Abstract
The utility model relates to a hand carried sweep saw which comprises a machine casing, an electrical motor, a gear, a roller wheel, a reciprocating lever and a saw blade, wherein the gear is directly engaged through a bearing seat with a rotor of the electrical motor, which passes the rotation of the rotor to the roller wheel sheathed on a small shaft; the roller wheel is sheathed in a sliding groove of the reciprocating lever which is connected to the sliding bearing seat, and the sliding bearing seat is connected to a bearing retaining flange of the machine casing; the reciprocating lever drives the saw blade fixed on the reciprocating lever by threads to reciprocally move, and the shape of the reciprocating lever is in a slice sheet shape.
Description
The utility model relates to a kind of electric tool, particularly a kind of small portable sweep-saw that is used for curvilinear cut.
Sweep-saw is various in style, is widely used in the curvilinear cut of timber, sheet metal component.But because the existing sweep-saw directions of motion that adopt columniform reciprocating lever to fix saw blade more, reciprocating lever and the frictional force of fixing between its plain bearing housing are bigger, melt on the cabinet in order to the fixing bearing fixed seat of plain bearing housing can producing a large amount of heats under the heavy load effect, cause the plain bearing housing position unfixing, thereby the instability that causes the saw blade motion, cutting effect is undesirable, and the danger of saw blade fracture easily takes place.
The purpose of this utility model provides a kind of reciprocating lever and fixes that frictional force between its plain bearing housing is less, the plain bearing housing fixed-site is good, the sweep-saw of saw blade motion stabilization.
The utility model comprises that casing 1, motor 2, gear 3, roller 4, reciprocating lever 5 and saw blade 6 form, and gear 3 directly mesh by the rotor 8 of bearing block 7 with motor 2, and the rotation of rotor 8 is passed to the roller 4 that is enclosed within on its little 9; Roller 4 is enclosed within the chute 12 of reciprocating lever 5; Reciprocating lever 5 is connected on the plain bearing housing 11, and plain bearing housing 11 is connected on the bearing fixed seat 10 on the casing 1; Reciprocating lever 5 drives and moves reciprocatingly by screw thread 13 saw blades 6 fixed thereon; Reciprocating lever is lamellar.
Accompanying drawing 1 structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of the lamellar reciprocating lever that the utility model adopted.
Below in conjunction with schematic diagram the utility model is described further.
The utility model mainly is made up of casing 1, motor 2, gear 3, roller 4, reciprocating lever 5 and saw blade 6.Wherein, gear 3 directly mesh by the rotor 8 of bearing block 7 with motor 2, and the rotation of rotor 8 is passed to the roller 4 that is enclosed within on its little 9.Roller 4 is enclosed within the chute 12 of reciprocating lever 5.Because the bearing fixed seat 10 on the casing 1 has limited the displacement of reciprocating lever 5 in other direction by plain bearing housing 11, and the rotation that makes roller 4 changes into reciprocating lever 5 with respect to the pumping of plain bearing housing, and this motion is remained on the same axis.Reciprocating lever 5 drives move reciprocatingly by screw thread 13 saw blades 6 fixed thereon and achieve the function of curvilinear cut.
Compared with prior art, because the utility model has adopted laminal reciprocating lever 5, reduced the friction of itself and plain bearing housing 11 effectively, even under long heavy load effect, can not cause the fusing of the bearing fixed seat 10 on the cabinet 1 yet, thereby the motion that has guaranteed reciprocating lever 5 is all the time on same axis, and then guaranteed the stability that saw blade moves, and improved the durability of sweep-saw, prolonged its service life.Simultaneously, because laminal reciprocating lever processing technology is simple, thereby reduced production cost largely.
