Embodiment Construction
[0032] A method for manufacturing an adjustable positioning device for positioning processing of the rear end of a lathe, including a positioning interface of the lathe, comprising the following steps:
[0033] Step 1. Take the positioning sleeve of the required length. The aperture of the positioning sleeve is smaller than or equal to the aperture of the inner hole of the positioning interface. positioning ladder;
[0034] Step 2. Bore the inner hole at the rear end of the positioning interface to form an axial positioning step corresponding to the front end of the positioning sleeve, put the front end of the positioning sleeve into the inner hole at the rear end of the positioning interface to form a sliding fit, and place the positioning sleeve , The positioning interface is welded and fixed together;
[0035] Step 3. Take the positioning plug with an axial center hole, turn the outer circle of the front end of the positioning plug to form an axial positioning step corresp...

Abstract
The invention discloses a manufacturing method of an adjustable positioning device used for lathe rear end positioning and machining. The manufactured adjustable positioning device can position workpieces of various specifications by adjusting. The manufacturing method comprises the following steps that 1, a positioning tube sleeve of a needed length is taken, the outer circle of the front end ofthe positioning tube sleeve is turned, and an inner hole of the rear end of the positioning tube sleeve is bored; 2, an inner hole of the rear end of a positioning interface is bored, and the front end of the positioning tube sleeve is put into the inner hole of the rear end of the positioning interface to form sliding fit and fixation; 3, a positioning plug block with an axial center hole is taken, the outer circle of the front end of the positioning plug block is turned, and the front end of the positioning plug block is put into the rear end of the positioning tube sleeve and fixed; 4, a positioning block and a connection rod which are of an integrated structure are turned; 5, an axial positioning groove in the connection rod is milled and machined; 6, the rear end face of the positioning plug block is turned, and a threaded hole for mounting a fastening screw is drilled; 7, the positioning block and the connection rod are quenched; and 8, assembly is conducted.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to a manufacturing method of an adjustable positioning device used for positioning the rear end of a lathe. Background technique [0002] In the existing technology, the process route of the workpiece is determined at the early stage of product development, and the corresponding product tooling is customized. The positioning cylinder is the most basic tooling in the turning process. In the long run, there are more and more types of developed products, and more and more positioning tooling, resulting in various problems: [0003] On the one hand, the number of positioning tooling is increasing, and the similarity is extremely high, so it is easy to take it wrong, resulting in poor positioning effect and poor product stability; [0004] On the other hand, a large number of positioning tools not only cause more waste in cost, but also are not easy to effectively manage and store. ...
