Problems solved by technology
[0004] However, due to the following two reasons, the above operation requires recalibration of the tool every time it moves a certain distance, which brings great inconvenience to the workers.
Specifically reflected in: there is no size mark and the travel distance of the tool cannot be known; 2. The various production working gaps in the machining process of the machine tool itself bring about the dimensional error of the processed parts

The invention relates to an adjusting control mechanism. The adjusting control mechanism is characterized in that a limiting bearing is arranged in the outer circumference of a main shaft of a machine tool; an inner ring of the limiting bearing is in interference fit with the outer circumference of the main shaft of the machine tool; the lower surface of an outer ring of the limiting bearing is lower than the inner ring; a cutter is arranged in the center of the lower end of the main shaft of the machine tool; a platform is arranged below the cutter; a guide plate is arranged on the platform; a drilling sleeve corresponding to the cutter in positions is arranged on the guide plate; a fine adjusting device is arranged in the main shaft of the machine tool. According to the adjusting control mechanisms, the working travel distance of the cutter for feeding up and down can be ensured, so that the processing precision of the diameter of a large end head or a small end head of the cone hole can be ensured.
Description
technical field [0001] The invention relates to an adjustment control mechanism and a method for processing a cylindrical taper hole, belonging to the field of mechanical processing. Background technique [0002] During the processing of cylindrical taper holes, it is often necessary to use any taper milling cutter or drill bit to process a certain taper cylindrical taper hole, so as to ensure the diameter of the taper hole at the large end of the taper hole or the diameter of the taper hole at the small end of the taper hole. [0003] Generally, the diameter of the taper hole at the large end of the taper hole or the diameter of the taper hole at the small end of the taper hole is controlled by the stroke of the tool’s up and down feed to control the length of the tool’s working path, ensuring that the diameter of the machining tool just matches the diameter of the taper hole at the large end of the taper hole Or the taper hole diameter size of the small end of the taper ho...
