在修理机床时,对于磨损的铜套,可以采用下列方法修复。(1)如图1,沿铜套轴向铣一条通槽a,要求槽a在全长的宽窄一致,光洁度▽▽5以上,槽口宽度为π·x再加上足够的内径加工余量。x为铜套与轴的间隙。(2)将铜套置于手压床上,从铜套中部的外径上向中心均匀加压,直至槽a密合。加压时,为了适当纠正铜套开槽后所形成的少量椭圆,A处用力应大些。(3)将铜套外径车去2～5毫米,至正圆后,再热压入钢套B,如图2,其配合为D/jd。钢套外径要留加工余量,待热压后再精车。由于铜套与钢套是热压
When repairing the machine tool, wear the copper sleeve, you can use the following methods to repair. (1) As shown in Figure 1, milling a through slot a along the axial direction of the copper sleeve, requiring groove a to have the same width and width over the whole length, finish ▽ ▽ 5 and notch width π · x plus sufficient inner diameter allowance . x is the clearance between copper sleeve and shaft. (2) The copper sleeve placed on the hand press, from the center of the outer diameter of the copper sleeve uniformly pressurized until the groove a close. Pressurized, in order to properly correct the copper sleeve after forming a small amount of oval, A force should be larger. (3) The copper outer diameter of the car to go 2 to 5 mm, to the perfect circle, and then hot press into the steel sleeve B, shown in Figure 2, with the D / jd. The outer diameter of the steel sleeve should leave the machining allowance, until after the hot pressing and fine car. As the copper sleeve and steel sleeve is hot
