The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a clamping device for improving precision of a saw blade comprises a saw blade 100, and further comprises a driving assembly 1, a fixing seat 2 and a wear-resisting piece 3, wherein an output end of the driving assembly 1 is connected with the fixing seat 2, the fixing seat 2 is driven to do reciprocating linear motion, and the wear-resisting piece 3 is vertically arranged on the side surface of the fixing seat 2 and is attached to the lower side of the saw blade 100. Specifically, in this embodiment, the driving component 1 may be an air cylinder, an electric push rod, or a hydraulic push rod, so long as the fixing seat 2 can be driven to do reciprocating rectilinear motion. When the fixing seat 2 is displaced, the saw blade 100 is driven to do linear motion, so that the wear pad 3 at the side part of the fixing seat 2 is always attached to the lower hem of the saw blade 100, and the displacement speeds of the fixing seat 2 and the saw blade 100 are kept consistent. The wear pad 3 can play a role of limiting the saw blade 100, and prevent the large-sized saw blade 100 from swinging down during the cutting process, resulting in large difference in machining allowance and reduced precision of machined products. The wear-resistant sheet 3 is made of tungsten steel, and has the advantages of high strength, wear resistance, long service life and low use cost.
