Embodiment Construction

[0029] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, the present invention provides a method for processing mounting holes of antenna frame waveguide for satellites, comprising:

[0031] When milling, use the supporting clamping device and adopt the clamping method of "replacing pressure with support" to clamp the surface to ensure the flatness of milling;

[0032] Carry out a trial cutting test on the forming tool to determine the cutting parameters and the feed rate in the depth direction;

[0033] The forming tool is used to process the waveguide installation hole. When the waveguide hole on the product is finished, the tool is no longer set separately, but is compensated according to the height difference between the surface of the test piece a...

Abstract

The invention provides a method for processing waveguide installation holes of antenna frames for satellites. The invention adopts the forming tool to process the waveguide holes in an integrated manner, ensuring the coaxiality of the pin hole section and the screw hole section; using the support device The clamping device, "support instead of pressure", minimizes the deformation error caused by the clamping force during face milling. The processing efficiency, precision and reliability of the antenna frame waveguide installation hole are improved by adopting the process method and the accessory device proposed by the invention. It solves the problems that the quality and reliability of the high-precision waveguide hole of the satellite antenna frame cannot be guaranteed, and provides a reliable waveguide hole machining process, so that the pass rate of the waveguide hole can reach 100%.

Description

technical field [0001] The invention relates to a method for processing a mounting hole of a satellite antenna frame waveguide. Background technique [0002] The antenna frame used on a certain type of satellite is a glued structural member with carbon fiber as the main body, one of which is the installation surface of the waveguide device, and there are about 200 waveguide installation holes of the same structure evenly distributed on the waveguide surface within the range of 1700×1100mm ( Hereinafter referred to as waveguide hole). In order to ensure the installation accuracy of the waveguide device during the whole star assembly, the component state has high requirements on the size and shape accuracy of the waveguide hole. For the structure of a single waveguide hole, please refer to figure 1 , the pin hole diameter and hole depth accuracy requirements are high, and the coaxiality between the pin hole and the threaded bottom hole is ≤0.05. [0003] However, the traditi...
