Abstract
The utility model relates to a regulating positioning machine of a rotary shaft of a workpiece box of a processing machine tool of a spiral bevel gear, which is composed of an eccentric sleeve, fixing screws and a positioning pin. The utility model is characterized in that the eccentric sleeve is a sleeve of which the middle part is provided with an eccentric hole and the outer side of the upper end is provided with a flange, the eccentric sleeve is arranged in a shaft hole of the rotary shaft of the workpiece box, and the rotary shaft of the workpiece box is inserted in the eccentric hole of the eccentric sleeve; a plurality of screw holes are evenly distributed on the flange of the eccentric sleeve, the fixing screws are penetrated through the screw holes to cause the adjusted eccentric sleeve to be fixed in the rotary shaft hole, a positioning pin hole is arranged in the proper position of the flange of the eccentric sleeve after adjustment and positioning, and the positioning pin is inserted in the positioning pin hole. The utility model has the advantages that the rotary shaft can use the rotation of the eccentric sleeve to be precisely adjusted and positioned when assembled, regulation is simple, and precision of vertical cross of the shaft line of the workpiece main shaft and the shaft line of the rotary shaft of the workpiece box is ensured; in addition, because the assembling position of the rotary shaft can be adjusted and corrected, processing difficulty of the two shaft holes is reduced so as to reduce the processing expenses.
Description
Technical field
The utility model belongs to the parts of lathe, particularly relates to the intersect vertically adjustment positioner of spiral bevel gear machining tool workpiece box gyroaxis of accuracy of a kind of work spindle axis that guarantees workpiece box and axis of rotation.
Background technology
The spiral bevel gear machining tool is the gear machining apparatus that a kind of multi-coordinate axle is, the positioning accuracy of its each reference axis plays crucial effects to the machining accuracy of finished product, for example the work spindle axis of the workpiece box on the coordinate shaft type spiral bevel gear milling machine and workpiece box axis of rotation intersect vertically and the machining accuracy that deviation will have a strong impact on gear occurs, thereby its specification requirement is strict, promptly its error must not be greater than 0.005mm.In present known technology, above-mentioned two axes intersect accuracy are to rely on the assembly precision of workpiece box gyroaxis to guarantee, the accuracy that is to say two axes intersect depends on the machining accuracy of the work spindle axis hole and the gyroaxis axis hole relative position of workpiece box, but reach specification requirement, difficulty of processing is very large, and not only accuracy is not easy to guarantee, and because difficulty of processing is big, to the requirement on machining accuracy height of process equipment, thereby processing charges is also very high.
Summary of the invention
The utility model provides the adjustment positioner of the spiral bevel gear machining tool workpiece box gyroaxis that a kind of work spindle axis that guarantees workpiece box and axis of rotation intersect vertically accuracy for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of adjustment positioner of spiral bevel gear machining tool workpiece box gyroaxis, by eccentric bushing, hold-down screw and shop bolt are formed, eccentric bushing is that the centre has eccentric orfice, the outside, upper end has the sleeve of flange, it is installed in the gyroaxis axis hole of workpiece box, the gyroaxis of workpiece box is inserted in the eccentric orfice of eccentric bushing, be evenly equipped with several screws on the flange of eccentric bushing, hold-down screw passes screw and adjusted eccentric bushing is fixed in the revolution axis hole of workpiece box, also have dowel hole on the appropriate location of the eccentric bushing flange after adjusting the location, shop bolt inserts in dowel hole.
Advantage and the good effect that the utlity model has are: owing to installed the adjustment positioner of being made up of eccentric bushing etc. additional between the gyroaxis axis hole of workpiece box and gyroaxis, make gyroaxis when assembling, can proofread and correct the location accurately by the rotation of eccentric bushing, thereby adjust easy, and available screw is fixed on eccentric bushing in the revolution axis hole, make the gyroaxis holding position behind the location constant, eliminated because the gyroaxis location that the machining deviation of main shaft axis hole and gyroaxis axis hole relative position causes is inaccurate, thereby the work spindle axis of workpiece box and the accuracy that axis of rotation intersects vertically have been guaranteed, in addition because the rigging position of gyroaxis can be adjusted correction, reduce the difficulty of processing of two axis holes, and then reduced processing charges.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of A among Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Label among the figure is respectively: the 1-workpiece box; 2-circular cover hold-down screw; The 3-circular cover; 4-eccentric bushing hold-down screw; The 5-eccentric bushing; The 6-gyroaxis; The 7-shop bolt.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the adjustment positioner of spiral bevel gear machining tool workpiece box gyroaxis, have eccentric orfice (its diameter is pressed the processing of gyroaxis diameter) by the centre, the outside, upper end has the eccentric bushing 5 of flange, fixedly the screw 4 of eccentric adjusting sleeve and shop bolt 7 are formed, for packing eccentric bushing in the gyroaxis axis hole of workpiece box 1 into, the diameter of revolution axis hole is pressed the diameter processing of eccentric bushing, and process the concave station that the flange of eccentric bushing can be embedded on the top of axis hole, uniform several screws that has on the flange of eccentric bushing, its quantity can be determined by the requirement that reality is adjusted, present embodiment has 6 screws, and the revolution axis hole concave station on the also uniform screw of opening same quantity, during installation eccentric bushing pack into the revolution axis hole in, utilize the eccentric orfice of eccentric bushing that the workpiece box that eccentric bushing is housed is inserted on the gyroaxis of installing on the workpiece box slide rail 6 then, then rotate and adjust eccentric bushing, make gyroaxis axis and work spindle intersect vertical axis, and determine that its worst error is no more than 0.005mm, at this moment hold-down screw is screwed in the screw, eccentric bushing is fixed, in addition, one or two dowel hole is bored in appropriate position on the eccentric bushing flange, boring will be bored in the boss of revolution axis hole, at last shop bolt is placed in the pin-and-hole, so that when afterwards lathe being keeped in repair as telltale mark, present embodiment has also been installed a circular cover 3 eccentric bushing suitable for reading, it is fixed on the eccentric shaft with screw 2, to play dustproof and effect attractive in appearance.
The utility model is particularly useful for super large-scale spiral bevel gear machining tool.
