Abstract

The invention discloses an axis adjustment method of a boring head. According to the axis adjustment method, the rotation axis of a main shaft of the boring head and the feeding movement direction of the boring head can be conveniently adjusted to be parallel. A large hole in the upper part of a component is bored by using a boring cutter on the main shaft; a dial gauge is arranged on the main shaft of the boring head, so that a measuring head of the dial gauge is arranged at the position of the boring cutter of a small hole on the lower part of the bored component on the main shaft; the measuring head of the dial gauge is pressed on the wall of the large hole in the upper part of the bored component; the main shaft is turned, and the measured value of the dial gauge is zero though four adjusting screw barrels on a disc on the upper edge of the boring head body; the connection of the boring head and a stand is adjusted for many times by using the method, so that the adjusting screw barrels are fixed to the boring head body by using locking nuts after the rotation axis of the main shaft of the boring head is parallel to the feeding movement direction of the boring head, and long bolts penetrate through the locking nuts and spherical washers to fix the boring head body to the stand; studs of short bolts are arranged in four small screw holes in the disc on the upper edge of the boring head body; and after the upper end faces of the studs of the short bolts are tightly pressed against the lower surface of the stand, each short bolt is locked by using the nut. The adjustment method has the advantages of rationality in positioning, easiness in operation and capability of quickly adjusting the parallelism of the rotation axis of the main shaft of the boring head and the feeding movement direction of the boring head to be within the required accuracy of machined components.

Description

Technical field [0001] The invention relates to a mechanical processing method, in particular to a method for adjusting the axis of a boring head. Background technique [0002] All technicians in the same industry know that the parallelism error between the axis of rotation of the spindle of the boring machine and the direction of feed is one of the main precision parameters of the boring machine. When machining two holes that are in different positions and require coaxiality, if the two holes are not machined with the boring tool at the same position on the main shaft of the boring machine, their coaxiality will have errors. For example, the valve seat hole and the valve guide mounting hole of the cylinder head of a high-power internal combustion engine. The valve seat hole with a diameter of 90 mm and a length of 22 mm is more than 120 mm from the conduit installation hole with a diameter of 28 mm and a length of 80 mm. It is processed with a corresponding boring tool ins...
