Description

Technical Field

[0001] The present invention relates to the technical field of turning processing, and particularly relates to a turning processing device for multi-type corrugated pipes. Background Art

[0002] A corrugated pipe is a pipe with a corrugated shape, usually made of materials such as metal, plastic or rubber, and has certain flexibility and deformability. Its structural design enables it to maintain a certain elasticity and anti-deformation ability under pressure, temperature changes or external impacts, so it is widely used in fields that require pressure resistance, corrosion resistance, wear resistance, etc. The corrugated pipe can be extended or compressed within a certain range, enabling it to adapt to the vibration, displacement or temperature changes of the equipment. Before use, the corrugated pipe needs to be turned into a specified length for easy use. The corrugated pipe turning processing devices in the prior art usually cannot achieve the full-automatic positioning and cutting of the corrugated pipe, and there are many power sources and the control system is complex. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a turning processing device for multi-type corrugated pipes, including a clamping mechanism for clamping the corrugated pipe. The clamping mechanism includes a base. A tightening mechanism for tightening the corrugated pipe and a turning mechanism for turning the corrugated pipe are arranged on the clamping mechanism. The tightening mechanism includes an airbag, and the airbag is rotatably installed on the base. The turning mechanism includes a rotating disk, and the rotating disk is rotatably installed on the base. A torsion spring is arranged between the rotating disk and the base. The clamping mechanism includes a sliding lead screw and a sliding clamping frame. A connecting rod is fixedly installed on the sliding lead screw, and a rotating column is fixedly installed on the sliding clamping frame.

[0004] Further, the clamping mechanism further includes a motor fixedly installed on the base. A driving rotating rod is fixedly installed on the motor shaft of the motor. A driven rotating rod is rotatably installed on the driving rotating rod. A sliding groove is arranged on the base. A slider is slidably installed in the sliding groove. The slider is rotatably installed with the driven rotating rod. A connecting column is fixedly installed on the slider. A guide post is fixedly installed on the slider, and the guide post slides in the sliding groove.

[0005] Further, a docking ring is fixedly installed on the connecting column. A docking arc slope block is fixedly installed on the docking ring. A slope is arranged on the docking arc slope block. The docking ring is fixedly installed with the sliding lead screw. The sliding clamping frame is slidably installed with the sliding lead screw. A strong spring is arranged between the sliding clamping frame and the docking ring.

[0006] Further, a clamping frame is fixedly installed on the sliding clamping frame. Two clamping plates are slidably installed on the clamping frame. A clamping spring is arranged between the clamping plates and the clamping frame. Two fixing pieces are fixedly installed on the clamping frame.

[0007] When in use, the end of the corrugated pipe is clamped between the fixed piece and the clamping plate and clamped by the clamping spring. The motor drives the active rotating rod to rotate, thereby driving the passive rotating rod to rotate, thereby driving the slider and the guide post to slide along the chute, thereby driving the connecting column and the docking ring to move. The docking ring drives the sliding lead screw and the docking arc slope block to move together towards the internal thread gear. The strong spring pulls the sliding clamping frame and the clamping frame to move together, so that the clamping frame drives the corrugated pipe to reach the outside of the airbag.

[0008] Further, the tightening mechanism includes an airbag gear fixedly installed on the airbag. An internal thread gear is rotatably installed on the base. An internal thread is provided on the internal thread gear. The internal thread gear forms a screw drive with the sliding lead screw. The airbag gear meshes with the internal thread gear. A follower lead screw is fixedly installed on the connecting rod.

[0009] Further, a fan frame is fixedly installed on the base. A fan is rotatably installed on the fan frame. An internal thread is provided on the fan. The fan forms a screw drive with the follower lead screw.

[0010] As the sliding lead screw moves towards the internal thread gear, it will drive the follower lead screw to move together through the connecting rod. The follower lead screw drives the fan to rotate and inflate the airbag. After inflating for a period of time, the airbag contacts the inner wall of the corrugated pipe. At the same time, the sliding lead screw drives the internal thread gear to rotate. The internal thread gear drives the airbag gear and the airbag to rotate. After the airbag contacts the inner wall of the corrugated pipe, it drives the corrugated pipe to rotate synchronously.

[0011] Further, the turning mechanism includes a passive arc slope block fixedly installed on the rotating disk. A blocking rod is fixedly installed on the base. A rotating shaft is rotatably installed on the base. An upper transmission wheel is fixedly installed on the rotating shaft. An inclined transmission belt is wound around the upper transmission wheel and the rotating disk. An upper wheel is fixedly installed on the rotating shaft.

[0012] Further, a tool rest is rotatably installed on the rotating shaft. A turning tool is rotatably installed on the tool rest. A turning wheel is fixedly installed on the turning tool. A transmission belt is wound around the turning wheel and the upper wheel. A reset spring is provided between the tool rest and the base. An upper rotating block is rotatably installed below the tool rest. A pulling rotating block is rotatably installed on the rotating column. A pulling spring is provided between the pulling rotating block and the upper rotating block.

[0013] When the docking ring drives the sliding clamping frame to the blocking rod through the strong spring, the blocking rod blocks the sliding clamping frame from moving further. At this time, the clamping frame and the corrugated pipe no longer move, realizing the positioning of the corrugated pipe turning operation. When the sliding clamping frame moves, the tool holder is pulled to rotate around the rotating shaft by pulling the rotating block, the pulling spring and the upper rotating block. The return spring is compressed, so that the turning tool contacts the corrugated pipe. After the sliding clamping frame is blocked by the blocking rod, the docking ring continues to move. At this time, the sliding clamping frame slides along the sliding lead screw. After the docking arc slope block contacts the passive arc slope block, the docking arc slope block pushes the passive arc slope block and the rotating disk to rotate. The torsion spring between the rotating disk and the base is twisted. The upper transmission wheel, the rotating shaft and the upper wheel are driven to rotate through the inclined transmission belt. The turning wheel and the turning tool are driven to rotate slightly through the transmission belt, and the rotation of the corrugated pipe is driven in cooperation with the airbag. The corrugated pipe is turned by the turning tool. The position of the tool holder can be changed, and different models of corrugated pipes can be processed by replacing the pulling spring.

[0014] After the connecting column and the docking ring move to the farthest position, the motor continues to rotate, causing the connecting column, the docking ring and the sliding lead screw to start moving back. The gas in the airbag is pumped out, and at the same time, the return spring rebounds, cooperating with the torsion of the torsion spring between the rotating disk and the base, so that the rotating disk, the tool holder and the turning tool are reset.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The clamping mechanism provided by the present invention can initially position and clamp the end of the corrugated pipe, drive the corrugated pipe to move, and finally tighten the corrugated pipe through the tightening mechanism and drive the corrugated pipe to rotate self, which is convenient for turning processing; (2) When the docking ring drives the sliding clamping frame to the blocking rod through the strong spring, the blocking rod blocks the sliding clamping frame from moving further. At this time, the clamping frame and the corrugated pipe no longer move, realizing the positioning of the corrugated pipe turning operation. When the sliding clamping frame moves, the turning tool contacts the corrugated pipe. After the sliding clamping frame is blocked by the blocking rod, the docking ring continues to move, the turning wheel and the turning tool rotate slightly, and the rotation of the corrugated pipe is driven in cooperation with the airbag. The corrugated pipe is turned by the turning tool, with high automation; (3) The motor provided by the present invention first drives the corrugated pipe to move, and then drives the tightening mechanism to tighten the inner wall of the corrugated pipe and drive the corrugated pipe to rotate self. Then, after reaching the designated position, the corrugated pipe no longer moves and only rotates self, and the turning tool realizes self-positioning and automatic cutting, with good continuity.

[0028] As Figures 2 - 4 shown, the clamping mechanism further includes a motor 103 fixedly installed on the base 101.

[0029] As Figures 2 - 4 shown, a docking ring 109 is fixedly installed on the connecting column 108. A docking arc slope block 110 is fixedly installed on the docking ring 109. A slope is arranged on the docking arc slope block 110. The docking ring 109 is fixedly installed with the sliding lead screw 111. The sliding clamping frame 114 is slidably installed with the sliding lead screw 111. A strong spring 112 is arranged between the sliding clamping frame 114 and the docking ring 109.

[0030] As Figures 2 - 4 shown, a clamping frame 115 is fixedly installed on the sliding clamping frame 114. Two clamping plates 116 are slidably installed on the clamping frame 115. A clamping spring 117 is arranged between the clamping plates 116 and the clamping frame 115. Two fixing pieces 119 are fixedly installed on the clamping frame 115.

[0031] During use, the end of the corrugated pipe is clamped between the fixing piece 119 and the clamping plate 116 and clamped by the clamping spring 117. The motor 103 drives the driving rotating rod 104 to rotate, thereby driving the driven rotating rod 105 to rotate, thereby driving the slider 106 and the guide post 107 to slide along the sliding groove 102, thereby driving the connecting column 108 and the docking ring 109 to move. The docking ring 109 drives the sliding lead screw 111 and the docking arc slope block 110 to move together towards the internal - thread gear 203. The sliding clamping frame 114 and the clamping frame 115 are pulled through the strong spring 112 to move together, so that the clamping frame 115 drives the corrugated pipe to reach the outside of the airbag 201.

[0032] As Figures 5 - 7 shown, the tightening mechanism includes an airbag gear 202 fixedly installed on the airbag 201. An internally threaded gear 203 is rotatably installed on the base 101. The internally threaded gear 203 is provided with internal threads. The internally threaded gear 203 forms a threaded drive with the sliding lead screw 111. The airbag gear 202 meshes with the internally threaded gear 203. A follower lead screw 204 is fixedly installed on the connecting rod 118.

[0033] As Figures 5 - 7 shown, a fan bracket 205 is fixedly installed on the base 101. A fan 206 is rotatably installed on the fan bracket 205. The fan 206 is provided with internal threads. The fan 206 forms a threaded drive with the follower lead screw 204.

[0034] As the sliding lead screw 111 moves towards the internally threaded gear 203, it will drive the follower lead screw 204 to move together through the connecting rod 118. The follower lead screw 204 drives the fan 206 to rotate, blowing air into the airbag 201. After blowing air for a period of time, the airbag 201 contacts the inner wall of the bellows. At the same time, the sliding lead screw 111 drives the internally threaded gear 203 to rotate. The internally threaded gear 203 drives the airbag gear 202 and the airbag 201 to rotate. After the airbag 201 contacts the inner wall of the bellows, it drives the bellows to rotate synchronously.

[0035] As Figure 8 、 Figure 9 shown, the turning mechanism includes a passive arc slope block 302 fixedly installed on the rotating disk 301. A blocking rod 303 is fixedly installed on the base 101. A rotating shaft 305 is rotatably installed on the base 101. An upper transmission wheel 306 is fixedly installed on the rotating shaft 305. An inclined transmission belt 304 is wound around the upper transmission wheel 306 and the rotating disk 301. An upper wheel 307 is fixedly installed on the rotating shaft 305.

[0036] As Figure 8 、 Figure 9 shown, a tool holder 308 is rotatably installed on the rotating shaft 305. A turning tool 310 is rotatably installed on the tool holder 308. A turning wheel 311 is fixedly installed on the turning tool 310. A transmission belt 309 is wound around the turning wheel 311 and the upper wheel 307. A return spring 315 is provided between the tool holder 308 and the base 101. An upper rotating block 314 is rotatably installed below the tool holder 308. A pulling rotating block 312 is rotatably installed on the rotating column 113. A pulling spring 313 is provided between the pulling rotating block 312 and the upper rotating block 314.

[0037] When the docking ring 109 drives the sliding clamping bracket 114 to the blocking rod 303 through the strong spring 112, the blocking rod 303 blocks the continuous movement of the sliding clamping bracket 114. At this time, the clamping frame 115 and the corrugated pipe stop moving, realizing the positioning of the corrugated pipe turning operation. When the sliding clamping bracket 114 moves, the tool rest 308 is pulled to rotate around the rotating shaft 305 by pulling the rotating block 312, the pulling spring 313 and the upper rotating block 314, and the return spring 315 is compressed, so that the turning tool 310 contacts the corrugated pipe. After the sliding clamping bracket 114 is blocked by the blocking rod 303, the docking ring 109 continues to move. At this time, the sliding clamping bracket 114 slides along the sliding lead screw 111. After the docking arc slope block 110 contacts the passive arc slope block 302, the docking arc slope block 110 pushes the passive arc slope block 302 and the rotating disk 301 to rotate, and the torsion spring between the rotating disk 301 and the base 101 is twisted. The upper transmission wheel 306, the rotating shaft 305 and the upper wheel 307 are driven to rotate through the inclined transmission belt 304, and the turning wheel 311 and the turning tool 310 are driven to rotate slightly through the transmission belt 309, and the rotation of the corrugated pipe is driven in cooperation with the air bag 201. The corrugated pipe is machined by the turning tool 310. The position of the tool rest 308 can be changed, and different types of corrugated pipes can be processed by replacing the pulling spring 313.

[0038] When the connecting column 108 and the docking ring 109 move to the farthest position, the motor 103 continues to rotate, causing the connecting column 108, the docking ring 109 and the sliding lead screw 111 to start moving back. The gas in the air bag 201 is pumped out, and at the same time, the return spring 315 rebounds, and in cooperation with the torsion of the torsion spring between the rotating disk 301 and the base 101, the rotating disk 301, the tool rest 308 and the turning tool 310 are reset.

[0039] The working principle of a turning processing device for multi - model bellows disclosed by the present invention is as follows: When in use, the end of the bellows is clamped between the fixed piece 119 and the clamping plate 116 and clamped by the clamping spring 117. The motor 103 drives the active rotating rod 104 to rotate, thereby driving the passive rotating rod 105 to rotate, which drives the slider 106 and the guide post 107 to slide along the sliding groove 102, and then drives the connecting column 108 and the docking ring 109 to move. The docking ring 109 drives the sliding screw rod 111 and the docking arc slope block 110 to move together towards the internal thread gear 203. The sliding clamping frame 114 and the clamping frame 115 are pulled by the strong spring 112 to move, so that the clamping frame 115 drives the bellows to reach the outside of the airbag 201. As the sliding screw rod 111 moves towards the internal thread gear 203, it drives the follower screw rod 204 to move through the connecting rod 118. The follower screw rod 204 drives the fan 206 to rotate and inflate the airbag 201. After inflating for a period of time, the airbag 201 contacts the inner wall of the bellows. At the same time, the sliding screw rod 111 drives the internal thread gear 203 to rotate, and the internal thread gear 203 drives the airbag gear 202 and the airbag 201 to rotate. After the airbag 201 contacts the inner wall of the bellows, it drives the bellows to rotate synchronously. When the docking ring 109 drives the sliding clamping frame 114 to the blocking rod 303 through the strong spring 112, the blocking rod 303 blocks the sliding clamping frame 114 from continuing to move. At this time, the clamping frame 115 and the bellows stop moving, realizing the positioning of the bellows turning operation. When the sliding clamping frame 114 moves, the tool rest 308 is pulled to rotate around the rotating shaft 305 by pulling the rotating block 312, the pulling spring 313 and the upper rotating block 314, and the reset spring 315 is compressed, so that the turning tool 310 contacts the bellows. After the sliding clamping frame 114 is blocked by the blocking rod 303, the docking ring 109 continues to move. At this time, the sliding clamping frame 114 slides along the sliding screw rod 111. After the docking arc slope block 110 contacts the passive arc slope block 302, the docking arc slope block 110 pushes the passive arc slope block 302 and the rotating disk 301 to rotate. The torsion spring between the rotating disk 301 and the base 101 is twisted, and the upper transmission wheel 306, the rotating shaft 305 and the upper wheel 307 are driven to rotate through the inclined transmission belt 304. The turning wheel 311 and the turning tool 310 are driven to rotate slightly through the transmission belt 309, and cooperate with the rotation of the bellows driven by the airbag 201 to perform turning processing on the bellows with the turning tool 310. The position of the tool rest 308 can be changed, and different models of bellows can be processed by replacing the pulling spring 313.

[0040] 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, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
