[0030] See also Figures 1 to 6 , the utility model provides a technical solution:

[0031] A cylinder head grinding device comprises a bottom plate 1 and a support frame 2, a movable screw module 3 is arranged at the bottom of the support frame 2, a movable end of the movable screw module 3 is fixedly connected to a top plate 4, four groups of electric push rods 5 are arranged on the top of the top plate 4, a mounting plate 6 is fixedly connected to the bottom of the electric push rods 5, a grinding processing mechanism 7 is arranged in the middle of the mounting plate 6, a cleaning mechanism 8 is arranged on one side of the mounting plate 6, and a cleaning mechanism 9 is arranged on the other side of the mounting plate 6;

[0032] The grinding processing mechanism 7 includes a servo motor 71, a turntable 72, a boss 73, a grinding block 74, a mounting frame 75 and a grinding milling cutter 76. The servo motor 71 is bolted to the top surface of the mounting plate 6, and the output end of the servo motor 71 extends to the bottom of the mounting plate 6. The turntable 72 is fixedly connected to the output end of the servo motor 71. Four bosses 73 are arranged on the side wall of the turntable 72 and are arranged at equal intervals. The grinding block 74 is bolted to the side wall of the boss 73. Four mounting frames 75 are fixedly connected to the side wall of the turntable 72. The grinding milling cutter 76 is bolted to the middle of the mounting frame 75.

[0033] Specifically, Figure 4As shown, the cleaning mechanism 9 includes a liquid storage tank 91, a liquid supply pump 92, a liquid outlet pipe 93 and a liquid outlet nozzle 94. The liquid storage tank 91 is arranged on the top of the mounting plate 6, the liquid supply pump 92 is bolted to the top of the mounting plate 6 and the input end is connected to the liquid storage tank 91, the liquid outlet pipe 93 is fixedly connected to the output end of the liquid supply pump 92, and a plurality of liquid outlet nozzles 94 are arranged on the side wall of the liquid outlet pipe 93, and the liquid outlet pipe 93 is located below the mounting plate 6.

[0034] Specifically, Figure 4 As shown, the end surface of the grinding milling cutter 76 is located below the end surface of the grinding sand block 74 .

[0035] Specifically, Figure 4 As shown, a limit ring 11 is bolted to the top surface of the turntable 72, a limit cover 12 is bolted to the bottom surface of the mounting plate 6, and the limit ring 11 is connected to the limit cover 12 by bearings.

[0036] Specifically, Figure 1 As shown, four threaded racks 13 are fixedly connected to the top surface of the base plate 1, an extrusion rod 14 is threadedly connected to the middle of the threaded rack 13, a positioning plate 15 is fixedly connected to the output end of the extrusion rod 14, and the middle of the four positioning plates 15 is arranged on the cylinder head body 16.

At this time, the servo motor 71 drives the turntable 72 to rotate, and the moving screw module 3 starts to drive the top plate 4 to move horizontally. In this process, the drive turntable 72 moves horizontally while rotating. At the same time, the liquid supply pump 92 supplies the cleaning liquid inside the liquid storage pump to the liquid outlet pipe 93, and then sprays it on the cylinder head body 16 through the liquid outlet nozzle 94, and then the grinding block 74 first contacts with the cylinder head body 16. The end face contacts and grinds the raised parts, stains, impurities, etc. on the surface of the cylinder head body 16. Then the grinding milling cutter 76 contacts the end face of the cylinder head body 16 for milling and grinding. At the same time, the end face of the grinding block 74 is higher than the end face of the grinding milling cutter 76 to prevent the cylinder head body 16 from contacting the grinding block 74 again after fine grinding. The bearing connection through the limit ring 11 and the limit cover 12 can improve the stability of the turntable 72.

[0040] Specifically, Figure 4 As shown, an electric heating wire 10 is arranged in the middle of the air outlet pipe 82, and the electric heating wire 10 is arranged in a spiral shape.

[0041] After the grinding sand block 74 and the grinding milling cutter 76 have polished the cylinder head body 16, the air pump 81 delivers high-pressure airflow in the air outlet pipe 82, and the high-pressure airflow is delivered to the end surface of the polished cylinder head body 16 through the air outlet pipe 82 and the air outlet head 83. The airflow can be heated by starting the electric heating wire 10, so that the debris and impurities on the end surface of the cylinder head body 16 can be blown off and cleaned, and the end surface of the cylinder head body 16 can be dried and cleaned.

[0042] By adopting the above technical solution, the problems of the existing cylinder head grinding device that the grinding of the cylinder head by means of the grinding block takes a long time and has low grinding accuracy, the cylinder head cannot be ground in a dual manner of rough grinding and fine grinding, and the debris generated after grinding cannot be cleaned.

[0043] Working principle: When the present application is in use, firstly, the positioning plate 15 is fixedly positioned on the cylinder head body 16 by rotating the extrusion rod 14, and the electric push rod 5 pushes the mounting plate 6 to move downward, and at the same time, the external power supply is connected to start the servo motor 71. At this time, the servo motor 71 drives the turntable 72 to rotate, and the moving screw module 3 starts to drive the top plate 4 to move laterally. In this process, the drive turntable 72 moves laterally while rotating, and at the same time, the liquid supply pump 92 supplies the cleaning liquid inside the liquid storage pump to the liquid outlet pipe 93, and then sprays it on the cylinder head body 16 through the liquid outlet nozzle 94, and then the grinding sand block 74 first contacts with the end face of the cylinder head body 16, and grinds the raised parts, stains, impurities, etc. on the surface of the cylinder head body 16, and then the grinding milling cutter 76 is used to grind the cylinder head body 16. The end surface of the cylinder head block 16 is contacted and milled and polished. At the same time, the end surface of the grinding block 74 is higher than the end surface of the grinding milling cutter 76, which can prevent the cylinder head block 16 from contacting the grinding block 74 again after fine grinding. After the grinding block 74 and the grinding milling cutter 76 have polished the cylinder head block 16, the air pump 81 delivers high-pressure airflow in the air outlet pipe 82, and the high-pressure airflow is delivered to the end surface of the polished cylinder head block 16 through the air outlet pipe 82 and the air outlet head 83. In this way, the cylinder head block 16 is subjected to a double polishing operation of rough polishing and fine polishing, which improves the polishing effect and efficiency of the cylinder head block 16, can blow off and clean the debris and impurities on the end surface of the cylinder head block 16, and can dry and clean the end surface of the cylinder head block 16.
