[0025] In an embodiment of the present application, as shown in Figs. 1-3 A pressure test mechanism is provided, comprising a probe pressure component 10, a pressure test fixture 20, a linear drive structure 30 and a base 40; the pressure test fixture 20 is slidingly connected to the base 40, and the pressure test fixture 20 is provided with a fixing cavity 50 for fixing the product 1; the probe pressure component 10 is arranged at one end of the base 40 away from the linear drive structure 30, and cooperates with the pressure test fixture 20 to perform pressure test on the product 1; the linear drive structure 30 is connected with the pressure test fixture 20, and can drive the pressure test fixture 20 to approach or move away from the probe pressure component 10.

[0026] Specifically, the pressure resistance test mechanism is mainly used for testing the pressure resistance performance of product 1, ensuring the insulation performance and safety of product 1 under high pressure conditions. The probe pressure resistance assembly 10 is the core part of the pressure resistance test mechanism, which detects whether product 1 can maintain insulation performance under specified pressure resistance by applying high voltage. The pressure resistance test fixture 20 is used to fix product 1, so that it can be stably placed on the test equipment. The fixture is provided with a fixing cavity 50 for accommodating and fixing product 1, and the linear drive structure 30 is responsible for driving the pressure resistance test fixture 20 to move along the base 40, so that the fixture can approach or move away from the probe pressure resistance assembly 10 to perform pressure resistance test. The base 40 is the supporting structure of the pressure resistance test mechanism. The pressure resistance test fixture 20 is installed on the base 40 through sliding connection, and the linear drive structure 30 drives the pressure resistance test fixture 20 to move. The probe pressure resistance assembly 10 is fixed at one end of the base 40, opposite to the position of the pressure resistance test fixture 20, and the two cooperate to perform pressure resistance test. The linear drive structure 30 is connected with the pressure resistance test fixture 20, and adjusts the distance between the fixture and the probe pressure resistance assembly 10 by driving the movement of the fixture. The pressure resistance test mechanism can effectively test the pressure resistance performance of product 1, ensure the safety of product 1 under high pressure conditions, and prevent electrical faults and safety accidents. The linear drive structure 30 can accurately control the position of the pressure resistance test fixture 20, ensure the appropriate distance between the probe pressure resistance assembly 10 and product 1, and improve the test precision. Through the automatic linear drive structure 30, the pressure resistance test process is more efficient, reducing the time and labor intensity of manual operation. The sliding connection design of the pressure resistance test fixture 20 makes the test mechanism adapt to products 1 of different sizes and shapes, improving the flexibility and applicability of the equipment. Due to the modular design of the pressure resistance test mechanism, each component is easy to disassemble and maintain, reducing the maintenance cost and complexity.

[0027] In this example, the pressure test fixture 20 includes a mounting base 21 and a fixed base 22; the mounting base 21 is slidingly connected with the base 40, and the mounting base 21 is connected with the moving end of the linear drive structure 30; the fixed base 22 is arranged on the mounting base 21, and the mounting base 21 is provided with a fixed cavity 50. Specifically, the mounting base 21 is the movable part of the pressure test fixture 20, which is slidingly connected with the base 40, allowing the fixture to move along the base 40. The mounting base 21 is also connected with the moving end of the linear drive structure 30, which drives its movement. The fixed base 22 is the fixed part of the pressure test fixture 20, which is arranged on the mounting base 21 and used to fix the product 1. The fixed base 22 is provided with a fixed cavity 50 for accommodating and fixing the product 1. The linear drive structure 30 is responsible for driving the mounting base 21 to move along the base 40, thereby changing the distance between the fixed base 22 and the probe pressure assembly 10 to perform pressure test. The mounting base 21 and the base 40 are connected by sliding connection, and the base 40 is provided with a sliding rail 41 or a sliding groove, and the mounting base 21 can slide freely on it. The mounting base 21 is connected with the moving end of the linear drive structure 30, and the linear drive structure 30 drives the mounting base 21 to move through mechanical connection or power transmission. The fixed base 22 is fixed on the mounting base 21, usually connected with the mounting base 21 by bolts, buckles or other fixing methods.

[0028] In this example, the bottom of the fixed base 22 is provided with an insulating bottom plate 23, which is fixedly connected with the mounting base 21. Specifically, the bottom of the fixed base 22 is provided with an insulating bottom plate 23, which is fixedly connected with the mounting base 21. The main function of the insulating bottom plate 23 is to provide electrical insulation, prevent current leakage or short circuit, and ensure the safety and accuracy of the test. The insulating bottom plate 23 is usually made of insulating materials such as plastic, ceramic or special insulating rubber, which has good electrical insulation performance. The use of the insulating bottom plate 23 improves the safety of the pressure test, prevents current leakage or short circuit, and protects the operators and test equipment. The insulating bottom plate 23 ensures that the current only passes through the product 1 during the test, and is not affected by other factors, improving the accuracy of the test results.

[0029] In this example, the fixed base 22 is provided with a positioning member 24, which is vertically arranged in the middle of the fixed base 22; the middle of the product 1 is provided with a positioning hole for the positioning member 24 to pass through. Specifically, the fixed base 22 is provided with a positioning member 24, which is vertically arranged in the middle of the fixed base 22, used to ensure the correct position of the product 1 in the fixed base 22. The middle of the product 1 is provided with a positioning hole, and the positioning member 24 passes through this positioning hole to fix the center position of the product 1, ensuring that the product 1 does not shift or rotate during the test.

[0030] In this example, the end of the positioning member 24 is designed in a circular truncated cone shape. Specifically, the positioning member 24 is a component in the fixture used to position the hole of the product 1, and its end is designed in a circular truncated cone shape, i.e., one end is larger in diameter and the other end is smaller in diameter, forming a tapered shape. The circular truncated cone-shaped end of the positioning member 24 helps to smoothly pass through the positioning hole of the product 1, reducing friction and damage to the positioning hole of the product 1 when inserted. When the product 1 is placed on the fixture, the circular truncated cone-shaped end of the positioning member 24 can be more easily aligned and passed through the positioning hole of the product 1, achieving accurate positioning. The design of the circular truncated cone-shaped end reduces the damage that may be caused when the positioning member 24 passes through the positioning hole of the product 1, protecting the integrity of the product 1. The circular truncated cone-shaped end helps to more accurately align the positioning hole, improving the positioning accuracy of the product 1 during transportation and testing. The shape of the circular truncated cone-shaped end can reduce the friction when inserted into the positioning hole, making the positioning process smoother. The design of the circular truncated cone-shaped end makes it easier for the operator to manually align and insert the positioning member 24, reducing the difficulty of operation. Since the positioning process is smoother and faster, the efficiency of the entire production line is improved, reducing downtime due to positioning problems. The design of the circular truncated cone-shaped end can adapt to positioning holes of different sizes, increasing the applicability of the fixture.

[0031] In this example, the positioning member 24 is provided with four protrusions 241 at one end inside the fixing cavity 50, and the four protrusions 241 are respectively located at the four corners of the positioning member 24. Specifically, when the product 1 is placed on the fixing seat 22, the protrusions 241 of the positioning member 24 help to ensure the correct position of the positioning member 24 in the fixing seat 22, thereby ensuring that the product 1 can be accurately fixed. The four protrusions 241 of the positioning member 24 are respectively located at the four corners of the positioning member 24, which cooperate with the internal structure of the fixing seat 22 to ensure the stability of the positioning member 24. The design of the protrusions 241 enhances the stability of the connection between the positioning member 24 and the fixing seat 22, reducing the shaking during transportation. The protrusions 241 help the positioning member 24 to maintain the correct position in the fixing seat 22, thereby improving the positioning accuracy of the product 1. The protrusions 241 can reduce the wear of the positioning member 24 in the fixing seat 22, prolonging the service life of the positioning member 24. The design of the protrusions 241 makes it easier to install and adjust the positioning member 24 to the correct position, improving the flexibility of the production line.

[0032] In this example, the linear drive structure 30 includes a linear motor 31 and a lead screw 32, the linear motor 31 is mounted on the base 40, and the lead screw 32 is rotationally connected with the base 40; the main shaft of the linear motor 31 is connected with the lead screw 32; the pressure resistance test fixture 20 is threadedly connected with the lead screw 32. Specifically, the linear motor 31 is mounted on the base 40 and fixedly connected with the base 40, providing a power source for the entire linear drive structure 30. The lead screw 32 is rotationally connected with the base 40, and its end is connected with the main shaft of the linear motor 31, so that the motor drives the lead screw 32 to rotate when rotating. The pressure resistance test fixture 20 is connected with the lead screw 32 through threads, and moves along the axis of the lead screw 32 as the lead screw 32 rotates. The linear motor 31 provides high-precision linear movement, so that the pressure resistance test fixture 20 can be accurately positioned to the test position. The fast response capability of the linear motor 31 enables the pressure resistance test fixture 20 to quickly move to the desired position, improving test efficiency. Due to the direct driving mode between the linear motor 31 and the lead screw 32, wear and energy loss in the traditional transmission system are reduced.

[0033] In this example, the base 40 is provided with a slide rail 41 extending along the length direction of the base 40, and the pressure resistance test fixture 20 is slidingly connected with the slide rail 41. Specifically, the slide rail 41 extends along the length direction of the base 40 to guide the movement of the pressure resistance test fixture 20. The pressure resistance test fixture 20 is connected with the slide rail 41 through sliding elements such as sliders, guide wheels, etc., which move on the slide rail 41 to drive the fixture to move along the length direction of the base 40. The slide rail 41 provides a smooth movement path to ensure the stability and reliability of the pressure resistance test fixture 20 during movement.

[0034] In this example, the probe pressure resistance assembly 10 includes a pressure resistance test seat 11, a pressure resistance connecting plate 12, a pressure resistance cylinder 13, and a plurality of probes 14, the pressure resistance cylinder 13 is arranged on the pressure resistance test seat 11; the pressure resistance connecting plate 12 is connected with the lifting end of the pressure resistance cylinder 13; each probe 14 is connected to the pressure resistance connecting plate 12, and each probe 14 corresponds to a terminal on the product 1. Specifically, the pressure resistance test seat 11 is the basic part of the pressure resistance test mechanism, providing a stable platform for testing. The pressure resistance connecting plate 12 is used to connect the lifting end of the pressure resistance cylinder 13, ensuring that the movement of the cylinder can be transmitted to the probes 14. The pressure resistance cylinder 13 is connected with the pressure resistance test fixture 20 through the linear drive structure 30, driving the pressure resistance test fixture 20 to approach or move away from the probe pressure resistance assembly 10, realizing the contact or separation of the probes 14 and the terminals of the product 1. The probes 14 are connected to the pressure resistance connecting plate 12 for establishing electrical connection with the terminals on the product 1 to perform pressure resistance test. Each probe 14 is connected to the pressure resistance connecting plate 12 and corresponds to a terminal on the product 1, ensuring that each probe 14 can accurately contact the corresponding terminal.

[0035] In the present example, the voltage withstanding test mechanism further comprises a detection sensor 60 electrically connected with the linear driving structure 30 and the probe voltage withstanding assembly 10, which is arranged beside the voltage withstanding test fixture 20 and used for detecting whether the voltage withstanding test fixture 20 is installed with the product 1. Specifically, the detection sensor 60 is electrically connected with the linear driving structure 30 and the probe voltage withstanding assembly 10 and arranged beside the voltage withstanding test fixture 20.

When the voltage withstanding test fixture 20 moves to the test position, the detection sensor 60 senses whether there is the product 1 on the fixture through the electrical connection. If there is no product 1 on the fixture, the detection sensor 60 will send a signal to prevent the test from being meaningless or possibly damaging the equipment.
