Description

Tool for cutting length of piano assembling mallet handle

Technical Field

The utility model relates to a piano production facility technical field especially relates to an instrument of piano assembly mallet handle length cutting.

Background

At present, when the piano is assembled and the length of a mallet handle is finely adjusted, a file or an art designer knife is adopted for cutting, the mallet handle cannot be fixed, certain dangerousness and dust generation exist in the process of file and cutting, the accuracy is poor, the efficiency is low, and the requirement on the experience and technical level of an assembly technician is high.

Disclosure of Invention

For overcoming the deficiencies in the prior art, the utility model aims to provide a piano assembly mallet handle length cutting tool with simple structure, convenient operation and accuracy meeting the requirements.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a tool that piano assembly mallet handle length was cut, includes the cutting nipper, and the cutting nipper has two pincers bodies that rotate to link together, and two pincers bodies constitute by the binding clip and the rear end handle of front end, have the location round hole that is used for fixed mallet handle on the binding clip of one of them pincers body, and the side of another pincers body has the cutting blade.

Further, the diameter of the positioning round hole is 6mm.

Furthermore, a buffer spring is connected between the handles of the two forceps bodies.

Furthermore, the outer walls of the handles of the two forceps bodies are respectively provided with anti-skid lines.

The utility model adopts the above structure, during the use, insert the hammer head handle in the round hole, the thickness adjustment of cutting as required inserts the position of location round hole, grabs behind the position adjustment and presses the handle and can easily cut. Because the cutting blade of this instrument is sharp, can carry out essence, little cutting, the minimum 0.3mm that can realize of cutting thickness completely accords with and surpasss the required precision of piano hammer assembly. In addition, the tool has low requirement on the technical level of a piano assembling technician but the precision completely meets the requirement, and the tool can be used for a factory piano assembling production line and can also be used for daily maintenance of a piano maintenance technician. In a word, the utility model discloses simple structure, the adjustment is convenient, and the accuracy is high, has improved the assembly efficiency of piano greatly.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments;

FIG. 1 is a schematic view of the present invention;

fig. 2 is a cutting process diagram of the present invention.

Detailed Description

As shown in fig. 1, the utility model relates to a tool for piano assembly mallet handle length cutting, it includes the cutting nipper, and the cutting nipper has two pincers bodies 1 that rotate to link together, and two pincers bodies 1 comprise binding clip 11 and rear end handle 12 of front end, have the location round hole 13 that is used for fixed string mallet handle on the binding clip 11 of one of them pincers body 1, and the side of another pincers body 1 has cutting blade 14.

As one example, the diameter of the positioning circular hole 13 is 6mm.

Preferably, the buffer spring 2 is connected between the handles 12 of the two forceps bodies 1, and the buffer spring 2 can reduce the impact force during the shearing process and improve the shearing quality.

Preferably, the outer walls of the handles 12 of the two forceps bodies 1 are respectively provided with anti-slip grains 15, so that the reliability of holding can be improved.

As shown in FIG. 2, in the piano production line, the leveling and height adjustment of the hammer is required for the accuracy of the striking point when assembling the hammer, and it is important to precisely adjust the length of the hammer shank 3. The illustration shows that the hammer shank 3 is inserted into the positioning round hole 13 of the tool, the position of the insertion is adjusted according to the length to be cut, the positioning round hole 13 of the tool can effectively and stably fix the hammer shank 3, and the hammer shank can be easily cut by grasping the handle 12 after the position adjustment. Because the cutting blade 14 of this instrument is sharp, can realize can carrying on the essence, little cutting thickness is 0.3mm at least, accords with and surpasss the required precision of piano hammer assembly completely. In addition, the tool has low technical level requirement on a piano assembling technician but the precision completely meets the requirement, and can also be used for daily maintenance of a piano maintenance technician.

The practice of the present invention has been described with reference to the accompanying drawings, but the invention is not limited to the embodiments described above, which are illustrative rather than limiting, and it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
