Abstract

The utility model relates to a woodworking band saw which belongs to a woodworking machine and is composed of a base, a machine frame, an upper machine box, a lower machine box, a working table, an electric machine, an upper band wheel, a lower band wheel, a tensioning mechanism of a band saw blade, the band saw blade, a guide component of the band saw blade, etc., wherein the guide component of the band saw blade is composed of a guide rod, an upper guide block, a lower guide block, a rack bar, a gear, a gear shaft, an adjusting button, a nut, a disk spring cushion ring, etc. The adjusting button is twisted to drive the rack bar, the guide rod and a guide wheel assembly through the gear shaft and the gear to move up and down to reach a proper position. The adjustment is exact, flexible and reliable. The impact and the noise caused by sudden falling are avoided. The woodworking band saw can be widely used in the saw processing for wood and semi-finished products.

Description

Band saw

The utility model relates to woodworking machinery, the band saw of the saw processing that is used for timber of more clearly saying so.

Present band saw is mostly by base, frame, upper case, lower case, workbench and bearing thereof, motor, upper belt-wheel, bands for band strainer, the guiding parts etc. of belt wheel, bands for band, bands for band constitutes down.The height of guiding parts will be adjusted with the thickness of saw converted timber.Screw rod will be tightened outward by adjusting knob in its position, forces pressing plate that the guide post of guiding parts is pressed on the upper case inwall and locatees.This adjustment is more loaded down with trivial details, inconvenient operation.In addition, during adjustment, then want to unclamp pressing plate by adjusting knob earlier, guiding parts often descended suddenly the drop impact workbench and sent big noise because of deadweight this moment.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, and a kind of guiding parts with improved bands for band is provided; The adjustment of guiding parts is simple, and is easy to operate, can adjust accurate positioning continuously; And can not descend suddenly the drop impact workbench, also can not produce the band saw of noise.

In order to achieve the above object, the utility model band saw by base, be fixed on frame on the base, be fixed on upper case and lower case on the frame, be fixed on workbench and bearing thereof on the lower case, be installed in motor and control circuit thereof on the lower case, be installed in upper belt-wheel and bands for band strainer on the upper case, be installed in following belt wheel on the lower case, be installed in bands for band on the belt wheel up and down, the guiding parts etc. that is installed in the bands for band on the upper case constitutes.The guiding parts of bands for band is installed with guide wheel assemblies by the lower end and has gathering sill and the guide post of targeting port, be fixed on the guide pad in the targeting port that inserts guide post on the upper case, be fixed on the tooth bar of the gathering sill side of guide post, be arranged in gathering sill and tooth bar meshed gears, be fixed on gear centre and pass the threaded gear shaft in its end of targeting port of guide post, be installed in the adjusting knob that a small amount of relative displacement axially can be arranged on the gear shaft, be fastened on the nut of gear shaft end, be sleeved on that the disk spring washer between adjusting knob and nut constitutes on the gear shaft.When guide pad had up and down two, steering capability was better.

Disk spring washer has suitable elastic force, and it forces the left side of adjusting knob to be pressed on the lateral surface of upper case, keeps the location reliable.Simultaneously can not press too tightly again, can not be rotated adjusting by locking to avoid adjusting knob.Rotate adjusting knob, it is driven gear axle, gear, tooth bar successively, make tooth bar together with guide post and on guide wheel assemblies move up and down, get final product until the position that is parked in requirement, accurate positioning has realized continuous adjustment, impact and the noise of having avoided guide post to fall are suddenly operated also simple.

Task of the present utility model comes to this and finishes.

The guiding parts height of the utility model bands for band is adjustable continuously, and accurate positioning is reliable, and is simple to operate, has avoided unexpected impact and noise when falling, and the guide effect of bands for band improves greatly.It can be widely used in timber and the wooden half-finished saw processing.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further to describe.

Fig. 1 is the overall structure schematic diagram of embodiment 1.

Fig. 2 is the structural representation of guiding parts of the bands for band of embodiment 1.

Fig. 3 is that the A of Fig. 2 is to cutaway view.

Shown in Figure 1, embodiment 1 is made of base 1, frame 2, upper case 3, lower case 4, workbench and bearing 5 thereof, motor 6, upper belt-wheel 7, following belt wheel 8, bands for band 9, guiding parts 10 etc.

Fig. 2 and shown in Figure 3, the guiding parts of bands for band by the lower end be installed with guide wheel assemblies 11 and tape guide groove 12 and targeting port 13 guide post 14, be fixed on two guide pads 15 up and down on the upper case 3, the tooth bar 17, gear 18, gear shaft 19, adjusting knob 20, nut 21 and the disk spring washer 22 that are fixed on gathering sill 12 sides with screw 16 constitute.Gear shaft 19 and adjusting knob 20 can have a small amount of axially relative displacement with the combination of square tenon square hole.

The guiding parts adjustment of embodiment 1 bands for band is simple, and accurate positioning does not have and impacts and noise.It can be widely used in timber and the processing of half-finished saw thereof.
