High-speed grinding head device suitable for numerical control boring and milling machine

Abstract

A high-speed grinding head device suitable for numerical control boring and milling machines belongs to the technical field of grinding tools. The high-speed grinding head device comprises an electric spindle, a fixing mechanism, a support, a grinding wheel connecting rod and a grinding wheel. The support comprises an assembling part matched with a machine tool spindle and a support part matched with the fixing mechanism. The assembling part is located at one end of the support part and perpendicular to the same. The fixing mechanism is mounted on the support part. A through hole penetrating from left to right is reserved on the fixing mechanism. The electric spindle is mounted in the through hole and perpendicular to the assembling part. A positioning hole is reserved on the assembling part, the center of the positioning hole are on the same axis of the center of the electric spindle, an output end of the electric spindle is connected to one end of the grinding wheel connecting rod, and the other end of the grinding wheel connecting rod is fixed with the grinding wheel. Grinding of local special-shaped surfaces by medium and large numerical control boring and milling machines with spindle motor power larger than 30KW, and grinding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of grinding tools, and in particular relates to a high-speed grinding head device suitable for a numerically controlled boring and milling machine. Background technique [0002] In the field of machining, grinding is one of the most widely used processing methods. With the development of science and technology, many new materials such as hard and brittle materials, engineering ceramics, amorphous microcrystalline alloys and other difficult-to-process materials have emerged in large numbers. Although there are many processing methods for these materials, such as laser processing and electron beam processing, etc. The most practical processing method is still grinding. In particular, some workpieces have special-shaped surfaces locally, which must be completed by high-speed grinding. For CNC boring and milling machines with a spindle motor power of more than 30KV, the maximum spindle speed is usually below ...

AI Technical Summary

Problems solved by technology

For CNC boring and milling machines with a spindle motor power of more than 30KV, the maximum spindle speed is usually below 2000rpm. When the grinding wheel requires a high linear speed for high-speed grinding, the spindle speed of the machine tool itself is not enough to provide the normal working linear speed of the grinding wheel. Unable to complete the grinding process on the local profiled surface
