Polishing machining process for iron casting

Abstract

The invention relates to the technical field of iron casting machining, in particular to a polishing machining process for an iron casting. A machining base, a sealed upper box body, a control unit, a workbench, a mechanical arm, an iron scrap collecting mechanism, a polishing mechanism and a workpiece fixing clamp are included in the polishing machining process. The workbench is installed at the position, close to the upper end face of the machining base, of the inner wall of the machining base, a workpiece fixing clamp used for containing a blank and a mechanical arm used for driving the polishing mechanism to walk are symmetrically installed on the upper end face of the workbench through bolts, an iron scrap collecting mechanism is connected to one side of the polishing mechanism, and the sealed upper box body is placed at the top of the machining base; and two observation windows are symmetrically installed on one side of the sealed upper box body through hinges, a control unit is installed on the outer wall of one side of the machining base, and the control unit is electrically connected with the mechanical arm. According to the polishing device, the scrap iron collecting procedure in the polishing process is effectively improved through the mode of combining wind suction and magnetic attraction, and polishing motors with different rotating speeds can be arranged for use.

Description

technical field [0001] The invention relates to the technical field of processing iron castings, in particular to a grinding process for iron castings. Background technique [0002] Iron castings refer to items cast from molten iron. The quality of cast iron has a great influence on the performance of mechanical products. For example, the wear resistance and dimensional stability of machine tool castings directly affect the precision and maintenance life of the machine tool; the size, accuracy and surface roughness of the impeller, housing and hydraulic parts of various pumps directly affect the pump and the working efficiency of the hydraulic system, energy consumption and cavitation development, etc.; the strength and resistance to shock and heat of internal combustion engine cylinder blocks, cylinder heads, cylinder liners, piston rings, exhaust pipes and other copper castings directly affect the work of the engine life. [0003] Among them, in the dimensional stabilit...

Problems solved by technology

At present, grinding robots are generally used for high-efficiency operations in the grinding and processing of burrs. However, the common grinding robots on the market have a single grinding head configuration, that is, the simple design of the grinding head causes the iron chips generated during the processing to fly around. , it is easy to cause the internal environment of the grinding chamber to be dirty, and because the iron chips after grinding are very small, it is inconvenient for the operator to centrally dispose of the fallen iron chips
