Technical field
The present invention relates to a kind of heat treatment tooling, particularly relate to a kind of for the heat treated gear wheel carburization heat treatment tooling of automobile primary step down gear.
Background technology
At present, in the known gear workpieces processing, gear workpieces comprehensive tooth section and outside dimension carry out final carburizing and quenching, temper after being worked into final dimension again, the favourable turn job shop carries out precision work to inner face and endoporus after carburizing and quenching, the temper, gear workpieces is after periodic atmosphere controllable multi-purpose furnace carburizing and quenching, tempering, the large end face of workpiece toothed portion and workpiece no longer machine adds, but directly installation is used.Usually the frock of carburizing and quenching, temper employing is to make a high temperature steel plane, frock Intermediate Gray square hole, the master is subtracted the gear yaw thereon, adopt the large end face of workpiece as support, its weak point is: gear because playing a supporting role at the large end face position, and makes the large end face distortion overproof in heating and cementation process, so that scrap rate rises, cause manufacturing cost high, management difficulty is large.
Summary of the invention
The object of the invention is to overcome the weak point that exists in the above-mentioned technology, provide a kind of simple in structure, reasonable in design, the gear wheel carburization heat treatment tooling that can in gear carburizing quenching, tempering whole process, use.
In order to achieve the above object, the technical solution used in the present invention is: comprise gear support frame, offer the bracing frame open holes around the described gear support frame, the centre has been evenly arranged a plurality of pillar stiffeners, described pillar stiffener links to each other by supporting floor, and link to each other with the support body frame by supporting floor near the gear support frame boundary, offer the ladder table top and the upper end is provided with chamfering at described pillar stiffener, described chassis is rectangle, and offer the cylindrical frock angle open holes corresponding with the bracing frame open holes all around, evenly offer a plurality of slots on the chassis, lower end, described cylindrical frock angle is provided with round boss near the end, the position that cylindrical frock angle is positioned at the boss below is plugged on cylindrical frock angle open holes, and the position that is positioned at the boss top is serially connected with the layer 1-7 gear support frame successively by the bracing frame open holes.
Advantage of the present invention is:
1. simple in structure, reasonable in design, manufacture difficulty is low;
2. the number of plies of gear support frame can be processed the quantity adjustment of gear as required, and installs simple and direct;
3. but establishment gear heat treatment deformation makes gear still keep the higher accuracy of form and position after Overheating Treatment, and the rate of reducing the number of rejects and seconds is saved cost, increases economic efficiency.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
By Fig. 1-Fig. 6 as can be known, the present invention includes gear support frame 3, offer bracing frame open holes 4 around the described gear support frame 3, the centre has been evenly arranged a plurality of pillar stiffeners 5, described pillar stiffener 5 links to each other by supporting floor 7, and link to each other with support body frame 6 by supporting floor 7 near gear support frame 3 boundaries, offer the ladder table top on the described pillar stiffener 5 and the upper end is provided with chamfering, described chassis 1 is rectangle, and offer the cylindrical frock angle open holes 9 corresponding with bracing frame open holes 4 all around, evenly offer a plurality of slots 10 on the chassis 1,2 lower ends, described cylindrical frock angle are provided with round boss 8 near the end, the position that cylindrical frock angle 2 is positioned at boss 8 belows is plugged on cylindrical frock angle open holes 9, and the position that is positioned at boss 8 tops is serially connected with layer 1-7 gear support frame 3 successively by bracing frame open holes 4.
Described gear support frame 3 is gone up row most and is connected lower row's pillar stiffener 5 and connects by the support floor 7 that is mutually 120 °, and middle pillar stiffener 5 connects by the support floor 7 that is mutually 90 °.
The position that described cylindrical frock angle 2 is positioned at boss 8 tops is the cross-shaped structure.
The present invention puts the pillar stiffener 5 of gear support frame 3 with above the support floor 7 with the gear workpieces 11 of low-carbon alloy steel, gear workpieces 11 adopts by its inner face and supports floor 7 supports, gear workpieces 11 large end faces are unsettled, each pillar stiffener 5 on the gear support frame 3 and support floor 7 are according to gear workpieces 11 inner faces and the uniform design of internal diameter size size, the position that cylindrical frock angle 2 is positioned at boss 8 belows is plugged on cylindrical frock angle open holes 9, the position that is positioned at boss 8 tops is serially connected with layer 1-7 gear support frame 3 successively by bracing frame open holes 4, the levels of gear support frame 3 adopts equally distributed pillar stiffener 5 supports on the gear support frame 3, guarantee that gear workpieces 11 large end face in the processing whole process does not contact this frock, thoroughly eliminated the in the past passive operating mode of gear workpieces 11 end faces, avoided heating up, heating, in the insulating process, because making workpiece, frock distortion itself under the condition of high temperature, causes the overproof problem of large end face distortion.
This tooling combination uses, at first cylindrical frock angle 2 is fastened in the One On The Chassis a plurality of cylindrical frocks angle open holes 9, chassis 1 is rectangle, the oblong aperture of uniform some amount on large chassis, gear support frame 3 is set on the cylindrical frock angle 2 again, gear support frame 3 has namely been put on the chassis 1 successively like this, and the position that cylindrical frock angle 2 is positioned at boss 8 tops is the cross-shaped structure, is of value to gear support frame 3 and is set on the cylindrical frock angle 2.Gear support frame 3 is rectangles, offer bracing frame open holes 4 around the gear support frame 3, the centre has been evenly arranged a plurality of pillar stiffeners 5, pillar stiffener 5 links to each other by supporting floor 7, and link to each other with support body frame 6 by supporting floor 7 near gear support frame 3 boundaries, go up most row and be connected lower row's pillar stiffener 5 and connect by the support floor 7 that is mutually 120 °, middle pillar stiffener 5 connects by the support floor 7 that is mutually 90 °.Offer ladder table top and upper end on the pillar stiffener 5 and be provided with chamfering, make things convenient for flowing of liquid medium.
This frock is after a kind of gear with low-carbon alloy steel installs on this frock, sent in the atmosphere controllable multi-purpose furnace by truck, in active (methyl alcohol, nitrogen, acetone) medium, heat up heating, under about 920 ℃, be incubated for a long time (soaking time is selected according to carburized depth), make active atoms of carbon infiltrate workpiece surface, so that workpiece surface obtains high carbon content, and then workpiece surface obtains the cementation zone of high hardness and wear resistance, and the heart section of workpiece has high obdurability.
Technical essential of the present invention is to guarantee that gear large end face in heat treatment process does not contact frock, and it is minimum and regular to reach after the thermal treatment amount of distortion, and the whole service requirements of gear is satisfied in accuracy requirement.
