[0025] Embodiment 1

[0026] Since the traction motor is heavy, it needs to be lifted by a crown block for installation. However, the traction motor is prone to shaking during the installation process, which causes the bolts to be often rotated and deflected during the installation, resulting in damage to the bolt holes of the traction motor. Based on this, the present embodiment provides a wheel set component assembly workbench for supporting the traction motor and adjusting the height of the gear box during the installation of the traction motor of the rail transit vehicle, so that the two are aligned and the bolts are rotated into the motor to fasten it, overcoming the above problems.

[0027] The wheel set component assembly workbench of the present embodiment is provided with a wheel set support position, a motor support position and a boom connection support position 7. Since the wheel set has two wheels, the wheel set support position is provided with two, a total of four support positions, to realize stable support of the components to be assembled.

[0028] Specifically, as shown in Figure 1 and Figure 2 , the wheel set component assembly workbench comprises a workbench main body 1. The workbench main body 1 serves as a bearing platform and can meet the bearing requirements. Its structure form can be set according to actual requirements. In the present embodiment, the workbench main body 1 is composed of one cross beam 1-1 and two longitudinal beams 1-2. The cross beam 1-1 and the longitudinal beams 1-2 connected at both ends thereof form a U-shaped structure, and the opening end formed thereby facilitates the installation of the gear box.

[0029] The wheel set support position is composed of support positioning arms 2. The support positioning arms 2 are fixed to the upper side of the cross beam 1-1 of the workbench main body 1. There is a certain interval between the two support positioning arms 2, which can accommodate the components (gear box, traction motor) between the wheel sets. The top surface of the support positioning arm 2 is a horizontal surface, which forms support for the wheel set. In the present embodiment, the support positioning arm 2 comprises a top plate and a support plate. The top plate is fixed to the cross beam 1-1 through the support plate. The top plate is a rectangular plate, and its upper surface is the support surface.

[0030] It can be understood that in other embodiments, the support positioning arm 2 can also adopt other structures as long as it has a support surface for the wheel set.

[0031] The motor support position is formed by a support base 3, which is connected to one side of the cross beam 1-1 and located in the U-shaped opening formed by the workbench main body 1; the top surface of the support base 3 is a contact surface with the traction motor, which is adapted to the size of the traction motor to achieve stable support of the traction motor. In this embodiment, the support base 3 is composed of an L-shaped plate and triangular rib plates fixed on both sides of the L-shaped plate, which can realize a stable support structure. Of course, in other embodiments, the structure of the support base 3 can be adjusted adaptively.

The boom connecting support position is composed of a support beam 4 and a lifting support assembly, one end of the support beam 4 is connected to the cross beam 1-1 of the workbench main body 1, and the other end is installed with the lifting support assembly. The support beam 4 of this embodiment is a cantilever beam, and the lifting support assembly is located at the free end of the support beam 4, and the boom connecting support position 7 is formed at the free end of the support beam 4.

[0033] In this embodiment, the lifting support assembly includes an adjusting rod 6 and a support pedestal 5, the adjusting rod 6 is arranged in the vertical direction, one end of the adjusting rod 6 is threadedly connected with the support beam 4, and the support pedestal 5 is installed at a certain height position of the adjusting rod 6; the height of the support pedestal 5 can be adjusted by rotating the adjusting rod 6, so as to adjust the position of the gear box boom connecting part, so that the gear box mounting hole can be aligned with the traction motor bolt hole; after the position is adjusted, it can be fixed by a nut.

[0034] It can be understood that in other embodiments, the height adjustment mode of the support pedestal 5 can be adjusted to one of the following modes: the support pedestal 5 is threadedly connected with the adjusting rod 6, and the height of the support pedestal 5 is adjusted by rotating the support pedestal 5; the adjusting rod 6 is connected with an electric push rod, a hydraulic cylinder or an air cylinder, etc., to form an automatic height adjustment mode.

[0035] The support pedestal 5 has a table surface for limiting to support the gear box boom connecting part. Specifically, the support pedestal 5 is composed of two parts connected as a whole, wherein the first part is the main part of the support pedestal 5, which is cylindrical; the second part is connected to the bottom of the first part, which is also cylindrical, but the diameter of the second part is larger than that of the first part to form a limiting structure.

[0036] The track wheels 8 are also installed at the bottom of the workbench main body 1, in this embodiment, at least two track wheels 8 are installed at the bottom of each longitudinal beam 1-2, which can realize the transportation of the assembled finished product to the assembly station. The workbench can be transferred by setting a traction device, etc.

[0037] The working principle of this embodiment is as follows:

[0038] When the wheelset is supported by the support positioning arm 2 at the two end support positions, the front end is supported by the lifting support assembly gear box boom connection part, then the traction motor is lifted to the motor support position, slowly put down and fine-tuned to the corresponding position of the gear box mounting hole, then the height of the support pedestal 5 of the lifting support assembly is adjusted, the gear box mounting hole is aligned with the traction motor bolt hole, the bolt is screwed, and the torque is applied.

[0039] The embodiment mainly relates to two aspects of adjustment, one is the fine-tuning after the traction motor is lowered, that is, the traction motor is adjusted on the side of the motor support position towards the position of the gear box mounting hole, the adjustment can be multi-directional fine-tuning, so that the traction motor bolt hole is basically aligned with the gear box mounting hole; the other is the Z-direction adjustment after the above fine-tuning process, that is, the gear box height is adjusted to correspond to the traction motor.

[0040] By the above manner, the embodiment can ensure the assembly quality of the traction motor, avoid the damage of the product thread hole caused by unstable hoisting and installation of the crown block, reduce the influence on the production cycle and cost of the existing vehicle, and further reduce the vehicle production cost.
