[0027] Example
[0028] The utility model provides a marking tool for the oil level observation window of the gear box of an EMU, which is used to solve technical problems. The marking tool for the oil level observation window of the gear box of an EMU comprises a marking plate 1:
[0029] like Figure 1-2 As shown, a guide groove 11 is provided at one end of the scribed plate 1, and the guide groove 11 extends from one end of the scribed plate 1 to the other end to form a guide path. A plurality of first scribed grooves 12 are provided on the groove wall on either side of the guide groove 11. One end of the first scribed groove 12 is directly connected to the guide groove 11 to form an opening for the entry of the scribed knife. In particular, the first scribed groove 12 passes through the scribed plate 1 to ensure that the scribed knife can pass through the scribed plate 1 without hindrance and directly contact the surface of the observation window 2 to be scribed. When in use, the scribed plate 1 is first fixed to the observation position, and then the scribed knife is used to accurately align the tip of the knife with the opening of any first scribed groove 12 under the guidance of the guide groove 11 and insert it. The scale line penetrates the scale plate 1 and directly contacts the surface of the observation window 2, and then continues to move along the first scale groove 12. As the scale knife moves, the scale knife carves a continuous scale line on the surface of the observation window 2. By repeating this process, multiple scale lines are engraved on the observation window 2 using the first scale grooves 12 distributed at different positions of the guide groove 11. After the engraving is completed, the surface of the observation window 2 will present multiple clearly visible scale lines. The multiple first scale grooves 12 are evenly distributed along the extension direction of the guide groove 11. Maintenance personnel only need to use the scale lines on the observation window 2 to intuitively judge whether the current oil level is within the normal range, without disassembling the box or relying on other complex tools, which greatly improves work efficiency and accuracy.
[0030] like Figure 1-3As shown, the scale plate 1 is further provided with a fixing groove 14, which passes through both sides of the scale plate 1 and is located on one side of the guide groove 11. The extension direction of the fixing groove 14 is parallel to the extension direction of the guide groove 11, and the fixing groove 14 and the guide groove 11 pass through the same end of the scale plate 1; when it is necessary to mark the observation window 2, first accurately align the scale plate 1 and insert it into the preset position of the gearbox oil level observation window 2, and the gearbox is provided with a mounting bolt 3 for fixing the observation window 2 or other components. The installation inside the gearbox is as follows: The bolt 3 slides along the track of the fixing groove 14 until it reaches the bottom of the fixing groove 14. The process of the installation bolt 3 sliding along the fixing groove 14 to the bottom of the groove completes the positioning of the scale plate 1, ensuring that the scale plate 1 can be accurately in the same position each time the line is engraved, thereby ensuring the accuracy of the engraved position. At the same time, the installation bolt 3 can fix the scale plate 1 at the bottom of the groove, effectively limiting the shaking of the scale plate 1, making the subsequent engraving operation more stable, thereby facilitating the installation and fixation of the scale plate 1, and improving the accuracy and efficiency of the engraving operation.
[0031] The grating plate 1 is fixed to the bottom of the gearbox 14 so that the grating plate 1 is fixed to the bottom of the gearbox 14 and the grating plate 1 is inserted into the gearbox 2. The grating plate 1 is fixed to the bottom of the gearbox 14 and the grating plate 1 is inserted into the gearbox 2. The grating plate 1 is fixed to the bottom of the gearbox 14 and the grating plate 1 is inserted into the gearbox 2. The grating plate 1 is fixed to the bottom of the gearbox 14 so that the grating plate 1 is fixed to the bottom of the gearbox 14 so that the grating position is the same each time. The grating plate 1 is fixed to the bottom of the gearbox 14 so that the grating position is the same each time. The grating plate 1 is fixed to the bottom of the gearbox 14 and the grating plate 1 is fixed to reduce the shaking of the grating plate 1, so as to facilitate grating. The grating knife is then used to make the grating groove contact with the surface of the grating window 2 and move along the first grating groove 12 to grating the surface of the grating window 2. The grating is then made in the remaining first grating grooves 12 in sequence to complete the grating of the grating window 2. Therefore, the gearbox oil level observation window engraving tool of the EMU is slid along the fixing groove 14 to the bottom of the fixing groove 14 by installing the bolt 3, fixing the engraving plate 1 to reduce the shaking of the engraving plate 1, and the engraving knife moves along the first engraving groove 12 to engrave the scale lines, making it easy to engrave the scale lines on the gearbox observation window 2 panel and reducing the scratches on the mirror surface of the observation window 2 by the engraving knife during engraving.
[0032] An optional implementation of this embodiment is as follows: Figure 1-2As shown, when the scribed plate 1 is used to make lines, the first scribed groove 12 is parallel to the horizontal plane. Specifically, when the scribed plate 1 is used to make lines, when the scriber moves along the first scribed groove 12 and carves the scale lines on the surface of the observation window 2, the scale lines will be horizontal and parallel to the oil level inside the fuel tank. That is, the extension direction of the first scribed groove 12 and the fixed groove 14 can be customized according to the specific conditions of different fuel tanks. When the position, tilt angle, and oil level monitoring requirements of the observation windows 2 of different fuel tanks may vary, the extension direction of the scribed groove and the fixed groove 14 can be adjusted to ensure that the scale lines can accurately reflect the oil level height when the angle of the observation window 2 changes, thereby providing intuitive oil level information. As shown in the figure, in one implementation provided by this embodiment, the angle between the fuel tank observation window 2 and the horizontal plane is α, α=217°. Therefore, after the scale lines on the fuel tank observation window 2 are marked, the scale lines are horizontal and parallel to the oil level in the fuel tank, making it easier to determine the oil level based on the scale lines.
[0033] An optional implementation of this embodiment is as follows: Figure 1-2 As shown, a second scored groove 13 is provided on the groove wall of the guide groove 11 away from the second scored groove 13. The second scored groove 13 increases the density of the scale lines, making the scale lines denser and more evenly distributed, thereby providing a more precise oil level indication. One end of each second scored groove 13 is connected to the guide groove 11 to facilitate the entry of the scoring knife. Each second scored groove 13 runs through both sides of the scoring plate 1 so that the scoring knife can pass through the second scored groove 13 and abut against the surface of the observation window 2 to be scored. When scoring the observation window 2 in the second scored groove 13, first, fix the scoring plate 1 in an appropriate position, and the mounting bolt 3 inside the gear box slides along the trajectory of the fixing groove 14 until it reaches the bottom of the fixing groove 14. , complete the positioning of the scoring plate 1, insert the scoring knife from one end of the guide groove 11, and slide it along the guide groove 11 to the position of the second scoring groove 13 where the required scoring is required, apply pressure to the scoring knife to move the scoring knife along the trajectory of the second scoring groove 13. During the movement, the scoring knife maintains close contact with the surface of the observation window 2, thereby leaving scale lines on the observation window 2, repeat the above steps, perform scoring operations on different second scoring grooves 13, until all scale lines are completed, and multiple second scoring grooves 13 are evenly distributed along the extension direction of the guide groove 11 to engrave multiple parallel and equidistant scale lines on the observation window 2. After completing the engraving of the scale lines, the oil level of the gearbox can be intuitively judged by the scale lines on the observation window 2.
[0034] An optional implementation of this embodiment is as follows: Figure 1-2As shown, when the marking plate 1 is used for marking, any second marking groove 13 is parallel to the horizontal plane. As shown in the figure, the angle between the oil tank observation window 2 and the horizontal plane in an implementation manner provided in this embodiment is β, β = 37°. During the marking process, the marking knife moves along the trajectory of the second marking groove 13 to mark the surface of the observation window 2. Since the second marking groove 13 itself is parallel to the horizontal plane, horizontal scale lines are left on the observation window 2. After these scale lines are marked, the scale lines are parallel to the oil level in the oil tank. When the oil level in the oil tank rises or falls, the operator only needs to observe the relative position of the scale lines and the oil level to quickly and accurately determine the current oil level.
[0035] An optional implementation of this embodiment is as follows: Figure 1-2 As shown, the first scored groove 12 corresponds to the second scored groove 13 one by one, and the corresponding first scored groove 12 and the second scored groove 13 extend in the same direction, that is, the corresponding first scored groove 12 and the second scored groove 13 are located at the same height. After using a scoring knife to carve scale lines in the corresponding first scored groove 12 and the second scored groove 13, the scale lines corresponding to the first scored groove 12 and the second scored groove 13 are used to indicate the same height, so that the oil level in the current gearbox can be observed more intuitively.
[0036] An optional implementation of this embodiment is as follows: Figure 1-2 As shown, the spacing between adjacent first scale grooves 12 or second scale grooves 13 is equal, thereby achieving an equidistant distribution of scale lines on the observation window 2. The equidistant distribution of scale lines reduces reading errors because each scale line represents a fixed oil level, so that the operator can more accurately judge the height of the oil level. At the same time, the equidistant distribution of scale lines is more neat visually. It is worth noting that this embodiment illustrates that the spacing between adjacent first scale grooves 12 or second scale grooves 13 is equal. In actual applications, the size of the spacing between adjacent first scale grooves 12 or second scale grooves can also be adjusted according to usage requirements. Specifically, when a higher precision oil level reading is required, the spacing between adjacent scale grooves can be reduced. When the reading does not require high precision, the spacing can be increased to reduce the difficulty of marking.
[0037] An optional implementation of this embodiment is as follows: Figure 1-2 As shown, the bottom of the fixing groove 14 is arc-shaped, and the width of the fixing groove 14 matches the mounting bolt 3 inside the gear box. When the mounting bolt 3 inside the gear box slides along the fixing groove 14 to the bottom of the fixing groove 14, the mounting bolt 3 abuts against the bottom of the fixing groove 14. The arc-shaped bottom of the groove can have a larger contact area with the mounting bolt 3, thereby better fixing the scale plate 1.
[0038] An optional implementation of this embodiment is as follows: Figure 1-2 As shown, there are two fixing grooves 14, which are respectively located on both sides of the guide groove 11, and the first engraved groove 12 and the second engraved groove 13 are located between the fixing groove 14 and the guide groove 11. The two fixing grooves 14 are respectively used to pass different mounting bolts 3, and the first engraved groove 12 and the second engraved groove 13 are located between the fixing groove 14 and the guide groove 11. The two fixing grooves 14 are respectively located on both sides of the guide groove 11. When the mounting bolts 3 slide to the bottom of the groove along the trajectory of the fixing groove 14, the engraved plate 1 is fixed. Since there are two fixing grooves 14 and they are respectively located on both sides of the guide groove 11, the engraved plate 1 can maintain balance during the installation process, reducing the offset or tilt caused by uneven force on one side. The first engraved groove 12 and the second engraved groove 13 are located between the fixing groove 14 and the guide groove 11 to facilitate the engraving of the scale lines.
[0039] In summary, when the observation window 2 of the gearbox oil level observation window of the EMU gearbox needs to be engraved, the engraved plate 1 is placed in the gearbox so that the engraved plate 1 is close to the observation window 2, and the engraved plate 1 is inserted into the position of the gearbox oil level observation window 2. The mounting bolt 3 inside the gearbox slides along the fixing groove 14 to the bottom of the fixing groove 14, and the mounting bolt 3 abuts against the bottom of the fixing groove 14. The arc-shaped bottom of the groove can have a larger contact area with the mounting bolt 3, thereby better fixing the engraved plate 1, so that when the observation window 2 needs to be engraved, the engraved plate 1 can be better fixed. When marking, the marking plate 1 is in the same position, so that the marking position is the same each time. At the same time, the mounting bolt 3 slides along the fixing groove 14 to the bottom of the fixing groove 14 to fix the marking plate 1, reducing the shaking of the marking plate 1, thereby facilitating marking. Then, a marking knife is used, with the marking groove abutting against the surface of the observation window 2, and moving along the first marking groove 12 and the second marking groove 13, so as to mark the surface of the observation window 2, and then the remaining first marking grooves 12 and second marking grooves 13 are marked in turn to complete the marking of the observation window 2. Therefore, the EMU gearbox oil level observation window marking fixture slides along the fixing groove 14 to the bottom of the fixing groove 14 by the mounting bolt 3, fixes the marking plate 1, reduces the shaking of the marking plate 1, and moves the marking knife along the first marking groove 12 and the second marking groove 13 to mark the scale lines, making it easy to mark the scale lines on the gearbox observation window 2 panel and reducing the scratches on the mirror surface of the observation window 2 by the marking knife.
