Abstract
The utility model relates to a floating centrifugal deep hole polishing device. The device can be used for polishing a large-volume and asymmetrical workpiece to a high precision, and polishing abrasive paper of the device can be quickly replaced without detaching the whole device. The device is characterized in that the rear lateral surface of a front floating block is in a two-step shape of which the circumference is low and the circle center is high in the radial direction of a cylinder; the bottom of a rear floating block close to the circle center part of the cylinder is tightly attached to the step surface on the rear side of the front floating block; the front lateral surface of the rear floating block, the step surface on the rear side of the front floating block and the rear lateral surface close to the circumference part of the cylinder form an abrasive paper groove; and a screw penetrates through the rear floating block and the abrasive paper positioned in the abrasive paper groove and is fixed on the front floating block.
Description
Technical field
The utility model relates to a kind of centrifugal deep hole burnishing device that floats, the special endoporus that adapts in the large-scale asymmetric machined part of polishing.
Background technology
The deep hole of existing mechanical processing parts generally carries out on boring machine, and the deep hole roughness after the boring machine right boring generally is up to Ra3.2.When high again, just can only arrive on the internal grinder and process, but can not process the deep hole of the big and asymmetric part of volume on the internal grinder to the requirement on machining accuracy of deep hole.
Summary of the invention
The purpose of the utility model be to provide a kind of can be with volume big and deep hole roughness asymmetric part again be worked into more than the Ra3.2, and can change the burnishing device of polishing medium fast.
The related endoporus burnishing device of the technical scheme of the utility model comprises axle, cylindrical shell, axle sleeve, rocker piece, sand paper, cover plate and nut; Axle be a left side high right low three sections stepped, the axle middle part is passed cylindrical shell and cover plate successively, is with nut on the screw thread that the axle right part has; Cylindrical shell be a left side high right low two sections stepped, on the outer circumference surface of cylindrical shell right part axle sleeve is installed, and radially has gap slot; Preceding rocker piece is opposite in the said gap slot with rocker piece tangential, back mutually; With the gap slot matched in clearance; Preceding rocker piece radially is low near the cylindrical shell circumferential part respectively with rocker piece left and right side, back, center of circle portion is high two sections are stepped, and the right side of axle sleeve and the left side of cover plate are positioned at the left surface and the right flank of cylindrical shell circumferential part respectively near preceding rocker piece and back rocker piece; Before rocker piece trailing flank along cylindrical shell radially be two sections that the circumference place is low, circle centre position is high stepped; Back rocker piece is close to the cascaded surface of preceding rocker piece rear side near the bottom surface of cylindrical shell center of circle portion; The cascaded surface of the leading flank of back rocker piece, preceding rocker piece rear side and form the sand paper groove near the trailing flank of cylindrical shell circumferential part, screw passes the back rocker piece and is fixed on the preceding rocker piece with the sand paper that is positioned at the sand paper groove.
This deep hole burnishing device is along with in the boring spindle rotary course, and rocker piece can radially outwards move owing to action of centrifugal force, and the sand paper in the sand paper groove just can push the also inner hole wall of grinding part, thereby reaches the purpose of polishing endoporus.Since the rocker piece left and right side, left and right side of rocker piece along cylindrical shell radial circumference place high two sections of low circle centre position stepped; Axle sleeve and cover plate are pressed in the left and right side of rocker piece near the cylindrical shell circumferential part respectively; In this device use; Because axle sleeve and cover plate can support the cascaded surface of rocker piece left and right sides respectively, make rocker piece can in gap slot, not drop out.This scheme be applicable to the bigger situation of boring ratio that will polish; Not only screw is more near the sand paper groove; Can be with more firm being fixed in the sand paper groove of sand paper, and when changing sand paper, the nut on the axle that do not need to dismantle earlier; Dismantling tightens up the screw of sand paper again, just passable as long as direct dismounting tightens up the screw of sand paper.

The specific embodiment
As shown in Figure 1, the unsteady centrifugal deep hole burnishing device that the utility model relates to comprises axle 1, cylindrical shell 2, axle sleeve 3, rocker piece 4, sand paper 5, cover plate 6 and nut 8.As shown in Figure 5, axle 1 be a left side high right low three sections stepped, the left part of axle 1 is cone shape substantially, matches with the spindle hole of boring machine; The right part of axle 1 is cylindrical shape, passes cylindrical shell 2 and cover plate 6 successively, the endoporus and the axle 1 middle part outer circumference surface matched in clearance of cylindrical shell 2 and cover plate 6; The right part of axle 1 has screw thread 12, and screw thread 12 is with nut 7, and nut 7 is locked at cylindrical shell 2 between first cascaded surface 13 and cover plate 6 of axle 1.Like Fig. 4 and shown in Figure 5, cylindrical shell 2 be a left side high right low two sections stepped, the right part of cylindrical shell 2 radially has 4 gap slots 11, these four gap slots 11 are along the circumferencial direction equidistant placement of cylindrical shell 2.Like Fig. 1, shown in 2 and 3, rocker piece 41 and back rocker piece 42 before rocker piece 4 is divided into, the tangential is opposite in the gap slot 11 mutually, with gap slot 11 matched in clearance, can be free to slide along gap slot 11.Before rocker piece 41 and back rocker piece 42 left surfaces and right flank radially to be low two sections in the high circumference of circle centre position place along cylindrical shell 2 stepped; The outer circumference surface matched in clearance of the endoporus of axle sleeve 3 and cylindrical shell 2 right parts; The left side of axle sleeve 3 is close to the cascaded surface of cylindrical shell 2, and the right side is near preceding rocker piece 41 and the left surface of back rocker piece 42 near the cylindrical shell circumferential part.Cover plate 6 is "] of hollow " type, rocker piece 41 and the right flank of back rocker piece 42 near the cylindrical shell circumferential part, the left side of portion of remaining silent before openend is pressed near nut 7.Before rocker piece 41 trailing flank along cylindrical shell 2 radially be two sections that the circumference place is low, circle centre position is high stepped; Back rocker piece 42 is close to the cascaded surface of preceding rocker piece 41 rear sides near the bottom surface of cylindrical shell center of circle portion; The cascaded surface of the leading flank of back rocker piece 42, preceding rocker piece 41 rear sides and form sand paper groove 9 near the trailing flank of cylindrical shell 2 circumferential parts, screw 10 passes back rocker piece 42 and is fixed on the preceding rocker piece 41 with the sand paper 5 that is positioned at sand paper groove 9.
