Abstract

The utility model relates to a taper hole cutter used for preparing taper holes and comprising a conical head (1.1), a screw blade (1.2) and a knife handle (1.3), wherein the screw blade (1.2) is arranged on the circumference of the outer surface of the conical head (1.1); and the conical head (1.1) is fixedly connected with one end of the knife handle (1.3). Due to the adoption of common radial drill operation, the taper hole cutter does not need an expensive numerical control machine, thus greatly reducing processing cost; the spiral cutter has quite stable cutting in the hole; and the processing precision and size are easy to control.

Description

The taper hole cutter

(1) technical field

The utility model relates to a kind of cutter, and especially a kind of taper hole cutter is used for the making of taper hole, belongs to the steel construction manufacture field.

(2) background technology

At present, on the steel construction workpiece, often need process the taper hole structure, now the method that generally adopts is to utilize Digit Control Machine Tool that workpiece is processed, but there is the high problem of processing charges, simultaneously, for large-sized steel construction piece, need customize specific board toward contact it is processed, further increased the expense of processing.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of taper hole cutter that can use common radial drill processing taper hole, so that cut down finished cost.

The purpose of this utility model is achieved in that a kind of taper hole cutter, includes conehead, screw blade and handle of a knife; Described screw blade is arranged on the outer surface circumference of conehead, and described conehead is fixedlyed connected with handle of a knife one end.

The beneficial effects of the utility model are: owing to use common radial drill operation, do not need to use expensive Digit Control Machine Tool, greatly reduce processing cost, and helical tooth blade cuts quite steadily in the hole, machining accuracy and size are easy to control.

(4) description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the taper hole structural representation.

Fig. 3 is taper hole processing schematic diagram.

Fig. 4 is the utility model taper hole cutter user mode schematic diagram.

Among the figure: conehead 1.1, screw blade 1.2, handle of a knife 1.3, steel construction workpiece 2, taper hole 2.1, the first circular holes 2.2, the second circular holes 2.3, unnecessary leftover pieces 1, unnecessary leftover pieces 2 2.5.

(5) specific embodiment

Referring to Fig. 1, the utility model relates to a kind of taper hole cutter, includes conehead 1.1, screw blade 1.2 and handle of a knife 1.3; Described screw blade 1.2 is arranged on the outer surface circumference of conehead 1.1, and described conehead 1.1 is fixedlyed connected with handle of a knife 1.3 1 ends.

Referring to Fig. 2, Fig. 3 and Fig. 4, add man-hour, use common drill bit successively to process first circular hole 2.2 and second circular hole 2.3 earlier in 2 required processing place of steel construction workpiece, conehead 1.1 with the taper hole cutter probes in second circular hole 2.3 then, rotation handle of a knife 1.3 and then 1.1 rotations of drive conehead, unnecessary leftover pieces 1 and unnecessary leftover pieces 2 2.5 remaining when the screw blade 1.2 that is provided with on conehead 1.1 outer surfaces just will be processed first circular hole 2.2 and second circular hole 2.3 scrape off, and just form the taper hole 2.1 that meets standard among Fig. 3.

Claims

1. taper hole cutter, it is characterized in that: described cutter includes conehead (1.1), screw blade (1.2) and handle of a knife (1.3); Described screw blade (1.2) is arranged on the outer surface circumference of conehead (1.1), and described conehead (1.1) is fixedlyed connected with handle of a knife (1.3) one ends.
