Description

Technical Field

[0001] The utility model relates to the field of airtightness detection, in particular to the technical field of detecting a thermostat seat of a diesel engine by water immersion, and specifically relates to a water immersion detection tooling for a thermostat seat of a diesel engine. Background Art

[0002] There is a prior art that after the processing of a thermostat seat of a diesel engine, it is necessary to block the through holes or channels around it and then immerse it in water. Gas is injected into the thermostat seat of the diesel engine, and it is detected whether bubbles will float out in the water to judge whether the airtightness of the thermostat seat of the diesel engine is qualified. However, because the overall structure of this kind of thermostat seat of the diesel engine is complex, and there are many through holes and pipes that need to be closed, and the bottom on one side and the bottom on the other side are not at the same height. If plugs are simply used to block these through holes, when gas is injected into the thermostat seat of the diesel engine during detection, the plugs will loosen, resulting in unreliable airtightness detection results.

[0062] The present utility model provides a water immersion detection tooling for a diesel engine thermostat seat, which is used in the detection process of the diesel engine thermostat seat. However, the structures of the tooling plate 1, the upper and lower hole plugging and limiting module 2, the front and rear hole plugging and supporting module 3, the left and right hole plugging and supporting module 4, and the liquid discharge pipeline plugging and limiting module 5 are particularly suitable for detecting whether the air tightness of the diesel engine thermostat seat is qualified.

[0063] Generally speaking, the water immersion detection tooling for a diesel engine thermostat seat proposed by the present utility model mainly includes: the tooling plate 1, the upper and lower hole plugging and limiting module 2, the front and rear hole plugging and supporting module 3, the left and right hole plugging and supporting module 4, and the liquid discharge pipeline plugging and limiting module 5. Among them, reference can be made to Figure 1 , which shows the layout relationship of the tooling plate 1, the upper and lower hole plugging and limiting module 2, the front and rear hole plugging and supporting module 3, the left and right hole plugging and supporting module 4, and the liquid discharge pipeline plugging and limiting module 5.

[0064] When using the water immersion detection tooling for the thermostat seat of a diesel engine proposed by the present utility model, a sealing ring 27 is inserted into the bottom vent of the thermostat seat to be detected. Align the vent on one side of the bottom of the thermostat seat with the air inlet nozzle 28, and press the right housing of the thermostat seat against the support rod 418 of the right housing of the thermostat seat. Rotate the No. 4 T-shaped frame 414 to insert the drain plug 416 into the drain port on the left side of the thermostat seat. Rotate the No. 7 T-shaped threaded wrench 55 to block the sensor mounting hole on the drain pipe on one side of the thermostat seat with the sensor mounting hole plug 56, initially limiting the installation position of the thermostat seat to be detected. Then, sequentially control the T-shaped threaded wrenches in the front and rear hole blocking support module 3, the left and right hole blocking support module 4, and the drain pipe blocking and limiting module 5 to close each through hole with a plug or a pressing plate, and at the same time complete the limiting of the thermostat seat in the front, rear, left, and right directions. Finally, control the No. 1 T-shaped threaded wrench 24 in the upper and lower hole blocking and limiting module 2 to completely limit the thermostat seat on the top of the tooling plate 1. Connect the air inlet nozzle 28 to the air pump through a trachea, and then place the entire water immersion detection tooling for the thermostat seat of the diesel engine into water. Start the air pump to ventilate the diesel engine thermostat seat to be tested, and judge whether the airtightness of the diesel engine thermostat seat is qualified by observing whether bubbles emerge. The diesel engine thermostat seat is limited in all directions and will not move. Moreover, when detecting, the plugs or pressing plates on one side of the plugs closing each hole of the diesel engine thermostat seat are all pressurized by the locking screw when inflating into the thermostat seat, and will not cause the internal air pressure of the diesel engine thermostat seat to increase, resulting in displacement or ejection of the plugs and pressing plates.

[0065] The above-mentioned upper and lower hole plugging and limiting module 2 is arranged in the middle of one side of the top of the tooling plate 1. The upper and lower hole plugging and limiting module 2 includes: a first positioning column 21, a first T-shaped threaded wrench 24, a first pressing plate 25, a first positioning pin 26, a sealing ring 27 and an air inlet nozzle 28. Among them, a pair of first positioning columns 21 are provided. The pair of first positioning columns 21 are arranged at intervals on one side of the top of the tooling plate 1 through bolt connection. A first connecting plate 22 is placed on the tops of the pair of first positioning columns 21. The front and rear sides of the first connecting plate 22 are penetrated by a first locking screw 23. The bottom of the first locking screw 23 vertically penetrates the first connecting plate 22 and is threadedly fitted into the first positioning column 21. A first T-shaped threaded wrench 24 is penetrated in the middle of the first connecting plate 22. The first pressing plate 25 is welded to the bottom end of the first T-shaped threaded wrench 24. By rotating the first T-shaped threaded wrench 24 to drive the up and down movement of the first pressing plate 25, the thermostat base to be measured can be pressed on the tooling plate 1, realizing the up and down direction limit of the thermostat base. A first positioning pin 26 is penetrated around the first T-shaped threaded wrench 24 at the top of the first pressing plate 25. The first positioning pin 26 corresponds to the bolt holes at the top of the thermostat base to be measured. The first positioning pin 26 can be stuck in the bolt holes to realize the positioning connection between the first pressing plate 25 and the thermostat base. If the parallelism of the top of the thermostat base is poor and the heights on both sides are not in the same plane or uneven, the first pressing plate 25 and the thermostat base will not fit completely and there will be a gap. Bubbles will appear during the water immersion test, and the first pressing plate 25 will not cover the bolt holes. If the bolt holes are loose or have shrinkage holes, resulting in the bottom of the bolt holes being connected to the inside of the thermostat base, bubbles will appear during the water immersion test.
