The clamping and cutting device comprises a bench saw and a base, a saw blade hole is formed in the base, a sliding groove is formed in the portion, on one side of the saw blade hole, of the base, a sliding block is arranged in the sliding groove in a matched mode, a movable platform is arranged at the top of the sliding block, at least two pairs of clamping blocks are fixed to the top of the movable platform, a clamping groove is formed between each pair of clamping blocks, a protractor is fixedto the side portion of the movable platform, a fixing plate is fixed to the protractor, clamping devices are arranged on the other sides, opposite to the saw blade hole, of the two clamping grooves respectively, a rotating shaft hole is formed in the circle center of the protractor, a rotating shaft is fixed to the sliding block, an arc-shaped groove is formed in the protractor, a screw hole is formed in the sliding block, an adjusting bolt is arranged in the screw hole in a matched mode, and the base is provided with a lower supporting block, an upper supporting block and a baffle on the other side of the saw blade hole. The clamping and cutting device is simple in structure, convenient to use, low in manufacturing cost and capable of achieving rapid cutting of the piano hammer rods andgreatly improving efficiency.

Description

technical field [0001] The invention relates to a clamping and cutting device for multi-length piano hammer rods. Background technique [0002] The main components of the piano are the mark, the middle plate, the tripod and the piano shell. The mark is the string tension system assembly of the piano, which belongs to the sound source part of the piano. The middle plate is used to place the keyboard, which belongs to the playing part of the piano. The frame is used to support and move the piano, and the piano case is used to decorate the appearance of the piano. [0003] The piano hammer is the part of the piano that is struck when the key is pressed. Its length is fixed, and the length of the hammer of each different model of piano may be different, and the angle of the rear end may also be different. When the hammer is produced, it is first produced uniformly. Get a hammer stick of a certain length, and then cut the hammer stick to the required length according to the need...

Problems solved by technology

[0003] The piano hammer is the part of the piano that is struck when the key is pressed. Its length is fixed, and the length of the hammer of each different model of piano may be different, and the angle of the rear end may also be different. When the hammer is produced, it is first produced uniformly. Get a hammer stick of a certain length, and then cut the hammer stick to the required length according to the needs of the piano during assembly. At present, there is still a lack of special cutting tools, and the cutting can only be done after manual measurement. The efficiency is low and cannot meet the production requirements. Require
