Its main points are: the up end of installation base is equipped with the location cavity, is equipped with a setting spindle, the 2nd setting spindle on it in proper order to set up on the installation base with the screw, the part cover is on the 2nd setting spindle, and the part is pushed down to the clamp plate to compress tightly the part by the taut clamp plate of pull rod. The utility model discloses a jig, simple structure, adoption two -stage setting spindle proofread and correct the excircle after carrying out clearance centering again, and the regulation process is simple, directly uses the lathe oil hydraulic cylinder to compress tightly the part, does not need secondary calibration centering, the positioning accuracy height, the part uniformity of processing is good, the work -handling is convenient, and labour saving and time saving has improved the machining efficiency of part, not unidimensional part only needs to change the 2nd setting spindle who corresponds the size and can realize not unidimensional parts machining, has improved the utilization ratio of anchor clamps, has reduced frock clamp, has reduced the manufacturing expense of part.
Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of gear hobbing jig.
Background technology
Clamping workpiece on gear hobbing lathe, especially clamping planetary gear part, need to correct planetary gear cylindrical and beat, need after cylindrical has corrected to compress with pressing plate, because pressing plate part in compaction process has play, also will recheck cylindrical after compression and beat, leading time is long, complicated operation; Adopt the fixture of Internal hole positioning, need to carry out fine finishining to the size of planetary gear endoporus, processing request is high, causes larger processing cost.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of structure simple, regulates gear hobbing jig easy, easy to use.
Gear hobbing jig of the present utility model, comprises mounting seat, pressing plate and pull bar, it is characterized in that: the upper surface of described mounting seat is provided with located cavity, it is provided with successively the first apotting spindle, the second apotting spindle; The first described apotting spindle is provided with the first locating surface, locating flange and the second locating surface; The second described apotting spindle is provided with plane decided at the higher level but not officially announced; Described pull bar is connected and composed by one-level pull bar and secondary pull rod screw; The inner headed face of the located cavity in the first locating surface of the first apotting spindle and mounting seat touches, and by screws tighten in mounting seat; Second apotting spindle is enclosed within the first apotting spindle, and the plane decided at the higher level but not officially announced of the second apotting spindle and the second locating surface of the first apotting spindle touch, and by screws tighten on the first apotting spindle; Part is enclosed within the second apotting spindle, and pressing plate is pressed on part, pulls pressing plate compressing component by pull bar.
Jig of the present utility model, structure is simple, employing dual-positioning axle corrects cylindrical after carrying out gap centering again, regulates operation simple, direct use machine tool oil pressure cylinder carries out compressing component, do not need secondary calibration to feel relieved, positioning precision is high, and the part uniformity of processing is good; Work-handling is convenient, time saving and energy saving, improves part working (machining) efficiency; The part of different size, only need change the second apotting spindle of correspondingly-sized, can realize the part processing of different size, improve the utilization rate of fixture, decrease frock clamp, reduce the processing and manufacturing expense of part.
