Embodiment Construction

[0029] In describing the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", The orientation or positional relationship indicated by "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than Nothing indicating or implying that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation should therefore not be construed as limiting the invention.

[0030] Such as image 3 As shown, the present embodiment provides a kind of tool for processing the tapered pin hole with the tiller below the rudder bearing and the rudder stock, including a tapered pin hole processing tool body 5, a boring bar 3 and a transition sleeve 4, one end of the...

Abstract

The invention discloses a method for machining matching tapered pin holes of a tiller and a rudderstock below a rudder bearing and a machining cutter. The machining cutter comprises a step reamer, a step rough rimer, a semi-finishing rimer, a finishing rimer, a boring bar and a transmission sleeve. One ends of the step reamer, the step rough rimer, the semi-finishing rimer and the finishing rimerare all provided with connection portions fixed to one end of the transmission sleeve. The other end of the transmission sleeve is fixed to the boring rod. According to the method for machining the matching tapered pin holes of the tiller and the rudderstock below the rudder bearing and the machining cutter, by means of arranging the transition sleeve, the technical problem that when an upper rudder bearing is arranged above a connection portion of the tiller and the rudderstock and the tiller and the rudderstock are connected through tapered pins, the tapered pin holes cannot be machined is solved, and under the condition that the space of a stern of a ship is limited, the means of moving the upper rudder bearing to above the connection position of the tiller and the rudderstock becomes practicable.

Description

technical field [0001] The invention belongs to the technical field of rudder system processing in shipbuilding, and in particular relates to a processing method and a processing tool for matching a tapered pin hole with a tiller below a rudder bearing and a rudder stock. Background technique [0002] In the design of ship rudder system, when the rudder stock and the tiller are connected by conical pins, the conventional design is to bear the weight of the rudder system (rudder blade, rudder stock and other underwater parts) or the one-way thrust bearing, which is set on the tiller Below the connection part with the rudder stock, the top surface of the rudder stock is set to be flush with the upper plane of the rudder handle, and the connecting taper pin holes on the rudder stock and the rudder handle are to be reamed at the same time. The inner surface roughness of the taper pin hole is required to be 0.8. Good taper pin hole single matching processing, this connection form...
