Abstract
The utility model discloses a boring cutter bar processing a guiding tube bottom hole of an engine. A reversed V-shaped groove is formed in a guiding tube bottom hole cutter bar at the front end. A fine adjustment wedge block, a positioning steel ball and a regulating top screw are assembled in the groove. A radial fine adjustment structure is designed near each blade of a race bottom hole at the rear end. No matter how long service life of a tool is, and when the blades on the cutter bar at the front end (the guiding tube bottom hole blades) are abraded (or after cutter sharpening), and the processing size is not reached, the tool nose size can be added timely by adjusting the wedge block in the wedge block groove, and the radial size of the blades at the rear end can be added timely through fine adjustment at the rear end of the blades, so that the blades after the blades are abraded or after the cutter sharpening can be assembled to be used continuously, additional value of the tool is effectively improved, and using cost of the tool is saved.
Description
Technical field
The utility model relates to the cutter in the field of machining, is specifically related to a kind of boring cutter bar of processing the engine duct bottom outlet.
Background technology
The boring cutter bar insert design structure of existing processing engine duct bottom outlet is single, after (must in time changing blade) behind the blade abrasion or acquiring a certain degree the service life of cutter, the cutter groove of assembling is because blade mating surface frequent wear, might make point of a knife assembling back size can't reach the requirement of processing diameter dimension, scrap or repair, trouble and cycle are long during repairing.
The utility model content
The purpose of this utility model is the problem and shortage that exists at existing boring cutter bar, and a kind of boring cutter bar that structure is improved is provided.
Technical scheme: a kind of boring cutter bar of processing the engine duct bottom outlet, comprise cutter hub, knife bar and blade, knife bar is located at the cutter hub front end, the knife bar diameter is less than the cutter hub diameter, axial blade (conduit bottom outlet blade) is installed on the knife bar front end eccentric position, the uniform radially blade that is equipped with on the periphery of knife bar and cutter hub junction, axially blade and radially the rear end of blade be respectively arranged with micro-adjusting mechanism, wherein axially the upside of the knife bar of blade rear end is provided with the inverted V-shape groove, coupling is equipped with preceding wedge in it, should preceding wedge be semicircular structure, its center vertically is provided with screw and set screw is installed and positions and regulate, the front and back sides of wedge is up-small and down-big wedge structure before being somebody's turn to do, and cooperates with the inverted V-shape groove.Bottom at described semicircle wedge also is equipped with positioning ball.
Radially the inboard of blade be provided with the fine setting hole and the coupling be equipped with the back wedge, the center of this back wedge is provided with screwed hole and double-threaded screw is installed, back wedge and radially the blade contact position be set to the inclined-plane.Can regulate the length that blade radially stretches out the cutter notch by the rotation double-threaded screw.
The beneficial effects of the utility model: 1. no matter cutter life length, the blade on the front end knife bar (conduit bottom outlet blade) has wearing and tearing (or behind sharpening) slightly, when not reaching processing dimension, a voussoir that only needs to adjust in the wedge groove just can in time be augmented the point of a knife size.
2. the blade of rear end equally also can in time be augmented radial dimension with the fine setting of blade rear end, also can continue assembling behind the blade abrasion sharpening this moment and use, and effectively improves the added value of cutter, saves the cutter use cost.
