The specific embodiment
With reference to Figure of description 1 is the vertical profile structural representation according to a kind of deep hole processing cutter of the present invention; Met the preferable implementation that the present invention adopted, those skilled in the art can select or flexible correlation technique means according to the description about preferable examples.The title of the technological means that adopts does not constitute the concrete qualification to its structure in the example, and relevant technological means should be fallen within protection scope of the present invention by simple transformation.
A kind of deep hole processing cutter is shown in the Figure of description 1; As existing deep hole processing cutter with harmomegathus function, it has the cutter hub 14 that comprises tubulose, certainly; Cutter hub is not strict cylindrical tube; Because of there are many syndetons on its surface, mainly be that axial hole is contained at its center, form a sleeve structure.
In cutter hub 14 direct perhaps indirect assembly heavy boring portion, scraping portion and roll extrusion portion are arranged, form machining functions portion.
Wherein:
Heavy boring portion turnover size is minimum, is used for heavy boring processing, is fitted in the cutter head end, i.e. left end among Fig. 1, and the other end is the seat end of cutter, is used to connect boring bar.This part does not need harmomegathus usually, and cutting force is also bigger, if dispose the harmomegathus structure, can influence the precision of heavy boring, and is unfavorable to following process yet.
The heavy boring blade 39 of heavy boring portion is equipped with 3 usually, is uniformly distributed with to be installed on the heavy boring cutter hub 4, in order to improve heavy boring dynamic stiffness partly; Axial symmetry side at heavy boring blade 39 is provided with guiding strong 6; Form supplemental support, can improve dynamic stiffness, and then improve the precision of processing.
Operation after the heavy boring generally is right boring, therefore, in gang tool, scrapes sharpener by assembly.
As shown in Figure 1, scraping portion is installed on the cutter hub 14 of rear side of heavy boring portion.Known, for weight reduction, compound tool is processed to the structure of hollow usually, and the part of hollow can be installed other annexes.
Referring to Figure of description 3, be the A-A sectional structure sketch map of accompanying drawing 1.In order clearly to express key points in design, omit incoherent part, be mainly used in and express the mounting structure of scraping sharpener.
A scraping body 34 has some radial holes among Fig. 3, and scraping 34 is directed in the radial hole of being installed, and entad holds restrainedly, is in the stable state of work.
In order to satisfy the harmomegathus of scraping part, a jacking block 5 is configured in the entad end of scraping 34, and engages.Corresponding engagement portion has first gradient, realizes the scraping depth of cut of scraping head through the variation of jacking block 5 positions.Have simultaneously can big accompanying drawing the driving jacking block, make scraping 34 break away from surface of the work fully, be in the withdrawing state, this also is the general structure of known harmomegathus structure.
After the fine finishining the 3rd step is roll extrusion, adopts roller 11 as illustrated in fig. 1 and 2, is similar to the bearing arrangement of an opening, is analogous to the outer ring of bearing by the workpiece of roll extrusion.Among Fig. 2, roller is held frame 20 and constrains in uniformly on the raceway 12, forms uniform roll extrusion, the load basically identical that each roller 11 is suffered.
The side of raceway is a centrum, certainly, can form groove in groove portion, and groove has constant slope, is second gradient.Axial at cutter hub 14 so, roller is driven, and just can realize the harmomegathus of roll extrusion portion.
Harmomegathus has two purposes, and one is the adjustment depth of cut, and another then is a withdrawing, need keep Stability Analysis of Structures during feed, and withdrawing then requires action fast.
The configuration mode of harmomegathus has been well known in the art, and among Fig. 1, retainer 13 also is connected on the push rod 32, can realize harmomegathus fast with the synchronous fast driving of jacking block 5, satisfies the needs of withdrawing.Different because of working method, the direction of first gradient and second gradient is different, in fact, has the people of physics general knowledge all to dispose the version of gradient in different application in view of the above easily slightly.
In the cutter hub 14 is the operating space, also is the installation control of adjustment component such as push rod.
In Fig. 1, said push rod 14 and said jacking block 5 threaded engagement form the screw thread pair that jacking block moves about, and so, accordingly, push rod is by the constraint of seat portion, and its structure can be with reference to the screw lead screw pair, and the technical staff of mechanical field realizes according to this structure easily.
Thereby; In addition corresponding; If making jacking block 5 position changes, a kind of mode of operation is first manner of execution that drives push rod 14 actions, another kind of mode then is second kind of manner of execution of the said seat of driving portion action; This programme is chosen as the adjustment that first manner of execution is used to scrape sharpener, and second kind of manner of execution is used to scrape the withdrawing of sharpener.
Withdrawing needs and resets, and preferably adopts the resetting means fixedly install to reset, and is restrained at the axial end of cutter hub in the axially movable free degree of cutter hub like seat portion, the other end device constraint that is reset.The reseting precision of this structure is than higher.Also can adopt additional device to carry out the adjustment of two dead points, like cylinder, but this structure can increase the complexity of structure, does not advocate use.
As shown in Figure 1, said driving link is one to have the knob 1 of centre bore, correspondingly; The cutter head end of said push rod 32 is the multiple edge body structure, by the empty section geometric said centre bore similar that be inserted in this multiple edge body part section, thereby; In the multiple edge body part, push rod 32 has in the axially movable free degree of centre bore, the setting of convenient quick harmomegathus structure; Have the characteristics of axial times of centre bore constraint simultaneously, satisfy rotation, realize that the structure of harmomegathus realizes at a slow speed through knob 1.
In order to make the Stability Analysis of Structures of duty; Knob 1 is axially arranged with holding screw at cutter hub, and screw 11 as shown in Figure 1, this holding screw hold heavy boring portion front end face; And the lockup state of formation knob; The free degree is restrained in relative rotation to make push rod, and certainly, the free degree of following the cutter rotation does not have restrained.
Among the figure, knob 1 is installed in the heavy boring head through revolute pair, and for this reason, knob itself can be common handwheel structure, and convenient adjustment can be provided with rear sight at correspondence position, and adjustment does not need to calculate again easily and fast.
Because be manual adjustment, so, rear sight is set as much as possible, do not need to carry out again additional calculation.
Preferably, said multiple edge body structure and said centre bore matched in clearance had both satisfied the needs of quick harmomegathus, satisfied the needs of adjustment precision again.
The automatic harmomegathus gang tool that occurs in recent years, the mode that adopts fine boring cutter to float is processed, and is easy to generate the vibrations line; For this reason, the configuration guide pad is with the minimizing vibrations line that floating boring tool was produced, but guide pad is easy to wear; Cause the cutter support force not enough, directly influence working (machining) efficiency and machining accuracy.
Guide pad 8 except service wear; Also be embodied in the accelerated wear test in the rapid return, for this reason, a kind of preferable selection is; A scraping body 34 of said scraping portion circumferentially is being evenly equipped with the even number radial hole; And the compartment of terrain installs said scraping 36, and all the other radial holes then are used to guide pad 8 is set, and the entad end of guide pad also engages with the composition surface that said jacking block 5 has first gradient.
Guide pad 8 materials adopt the big nylon of elastic modelling quantity, are that the guide pad diameter dimension guarantees needed support force in the process greater than actual processing dimension 0.2～0.3mm through interference fit.
In structure shown in Figure 3, radial hole has six, and guide pad 8 and scraping 36 each 3 certainly, according to the size of scraping part, increase the number of guide pad and scraping head.
Guide pad 8 is notions; The funtion part of in Fig. 2 and Fig. 1, having represented the scraping piece; The part that just contacts with surface of the work, the guide pad have here comprised the guide pad body that is used to install it, are illustrated in to be guiding block 7 among Fig. 1 and Fig. 2; Can change guide pad eaily, and be whole scrapping.
In Fig. 1; Gradient is raceway 12 even 8～16 rollers 11 that distribute on circumference of 2 °; Number is that the roller quantity of even number is according to the size of cutter and difference; Roller 11 is placed in the groove of retainer 31 and restrained, and the knob 27 that has graduation mark is connected with pulling block 16 through screw thread, and pulling block is connected with retainer 31 with nut 30 through bearing then.Retainer 13 is fixed together through screw 29 and retainer 31, and rotation knob 27 promotes to move axially on raceway 12 through roller 11, thereby reaches the purpose of adjustment roll extrusion size.Be processed with on the knob 27 and be used to rely on the groove of self-deformation locking usefulness and the counterbore and the screwed hole of mounting screw 15 usefulness.After adjustment finishes, tighten screw 15, guarantee process roll extrusion dimensionally stable.
Roll extrusion is in order to improve bore area hardness, wearability and reduction surface roughness.Roller is made into three sections circular cones, and through the appropriate design to the roller shape and size, when squish area increased as far as possible, the extruding force that acts on the roller distributed as far as possible rationally the life-span that so just helps improving roller.
Among Fig. 1, push rod engages with blind rivet 17, is convenient to whole by fast driving.
Tail end at cutter is provided with supplemental support portion, and this supplemental support portion is a set type structure, and outer peripheral face is provided with wear-resisting nylon block 20; The supplemental support cutter so long as play a supportive role during withdrawing, is installed on the cutter hub 14 through screw; Scratch surface of the work in the time of can effectively preventing to lose the cutter withdrawing of end portion, supports, simultaneously, this part is that cutter provides a support; Improve integral rigidity, and then improve machining accuracy.
