Abstract
The utility model discloses a bushing mounting tool, which comprises a guide screw, a pair of nuts, a pair of plane thrust bearings and a pair of guide sleeves, wherein the pair of nuts are arranged on the guide screw; the middle section of the guide screw is a polished rod section, and two ends of the guide screw are processed into threaded sections; the two guide sleeves are sleeved on the polished rod section; the two nuts are in threaded connection with the threaded section; the two thrust bearings are sleeved on the screw rod between the guide sleeve and the nut, so that the operation difficulty and the working strength of workers are reduced, and the production efficiency and the product quality are improved.
Description
Technical Field
The utility model relates to the technical field of airplane assembly, in particular to airplane bushing assembly.
Background
Many connecting holes on the airplane component need to be provided with a lining to improve the fatigue resistance and the wear resistance of the connecting holes, and the lining is pressed into the connecting holes in an artificial spiral static pressure mode after being placed into liquid nitrogen for cold shrinkage in a conventional lining installation method in an assembly stage. The method for installing the bushing is easy to cause the bushing and the bottom hole to be not coaxial, the contact surface of the installation tool and the part is seriously abraded due to large force, the installation tool needs to be carried out twice when the bushing is pressed on the two sides, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides a bushing mounting tool, which solves the problems of low coaxiality and serious wear of a contact surface in the mounting process of the conventional bushing.
The purpose of the utility model is realized as follows: a bush mounting tool includes a lead screw, a pair of nuts, a pair of flat thrust bearings, and a pair of guide sleeves;
the middle section of the guide screw rod is a polished rod section, and two ends of the guide screw rod are processed into threaded sections;
the two guide sleeves are sleeved on the polished rod section;
two nuts are in threaded connection with the threaded section;
two thrust bearings are sleeved on the screw rod between the guide sleeve and the nut.
When the utility model is used:
firstly, inserting the guide sleeves into the through holes of the bushings to be installed, then penetrating the two through holes and the two guide sleeves by using the guide screws, sequentially sleeving the bushings, the thrust bearings and the nuts from the two end sleeves of the guide screws after the guide screws are completed, rotating the nuts, pushing the bushings from the two ends of the parts to be inserted into the through holes through the thrust bearings, and completing the assembly.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model adopts the design of the guide screw, ensures the coaxiality of the bushing during the assembly by matching with the guide sleeve, and further ensures the coaxiality of the bushing during the insertion process by matching the nut with the thrust bearing, thereby solving the problem of serious abrasion of the contact surface during the installation of the existing bushing, reducing the operation difficulty and the working strength of workers, and improving the production efficiency and the product quality.
As an improvement of the utility model, a cushion block is sleeved between the two cushion blocks at the middle section of the guide screw rod. The effect of supporting is played through increasing the cushion, influences the axiality problem in avoiding the bush assembling process.
In order to enable the guide sleeve to be more convenient to mount and dismount, a flange edge is processed at one end of the guide sleeve.
