Embodiment 2
As shown in Fig. 1, Fig. 3, Fig. 5, the present embodiment provides a kind of plate shearing machines of band shearing positioning function, in embodiment 1
On the basis of be further improved, increase shearing 600 structure of positioning component, can relatively accurately judge plate cutting position,
To guarantee the accuracy of shearing board material length.The structural principle of shearing positioning component 600 is carried out with reference to the accompanying drawing detailed
Explanation.
In conjunction with shown in Fig. 5, Fig. 6 and Fig. 7, shearing positioning component 600 is mounted on the left and right sidesing wall plate above plate shearing machine bottom knife
It mainly include a position line 610, a pair of of strainer 620 and a pair of of positioning seat 630 on 100.
Wherein, a pair of of positioning seat 630 is separately mounted on the front end face of two wallboards 100 in left and right, portable for installation
Property and consider the tension method of subsequent position line 610, positioning seat 630 divides for 632 two parts of fixed part 631 and adjustment portion, the two
Perpendicular between plate face, fixed part 631 is used to positioning seat 630 being fixed to two wallboards 100, and adjustment portion 632 is for installing
Strainer 620 opens up two fixation holes 633 on fixed part 631 along the vertical direction, a tune is transversely opened up in adjustment portion 632
Knothole 634, and herein, fixation hole 633 and adjustment hole 634 are all made of waist-shaped hole.Positioning seat 630 passes through fixed part by bolt
Fixation hole 633 on 631 is installed on wallboard 100, vertical when being installed by adjustable a pair of of the positioning seat 630 of fixation hole 633
The height in direction guarantees that subsequent position line 610 is in horizontality；And adjustment hole 634 is adjusting 620 front and back of a pair of of strainer
To position, be adjusted position line 610 tense after position location.
For strainer 620 for position line 610 to be installed and tensioned, it is stub shape, has perforative centre bore 623, and its
It is divided into thread segment 621 and locking end 622 along its length.Wherein, thread segment 621 passes through the adjustment hole 634 in adjustment portion 632
Afterwards, two sides pass through locking nut 640 and fasten；The screw hole of connection centre bore 623 is opened up in locking end 622, can be revolved in screw hole
Enter lock-screw 624.And after the both ends of position line 610 are each passed through the centre bore 623 of a strainer 620, pass through locking screw
Nail 624 compresses, to tense a position line 610 along bottom knife edge of a knife direction between a pair of of strainer 620.Herein, it positions
Line 610 uses wire, and intensity is high, and for diameter in 1~2mm, the projection thickness on plate is more appropriate, both guarantees to see
Clearly, alignment precision is also relatively high.
In addition, light source is set in the top of position line 610 to increase the clarity that position line 610 projects on plate, this
Light source can be incandescent lamp, LED lamp tube etc..Before use, by adjusting strainer 620, so that throwing of the position line 610 under light source
Shadow is just overlapped with the bottom knife edge of a knife, position when both can determine shearing by projection.
In shearing manipulation, plate is protruded between bottom knife, and light source irradiates position line 610, and position line 610 projects to plate
Expect that surface forms one of projection line, the projection line and plate cutting position alignment can be driven cutter and carry out shearing manipulation.This
Mode is simple and practical, can drop alignment function difficulty, greatly improves shear efficiency, improves shear precision.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
