Detailed Implementation
[0018] The gearbox flange connection hole processing equipment proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, only for the purpose of conveniently and clearly illustrating the embodiments of this utility model. Please refer to the drawings to make the purpose, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.
[0019] Traditional shaft alignment and reaming fixtures typically use a clamp. During operation, the clamp is installed on one of the two shafts to be connected (the installation position should avoid the arc transition area between the flange and the shaft root). Then, the boring machine is installed on the clamp, and the boring machine performs reaming on the hole on the flange.
[0020] However, machining the flange connection holes of special ship gearboxes is difficult using traditional shaft alignment reaming tooling. For example... Figure 1As shown, for special marine gearboxes, the gearbox output shaft 4 and the rubber joint coupling 6 are connected. Specifically, they are connected by a gearbox flange 41 on the gearbox output shaft 4 and a rubber joint coupling flange 61 on the rubber joint coupling 6. The flange connection holes 7 aligned on the gearbox flange 41 and the rubber joint coupling flange 61 are the holes to be machined. Since most of the gearbox output shaft 4 is inside the gearbox housing 5 and is blocked by the gearbox housing 5, it is impossible to machine the flange connection holes 7 from the side of the gearbox output shaft 4. It can only be machined from the side of the rubber joint coupling 6 connected to the gearbox output shaft 4. The rubber joint coupling 6 is a short shaft. The distance between the flanges on both sides of this short shaft (i.e., the length L of the short shaft) is only 280mm, which is a very small space. A standard boring machine cannot be installed on this short shaft. Furthermore, the total thickness of the gearbox flange 41 and the rubber joint coupling flange 61 after connection is 95mm. Since reaming involves rough boring and finish boring, a certain distance must be reserved for tool changes. Therefore, the stroke of the reaming machine must be at least 190mm. This means the distance from the reaming machine to the other flange of the rubber joint coupling 6 is only 90mm, which is very close. In addition, as... Figure 2 As shown, the diameter of the flange connection hole 7 to be machined is 34mm. The distance from the center of the flange connection hole 7 to the outer circle of the flange is only 45mm, so the distance from the outer circle of the flange connection hole 7 to the outer circle of the flange is only 28mm. This leaves insufficient operating space for a conventional boring machine. Although manual reaming is possible, the perpendicularity of the hole cannot be guaranteed after manual reaming, and the workload of manual reaming is extremely large.
[0021] In order to enable the machining of flange connection holes for gearbox flanges and rubber joint coupling flanges in extremely small spaces, this utility model provides a gearbox flange connection hole machining equipment.
[0022] like Figures 3-5 As shown, the processing equipment includes: a clamp 1 for fixing and supporting the entire processing equipment, the clamp 1 being mounted on a transmission component (such as the rubber joint coupling 6 in this embodiment) connected to the gearbox output shaft 4; a feed mechanism 2 mounted on the clamp 1 for providing the feed motion required during equipment processing; and a processing mechanism 3 mounted on the clamp 1 for providing the rotational motion required during equipment processing; the feed mechanism 2 and the processing mechanism 3 are connected.
[0023] Among them, such as Figure 4 and Figure 5As shown, the feeding mechanism 2 includes a first housing 21, a first stepper motor 22, a screw 23, a guide rod 24, a limiting block 25, and a fixing plate 26. The limiting block 25 is connected to the front end face of the clamp 1, and the fixing plate 26 is connected to the rear end face of the clamp 1. The first housing 21 is disposed between the limiting block 25 and the fixing plate 26, and the feeding mechanism 2 is connected to the processing mechanism 3 through the first housing 21. The screw 23 and the guide rod 24 both pass through the first housing 21. One end of the screw 23 is rotatably connected to the limiting block 25, and the other end is rotatably connected to the fixing plate 26; one end of the guide rod 24 is fixedly connected to the limiting block 25, and the other end is fixedly connected to the fixing plate 26. The axes of the screw 23 and the guide rod 24 are parallel to the central axis of the clamp 1. The first stepper motor 22 is disposed on the first housing 21. A first gear structure is provided inside the first housing 21, and the first gear structure is connected to the first stepper motor 22 and the screw 23 respectively. The wall of the hole through which the screw 23 passes inside the first housing 21 is provided with an internal thread, which meshes with the screw 23. In the description of this utility model, "front" refers to the direction facing the flange connection hole 7 after the processing equipment is installed on the rubber joint coupling 6, and "rear" refers to the direction away from the flange connection hole 7 after the processing equipment is installed on the rubber joint coupling 6.
[0024] The first stepper motor 22 provides power and transmits it to the screw 23 through a first gear structure located inside the first housing 21, driving the screw 23 to rotate. Since the two ends of the screw 23 are axially fixed, when it rotates, the first housing 21 generates a linear displacement along the axial direction of the screw 23 through the internal thread meshing with the screw 23. The machining mechanism 3 connected to the first housing 21 will move linearly synchronously with the first housing 21, thereby driving the tool mounted on the machining mechanism 3 to perform machining feed motion. The guide rod 24 plays a guiding role, ensuring that the first housing 21 and the machining mechanism 3 move smoothly in a straight line without rotation or shaking, ensuring the straightness and accuracy of the feed motion. The limiting block 25, while fixing the screw 23 and the guide rod 24, can also limit the range of movement of the first housing 21 and the machining mechanism 3.
[0025] Among them, such as Figures 3-5As shown, the processing mechanism 3 includes a second housing 31, a second stepper motor 32, and a tool holder 33. The second housing 31 is used to mount the various components of the processing mechanism 3 and is fixedly mounted on the first housing 21. The tool holder 33 is located at the lower end of the second housing 31, and its lower surface slides in contact with the clamp 1. The second stepper motor 32 is mounted on the second housing 31. The second housing 31 can move linearly along with the first housing 21, thereby driving the tool holder 33 to move linearly synchronously.
[0026] The tool holder 33 is provided with a sleeve 331 for mounting the tool. A second gear structure is provided inside the second housing 31, and the second gear structure is connected to both the second stepper motor 32 and the sleeve 331. The second stepper motor 32 provides power and transmits it to the sleeve 331 in the tool holder 33 through the second gear structure inside the second housing 31, driving the sleeve 331 to rotate, thereby causing the tool to rotate and machine the flange connection hole.
[0027] The specific structures of the first gear structure and the second gear structure are both existing technologies and can be easily implemented by those skilled in the art.
[0028] Among them, such as Figure 3 and Figure 4 As shown, a semi-circular groove 11 is formed on the clamp 1. The axis of the semi-circular groove 11 is parallel to the central axis of the clamp 1. The tool holder 33 is embedded in the semi-circular groove 11, and the lower surface of the tool holder 33 slides in contact with the groove wall of the semi-circular groove 11 of the clamp 1. When the first stepper motor 22 is started, the tool holder 33 follows the first housing 21 and moves linearly along the axial direction of the semi-circular groove 11. The semi-circular groove 11 can enlarge the contact surface between the clamp 1 and the tool holder 33, playing a stabilizing and auxiliary guiding role during the linear movement of the tool holder 33.
[0029] When using the above-mentioned processing equipment, the clamp 1 is installed on the rubber joint coupling 6. The front end face of the clamp 1 and the limiting block 25 are together in contact with the flange 61 of the rubber joint coupling. The cutting tool is installed in the sleeve 331 of the cutting tool holder 33 and aligned with the flange connection hole 7 to be processed. After the first stepper motor 22 and the second stepper motor 32 are started, the first stepper motor 22 drives the first housing 21 to move linearly, thereby driving the second housing 31, the cutting tool holder 33 connected to the second housing 31, the sleeve 331 set inside the cutting tool holder 33, and the cutting tool installed in the sleeve 331 to move linearly synchronously. The second stepper motor 32 drives the sleeve 331 in the cutting tool holder 33 to move rotatingly. The cutting tool moves synchronously with the sleeve 331. Therefore, the cutting tool performs linear feed and rotational processing at the same time to complete the processing operation of the flange connection hole 7.
