Automatic numerical-control polishing machine for inner wall of fluid pipeline elbow

Abstract

The invention discloses an automatic numerical-control polishing machine for the inner wall of a fluid pipeline elbow. The automatic numerical-control polishing machine comprises a machine base, a case and a polishing assembly, wherein the machine base comprises a support which is provided with a hopper adapting piece, and a drawing box is mounted in the hopper adapting piece; the case comprises a machine shell, bottom of which is provided with a dust collecting hopper communicating with the hopper adapting piece; the polishing assembly comprises a plane working surface and is provided with three dust suction ports and a dust suction head; a cam intermittent indexing box is mounted on the plane working surface, an input shaft of the cam intermittent indexing box is connected to a three-phase gear motor, an output shaft of the cam intermittent indexing box is connected to a rotating disc, four elbow clamps are distributed on the rotating disc, and corresponding polishing devices are arranged on the outer sides of the elbow clamps; and the polishing device comprises a cross-shaped adjusting table, a platform angle adjusting mechanism, an XYZ three-axis numerical-control platform and an elbow polishing mechanism. The transmission joint of the polishing arm is a key part of the automatic numerical-control polishing machine, so that the polishing head can extend into the inner cavity of the elbow to finish the polishing process at one time, and thus, the machining efficiency is high, intelligent control is achieved, and operation is easy.

Description

Technical field[0001]The present invention relates to a polishing machine, and more particularly to a fluid conduit interior wall automatic CNC polishing machine.Background technique[0002]At present, the internal walls of the domestic fluid pipeline are polished. It is basically artificial, low production efficiency, high cost, dust pollution, and directly seriously affecting the health of employees. Existing extrusion throws, electrolysis, vibration, sandblasting throwing equipment are not targeted, unable to solve existing shortcomings, such as ribbon wire traces cannot achieve polishing effect, elbow head tail tail tail tail tail tail Slip port, polishing light surface or brushed effect is uneven, the polishing color difference is large, the wall thickness is uneven, the speed is slow, the quality is high, the production cost is high, and the environment is difficult. At the same time, existing mechanical polishing machines are all polished by direct arm polishing or linear polis...

Problems solved by technology

[0002] At present, the polishing of the inner wall of domestic fluid pipeline elbows is basically done manually, which has low production efficiency, high cost, and large dust pollution, which directly and seriously affects the health of employees.

The existing extrusion polishing, electrolytic polishing, vibration polishing, sandblasting polishing and other equipment are not targeted at the product to be determined, and cannot solve many existing shortcomings, such as the silk road traces of the rough product cannot achieve the polishing effect, and the contour of the head and tail diameter of the elbow is polished. Slip surface, uneven polished surface or drawing effect, large color difference in polishing, uneven wall thickness, slow speed, low quality, high p
