The core of the utility model is to provide a polishing strip which can improve the yield of polishing special-shaped holes. Another core of the present invention is to provide a polishing rod assembly comprising the polishing strip described above, wherein the polishing strip improves the yield of polishing a shaped aperture.

Referring to fig. 2 and 3, a first embodiment of the polishing strip provided by the present invention includes a polishing main body 1, an outer surface of the polishing main body 1 includes a polishing side surface 11, and a tooth structure 12 and a tooth space structure 13 are alternately disposed on the polishing side surface 11 along a predetermined linear direction to form a sawtooth surface. In fig. 2, the predetermined linear direction extends in the vertical direction. The number of the tooth structures 12 and the number of the tooth space structures 13 can be set according to actual needs, and is usually at least two, and of course, each tooth structure can also be set one.

In the polishing process, the preset linear direction is correspondingly adjusted to the axial direction of the polishing hole, the polishing strip extends into the polishing hole, and the polishing driving device drives the polishing strip to rotate and axially move. Under the extrusion of the inner wall of the polishing hole, the polishing strip usually deforms to a certain extent, so that the polishing strip can be attached to the inner wall of the polishing hole for polishing. If the polishing hole is a special-shaped hole with a special-shaped part B with a radial size change, the straight body A can be polished by the tooth structure 12, the tooth socket structure 13 can polish the special-shaped part B, and the yield of polishing the special-shaped hole can be improved.

Further, as shown in fig. 2, the tooth structure 12 is a planar structure formed by arranging straight line segments parallel to the predetermined straight line direction along a direction perpendicular to the predetermined straight line direction, and it is possible to ensure that the tooth structure 12 has a large area for polishing the straight body position a of the polishing hole. In the embodiment, as shown in fig. 4, the straight line segments are arranged along a straight line direction to form a flat planar structure, specifically a rectangular plane; in other embodiments, as shown in fig. 6, the straight line segments may be arranged along a circular arc to form a cylindrical planar structure.

Further, as shown in fig. 2, on the polishing side surface 11, the planar structures are disposed on a plane parallel to the predetermined linear direction in a coplanar manner, so that the flexibility of the polishing strip can be improved, and any section of the tooth structure 12 of the polishing strip enters the polishing hole, thereby achieving the same polishing effect.

Further, as shown in fig. 2, the groove wall of the gullet structure 13 includes a groove slope 131 inclined with respect to a predetermined straight direction to accommodate polishing of the groove slope 131 in the shaped hole. Of course, in other embodiments, as shown in FIG. 5, the slot faces of the gullet structure 13 may all be formed parallel or perpendicular to the axial surface.

Further, as shown in fig. 2, the spline structure 13 is a V-shaped groove formed by abutting two groove slopes 131, and the two groove slopes 131 forming the spline structure 13 are sequentially arranged in a predetermined linear direction. That is, in the groove structure 13, along the predetermined straight line direction, the abutment point of the two groove slopes 131 is located between the free ends of the two groove slopes 131, and one of the groove slopes 131 is gradually closer to the middle of the polishing body 1 from the free end thereof toward the abutment point, and the other groove slope 131 is gradually farther from the middle of the polishing body 1 from the abutment point toward the free end thereof. Specifically, as shown in fig. 2, along the downward direction in the predetermined linear direction, in the groove structure 13, for the upper groove inclined plane 131, the free end thereof is upward, the butt point thereof is downward, the groove inclined plane 131 is gradually close to the vertical central line of the polishing main body 1 from top to bottom, for the lower groove inclined plane 131, the free end thereof is downward, the butt point thereof is downward, the groove inclined plane 131 is gradually far away from the vertical central line of the polishing main body 1 from top to bottom, so that the two groove inclined planes 131 can be used for polishing the groove inclined planes 131 with different inclination modes in the special-shaped hole, and the applicability is strong.

Further, as shown in fig. 2, the groove slope 131 is a flat surface, which facilitates machining. In addition, parameters such as the inclination angle and the length of the slot inclined plane 131 on the tooth socket structure 13 can be adaptively set according to the requirement of a polished hole to be processed. Of course, in other embodiments, the slot slope 131 may also be an arc-shaped surface.

Further, as shown in fig. 2 and 4, the polishing body 1 has a sheet-like structure, and the outer surface of the polishing body 1 includes two polishing side surfaces 11 disposed oppositely. Specifically, the length direction of the polishing side surface 11 is parallel to the predetermined straight line direction and has a large value, and the width direction thereof corresponds to the thickness direction of the polishing strip and has a small value, for example, 2 mm. Because the polishing holes may need to be added with polishing agents during polishing, the polishing strips are arranged into a sheet structure, and after the polishing strips are inserted into the polishing holes, sufficient space can be reserved in the polishing holes for placing the polishing agents. Of course, in other embodiments, the polishing strip may also be provided as a cylindrical structure, the axial direction of the cylindrical structure is a predetermined linear direction, and the tooth structures 12 and the tooth groove structures 13 are arranged on the circumferential surface of the cylindrical structure in a staggered manner along the axial direction of the cylindrical structure.

Further, as shown in fig. 2, the two polishing side surfaces 11 are symmetrically arranged, that is, the two polishing side surfaces 11 can coincide after rotating around an axis parallel to the preset linear direction, and then the two polishing side surfaces 11 can be simultaneously applied to polishing the inner hole during the polishing process, and the same effect is achieved by polishing. On the same polishing side surface 11, each tooth groove structure 13 is the same, and parameters including size, depth, distance between adjacent tooth groove structures 13 and the like guarantee standardization of each polishing strip and guarantee polishing effect on special-shaped holes. Of course, in embodiments thereof, one, three or another number of polishing side surfaces 11 may be provided.

When the polishing strip in this embodiment is used for polishing a special-shaped hole, the working principle is as shown in fig. 3, the polishing strip enters the polishing hole, the whole polishing length of the polishing hole is within the length range of the polishing strip, and the position, which is larger than the aperture of the polishing hole, on the polishing strip is extruded and deformed by the side wall of the polishing hole from the position of the dotted line in the initial state, so that the polishing strip can be attached to different positions of the polishing hole, and the polishing hole can be polished comprehensively by moving up and down and rotating the polishing strip.
