Track surface coating clamp

Abstract

The invention discloses a track surface coating clamp. The track surface coating clamp comprises a base, wherein a supporting seat is arranged on the base in a sliding mode; a placing table used for placing parts is arranged on the supporting seat in a sliding mode; clamping blocks are movably arranged on the two sides of the supporting seat; a driving mechanism used for driving the clamping blocks to move relatively is further arranged on the supporting seat; the driving mechanism comprises a hydraulic column I; transmission arms are hinged to the two sides of the piston end of the hydrauliccolumn I; the transmission arms are hinged to the clamping blocks through connecting rods and displacement transmission arms in sequence; fixing seats are further arranged on the two sides of the supporting seat; and the displacement transmission arms are rotationally arranged on the fixing seats. According to the track surface coating clamp, a workpiece is clamped through the clamping blocks on the two sides, a heating device on a positioning plate can be used for preheating the workpiece, so that a better cladding effect in the laser cladding process is realized, and common process defects in the laser cladding process of cracks are effectively controlled.

Description

technical field [0001] The invention relates to the field of mechanical processing tooling, in particular to a laser remanufacturing fixture for rail wear-resistant surface cladding. Background technique [0002] Laser cladding is an efficient and precise coating preparation process with high energy density and low deformation using laser beam as heat source, which is an important application of laser processing technology in the field of surface engineering. This technology irradiates the metal surface with a high-intensity laser beam, and interacts with the metal substrate through the laser beam. The metal substrate absorbs heat energy to melt and solidify the metal to form a well-fused surface coating, improving the surface properties of the substrate. When the laser beam touches the metal substrate, its heat is transferred to the surface of the workpiece and below through heat conduction, the substrate melts in a very short time and forms a molten pool, and at the same t...
