Description
Technical field
The present invention relates to a kind of heat treatment tooling, particularly relate to a kind of for the heat treated Gear carburization thermal treatment tool of automobile primary step down gear.
Background technology
At present, in known gear workpieces processing, the comprehensive teeth portion of gear workpieces and outside dimension carry out final carburizing and quenching, temper after being worked into final dimension again, the job shop that makes a connection after carburizing and quenching, temper carries out precision work to inner face and endoporus, 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 use of directly installing.The frock that usual carburizing and quenching, temper adopt is making high temperature steel plane, frock Intermediate Gray square hole, master is subtracted gear yaw thereon, adopt the large end face of workpiece as support, its weak point is: gear heating and cementation process in because playing a supporting role at large end face position, and make large end face distort overproof, make scrap rate increase, cause manufacturing cost high, management difficulty is large.
Summary of the invention
The object of the invention is to overcome the weak point existed in above-mentioned technology, provide a kind of structure simple, reasonable in design, the Gear carburization thermal treatment tool that can use in gear carburizing quenching, tempering whole process.
In order to achieve the above object, the technical solution used in the present invention is: comprise gear support frame, described gear support frame surrounding offers bracing frame open holes, centre has been evenly arranged multiple pillar stiffener, described pillar stiffener is connected by supporting floor, and be connected with support body frame by supporting floor near gear support frame boundary, described pillar stiffener offers ladder table top and upper end is provided with chamfering, described chassis is rectangle, and surrounding offers the cylindrical frock angle open holes corresponding with bracing frame open holes, chassis evenly offers multiple slot, described lower end, cylindrical frock angle is provided with round boss near end, the position be positioned at below boss, cylindrical frock angle is plugged on cylindrical frock angle open holes, the position be positioned at above boss is serially connected with layer 1-7 gear support frame successively by bracing frame open holes.
Advantage of the present invention is:
1. structure is simple, reasonable in design, and manufacture difficulty is low;
2. the number of plies of gear support frame can process the quantity adjustment of gear as required, and installs simple and direct;
3. can effectively suppress gear heat treatment to be out of shape, make gear still keep the higher accuracy of form and position after Overheating Treatment, rate of reducing the number of rejects and seconds, cost-saving, increase economic efficiency.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
From Fig. 1-Fig. 6, the present invention includes gear support frame 3, described gear support frame 3 surrounding offers bracing frame open holes 4, centre has been evenly arranged multiple pillar stiffener 5, described pillar stiffener 5 is connected by supporting floor 7, and be connected with support body frame 6 by supporting floor 7 near gear support frame 3 boundary, described pillar stiffener 5 offers ladder table top and upper end is provided with chamfering, described chassis 1 is rectangle, and surrounding offers the cylindrical frock angle open holes 9 corresponding with bracing frame open holes 4, chassis 1 evenly offers multiple slot 10, described lower end, cylindrical frock angle 2 is provided with round boss 8 near end, the position be positioned at below boss 8, cylindrical frock angle 2 is plugged on cylindrical frock angle open holes 9, the position be positioned at above boss 8 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 descended the pillar stiffener 5 of row most and be connected by the support floor 7 being mutually 120 °, and middle pillar stiffener 5 is connected by support floor 7 in 90 ° mutually.
The described position be positioned at above boss 8, cylindrical frock angle 2 is cross-shaped structure.
The present invention be the gear workpieces 11 of low-carbon alloy steel is put gear support frame 3 pillar stiffener 5 and support above floor 7, gear workpieces 11 adopts support floor 7 to support by its inner face, gear workpieces 11 large end face is unsettled, each pillar stiffener 5 on gear support frame 3 and support floor 7 are according to gear workpieces 11 inner face and the uniform design of internal diameter size size, the position be positioned at below boss 8, cylindrical frock angle 2 is plugged on cylindrical frock angle open holes 9, the position be positioned at above boss 8 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 on gear support frame 3 to support, ensure that gear workpieces 11 large end face in processing whole process does not contact this frock, completely eliminate the passive operating mode of gear workpieces 11 end face in the past, avoid in intensification, heating, in insulating process, because frock distortion itself makes workpiece cause large end face to be out of shape overproof problem at high operating temperatures.
This tooling combination uses, first cylindrical frock angle 2 is fastened in the One On The Chassis multiple cylindrical frock angles open holes 9, chassis 1 is rectangle, the oblong aperture of uniform some amount on large chassis, again gear support frame 3 is set on cylindrical frock angle 2, namely such gear support frame 3 has been put on chassis 1 successively, and the position that cylindrical frock angle 2 is positioned at above boss 8 is cross-shaped structure, is of value to gear support frame 3 and is set on cylindrical frock angle 2.Gear support frame 3 is rectangles, gear support frame 3 surrounding offers bracing frame open holes 4, centre has been evenly arranged multiple pillar stiffener 5, pillar stiffener 5 is connected by supporting floor 7, and be connected with support body frame 6 by supporting floor 7 near gear support frame 3 boundary, go up most row and descend the pillar stiffener 5 of row most and be connected by the support floor 7 being mutually 120 °, middle pillar stiffener 5 is connected by support floor 7 in 90 ° mutually.Pillar stiffener 5 offers ladder table top and upper end is provided with chamfering, facilitate the flowing of liquid medium.
This frock is that a kind of gear by low-carbon alloy steel installs to after in this frock, send in atmosphere controllable multi-purpose furnace by truck, in active (methyl alcohol, nitrogen, acetone) medium, carry out intensification heating, under about 920 DEG C, carry out long-time heat preservation (soaking time is selected according to carburized depth), active atoms of carbon is made to infiltrate workpiece surface, workpiece surface is made to obtain high carbon content, and then workpiece surface obtains high hardness and the cementation zone of wear resistance, and the heart portion of workpiece has high obdurability.
Technical essential of the present invention is to ensure that gear large end face in heat treatment process does not contact frock, and after reaching thermal treatment, amount of distortion is minimum and regular, and accuracy requirement meets the overall service requirements of gear.
