The invention discloses a polishing device for the inner wall of a metal pipe, including a honing body and a plurality of padding blocks. A plurality of transition holes are opened on both sides of the honing body. One side of the cushion is fixed with a regulating pin, a fixed seat is installed on the other side of the pad, a groove is opened on the fixed seat, and a blind hole is set on both sides of the concave groove, and oil is respectively set on the side wall of the concave groove. The main body of the horizontal part of the stone is placed in the groove and the two ends of the horizontal part are placed in the blind hole, and a rubber strip is arranged between the blind hole and the oil stone level; the interior sliding of the honing body is arranged with a adjusting rod, and the movable end of the adjusting pin is provided with a slope with a protuberance, and a smooth circular face and a conical surface are set on the protuberance, and flat on the flat. The circular surface and the conical surface are connected with a transitional circular surface. In order to prevent the relative displacement between the fixed seat and the stone, the invention can prevent the relative displacement between the fixed pedestal and the oil stone through the deformation or recovery of the rubber strip during the operation to prevent the relative displacement between the fixed seat and the stone, so as to ensure the synchronism of the operation and prevent the damage of the oil and stone.

技术介绍
珩磨加工是一种具有广泛前途的切削技术,它不仅是一种能够提高表面粗糙度的加工方法,而且成为能够快速可靠地去除一定得余量、提高工件内表面精度的一种半精加工和精加工的工艺方法。珩磨不需要特殊的条件就能使零件获得精确的尺寸、几何精度、军工和工程机械等制造业中。珩磨加工属于精整加工,可以获得比一般机械加工更高的加工精度,其特点是使用高品质微粒磨料制成的固结磨具油石,微粒能够保证高水平的加工精度,要求磨料粒度、模具硬度和组织保持良好的一致性,要求模具尺寸形状保持较高的准确性,并且为了实现各切削刃做微小的切削和高效的切削,要求磨具和工件有较大的接触面积,因此精整加工要求有良好的降温、冷却和排屑条件。但是现有的立式珩磨机中,珩磨头在工件内表面的粗糙度降低至最小水平时,珩磨头上的油石与工件内壁之间的接触面积减小,使得珩磨头上的多个油石出现空转现象,在调节与工件内壁之间的间距之前,油石在高速运转过程中骤然失去工件内表面上突起物的阻碍力度,进而使得油石的转速骤然提高,使得油石与珩磨头本体之间的同步 ...
