In order to describe structure of the present invention and characteristics place in detail, below in conjunction with two preferred embodiments and conjunction with figs. explanation as after, wherein:

Fig. 1 is the side view of the present invention's first preferred embodiment;

Fig. 2 is the top view of the present invention's first preferred embodiment;

Side view when Fig. 3 is the present invention's first preferred embodiment sawing;

Fig. 4 is the subelement stereogram of the present invention's second preferred embodiment.

The specific embodiment

See also Fig. 1 to Fig. 2, the pipe cutting machine 10 that a preferred embodiment of the present invention provides, be in order to sawing one tubular workpiece 12, include a workbench 20, a saw arm 22, a cutter 24, a driven pulley 26, a driving wheel 32, an actuator 34, a trip 36, and a chaining 38.

This workbench 20 is to have a slide rail, is a microscler chute 201 at this, and this microscler chute 201 has a length direction L (see figure 2).

This saw arm 22 is to be articulated in this workbench 20.

This cutter 24 is to be arranged at this saw arm 22, and this cutter 24 has a feeding cut surface X, and this cut surface X is parallel with this length direction L of this microscler chute 201, and this cutter also can be driven by a sawing motor 241 and carry out to sawing.

This driven pulley 26, tool one rotation Y, this driven pulley rotatably is arranged at this workbench 20.

Described driving wheel 32 has and moves seat 28, one axostylus axostyle 30, and at least one runner 322, is two in these these runner 322 quantity:

This moves seat 28 is to utilize an adjustable fixture 281 and the microscler chute 201 that is arranged at this workbench 20 movably, and this fixture 281 is that a spiro connecting piece is to be placed through in this microscler chute 201 at this, and comprises a bolt and a nut.

This axostylus axostyle 30 is to be arranged at this to move seat 28, and this axostylus axostyle 30 includes a rotation Z, at least one link, is two links at this, and a worm gear 301; Wherein, this rotation Z is parallel and vertical with this cut surface X with this rotation Y, and this worm gear 301 is to be positioned at the position that differs from this link ends.

This two runner 322 is two connecting ends that are arranged at axostylus axostyle 30 respectively, and rotates with this rotation Z.

This actuator 34, be one to change material motor 34 at this, this commentaries on classics material motor 34 is to arrange to be connected in this and to move seat 28, and has an output shaft 341, this output shaft 341, this output shaft 341 includes a worm screw 343, this worm screw 343 and with worm gear 301 engagement of this axostylus axostyle 30, make this commentariess on classics material motor 34 can drive this two runner 322 via this axostylus axostyle 30 and rotate.

This trip 36 is to be arranged at this saw arm 22.

One end of this chaining 38 is to be arranged at this workbench 20, and other end of this chaining 38 is stuck in this trip 36 in order to collude.

Via said structure, when the user desires this workpiece 12 of sawing, need earlier this workpiece 12 to be placed on this workbench 20, and adjust by the position of mobile seat 28, make this workpiece 12 amplexiform described driving wheel 32 and driven pulley 26 (as Fig. 1) simultaneously; Then, the user opens this sawing motor 241, and downward this saw arm 22 (as Fig. 3) of switching, this cutter 24 can contact and this workpiece 12 of sawing, at this moment, cooperate this commentaries on classics material motor 34 to drive this workpiece 12 rotations via this driving wheel 32, and rotate by the collocation of driven pulley 26, this workpiece 12 constantly conversion position contacts this cutter 24, up to fully by till sawed-off.

In the process of sawing, the user can collude this chaining 38 and be stuck in this trip 36 (as Fig. 3), provide tension force to resist the active force of this

workbench

20 and 22 torque spring (not shown) of saw arm by this chaining 38, it is motionless that this saw arm 22 and this cutter 24 can be kept fixed-site, with make things convenient for sawing work continue carry out.

In the process of sawing, because the user need not to continue fixedly saw arm 22 of the application of force, also need not to rotate and fix this workpiece 12 with hand, improve the convenience on using greatly; Drive workpiece 12 rotations swimmingly and change material motor 34, more can make the section of workpiece 12 more smooth.

In addition, this changes between the output shaft 341 and this axostylus axostyle 30 of material motor 34, also can use bevel gear, helical gear or other equivalent mechanical organs to drive in fact, can bring into play effect too.

Based on spirit of the present invention, this pipe cutting machine also can be changed on structure in fact, please consult Fig. 4 again, the pipe cutting machine 40 that the present invention's second preferred embodiment provides has a workbench 42 equally, one saw arm (not shown), one cutter (not shown), one driven pulley (not shown), one moves seat 44, one axostylus axostyle 46 and an actuator 50, its difference is, 40 of this pipe cutting machines arrange a driving wheel 48 that is fixed on this axostylus axostyle 46, and this axostylus axostyle 46 have pull the end 461, this cross section of pulling end 461 is to be non-circular, and 40 of this pipe cutting machines do not possess the worm gear of previous embodiment and change the material motor; Among present embodiment, this cross sectional shape of pulling end 461 is hexagon, this actuator 50 is a ratchet spanner 50, the user can utilize this ratchet spanner 50 to be sleeved on this and pull end 461, drive this axostylus axostyle 46 rotates via this ratchet spanner 50 of unidirectional turn, that is driving this driving wheel 48 rotations synchronously, driving wheel 48 will drive workpiece 12 backward rotation by frictional force this moment, and reach this driving wheel 48 drives workpiece 12 rotations with manual mode effectiveness.

The above, only be detailed description and the diagram of preferred embodiment of the present invention, all closing in the embodiment of the spirit variation similar with it of the present patent application claim, all be contained in the category of the present invention, anyly be familiar with this operator in the field of the invention, can think easily and variation or modify all can be encompassed in the claim scope of this case.
