Abstract
The utility model discloses a dc type triangle grinding and polishing machine, which comprises a shell with a handle. A bottom board is arranged at the bottom of the shell; a piece of sand paper covers the lower surface of the bottom board; the shell is connected with the bottom board through a front connecting frame and a rear connecting frame with elasticity; an eccentric gear is arranged above the bottom board; a rotating shaft arranged in the shell is fixed into an eccentric hole of the eccentric gear; the shell is internally provided with a motor; and a motor gear engaged with the eccentric gear is arranged on the output shaft of the motor. A cell box is inserted at the rear end of the shell; a lock catch capable of being buckled with the cell box is movably arranged at the rear side of the handle of the shell; and a return spring is arranged at the upper end of the lock catch. In the dc type triangle grinding and polishing machine, the transmission ratio of the gear is so improved that the grinding efficiency is greatly improved; the cell box, arranged at the rear end of the shell, can be conveniently disassembled and assembled, and is also safely operated; the cell box, arranged at the rear end of the shell can be conveniently disassembled and assembled, and a section of long power line is also omitted when the dc type triangle grinding and polishing machine operates. The dc type triangle grinding and polishing machine has the advantages of novel design, simple structure and low cost and is convenient to operate.
Description
Technical field
The utility model relates to a kind of electric hand tool, specifically a kind of triangle disk sander of single flow.
Background technology
Existing triangle disk sander, basic structure comprises casing, base plate, be arranged on drive motors in the casing and drive base plate by gear drive and rotate and carry out sand milling, but the gear transmission structure of existing disk sander is comparatively complicated, production cost is higher.Some triangle disk sander needs subsidiary one section long power line, very trouble in use in addition.Patent Office of the People's Republic of China is disclosed on May 23rd, 2007, Granted publication number is " the rechargeable direct current electric angle grinder " of " CN2902574 ", it comprises the detachable power brick, motor, switch module, housing, gearbox, working head, motor is fixed on the housing, described gearbox comprises head capsule, pinion shaft, bevel pinion, bevel gear wheel, the output main shaft, pinion shaft is arranged on the head capsule by the bearing of both sides, bevel pinion is fixed on the pinion shaft, the output main shaft is fixed with bevel gear wheel and is arranged on the head capsule by bearing, bevel gear wheel and bevel pinion engagement, working head is fixed on the output main shaft, and motor is connected with pinion shaft by flexible coupling.Though this structure has been omitted power line, because its gear drive complex structure, parts partly are many, so manufacturing cost is very high.
The utility model content
The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, for people provide a kind of modern design, simple in structure, single flow triangle disk sander that cost is low, easy to operate.
Technical solution adopted in the utility model is for achieving the above object: this single flow triangle disk sander comprises the casing that has handle, bottom at casing is provided with base plate, lower surface at base plate is coated with sand paper, link to each other with rear connecting frame by link before the rubber-like between casing and the base plate, described base plate top is provided with eccentric gear, the rotating shaft that is installed in the casing is fixed in the eccentric orfice of eccentric gear, be provided with motor in the described casing, the motor gear with the eccentric gear engagement is installed on the output shaft of motor.
Described casing rear end is fitted with battery case, is movably installed with the snap close that can interlock with battery case at the handle rear side of casing, is provided with back-moving spring in the upper end of snap close.
Be provided with the spring part relative in the described casing with battery case.
In the described housing bearing is installed, the endoporus of bearing is fixed in described rotating shaft.
The utility model is by being installed in the motor gear transmission eccentric gear on the motor, and the drive base plate rotates and carries out sand milling, has improved the gearratio of gear, and sand milling efficient is greatly improved.Be arranged at the battery case of casing rear end, also needn't attach one section long power line in the time of not only easy accessibility, and work.Has modern design, advantage simple in structure, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model base plate.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of single flow triangle disk sander, and it comprises the casing 2 that has handle 1, is provided with base plate 9 in the bottom of casing 2, lower surface at base plate 9 is coated with sand paper 11, links to each other with rear connecting frame 14 by preceding link 8 between casing 2 and the base plate 9.Link 8 and rear connecting frame 14 are made by resilient material before described, and as plastics, nylon etc., so base plate 9 can move relative to casing 2.In the described housing 2 bearing 12 is installed, in the endoporus of bearing 12, is installed with rotating shaft 6.Therefore described base plate 9 tops are provided with eccentric gear 13, and rotating shaft 6 is fixed in the eccentric orfice of eccentric gear 13, and when eccentric gear 13 6 rotations around the shaft, base plate 9 is quick rotation thereupon also, carries out sand milling work by sand paper 11.Be provided with motor 5 in the described casing 2, the motor gear 10 that meshes with eccentric gear 13 is installed on the output shaft of motor 5, can directly drive eccentric gear 13, improved the gearratio of gear, sand milling efficient is greatly improved by motor gear 10.
Described casing 2 rear ends are fitted with battery case 15, are movably installed with the snap close 16 that can interlock with battery case 15 at handle 1 rear side of casing 2, are provided with back-moving spring 17 in the upper end of snap close 16.When battery case 15 inserts casings 2, under back-moving spring 17 restoring force effects, snap close 16 automatically with battery case 15 on the lock hole fastening, avoid battery case 15 disengagements.This battery case 15 links to each other with motor 5 by socket 4 in the casing 2 and 3 backs of the switch on the casing 2, after battery case 15 is installed, can control the keying of motor 5 by switch 3.Be provided with the spring part 7 relative with battery case 15 in the described casing 2, when pulling snap close 16 and removing battery case 15 lockings, under spring part 7 restoring force effects, battery case 15 ejects automatically, has made things convenient for the replacing battery.Be arranged at the battery case 15 of casing 2 rear ends, also needn't attach one section long power line in the time of not only easy accessibility, and work, have modern design, advantage simple in structure, easy to operate.
