An adjustable fixture for repairing bevel gears by laser cladding

Abstract

The invention discloses an adjustable fixture used for repairing a bevel gear by laser cladding. The adjustable fixture comprises a Z-direction servo workbench and an X-direction servo workbench, wherein the X-direction servo workbench is provided with a Y-direction servo workbench; the Y-direction servo workbench is provided with an elevation adjustment system; the elevation adjustment system isprovided with a rotation adjustment system; the Z-direction servo workbench comprises a Z-direction workbench sliding plate; the Z-direction workbench sliding plate is provided with a laser used for repairing a snaggletooth bevel gear to be subjected to laser cladding on the rotation adjustment system. The adjustable fixture has the advantages of simple structure and novelty and reasonability in design. When the snaggletooth bevel gear is repaired, the elevation is adjusted to enable the snaggletooth bevel gear to be subjected to laser cladding to be positioned on a horizontal plane all the time, powder materials are more evenly accumulated, a cladding surface is positioned horizontally, and powder materials are unlikely to fall so as to be convenient for laser cladding; through the rotation adjustment system, the snaggletooth position of the bevel gear can be quickly rotated to be just below a laser head, and efficiency for repairing the snaggletooth bevel gear by the laser cladding is improved.

Description

technical field [0001] The invention relates to the technical field of laser cladding process clamping devices, in particular to an adjustable clamp for repairing bevel gears by laser cladding. Background technique [0002] With the development of science and technology, the application of laser technology in industrial production is becoming more and more mature. At present, it is mainly used in the field of mechanical maintenance to repair corroded and worn parts. Bevel gears are widely used in low-speed, heavy-load and power transmission environments between non-parallel shafts, especially in mining machinery, due to their advantages such as large overlapping coefficient, strong load-carrying capacity, high transmission ratio, stable transmission, and high transmission efficiency. mostly. [0003] During the use of large-scale mining machinery, due to the poor working conditions, most of them are low-speed and heavy-duty transmission, which makes the gear tooth surface e...

Problems solved by technology

[0005] When performing laser cladding on the bevel gears used in these large mining machinery, because there is no special fixture for laser cladding and repairing bevel gears, the bevel gear wear or broken teeth are usually repaired directly through the rotary machine tool. With a certain inclination angle, during the repair process, the laser powder is easy to slip due to the effect of gravity, which not only wastes the powder material but also makes the surface of the cladding broken tooth uneven, which affects the reliability of the gear and shortens the service life of the gear again.
