Embodiment

As shown in Figures 1 to 4, a kind of easily assembly flange disk, can improve ring flange and automotive hub and race ring etc. The compactness coordinated between assembly parts, connect them more stable, it is more secure when used more reliable, and due to the bearing of cooperation Coil structures are fairly simple, therefore assembling is more prone to.By multiple sealed steps, fitted seal circle can make when in use simultaneously Coordinate between part even closer.Part is integrally formed entirely through the mode of die casting, has higher machining accuracy, It can ensure that connection is more stable during connection, automobile is operationally safer, and part cost in production is lower, and efficiency is more It is high.It includes cylindrical base 1 made of metal material, and the thickness of described matrix 1 is 13.3mm, overall to use die casting Mode be integrally formed, can make part that there is more preferable intensity when in use, enhance part connection when stability, make it Using effect it is more preferable.It is sequentially provided with and is integrally formed and concentric cylinder first centered on the axle center of described matrix 1 Step 2, the step 4 of second step 3 and the 3rd, the diameter of three structures are reduced successively, and the height of the first step 2 is 8.6mm, the height of the second step 3 is 21.5mm, and the height of the 3rd step 4 is 33.3mm, provided with different height Step can make this part more convenient in assembling process, and the compactness assembled is more preferable, after the completion of assembling when in use Performance is more preferable.The fillet that radius is 5mm, the He of the 3rd step 4 are provided between the first step 2 and the second step 3 The fillet that radius is 3mm is provided between the second step 3, cylinder the is provided between described matrix 1 and the first step 2 One sealed step 10, the fillet that radius is 5mm, different positions are provided between first sealed step 10 and the first step 2 The fillet put, which is set, can make compactness during assembling more secure, and function is more stable during operation.First sealed step 10 With the first step 2 be concentric structure and diameter is more than the first step 2, and in assembling, the first sealed step 10 is with matching somebody with somebody Seal groove on the part of conjunction is combined together, and makes the compactness between two parts stronger.The centre bit of 3rd step 4 Installing taper first and assembled endoporus 5, the depth of the first assembling endoporus 5 is the half of the height of the 3rd step 4, according to The demand of mating parts is come the design that carries out, it is ensured that it can mating parts use, so as to which it be applied on automobile, make automobile Better performance can be played.The reverse side of described matrix 1 is provided with cylindrical second assembles post 6, the axle center of described matrix 1 and described the On the same line, the stress of part just can more be stablized than more uniform, during use after assembling in the axle center of two assembles posts 6.Institute The height for stating the second assembles post 6 is 2 times of the thickness of described matrix 1, and by test optimization, so may insure part uses the longevity Life reaches optimal.The center of second assembles post 6 is provided with the second assembling endoporus 8, the bottom of the second assembling endoporus 8 Center is provided with taper assembling bottom outlet 9, the depth of the assembling bottom outlet 9 and the deep equality of the described second assembling endoporus 8, this Several pilot holes are provided to match the part of cooperation and design, and have special requirement, it is impossible to arbitrarily design, otherwise Normal use will be unable to.The taper of the assembling bottom outlet 9 is identical with the taper of the described first assembling endoporus 5, first assembling The taper of endoporus 5 is also identical with the taper of the described second assembling endoporus 8, will be tight if the taper design of these positions is unreasonable Ghost image rings the performance that it links together with automobile, can substantially reduce safety and stability when in use.Described Cylindrical second sealed step 7 is provided between two assembles posts 6 and described matrix 1, fitted seal circle uses in assembling, can be true It is even closer to protect part connection, it is more preferable to assemble effect.The diameter of second sealed step 7 is more than second assembles post 6 Diameter, the height of second sealed step 7 are a quarters of the height of the second assembles post 6, the second assembling endoporus 8 Depth it is identical with the height of second assembles post 6, it is described second assembling endoporus 8 base diameter be more than the assembling bottom outlet 9 opening diameter, the cooperation that part can be even closer in assembling is on the one hand may insure, cooperates between part and more flows Freely, the effect of each part can be preferably played when in use；On the other hand it may also be ensured that part structure in shaping is more steady Fixed, production is more convenient, makes the part qualification rate produced higher.

Preferably, described matrix 1 is made up of aluminum alloy materials, and the diameter of second sealed step 7 with it is described The diameter of first step 2 is equal, and when producing in enormous quantities, cost is lower, and quality is lighter, using more convenient.

Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art For personnel, on the premise of principle described in the utility model is not departed from, some improvement or replacement can also be made, these improvement Or replace and also should be regarded as the scope of protection of the utility model.
