Description

Technical Field

[0001] This utility model relates to the field of thrust testing technology, specifically to a position-adjustable thrust testing fixture. Background Technology

[0002] In numerous industrial production and scientific research fields, precise thrust testing of various pipe fittings is a crucial task. Thrust testing can obtain mechanical performance data of pipe fittings under thrust, which is of key significance for evaluating the quality and reliability of pipe fittings and determining their applicability in practical applications. For example, in the aerospace field, pipe fittings need to withstand extremely complex mechanical environments, and accurate thrust test data helps ensure the safe operation of aircraft. In the automotive manufacturing industry, the thrust performance of pipe fittings directly affects the power transmission and overall structural stability of vehicles. In the field of mechanical engineering, the thrust-bearing capacity of pipe fittings in various hydraulic and pneumatic systems is related to the normal operation of the entire system.

[0003] During the testing process, the support and fixing methods for the test pipes are not ideal. Some fixtures cannot provide stable and uniform support for the test pipes. When subjected to thrust, the pipes are prone to shaking or displacement, which affects the accuracy and reliability of the test results. Especially when conducting high-precision thrust tests, even a small shaking can lead to a large deviation in the test data, which cannot truly reflect the actual performance of the pipes. Therefore, we need to propose a position-adjustable thrust testing fixture. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution:

[0025] An adjustable thrust testing fixture includes a base plate 1;

[0026] Assembly component 2 is installed on the top of one end of the base plate 1;

[0027] Test fitting 3 is installed on assembly component 2 by bolts;

[0028] Auxiliary support component 4 is movably set on the surface of base plate 1 and is used to provide auxiliary support for the test tube 3 during thrust testing.

[0029] The thrust test assembly 5 is installed on the surface of the base plate 1 away from the assembly assembly 2, and is used to perform thrust tests on the fixed test tube 3.

[0030] The base plate 1, as the basic load-bearing component of the entire fixture, is made of high-strength alloy material to ensure the overall structural stability of the fixture and to withstand various forces during the testing process without deformation. The assembly component 2, auxiliary support component 4, and thrust testing component 5 are all installed on the base plate 1, forming a unified whole. This ensures the relative positional accuracy between the components and improves the accuracy of the test. The movable design of the auxiliary support component 4 allows it to be flexibly adjusted on the base plate 1 according to the length of the test tube 3 and the testing requirements, providing support for different parts of the test tube 3. This effectively prevents the test tube 3 from bending or shaking under the thrust, ensuring the reliability of the test results.

[0031] In an optional embodiment: the thrust test assembly 5 includes a fine-tuning displacement platform 51, which is bolted to the top surface of the base plate 1. A mounting block 52 is fixedly mounted on the top surface of the fine-tuning displacement platform 51 by bolts. A force sensor 53 is fixedly mounted on one side of the mounting block 52 by bolts, and one side of the force sensor 53 is bolted to one end of the test tube 3.

[0032] It should be noted that the fine-tuning displacement platform 51 can achieve precise position adjustment. Through fine-tuning, the force sensor 53 can be precisely connected with the test tube 3, ensuring that the position of the thrust application is accurate and improving the test accuracy. The mounting block 52 provides a stable connection structure for the fine-tuning displacement platform 51 and the force sensor 53, making the connection between the two firm and preventing relative displacement during the test, thus ensuring stable force transmission. The force sensor 53 is directly connected to the end of the test tube 3, which can directly and accurately detect the magnitude of the thrust applied to the test tube 3. The force sensor 53 is electrically connected to the control system, providing real-time feedback of test data and providing a reliable basis for the test results. The bolt connection method facilitates the installation, disassembly, and maintenance of each component, while ensuring the tightness of the connection.

[0033] Force sensor 53: HBM U9B series force sensors can be selected. This series of sensors has high accuracy, wide measurement range, good stability, and is suitable for various thrust testing scenarios.

[0034] In an optional embodiment: a number of sets of threaded adjustment holes 6 are symmetrically provided on one end of the base plate 1 for bolting and fixing the fine-tuning displacement platform 51 with bolts.

[0035] It should be noted that the setting of several sets of threaded adjustment holes 6 allows the installation position of the fine-tuning displacement platform 51 on the base plate 1 to be adjusted to meet the thrust testing requirements of test pipe fittings 3 of different lengths. The symmetrical design ensures that the force on the fine-tuning displacement platform 51 is uniform when it is fixed, avoiding the impact on test accuracy due to unstable fixing. The threaded adjustment holes 6, in conjunction with the bolts, can firmly fix the fine-tuning displacement platform 51 on the base plate 1, preventing displacement due to thrust during the test and ensuring the stability of the test.

[0036] In an optional embodiment: the assembly component 2 includes a mounting plate 21, on which a bearing 22 is embedded, and a fixing tube 23 is fixedly inserted into the inner ring of the bearing 22. One end of the test tube 3 is bolted to one end of the fixing tube 23.

[0037] It should be noted that the mounting plate 21 provides a stable mounting base for the entire assembly 2, enabling it to be firmly installed on the base plate 1. The bearing 22 allows the fixed tube 23 to rotate at a certain angle. During the test, if the test tube 3 is subjected to thrust and a slight angular deviation occurs, the bearing 22 can play a certain buffering role, preventing damage to the test tube 3 or the assembly 2 due to rigid connection. The fixed tube 23 and the test tube 3 are connected by bolts, which is reliable and facilitates the replacement of the test tube 3, improving the versatility of the tooling.

[0038] In an optional embodiment: the auxiliary support assembly 4 includes a support block 41, a bearing seat 42 is detachably mounted on the top of the support block 41, a linear bearing 43 is fixedly mounted inside the bearing seat 42, and the linear bearing 43 is sleeved on the outer wall of the test tube 3.

[0039] It should be noted that the support block 41 provides stable support for the bearing seat 42, ensuring the overall height of the auxiliary support assembly 4, so that the linear bearing 43 can be accurately fitted onto the test tube 3. The linear bearing 43 is fitted onto the outer wall of the test tube 3. When the test tube 3 is subjected to thrust and moves axially, the linear bearing 43 can reduce the friction between the test tube 3 and the support structure, making the movement of the test tube 3 smoother, avoiding the interference of friction on the thrust test results, and ensuring the accuracy of the test.

[0040] In an optional embodiment: the auxiliary support assembly 4 further includes four sets of hexagon socket screws 44, and two sets of countersunk holes adapted to the hexagon socket screws 44 are provided on both sides of the bearing seat 42. A blind hole corresponding to the countersunk hole is provided on the top of the support block 41, and one end of the hexagon socket screw 44 passes through the countersunk hole and is threaded into the inside of the blind hole.

[0041] It should be noted that four sets of hex socket screws 44 are fixed to the bearing housing 42 from both sides, making the connection between the bearing housing 42 and the support block 41 more secure and reliable. No relative displacement will occur during the test, ensuring the stability of the linear bearing 43 supporting the test tube 3. The countersunk hole design allows the head of the hex socket screw 44 to be embedded inside the bearing housing 42, preventing the screw head from protruding and affecting the normal operation of other components, while also making the tooling look neater.

[0042] In an alternative embodiment, the fixed tube 23, the linear bearing 43, and the force sensor 53 are arranged coaxially.

[0043] It should be noted that the coaxial arrangement ensures that the thrust can be transmitted along the axis of the test tube 3, avoiding additional torque caused by misalignment and preventing the test tube 3 from being subjected to unnecessary torque that could affect the test results or damage the test tube 3. At the same time, the coaxial arrangement makes force transmission smoother, reduces energy loss, improves the accuracy of the data detected by the force sensor 53, ensures the precision and reliability of the test, and ensures that the test results truly reflect the performance of the test tube 3 under axial thrust.

[0044] Working principle: When using this utility model, the auxiliary support assembly 4 is moved to the side closer to the thrust test assembly 5. One end of the test tube 3 passes through the linear bearing 43 and is fixed to the force sensor 53 by screws. The other end is fixed to the fixing tube 23 in the assembly assembly 2 by bolts. According to the length of the test tube 3, the position of the auxiliary support assembly 4 on the base plate 1 is moved so that the linear bearing 43 provides stable support for the test tube 3 and prevents it from shaking or shifting during the thrust test.

[0045] Rotating the micrometer of the fine-tuning displacement platform 51 slowly and precisely pushes the force sensor 53 on the mounting block 52 to apply a thrust to the test tube 3 along a preset path. The fine-tuning displacement platform 51 has high-precision displacement control capabilities, enabling fine adjustment of the thrust magnitude to meet different testing requirements. During the application of the thrust, the thrust force on the test tube 3 is measured in real time by the force sensor 53. The force sensor 53 converts the thrust signal into an electrical signal and transmits it to the external control system. The data acquisition module and analysis module in the control system process and analyze the electrical signal, display the thrust magnitude and changes in real time, and record the test data for subsequent evaluation of the mechanical properties of the test tube.

[0046] Throughout the thrust test, the control system continuously records the thrust change curve over time and other relevant parameters. After the test is completed, the operator can analyze the mechanical response of the test pipe 3 under different thrusts based on the recorded data to determine whether it meets the design requirements and usage standards.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
