Operating platform device for laser cladding

Abstract

The invention discloses an operating platform device for laser cladding. The operating platform device comprises a lifting platform and a cooling box body. The inner bottom of the cooling box body is provided with a baffle pipe extending to the top of the cooling box body. A cooling liquid inlet I and a cooling liquid inlet II are formed in the side wall of the cooling box body. Two cooling liquid outlets are formed in the top of the cooling box body. The lifting platform comprises a lower plane attached to the inner bottom of the cooling box body, a cladding platform and four lifting devices located between the lower plane and the cladding platform. Each lifting device comprises a supporting rod I connected with the upper surface of a lower platform, a cardan shaft connected with the lower surface of the cladding platform, and a supporting rod II connected with the cardan shaft. By means of the operating platform device for laser cladding, the cladding platform can be tilted in a lifting mode and be obliquely rotated, the environment temperature in the cladding process is guaranteed, the 'collapsing' phenomenon of a cladding layer is prevented, 'splashed' powder in the cladding process can be stopped, and thus the effect of powder collection can be achieved.

Description

technical field [0001] The invention relates to an operating platform device for laser cladding with adjustable height angle, controllable temperature and recyclable waste materials. Background technique [0002] Laser cladding technology is a new surface modification technology that emerged with the development of high-power lasers in the 1970s. This technology rapidly heats and melts alloy powder or ceramic powder and the surface of the substrate under the action of laser beams. A rapid prototyping method for surface coatings that are metallurgically bonded to the base material. Using laser cladding technology, functional parts with arbitrary complex shapes, good mechanical properties and high dimensional accuracy can be obtained, which are suitable for small batches and customized complex functional parts. [0003] Laser cladding forming technology is widely used in the processing and manufacturing of important parts of automobiles and aerospace, maintenance, complex spe...

AI Technical Summary

Problems solved by technology

[0013] 1. During the cladding process, the cladding working platform cannot be moved. Only by moving the position of the laser head to find the origin position of cladding to start working. This adjustment operation needs to adjust the position of the laser head through the handle of the robot, which needs to be aimed with the naked eye Position and then perform origin calibration. If the operation is improper, the laser head will hit the processing operation plane and damage the laser head.

In addition, due to the limitations of the equipment, if it is necessary to clad the workpiece at a certain angle to the horizontal direction, the cladding operation process will not be possible due to the absence of supporting equipment;

[0014] 2. The temperature of laser cladding is generally about 1000°C. When the number of cladding layers is small, the temperature dissipates quickly. As the layer thickness gradually increases, the temperature and heat accumulation phenomenon gradually becomes serious, which leads to the upper part of the workpiece The temperature and heat accumulation are high, and the "collapse" phenomenon will appear during the cladding process, which will affect the molding effect;

[0015] 3. When the powder feeding amount and scanning speed reach a certain value, the powder ejected by the laser head is faster and the powder amount is relatively large. Unable to collect back, a lot of powder is wasted
