[0002] After the engine block and cylinder head are ground and precision ground, they still need to undergo finishing grinding to meet requirements. Currently, the finishing process still mainly relies on manual operation. Workers use hand-held grinding tools to repeatedly grind complex curved surfaces, cavity edges, and assembly contact surfaces, which presents the following problems: 1. High labor intensity; prolonged manual operation easily leads to fatigue and affects processing stability; 2. Poor precision and consistency; manual operation makes it difficult to ensure consistent dimensions and surface quality between different workpieces; 3. Low efficiency; manual finishing is slow and cannot meet the pace of mass production; 4. Safety and environmental hazards; dust, noise, and splashes generated during the grinding process pose a threat to worker health.

[0003] While some existing automated grinding equipment can perform rough grinding or localized grinding, it still falls short in terms of high-precision, multi-angle, and multi-station finishing processes, and cannot meet the high consistency and high precision process requirements of engine blocks and cylinder heads.

[0014] like Figures 1-3 As shown, an automatic precision finishing and grinding device for engine cylinder blocks and cylinder heads includes a closed safety chamber 1. Rectangular inlets and outlets are respectively opened in the middle of the left and right sides of the closed safety chamber 1. A conveyor roller 2 is arranged through the closed safety chamber 1 from left to right. The left side of the conveyor roller 2 extends to the outside of the inlet, and the right side extends to the outside of the outlet. A first precision finishing robot 3 on the left, a tool magazine 4 in the middle, and a second precision finishing robot 5 on the right are symmetrically arranged on the front and rear sides of the conveyor roller 2 inside the closed safety chamber 1. The first precision finishing robot 3 and the second precision finishing robot 5 are used for precision finishing and grinding of a first casting and a second casting, respectively. The first precision finishing robot 3 and the second precision finishing robot 5 both include a robot body 6. The end tool flange of the robot body 6 is connected to a grinding mechanism 7. A first vision recognition component 8 is arranged on the outside of the conveyor roller 2 near the inlet, and a second vision recognition component 9 is arranged on the outside of the closed safety chamber 1 near the outlet. A control cabinet 10, a pneumatic component 11, and a water cooling component 12 are arranged on the outside of the rear panel of the closed safety chamber 1.

[0015] In this embodiment, a first door 13 is provided on the rear panel of the enclosed safe room 1 near the left end, and a second door 14 is provided on the left side of the left side panel of the enclosed safe room 1 near the entrance. A first storage cabinet 15 is provided on the outer side of the rear panel of the enclosed safe room 1, and a second storage cabinet 16 is provided on the outer side of the left side panel of the enclosed safe room 1 near the rear end.

[0016] like Figure 4 As shown, a limiting mechanism 17 and a clamping mechanism 18 are respectively set on both sides of the conveyor roller 2 at the finishing and grinding stations of the first and second castings. The limiting mechanism 17 includes a fixed plate that is vertically fixed to the side of the conveyor roller 2, and the clamping mechanism 18 includes a movable plate that is vertically movable to the side of the conveyor roller 2. The movable plate is clamped by a cylinder. The grinding mechanism 7 includes a grinding machine body 71, and a grinding head 72 is provided at the output end of the grinding machine body 71.
