Description

Crankshaft hanging tempering lifting appliance for non-road

Technical Field

The utility model relates to an industrial manufacturing field, the hoist and mount and processingequipment of a bent axle specifically says so.

Background

The non-road crankshaft is produced in a periodic furnace in a conventional heat treatment mode at home and abroad, a trolley furnace is adopted for quenching and tempering so as to meet the requirements of technical indexes such as mechanical property, metallographic structure, straightness and the like of the non-road crankshaft, a tool three-point supporting main journal is adopted when the original non-road crankshaft is quenched and tempered in the trolley furnace, and a special lifting appliance is used for lifting and quenching during quenching.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a non-road hangs quenching and tempering hoist with bent axle.

The specific technical scheme is as follows:

the utility model provides a non-road hangs quenching and tempering hoist with bent axle, sets up a skip hanging beam, the skip hanging beam passes through the skip pull rod fixed, the plane department of skip hanging beam sets up spacing arch, still set up the breach on the skip hanging beam equally, the breach is connected with the locating lever, the locating lever sets up to crank arm structure, still with hanger connection simultaneously with the U type tray that the locating lever bottom is connected, the hanger erects on the skip hanging beam and is limited the displacement by spacing arch on the skip hanging beam, the plane department of U type tray sets up U type ladder notch, the inside bent axle that is used for placing of U type ladder notch, the central line of two locating levers and the central line department of bent axle are on the coplanar, just the central line of bent axle with the coaxial setting of skip pull rod.

In order to ensure that the crankshaft smoothly enters the U-shaped tray, the U-shaped tray is arranged at the inlet of the crankshaft in a rounding way.

The utility model has the advantages that: the hoist structure life cycle is easily changed after expiring, and the hoist and mount mode is simple.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a bottom view of fig. 1.

Detailed Description

The utility model discloses below combine the figure specifically to explain the utility model discloses, as shown in the figure, a non-road hangs quenching and tempering hoist with bent axle sets up a skip hanging beam 1, the skip hanging beam passes through skip pull rod 2 fixedly, the plane department of skip hanging beam sets up spacing arch 3, still equally divide on the skip hanging beam and set up breach 4, the breach is connected with locating lever 5, the locating lever sets to bent arm structure, still is connected with gallows 7 simultaneously with U type tray 6 of being connected bottom the locating lever, the gallows erects on skip hanging beam 1 and by spacing arch 3 restriction displacement on the skip hanging beam 1, the plane department of U type tray sets up U type ladder notch 8, the inside bent axle 9 that is used for placing of U type ladder notch, the central line of two locating levers is located on the coplanar with the central line of bent axle, just the central line of bent axle with the coaxial setting of skip pull rod 2.

In order to ensure that the crankshaft smoothly enters the U-shaped tray, the U-shaped tray is arranged at the inlet 10 of the crankshaft in a rounding way.

The utility model has the advantages that: the central lines of the two positioning rods and the central line of the crankshaft are on the same plane, the crankshaft and the pull rod are concentric, so that the balanced stress of the skip after the crankshaft is hung is ensured, the crankshaft keeps vertical suspension in the furnace, and the stress of the front and rear hanging frames is reduced by the positioning rods so as to prevent the hanging frames from being elongated and deformed; the U-shaped stepped notch corresponds to the manipulator, so that the crankshaft is easy to assemble and disassemble, the device simplifies the crankshaft hoisting mode, can realize crankshaft suspension hardening and tempering automation, and ensures that the heating and quenching states of each crankshaft are consistent; the straightness qualified rate of the quenched and tempered crankshaft is greatly improved because the hoisting position is the main journal of the crankshaft; meanwhile, the hanging bracket, the positioning rod and the tray are more convenient to replace after the service life of the whole structure is over.

Claims

1. The utility model provides a non-road hangs quenching and tempering hoist with bent axle, sets up a skip hanging beam, its characterized in that: the skip hanging beam is fixed through a skip pull rod, a limiting bulge is arranged at the plane of the skip hanging beam, notches are further uniformly arranged on the skip hanging beam and are connected with positioning rods, the positioning rods are arranged to be crank arm structures, a U-shaped tray connected with the bottom of the positioning rods is also connected with a hanging frame, the hanging frame is erected on the skip hanging beam and is limited in displacement by the limiting bulge on the skip hanging beam, a U-shaped stepped notch is arranged at the plane of the U-shaped tray, a crankshaft is placed inside the U-shaped stepped notch, the central lines of the two positioning rods and the central line of the crankshaft are located on the same plane, and the central line of the crankshaft and the skip pull rod are coaxially arranged.

2. The crankshaft hanging tempering spreader for the non-road according to claim 1, characterized in that: in order to ensure that the crankshaft smoothly enters the U-shaped tray, the U-shaped tray is arranged at the inlet of the crankshaft in a rounding way.
