Abstract
The utility model belongs to engineering machinery field, more particularly to a kind of mounting structure of loading machine large arm and axle sleeve, the axle sleeve is divided into the sleeve and locknut threadably connected, sleeve is assemblied in from the side of large arm in the axis hole of large arm, and locknut is tightened on prevention axle sleeve axial displacement on sleeve from large arm opposite side.This mode changes axle sleeve and welding procedure is taken to be fixed on the traditional handicraft in large arm, is effectively improved the concentricity and the depth of parallelism of axle sleeve, improves production efficiency, enhances product performance simultaneously.
Description
Technical field
The utility model belongs to mechanical manufacturing field more particularly to the mounting structure of a kind of loading machine large arm and axle sleeve.
Background technology
Axle sleeve in existing loading machine large arm is all that axle sleeve is welded in large arm axis hole with welding manner, it is therefore an objective to be
Make the axis pin being mounted in axle sleeve at work, axle sleeve do not loosen.But the mounting structure of this large arm and axle sleeve exists
Following drawback：1st, when axle sleeve is welded on axis hole by existing way as a whole, it is difficult to which the angle of accurate sleeve and axis hole causes same
Several sleeve concentricities, parallelism tolerance in one large arm is inconsistent；Variation is also be easy to cause to axle sleeve aperture after welding, is caused
Machining accuracy reduces；The mode of welding can also cause large arm to deform, these consequences often make axle sleeve positioning inaccurate so as to add
The friction of bushing and axle sleeve inside acute axis pin and axis pin increases number of rewelding and maintenance cost；2nd, manufacture is complicated, original welding
Mode has higher requirements to the Weldability of operating personnel, and manufacture efficiency is low, can not realize automated production；3rd, welding manner is made
It is difficult to detach with large arm into axle sleeve, it has not been convenient to repair, hardness, which is removed, can reduce the armor plate strength at axis hole, increase vehicle rear
Risk is scrapped in continuous use.
Utility model content
To overcome above-mentioned technological deficiency, the utility model discloses the mounting structure of a kind of loading machine large arm and axle sleeve, this reality
It is with the novel technical solution taken, a kind of mounting structure of loading machine large arm and axle sleeve, the axle sleeve is divided into threadably
The sleeve and locknut of connection, sleeve are assemblied in from the side of large arm in the axis hole of large arm, and locknut is tightened on set from large arm opposite side
Axle sleeve axial displacement is prevented on cylinder.
Further, the mounting structure of loading machine large arm described in the utility model and axle sleeve, axle sleeve is to be interference fitted
Mode is assemblied in the axis hole of large arm.
Further, the mounting structure of loading machine large arm described in the utility model and axle sleeve, the diameter of the locknut are big
In the shaft hole diameter.
Further, the mounting structure of loading machine large arm described in the utility model and axle sleeve is equipped in the sleeve
Bushing.
The utility model is changed fixed form of the axle sleeve as an integral solder in large arm in the past, takes split
Composite structure, the effect of acquirement have, and production and processing is simple, originally need manually with personal experience and the welding manner of technical merit
Completely substituted, this structure can be allowed to adapt to workshop integrated automation, unmanned producing line from assembling is worked into；Axle sleeve positions
Precisely, the verticality of axle sleeve and concentricity are promoted, and bushing positioning caused by avoiding welding manner is not allowed and what large arm deformed lacks
It falls into；Using elastic conjunction mode, axle sleeve fixing intensity, and intensity also reaction can be further increased than original welding manner
The angle for making axle sleeve is more accurate；Under the premise of intensity and accuracy are all promoted, stability during vehicle operation is increased, is carried
High service life, and make car body more aesthetically pleasing.
Description of the drawings
Fig. 1 is the utility model assembling exploded view.
Specific embodiment
As shown in Figure 1, the mounting structure of a kind of loading machine large arm and axle sleeve, the axle sleeve is divided into what is threadably connected
Sleeve 1 and locknut 2, sleeve 1 are assemblied in from the side of large arm 3 in the axis hole 4 of large arm, and locknut 2 is tightened on set from large arm opposite side
Axle sleeve axial displacement is prevented on cylinder 1.
Further, the mounting structure of a kind of loading machine large arm of the utility model and axle sleeve, side of the axle sleeve to be interference fitted
Formula is assemblied in the axis hole 4 of large arm.
Further, the mounting structure of a kind of loading machine large arm of the utility model and axle sleeve, the diameter of the locknut 2 are more than
The shaft hole diameter.
Further, the mounting structure of a kind of loading machine large arm of the utility model and axle sleeve is equipped with lining in the sleeve
Set（It is not shown in figure）.
