Abstract

The invention provides a two-station processing device for grinding wheel dressing and grinding processing, belongs to the technical field of ultra-precision machining, and aims at solving the problems that a small-size ball end grinding wheel is subjected to offset after being mounted and the abrasion on a fine-grain grinding wheel in processing leads to the reduction of processing quality and surface precision. The device is characterized in that T-shaped grooves are formed at intervals in the upper surface of a worktable, wherein two CCD monitoring devices, an electric sparking dressing device and a workpiece spindle clamping part are fixed to the worktable by the T-shaped grooves through T-shaped groove bolts; a workpiece spindle transition plate is positioned on the worktable through a positioning block and is fastened through the T-shaped groove bolts; the workpiece spindle clamping part is connected to the workpiece spindle transition plate; a workpiece spindle is mounted into a clamping hole of the workpiece spindle clamping part and is clamped and fastened through a screwing bolt; an axis of the workpiece spindle is in the direction parallel to that of the T-shaped grooves; workstation protecting covers are arranged around the workable; workpiece spindle device protecting covers are arranged at the inner sides of the worktable protecting covers; an organ shaped protecting cover of which the upper side edge height can be adjusted up and down is arranged between the workpiece spindle and the electric spark dressing device. The device is applicable to the grinding wheel dressing and grinding processing.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision machining. Background technique [0002] With the increasing development of science and technology, ultra-precision machining technology is playing an increasingly important role in many high-tech fields such as national defense industry, aerospace technology, optics and communication, and new energy. At the same time, these fields have also put forward higher and higher requirements for the processing quality of the required parts. The materials used are becoming more and more diverse, and the structure is correspondingly more and more complicated. These characteristics make the processing of such parts difficult. increase accordingly. Most of these parts are processed by ultra-precision grinding. [0003] When the overall size of this kind of parts is small, due to the complex structure, the tool grinding wheel is easy to interfere with the workpiece during processing, and its arc curv...
