Installation method of shunt module cabinet body upper support frame piece and positioning tool for installation

Abstract

The invention discloses an installation method of shunt module cabinet body upper support frame pieces and a positioning tool for installation. The positioning tool comprises a vertical board, a horizontal board with one end vertically connected with the vertical board and a positioning board connected with the other end of the horizontal board. The positioning board is provided with two positioning holes, and the vertical board is provided with four fixing holes. When the support frame pieces are installed, the fixing holes correspond to four installation holes in a cabinet body in a one-to-one mode, and screws are inserted and tightly screwed. First piece boards of the two support frame pieces are then attached to a top board of the cabinet body, and two second piece board on the two support frame pieces are attached with the positioning board. Threaded holes in the second piece boards of the support frame pieces correspond to the positioning holes, and screws are inserted and screwed. Finally, arc welding is performed, cooling is performed to normal temperature, the screws are screwed out, and the positioning tool is taken out. The installation method of the shunt module cabinet body upper support frame pieces and the positioning tool for installation has the advantages that positions of the support frame pieces in the cabinet body are precise, deviation does not exist, and therefore when a shunt module is placed into the cabinet body, the shunt module can be matched with the support frame pieces precisely.

Description

technical field [0001] The invention relates to a method for installing a support piece on a splitter module cabinet and a positioning tool for installation. Background technique [0002] The splitter module is a product used in the computer room of the communication center and the access network system. Such a splitter module is also installed on the train. [0003] The shunt module on the bullet train is generally installed in a cabinet. In order to prevent the shunt module from being damaged by the running vibration of the train, the common method is to first weld and install two brackets in the assembled cabinet, and then install the The splitter module is installed in the cabinet, and the card slot on the splitter module cabinet will be connected with the bracket piece, so that the splitter module is fixed in the cabinet. The two brackets are generally directly welded in the assembled cabinet. In order to install the splitter module into the cabinet normally, the posit...

AI Technical Summary

Problems solved by technology

The two brackets are generally directly welded in the assembled cabinet. In order to install the splitter module into the cabinet normally, the positions of the brackets are measured before welding. This method is theoretically feasible. However, in the actual production process, due to the influence of unavoidable human factors, welding deformation and displacement often occur. This kind of error will lead to assembly failure. Even if it can be assembled, it will be due to a little misalignment. As a result, the bracket piece is broken due to uneven force, which affects the stability of the splitter module in the cabinet, and even damages the splitter module

This not only caused a lot of rework, wasted manpower and material resources, but also delayed the normal delivery time of the product, affecting the company's reputation
