Problems solved by technology

It is necessary to manually disassemble the measuring device for subsequent milling. For single-piece and small-batch production, the processing efficiency is low and does not meet the requirements of flexible manufacturing.
In addition, the system cannot perform quality inspection on finished products under the same platform

Embodiment Construction

[0019] The invention integrates both non-contact and contact sensors. On the one hand, it uses the characteristics of fast non-contact measurement and large amount of data to quickly calculate the spatial position relationship between the target and the design coordinate system, which is used to generate machining G codes that can be directly applied in the machine tool coordinate system; on the other hand, use With the characteristics of high precision of contact measurement, the quality inspection of processed products is carried out.

[0020] Such as figure 1 As shown, the free-form surface part processing system based on multi-sensor integrated measurement includes four working components: surface measurement component, point cloud processing component, surface processing component and quality inspection component.

[0021] The surface measurement component integrates both non-contact and contact sensors for discrete measurement of the target to be measured. The surface ...

Abstract

The invention discloses a free-form surface part processing system based on the multi-sensor integrated measurement technology. A non-contact type sensor and a contact type sensor are integrated to form a surface measuring component, a surface processing component is provided with a milling cutter, and the surface measuring component is connected with the surface processing component by a linear guide rail. A point-cloud processing component is used for realizing geometric processing for point-cloud data obtained by the non-contact type sensor, and provides processing G codes which can be directly actuated by a current work table to the surface processing component for processing. The surface measuring component measures a workpiece in a non-contact manner, and then measures a product which is obtained by means of fine processing in a contact manner. A quality detecting component is used for comparing errors of measured data obtained by the contact type sensor and obtains results of the quality of the product. The non-contact type sensor and the contact type sensor are integrated, an integrated function of 'measuring, processing and detecting' is realized on the same machine tool, manual intervention is omitted in a total process, and processing efficiency and automation degree are improved.

Description

technical field [0001] The invention relates to the field of processing technology, in particular to a free-form surface part processing system based on multi-sensor integrated measurement. Background technique [0002] In recent years, free-form surface parts (such as automobile panels and aeroengine blades, etc.) have been widely used in industries such as automobiles, aircrafts, and home appliances. The rapid processing and manufacturing of free-form surface parts has attracted widespread attention. For the target to be measured, it is first necessary to establish the positional relationship of the target between the machine tool coordinate system and the design coordinate system. The traditional method uses a non-contact method to scan the blank as a whole, and calculates the spatial rigid body transformation relationship to make the processing files in the design coordinate system take effect in the machine tool coordinate system; use the contact method to perform conta...
