Piano hammer head grinding machine

Abstract

The invention provides a piano hammer head grinding machine. A grinding motor is connected with a sand tray by an adjusting bolt; the grinding motor and an air inlet of a dust sucking pipe are arranged on a support frame; a transmission lead screw and a moving rail are arranged at the same side surface of a worktable; the lower end of the support frame is connected with the transmission lead screw and the moving rail at the same time; a dust storing box is arranged at the tail end of an air outlet of the dust sucking pipe; a motor is connected with a control box connected with a dust storing box, a cylinder and the transmission lead screw; the horizontal position of the support frame is arranged on the worktable; a fixing frame is arranged above the worktable and is provided with the cylinder; the cylinder is connected with a clamp; the transmission lead screw, the moving rail and the clamp are parallel with one another. The continuous grinding on a piano strip is realized by the grinding motor, the transmission lead screw and the moving rail; the dust sucking pipe is adopted to timely clear generated dust; the piano strip is not influenced by the falling dust adhered to the surface of the piano strip in the grinding process, and the machining efficiency of the sand tray is ensured.

Description

technical field [0001] The invention relates to the technical field of processing piano hammers, in particular to a piano hammer grinding machine. Background technique [0002] The quality of the mallet for the piano hammers plays a vital role in the sound of a piano. In order to ensure the continuity of the piano scale, after the adjacent mallets are arranged in the order of the scale, the height of the mallet from the treble to the bass forms a continuous slope with a smooth transition. That is to say, in the processing process of mallet woolen, it is necessary to obliquely cut the woolen raw material. Glue pressing and trimming to get the required mallet. [0003] During the bevel cutting and slitting process in the early stage, the cross-sectional shape of hammer wool is generally trapezoidal, and often has fine knife marks. In order to process it into a hammer with a pear-shaped cross section, it is necessary to further polish the cut cloth. At present, this kind of...

AI Technical Summary

Problems solved by technology

At present, this kind of grinding process is basically completed by manually operating the grinding disc. Not only is the repetitive labor strong, it is easy to produce errors in production, and a large amount of woolen dust is generated during the grinding process, which is not conducive to the occupational health of production workers.
