Abstract
The utility model discloses a hanging device for carburizing and quenching a gear shaft, which comprises a hanging column, an upper support plate, a lower support plate, a bottom plate and five same upright columns. The hanging column penetrates through the central holes of the upper support plate and the lower support plate and is fixed with the upper support plate, the lower support plate and the bottom plate in a welding manner; the top of the hanging column is provided with a hanging hole; the five upright columns penetrate through holes circumferentially and evenly distributed on the upper support plate and the lower support plate respectively and are then fixed with the upper support plate, the lower support plate and the bottom plate in a welding manner; the top ends of the five upright columns are leveled with the upper support plate; and the diameters of the five upright columns are the same as that of the hanging column; the upper support plate is provided with five through holes which are circumferentially and evenly distributed for placing the gear shaft and is evenly distributed with five oil holes on two circles of different diameters; the lower support plate has the same structure as the upper support plate; and the bottom plate is provided with four oil holes which are circumferentially and evenly distributed. By carburizing and quenching the gear shaft with the hanging device of the utility model, the deformation of the carburized and quenched gear shaft can be controlled, so that the rejection rate of the gear shaft is reduced.
Description
Technical field
The utility model relates to a kind of gear shaft carburizing and quenching frock, especially relates to a kind of gear shaft carburizing and quenching erecting by overhang.
Background technology
At present; The erecting by overhang that adopts during the gear shaft carburizing and quenching is an associated plant; The center of this associated plant is a root post, and column lower end is welded with cup dolly, is with the A-frame of two center drillings on the column; Be respectively A-frame and following A-frame, be used for placing two-layer gear shaft up and down; A-frame separates through packing ring, so that adjust the distance of two A-frames, on support, is equipped with circular base slab with holes.During work, gear shaft is inserted in the hole of back up pad, utilize the step of gear shaft, be placed on the back up pad, go into the stove carburizing.The material of this associated plant all adopts the ordinary low-carbon steel manufacturing.Because there is a column at the associated plant center, is with packing ring on the column again, makes associated plant centre portions richness gather great amount of heat; During quenching; Because associated plant centre radiating condition difference and speed of cooling is slow, speed of cooling is fast near associated plant excircle part radiating condition is good, causes gear shaft near cylindrical position and different near the speed of cooling in centre; And generation thermal stresses and structural stress; Thereby make the axle journal position of gear shaft because the thermal stresses when quenching and the existence of structural stress, and produce the teeth directional and the radial deformation of tooth portion, this distortion greater than its tooth portion stay the mill amount after; Then tooth portion can not grind and produces and scraps, and this device is low work-ing life.
The utility model content
The utility model technical problem to be solved is, provide a kind of heating and cooling environmental facies that make each carburized gears axle with, thereby the gear shaft carburizing and quenching erecting by overhang of pinion axle Deformation of Quench-carburizing amount.
The utility model solves the technical scheme that its technical problem adopted: a kind of gear shaft carburizing and quenching erecting by overhang is made up of davit, upper supporting plate, lower carrier plate, base plate and five identical columns; Said davit passes through the centre hole of upper supporting plate and lower carrier plate, and fixes with upper supporting plate, lower carrier plate, base plate welding, and the top of said davit is provided with erection opening; Said five root posts are the hole through being circularly and evenly distributed on upper supporting plate and the lower carrier plate respectively, and fixes with upper supporting plate, lower carrier plate, base plate welding, and the top of said five root posts is concordant with upper supporting plate, the diameter of said five root posts and the equal diameters of davit; Said upper supporting plate is provided with five through holes that are used to place gear shaft that are circularly and evenly distributed, and also on two unequal circumference of diameter, is respectively equipped with equally distributed five oilholes; The structure of said lower carrier plate is identical with the structure of upper supporting plate; Said base plate is provided with four oilholes that are circularly and evenly distributed.
Further, said davit, upper supporting plate, lower carrier plate, base plate and the five preferred 0Cr25Ni20 high strength heat resistant of identical column stainless steels are made.
The advantage of the utility model is: the equal diameters of five root posts and davit, gear shaft evenly are positioned between the column, make the heating condition of each gear shaft the same with cooling conditions, and thermal stresses and structural stress are evenly distributed, and workpiece deformation is little; Be equipped with oilhole on base plate, upper supporting plate and the lower carrier plate,, make that when gear shaft quenched, the speed of cooling at each position equated, thereby makes that the quenching strain of gear shaft is little to increase the flowability of quenching oil; Select the manufacturing of 0Cr25Ni20 high strength heat resistant stainless steel for use, high temperature is difficult for oxidation, and weight capacity is strong, and the high temperature and creep resistance ability is good, so distortion is little, and long service life.
