Description

Portable grinding, polishing, drilling and cutting machine

The present invention relates to a kind of grinding, polishing, drilling and cutting machine that utilizes the hand held electric drill principle to increase part device.

Usually polishing on a small scale, polishing, boring, plain grinding is employed to be four kinds of hand held electric tools; Hand electric polisher, hand-held sander, hand held electric drill and hand-held abrasive machine.And unvanquishable weakness is respectively arranged from the structure and the device of sanding machine and sander.1, existing hand electric polisher is not have buffer structure, can't compensate the operating pressure of emery wheel automatically, only leans on operator's eyesight and feels to come the grinding bossing, and therefore the tortuous uneven plate face of grinding is helpless accurately.2, existing sander is with the emery cloth polishing, can't accomplish and will reach high accuracy with this device polishing metal material.In order to address this problem, my patent of invention " the abrasive wheel polisher for big stainless steel plate " (patent No.: 88108749.1) propose the buffering bistrique, propose to utilize emery cloth to lash the machine processing again and polish the small texture that the emery wheel of back generation is passed by, but this processing complex structure, operate take a lot of work, time-consuming uneconomical again.And this device utilizes electrical motor gearshift to solve this difficult problem with the low speed grinding.

The present invention seeks to utilize the hand held electric drill principle to increase part device, make it have boring and plain grinding, the tortuous uneven plate face of grinding does not equably damage on every side the plane and polishes soldering and go out, and polishes accurately and four kinds of functions such as polishing.

The present invention is achieved in that model of the present invention, rated voltage, input power, rated speed are all identical with hand held electric drill, and appearance similar, increase dust excluder now, a pair of high gear (6) (4) increases a speed change and pulls out wooden fork, change the spline output shaft again, increase buffering bistrique etc., and each spot size size adapts to its function fully according to two kinds of specifications design of electric hand drill watt level.

Apparatus of the present invention have been compared following characteristics with existing four kinds of similar hand held electric tools:

1, this device has high and low rotating speed, utilizes high rotating speed polishing, polishing, plain grinding; Utilize slow-speed of revolution boring, grind or polishing.

2, bistrique (ramming head) has buffer structure, regulates the operating pressure of bistrique (ramming head) automatically, thereby utilizes high and low rotating speed to reach the purpose of high accuracy polishing and polishing.

3, this device output shaft is a splined shaft, is connected with each functional part spline or is fastenedly connected.It is very simple to change parts when needing to change function, only just can locate by a pin, or only just can fix with a Luo Ding.

4, since this device possess mill, four kinds of difference in functionalitys such as throw, bore, cut, so very economical again easy to use.

Below with reference to accompanying drawing invention is described in further detail.

Fig. 5, three melon dop auger spindles (22) and circular cone sleeve (20) (auger spindle) structural map.

With reference to Fig. 1, motor power is by master (No. 5), and (No. 6) driven gear (No. 4) (No. 3) rotation spline output shaft (7) spreads out of.

With reference to Fig. 2, sanding machine grinding wheel head structure critical piece is that spline connects dish (8), buffer spring (9) is contained in spline and connects on dish one end, tapered wheel sheet (11) is fixed on spline by taper sheath (10) with 4 M6 Luo Ding and connects on another termination of dish (8), form sanding machine bistrique Fig. 2), bistrique (Fig. 2) connects dish (8) by spline and is sleeved on the spline output shaft (7) and locatees through straight pin.

During work, connect power supply and start motor, rotary power is by main (No. 5) (No. 6), driven gear (No. 3) (No. 4), spline output shaft (7), spline connect dish (8) taper sheath (10) and drive grinding wheel (11) rotation, and can be according to technological requirement, change main, the driven gear position of engagement, obtain two different rotating speeds.

Spline output shaft (7) laterally has a locating hole (15), same direction spline connects 10 millimeters slotted holes (12) on the dish (8), with alignment pin bistrique partly is positioned on the spline output shaft (7), rotate thereupon, and can in 10 millimeters scopes, utilize the elastic force of buffer spring (9) to move axially by slotted hole (10), reach the effect of buffering and compensatory pressure.The feeding size is finished by manpower.Use 80 during polishing ^#, 240 ^#(available 300 ^#) tapered wheel, utilize high rotating speed (4) (6) the processed place of grinding successively, to change the slow-speed of revolution (5) (3) then and grind, fineness reaches △ ₉More than.

With reference to Fig. 3, it is to paste knot in one with circular industrial felt that felt connects dish (14), and dismounting bistrique taper sheath (10) connects dish (14) to felt and is fixed on spline with 4 sieve's M6 silks and connects on the dish (8) and just form polishing machine during use, uses homemade abrasive material fineness to reach △ ₁₃-△ ₁₄
