Description

Technical Field

[0001] This utility model relates to the field of musical instrument processing equipment technology, and in particular to a bamboo processing fixture for musical instrument bows. Background Technology

[0002] At the 19th Conference of the Parties (CoP19) in November 2022, Brazilian rosewood was listed under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) for protection, which led to a significant reduction in the production of violin bows made from this material. In view of this, it has become inevitable to use other materials to replace Brazilian rosewood in the production of violin bows.

[0003] Studies show that bamboo fibers have an extremely consistent orientation, superior to most high-grade woods; the microfibril angle of bamboo is between 7-13°, while the microfibril angle of most woods is around 25° and varies considerably, thus bamboo's Young's modulus along the grain is much better than that of wood; bamboo has a lower density, approximately 0.7-0.9 g / cm³; bamboo has a straight grain, good elasticity, and is not easily deformed after proper bending and shaping; choosing the right bending direction can make the bent shape last longer. Therefore, a bow made of bamboo is not only strong but also of suitable weight. In addition, the solid bamboo bow stick is of uniform material, and the center of gravity of the bow is clear, making it more suitable for violinists to operate and play music. Therefore, people have proposed a technical solution for making bows using bamboo.

[0004] However, due to the thickness and material properties of bamboo, the bow stick usually needs to be made of spliced ​​bamboo pieces. The dimensional accuracy of the bow stick directly affects the various performance characteristics of the bow; therefore, obtaining bamboo of sufficient precision is a key factor in producing high-quality bamboo bows. In the production and processing of bamboo for bows, it has been found that existing processing fixtures, due to differences in their intended use and standards, suffer from low processing precision and low efficiency when used to process bamboo, seriously hindering the large-scale production of bamboo bows. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing processing fixtures, such as low processing accuracy and low processing efficiency, and to propose a bamboo processing fixture for violin bows.

[0006] This utility model provides a bamboo processing fixture for violin bows, including a left clamping block, a right clamping block, and several fasteners; a left inclined surface is provided on one side of the left clamping block, and a right inclined surface is provided on one side of the right clamping block, the left inclined surface and the right inclined surface cooperate to form a working groove; corresponding clamp fixing grooves are provided on the side of the left clamping block away from the left inclined surface and on the side of the right clamping block away from the right inclined surface; several corresponding mounting holes are provided through the left clamping block and the right clamping block in the horizontal direction; the fasteners are adapted to be installed in the mounting holes for connecting the left clamping block and the right clamping block.

[0007] This utility model discloses a bamboo processing fixture for violin bows. Based on the characteristics of bamboo used for violin bows, a working groove for bamboo processing is formed on the inclined surface of the clamping block. The shape and size of this working groove are adapted to the bamboo product. Placing the bamboo to be processed in the working groove allows for direct processing to obtain bamboo products that meet the shape and size requirements, resulting in higher processing efficiency and precision. Simultaneously, the fixture fixing groove on the clamping block enables quick installation, fixing, and disassembly of the tooling, making it suitable for various processing environments. This bamboo processing fixture for violin bows has a simple structure, is easy to install and disassemble, and offers high processing efficiency and precision, making it suitable for large-scale production and processing of bamboo for violin bows.

[0008] Preferably, the processing fixture further includes at least one intermediate clamping block, which is disposed between the left clamping block and the right clamping block; the intermediate clamping block is provided with two opposing intermediate inclined surfaces, which can cooperate with the inclined surfaces of adjacent clamping blocks to form working grooves; by setting the intermediate clamping block, the number of working grooves can be increased, so that multiple bamboo materials can be processed at the same time, and multiple sizes can be processed on the same fixture, resulting in higher processing efficiency.

[0009] Preferably, the intermediate clamping block is provided with mounting holes that are compatible with the left and right clamping blocks.

[0010] Preferably, the fastener is a screw.

[0011] Preferably, the fasteners are staggered in the two adjacent mounting holes; staggered installation can better fix the clamping blocks and adjust the distance between the clamping blocks from different directions, thereby improving the dimensional accuracy of the fixture.

[0012] Preferably, the number of fixture fixing slots is not less than two, and at least one fixture fixing slot is provided at either end of the left clamping block and / or the right clamping block; by setting the fixture fixing slots at the ends of the clamping blocks, the machining fixture can be better fixed.

[0013] Preferably, the shape and size of the working groove are adapted to the bamboo material used for the bow.

[0014] Preferably, the length of the working groove is not less than the length of the bamboo product for the bow; this facilitates the rapid processing of the bamboo product for the bow.

[0015] Preferably, the processing fixture is also provided with a measuring scale for measuring the length of the bamboo product; by setting the measuring scale, the length of the bamboo can be directly obtained through the fixture, which is beneficial to improving processing efficiency and dimensional accuracy; more preferably, the measuring scale is set on the upper surface of the left clamping block and / or the right clamping block away from the inclined plane.
