Abstract
The utility model discloses a self -align flat rimer, including cutter arbor, handle of a knife, the cutter arbor have preceding tip and have the blade holder with back tip, preceding tip week side equipartition, install the blade on the blade holder, back tip and handle of a knife middle part be connected through being equipped with the pilot taper, pilot taper opposite flank axis be 90 degrees contained angles, preceding end connection have cylindrical one end, the cylindrical other end is the direction cylinder of toper shape. The utility model discloses having added a direction cylinder and pilot taper in front at flat rimer, having made flat rimer when processing nodular cast iron, direction cylinder and pilot taper form the ladder of a transitionality, and is during the flat processing blank plane of ream, more steady to planar size of a dimension has been guaranteed.
Description
Technical field
The utility model belongs to auto parts and components machined field, relates to a kind of flat counterbit, specifically a kind of self-align flat counterbit for processing spheroidal graphite cast-iron.
Background technology
Counterbit carries out the processing of plane, cylinder, the conical surface and other profiles to the end face in hole.On the hole processed when processing column shape counter sink, taper counter sink and end face boss, all use counterbit.Its circumference of counterbore and end face respectively have 3-4 cutter tooth, in manufactured hole, inserts guide pillar, it act as the coaxiality error controlled by spot-facing and original hole.
Above-mentioned existing counterbore is when processing spheroidal graphite cast-iron, and guide pillar plane does not have stairstepping, adds spheroidal graphite cast-iron self material qualitative factor, causes in process, and have displacement, not steady phenomenon, make processing dimension inaccuracy, the size of plane has error.Now for above-mentioned produced problem, provide a kind of technical scheme of improvement.
Utility model content
The purpose of this utility model is to overcome prior art deficiency, provides a kind of self-align flat counterbit.
The purpose of this utility model can be achieved through the following technical solutions:
Self-align flat counterbit, comprises knife bar, handle of a knife, and described knife bar has leading section and rearward end, all sides, leading section are evenly equipped with tool rest, tool rest is provided with blade, and described rearward end is bored with in the middle part of handle of a knife be connected by being provided with transition, and described transition cone opposite flank axis is 90 degree of angles; Described leading section is connected with one end of cylinder, and the other end of cylinder is the guide cylinder of conical by its shape.
The diameter that joint face is bored in described rearward end and transition is less than the diameter of transition cone and handle of a knife joint face.
Described tool rest is provided with four, and corresponding blade also has four, and the axis angle of adjacent tool rest and blade is 75 degree, and tool rest and guide cylinder axis angle are 10 degree.
The beneficial effects of the utility model: the utility model has added a guide cylinder and transition cone before flat counterbit, make flat counterbit when processing spheroidal graphite cast-iron, guide cylinder becomes a cambic ladder with transition taper, during the flat machining blanks plane of ream, more steady, and ensure that the size of plane.
Accompanying drawing explanation
The utility model to be further described below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that.
Fig. 1 is the utility model front elevational schematic;
Fig. 2 is the utility model schematic side view
Detailed description of the invention
As depicted in figs. 1 and 2, self-align flat counterbit, comprise knife bar 1, handle of a knife 2 and connect knife bar 1 and bore 3 with the transition of handle of a knife 2, it is 90 degree of angles that 3 opposite flank axis are bored in transition, handle of a knife 2 is that No. 4 Morse's tapers are arranged, knife bar 1 has leading section 4 and rearward end 5,4 weeks sides, leading section are evenly equipped with the tool rest 6 of tungsten-cobalt alloy material, tool rest 6 is provided with blade 7, tool rest 6 is provided with four, corresponding blade 7 also has four, and the axis angle of adjacent tool rest and blade is 75 degree, and tool rest and guide cylinder axis angle are 10 degree.The diameter of rearward end 5 is less than leading section 4 diameter, and rearward end 5 and transition are bored 3 and be connected, and leading section 4 is connected with cylinder, and the middle part being positioned at cylinder week side is provided with strengthens cylinder 9, and cylinder front end is provided with the guide cylinder 8 of a taper.In Fig. 1, handle of a knife 2 other end is installation portion 10, and handle of a knife 2 runs through workpiece.Owing to having added a guide cylinder 8 and transition before flat counterbit, to bore 3 opposite flank axis be 90 degree of angles, make flat counterbit when processing spheroidal graphite cast-iron, guide cylinder 8 and transition are bored 3 and are formed a cambic ladder, during the flat machining blanks plane of ream, more steady, there will not be offset phenomena, ensure that the size of plane.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
