Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for assembling rail vehicle wheel components, and in particular to a rail passenger vehicle wheel flange support assembly device. Background Technology

[0002] like Figure 1 As shown, the rail passenger car wheel flange support is composed of base plate 1-1, upright plate 1-2, stiffening plate A1-3, stiffening plate B1-4, and stiffening plate C1-5. Since the corresponding positional relationship of each component is difficult to grasp, it brings difficulties to the assembly process.

[0003] The current assembly method involves the operator drawing multiple auxiliary lines on the upper surface of the base plate 1-1 according to the dimensions specified in the design drawings before assembly. Simultaneously, the angle between the upright plate 1-2 and the base plate 1-1 is adjusted. After assembling the upright plate 1-2, auxiliary lines are drawn again according to the dimensions in the drawings to assemble the corresponding stiffening plates. After assembly, the positions and angles of each component are re-measured to confirm that the dimensions in each direction meet the drawing requirements. Because the assembly process requires zero tolerance for error, manual assembly in batch production often leads to errors in the operator's measuring and marking, resulting in a failure to guarantee the final assembly accuracy. This results in an extremely high rework rate, increasing production costs, increasing the operator's workload, and causing low production efficiency, severely restricting production.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A base platform for supporting the wheel flange bracket, the upper part of which is provided with a first positioning mechanism for mounting the wheel flange bracket base plate; and

[0008] The second positioning mechanism is fixed to the base platform and is used to provide a positioning surface that contacts the side wall of the stiffener A.

[0009] The third positioning mechanism, fixed to the base platform, provides positioning surfaces that contact the surface of the upright plate and the side wall, respectively; it also includes...

[0010] A fourth positioning mechanism, which can be separated from the base platform, abuts against the third positioning mechanism and is used to provide a positioning surface and support stiffeners B and C.

[0011] Furthermore, the first positioning mechanism consists of a first positioning post, a second positioning post, a third positioning post, and a fastening mechanism that are fixedly connected at intervals to the base platform.

[0012] Furthermore, the fastening mechanism has a top rod in its helical drive for fixing the base plate.

[0015] Furthermore, the fourth positioning mechanism is an L-shaped support frame, with a first baffle and a second baffle fixedly connected at intervals on one side of the support frame, and stiffeners B and C can abut against the first baffle and the second baffle respectively.

[0016] The rail passenger car wheel flange support assembly device provided by this utility model has the following advantages in the above technical solution:
