Description
Technical Field
The invention relates to the technical field of clamping devices in laser cladding processes, in particular to an adjustable clamp for repairing a bevel gear by laser cladding.
Background
With the development of scientific technology, the application of laser technology in industrial production is becoming mature, and the laser technology is mainly used for repairing corrosion and wear parts in the field of mechanical maintenance at present. The bevel gear has the advantages of large overlapping coefficient, strong bearing capacity, high transmission ratio, stable transmission, high transmission efficiency and the like, and is widely applied to the environment of low-speed heavy load and power transmission between non-parallel shafts, particularly the environment of mining machinery.
In the use of large-scale mining machinery, because the operating mode is relatively poor, mostly low-speed heavy load transmission for the gear flank of tooth is damaged or is out of shape fast easily, and what's more, when improper use causes the gear to transship, the teeth of a cogwheel probably appears the teeth of a cogwheel rupture under the abrupt loading effect, and then leads to whole gear failure to scrap, therefore the gear becomes one of the main vulnerable part in the mining machinery use. It is statistical that mining machinery failure due to gear failure accounts for about 10% of the total failure. It is known that the machining cost is generally high due to the complex machining and manufacturing of the bevel gear, but the cost for repairing the bevel gear through laser cladding is generally only 1/4 or even lower than the manufacturing cost. Therefore, in order to prolong the service life of the bevel gear in mining machinery and improve the comprehensive use performance of the bevel gear, the laser cladding repair and reuse of the worn bevel gear even with broken teeth is a necessity.
Since the 20 th century and the 80 th era, the laser cladding technology is rapidly developed and becomes a hot spot of domestic and foreign research. The laser cladding remanufacturing technology is a high and new technology which mainly takes a laser cladding technology to repair and remanufacture damaged waste parts losing use values as base materials. The technology utilizes a laser generator to emit high-energy laser beams to slightly melt the surface of a processed part in a short time, so that powder preset on the surface of the part or alloy powder and alloy wires synchronously conveyed with the laser beams are completely melted, and a cladding layer well combined with a matrix is obtained through rapid solidification, thereby achieving the recovery of the geometric dimension and the original performance of the surface of the part. The laser cladding remanufacturing technology can quickly prepare a cladding layer equivalent to the performance of a base material, and endows the parts with the performances of high temperature resistance, corrosion resistance, wear resistance and the like. The production mode of laser cladding repair is beneficial to reducing cost and resource consumption and environmental pollution, and is a green project which accords with the strategy of sustainable development.
When the bevel gears for the large mining machinery are subjected to laser cladding, because no special fixture for repairing the bevel gears by laser cladding is available, the bevel gears are generally directly subjected to bevel gear abrasion or broken tooth repair by a rotary machine tool, and because the bevel gears have a certain inclination angle, laser powder easily slides down due to the action of gravity in the repair process, so that powder materials are wasted, the cladding broken tooth surface is not uniform, the reliability of the use of the gears is influenced, and the service life of the gears is shortened.
