Description
Technical field
The invention belongs to the woodworking machinery technical field, more particularly relate to the improvement of the saw blade lifting regulation driving mechanism of bench saw.
Background technology
Traditional carpenter is mostly complicated with the lift in height governor motion of the saw blade of bench saw, regulates quite difficulty, and is time-consuming.This just brings inconvenience to the user, is difficult to as required flexibly, regulates the height of saw blade in time, that is be difficult to regulate the degree of depth of work piece saw kerf; And reduced the production efficiency of bench saw; In addition, because its complex structure, the production cost of bench saw self is also high.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of saw blade lifting regulation driving mechanism of bench saw is provided.It can be as required flexibly, the height of lift adjustment saw blade in time, that is regulated the degree of depth of work piece saw kerf, and is simple in structure, regulates, easy to use, and production cost is low, the production efficiency height.
Saw blade (8) and the transmission system thereof that bench saw comprises frame (1), be installed in workbench above the frame (1), be installed in motor (2) on the frame (1), drive with motor (2) and be installed in parts such as electric switch on the frame (1).
In order to achieve the above object, the drive pulley (4) on the axle (3) that the present invention includes the motor (2) that is installed on the frame (1), is fixed on motor (2), be installed in saw blade holder (5) on the frame (1), borrow bearing (6) to be installed in saw blade axis (7) in the saw blade holder (5), be fixed on saw blade (8) on the saw blade axis (7), be fixed on driven pulley (9) on the saw blade axis (7), be installed in the belt parts such as (10) on drive pulley (4) and the driven pulley (9).Motor (2) is installed on the frame (1) by motor mounting plate (11) and connecting plate for electric motor (14).Fixing motor mounting plate (11) on the frame (1), the support of motor (2) is installed on the motor mounting plate (11) with three screws (12).Also fixing axle sleeve (13) on the support of motor (2), axle sleeve (13) is with in the hole that is sleeved on connecting plate for electric motor (14) movingly.Saw blade holder (5) is also with in the hole that is sleeved on a saw blade connecting plate (15) movingly.Have two slotted holes (16) on the connecting plate for electric motor (14), the saw blade connecting plate has two holes on (15), and two screws (17) pass respectively in two holes that two slotted holes (16) are fixed on saw blade connecting plate (15).
After belt (10) is lax, only need loosening with two screws (17), again with connecting plate for electric motor (14) and saw blade connecting plate (15) along relative the drawing back of two slotted holes (16), the axle (3) of the motor (2) that is installed on it and the transmission centre-to-centre spacing of saw blade axis (7) are strengthened, again two screws (17) are tightened at last, just can be made belt tensioning again.That is adjusted its transmission centre-to-centre spacing.With two screws (17) fastened after, connecting plate for electric motor (14) just becomes as a whole with saw blade connecting plate (15).But axle sleeve (13) still can be with respect to connecting plate for electric motor (14) rotating movingly, and saw blade holder (5) also can be with respect to saw blade connecting plate (15) to rotate movingly.
On saw blade holder (5) and the frame (1) the saw blade lifting adjusting structure is installed also.Have 3 slotted holes (18) on the motor mounting plate (11), three screws (12) pass slotted hole (18) and are installed on the support of motor (2).This structure can make motor (2) with respect to motor mounting plate (11) along 3 slotted holes (18) displacement.
The saw blade lifting adjusting structure is by the left socle (19) and the right support (20) that are fixed on the frame (1), be installed in the transverse axis (21) in the hole of left socle (19) and right support (20), be fixed on the handwheel (22) of transverse axis (21) outer end, be fixed on the inner bevel gear (23) of transverse axis (21), bevel gear (24) with bevel gear (23) engagement, be fixed on the screw rod (25) on the bevel gear (24), be installed in the nut (26) on the screw rod (25), fixing the holder (27) of nut (26), be fixed on that holder (27) and saw blade holder (5) are gone up and two ends have the flute profile slide block (3 0) of guide hole up and down respectively and are fixed on frame (1) and go up and pass respectively a group of flute profile slide block (30) guide pillar (28) and (29) of guide hole are formed up and down.
Shake handwheel (22) gently, it just can drive transverse axis (21), bevel gear (23), bevel gear (24), screw rod (25) rotation successively.The screw rod (25) of rotation just can change rotation into moving up and down of nut (26).Nut (26) drives flute profile slide block (30) and moves up and down along guide pillar (28) and (29), and then saw blade holder (5) is moved up and down.That is finished the lifting of saw blade, regulated the height of saw blade.In this course, saw blade holder (5) move up and down make respectively axle sleeve (13) with respect to connecting plate for electric motor (14), saw blade holder (5) with respect to saw blade connecting plate (15) to rotate movingly.Again because connecting plate for electric motor (14) has become as a whole with saw blade connecting plate (15), the transmission centre-to-centre spacing of axle (3) and saw blade axis (7) can not change, and connecting plate for electric motor (14) can only force motor (2) to produce left or right displacement with respect to motor mounting plate (11) along 3 slotted holes (18).
Drive pulley (4) and driven pulley (9) can be multiple ribbed pulley, and belt (10) is many wedges belt.The transmission of multiple ribbed pulley and many wedges belt cooperates accurately, has avoided the slip of belt and moves, and the frequent lift adjustment and the transmission that are particularly useful for saw blade are regulated.
Three screws (12) can be hinged screws.The structure of hinged screw both can make motor (2) with respect to motor mounting plate (11) along 3 slotted holes (18) displacement, can avoid the installation of motor (2) and motor mounting plate (11) too lax again, keep the gap of appropriateness between the two.
Left socle (19), right support (20) can be integral structure with frame (1).This integral structure is processed, assembling is simpler, reliable.
All right mounting guide sleeve (31) in the guide hole up and down of flute profile slide block (30) is to strengthen anti-wear performance, to increase the service life.
Task of the present invention comes to this and finishes.
The present invention can be as required flexibly, the height of lift adjustment saw blade in time, that is regulated the degree of depth of work piece saw kerf, and is simple in structure, regulates, easy to use, and production cost is low, the production efficiency height.It can be widely used in the various bench saws.
