Device and method for processing piano shaft bracket

Abstract

The invention discloses a device and a method for processing a piano shaft bracket, wherein the device for processing the piano shaft bracket comprises a conveyer belt, a threading needle soaking device, an oven and a needle withdrawal machine, wherein the threading needle soaking device is arranged beside the conveyer belt and consists of a needle threading machine and a soaking machine; the oven is arranged at the tail end of the conveyer belt; the needle threading machine mainly comprises a feeding device, a work sliding way, a pushing device, a locating device, a drilling device, a shaping needle distributing device, a needle beating device and a control device; the soaking machine mainly comprises a synchronous belt conveying device, a soaking device and a feeding device; and the needle withdrawal machine mainly comprises a feeding device, a blanking device, a locating sliding way, a pushing locating device, a needle pushing device, a needle withdrawal device and a control system. The device for processing the piano shaft bracket can be used for realizing needle threading, soaking, drying and needle withdrawal of the shaft bracket, and has the advantages of being high in degree of automation, high in production efficiency, low in labor cost, etc.

Description

technical field [0001] The present invention relates to the production equipment and method of piano parts, in particular to a kind of processing equipment and processing method of piano axle frame, more specifically, to the processing equipment and processing method of the piano axle frame for threading needles, soaking, drying and pulling out needles . Background technique [0002] Piano pivots are the core components of the piano - the key components that connect the various levers in an action (for example, the pivots in an upright piano action include buttress pivots, damper pivots, linkage pivots, and top There are four kinds of rod and shaft frames), and the key to the smooth movement of the action parts is the quality of the processing of the shaft frame. see figure 1 and figure 2 , the upper end of the piano shaft frame 9 is U-shaped, and the two sides of the U-shaped opening are respectively provided with coaxial shaft frame holes 9-1. center of rotation.

Problems solved by technology

[0003] In the prior art, the above process is generally to arrange a plurality of shaft frames (for example, 20) together, and then use a long shaping needle to pass through the solid bushings in the plurality of shaft frames in sequence, and then place them in the soaking tub Soak for a period of time, and finally put it in an oven to dry, and finally put it on the equipment to pull out the long setting pin. This process is mainly done manually, with low automation and low production efficiency. There are following deficiencies:

[0004] 1. Because the sizing needle is long, it is easy to bend during use, which causes the shaft hole diameter of the bushing to be inconsistent, which affects the manufacturing accuracy; in addition, the sizing needle needs to rotate while advancing during the hole passing process, causing wear after long-term use, which also causes the shaft Inconsistent shaft hole diameter of the lining

[0005] 2. Due to the large number of shaft frames in the primary through hole, the positioning errors of the shaft frames arranged together are prone to errors, which makes the position of the shaft holes of the bushings between different shaft frames misaligned, which will affect the piano after being installed in the same piano. Assembly accuracy
