BS6063牛头刨床的润滑系统是由八路分油器的环形槽分成七路输出来实现的,其中进入滑枕导轨副的油路中设有可调节流阀,其结构如图a。在图中,由于阀芯2的螺纹部分与圆柱面之间、螺套1的内外螺纹及分油器主体3中相应部位的螺纹与光孔之间均存在着同轴度误差,使得阀芯与孔之间无法正确配合,有的装不进,有的虽然装进去了,但因偏心造成间隙过大,无法调节开口大小,更无法关闭油路,造成滑枕导轨油液四溢. 改进后的结构如图b,它是将原节流阀阀芯一分为二,这样消除了以上所述的各种误差,便于装配,并能保证其配合间隙,密封性好。另外,在分油器主体右端面上开有直槽,使节流阀孔与环形槽接通,油液可按图中箭头所示方向流动,并对阀芯产生轴向
BS6063 shaper lubrication system is composed of eight road oil separator annular groove is divided into seven output to achieve, which entered the oil rail ram guide rail with adjustable valve, the structure shown in Figure a. In the figure, there is a concentricity error between the threaded portion of the valve body 2 and the cylindrical surface, the internal and external threads of the screw sleeve 1 and the threads and the light holes of corresponding parts in the oil separator body 3, so that the valve body And the hole can not be properly matched, and some do not enter into, and some though loaded into, but due to eccentric gap is too large, can not adjust the size of the opening, but also can not close the oil path, resulting in ram rail oil overflow. After the structure shown in Figure b, it is the original throttle valve spool is divided into two, thus eliminating the various errors described above, ease of assembly, and to ensure that with the gap, good sealing. In addition, there is a straight groove on the right end surface of the oil separator main body so that the throttle hole and the annular groove are connected, the oil can flow in the direction shown by the arrow in the figure, and the axial direction
