Detailed description of the invention

For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

The sectional drawing of the Hob fixing device of the development machine cutterhead that Fig. 1 provides for the utility model embodiment; The structural representation of tool rest in the Hob fixing device of the development machine cutterhead that Fig. 2 a provides for the utility model embodiment; Fig. 2 b is the upward view of Fig. 2 a; Fig. 2 c is the top view of Fig. 2 a.

See figures.1.and.2 a-Fig. 2 c, and the Hob fixing device of the described development machine cutterhead that the present embodiment provides specifically can comprise: tool rest 102, cutter shaft 103 and fixation kit; Described fixation kit comprises voussoir 104, bolt 105, briquetting 106 and nut 107.

Wherein, described tool rest 102 is welded on described cutterhead, described cutter shaft 103 and the clamping of described tool rest 102 phase; Described voussoir 104 is connected between described tool rest 102 and described cutter shaft 103; Described briquetting 106 is pressed on described voussoir 104, and described bolt 105 successively through described briquetting 106 and described voussoir 104, and is tightened by described nut 107, is fastened on described tool rest 102 by described cutter shaft 103.

Concrete, the structure of described tool rest 102 can with reference to Fig. 2 a-Fig. 2 c, and one end of described tool rest 102 is provided with LJ shape notch, and described LJ shape notch is made up of L shape two-dimensional direct edged surface and J-shaped face; One end of described cutter shaft 103 is L shape two-dimensional direct edged surface; The other end of described cutter shaft 103 is inclined-plane, and described voussoir 104 is right-angled trapezium.

In practical application, described cutter shaft 103 is specially with the clamping of described tool rest 102 phase: when described cutter shaft 103 is with described tool rest 102 phase clamping, the L shape two-dimensional direct edged surface of described cutter shaft 103 matches with the L shape two-dimensional direct edged surface of described tool rest 102.Described voussoir 104 is connected between described tool rest 102 and described cutter shaft 103 and is specially: the plane at the waist place, right angle of described voussoir 104 matches with the J-shaped face of described tool rest 102; The plane at the hypotenuse waist place of described voussoir 104 matches with the inclined-plane of described cutter shaft 103.

Described voussoir 104 can be found out in FIG for right-angled trapezium, between the inclined-plane that described voussoir 104 embeds described cutter shaft 103 and the J profile of described tool rest 102, described briquetting 106 is pressed on described voussoir 104, described bolt 105 is successively through described briquetting 106 and described voussoir 104, and tighten fixing by described nut 107, it should be noted that, described nut needs the moment of torsion being tightened to requirement as requested.Such hobboing cutter body 101 just can press solidly on tool rest 102 by cutter shaft 103, voussoir 104, briquetting 106, bolt 105 and nut 107 tightly, and described tool rest 102 is welded on described cutterhead by special welding procedure simultaneously, Gu and hobboing cutter body 101 has just been fixed together with described cutterhead.

Concrete, the Hob fixing device of the development machine cutterhead using the present embodiment to provide, in tunneler construction process, if desired the parts of hobboing cutter body 101 are changed, staff does not need to enter face, point movable knife disc, the tool rest 102 that will change rotates to below, makes cutter shaft 103 in vertical position; Clean the hobboing cutter body 101 that worn and torn and periphery thereof and pull down the hobboing cutter body 101 worn and torn; After pulling down the hobboing cutter body 101 worn and torn, the fitting surface of tool rest is cleaned.

Then, staff loads onto voussoir 104, briquetting 106, high-strength bolt 105 and high strength nut 107, and tightens high strength nut 107 to the moment of torsion required after using special instrument that new hobboing cutter body 101 is pushed into tram.Because voussoir 104 has the enlarge-effect to power, by tightening high strength nut 107, the one side of high strength nut 107 is attached on briquetting 106, briquetting 106 is attached to again on tool rest 102, so high strength nut 107 is static relative to the position of tool rest 102, admittedly high-strength bolt 105 can only be driven to move, high-strength bolt 105 drives voussoir 104, more wedge is tighter by cutter shaft 103 for voussoir 104, and finally power is on request fastened on tool rest 102.

The technical scheme of the present embodiment, hobboing cutter body is arranged on tool rest, embed with the voussoir in fixation kit again in the gap of cutter shaft and tool rest rib, bolt is through voussoir and briquetting, with nut screwing clamping bolt to the moment of torsion required, cutter shaft, voussoir, bolt, briquetting and tool rest are tightly fixed together, and because voussoir has amplification to power, therefore cutter shaft can firmly be pressed on tool rest.And this fixed form does not need to enter face when making staff change hobboing cutter, it is fast that speed changed by hobboing cutter, and safety is higher.

Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
