Description

Technical field: [0001] The invention relates to an assembly method of a positioning car track and a driving tooth. Background technique: [0002] Today, the assembly line for positioning car tracks and drive gears consists of two lines, each 120.4m long, consisting of 86 pieces of 1.4m long drive teeth, 87 pieces of drive tooth support columns and 167 pieces of 0.7m long spur racks constitute. There are many parts involved in the assembly of the positioning car track and the drive gear, high dimensional accuracy requirements, special tooth shape specifications, high material hardness, and strict assembly requirements. The existing processing equipment is limited and cannot be processed. Invention content: [0003] The purpose of the present invention is to overcome the above disadvantages and provide an assembly method of the positioning car track and the driving gear which is convenient to operate, saves time and effort, and has high dimensional accuracy. [0004] The ...
