Description

Technical Field

[0001] The utility model relates to the technical field of tooling structures, in particular to an anti-rotation joint tooling and detection equipment. Background Art

[0002] Solenoid valves are key actuators of modern automatic control systems. Different types of solenoid valves are required for operation and control in automobile engine systems, transmission systems, suspension systems, and body systems. Types of solenoid valves include VTS, DESC, and LFS for passenger car transmissions, air valves for commercial vehicle transmissions, and CDC solenoid valves for suspensions. Since solenoid valves are hydraulic or pneumatic control components, monitoring and measuring the pressure values ​​of their P, A, and T ports is an important indicator for evaluating the performance of solenoid valves. There are many types of solenoid valves. When testing, it is usually necessary to replace different fixtures to adapt to the corresponding solenoid valves. When replacing the fixtures, it is necessary to disassemble and assemble the force sensors that monitor the supply pressure and control pressure of the solenoid valves. Different types of solenoid valves require different pressures, and pressure sensors of different ranges also need to be replaced to match the measurement of the solenoid valves.

[0003] During the test of the solenoid valve, the pressure is up to 200 Bar, and the test environment temperature range is -40℃~150℃. Usually, a force sensor with high and low temperature resistance and an accuracy of 0.01kPa is selected. The size specifications of the sensors that can meet the requirements in the relevant technology are usually as follows Figure 1 As shown. Since the sensor harness is long and has a threaded interface, the root is often subjected to the rotation torque during the installation and rotation process, which can cause the harness to be damaged, short-circuited, and broken after a long period of time. Therefore, an anti-rotation connector tooling is urgently needed to prevent the sensor from damaging the harness by multiple rotations. Summary of the invention

[0032] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0033] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0034] Figure 1 A schematic diagram of a damaged sensor provided for related technology. Figure 1 As shown, in the related art, since the wiring harness of the sensor (for example, the kulite sensor) is long and has a threaded interface, the root is often subjected to a rotational torque during the installation and rotation process, which may cause the wiring harness to be damaged, short-circuited, and broken under long-term action.

[0035] Please refer to Figure 2-Figure 6 . The utility model provides an anti-rotation joint tool 100, which is used to achieve the matching of a test fixture and a sensor. The anti-rotation joint tool 100 includes a mating joint 10, an oil guide pipe 11 and a locking sleeve 12. The mating joint 10 is used to connect the test fixture. The oil guide pipe 11 is used to rotate itself to achieve a detachable connection with the sensor. The locking sleeve 12 is sleeved on the mating joint 10 and the oil guide pipe 11, and can be used to lock the relative position of the mating joint 10 and the oil guide pipe 11. Among them, the mating joint 10 is connected to the oil guide pipe 11, and the mating joint 10 and the oil guide pipe 11 have a guide channel that is fluidically connected to each other, and the two ends of the guide channel are respectively used to connect the test fixture and the sensor.

[0036] It is worth mentioning that the anti-rotation joint tooling 100 adopts a fluid-connected guide channel. Based on the principle that the pressure at each position in the cavity filled with the medium is equal, there is no need to directly twist the sensor. The purpose of tightening the sensor is achieved by rotating the oil guide tube 11. This can avoid directly twisting the sensor wiring harness during the sensor disassembly and assembly process, thereby avoiding damage or breakage of the sensor.

[0037] Please refer again Figure 4 and Figure 5 The locking sleeve 12 has a limiting slope 121, and the limiting slope 121 cooperates with the inner wall of the locking sleeve 12 to form a small-diameter opening 122 and a large-diameter opening 123. The oil guide pipe 11 is inserted into the small-diameter opening 122, and the outer surface of a part of the oil guide pipe 11 has a limiting block 113. When the mating joint 10 and the oil guide pipe 11 are in a locked state (i.e. Figure 4 In the state shown in the figure), the limiting block 113 and the limiting inclined surface 121 abut against each other.

[0038] It is worth noting that the limiting inclined surface 121 cooperates with the limiting block 113 of the oil guide tube 11 to achieve precise positioning and alignment, ensuring that the oil guide tube 11 is in the correct position when in the locked state, thereby improving assembly accuracy and assembly efficiency. In addition, when the fitting and the oil guide tube 11 are in the locked state, the limiting block 113 abuts against the limiting inclined surface 121, which can provide additional fixation and stability, preventing the oil guide tube 11 from accidentally moving or falling off during use, thereby enhancing overall reliability and safety.

[0039] In this embodiment, the limit block 113 is a wedge-shaped block structure, and the mating joint 10 has a clamping block 101 that cooperates with the limit block 113. When the mating joint 10 and the oil guide pipe 11 are in a locked state, the wedge block is embedded in the notch groove formed by the clamping block 101.

[0040] It is worth noting that the limit block 113 of the wedge-shaped block structure can play the role of guidance and installation at the same time. That is, when the mating joint 10 and the oil pipe 11 are in a locked state, the limit block 113 is embedded in the notch formed by the clamping block 101, which can provide better connection stability, thereby preventing accidental loosening or falling off. At the same time, the limit block 113 of this structure can also ensure good positioning and alignment, which helps to ensure that the oil pipe 11 is in an accurate position during installation, thereby improving the efficiency and speed of assembly. This structure can also withstand greater pressure and vibration, reducing the risk of loosening or wear, thereby extending the service life of the anti-rotation joint tooling 100.

[0041] In this embodiment, the locking sleeve 12 is threadably matched with the mating joint 10 . When the mating joint 10 and the oil guide pipe 11 are in a locked state, the oil guide pipe 11 is embedded in the mating joint 10 .

[0042] It is worth noting that the threaded locking sleeve 12 and the mating joint 10 are easy to operate and stable after mating. When the mating joint 10 and the oil guide pipe 11 are in a locked state, the oil guide pipe 11 is embedded in the mating joint 10 to further improve the structural stability of the structure after assembly.

[0043] Please refer again Figure 6 The oil guide pipe 11 is a boss structure, and the locking sleeve 12 is sleeved on the small diameter section 111 of the oil guide pipe 11. The large diameter section 112 of the oil guide pipe 11 has an internal thread (not shown in the figure). Through the internal thread, the oil guide pipe 11 can be detachably connected to the sensor.

[0044] It is worth noting that the internal thread inside the large diameter section 112 of the oil guide tube 11 can make the installation of the sensor simpler and more convenient. The sensor can be directly installed on the anti-rotation joint fixture 100 through the thread after rotating the oil guide tube 11, and it can be easily disassembled and replaced when necessary, thereby improving the flexibility of the fixture. In addition, through the internal thread connection, a tighter connection can be achieved between the sensor and the oil guide tube 11, reducing the risk of leakage, helping to ensure the normal operation of the sensor, and preventing liquid or gas from leaking at the connection part, thereby improving the overall reliability and safety.

[0045] At the same time, since the oil guide pipe 11 has a boss structure, the connection part can be made more compact, saving space. In some space-constrained application scenarios, it can effectively utilize the limited space and improve the design flexibility and efficiency of the tooling.

[0046] In this embodiment, the connection between the small diameter section 111 and the large diameter section 112 is arc-shaped. It can be understood that the arc transition can effectively reduce the stress concentration at the connection, making the oil guide tube 11 more stable and reliable during use. In addition, it can make the appearance of the oil guide tube 11 more smooth and reduce possible sharp edges or protruding parts. Depending on the specific implementation environment, other connections of the anti-rotation joint tooling 100 can also be processed with arc transitions.

[0047] Please refer again Figure 1 and Figure 2 The mating connector 10 comprises a mating head 102 for connecting to a test fixture, and an outer surface of the mating head 102 has an outer thread adapted to the test fixture.

[0048] In this embodiment, the mating connector 10 further includes a contact end 103 for sealing the test fixture. The diameter of the contact end 103 is larger than the diameter of the mating connector 102. A sealing ring is disposed on the contact end 103. Figure 2 As shown, the contact end 103 is provided with an annular groove 104, and the sealing ring is embedded in the annular groove 104. It can be understood that the installation and arrangement of the sealing ring can prevent the leakage of fluid or gas, thereby improving the overall safety of the tooling and the accuracy of measurement.

[0049] The assembly process of the anti-rotation joint tool 100 may be as follows:

[0050] During installation, first screw the mating joint 10 into the threaded hole of the test fixture, then connect the oil guide pipe 11 to the sensor, and finally tighten the locking sleeve 12 in the middle.

[0051] The assembly process is simple and easy to operate. Experiments have shown that the sensor wiring harness is intact after multiple disassembly and assembly, and the robustness is improved. At the same time, whether or not the tooling is used has no difference in the pressure value measured by the sensor, and has no effect on the test of hydraulic performance.

[0052] This embodiment also provides a detection device, including the above-mentioned anti-rotation joint tooling 100, having all its beneficial effects.
