Description
Technical field
The utility model relates to a kind of perforating device of accordion thread rolling shaft, is the special process equipment of a kind of musical instrument.
Background technology
The thread rolling shaft of traditional accordion is in when punching, need to be by manually thread rolling shaft being dragged, thus punch by puncher.When manually dragging, need to determining the required distance that drags of thread rolling shaft with the fixed block of graticule, just can carry out determining of position, hole.Can cause the thread rolling shaft punch position to have certain error yet only make reference with graticule, the thread rolling shaft that final production goes out is of low quality, and the careful work degree is high when manually dragging thread rolling shaft, operation inconvenience.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of perforating device of accordion thread rolling shaft is provided, and its punch position is accurate, and is easy to operate, has guaranteed the thread rolling shaft quality.
The purpose of this utility model is achieved in that
The perforating device of the utility model accordion thread rolling shaft, comprise slide plate, the two ends, the left and right sides of slide plate are fixed with two fixed blocks, have a thread rolling shaft locating hole on the fixed block, the top perforate of one of them thread rolling shaft locating hole also is provided with bolt, be fixed with the punching seat between former and later two fixed blocks, have the thread rolling shaft through hole on the punching seat, the top of punching seat has pin hole, be provided with puncher directly over the punching seat, front side and the locating piece at slide plate top fix, and the front side of locating piece has some locating slots, the front side of locating piece is fixed with stopping means, and the limited block on the stopping means matches with locating slot.
Described thread rolling shaft through hole with about on two fixed blocks the thread rolling shaft locating hole in a straight line.
The perforating device of the utility model accordion thread rolling shaft has the following advantages:
When the perforating device of the utility model accordion thread rolling shaft need to move thread rolling shaft, only need dragging skateboard, when locating piece slides with slide plate, the limited block of stopping means just can snap in the next locating slot of locating piece, just thread rolling shaft can be moved into place again, if the position of so just reserving locating slot on the locating piece, just can accurately punch to thread rolling shaft, not only easy to operate, and guaranteed the quality of thread rolling shaft.
