Three, determine crown cut height
(1) above first electricity consumption plane planing crown cut, reserve the line of having drawn, then dig to line position that model is portrayed the line of can not planing with hand plane; (2) in backrest, bore the screw hole of iron plate and the fastening use of backrest; (3) drill string screw hole: hole on soundboard now, then with 1# emery cloth, polished in hole, drill bushing is put into hole, hole along drill bushing; (4) by dorsal column horse that side is remembered nail positional number, on crown cut, measure by Steel Ruler, be drawn on crown cut.
Four, rush horse nail hole, bore horse nail hole
(1) with the model of respective model, after capturing position is fixing, rush horse nail hole by model.Note the angle of inclination in hole depth and hole, 3 identical directions need consistent; (2), in the appropriate location boring at crown cut stepping place, crown cut stepping place is fixed with screw.
Five, plant Ma Ding
Horse is followed closely to circle and enter horse nail hole, horse nail ride out requires consistent, and angle of inclination meets the requirements.
Six, milling horse flower
(1) crown cut face is smooth with 1# sand papering, be coated with molybdenum disulfide, the light of dishing out after doing; (2) with milling Ma Huaji milling horse flower, upper facing cut is to three centerline holes, and the degree of depth of lower facing cut is generally: high pitch 2mm, and middle pitch 4mm, 95 ° of angles, are arc by mill off part.Again by bass crown cut chamfered edge.
Therefore traditional crown cut process steps is loaded down with trivial details, working (machining) efficiency is low, and low precision is not suitable for large-scale production.
Utility model content
In order to solve the above-mentioned technical matters existing in prior art, the utility model provides a kind of piano crown cut processing unit (plant), comprise frame and base, the X-axis servomotor that described base is provided with fixed station and fixed station is moved, the Y-axis servomotor that described frame is provided with mobile platform and mobile platform is moved along rack rail, the first surface of described mobile platform is provided with on one side surveys high sensor and the high mechanism that mates horses, another side is provided with Chan Mahua mechanism and bores horse nail holes mechanism, and on described mobile platform, contrary with first surface second is provided with and plants horse nailing machine structure.
