Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tooling for detecting the size of a wedge ring window. Background Technology

[0002] In shell and cylindrical section connections, wedge ring connections are a widely used method that ensures the smoothness of the outer surface of the connection area and facilitates assembly and disassembly. In wedge ring connections, the wedge ring window size, wedge ring stiffness, and the gap between the wedge ring and the mounting groove play a crucial role in the connection strength.

[0003] The dimensional accuracy requirements for wedge ring windows are typically high, but traditional inspection methods may be limited by the precision of the measuring tools, making it difficult to meet these requirements. Some inspection methods may rely on manual operation, such as using vernier calipers or outside micrometers to measure the relevant dimensions of the wedge ring. For mass production, this method is time-consuming and labor-intensive, making it difficult to meet the needs of efficient production. Furthermore, structures measured using standard molds may have inaccurate measurements due to the presence of chamfers or other structural features during manufacturing. Therefore, this application anticipates a tooling method for inspecting the dimensions of wedge ring windows that can improve inspection efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of low efficiency and poor accuracy in wedge ring window detection in the existing technology, this utility model provides a tooling for wedge ring window size detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tooling for detecting the size of a wedge ring window includes a base, the base being a boss structure, with a stop block detachably connected to the shoulder of the boss, and two side walls at the large end of the boss being provided with wedge-shaped grooves, with a wedge block detachably connected to the wedge grooves, and an arc-shaped abutment surface provided circumferentially on the side wall at the large end of the boss between the stop block and the wedge block.

[0007] The locking structure formed by the stop block and wedge block at one end of the base constitutes a through end, and the locking structure formed by the stop block and wedge block at the other end constitutes a stop end.

[0008] Furthermore, the structure of the arc-shaped contact surface is adapted to the structure of the wedge ring window to be tested.

[0009] Furthermore, the structural dimensions formed by the stop block and wedge block at the through end are the minimum allowable dimensions of the wedge ring window size to be measured, and the structural dimensions formed by the stop block and wedge block at the stop end are the maximum allowable dimensions of the wedge ring window size to be measured.

[0010] Furthermore, the inclined surfaces of the two wedges located at the through end and the stop end have the same inclination angle, and the vertical lengths of the two arc-shaped contact surfaces located at the through end and the stop end are different.

[0011] Furthermore, the inclination angle of the inclined surface of the wedge block and the wedge-shaped groove is consistent with the inclination angle of the wedge ring window to be tested.

[0012] Furthermore, both the stop block and the wedge block are provided with T-shaped threaded grooves, which are detachably connected to the base by clamping screws.

[0013] Furthermore, the smaller end of the base is a cylindrical handheld part.

[0014] The beneficial effects of this utility model are:

[0015] This application provides a fixture for measuring the size of a wedge ring window, including a base with a boss structure. A stop block is detachably connected to the shoulder of the boss. Two sidewalls at the large end of the boss are provided with wedge-shaped grooves, and a wedge block is detachably connected within each groove. An arc-shaped contact surface is provided circumferentially on the sidewall of the large end of the boss between the stop block and the wedge block. The locking structure formed by the stop block and the wedge block at one end of the base constitutes a through end, and the locking structure formed by the stop block and the wedge block at the other end constitutes a stop end. This application eliminates the excessive curvature formed by integral molding by detaching the connected stop block and wedge block, thereby improving the measurement accuracy of the wedge ring window size. Simultaneously, by providing a through end and a stop end at both ends of the base, it is possible to directly measure whether the size of the wedge ring window to be measured is within a preset range, thus greatly improving the measurement efficiency.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] This disclosure provides a tooling for detecting the size of a wedge ring window, which improves the efficiency and accuracy of wedge ring window size detection.

[0025] Figure 1 A cross-sectional view of a tooling for dimensional detection according to an embodiment of this disclosure is shown, such as... Figure 1 As shown, it includes a base 1, which is a boss structure. A stop block 2 is detachably connected to the shoulder of the boss. Two side walls of the large end of the boss are provided with wedge-shaped grooves 5. A wedge block 3 is detachably connected to the wedge groove 5. An arc-shaped abutment surface 6 is provided circumferentially on the side wall of the large end of the boss between the stop block 2 and the wedge block 3.

[0026] The locking structure formed by the stop block 2 and the wedge block 3 at one end of the base 1 constitutes a through end, and the locking structure formed by the stop block 2 and the wedge block 3 at the other end constitutes a stop end.

[0027] Figure 2 and Figure 3 Cross-sectional and top views of the base 1 according to an embodiment of this disclosure are shown respectively, as follows: Figure 1 As shown, the inclined surface formed by the wedge-shaped groove 5 and the wedge block 3 of the base 1, as well as the abutment surface formed by the arc-shaped abutment surface 6 and the stop block 2, do not produce curved transition edges. Compared with the integrally formed measurement structure, which mostly has chamfers and other curved surfaces in the transition area, this solution can improve the detection accuracy.

[0028] In this embodiment of the present disclosure, the structure of the arc-shaped contact surface 6 is adapted to the structure of the wedge ring window to be tested. Specifically, the arc-shaped contact surface 6 is used to contact the curved surface of the wedge ring window to be tested. At this time, the curved surface of the wedge ring window to be tested serves as a reference surface for determining the dimensions of its plane and inclined surfaces.

[0029] In this embodiment, the structural dimensions formed by the stop block 2 and wedge block 3 at the through end are the minimum permissible dimensions of the wedge ring window to be tested, and the structural dimensions formed by the stop block 2 and wedge block 3 at the stop end are the maximum permissible dimensions of the wedge ring window to be tested. It should be noted that the size difference between the through end and the stop end constitutes the size error threshold range of the wedge ring window to be tested. During testing, if the size of the wedge ring window to be tested is smaller than the size of the stop end, the through end must also be tested.

[0030] Specifically, the inclined surfaces of the two wedges 3 located at the through end and the stop end have the same inclination angle, and the vertical lengths of the two arc-shaped abutment surfaces 6 located at the through end and the stop end are different. That is, in this embodiment, more attention is paid to whether the thickness of the end of the wedge ring window and the inclined surface is within a preset range. Therefore, in this embodiment, the inclination angle of the inclined surfaces of the wedges 3 and the wedge-shaped groove 5 is consistent with the inclination angle of the wedge ring window to be tested. In other embodiments, if more attention is paid to the inclination angle of the inclined surface of the wedge ring window to be tested, the through end and the stop end should be set to have different inclination angles to determine whether their inclination angles are within a preset range.

[0031] Figure 4 and Figure 5 The front view and cross-sectional view of the wedge block 3 according to an embodiment of this disclosure are shown. Figure 6 A cross-sectional view of the stop block 2 according to an embodiment of this disclosure is shown in the figure. Both the stop block 2 and the wedge block 3 are provided with T-shaped threaded grooves. The T-shaped threaded grooves are detachably connected to the base 1 via clamping screws 4. Correspondingly, the base 1 also has threaded holes corresponding to the positions of the T-shaped threaded grooves for connecting the clamping screws 4. It should be noted that the length difference between the stop block 2 and the shoulder surface of the boss depends on the structure and size of the detection area of ​​the wedge ring window to be tested.

[0032] In this embodiment, the smaller end of the base 1 is a cylindrical handheld portion. Those skilled in the art can hold the base 1 to inspect the wedge ring window under test, achieving accurate measurement of the wedge ring groove thickness, and the operation is simple and reliable.

[0033] When in use, this utility model includes:

[0034] Hold the small end of the base 1 and press the inclined surface of the wedge block 3 against the inclined surface of the wedge ring window to be tested, and check whether the angle of the wedge ring window is within the preset range;

[0035] Then bring the curved surface of the wedge ring window to be tested close to the arc-shaped contact surface 6 and observe whether the curved surface can fit tightly with the arc-shaped contact surface 6;

[0036] When determining the thickness of the end and the bevel of the wedge ring window to be measured, if the through end can hold the wedge ring window but the stop end cannot, it indicates that the thickness of the wedge ring window is within the required dimensional tolerance range; if both the through end and the stop end can hold the wedge ring window, it indicates that the thickness of the wedge ring window is below the lower tolerance; if neither the through end nor the stop end can hold the wedge ring window, it indicates that the thickness of the wedge ring window is above the upper tolerance.
