Surface Turbulence Polishing Device for Infrared Heating Constrained Components

Abstract

A curve-surface turbulence polishing device using infrared rays for heating a constraint component comprises the constraint component, an infrared heater, deformation sensors and a control cabinet. The constraint component is installed outside an artificial joint in a sleeved mode; a profiling flow passage with uniform thickness is formed between the inner surface of the constraint component and the outer surface of the artificial joint; the two ends of the constraint component are provided with a profiling flow passage outlet and a profiling flow passage inlet respectively, the infrared heater can move in three-dimensional space, the light spots of the infrared heater act on the constraint component, and the deformation sensors are arrayed on the outer surface of the constraint component. The profiling flow passage with uniform thickness is constructed through the constraint component and used for controlling abrasive grain flows; the constraint component is locally heated through the infrared heater, so that the size of the gap of the position, where the constraint component is heated, of flow passage is changed, and local machining intensity is controlled; due to the facts that the deformation sensors are arrayed on the outer surface of the constraint component, and the deformation sensors transmit the deformation data of the constraint component to the control cabinet, temperature control in the detecting process is achieved, polishing accuracy is high, and real-time performance is good.

Description

technical field [0001] The invention relates to the field of abrasive flow polishing processing, in particular to a turbulent flow precision processing device for a titanium alloy artificial joint. Background technique [0002] The smoothness of the artificial joint surface has a crucial impact on its function and service life. Therefore, the formed titanium alloy artificial joint prosthesis cannot be directly applied to the inside of the human body, and it needs to go through a series of grinding and polishing. Subsequent processing will finally obtain a high-precision and high-gloss surface, forming an artificial joint that fits well with human bones. [0003] The surface of the artificial joint is a complex curved surface with different curvatures, and the thermal conductivity and cutting performance of titanium alloy are poor. In the existing surface precision machining technology, most of the methods are difficult to apply. Since the abrasive flow can form a good profi...
