Technical Field

The invention relates to laser-assisted cold spraying processing equipment, in particular to an automatic movable frame device for laser-assisted low-pressure cold spraying.

Background

The low-pressure cold spraying is a spraying technology based on the aerodynamic principle, the principle is that low-pressure gas is used for carrying powder particles into high-speed airflow, the high-speed airflow is accelerated through a Laval nozzle to generate gas-solid two-phase flow, the powder particles are accelerated through a spray pipe and then collide with a substrate at a high speed in a solid state, and the powder particles are deposited on the surface of a base body to form a coating through generating strong plastic deformation, and the cold spraying is a coating formed by relying on the kinetic energy of the particles. Therefore, the technology has the advantages that 1) the heating temperature of the spraying carrier gas is far lower than the melting point of the powder particles, and the particles basically have no phenomena of oxidation, phase change, burning loss, grain growth and the like. 2) The heat influence of the coating on the substrate is small, so that the thermal stress between the coating and the substrate is reduced, and the residual stress between the coating and the substrate is small and mainly compressive stress. 3) The powder which is not utilized in the spraying can be recycled, and the method is economical and environment-friendly. However, the low pressure cold spray technique results in a less tight bond between the coating and the substrate and a higher porosity of the coating due to its low pressure.

The laser-assisted low-pressure cold spraying technology is a novel spraying and remanufacturing technology, and the laser-assisted low-pressure cold spraying equipment mainly comprises a low-pressure gas source, a powder feeder, a Laval nozzle, an experiment box, a laser, a temperature sensor, a processing matrix, a deposition coating and a powder recovery device. The laser heating device combines the powder beam and the substrate with the laser heating of the deposition area, and introduces laser to replace carrier gas for preheating in the low-pressure cold spraying process to heat and soften the powder particles and soften the substrate. The laser-assisted low-pressure cold spraying technology not only overcomes the defects of untight combination, low efficiency, high porosity and the like of a low-pressure cold spraying coating, but also can realize the preparation of a high-hardness material coating and expand the application range of materials and matrixes.

However, although the current laser-assisted low-pressure cold spraying technology is convenient to move, the moving frame in the working process is usually a mechanical arm, which is not beneficial to field repair and remanufacture, and the cost of the mechanical arm is also high. There are also hands held operations, but this method does not allow control of the distance of spraying, resulting in undesirable results and also being extremely dangerous. In addition, one person can realize single-pass spraying operation through the guide rail, but the method cannot be accurately controlled, accurate overlapping and laminating experiments cannot be carried out, the spraying distance cannot be accurately controlled, and the human error is large. The methods have the problems of insufficient automation and insufficient accuracy, are not beneficial to large-scale industrial application and lack of popularization value.

Disclosure of Invention

In order to solve the technical problems, the invention aims to provide an automatic movable rack device for laser-assisted low-pressure cold spraying. The device can realize intelligent automatic control, can realize the quick accurate adjustment of spraying distance, can realize automatic movement on the plane to realize the intelligent movement of XYZ three direction, accurate realization moving distance control obtains wanted spraying and laser scanning route, thereby can carry out overlap joint and stromatolite experiment, and the cost is with low costs, and is quick high-efficient, can satisfy experiment demand and industrial application.

The nozzle mounting plate 31 and the laser head mounting plate 32 are respectively arranged on the end surface of the Y-direction slider facing to one side of the connecting rod.

The lifting electric push rods 11 share one set of lifting electric push rod power supply and the lifting electric push rod driving main switch 13, and synchronous lifting of the lifting electric push rods is achieved.

The power supply and the driving signal of the motor controlled by the X-direction position adjusting mechanism control switch 214 and the Y-direction position adjusting mechanism control switch 224 are kept consistent, so that the two X-direction sliders 213 are kept in step, and the Y-direction position adjusting mechanism is always perpendicular to the X-direction guide rail 211.

The X direction refers to the axial direction of the X-direction guide rail; the Y direction refers to the horizontal direction which is vertical to the X-direction guide rail; the Z-direction or vertical direction is a direction and refers to a direction perpendicular to both the X-direction and the Y-direction.

The X-direction driving motor and the Y-direction driving motor are stepping motors and are driven by corresponding drivers to rotate forward and backward and regulate speed.

The working principle of the invention is as follows: when an experiment is carried out after the experiment is built, the nozzle fixing part and the laser head mounting plate are firstly mounted on two sides of the Y-direction sliding block facing the connecting rod through the connecting bolt group, then an experiment base material is fixed, the nozzle and the laser head are respectively mounted on the nozzle fixing part and the laser head mounting plate, the position of the spray gun is adjusted through four vertical threaded holes of the nozzle fixing part, and the angle of the laser head is adjusted through two sections of concentric arc grooves, so that the laser beam is coupled with the powder beam. The control switch of the lifting electric push rod driver is started, the extension lengths of the four sets of lifting electric push rods can be synchronously adjusted, and the spraying distance is further adjusted. And then starting an X-direction driving motor control switch and a Y-direction driving motor control switch, adjusting the spraying initial position, programming a program in the controller in advance according to requirements, and outputting corresponding control signals to the X-direction position adjusting mechanism, the Y-direction position adjusting mechanism and the lifting electric push rod so as to control the movement sequence, time, speed and direction of the three motors, further control the spraying movement track, and start an experiment by starting a controller power switch of the control device.
