CR 61125 A重型车床的光杠近十米长,由三节组成并带有键槽。由于事故造成光杠弯曲达1毫米,为此,我们对它进行了矫直。一、矫直前的准备工作加工七件等高的V形铁;根据光杠直径ф70_(-0.18)~(-0.12)毫米,加工八件ф70_(-0.28)~(-0.22)毫米的套,并把一件4等分切开,其中1/4的R套块作为受力点和光杠接触,保证光杠的表面在受压时不受伤(图1);铜棒一件;百分表连表架一套。将毫米套装在光杠外圆上(六件),承放在V型铁中,带有键槽的光杠就可以在套内转360°,以检验径向跳动值。
The light beam of the CR 61125 A heavy duty lathe is nearly ten meters long and consists of three sections with keyways. The light bar flexed by 1 millimeter as a result of the accident and for this reason we straightened it. First, the preparation before straightening Seven high-profile V-shaped iron processing; according to the light bar diameter ф70 _ (- 0.18) ~ (-0.12) mm, machining eight ф70 _ (-0.28) ~ (-0.22) And cut a 4 points, of which 1/4 of the R block as the force point and light bar contact, to ensure that the surface of the light bar is not injured when the pressure (Figure 1); a copper rod; dial indicator Even a table frame. Assemble the millimeter on the outer circumference of the light bar (six pieces) and place it in a V-shaped iron. The light bar with keyway can be rotated 360 ° inside the case to check the radial runout.
