Description

A kind of nitriding furnace special hoisting utensil

Technical field

The utility model belongs to hoisting machinery processing units field, particularly a kind of nitriding furnace special hoisting utensil.

Background technology

Gear is considerable parts in wheel casing, the assembly precision of wheel casing, directly affects quality product and the serviceability of whole electric block.In the past, gear is in nitridation process, there is no special frock, mostly workpeople, in gear heat treatment process, is to adopt artificial and easy auxiliary means to process, this method, namely inconvenient, also dangerous, be difficult to again ensure the quality of products, therefore need a set of special utensil of design to carry out this procedure auxiliary.

Summary of the invention

The utility model for solve in known technology the technical problem that exists and provide a kind of structure simple, make easy, easy to use, time saving and energy saving, efficiency is higher, assembly quality guaranteed nitriding furnace special hoisting utensil.

The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:

A kind of nitriding furnace special hoisting utensil, it is characterized in that: comprise cage assembly, hook assembly, wherein said cage assembly is mounted on hook assembly, described cage assembly comprises upper base circle, lower foundation ring, main pillar, the circumferential direction of described upper base circle is welded with round bar, described upper round bar extends to upper base circle center and welds with main pillar, between the outer end of upper round bar and lower foundation ring, be welded with lateral brace; Described lower foundation ring is radially provided with lower web plate, and described lower web plate and main pillar weld together, between the lower web plate that circumferential direction is adjacent, be welded with quarter butt and stock; Described hook assembly comprises plectane, and the upper surface central position of described plectane is welded with suspension ring, and the lower surface of described plectane is welded with suspension hook near outer fringe position, and the upper surface of described plectane is arranged with two handles, is outwards provided with bending in the upper end of handle.

The advantage that the utility model has and positively effect are: because the utility model scientific structure design is reasonable, structure is simple, simple and efficient to handle, stability is strong, realize gear engages steadily in speed reduction unit, gear Contact precision is high, prevent gear shifting quadrant texturing, ensure that gear nitriding result is good, layer depth is even, quality product is guaranteed, improves assembly precision and the total quality of speed reduction unit; Also can reduce error simultaneously, enhance productivity.Easy to use, time saving and energy saving, reduce workman's working hour in high temperature environments.

Embodiment

For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1 to Fig. 5, a kind of nitriding furnace special hoisting utensil, comprise cage assembly 1, hook assembly 2, wherein said cage assembly 1 is mounted on hook assembly, described cage assembly comprises upper base circle 1-1, lower foundation ring 1-2, main pillar 1-3, the circumferential direction of described upper base circle is welded with round bar 1-4, and described upper round bar extends to upper base circle center and welds with main pillar, between the outer end of upper round bar 1-4 and lower foundation ring, be welded with lateral brace 1-5; Described lower foundation ring 1-2 is radially provided with lower web plate 1-8, and described lower web plate 1-5 and main pillar 1-3 welds together, and is welded with quarter butt 1-6 and stock 1-7 between the lower web plate that circumferential direction is adjacent; Described hook assembly 2 comprises plectane 2-1, the upper surface central position of described plectane is welded with suspension ring 2-2, the lower surface of described plectane is welded with suspension hook 2-3 near outer fringe position, and the upper surface of described plectane is arranged with two handles 2-4, is outwards provided with bending 2-40 in the upper end of handle.Above-mentioned part is welded by high temperature steel Cr25Ni20Si2, has higher hot strength and oxidation-resistance, and cage steadily can be put into nitriding furnace by suspension hook, prevents from rocking swinging colliding with of causing.

The utility model scientific structure design is reasonable, structure is simple, simple and efficient to handle, stability is strong, realize gear engages steadily in speed reduction unit, gear Contact precision is high, prevent gear shifting quadrant texturing, ensure that gear nitriding result is good, layer depth is even, quality product is guaranteed, improves assembly precision and the total quality of speed reduction unit; Also can reduce error simultaneously, enhance productivity.Easy to use, time saving and energy saving, reduce workman's working hour in high temperature environments.

Principle of work of the present utility model is as follows:

When carrying out gear nitrogenize, master wheel is put into cage, hook cage slowly puts into nitriding furnace, two handles of suspension hook, can manual decoupling device, prevents personnel from scalding, and suspension hook adopts clockwise direction welding, is convenient to set out.Because jug can be held up, during suspension hook lifting, shaking amplitude is little, can avoid colliding with nitrogenize furnace wall, stable gear is put into nitriding furnace safely, so carrying out nitriding treatment to gear, both convenient, safety, can ensure thermal treatment quality again.

The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
