Specific embodiment
As shown in Figure 2,3, a kind of precise machining device of steel plate of the present invention includes for driving steel plate 10 to transport back and forth
Dynamic conveying mechanism 40, and the workpiece polishing mechanism of 40 top of conveying mechanism is set；The workpiece polishing mechanism includes by driver
Structure drives the sand belt 33 of rotation, and the sand belt 33 extends laterally to 40 two sides of conveying mechanism.The workpiece polishing mechanism edge
10 direction of motion of steel plate is arranged one group or more, and by transmission mechanism control contact or far from steel plate 10, and each group of workpiece polishing mechanism is equal
It can independently rotate clockwise or counterclockwise.It can according to need the rotation of independent choice either direction, such as one group rotation direction
It is identical as the direction of motion of steel plate 10 in contact surface, and secondly organizing rotation direction in the direction of motion phase of contact surface and steel plate 10
Instead, increase the diversity of technique.33 roughness of sand belt of the workpiece polishing mechanism of difference group is not identical.Such as it is arranged three groups, first
The roughness of group be it is thick, second group be in, third group be thin etc..Multiple groups carry out polishing simultaneously can be improved efficiency and imitates polishing
Fruit is more uniform.It is equipped with dedusting mechanism 34 close to sand belt 33 and 10 contact position of steel plate, the dedusting mechanism 34 is laterally extended
To 40 two sides of conveying mechanism.The dedusting mechanism 34 can be water spraying mechanism or dust collection mechanism or the two combination.
The present invention at least provides the embodiment of two kinds of workpiece polishing mechanisms: one, the workpiece polishing mechanism include a driving wheel

Mechanism 40 is arranged, for driving sand belt 33 to contact or far from steel plate 10.Secondly, the workpiece polishing mechanism include one being coated with throwing
The roller of light belt 33, the roller are contacted by transmission mechanism control or far from steel plates 10.Under same idea of the invention, as long as sharp
Increase polishing span with the sand belt 33 of soft quality, while polishing the traverse of steel plate 10, it should be understood that the present invention
Simple deformation.
The present invention also discloses a kind of method for fine finishing of steel plate, steel plate 10 are delivered to below workpiece polishing mechanism, by cross
The sand belt 33 for being greater than steel plate 10 to width continuously polishes to 10 surface of steel plate, continues steel plate 10 to pros while polishing
To movement；It drives steel plate 10 to move to opposite direction after completing primary polishing, and is continuously polished while movement；Drive steel
10 back and forth movement of plate and simultaneously continuous polishing, until the finish of steel plate 10 reaches threshold value.One group or more of polishing is set
33 roughness of sand belt of mechanism, every group of workpiece polishing mechanism is different, polishes simultaneously according to the selection of the threshold value of finish is one or more groups of.
The workpiece polishing mechanism direction of rotation of two groups of operated adjacents is opposite or identical.
The precise machining device and its method for fine finishing through the invention work in one group of workpiece polishing mechanism and revolving speed exist
In the state of 100r/min, polishing once can be to the finish of 80 mesh.It is worked at the same time in two groups of workpiece polishing mechanisms and revolving speed exists
In the state of 500r/min, polishing one to the finish that can achieve 120-180 mesh twice.It is worked at the same time in three groups of workpiece polishing mechanisms
And revolving speed, under 50r/min state, polishing once can achieve the finish of 240 mesh back and forth.In three groups of workpiece polishing mechanisms while work
Make and revolving speed is under 10r/min state, back and forth polishing two to the finish that can achieve 320-600 mesh three times.600 purposes are bright and clean
Degree can direct productive target product, be not necessarily to subsequent further polishing completely after steel plate cuts parting, reach non-
Normal good technical effect.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas
The corresponding change of kind and deformation, and all these changes and deformation all should belong to the protection model of the claims in the present invention
Within enclosing.
