Description

TECHNICAL FIELD

[0001] The utility model belongs to laser remelting preheating platform technical field, concretely relates to a thermal barrier coating laser remeltement preheating platform. BACKGROUND

[0002] Thermal barrier coating is a ceramic coating, which is deposited on the surface of high-temperature-resistant metal or superalloy. The thermal barrier coating plays a heat-insulating role for the base material. When the thermal barrier coating is processed, a laser remelting processing method is usually used to make it have better performance. In addition, the thermal barrier coating needs to be preheated when it is processed by laser remelting. The existing laser remelting preheating platform is a device used for preheating when the thermal barrier coating is processed. It is convenient to uniformly preheat the surface of the preheating platform plate by tightly pressing the heating wire.

[0003] According to the preheating platform of the thermal barrier coating laser remelting equipment disclosed in the granted patent application No. 202120801991.9, when the existing laser remelting preheating platform is used for preheating processing of the thermal barrier coating, the preheating platform plate is directly clamped and installed on the surface of the base. The top rod is elastically connected by the elasticity of the spring, and the heating wire is preheated by the top rod contacting the lower surface of the preheating platform plate. When the top rod is pressed for a long time after installation, the spring is deformed and pressed by the downward pressure of the top rod, causing some springs to deform under long-term stress, resulting in a decrease in spring force. The top rod cannot drive the top rod and the heating wire to elastically and tightly contact the inner surface of the preheating platform plate for heating. This causes some positions of the preheating platform plate to be unable to heat and preheat, thereby affecting the preheating effect of the heating wire when the preheating platform is used for laser remelting operation of the thermal barrier coating. Therefore, the utility model provides a thermal barrier coating laser remelting preheating platform. UTILITY MODEL CONTENTS

The top rod cannot drive the top rod and the heating wire to elastically and tightly contact the inner surface of the preheating platform plate for heating, causing some positions of the preheating platform plate to be unable to heat and preheat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a movable and adjustable pressing contact mechanism, when the heating wire cannot contact the inner surface of the preheating plate due to the downward pressure of the top rod and spring during long-term use of the laser remelting preheating table, the three lead screws can be moved simultaneously to move the movable plate. When the movable plate moves, it moves the fixed base plate and moves the upright and top rod upward. Under the slight elasticity of the spring, the heating wire is still in contact with the inner surface of the preheating plate. This facilitates uniform heating of the heating wire by keeping it in contact with the inner surface of the preheating plate during long-term operation, thus improving the pressing contact preheating effect of the laser remelting preheating table during the laser remelting of thermal barrier coatings.
