Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of clasp spring installation, and concretely relates to a clasp spring installation workpiece convenient to use. BACKGROUND

[0002] Clasp spring is also called retaining ring or snap ring, which belongs to a kind of fastener, is installed in the shaft slot or hole slot of machine or equipment, and plays the role of preventing the axial movement of parts on the shaft or hole. It is mainly divided into two types of shaft and hole. The shaft clasp spring is open ring, the inner hole has taper and the outer side has ear-shaped protrusion, when installing, the inner diameter is smaller than the shaft diameter by using tool contraction, and is embedded into the shaft slot and fixed by elastic expansion outward. The hole clasp spring is also open ring, the outer circle has taper, the inner side has ear, when installing, the outer diameter is expanded by using tool, and is placed into the hole slot and fixed by elastic contraction. The clasp spring is generally made of spring steel such as 65Mn and 50CrVA, and is treated by quenching and tempering, so as to have high elastic limit and fatigue limit. It is widely used in automobile engine, transmission, transmission system of mechanical manufacturing, bearing seat, motor and compressor of household electrical products and other parts. The installation and disassembly need to use clasp spring pliers, and the operation should be careful to prevent damage to the clasp spring and other parts.

[0003] At present, the clasp spring is installed by workers manually, but there are many difficulties in manual installation of the clasp spring. First, the operation space is severely limited.

Secondly, the clasp spring is easy to deform. Because it has great elasticity, a large external force needs to be applied by using the clasp spring pliers to change its shape during installation. However, if the force is uneven or too strong, the clasp spring will be deformed due to excessive local stress, resulting in size change, unable to be normally embedded into the slot, and even directly scrapped.
