Description
Technical field
The utility model belongs to metal works thermal treatment auxiliary means technical field, relates to the supplementary unit that a kind of small crank carburizing and quenching multilayer is put.
Background technology
Bent axle is intermediate transmission part important in pump, is also the strength member realizing converting motion mode, by bent axle, the turning motion of bent axle input terminus is converted to the to-and-fro movement of plunger.Whether crankshaft designs is reasonable, and whether processing and manufacturing quality is qualified, directly affects reliability and the work-ing life of whole pump.
The bent axle that certain company designs manufactures, and produces sliding friction between plunger, in order to improve bent axle work-ing life, need carry out hard surfacing process, to improve the surface hardness of bent axle, make bent axle more wear-resisting with plunger phase-contact surface.
Bent axle 12 as shown in Figure 7.On the left of bent axle 12 as shown in Figure 8,8 M20 threaded holes 13 are bored., bore 1 M24 erection opening 14 on the right side of bent axle as shown in Figure 9, and Milling Process keyway 15.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of structure simple, easy to use, can ensure crankshaft quench effect, and the hard-faced supplementary unit of the bent axle that can increase work efficiency.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises top dish, positioning key and base, it is characterized in that: the erection opening corresponding to bent axle one end on described top dish is provided with the first through hole, keyway corresponding to bent axle is provided with square hole, and square hole side is provided with center hole; Described positioning key matches with the square hole on top dish; Described base comprises base plate, and the side of base plate is provided with second through hole corresponding with the threaded hole of the bent axle the other end, and the opposite side of base plate is provided with brace table, and the below of base plate is provided with the boss that is installed.
As a kind of preferred version of the present utility model, the brace table of described base is set to stepped.
As another kind of preferred version of the present utility model, one end of described positioning key is provided with hook.
The beneficial effects of the utility model: 1, the utility model is fixed by top dish one end by bent axle, fixed by the other end of base by bent axle, be then installed on intermediate frequency vertical quenching machine tool, can have quenched to bent axle, its structure is simple, easy handling and popularization.
2, after using supplementary unit, can ensure the quality that crankshaft journal surface quenches, axle journal hardness is even, reduces the labour intensity of operator, ensures the safety of operator, shortens the production cycle, enhances productivity, energy-saving and cost-reducing.
3, the utility model is stepped by being set to by brace table, can reduce the contact area of brace table and bent axle, improves positioning precision.
4, the utility model arranges hook by the end at positioning key, and positioning key can be avoided to come off from square hole, easy to use.
