Description
Technical field
The utility model relates to a kind of hand-held surface of the work milling tools, specifically, relates to a kind of instrument that is used for repair welding place of the plane of workpiece, interior concaved circular cambered surface and outer convex arc surface is implemented polishing, belongs to the metal working process equipment technology.
Background technology
Polishing after the repair welding of the backing roll of the plane of prior art workpiece, interior concaved circular cambered surface such as heavy (merchant) mill, jackshaft and working roll bearing block inner arc surface and outer convex arc surface such as big-and-middle-sized working roll and cylindrical shell exterior arc surface, all is the manual grindings that adopt emery wheel and polished silicon wafer.The polishing of this method not only work efficiency is low, and very difficult its polishing amount of control, very easily cause repair welding burnishing part plane whole or interior circle or cylindrical injustice (protrusion or recessed) with it, and tangible polishing vestige is arranged around the burnishing part, this not only influences the roughness of described surface of the work, and very not attractive in appearance, serious also can cause quality accident.
Summary of the invention
The utility model aims to provide a kind of rational in infrastructure, easy to operate, and the polishing quality is good, the hand-held surface of the work milling tools of high efficiency, to overcome the deficiency of prior art.
The utility model realizes that the technical scheme of its purpose is:
A kind of hand-held surface of the work milling tools comprises the electric grinder that emery wheel is housed, and its creativeness is, also comprises left backing roll, right backing roll, crossbeam, column, first adjusting nut and second adjusting nut; The equal diameters of described left backing roll and right backing roll; The two ends of crossbeam are tangent with the cylindrical of left backing roll and right backing roll respectively and fixedly connected; One end of column is connected with electric grinder, and the other end of column is provided with external thread section, and the external thread section of described column is located in the through hole in crossbeam centre and is the axis hole sliding fit; First adjusting nut and second adjusting nut are located at the both sides of crossbeam respectively and twist mutually with the set external thread section of column and close, thereby make crossbeam be connected with column; Can adjust vertical range between emery wheel and the crossbeam by regulating first adjusting nut and second adjusting nut.
Can understand by above given technical scheme, the utility model by left and right backing roll (also can be referred to as the pattern roller) for the mould that is abutted against of normal surface of the work, column is by the adjusting of adjusting nut, make emery wheel be in same horizontal plane respectively with the cylindrical point of contact of left and right backing roll or make emery wheel and left and right backing roll three's cylindrical point of contact line constitute with workpiece in concaved circular cambered surface (interior circle) or the identical radius of curvature of outer convex arc surface (cylindrical), respectively implemented to polish in the plane of workpiece or repair welding place of interior circle or cylindrical then.When left and right backing roll normally was abutted against the plane of workpiece or inner arc surface or exterior arc surface, polishing promptly came to an end and ends.So just can not cause the problem of repair welding burnishing part female or male surface of the work, also can around burnishing part, not produce the obviously phenomenon of polishing vestige, and easy to operate, high efficiency, thus realized the purpose of this utility model.
The utility model advocates that also described left backing roll and right backing roll are respectively equipped with cylindrical side cut plane (being commonly called as " flat department "), and perpendicular with the center line of left backing roll and right backing roll respectively and both length of side (chord length) in described side cut plane equates; Fixedly connected with the set cylindrical side cut plane of left backing roll and right backing roll respectively in the two ends of described crossbeam.This technical scheme is because the set cylindrical side cut plane of its left and right backing roll, can make things convenient for itself and being connected of crossbeam, and not only can weld but also can connect with screw.And do not establish the left and right backing roll on cylindrical side cut plane and being connected of crossbeam, the general employing welded (built-up welding) connection.
For making and consideration easy to use, the utility model also advocates, the two ends of described crossbeam respectively with the fixedlying connected of left backing roll and right backing roll, be welded to connect or removable screw fixedly connected.Can make things convenient for described backing roll to keep in repair because of service wear because screw connects, the utility model is actively recommended.
The utility model advocates that also described crossbeam has 2, and 2 crossbeams are parallel arranged apart; Described column has 2, and the two ends of 2 root posts are connected with crossbeam with electric grinder respectively.The reliability that this technical scheme is connected with cross rail for electric grinder will produce positive effect, and to the normal stability under the emery wheel operating mode, tangible positive effect is arranged also.If adopt the structure of a crossbeam and a column, as long as strengthen the diameter of column, and add and the crosspiece of column welding at an end of column, be connected with electric grinder by at least 2 screws by crosspiece then, then can guarantee the operate as normal of electric grinder equally.But, under the less lighter condition of electric grinder, directly be connected with electric grinder with 1 column, be can not produce dysgenic.
After technique scheme was implemented, what the utility model had was rational in infrastructure, easy to operate, and surface of the work polishing quality is good, and high efficiency gets characteristics, is conspicuous.
