Embodiment Construction
[0016] The embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0017] See attached Figure 1 to 3 , figure 1 It is a partial structure diagram of the tail part. The two structures O and R in the figure need to be chrome-plated. The improvement method of the tail part tooling includes the following steps:
[0018] (1) Draw a diagram of the cathode protection ring to be manufactured according to the chromium plating requirements and shape characteristics of the parts;
[0019] By the attachment figure 1 The part surfaces at the two ends of the part that are connected at O of the part cannot be kept in the same plane, and the right-angle edge effect of the part is prone to chromium accumulation, so the chromium-plated surface extension principle is used to solve the phenomenon of chromium accumulation;
[0020] By the attachment figure 1 Because the part surface is arc-shaped and non-chrome-plated at R in the part...

Abstract
The invention discloses an improvement method of an empennage part tool. The improvement method comprises the following steps that (1) the drawing of a cathode guide ring to be manufactured is drawn according to the part chromeplate requirement and shape characteristics; (2) proper metal materials are selected for manufacturing; (3) manufacturing is carried out according to the requirement of the drawing of the cathode guide ring; and (4) the cathode guide ring is tested after being manufactured, and improvement is carried out when necessary. The design of the cathode guide ring is adopted, so that the problem of size tolerance in a connecting end opening of a non-chromeplate portion and a portion needing chromeplate is solved, and the defects caused by a traditional insulation method are overcome. Operation is easy and convenient; the reworking rate and rejection rate are lowered; production efficiency is greatly improved; production cost is lowered; the surface production quality of products is improved; the delivery cycle of parts is guaranteed.
Description
Technical field [0001] The invention belongs to the technical field of mechanical processing, and particularly relates to a method for improving the tooling of tail parts. Background technique [0002] Aircraft tail parts are key parts and are key parts. The material is high-strength steel, the parts are large, and the surface treatment is local hard chrome plating. The remaining parts need to be insulated. During the operation, there are the following problems: [0003] The chrome-plated parts of the parts have multiple dimensions, not only the basic dimensions of the parts are different, but also there can be no local over-tolerance. If it is out of tolerance, it is difficult to re-grind due to the complex shape and structure of the part, and it is easy to wear off, causing rework. Moreover, since high-strength steel parts are only allowed to be repaired once, the scrap rate of parts is greatly increased, the production cycle of parts is prolonged, and the processing cost is inc...
