Novel lathe grinding head device

The invention discloses a novel lathe grinding head device which comprises a grinding wheel, a shaft and an end cover. The grinding wheel is connected with the shaft in a sleeving manner. One end of the shaft is connected with a shell through conical roller bearings, and the other end of the shaft is connected with the shell through a deep groove ball bearing. The lower end face of the shell is fixedly connected with a base. A motor is arranged at the upper end of the base. A second belt wheel is arranged on one side of the motor and is connected with a first belt wheel through a belt. According to the novel lathe grinding head device, the structures of the two conical roller bearings are adopted at the end of the grinding wheel to replace an original single deep groove ball bearing structure, the stability of the shaft at the end of the grinding wheel in the grinding process is increased, the grinding precision is improved, and the bearing service life is prolonged; when the conical roller bearings are worn
