Description

Technical Field

[0001] This invention relates to the technical field of scribing and measuring tools, specifically to a tool for scribing and measuring the position of a pipe end cap. Background Technology

[0002] Marking and measuring tools are specialized equipment used to mark machining or measuring reference lines on the surface of workpieces. They are widely used in fields such as machinery manufacturing, pipeline engineering, and building decoration.

[0003] Existing scribing and measuring tools are difficult to calculate the arc length directly due to the curvature of the end cap, making it inconvenient to measure the position of the end cap opening. Traditional scribing requires multiple adjustments of the baseline using tools such as theodolites and levels, combined with manual measurement of the opening position using steel rulers and templates. For example, when locating the opening on an elliptical end cap, the center point must be determined first, and then reference points must be marked step by step along the curvature direction. This process is time-consuming and depends on the operator's experience. Changes in curvature may cause the measuring tool to not fit tightly against the curved surface, requiring frequent adjustments to the tool position or the use of auxiliary supports, further reducing efficiency. The operation is complex and prone to errors.

[0004] Therefore, it is necessary to invent a tool for marking and measuring the position of the end cap pipe to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tool for marking and measuring the position of the end cap, so as to solve the problem that it is difficult to directly calculate the arc length due to the curvature of the end cap, and the measurement of the position of the end cap is inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tool for marking and measuring the position of a capped pipe opening, comprising a suction cup, a connecting rod, a first azimuth disc, a second azimuth disc, a rotating shaft, a horizontal scale, a spirit level, a telescopic rod, and a pen tip. The suction cup has a connecting rod at its top, a first azimuth disc at one end of the connecting rod, a second azimuth disc above the first azimuth disc, a rotating shaft between the second azimuth disc and the first azimuth disc, a horizontal scale on one side of the outer wall of the rotating shaft, a spirit level on one side of the inner wall of the horizontal scale, a telescopic rod below one end of the horizontal scale, and a pen tip at the lower end of the telescopic rod. There are three suction cups, and three connecting rods are installed corresponding to the position and number of suction cups.

[0007] The outer wall of the first azimuth disk is provided with a fixing sleeve, and the fixing sleeve is set according to the number of connecting rods.

[0008] The connecting rod is designed in an I-shape, and one end of the fixing sleeve has an I-shaped groove that matches the connecting rod when inserted.

[0009] A pointer is provided at the center of the bottom surface of the first azimuth disc, and the pointer is aligned with the centerline of the end cap to be measured. The suction cup is fixed to the end cap to be measured.

[0010] The horizontal scale is adjusted according to the position of the first and second azimuth discs, which are rotated via a pivot.

[0011] Both the first and second azimuth dials have 0-360° angle scales. When the rotating shaft rotates, it drives the horizontal scale to rotate. The horizontal scale has scales, and when it is placed at the center of the end cap to be measured, the scale is 0.

[0012] The level needs to be adjusted to a horizontal position during measurement. The telescopic rod is adjusted to extend or retract according to the position of the end cap to be measured, and the pen tip at the bottom of the telescopic rod is used to draw lines on the end cap to be measured.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This end cap nozzle position marking and measuring tool allows for simple and quick measurement of the nozzle position on an end cap. Three suction cups are fixed to the end cap to be measured, utilizing triangular stability to ensure tool stability. The pointer in the center of the bottom surface of the first azimuth disc is aligned with the centerline of the end cap, providing a precise reference for subsequent measurement and marking, avoiding measurement errors caused by inaccurate positioning. Precise angle scales allow users to easily read the current angle value, thus accurately determining the nozzle position angle. A horizontal ruler is installed on one side of the internal horizontal scale; when measuring distances, the user can adjust the horizontal ruler to ensure it is level, avoiding distance measurement errors caused by tilting the horizontal ruler, ensuring the accuracy and reliability of the measurement results. This marking method is simple and quick, greatly improving work efficiency and reducing the time and labor intensity of manual marking. It ensures the complete functionality of the tool while being easy to carry and store. Users can easily assemble and disassemble the tool on-site, making it convenient and quick.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-5 The tool shown includes a suction cup 1, a connecting rod 2, a first azimuth plate 3, and a second azimuth plate 4. The top of the suction cup 1 is provided with the connecting rod 2, and one end of the connecting rod 2 is provided with the first azimuth plate 3. There are three suction cups, and three connecting rods 2 are installed according to the position and number of suction cups 1. The outer wall of the first azimuth plate 3 is provided with a fixing sleeve, which is set according to the number of connecting rods 2. The connecting rod 2 is I-shaped. One end of the fixing sleeve has an I-shaped groove that matches the connecting rod 2. A pointer is provided in the middle of the bottom surface of the first azimuth plate 3. The pointer is aligned with the center line point of the end cap to be measured. The suction cup 1 is fixed to the end cap to be measured. The second azimuth plate 4 is provided above the first azimuth plate 3. A rotating shaft 5 is provided between the second azimuth plate 4 and the first azimuth plate 3. A horizontal scale 6 is installed on one side of the outer wall of the rotating shaft 5, and a horizontal ruler 7 is installed on the inner side of the horizontal scale 6. A telescopic rod 8 is installed below one end of the horizontal scale 6, and a pen tip 9 is installed at the lower end of the telescopic rod 8. The horizontal scale 6 is adjusted according to the position of the first azimuth disc 3 and the second azimuth disc 4. The first azimuth disc 3 and the second azimuth disc 4 are rotated by the rotating shaft 5. Both the first azimuth disc 3 and the second azimuth disc 4 have 0-360° angle scales. When the rotating shaft 5 rotates, it drives the horizontal scale 6 to rotate. The horizontal scale 6 has scales, and the scale is 0 when it is placed at the center of the end cap to be measured. The horizontal ruler 7 needs to be adjusted to a horizontal state when measuring. The telescopic rod 8 is adjusted to extend and retract according to the position of the end cap to be measured, and the pen tip 9 at the bottom of the telescopic rod 8 is used to draw lines on the end cap to be measured. The working principle of this practical application is as follows: Refer to the instruction manual appendix Figure 1-5When using this type of end cap nozzle position marking and measuring tool, firstly, three suction cups 1 are attached and fixed to the end cap to be measured. The tool's stable position on the end cap is determined by these three fixed points. Connecting rod 2 is installed corresponding to the positions of the suction cups 1, serving a connecting and supporting function. The first azimuth disc 3 is mounted on the connecting rod 2 via a fixing sleeve. The pointer at the center of its bottom surface is aligned with the centerline point of the end cap to be measured, achieving precise positioning of the tool on the end cap and providing a reference for subsequent measurement and marking. Both the first azimuth disc 3 and the second azimuth disc 4 have 0-... The 360° azimuth scale has a second azimuth disc 4 mounted above the first azimuth disc 3 via a rotating shaft 5. It can rotate around the shaft 5. By rotating the second azimuth disc 4, the required angle position can be accurately measured and determined according to its angle with the first azimuth disc 3 to meet the angle requirements of the pipe opening. A horizontal scale 6 is mounted on one side of the outer wall of the rotating shaft 5 and can rotate with it. It has graduations, with the graduation at 0 when placed at the center of the end cap to be measured. Once the angle is determined, the horizontal scale 6 can measure the distance from the center of the end cap to the pipe opening. A horizontal ruler 7 is set... Inside the horizontal scale 6, during the measurement process, the horizontal scale 7 needs to be adjusted to a horizontal state to ensure that the horizontal scale 6 is in a horizontal position, thereby ensuring the accuracy of the distance measurement. The telescopic rod 8 is installed below one end of the horizontal scale 6 and can be extended and retracted according to the position of the end cap to be measured. The pen tip 9 is installed at the lower end of the telescopic rod 8. After determining the angle and distance of the pipe opening position, adjust the telescopic rod 8 to make the pen tip 9 contact the surface of the end cap. Then move the tool or keep the tool stable and rotate the end cap, depending on the specific situation, and you can draw the line of the pipe opening position on the end cap. When using this device, first place the tool on top of the end cap, align the pointer at the bottom of the tool with the center point of the end cap, adjust the suction cup 1 so that the suction cup 1 can be firmly fixed on the end cap, rotate the adjusting thread to keep the horizontal scale 6 horizontal, rotate the horizontal scale 6 according to the two orientation dials, measure whether the position of the angle line is equal to the scale, keep the horizontal scale 6 horizontal while rotating, adjust the telescopic rod 8 to the specified scale of the horizontal scale according to the distance of the pipe opening from the center point of the end cap, and then lower the telescopic rod 8 until the pen tip 9 touches the outer surface of the end cap, this position is the pipe opening position.
