Wherein the first elastic piece 71, the second elastic piece 72 and the guide piece 74 are integrally formed.
As shown in fig. 1, sealing cotton 8 is adhered to the table top of the workbench 1, the side wall of the fixed pressing plate 42 close to the workbench 1, and the side wall of the bolster tooling 5 contacting the workpiece 2.
The implementation principle of the embodiment is as follows:
the workpiece 2 to be detected is placed on the workbench 1, the air inlet duct 21 of the workpiece 2 is communicated with the detection cavity 12 on the workbench 1, and the side wall between the air inlet duct 21 and the air outlet duct 22 of the workpiece 2 is in contact with the side wall of the bolster tool 5.
And then, starting the air pressure cylinder 41, wherein the air pressure cylinder 41 can push the fixed pressing plate 42 to be tightly abutted to the workpiece 2 so as to seal and block the air outlet channel 22 of the workpiece 2. Since the workpiece 2 is a hexagonal prism, it is placed on the table 1 and easily falls down under the pressure of the fixed platen 42, so that the airtightness detection cannot be performed. The bolster tool 5 can support and limit the side wall between the air inlet duct 21 and the air outlet duct 22 of the workpiece 2, so that the possibility of dumping the workpiece 2 is reduced, and the connection tightness between the workpiece 2 and the table board of the fixed pressing plate 42 and between the workpiece 2 and the table board of the workbench 1 is improved. In the process, the stability of the fixed pressure plate 42 can be improved by the matching of the guide ring 43 and the transmission round rod 45.
Subsequently, the air intake module 3 is activated, and the air pump 31 can generate and store a part of compressed air, which is delivered to the three-way air intake valve 33 through the air intake runner 32. The air pipe 36 can convey compressed air to the detection cavity 12 to detect the air tightness of the workpiece 2. Since the air inlet duct 21 is sealed by the table top of the worktable 1 except the portion connected with the detection cavity 12, and the air outlet duct 22 of the workpiece 2 is sealed by the fixed pressing plate 42, once the leakage point exists on the workpiece 2, the high-pressure air will leak, and the worker can judge the air tightness of the workpiece 2 according to the leakage point.
The detection tube 37 delivers the compressed air to the barometer 38, and the barometer 38 detects the pressure value of the compressed air, so that the worker can start the air pump 31 when the air pressure is too low. Further, if the airtightness of the workpiece 2 is detected, the pressure of the compressed air is continuously reduced, which also means that there is a problem in the airtightness of the workpiece 2.
The compressed air that each workpiece 2 can contain is relatively fixed, and the reading on the gas flow meter 34 should be relatively stable, and if the reading on the gas flow meter 34 becomes larger, this also means that the airtightness of the workpiece 2 is problematic. That is, the gas flow meter 34 can cooperate with the gas pressure meter 38 to further accurately judge the airtightness of the workpiece 2.
When the air supply of the air cylinder 41 is insufficient, the piston rod of the air cylinder 41 is likely to fall rapidly under the action of its own weight and the weight of the fixed pressing plate 42, and when the piston rod of the air cylinder 41 reaches the maximum stroke, a large impact is generated, which is likely to cause damage to the air cylinder 41. And the stopper 47 additionally provided on the driving round bar 45 can be engaged with the stopper groove 44 to limit the maximum falling distance of the piston rod of the pneumatic cylinder 41, so as to reduce the maximum falling speed of the piston rod of the pneumatic cylinder 41, thereby reducing the impact force.
Because the specification of total heat exchange core is various, in order to improve the application scope of this equipment, bolster frock 5 is for dismantling, removable setting. When the bolster tool 5 needs to be replaced, the bolster tool 5 is firstly pulled, the first mounting block 61 is separated from the clamping opening formed by the two second elastic pieces 72, the positioning block 73 is separated from the positioning groove 65, and the whole bolster tool 5 can freely rotate by an angle.
The bolster tool 5 is pulled to enable the first installation block 61 to slide along the first sliding groove 63, the second installation block 62 to slide along the second sliding groove 64, then the bolster tool 5 is rotated to enable the second installation block 62 to rotate out of the second sliding groove 64 and to be transferred into the first sliding groove 63, the bolster tool 5 is pulled again to enable the first installation block 61 and the second installation block 62 to slide along the first sliding groove 63, so that the bolster tool 5 is taken down from the workbench 1, and the bolster tool 5 can be replaced.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
