[0007] A first linear drive assembly is provided between the bracket and the base frame;

[0008] A second linear drive assembly is provided between the roller support device and the base plate of the bracket.

[0009] Both the first and second linear drive components are hydraulic cylinders equipped with guide rails and guide grooves for driving.

[0010] The hydraulic cylinder device has a support connected to the base frame, a hydraulic cylinder seat on the support, and an hydraulic cylinder axially installed inside the hydraulic cylinder seat, located below the pre-installed hydraulic cylinder, with its piston rod end connected to a bracket.

[0011] The front panel of the bracket has four pads symmetrically arranged on the top and bottom.

[0012] The roller support device consists of two mountain-shaped clamping plates connected to a horizontal base. The mountain-shaped clamping plates have a roller support groove in the middle, and a V-shaped support block is provided in the middle of the roller support groove.

[0031] 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.

[0032] like Figures 1 to 10As shown, this utility model discloses a wheelset pre-assembly machine 100, which is composed of two sets of pre-assembly devices 101 arranged symmetrically on an axis; the two sets of pre-assembly devices are installed on a mountain-shaped foundation;

[0033] The pre-assembly device 101 comprises a base frame 1, a pre-assembly assembly 2, a hydraulic cylinder device 3, and a support roller device 4; the pre-assembly assembly is mounted on the base frame, and the hydraulic cylinder device is mounted behind the pre-assembly assembly.

[0034] The pre-installed component 2 has a bracket 21, a clamping wheel device 22 on the front plate of the bracket, a supporting wheel device 23 below the clamping wheel device, and a pre-installed hydraulic cylinder 24 axially located in the middle of the bracket.

[0035] A first linear drive assembly 5 is provided between the bracket and the base frame;

[0036] A second linear drive assembly 6 is provided between the roller support device and the base plate of the bracket.

[0037] Both the first and second linear drive components are hydraulic cylinders equipped with guide rails and guide grooves for driving.

[0038] The hydraulic cylinder device 3 has a support 31 connected to the base frame, a hydraulic cylinder seat 32 on the support, and an axial hydraulic cylinder 33 axially arranged inside the hydraulic cylinder seat, located below the pre-assembled hydraulic cylinder, with its piston rod end connected to a bracket; this hydraulic cylinder directly pushes the pre-assembled assembly forward on the pre-assembled wheelset.

[0039] The front panel of the bracket has four symmetrical pads 7 arranged on the top and bottom to cushion the wheels and prevent them from tilting when clamping them.

[0040] The roller support device 4 consists of two mountain-shaped clamping plates 41 connected to a horizontal seat 42. A roller support groove 43 is provided in the middle of the mountain-shaped clamping plates, and a V-shaped support block 44 is provided in the middle of the roller support groove. An inclined plate 45 and a stop block 46 are provided at both ends of the V-shaped support block.

[0041] The aforementioned clamping wheel device has been described and disclosed in previous applications of the applicant. For example... Figure 2 As shown, the front panel of the bracket is equipped with a clamping wheel cylinder and upper and lower clamping claw mounting plates. Two clamping claws are symmetrically arranged on the clamping claw mounting plates. On the upright frame, there are two sprockets, one on the upper sprocket and one on the lower sprocket. The chain on the upper sprocket is connected to the upper clamping claw mounting plate at one end, passes around the sprocket, and connects to the lower clamping claw mounting plate at the other end. The chain on the lower sprocket is connected to the lower clamping claw mounting plate at one end, passes around the sprocket, and connects to the upper clamping claw mounting plate at the other end. A vertical guide component is provided between the clamping claw mounting plate and the upright bracket. The clamping wheel cylinder is connected to and drives the upper clamping claw mounting plate.

[0042] like Figure 4-10 As shown, the pre-assembly process of this utility model is as follows:

[0043] Figure 4The axle-supporting trolley delivers the axle to the predetermined position, while the wheel rolls into the machine's wheel support device and pauses.

[0044] Figure 5 The clamping wheel device in the left and right pre-installed devices is activated to clamp the wheel and bring it to the predetermined center position;

[0045] Figure 6 Once the clamping wheel is engaged, the support wheel device retracts.

[0046] Figure 7 The left and right hydraulic cylinder devices are activated, pushing the pre-installation device to the predetermined position, and the axle support trolley lifts the axle to the pre-installation height;

[0047] Figure 8 When the pre-installed hydraulic cylinders on the left and right are started, the piston rod extends and presses against the axle, and the tip enters the axle hole for positioning, so that the axle and the wheel are concentric.

[0048] Figure 9 The left and right hydraulic cylinders drive the pre-assembly device to perform pre-assembly operations;

[0049] Figure 10 Once pre-assembly is complete, the axle support trolley sends the pre-assembled wheelset to the next process, and the left and right pre-assembly cylinders and devices are reset.

[0050] The above description is merely one embodiment of this utility model and is not intended to limit the utility model.
