Thin-wall thread bushing machining tool

Abstract

The invention relates to a thin-wall thread bushing machining tool. A top cover is connected with an end cover through a mandrel, the outer wall of the top cover is provided with a first top cover outer circle wall used for being clamped by a three-jaw chuck, a second top cover outer circle wall used for being matched with the inner wall of a workpiece and a top cover bench used for abutting against the end face of the workpiece, a top cover through hole is further formed in the axis of the top cover, a locking key is arranged between the top cover through hole and the mandrel, the end cover outer wall is provided with an end cover outer circle wall matched with the inner wall of the workpiece and an end cover bench used for abutting against the end face of the workpiece, an end cover blind hole is further formed in the axis of the end cover, and the blind hole end of the end cover blind hole is connected with the end face of the mandrel through a first fastening bolt and a limiting pin. Threads are further arranged on the end cover outer circle wall of the end cover. By the adoption of the structure of the thin-wall thread bushing machining tool, it is guaranteed that the workpiece can not be deformed in the machining process, the one-time inspection application pass percent of the workpiece reaches about 98%, and the aim of machining nylon-material thin-wall thread bushing parts is fundamentally achieved.

Description

technical field [0001] The invention relates to the field of processing tooling, especially a clamping tool for processing the outer circle of thin-walled workpieces on a lathe, in particular a processing tool for clamping thin-walled threaded sleeves of carbon steel or even nylon thin-walled parts . Background technique [0002] Thin-walled parts are often widely used in modern design. It has many advantages, such as light weight and convenient assembly, etc., and plays an irreplaceable role in many fields. However, precisely because of its thinner outer wall shape, it also brings many technical difficulties to the processing. [0003] For ordinary carbon steel thin-walled parts, because the wall thickness of the part is very thin, it is easy to deform during clamping, and the heat generated by the turning tool chips also affects the part, so it will cause the part size to be out of tolerance after processing Case. For thin-walled parts made of nylon, it is even more dif...

Problems solved by technology

[0003] For ordinary carbon steel thin-walled parts, because the wall thickness of the part is very thin, it is easy to deform during clamping, and the heat generated by the turning tool chips also affects the part, so it will cause the part size to be out of tolerance after processing Case

For thin-walled parts made of nylon, it is even more difficult to control its deformation.

Through experiments, if nylon thin-walled parts are clamped by ordinary methods, the pass rate of the parts is less than 5%, and the scrap rate is very high
