Abstract

The invention relates to a floating reamer handle applied to the finish machining of a small-column inner hole and an assembling method of the floating reamer handle. The floating reamer handle comprises an outer sleeve, wherein a step hole is formed in side end of the outer sleeve, a movable joint rod which penetrates out one side end of the outer sleeve and is provided with Morse taper is arranged in the outer sleeve, a movable joint connecting sleeve which penetrates out the other side end of the outer sleeve is further arranged in the outer sleeve, the movable joint connecting sleeve is limited in the outer sleeve through a tightness adjusting mechanism, an adjusting mechanism for finely adjusting the cut depth is arranged at the end part, located in the outer sleeve, of the movable joint connecting sleeve, and a shaft rod for mounting a milling cutter is mounted at the other end of the movable joint connecting sleeve through a connecting mechanism. The floating reamer handle simple and skillful in structure and convenient to manufacture, a 'horn mouth' phenomenon occurring at a hole is effectively avoided, and meanwhile, the assembling method is simple and convenient.

Description

technical field [0001] The invention relates to a floating reamer shank used in finishing the inner hole of a small cylinder and an assembly method thereof. Background technique [0002] For workpieces with relatively deep cylindrical holes, general enterprises leave a finishing allowance of 0.05 to 0.2 mm after turning with a single-edged turning tool, and then use a sample knife or floating boring tool for finishing. For cylindrical holes with smaller diameters, a reamer is used for finishing machining, and when a reamer is used for fine reaming on a lathe, a "bell mouth" phenomenon often appears at the hole. For this, a floating reamer handle is required. Contents of the invention [0003] The object of the present invention is to provide a floating reamer handle and its assembly method for the finishing of small cylindrical inner holes. The floating reamer handle has a simple and ingenious structure, is convenient to manufacture, and effectively avoids the phenomenon ...
