Description

Technical Field

[0001] This utility model relates to equipment machinery for rail transit, specifically to a wheelset pre-assembly machine. Background Technology

[0002] Before the train wheelsets are put into the press machine for fixed installation, a pair of wheels must be pre-installed by fitting them onto the axle. Then, they are sent into the press machine by a transfer tool. It is understood that there are various types of existing pre-installation machines, but some pursue a high degree of mechanization and automation, which makes their structure more complex, cost more, and difficult to manufacture. Moreover, existing pre-installation machines cannot pre-install gears, which cannot meet customer requirements. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a wheelset pre-assembly machine with a simple structure that can pre-assemble wheelsets and gears, saving time and effort and meeting customer requirements.

[0004] To achieve the above objectives, the technical solution of this utility model is a wheelset pre-assembly machine, comprising two sets of pre-assembly heads, characterized in that: the two sets of pre-assembly heads are symmetrically arranged facing each other, and each pre-assembly head includes a base, a support, a lifting assembly, and a wheel clamping assembly; the support is located on the base, the lifting assembly is located in front of the working face of the support, and the wheel clamping assembly is a pair symmetrically arranged on both sides of the support. The base is a cuboid; The side of the support is trapezoidal; The lifting assembly has a U-shaped bracket, and a drive assembly for raising and lowering it is connected to the rear of the U-shaped bracket; The clamping wheel assembly is provided with a clamping swing arm, and a rotary cylinder is connected to the clamping swing arm. The rotary cylinder is located in the mounting base. A guide assembly is provided between the support and the bottom, and the guide assembly is connected to a power assembly; A guide assembly is provided between the support and the U-shaped bracket.

[0005] The drive component is a servo motor connected to the elevator.

[0006] The guiding component is a guide rail and guide groove pair.

[0007] The power component is an electric motor.

[0008] The U-shaped bracket is equipped with nylon blocks.

[0009] The advantages of this invention are that it enables pre-assembly of wheelsets and gears, saving time and effort and meeting customer requirements. It also features a simple structure, low cost, and ease of manufacturing. Attached Figure Description

[0016] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] like Figures 1 to 9 As shown, this utility model discloses a wheelset pre-installation machine 100, including two sets of pre-installation heads 101. The two sets of pre-installation heads are symmetrically arranged facing each other and fixed to the ground plane. The distance between them is greater than that between the wheelsets. Each pre-installation head includes a base 1, a support 2, a lifting assembly 3, and a wheel clamping assembly 4. The lifting assembly is located in front of the working face of the support, and the wheel clamping assembly is a pair symmetrically arranged on both sides of the support. The base is a cuboid; The side of the support is trapezoidal; The lifting assembly consists of three parts, each with a U-shaped bracket 31 and a drive assembly 32 connected to the rear of the U-shaped bracket to raise and lower it. The clamping wheel assembly 4 is provided with a clamping swing arm 41, and a rotary cylinder 42 is connected to the clamping swing arm. The rotary cylinder is located in the mounting base 43. A guide assembly 5 is provided between the support and the bottom, and a power assembly 6 is connected to the guide assembly; A guide assembly 5 is provided between the support and the U-shaped bracket.

[0018] The drive component is a servo motor 322 connected to the elevator 321.

[0019] The guiding component is the guide rail and guide groove pair 5.

[0020] The power component is motor 6.

[0021] The U-shaped bracket has nylon blocks 311 on its contact surface to prevent rigid collisions from damaging the wheels and gears.

[0022] The pre-assembly process for this machine is as follows; the pre-assembly process for the wheels and gears is the same: like Figure 4 As shown, the axle journal transition sleeve is manually fitted onto the journals at both ends, and then the axle is manually hoisted onto the trolley support arm. The trolley support arm lifts the axle to a position concentric with the machine and the pressing center. like Figure 5 As shown, the pre-installed machine lifting assembly is raised to a position concentric with the axle, and the axle is manually lifted onto the U-shaped bracket; like Figure 6 As shown, the rotary clamping cylinder is activated, and the cylinder clamping arm clamps the wheel to prevent it from tipping over. like Figure 7 As shown, the pre-installation machine's two end supports move the wheels forward, fitting the wheels onto the axles until they are pressed into place. like Figure 8 As shown, after pre-installation, the rotary clamping cylinder is released, the lifting assembly descends to a certain position, and the pre-installation machine returns to its initial state.

[0023] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
