Abstract
A line cutter upper/lower idler pulley bearing gas pressure sealing device includes a bearing sleeve 13, a bearing 15, a bearing pressing cover 12, an idler pulley 14, an air inlet pipe 16, a pipe joint 17 and a compressed air generator. The bearing 15 is arranged in the bearing sleeve 13 and is tightly pressed by the bearing pressing cover 12. The idler pulley 14 is arranged between left and right groups of bearings. The bearing pressing cover 12 is provided with a through hole which is provided with the pipe joint 17; one end of the air inlet pipe 16 is connected with the pipe joint 17; the other end of the air inlet pipe 16 is connected with an air supply nozzle 22 of the compressed air generator. An air pump 18, a pressure gauge 19, a water separator 20, an air valve 21 and the air supply nozzle 22 of the compressed air generator are sequentially connected. The air supply nozzle 22 is connected with the pipe joint 17 of each bearing pressing cover 12 by the air inlet pipe 16. The utility model avoids the metal powder in the cutting liquid entering the bearing to abrade the bearing on the function of the compressed air, and prolongs the service life of the bearing by 4-5 times.
Description
Technical field
The utility model relates to electromachining equipment, and especially a kind of good seal performance can prolong that lower guide wheel shaft holds pressurized seal device on the bearing wire cutting machine in service life.
Background technology
Current, produce both at home and abroad and the wire cutting machine that uses and go up lower guide wheel shaft and hold as shown in Figure 1 and Figure 2.Wire cutting machine mainly is made of lathe bed 11, column 4, upper support arm 5, lower support arm 9, winding drum 1, back guide wheel 3, upper block assembly 6, lower tumbler assembly 10 and molybdenum filament 2.Upper block assembly 6, lower tumbler assembly 10 are contained in the front end of upper support arm 5, lower support arm 9 respectively, and back guide wheel 3, winding drum 1 are contained in the rear portion of upper support arm 5 and column 4.Molybdenum filament 2 is wrapped on the winding drum 1, and 14 motions of the guide wheel in back guide wheel 3, upper block assembly 6 and lower tumbler assembly 10, utilizes the electric machining principle that metal is cut.Nozzle of cutting fluid 7,8 is equipped with at upper block assembly 6, lower tumbler assembly 10 places respectively, in order to the processing district is cooled off and deslagging.The cooling and deslagging in, also the part metals powder has been brought in the bearing 15 of upper block assembly 6 and lower tumbler assembly 10, cause bearing very quick-wearing scrap.
Summary of the invention
The purpose of this utility model is at present wire cutting machine the processing district to be carried out in the cooling procedure, metal dust easily enters in the bearing of upper block assembly and lower tumbler assembly, cause the very quick-wearing problem of scrapping of bearing, provide a kind of cutting fluid that prevents to bring metal dust into bearing, lower guide wheel shaft holds pressurized seal device on the bearing wire cutting machine in service life thereby prolong.
Lower guide wheel shaft holds pressurized seal device on the wire cutting machine described in the utility model, comprises bearing holder (housing, cover), bearing, bearing gland, guide wheel, air inlet pipe, pipe joint and compressed air generator.Bearing is loaded in the bearing holder (housing, cover), compresses with bearing gland.About guide wheel is loaded between two groups of bearings.Bearing gland is provided with through hole.Pipe joint is housed in the through hole, and an end of air inlet pipe is communicated with bearing gland inner bearing chamber by pipe joint.The air feed mouth of the other end of air inlet pipe and compressed air generator joins.
Compressed air generator comprises air pump, Pressure gauge, separator, air valve and air feed mouth.Air pump, Pressure gauge, separator, air valve and air feed mouth are connected successively.The air feed mouth is connected with pipe joint on each bearing gland by air inlet pipe.
During work, the compressed air that compressed air generator produces feeds in the left and right sides bearing chamber of going up the lower tumbler assembly, under compressed-air actuated effect, has certain air pressure in the bearing chamber, make cutting fluid can not flow into bearing chamber, avoided the metal dust in the cutting fluid that bearing is caused wearing and tearing.
Enforcement of the present utility model can make prolong 4-5 doubly the service life of bearing.
