Band sawing machine with angle adjustment structure
Technical field
The utility model belongs to saw, particularly a kind of band sawing machine with angle adjustment structure.
Background technology
As shown in Figure 1 and Figure 2, general band sawing machine 10 includes pedestal 11, saw band 12 and buck 13.
Pedestal 11 has reverse upper end 111, bottom 112 and is defined in the breach 113 of 111,112 of upper and lower ends.
Saw band 12 can be in pedestal 111,112 rotations of unrolling in 11 upper and lower ends.
Buck 13 is to be arranged in the breach 113 of pedestal 11, and has the angle adjustment instrument 131 fixed with bottom 112.
By this, workpiece need only be lain on the buck 13, can be with saw band 12 cut workpiece, and adjust the angle of inclination of bucks 13 by angle adjustment instrument 131, change the cutting angle between saw band 13 and workpiece, to meet process requirements.
Only, though said elements can reach the purpose of adjusting cutting angle, so when practical operation, still there is following disappearance and needs to be resolved hurrily:
Because known band sawing machine 10 is to reach the purpose that changes buck 13 and work piece cut angle by the angle of inclination that changes buck 13.But, general buck 13 is to be used for place work piece, being mainly used in provides a machined surface stably, therefore, when buck 13 tilted, workpiece was bound to stablize be placed on the buck 13, and must be dependent on the processor workpiece is bestowed pressure by power, this measure no doubt can be located workpiece, and the danger that travelling workpiece has some setbacks and generation work is dropped is easily but arranged.
Summary of the invention

The specific embodiment
As Fig. 3, Fig. 4, shown in Figure 5, the band sawing machine 20 that the utlity model has the angle adjustment structure comprises pedestal 21, saw band 22, drives structure 23 and angle adjustment structure.
Pedestal 21 has the breach 213 that is defined in 212 of upper end 211 and bottoms.
But drives structure 23 comprises for saw band 22 cover connection and is hubbed at the last drive 231 of pedestal 21 upper and lower ends 211,212, the motor 233 that lower driving wheel 232 reaches forward, reverse driving lower driving wheel 232 and protrudes along axis direction respectively.
Angle adjustment comprises adjusts seat 30, number locating part 40, keeper 50 and buck 60.
Adjusting seat 30 is to be extended in bottom panel 31, the top panel 32 on 37 ends of riser, top by riser 37 and level to constitute.Provide four arc grooves 33,34,35,36 with same axle center 1A, identical radian measure and different radii in riser 37 along axis direction.
Arc groove 33 is to supply the motor 233 of drives structure 23 to pass.
As shown in Figure 5, locating part 40 comprises axle sleeve 41, guide rod 42 and nut 43.
Axle sleeve 41 is to be arranged in respectively in the arc groove 34,36 of adjusting seat 30 risers 37.
Guide rod 42 have pass axle sleeve 41 and with the solid fixed end of pedestal 21 spiral shells 421 and the end of thread 422 that oppositely passes axle sleeve 41 and screw togather with nut 43.By locating part 40 to adjust on the seat 30 pedestal 21 is spacing.
As Fig. 3, Fig. 5, shown in Figure 6, keeper 50 comprises and passes the screw rod 51 adjusting arc groove 35 on seat 30 risers 37 and pedestal 21 and screw togather, sets firmly and the spanner 52 of drive screw 51 and be arranged at spanner 52 and a pad 53 of adjusting 30.
By this,, pedestal 21 can be locked in and adjust on the seat 30, so that pedestal 21 obtains the location with spanner 52 turn screw rods 51.
Buck 60 is that along continuous straight runs is fixed on the top panel 32 of adjusting seat 30, and can pass for saw band 22.
As Fig. 6, shown in Figure 7, when the cutting angle that will change between saw band 22 and workpiece, need only be with spanner 52 pine oil screw rods 51, making the pedestal 21 of band sawing machine 20 is that the centre of gyration rotates relative to adjusting seat 30 with axle center 1A, order is placed through four respectively and has same axle center 1A, the arc groove 33 of identical radian measure and different radii, 34,36, motor 233 in 35, the axle sleeve 41 of two locating parts 40 and the screw rod 51 of keeper 50 are along arc groove 33,34,36,35 move with identical radian measure, receded so that the pedestal 21 of band sawing machine 20 drives saw band 22, change the cutting angle between saw band 22 and workpiece.By this, still steadily fixed placement and can steady suitable displacement on the buck 60 that is the level of state for workpiece.
As Fig. 8, shown in Figure 9, also can in pedestal 21 and adjust to organize between the seat 30 and establish circulator 70.
Circulator 70 comprise self-regulated bed rearrangement 30 along the outstanding locating piece 71 of axis direction, make motion block 72 and be hubbed at the adjustment screw rod 73 of pedestal 21 upper ends 211.
Locating piece 71 has a stopper slot 711 and an axis hole 712 along axis direction that runs through along the radial line direction.
Making motion block 72 is to be placed through rotationally in the axis hole 712 of locating piece 71, provides on it towards locating piece 71 stopper slots 711 screws 721.
Adjust that screw rod 73 has the handwheel 731 that passes pedestal 21 upper ends 211 and by extending and spiral shell is located at thread segment 732 in locating piece 72 screws 721 at handwheel 731 centers downwards.
When the handwheel 731 of screw rod 73 is adjusted in operator's turn and drive thread segment 732 rotations, order is adjusted screw rod 73 and is the state that rotates from body with respect to pedestal 21, at this moment, because thread segment 732 is to be screwed together in the screw 721 of making motion block 72, just drive and make motion block 72 and carry on the thread segment 732 of adjusting screw rod 73, bottom offset, but the axis hole 712 that is subject to locating piece 71 can't be gone up, move down, thereby rotation displacement in axis hole 712, adjustment screw rod 73 is swung in stopper slot 711 radial displacements, and then drive pedestal 21 and recede along the radial line direction, reach the purpose that changes cutting angle.And can make pedestal 21 obtain the location by adjusting screw rod 73 and doing screwing togather and spacing relation of motion block 72, locating piece 71.
Conclude above-mentioned, of the present utility model have following listed advantage and an effect: when the pedestal 21 that makes band sawing machine 20 is the centre of gyration when adjusting seat 30 and rotate with axle center 1A, the screw rod 51 that order is placed through the axle sleeve 41 of four motor 233, two locating parts 40 in the arc groove with same axle center 1A, identical radian measure and different radii 33,34,36,35 and keeper 50 respectively moves with identical radian measure along arc groove 33,34,36,35, receded so that the pedestal 21 of band sawing machine 20 drives saw band 22, change the cutting angle between saw band 22 and workpiece.By this, still steadily fixed placement and can steady suitable displacement on the buck 60 that is the level of state for workpiece, thereby can promote smoothness and security on processing.And more can adjust the angle of inclination of pedestal 21 accurately, and reach effect laborsaving, easy to adjust by the setting of circulator 70.
