Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-3, a kind of Machining Spiral Bevel Gear fixture, including upper chuck 1 and lower chuck 2, described upper chuck 1 is hollow cylindrical structure, and upper chuck 1 upper end has circular peace race 3, and gear is put into by pacifying race 3, and upper chuck 1 lower end has rounded transitional groove 4；Being uniformly provided with four beam callipers 5 in described upper chuck 1 cavity, described beam calliper 5 is arc block structure, and beam calliper 5 intrados has the sawtooth 6 of some continuous layouts, promotes grip, and beam calliper 5 is symmetrical arranged two-by-two；Described beam calliper 5 extrados center is all fixing with the first push rod 8 of the first hydraulic jacking cylinder 7 to be connected, described first hydraulic jacking cylinder 7 is all fixing with upper chuck 1 to be connected, it is respectively connected with hydraulic tube 9 between adjacent two the first hydraulic jacking cylinders 7, wherein a road hydraulic tube 9 is drawn upper chuck 1 and is connected with the first hydraulic joint 10, described first hydraulic joint 10 is fixedly connected on upper chuck 1 outer wall, four the first hydraulic jacking cylinder 7 degrees of tightness are controlled by hydraulic synchronization, easy to operate, time saving and energy saving；Described lower chuck 2 is fixedly connected on upper chuck 1 lower end, lower chuck 2 centrage aligns with upper chuck 1 centrage, lower chuck 2 is hollow cylindrical structure, lower chuck 2 upper end no-top plate, lower chuck 2 lower end has circle and goes out race 11, is uniformly provided with four little slide calliper rule 12 in described lower chuck 2 cavity, and described little slide calliper rule 12 are arc block structure, little slide calliper rule 12 intrados has the sawtooth 6 of some continuous layouts, and little slide calliper rule 12 are symmetrical arranged two-by-two；Described little slide calliper rule 12 extrados center is all fixing with the second push rod 14 of the second hydraulic jacking cylinder 13 to be connected, described second hydraulic jacking cylinder 13 is all fixing with lower chuck 2 to be connected, it is respectively connected with hydraulic tube 9 between adjacent two the second hydraulic jacking cylinders 13, wherein a road hydraulic tube 9 is drawn lower chuck 2 and is connected with the second hydraulic joint 15, and described second hydraulic joint 15 is fixedly connected on lower chuck 2 outer wall.
Operation principle of the present utility model is: be first connected with the first hydraulic joint 10 and the second hydraulic joint 15 respectively by two-way conduit under fluid pressure, spiral bevel gear is put into by pacifying race 3, spiral bevel gear is placed in little slide calliper rule 12 upper end of lower chuck 2 through lead-over groove 4, the first hydraulic jacking cylinder of hydraulic control subsequently 7 clamps, to Machining Spiral Bevel Gear；It may be noted that when spiral bevel gear Type Diameter is less, need first hydraulic control the second hydraulic jacking cylinder 13 elongation to make little slide calliper rule 12 close tightly, it is to avoid spiral bevel gear spills from the race 11 that goes out of lower end；Adding man-hour when spiral bevel gear being applied big torsion, can be unclamped by little slide calliper rule 12, be positioned over by spiral bevel gear in the middle of little slide calliper rule 12 and beam calliper 5, tighten up beam calliper 5 and little slide calliper rule 12 simultaneously, double caliper compresses and improves fastening effect, it is ensured that gear does not slides；When needing it is processed after the connecting assemblies such as spiral bevel gear and spline, the opening that this utility model is positioned on lathe, spline inserts the little interior race 11 that goes out through lower end of slide calliper rule 12 and stretches out, regulate to suitable working height, tighten up little slide calliper rule 12 or tighten up beam calliper 5 and little slide calliper rule 12 simultaneously, directly spiral bevel gear can be processed, it is not necessary to it is split with spline, save man-hour and labour force.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
