Polishing device and method for feeder line hole

Abstract

The invention discloses a polishing device and method for a feeder line hole. The polishing device for the feeder line hole comprises a base, an oscillator jig, a polishing rod supply assembly and a jig driving assembly. The base is provided with a containing space. The oscillator jig is mounted in the containing space in a horizontal sliding manner and is used for bearing an antenna oscillator. The polishing rod supply assembly is used for supplying a polishing rod to the oscillator jig. The jig driving assembly is arranged below the oscillator jig and is provided with a magnet driving block, and a rotary positioning groove is formed in the magnet driving block. The lower end of the oscillator jig extends to form a magnet connecting part extending out of the lower end face of the base, and the jig driving assembly drives the magnet connecting part to rotate through the magnet driving block. The polishing rod penetrates through the feeder line hole of the antenna oscillator and is inserted into the rotary positioning groove so as to determine the rotating center of the magnet connecting part. Automatic polishing of the feeder line hole is achieved, the problem that a good solution is not provided in the prior art for polishing and grinding of a rotating center needing deviation is solved, and the problem that the polishing precision is reduced due to tail end shaking in the polishing rod machining process is solved.

Description

technical field [0001] The invention relates to the field of antenna vibrator processing, in particular to a feeder hole polishing device and method. Background technique [0002] The AAU (Active Antenna Processing Unit) for 5G base stations mainly includes Massive MIMO antennas (large-scale antennas), filters, active components, etc. Antenna dipoles are most popular with dual-polarized antenna dipoles; Antenna oscillators also make their specifications emerge in endlessly. How to realize high-speed production of economical antenna oscillators is an important factor for the high cost and difficulty of popularizing 5G base stations at this stage. [0003] In the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology has at least the following technical problems: [0004] In the production process of the antenna vibrator, the polishing of the f...

Problems solved by technology

[0004] In the production process of the antenna vibrator, the polishing of the feed line hole and the polishing of the vibrator sheet have a great influence on the performance of the antenna vibrator; but in the polishing process of the feed line hole, since the feed line hole is not in the center of the antenna vibrator , to deal with the polishing and grinding that needs to shift the center of rotation, the existing technology does not have a good solution. Generally, a multi-degree-of-freedom manipulator is used to drive the polishing rod to rotate and grind. On the one hand, the processing efficiency of this method is low, and the high-precision control makes the cost On the other hand, it is difficult to solve the vibration of the end of the polishing rod, resulting in a decrease in the precision of the polishing, and it is difficult to meet the performance requirements of the antenna vibrator
