Description

Guitar side plate fixing and standing device

Technical Field

The invention belongs to the field of guitar processing, and particularly relates to a guitar side plate fixing device.

Background

A guitar is a plucked instrument, typically six strings, similar in shape to a violin. Guitars are typically equipped with strings, and with a string-adjusting structure, on a wooden whole, which generally comprises a head, a neck, and a resonance box. The resonance box is mainly used for carrying out resonance amplification on vibration and sound of strings, and the resonance box is the part occupying the largest volume in the guitar. In the production process, the side plates of the resonance box are required to be bent into the shape of the eight characters, and then the bent side plates are placed still to enable the side plates to be completely shaped, so that the side plates are glued with the upper plate surface and the lower plate surface of the resonance box, and the resonance box is completely shaped. But traditional processing mode is that the curb plate with the resonance box is adorned in the inside through the mould, then stew the curb plate and wait that its complete design is demolishd the mould and take out the curb plate of design, and the process is comparatively loaded down with trivial details, and production efficiency is lower.

Disclosure of Invention

The invention aims to provide a guitar side plate fixing and standing device which can be used for conveniently disassembling side plates and integrally placing the side plates.

In order to achieve the aim, the basic scheme of the invention provides a guitar side plate fixing and standing device, which comprises a base and a positioning device, wherein the positioning device comprises a rotating shaft, a supporting cylinder and two relatively sliding abutting pieces, a shaping module is arranged on the base and comprises monomer modules distributed in four directions of front, back, left and right, and the outer edge of the monomer module is matched with the shape of a guitar side plate; the supporting piece is provided with a rack-shaped transmission part and a sliding part, a gear matched with the transmission part and a conical expansion part are arranged on the rotating shaft, a tightening sleeve matched with the expansion part and a guide ring matched with the sliding part are arranged on the supporting cylinder, a tightening nut for tightening the tightening part is connected with the supporting cylinder in a threaded manner, and the rotating shaft can be fixed by rotating the tightening nut; the device also comprises a coil spring, the central end of the coil spring is connected with the rotating shaft, and the outer end of the coil spring is connected with the supporting cylinder; the sliding part is in a rod shape.

The principle of the basic scheme is as follows: and the molded side plates are placed on the shaping module, when the shaping module is installed, the transmission parts of the two resisting parts are matched with the gear, then the rotating shaft is rotated, the gear rotates along with the rotating shaft, and the gear enables the two resisting parts to slide relatively. When the two resisting parts slide relatively, the guitar side plates are abutted against the shaping module, because the two sides are abutted against simultaneously and the two abutting parts are driven by the same gear, namely, the two guitar side plates are stressed the same. The tightening nut is rotated to enable the tightening sleeve to tighten and hug the expansion part, and the abutting piece abuts against the guide ring at the moment so as to fix the rotating shaft. When the tightening nut is required to be loosened, the tightening piece can be loosened by only loosening the tightening nut and then reversing the rotating shaft.

The beneficial effect of this basic scheme lies in: the guitar side plate fixing and standing device is mainly used for standing and shaping the molded guitar resonance box side plate and can be used together with a baking device. The two support members apply the same force to the guitar side plates, and the guitar side plates are kept in a stressed state by the cooperation of the tightening nuts, the expansion parts and the tightening sleeves, so that the side plates can keep the molding state of the side plates for a long time in the drying process and cannot deform. The device simple structure, easy operation, assembly and disassembly are efficient. Meanwhile, the device has small volume, light weight and small use space, is convenient for arrangement and placement and is suitable for large-scale production. The arrangement of the coil spring enables the abutting piece to be quickly loosened when the tightening nut is loosened. The rod-shaped sliding part is easy to process.

An optimization scheme I: the rotating shaft is provided with a rotating handle. The arrangement of the rotating handle facilitates the driving rotation shaft of an operator.

And the optimization scheme II is as follows: the abutting piece is provided with an abutting portion, and the abutting portion is arc-shaped. The arc-shaped abutting part can adapt to the arc shape formed by the guitar side plates.

And an optimization scheme III: the abutting piece is provided with an abutting part, and the abutting part is a roller. The arc-shaped abutting part can adapt to the arc shape formed by the guitar side plates.
