3) And (3) inflation detection: the air is inflated to the air inlet 12 of the rolling plate through the inflation assembly, the lower platform 4 is driven by the platform driving mechanism to ascend to a set position, the inflation is stopped when the pressure reaches a set value during inflation, then the air tightness test is started, and the next step is carried out when the test is qualified;
in the steps, the action of an inflation joint moves to a set position to be in contact with and sealed with the air inlet 12 of the rolling plate, meanwhile, an inflation valve is opened, inflation reaches a set value within a specific time, if the inflation does not reach the set value, the valve group automatically exhausts air, alarms, is regarded as a non-qualified part, the inflation reaches the set pressure value, stays for the set specific time, records the initial pressure value, detects the pressure value again after the set time, compares the pressure value with the initial value, does not meet the qualified standard, alarms, is regarded as a non-qualified part, if the product is unqualified, the current product needs to be taken out and a new product needs to be assembled again, and the next step of assembly of the base 6 is carried out only when the air tightness of the product is qualified, in the embodiment, the lower platform 4 needs to be driven to continuously ascend with the base 6, the base 6 retracts into the rubber air bag of the air spring 7 for a section when ascending, and the ascending height of the base 6 needs to be set according to the characteristics of the product, thereby the assembly requirement of the product can be better satisfied. The inflation valve and the valve set are all referred to the prior art and are not specifically described herein.
4) Assembling a base 6: the electric wrench 13 is moved to the bottom of the lower platform 4 through the wrench driving mechanism, the base 6 is fixed to the bottom of the air spring 7 through the electric wrench 13, then the electric wrench 13 is moved out through the wrench driving mechanism, and the lower platform 4 is driven to ascend to a set position through the platform driving mechanism;
in the above steps, the electric wrench 13 can respectively realize left-right translation and lifting through the wrench translation cylinder 28 and the wrench lifting cylinder 29, the electric wrench 13 firstly sequentially penetrates the screw 14 through the assembly hole of the lower platform 4 and the base 6, and is connected to the metal bottom plate 22 of the air spring 7 through threads, and then the locking nut 15 is installed at the bottom of the screw 14 and locked at the bottom of the base 6, so that the base 6 can be fixed at the bottom of the air spring 7, and the assembly of the base 6 is realized.
5) Resetting the crimping die: the upper supporting plate 3 and the hemming upper die 8 are driven to move upwards to the setting position by the upper plate driving mechanism, and then the hemming left die 9 and the hemming right die 10 are driven to reset by the left die driving mechanism and the right die driving mechanism respectively;
in the steps, the upper crimping die 8 moves upwards to reset, the left crimping die 9 moves leftwards to reset, the right crimping die 10 moves rightwards to reset, and the product can be conveniently taken out next step after the crimping die resets.
6) Taking out the product: the assembled air spring 7 is removed.
In the steps, the platform 4 is driven by the platform driving mechanism to ascend by a certain height, then the air spring 7 product which is assembled and has good air tightness can be conveniently taken out, and the assembly detection work of the next product can be circularly carried out after the product is taken out.
The fixing manner or the fixing connection manner that is not described in this embodiment may be threaded connection or welding, or other existing connection manners may be adopted according to specific positions, and both threaded connection and welding belong to the prior art, and are not specifically described herein.
The skilled person should understand that: although the present invention has been described according to the above embodiments, the inventive idea is not limited to this embodiment, and any application of the inventive idea is also included in the scope of the present patent right.
