Description

[0001] The utility model relates to the technical field of automatic oil injection, in particular to an automatic oil injection device for a gear box of an EMU. Background Art

[0002] Butter, also known as lubricating grease, is generally in a semi-solid state at room temperature. It is made by adding thickeners and additives to lubricating oil. The lubricating oil in lubricating grease is mainly mineral oil and synthetic lubricating oil. Because lubricating grease has good sealing and adhesion properties, and lubricating grease has a wide operating temperature range and long service life, it is usually used to lubricate bearings and gears.

[0003] At present, in industrial processing and production, grease is often added to the corresponding parts of the EMU gearbox by manual injection devices. However, since there are many parts of the EMU gearbox that need to be added with grease, the manual addition method will inevitably lead to low efficiency and affect production efficiency. At the same time, when using the manual injection method, workers are also required to add grease to the holes, gaps and connections at various positions on the EMU gearbox to ensure that all key parts of the EMU gearbox can be lubricated, reduce friction, and thus extend the service life of the EMU gearbox. Therefore, the existing method of manually injecting grease into the EMU gearbox not only greatly increases the injection difficulty and production cost, but also easily causes worker fatigue, which in turn leads to errors and omissions in the processing process, and ultimately affects product quality.

[0042] The technical solutions of the embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example

[0043] In this embodiment, in order to realize automatic oiling (buttering) of the EMU gearbox so that all key parts of the EMU gearbox can be lubricated and friction can be reduced, this example provides an EMU gearbox automatic oiling device, by installing an oil injection gun on the rotating arm of a multi-axis manipulator, connecting the input end of the oil injection gun with the output end of the oil storage tank, and simultaneously using an oil injection pump to pressurize the liquid inside the oil storage tank, squeezing the butter (lubricating grease) inside the oil storage tank onto the oil injection gun, and injecting the butter into various positions of the EMU gearbox through the oil injection gun. At the same time, the multi-axis manipulator is used to adjust the injection angle of the oil injection gun so that the butter can be flexibly injected into various positions of the EMU gearbox, thereby realizing automation.

[0044] It should be noted that the multi-axis manipulator can be a six-axis manipulator, a five-axis manipulator or a four-axis manipulator. The multi-axis manipulator can adjust the position of the injection oil gun at multiple angles and in multiple directions, so that the injection oil gun can inject butter at various positions. The manipulator is an automatic operating device that can imitate certain movement functions of human hands and arms to grasp, carry objects or operate tools according to a fixed program. It is characterized by being able to complete various expected operations through programming, and having the advantages of both human and mechanical machines in terms of structure and performance. In this case, the multi-axis manipulator is mainly used to carry objects or operate tools to achieve automatic Operating device; Generally, a manipulator consists of three main parts: an actuator, a drive mechanism, and a control system. The hand is used to grasp the workpiece (or tool). It has various structural forms, such as clamping, holding, and adsorption, depending on the shape, size, weight, material, and operation requirements of the grasped object. The motion mechanism enables the hand to complete various rotations (swings), movements, or combined movements to achieve the specified action and change the position and posture of the grasped object. The independent movement modes of the motion mechanism, such as lifting, retracting, and rotating, are called the manipulator's degrees of freedom. In order to grasp objects at any position and orientation in space, six degrees of freedom are required. Degrees of freedom are key parameters in manipulator design. The more degrees of freedom, the greater the manipulator's flexibility and versatility, and the more complex its structure. Generally, special-purpose manipulators have 2 to 3 degrees of freedom. The control system completes specific actions by controlling the motors of each degree of freedom of the manipulator. At the same time, it receives information fed back by sensors to form a stable closed-loop control. The core of the control system is usually composed of a microcontroller chip such as a single-chip microcomputer, which is programmed to achieve the desired function. Example

[0045] In this embodiment, in order to increase the flexibility of the automatic liquid injection device so that it can accurately add butter to various detailed positions of the EMU gearbox, this example also provides a mounting plate on the rotating arm. By installing the liquid injection oil gun on the mounting plate and providing a camera on the mounting plate, the central axis of the camera and the central axis of the liquid injection oil gun are located on the same plane, and the angle formed by the shooting direction of the camera and the central axis of the liquid injection oil gun is set to a constant angle; when the automatic liquid injection device is in use, the position of the component inside the EMU gearbox is located by shooting with the camera, and after accurately locating the position of the component, the rotating arm is controlled to rotate a certain angle so that the muzzle of the liquid injection oil gun corresponds to the component position, thereby achieving precise liquid injection, ensuring that the component position can be lubricated with butter, and reducing friction. At the same time, the rotating arm includes a rotating shaft. In this example, one side of the mounting plate is fixed to the rotating shaft, and the other side of the mounting plate is used to install the liquid injection oil gun, so that the liquid injection oil gun can always remain in an outward-facing state during actual use, so as to facilitate subsequent rotation adjustment, improve accuracy and freedom, and greatly improve the efficiency and convenience of injection at various positions.

[0046] It should be noted that in actual applications, in order to ensure that the multi-axis manipulator can execute with a high degree of freedom, the multi-axis manipulator in this example also includes a first manipulator arm, a second manipulator arm and a mounting base. By providing a rotating platform on the mounting base, one end of the second manipulator arm is fixed on the rotating platform, so that the other end of the second manipulator arm is hinged to one end of the first manipulator arm, and the other end of the first manipulator arm is hinged to the rotating arm, thereby realizing multi-degree-of-freedom adjustment of the liquid injection gun. At the same time, under the control of multiple degrees of freedom, the liquid injection gun and camera on the mounting plate can flexibly add butter to various positions inside the EMU gearbox, such as holes, gaps and connections, from multiple angles and directions, greatly improving the efficiency and precision of the industry, and improving the production quality and production efficiency of the EMU gearbox.

[0047] It is worth noting that in this example, the angle formed by the central axis of the camera and the central axis of the liquid injection gun is a right angle, and the angle can be a straight angle or any acute angle or obtuse angle. The angle is to ensure that when the liquid injection gun is adjusted, the mounting plate can be rotated and adjusted based on the angle, so that after the injection position is determined, the mounting plate is immediately rotated to the corresponding angle, so that the liquid injection gun can accurately correspond to the determined injection position; wherein, in this example, the angle formed by the central axis of the camera and the central axis of the liquid injection gun is set to a right angle, in order to facilitate, quickly and conveniently adjust the liquid injection gun, so as to improve injection efficiency and reduce injection errors. Example

[0048] In this embodiment, in order to be able to adjust the camera to improve the pixel clarity of the image taken by the camera and ensure the stability of the liquid injection gun, this example also provides a first mounting seat and a second mounting seat on the mounting plate. By fixing the camera on the first mounting seat and the liquid injection gun on the second mounting seat, and making the first mounting seat adjacent to the second mounting seat, a fixing plate is also provided on the mounting plate, and a mounting through hole is provided on the fixing plate, and the liquid injection gun is fixed on the mounting through hole; so that both the camera and the liquid injection gun can be stably fixed on the mounting plate, thereby ensuring the accuracy of butter injection.

[0049] In addition, in this example, in order to ensure that the camera can clearly capture and locate the position to be injected, an annular flat plate is also provided on the mounting plate. A shooting through hole is provided in the center of the annular flat plate, so that the shooting through hole is aligned with the shooting port of the camera to ensure that the light of the camera can be better converged when shooting. At the same time, the shooting through hole can accurately correspond to the position of the component to be injected, thereby improving the shooting accuracy of the camera.

[0050] It is worth noting that in order to be able to adjust the camera position, shorten or extend the distance between the camera and the annular plate, and improve the flexibility of camera shooting, this example also provides an adjustment plate on one side of the first mounting seat, by providing a screw hole on the adjustment plate, installing a bolt on the screw hole, and providing a rotating plate at one end of the bolt, aligning the other end of the bolt with the back of the camera, and setting the central axis of the bolt to coincide with the central axis of the camera to ensure that the shooting direction of the camera can be aligned, and adjusting the position of the bolt by rotating the rotating plate, and then pushing and adjusting the position of the camera by the bolt, thereby achieving the goal of shortening or extending the distance between the camera and the annular plate.
