Abstract
The invention discloses a three column preloading type rotor core shaft-insertion device, which comprises a frame. A hydraulic press is arranged on the frame. The tail end of the piston rod of the hydraulic press is provided with a pressure head. The bottom of the frame is provided with a workbench. A lower die is fixed on the workbench. The center of the lower die is provided with a die hole. An upper die matched with the lower die is arranged on the lower die. The frame is provided with two small hydraulic presses distributed symmetrically on the two sides of the hydraulic press. The tail ends of the piston rods of the two small hydraulic presses are fixedly connected with the upper end surface of the upper die. The center of the upper die is provided with a through hole. Due to the adoption of the above technical scheme of the invention, the edge of the upper end surface of a rotor iron core is compressed by the two small hydraulic presses via the upper die. After that, a shaft is inserted into the shaft hole of the rotor iron core by the hydraulic press. The end surfaces of products, laminated by the three column preloading type rotor core shaft-insertion device, are flat. Meanwhile, the sheet and the shaft of the iron core are combined more firmly. The device is simple in structure and the yield of rotors is improved.
Description
Technical field
The present invention relates to motor device technical field, particularly a kind of three post prepressing type rotor cores enter shaft device.
Background technology
At present, motor is when assembling, first axle is needed to load in rotor core, axial compression enters in rotor iron filings by direct after rotor core is fixing by existing general expression shaft press, but due to when being pressed into axle, the discontinuity of rotor core, causes the rotor core two ends dough sheet extruded to stick up, out-of-flatness.
Summary of the invention
It is simple that object of the present invention is just to provide a kind of structure, and three post prepressing type rotor cores of the rate of finished products that can improve rotor enter shaft device.
The object of the invention is by such technical scheme realize: a kind of three post prepressing type rotor cores enter shaft device, comprise frame, frame is provided with hydraulic press, the piston-rod end of hydraulic press is provided with the pressure head for armature spindle being pressed into rotor core, workbench is provided with bottom described frame, described workbench is fixed with counterdie, counterdie center is provided with the nib for fixed rotor iron core, counterdie is provided with the patrix matched with it, described frame is also provided with two the little hydraulic presses being symmetrically distributed in hydraulic press both sides, the end of piston rod of described two little hydraulic presses is fixedly connected with the upper surface of patrix, patrix center is provided with the through hole passed for armature spindle.
Further, the degree of depth of the nib at described counterdie center is equal with the height of rotor core.
Further, the distal center of described pressure head is provided with the counterbore matched with armature spindle.
Owing to have employed technique scheme, the present invention has following advantage:
Three post prepressing type rotor cores of the present invention enter shaft device, first compressed the edge, upper surface of rotor core by patrix with two little hydraulic presses, by hydraulic press, axial compression is entered in the axis hole of rotor core again, it is smooth for entering with three pillar type prepressing type iron core the product end surface that axle machine laminates out, and it is more fastening between lamination and axle, structure is simple, and can improve the rate of finished products of rotor.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized by specification below and claims and be obtained.
