Abstract
The utility model relates to a flexible link case, that the ball stud nut seat in the numerical controlled machine tool is jointed with the moving parts. The link case includes a ball stud nut seat, a moving part, a connecting plate and a tightening screw. The link case is characterized in that a through hole is set at the center of the connecting plate, and the sleeve is fixed in the column hole at the upper center of the ball stud nut and a T-shape positioning pin set in the sleeve through the hole of the connecting plate. The upper top of the locating column is connected with the connecting plate by the bolt. The upper end surface of the ball stud nut seat is also fitted with a spring hole in which the spring is fitted to connect the connecting plate with the ball stud nut seat linked with the moving parts by the tightening stud and the connecting screw. A through hole is located at one side of the lower end of the center sleeve on the upper of the ball stud nut seat; a column-type pressing block, a spring and an adjusting screw are placed in this hole from the inner to the outer. The pressing block is pressed to the locating column in the sleeve.
Description
One, technical field
The utility model relates to connecting of numerical control machine tool ball screw nut seat and moving element, especially for the numerical control machine tool ball screw nut seat of numerical control high-precision cylindrical grinder and the flexible coupling mechanism of moving element.
Two, background technique
The motion of numerically controlled machine all is to utilize alternating current servomotor to drive the ball screw rotation, and through nut seat and stationary table, the mutarotation transhipment is moving to be straight line motion.For improving the movement velocity and the Location accuracy of lathe, all adopt and be rigidly connected, the general match grinding that adopts between the upper end of ball screw nut seat and connecting plate is adjusted pad, and then connecting plate is fastenedly connected on ball screw nut seat and moving element with fastening screw, under the effect of ball screw and nut seat, worktable moving linearly on machine tool guideway that moving element and connecting plate are constituted, so only solved the motion stiff problem of moving element, but the error that the parts that can't eliminate its associated couplings bring in processing and assembling, cause the numerical control external cylindrical grinding machine when the working shaft-like part, the finished surface of part produces extremely unconspicuous spiral lamination (its pitch is consistent with ball screw) and can't eliminate at all, and lathe can't regulate when having used a period of time wearing and tearing to occur with rear rail automatically, causes the geometric accuracy of lathe to reduce.
Three, summary of the invention
The purpose of this utility model is to provide a kind of simple in structure can eliminate the part error that the associated couplings part produces in the manufacturing process, improve the part to be processed precision, and regulate automatically can wearing and tearing occur because of guide rail the time, guarantee that the geometric accuracy of lathe is unlikely the numerical control machine tool ball screw nut seat of reduction and the flexible coupling mechanism of moving element.
The utility model has adopted such technological scheme: the flexible coupling mechanism of a kind of numerical control machine tool ball screw nut seat and moving element, include the ball screw nut seat, moving element, connecting plate and fastening screw, it is characterized in that aforesaid connecting plate center is provided with through hole, the central upper portion of ball screw nut seat is provided with cylindrical hole, be installed with lining in this cylindrical hole, one T shape locating column passes the through hole of connecting plate and is located in the lining, the upper end of locating column is connected through bolt with connecting plate, the upper-end surface of ball screw nut seat also is provided with spring eye, be provided with spring in the spring eye, connecting plate connects with moving element and ball screw nut seat through fastening screw and attachment screw, lining lower end one side of aforesaid ball screw nut seat central upper portion is provided with a through hole, in this through hole, be provided with the cylindricality compact heap from inside to outside, spring and adjustment screw, the locating column crimping in compact heap and the lining.
The numerical control machine tool ball screw nut seat that the utility model provides and the flexible coupling mechanism of moving element, owing in connecting plate and ball screw nut seat, be provided with locating column, the upper end of ball screw nut seat also is provided with spring, lining lower end at the ball screw nut seat is provided with compact heap, spring and adjustment screw, connecting for flexible between ball screw nut seat and the moving element connected, therefore the error of bringing in the time of can adjusting and eliminate the associated couplings parts because of processing or assembling preferably, thereby improve the precision of processing accessories, not only eliminated the extremely unconspicuous screw thread vestige that workpiece surface occurs, but also the upgrading that has improved surface roughness, the assembling difficulty that has solved the existence of high precision numerical control grinding machine is big, debug very difficult, the difficult problem of grinding accuracy poor stability, the surface finishment of grinding work piece can be stablized and reach 9 grades; Even machine tool guideway also can automatically adjust by locating column and spring because of wearing and tearing, guaranteed the geometric accuracy of lathe, it is simple in structure, has improved the working life of screw mandrel and guide rail, reduce the processing cost and the installation time of associated couplings part, improved productivity effect greatly.
