Description

Technical Field

[0001] The invention relates to the technical field of auxiliary tooling for rail vehicle component assembly, and in particular to a device for measuring the installation angle of rail vehicle components and pipelines. Background Art

[0002] In the production of EMU projects, in order to effectively avoid interference problems between components during assembly, especially during the process of tightening pipelines, due to the differences in the shapes of pipeline connectors and the characteristics of pipeline serial assembly, it is easy for the pipe connectors to rotate when the pipelines are gradually tightened in multiple dimensions. Therefore, two people are often required to use a level ruler and an angle ruler to repeatedly calibrate and adjust the angles to complete the positioning and tightening of the component position size and installation angle. In addition, since the pipe connectors are hexahedral structures and some pipelines are installed in limited positions and sizes, it is often impossible to accurately build a reference surface for measurement after tightening and use existing measuring tools to accurately measure the inclination angle of the pipeline;

[0003] In addition, during the daily pipeline positioning and installation process, the pipeline is often too close to the adjacent components on the vehicle, resulting in the inability to install the experimental catheter during the debugging process, and even contact and interference with other components, resulting in stress. As a result, relative movement between the pipeline and components often occurs during the operation of the EMU, leading to pipeline leakage problems.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a device for measuring the installation angles of rail vehicle components and pipelines. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a device for measuring the installation angles of rail vehicle components and pipelines, which can realize the convenient construction of the measuring reference surface, the rapid measurement of the angles and the reading of the numerical values, so as to facilitate the construction personnel to quickly and conveniently complete the pipeline angle measurement and the fastening and positioning, and effectively prevent the pipeline interference and leakage that affect the driving safety.

[0014] Furthermore, the leveling display system includes scale lines formed on both sides of the angle disk, and a fixed slot formed on the side of the angle disk opposite to the shaft slot structure, and the fixed slot is fixedly connected to a horizontal bubble.

[0015] Furthermore, the reading structure is the brake angle disc symmetrically arranged on both sides of the angle disc, and a pointer corresponding to the scale on the angle disc is formed on the side of the brake angle disc.

[0016] Furthermore, the counterweight structure includes a counterweight installation hole opened on the brake angle disc and a counterweight, and the counterweight is embedded in the counterweight installation hole by interference fit.

[0017] Furthermore, the dynamic measurement structure relies on the weight of the counterweight block to drive the pointer on the brake angle disk to generate an angular position difference on the angle disk.

[0018] Furthermore, the limit assembly system includes a shaft rod, and connecting sections with a triangular cross-section are arranged at both ends of the shaft rod. The connecting section transitionally fits with the triangular mounting hole on the brake angle disc, and the boss formed at the end of the connecting section by the shaft rod blocks the displacement of the brake angle disc, so that the brake angle disc rotates with the shaft rod, and the shaft rod is rotatably connected to the angle disc through a ball bearing.

[0019] Furthermore, both ends of the shaft are processed with internal threads for threaded connection with washer screws, and the brake angle disc is connected to the angle disc through the washer screws.

[0050] Step 4: Driven by the weight of the counterweight 12, the pointers 8 on the brake angle discs 2 on both sides produce an angular position difference with the angle disc 4. The operator can always observe the angle of the parts or pipes to be fastened during the tightening process, and the real-time display of the measured angle is realized.
