Abstract
The utility model relates to a motor shell front and rear plate edge clasping structure. The structure has changed the past traditional method that the front and rear plate of the shell was connected fixedly by nuts and screws, and applies the clasping structure to the edge of the motor shell front and rear plate so as to provide a material saving fastener; the front and rear plate of the motor shell can be fixedly assembled fast and easily; loose phenomenon will not be caused at the connection of the front and rear plate even the use time of motor is too long; the motor shell front and rear plate edge clasping structure is widely applicable to motor shell front and rear plate combination fastening structure.
Description
One, technical field
The utility model relates to the combination fastening structure that is applicable to the motor housing front and rear cover, and specifically buckle structure is drawn at motor housing front and rear cover edge.
Two, background technology
At present, the manufacturer of domestic all production micro-machines is after finishing chipwares such as the rotor of motor internal, stator and coil, when cover is gone up motor housing again, all taked to be connected the shell front and rear cover with nut with the fastening conventional method of screw then in the punching of shell front and rear cover edge.The obvious weak point of the method is: waste of material; Assemble time-consuming; The phenomenon that can occur nut loosening after service time is long again.
Three, summary of the invention
The technical scheme of the utility model technical issues that need to address and proposition is: a kind of fastener material that saves is provided, it is quick and easy to make up fastening motor housing front and rear cover, even motor uses the motor housing front and rear cover edge that loosening phenomenon can not take place yet in time long front and rear cover junction to draw buckle structure.
The technical scheme that buckle structure is drawn at the utility model motor housing front and rear cover edge is: it comprises motor housing front end housing (1), outer casing back lid (2), draw buckle structure (3), it is characterized in that the buckle structure (3) of drawing that shell front end housing (1) and outer casing back lid (2) tightens together is positioned at motor housing front and rear cover edge.Because the button of drawing in the buckle structure (3) of drawing is directly have drawn from shell front end housing (1) or outer casing back lid (2), so save the nut of traditional approach connection and the material of screw; Because drawing buckle structure (3) only needs its vertical application of force is got final product when fastening, and some buckle structures (3) of drawing of motor housing are all in the same plane, so can adopt the mode of hydraulic pressure simultaneously some buckle structures (3) of drawing to be carried out the application of force and the front and rear cover of fastening motor housing, therefore assemble the time and labour saving; Motor belongs to rigid deformation owing to draw the button of drawing of buckle structure (3) after repressed, so even the phenomenon that become flexible similar nut and screw junction can not occur yet after long-time the use.
Four, description of drawings
Fig. 1 draws the buckle structure outline drawing for the utility model motor housing front and rear cover edge.
Among the figure: 1, shell front end housing; 2, outer casing back lid; 3, draw buckle structure.
Fig. 1 illustrates:
The utility model is a kind of combination fastening structure of connecting small-sized motor housing front and rear cover of novelty, it Mainly be that some buckle structures 3 of drawing by being positioned at motor housing front and rear cover edge are the front end of motor housing Lid 1 and rear end cap 2 tighten together.
Five, embodiment:
At first, going out several holes in front end housing 1 edge of motor housing with punch press (can be square, different shapes such as rectangle), and go out setting that matches with front end housing 1 several holes and the some buttons of drawing that tilt slightly in motor housing rear end cap 2 edges, then the rotor of motor, in stator and the cavitys that chipware is packed into back end cover for motor 2 links to each other such as coil, again the cavity that links to each other with front end housing 1 is covered on the chipware of motor, some the drawing of front end housing 1 edge tipped in the hand-hole, at last this motor being drawn button lies in a horizontal plane on the hydraulic press work top up, somely draw fastening and be attached on front end housing 1 edge on the plane through what make rear end cap 2 after the vertical application of force of hydraulic press pressing plate, thereby the rear end cap 2 of motor housing is tightened together.
Claims (1)
1, buckle structure is drawn at motor housing front and rear cover edge, it comprises motor housing front end housing (1), outer casing back lid (2) is drawn buckle structure (3), it is characterized in that shell front end housing (1) and outer casing back are covered the buckle structure (3) of drawing that (2) tighten together is positioned at motor housing front and rear cover edge.
