Problems solved by technology

[0007] However, in this technical solution, the principle of non-falling wheels is used for repairing. The two supporting wheels and the wheel set intersect to form a centerless repairing method. The poor repairing accuracy of this method cannot meet the operating requirements and experimental requirements of the existing high-speed railway. Only one steering wheel or track wheel can be repaired, and the steering wheel and track wheel cannot be repaired at the same time, so the work efficiency is poor

Embodiment 1

[0064] Such as Figure 3-5 As shown, the axle box bearing comprehensive test bench repair equipment includes: a car body 100, two sets of positioning components 200 arranged at both ends of the car body 100, several groups of bogies 300 arranged in a linear row under the car body 100, and correspondingly arranged on the steering wheel. The track wheel system 400 directly below the frame 300; the track wheel system 400 includes two sets of track wheel assemblies 401 arranged linearly; the track wheel assembly 401 includes two track wheel units 402 arranged symmetrically left and right; the vehicle body Several counterweights 101 are provided on the 100 to adapt to tests under different counterweight conditions;

[0065] It also includes a guide rail assembly 500 arranged between the bogie 300 and the rail wheel system 400 , and multiple sets of turning repair systems 1 correspondingly arranged on one side of the rail wheel assembly 401 and sliding left and right on the rail ass...

Embodiment 2

[0087] Such as Figure 15-20 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between this embodiment two and embodiment one is:

[0088] In this example, if Figure 15-20 As shown, the axial positioning unit 2 includes a mounting seat 21 installed on the supporting seat of the track wheel assembly 401, an adjusting seat 22 mounted on the mounting seat 21 for rotation, and a power part for driving the adjusting seat 22 to rotate 23. The driving part b24 provided at one end of the adjustment seat 22 and the pressure wheel seat 25 which is connected to the output end of the drive part b24 and slidably arranged at the other end of the adjustment seat 22, and the pressure wheel seat 25 is provided with a pressure wheel 26 for rotation ;

Embodiment 3

[0096] The method for simultaneously repairing rail wheels and wheelsets using the axle box bearing comprehensive test bench repair equipment described in the technical solutions of the above-mentioned embodiments 1 to 2 is as follows, including the following steps:

[0097] Step 1, the positioning of the bogie 300, the bogie 300 is transferred to the top of the rail wheel system 400, and the axis of the bogie 300 and the axis of the rail wheel system 400 are placed in the same vertical plane by adjusting the positioning assembly 200, and the track The wheel 403 is in contact with the steering wheel 301;

[0098] Step 2: preload the steering wheel 301 and the track wheel 403, adjust the axial positioning unit 2, and rotate the pressure wheel seat 25 located at one end of the track wheel assembly 401 upwards, make the pressure wheel 26 contact the steering wheel 301, and use the driving part b24 to drive The pressure wheel 26 advances and compresses the edge of the steering whe...

Abstract

The invention provides an axle box bearing comprehensive test bench repair equipment and method thereof, comprising: a car body, two sets of positioning components arranged at both ends of the car body, several groups of bogies linearly arranged under the car body, and correspondingly arranged on the bogies The track wheel system directly below; the track wheel system includes two sets of track wheel assemblies linearly arranged; the track wheel assembly includes two track wheel units symmetrically arranged left and right; The guide rail assembly between the systems and the multiple sets of turning repair systems corresponding to one side of the track wheel assembly and sliding left and right on the guide rail assembly; through the multiple sets of turning repair systems on the guide rail assembly, the steering wheel and track Carry out synchronous turning and repairing of the wheels; use the steering wheel and the track wheel to rotate the turning on their respective rotating shafts to realize centering turning and turning; the turning and turning components are compact in structure and high in machining accuracy.

Description

technical field [0001] The invention relates to the technical field of vehicle maintenance, in particular to an axle box bearing comprehensive test bench repair equipment and a method thereof. Background technique [0002] During the long-term experiment of the test bench, the wheel rim and tread contact surface of the steering wheel and the track wheel wear and tear, resulting in the failure of the surface precision, which affects the test precision and the accuracy of the experimental data. [0003] In the existing technical solution, the vehicle repair is carried out by disassembling the rail wheel and the wheel set, which has disadvantages such as reinstallation after the repair is completed, complicated process path, difficult disassembly, long maintenance time, and high cost. [0004] Such as figure 1 As shown, the bogie 300 includes a steered wheel 301 , a frame 302 , an axle box 303 and a driving part c304 . [0005] Such as figure 2 As shown, the track wheel sys...
