Description

Pin shaft mounting structure and the engineering machinery with it

Technical field

The utility model is related to a kind of pin shaft mounting structure and the engineering machinery including the mounting structure.

Background technology

Bearing pin acts primarily as the effect of connection adjacent component and transmission load as the work accessory of engineering machinery, if pin Axle failure will cause the resistance of motion to increase, and the discharge height or distance of engineering machinery does not reach a series of of rated value and ask Topic, the action value of bearing pin has some idea of.There are two aspects to require bearing pin in actual production and operation：

First, the requirement of working method, because the parts rotating motion of equipment is all using bearing pin as the centre of gyration, because Requirement in this working method from bearing pin to bearing pin has：1st, bearing pin can not be rotated with the gyration of adjacent component, otherwise The function of transmission load is lost while unstable wear；2nd, bearing pin can not be in tie point axial float, in case shotpin axle comes off.

2nd, the requirement of production and application, due to engineering machinery, often work under bad environment, operating mode are complicated, and bearing pin is easily excessive Abrasion or even failure, belong to easily loss, the accessory of frequency replacing.Therefore, the requirement from the angle of production and application to bearing pin has：1st, hold Easy production and processing, simple structure, to reduce production and consumables cost, this explanation should be with as far as possible for the improvement of bearing pin Simplification is as design direction rather than more complicated better；2nd, it is easy for installation, it is easy to change, do not affect the operating efficiency of engineering machinery. 3rd, intensity is kept, bearing pin is not suitable for making the cylindrical shape of its integrative-structure substantially change as bearing part, otherwise will reduce Its intensity causes fracture.

Most currently used pin shaft structure be patent No. CN201420635101.1 utility model patent, its principle be One end face of bearing pin is welded with otic placode, and pushing down bearing pin by otic placode prevents axial float, and because otic placode and bearing pin are integrated Structure, when otic placode is bolted on workpiece, bearing pin also will not rotate.The major defect of this structure is：Ear Plate necessarily has single operation to manufacture as single component, including casting, polishing etc., in this process, except manufacture Otic placode needs single consumptive material, and these operations all increase corresponding production cost, and to ensure that otic placode and the size of bearing pin are matched somebody with somebody Set, product percent of pass is impacted.Alignement is also required to during installation and removal, and it is inconvenient.And in the prior art Around some improvement that the patent is made, this defect is not preferably overcome.

Utility model content

To overcome drawbacks described above, the utility model to disclose a kind of pin shaft mounting structure and the engineering machinery with it, the party Case reduces bearing pin production consumptive material on the premise of bearing pin is met using function, greatly, reduces production process, reduces producing into This, and relative to prior art, mounting means more simple and flexible, replacing is convenient.The technical scheme that the utility model is taken For：A kind of pin shaft mounting structure, including bearing pin and fixed plate, open up the installing hole for installing bearing pin, on the bearing pin in fixed plate Alignment pin is provided with, installing hole edge has positioning port corresponding with the alignment pin, and the pin shaft mounting structure also includes Securing member, on the fastener hole that fixed plate is opened up, the egative film of securing member pushes down the end face and/or positioning of bearing pin to fasteners tight Pin.

Further, pin-and-hole is offered on the bearing pin, the alignment pin is assigned in pin-and-hole.

The utility model discloses a kind of engineering machinery simultaneously, and the engineering machinery includes described pin shaft mounting structure.

Taking the advantage of above-mentioned technical proposal has：1st, bearing pin processing mode is more simple, cost is lower, it is not necessary to amount of production Outer component coordinates, and saves consumptive material, reduces operation；2nd, easy installation and removal, it is only necessary to screw or loosening pressed bearing pin fastening Part, it is possible to complete installation and removal；3rd, bearing pin contour structures are maintained, bearing pin intensity is constant, and bearing capacity is good.4th, bearing pin application When engineering machinery, due to embedded design, product is more succinct attractive in appearance.4th, other use advantage referring to specific embodiment.

Specific embodiment

With reference to shown in Fig. 1, Fig. 2, a kind of pin shaft mounting structure, including bearing pin 1 and fixed plate 2a, 2b, fixed plate 2a, on 2b Installing hole 3a, the 3b for installing bearing pin 1 is opened up, pin-and-hole 7 is opened up on the bearing pin 1, alignment pin 4 is assigned in pin-and-hole 7, installing hole 3a Edge has positioning port 5 corresponding with the alignment pin 4, and the pin shaft mounting structure also includes securing member 6, and securing member 6 revolves Tightly on the fastener hole 62 that fixed plate 2a is opened up, the egative film 61 of securing member pushes down the end face and/or alignment pin 4 of bearing pin 1.

When using, alignment pin 4 is inserted in pin-and-hole 7, then bearing pin is corresponding in fixed plate, alignment pin 4 and peace The engaging of positioning port 5 on dress hole can be in case shotpin axle be rotated；Again because the egative film 61 of securing member pushes down alignment pin 4, you can with Bearing pin play is prevented, use demand and convenient dismounting is met.Processing request very simple of this structure to bearing pin, only need to be in pin Drill on axle, cost and difficulty of processing are far below in prior art and need the technical schemes such as welding or split casting, It is also to loosen securing member during dismounting, reduces dismounting and change difficulty.

A kind of other side of the present utility model, there is provided engineering machinery, including loading machine, fork truck, excavator, the work , including the pin shaft mounting structure described in above-mentioned technical proposal, used as consumable accessory, the engineering machinery is in operation for bearing pin for journey machinery Need to use in a large number and frequently change, therefore the engineering machinery using this pin shaft mounting structure will more Jing in use cost Ji, it is more convenient in maintenance and repair, quick.
