Embodiment 1
[0042] A kind of engine block processing technology, its steps are as follows:
[0043] 1) The cylinder blank casting is produced by casting method; the cylinder blank casting includes a cylindrical structure processing part 1 and a cylindrical positioning part 2 coaxially arranged with the processing part, and the outer diameter of the positioning part is larger than the processing part The outer diameter of the positioning part is 2-6cm in height;
[0044] 2) Positioning holes 3 are respectively drilled on the bottom and side wall of the positioning part of the cylinder blank casting, and the positioning part is clamped and fixed on the fixture. one side is the top side;
[0045] 3) Rough machining
[0046] ①Finish milling on the left side, processing the cylinder hole and sand hole;
[0047] ②Finish milling of the top surface, rough boring of the cylinder hole, and machining of the top surface bolt holes;
[0048] ③Finish milling of both end faces, rough milling of cams...
Embodiment 2
[0061] As a further optimization to Embodiment 1, in step 1), the cylinder block blank casting comprises the following components:
[0062] Si+Fe 22.5%, Cu 0.28%, Mn 0.06%, Mg 1.6%, Cr 0.07%, Zn 0.16%, Ti0.005%, Ni 0.5%, and the balance of Al and unavoidable impurities.
[0063] Further, in the composition of the cylinder blank casting, Si / Fe=32.
[0064] Further, the preparation method of the cylinder blank casting is: adding the raw materials into the melting furnace for melting, casting and extruding to obtain the casting, and then heat-treating the casting; the heat treatment method is: 220°C for 25 minutes, 390°C for 25 minutes, Keep warm at 420°C for 20 minutes and 260°C for 30 minutes, then cool to room temperature and let stand for 60 minutes.
[0065] Further, during the rough machining of step 2) and the finishing process of step 3), it is necessary to spray cutting fluid to the casting; the preparation method of the cutting fluid is: 1.8% of simethicone oil, 6.5% o...
Embodiment 3
[0067]As a further improvement to Embodiment 1 and Embodiment 2, the jig used to process the engine block includes a base 4 on which a rotary oil cylinder 5 is provided, and an operating platform 6 is arranged on the rotary oil cylinder. A plurality of hydraulic cylinders 7 are evenly distributed, and the direction of the push rod of the hydraulic cylinder is set towards the center of the circle. The push rod of the hydraulic cylinder is provided with a fixed terminal 8, and the first crimping terminal 9 and the second crimping terminal 10 are replaceable on the fixed terminal ;
[0068] The first crimping terminal is used to fix the positioning part of the cylinder body blank casting, and the second crimping terminal is used to fix the processed part of the cylinder body blank casting.
[0069] Further, the first crimping terminal includes a first support plate 11, which is detachably fixed on the fixed terminal through fasteners, a first positioning plug 12 is arranged on th...
