Description

TECHNICAL FIELD

[0001] The utility model relates to piston processing technical field especially a piston pin collecting device. BACKGROUND

[0002] Piston pin as the core kinematic pair component of engine needs to bear periodic gas explosion pressure and reciprocating inertia force in operation. In order to meet the double needs of surface wear resistance and core impact toughness of service condition, modern piston pin generally adopts carburizing quenching process to form gradient hardness structure, that is, the surface forms 0.8-1.2mm deep high hardness layer, and the core keeps medium hardness. Although this heterogeneous material property improves product performance, it brings special challenges to the logistics link in the production process.

[0003] In the large-scale production scene, the piston pin processing line generally adopts high-beat production mode of 60-100 pieces per minute. The existing collecting device adopts the structural design of open material channel combined with gravity chute. In the high-speed discharging process, the piston pins are prone to multi-angle collision due to unconstrained movement, and micro-crack defects may occur in the surface hardening layer. When the collision energy exceeds 5J, it will cause visible indentation. This surface damage will cause two problems in the engine assembly stage: first, the stress concentration effect of the damaged part makes the piston pin and the small head hole of the connecting rod cooperate easily; Second, the surface micro-protrusions will scratch the piston pin hole plating layer during operation, causing abnormal wear.

[0004] Although the polyurethane gasket protection scheme commonly used in the industry can reduce the collision damage caused by the falling of the piston pin, it needs to clean the material accumulation at all times to prevent collision damage between the piston pins. The existing scheme cannot effectively solve the collision damage problem of the piston pin surface during the collecting process while ensuring high production efficiency. UTILITY MODEL CONTENTS

[0038] The piston pin is a core key component of an engine, and bears a huge explosion thrust, which requires the piston pin to have not only good rigidity but also good toughness, so that the piston pin surface has a high hardness layer and a core with low hardness. Since the piston pin production rhythm is fast, the piston pin directly falls into a collecting box after being connected to a washing machine from a grinding machine, and the piston pins may collide with each other, so that the piston pin outer circle is scratched. When the piston pin is assembled and used, the piston pin cannot be assembled, or the piston pin scratch phenomenon occurs on the inner wall of the piston hole. The piston pin scratch phenomenon is also a difficult problem in the piston pin processing industry. To solve this production problem, the present application provides a piston pin collecting device.
