Abstract

The utility model relates to a hanger for crankshaft normalizing, which comprises a hanging rod (1), an upper beam plate (2), suspenders (3) and a lower hanger plate (4), wherein the left and the right sides of the lower hanger plate (4) are provided with symmetrical U-shaped holding notches (41) for hanging crankshafts, the edges of the U-shaped holding notches (41) are shaped like spigot steps, and the U-shaped holding notches (41) are provided with cooperating U-shaped holding rings (5). Because the diameters of the holding openings of the U-shaped holding notches (41) can be changed by the U-shaped holding rings (5), the hanger can meet the requirement for hanging a variety of crankshafts.

Description

Suspension bracket is hung in the bent axle normalizing

Technical field

The utility model relates to the normalizing furnace suspender, is a kind of bent axle suspension suspension bracket that is used for bent axle is carried out normalizing treatment.

Background technology

Bent axle needs to carry out normalizing treatment with normalizing furnace after forging out, will hang over bent axle during the bent axle normalizing and hang on the suspender, and bent axle enters the normalizing furnace heating together in company with suspender bent axle is carried out normalizing treatment.It all is oneself design that existing bent axle hangs each manufacturer of suspension bracket, pattern is varied, because the bent axle kind is more, the axle journal size of different bent axles is also inequality, so when changing bent axle, needing to change suspender simultaneously, all is to adopt high heat-resisting non-shrinking steel to make owing to be subjected to temperatures involved, suspender, cost is higher, and the suspender dead weight is heavier, and the positive live wire of suspension has a lot of suspenders, and replacing is wasted time and energy.

The utility model content

The utility model purpose provides a kind of bent axle normalizing of highly versatile and hangs suspension bracket, hangs suspension bracket specification kind to reduce, and saves the suspender cost, reduce and hang the suspension bracket replacing, reduce labour intensity, enhance productivity, realize that the different varieties bent axle is hung normalizing to be used.

The normalizing of the utility model bent axle is hung suspension bracket by peg 1, last beam slab 2, suspension rod 3, following boatswain chair 4 is formed, peg 1 upper end is to be connected with transmission chain, peg 1 lower end is connected with last beam slab 2, last beam slab 2 and following boatswain chair 4 shape correspondences, four edges (on the cross centre line) symmetry at last beam slab 2 and following boatswain chair 4 offers open type suspension rod draw-in groove or suspension rod installation perforation 20,40, following boatswain chair 4 is connected by suspension rod 3 with last beam slab 2, left and right sides symmetry offers and is used to the U-shaped draw-in groove 41 that card hangs bent axle on following boatswain chair 4, the edge of U-shaped draw-in groove 41 is a stopping table shape, on this U-shaped draw-in groove 41, cooperate and be provided with U-shaped snap ring 5, by the bayonet socket diameter of U-shaped snap ring 5 change U-shaped draw-in grooves 41, to adapt to the axle journal size of different bent axle A.

It is simple that hanger structure is hung in the normalizing of the utility model bent axle, easily manufactured, simple and convenient assembly, be designed to the U-shaped snap ring 5 of different internal orifice warps at different axle journals, when the bent axle extension that is used for different big pilot pins hangs use, only need to change corresponding U-shaped snap ring 5 and cooperate, be easy to installation and removal, satisfy the user demand that many kinds bent axle is hung with the axle journal of bent axle.
