Description

Miniature polishing machine

The utility model relates to a kind of miniature sanding machine, is meant the miniature sanding machine of a kind of motor vehicle repair especially.

Motor vehicle repair at present or spray paint need be removed old putty layer, smears new putty layer, polishing operation such as spray paint, and these operations need repeatedly repeat to polish the operation that polishes, and polish, and the polishing operation has directly determined the fineness of car surface.Existing sanding machine has electronic and pneumatic two kinds, its principle is to utilize to rotatablely move to be socialized in the garden by a vibrator that transhipment is moving to be converted to axial vibration, again sand paper is passed in vibration, make sand paper make axial up-down vibration and realize grinding purposes, because vibration frequency is very high, noise is big, the complete machine heaviness, use extremely inconvenience, hand is numb by vibration easily, and working environment is also influenced.

The purpose of this utility model provides a kind of rotation and rotates polishing, and in light weight, noise is low, vibrates little miniature sanding machine.

The purpose of this utility model be achieved in that according to feature of the present utility model it by power box 1, motor 2, joint 3, flexible axle 4, handle 5 and bistrique 6 formed; Wherein be equipped with knurled wheel 22 on motor shaft 21, be equipped with rubber tire 23 on the joint axis 31, knurled wheel 22 and rubber tire 23 interlock are mutually realized the power transmission of motor shaft 21 to joint axis 31; Joint axis 31 1 ends are fixed on bearing 25 top connection axles 31 other ends and are connected with flexible shaft end 33, and flexible shaft end central authorities are provided with groove 36, are used to insert the flexible axle core; Handle 5 comprises taper knob 53, bearing 54,56, and Handle axis 55, Handle axis 55 two ends are supported in respectively on the bearing 54,56, and Handle axis 55 1 ends have groove bolt 58, are used to insert the flexible axle core, realize the power transmission with joint 3; Handle axis 55 other ends are fixed on the adapter sleeve 61 of bistrique 6, and bistrique 6 is a square body, is fixed with nog plate 65 on adapter sleeve 61, and nog plate 65 skins are square washers 63, are covered with sand paper 66 outside the pad 63, and sand paper 66 blocks 64 fastening location by curved pressure.

Compared with prior art, advantage of the present utility model and good effect are significant, and its remarkable advantage is: 1. vibration is minimum, noise is very low, 2. in light weight, 3. rotary speed is moderate, and 4. efficiency and machining accuracy greatly improve, 5. alleviate labor strength, improve the working environment of workers, 6. cost is low, 7. not only can dry grind, the wet-milling of also can watering 8. can be applicable to the surfaces of various materials polishing.

Describe characteristics of the present utility model and enforcement in detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, the utility model be by power box 1, motor 2, and joint 3, flexible axle 4, handle 5, bistrique 6 parts such as grade are formed, and power box 1 includes shell 11, and shell 11 tops are provided with handle 13 and braces 14.Motor 2 and joint 3 are installed in the power box, be with knurled wheel 22 on the motor shaft 21, knurled wheel 22 and the rubber tire 23 that is enclosed within on the joint axis 31, constituted the motor speed reducing gear, motor 2 is fixed on the power box 1, joint 3 one ends are fixed on that the other end is fixed on the fixed head 12 on the shell 11, and motor 2 is by the power supply that links to each other with power supply of electric wire and plug 26.

Referring to Fig. 3, show the utility model plug profile, joint 3 outermost layers are with fitting sleeve 34, joint central authorities are joint axis 31, joint axis 31 links to each other with flexible shaft end 33 by bearing 32, flexible shaft end 33 central authorities have a groove 36 and are used to insert flexible axle axle core, and sliding sleeve 35 is used to connect the flexible axle leather sheath.

Referring to Fig. 4, Fig. 5 shows the cutaway view of the utility model handle 5 and bistrique 6 and the left view of bistrique 6 respectively, handle 5 is to construct like this, and the handle outermost layer is a taper knob 53, and the end that links to each other with flexible axle is a flexible pipe sleeve 51, be used to connect the flexible axle leather sheath, taper knob 53 two ends are equipped with bearing 54,56, bearing 54, be equipped with Handle axis 55 between 56, flexible pipe sleeve 51 central authorities are provided with a stationary sleeve 52, and the ledge of sleeve 52 central handle axles 55 has groove bolt 58, so that insert flexible axle axle core.Handle axis 55 other ends are fixedlyed connected with the adapter sleeve 61 of bistrique 6.
