Abstract
The utility model relates to a multifunctional minisize grinding machine, being applicable for the use of the processing of small-size work-pieces in industry and being used as appliances for dentistry and face care. The primary structure of the grinding machine is composed of a pressure regulating and pressure stabilized power supply, a grinder, a grinding head, a high-speed direct current electric motor, a spin device and a rotary shaft, wherein, the high-speed direct current electric motor is arranged in the motor casing of the grinder; the rear of the electric motor is provided with a rear casing and the front is provided with a front housing; the spin device is composed of a front housing, a pressure spring, a conic sleeve, a radial ball bearing and steel balls; the rotary shaft is composed of a spline sleeve and a transmission shaft. The spline sleeve is connected with an electric motor shaft. The transmission shaft is matched with the spline on the exterior of the spline sleeve. The grinding rod of the grinding head is arranged in the transmission shaft, which exceeds the steel ball position.
Description
The utility model relates to a kind of multi-function miniature grinding utensil, be suitable for the processing of industrial miniature workpiece and make beauty treatment, dental instrument usefulness.
Used process equipment such as plain grinding in the industrial production, polishing at present, abrasive machine, drilling machine volume be big, heavy, move, carry inconvenience, operates dumbly, is unsuitable for the processing of industrial miniature workpiece.Drilling tool volumes such as dental drill at health system are also bigger, move, operate dumb.These drillings, the general working voltage of grinding tool are higher, and portable use is very dangerous.
The purpose of this utility model provides a kind of multifunction micro sharpener, and is simple in structure, can adjust required rotating speed arbitrarily, safe and reliable, applied widely, and volume is little, in light weight, be easy to carry.
The multifunction micro sharpener takes following scheme to realize: the multifunction micro sharpener mainly is made of power suppling part branch, sharpener two parts.Power suppling part is divided into three sections voltage-regulation voltage-stabilization direct currents with power supply, but step-less adjustment voltage and rotating speed.Sharpener is made of high speed direct current generator, shell, spinning apparatus, turning cylinder, tapered sleeve, bistrique.The sharpener shell has motor casing, and the motor casing rear portion is a rear casing, and the motor casing front portion is a front casing.The high speed direct current generator is contained in the sharpener motor casing, and the dc motor power termination is housed in the rear casing, is connected with power line, attaching plug, so that patch mutually with the voltage-regulation voltage-stabilization power supply.Spinning apparatus is assemblied in the front casing position, is made of front casing, stage clip, tapered sleeve, radial ball bearing, steel ball.Turning cylinder is made of spline housing, power transmission shaft.Spline housing is connected with motor reel, places the front casing middle part, has splined hole on the power transmission shaft, and matching with pattern chain cover external spline is connected.The steel ball of spinning apparatus is equipped with in the power transmission shaft top, its outer tapered sleeve that is with, the stationary fit of power transmission shaft front end is on radial ball bearing, spacer ring is equipped with in the radial ball bearing below, between spacer ring and the tapered sleeve stage clip is housed, and the mill bar is contained in the power transmission shaft, drive turning cylinder simultaneously and steel ball moves, because the effect of tapered sleeve and steel ball, compress and loosen the mill bar, thereby reach the flexible purpose of packing into and taking out.
The multifunction micro sharpener aspect dynamo-electric by microminiaturization design design, in light weight, compact conformation, scientific and reasonable, be easy to carry, flexible operation, safe and reliable, be equipped with three sections voltage-regulation voltage-stabilization dc sources, but step-less adjustment voltage and rotating speed.This sharpener is a kind of mechanical rotation principle of utilizing, be equipped with bistrique and specific purpose tool, utilize low speed or rotation at a high speed, have multiple function, small-sized object is carried out eurypalynous processing and human body skin and dentistry improve looks, make it the purpose that reaches smooth, smooth.
The utility model is described in further detail below with reference to accompanying drawing
Fig. 1 is that the multifunction micro sharpener is made of power suppling part branch, sharpener two parts, sharpener has motor casing (3), the high speed direct current generator is contained in the motor casing, rear casing (2) is equipped with at the motor casing rear portion, attaching plug, power line (1), be connected on the motor wiring device in the rear casing, supply with the dc motor constant voltage dc source, but the power supply step-less adjustment voltage of supply is regulated dc motor speed with this.Motor casing (3) front end is equipped with front casing (12), adopts nut (6) to be fitted in the motor casing front end.Nut is used for fixing front casing, regulates gap between tapered sleeve and the steel ball, enamel plate (4) is housed between front casing and the motor casing makes positioning baffle.Spline housing (7) motor reel interior with placing motor casing (3) is connected, fixing by cylinder screw (5), spline housing (7) cooperates with splined hole on the power transmission shaft (8) by the spline connected mode, be equipped with on impartial three small ball bearings (10) of arranging the power transmission shaft top, the stationary fit of power transmission shaft front end is on radial ball bearing (15), spacer ring (14) is equipped with in radial ball bearing (15) below, pressure that stage clip (13), stage clip produce is housed between spacer ring and the tapered sleeve does not act on up and down on two radial bearings, and be pressed on the tapered sleeve.Circlip (16) is contained in power transmission shaft front end radial ball bearing (15) outside, locatees to bearing.Bistrique (17) is made of mill bar, bistrique, and bistrique can be made all size and variform bistrique respectively according to instructions for use.Power transmission shaft (8) has mesopore, and the mill bar is inserted in the power transmission shaft mesopore, surpasses the rigging position of steel ball (9).The mill bar can be processed into triangle, makes clamping firm.Spinning front casing (12) time extruding stage clip (13) during use, stage clip compress or loosen and promote tapered sleeve and compress or loosen steel ball, can compress or loosen the mill bar, and the mill bar can conveniently be packed into or take out.Thereby driven by motor turning cylinder high speed rotating drive mill bar bistrique rotates with grinding, drilling workpiece at a high speed or is used for beautifying skin, dentistry reconditioning.
Claims (3)
1, a kind of multifunction micro sharpener, have voltage-regulation voltage-stabilization power supply, sharpener, bistrique, it is characterized in that the high speed direct current generator is contained in the sharpener motor casing, rear casing is equipped with at the motor casing rear portion, the dc motor power termination is housed in the rear casing, and the motor casing front portion is a front casing; Spinning apparatus is assemblied in the front casing position, is made of front casing, stage clip, tapered sleeve, radial ball bearing, steel ball; Turning cylinder is made of spline housing, power transmission shaft; Spline housing is connected with motor reel, has splined hole on the power transmission shaft, match with the spline housing external spline and to be connected, the steel ball of spinning apparatus is equipped with in the power transmission shaft top, its outer tapered sleeve that is with, the stationary fit of power transmission shaft front end is on radial ball bearing, and spacer ring is equipped with in the radial ball bearing below, between spacer ring and the tapered sleeve stage clip is housed, the mill bar of bistrique is contained in the power transmission shaft.
