Beveling device for inlet and exhaust valves of internal combustion engines

Abstract

The invention discloses a beveling device for inlet and exhaust valves of internal combustion engines. The beveling device comprises a material bin, a discharging mechanism, a longitudinal chute, two threaded rollers, a rubber plate and a beveling grinding wheel, wherein the material bin is used for containing horizontal core rods transversely arranged, and a discharge port is formed in the lower part of the front side of the material bin; the upper end of a baffle of the discharging mechanism is bent for forming an acute angle towards the side away from the discharge port; the core rods slowly roll down along the longitudinal chute, the material bin communicates with the upper end of the longitudinal chute through the discharge port, and a horizontal supporting part is arranged at the lower end of the longitudinal chute; the threaded rollers are provided with arc-shaped threaded grooves, the diameters of section arcs of the threaded grooves are equal to the diameters of the core rods, the axial staggering distance of the two threaded rollers is an integral multiple of the product of the distance between rotation shafts of the two threaded rollers and tangent values of lead angles of the two threaded rollers, and the upper edges of the two threaded rollers are flush with the upper edge of the horizontal supporting part in vertical height; the rubber plate is horizontally and fixedly arranged. The beveling device is high in automation degree, high in efficiency and stable in beveling quality.

Description

technical field [0001] The invention relates to the field of auto parts production, in particular to a chamfer device for intake and exhaust valves of an internal combustion engine. Background technique [0002] With the continuous development of the automobile industry, the continuous improvement of engine speed, power and torque has higher requirements on the structure and requirements of intake and exhaust valves. In the prior art, the intake and exhaust valves generally consist of a disc and a rod with a lock clip groove. At present, when the intake and exhaust valves are produced from the core material, after the long core material rod is cut to a certain length of mandrel, it is necessary to grind the end face of the rod before chamfering. At present, grinding is mainly carried out manually on the grinding wheel. This method has low degree of automation, low efficiency and unstable quality. Therefore need badly a kind of degree of automation height, efficient height,...
