Description

Combination saw

The utility model relates to a kind of combination saw, claims combined cutting machine again.

The main base of existing combination saw, column, cantilever, saw blade seat, motor, formations such as saw blade, motor, saw blade, saw blade seat is formed working head, working head passes through cantilever, column is installed on the base top, working head is cantilever relatively, column, the base certain angle that in plane, saw blade place, sways, the swaying of working head makes saw blade be fixed on the relative displacement that workpiece produces oscilaltion that is cut on the base relatively, thereby realize that saw blade is to being cut the cutting of workpiece, but, foregoing base, column, cantilever is mutually permanently connected, working head and saw blade are except carrying out the cutting movement of oscilaltion, base carries out other direction relatively, the position in orientation is adjusted, and therefore this combination saw has the more limited shortcoming of cut coverage.

The purpose of this utility model provides the bigger combination saw of a kind of saw blade cut coverage.

To achieve these goals, technical solution of the present utility model is such: a kind of combination saw, mainly by base, column, cantilever, saw blade seat, motor, formations such as saw blade, motor, saw blade, saw blade seat is formed working head, working head passes through cantilever, column is installed on the base top, working head is cantilever and the base certain angle that sways in plane, saw blade place relatively, wherein the main body of cantilever is a slide bar, the column top is provided with sliding sleeve, the outer surface of slide bar is provided with the ball groove with the sliding pole axis line parallel, the inner surface of sliding sleeve is provided with the ball mounting groove parallel with the sliding sleeve axis, in the ball mounting groove ball is housed, the sliding sleeve ball groove interior and slide bar that slide bar is installed on column matches with the ball that is installed in the sliding sleeve inner surface, the part of ball is absorbed in the ball mounting groove of sliding sleeve, another part is absorbed in the ball groove of slide bar, sliding sleeve and column are in axial sliding and can not sway relatively to make slide bar, also be provided with a trip bolt on the sliding sleeve, slide bar was free to slide when trip bolt unclamped, and headed on slide bar when trip bolt is tightened and made it relative sliding sleeve and maintain static.

Because in the above-mentioned technical solution, the connected mode of cantilever and column is by original fixedly connected being improved to by slidably being connected that sliding sleeve, slide bar constitute, and the outer surface at slide bar is provided with the ball groove, the sliding sleeve inner surface is provided with ball mounting groove and ball, therefore when allowing the relative column slippage of cantilever to adjust, also can limit rotating of slide bar, make the operating position of saw blade can obtain with the slippage of the relative column of cantilever adjusting, just enlarge the cut coverage of saw blade around its axis.
