Cylinder body inner hole numerical control cylindrical coordinate chamfering machine

Abstract

The invention discloses a cylinder body inner hole numerical control cylindrical coordinate chamfering machine. The numerical control cylindrical coordinate chamfering machine comprises a main machine, a grinding mechanism and a numerical control operating system. The main machine further comprises a lower machine body, a Z-axis advancing mechanism and an X-axis rotating mechanism, wherein a Z-axis servo motor of the Z-axis advancing mechanism is connected with a lead screw, a nut installed on the lead screw is connected with a cylindrical pin, the cylindrical pin is connected with a spline shaft, the spline shaft is located in the lower machine body, a mandrel is arranged above the spline shaft, a bull gear is arranged on the mandrel, and the upper part of the bull gear is connected with a main shaft; a X-axis servo motor of the X-axis rotating mechanism is connected with a small gear, and the small gear is engaged with the bull gear; and a grinding mechanism is arranged on the main shaft, the grinding mechanism further comprises a grinding head and a grinding head sleeve, the grinding head is connected into the grinding head sleeve through an expansion sleeve, and the grinding head sleeve is arranged on the main shaft. The Z-axis servo motor is used for controlling the lower machine body to move up and down, the X-axis servo motor is used for controlling the grinding mechanism to rotate, automatic chamfering can be achieved, chamfers are consistent in size and free of omission, the quality is uniform, and the training cost is low.

Description

technical field [0001] The invention relates to the field of machining cylinder hole wall chamfering, in particular to a numerically controlled column coordinate chamfering machine for cylinder inner holes. Background technique [0002] In the production process of small air-cooled gasoline engine cylinders, the chamfering of cylinder scavenging passages and intake and exhaust passages is a major problem in the entire industry; no matter at home or abroad, there is no mechanized automatic chamfering equipment. At present, the entire All industries use manual chamfering; not only the quality of manual chamfering is not guaranteed, the chamfering can be large or small, and even omissions, but also labor-intensive and technically demanding. It takes a long time to train a qualified operator, and at the same time the efficiency is very high. Low. Contents of the invention [0003] In view of the problems existing in the prior art, the present invention discloses a numerically...
