Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of connection structure 10 of spindle encoder and screw mandrel support seat is provided in the present embodiment, including：
Lead screw 11, encoder 12, fixed pedestal 13, first flange disk 14, second flange disk 15, shaft coupling 16 and protective cover 18.
The lead screw 11 is rotatably arranged on by bearing in the fixed pedestal 13, and the side of the lead screw 11 is provided with connection
Axis device 16, shaft coupling 16 are connected to encoder 12.The encoder 12 is fixed on the first flange disk 14, and described
One ring flange 14 is fixed at one end of the fixed pedestal 13, and the shaft coupling 16 is arranged in the lead screw 11 and encoder
12 centre position, the second flange disk 15 are arranged between the shaft coupling 16 and the fixed pedestal 13, and described
