A chain transmission type honing clamp with rotatable drill bit comprises workpiece rotating clamping assemblies and a fixed clamp assembly. The workpiece rotating clamping assemblies are installed inside the fixed clamp assembly. In each workpiece rotating clamping assembly, two clamping plates are spliced and fixed, semi-arc grooves are formed in the opposite surfaces of the clamping plates, andevery two semi-arc grooves are matched to form a bearing installing groove; a driven chain wheel is fixed to the middle of each drill bit, the upper end and the lower end of each driven chain wheel are each provided with an outward stretching sleeve, the outward stretching sleeves are connected with inner rings of bearings, and outer rings of the bearings are installed in the bearing installing grooves; the drill bits penetrate through via holes of the inner rings of the bearings; the driven chain wheels are installed on a transmission chain in a sleeving mode; longitudinal through grooves for allowing the transmission chain to penetrate are formed in the two clamping plates, one end of the transmission chain is arranged on a driving chain wheel in a sleeving mode, the driving chain wheelis installed on an output shaft of a driving motor, the other end of the transmission chain is installed on a fixed chain wheel in a sleeving mode, and the fixed chain wheel is installed on a chain wheel shaft. According to the chain transmission type honing clamp with the rotatable drill bit, the drill bits can rotate, 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 drill pin rotatable honing fixture installed on a honing machine. Background technique [0002] Extrusion honing technology is to squeeze a semi-solid fluid abrasive (composed of polymer carrier and abrasive) through the surface of the workpiece to be processed to achieve the effects of deburring, polishing, chamfering and changing the surface properties of the part in one processing. 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, cross channels, and special-shaped curved surfaces. Using 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...
