Abstract
Description
Technical Field
[0001] This utility model belongs to the field of train wheel processing technology, and more specifically, it relates to a processing device for oblique oil holes in train wheels. Background Technology
[0002] The oil injection hole in a train wheel is a small hole located on the outer arc of the wheel hub. Its centerline is at a certain angle to the wheel centerline, and it usually has internal threads. It is mainly used for pressing and removing wheelsets, injecting high-pressure oil into an annular oil groove to ensure that the wheel and axle are not worn during pressing and disassembly. In the existing technology, the drilling equipment for machining oil injection holes is usually a radial drilling machine with angle adjustment fixtures. The fixtures need to be manually adjusted to tilt the wheel, and the machining of oil injection holes generally requires 5 to 6 steps to complete. It is entirely dependent on manual operation with the fixtures, which is labor-intensive. Wear on the angle adjustment mechanism and fixtures affects the machining accuracy. While machine tools that can automate the machining of oil injection holes include milling and turning centers, which can guarantee quality, these machine tools are expensive, and the cost of cutting tools is also high, placing a heavy burden on enterprises.
[0003] Existing technology includes a fixture titled "A Tooling for Machining Oil Injection Holes on Wheels," with publication number CN202752664 U. This technology comprises a base frame, a drill jig, and a clamping device. The base frame also includes a stop block fixed to it. The clamping device includes a screw and a nut, which secures the wheel to the base frame and the drill jig to the wheel. The bottom surface of the base frame is a flat plate, on which a triangular prism, or tripod, is fixedly mounted. The angle between the inclined surface of the tripod and the flat plate is such that when the wheel is placed on the inclined surface of the tripod, the direction of the oil injection hole to be machined is vertically upward. However, this technology is only suitable for machining oil injection holes on wheels of a single size and angle. It cannot meet the adjustment requirements of the angle of the oil injection hole for wheels of different radii, requiring repeated disassembly and clamping, and still necessitates manual angle adjustment, thus it is not an automated tooling. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a simple structure for machining inclined oil holes of train wheels of various models and sizes, which can conveniently and reliably realize the machining of inclined oil holes of various models and sizes, improve versatility, reduce equipment cost investment, greatly improve the level of automation, greatly improve production efficiency, and meet the actual needs of operation.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] This utility model is a processing device for inclined oil holes in train wheels. The rotating shaft is connected to the base plate, and multiple push cylinder sliding seats are set on the base plate. Each push cylinder sliding seat is equipped with a push cylinder, and a lifting and rotating oil cylinder is set on the push cylinder. The lifting and rotating oil cylinder is connected to a lifting and rotating pressure plate, and a drilling machine is set near the base plate.
[0007] The rotating shaft is mounted on the base, and a passive shaft is also provided on the base. The base plate connects both the passive shaft and the rotating shaft.
[0008] The push cylinder sliding seat is mounted in the T-groove of the base plate by a T-block, the push cylinder is mounted in the T-groove of the push cylinder sliding seat by a T-block, and a fixing nut is screwed on the push cylinder.
[0009] The aforementioned rotating pressure plate includes a top pressing surface, a middle connecting surface, and a bottom connecting surface, which together form a Z-shaped structure.
[0010] The inner sides of the passive shaft and the rotating shaft are respectively connected to L-shaped plates, and the L-shaped plates of the passive shaft and the rotating shaft are arranged symmetrically.
[0011] The base plate is fixedly connected to the L-shaped plate of the passive shaft and the L-shaped plate of the rotating shaft by screws.
[0012] The drilling machine includes a rotating lead screw and a lead screw nut assembly, and the drill bit is connected to the lead screw nut assembly.
[0013] The rotating shaft is mounted on a rotating shaft seat, the passive shaft is mounted on a passive shaft seat, and the rotating shaft is connected to a drive motor mounted on the rotating shaft seat.
[0014] The multiple push cylinder sliding seats on the base plate are arranged at intervals along the circumference, and each push cylinder sliding seat extends in a circular direction.
[0015] The passive shaft and the rotating shaft are respectively connected to the base via pads.
[0016] The working principle and beneficial effects of this utility model are as follows:
[0017] The train wheel inclined oil hole processing device of this utility model is equipped with a rotating shaft, which can rotate and is fixedly connected to a base plate. Therefore, controlling the rotation of the rotating shaft reliably realizes the rotation of the base plate, and the rotation angle of the base plate is controlled by controlling the rotation angle of the rotating shaft. Multiple push-cylinder sliding seats are set on the base plate, each with a push cylinder. To meet the positioning and processing requirements of inclined oil holes for different models and sizes of train wheels, each push-cylinder sliding seat is moved. Because the multiple push-cylinder sliding seats are arranged at intervals along the circumference, each extending in a circular direction, adjusting the position of the multiple push-cylinder sliding seats changes the diameter of the circle formed by the multiple push cylinders, thus meeting the processing requirements of different models and sizes of train wheels. A lifting and rotating hydraulic cylinder is set on the push cylinder, connected to a lifting and rotating pressure plate, which can perform lifting and rotating movements. A drilling machine is set near the base plate. The drilling machine is equipped with a drill bit, which can move horizontally, moving between near and away from the base plate. When drilling inclined oil holes for train wheels of the corresponding model and size, first adjust the position of each push cylinder sliding seat, then fix the push cylinder sliding seat, then adjust the position of the push cylinder again, and then fix the push cylinder. Place the train wheel on the multiple push cylinder sliding seats, control the positioning block of the push cylinder to extend horizontally, and control the positioning block of each push cylinder to abut against the side of the train wheel to achieve horizontal limitation of the train wheel. Then control the lifting and rotating pressure plate of the lifting and rotating cylinder to first extend upward, then rotate towards the train wheel, and then retract. At this time, each lifting and rotating pressure plate presses against the corresponding position above the train wheel to achieve vertical limitation of the train wheel. Then control the rotating shaft to rotate at the set angle, driving the base plate to rotate to the corresponding angle, and then control the movement of the machine tool drill bit. The drill bit approaches the position of the train wheel where the inclined oil hole needs to be processed until it is fully close, completing the processing of the inclined oil hole, and then the drill bit withdraws. Subsequently, the lifting and rotating pressure plate of the lifting and rotating cylinder is controlled to first extend upward, then rotate away from the train wheel, and then retract, releasing the vertical restriction on the train wheel. Then, the positioning block of the push cylinder is controlled to retract horizontally, releasing the horizontal restriction on the train wheel, thus completing the processing of the inclined oil hole. The degree of automation is high. Attached Figure Description

[0025] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0026] As attached Figure 1 -Appendix Figure 5As shown, this utility model is a processing device for oblique oil holes in train wheels. A rotating shaft 7 is connected to a base plate 3. Multiple push-cylinder sliding seats 5 are arranged on the base plate 3, each with a push cylinder 2. A lifting and rotating hydraulic cylinder 4 is mounted on each push cylinder 2, and the lifting and rotating hydraulic cylinder 4 is connected to a lifting and rotating pressure plate 6. A drilling machine is located near the base plate 3. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this structural design, a rotating shaft is provided, which can rotate. The rotating shaft 7 is fixedly connected to the base plate 3. Therefore, controlling the rotation of the rotating shaft reliably achieves the rotation of the base plate. The rotation angle of the base plate is controlled by controlling the rotation angle of the rotating shaft. The multiple push-cylinder sliding seats 5 on the base plate 3, each with a push cylinder 2, allow for the movement of each push-cylinder sliding seat 5 to meet the positioning and processing needs of oblique oil holes in train wheels of different models and sizes. Since the multiple push-cylinder sliding seats 5 are arranged with gaps along the circumference, each push-cylinder sliding seat 5 extends in a circular direction. The position of the multi-track pusher sliding seat 5 is adjusted to change the diameter of the circle formed by the multi-track pusher 2, thereby meeting the processing requirements of train wheels of different models and sizes. A lifting and rotating hydraulic cylinder 4 is installed on the pusher 2, which is connected to a lifting and rotating pressure plate 6. The lifting and rotating pressure plate 6 can perform lifting and rotating actions. A drilling machine is installed near the base plate 3. The drilling machine is equipped with a drill bit, which can move horizontally and can move between near and away from the base plate. When drilling the inclined oil hole 16 of the train wheel 15 of the corresponding model and size, first adjust the position of each push cylinder sliding seat 5, then fix the push cylinder sliding seat 5, then adjust the position of the push cylinder 2, then fix the push cylinder 2, place the train wheel 15 on the multiple push cylinder sliding seats 5, control the positioning block of the push cylinder 2 to extend horizontally, and the positioning block of each push cylinder 2 abuts against the side of the train wheel 15 to achieve horizontal limiting of the train wheel 15. Then control the lifting and rotating pressure plate 6 of the lifting and rotating oil cylinder 4 to first extend upward, then rotate towards the direction of the train wheel 15, and then retract. At this time, each lifting and rotating pressure plate 6 presses against the corresponding position above the train wheel 15 to achieve vertical limiting of the train wheel 15. Next, control the rotating shaft 7 to rotate at the set angle, causing the base plate 3 to rotate to the corresponding angle. The included angle between the drill bit and the base plate meets the set requirements. Then, control the movement of the machine tool's drill bit, bringing it close to the position on the train wheel 15 where the inclined oil hole 16 needs to be machined, until it is fully close, completing the machining of the inclined oil hole 16. The drilled inclined oil hole is in a horizontal state, and then the drill bit retracts. Subsequently, control the lifting and rotating pressure plate 6 of the lifting and rotating cylinder 4 to first extend upward, then rotate away from the train wheel 15, and then retract, releasing the vertical restriction on the train wheel 15. Then, control the positioning block of the push cylinder 2 to retract horizontally, releasing the horizontal restriction on the train wheel 15, completing the machining of the inclined oil hole 16.The train wheel inclined oil hole processing device described in this utility model has a simple structure and can conveniently and reliably process inclined oil holes for wheels of various models and sizes, improving versatility, reducing device cost, and significantly improving automation level and production efficiency to meet actual operational needs.
[0027] The rotating shaft 7 is mounted on the base 10, and a passive shaft 9 is also provided on the base 10. The base plate 3 is connected to both the passive shaft 9 and the rotating shaft 7. In this structure, the rotating shaft and the passive shaft cooperate to connect the base plate, and the rotation of the rotating shaft 7 controls the rotation angle of the base plate 3.
[0028] The push cylinder sliding seat 5 is secured in the T-slot of the base plate 3 by a T-block, and the push cylinder 2 is secured in the T-slot of the push cylinder sliding seat 5 by a T-block. A fixing nut 11 is screwed onto the push cylinder 2. With this structure, the push cylinder sliding seat 5 can move relative to the base plate, allowing adjustment of its relative position. The push cylinder can also move relative to the push cylinder sliding seat 5, allowing adjustment of its relative position. This effectively expands the applicability of the device, meeting the needs of wheels of different models and sizes.
[0029] The aforementioned rotating pressure plate 6 includes a top pressing surface 12, a middle connecting surface 13, and a bottom connecting surface 14, which form a Z-shaped structure. This structure allows the rotating pressure plate 6 to press or release the wheel.
[0030] The passive shaft 9 and the rotating shaft 7 are respectively connected to L-shaped plates 8 on their inner sides, and the L-shaped plates 8 of the passive shaft 9 and the rotating shaft 7 are arranged symmetrically. The base plate 3 is fixedly connected to the L-shaped plates 8 of the passive shaft 9 and the rotating shaft 7 by screws. The rotating shaft 7 is mounted on a rotating shaft seat, the passive shaft 9 is mounted on a passive shaft seat, and the rotating shaft 7 is connected to a drive motor mounted on the rotating shaft seat. With the above structure, the rotation angle of the rotating shaft 7 can be precisely controlled by controlling the rotation of the drive motor, thereby controlling the rotation angle of the base plate 3.
[0031] The drilling machine includes a rotating lead screw and a lead screw-nut assembly, with the drill bit connected to the lead screw-nut assembly. In this structure, the rotating lead screw is horizontally arranged, and the lead screw-nut assembly moves horizontally relative to the lead screw, thereby driving the drill bit to move horizontally and realize the machining of the inclined oil hole of the train wheel after it has been fixed in a position.
[0032] The multiple pusher cylinder sliding seats 5 on the base plate 3 are arranged at intervals along the circumference, and each pusher cylinder sliding seat 5 extends in a circular direction. The above structure allows for variations in the diameter of the circle formed by the multiple pusher cylinders 2, meeting the processing requirements of train wheels of different models and sizes.
[0033] The passive shaft 9 and the rotating shaft 7 are respectively connected to the base 10 via pads 1. In the above structure, the base is the foundation for setting up the corresponding components, and the pads 1 can be selected from pads of different heights.
[0034] The train wheel inclined oil hole processing device of this utility model is structurally designed with a rotating shaft 7 fixedly connected to a base plate 3. Therefore, controlling the rotation of the rotating shaft reliably rotates the base plate, and controlling the rotation angle of the base plate is achieved by controlling the rotation angle of the rotating shaft. Multiple push-cylinder sliding seats 5 are installed on the base plate 3, each with a push cylinder 2. To meet the positioning and processing requirements of inclined oil holes for different models and sizes of train wheels, each push-cylinder sliding seat 5 is moved. Because the multiple push-cylinder sliding seats 5 are arranged at intervals along a circumference, each extending in a circular direction, adjusting the position of the multiple push-cylinder sliding seats 5 changes the diameter of the circle formed by the multiple push cylinders 2, thus meeting the processing requirements of different models and sizes of train wheels. A lifting and rotating hydraulic cylinder 4 is installed on the push cylinder 2, connected to a lifting and rotating pressure plate 6, which can perform lifting and rotating actions. A drilling machine is installed near the base plate 3. The drilling machine is equipped with a drill bit that can move horizontally, moving between near and far from the base plate. When drilling the inclined oil hole 16 of a train wheel 15 of the corresponding model and size, first adjust the position of each push cylinder sliding seat 5, then fix the push cylinder sliding seat 5. Next, adjust the position of the push cylinder 2, then fix the push cylinder 2. Place the train wheel 15 on the multiple push cylinder sliding seats 5, control the positioning block of the push cylinder 2 to extend horizontally, with each positioning block of the push cylinder 2 pressing against the side of the train wheel 15, achieving horizontal limitation of the train wheel 15. Control the lifting and rotating pressure plate 6 of the lifting and rotating hydraulic cylinder 4 to first extend upwards, then rotate towards the train wheel 15, and then retract. At this time, each lifting and rotating pressure plate 6 presses against the corresponding position above the train wheel 15, achieving vertical limitation of the train wheel 15. Next, the rotating shaft 7 is controlled to rotate at a set angle, causing the base plate 3 to rotate to the corresponding angle. Then, the drill bit of the machine tool is controlled to move, bringing it close to the position of the train wheel 15 where the inclined oil hole 16 needs to be machined, until it is close enough to complete the machining of the inclined oil hole 16, and then the drill bit retracts. Subsequently, the lifting and rotating pressure plate 6 of the lifting and rotating cylinder 4 is controlled to first extend upward, then rotate away from the train wheel 15, and then retract, releasing the vertical restriction on the train wheel 15. Then, the positioning block of the push cylinder 2 is controlled to retract horizontally, releasing the horizontal restriction on the train wheel 15, completing the machining of the inclined oil hole 16. The degree of automation is high.
