Description

A kind of bridge-type reverse boring cutter
Technical field
The utility model relates to a kind of boring cutter, specifically, relates to a kind of bridge-type reverse boring cutter.
Background technology
Common boring cutter main shaft when boring extends (or workpiece is gradually near main shaft) gradually, promptly positive boring, on the contrary boring cutter main shaft when boring shortens (or workpiece is gradually away from main shaft) gradually, then is anti-boring.Anti-boring normally is used in a less hole between boring position and main shaft when going to process a bigger hole (being stepped hole).
At present, common bridge-type boring cutter is mainly by handle of a knife 1, flange 2, cutter bridge 4, slide block 5, cutter holder 6 and blade 7 are formed, as shown in Figure 7, the front end sleeve of handle of a knife 1 is equipped with flange 2, the front end of this flange 2 has groove, cutter bridge 4 is housed in the groove, the front end of cutter bridge 4 is provided with V-type slide rail 11, and slide block 5 is installed on the two ends of V-type slide rail 11, and this slide block 5 is provided with the V-type groove with the V-type slide rail with matching, slide block 5 can slide at V-type slide rail 11, through screw cutter holder 6 is installed on the slide block 5, blade 7 is installed on the cutter holder 6, cutter bridge 4 is fixed on the flange 2 through screw 8, realize the diametric(al) fine adjustments by slide block 5, by more tool changing bridge 4 realization diametric(al) adjustings in a big way.But common bridge-type boring cutter can't anti-boring, and anti-if desired boring processing in the job shop is ownly usually processed a handle of a knife, the length of manual adjustment blade then, and this mode not only efficient is low, but also the problem of low precision.BIG company has produced a kind of fine boring cutter, both just boring also can anti-boring for this boring cutter, and during positive boring, cutter holder is installed in the front end of cutter bridge, during anti-boring, cutter holder then is installed in the rear end of cutter bridge, realizes positive boring and anti-boring by the position of adjusting cutter holder, still, because the length of cutter holder is fixed, the flexible distance of blade is limited, and therefore this boring cutter can only all can not be realized anti-boring function for other hole to the stepped hole boring of shoulder height less than 25mm; And the heavy boring boring cutter does not all have anti-boring function, and therefore, these cutters all can't be processed the hole of endoporus step greater than 25mm at present.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of bridge-type reverse boring cutter, and this bridge-type reverse boring cutter can carry out anti-boring processing to the hole of various endoporus shoulder heights.
For achieving the above object, thereby the utility model, with the commutation of boring cutter fore-end is realized the purpose that anti-boring is processed is carried out in the hole of various endoporus shoulder heights by anti-boring flange.Concrete technical scheme is: a kind of bridge-type reverse boring cutter, comprise flange and cutter bridge, wherein, the cutter bridge location is in the place ahead of flange, and an end of this cutter bridge is provided with the V-type slide rail, the two ends of V-type slide rail are provided with slide block, blade is installed on the slide block, is provided with anti-boring flange between described flange and the cutter bridge, this anti-boring flange is positioned at the middle part of described cutter bridge, and anti-boring flange and described slide block are positioned at the same side of cutter bridge, and described cutter bridge and anti-boring flange are fastened on the described flange through screw in the lump.
Because the blade of positive boring cutter is at front end, the utility model, is shifted one's position thereby blade is also corresponding positive boring cutter fore-end commutation by anti-boring flange, has realized the function of reverse boring, satisfies the processing of some special constructions.The utility model is realized diametric fine adjustments by moving slider, regulates in a big way by more the realization of tool changing bridge is diametric, thereby has satisfied the requirement of the hole of various endoporus shoulder heights being carried out anti-boring processing.
As preference, above-mentioned anti-boring flange front end is provided with the notch cuttype groove, and described V-type slide rail is housed in this notch cuttype groove; The rear end of described anti-boring flange is provided with boss, and this boss is packed in the groove of described flange front end.
Have measured hole vertically on above-mentioned anti-boring flange, the axial line of this measured hole is vertical with the axial line of described anti-boring flange.By this measured hole, do not need withdrawing just can use inside micrometer, pass this measured hole and treat the aperture of machining hole and measure, if the aperture does not reach requirement, then withdrawing is regulated the position of blade, processes if reach requirement then continue, save the step of withdrawing, improved operating efficiency.
In order to alleviate the weight of whole anti-boring flange, alleviating the pressure that boring cutter causes main shaft, on the above-mentioned anti-boring flange with described measured hole perpendicular have a hole.
Beneficial effect: the utility model is not only realized anti-boring processing is carried out in the hole of various endoporus shoulder heights compared with before-improvement, and the utility model has been expanded the function of boring cutter by anti-boring flange, make the utility model keep the high characteristic of boring cutter precision, the precision that makes anti-boring add man-hour is guaranteed, and efficient is improved; And anti-boring flange arrangement is simple, and shape is regular, and is easy to process, and manufacturing expense is cheap.
