Description

Technical Field

[0001] The invention relates to the technical field of cast aluminum rotor press-assembly, and in particular to a cast aluminum rotor press-assembly device for motor production. Background Art

[0002] Cast aluminum rotors are common rotors in motors. Aluminum or aluminum alloy materials are embedded into the motor core through a die-casting process, acting as the power transmission core. Aluminum is filled inside to form metal guide bars, replacing the traditional motor rotor winding structure.

[0003] The existing invention patent with patent publication number CN112427924B discloses a cast aluminum rotor press-fitting device for motor production. Specifically, the device places a rotating shaft at the upper end of the center of the cast aluminum rotor through the setting of a guide member. Then, through the guide motor, the guide screw drives two guide clamps to move in relative directions, so that the rotating guide rods on the two guide clamps contact the outer peripheral surface of the rotating shaft. The rotating shaft and the cast aluminum rotor are then assembled through a hydraulic mechanism.

[0004] However, this invention patent still has the following problems: the rotating shaft needs to be placed between the two guide clamps when being fixed, and the rotating shaft can not be released until the two guide clamps clamp and fix the rotating shaft. Therefore, the rotating shaft needs to maintain a vertical posture when being placed, and be located between the two guide clamps. In the process of fixing the rotating shaft by the two guide clamps, it is also necessary to continuously adjust to ensure that the rotating shaft is clamped vertically between the two guide clamps and is located on the top of the hourglass-shaped guide rotating rod. The above operation steps are cumbersome, and the accuracy of the placement of the rotating shaft needs to be ensured, which is inefficient and it is difficult to ensure the accuracy of the relative position of the rotating shaft and the cast aluminum rotor.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 6 As shown, the present invention provides a cast aluminum rotor pressing device for motor production, comprising a base 1, a rotating device 2 and a support plate 5 are provided on the base 1, a disc 3 is provided on the top of the rotating device 2, and a plurality of fixing devices 4 for fixing the cast aluminum rotor are evenly provided on the disc 3 around the center of the disc 3, a lifting and pressing device 6 and a moving mechanism 7 are provided on one side of the support plate 5, a fixing seat 8 is provided on the moving mechanism 7, a funnel-shaped supporting cylinder 9 is provided on the fixing seat 8, a centering structure 10 is provided on the top of the supporting cylinder 9, a temporary limiting structure 11 for supporting and fixing the rotating shaft is provided at the bottom of the inner side wall of the supporting cylinder 9, and the part of the temporary limiting structure 11 that supports the rotating shaft can slide along the direction of the rotating shaft pressing and undergo elastic deformation.

[0030] Among them, the supporting cylinder 9 is used to place the rotating shaft, the centering structure 10 is used to push the rotating shaft from the circumferential side of the rotating shaft to stand upright at the center of the supporting cylinder 9, and fix the rotating shaft, and the rotating shaft can move on the centering structure 10 in the vertical direction. The temporary limiting structure 11 releases the load restriction on the rotating shaft when the rotating shaft drops to a preset height, and the lifting and pressing device 6 is used to press down the rotating shaft and assemble it with the cast aluminum rotor.

[0031] The supporting tube 9 includes a first annular plate 901 and a positioning tube 902. The first annular plate 901 is arranged on one side of the fixed seat 8. The bottom of the first annular plate 901 is connected to an inclined second annular plate 903, and the positioning tube 902 is concentrically arranged at the bottom of the second annular plate 903.

[0032] When the present application is in use, the cast aluminum rotor is placed on one of the fixing devices 4 for fixation, and the rotating shaft is placed in the supporting cylinder 9. The rotating shaft is squeezed to the center of the supporting cylinder 9 through the centering structure 10 and is fixed in the supporting cylinder 9. The bottom of the rotating shaft is against the temporary limiting structure 11. At the same time, the temporary limiting structure 11 also fixes the rotating shaft, further ensuring the stability of the rotating shaft during the descent process and preventing the rotating shaft from deviating from its position during the descent process.

[0033] The moving mechanism 7 moves the fixed seat 8, so that the supporting cylinder 9 moves to the preset position, and then the rotating device 2 drives the disc 3 to rotate, so that the cast aluminum rotor rotates to the bottom of the supporting cylinder 9. At this time, the lifting and pressing device 6 presses the rotating shaft downward, so that the rotating shaft squeezes the temporary limiting structure 11 to move downward and undergoes elastic deformation. When the rotating shaft drops to the lowest point where the temporary limiting structure 11 can drop, the temporary limiting structure 11 releases the load and restriction on the rotating shaft, so that the rotating shaft moves into the cast aluminum rotor under the downward pressure of the lifting and pressing device 6 to complete the pressing.

[0034] The centering structure 10 automatically fixes the rotating shaft to the center of the supporting cylinder 9 to align with the cast aluminum rotor directly below the supporting cylinder 9, avoiding multiple adjustments to the posture of the rotating shaft and improving the pressing efficiency. The temporary limiting structure 11 supports the rotating shaft from the bottom of the rotating shaft, ensuring the stability of the rotating shaft during the pile driving process.

[0035] In this embodiment, the rotating device 2, the fixing device 4, the lifting and pressing device 6 and the moving mechanism 7 are all existing technologies. For example, the rotating device 2 is a motor or a motor driving two meshing gears to drive the disc 3 to rotate. The fixing device 4 is a motor or a manual screw drive to rotate. The two fixing plates on the screw move toward each other to clamp and fix the cast aluminum rotor. The lifting and pressing device 6 is a lifting device such as a hydraulic push rod or an electric push rod to push the pressing plate up and down, or a fixed clamping member in a cast aluminum rotor pressing device for motor production disclosed in the invention patent with reference to patent announcement number CN112427924B. The moving mechanism 7 is a motor driving the screw to drive the fixed seat 8 to move. The above are all existing technologies, and the technical principles will not be elaborated on here.

[0036] When the rotating shaft is placed in the supporting tube 9, the rotating shaft is first placed obliquely in the first annular plate 901, and the bottom of the rotating shaft contacts the upper surface of the second annular plate 903. When the centering structure 10 squeezes the rotating shaft until the rotating shaft stands up and is concentric with the positioning tube 902, the bottom of the rotating shaft falls into the positioning tube 902 and contacts the temporary limiting structure 11, and then the temporary limiting structure 11 fixes the rotating shaft.

[0037] The centering structure 10 includes two mounting plates 101 symmetrically arranged on the outer wall of the first annular plate 901, each mounting plate 101 is provided with a first telescopic device 102, and the movable ends of the two first telescopic devices 102 have opposite movable directions, and each movable end of the first telescopic device 102 is provided with a connecting seat 103, each connecting seat 103 is rotatably connected to two centering pressure plates 104 through a torsion spring, and each centering pressure plate 104 is provided with a plurality of avoidance grooves 105 in the vertical direction, and the avoidance grooves 105 on the two adjacent centering pressure plates 104 located on the two connecting seats 103 are staggered, and each connecting seat 103 is symmetrically provided with two limiting strips 106, and the limiting strips 106 are used to limit the maximum rotation angle of the centering pressure plate 104.

[0038] Each centering pressure plate 104 is provided with a plurality of balls.

[0039] When the rotating shaft is placed in the supporting cylinder 9, the rotating shaft rests on one of the centering pressure plates 104, the two first telescopic devices 102 are started at the same time, and the four centering pressure plates 104 on the two connecting seats 103 move toward each other. Since the avoidance grooves 105 opened on the centering pressure plates 104 located on different connecting seats 103 are staggered, the centering pressure plates 104 on the two connecting seats 103 can move crosswise with each other, and the rotating shaft gradually stands up under the extrusion of the multiple centering pressure plates 104 moving toward each other, until the multiple centering pressure plates 104 simultaneously abut against the side walls of the rotating shaft. At this time, the rotating shaft is in an upright state and is concentric with the positioning tube 902.

[0040] During the process of the rotating shaft standing upright, the bottom of the rotating shaft will generally slide from the second annular plate 903 to the top of the positioning tube 902. After the rotating shaft stands upright, it may slide downward along the positioning tube 902 for a distance, or the rotating shaft may be pressed down by the lifting and pressing device 6 to make the rotating shaft slide downward along the positioning tube 902 for a distance. The downward movement of the rotating shaft is restricted by the temporary limiting structure 11, and then the rotating shaft is fixed by multiple centering pressure plates 104.

[0041] The centering plate 104 is limited to a maximum rotation angle by a limiting strip 106 to ensure stable fixation of the rotating shaft.

[0042] The arrangement of the balls enables the shaft to move downward when pressure is applied, thus reducing friction damage.

[0043] The temporary limiting structure 11 includes a support 111 symmetrically arranged on the outer wall of the positioning tube 902, each support 111 is provided with two telescopic structures 112 with opposite movement directions, each telescopic structure 112 is slidably connected with an extrusion bearing structure 113 for supporting and fixing the rotating shaft, each support 111 is provided with an adjustment groove 114 in the vertical direction, each adjustment groove 114 is provided with an elastic adjustment member 115 that can move up and down, and each extrusion bearing structure 113 is slidably connected to the corresponding elastic adjustment member 115, and two through grooves 116 are provided on the outer wall of the positioning tube 902, which are respectively connected to the two adjustment grooves 114.

[0044] When the rotating shaft moves downward along the positioning tube 902 until it contacts the extruded bearing structure 113, the extruded bearing structure 113 fixes the rotating shaft, and then the lifting and pressing device 6 presses down the top of the rotating shaft, so that the rotating shaft drives the extruded bearing structure 113 to slide downward along the telescopic structure 112, and squeezes the elastic adjustment member 115 to move downward, so that the bottom of the rotating shaft gradually approaches the cast aluminum rotor. When the elastic adjustment member 115 drops to the lowest point, the telescopic structure 112 drives the extruded bearing structure 113 to move in the direction away from the positioning tube 902, so that the rotating shaft can continue to descend along the positioning tube 902 and be pressed into the cast aluminum rotor.

[0045] When the next press-fitting is performed, the elastic adjusting member 115 automatically returns to its original position under the action of the elastic force, and the extrusion bearing structure 113 is driven to return to its original position through the telescopic structure 112 .

[0046] The telescopic structure 112 includes a second telescopic device 117 disposed on the support 111 . A connecting plate 118 is disposed at the end of the second telescopic device 117 , and the extrusion bearing structure 113 is slidably disposed on the connecting plate 118 .

[0047] The second telescopic device 117 drives the connecting plate 118 away from or close to the positioning tube 902 to control the extrusion bearing structure 113 to move away from or close to the positioning tube 902, thereby releasing the restriction on the bottom of the rotating shaft or restricting the descent of the rotating shaft.

[0048] The extrusion bearing structure 113 slides up and down along the connecting plate 118 .

[0049] The extrusion bearing structure 113 includes a bearing plate 119 slidably connected to the connecting plate 118, and a fixed pressure plate 120 is provided on the bearing plate 119, and the width of the fixed pressure plate 120 is smaller than the width of the through groove 116 and the adjustment groove 114. The fixed pressure plate 120 includes two plate bodies fixed on the bearing plate 119, and the two plate bodies are connected on one side, and the angle formed by the two plate bodies is less than 90°.

[0050] The rotating shaft is jointly supported by two supporting plates 119. When the two supporting plates 119 move toward the center of the positioning tube 902 respectively through the two second telescopic devices 117, the two fixed pressure plates 120 move synchronously until the two fixed pressure plates 120 are against the outer wall of the rotating shaft. At this time, the rotating shaft is fixed and the downward movement of the rotating shaft is limited by the elastic force of the elastic adjustment member 115.

[0051] The fixed pressure plate 120 forms a V shape through two plates, which can better fix the rotating shaft.

[0052] When the bearing plate 119 releases the restriction on the bottom of the rotating shaft, the bearing plate 119 and the fixed pressure plate 120 can both pass through the through slot 116 and the adjustment slot 114 to avoid interference with the movement of the rotating shaft.

[0053] The elastic adjustment member 115 includes two springs 121 symmetrically arranged on the inner wall of the adjustment groove 114. A sliding groove 122 is provided on the two opposite side walls of the adjustment groove 114, and the two sliding grooves 122 are used to respectively install the sliding grooves 122 of the two springs 121. A sliding seat 123 is slidably connected in the two sliding grooves 122, and each spring 121 is connected to the sliding seat 123. The supporting plate 119 is slidably connected to the sliding seat 123.

[0054] When the supporting plate 119 is subjected to pressure from the rotating shaft, the slide 123 moves downward along the slide groove 122 under the pressure of the supporting plate 119, and at the same time, multiple springs 121 are stretched until the slide 123 moves to the lowest point of the slide groove 122, and then the second telescopic device 117 drives the supporting plate 119 to slide along the top of the slide 123 to the outside of the positioning tube 902.

[0055] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
