Abstract
The utility model discloses a kind of bench saw machine knife blade upper-lower height regulating mechanisms, the mechanism includes rack, live spindle passes through rack and connects driving motor, the live spindle side is equipped with blade shaft, the live spindle drives blade shaft by driving member, and the live spindle is arranged the first fixing sleeve, and blade shaft is arranged the second fixing sleeve, first fixing sleeve and the second fixing sleeve are fixedly connected, and first fixing sleeve is equipped with fixing sleeve rotating member.Advantage are as follows: the present apparatus can quickly adjust the blade height of breast bench, realize any height cutting in maximum cutting-height, when not in use, can play the protection to blade with retracting blade with this.
Description
Technical field
The utility model relates to machinery fields, more particularly, to a kind of bench saw machine knife blade upper-lower height regulating mechanism.
Background technique
The blade of the breast bench of the prior art is fixed on the rack more, is not adjustable with the relative altitude of table top, Bu Nenggen
It needs blade can not also be withdrawn to adjust the height of blade when not cutting according to cutting, good maintenance is not had to blade
Effect.
Utility model content
Purpose of utility model: in order to overcome the shortcomings of background technique, the utility model discloses one kind can quick regulating platform
The blade adjustment mechanism of saw blade upper-lower height.
Technical solution: bench saw machine knife blade upper-lower height regulating mechanism described in the utility model, which includes rack, rotation
Turn main shaft and connect driving motor across rack, the live spindle side is equipped with blade shaft, and the live spindle passes through transmission
Member drives blade shaft, the live spindle are arranged the first fixing sleeve, and blade shaft is arranged the second fixing sleeve, and described first is solid
Fixed set is fixedly connected with the second fixing sleeve, and first fixing sleeve is equipped with fixing sleeve rotating member, rotates structure by fixing sleeve
Part can control the first fixing sleeve of rotation, to drive the second fixing sleeve of rotation, turn blade shaft with the live spindle center of circle
It is dynamic, to realize the upper and lower displacement of blade.
Further, the fixing sleeve rotating member includes a fan-shaped axle bed, which is circle with the first fixing sleeve
The heart, and be secured to, it is tooth side structure in the outer circumferential edge of the sector axle bed；The tangent position of the outer circumferential edge of the sector axle bed
Equipped with the worm screw engaged with its tooth side, fan-shaped axle bed arc side can be made to rotate by rotary worm, to realize fixed to first
The rotation of set controls.
Further, the end of the worm screw is equipped with driving handwheel, so that the more convenient rotation of worm screw.
Further, the worm set is equipped with loop bar fixing piece, and the loop bar fixing piece is connected and fixed with rack, so that snail
Bar in the course of rotation do not move by position, and fan-shaped axle bed is only made to generate displacement by own rotation.
Further, the rack is equipped with angle limiting member, and the rotation angular area of fan-shaped axle bed is limited by control
Between realize the restriction to blade upper-lower height.
Further, the driving member is the belt wheel being separately positioned in live spindle and blade shaft, and by more
The transmission of wedge band connection, drives blade with this.
Further, the frame upper end side is the U-shaped arc fluting knot rotated for blade shaft by the center of circle of live spindle
Structure.
The utility model has the advantages that compared with prior art, the advantages of the utility model are as follows: the present apparatus can quickly adjust breast bench
Blade height is realized any height cutting in maximum cutting-height, when not in use, can be played with retracting blade with this
Protection to blade.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further described with reference to the accompanying drawings and examples.
Bench saw machine knife blade upper-lower height regulating mechanism as shown in Figure 1, the mechanism include rack 1, and live spindle 2 passes through rack
1 connection driving motor, 2 side of live spindle are equipped with blade shaft 3, are respectively provided with band on live spindle 2 and blade shaft 3
Wheel, and connected and be driven by V-ribbed belt.
The live spindle 2 is arranged the first fixing sleeve 4, and blade shaft 3 is arranged the second fixing sleeve 5, the first fixing sleeve 4 and
The setting of two fixing sleeves 5 does not influence the rotation of live spindle 2 and blade shaft 3 itself, and first fixing sleeve 4 and second is fixed
Set 5 is fixedly connected, and the first fixing sleeve 4 is connected and fixed a fan-shaped axle bed 6, which can be rotated with the first fixing sleeve 4
Main shaft 2 is center of circle rotation, is tooth side structure in the outer circumferential edge of the sector axle bed 6, and the tangent position of its outer circumferential edge extends
Direction is equipped with the worm screw 7 engaged with its tooth side, and worm screw 7 is connected and fixed by loop bar fixing piece 8 with rack 1, rotates in worm screw 7
When, it will not be subjected to displacement with rack 1, the outer end of worm screw 7 is equipped with driving handwheel 10, and rotate driving handwheel 10 realizes worm screw
7 rotation makes fan-shaped axle bed 6 with live spindle 2 for center of circle rotation, to drive blade shaft 3 by tooth side engagement rotation
It is center of circle rotation, the i.e. upper and lower displacement of blade with live spindle 2.
It is equipped with angle limiting member 9 in 1 side of rack, the limited post being specially fixed on the rack is in fan-shaped axle bed 6
Hollow structure offers the track mobile for limited post, by controlling the length of track, to control the rotation of fan-shaped axle bed 6
Angular interval, i.e. the upper-lower height section of blade.
In the rack 1 end edge be for blade shaft 3 with live spindle 2 be the center of circle rotation U-shaped arc fluting structure.
