The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As shown in Figure 4, the utility model staged boring cutter comprises a boring cutter cutter hub 1 and a boring cutter bar 2, and boring cutter bar 2 is arranged on the boring cutter cutter hub 1, and boring cutter bar 2 comprises several round platforms.Said round platform is pressed diameter and is formed notch cuttype by big extremely little outside stack, and the outer edge of the upper end of each said round platform is provided with a cutter head.
Wherein, the notch cuttype of boring cutter bar 2 with need the product processed form fit, and different cutter heads are set on different round platforms, thereby realize that once heavy boring is cut and reboring.Different cutter heads are arranged according to manufacturing procedure and are installed on the boring cutter bar 2, can realize disposable completion whole machining process operation, have reduced the requirement to equipment precision.Preferably, said cutter head successively ecto-entad be a heavy boring cutter head 21, a right boring cutter head 22 and a counterbore cutter head 23.
In addition, the aperture size that the tactical diameter of heavy boring cutter head 21 will equal to be processed deducts right boring surplus (the right boring surplus is confirmed by 0.6-0.8mm), and the tactical diameter of right boring cutter head 22 and counterbore cutter head 23 is confirmed according to the shoulder hole size of reality processing.Distance between heavy boring cutter head 21, right boring cutter head 22 and the counterbore cutter head 23 is greater than the 1-2mm of working depth size, and operation is accomplished with the back operation and separated before being convenient to, and avoids mutual interference phenomenon, guarantees the precision in the aperture that processes.
Be provided with in the rear end of right boring cutter head 22 one have one regulate bolt micro-adjusting mechanism 24.Through regulating the position of bolt front and back adjustment right boring cutter head 22, its use is flexible.
In addition, below heavy boring cutter head 21 and counterbore cutter head 23, be respectively equipped with a chamfering cutter head 25, be located at the outer edge of the lower end of corresponding said round platform.Adopt 25 pairs of hole inwalls of chamfering cutter head to carry out chamfered, can be so that the hole be slick and sly more attractive in appearance.
Further, heavy boring cutter head 21, right boring cutter head 22 and counterbore cutter head 23 are positioned at the front of corresponding said round platform, and then chamfering cutter head 25 is positioned at the reverse side of corresponding said round platform.This structure can guarantee the chamfering step immediately following after heavy boring is cut and after the reboring, and it is smooth and easy to make that whole operation links up, and effectively saves the non-cutting time of process.
In addition, chamfering cutter head 25 and above-mentioned other cutter heads that adopt are all through bolt, and said cutter head is circular, square or triangle.Certainly, above-mentioned all cutter heads can also adopt other fixed forms, and the shape of said cutter head also can be confirmed according to the shape and the procedure of processing of actual shoulder hole.
Before using the bore hole of the utility model processing shoulder hole, must test affirmation to each dimensional accuracy of boring cutter earlier.Need therebetween to try boring processing, and the requirement surplus of being processed is identical with actual product institute made allowance with a product or with the workpiece of same thickness same material.The aperture that processes and the aperture and the depth dimensions of shoulder hole are surveyed.Adjusting bolt through on the micro-adjusting mechanism 24 is adjusted the precision of datum hole, and the boring cutter of adjusting is tried processing again, guarantees that its precision is controlled within the dimensional requirement.Then, the adjusting bolt on the locking micro-adjusting mechanism 24 prepares to get into formal processing.
Shown in Fig. 5-7, formal process mainly comprises three steps.At first, with heavy boring cutter head 21 fast feeds on the boring cutter bar 2 to apart from cutting point 1-2mm place.Select suitable cutting commentaries on classics degree and feed speed that shoulder hole is carried out roughing, chamfering cutter head 25 follows heavy boring cutter head 21 closely and accomplishes the chamfering process in ladder aperture afterwards simultaneously.After heavy boring cutter head 21 was accomplished product roughing, cutter hub continued the feeding sky and walks 1-2mm (as shown in Figure 5).Then, heavy boring cutter head 21 leaves machined surface, and right boring cutter head 22 begins shoulder hole is carried out fine finishining.After fine finishining was accomplished, right boring cutter head 22 continued the feeding sky and walks 1-2mm (as shown in Figure 6).Then, 23 pairs of shoulder holes of counterbore cutter head are processed.When the counterbore deep processing put in place, chamfering cutter head 25 was accomplished the chamfering process (as shown in Figure 7) in ladder aperture simultaneously.So far all processes of processing finishes, and the main shaft boring cutter cutter hub that shuts down makes zero fast, accomplishes a process-cycle.
To sum up; The utility model staged boring cutter is after the heavy boring cutter head machines and leaves machined surface; The hole wall that the right boring cutter head is crossed heavy boring again carries out right boring processing, avoiding the irregular heavy boring cutter hub that is caused of black skin unstable, and influences the precision of right boring.The counterbore cutter head was processed shoulder hole again after right boring was accomplished.The purpose of substep processing is when preventing the cutting of multitool sword, stressed difference between each blade and the boring cutter bar shake that produces causes trueness error.Boring cutter is disposable after all machining withdraws from.Whole process need not withdrawing and tool changing, has significantly reduced non-cutting time, uses more conveniently, and efficient is higher.
Though more than described the specific embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
