Description

Technical Field

[0001] The utility model belongs to the technical field of linear positioning mechanisms, and relates to a linear positioning mechanism of a fan inner wheel key groove drawing machine. Background Art

[0002] When installing a travel wheel or a transmission wheel on a transmission shaft, they are usually connected by a key. In this way, a keyway needs to be opened on the travel wheel and the transmission wheel. The keyway is mainly formed by pulling the key on the inner ring of the gear through a key pulling machine. The key pulling machine includes a clamping member for clamping the fixed gear position, a horizontally movable key pulling knife, etc. The key pulling knife passes through the inner ring of the gear during the horizontal movement and forms a keyway on the top of the inner ring of the gear. When the existing keyway pulling machine slots the gear or the transmission wheel, the key pulling knife is manually inserted into the inside. After each workpiece is completed, it is inserted again. This will cause a linear deviation during the insertion, thereby affecting the processing quality of the keyway. Repeating this operation increases the amount of manual labor and reduces work efficiency. Therefore, in view of the above problems, a linear positioning mechanism of a fan inner wheel keyway pulling machine is proposed. Utility Model Content
