Abstract

The utility model relates to a spiral planing tool of a woodworking machine clamp, which is provided with a cylindrical planing tool body, wherein, the center of the planing tool body is provided with a through hole; a cylinder surface is evenly provided with rectangle trapezoid curved surface blades along the direction of a plurality of helix lines with equal distance; a trapezoid inclined side is welded with a hard alloy planing edge of which curved degree is consistent with the helix line; the blades are fixed on the planing tool body through spiral nails; the spiral planing tool and the planing edge of the machine clamp are contacted with workpieces in a point form. The utility model has the advantages of small cutting resistance and no stubble collapse. Besides, the body of the planing tool can be replaced and the utility model can be heavily milled.

Description

Carpenter's machine clamp screw planing tool

The utility model relates to the machine clamp screw planing tool that a kind of carpenter uses, and it is applicable to that the plane (milling) on timber plane cuts processing.

Current art material flat and process tool, the most widely used is the planing tool with dull and stereotyped plane iron, cutting edge is that line contacts with workpiece in the process, cutting resistance is big, is easy to generate in the process to collapse a batch phenomenon, the plane that digs is being affected qualitatively; Also there is the planing tool that adopts integral type screw type plane iron the home and abroad, but it is non-exchange, scraps with cutter hub behind wearing and tearing or the tipping, and plane iron can not be refaced in the use.

The machine clamp screw planing tool that the utility model provides has realized that plane iron is replaceable, can reface, because plane iron and workpiece plane are to contact, cutting resistance is little, does not produce to collapse a batch phenomenon.

The planing tool cutter hub is cylindric on the structure for this reason, and the post center is a manhole, cuts etc. dark equidistant and perpendicular to the rectangle groove of cutter hub axis on the face of cylinder; Along the uniform hand of helix of several standoff distances, to terminal, blade is installed equidistantly by origin or beginning; Blade is at right angles trapezoidal, and last bottom is parallel with rectangle groove, and right-angle side is vertical with rectangle groove; Hypotenuse is consistent with hand of helix, and is welded with the carbide alloy plane iron identical with the helix curvature on the hypotenuse, and whole blade is a curved surface, and matches with the cutter hub periphery; Each blade all is fixed on the cutter hub with a screw; Along the blade of installing on adjacent two hand of helixs, in configuration, be along the staggered location of rectangle groove direction; The columns of the radical of helix--blade can be two row, three row, four row, five row, six row.

Now specify its architectural feature by drawings and Examples:

Accompanying drawing 1 is carpenter's machine clamp screw planing tool front view

Among the figure: 1. cutter hub; 2. blade; 3. screw; 4. rectangle groove; 5. blade sectional drawing; 6. carbide bit;

This planing tool adopts four helix forms to arrange, and row has four blades on the every line.

Claims

1. be used for carpenter's machine clamp screw planing tool on converted timber plane, it is characterized in that: cutter hub is cylindric, and the post center is a manhole, cuts etc. dark, equidistant on the face of cylinder and perpendicular to the rectangle groove of cutter hub axis; Along several uniform hand of helixs of being separated by, to end blade is installed equidistantly by origin or beginning;
