A spindle tail hole top device and method capable of expanding the clamping length of a lathe

Abstract

The invention discloses a main shaft tail hole tip device and method capable of enlarging the clamping length of a lathe. The device comprises a locating sleeve connected to a main shaft of the lathe.One end of the locating sleeve is inserted into a tail end inner hole of the main shaft of the lathe in a penetrating manner, and an adjusting and fixing ring is connected to the other end of the locating sleeve. A hole opening of the adjusting and fixing ring and an outer circle of the tail end of the main shaft of the lathe are fastened by the adoption of threads. A tip body is installed in thelocating sleeve in an inserted manner. The free end of the tip body is connected with a tip. The tip and a long shaft part inserted into the tail end inner hole of the main shaft of the lathe are aligned and abut against each other. A center hole is machined in the end face of one end, aligned to and abutting against the tip, of the long shaft part. The device can ensure that clamping of the longshaft part is concentric, and on the premise of meeting the machining quality, the problem that due to limitation of the specification of the lathe, the maximum length of the part capable of being clamped by the lathe is limited is solved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a spindle tail hole top device and method which can expand the clamping length of a lathe used in the processing of long-axis parts. Background technique [0002] When turning long-axis parts, it is necessary to choose a lathe that can meet the processing length of the part. However, in actual production, there is often the problem that the maximum length of the parts that the lathe can clamp cannot meet the requirements. When the length of the part to be clamped exceeds the capacity range of the maximum length of the part that can be clamped by various types of lathes in the production site, it is generally considered that these lathes cannot turn the long-axis part. In order to solve this problem, the traditional method also has a section of the long-axis part that is not processed is directly inserted into the lathe spindle hole without any centering device, s...
