The counter pulling long-hole boring cutter is characterized in that two ends of the cutter seat are respectively provided with a cutter blade, the horizontal distance between the two cutter blades is 0.5 to 1 millimeter, the cutter blades are tightly fixed on the cutter body through fastening screws, the cutter body is integrally connected with a connecting shaft through shaft connecting pins, the connecting shaft is provided with a guide sleeve, the guide sleeve is provided with at least four guide blocks, roller bearings are arranged between the connecting shaft and the guide sleeve, the cutter body and the guide sleeve are fastened into a whole through a fastening nut which is arranged on the connecting shaft, and the connecting shaft is further provided with a connecting body which is connected with a machine tool spindle. The counter pulling long-hole boring cutter is simple in structure, easy to manufacture, low in cost, strong in practical appliance, easy to operate, convenient and rapid to clamp a component and free from changing tools, is once centered, once accomplishes the processing of a long-step hole, improves machining precision, processing quality and production efficiency of the component and effectively reduces production expenses.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of reverse drawing hole boring cutter.
Background technology
Large and endoporus is the special pipe part of stepped hole for draw ratio, add man-hour at first behind deep hole boring machine processing through hole, adopt substep that through hole is expanded into stepped hole, adopt this method to add man-hour, need to repeatedly change cutter and centering, produce easily error at replacing cutter and centering process, cause low even overproof the scrapping of element precision of processing; Because this method need to repeatedly be changed cutter and centering, operation sequence is complicated, long processing time, and efficient is low.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provide a kind of simple in structure, cost is low, easy to operate, reverse drawing hole boring cutter that can processing step hole.
Reverse drawing of the present utility model hole boring cutter comprises cutter hub and tool rest, it is characterized in that: the two ends of described tool rest respectively are provided with a blade, are fixed tightly on the cutter hub by trip bolt; Described cutter hub is provided with connecting axle, is connected as a single entity by coupled axle-pin; Connecting axle is provided with fairlead, is provided with at least four guide pads on the fairlead; Described cutter hub and fairlead are tightened up by the locking nut on the connecting axle and are integrated.
In order better to realize above-mentioned purpose:
Also be provided with connector on the described connecting axle;
Also be provided with roller bearing between described connecting axle and the fairlead;
Level interval between described two blades is 0.5～1.0 millimeter.
Reverse drawing of the present utility model hole boring cutter, simple in structure, easy to manufacture, cost is low, practical, simple to operate; The parts fixation fast and easy does not need to change cutter, disposable centering, and the disposable processing of finishing profound stepped hole has improved machining accuracy and crudy and the production efficiency of part, effectively reduces producing cost.
Description of drawings
