Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange inspection technology, and in particular to an inclination detector with a positioning structure. Background Technology
[0002] Engine exhaust systems and turbochargers must withstand high temperatures and pulse pressures. The clamp flange, through its axial clamping action, generates radial contraction force, creating a 360° uniform seal between the flange face and the gasket. This effectively prevents high-temperature exhaust gas leakage, avoids turbine efficiency degradation, and is superior to traditional bolted flanges in terms of localized stress concentration. However, its beveled or conical surface is typically used to form a tight fit with the gasket or mating components. If the flange bevel dimensions are irregular at the manufacturing stage, it can lead to uneven pressure distribution during tightening, causing fuel, lubricating oil, or high-temperature gas leakage, directly affecting engine efficiency and safety. Currently, flange bevel inspection often uses coordinate measuring machines or laser scanning for full-dimensional measurement, which is time-consuming, expensive, and increases upfront costs. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides an inclination detector with a positioning structure, which solves the problem of high cost of existing flange inclination detectors.
[0004] According to the embodiments of this utility model, the following technical solution is adopted:
[0005] An inclination detector with a positioning structure includes:
[0006] The base and flange are mounted on the base;
[0007] Mounting bracket, the mounting bracket having a slidingly mounted gauge, the gauge's testing end abutting against the inclined surface of the flange; and
[0008] Two limit strips are located on the base and are used to limit the movement of the flange.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] In this solution, the base supports the flange, and with the cooperation of the limiting strip and the base, the flange can be positioned and installed with one click, allowing the measuring instrument to directly contact the inclined surface for reading. This saves a lot of time and improves efficiency in batch flange inspection operations. Compared with the traditional coordinate measuring machine (CMM) inspection steps, this solution automatically aligns the flange inspection datum through a mechanical positioning structure, requiring no professional operators and lowering the requirements. Moreover, when inspecting the flange, the flange located between the two limiting strips can be rotated, allowing the measuring instrument's inspection end to slide on the flange's inclined surface, making operation more convenient.
[0011] Preferably, it also includes an adjusting rod, which is rotatably located at the end of the base, and both ends of the adjusting rod are provided with threaded portions, which are respectively threadedly connected to two limiting strips.
[0012] Preferably, a limiting groove is provided at one end of the base near the adjusting rod, and two limiting blocks are slidably provided in the limiting groove, with the two limiting blocks respectively connected to two limiting strips.
[0013] Preferably, a knob is fixedly provided at the end of the adjusting rod.

[0015] Preferably, it also includes a positioning rod, which passes through the mounting bracket and has its end abutting against the flange.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0022] This utility model embodiment proposes an inclination detector with a positioning structure, including:
[0023] Base 1, flange 4 is installed on base 1;
[0024] Mounting bracket 2, with a sliding gauge 3, the measuring end of gauge 3 abutting against the inclined surface of flange 4; and
[0025] Two limit bars 5 are located on the base 1 and are used to limit the flange 4.
[0026] In the embodiments of this utility model, such as Figure 1As shown, the base 1 has a plate structure, and the two limiting strips 5 in the initial state are located on both sides of the base 1. When inspecting the flange 4, the flange 4 is placed directly on the base 1 with the inclined surface of the flange 4 facing upwards. In the selection of the measuring instrument 3, a dial indicator or a micrometer can be used according to the accuracy requirements. For example, taking the use of a dial indicator as an example, the installation and adjustment methods of the dial indicator are already conventional technical means. After the measuring instrument 3 is installed on the mounting bracket 2, the measuring instrument 3 is adjusted to be tilted so that the measuring end of the measuring instrument 3 is perpendicular to the inclined surface of the flange 4. At the same time, the height of the measuring instrument 3 is adjusted along the Z-axis so that the measuring end of the measuring instrument 3 is pressed against the inclined surface of the flange 4 and a reading is obtained. Meanwhile, after flange 4 is positioned on base 1, it will be limited by two limit strips 5 to prevent it from shifting to the left or right. Therefore, when inspecting flange 4, by rotating flange 4, all inclined surfaces of flange 4 are made to abut the inspection end of inspection gauge 3. During the rotation of flange 4, pay attention to the reading of inspection gauge 3 and observe whether the reading jumps and whether the jump range meets the processing tolerance. If it meets the tolerance, the product is qualified; if it does not meet the tolerance, the product is unqualified.
[0027] Based on the above scheme, in order to facilitate the adjustment of the two limit bars 5, such as Figure 1 As shown, it also includes an adjusting rod 6, which is rotatably mounted at the end of the base 1. Both ends of the adjusting rod 6 are provided with threaded portions 601, which are respectively threaded to two limiting strips 5. The threads 601 at both ends of the adjusting rod 6 are related in rotation direction, and the adjusting rod 6 can only rotate at the end of the base 1. Therefore, when the adjusting rod 6 rotates, the threaded portions 601 at both ends drive the corresponding limiting strips 5, causing the two limiting strips 5 to move closer or further apart. This can be applied to the inspection of flanges 4 of different diameters.
[0028] Furthermore, the end of the limiting strip 5 is equipped with a guide wheel 501, which rolls against the flange 4. In the inspection of flanges 4 of different sizes, by directly rotating the adjusting rod 6, the guide wheels 501 of the two limiting strips 5 can roll against the circumferential surface of the flange 4. The guide wheels 501 can reduce the friction when the flange 4 is rotated for inspection. At the same time, under the installation of the flange 4, it is always ensured that the axis of each dimension is at the same point on the base 1. That is, the distance between the two guide wheels 501 is the diameter of the flange 4. Only the Y-axis adjustment of the inspection gauge 3 is required.
[0029] To facilitate the adjustment of the limiting strip 5, a limiting groove 101 is provided at one end of the base 1 near the adjusting rod 6. Two limiting blocks 502 are slidably provided in the limiting groove 101. The two limiting blocks 502 are respectively connected to the two limiting strips 5. The limiting blocks 502 can automatically limit the limiting strips 5, so that the limiting strips 5 can only move along the length direction of the limiting groove 101. When adjusting the limiting strips 5 laterally, there is no need to manually press them or perform other operations, which is convenient to use.
[0030] Specifically, a knob 602 is fixedly provided at the end of the adjusting rod 6, which can be used to quickly operate the adjusting rod 6 without the need for other auxiliary tools.
[0031] Based on the above scheme, in order to further improve the accurate positioning of flange 4 before inspection, such as Figure 2 As shown, it also includes a positioning rod 7, which passes through the mounting bracket 2 and its end abuts against the flange 4. The end of the positioning rod 7 always corresponds to the detection end of the gauge 3, and the end of the positioning rod 7 forms a three-point positioning with the guide wheels 501 of the two limit strips 5. Regardless of the size of the flange 4 being tested, when the distance between the two guide wheels 501 is exactly the diameter of the flange 4, the end of the positioning rod 7 just abuts against the flange 4. The flange 4 is limited to the left and right by the two limit strips 5, and the flange 4 is limited to the front and back by the palm and the positioning rod 7, ensuring that there is no deviation when the flange 4 is rotated for testing, thus indirectly ensuring the accuracy of the gauge 3 when testing the flange 4.
[0032] Meanwhile, the end of the positioning rod 7 is provided with a positioning wheel 701, which rolls against the flange 4; this allows the end of the positioning rod 7 to roll against the side of the flange 4, which not only avoids scratching the side of the flange 4, but also facilitates rotation detection of the flange 4.
[0033] Specifically, the positioning rod 7 is installed on the mounting bracket 2 by passing it through. Although it can achieve self-fixation under friction operation, in order to further ensure its stability after adjustment, such as Figure 1 As shown, the mounting bracket 2 is threadedly connected to a pressing screw 702. The end of the pressing screw 702 abuts against the side of the positioning rod 7. After adjusting the positioning rod 7 back and forth so that the positioning wheel 701 corresponds to the detection end of the gauge 3, the pressing screw 702 is rotated so that the end of the pressing screw 702 abuts against the side of the positioning rod 7. The positioning rod 7 is fixed by friction to prevent displacement caused by the pressure of the flange 4.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
