Telescopic cross type adhesive fixation device for guitar board bonding

Abstract

The invention discloses a telescopic cross type adhesive fixation device for guitar board bonding. The telescopic cross type adhesive fixation device comprises a telescopic cross bracket and fixationclamps. The telescopic cross bracket includes an upper joist and a lower joist that are intersected; and the upper joist and the lower joist are bidirectional telescopic rods and are connected by a rotating shaft. The fixation clamps arranged at the two ends of the upper joist and the two ends of the lower joist respectively include bolt clamping devices and slot bases fixedly connected with the two ends of the upper joist and the two ends of the lower joist. The bolt clamping devices include support gaskets arranged in the slot bases; pressing gaskets are arranged above the support gaskets; and the support gaskets and the pressing gaskets are connected with slot bases by knob bolts. The telescopic cross type adhesive fixation device having a stable structure is used conveniently; two layers of sticky materials can be clamped during the guitar board bonding process conveniently; the clamping effect is good; the position is fixed accurately; sliding or deviation of pasting of the two layers of sticky materials is avoided; and the pasting position accuracy is improved.

Description

technical field [0001] The invention relates to a guitar processing device, in particular to a telescopic cross-shaped adhesive fixing device for guitar sticking boards. Background technique [0002] Guitar (Italian: Chitarra), also translated as guitar or violin. A plucked plucked instrument, usually with six strings, similar in shape to a violin. The guitar is often regarded as the main instrument in pop music, rock music, blues, folk songs, and flamenco. In the field of classical music, the guitar is often performed as a solo or duet; of course, in chamber music and orchestral music, the guitar also plays a considerable role as a foil. Classical guitar, violin and piano are listed as the world's three most famous musical instruments. [0003] Gluing is an indispensable step in the process of making guitars, such as: gluing the side and back panels of guitars, gluing guitar sound beams, gluing guitar panel guards, etc. The two layers of materials are tightly attached, ...

Problems solved by technology

[0003] In the process of guitar making, the step of gluing is indispensable, such as: gluing the side and back of the guitar, gluing the guitar sound beam, gluing the guitar panel guard, etc., all need to be glued, and after gluing, in order to ensure the sticking The two layers of materials are tightly attached, and it is usually necessary to apply pressure during the glue solidification process to compress the two layers of materials. However, due to the curved curvature of some of the material edges during the guitar gluing process, it is difficult to use conventional fixtures. Clamping, the current common method is to use dovetail clamps to clamp the edge of the glued two-layer material, or place a heavy object on the top of the glued two-layer material to compress the glued two-layer material; The problem that the two sides of the sticky two-layer material bears a lot of force, and the middle part is less stressed, easily leads to the problem of unstable paste in the middle part. The force range is large, and the adhesive paste is relatively stable, but the adhesive two-layer material is prone to slipping or shifting when heavy objects are pressed, resulting in skewing and inaccurate material pasting positions.

[0004] Therefore, at present, in the guitar gluing step, there are problems that the pasting material is difficult to be accurately fixed, the glue quality is unstable, and the pasting position is not accurate.
