Spindle transmission mechanism of table type drilling and milling machine

Abstract

The invention discloses a main shaft transmission mechanism of a desktop drilling and milling machine, which belongs to the technical field of mechanical device design, including a main shaft box, a skeleton oil seal, a motor, a protective cover, an angular contact ball bearing, a main shaft box cover, a spline sleeve, and a shift handle , tapered roller bearing, scale rod, support ring, main shaft, main shaft sleeve, gear, the motor is fixed on the rear side of the main shaft box to the left, the main shaft is set on the right side inside the main shaft box, and the main shaft is supported in the main shaft sleeve by tapered roller bearings , the main shaft sleeve is fixed in the seat hole of the main shaft box, a spline sleeve is installed on the second half of the main shaft, and a shift handle is located on the right side of the main shaft box near the front of the main shaft box cover, and a scale is set on the right front inside the main shaft box Rod, the main shaft transmission mechanism of the desktop drilling and milling machine disclosed in the present invention, the lubricating oil is not easy to leak, the scale rod is fixed and reliable, the transmission precision of the gear is high, the service life is long, and the external medium has little influence on the main shaft.

Description

technical field [0001] The invention relates to the technical field of mechanical device design, in particular to a main shaft transmission mechanism of a desktop drilling and milling machine. Background technique [0002] With the popularization of family cars, many families have begun to pay attention to the maintenance of cars after a period of use. The expensive 4S charges make many families discouraged when cars break down. Therefore, more and more families hope to solve the problems of family cars by themselves. The small faults that occur during use will increase the demand for small drilling and milling machines. The machine tool spindle box is a mechanical component that supports the spindle. The spindle passes through it, and there is a bearing between the shaft and the spindle box. Some auxiliary parts on the existing spindle box are not complete enough, and it takes a lot of auxiliary time to adjust the machine tool, and the efficiency is low. Some machine tools ...

AI Technical Summary

Problems solved by technology

Some auxiliary parts on the existing spindle box are not complete enough. It takes a lot of auxiliary time to adjust the machine tool, and the efficiency is low. Some machine tools lack appropriate protection devices. Impurities are easy to enter the spindle box, resulting in easy damage to the machine tool
