[0021] Example
[0022] Reference Figure 1-3 An automated CNC grinding machine for high-precision mold processing includes a base 1 and a robotic arm 8. A main electric rotary table 3 is fixedly installed on the base 1 so that the main electric rotary table 3 drives each fixture to carry the mold to be processed to move below the robotic arm 8. Several fixtures are evenly fixedly installed at the output end of the main electric rotary table 3 so that the mold to be processed can be fixed by the fixtures to ensure the stability of the mold processing process and thus improve the processing accuracy. The robotic arm 8 is fixedly installed on one side above the base 1 by a bracket 2. A grinder is fixedly installed at the execution end of the robotic arm 8 so that the robotic arm 8 drives the grinder to perform multi-directional grinding on the mold on the fixture.
[0023] Robotic arm 8 uses existing technologies, such as the KUKA six-axis robotic arm;
[0024] In this embodiment, the grinder includes a motor 9, a liquid supply pipe 10, a grinding wheel 11, a pipe seat 12, and a liquid outlet pipe 13. The motor 9 is fixedly connected to the execution end of the robotic arm 8. The grinding wheel 11 is fixedly installed at the output end of the motor 9 so that the grinding wheel 11 can be driven to rotate by the motor 9, thereby grinding the surface of the mold. A cooling chamber 14 is coaxially provided on the housing of the motor 9. A pipe seat 12 is fixedly installed on one side of the motor 9. The pipe seat 12 is fixedly connected to one end of the liquid supply pipe 10. The liquid outlet pipe 13 is fixedly installed on the side of the motor 9 facing the grinding wheel 11. Both the liquid outlet pipe 13 and the pipe seat 12 are connected to the cooling chamber 14. In use, the liquid supply pipe 10 is connected to the grinding fluid supply equipment so that the liquid supply pipe 10 can deliver the grinding fluid to the cooling chamber 14 through the pipe seat 12, and then discharge it from the liquid outlet pipe 13 to the grinding wheel 11. In this way, not only can the motor 9 be cooled, but the normal use of the grinding fluid will not be affected.
[0025] In this embodiment, a grinding fluid collection chamber 7 is coaxially provided on the base 1 to collect the grinding fluid discharged from the outlet pipe 13. A drain valve is provided on one side of the lower outer side of the base 1. The drain valve is connected to the inside of the grinding fluid collection chamber 7 so that the grinding fluid inside the grinding fluid collection chamber 7 can be discharged through the drain valve.
[0026] In this embodiment, a cross-shaped partition 4 is fixedly installed at the output end of the main electric rotary table 3, and the clamp is located at the angle of the cross-shaped partition 4 so as to shield the grinding process and prevent debris from flying.
[0027] In this embodiment, the fixture includes a secondary electric rotary table 5 and an electric chuck 6. The secondary electric rotary table 5 is fixedly installed at the output end of the main electric rotary table 3, and the electric chuck 6 is fixedly installed at the output end of the secondary electric rotary table 5, so that during the grinding process, the electric chuck 6 can be driven by the secondary electric rotary table 5 to rotate 360 degrees independently, thereby improving the flexibility of the grinding process.
[0028] In this embodiment, a plurality of cooling grooves 15 are evenly provided on the housing of the motor 9. The cooling grooves 15 are located in the cooling chamber 14 so as to increase the contact area with the grinding fluid, thereby better cooling the motor 9 and preventing the motor 9 from overheating during long-term operation.
[0029] It should be noted that all electrical components involved in this case are controlled by external controllers, such as PLC controllers. Since this is a very mature technology, it will not be discussed in detail here.
[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
