Description

A kind of sawing machine send plate travel control device
Technical field
The invention belongs to woodworking machinery field, and be related to a kind of sawing machine send plate travel control device.
Background technology
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.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that a kind of sawing machine send plate Stroke Control Device, present invention solves the technical problem that being the precision that can improve pin displacement.
The purpose of the present invention can be realized by following technical proposal:
A kind of sawing machine send plate travel control device, and sawing machine includes working plate and is fixed on the branch of working plate side Frame, the support are provided with pin, it is characterised in that described to send plate travel control device to include controller, be rotatably connected on branch Two screw mandrels on frame and the Stroke Control motor that two screw mandrels can be driven to rotate simultaneously, the both ends of the pin respectively with two Wire rod thread connects, and the motor shaft both ends of the Stroke Control motor pass the housing of Stroke Control motor, Stroke Control electricity Motor shaft one end of machine is connected with two screw mandrels, and the motor shaft other end of Stroke Control motor is fixed with rotating disk, the rotating disk At least two reflective surfaces are intervally distributed with card in the circumferential, the radian being spaced between adjacent reflective surface is identical, solid on support Surely have an optical sensor with rotating disk face, the controller respectively with optical sensor and Stroke Control motor connection, described anti- The optical sensor is triggered and sends trigger signal and is provided with to controller, controller when smooth surface and the probe face of optical sensor Optical sensor triggering times threshold value, the control is calculated according to displacement threshold value in the displacement threshold value of pin movement, the controller Device processed judges that output control signal control Stroke Control motor is closed when the number of optical sensor triggering is equal to triggering times threshold value.
