Abstract

The utility model provides a taper-hole processing cutter, and belongs to machine cutting tools. The taper-hole processing cutter comprises a cutter head, a cutter seat and a cutter handle, wherein, the cutter seat is not perpendicular to the cutter handle; the included angle of axes of the cutter seat and the cutter handle is an acute angle; the cutter seat is fixedly connected with one end of the cutter handle; and the cutter head is fixed on the cutter seat. The taper-hole processing cutter is operated by using a common lathe, and an expensive numerical control lathe has no need to be used, so that the processing cost is greatly reduced; and besides, the spiral cutter is quite steady when cutting the inner part of a hole, so that the processing precision and the size are easy to control.

Description

A kind of taper hole process tool

Technical field

The utility model relates to a kind of cutter, a kind of specifically taper hole process tool.

Background technology

Cutter is the important tool of machine cut processing.At present; On the steel construction workpiece, often need process the taper hole structure, the existing method that generally adopts is to utilize Digit Control Machine Tool that workpiece is processed, but has 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.

Summary of the invention

In view of the defective that prior art exists, the purpose of the utility model is a kind of cutter will be provided, and the processing taper hole is so that cut down finished cost.

For realizing above-mentioned purpose, the utility model provides a kind of taper hole process tool, it is characterized in that: cutter; Include cutter head, tool rest and handle of a knife, tool rest and handle of a knife are non-perpendicular, and both axis angles are acute angle; Said tool rest is fixedly connected with handle of a knife one end, and cutter head is fixed on the tool rest.

The beneficial effect of the utility model is: owing to use the engine lathe operation, need not 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.

Fig. 1 is the utility model structural representation.

Fig. 2 is the taper hole structural representation.

Fig. 3 is taper hole processing sketch map.

Fig. 4 is the utility model taper hole cutter user mode sketch map.

Among the figure: cutter head 1.3, tool rest 1.2, handle of a knife 1.1, 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.

The specific embodiment

For understanding a kind of taper hole process tool in depth, explain as follows in conjunction with Fig. 1 to Fig. 4:

A kind of taper hole cutter includes cutter head 1.3, tool rest 1.2 and handle of a knife 1.1, and tool rest 1.2 is non-perpendicular with handle of a knife 1.1, and both axis angles are 15 °, and said tool rest 1.2 is fixedly connected with handle of a knife one end, and cutter head 1.3 is fixed on the tool rest.

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; Cutter head 1.3 with the taper hole cutter probes in second circular hole 2. 3 then; Handle of a knife 1.1 and then 1.3 rotations of drive cutter head are cut on cutter head 1.3 outer surfaces, just will process 2. 3 o'clock remaining unnecessary leftover pieces 1 of first circular hole 2. 2 and second circular hole and scrape off with unnecessary leftover pieces 2 2. 5; Just form Fig. 3, the workpiece taper hole gradient is 15 °.

Claims
