Description

Technical Field

[0001] This utility model relates to the field of winding device technology, specifically a nickel-titanium shape memory alloy wire winding device. Background Technology

[0002] Nickel-titanium shape memory alloys possess remarkable properties such as shape memory effect and superelasticity. The shape memory effect refers to the alloy's ability to automatically recover its original shape after plastic deformation under certain conditions and appropriate stimulation (such as heating or magnetic field). Superelasticity enables it to generate large recoverable strain when deformed under stress. These properties make it a promising candidate for applications in many fields such as medical devices, aerospace, automobile manufacturing, and robotics.

[0003] After the nickel-titanium shape memory alloy wire is produced, it is mainly wound into a ball by a winding device for easy storage and transportation. In order to make it evenly wound on the spool, the winding direction of the alloy wire is usually guided by guide wheels. In order to keep the alloy wire taut during the winding process and ensure the tightness and neatness of the winding, a spring is usually installed at the bottom of the guide wheel. The tension of the alloy wire is adjusted by the elasticity of the spring, so that the alloy wire can be wound more evenly on the spool.

[0004] However, because the spring force is relatively fixed, it can uniformly and well adjust the tension of alloy wire of a single specification. But when adjusting the tension of alloy wire of different specifications, the spring force cannot adapt to the new alloy wire specification in a timely and accurate manner. This results in the alloy wire tension not being well adjusted, which may cause the alloy wire to be too tight or too loose during winding. This may cause the alloy wire to be wound unevenly on the spool, resulting in excessive local stress concentration in the alloy wire. In the long-term use process, fatigue cracks are likely to occur, which will have a significant impact on the service life of the alloy wire. Utility Model Content

[0005] The purpose of this invention is to provide a nickel-titanium shape memory alloy wire winding device to solve the problem of untimely tension adjustment of alloy wires of different specifications mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A nickel-titanium shape memory alloy wire winding device includes: a main body with an adjusting block on it; an adjusting component on the adjusting block, comprising a lead screw on the adjusting block, a support rod on the lead screw, a bracket on the support rod, and a connecting shaft on the bracket; the adjusting component is used for tension adjustment of the nickel-titanium shape memory alloy wire; and a limiting component on the connecting shaft, comprising a guide wheel on the connecting shaft, a spring on the guide wheel, the limiting component being used for limiting the nickel-titanium shape memory alloy wire.

[0008] Preferably, the adjustment assembly further includes a motor disposed on one side of the adjustment block, the output end of the motor being fixedly connected to a lead screw, a threaded block being threadedly connected to the outer side of the lead screw, and a receiving groove being provided on the adjustment block corresponding to the threaded block, the threaded block being movably disposed in the receiving groove.

[0009] Preferably, a connecting rod is fixedly connected to one side of the threaded block, and two sets of T-shaped blocks are symmetrically fixedly connected to the side of the connecting rod that is engaged with the adjusting block. The adjusting block is provided with a T-shaped groove corresponding to the T-shaped block, and the T-shaped block is movably disposed in the T-shaped groove.

[0010] Preferably, the side of the support rod closest to the adjusting block is rotatably connected to the T-block, and one side of the support rod is rotatably connected to the bracket.

[0011] Preferably, a rotating shaft is fixedly connected to the support near the adjusting block, and the rotating shaft passes through the support, with both sides of the rotating shaft rotatably connected to the adjusting block.

[0012] Preferably, two sets of mounting plates are symmetrically fixedly connected to the inner side of the bracket. A sliding groove is provided on the side of the mounting plate near the connecting shaft. A slider is movably arranged inside the sliding groove. The connecting shaft and the slider are rotatably connected. An elastic element is provided between the slider and the sliding groove.

[0013] Preferably, the limiting component further includes a spring disposed on the outside of the connecting shaft, the spring being fixedly connected to the slider and rotatably connected to the guide wheel, and two sets of guide wheels being symmetrically and movably connected on the connecting shaft.

[0014] Preferably, multiple sets of rollers are evenly arranged on the side of the guide wheel away from the mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When it is necessary to wind up the nickel-titanium shape memory alloy wire, the alloy wire is wound several times around the connecting shaft between the two sets of guide wheels, and then wound onto the corresponding spool. The spool is then rotated to wind the alloy wire onto it. When the alloy wire becomes loose or tight, the rotation of the motor is controlled, which in turn drives the support rod to rotate through the movement of the threaded block. This, in turn, drives the bracket to rotate, which in turn moves the alloy wire up or down, thus keeping the alloy wire taut during the winding process. Then, by moving the adjusting block, the alloy wire can be evenly wound onto the spool.

[0017] The spring force drives two sets of guide wheels to move towards the alloy wire, thereby restricting the position of alloy wires of different specifications. This prevents the alloy wire from shifting during winding, ensuring that the alloy wire is stably wound on the spool. The rollers further increase the movement of the alloy wire, effectively preventing it from getting stuck. Attached Figure Description

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figure 1 - Figure 6 As shown, this application provides a nickel-titanium shape memory alloy wire winding device, including: a device body 1, an adjusting block 2 on the device body 1, and an adjusting component on the adjusting block 2. The adjusting component includes a lead screw 12 on the adjusting block 2, a support rod 7 on the lead screw 12, a bracket 4 on the support rod 7, and a connecting shaft 19 on the bracket 4. The adjusting component is used for tension adjustment of the nickel-titanium shape memory alloy wire.

[0028] Specifically, such as Figure 4 As shown, the adjustment assembly also includes a motor 5 disposed on one side of the adjustment block 2. The output end of the motor 5 is fixedly connected to the lead screw 12. A threaded block 11 is threadedly connected to the outer side of the lead screw 12. A receiving groove 14 is provided on the adjustment block 2 corresponding to the threaded block 11. The threaded block 11 is movably disposed in the receiving groove 14. By rotating the motor 5, the lead screw 12 can be driven to rotate stably, thereby driving the threaded block 11 to move within the receiving groove 14.

[0029] Specifically, such as Figure 4 As shown, a connecting rod 10 is fixedly connected to one side of the threaded block 11. Two sets of T-shaped blocks 9 are symmetrically fixedly connected to the side of the connecting rod 10 that is engaged with the adjusting block 2. A T-shaped groove 8 is provided on the adjusting block 2 corresponding to the T-shaped block 9. The T-shaped block 9 is movably disposed in the T-shaped groove 8. Through the cooperation between the T-shaped block 9 and the T-shaped groove 8, the rotation of the support rod 7 can be supported.

[0030] Specifically, such as Figure 4 As shown, the side of the support rod 7 closest to the adjusting block 2 is rotatably connected to the T-shaped block 9, and one side of the support rod 7 is rotatably connected to the bracket 4. The movement of the support rod 7 can drive the bracket 4 to rotate, thereby adjusting the tension of the alloy wire.

[0031] Specifically, such as Figure 3 As shown, a rotating shaft 6 is fixedly connected to the bracket 4 near the adjusting block 2, and the rotating shaft 6 passes through the bracket 4. Both sides of the rotating shaft 6 are rotatably connected to the adjusting block 2. Through the setting of the rotating shaft 6, the bracket 4 and the adjusting block 2 can be connected together.

[0032] Specifically, such as Figure 6 As shown, two sets of mounting plates 13 are symmetrically fixedly connected to the inner side of the bracket 4. A sliding groove 20 is provided on the side of the mounting plate 13 near the connecting shaft 19. A slider 17 is movably arranged inside the sliding groove 20. The connecting shaft 19 and the slider 17 are rotatably connected. An elastic element 18 is provided between the slider 17 and the sliding groove 20. The tension of the alloy wire can be initially adjusted by the elastic force of the elastic element 18.

[0033] A limiting component is provided on the connecting shaft 19. The limiting component includes a guide wheel 3 provided on the connecting shaft 19 and a spring 16 provided on the guide wheel 3. The limiting component is used to limit the nickel-titanium shape memory alloy wire.

[0034] Specifically, such as Figure 6 As shown, the limiting assembly also includes a spring 16 disposed on the outside of the connecting shaft 19. The spring 16 is fixedly connected to the slider 17 and rotatably connected to the guide wheel 3. Two sets of guide wheels 3 are symmetrically and movably connected on the connecting shaft 19. Through the cooperation of the two sets of guide wheels 3, the alloy wire can be limited.

[0035] Specifically, such as Figure 6 As shown, multiple sets of rollers 15 are evenly arranged on the side of the guide wheel 3 away from the mounting plate 13. The arrangement of the rollers 15 enables the movement of the alloy wire.

[0036] In this embodiment: the alloy wire is wound several times around the connecting shaft 19 between the two sets of guide wheels 3, and then wound onto the corresponding drum. The drum is then rotated to wind the alloy wire onto it. At this time, the rotation of the motor 5 is controlled, so the movement of the threaded block 11 drives the support rod 7 to rotate, which in turn drives the bracket 4 to rotate. This allows the alloy wire to move up or down, keeping it taut during winding. The elastic force of the spring 16 moves the two sets of guide wheels 3 toward the alloy wire, thus restricting the position of alloy wires of different specifications and effectively preventing displacement of the alloy wire during winding, ensuring that the alloy wire is stably wound onto the drum.

[0037] Specifically, this solution works as follows: When it is necessary to adjust the tension of the alloy wire, the alloy wire is wound around the connecting shaft 19, positioning it between the two sets of guide wheels 3. The elastic force of the spring 16 firmly restrains alloy wires of different specifications, preventing displacement during winding and ensuring stable winding on the spool. When the alloy wire becomes taut, it applies pressure to the connecting shaft 19, and the elastic force of the elastic element 18 initially counteracts this pressure, thus achieving initial adjustment of the alloy wire tension. When the tension becomes more severe... When the alloy wire is in a taut state, the rotation of the motor 5 is controlled, which drives the lead screw 12 to rotate. This causes the T-block 9 to slide in the T-groove 8 via the threaded block 11, which in turn drives the support rod 7 to move and thus the bracket 4 to rotate. This allows the overly taut alloy wire to be adjusted to a normal state. When the alloy wire becomes loose, the above operation is repeated in reverse. This facilitates the tension adjustment of the nickel-titanium shape memory alloy wire, allowing the alloy wire to be evenly wound on the spool and effectively preventing stress concentration during the winding process.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
