For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] Reference Figures 1 to 8 The present invention provides a flexible shaft shrinking and fusing integrated device, comprising a base 1, a feeding mechanism 2, a shrinking mechanism 3 and a fusing mechanism 4. The base 1 is the foundation of the device and is placed on the ground or a work platform. The feeding mechanism 2, the shrinking mechanism 3 and the fusing mechanism 4 are sequentially connected to the base 1 along the travel direction of the flexible shaft. The discharge end of the feeding mechanism 2 is connected to the feed end of the shrinking mechanism 3, and the discharge end of the shrinking mechanism 3 is connected to the feed end of the fusing mechanism 4.

[0038] The feeding mechanism 2 can feed flexible shafts of different sizes, the shrinking mechanism 3 can shrink the flexible shafts, and the fusing mechanism 4 can fuse the flexible shafts. The feeding mechanism 2, the shrinking mechanism 3 and the fusing mechanism 4 cooperate with each other, and the equipment can realize fully automatic production and manufacturing. It can automatically feed, shrink and fuse a whole long flexible shaft, and cut the flexible shaft into flexible shafts of specified length for subsequent use. Compared with traditional manufacturing processes, the equipment can greatly reduce labor costs, and the manufactured flexible shafts are more refined, which greatly improves the working speed of flexible shaft processing and improves work efficiency.

[0039] As an optional implementation, the loading mechanism 2 includes a loading base plate 21, a support and limit assembly 22 and a support and drive assembly 23. The loading base plate 21 is connected to the base 1. The support and limit assembly 22 and the support and drive assembly 23 are sequentially connected to the loading base plate 21 along the travel direction of the flexible shaft. The flexible shaft can pass through the support and limit assembly 22 and the support and drive assembly 23 in sequence. The support and limit assembly 22 can support and limit the flexible shaft. The support and drive assembly 23 can drive the flexible shaft to move while supporting the flexible shaft.

[0040] Specifically, the support and limiting assembly 22 includes a loading plate 221, a transverse feeding rod 222 and a longitudinal feeding rod 223, and the bottom of the loading plate 221 is connected to the loading bottom plate 21;

[0041] The top of the loading plate 221 is provided with a loading trough with an opening upward, and the two ends of the transverse feeding rod 222 are rotatably connected to the two walls of the loading trough, and the two transverse feeding rods 222 are arranged in parallel and located in the same vertical plane, and the flexible shaft can pass through between the two transverse feeding rods 222;

[0042] The longitudinal feed rod 223 is rotatably connected to the loading bottom plate 21. The two longitudinal feed rods 223 are arranged in parallel and are located on the left and right sides of the flexible shaft's travel direction. After the flexible shaft passes through between the two transverse feed rods 222, it can pass through between the two longitudinal feed rods 223.

[0043] In this embodiment, the top end of the longitudinal feed rod 223 is preferably not lower than the top end of the transverse feed rod 222 located above. Such an arrangement can further ensure the support and limit of the flexible shaft.

[0044] Specifically, the support driving assembly 23 includes a feed support plate 231, a feed slide plate 232, a lifting handle 233, a lower pressing wheel 234, a support wheel 235, a connecting gear 236, a driving gear 237, a driven gear 238 and a feeding motor 239;

[0045] The feed support plate 231 is connected to the loading bottom plate 21. Three transmission grooves are provided on the feed support plate 231 along the travel direction of the flexible shaft. A feed slide plate 232 is movably connected to each transmission groove. A lifting handle 233 is movably connected to the top of each feed slide plate 232. The lifting handle 233 is movably connected to the feed support plate 231. The lifting handle 233 is threadedly connected to the feed slide plate 232 and the feed support plate 231. Rotating the lifting handle 233 can drive the feed slide plate 232 to move vertically inside the transmission groove.

[0046] One side of each feed slide 232 is movably connected to a lower pressing wheel 234 and the three lower pressing wheels 234 are located on the same side, and the lower pressing wheel 234 can move synchronously with the feed slide 232;

[0047] The feed support plate 231 is movably connected with three first transmission shafts 2311 and two second transmission shafts 2312 along the travel direction of the flexible shaft. The three first transmission shafts 2311 and the two second transmission shafts 2312 are alternately distributed in sequence. The two ends of the first transmission shaft 2311 respectively pass through the feed support plate 231. One end of each first transmission shaft 2311 close to the lower pressure wheel 234 is connected to a support wheel 235 and the other end is connected to a connecting gear 236. There is a lower pressure wheel 234 corresponding to the top, and the two second transmission shafts 2312 extend out from the feed support plate 231 at one end away from the lower pressure wheel 234. One of the second transmission shafts 2312 is connected to a driving gear 237, and the other second transmission shaft 2312 is connected to a driven gear 238. The connecting gear 236, the driving gear 237, and the driven gear 238 are meshed and connected. The feeding motor 239 is connected to the feed support plate 231 and its output shaft is connected to the driving gear 237.

[0048] The application principle of the feeding mechanism 2 in the actual application process is as follows: the feeding flexible shaft enters the device from the support limit assembly 22, first passes between the two transverse feeding rods 222, then passes between the two longitudinal feeding rods 223, and then enters between the lower pressing wheel 234 and the supporting wheel 235;

[0049] Manually adjust the lifting handle 233 to drive the feed slide 232 and the lower pressing wheel 234 to move vertically to a suitable position, and enable the lower pressing wheel 234 to press the flexible shaft;

[0050] The feeding motor 239 is started, which can drive the driving gear 237 to rotate. The driving gear 237 can drive the driven gear 238 and all the connecting gears 236 to rotate synchronously. The connecting gear 236 can drive the supporting wheel 235 to rotate.

[0051] Since the support wheel 235 is in a rotating state, the lower pressing wheel 234 and the support wheel 235 together squeeze the flexible shaft, so that the flexible shaft can follow the rotating support wheel 235 to move toward the shrinking mechanism 3, thereby realizing the mobile feeding of the flexible shaft;

[0052] Such a configuration can more effectively limit the position of the flexible shaft during the transmission process. At the same time, the above structure can make the feeding process more stable and avoid vibration, thereby ensuring the smooth progress of subsequent shrinking operations and fusing operations.

[0053] In addition, it is worth noting that since the position and height of the lower pressure wheel 234 can be adjusted, when facing flexible shafts of different sizes, the height of the lower pressure wheel 234 can be adjusted to correspond to the size of the flexible shaft, thereby expanding the scope of application and being able to adapt to flexible shafts of different sizes.

[0054] As an optional implementation, the shrinking mechanism 3 includes a shrinking seat 31 , a hydraulic cylinder 32 , a guide tube 33 , a connecting shaft 34 , a shrinking ring 35 and a shrinking pressure block 36 .

[0055] The necking seat 31 is connected to the base 1, the hydraulic cylinder 32 is connected to the necking seat 31 and the interior of the hydraulic cylinder 32 is a hollow structure, the hydraulic cylinder 32 is connected to one end of the guide tube 33 near the feeding mechanism 2, and the other end of the guide tube 33 is connected to the feeding mechanism 2, and the soft shaft transported by the feeding mechanism 2 can extend into the interior of the guide tube 33 from this end.

[0056] One end of the hydraulic cylinder 32 away from the feeding mechanism 2 is connected to a plurality of connecting shafts 34 along the circumferential direction, and the other end of the connecting shaft 34 is connected to the shrinking ring 35;

[0057] A shrinking cavity is provided on the shrinking ring 35 along the travel direction of the flexible shaft. The shrinking cavity is preferably in a truncated cone shape. Four shrinking pressure blocks 36 are slidably connected to the shrinking cavity and are drivingly connected to the hydraulic cylinder 32. After the hydraulic cylinder 32 is started, it can drive the four shrinking pressure blocks 36 to move relative to each other inside the shrinking cavity.

[0058] The centers of the four shrinking blocks 36 are together enclosed to form a shrinking portion. In this embodiment, the right-angled side of each shrinking block 36 close to the enclosed center is cut to form a 45° bevel, and the centers of the four shrinking blocks 36 are together enclosed to form a square shrinking portion.

[0059] The application principle of the shrinking mechanism 3 in the actual application process is as follows: the flexible shaft delivered by the feeding mechanism 2 is guided by the guide tube 33 and then passes through the hydraulic cylinder 32 to enter the shrinking cavity. The centers of the four shrinking pressure blocks 36 are enclosed and spliced ​​to form a square and surround the flexible shaft. When the flexible shaft moves to the specified position, the hydraulic cylinder 32 is started to drive the four shrinking pressure blocks 36 to move toward the fuse mechanism 4, so that the four shrinking pressure blocks 36 are close to each other at the same time, and the flexible shaft located in the four shrinking pressure blocks 36 is continuously squeezed. Finally, the squeezed part of the flexible shaft can form a square, and then the hydraulic cylinder 32 moves in the opposite direction to reset, driving the shrinking pressure blocks 36 to move and reset;

[0060] Such an arrangement can more effectively perform a shrinking process on the flexible shaft, change the shape of the portion of the flexible shaft to be cut in advance, and enable the fusing operation of the fusing mechanism 4 to proceed smoothly.

[0061] As an optional implementation, the fuse mechanism 4 includes a fuse bracket 41 , a fuse seat 42 , a moving assembly 43 , a clamping assembly 44 , a clamping block 45 and a fuse block 46 .

[0062] The fuse bracket 41 is connected to the base 1, and a fuse cavity is opened through the fuse bracket 41. Two fuse seats 42 are located inside the fuse cavity. The moving component 43 is connected to the fuse bracket 41. The fuse seat 42 close to the feeding mechanism 2 is fixedly connected to the fuse bracket 41, and the fuse seat 42 always remains relatively stationary. The fuse seat 42 away from the feeding mechanism 2 is connected to the moving component 43, and the moving component 43 can drive the corresponding fuse seat 42 to move relative to the other fuse seat 42.

[0063] In this embodiment, the moving component 43 preferably includes a separation cylinder, which is connected to the fuse bracket 41 and is driven and connected to the fuse seat 42 away from the feeding mechanism 2. After the separation cylinder is started, it can drive the fuse seat 42 to move. At the same time, a sliding structure composed of a slider and a slideway is preferably provided between the fuse seat 42 and the fuse cavity to assist the movement of the fuse seat 42.

[0064] Each fuse seat 42 is connected to a clamping assembly 44 and a clamping block 45, and one end of each clamping assembly 44 close to the clamping block 45 is connected to a fuse block 46. In this embodiment, the clamping assembly 44 preferably includes a clamping cylinder 441 and a fuse push block 442. The clamping cylinder 441 is connected to the fuse seat 42, and the fuse push block 442 is connected to the clamping cylinder 441 and connected to the fuse block 46. After the clamping cylinder 441 is started, it can drive the fuse push block 442 and the fuse block 46 to move synchronously relative to the clamping block 45.

[0065] The fuse block 46 is connected to an external power source, and the external power source can control the fuse block 46 to discharge, thereby achieving rapid fusing.

[0066] The application principle of the fuse mechanism 4 in the actual application process is: when the flexible shaft moves from the discharge end of the necking mechanism 3 to the relative position of the fuse mechanism 4, the flexible shaft can just be located between the fuse block 46 and the clamping block 45;

[0067] When the flexible shaft reaches the appropriate position, the clamping cylinder 441 is pushed out, thereby driving the fuse push block 442 and the fuse block 46 to move toward the clamping block 45, thereby clamping the conveyed flexible shaft, and then the external power supply is discharged, and the flexible shaft is melted through the fuse block 46. At the same time, due to the high temperature, the remaining filaments at the melt position can be burned;

[0068] After the fusing is completed, the separation cylinder of the moving assembly 43 contracts, driving the fuse seat 42 away from the shrinking mechanism 3 and the structure connected thereto to move in a direction away from another fuse seat 42, separating the fusing flexible shaft, and then the clamping cylinder 441 contracts and resets, at which time the fusing flexible shaft can be taken out, and then the separation cylinder extends, and the device is reset;

[0069] By adopting the above method, the flexible shaft can be cut more effectively, and the cut portion of the flexible shaft can also be processed more completely.

[0070] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
