[0016] The following describes the embodiments with reference to the accompanying drawings to further illustrate the specific implementation of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, etc.
[0017] like Figure 1 As shown, the skirt coaxiality detection device includes an aluminum rectangular tube 1, a hook seat 3 and a latch seat 4. There are two hook seats 3, both of which are set on one side of the aluminum rectangular tube 1. There are two latch seats 4, both of which are set on the top surface of the aluminum rectangular tube 1. A latch 5 is set on the latch seat 4. The two hook seats 3 are coaxially arranged, and the two latch seats 4 are coaxially arranged. The hook seat 3 and the latch seat 4 are arranged at the two ends of the aluminum rectangular tube 1. A positioning pin 6 is set on the outer surface of the hook seat 3, and a handle 10 is set on the bottom surface of the aluminum rectangular tube 1. The hook seat 3, the latch seat 4 and the fixing plate 2 are fastened by a hexagon socket head screw 7. The hexagon socket head screw 7 is screwed into the hole of the aluminum rectangular tube 4 to set a flat washer 8 and a spring washer 9, both of which act as gaskets. The hook seat 3 is fixed to the side of the aluminum rectangular tube 1 through the fixing plate 2.
[0018] like Figure 2 As shown, when inspecting the coaxiality of the train skirt hook, the inspector holds the tool handle 10 and inserts the pin 5 on the skirt coaxiality tool parallel to the skirt hook to be inspected from one side, and observes whether there is interference during the process. At the same time, a feeler gauge is used to detect the gap and fit rate between the pin and the skirt hook, and the values are recorded. After use, the tool is returned to its place for next use.
[0019] like Figure 3 As shown, when inspecting the coaxiality of the vehicle body hanging shaft, the inspector holds the handle of the tool and hangs the hooks on the hook seats 3 at both ends of the skirt coaxiality tool parallel to the vehicle body hanging shaft, and observes whether there is interference during the process. At the same time, use a feeler gauge to detect the gap and fit rate between the hook and the vehicle body hanging shaft, and record the values. After use, return the tool to its place for next use.
[0020] This skirt coaxiality detection device is simple and convenient to operate, which improves the qualified rate of the operation; it also meets the two detection requirements of skirt hooks and body hanging shafts, improving work efficiency; the main body of the tooling adopts an aluminum structure, which is light to use and improves the safety of the operation.
[0021] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
