Rudder blade taper hole boring device

Abstract

The invention discloses a rudder blade taper hole boring device, and relates to the field of rudder blade taper hole machining devices. The rudder blade taper hole boring device comprises a boring rodbody, wherein the lower surface of the boring rod body is a horizontal plane; the upper surface is a slope structure; transmission shafts are fixed to the two ends of the boring rod body respectivelyand installed on a supporting frame through bearing pedestals; the transmission shaft on the right side of the boring rod body is connected with a first driving device; the transmission shaft on theleft side of the boring rod body is connected with an adjusting block; bolts penetrate through waist-shaped holes in the side face of the boring rod body and mounting holes in the side face of a trackto fix the track onto the boring rod body; a tool rest is arranged on the track; a turning tool is installed on the tool rest; a lead screw is arranged at the lower end of the tool rest; and the right end of the lead screw is connected with a second driving device. According to the rudder blade taper hole boring device provided by the invention, automatic intermittent fit of axial movement and radial rotation of the tool rest is achieved, so that the working efficiency is high; and by combining with the slope structure of the boring rod body, the angle of a taper hole is adjusted, so that large-range adjustment of the diameter of the taper hole is achieved, the problem of coaxial alignment of the transmission shafts and the taper hole is solved, the precision is high, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of rudder blade cone hole processing devices, in particular to a rudder blade cone hole boring device. Background technique [0002] With the increasing demand for domestic ships, the area of ​​the rudder blade increases with the increase of the tonnage of the ship, resulting in an increase in the diameter of the rudder stock. [0003] In the past, the machining of taper holes of ship rudder blades was done by CNC machine tools, with narrow application range and limited processing environment. The size and weight of workpieces to be processed were limited by the type of processing equipment, and there were many preparations before processing. For machining parts with strict requirements on tapered holes and coaxiality, traditional boring equipment is difficult to process, and manual processing is mostly used. For this reason, the processing process takes a long time and the cost of machine tool processing is high. C...

[0003] In the past, the processing of taper holes of ship rudder blades was completed by CNC machine tools, with narrow application range and limited processing environment. The size and weight of workpieces to be processed were limited by the type of processing equipment, and there were many preparations before processing.

For machining parts with strict requirements on tapered holes and coaxiality, traditional boring equipment is difficult to process, and manual processing is mostly used. Therefore, the processing process takes a long time and the cost of machine tool processing is relatively high.
