as shown in fig. 4, the air charging assembly 4 comprises an air cylinder 41 fixedly installed on the box 1, the air cylinder 41 is communicated with an external air source, a platform 43 is installed at the output end of the air cylinder 41, a second sliding block 42 is arranged at the bottom of the platform 43, a sliding rail 11 matched with the second sliding block 42 is arranged on the box 1, the sliding rail 11 is arranged along the length direction of the air bag tube 6, and thus the platform 43 can slide on the sliding rail 11 to approach or separate from the detection part 2 under the driving of the air cylinder 41;
as shown in fig. 4-5, a plurality of groups of inflation units 7 are arranged on the platform 43, and the plurality of groups of inflation units 7 are in one-to-one correspondence with the plurality of groups of first plug holes on the detection block 23 so as to be used for inflating the plurality of groups of air bag tubes 6;
the inflation unit 7 includes a tailstock 71 fixed at one end of the platform 43, the tailstock 71 is fixed at a position at a side far away from the air bag tube 6, a guide rod 72 is slidably arranged on the tailstock 71, the guide rod 72 is also arranged along the length direction of the air bag tube 6, so that the guide rod 72 can slide in the tailstock 71 along the length direction of the air bag tube 6, meanwhile, an inflation seat 77 is fixedly arranged at one end of the guide rod 72 far away from the tailstock 71, and a second spring 73 is arranged between the inflation seat 77 and the tailstock 71, and the second spring 73 is sleeved in the guide rod 72, so that the inflation seat 77 can be driven to move together while the guide rod 72 slides, and acting force is generated on the second spring 73;
in order to make the sliding of the inflatable seat 77 smoother, a slideway (not shown in the figure) is arranged on the platform 43, and a sliding table (not shown in the figure) matched with the sliding is arranged at the bottom of the inflatable seat 77, so that the sliding of the inflatable seat 77 is guided by the cooperation of the slideway and the sliding table;
a connecting seat 74 is fixed at one end of the inflatable seat 77, which is close to the guide rod 72, a through hole 741 is arranged in the connecting seat 74, the through hole 741 is arranged along the length direction of the air bag tube 6, one end of the through hole 741, which is close to the guide rod 72, is communicated with the output end of the pump body 5, and one end of the through hole 741, which is far away from the guide rod 72, is communicated with an air tube 75;
a shell 76 is fixed at one end, far away from the guide rod 72, of the inflatable seat 77, a second plug hole is formed in the shell 76, the second plug hole and the first plug hole are coaxially arranged, and the second plug hole is communicated with one end, far away from the through hole 741, of the air pipe 75, so that air can be pumped into the second plug hole through the through hole 741 and the air pipe 75 through the pump body 5, and meanwhile, the second plug hole is in conical arrangement, namely, the inner diameter of the second plug hole is gradually reduced along the direction that the air bag pipe 6 is inserted into the shell 76, so that the sealed plug of the air bag pipe 6 with different diameters can be adapted;
in summary, when the ventilation amount of the air bag tube 6 needs to be detected, firstly, one end of the air bag tube 6 is inserted into the first insertion hole on the detection block 23, and then the air cylinder 41 is controlled to extend, so as to drive the platform 43 to approach to the direction of the detection block 23;
along with the movement of the platform 43, the inflation unit 7 arranged on the platform 43 simultaneously moves towards the direction of the detection block 23, because the second plug hole and the first plug hole are arranged coaxially, one end of the air bag tube 6 away from the first plug hole can enter the second plug hole;
because the second insertion hole is tapered, as the cylinder 41 continues to extend until the air bag tube 6 cannot continue to be inserted into the second insertion hole, the position is where the air bag tube 6 is in sealing contact with the second insertion hole;
the rear cylinder 41 continues to extend in the above state, and at this time, the air bag tube 6 generates an acting force on the second insertion hole, and the acting force is transmitted to the air inflation seat 77 through the housing 76, so that the air inflation seat 77 is driven to move toward the tailstock 71, and the second spring 73 is compressed;
in this embodiment, the position sensor may be provided to collect the relative position of the inflation seat 77 and the platform 43, so as to determine whether the air bag tube 6 is inserted into the sealing contact position, that is, when the position of the inflation seat 77 and the platform 43 are relatively moved during detection, it is indicated that the air bag tube 6 is inserted into the sealing contact position, or the pressure sensor may be provided between the second spring 73 and the tailstock 71, and when the pressure value is collected by the pressure sensor, it may also be determined that the air bag tube 6 is inserted into the sealing contact position, where the above two methods are only commonly used methods for determining the position, and as other possible manners, are not limited herein;
when the air bag pipe 6 is inserted into the sealing contact position, the air cylinder 41 stops extending, the pump body 5 is started at the moment, constant-pressure air is pumped into the air bag pipe 6 through the through hole 741, the air pipe 75 and the second insertion hole, the ventilation total amount in a certain time is collected through the ventilation tester, so that the ventilation speed of the air bag pipe 6 is determined, and the ventilation speed value is compared with the value in design to determine whether the air bag pipe 6 is qualified or not;
after the detection is completed, the pump body 5 is closed, the cylinder 41 starts to retract and return to the initial position, the detected air bag tube 6 is removed, the air bag tube 6 which is not detected is assembled, and a new round of detection is started.
In order to realize the control of each electrical component during the detection of the air bag tube 6, in this embodiment, a PLC control system is provided, and the PLC control system is electrically connected to the air cylinder 41, the pump body 5 and the pressure sensor, and the PLC control system controls the cooperative work of the air cylinder 41, the pump body 5 and the pressure sensor to complete the detection operation of the air bag tube 6.
In the detection process of the air bag tube 6, because the second insertion hole is in a conical shape, the air bag tube 6 has a certain fault tolerance when the second insertion hole Kong Shiyou is inserted, but when the air bag tube 6 is longer, one end of the air bag tube 6 close to the air inflation assembly 4 still has a sagging risk, so that the air bag tube 6 and the second insertion hole are in butt joint dislocation, in order to solve the problem, as shown in fig. 1, an adjusting assembly 3 is arranged between the detection part 2 and the air inflation assembly 4, and the adjusting assembly 3 is used for supporting the air bag tube 6;
as shown in fig. 3, the adjusting assembly 3 includes at least two groups of adjusting units, which are respectively denoted as a first adjusting unit and a second adjusting unit, wherein the first adjusting unit is located near one end of the detecting portion 2, and the second adjusting unit is located near one end of the inflating assembly 4, so that the two groups of adjusting units support the air bag tube 6 more fully, and in this embodiment, any group of adjusting units may be additionally arranged between the first adjusting unit and the second adjusting unit, so that the support to the air bag tube 6 is more stable;
because the structures of the adjusting units of each group are the same, the following description is given by taking the first adjusting unit as an example:
the first adjusting unit comprises a first sliding block 31 which is arranged on the sliding rail 11 in a sliding way, a supporting seat 32 is fixedly arranged on the first sliding block 31, a plurality of groups of placing grooves 321 are arranged on the supporting seat 32, and the placing grooves 321 are in one-to-one correspondence with the first inserting holes (or the second inserting holes) and are used for supporting the air bag pipe 6;
therefore, the airbag tube 6 is supported by the first adjusting unit and the second adjusting unit, so that the airbag tube 6 is smoother when being abutted with the second inserting hole.
For balloon tubes 6 of different diameters or for balloon tubes 6 of different lengths, the elongated length of the cylinder 41 is different when the balloon tube 6 reaches a position in sealing contact with the second socket hole, because the second adjustment unit is located close to the inflation assembly 4, so that when the elongated length of the cylinder 41 is too long, the inflation assembly 4 interferes with the second adjustment unit, thereby affecting detection;
in order to avoid this problem, as shown in fig. 3, the first adjusting units are fixedly arranged, and a first spring 33 is arranged between two adjacent adjusting units, and the elasticity of the first spring 33 is far smaller than that of the second spring 73, so that when the air charging assembly 4 moves to a position interfering with the adjusting units along with the air cylinder 41, the adjusting units are pushed to move on the sliding rail 11 to avoid, and when the air charging assembly 4 is reset, the adjusting units are reset under the driving of the first spring 33.
In the third embodiment, in order to realize automatic detection of the air bag pipe 6, a PLC control system needs to be configured to coordinate operation of all electric elements, however, the PLC control system has a certain difficulty in operation, has higher requirements on quality of personnel, and increases the cost of enterprises to a certain extent;
the embodiment specifically illustrates that the complex function of the PLC control system can be realized by a simple control mode, and related structures are as follows:
as shown in fig. 7 to 8, the air pipe 75 is fixedly inserted into the inside of the housing 76 while the end of the air pipe 75 inserted into the housing 76 is closed, and a plurality of groups of air holes 751 communicating with the inner cavity of the air pipe 75 are formed on the outer circle of the inserted portion of the air pipe 75, so that the air inputted from the pump body 5 can be outputted through the air holes 751 without being outputted through the end of the air pipe 75;
an air cavity 761 is arranged at a position corresponding to the position of the air holes 751 in the shell 76, a plurality of groups of air holes 751 are positioned in the air cavity 761 so as to guide the air output by the pump body 5 into the air cavity 761, meanwhile, a first connector 710 and a second connector 711 communicated with the air cavity 761 are arranged at different positions on the shell 76, and the first connector 710 and the second connector 711 can guide the air in the air cavity 761 out;

in the present embodiment, the first valve body 51 and the second valve body 52 can be switched according to different states, so that the first joint 710 (the second joint 711) is connected to or disconnected from the first connection terminal 411 (the second connection terminal 412);
as shown in fig. 7 to 8, an internal thread 763 is provided in the outer casing 76 at the middle position of the second insertion hole and the air cavity 761, an intermediate casing 79 is screwed in the position of the internal thread 763, a through cavity 791 is provided in the interior of the intermediate casing 79, an inner casing 78 is provided in sliding manner in the cavity 791, the inner casing 78 is in sealing sliding connection with the cavity 791, the sliding direction is the direction approaching or separating from the air pipe 75, and a fourth spring 762 is fixedly installed between the inner casing 78 and the air cavity 761, and the fourth spring 762 is used for providing power for resetting of the inner casing 78;
as shown in fig. 6, the inner shell 78 is provided with a taper hole 781 which is inserted into the balloon tube 6, and the inner diameter of the taper hole 781 is gradually reduced along the direction of inserting the balloon tube 6, so that the sealing insertion of the balloon tubes 6 with different diameters can be adapted;
a tube plug 782 is arranged at one end of the taper hole 781 close to the air bag tube 6, and a horn mouth 783 communicated with the taper hole 781 is arranged on the tube plug 782, and the horn mouth 783 can enable the air bag tube 6 to be better guided into the taper hole 781;
as shown in fig. 8, a stepped hole 786 is provided at an end of the inner case 78 near the air tube 75, the stepped hole 786 has an inner diameter smaller than the minimum inner diameter of the tapered hole 781, while the stepped hole 786 communicates with the tapered hole 781, and the inner diameter of the stepped hole 786 is adapted to the outer diameter of the air tube 75 so that the air tube 75 can be inserted into the stepped hole 786;
a valve plate 784 is slidably disposed in the tapered hole 781, the diameter of the valve plate 784 is matched with the minimum inner diameter of the tapered hole 781, and a third spring 785 is fixedly installed between the valve plate 784 and the stepped hole 786, and the third spring 785 tightens the valve plate 784 on the step of the stepped hole 786 in an initial state, that is, the valve plate 784 is located at the minimum diameter of the tapered hole 781, so that the valve plate 784 can seal the tapered hole 781;
in this embodiment, the detection of the air bag tube 6 is divided into four steps, which correspond to four different states, namely an initial state, an insertion state, a ventilation state and a separation state, wherein the initial state is a non-ventilation detection state of the air inflation unit 7, the insertion state is a process of the air bag tube 6 before the ventilation detection after the air inflation unit 7 is ventilated, the ventilation state is a state of the air bag tube 6 for ventilation detection, and the reset state is a process of the air inflation unit 7 returning to the initial state, and the four states are described in detail below:
initial state: in this state, as shown in fig. 10, the inner case 78 is positioned inside the intermediate case 79 by the fourth spring 762, and the valve plate 784 is positioned at the minimum diameter of the tapered hole 781 by the third spring 785, so that the valve plate 784 can seal the tapered hole 781 while the position of the air hole 751 is positioned inside the air chamber 761.
Plug-in state: in this state, as shown in fig. 11, first, one end of the air bag tube 6 is inserted into the first insertion hole on the detection block 23, then the pump body 5 is opened, and the gas outputted from the pump body 5 enters the air tube 75 through the through hole 741 on the connection seat 74 and is outputted from the air hole 751 on the air tube 75, and the step is the same as the embodiment;
at this time, the first joint 710 communicates with the first connection terminal 411 through the first valve body 51, the second joint 711 is disconnected from the second connection terminal 412 through the second valve body 52, and the second connection terminal 412 communicates with the outside atmosphere through the second valve body 52, and the switching process is synchronously completed by setting a switching switch;
so that the gas outputted from the pump body 5 is introduced into the air chamber 761 through the air hole 751, and the gas introduced into the air chamber 761 can enter the air cylinder 41 through the connecting pipeline between the first connector 710 and the first connecting end 411, thereby pushing the output end of the air cylinder 41 to extend;
because the tension of the third spring 785 is large, the gas entering the air cavity 761 cannot push the valve plate 784, so that the sealing between the valve plate 784 and the taper hole 781 cannot be released, and the gas can only be output through the first connector 710 to push the air cylinder 41 to extend;
in the process of extending the air cylinder 41, the air charging unit 7 is driven to move towards the direction of the detection block 23, because the taper hole 781 and the first inserting hole are coaxially arranged, one end of the air bag tube 6 away from the first inserting hole can enter the taper hole 781, and along with the continuous extension of the air cylinder 41, the air bag tube 6 cannot be continuously inserted into the taper hole 781, and the position is the position where the air bag tube 6 is in sealing contact with the taper hole 781;
the rear cylinder 41 continues to extend in the above state, and at this time, the air bag tube 6 is in a position in sealing contact with the tapered hole 781, so that the air bag tube 6 cannot move relative to the inner casing 78, and further, as the cylinder 41 extends, the air bag tube 6 generates a force on the tapered hole 781, and the force drives the inner casing 78 to slide in the middle casing 79 in the direction of the air pipe 75, and compresses the fourth spring 762;
as the inner housing 78 slides, the stepped bore 786 in the inner housing 78 gradually approaches the air tube 75 because the stepped bore 786 matches the outer diameter of the air tube 75, such that as the inner housing 78 slides, the air tube 75 slowly enters the stepped bore 786, and as the air tube 75 enters the stepped bore 786, the air hole 751 portion of the air tube 75 also slowly enters the stepped bore 786;
as the air tube 75 extends into, the front end of the air tube 75 enters the taper hole 781 of the inner shell 78 and pushes the valve plate 784 open, so that the valve plate 784 moves away from the sealing position of the taper hole 781, and the air tube 75 can ventilate the air bag tube 6 through the taper hole 781, so that ventilation amount detection of the air bag tube 6 is facilitated;
when the valve plate 784 is pushed up by the air pipe 75, one end of the inner casing 78 far away from the air bag tube 6 just abuts against the side wall of the air cavity 761, so that the air cavity 761 is divided into two parts which are isolated from each other, namely a first part and a second part, wherein the first part is positioned inside the inner casing 78, the first part isolates the air pipe 75, the second part is positioned outside the inner casing 78, and the second part is communicated with the first joint 710 or the second joint 711, so that the air output from the air pipe 75 cannot be input into the air cylinder 41 through the first joint 710, and the air cylinder 41 stops extending at the moment;
in the present embodiment, for convenience of explanation, it is set that the elastic force of the second spring 73 is much larger than that of the fourth spring 762, so that the second spring 73 is not deformed in the plugging state, and thus the housing 76 keeps moving synchronously with respect to the platform 43 and the output end of the air cylinder 41.
Ventilation state: in this state, as shown in fig. 12, the gas is outputted through the pump body 5, and the airbag tube 6 is ventilated through the gas pipe 75, the gas hole 751 and the taper hole 781, so that the ventilation amount of the airbag tube 6 is detected, the total ventilation amount in a certain time is collected by the ventilation amount tester, so that the ventilation speed of the airbag tube 6 is determined, and then the ventilation speed value is compared with the value at the time of design to determine whether the airbag tube 6 is qualified or not;
in this embodiment, the plugging state and the ventilation state are switched naturally, and no special pressure sensor is required to be independently provided to determine whether to plug in or not.
Disengagement state: in this state, as shown in fig. 13, the second joint 711 is communicated with the second connection end 412 through the second valve body 52, while the first joint 710 is disconnected from the first connection end 411 through the first valve body 51, and the first connection end 411 is communicated with the outside atmosphere through the first valve body 51, and the switching process is accomplished in synchronization by setting a switch;
for convenience of explanation, the chamber in which the cylinder 41 is connected to the first connection end 411 is set as a first chamber, and the chamber in which the cylinder 41 is connected to the second connection end 412 is set as a second chamber;
in the initial state of switching, because the fourth spring 762 is in a compressed state, an acting force is generated on the outer shell 76 and the inner shell 78 at the same time, the inner shell 78 can not move because of being propped against the air bag tube 6, the outer shell 76 and the output end of the air cylinder 41 can keep synchronous movement, and because the first connecting end 411 is communicated with the outside atmosphere through the first valve body 51, the air in the first chamber can be discharged from the first connecting end 411, and the output end of the air cylinder 41 can retract under the drive of the fourth spring 762 until the fourth spring 762 returns to the initial state;
when the fourth spring 762 is restored to the original state, the end of the inner housing 78 away from the air bag tube 6 is separated from the side wall of the air cavity 761, and at this time, the air tube 75 is also separated from the inside of the taper hole 781 of the inner housing 78, and no longer abuts against the valve plate 784, so that the valve plate 784 returns to the sealing position against the taper hole 781;
at the same time, the air hole 751 on the air tube 75 is in communication with the air cavity 761 again, and at this time, the air output by the pump body 5 enters the second cavity through the air hole 751, via the second joint 711, the second valve body 52 and the second connecting end 412, so as to push the output end of the air cylinder 41 to retract continuously until the air cylinder returns to the initial position, and at this time, the air bag tube 6 can be taken out;
at this time, the device can be switched to an initial state by a change-over switch so as to facilitate the next detection.
Therefore, the automatic state switching in the detection process of the air bag pipe 6 can be realized through simple switching operation, so that the operation difficulty is reduced, the maintenance is convenient, the cost of enterprises is reduced, and the method has certain popularization value.
