Embodiment Construction

[0025] Such as figure 1 with figure 2 As shown, the automatically adjustable backing of the instrument lathe is located between the small carriage 9 and the large carriage 10 of the instrument lathe. It is composed of backing body 1, positioning screw 2, mandrel 5, base 8 and fork 3 and other parts.

[0026] Such as figure 2 with Image 6 As shown, a backing body 1 is provided on the large carriage 10. The backing body 1 is cylindrical and is sleeved on a mandrel 5. The mandrel 5 is fixedly connected to the large carriage 10. The backing body 1 can rotate around the mandrel 5.

[0027] Six unidirectional teeth 1a are evenly distributed along the circumferential direction on the lower part of the backing body 1. At the same time, as Image 6 As shown, the lower end surface of the backing body 1 also has six evenly distributed notches 1b. Six positioning screws 2 are fixedly connected to the upper outer surface of the backing body 1, and the positioning screws 2 are in one-to...

Abstract

An automatically adjustable backer of instrument lathe for controlling the stroke of tool carriage is installed between the small and big tool carriages, and is composed of a cylindrical backer body, a mandrel fixed to big tool carriage, several locating screws with different lengthes and arranged uniformly along the external surface of said backer body and an adjusting unit on small tool carriage for adjusting the rotation of backer body.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and relates to an instrument lathe, in particular to a device for controlling the stroke of a carriage on an instrument lathe. Background technique [0002] In the instrument lathe, the tool holder where the tools are placed is fixed on the carriage. The workpiece is processed by moving the carriage. The backer is used to limit the stroke of the carriage to control the feed amount of the tool. [0003] At present, in the instrument lathe, when processing a workpiece, the backing is always fixed. If you need to change the backing position, you must adjust it when the lathe stops running. Moreover, the adjustment of the backing position is very troublesome. [0004] In some processing procedures of the workpiece with the instrument lathe, such as cutting the thread on the workpiece, the carriage needs to be moved multiple times, and the stroke of each movement is different because the workpiece cannot...
