Turn-milling machining process method for gyroscope wire protecting plate

Abstract

The invention relates to a turn-milling machining process method for a gyroscope wire protecting plate. The method comprises the step (1) of clamping a workpiece on a lathe for the first time; the step (2) of drilling concentric inner hoes on the lathe; the step (3) of milling an arc groove on the lathe; the step (4) of performing drilling and counter boring on the lathe; the step (5) of fine boring the inner holes on the lathe; the step (6) of finish-turning an outer circle on the lathe; the step (7) of cutting off the workpiece on the lathe; the step (8) of turning over and clamping the workpiece on the lathe for the second time; the step (9) of turning a back side groove and finish-turning the end face on the lathe; and the step (10) performing metering, detection, cleaning, packaging and warehousing. According to the method, a turn-milling machining process is adopted in the machining process of the gyroscope wire protecting plate creatively, and the machining of the workpiece canbe finished on the lathe only; the clamping number of the process is decreased to 2 from 5, and the clamping number of the workpiece is decreased effectively; the auxiliary machining time is shortenedgreatly, and the part machining cost is reduced; the machining efficiency is improved; the method can meet the requirements of small-batch production and large-batch production of the gyroscope wireprotecting plate, and can be popularized in the production and machining of related sheet parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to the processing of gyroscope wire guards, in particular to a turning-milling composite processing method for gyroscope wire guards. Background technique [0002] The gyroscope wire guard is the key structural part of the gyroscope component, which belongs to the thin sheet part, and the structural features are mostly arc type, and the material is LY12-CZ aluminum alloy; the outer surface of the part has 7 uniformly distributed arc grooves, The end of each trunking is distributed with 3 through holes arranged in a specific order, with diameters of φ1.8mm, φ0.8mm and φ0.8mm respectively. In addition, there are 7 through holes designed in addition to the arc grooves on the outer surface of the wire guard parts. In order to ensure the shape and position accuracy of the wire guard structure, all the arc structures of this part have high indexing accuracy requirements, all ...

Problems solved by technology

[0015] It has been proved by the processing practice that although this process scheme can meet the processing requirements of the wire guard, due to the combination of turning and milling, the processing of the wire guard parts includes a large number of process clamping times, resulting in the processing of the wire guard. The auxiliary processing time is long, which seriously affects the processing efficiency; and the key structure of the part has high indexing accuracy requirements, and the multiple clamping of multiple types of work leads to the accumulation of clamping errors, which seriously reduces the processing accuracy and quality of the part. , there is a risk of out-of-tolerance accuracy, and at the same time increases the processing difficulty of the parts and reduces the processing efficiency of the parts

In addition, since the machining of the hole and arc groove of the part needs to be completed by the machining center, it is a typical example of single-person single-machine machining, and the machining process of the wire guard is multi-work processing, so that the machining process of the part Occupying a large amount of equipment resources in the turning and milling machining center, and consuming multiple types of labor such as turning and milling, which greatly increased the production cost of this part, resulting in the processing of wire guard parts becoming a key bottleneck in the supporting production of gyroscopes
