Description

Technical Field

[0001] The invention relates to the technical field of automobile radiator detection, in particular to an automobile radiator detection device and a detection method. Background Art

[0002] A car radiator is a device used for heat exchange. Its main function is to dissipate heat from the coolant through the radiator core to reduce the temperature of the engine and ensure that the engine can run at a normal temperature. If the engine cannot dissipate heat in time during operation, it may cause overheating, which in turn may cause deformation or damage to components, and ultimately lead to serious mechanical failure.

[0003] After the car radiator is processed and formed, it is usually necessary to test the car radiator. Its main purpose is to verify its heat dissipation performance, sealing and whether there are any defects that may affect its normal operation. Among them, the sealing test is particularly important. It is to ensure that when the car radiator is installed on the car for use, there will be no leakage affecting the cooling effect. During the test, the car radiator is placed inside the water tank, and compressed air is passed into the radiator to check whether there are bubbles to determine its sealing.

[0004] In this detection method, the vent pipe and the filling port on the radiator need to be locked, and then air is injected into the radiator. During the locking process, the locking between the filling port and the vent pipe connector needs to ensure that no gap is generated. In order to avoid some air leaking from the connection, causing errors in the entire detection effect, when a gap is generated in the locking, the clean water used for wet inspection will enter the radiator through the gap, affecting the overall performance of the radiator. At the same time, the water remaining in the radiator will also corrode the radiator, causing the entire radiator life to be greatly shortened. Summary of the invention

[0016] The purpose of the present invention is to firmly fix the liquid filling port and the vent pipe of the automobile radiator together when the automobile radiator is tested for air tightness, so as to avoid the air escaping from the inside of the automobile radiator.

[0017] To achieve the above object, the present invention provides the following technical solution: an automobile radiator detection device and a detection method, comprising the following steps:

[0018] First, place the car radiator on the lifting plate, then start the air cylinder to make the push rod drive the lifting plate to move toward the bottom of the placement table, and after starting the motor, drive the sliding rod to rotate, so that the moving plate moves toward the support seat, so that it is convenient for the clamping blocks on the support seat to lock and clamp the upper and lower sides of the car radiator. At the same time, during the movement of the car radiator, the liquid filling port on the car radiator will be squeezed with the annular sealing ring on the telescopic ring plate, so that the gap between the liquid filling port and the vent pipe is blocked by the annular sealing ring, thereby tightening the liquid filling port of the car radiator, so that it is close to and retracted toward the liquid filling port of the car radiator;

[0019] During the squeezing process of the annular sealing ring by the liquid injection port, the telescopic ring plate moves inside the clamping cylinder, and the moving telescopic ring plate pushes the matching component to move, and then the matching plate moves synchronously, and then the matching plate drives the triangular shifting plate on the L-shaped support rod to slide on the supporting block, and then the squeezing plate approaches the annular push plate, pushing the annular push plate to rise, and the rising annular push plate can drive the rotating plate to rotate, and the fan-shaped clamping plates movably arranged on the other side of the rotating plate can be retracted under the action of the plug-in slot and the matching rod;

[0020] Then, the air is pumped into the car radiator through the vent pipe. Under the cooperation of the water in the water tank of the car radiator and the air introduced into the car radiator, a wet inspection environment is formed. Whether bubbles are generated in the water is observed to judge whether the air tightness of the entire car radiator is good, so that the car radiators with poor air tightness can be screened out.

[0021] Finally, after the inspection is completed, the matching plate will be reset under the action of the third spring, thereby driving the triangular shift plate to reset, so that the extrusion plate no longer pushes the annular push plate, and the annular push plate will be reset under the action of the second spring, so that the entire device and the liquid filling port on the car radiator are no longer locked, and then the staff can take out the car radiator that has been inspected.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention, through the action between the clamping block, the rotating slide plate and the bonding plate, can push the bonding plate to move toward the inside of the support seat when the automobile radiator is close to the surface of the bonding plate, so that the clamping block can rotate at an angle to clamp the upper and lower sides of the automobile radiator. During the clamping process, the entire automobile radiator will not shake, and the entire air tightness will not be affected when air is injected into the radiator, so that in the locked state, there will be no gap caused by shaking, resulting in errors in the entire detection effect;

[0024] 2. When the liquid injection port on the radiator and the annular sealing ring on the telescopic ring plate are in contact and plugged together, the deformation of the annular sealing ring can completely block the gap between the liquid injection port and the vent pipe, ensuring that no air leakage occurs during the entire detection process. At the same time, during the sealing process of the liquid injection port, the compression spring arranged on the outside of the telescopic ring plate can also provide a certain buffer, so that when the liquid injection port squeezes the annular sealing ring, the entire liquid injection port will not be damaged due to excessive impact;

[0025] 3. During the movement of the telescopic ring plate, the matching plate will be pushed to move, thereby pushing the extrusion plate to move toward the engaging cylinder, causing the annular push plate to move. The moving annular push plate can cause the fan-shaped card plate to contract to stabilize the liquid injection port, thereby further locking the connection between the liquid injection port and the vent pipe without shaking. When the fan-shaped card plate contracts, the liquid injection port is firmly fixed inside the engaging cylinder, forming a stable locking state. BRIEF DESCRIPTION OF THE DRAWINGS
