Technical Field
[0001] This invention relates to the field of turning technology, and in particular to a multi-model bellows turning apparatus. Background Technology
[0002] A corrugated pipe is a type of pipe with a corrugated shape, typically made of materials such as metal, plastic, or rubber, possessing a degree of flexibility and deformability. Its structural design allows it to maintain elasticity and resistance to deformation under pressure, temperature changes, or external impacts, making it widely used in environments requiring pressure resistance, corrosion resistance, and wear resistance. Corrugated pipes can elongate or compress within a certain range, enabling them to adapt to equipment vibration, displacement, or temperature changes. Before use, corrugated pipes need to be machined to a specified length. Existing corrugated pipe machining equipment typically cannot achieve fully automated positioning and cutting, and it suffers from numerous power sources and complex control systems. Summary of the Invention
[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a multi-model corrugated pipe turning processing device, comprising a clamping mechanism for clamping the corrugated pipe, the clamping mechanism comprising a base, a tensioning mechanism for tightening the corrugated pipe and a turning mechanism for turning the corrugated pipe, the tensioning mechanism comprising an air bladder rotatably mounted on the base, the turning mechanism comprising a rotating disk rotatably mounted on the base, and a torsion spring disposed between the rotating disk and the base;
[0004] 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.
[0005] Furthermore, the clamping mechanism also includes a motor fixedly mounted on the base, an active rotating rod fixedly mounted on the motor shaft, a passive rotating rod rotatably mounted on the active rotating rod, a sliding groove provided on the base, a slider slidably mounted in the sliding groove, the slider and the passive rotating rod rotatably mounted, a connecting column fixedly mounted on the slider, and a guide column fixedly mounted on the slider, the guide column sliding in the sliding groove.
[0006] Furthermore, a docking ring is fixedly installed on the connecting column, a docking arc ramp is fixedly installed on the docking ring, a ramp surface is provided on the docking arc ramp, the docking ring is fixedly installed with the sliding screw, the sliding clamp is slidably installed with the sliding screw, and a strong spring is provided between the sliding clamp and the docking ring.
[0007] Furthermore, 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 provided between the clamping plates and the clamping frame, and two fixing plates are fixedly installed on the clamping frame.
[0008] In use, the end of the bellows is clamped between the fixed plate and the clamping plate, and clamped by the clamping spring. The motor drives the active rotating rod to rotate, which in turn drives the passive rotating rod to rotate, which in turn drives the slider and guide post to slide along the slide groove, thereby driving the connecting post and the docking ring to move. The docking ring drives the sliding screw and the docking arc slope block to move together toward the internal thread gear. The strong spring pulls the sliding clamping frame and the clamping frame to move together, so that the clamping frame carries the bellows to the outside of the airbag.
[0009] Furthermore, the tensioning mechanism includes an airbag gear fixedly mounted on the airbag, an internally threaded gear rotatably mounted on the base, the internally threaded gear having an internal thread, the internally threaded gear forming a threaded transmission with the sliding screw, the airbag gear meshing with the internally threaded gear, and a follower screw fixedly mounted on the connecting rod.
[0010] Furthermore, a fan bracket is fixedly installed on the base, and a fan is rotatably installed on the fan bracket. The fan has an internal thread, and the fan and the follower screw form a threaded transmission.
[0011] As the sliding lead screw moves toward the internal threaded gear, it drives the follower lead screw to move together via the connecting rod. The follower lead screw drives the fan to rotate, inflating the airbag. After inflating for a period of time, the airbag contacts the inner wall of the bellows. At the same time, the sliding lead screw drives the internal threaded gear to rotate, which in turn drives the airbag gear and the airbag to rotate. After the airbag contacts the inner wall of the bellows, it drives the bellows to rotate synchronously.
[0012] Furthermore, the turning mechanism includes a passive arc ramp block fixedly installed on the turntable, a blocking rod fixedly installed on the base, a rotating shaft rotatably installed on the base, an upper transmission wheel fixedly installed on the rotating shaft, an oblique transmission belt wound around the upper transmission wheel and the turntable, and an upper wheel fixedly installed on the rotating shaft.
[0013] Furthermore, a tool holder is rotatably mounted on the rotating shaft, a turning tool is rotatably mounted on the tool holder, a turning wheel is fixedly mounted on the turning tool, a transmission belt is wound around the turning wheel and the upper wheel, a return spring is provided between the tool holder and the base, an upper rotating block is rotatably mounted below the tool holder, a pulling rotating block is rotatably mounted on the rotating column, and a pulling spring is provided between the pulling rotating block and the upper rotating block.
[0014] When the mating ring is driven to the blocking bar by the strong spring, the blocking bar prevents the sliding clamping frame from moving further. At this time, the clamping frame and the bellows stop moving, thus achieving the positioning for the bellows turning operation. When the sliding clamping frame moves, the tool holder is pulled around the rotating shaft by pulling the rotating block, pulling the spring, and the upper rotating block. The return spring is compressed, causing the turning tool to contact the bellows. When the sliding clamping frame is blocked by the blocking bar, the mating ring continues to move. At this time, the sliding clamping frame slides along the sliding lead screw. After the mating arc slope block contacts the passive arc slope block, the mating 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, which drives the upper transmission wheel, the rotating shaft, and the upper wheel to rotate through the inclined transmission belt. The transmission belt drives the turning wheel and the turning tool to rotate slightly, and the air bag drives the bellows to rotate. The bellows is then turned by the turning tool. The position of the tool holder can be changed, and different types of bellows can be processed by changing the pulling spring.
[0015] When the connecting post and mating ring have moved to their furthest point, the motor continues to rotate, causing the connecting post, mating ring, and sliding screw to begin to move back. The gas in the airbag is extracted, and at the same time, the return spring rebounds. In conjunction with the torsion spring between the rotating disk and the base, the rotating disk, tool holder, and turning tool are reset.
[0016] The beneficial effects of this invention compared with the prior art are: (1) The clamping mechanism set in this invention can initially position and clamp the end of the bellows, and drive the bellows to move. Finally, the bellows is tightened by the tensioning mechanism and driven to rotate, which is convenient for turning; (2) When the connecting ring set in this invention drives the sliding clamping frame to the blocking rod by the strong spring, the blocking rod prevents the sliding clamping frame from moving further. At this time, the clamping frame and the bellows no longer move, realizing the positioning of the bellows turning operation. When the sliding clamping frame moves, This allows the turning tool to contact the bellows. When the sliding clamping frame is blocked by the blocking rod, the mating ring continues to move. The turning wheel and the turning tool rotate slightly, and the air bag drives the bellows to rotate. The bellows is machined by the turning tool, resulting in a high degree of automation. (3) The motor in this invention first drives the bellows to move, and then drives the tensioning mechanism to tension the inner wall of the bellows and drive the bellows to rotate. After reaching the designated position, the bellows no longer moves, but only rotates. The turning tool achieves self-positioning and automatic cutting, with good continuity.

Detailed Implementation
[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0028] Example: Reference Figures 1-9A multi-model corrugated pipe turning processing device includes a clamping mechanism for clamping the corrugated pipe. The clamping mechanism includes a base 101, a tensioning mechanism for tightening the corrugated pipe and a turning mechanism for turning the corrugated pipe. The tensioning mechanism includes an air bladder 201, which is rotatably mounted on the base 101. The turning mechanism includes a rotating disk 301, which is rotatably mounted on the base 101. A torsion spring is provided between the rotating disk 301 and the base 101.
[0029] The clamping mechanism includes a sliding lead screw 111 and a sliding clamping frame 114. A connecting rod 118 is fixedly installed on the sliding lead screw 111, and a rotating column 113 is fixedly installed on the sliding clamping frame 114.
[0030] like Figures 2-4 As shown, the clamping mechanism also includes a motor 103 fixedly mounted on the base 101. An active rotating rod 104 is fixedly mounted on the motor shaft of the motor 103. A passive rotating rod 105 is rotatably mounted on the active rotating rod 104. A sliding groove 102 is provided on the base 101. A slider 106 is slidably mounted in the sliding groove 102. The slider 106 is rotatably mounted with the passive rotating rod 105. A connecting post 108 is fixedly mounted on the slider 106. A guide post 107 is fixedly mounted on the slider 106. The guide post 107 slides in the sliding groove 102.
[0031] like Figures 2-4 As shown, a docking ring 109 is fixedly installed on the connecting column 108, and a docking arc ramp 110 is fixedly installed on the docking ring 109. The docking arc ramp 110 is provided with a slope. The docking ring 109 is fixedly installed with the sliding screw 111, and the sliding clamping frame 114 is slidably installed with the sliding screw 111. A strong spring 112 is provided between the sliding clamping frame 114 and the docking ring 109.
[0032] like Figures 2-4 As shown, a clamping frame 115 is fixedly installed on the sliding clamping frame 114, and two clamping plates 116 are slidably installed on the clamping frame 115. A clamping spring 117 is provided between the clamping plate 116 and the clamping frame 115, and two fixing pieces 119 are fixedly installed on the clamping frame 115.
[0033] In use, the end of the bellows is clamped between the fixing plate 119 and the clamping plate 116 and clamped by the clamping spring 117. The motor 103 drives the active rotating rod 104 to rotate, which in turn drives the passive rotating rod 105 to rotate, which in turn drives the slider 106 and the guide post 107 to slide along the slide groove 102, which in turn drives the connecting post 108 and the docking ring 109 to move. The docking ring 109 drives the sliding screw 111 and the docking arc slope block 110 to move together toward the internal thread gear 203. The strong spring 112 pulls the sliding clamping frame 114 and the clamping frame 115 to move together, so that the clamping frame 115 carries the bellows to the outside of the airbag 201.
[0034] like Figures 5-7 As shown, the tensioning mechanism includes an airbag gear 202 fixedly mounted on the airbag 201, an internal thread gear 203 rotatably mounted on the base 101, the internal thread gear 203 having an internal thread, the internal thread gear 203 forming a threaded transmission with the sliding screw 111, the airbag gear 202 meshing with the internal thread gear 203, and a follower screw 204 fixedly mounted on the connecting rod 118.
[0035] like Figures 5-7 As shown, a fan bracket 205 is fixedly installed on the base 101, and a fan 206 is rotatably installed on the fan bracket 205. The fan 206 is provided with an internal thread, and the fan 206 and the follower screw 204 form a threaded transmission.
[0036] As the sliding lead screw 111 moves toward the internal threaded gear 203, it drives the follower lead screw 204 to move together via the connecting rod 118. The follower lead screw 204 drives the fan 206 to rotate, inflating 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 lead screw 111 drives the internal threaded gear 203 to rotate, which in turn 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.
[0037] like Figure 8 , Figure 9 As shown, the turning mechanism includes a passive arc ramp block 302 fixedly installed on a rotating disk 301, a blocking rod 303 fixedly installed on a base 101, a rotating shaft 305 rotatably installed on the base 101, an upper transmission wheel 306 fixedly installed on the rotating shaft 305, an oblique transmission belt 304 wound around the upper transmission wheel 306 and the rotating disk 301, and an upper wheel 307 fixedly installed on the rotating shaft 305.
[0038] like Figure 8 , Figure 9 As shown, a tool holder 308 is rotatably mounted on the rotating shaft 305, a turning tool 310 is rotatably mounted on the tool holder 308, a turning wheel 311 is fixedly mounted 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 mounted below the tool holder 308, a pulling rotating block 312 is rotatably mounted on the rotating column 113, and a pulling spring 313 is provided between the pulling rotating block 312 and the upper rotating block 314.
[0039] When the mating ring 109 moves the sliding clamping frame 114 to the blocking rod 303 via the strong spring 112, the blocking rod 303 prevents the sliding clamping frame 114 from moving further. At this time, the clamping frame 115 and the bellows no longer move, achieving the positioning for the bellows turning operation. When the sliding clamping frame 114 moves, the tool holder 308 is pulled around the rotating shaft 305 by pulling the rotating block 312, pulling the spring 313, and the upper rotating block 314. The return spring 315 is compressed, causing the turning tool 310 to contact the bellows. When the sliding clamping frame 114 is blocked by the blocking rod 303, the mating ring 109 continues to move. At this time, the sliding clamping frame 114 moves along the sliding lead screw. After sliding, the mating arc ramp 110 contacts the passive arc ramp 302, and the mating arc ramp 110 pushes the passive arc ramp 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 the bellows is rotated in conjunction with the air bag 201. The bellows is turned by the turning tool 310. The position of the tool holder 308 can be changed, and the different models of bellows can be processed by changing the pull spring 313.
[0040] When the connecting post 108 and the mating ring 109 have moved to their furthest point, the motor 103 continues to rotate, causing the connecting post 108, the mating ring 109 and the sliding lead screw 111 to begin to move back. The gas in the airbag 201 is extracted, and at the same time the return spring 315 rebounds. In conjunction with the torsion spring between the rotating disk 301 and the base 101, the rotating disk 301, the tool holder 308 and the turning tool 310 are reset.
[0041] The working principle of the multi-model bellows turning processing device disclosed in this invention is as follows: In use, the end of the bellows is clamped between the fixed plate 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, thereby driving the slider 106 and the guide post 107 to slide along the slide groove 102, thereby driving the connecting post 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 toward the internal thread gear 203. The strong spring 112 pulls the sliding clamping frame 114 and the clamping frame 115 to move together, so that the clamping frame 115 carries the bellows to the outside of the airbag 201. As the sliding lead screw 111 moves toward the internal threaded gear 203, it drives the follower lead screw 204 to move together via the connecting rod 118. The follower lead screw 204 drives the fan 206 to rotate, inflating 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 lead screw 111 drives the internal threaded gear 203 to rotate, which in turn 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 mating ring 109 moves the sliding clamping frame 114 to the blocking rod 303 via the strong spring 112, the blocking rod 303 prevents the sliding clamping frame 114 from moving further. At this time, the clamping frame 115 and the bellows no longer move, achieving the positioning for the bellows turning operation. When the sliding clamping frame 114 moves, the tool holder 308 is pulled around the rotating shaft 305 by pulling the rotating block 312, pulling the spring 313, and the upper rotating block 314. The return spring 315 is compressed, causing the turning tool 310 to contact the bellows. When the sliding clamping frame 114 is blocked by the blocking rod 303, the mating ring 109 continues to move. At this time, the sliding clamping frame 114 moves along the sliding lead screw. After sliding, the mating arc ramp 110 contacts the passive arc ramp 302, and the mating arc ramp 110 pushes the passive arc ramp 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 the bellows is rotated in conjunction with the air bag 201. The bellows is turned by the turning tool 310. The position of the tool holder 308 can be changed, and the different models of bellows can be processed by changing the pull spring 313.
[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
