Abstract
The utility model provides a magnetic core fixing device with high production efficiency. The magnetic core fixing device comprises a first clamping piece and a second clamping piece. A cylinder with a fixing key is arranged on the first clamping piece. A circular hole with a key groove is correspondingly formed in a magnetic core. A groove used for fixing the magnetic core is formed in the second clamping piece. A second groove used for fixing the cylinder is formed in the bottom of the groove. A permanent magnet is arranged in the second groove and is sucked to the cylinder. The magnetic core fixing device is simple in structure, convenient to fix and disassemble, time-saving and high in production efficiency.
Description
Technical field
The utility model relates to a kind of magnetic core fixing device.
Background technology
The extensive use of electromagnetic product such as transformer and relay and social production and various fields in life have the large market.Such electromagnetic product generally comprises a magnetic core and a coil that is set around this magnetic core.During making, the rotating shaft by retaining elements such as screw rod and nut are fixed in automatic coil winding machine with magnetic core is set around wire rod on the magnetic core by the rotating shaft of rotating automatic coil winding machine again.After coiling is finished, unclamp the screw rod and the nut that screw togather again, take off the magnetic core around intact coil.In the manufacturing process, the fixing and demolition magnetic core is wasted time and energy, and production efficiency is low.
