Description
The utility model belongs to a kind of bent axle and adds the instrument that uses man-hour, is meant a kind of crankshaft journal polisher especially.
At present, in bent axle processing and maintenance, when crankshaft journal is polished, the normal method of using has two kinds, a kind of is the length of polishing axle journal as required, with two width battens with matching, its end is connected with hinge, according to the size of crankshaft journal, dig out two semi-circular groove then at the batten middle part, in groove, load onto the felt bar, then it is enclosed within on the crankshaft journal that needs polishing, exerts pressure, clamp the axle journal of bent axle at the free end of two battens, rotary crankshaft polishes axle journal then; Another kind method is directly to be enclosed within on the axle journal that bent axle need polish with the felt bar, and applies certain tensile force at the two ends of felt bar, and rotary crankshaft polishes then.The former wastes timber, and will do different clamping plate, bad adaptability for different bent axles; The latter uses inconvenience, and polishing effect is undesirable, promptly polishes inhomogeneous.
The purpose of this utility model provides a kind of different thicknesses, length crankshaft journal of being adapted within the specific limits, and polishing effect uniform crankshaft journal polisher.
The purpose of this utility model is achieved in that a kind of crankshaft journal polisher, comprises the felt bar, and it also includes support, tightening belt, felt bar device for spreading, U-shaped belt positioning hanger, belt tension positioner and support frame positioning device; Its medium-height trestle is a strip support, and symmetry is installed with pin respectively in its front center both sides, is connecting support frame positioning device at the end of support; The front end of felt bar and the front end of tightening belt are fixed together, and are also connecting U-shaped belt positioning hanger at the front end of tightening belt, and its pin by the support front end is articulated in the front end of tightening belt and its inboard felt bar on the support; Middle front part at the felt bar leans on a side of tightening belt fixedly mounting felt bar device for spreading, the felt bar is having a kerf with felt bar device for spreading connection along the longitudinal axis center line of felt bar, the top of felt bar device for spreading is provided with the location ring set, and tightening belt passes the end of this location ring set and felt bar and joins; End at tightening belt is installed with a link; The belt tension positioner is movably arranged on the rear portion of support, and is connected with the link of tightening belt end by the belt tension spring on it.
When using the utility model,, the work girth and the tensile force of felt bar can be adjusted, its bent axle that adapts to different thicknesses polishing needs can be made by the belt tension positioner on the utility model; In addition because the utility model is provided with felt bar device for spreading, it is under the tensile force of tightening belt, by supporting leg and the presser feet in the felt bar device for spreading, the felt bar is outwards opened on the direction perpendicular to the felt bar longitudinal axis, its open width depends on the length of crankshaft journal; Its purpose has three, and the one, enlarge the utility model and adapted to the different polishing needs of small crankshafts greatly; The 2nd, strengthen polishing action, so that crankshaft journal uniform polish on its length direction to the crankshaft journal two ends; The 3rd, can prevent the utility model sideslip.
