Abstract
The utility model discloses a novel sewing machine motor flat plate shaft. The novel sewing machine motor flat plate shaft comprises a rotating shaft. A flat plate is installed on the rotating shaft. Rotating locking faces are arranged on the side wall of an end portion on which the rotating shaft and the flat plate are connected. The flat plate is provided with a shaft sleeve and a shaft hole. An inner hole of the shaft sleeve and the end portions, on which the rotating locking faces are arranged, of the rotating shaft and a shaft hole are matched in shape. The rotating shaft penetrates through the shaft sleeve and the shaft hole and is fixed with the flat plate in a welding mode. The rotating locking faces are arranged on the rotating shaft, meanwhile, the shaft sleeve and the shaft hole on the flat plate are matched with the rotating locking faces, the rotating shaft is matched with the flat plate, then transmission of force can be conducted by contacting among the rotating locking faces and the shaft sleeve and the shaft hole, and transmission of high torque between the rotating shaft and the flat plate can be achieved without welding, after the rotating shaft and the flat plate are welded, positions of the rotating shaft and the flat plate can be fixed, and a maximum torque capable of being supported can be further improved. The novel sewing machine motor flat plate shaft effectively reduces stressing of welding parts in the prior art, greatly improves connecting reliability between the rotating shaft and the flat plate, and service life of the novel sewing machine motor flat plate shaft is prolonged .
Description
Technical field
The utility model relates to a kind of component of electrical motor of sewing machine, especially a kind of panel axes of electrical motor of sewing machine.
Background technique
Sewing machine work connects clutch by electrical motor of sewing machine and drives miscellaneous part realization work and shutdown again, and wherein comparatively crucial parts are panel axes in the clutch, connects clutch-plate on the panel axes and comes the clutch function.Panel axes is rotating shaft to be fixed on dull and stereotyped going up realize; existing technology is the circular hole of a band of punching press flange on flat board; fix with the flat board welding after then circular rotating shaft being inserted circular hole; because panel axes needs moment to start or shuts down, therefore produce huge impact in the clutch working procedure.Rotating shaft is by welding with dull and stereotyped fixing fully, and the welding part is easy to generate big stress and fault in material, is easy to cause in the welding part fracture inefficacy of whole clutch.
Summary of the invention
The purpose of this utility model provides a kind of novel sewing machine motor panel axes, has improved the linkage structure between rotating shaft and the flat board, reduces the stressed of welding part, prolongs the working life of panel axes.
The utility model is to realize above-mentioned purpose like this:
Novel sewing machine motor panel axes, comprise rotating shaft, flat board is installed in the rotating shaft, described rotating shaft is provided with the twist-lock face with the sidewall of the dull and stereotyped end that is connected, described flat board is provided with axle sleeve and axis hole, the end shape that is provided with the twist-lock face in the endoporus of axle sleeve and axis hole and the rotating shaft adapts, and rotating shaft is fixed with the flat board welding after passing axle sleeve and axis hole.
Wherein, described twist-lock face is two, is symmetricly set in roller end.
Wherein, described flat board comprises dull and stereotyped main body, is provided with foliated hollow out in the middle of the dull and stereotyped main body, has to interlace with the corresponding foliated connecting plate of foliated hollow out shape and hollow out position and be connected with dull and stereotyped main body by screw; Axle sleeve and axis hole are arranged on the foliated connecting plate.
Wherein, the blade quantity of described foliated hollow out and foliated connecting plate is three or four.
The beneficial effects of the utility model are: the twist-lock face is set in rotating shaft, simultaneously axle sleeve on the flat board and axis hole are all adapted with it, so after rotating shaft and dull and stereotyped the cooperation, the transmission of power can be undertaken by contacting between twist-lock face and axle sleeve and the axis hole, even do not weld, just can realize the transmission of big moment between rotating shaft and the flat board, both positions can be fixed after the welding can also further improve simultaneously the maximum moment that can bear.This structure can effectively reduce the stressed of welding part in the prior art, has improved the connection reliability between rotating shaft and the flat board greatly, prolongs the working life of panel axes.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a plan view;
Fig. 2 is an A-A cross section view among Fig. 1.
Embodiment
With reference to Fig. 1 and Fig. 2, novel sewing machine motor panel axes, comprise rotating shaft 1, be equipped with dull and stereotyped 2 in the rotating shaft 1, described rotating shaft 1 is provided with twist-lock face 3 with the sidewall of dull and stereotyped 2 ends that are connected, described dull and stereotyped 2 are provided with axle sleeve 4 and axis hole 5, and the end shape that is provided with twist-lock face 3 in the endoporus of axle sleeve 4 and axis hole 5 and the rotating shaft 1 adapts, and axle sleeve 4 is passed in rotating shaft 1 and axis hole 5 backs are fixed with dull and stereotyped 2 welding.Twist-lock face 3 is set in rotating shaft 1, simultaneously axle sleeve 4 and axis hole 5 on the flat board 2 are all adapted with it, rotating shaft 1 is with after dull and stereotyped 2 cooperate so, the transmission of power can be undertaken by contacting between twist-lock face 3 and axle sleeve 4 and the axis hole 5, even do not weld, just can realize the transmission of high pulling torque between the rotating shaft 1 and dull and stereotyped 2, both positions can be fixed after the welding while can also further improve the maximum moment that can bear.This structure can effectively reduce the stressed of welding part in the prior art, has improved the connection reliability between rotating shaft 1 and dull and stereotyped 2 greatly, prolongs the working life of panel axes.
Can bear bigger moment of torsion for further improving being connected between the rotating shaft 1 and dull and stereotyped 2, described twist-lock face 3 is two, is symmetricly set in rotating shaft 1 end.Twist-lock face 3 more than three can also be set certainly, but because axle sleeve 4 and axis hole 5 are by stamping forming, if adopt more than three, cause dull and stereotyped 2 punch-out defective to occur on the contrary easily owing to deformation quantity is excessive, make the punching press position be easy to generate fracture.
For further improving the structure of flat board 2 to bear bigger moment of torsion, described dull and stereotyped 2 comprise dull and stereotyped main body 21, be provided with foliated hollow out 22 in the middle of the dull and stereotyped main body 21, have to misplace mutually with hollow out 22 positions with the corresponding foliated connecting plate 23 of foliated hollow out 22 shapes and be connected with dull and stereotyped main body 21 by screw; Axle sleeve 4 and axis hole 5 are arranged on the foliated connecting plate 23.The blade quantity of foliated hollow out 22 and foliated connecting plate 23 is three or four.
