Above-mentioned a kind of template sewing machine electromagnet, the internal diameter of this elastic washer is greater than the diameter of flexible iron core, is less than the external diameter of regulating nut.
Above-mentioned a kind of template sewing machine electromagnet, this housing comprises shell and is located at the end cap at shell two ends, and this end cap offers the through hole corresponding with flexible iron core.
The beneficial effects of the utility model are: by adding inner metal sleeve between coil rack and flexible iron core, and this inner metal sleeve and coil rack are fixedly linked, and connect with lazy tongs core retainer plate and be flexibly connected, therefore after the utility model works long hours, heat on coil rack can be dispelled the heat by inner metal sleeve in time, another reverse side, inner metal sleeve has good mechanical strength, effectively can support coil rack, thus can eliminate because coil rack crosses thermal expansion, cause its internal diameter to reduce, thus cause the situation blocking flexible iron core to occur.Isochrone ring framework adopts integrated formed structure, also simplifies structure of the present utility model further, improves its practicality.In addition, the utility model can realize self-locking by two regulating nuts and platform and fastening nut, thus can ensure its reliability of locating, and can effectively eliminate the noise produced in knockout process by cushion and elastic washer simultaneously.To sum up namely, the utility model has noiselessness, locates reliable and practical advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
Further understand for making to have architectural feature of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As depicted in figs. 1 and 2, a kind of template sewing machine electromagnet, the flexible iron core 4 comprising housing 1, be located at the coil rack 2 of housing 1 inside, be set around the solenoid 3 on coil rack 2 and match with solenoid 3, its middle shell 1 comprises shell 11 and is located at the end cap 12 at shell 11 two ends, and this end cap 12 offers the through hole corresponding with flexible iron core 4.
Coil rack 2 is hollow structure, this flexible iron core 4 is socketed with coil rack 2 and is flexibly connected, the two ends of this flexible iron core 4 are all run through the end cap 12 of housing 1 and are extended to the outside of housing 1, inner metal sleeve 5 is provided with between this coil rack 2 and flexible iron core 4, this inner metal sleeve 5 is copper inner sleeve, this inner metal sleeve 5 is fixedly linked with coil rack 2, and this inner metal sleeve 5 is socketed with flexible iron core 4 and is flexibly connected.After the utility model works long hours, heat on coil rack 2 can be dispelled the heat by inner metal sleeve 5 in time, inner metal sleeve 5 has good mechanical strength simultaneously, can reliably support coil rack 2, thus can eliminate because coil rack 2 crosses thermal expansion, cause its internal diameter to reduce, and cause the situation blocking flexible iron core 4 to occur, therefore the utility model has practical advantage.
Coil rack 2 is formed in one structure, this coil rack 2 is provided with side by side two winding slots, be set around the solenoid 3 in described two winding slots around on the contrary.By coil rack 2 is designed to integrated formed structure, its structure can be simplified on the one hand, be convenient to assembling; On the other hand, the reliability and stability of utility model works are also made also to improve further.
