Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing, specifically a feeding device for mechanical processing of high-speed train mechanical power assist equipment. Background Technology

[0002] A wheelset generally consists of an axle and wheels. High-speed train wheelsets are further divided into powered wheelsets and unpowered wheelsets. Powered wheelsets usually contain a gearbox, which is part of the drive unit, and due to the increased operating speed, they use disc brakes as the basic braking system.

[0003] Wheelsets, commonly known as tires, differ from car tires. They are made of heat-treated cast steel, giving them extremely high hardness. However, even these hardened wheelsets will gradually wear down and deform under prolonged friction. During operation, rail vehicles are subject to various factors that can cause tread damage such as abrasions and peeling, and even lead to individual wheels becoming out of round.

[0004] As the power support equipment for high-speed trains, wheelsets are often moved and loaded manually during processing. This method is labor-intensive, involves complex procedures, and has low handling efficiency.

[0005] In summary, this utility model provides a feeding device for machining of mechanical power assist equipment for high-speed trains, in order to solve the above-mentioned problems. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a feeding device for machining of mechanical power-assisted equipment for high-speed trains, thereby solving the problems of high labor intensity and complex operation processes in existing technologies that mostly rely on manual labor to move and feed wheelsets.

[0007] A loading device for machining in a high-speed train's mechanical power-assisted equipment includes a loading carriage. A cavity groove is formed on the surface of the loading carriage, and a tilting shaft is installed within the cavity groove. Two symmetrical tilting frames are fitted onto the surface of the tilting shaft, and the tilting frames are respectively located at both ends of the tilting shaft. The two tilting frames are connected by a double-axis screw. A drive shaft is located at the bottom of the tilting shaft, and drive gears are fitted onto both ends of the drive shaft. A drive gear is installed on one end of each tilting frame near the drive shaft, and the drive gear contacts the drive gear. A wheelset support is rotatably connected to the end of each tilting frame away from the drive gear. The wheelset support is connected to the tilting frame via a counterweight shaft, and a counterweight block is fixedly connected to the surface of the counterweight shaft. A servo motor is installed at one end of the loading carriage, and one end of the drive shaft movably passes through the cavity groove and is drively connected to the output shaft of the servo motor.

[0008] Furthermore, both ends of the dual-axis screw movably pass through the flipping frame, and the dual-axis screw and the flipping frame are connected by threads.

[0009] Furthermore, the driving gear includes a gear block and a limiting ring. The gear block and the limiting ring are respectively installed at the end of the tilting frame away from the wheelset support frame. Limiting rings are respectively provided on both sides of the gear block. The driving gear meshes with the gear block, and the limiting rings contact the outer walls on both sides of the driving gear.

[0010] Furthermore, a spline is mounted on the surface of the drive shaft, and the spline is slidably connected to the drive gear.

[0011] Furthermore, the two ends of the counterweight shaft movably pass through the tilting frame and are connected to the wheel set support frame. The surface of the wheel set support frame has an arc-shaped structure, and the counterweight block is positioned above the dual-axis screw.

[0012] Furthermore, the counterweight is disposed on the surface of the counterweight shaft, and limit grooves are respectively opened at both ends of the counterweight shaft. The wheel set support is slidably connected in the limit grooves by limit sliders, and the limit grooves are arranged along the axial direction of the counterweight shaft.

[0013] Furthermore, the end of the tilting frame near the drive gear has an arc-shaped structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model provides a wheelset support frame to support the wheelset. By setting a flipping frame and a drive gear, the wheelset support frame can be flipped to enable loading and unloading of wheelsets in the workshop. By adjusting the flipping direction of the wheelset support frame, the position of the wheelset can be adjusted, reducing the workload of manual loading and unloading.

[0016] 2. This utility model, by setting a dual-axis screw, can adjust the spacing of the tilting frame by driving the dual-axis screw, which is suitable for the processing and feeding of various models of wheelsets. By setting a counterweight shaft and counterweight blocks, the gravity of the counterweight shaft can be made downward, always keeping the direction of the wheelset support frame. With the gravity downward and the opening of the wheelset support frame facing upward, the safety of feeding the wheelsets is guaranteed. Attached Figure Description

[0024] like Figure 1-4 As shown, this utility model provides a feeding device for machining of mechanical power assist equipment for high-speed trains, including a feeding carriage 1. The surface of the feeding carriage 1 is provided with a cavity groove 2. A tilting shaft 4 is provided in the cavity groove 2. Two mutually symmetrical tilting frames 5 are sleeved on the surface of the tilting shaft 4. The tilting frames 5 are respectively located at both ends of the tilting shaft 4. The two tilting frames 5 are connected by a double-shaft screw 9. A drive shaft 3 is provided at the bottom of the tilting shaft 4. Drive gears 10 are respectively sleeved at both ends of the drive shaft 3. A drive gear 8 is installed on the end of the tilting frame 5 near the drive shaft 3. The drive gear 8 is in contact with the drive gear 10. A wheel set support 6 is rotatably connected to the end of the tilting frame 5 away from the drive gear 8. The wheel set support 6 is connected to the tilting frame 5 through a counterweight shaft 11. A counterweight block 7 is fixedly connected to the surface of the counterweight shaft 11. A servo motor is installed at one end of the feeding carriage 1. One end of the drive shaft 3 movably passes through the cavity groove 2 and is connected to the output shaft of the servo motor.

[0025] In one embodiment of this utility model, the two ends of the dual-axis screw 9 respectively movably pass through the flipping frame 5, and the dual-axis screw 9 and the flipping frame 5 are connected by threads.

[0026] As one embodiment of this utility model, the driving gear 8 includes a gear block 801 and a limiting ring 802. The gear block 801 and the limiting ring 802 are respectively installed at one end of the flipping frame 5 away from the wheel support frame 6. Limiting rings 802 are respectively provided on both sides of the gear block 801. The driving gear 10 meshes with the gear block 801, and the limiting rings 802 are in contact with the outer walls on both sides of the driving gear 10.

[0027] In one embodiment of this utility model, a spline 12 is mounted on the surface of the drive shaft 3, and the spline 12 is slidably connected to the drive gear 10.

[0028] In one embodiment of this utility model, the two ends of the counterweight shaft 11 movably pass through the tilting frame 5 and are connected to the wheel set support frame 6. The surface of the wheel set support frame 6 is an arc-shaped structure, and the counterweight block 7 is set above the double-axis screw 9.

[0029] As one embodiment of this utility model, the counterweight 7 is disposed on the surface of the counterweight shaft 11, and the two ends of the counterweight shaft 11 are respectively provided with limiting grooves 13.

[0030] As one embodiment of this utility model, the end of the flipping frame 5 near the drive gear 8 has an arc-shaped structure.

[0031] Specific working principle:

[0032] When loading and unloading materials, the servo motor is started, which drives the drive shaft 3 to rotate. When the drive shaft 3 rotates, the drive gear 10 drives the drive gear 8 to rotate along the tilting shaft 4, and then the tilting frame 5 tilts to one side of the loading cart 1. When the tilting frame 5 tilts, the upper wheel support frame 6, under the gravity of the counterweight shaft 11, always faces upward, placing the wheelset on the two wheel support frames 6. Then the drive shaft 3 is rotated in the opposite direction again, and the drive shaft 3 drives the tilting frame 5 to return to its original position. The loading cart 1 moves the wheelset to the loading position, and the height of the wheelset is adjusted by the servo motor to realize loading.

[0033] When adjusting the wheel spacing, the two tilting frames 5 can be moved closer or further apart by rotating one end of the dual-axis screw 9, thereby adjusting the spacing.

[0034] When adjusting the pitch, the drive gear 10 and drive gear 8 slide on the surface of the spline 12, while the wheelset support 6 slides on the surface of the limiting groove.
