Abstract
Abstract The invention relates to a snap spring structure for positioning magnetic steel, which belongs to the technical field of production and manufacturing of motors. The snap spring structure is in the long strip-shaped structure, the cross section of a snap spring comprises a transverse part, two first oblique parts are symmetrically obliquely formed at two ends of the transverse part by extending to the inner sides, and two second oblique parts are symmetrically obliquely formed at the end parts of the two first oblique parts by extending to the outer sides. The snap spring structure can facilitate the assembly of a housing with a front end cover and a rear end cover, effectively utilize space between the adjacent magnetic steel, be compact in structure, reduce the manufacturing cost of the motor and further solve the problems that a spacing interval between the adjacent magnetic steel is required to be larger in the prior art, otherwise, a screw can not penetrate from the middle of the snap spring, so that the volume of the housing is larger, the manufacturing cost of the motor is higher and the like. |5
Description
Description Snap Spring Structure for Positioning Magnetic Steel Technical Field The invention relates to a snap spring structure for positioning magnetic steel, which belongs to the technical field of production and manufacturing of motors. Background of the Invention Magnetic steel is often positioned in a housing of a motor through a snap spring between the adjacent magnetic steel, the magnetic steel is bonded on the inner wall of the housing through glue, and a front end cover and a rear end cover at two ends of the housing are connected with the housing together through screws penetrating the housing. The existing snap spring requires that a spacing interval between the adjacent magnetic steel needs to be larger, otherwise, the screw can not penetrate from the middle of the snap spring, so that the volume of the housing is larger, the manufacturing cost of the motor is higher and the like. Summary of the Invention The invention aims at providing a snap spring structure for positioning 1 magnetic steel, which can facilitate the assembly of a housing with a front end cover and a rear end cover, effectively utilize space between the adjacent magnetic steel, be compact in structure, reduce the manufacturing cost of a motor and further solve the problems that a spacing interval between the adjacent magnetic steel is required to be larger in the prior art, otherwise, a screw can not penetrate from the middle of the snap spring, so that the volume of the housing is larger, the manufacturing cost of the motor is higher and the like. The above technical purpose of the invention is mainly solved through the following technical scheme: the snap spring structure is in the long strip-shaped structure, the cross section of a snap spring comprises a transverse part, two first oblique parts are symmetrically obliquely formed at two ends of the transverse part by extending to the inner sides, and two second oblique parts are symmetrically obliquely formed at the end parts of the two first oblique parts by extending to the outer sides. After the magnetic steel is assembled through the snap spring, the snap spring of the invention can fully utilize the space between the adjacent magnetic steel, facilitate the penetration of the screw, further enable the structure of the motor to be more compact and reduce the manufacturing cost of the motor. Preferably, an included angle between each first oblique part and the transverse part is 50 degrees-70 degrees, thereby controlling the included angle between each oblique part and the transverse part within an appropriate 2 range and further enabling the screw to penetrate conveniently. Preferably, the included angle between each first oblique part and the second oblique part is 95 degrees-115 degrees. Preferably, the distance L between the joints of the two first oblique parts and the two second oblique parts is 2/5-4/5 of the length M of the transverse part. Therefore, the invention has the characteristics of facilitating the assembly of the housing with the front end cover and the rear end cover, effectively utilizing the space between the adjacent magnetic steel, being compact in structure, reducing the manufacturing cost of the motor and the like. Brief Description of the Drawings Figure 1 is a schematic diagram of structure of the invention with assembly of magnetic steel; Figure 2 is a schematic diagram of main view structure of the invention; Figure 3 is a schematic diagram of cross section structure of the invention. Detailed Description of the Invention In combination of the figures, the technical scheme of the invention is further specifically described through the following embodiment. Embodiment 1: as shown in Figure 2 and Figure 3, a snap spring I is in the long strip-shaped structure, the cross section of the snap spring I comprises a 3 transverse part 2, two first oblique parts 3 are symmetrically obliquely formed at two ends of the transverse part 2 by extending to the inner sides, an included angle P between each first oblique part 3 and the transverse part 2 is 63 degrees, two second oblique parts 4 are symmetrically obliquely formed at the end parts of the two first oblique parts 3 by extending to the outer sides, the included angle between each first oblique part 3 and the second oblique part 4 is 105 degrees, the distance L between the joints of the two first oblique parts and the two second oblique parts is 13mm, and the length M of the transverse part is 19mm. As shown in Figure 1, four blocks of magnetic steel 5 are uniformly distributed on the inner wall of a housing 6, the magnetic steel 5 is bonded and fixed with the housing 6 through glue, the snap spring is arranged between the adjacent magnetic steel 5, the end parts of the magnetic steel 5 in the circumferential direction are matched between the first oblique parts 3 and the second oblique parts 4 of the snap spring 1, the screw can conveniently pass through a region surrounded by the two first oblique parts 3 and the transverse part 2 of the snap spring 1, thereby fully utilizing the space between the adjacent magnetic steel. 4
