Robotic machining of workpieces using scraping process - involves manipulating workpiece so that features to be machined are drawn past scraper blade under controlled pressure

摘要

The workpiece (14) is gripped by a robot (11) and manipulated so that the surfaces to be machined are drawn past the scraper blade (17) of a scraping tool (16) held in a fixed tool-holder (15',15''). Machining may involve only minimal change to the surface form, e.g. the removal of burrs and chamfering of edges, but new features may also be produced. The scraper blade (17) is loaded against the workpiece surface by a pneumatic or hydraulic positioning cylinder (19) which may act only as a passive spring element or as an active force and position controller with a power source. USE/ADVANTAGE - Robotic scraper machining tool. By contrast with brushing etc. complex forms such as slots can be reliably deburred. Release of toxic dust is minimised. Simple, effective control of quality. AN 93206620 TI Adjustable press for rapid changeover cramping tools - has crank access unit with adjustable elements to set distance relative to tooling AB DE4239930A A crimping press system is used to fix a crimped connector to wires and has crimping tools that can rapidly be changed and adjusted. The tools are mounted on a crank press and the stroking distance can be adjusted. The crank press stage is supported on an arm from the tool mounted base. Side members carry adjusters for final setting of the distance. ADVANTAGE - Allows rapid tool changeover and setting.
