The invention is realized by the following steps: the frock includes outer ring, interior ring, removes the slider, the slider pillar is constituteed with the dish lid, and interior ring sets up in outer ring the inside, and the slider pillar passes through screw thread rotation and installs on removing the slider, and the rectangular downthehole of ring including removing the slider setting, the slider pillar passes through on the circular port in the interior ring outside leads to the sawtooth of outer ring, and the dish lid passes through the screw fixation on outer ring, and the processing work piece is the long strip downthehole of ring including the small crystal bar setting.

The invention also has the technical characteristics that:

(1) the outer diameter and the inner diameter of the outer ring are respectively 370mm and 303mm, and the thickness is 16-18mm

(2) The outer side of the whole inner ring is uniformly provided with arc-shaped sawteeth, the depth of the sawteeth is 12-15mm, and the maximum degree of the circular arc of the sawteeth is 17-19 mm.

(3) The inner ring is arranged in the outer ring, the outer diameter and the inner diameter are respectively 300mm and 120mm, and the thickness is 38-42 mm. 8-12 strip holes are uniformly distributed on the inner ring, and the outer side surface of the inner ring is provided with a circular hole communicated with the strip holes;

(4) the slider pillar passes through the circular port and links to each other with inside removal slider, and the slider pillar meets the department with outer ring sawtooth, through rotating interior ring, drives slider pillar and inside removal slider, fixes the downthehole little crystal bar of rectangular.

(5) The side surface of the outer ring is provided with a screw hole for fixing the position of the slide block strut and ensuring that the small crystal bar of the processing workpiece is confined in the tool. And a disk cover screw hole is formed in the upper surface of the outer ring, and the disk cover is fixed through screws.

(6) The whole tool is cylindrical, the joint of the tool and the movable sliding block is a plane, and the joint of the tool and the sawtooth of the outer circular ring is spherical. The length of the support is 13-15 mm.

(7) The outer diameter of the disk cover is 370mm, the inner diameter is 270mm, and the thickness is 4-6 mm.

And (4) putting the tool on a polishing machine, starting a polishing solution circulating device, and starting equipment for polishing.

The invention has the following beneficial effects:

(1) the tool can be used for placing a plurality of workpieces at one time, is convenient to assemble and disassemble, and can greatly improve the machining efficiency.

(2) The invention is provided with the saw teeth, the sliding block and the sliding block support which are matched, and can process various specifications and sizes, and the diameter size range of the crystal bar is within 20mm-30 mm.

(3) The inner ring material needs surface treatment, has small surface roughness, prevents the polishing solution from being corroded, and ensures that the surface of the crystal bar is not scratched for the second time.

(4) The invention has simple structure and easy operation, and the surface quality of the processed piece can meet the requirement.

The invention can be used for a long time, replaces the consumption of the original auxiliary materials and reduces the cost.

Detailed Description

The invention is described in detail below with reference to the accompanying drawings:

referring to fig. 1-3, the present embodiment is mainly composed of an outer ring 1, an inner ring 2, a movable slider 3, a slider support 4, and a disk cover 5. Interior ring 2 sets up in 1 the inside of outer ring, and slider pillar 4 passes through the screw thread rotation to be installed on removing slider 3, and the rectangular downthehole of ring 2 including removing slider 3 setting, slider pillar 4 leads to on the sawtooth of outer ring 1 through the circular port in the 2 outsides of inner ring, and the dish lid 5 passes through the screw fixation on outer ring 1.
