Description

Technical Field

[0001] This utility model relates to the field of radiator core testing technology, and in particular to an automatic insulation withstand voltage testing fixture. Background Technology

[0002] In automobile manufacturing, the air conditioning system is a crucial component, and the radiator core is one of the key components within it. The automotive radiator is an indispensable part of the water-cooled engine cooling system and is evolving towards lighter, more efficient, and more economical designs. The structure of automotive radiators is also constantly adapting to these new developments. An automotive radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. The assembly of the radiator core is critical to the performance and efficiency of the air conditioning system. During operation, the radiator core contains flowing heat-generating liquid within its pipes, dissipating heat outwards. Therefore, the sealing, insulation, and pressure resistance of the radiator core are extremely important. To address this, an automatic insulation and pressure resistance testing fixture is proposed.

[0003] Patent CN214373931U discloses a heatsink core assembly withstand voltage testing device, including a conveying mechanism, a clamping mechanism, a positioning mechanism, and a withstand voltage testing component. The positioning mechanism is positioned on the conveying mechanism corresponding to the conveying path. A clamping mechanism is located on the front side of the positioning mechanism in the conveying direction, and the clamping mechanism clamps the heatsink to be tested after positioning on the conveying mechanism. The withstand voltage testing component performs a withstand voltage test on the heatsink. By conveying the heatsink core assembly through the conveying mechanism, positioning and clamping it through the positioning and clamping mechanisms, and performing the withstand voltage test through the withstand voltage testing component, semi-automatic and fully automated withstand voltage testing can be achieved, reducing labor intensity and improving testing efficiency.

[0004] The existing automatic insulation withstand voltage testing fixtures have the following drawbacks: 1. The current withstand voltage test is mainly a manual withstand voltage test, which is labor-intensive, inefficient and inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide an automatic insulation withstand voltage testing fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic insulation withstand voltage testing fixture, comprising a base plate, wherein positioning blocks a, b, c, and d are fixedly connected to the surface of the base plate, forming a positioning groove between the positioning blocks a, b, c, and d, and a radiator core is placed in the positioning groove; a cylinder mounting seat is fixedly connected to the surface of the base plate, and a first cylinder is fixedly connected to the surface of the cylinder mounting seat; a swing arm is rotatably connected to the movable end of the first cylinder; a connecting rod is fixedly connected to the lower surface of the swing arm; and a connecting rod is fixedly connected to the lower surface of the connecting rod. It has a pressure head, and the surface of the base plate is also equipped with an insulation testing mechanism. During the withstand voltage test, the radiator core is placed in the positioning groove. The radiator core is limited by positioning blocks a, b, c, and d. By controlling the operation of the first cylinder, the power output end of the first cylinder moves, which drives the swing arm to move. The movement of the swing arm drives the connecting rod to move. One end of the connecting rod drives the pressure head to move. The pressure head squeezes the surface of the radiator core, thereby realizing the withstand voltage test. The swing arm can be rotated to change the test point, which can flexibly change the test point and ensure the accuracy of the withstand voltage test.

[0007] As a preferred embodiment, the insulation testing mechanism includes a cylinder support, a second cylinder, a connecting block, and a probe. The cylinder support is also fixedly connected to the surface of the base plate, and the second cylinder is fixedly connected to the top of the cylinder support. The connecting block is fixedly connected to the movable end of the second cylinder. When the second cylinder is controlled to run, the power output end of the second cylinder moves, which drives the connecting block to move. The movement of the connecting block drives the probe to move until the probe abuts against the surface of the radiator core. The probe is used to perform insulation testing on the radiator core. The insulation testing operation is simple and convenient, and easy to use.

[0008] As a preferred embodiment, a probe is fixedly connected to the side wall of the connecting block, with one end of the probe abutting against the surface of the radiator core. The radiator core is then subjected to insulation testing using the probe. A high voltage is applied to the test point by the probe, and the presence of electric sparks or arc discharge is observed to determine if there are any insulation problems.

[0009] As a preferred embodiment, the base plate is made of bakelite material; the base plate made of bakelite material has good insulation properties, can withstand high voltage, is non-conductive, can maintain high mechanical strength, and has certain pressure resistance and impact resistance.

[0010] As a preferred embodiment, the pressure head is made of polyurethane material; the pressure head made of polyurethane material has excellent mechanical properties, such as wear resistance, good elasticity and flexibility, and can maintain its original shape when no force is applied, but can deform under external force and return to its original shape after the external force is removed. In addition, it is relatively lightweight, which can reduce the structural load, facilitate pressure resistance testing, and avoid scratching the surface of the radiator core.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. During the pressure test, the radiator core is placed in the positioning groove. The radiator core is limited by positioning blocks a, b, c, and d. When the first cylinder is running, the power output end of the first cylinder moves, which drives the swing arm to move. The movement of the swing arm drives the connecting rod to move. One end of the connecting rod drives the pressure head to move. The pressure head squeezes the surface of the radiator core, thereby achieving the pressure test. The swing arm can be rotated to change the test point, which can flexibly change the test point and ensure the accuracy of the pressure test.

[0013] 2. When the second cylinder is running, the power output end of the second cylinder moves, which drives the connecting block to move. The moving connecting block drives the probe to move until the probe comes into contact with the surface of the radiator core. The probe is used to perform insulation testing on the radiator core. A high voltage is applied to the test point by the probe, and the presence of electric sparks or arc discharge is observed to determine whether there is a problem with the insulation. The insulation testing operation is simple and convenient and easy to use. Attached Figure Description
