[0023] In order to make the purpose, technical scheme and advantage of the present application more clear, the present application is further explained in detail below in combination with the drawings and examples. It should be understood that the specific examples described here are only used to explain the present application, and are not used to limit the present application.

[0024] With reference to Figures 1 to 4 The utility model discloses a kind of pressure-withstand test mechanism, including fixed frame 1, test structure and drive structure, fixed frame 1 is formed with test surface 11 and drive surface 12, and first opening 13 and second opening 14 are separately provided on the surface of fixed frame 1;Test structure includes the first test piece 2 and second test piece 3 of being set to test surface 11, and two are respectively adjacent first opening 13 and second opening 14 setting, the side of first test piece 2 towards second test piece 3 is provided with multiple contact sheets 21, and the side of second test piece 3 towards first test piece 2 is provided with multiple contact pins 31;Drive structure includes the first drive piece 41 and second drive piece 42 of being set to drive surface 12, and two are respectively driven and connect in first test piece 2 and second test piece 3, to drive first test piece 2 and second test piece 3 mutually close and clamping workpiece are tested.

[0025] The fixed frame 1 is the support structure of the whole mechanism, responsible for supporting and fixing other parts. The test surface 11 and the drive surface 12 are two surfaces of the fixed frame 1, wherein the test surface 11 is used to install the test structure, and the drive surface 12 is used to install the drive structure. The fixed frame 1 has two openings, namely the first opening 13 and the second opening 14, which are used to connect the drive structure and the test structure to provide power to the test structure to make reciprocating movement. The test structure is the core part of the mechanism, responsible for conducting tests, including the first test piece 2 and the second test piece 3, which are located on the test surface 11 at the positions of the first opening 13 and the second opening 14, and can approach and move away from each other, and contact the workpiece to be tested, thereby completing the test operation.

[0026] One side of the first test piece 2 has a plurality of contact pieces 21, which are used to contact the workpiece to be tested and provide test current or signal, and one side of the second test piece 3 has a plurality of contact pins 31, which contact the other side of the workpiece to be tested, forming a closed circuit path for conduction test.

[0027] The drive structure includes the first drive piece 41 and the second drive piece 42, which can be servo motors, hydraulic devices, electric telescopic rods, etc. In this example, they are servo motors. The two drive pieces are installed on the drive surface 12 and connected with the test pieces through the first opening 13 and the second opening 14. The first drive piece 41 controls the first test piece 2, and the second drive piece 42 controls the second test piece 3. Through the coordinated action of the two drive pieces, the first test piece 2 and the second test piece 3 move towards each other, thereby clamping the workpiece to be tested for testing.

[0028] This embodiment adopts double-motor drive to drive the first and second test pieces 3 to move in coordination with the test according to a certain rhythm. The first drive piece 41 drives the first test piece 2 to make the contact pieces 21 of the first test piece 2 press down and contact the contactor of the workpiece to be tested 7, while the second drive piece 42 drives the second test piece 3 to rise, so that the top of the insulating pin contacts the contactor of the workpiece to be tested 7, at which time a loop is formed for testing. Then the second drive piece 42 continues to drive the second test piece 3 to return to the initial position, at which time the top of the insulating pin is away from the contactor of the workpiece to be tested 7, and is in an open circuit state, thereby determining that the workpiece to be tested 7 has good conduction performance and is mutually insulated. At this time, the first test piece 2 continues to discharge high voltage, and if it is still in an open circuit state, the voltage resistance performance meets the requirements and meets the detection requirements. Then the first drive piece 41 returns to the initial position to start the next detection cycle, and the cycle is repeated to efficiently detect.

[0029] Reference Figure 1In an embodiment of the present application, the fixed frame 1 is connected with a fixed block 15 at the test surface 11, and the fixed block 15 is provided with guide rods 16 at both ends, and the first test piece 2 and the second test piece 3 are movably sleeved on the guide rods 16.

[0030] It can be understood that the first test piece 2 and the second test piece 3 are movably sleeved on the guide rods 16 and are fixed on the fixed frame 1 by the fixed block 15, and the arrangement of the guide rods 16 ensures that the first test piece 2 and the second test piece 3 can only move along the predetermined vertical direction, preventing the test pieces from deviating or tilting, making their movement more accurate and stable. Precise linear motion is crucial for conduction testing, because the relative position between the test pieces needs to be kept accurate to ensure the reliability of the test results. Through the design of the guide rods 16, the relative movement of the test pieces is limited, and test errors will not occur due to slight vibration or irregular movement of the device. Such design can improve the stability and consistency of the test, ensuring that each test is carried out under the same conditions, thereby reducing errors and deviations.

[0031] Referring to Figure 4 In an embodiment of the present application, the driving structure further comprises two rotating blocks 5 and two transmission rods 6, the two rotating blocks 5 are respectively connected to the first driving member 41 and the second driving member 42, and one end of the two transmission rods 6 is movably connected to the two rotating blocks 5, and the other end is movably connected to the first test piece 2 and the second test piece 3.

[0032] It can be understood that the driving structure further comprises two rotating blocks 5 and two transmission rods 6 for driving and controlling the test pieces. One end of the two rotating blocks 5 is connected to the output shaft of the motor, and the other end can rotate to a certain extent. The two transmission rods 6 are components for transmitting motion and force, one end of each of the two transmission rods 6 is connected to the two rotating blocks 5, and since the rotating blocks 5 are rotating components, the transmission rods 6 will move up and down accordingly with the rotation of the rotating blocks 5, and the other end of each of the two transmission rods 6 is connected to the first test piece 2 and the second test piece 3. Through this connection, the transmission rods 6 transmit the rotating motion of the rotating blocks 5 to the test pieces, prompting the test pieces to slide or move along the guide rods 16.

[0033] Referring to Figure 2 In an embodiment of the present application, the contact sheet 21 is formed with a sawtooth part 22 at one end facing the second test piece 3.

[0034] It can be understood that the sawtooth structure can increase the number of contacts between the contact piece 21 and the pin of the workpiece 7 to be tested. Compared with a smooth contact surface, the sawtooth structure can make the contact points more dispersed and increase the effective point positions in contact with the pin. At the same time, the sawtooth shape can grab the surface of the pin like a "hook" to increase the friction between the contact piece 21 and the pin. In this way, not only the firmness of the contact is improved, but also the contact failure or loosening caused by vibration or external force is reduced. The sawtooth contact piece 21 can uniformly distribute the pressure, so that the contact between the contact piece 21 and the pin is more uniform. Compared with the traditional planar contact, the sawtooth contact piece 21 can avoid the situation of excessive single-point contact pressure or poor contact, thereby improving the contact quality and stability.

[0035] Referring to Figure 2 In an embodiment of the present application, the second test piece 3 is provided with a protective block 32 on the side facing the first test piece 2, and the contact pin 31 passes through the protective block 32 and the end is exposed outside.

[0036] It can be understood that since the contact pin 31 is erected outside, it is easy to be bent and damaged by external force when contacting the workpiece 7 to be tested during the test. Therefore, the protective block 32 is arranged to protect the end of the contact pin 31, and the end of the contact pin 31 is clamped and fixed to avoid bending. At the same time, the end of the contact pin 31 is exposed outside the protective block 32, which does not affect the test.

[0037] Referring to Figure 1 In an embodiment of the present application, the fixing frame 1 is connected with a protective cover 17 at one end close to the first opening 13.

[0038] It can be understood that the protective cover 17 covers the driving structure below to prevent external substances (such as dust, moisture, and sundries) from entering, which can protect the internal components and also avoid personnel from contacting the running driving member. In addition, it can also improve the appearance of the equipment and keep it clean and tidy.

[0039] The utility model discloses technical scheme through adopting double motor drive, drive first, second test piece 3 according to certain beat movement cooperation test. First driving part 41 drive drive first test piece 2, make the contact sheet 21 of first test piece 2 press down and be measured workpiece 7 contact foot contact, with this, second driving part 42 drive drive second test piece 3 rise, make the top of insulating needle and measured workpiece 7 contact foot contact, form loop and test at this time, then second driving part 42 continue to drive second test piece 3 return initial position, at this time, the top of insulating needle is far from measured workpiece 7 contact foot, is in open circuit state, thereby judge measured workpiece 7 conduction performance is good, and mutual insulation. And at this time, first test piece 2 continue high voltage discharge, if still in open circuit state, then withstand voltage performance satisfies the requirement, meet the detection requirement, immediately, first driving part 41 return initial position, start the cycle of next detection, cycle, efficient detection.
