The invention relates to an ultrasonic honing head applicable to the machining of an excircle of a long and thin rod. The ultrasonic honing head mainly consists of a substrate, a supporting frame, an oil stone frame, an oil stone, a centralizing block supporting frame and a centralizing block, wherein the supporting frame is connected with a supporting seat through a bolt, the supporting seat is matched with a T-shaped groove in the substrate through a T-shaped convex platform to enable the substrate to move along the axial direction, the oil stone frame and the centralizing block supporting frame are installed on the substrate and distributed along the circumferential direction of the substrate, the oil stone is installed on the oil stone frame, the centralizing block is installed on the centralizing block supporting frame, a guide plate controls the movement directions of the oil stone frame and the centralizing block through a guide groove, and a feeding oil cylinder is connected to the substrate and pushes the substrate to do axial movement so as to realize the radial feeding of the oil stone and the centralizing block. The ultrasonic honing head is applicable to the hone machining of the excircle of a long and thin rod part, and can be used for effectively improving the hone machining efficiency and machining precision, reducing the surface roughness of a workpiece, prolonging the service life of the oil stone and improving a cooling effect of cooling fluid.
Description
technical field [0001] The invention relates to an ultrasonic honing head suitable for machining the outer circle of a slender rod, belonging to the technical field of honing. Background technique [0002] Slender rod parts are widely used in construction machinery, and workpieces such as piston rods used in construction machinery telescopic arms are all slender rod parts. Due to the large length-to-diameter ratio and poor rigidity, such parts are prone to vibration and bending deformation under the action of cutting force and self-gravity, which seriously affects the machining accuracy and surface roughness of the parts. Therefore, there is an urgent need for a high-precision machining method suitable for the outer circle of the slender rod. [0003] For the precision machining of the outer circle of high-precision slender rod parts, the cylindrical honing process is generally used at present, but the traditional cylindrical honing has many problems in the actual process o...
