Abstract
The utility model relates to a threaded connection mechanism which can be used for accuracy regulation and fixed connection between large-scale basic parts of a machine tool. The threaded connection mechanism is particularly suitable for regulating and fixing a gantry framework of a gantry type boring-milling machine. The threaded connection mechanism is characterized in that a steel sleeve is inlaid in a lower end face body of a vertical column and is fixed through a cone-end stopper screw. A lower portion spherical surface cushion and a spherical surface screw are arranged in the steel sleeve, wherein the spherical surface screw is in screw thread fit with the steel sleeve. A hexagonal nut is matched with the spherical surface screw. One end of a double-head bolt is arranged in a sliding base body in a screwed mode. The other end of the double-head bolt is sequentially provided with a conical surface cushion, an upper portion spherical surface cushion, a spring shim and a hexagon nut, wherein the conical surface cushion, the upper portion spherical surface cushion, the spring shim and the hexagon nut are locked tightly through the hexagon nut at the other end of the double-head bolt. By using the threaded connection mechanism, the amount of holes in the lower end face of the vertical column can be reduced effectively and the risk that the large-scale basic parts are discarded as useless can be avoided. Moreover, a contact area between the vertical column and a sliding base can be ensured so that contact rigidity can be improved.
Description
Technical field
The utility model relates to a kind of threaded connection, for can be used for adjusting precision and the threaded connection that is fixedly connected with between lathe large foundation spare.Be particularly useful for adjusting and fixing planer type boring milling bed gantry frame.
Background technology
Usually need in practice the gantry frame lower surface is fixed on the slide upper surface, and adjust the precision of two basic parts.Traditional design organization is two screwed holes on two screw thread members and basic part, and a screw thread member is realized the function on top (adjustment precision), and a screw thread member realizes pressing the function of (being fixedly connected with).There are two problems in this traditional project organization in adjusting the lathe gantry frame: one, the material of the basic part of lathe is usually foundry goods, the castings material characteristic is to bear the compression the same with steel part, and is easy to reach the yield limit of material and damages during tension.It two, one draws the two external threading bindiny mechanisms on a top to open a clear opening and a screwed hole on column body lower surface, and whole gantry frame has very large weight, and realize adjusting precision and fixed function will have this threaded connection of some to realize.But it is limited that the column end face allows the zone of punching.
Summary of the invention
The purpose of this utility model is to connect the deficiency of project organization for conventional threads, and designs a kind of thread mechanism that also can press that both can push up, and is used for threaded connection fixing between the heavy machine tool basic part and the adjustment precision.Take the quantity in the hole of reducing the column lower end face as purpose, the risk of avoiding large foundation spare to scrap improves the fixing reliability of basic part.
The threaded connection of the said adjustable connecting components spacing of the utility model is to can be applicable in the moving beam boring and milling machine of large-sized numerical control gantry-travelling, is fixedly connected with mechanism between column and slide.The constituted mode of said threaded connection is, steel bushing is embedded in column lower end face body, and fix with cone end holding screw, bottom ball ring and sphere screw are arranged in steel bushing, threaded engagement between sphere screw and steel bushing, hexagonal (hexagon)nut has the structure that matches with sphere screw, to realize adjusting the position of sphere screw in steel bushing by the rotation hexagonal (hexagon)nut, reaches the distance of adjusting between column and slide seat body.Stud one end screws in by hexagonal (hexagon)nut and sphere screw center and is arranged in slide seat body, the stud other end on hexagonal (hexagon)nut, be disposed with conical surface pad, top ball ring, spring shim and hex nut, rely on the hex nut locking that is arranged on the stud other end.
By this threaded connection adjust between column lower end face and slide upper surface distance and fixing after, guarantee the contact area of column and slide by the process of encapsulating, thus the raising contact stiffness.On the said thread mechanism of the utility model, part and lower part respectively have a pair of sphere parallels, lower spherical calotte parallels design is in order to guarantee the contact area between part, the contact of assurance rigidity, upper spherical calotte parallels design are the reliabilities in order to guarantee that the said threaded connection of the utility model is fixing.Utilize the said thread mechanism of the utility model, can effectively reduce the quantity of column lower end face, the risk of avoiding large foundation spare to scrap.
Description of drawings
Fig. 1 is the threaded connection structure diagram.
The specific embodiment
Constituting of the said threaded connection of the utility model, steel bushing 1 is embedded in column 2 lower surface bodies, and fixing with cone end holding screw 3, bottom ball ring 4 and sphere screw 5 are arranged in steel bushing 1, bottom ball ring 4 contacts with slide seat body 8, threaded engagement between sphere screw 5 and steel bushing 1 has on hexagonal (hexagon)nut 6 and can stir or rotate the structure that sphere screw 5 matches; One end of stud 7 screws in slide seat body 8 by hexagonal (hexagon)nut 6 and sphere screw 5 centers, on the stud 7 outside hexagonal (hexagon)nut 6, sets gradually conical surface pad 9, top ball ring 10, spring shim 11 and hex nut 12.
The mounting means of the said threaded connection of the utility model and step are, at first with cone end holding screw 3, steel bushing 1 is mounted in column 2 lower surface bodies, then load section's ball ring 4 and sphere screw 5, utilize spanner rotation hexagonal (hexagon)nut 6 to adjust sphere screw 5 in the position of steel bushing 2, reach the distance of adjusting between column 3 and slide seat body 8.Again stud 7 one ends are screwed in slide seat body 8, then be inserted in successively conical surface pad 9, top ball ring 10, spring shim 11, at last hex nut 12 is screwed in the other end and the locking of stud 7.
Claims (3)
1. the threaded connection of an adjustable connecting components spacing, it is characterized in that, steel bushing is embedded in column lower end face body, and fix with cone end holding screw, bottom ball ring and sphere screw are arranged in steel bushing, threaded engagement between sphere screw and steel bushing, hexagonal (hexagon)nut matches with sphere screw, stud one end screws in and is arranged in slide seat body, and the stud other end on hexagonal (hexagon)nut is disposed with conical surface pad, top ball ring, spring shim and hex nut.
2. according to the said threaded connection of claim 1, it is characterized in that, said stud one end screws in to be arranged in slide seat body and is, an end of stud screws in slide seat body by hexagonal (hexagon)nut and sphere screw center.
