Abstract
The utility model discloses a fixing device for fixing a pin roll. The fixing device for fixing the pin roll comprises the pin roll and a lug seat, a fixing sleeve is welded on the lug seat, the pin roll penetrates through the lug seat, one end of the pin roll is inserted into the fixing sleeve, and the other end of the pin roll is fixed by a stopper. The fixing device for fixing the pin roll enables the pin roll to keep still when other rotatable parts rotate so as to protect the lug seat and a reinforcing plate from abrasion and prolong service life of the lug seat and the reinforcing plate.
Description
Technical field
The utility model relates to a kind of fixing device, is a kind of fixing device that is used for fixing bearing pin specifically.
Background technique
At present, it all is circular that bearing pin is generally the left and right sides, and realizes that bearing pin keeps motionless when other rotatable parts rotate; What use is the axle head baffle plate; Bearing pin can rotate when when heavy duty rotated at other rotatable parts, and the bolt of stationary axle end-stopping plate can be damaged, and the bearing pin under the local function will rotate like this; Otic placode and stiffening plate can wear and tear, and change otic placode and stiffening plate and will cause bigger economic loss.
The model utility content
The utility model has been invented a kind of fixing device that is used for fixing bearing pin to the deficiency of existing technology, can make bearing pin when other rotatable parts rotate, keep motionless, thereby protection otic placode and stiffening plate does not does not wear and tear, and prolong the working life of otic placode and stiffening plate.
Technological scheme of the present invention is: a kind of fixing device that is used for fixing bearing pin; Comprise bearing pin, ear seat; Two ear seats weld as required, and fixed cover is welded on one of them ear seat, and bearing pin passes two ear seats and bearing pin one end inserts fixed cover; Fixed by fixed cover, the bearing pin the other end is fixed with retainer.
And, the described fixing device that is used for fixing bearing pin, wherein, described fixed cover endoporus is square, and the end that bearing pin inserts fixed cover be square with the equal size of fixed cover endoporus, and the other end of bearing pin is a circle.
And, the described fixing device that is used for fixing bearing pin, wherein, the square length of side of described fixed cover endoporus need equal the diameter of bearing pin, if square cornerwise length axial float can take place during less than the diameter of bearing pin.
And, the described fixing device that is used for fixing bearing pin, wherein, described ear seat is an otic placode.
And, the described fixing device that is used for fixing bearing pin, wherein, described ear seat is to be welded on the otic placode by stiffening plate to constitute.
And, the described fixing device that is used for fixing bearing pin, wherein, described retainer is used for fixing bearing pin, can fix for round nut during heavy duty, can use cotter pin to fix during underloading.
The present invention realizes that bearing pin keeps motionless when other rotatable parts rotate owing to adopted technique scheme, thereby protection miscellaneous part ear seat does not does not wear and tear, and prolongs the working life of ear seat.
Description of drawings
Fig. 1 is the plan view of the utility model.
Fig. 2 is the left view of the utility model.
Left view when Fig. 3 is the application of the described a kind of fixing device that is used for fixing bearing pin of the utility model on the digging type loader.
Fig. 4 is the A-A face sectional view of Fig. 3.
Wherein, fixed cover 1, bearing pin 2, otic placode 3, stiffening plate 4, round nut are with lock washer 5, round nut 6, base 7, oil cylinder 8, revoliving arm otic placode 9, oil cylinder ear muff 10, pin sleeve 11.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The technological scheme that the utility model provided does, all is welded with the ear seat in the both sides of base 7, and the ear seat can be made up of otic placode 3 separately; Also can be welded on the otic placode 3 by stiffening plate 4, fixed cover 1 is welded on one of them stiffening plate 4, and the endoporus of fixed cover is square; Bearing pin 2 one ends are that a square end is circle, and bearing pin 2 passes two ear seats, and a square end inserts in the fixed cover 1 and fixed by fixed cover; The other end of bearing pin is fixed with lock washer 5, round nut 6 by round nut, and this structure can guarantee that just bearing pin has good fixed effect, and bearing pin is motionless when miscellaneous part rotates; Thereby protected stiffening plate and otic placode, made it be difficult for being worn.
And the end that bearing pin 2 inserts fixed covers 1 be square with the equal size of fixed cover endoporus, and the square length of side of fixed cover endoporus equals the diameter of bearing pin, axial float can take place as if square cornerwise length during less than the diameter of bearing pin.
Fig. 3 and Fig. 4 are a kind of application of fixing device on the digging type loader that is used for fixing bearing pin; Fixed cover 1 is welded on pin sleeve 11 on one of them; Revoliving arm and otic placode weld together and constitute revoliving arm otic placode 9, and pin sleeve 11 is welded on the revoliving arm otic placode 9, and bearing pin passes fixed cover 1, pin sleeve 11, oil cylinder ear muff 10; Bearing pin one end is fixed by fixed cover; The bearing pin the other end is fixing with lock washer 5 with round nut 6, round nut, and fixed cover prevents the radial motion of bearing pin, and round nut and round nut prevent the axial float of bearing pin with lock washer.
Oil cylinder ear muff 10 is links of oil cylinder 8 and bearing pin, is fixed together with oil cylinder 8, and pin sleeve 11 is links of revoliving arm otic placode 9 and bearing pin, welds together with revoliving arm otic placode 9.It is fixing that fixed cover 1 makes bearing pin 2 when oil cylinder 8 and revoliving arm otic placode 9 relatively rotate; Realize that oil cylinder 8 bearing pin when promoting revoliving arm otic placode 9 keeps motionless with respect to otic placode 3, pin sleeve 11; Thereby protection revoliving arm otic placode 9, pin sleeve 11 do not move wearing and tearing, prolong the working life of revoliving arm otic placode 9, pin sleeve 11.
And the end that bearing pin 2 inserts fixed covers 1 be square with the equal size of fixed cover endoporus, and the square length of side of fixed cover endoporus equals the diameter of bearing pin, axial float can take place as if square cornerwise length during less than the diameter of bearing pin.
Above embodiment only supplies to explain the usefulness of the utility model, but not to the restriction of the utility model, the technician in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or variation.Therefore, all technological schemes that are equal to also should belong to the category of the utility model, should be limited each claim.
