Ordinary abrasive grinding wheel internal and external grinding machine

Abstract

The invention relates to a common abrasive grinding wheel internal and external grinding machine. The common abrasive grinding wheel internal and external grinding machine comprises a base, wherein components for implementing ascending, rotating and positioning of workpieces are arranged in the base; a main body rack is arranged on the base; and an internal grinding head component and an external grinding head component which are used for implementing ascending, descending, left-right movement and rotation of an internal grinding wheel and an external grinding wheel are arranged on the main body rack. The grinding machine is used for simultaneously machining internal holes and external circles of common abrasive cylindrical grinding wheels, synchronous 'feed' is realized, and machining efficiency is improved greatly. In addition, and by a grinding wheel loss online compensating component, machining precision is improved. The grinding machine is sealed integrally and is subjected to inflation cooling, and dust is removed under negative pressure, so that dry grinding is realized. The grinding machine is wide in application range and has relatively high popularization significance.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment processing, in particular to an internal and external cylindrical grinding machine with ordinary abrasive grinding wheels. Background technique [0002] In the ordinary abrasive tool industry, after the end face grinding of ordinary abrasive grinding wheels, it is necessary to grind the inner hole and outer circle. At present, there are many types of machine tools for machining inner holes and outer circles, mainly using two sets of equipment to process them separately. The inner hole and the outer circle, or the grinding wheel is clamped twice by one equipment to process the inner hole and the outer circle respectively, the machining accuracy is low, and the processing efficiency and automation degree are low. [0003] At present, internal and external cylindrical grinding machines are widely used in the field of mechanical processing. They mainly adopt vertical mechanism, use the le...

Problems solved by technology

[0002] In the ordinary abrasive tool industry, after the end face grinding of ordinary abrasive grinding wheels, the inner hole and outer circle need to be ground. At present, there are many types of machine tools for machining inner holes and outer circles, mainly using two sets of equipment to process them separately. The inner hole and the outer circle, or the grinding wheel is clamped twice by one equipment to process the inner hole and the outer circle separately, the machining accuracy is low, and the processing efficiency and automation degree are low

[0003] At present, internal and external cylindrical grinding machines are widely used in the field of mechanical processing. They mainly adopt vertical mechanism, use the left and right grinding wheels to grind the inner hole and outer circle of the workpiece, and the processed workpiece is metal, which is clamped by electromagnetic chuck and permanent magnetic chuck. One end face of the workpiece, the dust-proof design is mainly for iron filings, etc., while ordinary abrasive grinding wheels can only be clamped by clamping two end faces, and the diameter of the grinding wheel is generally large, and the grinding dust is large, so the mechanical processing field Internal and external cylindrical grinders cannot be used for grinding the internal and external circles of ordinary abrasive grinding wheels
