Description

Technical Field

[0001] This utility model belongs to the technical field of instrument panel processing equipment, specifically relating to a positioning fixture for grinding instrument panels. Background Technology

[0002] In the existing technology, the processed instrument panel is usually polished by hand to make the outer contour. However, due to the complex structure of the outer contour of the instrument panel, the efficiency of manual polishing is low, the product qualification rate is low, the rework rate is high, and the scrap rate is also high, which increases the production cost of enterprises and reduces their economic benefits.

[0003] In some cases, the processed dashboards are polished using automatic polishing equipment to polish the outer contours. However, when the polishing equipment directly polishes the outer contours of the dashboard, it is easy for some parts of the outer contours to be over-polished or for some parts of the outer contours to be left unpolished. Although the polishing efficiency is improved, the product qualification rate is still low, the scrap rate is high, the enterprise's production costs increase, and the enterprise's economic benefits decrease.
