Abstract

The invention provides a spiral spring fixture. The spiral spring fixture comprises two oppositely arranged clamping plates which are arranged on a spring disassembling and assembling device, oppositely arranged through holes which are formed in the two clamping plates, a locking bolt which is arranged in the two through holes in a penetrating manner and a nut which is arranged on the locking bolt. The spiral spring fixture further comprises two rotatable clamping heads which are oppositely arranged on the two clamping plates, wherein threaded grooves which are adaptive to an outer circumferential surface of a spiral spring are formed in working faces of the clamping heads. The spiral spring fixture is used for clamping the spiral spring to prevent the spiral spring from easily popping up during disassembling and assembling, and the personal safety of operators is guaranteed.

Description

technical field [0001] The invention relates to a spring clamp, in particular to a coil spring clamp, which is applied to a spring dismounting device and aims at the disassembly and assembly of coil springs on different devices.
