technical field [0001] The invention relates to the field of grinding devices for ceramic aluminum alloy piston rings, in particular to the field of synchronous grinding devices for inner and outer diameter surfaces of piston rings. Background technique [0002] As we all know, nano-ceramic aluminum alloy is light in weight, and has the characteristics of high rigidity, high strength, fatigue resistance, low expansion, high damping, high temperature resistance, etc. Integrating nano-ceramic aluminum alloy materials into the manufacture of automobile pistons is a current piston manufacturing process. trend, we use ceramic aluminum alloy pistons made of nano-ceramic aluminum alloy materials (such as figure 1 Shown) has the advantages of high strength, high wear resistance and high temperature resistance, it is assembled into the cross section of the piston and its corresponding annular groove, relying on the pressure difference of gas or liquid in the outer circle of the ring ...

AI Technical Summary

Problems solved by technology

[0003] The ceramic aluminum alloy piston ring needs to be ground after the casting fracture (end gap), but now in production, it is often ground and produced by a grinding wheel, but it can only be ground on one side, which makes the efficiency of the grinding machine low , at the same time, due to the high strength of the ceramic aluminum alloy piston ring, it is time-consuming to polish it. In order to solve this problem, the prior art (for example, Chinese Patent No. 202010536723.9) discloses a piston ring grinder, through The first grinding device and the second grinding device are installed on the top, which enhances the grinding efficiency in production and speeds up the production speed. By adjusting the position of the slide plate in the groove, the diameter of the piston ring to be polished that this device is suitable for can be adjusted perfectly. Piston rings of various diameters are added, which increases the versatility of the grinding machine and realizes synchronous grinding of the inner and outer diameter surfaces of the piston rings, but it has some defects. First, the existing piston rings are easy to install on the piston. , it is necessary to open a piston ring end gap on the surface of the piston ring (such as figure 1 As shown), the existing piston ring grinding operation is after the fracture (end gap) operation, because the ceramic aluminum alloy piston ring has high toughness, and the piston ring after the fracture (end gap) operation is on the top of the two guide rollers Due to the existence of the fracture (end gap), the piston ring is prone to deviation, which affects the grinding quality. Secondly, it is impossible to grind the fracture (end gap) on the ceramic aluminum alloy piston ring with the existing equipment, so there is a certain use Therefore, we propose a synchronous grinding device for the inner and outer diameters of piston rings
