Abstract

The utility model discloses a gap adjustable mechanism of screw rods and nuts, which comprises long ladder tooth nut and a short ladder tooth nut, wherein the sizes of inner bores of the long and the short ladder tooth nuts are identical, a ring-shaped groove is formed on the ring-shaped inner wall of one end of the long ladder tooth nut, and internal threads are formed on the ring wall of the ring-shaped groove; and external threads are formed on the ring-shaped outer wall of the short ladder tooth nut, the short ladder tooth nut is screwed in the ring-shaped groove of the long ladder tooth nut to form a combined nut, and a ladder tooth screw rod is screwed into the inner bores of the combined nut. The utility model is simple in structure and convenient to manufacture, enables the worktable of a machine tool to keep stable in operation, and improves the processing precision of the machine tool.

Description

The adjustable gaps mechanism of a kind of screw mandrel and nut
Technical field:
The utility model relates generally to a kind of mechanical structure, relates in particular to the adjustable gaps mechanism of a kind of screw mandrel and nut.
Background technique:
Composite structure for common screw mandrel and nut, when a masterpiece is used on the nut, on the screw mandrel between corresponding terraced tooth certain axial clearance can appear on the terraced tooth of a side and the nut, because the existence of this axial clearance, to be difficult to guarantee that machine table has a position accurately when work, have influence on the machining accuracy of lathe.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of simple in structure, the adjustable gaps mechanism of screw mandrel and nut.
The utility model is achieved through the following technical solutions:
The adjustable gaps mechanism of a kind of screw mandrel and nut is characterized in that: terraced tooth nut of length that hole size is identical in including and short terraced tooth nut, have annular groove on the annular inner wall of terraced tooth nut one end of described length, and the ring wall of described annular groove is provided with internal thread; The annular outer wall of the terraced tooth nut of described weak point is provided with outside thread, and the terraced tooth nut of described weak point screws in the interior assembled nut of forming of annular groove of long terraced tooth nut, has terraced tooth screw rod to screw in the endoporus of assembled nut.
Can relatively rotate a phase angle between terraced tooth nut of length in the utility model and the short terraced tooth nut, so, the gap of terraced tooth screw mandrel and assembled nut can be placed the both sides of two nuts respectively, that is, the gap of long terraced tooth nut and terraced tooth screw mandrel is present in the left side of terraced tooth on the terraced tooth screw mandrel; Gap between short terraced tooth nut and terraced tooth screw mandrel is present in the right side of terraced tooth on the terraced tooth screw mandrel.So, just formed no gap in the axial direction between assembled nut and the terraced tooth screw mandrel.
The utility model has the advantages that:
The utility model is simple in structure, and is easy to prepare, makes machine table can keep stable at work, improved the machining accuracy of lathe.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged view of A portion.
Embodiment:
The adjustable gaps mechanism of a kind of screw mandrel and nut, terraced tooth nut 1 of the length that hole size is identical in including and short terraced tooth nut 2 have annular groove on the annular inner wall of terraced tooth nut 1 one ends of described length, and the ring wall of described annular groove is provided with internal thread; The annular outer wall of the terraced tooth nut 2 of described weak point is provided with outside thread, and the interior assembled nut of forming of annular groove that the terraced tooth nut 2 of described weak point screws in long terraced tooth nut 1 has terraced tooth screw rod 3 to screw in the endoporus of assembled nuts.
Fig. 2 as seen, long terraced tooth nut 1 and the gap 4 of terraced tooth screw mandrel 3 are present in the left side of terraced tooth on the terraced tooth screw mandrel 3; The gap 5 that short terraced tooth nut 2 and terraced tooth screw mandrel are 3 is present in the right side of terraced tooth on the terraced tooth screw mandrel 3.So, just formed no gap in the axial direction between assembled nut and the terraced tooth screw mandrel 3.
