Description

Technical Field

[0001] The utility model belongs to the technical field of piano manufacturing, and particularly relates to a piano string winding device. Background Art

[0002] A piano is a common keyboard instrument, and the installation and tuning of its strings are one of the key steps to ensure its sound quality and pitch accuracy. During the production and maintenance of a piano, the string winding operation is a cumbersome and delicate process.

[0003] Traditional string winding methods mainly rely on manual operations. Workers need to manually hold the string and fix it in a specific position, and then complete the winding by mechanical or manual rotation. This method not only has low efficiency, but also requires high operation skills for workers. If not careful, it may cause damage to the string or loose winding, affecting the sound quality of the piano.

[0004] Although some existing automatic winding devices have improved the work efficiency to a certain extent, there are still the following problems:

[0005] 1. The fixation of the string during the winding process is not stable enough, which easily causes the position of the string to shift, resulting in uneven winding.

[0006] 2. During the winding process, the movement of the device is not stable enough, affecting the winding quality.

[0007] 3. It has poor adaptability to different specifications of strings, resulting in more debugging time required when changing the string specifications. Summary of the Utility Model

[0008] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a piano string winding device, which can improve the efficiency and quality of string winding, reduce the technical requirements for operators, and adapt to the winding requirements of different specifications of strings.

[0009] To achieve the above purpose, the utility model provides the following technical solutions:

[0010] A piano string winding device includes a tabletop. A winding table and a wire clamping assembly are arranged on the upper end surface of the tabletop. The wire clamping assemblies are arranged oppositely around the winding table and are distributed on both sides of the winding table;

[0011] During the process of winding the string, one end of the string is fixedly clamped between the two wire clamping assemblies;

[0012] One end of the winding table is provided with a pressing mechanism, and the pressing mechanism is used to press the string during the winding process;

[0013] A rotating mechanism is arranged on one side of the pressing mechanism;

[0014] The rotating mechanism includes a third cylinder. The telescopic end of the third cylinder is connected to a motor. The output end of the motor is connected to a rotating member. One side of the rotating member is fixedly connected with a wire hanging post.

[0015] During the winding of the string, one end of the string is hung on the wire hanging post.

[0016] Furthermore, the wire clamping assembly includes a first cylinder. The telescopic end of the first cylinder is connected to a mounting seat. One side of the mounting seat is connected with a clamping block.

[0017] When winding the string, the string is clamped between the two clamping blocks.

[0018] Furthermore, an embedding groove is formed on one side of the mounting seat. An embedding block is fixedly connected to the side of the clamping block. The embedding block and the embedding groove cooperate with each other.

[0019] Through holes are symmetrically formed through the top of the mounting seat.

[0020] A cover plate is connected to the top of one of the mounting seats.

[0021] Furthermore, the pressing mechanism includes a fixed rod installed on the tabletop. First guiding columns are symmetrically fixedly connected to the top of the fixed rod. Sliders are sleeved on the first guiding columns. An activity rod is connected between the inner sides of the two sliders.

[0022] When winding the string, the string to be wound is located between the activity rod and the fixed rod.

[0023] The outer sides of the sliders are connected with second cylinders.

[0024] Furthermore, a first connecting plate is fixedly connected to the inner sides of the sliders. The activity rod is connected to the first connecting plate through bolts.

[0025] A second connecting plate is fixedly connected to the outer sides of the sliders. One end of the second connecting plate is connected to the telescopic end of the second cylinder.

[0026] Furthermore, a wire insertion hole is formed through one end of the winding table.

[0027] Furthermore, a sliding table is connected to the bottom of the motor. Second guiding columns are arranged at the bottom of the sliding table. The sliding table is slidably connected with the second guiding columns.

[0028] Compared with the prior art, the beneficial effects of the utility model are:

[0029] By fixing and clamping one end of the string between two wire clamping components, the stability of the string during the winding process is ensured. The pressing mechanism arranged at one end of the winding table can press the string tightly during the winding process, preventing the problems of slack or displacement of the string during winding. Through the cooperation of the pressing mechanism and the rotating mechanism, precise winding of one end of the string can be achieved, improving the quality and efficiency of winding.

[0030] The rotating mechanism includes a third cylinder, a motor, a rotating part and a wire hanging post. The third cylinder is used to push the motor to move along the slide on the second guiding post, enabling the rotating part to operate smoothly during the winding process. The motor drives the rotating part to rotate, so that one end of the string hanging on the post is evenly wound, avoiding the problems of uneven winding and string damage that occur in the traditional manual winding process. The design of the slide and the guiding post further improves the smoothness of the motor movement, ensuring the stability of the winding process.

[0031] The wire clamping component realizes firm clamping of the string by the first cylinder pushing the mounting seat and the clamping block closer. The embedding groove on the mounting seat and the embedding block on the clamping block cooperate with each other, making the connection of the clamping block firm and facilitating disassembly, replacement and installation. The through hole and the cover plate on the top of the mounting seat not only protect the clamping block and the embedding block, but also ensure the reliability of the device. This design effectively solves the problem of unstable string fixation in traditional winding equipment, improving the adaptability of the device and the convenience of operation.

[0032] The pressing mechanism realizes extrusion and fixation of the double-strand part of the string during the winding process through the cooperation of a fixed rod, a first guiding post, a slider and a movable rod. The second cylinder pushes the slider to slide on the first guiding post, making the position of the string more stable during the winding process. The first connecting plate and the second connecting plate on the slider are connected by bolts and cylinders, ensuring the stability and reliability of the pressing mechanism. This design solves the problems of possible slack or displacement of the string during the winding process, improving the winding quality and operation efficiency. Description of the Drawings

[0047] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0048] Referring to Figures 1-6 , a piano string winding device includes a tabletop 1, and a winding table 11 and a wire clamping assembly 2 are arranged on the upper end surface of the tabletop 1; the wire clamping assemblies 2 are arranged opposite to each other around the winding table 11, and the wire clamping assemblies 2 are distributed on both sides of the winding table 11; during the process of winding the string, one end of the string is fixedly clamped between the two wire clamping assemblies 2; a pressing-down mechanism 3 is arranged at one end of the winding table 11, and the pressing-down mechanism 3 is used to press the string during the winding process; a rotating mechanism 4 is arranged on one side of the pressing-down mechanism 3; the rotating mechanism 4 includes a third cylinder 44, the telescopic end of the third cylinder 44 is connected to a motor 43, the output end of the motor 43 is connected to a rotating part 45, and a wire hanging post 46 is fixedly connected to the side surface of one end of the rotating part 45; during the process of winding the string, one end of the string is hung on the wire hanging post 46; the motor 43 moves along the slide table 42 on the second guiding column 41 under the push of the third cylinder 44, so that the rotating part 45 passes through between the fixed rod 31 and the movable rod 33; through this design, the moving process of the motor 43 is made more stable, ensuring the stability and uniformity of the string winding.

[0049] Refer to Figures 1-3 Figures 1-3 , the wire clamping assembly 2 includes a first cylinder 21. The telescopic end of the first cylinder 21 is connected with a mounting seat 22, and one side of the mounting seat 22 is connected with a clamping block 23. When winding the string, the string is clamped between the two clamping blocks 23. The first cylinder 21 pushes the mounting seat 22 and the clamping block 23 to move closer to each other, so as to firmly clamp the other end of the string. This design ensures the fixed position of the string during the winding process and avoids the problems of the string loosening or shifting.

[0050] Refer to Figures 1-3 Figures 1-3 , an embedding groove 221 is opened on one side of the mounting seat 22, and an embedding block 231 is fixedly connected to the side surface of the clamping block 23. The embedding block 231 and the embedding groove 221 cooperate with each other. This cooperation method ensures the stable connection of the clamping block 23 and is convenient for disassembly, assembly and replacement. Through holes 222 are symmetrically penetrated through the top of the mounting seat 22. A cover plate 24 is connected to the top of one of the mounting seats 22. The cover plate 24 plays a protective role to prevent the clamping block 23 and the embedding block 231 from being damaged or falling off by external forces.

[0051] Refer to Figure 4 Figure 4 , the pressing mechanism 3 includes a fixed rod 31 installed on the table top 1. The top of the fixed rod 31 is symmetrically and fixedly connected with first guide posts 311. Sliders 32 are sleeved on the first guide posts 311. An active rod 33 is connected to the inner sides of the two sliders 32. When winding the string, the string to be wound is located between the active rod 33 and the fixed rod 31. The outer sides of the sliders 32 are connected with a second cylinder 34. The second cylinder 34 pushes the sliders 32 to slide on the first guide posts 311, so as to squeeze the double-strand part of the string between the active rod 33 and the fixed rod 31. This design ensures the stability of the string during the winding process and avoids the situation of the string becoming loose or displaced during the winding process.

[0052] Refer to Figure 4 Figure 4 , a first connecting plate 321 is fixedly connected to the inner side of the slider 32, and the active rod 33 is connected to the first connecting plate 321 through bolts. This connection method ensures the stability and reliability of the active rod 33. A second connecting plate 322 is fixedly connected to the outer side of the slider 32. One end of the second connecting plate 322 is connected to the telescopic end of the second cylinder 34. The second cylinder 34 drives the slider 32 to slide on the first guide post 311 by pushing the second connecting plate 322, so as to realize the pressing operation on the string.

[0053] Refer to Figure 2 Figure 2 , a wire insertion hole 111 is penetrated through one end of the winding table 11. The wire insertion hole 111 is used to insert one end of the string to make the position of the string more accurate during the winding process. This design improves the accuracy and efficiency of string winding.

[0054] Refer toFigure 5 , a sliding table 42 is connected to the bottom of the motor 43, and a second guiding column 41 is arranged at the bottom of the sliding table 42, and they are slidably connected; the arrangement of the sliding table 42 makes the motor 43 move more smoothly during the movement process, ensuring the smooth rotation process of the rotating member 45; this design improves the quality and efficiency of the string winding.

[0055] The working principle of the present utility model is as follows:

[0056] When winding the string, first pinch the string by hand and insert one end of the string into the wire insertion hole 111;

[0057] Under the push of the third air cylinder 44, the motor 43 moves towards the position where the string is located, and the rotating member 45 passes through between the fixed rod 31 and the movable rod 33;

[0058] During the movement of the motor 43, through the sliding table 42 arranged at the bottom of the motor 43 and making the sliding table 42 slide on the second guiding column 41, the movement process of the motor 43 can be made more stable;

[0059] Then hang the string on the wire hanging column 46, and then under the drive of the third air cylinder 44, let the motor 43 retreat to the initial position. Immediately afterwards, under the push of the first air cylinder 21, make the two clamping blocks 23 approach each other, squeeze the other end of the string between the clamping blocks 23. At the same time, under the drive of the second air cylinder 34, the slider 32 will be driven to slide downwards on the first guiding column 311, and then squeeze the double-strand part of the string between the movable rod 33 and the fixed rod 31;

[0060] After the string is clamped and fixed, under the drive of the motor 43, the rotating member 45 will be driven to rotate. Since the string is hung on the wire hanging column 46, the winding operation of one end of the string is realized.

[0061] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specifically described and defined, are implemented according to the conventional means in the art.
