Radius Rod Spherical Surface Profiling Device

Abstract

The invention discloses a radius rod spherical surface contour machining device. The radius rod spherical surface contour machining device comprises a sliding base, a sliding rod knife rest, a linkage rod, a radius rod and a rotary handle, and is characterized in that the sliding base is fixed on a large layer board of a large tool body and provided with the sliding rod knife rest; a cutting knife is arranged at one end of the sliding rod knife rest; the other end of the sliding rod knife rest is rigidly connected with the linkage rod; the other end of the linkage rod is hinged to one end of the radius rod; the effective length of the radius rod is equal to the radius of a workpiece spherical surface; the other end of the radius rod is rigidly connected to the rotary handle; the rotary handle is hinged to a small layer board of a small tool body. The radius rod spherical surface contour machining device is easy to machine, low in expense, high in universality, and capable of conveniently clamping parts, parts machined through the device are high in precision and low in cost, and the radius rod spherical surface contour machining device is an ideal contour machining device of large spherical surface parts.

Description

technical field [0001] The invention belongs to the field of machine tool accessories, and relates to a profiling processing device for turning a large spherical surface, in particular to a profiling processing device for a radius rod spherical surface. Background technique [0002] When turning extra-large parts, a main machine is generally used as a lathe, and an auxiliary machine is a worm gear drive mechanism to jointly complete the processing task. The lathe mainly completes the tool clamping and feeding, and the worm gear drive mechanism mainly completes the workpiece clamping and rotation drive. . Generally, extra-large spherical parts have a diameter of several meters or even more than 10 meters. At present, the turning of such parts mostly uses profiling for profiling. Formwork clamping is also more difficult. In addition, the amount of such parts is very small, and the spherical processing profiles of different diameters cannot be used universally, and sometimes ...

AI Technical Summary

Problems solved by technology

Generally, extra-large spherical parts have a diameter of several meters or even more than 10 meters. At present, the turning of such parts mostly uses profiling for profiling. Clamping by profiling is also more difficult

In addition, the amount of such parts is very small, and the spherical processing profiles of different diameters cannot be used universally, and sometimes the profile of a part may lose its use value after processing

Therefore, the profiling of super large spherical parts by profiling will lead to a sharp increase in the cost of parts
