Abstract
The utility model relates to the technical field of processing cutters, in particular to an integral cutter of a combined-type counter bit, which comprises a cutter arbor and a cutter bit, wherein the cutter bit comprises countersinks and a drill bit; the countersinks are fixedly connected to the front end of a socket drill; the drill bit is fixedly connected into the socket drill; the socket drill is in movable threaded connection with the cutter arbor through a retaining nut; the countersinks are at least two pieces of uniformly distributed blades; and the socket drill can adjust the length of the cutter bit relative to the cutter arbor through a nut at an end part. The integral cutter has the advantages that 1, a central hole and an end surface are processed and formed in one step, so as to ensure the dimensional precision and the form and position tolerance; 2, time required for processing and replacing a cutter can be shortened, so as to improve the production efficiency; and 3, the socket drill is convenient and fast to disassemble and assemble, and high in exchangeability.
Description
Technical field
The utility model relates to the process tool technical field, specifically is meant a kind of combined type counterbit one cutter.
Background technology
Prior art is when processing excircles and chamfer machining; Particularly during shaft element; General clamped cutting bit sheet processing excircles and the planar end surface of adopting used the centre drill centering again, because high rhythm and high benefit all are particular about by present enterprise; Therefore the multiplicity to cutter proposes increasingly high requirement, and the traditional processing process is difficult to satisfy its instructions for use.
The applicant utilizes its professional eye and professional knowledge because the disappearance and the inconvenience of above-mentioned convention process tool are being adhered to the spirit that research is innovated, kept on improving, and works out a kind of combined type counterbit one cutter.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of combined type counterbit one cutter is provided, simultaneously ream planar end surface and drill centers.
The technology of the utility model does, comprises knife bar and cutter head, and said cutter head comprises countersink and drill bit;
Said countersink is fixed in the front end that cover bores;
Said drill bit is fixed in the inside that cover bores;
Said cover drilled through the retainer nut and the knife bar screw thread flexibly connects.
Said countersink is at least two blades that are uniformly distributed with.
Said cover bores the length dimension that can regulate the relative knife bar of cutter head through the nut at position, termination.
The advantage of the utility model comprises that 1. centre bore and the moulding of end face time processing have guaranteed dimensional accuracy and form and position tolerance; 2. shorten processing and changed the required time of cutter, improved production efficiency; And cover bore easy accessibility, quick, interchangeability is good.

Fig. 1 is the utility model cutaway view.
Fig. 2 is the utility model front view.
Fig. 3 is a process flow diagram.
The specific embodiment
Preferred embodiment below in conjunction with 1 to 2 pair of the utility model of accompanying drawing is described further, and the utility model comprises knife bar 4 and cutter head 1, and said cutter head 1 comprises countersink 11 and drill bit 12;
Said countersink 11 is welded in cover and bores 2 front end;
Said drill bit 12 is welded in the inside of cover brill 2;
Said cover bores 2 through retainer nut 3 and the flexible connection of knife bar 4 screw threads.
Said countersink 11 is four blades that are uniformly distributed with.
Said cover brill 2 can be regulated the length dimension of cutter heads 1 relative knife bar 4 through the nut 5 at position, termination.
During assembling, overlap brill 2 and be set on the knife bar 4, the position through cover bores the nut 5 regulating sleeves brill 2 relative knife bars 4 at position, 2 termination after length dimension regulates, through two retainer nuts 3 that screw, reaches the effect of adapter sleeve brill 2 and knife bar 4.
Processing technology is shown in accompanying drawing 3, and the first step moves to plane to be processed through anchor clamps with knife bar 4, and knife bar 4 drives cutter 1 rotation, and promptly countersink 11 rotates with drill bit 12 simultaneously; In second step, knife bar 4 drives cutter head 1 and advances along machine direction, countersink 11 spot facings and drill bit 12 machining center holes, and in the 3rd step, knife bar 4 drives cutter head 1 and oppositely withdraws from along machine direction.
The utility model not only will satisfy client's product size requirement, has broken traditional processing technology in use, has shortened processing and has changed the required time of cutter, has realized the innovation of technology, has improved production efficiency.
The above embodiment has only expressed a kind of embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
