Description

Technical Field

[0001] The utility model relates to the technical field of sliding table saws, in particular to a ruler positioning device for a sliding table saw. Background Art

[0002] At present, the common precision sliding table saws on the market generally require a long ruler and a baffle on the left side to position the wood according to the size of the board during the sawing process, while the traditional precision sliding table saw uses a long ruler on the left side and a baffle on the left side to position the size of the left sawing by manually aligning it with the ruler line, and the size adjustment method of the baffle block of the long ruler on the left side is to manually adjust the slide to move the baffle block left and right for positioning.

[0003] In the existing equipment, a workbench is used, and a box is fixedly connected to the front side of the workbench near the top. First sliding grooves are opened at the left and right sides of the inner cavity of the box near the bottom. The inner cavities of the two first sliding grooves are slidably connected with a first slide plate. Threaded sleeves are penetrated through the top of the first slide plate near the left and right sides. The inner cavities of the two threaded sleeves are threadedly connected with threaded rods. The top and bottom ends of the two threaded rods are inserted into the adjacent side of the inner cavity of the box. A second sliding groove is opened at the bottom of the first slide plate, and the left and right sides of the inner cavity of the second sliding groove are slidably connected with second slide plates, so as to realize the locking effect of the ruler at different positions.

[0004] However, during actual use, although the above-mentioned device can lock the ruler at different positions, a large amount of wood chips are easily accumulated on the slide slot of the ruler and the upper end of its components when cutting the board. When too much wood chips are accumulated in the slide slot, it is easy to cause the forward path deviation, resulting in inaccurate positioning and cutting of the board. In view of this, we propose a ruler positioning device for a sliding table saw. Utility Model Content
