Embodiment Construction
[0030] The present invention will be described in further detail below.
[0031] Piano back frame tenoning machine, including work piece support table, front and rear pushing mechanism, left and right pressing mechanism, up and down pressing mechanism, frame. The work piece support table, the front and rear jacking mechanism, the left and right pressing mechanism, and the upper and lower pressing mechanism are all installed on the frame, and the front and rear jacking mechanism is located under the work piece support table.
[0032] The front and rear push-in mechanism includes a rear-end positioning plate, three oil cylinders, six pull plates, an oil cylinder seat, and three groups of balanced pull arm mechanisms. The rear end positioning plate is installed at the back of the upper end surface of the workpiece support table, and is used to withstand the rear end of the workpiece. The oil cylinder seat is fixed on the frame and is located under the workpiece support table. The oil...

The invention relates to a piano back pad tenon entering machine. Top purlins and bottom purlins which are placed in the left-and-right direction are contained in die squares and side purlins which are placed in the front-and-back direction, sleepers are tightly attached between the die squares or between the die squares and the side purlins, and tuning peg plates are tightly attached to cover the upper ends of the top purlins, the die squares, the side purlins and the sleepers; the piano back pad tenon entering machine comprises a workpiece supporting table for containing workpieces, a front-and-back ejection-in mechanism for pressing in the workpieces in the front-and-back direction, a left-and-right compression mechanism for compressing the workpieces in the left-and-right direction, an up-and-down compression mechanism for compressing the workpieces in the up-and-down direction and a rack; the position of the left-and-right compression mechanism corresponds the positions of the sleepers, and the position of the up-and-down compression mechanism corresponds the positions of the tuning peg plates. The invention further relates to a piano back pad tenon entering method. The piano back pad tenon entering machine is simple in structure and convenient to operate, working procedures needing large force are completed through machines, the working efficiency is effectively improved, the tenon entering quality is guaranteed, the gluing quality is guaranteed, and the piano back pad tenon entering machine belongs to piano part machining equipment.
Description
Technical field [0001] The invention relates to a processing equipment for piano parts, in particular to a piano back frame tenoning machine and a piano back frame tenoning method. Background technique [0002] The piano back frame is a part of the piano and is located on the back of the piano. The existing installation method is manual installation, which is not only inefficient, but also poor in installation, which affects the quality. [0003] The piano back frame includes the top beam on the upper part, the bottom beam on the lower part, the side beams on both sides, the middle beam, sleepers, pegs, etc. The top and bottom beams are parallel to each other, and the side and middle beams are parallel to each other, standing between the top and bottom beams. The side beam and the middle beam are connected with the top beam and the bottom beam by tenon and tenon. The sleepers are glued between the side beams and the middle beams or between the middle beams by an adhesive, and the...
