Real-time detecting system of geometrical morphology of airbag polishing head

Abstract

The invention discloses a real-time detecting system of the geometrical morphology of an airbag polishing head. The system comprises a soft polishing airbag head, a wireless displacement sensor and a computer, wherein the wireless displacement sensor comprises a group of distributed type distance sensing device, wireless transmitting circuit and wireless receiving circuit; the distance sensing device is installed inside the soft polishing airbag head close to the inner surface of an airbag; the wireless transmitting circuit is installed inside the distance sensing device; and real-time processing software installed inside the computer is connected with the wireless receiving circuit through a hardware interface of the computer. The system has the beneficial effects that the sensor is simple in structure and small in installation occupied space, and capable of rapidly reacting so as to be adaptive to the detection on the deformation of the inner surface of the airbag which rotates and changes in a high speed; the sensor does not contact with the inner surface of the airbag and does not influence the cutting force of the airbag, so that the surface roughness after the machining is not influenced; and thus the basis for the further research of an on-line track planning method is established.

Description

technical field [0001] The invention relates to a real-time detection system for the geometry of an airbag polishing head, which belongs to the field of flexible airbag polishing precision processing. Background technique [0002] Mold is an important basis for the development of manufacturing industry, and has broad application prospects in the fields of machinery, electronics, automobiles, light industry, building materials and national defense. Polishing is an important process in mold manufacturing, which plays an important role in ensuring mold quality and improving its service life. 65% of the mold cavity is a curved surface, of which 40% is a free-form surface. At present, the polishing of free-form surfaces of molds is mainly performed manually, which has low production efficiency and is difficult to ensure stable polishing quality. The current airbag polishing method can well solve this problem. Two of the main steps in the current airbag polishing process are thr...
