Abstract
The utility model provides a special drilling reamer for the casing of an automobile air conditioner, which is used for machining an installation hole with the inner wall thereof to be stepped and the machined installation hole is high in concentricity and good in precision. The special drilling reamer comprises a handle part and a working unit integrally formed with the handle part. The working unit comprises a drill bit arranged at an axial end, and a spiral chip discharge groove arranged circumferentially. The special drilling reamer is characterized in that the working unit is also provided with a step end milling cutter and an arc milling cutter. The step end milling cutter, the arc milling cutter and the handle part are coaxially arranged. The diameter of the drill bit is smaller than the diameters of the step end milling cutter and the arc milling cutter. Since the working unit of the handle part is simultaneously provided with the drill bit, the step end milling cutter and the arc milling cutter, the machining concentricity and precision of an installation hole in the casing of an automobile air conditioner can be ensured at utmost. The production mechanization is improved and the time for replacing different cutters is saved to a certain extent. Meanwhile, the production efficiency is improved and the cost is saved.
Description
Technical field
The utility model relates to a kind of drilling reamer, especially a kind of special jewel reamer of motorcar air conditioner casing.
Background technology
At present; Automobile on the market all is equipped with motorcar air conditioner, improves Che Nei driver and passenger's comfort level with this, can offer corresponding installing hole on this type of motorcar air conditioner casing; This installing hole is a blind hole; Be provided with a plurality of stair-stepping annular round platforms in the installing hole, and parts such as spring, securing member and keeper are installed in the installing hole, and then satisfy the needs such as fixing, location and buffering protection of motorcar air conditioner.Because the internal structure of this installing hole is comparatively complicated; So the processing method of this installing hole also need manyly cooperate cutter could realize; At first get out corresponding pass through drill bit; In the hole of institute's moulding, mill out the step of a plurality of annulars to different milling cutters through many then, and the step that is milled out is carried out finish-milling.But; When using different cutters, needs add man-hour; Then will change, locate mounted cutter, the cutter after so just possibly occurring changing can not keep fully with one heart, thereby makes that the installing hole aperture that processes is either large or small; Perhaps depart from self axial position, make troubles for corresponding component is installed.
Summary of the invention
In order to overcome the deficiency of prior art, it is step-like installing hole that the utility model provides a kind of inwall of processing, and makes this installing hole concentricity high, the special jewel reamer of the motorcar air conditioner casing that precision is good.
The utility model solves the technical scheme that its technical problem adopted: a kind of special jewel reamer of motorcar air conditioner casing; Comprise that shank reaches and the integrated working portion of this shank; This working portion includes the drill bit that axial end is provided with; And helical flute circumferentially is set, it is characterized in that: also be provided with step slotting cutter and arc cutter with the coaxial setting of shank on the said working portion, the diameter of said drill bit is less than the diameter of step slotting cutter and arc cutter.
Further being set to of the utility model: the adjacent setting of said step slotting cutter with drill bit, the adjacent setting of said arc cutter with the step slotting cutter, and arc cutter axially is provided with around working portion, and the step slotting cutter is between drill bit and arc cutter.
Further being set to of the utility model: said step slotting cutter includes the little milling cutter of adjacent successively and coaxial setting, middle milling cutter and big milling cutter; The diameter of little milling cutter, middle milling cutter and big milling cutter increases successively; Little milling cutter and drill bit are adjacent, and big milling cutter is adjacent with arc cutter.
Further being set to again of the utility model: through the chamfered transition setting, be provided with through the arc surface transition between middle milling cutter and big milling cutter between said little milling cutter and middle milling cutter.
The beneficial effect of the utility model is: earlier through bit bore, little milling cutter, middle milling cutter and big milling cutter be respectively along with the preceding of drilling reamer and then get out different steps, and under the processing of arc cutter, further obtain the precision height, fineness good installing hole.Working portion at shank is provided with drill bit, step slotting cutter and arc cutter simultaneously; Thereby the concentricity and the precision of installing hole processing on the motorcar air conditioner casing can have been guaranteed to the full extent; Improve the mechanization of producing; And saved time of better different cutters to a certain extent, and then improved production efficiency, practiced thrift cost.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the sketch map of the utility model embodiment.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2; Present embodiment comprises that shank 1 reaches and this shank 1 integrated working portion 2; This working portion 2 includes the drill bit 21 that axial end is provided with; With the step slotting cutter 22 and arc cutter 23 of shank 1 coaxial setting, and helical flute 24 is set circumferentially, the diameter of said drill bit 21 is less than the diameter of step slotting cutter 22 and arc cutter 23.Wherein, Said step slotting cutter 22 and drill bit 21 adjacent settings, said arc cutter 23 and the 22 adjacent settings of step slotting cutter, and arc cutter 23 axially is provided with around working portion 2; Step slotting cutter 22 is between drill bit 21 and arc cutter 23; The working face of arc cutter 23 from drill bit 21 parts extend on the working portion 2 always than drill bit 21 parts than far-end, and whole process is all for seamlessly transitting, the inwall precision that then processes is also higher.Said step slotting cutter 22 includes little milling cutter 221, middle milling cutter 222 and the big milling cutter 223 of adjacent successively and coaxial setting; The diameter of little milling cutter 221, middle milling cutter 222 and big milling cutter 223 increases successively; Little milling cutter 221 is adjacent with drill bit 21, and big milling cutter 223 is adjacent with arc cutter 23.In addition, 222 on said little milling cutter 221 and middle milling cutter pass through the chamfered transition setting, and middle milling cutter 222 and 223 on big milling cutter pass through arc surface transition setting.
In the utility model, earlier through drill bit 21 borings, little milling cutter 221, middle milling cutter 222 and big milling cutter 223 be respectively along with the preceding of drilling reamer and then get out different steps, and under the processing of arc cutter 23, further obtain the precision height, fineness good installing hole.Working portion 2 at shank 1 is provided with drill bit 21, step slotting cutter 22 and arc cutter 23 simultaneously; Thereby the concentricity and the precision of installing hole processing on the motorcar air conditioner casing can have been guaranteed to the full extent; Improve the mechanization of producing; And saved time of better different cutters to a certain extent, and then improved production efficiency, practiced thrift cost.The utility model can also have other embodiments, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the scope of the utility model requirement protection.
