Embodiment Construction

[0038] Such as figure 1 , 2 As shown, on the workbench 11 of the table saw 100, a positioning groove 13 is provided on the surface for placing the workpiece, and the saw blade 15 extends out of the workbench 11 to saw the workpiece, and the plane angler (not shown) is placed on In the positioning groove 13 , the positioning groove 13 provides a guide for the plane angler, and the plane angler is used to abut against the workpiece (not shown), so as to perform oblique cutting on the workpiece.

[0039] The saw blade 15 has a first end 151 and a second end 153. The vertical distance from the first end 151 to the positioning groove 13 is d1, and the vertical distance from the second end 153 to the positioning groove 13 is d2. To improve the cutting quality of the workpiece, it is necessary to Ensure the parallelism between the saw blade 15 and the positioning groove 13, that is, ensure that the deviation of the saw blade d1-d2 is as small as possible. Ideally, d1-d2=0 is require...

Abstract

The invention discloses a table saw which comprises a working platform, a rotating shaft arranged under the working platform, a swing part pivoted on the rotating shaft, a rotary swing part pivoted on the swing part by a pin shaft, a motor that is fixedly arranged on the rotary swing part and is provided with an output shaft, a saw blade connected on the output shaft of the motor, and an eccentric part, wherein one side of the rotary swing part is provided with a containing hole; and the eccentric part is contained in the rotary swing part and passes through the pin shaft. The eccentric part is arranged on the rotary swing part and passes through the pin shaft, and the saw blade can be adjusted to be parallel to the rotating shaft by rotating the eccentric part, so that the table saw is very convenient for operation, simple in structure and lower in manufacturing cost.

Description

technical field [0001] The invention relates to a table saw, in particular to a saw blade parallel adjustment mechanism of the table saw. Background technique [0002] Chinese Patent No. CN2889578Y published on April 18, 2007 discloses a table saw, which includes a workbench for placing workpieces to be cut; the above workbench is provided with positioning grooves for placing plane angles The plane angler is used to lean against the workpiece, so as to cut the workpiece obliquely; the table saw also includes a rotating shaft arranged under the above-mentioned workbench; a swing member pivotally arranged on the above-mentioned rotating shaft; pivotally arranged on the above-mentioned The swing piece on the swing piece; the motor arranged on one side of the swing piece, the motor has an output shaft; the output shaft of the motor is provided with a saw blade, which is used to drive the saw blade to rotate, so as to cut the workpiece. [0003] It should be emphasized that due ...
