Technical Field

[0001] This utility model relates to the technical field of pressure resistance testing machines, specifically a multi-station pressure resistance testing machine. Background Technology

[0002] Multi-station withstand voltage testing machines are mainly used in the field of industrial product quality inspection, especially suitable for products such as electronic components, electrical equipment, medical devices, and automotive parts that need to withstand specific pressures or voltages. Their core business is to conduct batch testing of the workpiece's withstand voltage limit, structural stability, and other properties by simulating the stress environment of the product in actual use, ensuring that the product meets safety standards and usage requirements.

[0003] Most testing machines only have a single testing station, and can only test one workpiece at a time, which is difficult to meet the high-efficiency testing needs of mass production. During the testing process, such as the flying debris generated in the air when the metal workpiece is under pressure and the dust generated by the friction of the plastic parts, there is a certain impact on the health of the operators, which pollutes the environment and affects the efficiency of operation. A multi-station pressure resistance testing machine is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: A multi-station withstand pressure testing machine includes a lower frame 1, a workbench 2 fixedly connected to the upper surface of the lower frame 1, an upper frame 3 fixedly connected to the upper surface of the workbench 2, a dust removal device 4 fixedly connected to the middle of the rear end of the lower frame 1, a lower fixed mold 5 fixedly connected to the middle of the upper surface of the workbench 2, and limit rods 6 fixedly connected to the four corners of the inner wall of the upper frame 3. The dust removal device 4 includes a mounting base 401. A dust collection pipe 402 is fixedly connected to the middle of the upper surface of the mounting base 401. Dust collection fans 403 are fixedly connected to both sides of the dust collection pipe 402. A suction hose 404 is fixedly connected to the top of the dust collection pipe 402. A dust collection hood 405 is fixedly connected to the front end of the suction hose 404. The dust collection hood 405 is compatible with the lower fixed mold 5. Connecting blocks 406 are fixedly connected to both sides of the dust collection hood 405. An electric telescopic rod 407 is fixedly connected to the rear end of the connecting block 406. A positioning groove 408 is fixedly connected to the rear end of the electric telescopic rod 407. The positioning groove 408 is connected to the workbench 2. A collection box 409 is slidably connected to the bottom of the inner wall of the dust collection pipe 402. The lower frame 1, the workbench 2, and the upper frame 3 form the basic framework of the testing machine, providing installation support for other components. The fixed mold 5 is used to place the workpiece to be tested. The limiting rod 6 limits and guides the movement of the connecting plate 9, ensuring a smooth and accurate pressing process. In the dust removal device 4, the dust suction fan 403 generates suction, allowing air to enter the dust suction pipe 402 from the dust suction hood 405. The suction hose 404 can be extended. During use, the dust suction hood 405 moves with the electric telescopic rod 407, pushing the connecting block 406 to ensure that the dust suction hood 405 contacts the surface to be cleaned, completing the cleaning work of the lower fixed mold 5. Dust is sucked in along with the air. In the dust suction pipe 402, the dust gradually settles into the collection box 409 due to gravity and airflow. The collection box 409 can be periodically removed to clean the dust. The positioning groove 408 is used to install the electric telescopic rod 407 and to position the connecting block 406, ensuring its stable operation.

[0018] Furthermore, a hydraulic pump 7 is fixedly connected to the middle of the upper surface of the upper frame 3. The output end of the hydraulic pump 7 is fixedly connected to the main hydraulic lifting rod 8. The hydraulic pump 7 is driven by an electric motor to convert electrical energy into hydraulic energy, compress the hydraulic oil to generate high pressure, and the high pressure oil is transported to the main hydraulic lifting rod 8 through pipelines to push the main hydraulic lifting rod 8 to perform telescopic movement, thereby realizing the lifting and lowering control of the lower pressure head 11 and providing a power source for the pressure resistance test.

[0019] Furthermore, a connecting plate 9 is fixedly connected to the bottom of the main hydraulic lifting rod 8. The connecting plate 9 is connected to the limiting rod 6. The connecting plate 9 is fixedly connected to the bottom of the main hydraulic lifting rod 8 and slidably connected to the limiting rod 6. When the main hydraulic lifting rod 8 drives the connecting plate 9 to move up and down, the limiting rod 6 restricts the movement direction of the connecting plate 9 to prevent it from deviating or shaking, ensuring that the lower pressure head 11 can accurately pressurize the workpiece in the lower fixed mold 5.

[0020] Furthermore, several auxiliary hydraulic lifting rods 10 are fixedly connected to the bottom of the connecting plate 9. A lower pressure head 11 is fixedly connected to the bottom of the auxiliary hydraulic lifting rod 10. The lower pressure head 11 is adapted to the lower fixed mold 5. The main hydraulic lifting rod 8 drives the auxiliary hydraulic lifting rods 10 to move through the connecting plate 9. The auxiliary hydraulic lifting rods 10 further transmit pressure to the lower pressure head 11. The auxiliary hydraulic lifting rods 10 can independently or collaboratively adjust the pressing position and pressure of the lower pressure head 11 according to the testing requirements of different workpieces, so that the lower pressure head 11 can fully contact the workpiece in the lower fixed mold 5 and apply appropriate pressure to complete the pressure resistance test.

[0021] Furthermore, a warning light 12 is fixedly connected to one side of the upper surface of the workbench 2, and a control panel 13 is fixedly connected to the other side of the upper surface of the workbench 2. The control panel 13 is the operation control center of the testing machine. The warning light 12 is used to emit light signals during the operation of the equipment. When the equipment malfunctions, the pressure is abnormal, or other situations that require warning occur, the warning light 12 will light up to remind the operator to pay attention and take appropriate measures.

[0022] Furthermore, a tool cabinet 14 is fixedly connected to the inner wall of the lower frame 1, and mounting plates 15 are fixedly connected to the four corners of the lower surface of the lower frame 1. The tool cabinet 14 is installed on the inner wall of the lower frame 1 and is used to store the tools required during the testing process.

[0023] Furthermore, a caster 16 is fixedly connected to one side of the lower surface of the mounting plate 15, and a foot cup 17 is rotatably connected to the other side of the lower surface of the mounting plate 15 via a thread. The caster 16 facilitates the movement of the testing machine, enabling the equipment to be flexibly transported between different work sites. After the equipment is moved to the designated position, the height of the foot cup 17 can be adjusted to keep the testing machine stable, and the level of the equipment can be adjusted to ensure the accuracy of the pressure resistance test.

[0024] Working principle: In use, the equipment is moved to a suitable position using the casters 16 at the bottom of the lower frame 1, and then the feet 17 are adjusted to make the equipment stable and fixed. The operator places the workpiece to be tested on the lower fixed mold 5, sets the test parameters through the control panel 13, and starts the equipment. The hydraulic pump 7 works, converting electrical energy into hydraulic energy, which drives the main hydraulic lifting rod 8 to extend and retract. The main hydraulic lifting rod 8 drives the connecting plate 9 to descend smoothly along the limit rod 6. The auxiliary hydraulic lifting rod 10 at the bottom of the connecting plate 9 moves accordingly, so that the lower pressure head 11 approaches and contacts the workpiece. According to the set parameters, the auxiliary hydraulic lifting rod 10 further applies pressure, and works with the lower fixed mold 5 to perform a pressure resistance test on the workpiece.

[0025] During the test, the warning light 12 displays the equipment status in real time. It may light up green during normal operation and turn red if there is an abnormal pressure or malfunction. At the same time, the dust removal fan 403 in the dust removal device 4 runs continuously, sucking dust and debris generated in the air during the test into the dust suction pipe 402 through the dust suction hood 405, and finally settling into the collection box 409. The suction hose 404, connecting block 406 and electric telescopic rod 407 facilitate the adjustment of the position of the dust suction hood 405. The collection box 409 can be periodically removed for cleaning. After the test is completed, the hydraulic system drives each lifting rod to reset, the lower pressure head 11 rises, and the operator removes the tested workpiece, completing one test process. Throughout the process, the workbench 2 and the upper frame 3 provide stable support for each component, ensuring accurate and safe testing.
