Description

Motor rotor core laminates riveting tool
Technical field
The utility model is related to a kind of motor rotor core and laminates riveting tool.
Background technology
During existing motor rotor core riveting processing, rivet bar of the one end with manufactured head is substantially used, passes through top The rivet bar other end is squeezed out manufactured head by pin, so as to be riveted after the rotor core laminated is locked.This mode is needed Special-purpose rivet is bought, or rod iron one end is first processed into manufactured head, cost of manufacture is high, also low, the sometimes prefabricated riveting of efficiency The core stamping generation obscission that ailhead and the manufactured head squeezed out cause not of uniform size and causing rivet.
Utility model content
The technical problems to be solved in the utility model is:Overcome deficiency in the prior art can be simultaneously by riveting there is provided one kind The motor rotor core that nail rod two ends squeeze out manufactured head and lock rotor core laminates riveting tool.
The utility model solves the technical scheme that its technical problem used:A kind of motor rotor core laminates riveting work Dress, including top board, lower platen and the bottom plate set from top to bottom, top board is placed in under after rotor core stacking to be riveted Between pressing plate, bottom plate center is fixed with by being worn on lower platen and rotor core to the mandrel of top board, circumferential along rotor core At least three rivet bars for running through rotor iron core lamination are evenly equipped with, there is correspondence rivet bar upper end to extrude for described top board bottom surface The counterbore of upper manufactured head, lower platen is provided with the thimble that correspondence rivet bar lower end extrudes lower manufactured head.
Preferably, described rotor core is circumferentially evenly equipped with four rivet bars for running through rotor iron core lamination, top board It is correspondingly provided with correspondence on the counterbore that four diameters are more than rivet bar, lower platen and is fixed with the thimble that four diameters are more than rivet bar.
Further, fixed plate is provided between described bottom plate and lower platen, is provided between fixed plate and bottom plate after being pressurized It is counter to push the compression spring that pressing plate is moved up.
The beneficial effects of the utility model are:The utility model is locked by squeezing out manufactured head simultaneously to rivet bar two ends Tight rotor core, it is to avoid the big one end in manufactured head one end is easily produced during traditional operation small and cause what rotor punching came off to show As.Easy to operate simple, rivet bar materials are easy, without especially processing, are adapted to high-power major diameter motor stamping and laminate riveting The batch production of iron core.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
The thimble of 1. top board, 2. lower platen, 3. bottom plate, 4. rotor core, 5. mandrel, 6. rivet bar, 7. counterbore 8. in figure 9. the compression spring of fixed plate 10.
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of motor rotor core as shown in Figure 1 laminates riveting tool, including set from top to bottom top board 1, under Pressing plate 2 and bottom plate 3, are provided with fixed plate 9 between bottom plate 3 and lower platen 2, rotor core 4 to be riveted is placed in top board 1 after being laminated Between lower platen 2, the center of bottom plate 3 is fixed with mandrel 5, and mandrel 5 sequentially passes through fixed plate 9, lower platen 2 and rotor iron upwards After the endoporus that core 4 each has, it is slidably matched with the endoporus of top board 1.
Four rivet bars 6 for running through the punching of rotor core 4 are evenly equipped with along rotor core 4 is circumferential, rivet bar 6 passes through rotor Rivet hole in the punching of iron core 4 gets up the punching of rotor core 4 stacking, and the described bottom surface of top board 1 has correspondence rivet bar 6 Upper end extrudes four counterbores 7 of upper manufactured head, and lower platen 2 is provided with four tops that correspondence rivet bar 6 lower end extrudes lower manufactured head Pin 8, the diameter of counterbore 7 is fixed on bottom plate 3 than big 2mm of the diameter of rivet bar 6 or so, four bottoms of thimble 8, the thimble 8 On through stretching into the pin hole that lower platen 2 has after fixed plate 9, the diameter of thimble 8 is same than big 2mm of the diameter of rivet bar 6 or so.
Compression spring 10 provided with four elastic bearing lower platens 2 between described fixed plate 9 and bottom plate 3, in fixed plate 9 On the opposite face of bottom plate 3, circumferential four uniform cavitys are offered respectively, and described compression spring 10 is located in cavity.
In use, four rivet bars 6 without manufactured head are inserted in the rivet hole on rotor core 4, rotor core 4 is folded Required stacking factor is pressed onto, rotor core 4 is enclosed on mandrel 5, top board 1 is pressed in into the upper surface of rotor core 4, it is ensured that four rivetings The bottom of nail rod 6 is withstood on thimble 8, and upper end is placed in counterbore 7, when being pressed this frock from top to down with press, rivet bar 6 by Upper head starts manufactured head occur after to the pressure of top board 1, while the above-mentioned pressure rotor core 4 neat through laminating is transmitted To lower platen 2, lower platen 2 is compressed with four compression springs 10 and continues to move down, now the phase of thimble 8 at rivet bar 6 To independence, thimble 8 is moved up with respect to lower platen 2, produces upward riveting power to the bottom of rivet bar 6, rivet bar 6 by Under, upward pressure effect, so that the two ends of rivet bar 6 is squeezed out into manufactured head, rotor core 4 is locked and electric machine iron core is formed Component.
The utility model is by squeezing out manufactured head and locking rotor core 4 simultaneously to the two ends of rivet bar 6, it is to avoid tradition Easily produce that the big one end in manufactured head one end is small during operation and the phenomenon that causes rotor punching to come off.It is easy to operate simple, rivet bar 6 Materials are easy, without especially processing, are adapted to the batch production that high-power major diameter motor stamping laminates riveting iron core.
Above-mentioned embodiment is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with this skill The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this Enclose, all equivalent change or modifications made according to the utility model Spirit Essence should all cover in protection model of the present utility model In enclosing.
