Description

A kind of fixing structure for pin shaft that can realize exempting from bolt fast assembling-disassembling

Technical field

This utility model is related to a kind of fixing structure for pin shaft, specifically a kind of bearing pin that can realize exempting from bolt fast assembling-disassembling Fixed structure, belongs to mechanical assembly and technique for fixing field.

Background technology

In machinery, bearing pin plays a part of to connect each movable part, forms hinge, and range of application is very wide It is general.Bearing pin is mainly subject to be allowed to the frictional force for rotating and the offset loading force for being allowed to axially movable, and both power need bearing pin to fix Device is offset, so as to playing a part of to prevent eccentric wear and altering axle.Traditional axle fixed form be using bolts assemblies pressing plate and Block, difference are only the geomery and installation form slightly difference of the block of pressing plate.The knot fixed using bolt in general Structure is simple, but must turn round instrument during dismounting by spanner or surely, and (for example excavator needs frequently dismounting is needed Frequently change the situations such as scraper bowl, quartering hammer, hydraulic shear) or the working environment of moist vibration under, bolt be very easy to it is impaired, often Occur that corrosion, thread damage even bolt fracture in screwed hole, often cause to delay work if there is this phenomenon When and be difficult to the serious consequence repaired.

The content of the invention

For the problem that above-mentioned prior art is present, this utility model offer is a kind of can be realized exempting from bolt fast assembling-disassembling Fixing structure for pin shaft, do not adopt completely bolt i.e. be capable of achieving axle fixation, be capable of achieving only hand assembled and without by any work Tool, easy to operate and easy to maintain and replacing.

To achieve these goals, a kind of bearing pin that can realize exempting from bolt fast assembling-disassembling that this utility model is adopted is fixed Structure, including block, clamp I, pin, clamp II and tabletting, the block are fixed at the correct position of bearing, make axle Fixed plate can be embedded in the drop-center of block just；Be provided with chamfering or skewed slot on the both sides outer face of the block, clamp I and Clamp II passes through pin hinges and constitutes hinge leaf, by the subtended angle for adjusting combined hinge hinge, which can be made to be stuck in just gear In the skewed slot of block both sides outer face；Tabletting is fixed with clamp I or clamp II, tabletting can be pressed in when axle is in stationary state In the fixed plate of axle.

Preferably, the clamp I is corresponding with the outside of clamp II is fixed with reinforcing plate I and reinforcing plate II.

Preferably, the tabletting is connected with clamp I or clamp II by spring.

Preferably, the one side of the tabletting is inclined-plane, during installation, by being embedded in then consolidating for axle to the movement of narrower position Between fixed board and clamp I or clamp II.

Compared with existing mounting technology, this utility model has the advantage that：

1st, do not use bolt to complete to assemble and fix, eliminate the accident potential caused because of bolt failure；

2nd, pure hand assembled can be fully achieved, without any instrument；

3rd, suitable for varions type load and vibration working environment and the operating mode of the bearing pin for needing frequently to dismount, range of application Extensively；

4th, simple structure, assembly space demand are little, it is easy to manufacture, and cost is relatively low；

5th, easy to maintain and replacement.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 4, a kind of fixing structure for pin shaft that can realize exempting from bolt fast assembling-disassembling, including block 1, card Plate I3, pin 4, clamp II5 and tabletting 7, the block 1 are fixed at the correct position of bearing 9, enable the fixed plate of axle 8 Just in the drop-center of embedded block 1；Chamfering or skewed slot, clamp I3 and clamp are provided with the both sides outer face of the block 1 II5 is hinged and constitutes hinge leaf by pin 4, by the subtended angle for adjusting combined hinge hinge, which can be made to be stuck in just block 1 In the skewed slot of both sides outer face；Tabletting 7 is fixed with clamp I3 or clamp II5, tabletting 7 can be pressed in when being in axle stationary state In the fixed plate of axle 8.

In order to ensure that there is enough rigidity to be not likely to produce deformation for clamp I3 and clamp II5, as depicted in figs. 1 and 2, can be Clamp I3 is corresponding with the outside of clamp II5 to be fixed with reinforcing plate I2 and reinforcing plate II6.Specifically, reinforcing plate I2 is welded on clamp On I3, reinforcing plate II6 is welded on clamp II5.In addition, as shown in Figure 3 and Figure 4, if work condition environment it is less demanding or The rigidity and intensity of clamp material is enough, it is also possible to do not select reinforcing plate.

As shown in Fig. 2 above-mentioned tabletting 7 can be connected with clamp I3 or clamp II5 by spring.

Before the fixing structure for pin shaft is installed, as depicted in figs. 1 and 2, the fixed plate of axle 8 should be pasted with bearing 9 first Close, while block 1 is fixed at the correct position of bearing 9, make in the drop-center of the embedded block 1 of fixed plate of axle 8.Then Clamp I3 and clamp II5 is hinged and constitutes hinge leaf by pin 4 and is opened, be pressed onto the fixed plate surface of axle 8, after release, Because arranging spring on tabletting 7, hinge leaf is ejected laterally；Meanwhile, the angle of clamp I3 and clamp II5 diminishes, and last two Individual clamp (clamp I3 or clamp II5) end is clamped on block.When axle 8 is outwards jumped by axial force, the fixed plate of axle 8 Hinge leaf can be withstood, causes clamp I3 and the subtended angle of clamp II5 more to reduce, the meeting of such clamp (clamp I3 or clamp II5) Firmly it is stuck in block gap slot, prevents axle from continuing outwards to jump, finally play axle stop and fixation.Under normal state, As spring force is acted on, it is ensured that hinge leaf is not caved in, therefore can guarantee that hinge leaf will not self falling.

Above-mentioned tabletting 7 can also pass through extruding, absorption and the fixation of additive method and clamp (clamp I3 or clamp II5) and axle Plate is contacted.Tabletting 7 is contacted such as Fig. 3 and Fig. 4 institutes with the fixed plate of clamp (clamp I3 or clamp II5) and axle by way of extruding Show.7 beveling of tabletting, during installation, by fixed plate and clamp I3 or clamp that axle 8 is embedded in then to the movement of narrower position Between II5, and adsorb thereon, it is also ensured that hinge leaf plays stop fixation, and will not self falling.

From said structure, this utility model passes through the cooperation of block, clamp I, pin, clamp II and tabletting, no Complete to assemble by reusing bolt and fix, eliminate the accident potential caused because of bolt failure；Can fully achieve pure Hand assembled, without any instrument；The bearing pin that working environment and needs suitable for varions type load and vibration is frequently dismounted Operating mode, applied range；Simple structure, assembly space demand are little, it is easy to manufacture, and cost is relatively low；Easy to maintain and replacement.
