Abstract

A tiller key groove grooving device comprises a bottom plate and a tiller linear cutting correction disc, a boss matched with the small-diameter end of a tiller taper hole is arranged at the center of the upper end face of the bottom plate, a machining hole and a key groove machining groove are axially formed in the boss, the key groove machining groove is located on the outer side of the machining hole and communicates with the machining hole, and the correction disc is in a T shape and comprises a flange and a correction part which are coaxially arranged, the correction part is of a conical structure matched with the large-diameter end of the tiller taper hole in an inserted mode, and a correction hole is axially formed in the center of the correction disc. During usage, the correction disc is fixed to a workbench after being assembled on a tiller, then, the perpendicularity of the center line of the tiller taper hole and the workbench is corrected, a plurality of key grooves are roughly machined through linear cutting, then the bottom plate is fixed to the workbench, the tiller is assembled on the bottom plate, and finish machining is carried out after the perpendicularity of the bottom planes of the key grooves and the workbench is corrected. By means of the design, linear cutting machining of the tiller key grooves is achieved, machining cost is reduced, and machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tiller processing, and in particular relates to a tiller keyway slotting device and a use method thereof. Background technique [0002] With the improvement of ship technology at home and abroad and the needs of the ship industry, the requirements for the steering gear are getting higher and higher. The tiller is the main transmission part of the steering gear. Because most of it adopts traditional processing methods, the processing cost is relatively high. Today The price competition in the shipbuilding industry is fierce, so it is necessary to adopt reasonable processing methods. [0003] The middle hole of the tiller is designed in the form of a keyway on the taper hole, and the matching rudder shaft is also a tapered structure. It is required that the contact area between the tiller and the rudder shaft be more than 70% during assembly to increase the contact friction. At the same time, The keys also...
