Description

Technical Field

[0001] This utility model mainly relates to the field of thermostat technology, specifically a thermostat claw strength verification tooling. Background Technology

[0002] As an important component of the engine cooling system, the reliability of the thermostat directly affects the engine's performance and lifespan.

[0003] As a key component of the thermostat, the catch is responsible for transmitting the thrust generated by the expansion of paraffin wax to control the opening and closing of the valve. If the catch is not strong enough, it may deform or break under stress, causing the valve to malfunction and affecting the engine's cooling effect. Therefore, verifying the strength of the catch is an important measure to ensure the reliability of the thermostat. If the thermostat catch is not strong enough, it may suddenly break under excessive stress during vehicle operation, causing the coolant to fail to circulate properly, the engine to overheat, and in severe cases, even engine failure or traffic accidents.

[0004] In the tooling design of single-wax-encased thermostats, the structure and configuration of the tooling may focus on the overall assembly and fixation of the thermostat, while lacking specific consideration for the measurement of hook strength. In the existing technology, thermostat hook strength testing mostly relies on general pressure tooling, which cannot accurately simulate the dynamic stress state of the hook under the expansion thrust of paraffin wax, resulting in a large deviation between the test results and the actual working conditions. In addition, traditional tooling has a complex structure, is inconvenient to disassemble, and has low testing efficiency. Therefore, when facing test scenarios that require evaluation of hook strength, this traditional tooling design is inadequate. Therefore, a thermostat hook strength verification tooling is proposed. Utility Model Content

The verification fixture includes a test block for engaging the hooks and a cylinder for transmitting pressure to the test block within the thermostat mounting base. The test block is an independent component, and both ends of the test block are formed with engaging portions adapted to the hooks.

[0008] Preferably, the mounting base has a round-headed rod inside, and the test card block has a round-headed rod through groove for use with the round-headed rod.

[0009] Preferably, one end of the round-headed rod is connected to a connector fixedly installed inside the mounting base, and the cylinder body is provided with a movable through groove for use with the connector.

[0010] Preferably, the locking part engages with the locking block positioning groove opened on the inner side of the hook claw, the locking block positioning groove is a single-sided opening structure, and the two sets of locking block positioning grooves are arranged opposite to each other.

[0011] Preferably, the bottom of the mounting base is injection molded with two sets of hooks.

[0026] Please refer to the appendix carefully. Figure 1-4 A thermostat claw strength verification fixture, comprising a test block 3 and a cylinder 4.

[0027] The thermostat includes a mounting base 1, with two sets of hooks 2 at the bottom of the mounting base 1. The hooks 2 cooperate with a test block 3 for testing, and the test block 3 is an independent component. Both ends of the test block 3 are formed with snap-fit ​​parts 31 adapted to the hooks 2. Both ends of the mounting base 1 are open, and the pressure of the press is transmitted to the test block 3 through the cylinder 4 placed inside the mounting base 1, thereby testing the strength of the hooks 2 through the test block 3.

[0028] In this embodiment, as Figure 2 As shown, the snap-fit ​​part 31 engages with the snap-fit ​​positioning groove 201 opened on the inner side of the hook claw 2. The snap-fit ​​positioning groove 201 has a single-sided opening structure, and the two sets of snap-fit ​​positioning grooves 201 are arranged opposite to each other on the open sides.

[0029] With the above structure, the single-sided opening structure of the card block positioning groove 201 allows the test card block 3 to be easily inserted into the hook 2 by rotation. The cooperation design between the card block 31 and the card block positioning groove 201 not only simplifies the installation process, but also ensures that the test card block 3 can be accurately and quickly positioned in the predetermined position, improving the convenience and efficiency of operation.

[0030] In this embodiment, as Figure 1-3 As shown, the diameter of the cylinder 4 should be slightly smaller than the width inside the mounting base 1 to ensure that the cylinder 4 can be smoothly placed into the mounting base 1, while avoiding excessive gaps that could lead to unstable pressure transmission. Considering that the cylinder 4 needs to contact the top of the test card block 3, its diameter should be large enough to ensure sufficient contact area, thereby ensuring uniform pressure transmission. The length of the cylinder 4 should be long enough to ensure that its bottom can fully contact the top of the test card block 3, thereby effectively transmitting pressure. At the same time, the length of the cylinder 4 should not be too long to avoid unnecessary interference inside the mounting base 1 or affecting the normal operation of other components. The diameter of the cylinder 4 is 24mm and the length of the cylinder 4 is 85mm.

[0031] The above structure facilitates the transmission of pressure from the press and also promotes the integration and docking of the tooling with other testing equipment, improving the flexibility and compatibility of the test. The press pressure is transmitted to the test block 3 through the cylinder 4 placed inside the mounting base 1. This design ensures accurate and efficient pressure transmission and avoids test errors caused by pressure loss or uneven transmission. The test block 3 directly performs strength testing on the hook 2. This direct action method can more realistically simulate the force situation of the hook 2 in actual work, thereby improving the accuracy and reliability of the test.

[0032] In this embodiment, as Figure 1-2 and Figure 4 As shown, the test block 3 is an independent component, and the test block 3 is manually placed in the block positioning slot 201 opened by the hook 2.

[0033] With the above structure, the test card block 3, as an independent component, can be installed and disassembled separately, and can be replaced or adjusted according to different testing needs without replacing the entire tooling, thus improving the flexibility and adaptability of the test.

[0034] In this embodiment, as Figure 3 and Figure 4 As shown, the mounting base 1 is provided with a round-headed rod 5 inside, and the test card block 3 is provided with a round-headed rod through groove for cooperating with the round-headed rod 5. One end of the round-headed rod 5 is connected to a connector fixedly installed inside the mounting base 1, and the cylinder 4 is provided with a movable through groove for cooperating with the connector.

[0035] Through the above structure, the round-headed rod 5 guides the rotation of the test block 3 through the round-headed rod through slot on the test block 3. Due to the guiding effect of the round-headed rod 5, it is more convenient for the test block 3 to engage with the block positioning slot 201.

[0036] In this embodiment, as Figure 3 and Figure 4As shown, the cylinder 4 is located inside the mounting base 1 and does not contact the interior of the mounting base 1. The bottom of the cylinder 4 is in contact with the top of the test card block 3, and the cylinder 4 has an open structure at one end.

[0037] With the above structure, the bottom of the cylinder 4 is in direct contact with the top of the test block 3, ensuring that the pressure applied by the press can be accurately and stably transmitted to the test block 3, thereby conducting a strength test on the hook 2. The cylinder 4 does not contact the interior of the mounting base 1, reducing energy loss during pressure transmission and improving the accuracy of the test. The bottom of the cylinder 4 is designed as a symmetrical plane, and the machining accuracy of the contact surface with the top of the test block 3 is ±0.05mm, ensuring that the pressure is evenly distributed to the two sets of hooks 2.

[0038] The specific operating procedure of this utility model is as follows: First, the round-headed rod 5 passes through the test block 3 to guide the rotation of the test block 3. Then, the test block 3 is manually rotated to engage with the positioning groove 201 on the inner side of the hook 2. After the above operation is completed, the cylinder 4 is placed inside the mounting base 1 at a suitable angle. Then, the press is started, and the pressure of the press is applied to the top of the cylinder 4, thereby being transmitted to the test block 3 through the cylinder 4. The bottom of the cylinder 4 is in direct contact with the top of the test block 3 to ensure the accuracy and stability of the pressure transmission. Finally, the test block 3 performs a strength test on the hook 2 under the received pressure to verify the strength performance of the hook 2 under simulated actual stress conditions.

[0039] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
