives the transmission wheel 109 and the partial gear 105 to rotate, and the partial gear 105 drives the intermittent gear 122 to rotate intermittently, and 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, and the intermittent gear 122 drives the lower drum gear 124 to rotate through the horizontal transmission belt 123, thereby driving the lower drum 121, the lower drum gear 124 and The lower synchronous wheel 126 rotates, driving 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 oblique transmission belt 116, thereby driving the lower conveyor belt 119 to rotate. The rotation directions of the lower conveyor belt 119 and the upper compression belt 112 are opposite. Each time the partial 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 turn. The lower conveyor belt 119 and the intermittent gear 122 transport the metal pipe to one station through the upper notch 113 and the lower notch 120. The metal pipe to be drilled is placed in the feed shell 101, and the rotation of the partial gear 105 drives the semi-friction wheel 210 to rotate, thereby driving the docking friction wheel 212 to rotate intermittently, and the docking friction wheel 212 drives the top arc block 205 to slide back and forth through the inner rotating rod 213, and the top arc block 205 drives the inclined slide 202 to slide along the feed shell 101 through the sliding frame 204 and the sliding guide frame 203. Each time the inclined slide 202 goes back and forth, the metal pipe in the feed shell 101 falls into the lower space of the feed shell 101, and then the pipe enters the pipe groove of the upper roller 108. The inclined slide 202 is tilted to be able to move the remaining pipes when the inclined slide 202 rises. Push up, the upper roller 108 and the lower roller 121 rotate synchronously, when the pipe enters the pipe groove of the upper roller 108, after the pipe groove reaches the bottom, the pipe falls into the pipe groove of the lower roller 121, and the lower roller 121 continues to rotate with the pipe. When the pipe reaches the front of the inner push block 208, part of the gear 105 is disengaged from the intermittent gear 122. When the arc block 205 moves, it will also drive the outer long rotating rod 206 and the inner pressure rod 207 to rotate, and the inner pressure rod 207 pushes the inner push block 208 to slide inward, the inner spring 209 is stretched, and the plug 215 is pressed into the end of the metal pipe through the inner push block 208, so that the two ends of the metal pipe are covered.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 feed shell 101 is compressed. When the jacking arc block 205 slides along the feed shell 101, the spring resets and cooperates with the gravity of the lifting frame 301 to drive the drilling seat 303 and the drill gun 304 to descend, and the metal pipe is drilled by the drill gun 304. When the metal pipe is conveyed, the self-rotating gear 218 will contact the self-rotating rack 305. Under the action of the self-rotating rack 305, the self-rotating gear 218 and the metal pipe are driven to rotate ninety degrees to realize drilling on different surfaces of the metal pipe. When the metal pipe and the plug body 214 rotate, the block 216 slides relative to the plug body 214, and the block spring 217 is compressed and then rebounds.

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