Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and testing technology, specifically to an auxiliary device for measuring the distance between the end faces of a container head. Background Technology

[0002] In the manufacturing and installation of equipment such as pressure vessels, boilers, and storage tanks, the assembly and welding of the end caps to the shell is a critical process. The distance and perpendicularity between the end cap end face and the theoretical reference plane (usually the shell end face or axis) are crucial quality indicators, directly affecting the assembly accuracy, stress state, and operational safety of the equipment. Currently, traditional methods are mostly used to measure the distance and perpendicularity of the end cap end face, such as using large calipers, plumb bobs with a steel ruler, or using a laser rangefinder to measure at multiple points and then calculate.

[0003] These methods have the following drawbacks: 1. Cumbersome operation and low efficiency: They require multiple people to cooperate, repeatedly locate and read values, and measuring a single point is time-consuming. 2. Accuracy is greatly affected by human factors: Especially the plumb bob method, which is prone to errors due to wind or operator shaking. 3. Poor adaptability: For large heads, traditional measuring tools are difficult to fix, and the benchmark is difficult to unify, resulting in large cumulative errors. 4. Limited functionality: Many methods can only measure distance or only roughly judge perpendicularity, and cannot quickly combine the two. Therefore, there is an urgent need for a dedicated auxiliary tool that can quickly, accurately, and reliably measure the distance and perpendicularity of the end face of a container head. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problems of cumbersome operation, low efficiency, need for multiple people to cooperate, repeated positioning and reading, and long time consumption in measuring a single point in the existing technology, thereby providing an auxiliary device for measuring the distance of the end face of a container.

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary device for measuring the distance between the end faces of a container head, comprising: a magnetic base disposed on the end face of the container head, wherein an adjustable support frame is provided on the magnetic base and the adjustable support frame is rotatably connected to the magnetic base; and a measuring structure disposed on the magnetic base via a first clamping mechanism, wherein a horizontal detection structure is provided on the measuring structure and the horizontal detection structure is slidably connected to the measuring structure, the horizontal detection structure being used to detect the levelness of the measuring structure.

[0006] Furthermore, the adjustable support frame includes a first support rod and a second support rod, the first support rod being perpendicularly disposed on the magnetic base, and the second support rod being rotatably connected to the first support rod.

[0007] Furthermore, the first and second support rods are made of telescopic rod structure.

[0008] Furthermore, the first support rod and the second support rod are composed of multiple rod segments connected together.

[0009] Furthermore, there are two first clamping mechanisms, which are symmetrically arranged in the middle of the measuring structure.

[0010] Furthermore, the horizontal detection structure has two parts, which are respectively located on the top and side wall of the measuring structure.

[0011] Furthermore, the horizontal detection structure is mounted on the measuring structure via a second clamping mechanism.

[0012] Furthermore, both the first clamping mechanism and the second clamping mechanism are universal locking clamps.

[0013] Furthermore, the measuring structure is a steel ruler.

[0014] Furthermore, the detection structure is a horizontal detector.

[0015] The technical solution of this utility model has the following advantages: 1. The auxiliary device for measuring the distance between the end faces of a container head provided by this utility model includes: a magnetic base disposed on the end face of the container head, wherein an adjustable support frame is provided on the magnetic base and the adjustable support frame is rotatably connected to the magnetic base; a measuring structure disposed on the magnetic base via a first clamping mechanism, and a horizontal detection structure is provided on the measuring structure, wherein the horizontal detection structure is slidably connected to the measuring structure and the horizontal detection structure is used to detect the levelness of the measuring structure.

[0016] Because the magnetic base is magnetic, it is easy to place it on the end face of the container head, and the position of the magnetic base can be adjusted at any time according to the measurement point. At the same time, an adjustable support frame is set on the magnetic base, which can be adaptively adjusted according to the size of the part to be measured, so that the measuring structure corresponds to the part to be measured, and the level detection structure ensures the levelness of the measurement.

[0017] In use, first, attach the magnetic base to the end face of the container head. Adjust the height of the adjustable support frame, release the first clamping mechanism, move and rotate the measuring structure, and simultaneously observe the bubble on the horizontal detection structure. After adjusting the measuring structure to an absolutely horizontal state, lock the first clamping mechanism. At this point, the scale of the measuring structure provides a precise horizontal reference. Then, move the magnetic base to different measuring points on the end face of the container head to be measured. Since the height of the adjustable support frame and the horizontal orientation of the measuring structure are fixed, simply read the scale value corresponding to the position on the end face of the container head on the measuring structure. This reading is the height of the measuring point relative to the initial reference surface, and can be calculated. By measuring multiple points, the flatness, parallelism or inclination, and perpendicularity of the end face of the container head can be calculated.

[0018] This auxiliary device for measuring the distance between the end faces of container heads integrates magnetic fixation, horizontal calibration, and length measurement functions, offering the following advantages: 1. Unified benchmark and high accuracy: A stable and reliable horizontal benchmark is established through a single leveling step, avoiding benchmark non-parallelism errors caused by multiple measurements and significantly improving measurement accuracy. 2. Simple operation and high efficiency: Operated by a single person, the magnetic adsorption fixation is quick and easy, and readings can be taken directly after moving the device, greatly improving testing efficiency. 3. Strong adaptability: The magnetic base can adhere to any ferromagnetic metal surface, and the height of the adjustable support frame and the direction of the measuring structure are adjustable, making it suitable for measuring container heads of different sizes and positions. 4. Versatile functions: It can measure single-point distances and also comprehensively evaluate the overall form and position tolerances of the end faces, such as flatness and perpendicularity, through multi-point measurements.

[0019] 2. The auxiliary device for measuring the distance between the end faces of a container cap provided by this utility model includes an adjustable support frame comprising a first support rod and a second support rod. The first support rod is perpendicular to the center of the magnetic base, and the second support rod is rotatably connected to the first support rod. A rotating shaft is provided on both the first and second support rods, allowing the second support rod to rotate relative to the first support rod via the rotating shaft. By ensuring the first support rod is perpendicular to the magnetic base, the first support rod and the magnetic base are kept in a perpendicular state, preventing any offset. The position of the second support rod is then adjusted according to the position of the first support rod, thereby adjusting the position and levelness of the measuring structure.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this disclosure. Therefore, the drawings and description are to be considered exemplary in nature and not restrictive.

[0025] The preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] Please see Figure 1 As shown, this utility model provides an auxiliary device for measuring the distance between the end faces of a container cap, comprising: a magnetic base 1 disposed on the end face 2 of the container cap, wherein an adjustable support frame 3 is provided on the magnetic base 1 and the adjustable support frame 3 is rotatably connected to the magnetic base 1; a measuring structure 4 disposed on the magnetic base 1 via a first clamping mechanism 5, and a horizontal detection structure 6 is provided on the measuring structure 4, wherein the horizontal detection structure 6 is slidably connected to the measuring structure 4 and the horizontal detection structure 6 is used to detect the horizontality of the measuring structure 4.

[0027] Because the magnetic base 1 is magnetic, it is easy to place the magnetic base 1 on the end face 2 of the container head, and the position of the magnetic base 1 can be adjusted at any time according to the measurement point. At the same time, an adjustable support frame 3 is provided on the magnetic base 1, which can be adaptively adjusted according to the size of the container head, so that the measuring structure 4 corresponds to the end face 2 of the container head, and the horizontal detection structure 6 is used to ensure the levelness of the measurement.

[0028] In use, firstly, the magnetic base 1 is attached and fixed to the end face 2 of the container head. The height of the adjustable support frame 3 is adjusted, and the first clamping mechanism 5 is released to move and rotate the measuring structure 4. Simultaneously, the bubble in the horizontal detection structure 6 is observed. After the measuring structure 4 is adjusted to an absolutely horizontal state, the first clamping mechanism 5 is locked. At this point, the scale of the measuring structure 4 provides a precise horizontal reference. Then, the magnetic base 1 is moved to different measuring points on the end face 2 of the container head to be measured. Since the height of the adjustable support frame 3 and the horizontal orientation of the measuring structure 4 are fixed, the scale value corresponding to the position of the measuring structure 4 on the end face 2 of the container head is directly read. This reading is the height of the measuring point relative to the initial reference surface, and calculations can be performed. By measuring multiple points, the flatness, parallelism or inclination with the reference surface, and perpendicularity of the end face 2 of the container head can be calculated.

[0029] This auxiliary device for measuring the distance between the end faces of container heads integrates magnetic fixation, horizontal calibration, and length measurement functions, offering the following advantages: 1. Unified benchmark and high accuracy: A stable and reliable horizontal benchmark is established through a single leveling step, avoiding benchmark non-parallelism errors caused by multiple measurements and significantly improving measurement accuracy. 2. Simple operation and high efficiency: Operated by a single person, the magnetic adsorption fixation is quick and easy, and readings can be taken directly after moving the device, greatly improving detection efficiency. 3. Strong adaptability: The magnetic base 1 can be adsorbed onto any ferromagnetic metal surface, and the height of the adjustable support frame 3 and the direction of the measuring structure 4 are adjustable, making it suitable for measuring container heads of different sizes and positions. 4. Versatile functions: It can measure single-point distances and also comprehensively evaluate the overall form and position tolerances of the end faces, such as flatness and perpendicularity, through multi-point measurements.

[0030] The magnetic base 1 is a permanent magnet magnetic base or an electromagnetic magnetic base. The bottom surface of the magnetic base 1 is a flat adsorption surface, which can be firmly adsorbed onto the end face 2 of the container head or other metal reference surfaces.

[0031] In this embodiment, the adjustable support frame 3 includes a first support rod 31 and a second support rod 32. The first support rod 31 is perpendicular to the center of the magnetic base 1, and the second support rod 32 is rotatably connected to the first support rod 31.

[0032] The first support rod 31 and the second support rod 32 are equipped with a rotating shaft, allowing the second support rod 32 to rotate relative to the first support rod 31. By ensuring that the first support rod 31 is perpendicular to the magnetic base 1, the first support rod 31 and the magnetic base 1 are kept in a perpendicular position, preventing any misalignment. Then, the position of the second support rod 32 is adjusted based on the position of the first support rod 31, thereby adjusting the position and levelness of the measuring structure 4.

[0033] In this embodiment, the first support rod 31 and the second support rod 32 are made of telescopic rod structure, or they can be made of multiple rod segments connected together. The multiple rod segments are fixed by screws, thereby adjusting the height of the measuring structure 4 set on the adjustable support frame 3.

[0034] There are two first clamping mechanisms 5, which are symmetrically arranged in the middle of the measuring structure 4.

[0035] In this embodiment, there are two horizontal detection structures 6, which are respectively located on the top and side wall of the measuring structure 4. The horizontality of the measuring structure 4 can be detected from the top and side wall respectively, ensuring that the measuring structure 4 is perpendicular to the bottom surface of the magnetic base 1, thus ensuring the accuracy of the measurement.

[0036] The horizontal detection structure 6 is mounted on the measuring structure 4 via the second clamping mechanism 7. Since there are two horizontal detection structures 6, there are also two second clamping mechanisms 7.

[0037] Two second clamping mechanisms stably fix the horizontal detection structure 6 to the measuring structure 4, thereby ensuring the installation stability of the horizontal detection structure 6. Specifically, the first clamping mechanism 5 and the second clamping mechanism 7 are both universal locking clamps, such as universal clamps locked with wing nuts or quick-locking clamps with knurled knobs.

[0038] Since the measuring structure 4 is slidably connected to the adjustable support frame 3 and fixed by the first clamping mechanism 5, and the horizontal detection structure 6 is slidably connected to the measuring structure 4 and fixed by the second clamping mechanism 7, this sliding connection can effectively adjust the position of the measuring structure 4 relative to the adjustable support frame 3 and the position of the horizontal detection structure 6 relative to the measuring structure 4.

[0039] In this embodiment, the measuring structure 4 is a steel ruler with clear graduations; the detection structure is a leveling instrument.

[0040] The auxiliary device for measuring the distance between the end faces of a container head is operated as follows: 1. Establishing a reference: Place the auxiliary device on the leveled and calibrated reference end face of the cylinder, turn on the switch of the magnetic base 1 (if it is electromagnetic) or place it directly (if it is permanent magnet) to make the magnetic base 1 firmly adsorbed; 2. Leveling Auxiliary Device: Roughly adjust the height of the first support rod 31, loosen the first clamping mechanism 5, move and rotate the measuring structure 4 up and down, and observe the bubble on the horizontal detection structure 6. When the bubble is in the center position, tighten the first clamping mechanism 5 to lock the measuring structure 4 in a precise horizontal position. At this time, the initial reading of the measuring structure 4 on the reference plane can be recorded (usually set to 0). 3. Perform the measurement: Remove the magnetic base 1 from the reference surface and move it to the point to be measured on the end face 2 of the container head. Since the horizontal attitude of the measuring structure 4 has been locked, its height reference remains unchanged. Directly read the scale value corresponding to the measuring point position on the upper edge of the measuring structure 4; this value is the height difference between the measuring point and the initial reference surface. 4. Multi-point measurement and calculation: Repeat step 3, and uniformly select multiple measuring points on the circumference of the container head end face 2 to measure and record the data. By analyzing these height difference data, the overall flatness of the container head end face 2, the parallelism with the reference cylinder, or the perpendicularity deviation after assembly can be calculated.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
