Abstract
The utility model relates to a position-changeable triangular grinding machine which is composed of a motor, a bevel transmission gear, a main shaft, a swing supporting frame and a triangular grinding head, wherein the triangular grinding head is composed of a rotating disk, a triangular tray, a triangular rubber plate and a triangular bristle plate. The rotating disk is in rotating connection with the triangular tray, and is connected with an eccentric block bearing at the lower end of the main shaft; the triangular rubber plate and the triangular bristle plate are integrally connected with the triangular tray. The utility model has the advantages of low replacement frequency of the grinding head, no waste phenomena, low cost and long service life.
Description
The utility model relates to a kind of electric tool, particularly a kind of electric sander of the usefulness of polishing.
Existing triangle sander is by casing, motor, the umbrella shape travelling gear, main shaft, swinging mounting and triangle sanding bistrique are formed, motor links to each other with main shaft by travelling gear, main shaft links to each other with casing by swinging mounting, make main shaft under motor-driven, finish wobbling action simultaneously, the swinging mounting lower end links to each other with triangle sanding bistrique, and the main shaft lower end flexibly connects by the pallet of eccentric block bearing and triangle sanding bistrique, make main shaft under the motor rotating drive, rotate at a high speed, simultaneously under the swinging mounting effect, do high speed swinging again, do high speed swinging work thereby drive triangle sanding bistrique.But in the existing triangle sander, triangle sanding bistrique is made up of triangle pallet, triangle rubber slab and triangle thorn hair plates one, swinging mounting links to each other with pallet in the triangle sanding bistrique, make triangle sanding bistrique not have indexing function like this, can only be when it uses with the position at an angle as the work bistrique, after wearing and tearing, can only change a new triangle sanding bistrique, waste is big, the use cost height, and service life is short.
The purpose of this utility model is exactly to provide a kind of cost low in order to address the above problem, service life big leap ahead indexable triangle sander.
Technical solution of the present utility model:
A kind of indexable triangle sander, it is made up of motor, umbrella shape travelling gear, main shaft, swinging mounting and triangle sanding bistrique, it is characterized in that triangle sanding bistrique stings hair plates by rotating disk, triangle pallet, triangle rubber slab and triangle and forms, rotating disk is that rotational positioning is connected with the triangle pallet, rotating disk links to each other with the eccentric block bearing of main shaft lower end, and the triangle rubber slab is connected with triangle pallet one with triangle thorn hair plates.
The utility model changes triangle sanding bistrique into the indexing type structure first, so in use, after the working head wearing and tearing at an angle, can carry out transposition action, make the working head at another angle carry out work, a triangle sanding bistrique then of the present utility model can be equivalent to existing three bistriques, so significantly reduced the turnover rate of bistrique, eliminate waste, use cost reduces greatly, service life big leap ahead.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the utility model still is made up of motor 1, umbrella shape travelling gear 2, main shaft 3, swinging mounting 4 and triangle sanding bistrique 5, characteristics of the present utility model are that triangle sanding bistrique 5 is made up of rotating disk 6, triangle pallet 7, triangle rubber slab 8 and triangle thorn hair plates 9, rotating disk 6 is connected for rotational positioning with triangle pallet 7, rotating disk 7 links to each other with the eccentric block bearing 10 of main shaft 3 lower ends, and triangle rubber slab 8 is connected with triangle pallet 7 one with triangle thorn hair plates 9.
In the utility model, rotating disk 6 is a disc, its upper surface middle part has a bearing chamber 11, be used for closely connecting with eccentric block bearing 10, its lower surface has a circle boss 12, correspondingly triangle pallet 7 upper surfaces have the seam 13 that a circle matches, they coincide and link together, the bottom surface of rotating disk 6 lower surfaces one circle boss 12 evenly is provided with three steel ball holes 14, be equipped with steel ball 15 and spring 16 thereof in each hole, correspondingly the end face at triangle pallet 6 upper surfaces one circle seam 1 is provided with six location pits 17 that match with steel ball 15, makes rotating disk 6 realize that with pallet 7 indexable formula is connected.
When the utility model uses, motor 1 drives main shaft 3 rotation at a high speed by umbrella shape travelling gear 2, main shaft 3 is done high speed swinging again simultaneously under swinging mounting 4 effects, this high speed swinging makes triangle sanding bistrique 5 make high speed swinging by eccentric block bearing 10, carries out sanding operation.After the working head wearing and tearing at an angle of front end, only need to rotate triangle pallet 7, then it realizes transposition action under steel ball 15 between rotating disk 6 and the pallet 7 and spring 16 effects thereof, make the working head at another angle enter duty, can carry out new polishing work, use and transposition are all very convenient.
