A surface powder laying height control device for aero-engine blade remanufacturing comprises a vertically-arranged machine body, wherein the machine body is movably sleeved with a sliding sleeve, and the sliding sleeve is provided with a height measurer; a pair of lower clamping plates is arranged at the front side of the lower portion of the machine body, a pair of upper clamping plates is correspondingly arranged above the pair of lower clamping plates, a left powder blocking film is arranged between the lower clamping plates and the upper clamping plates at the left side, a right powder blocking film is arranged between the lower clamping plate and the upper clamping plate at the right side, and a front powder blocking film is arranged at the front sides of the pair of lower clamping plates and the front sides of the pair of upper clamping plates. a space for accommodating powder is formed among the left powder blocking film, the right powder blocking film, the front powder blocking film and the front side surface of the machine body; a distance adjusting bolt seat is arranged on the surface of the front side of the sliding sleeve, and a distance adjusting bolt is vertically arranged in the upper clamping plates and the adjusting bolt seat in a penetrating manner; and fixing bolt holes are formed in the rear side surface of the sliding sleeve, and the tail ends of fixing bolts abut against the rear side surface of the machine body. According to the surface powder laying height control device, the distance between the upper clamping plates and the lower clamping plates is adjustable, the needed powder laying height can be obtained through adjustment, and the distance adjusting process is stable and reliable.
Description
technical field [0001] The invention relates to a surface powder coating height control device for aeroengine blade remanufacturing. Background technique [0002] In the powder-spreading laser cladding technology, it is often necessary to control the powder-spreading height, and match the laser power according to the powder height to realize the control of the cladding layer height. In many personalized productions, such as powder cladding on the surface of existing workpieces, the powder coating height needs to be adjusted several times to match different process parameters. The more commonly used control method is to process two feeler gauges with the required height, and Place the feeler gauge on the surface of the workpiece after a certain distance, pour the powder into the gap between the feeler gauges, and scrape off the excess powder higher than the height of the feeler gauge with a scraper. At this time, the height of the powder is the height of the feeler gauge. In...
