The invention provides a chain wheel transmission type drill-pin-rotatable honing fixture. The chain wheel transmission type drill-pin-rotatable honing fixture comprises a workpiece rotating clamping assembly and a fixed fixture assembly, wherein the workpiece rotating clamping assembly is installed in the fixed fixture assembly. The workpiece rotating clamping assembly comprises a left clamping plate, a right clamping plate, first bearings and a big chain wheel. The left clamping plate and the right clamping plate are spliced and fixed, the opposite faces of the left clamping plate and the right clamping plate are provided with semi-circular-arc slots, the two semi-circular-arc slots are matched to form a bearing installation slot for assembling outer rings of the first bearings, and inner rings of the two first bearings are fixed to a drill pin vertically correspondingly. The middle of the drill pin is fixedly provided with the big chain wheel, and the big chain wheel is installed at one end of a transmission chain in a sleeved manner. The left clamping plate is provided with a work slot allowing the transmission chain to penetrate through, the other end, stretching out of the left clamping plate, of the transmission chain is sleeved with a small chain wheel, and the small chain wheel is installed on an output shaft of a drive motor. According to the chain wheel transmission type drill-pin-rotatable honing fixture, the drill pin is rotatable, honing is uniform, and the honing effect is good.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a rotatable honing fixture installed on a honing machine. 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 pre...
