Abstract
The utility model relates to an electric hand-held curved saw which is used for cutting lumber, plastics, metal, etc. and is especially suitable for being used by woodworkers and widely used in industry and families. The utility model is composed of a motor arranged in an outer housing, a switch, a transmission device, a reciprocating lever, a cutter blade, a bottom board and a cover cap, and a stator and a rotor of the motor are positioned by a front and a rear end covers, connected with each other into a whole and arranged in the outer housing. The abuse that inaccurate positioning of the motor is caused by big volume and easy deformation of the outer housing is avoided, and the evenness degree of airgaps of the stator and the rotor of the motor can be ensured by the front and the rear end covers. The utility model has the advantages of reducing the vibration and the noise of the curved saw, extending service life, increasing economic benefit and lowering labour intensity; the utility model is an electrical tool which is used conveniently and limberly and is especially suitable for being used in families.
Description
The utility model relates to a kind of electric tool, and particularly portable sweep-saw is used to cut timber, plastics, metal etc., is suitable for carpenter, decoration industry and family especially and is extensive use of.
If existing sweep-saw DYN dynamic its all big, the Heavy Weight of volume, can not carry, small-sized sweep-saw mostly is hand again.
What the patent No. 94219248.6 " sweep-saw " provided also is a kind of portative electric tool, but motor is not an overall structure, because the distortion of shell will influence the precision of motor, so also there are shortcomings such as vibration is big, noise height.
The purpose of this utility model is to provide a kind of sweep-saw, and its vibration is little, noise is low, portable, easy to use, long service life.
The utility model is achieved by the following scheme: sweep-saw is made up of motor, power supply, speed-regulating switch, gear-box, transmission device, reciprocating lever, blade and base plate, the cover cap installed in the enclosure, and the stator and rotor of motor are located by forward and backward end cap and connect installation more in aggregates in the enclosure.
Fig. 1. structural representation of the present utility model.
Fig. 2. the electric machine structure schematic diagram.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Shell (2) is cast into by plastics, go up by each part fixedly the left and right two halves shell of cavity and reinforcement form.Cover cap (13) is made for transparent plastic, is configured on the shell (2) with tongue and groove.
Base plate (14) is screwed in the bottom of shell (2), is used for the location.Speed-regulating switch (1) knob is contained in the preceding top of shell, is convenient to the hand adjustment joint.Power switch (3) is contained in the handle cavity of shell (2) upper end, is convenient to hand operated.
Reciprocating lever (12) is long rectangle, and upper and lower fixing by two oiliness bearings (5), bearing (5) is fixing by gear-box (4).Blade (15) is screwed end in reciprocating lever (12) by chuck.
Gear-box (4) is a metalwork, is fixed in the shell (2), and one end through hole is metallic sintered products bottom bracket axle (7) fixedly.
The axis (8) of gear (6) by being pressed into its endoporus is engaged in the bottom bracket axle (7), in order to carry out gear (6) location and to rotate.
Forward and backward end cap (11), (16) are positioned on stator (18) iron core by seam, and rotor (19) is supported by forward and backward end cap (11), (16) bearing chamber by bearing (20).Screw passes forward and backward end cap (11), (16) and stator (18) iron core and connects into whole motor (17).
Whole motor (17) is fixed in the cavity of shell (2), and gear-box (4) is screwed on the drive end bearing bracket (11) of motor (17).
Motor (17) shaft end gear and gear (6) engagement, roller (9) is enclosed within on the axle (10), and axle (10) is pressed into gear (6).And roller (9) external diameter constitutes transmission device movingly on reciprocating lever (12).
All part assembles, and with screw left and right two halves shell is linked to be integral body.
During use, connect power supply power turn-on switch (3), motor (17) drives roller (9) by gear (6) and rotates, because the wobbler action of roller (9), the rotation of roller (9) drives reciprocating lever (10) moving linearly, thereby drive blade (15) and make upper and lower rectilinear motion, realize processing workpiece.
Regulate speed-regulating switch (1) or select different blade (15) for use, the workpiece of different materials such as timber, plastics, metal is processed with regard to available different speed.
The utility model is compared with prior art: because the stator and rotor of motor are not to be directly installed on shell In, but connect into whole motor by forward and backward end cap location with stator and rotor, with integrally-built Motor is installed in the cavity of shell, so just can avoid making motor because of big yielding the bringing of enclosure volume Locate coarse drawback. The aspect is because adopting integrally-built motor in addition, and motor stator and rotor air gap is equal Evenness can be guaranteed by forward and backward end cap, because the raising of motor positioning accuracy makes the vibration of motor rotation Little, noise is low, thereby also reduced vibration and the noise of sweep-saw. Prolonged service life, improved Economic benefit is the electric tool that can carry, and is therefore easy to use, flexible, especially suitable family Use, reduce labor intensity.
