Problems solved by technology

[0003] At present, most of the honing fixtures use a single clamping structure. The drill pin is always in a fixed position during the whole honing process. If the abrasive flow interface around the drill pin is inconsistent, the speed of the abrasive passing through will be different, resulting in uneven honing of the drill pin. As a result, the final honing effect is relatively poor, so a new fixture structure is urgently needed to improve this honing defect

Abstract

The invention discloses a rotary honing fixture mechanism. The fixture mechanism comprises a workpiece rotary clamping module and a fixed fixture module; the workpiece rotary clamping module is mounted in the fixed fixture module; the workpiece rotary clamping module comprises fastening pieces and bearings; two fastening pieces are fixedly assembled; semiarc grooves are formed in opposite surfaces of the two fastening pieces; two semiarc grooves are matched to form a bearing mounting groove for assembling outer rings of the bearings; and inner rings of the two bearings are fixed on a drill point up and down. The rotary honing fixture mechanism improves the mechanical performance of the drill point, and improves the honing efficiency.

Description

technical field [0001] The invention belongs to the field of honing fixtures, in particular to a rotary honing fixture mechanism. Background technique [0002] Extrusion honing technology is to achieve deburring, polishing, chamfering and changing the surface properties of parts in one process by extruding semi-solid fluid abrasives (composed of polymer carriers and abrasives) through the surface of the workpiece to be processed. It can process multiple surfaces of multiple workpieces at the same time, and can efficiently and economically process surfaces with complex geometric shapes such as narrow slits, intersecting channels, and special-shaped surfaces. The use of extrusion honing instead of manual polishing can greatly reduce labor intensity, improve productivity, and ensure the consistency of product processing. At the same time, extrusion honing has high efficiency, good quality, simple equipment and convenient operation. [0003] At present, honing fixtures mostly ...
