Piano bonding hold down gag
The present invention relates to pressing fixing device, particularly relate to piano bonding hold down gag.
In the making production process of piano, owing to piano main body coverage rate is bigger, its outside framework and base great majority are timber and make, thus be unlikely to be and be made up of an independent timber, it is to be surrounded by multilamellar bonding wood materials, but in existing manufacturing process, there is no the bonding compression apparatus that more convenient using effect is good, it mostly is solid shape hold down gag, but the design of each piano shape differs, in use it is subject to certain restrictions, the bonding quality technical difficulty of multiple structure the most own is the most relatively large, bonding quality concerns the performance of the piano completed, service life etc..
Summary of the invention
It is contemplated that for problem present in background technology, and the piano bonding hold down gag provided.
The piano bonding hold down gag of the present invention, it is to be made up of workbench, supporting leg, cylinder and air pump, the supporting leg of its fixed more than three described of workbench periphery, be provided with top board in the surface of workbench, top board holds fixing connection with upwardly extending of supporting leg, the bottom of described top board 5 is provided with Magnet layer, described cylinder head is respectively and fixedly provided with magnet piece, and bottom top board, more than one cylinder in adhesive, and described cylinder is all connected with air pump pipeline.
Preferred as the present invention, described Telescopic-cylinder end is equipped with anti-abrading block.
Preferred, equipped with Pressure gauge on described air pump pipeline as the present invention.
Preferred as the present invention, described workbench is provided with the internally-inlaid of a more than row and rotates roller.
Preferred as the present invention, described workbench is parallel with the opposite face of top board.
The piano bonding hold down gag of the present invention, simple in construction, easy for operation, cost is low, do not affected by piano shape, motility is strong, compresses uniform force stable, effective, work efficiency and finished product bonding quality are provided, the abrasion urging object is little, it is provided that products with adhesive qualification rate, advantageously reduces production cost.

Detailed description of the invention
Below in conjunction with the accompanying drawings 1 and the accompanying drawing 2 piano bonding hold down gag to the present invention, elaborate.
The piano bonding hold down gag of the present invention, it is by workbench 1, supporting leg 2, cylinder 3 and air pump 4 are constituted, the supporting leg 2 of its fixed more than three described of workbench 1 periphery, it is provided with top board 5 in the surface of workbench 1, top board 5 holds fixing connection with upwardly extending of supporting leg 2, certain space is there is between workbench 1 and top board 5, the bottom of described top board 5 is provided with Magnet layer 6, described cylinder 3 top is respectively and fixedly provided with magnet piece 7, in space between workbench 1 and top board 5, Magnet layer 6 and magnet piece 7 all have magnetic attraction power, bottom top board 5, more than one cylinder 3 in adhesive, and can be according to the position at random its place of mobile cylinder 3 of the shape of target compact, described cylinder 3 is all connected with air pump 4 pipeline.Being equipped with anti-abrading block 8 on described cylinder 3 retractable ends, anti-abrading block 8 reduces the abrasion when compressing to object.Equipped with Pressure gauge 9 on described air pump 4 pipeline, the adjustment of pressure can be carried out according to bond condition, to reach more preferable bonding effect.Described workbench 1 is provided with the internally-inlaid of a more than row and rotates roller 10, it is simple to the movement on workbench 1 of the volume bigger object, reduce working strength.Described workbench 1 is parallel with the opposite face of top board 5.
As known by the technical knowledge, the present invention can be realized by the embodiment of other essence without departing from its spirit or essential feature.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only.All changes within the scope of the present invention or within being equal to the scope of the present invention are all included in the invention.
