A kind of sawing machine send plate travel control device
The invention belongs to woodworking machinery field, and be related to a kind of sawing machine send plate travel control device.
Wood sawing machine is small-sized sawing machine, and sawing machine common at present is the defined location that saw disc is fixed on sawing machine
On, then by promoting plank movement to realize cutting to saw disc, due to occurring that position is offset when promoting plank movement, therefore this kind
The precision of sawing machine cutting is not high.
In order to improve the precision of cutting, people devise the sawing machine with removable saw head, such as Chinese patent literature public affairs
A kind of wood sawing machine opened【Publication No. CN103358360A】, by the way that timber for sawing is placed on the table, then running saw
Head realizes cutting, because the moving displacement for sawing head is fixed, therefore can accurately cut timber.It is general on the sawing machine of the type
All there is backer, that is, can determine that the pin of the location of workpiece to be cut, when workpiece and pin against after be that workpiece moves into place, due to
The cut lengths of workpiece can be adjusted often, also just need the frequent shift position of pin, cutting accuracy and the pin movement position of workpiece
The precision put has direct relation, and pin, which relies primarily on, at present is engraved in the scale on sawing machine to determine its particular location, in operation
Worker is needed to be confirmed, the typically minimum precision of scale is 1mm, and the precision for also limiting backer is up to 1mm, plus scale
Inherently there is certain error, and also there is certain error when aliging scale so that the minimum precision of pin displacement can be more than
1mm, so as to cause workpiece its minimum precision in positioning to be more than 1mm, its precision is relatively low, causes the workpiece size cut down
It is inaccurate.
