Abstract
The utility model relates to a reversible sewing electromagnetism controlling device of the industrial intellectualization computer sewing machine, which belongs to the industrial intellectualization computer sewing machine field. The reversible sewing electromagnetism controlling device is composed of a conducting magnet, an existing magnet, a guide and a movement part, wherein the structure of an iron core with large diameter and flange is adopted, and the structures of a guide increasing piece, a combined-type magnet conducting body and an end cover and a magnet conducting ring interference fit etc. are added. The structure of the device is simple, the material using can be saved, the suction force can be strengthened, the movement blocking of the iron core can be avoided, and the operating requirement of the industrial intellectualization computer sewing machine to the reversible sewing electromagnetism controlling device can be met.
Description
Technical field:
The utility model relates to industrial computer Sewing machines field, especially backstitches electromagnetic control apparatus in the industrial computer Sewing machines.
Background technology
Industrial computer Sewing machines in the market backstitches electromagnetic control apparatus, exists volume big, the manufacturing cost height, and shortcoming such as response speed is slow, and suction is little can't satisfy efficient height, the fast and inexpensive characteristics of action of the requirement of new generation of industrial computer controlled sewing machine.
Summary of the invention
To be solved by this invention provide a kind ofly can satisfy the desired efficient height of new generation of industrial computer controlled sewing machine, action is fast, suction is big and cost is low backstitches the intelligent electric magnetic controller.
In order to achieve the above object, the technical solution adopted in the utility model is: backstitch the intelligent electric magnetic controller and mainly cooperate and constitute by magnetic conduction, excitation, guiding, motion four parts, wherein the magnetic conduction part by magnetic conductor and end cap constitute, the excitation part is made of coil, skeleton and power line etc.; Targeting part by fairlead, prerotation vane constitute, motion parts is made of iron core, bar, pin and cushion pad etc.
Iron core adopts the structure of major diameter, big flange, has effectively increased suction.End cap and magnetic conductor adopt interference fit.Prerotation vane and end cap interference fit are with the bar matched in clearance.Fairlead and iron core adopt matched in clearance, thereby form prerotation vane cooperates guiding with fairlead two guidance modes, effectively disperse stressed.Surface treatment is nickel plating.
Excitation part and magnetic conduction partly constitute a closed magnetic circuit system, produce magnetic field behind the coil electricity, i.e. magnetic potential, and magnetic conduction partly constitutes magnetic circuit, thus produce a powerful magnetic field.Iron core moves under the effect of magnetic force.
The beneficial effects of the utility model: it is specifically long-pending little to backstitch electromagnetic control apparatus, only be to backstitch about 1/2 of electromagnetic control apparatus volume on the existing market, response speed and suction but are 1.5 times that tradition backstitches electromagnetic control apparatus, reach 130N, manufacturing cost is about tradition and backstitches 1/2 of electromagnetic control apparatus, economic benefit is very considerable, and every performance meets the demands fully.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Backstitch on the electromagnetic control apparatus basis in Fig. 4, tradition shown in Figure 5, the utility model has been done following improvement, makes as Fig. 1, Fig. 2, shown in Figure 3 backstitches iron core among electromagnetic control apparatus and Fig. 6:
1, to motion parts, adopt the diameter that strengthens iron core (3), and the one end is processed into a flange (19), flange (19) plays the auxiliary magnetic pole effect, can heighten to add the suction of electromagnetic control apparatus.
2,, increase prerotation vane (4), prerotation vane and bar matched in clearance to targeting part, iron core (3) and fairlead (11) matched in clearance, form two guidance modes and disperse stressedly, improve iron core (3) intermittent movement response speed, prevented that iron core (3) is stuck because of unbalance stress.
3, magnetic conductor (19) is changed into welding after the combination by magnetic guiding loop (7) and flange (8) by overall structure make, reduced difficulty of processing and cost, improved working (machining) efficiency greatly.
4, end cap (6) and magnetic guiding loop (7) adopt interference fit, prevent leakage field.
5, apparatus surface is handled by traditional zinc-plated nickel plating that becomes, and reduces environmental pollution.
Claims (6)
