A belt wheel drive type drill point rotatable honing clamp comprises a workpiece rotary clamping assembly and a fixed clamp assembly. The workpiece rotary clamping assembly is mounted in the fixed clamp assembly. The workpiece rotary clamping assembly comprises a left clamping plate, a right clamping plate, a first bearing and a big belt 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-circle grooves. The two semi-circle grooves are matched to form bearing mounting grooves allowing outer rings of first bearings to be assembled. Inner rings of the two first bearings are fixed to a drill point up and down. The big belt wheel is fixed to the middle of the drill point. One end of a transmission belt is sleeved with the big belt wheel. The left clamping plate is provided with an operation groove allowing the transmission belt to penetrate through. The other end, extending out of the left clamping plate, of the transmission belt is sleeved with a small belt wheel, so that the small belt wheel is mounted on an output shaft of a driving motor. The drill pin can rotate, honing is even, 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...
