Abstract
The utility model relates to a drill jig chamfer counter bit. A cutting part is arranged at the front end of a counter bit tail rod, the cutting part is formed by two chamfered teeth and two counter boring teeth, wherein the chamfered teeth and the counter boring teeth are circularly distributed in a crossed mode based on an axis serving as a center. The drill jig chamfer counter bit not only is simple in structure, but also can carry out counter sinking and 45-degree-angle chamfering at the same time, therefore reduces machining procedures, greatly improves production efficiency, and guarantees quality of products.
Description
Technical field
The utility model relates to a kind of drill jig chamfering counterbit, belongs to a kind of machine tools, is used for the operation of processing spot-facing and 1 * 45 ° of chamfering of chamfering.
Background technology
In machining, processing for the hole, we can often use counterbit, the type that counterbit is commonly used comprises: 60 °, 90 °, 120 ° of staight shank taper countersinks, 60 °, 90 °, 120 ° of Morse taper shank counterbits, be with whole guide pillar staight shank counterbore, be with interchangeable guide pillar Morse taper shank counterbore, be with 90 ° of taper countersinks of whole guide pillar staight shank, be with 90 ° of taper countersinks of interchangeable Morse taper shank, scabble type staight shank counterbit, Morse taper shank counterbit, cylinder quick change handle counterbit, but for aviation field, busy counter boring and the chamfering of needing machines together, all is to adopt counter boring to bore with the chamfering counterbit to be used in the past, just can reach the needs of production.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of drill jig chamfering counterbit, this drill jig chamfering counterbit is not only simple in structure, and can carry out spot-facing simultaneously and can fall the operation of 45, thereby has reduced manufacturing procedure, greatly improve production efficiency, guaranteed the quality of product.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of drill jig chamfering counterbit, front end at the counterbit foot piece is provided with cutting tip, and cutting tip is made up of two chamfered teeths and two spot-facing teeth, chamfered teeth and spot-facing tooth circumference cross-distribution centered by axis.
The middle part of described counterbit foot piece is provided with stop, and the outside of stop is provided with stop nut.
This drill jig chamfering counterbit adopts two chamfered teeths and two spot-facing toothings, can carry out the processing of 1 * 45 ° of chamfering in spot-facing, has reduced the usage quantity of cutter, reduces cost, reduces manufacturing procedure, has improved operating efficiency.Adopted stop and stop nut simultaneously, can guarantee axial displacement, thereby effectively the counter boring degree of depth has been controlled.
