Description

Technical Field

[0001] The utility model relates to the field of radiators, in particular to an air tightness detection device for radiators. Background Art

[0002] A radiator includes an upper water chamber, a lower water chamber and a radiator core. In most radiators, an inlet hole and an outlet hole are respectively arranged at the upper and lower ends.

[0003] The Chinese patent with the publication number CN201926367U discloses a radiator, which includes a core body, an inlet chamber connected to one side of the core body, an outlet chamber connected to the other side of the core body, and side plates connected to the inlet chamber and the outlet chamber. The inlet chamber includes an inlet chamber body, and an inlet is arranged outside the inlet chamber body. The outlet chamber includes an outlet chamber body, and an outlet is arranged outside the outlet chamber body.

[0004] After the radiator with the above structure is produced and installed, it is also necessary to detect the air tightness of its interior. During the detection, it is necessary to block the inlet or the outlet first, and then inflate the interior of the radiator from the other port to detect the air tightness of the radiator. If manual detection is used to detect the air tightness of the radiator, the efficiency is relatively low. Content of the Utility Model

[0005] Aiming at the disadvantages that after the existing radiator is produced and installed, it is necessary to detect the air tightness of its interior, and if manual detection is used to detect the air tightness of the radiator, the efficiency is relatively low, the utility model provides an air tightness detection device for radiators.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] An air tightness detection device for radiators includes a workbench for placing the radiator. The upper and lower ends of the radiator are respectively provided with an inlet hole and an outlet hole. A detection device for detecting the air tightness of the radiator is arranged on the workbench. The detection device includes a positioning component arranged on the workbench for positioning the bottom of the radiator, a blocking device arranged above the workbench for blocking the inlet hole at the top of the positioned radiator, and an inflation device arranged below the workbench for inflating the interior of the radiator through the outlet hole at the bottom of the radiator.

[0008] With the above solution, the positioning component can position the radiator when the radiator needs to be subjected to airtightness detection, facilitating subsequent plugging of the water inlet hole of the radiator by the plugging device and inflation of the radiator interior by the inflation device. The provided plugging device can plug the water inlet hole at the top of the radiator. At this time, when gas is filled into the radiator interior, the airtightness of the radiator can be detected. The provided inflation device fills the gas it generates into the radiator interior through the water outlet hole of the radiator.

[0009] Preferably, the positioning component includes a positioning block arranged on the workbench, and a positioning groove having the same shape and size as the bottom of the radiator and for the bottom of the radiator to be inserted therein is arranged at the top of the positioning block.

[0010] With the above solution, the positioning groove arranged in the positioning block can position the radiator when the radiator needs to be subjected to airtightness detection, enabling the inflation device arranged below the workbench to smoothly fill the gas it generates into the radiator interior. At the same time, it can also make the plugging device face the water inlet hole directly, enabling the plugging device to partially insert into the water inlet hole, thereby detecting the airtightness of the radiator.

[0011] Preferably, the plugging device includes a cylinder with a vertically downward extending end arranged above the workbench, and a plug fixed at the end of the extending end of the cylinder and capable of partially inserting into the water inlet hole at the top of the positioned radiator after descending is provided.

[0012] With the above solution, the cylinder arranged above the workbench can drive the plug fixedly installed at the end of its extending end to descend and insert into the water inlet hole at the top of the radiator after the bottom of the radiator is inserted into the positioning groove, thereby sealing the water inlet hole, facilitating subsequent airtightness detection of the radiator interior, and at the same time reducing the probability of the bottom of the radiator lifting upward when the inflation device is started.

[0013] Preferably, the inflation device includes an inflator arranged below the workbench, an air outlet pipe is arranged at one end of the inflator close to the workbench, a jack for the partial insertion of the air outlet pipe is arranged on the workbench, and a ventilation groove allowing the gas in the air outlet pipe to pass through the positioning block and then enter the radiator through the water outlet hole at the bottom of the radiator is arranged at the bottom of the positioning groove.

[0014] With the above solution, the inflator arranged below the workbench can fill the gas into the radiator interior through the jack and the ventilation groove when the bottom of the radiator is positioned in the positioning groove and the plugging device seals the water inlet hole at the top of the radiator, thereby detecting the airtightness of the radiator.

[0015] Preferably, the ventilation groove is rectangular and its size is larger than the diameter of the air outlet pipe.

[0016] With the above solution, the shape of the ventilation groove is set to be rectangular and its size is set to be larger than the diameter of the outlet pipe, so that when the size of the water outlet hole at the bottom of the radiator changes, the inflator can still pass the gas in the inflator into the radiator through the ventilation groove for airtightness detection.

[0017] Preferably, a pressing component is further arranged on the workbench to press the bottom of the radiator against the positioning groove after the positioning component completes the positioning of the bottom of the radiator.

[0018] Preferably, the pressing component includes at least one group of pressing blocks symmetrically arranged around the positioning block. A clamping lever cylinder with the same number as the pressing blocks and capable of driving the pressing blocks to flip is arranged below the workbench. An avoidance component for avoidance when the clamping lever cylinder drives the pressing blocks to flip is further arranged on the workbench. When the clamping lever cylinder extends, the pressing blocks flip downward to press the bottom of the radiator in the positioning groove; when the clamping lever cylinder retracts, the pressing blocks flip upward to move away from the bottom of the radiator in the positioning groove.

[0019] With the above solution, the clamping lever cylinder can drive the pressing blocks to flip close to or away from the radiator in the positioning groove. When the clamping lever cylinder drives the pressing blocks close to the bottom of the radiator in the positioning groove, at this time the pressing blocks will directly approach the bottom of the radiator in the positioning groove and when they abut against it, press the bottom of the radiator against the positioning groove, thereby reducing the probability that the bottom of the radiator is lifted by the gas generated by the inflating device, enabling the bottom of the radiator to always abut against the bottom of the positioning groove when the inflating device inflates, and the arranged avoidance component can avoid when the clamping lever cylinder drives the pressing blocks to flip.

[0020] Preferably, the avoidance component includes avoidance grooves arranged on the workbench with the same number as the pressing blocks.

[0021] With the above solution, the arranged avoidance grooves can avoid when the clamping lever cylinder drives the pressing blocks to flip, so that the clamping lever cylinder can drive the pressing blocks to flip to press the bottom of the radiator placed in the positioning groove against the positioning groove.

[0022] Since the utility model adopts the above technical solutions, it has remarkable technical effects: through the arranged positioning component, the position of the radiator can be positioned when the radiator needs to be subjected to airtightness detection, so as to facilitate the subsequent plugging device to plug the water inlet hole of the radiator and the inflating device to inflate the inside of the radiator. The arranged plugging device can plug the water inlet hole at the top of the radiator. At this time, when the gas is filled into the inside of the radiator, the airtightness of the radiator can be detected, and the arranged inflating device fills the gas generated by it into the inside of the radiator through the water outlet hole of the radiator.
