The utility model belongs to the technical field of the large -scale production auto repair in mine, especially relate to a hole of axis base locator is fixed to large -scale production car railway carriage. It is by leading to the axle, well spacer sleeve, and a set of adjusting washer, location spacer, retaining ring and nut are formed, lead to the axle and comprise with the threaded connection section middle optical axis section, location optical axis section, and well spacer sleeve is connected for clearance fit with middle optical axis section, and a set of adjusting washer draws close the tip at well spacer sleeve, and location spacer and retaining ring overlap logical epaxial in proper order, nut and logical threaded connection section threaded connection, the utility model has the advantages that: can guarantee the fixed hole of axis base's of large -scale production car railway carriage concentricity, the error of avoiding leaning on the judgement of artifical naked eye to produce improves maintenance efficiency, prolongs its related parts's life and simple manufacture, convenient to use, and it is easy to dismantle, low to operating personnel's technical merit requirement, reduces cost of maintenance.
Description
Technical field
The utility model belongs to the technical field of the large-scale production auto repair in mine, particularly relates to a kind of large-scale production truck body stationary axle bore positioning work piece.
Background technique
Often there is wear phenomenon in large-scale production truck body axle bed hole Long-Time Service, wearing and tearing rear vehicle plays bucket and there will be shift phenomenon, thus cause load lifting cylinder skew, a bucket difficulty, and increase lifting pump pressure, easily cause lifting pump damage, load lifting cylinder wearing and tearing leakage of oil, load lifting cylinder bearing damage, also easily cause vehicle rollover in addition.Therefore examine and replace must be carried out in time after there are wearing and tearing, if and unstable wear and above equipment failure also occur by both sides bore decentraction when overhauling, this concentricity precision required when maintenance is described is relatively high, and railway carriage axle both sides spacing is greater than 1.5 meters, be not easy to judge that whether concentricity is up to standard.
Summary of the invention
The purpose of this utility model is to provide a kind of large-scale production truck body stationary axle bore positioning work piece, improve railway carriage axle bed hole repair quality, extend bore life cycle, reduce the rate of fault of lifting pump, load lifting cylinder, load lifting cylinder bearing, improve equipment availability efficiency, stop vehicle rollover and the security incident that causes.
The purpose of this utility model is realized by following technical proposals:
The utility model large-scale production truck body stationary axle bore positioning work piece, it is characterized in that by axis, be located at the middle spacer sleeve in the middle part of this axis, symmetry is located at one group of adjustment packing ring of spacer sleeve both sides in this, positioning spacer, back-up ring and nut formed, described axis is by intermediate light shaft part, the location optical axis section that intermediate light shaft part two ends are connected therewith respectively formed with the section of being threaded that location optical axis section is connected therewith respectively, described middle spacer sleeve and described intermediate light shaft part are that Spielpassung is connected, one group of described adjustment packing ring abuts against the end of described middle spacer sleeve, described positioning spacer and back-up ring are enclosed within described axis successively, described nut is threaded with the section of being threaded of described axis.
Described one group of adjustment packing ring is made up of packing ring I, packing ring II and packing ring III, and described packing ring I thickness size is 1mm, and described packing ring II thickness size is 2mm, and described packing ring III thickness size is 3mm.
Described packing ring I, packing ring II and packing ring III structural type are rounded washers and are provided with U-shaped socket.
The utility model has the advantages that:
1) enforcement of the present utility model can ensure the concentricity of large-scale production truck body stationary axle bore, avoids the error judging generation by artificial naked eyes, improves overhaul efficiency, extend the working life of its associated components;
2) the utility model makes simple, easy to use, and dismounting easily, requires low to the technical merit of operator, reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of the utility model Fig. 1.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, the utility model large-scale production truck body stationary axle bore positioning work piece, it is characterized in that by axis 1, be located at the middle spacer sleeve 7 in the middle part of this axis 1, symmetry is located at one group of adjustment packing ring 6 of spacer sleeve both sides in this, positioning spacer 5, back-up ring 3 and nut 2 formed, described axis 1 is by intermediate light shaft part, the location optical axis section that intermediate light shaft part two ends are connected therewith respectively formed with the section of being threaded that location optical axis section is connected therewith respectively, described middle spacer sleeve 7 and described intermediate light shaft part are that Spielpassung is connected, one group of described adjustment packing ring abuts against the end of described middle spacer sleeve, described positioning spacer and back-up ring are enclosed within described axis successively, described nut is threaded with the section of being threaded of described axis.Large-scale production truck body is fixed axle bed 4 and is made up of two concentric hole bearings, and the center, hole of these two concentric hole bearings is same center line, and namely railway carriage stationary axle is a large-scale long shaft.The installation form of railway carriage stationary axle is simulated in the installation of axis.All parts of number in the figure display axis one side structure, because opposite side parts are identical with it and be symmetrical arranged, therefore repeat no more.
Described one group of adjustment packing ring 6 is made up of packing ring I, packing ring II and packing ring III, and described packing ring I thickness size is 1mm, and described packing ring II thickness size is 2mm, and described packing ring III thickness size is 3mm.Above-mentioned packing ring adopts one or several when using as required.
Described packing ring I, packing ring II and packing ring III structural type are rounded washers and are provided with U-shaped socket.U-shaped socket during equipment adjustment on packing ring inserts on the intermediate light shaft part of axis 1, and it is all convenient to dismantle.
Using method of the present utility model
1) first middle spacer sleeve 7, positioning spacer 5 are arranged on large-scale production truck body and fix on axle bed 4, and middle spacer sleeve 7, positioning spacer 5 center, hole consistent with the center of large-scale production truck body stationary axle bore;
2) in being inserted successively by axis, spacer sleeve 7, positioning spacer 5 and large-scale production truck body are fixed in the hole of axle bed 4;
3) adjust with one group of adjustment packing ring 6 position that large-scale production truck body fixes axle bed 4, make it meet the installation code of railway carriage stationary axle, then use fastening nuts;
4) the complete large-scale production truck body of assembling is fixed axle bed and the utility model positioning work piece and together drop on correct position in vehicle stand, can repair welding operation;
5), after maintenance to be welded completes, removal axis, completes service work.
