Description
The utility model relates to a kind of guide type air impeller grinder.
Traditional portable sander is with the vane type motor kind of drive, but impeller and cylinder interbody spacer must closely just can obtain transmission efficiency preferably, when manipulating, because single-point is implemented polish process, can apply a bending moment by center roller, make impeller rub, shake when rotating at a high speed and between cylinder and reduce torsion, life of components is reduced greatly, fault rate is high.For this reason, grinding machine structure is made into directly to act on turbine leaf (establishing the wheel blade of "＜" shape) by gas port ejection gases at high pressure, through stopping of air-flow retaining wall, generation moment reaction force promotes turbine again, make axle when rotating at a high speed, still have high torque transmission, do not stop operating when making work, to avoid the numerous inconvenience and the puzzlement that bring to the user, to have improved production efficiency because of load increases.But known guide type air impeller grinder produces the unbalanced stress of guided turbine, and its operating accuracy and service life are still restricted.
For this reason, the purpose of this utility model is to provide a kind of improved guide type air impeller grinder, and it can overcome above-mentioned shortcoming, the rotation steadily and at a high speed of its axle, and assembly is easily processed and is assembled, and cost is low.
For reaching aforesaid purpose, the utility model changes the airflow hole of six five equilibriums offered in the air-flow retaining wall to be established to auxilliary stream piece, and on end face, be provided with a groove and an inclined-plane, be divided into a backflow air flue after making air communication cross turbine, via the bounce-back of groove boosting turbine again, make the rotation of turbine more steady, reduction of speed compares prior art still less.Also make the thrust of turbine dual-side more average in addition, thus more balanced when making turbine drive axle.Also have, the turbine both sides have installed shield bearing and ball bearing, and they form simply supported beam supporting with the bearing of axle front end, and axle is difficult for deflection and wearing and tearing when working like this, has prolonged life of components.
A kind of guide type air impeller grinder comprises: a ring set, a pneumatic fittings, cylinder chamber's jet thrust, two bearings, two dust rings, guided turbine, auxilliary stream piece, air-flow retaining wall, sleeve and axle; Wherein, the end face of cylinder chamber's jet thrust is provided with an oblique through hole, is provided with several oblique groove simultaneously, and the other end is provided with a gas collection dike ring that is higher than anchor ring; Described guided turbine is provided with several at the outer shroud place＜type leaf groove, is used for direct air-guiding and turns to; Dust ring is provided with ring of numbers choke dirt groove at anchor ring, and establishes a groove on the side, and groove side two planes are not contour; Described auxilliary stream piece has gas channel and six shunting projections of six five equilibriums, and each is shunted projection and is provided with " fourth " type folding air drain and an inclined-plane; Described air-flow retaining wall is big or small two caliber shapes, establishes the groove of five five equilibriums in the end.When air-flow is imported by jet joint, jet via cylinder chamber's jet thrust sprays to guided turbine, and warp＜type leaf groove and produce rotation torque, air-flow turn to and the boosting guided turbine through the shunting of auxilliary stream piece again, make two side-thrust differences of guide vane wheel littler, reach the effect of high-speed smooth rotation.

One cylinder chamber's jet thrust 3 is provided with several cascade rings 29, and is provided with an inclined hole shape jet 31 at the end face of cascade ring 29, becomes an oblique angle with axial line; Be provided with a flange 32 in addition in the end.
One guided turbine 5 is provided with a through hole 33 at the center; Between inside and outside ring-type portion 35,36, be provided with several "＜" that is 90 ° shape＜type blade grooves 34.
It is tabular that dust ring 41,61 is disk, which is provided with several choke dirt grooves 42,62, just can make a side be provided with concave ring groove 43,63 in.
One assists stream piece 7, which is provided with the shunting projection 72 of six five equilibriums, establishes one at an end of shunting projection 72 and is " fourth " shape folding air drain 74 and an inclined-plane 76, forms a distributary division 75.
One air-flow retaining wall 8 has a through hole 81 to pass two ends that vary in size, and is provided with screw thread 82 in the one end, is provided with the groove 80 of five five equilibriums at the other end.
One sleeve, 9, one ends are provided with scalene cone 91, and it is one horn-like terminal 92 that the opposite end is provided with, and are provided with a through hole 93 along central axis.
One axle 10 respectively is provided with ladder 44,45 at end face, and the end of ladder 44 is provided with a screw thread 46, at ladder 45 places of the other end one hole 47 is arranged, for the emery wheel locking.
The compound mode of each part is as follows in the said structure:
See also figure two, be section plan of the present utility model, the central through-hole 93 of sleeve 9 is inserted in axle 10, and through hole 81 centers along air-flow retaining wall 8 embed again.In addition, auxilliary stream piece 7 is embedded by the other end of air-flow retaining wall 8, just is embedded the draw place at air-flow retaining wall 8, and sleeve 9 ramps 91 also are embedded on the nose end of auxilliary stream piece 7, makes sleeve 9 can locate symmetry place, axle center.Ball bearing 6, dust ring 61, guided turbine 5, dust ring 41 and ball bearing 4 are embedded along axle 10 axial lines, above-mentioned each part is fixed on the ladder 44 of axle 10 with hexagonal (hexagon)nut 50; Then the cascade ring 29 of cylinder chamber's jet thrust 3 is aimed on the ring 28 of pneumatic fittings 2 fixingly, the nipple 23 with this pneumatic fittings 2 is fixed on the screw thread 82 of air-flow retaining wall 8 again.One pin, 14 pin-and-holes 21 by ring set 1 run through fixing; O type ring 11,12,13 embeds respectively in the scrobicular ring 17,18 and groove 19 of ring set 1, constitutes to make the unlikely leak-proof device that leaks of air pressure.Ring set 1 is socketed in an end of pneumatic fittings 2, just allows pin 14 be inserted in the half-moon-shaped groove 25 of pneumatic fittings 2, become the release knob of an air pressure stream.
By the guide type air impeller grinder that said structure is formed, its operation principle is as follows:
