Abstract
The utility model relates to a pneumatic polishing machine including a housing, a handle, an air flow adjusting valve, a main spindle, an end cap, a cylinder, a rotor, a blade, an auxiliary spindle and a rotary table. The inner cavity of the hand of the handle is provided with an air inlet tunnel communicated with an air pump and an air outlet tunnel communicated with a dust collecting bag. The end cap and the cylinder compose a turbine cavity whose inner part is provided with the main spindle by a bearing. The air inlet tunnel of the handle is communicated with the turbine cavity by the air flow adjusting valve. The rotor and the blade are arranged on the main spindle whose lower end is eccentrically provided with an auxiliary spindle, and the lower end of the auxiliary spindle is provided with a rotary table with a nylon knob web. The utility model has the advantages of uniform polishing and convenience of replacing the grinding sheet.
Description
The utility model relates to a kind of polissoir, particularly a kind of pneumatic sander.
Existing pneumatic sander mainly is made up of handle, fuselage, compressed-air power part, middle seat, rotating shaft and chassis.Chinese patent CN87210743U discloses " a kind of dust suction pneumatic sander ", and its technical scheme is to constitute vacuum chamber by fuselage, middle seat, chassis loam cake and chassis, has air admission hole and steam vent on the handle, the fixedly connected emery wheel in the lower end of main shaft.During work, in vacuum chamber, form a negative pressuren zone, after dust is inhaled into vacuum chamber, in steam vent was transported to dust bag, the pneumatic sander of this structure existed the emery wheel regular motion again, polished inhomogeneous, it is slow that main shaft drives the runner rotating speed, changes the shortcoming that emery wheel is time-consuming, require great effort.
The purpose of this utility model provides a kind of rotating speed height, and it is easy to change sand paper, polishes uniform pneumatic sander.
The purpose of this utility model is achieved in that this device comprises shell, handle, air volume regulating valve, main shaft, end cap, cylinder, rotor, blade, countershaft and rotating disk, inner chamber at handle is provided with an air intake passage that communicates with air pump and an air exhaust passage that communicates with dust bag, end cap and cylinder are formed turbine chamber, main shaft is installed in the turbine chamber by bearing, the air intake passage of handle communicates with turbine chamber by air volume regulating valve, main shaft is provided with rotor and blade, in the installation of the lower end of main shaft off-centre a countershaft, the lower end of countershaft has been installed one and has been had the rotating disk that nylon is taken net.
The utlity model has speed of mainshaft height, rotating disk drives abrasive disc around main shaft and countershaft compound motion, and polishing is evenly changed sand paper advantage easily.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the front view of pneumatic sander.
Fig. 2 is the upward view of Fig. 1.
Shown in Fig. 1-2, this device comprises handle 2, pneumatic control valve 6, shell 13, base 15, upper end cover 11, bottom end cover 17, blade 9, rotor 12, main shaft 21, countershaft 20 and rotating disk 22, inner chamber at handle 2 is provided with an air intake passage 1 and an air exhaust passage 24, the air intake and the air pump of air intake passage 1 join, and the gas outlet of air exhaust passage 25 communicates with dust bag; A spool 5 and support spring 4 are installed in the valve body of pneumatic control valve 6, and a control lever 3 is installed in the upper end of valve body 6, also has a pore 7 on valve body 6, and spring 4 is propped spool 5 at ordinary times, and control valve 6 is closed condition; Upper end cover 11, bottom end cover 17 constitute turbine chamber with cylinder 14, have an air intake and an exhaust outlet that communicates with control valve 6 on the upper end cover 11, main shaft 21 is installed on upper end cover 11 and the bottom end cover 17 by ball bearing 10 and 18, the top of main shaft 21 is with rotor 12, radially have four slideways along rotor 12, stud with blade 9 in the slideway respectively, blade 9 can slide along slideway, has a shallow slot on the side of blade 9.During work, air-flow blows blade 9 and promotes rotor 12, main shaft 21 rotations, and the lower end of main shaft 21 is connected with countershaft 20 off-centre, and the lower end of countershaft 20 is threaded with rotating disk 22, and the lower surface of rotating disk 22 is provided with nylon and takes net, is used to install sand paper 24.During use, the back side is had nylon takes the sand paper of net and is overlapped on the rotating disk 22, the air-flow that transports by air pump enters turbine chamber and forms negative pressuren zone 19 through inlet channel 1, air volume regulating valve 6, pore 7, in turbine chamber, form eddy current and promote 21 rotations of blade 9 drive main shafts, main shaft 21 drives countershaft, rotating disk 22, sand paper 24 rotations again, and sand paper 24 relative main shafts 21 are done the rotating random motion of double action.Because the suction function of turbine chamber is polished and dust enters air exhaust passage 25 by the hole of sand paper 24 and the hole of rotating disk 22, and enters dust bag.
Claims (5)
