Processing equipment for medium-radius arc surface on piano sound rib

Abstract

The invention discloses processing equipment for a medium-radius arc surface on a piano sound rib. The equipment comprises a supporting pedestal, an external rack, an arc surface processing assembly,an arc-shaped guide assembly and a clamping device, and is characterized in that the arc-shaped guide assembly changes the radius of the outer side of the arc-shaped guide assembly along a motion trail through the relative telescopic action of rod arms of the arc-shaped guide assembly; processing is carried on the arc surface of a to-be-processed piano sound rib fixed to the equipment according toa specific processing technology; the clamping device is transversely fixed on the arc-shaped guide assembly and is used for locally clamping the piano sound rib, so that the piano sound rib is always kept in a stable state in the processing process; and the arc surface processing assembly is installed on the upper end face of the supporting pedestal and located in the middle of the arc-shaped guide assembly, so that when the arc-shaped guide assembly guides the piano sound rib to conduct local track movement, the arc surface processing assembly conducts machining and running-in on the contact surface of the arc-shaped guide assembly and conducts paint rolling and drying on the contact surface.

Description

technical field [0001] The invention relates to the technical field of piano parts processing equipment, in particular to a processing equipment for medium-radius arc surfaces on piano ribs. Background technique [0002] The piano rib is an important part of the piano, which is bonded to the soundboard of the piano to improve the elasticity and hardness of the soundboard, and at the same time it can quickly transmit sound waves to the entire soundboard. The wood texture of the piano soundboard and strings is arranged diagonally from low, middle to high tones, so that the wood texture forms a horizontal and vertical cross network. soundboard. The processing method of the arc surface on the piano ribs in the prior art is to use a woodworking chisel to roughly machine the outline of the arc surface according to the surface of the mold, leaving a certain machining allowance; then use a hook planer to manually press the arc outline Planed out, this processing method has the dis...

Problems solved by technology

The processing method of the arc surface on the piano ribs in the prior art is to use a woodworking chisel to roughly machine the outline of the arc surface according to the surface of the mold, leaving a certain machining allowance; then use a hook planer to manually press the arc outline Planed out, this processing method has the disadvantages of low efficiency, poor precision and high labor intensity, and when using a woodworking chisel for rough machining, if the amount of cutting is large, tearing will occur along the direction of the wood grain, and the tear surface will Even when the surface of the processed contour is exceeded, there are processed products or even waste products; and after the processing is completed, it still needs to be repeatedly run-in. The steps are cumbersome and cannot be mass-produced. Therefore, it is necessary to propose a medium-radius arc surface on the piano rib Processing equipment to solve the above problems
