Rapid detection device for parallelism of traction beam assembly and detection method thereof

Abstract

The invention discloses a rapid detection device for the parallelism of a traction beam assembly and a detection method thereof, which relate to the technical field of assembly of traction beam assemblies of bogies of motor train units. The detection device comprises a wedge-shaped centering detection plate, a positioning detection plate, a base platform, a nylon conical sleeve, a backstop, an air cylinder and an air cylinder supporting seat. The middle vertical plane of the wedge-shaped centering detection plate is used for replacing the virtual central plane A of the positioning groove, the positioning detection plate is used for replacing the reference plane, rapid detection of the parallelism between the virtual central plane A of the positioning groove and the reference plane is ingeniously achieved, and convenience is high. The parallelism of two dimensions of transverse measurement and longitudinal measurement is quantitatively measured, the detection precision is high, and the reliability is high; the device is simple and practical in structure and convenient to operate, the material transportation cost and the equipment detection cost are reduced, the measurement process is greatly simplified, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of assembling the traction beam assembly of the bogie of an EMU, in particular to a device for quickly detecting the parallelism of the traction beam assembly and a detection method thereof. Background technique [0002] Such as Figure 1 to Figure 4 As shown, the traction beam assembly 8 of the bogie of the EMU with a speed of 250 kilometers per hour and 350 kilometers per hour is formed by coaxially pressing the conical center pin sleeve 8-1 into the traction beam 8-2, and the four traction beams on the traction beam 8-2 The eight end faces of the tie rod assembly hole 8-2-1 are all parallel, and this end face is the datum plane for parallelism detection. The virtual central plane A of the positioning groove 8-1-1, after the press-fitting is completed, it is necessary to ensure that the virtual central plane A of the positioning groove 8-1-1 and the reference plane meet the shape and position tolerance req...

Problems solved by technology

[0005] In order to solve the problem of high inspection cost of 3D detection equipment in the prior art, and the problem of assembly deviation caused by fixture wear and tapered center pin sleeve rotation phenomenon, it is not convenient to quickly detect and find in daily work, which will lead to tapered center pin Difficulty in positioning and interference of sleeves in subsequent assembly can not be found until the later stage of assembly, which affects product quality and disassembly efficiency. The present invention provides a fast detection device and detection method for parallelism of traction beam components.
