A kind of technical method of installing meson on metal lamp tube

Abstract

The invention discloses a technical method for mounting a meson on a metal lamp tube. The method comprises the steps that (1) a tube hole with the diameter of 3-5mm is drilled in a position where the meson needs to be mounted on the metal lamp tube; (2) a hot melting drill with the diameter of 6-9mm is used for hole expanding on the tube hole, through generation of heat by friction, the tube wall around the tube hole is softened and extends into the tube in the radial direction along with going deep of the hot melting drill, after cooling, a wrapping position protruding into the tube is formed; (3) an M8 or M10 screw tap is used for thread tapping of the wrapping position; (4) the meson sleeves a universal connector, and the end portion of the universal connector is placed on the tube hole and is screwed into the wrapping position on the lamp tube. The technical method has the advantages that the process for welding the meson is removed; during a lamp tube electroplating process, automatic polishing can be used in a first layer polishing procedure, 60% of time and 30% of polishing cost can be saved, surface processing time can be greatly shortened; rejection rate is low, cost is lowered; workpieces cannot be damaged easily during a mounting process; appearance decorating effect is attractive.

Description

technical field [0001] The invention relates to the field of lighting installation, in particular to a technique for installing branch lamp tubes with metal lamp tubes with wires inside. Background technique [0002] At present, in the lighting industry, metal lamp tubes are commonly used to protect the wires, and the wires are generally worn in the metal lamp tubes. In the case of branch lines, the main metal lamp tube and the branch metal lamp tubes are connected through universal joints. There are usually decorative and transitional metal mesons at the junction of the connector and the metal lamp tube. Because the tube wall of the lamp tube is thin, the number of thread turns after drilling and tapping is small, and the universal joint cannot be completely fixed. The universal joint needs to be fixed with the assistance of mesons. The meson is fixed on the drilled pipe hole. The current technological method of installing the metal meson is: first drill the metal lamp t...

Problems solved by technology

Although this processing method is simple, convenient, and easy to implement, it also has the following defects: high processing waste rate; due to the obstruction of metal mesons, the surface polishing process of metal lamp tubes is complicated; the time for welding surface treatment is long; it is easy to damage during assembly The workpiece; mesons are limited to those made of metallic materials
