FIG. 2 shows a top view of a bellows pressure test combination tool according to one embodiment of the present utility model. Fig. 3 shows an assembly schematic of a bellows pressure test combination tool according to an embodiment of the present utility model. As shown in the figure, the bellows pressure test combination tool 100 mainly comprises a tool bottom plate 101, a first L-shaped support plate 102, a second L-shaped support plate 103, a flange joint group and a clamp 105.
The first L-shaped support plate 102 and the second L-shaped support plate 103 are oppositely arranged at two ends of the tool bottom plate 101 in the length direction. The second L-shaped support plate 103 is provided with an air source interface 106.
Referring to fig. 4, the flange joint group includes flange joints 104 of various types for adapting to corrugated pipes 117 of various sizes (pipe diameters D1, D2 … … Dn), improving versatility.

The two ends of the bellows 117 to be tested are fixed in cooperation with the flange joint 104.
Two clips 105 are used to secure the ends of the flange joint 104 and the bellows 117.
It will be readily appreciated that the bellows 117 is disposed between the first L-shaped support plate 102 and the second L-shaped support plate 103 by means of the adapted flange joint 104. And gas is introduced into the gas source interface 106 of the second L-shaped support plate 103 to realize pressure test of the corrugated pipe 117.
Preferably, the first mounting holes 107 are distributed throughout the tooling floor 101. The first L-shaped support plate 102 and the second L-shaped support plate 103 are provided with a second mounting hole 108 and a third mounting hole 109, respectively. The first L-shaped support plate 102 and the second L-shaped support plate 103 are fixed by bolts. The bolts penetrate through the second mounting holes 108 and the first mounting holes 107 and are in threaded fit with the second mounting holes 108 and the first mounting holes 107 to fix the first L-shaped support plate 102. Similarly, the bolt penetrates into the third mounting hole 109 and the first mounting hole 107 and is screwed with the third mounting hole 109 and the first mounting hole 107 to fix the second L-shaped support plate 103. Since the first mounting holes 107 are formed on the tooling bottom plate 101, the specific mounting positions of the first L-shaped support plate 102 and the second L-shaped support plate 103 can be selected to adjust the distance between the two, so as to adapt to the length of the bellows 117. In other words, the tool bottom plate 101 has the function of adjusting the distance between the first L-shaped support plate 102 and the second L-shaped support plate 103, the tool bottom plate 101 does not need to be replaced for the corrugated pipe 117 with a specific length, the assembly process of the corrugated pipe pressure test combined tool 100 is simplified, and the assembly difficulty is reduced.
Preferably, the second mounting hole 108 and the third mounting hole 109 are waist-shaped holes, and the length direction of the second mounting hole is consistent with the length direction of the tool bottom plate 101. The waist-shaped holes are convenient for finely adjusting the distance between the first L-shaped support plate 102 and the second L-shaped support plate 103, and the purpose of adjusting the preset axial compression or stretching amount of the corrugated tube 117 can be achieved.
Preferably, the bellows pressure test combination tool 100 further comprises a pressing device. The pressing device includes a first fixing lever 110 and a second fixing lever 111.

One end of the second fixing rod 111 abuts against a side of the second L-shaped support plate 103 opposite to the flange joint 104. The first fixing rod 110 and the second fixing rod 111 have a bent shape, and the other ends thereof are fixed by being inserted into each other. The pressing device is used for pressing the first L-shaped support plate 102 and the second L-shaped support plate 103 from two sides, and provides clamping force for the first L-shaped support plate 102 and the second L-shaped support plate 103. More preferably, referring to fig. 3, a plurality of first fitting holes 112 are formed at the other end of the first fixing lever 110, and a plurality of second fitting holes 113 are formed at the other end of the second fixing lever 111. The first fixing lever 110 and the second fixing lever 111 are fixed by bolts. The bolts penetrate into the first assembly holes 112 and the second assembly holes 113 and are fixed in a threaded fit with the first assembly holes 112 and the second assembly holes 113. It is easy to understand that, by means of the vertical dislocation between the first assembly hole 112 and the second assembly hole 113, the corresponding insertion depth is adjusted, so that the distance between the first fixing rod 110 and one end of the second fixing rod 111 is adjustable, so as to match the distance adjustment between the first L-shaped support plate 102 and the second L-shaped support plate 103. Because the pressure test needs to check the tightness and pressure resistance of the joint of the corrugated pipe 117 under different working conditions, in general, the test assembly is in a natural state, but the actual use has deformation, the combined tool 100 can predefine the corrugated pipe 117 to a specific deformation amount for tightness check and repeated loading check. The pressing device can adjust the interval (axial rough adjustment) of one ends of the first and second fixing bars 110 and 111 through the assembly positions of the first and second assembly holes 112 and 113, and simultaneously perform axial fine adjustment of the first and second L-shaped support plates 102 and 103 through the waist-shaped holes.

The sealing rings 114 are disposed between the first L-shaped support plate 102 and the flange joint 104 and between the second L-shaped support plate 103 and the flange joint 104, and are used for ensuring the tightness between the first L-shaped support plate 102 and the flange joint 104 and the tightness between the second L-shaped support plate 103 and the flange joint 104. More preferably, the sealing ring 114 is a memory alloy C-shaped metal sealing ring, and plastic deformation after use under low temperature condition can be eliminated by heating to the shape recovery temperature, so that the sealing ring can be reused and waste is avoided.
Preferably, referring to fig. 1 and 3, the bellows pressure test combination tool 100 further includes an air source pressurizing device 115 and a connecting line 116. One end of the connecting pipeline 116 is connected to the air source interface 106 on the second L-shaped support plate 103, and the other end is connected to the air source pressurizing device 115. The gas source pressurizing device 115 drives gas into the bellows 117 through the connecting line 116 for testing. It should be noted that, one end of the second fixing rod 111 of the pressing device is a hollow structure, and is used for avoiding the connection pipeline 116 to be connected to the air source interface 106 on the second L-shaped support plate 103.
Preferably, the bellows pressure test combination tool 100 further includes a pressure sensor (not shown). A pressure sensor may be provided on the connection line 116 for monitoring the sealing and pressure resistance of the bellows 117 joint.
The following describes in detail the assembly process and the testing process of the bellows pressure test combination tool 100 according to the present utility model with reference to all the drawings.
The first L-shaped support plate 102 and the second L-shaped support plate 103 are connected to the tooling bottom plate 101 by bolts according to the length of the bellows 117. The flange joint 104, the sealing ring 114 and the clamp 105 are selected to match the joint size of the bellows 117 to be tested. The interval between one ends of the first fixing rod 110 and the second fixing rod 111 of the compressing device is adjusted, and the other ends of the two are fixed through bolts.
Then, the air source pressurizing device 115 and the connecting line 116 are connected to conduct a sealing performance and a pressure measurement test.
When the size of the tested air bellows 117 joint changes, the flange joint 104 and the memory alloy C-shaped metal sealing ring with corresponding sizes are replaced, and corresponding clamps are selected (according to requirements). When the working condition of the tested air bellows 117 changes, the bellows 117 can be preset to a specific deformation, the axial rough adjustment is carried out through the pressing device, and the axial fine adjustment is carried out through the waist-shaped holes of the L-shaped support plate, so that the purpose of adjusting the axial compression or stretching quantity of the bellows 117 is achieved.
The bellows pressure test combination tool provided by the utility model has the beneficial effects of strong universality, diversified test working conditions, strong assemblability and convenience in operation.
It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present utility model without departing from the spirit and scope of the utility model.
