Embodiment Construction

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0028] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention, which belongs to the technical field of vehicle quality detecting, provides a bogie sub-frame detecting tool and a method thereof. The detecting tool comprises a supporting bottom plateprovided with two supporting units I and two supporting units II. The detection method includes: four adapters are arranged on four supporting platforms correspondingly in a sub frame; a support unitIII is supported at the middle part for supporting a sub-frame U-shaped end. Whether the four adapters match the four supporting platforms completely is determined to determine whether the sub-frameforming product is qualified. The supporting units I are fixed on the support bottom plate; an adjustment mechanism for adjusting the distance and angles between the two supporting units I and the twosupporting units II is arranged between the two supporting units II and the support bottom plate so as to simulate the actual state of the sub-frame unit during the bogie forming and application processes. The production quality of the sub-frame unit is guaranteed; a problem that the basic measurement method can not measure the related data is solved; a problem that the product is disqualified because of error accumulation of the traditional measurement method is solved; and the work efficiency and economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle quality inspection, and more specifically relates to a bogie sub-frame inspection tool and method. Background technique [0002] The sub-frame used in the bogie is composed of plate welded structure. During the manufacturing process, the structure is relatively complicated and the amount of welding is large, resulting in large deformation of the sub-frame after manufacturing and processing. The welding deformation caused by this reason may appear partly The quality of frame products is unqualified or cannot meet the requirements of bogie completion and assembly. The structure of the sub-frame bogie is relatively complex, and the completion and assembly process is difficult and requires more man-hours; if the quality of the selected sub-frame cannot be guaranteed, there will be two or more reworks, which not only reduces the cost of the bogie. Completion efficiency, waste of man-hours, and the pas...
