A longitudinal gear-rack transmission type honing fixture with rotatable drill pins comprises workpiece rotating and clamping assemblies and a fixture fixing assembly. The workpiece rotating and clamping assemblies are installed in the fixture fixing assembly. In each workpiece rotating and clamping assembly, a left clamping plate and a right clamping plate are spliced and fixed, semi-circular arc grooves are formed in the opposite faces of the left clamping plate and the right clamping plate, and every two semi-circular arc grooves are matched to form a bearing mounting groove for assembling an outer ring of a bearing. Inner rings of two bearings are fixed on each drill pin in an up-and-down manner, a driven gear is fixed in the middle of each drill pin, and the driven gears are meshed with racks. Longitudinal through grooves allowing the racks to penetrate are formed in the left clamping plates or the right clamping plates, a light bar with two ends being fixed is arranged in each longitudinal through groove, sliding holes of the racks sleeve the light bars slidably, the racks longitudinally stretch out of the stretching-out sections of the left clamping plates or the right clamping plates and are meshed with driving gears, and each driving gear is mounted on an output shaft of a driving motor. The drill pins of the honing fixture are rotatable, 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...
