As shown in fig. 1, a detection system 1 according to an exemplary embodiment of the present invention is used for detecting the air tightness and the pipeline direction of a pipeline assembly 2. Specifically, the detection system 1 includes a pipeline running detection device 11 for accommodating the pipeline assembly 2 and an air tightness detection device 12 disposed on both sides of the pipeline running detection device 11. As shown in fig. 2, the detection of the course of the pipeline is performed by placing the pipeline assembly 2 in the pipeline course detection device 11 of the detection system 1. Here, the line course refers to the direction of extension of the line. If the pipeline component 2 to be tested cannot be placed into the pipeline direction detection device 11, the pipeline direction of the pipeline component 2 is unqualified. The airtightness of the piping component 2 is detected by airtightness detection devices 12 provided on both sides of the piping run detection device 11. The utility model discloses a detecting system through move towards the pipeline detection device and the gas tightness detection device is integrated to be in the same place, has improved the efficiency that detects effectively, has reduced manufacturing cost.

The line assembly 2 to be tested is described below. The line assembly 2 has a line 21, a connection head 22 and a sleeve 23 for fixing the line 21 and the connection head 22. The conduit 21 is typically a hose, such as a rubber tube, teflon bellows, or the like. The sleeve 23 can fixedly connect the pipeline 21 to the connector 22 by crimping and ensure the air tightness requirement of the fixed connection. The line run of the line arrangement 2 is not restricted in any way, and the line arrangement 2 can have a connection head 22 and a sleeve 23 at one end, or can have a connection head 22 and a sleeve 23 at both ends.

In the air tightness detection of the pipeline assembly 2, because the connector 22 and the pipeline 21 are in interference fit before the sleeve 23 is buckled, even if the sleeve 23 is not buckled, the air tightness abnormity cannot be identified by 100% in the air tightness leakage detection process, so that defective products are delivered from factories. Thus, in an exemplary embodiment, the detection system 1 of the present invention includes a sleeve error proofing device 13. The sleeve error-proofing device 13 of the detection system 1 is used for performing error-proofing detection on problems that a sleeve is not assembled or buckled and the like possibly occurring in the sleeve, so that a pipeline assembly product with an air tightness defect is prevented from leaving a factory.

Specifically, in an exemplary embodiment, the sleeve 23 has a snap groove 231, and the sleeve error proofing device 13 includes an error proofing member 131 that mates with the snap groove 231. When the sleeve 23 completes the crimping process to form the crimping slot 231, the pipeline assembly can be smoothly mounted on the pipeline direction detection device 11; when the sleeve 23 is not fastened to form the fastening groove 231 for some reason, the error-proofing member 131 interferes with the sleeve which is not fastened, so that the line assembly 2 cannot be mounted on the line direction detection device 11. The sleeve error-proofing device comprises an error-proofing component matched with the buckling groove, so that the assembling error of the sleeve without buckling can be effectively detected, and the pipeline assembly product with the air tightness defect is prevented from leaving a factory.

Specifically, fig. 3B exemplarily shows an operation state of the sleeve error proofing device 131 when the casing 23 is inserted. In this case, the sleeve error-proofing device 13 is matched with the buckling groove 231 formed by the sleeve 23 after completing the buckling process, so as to allow the pipeline assembly to be smoothly accommodated to the pipeline running direction detecting device 11, so that the pipeline assembly can be subjected to subsequent air tightness detection. Fig. 3C exemplarily shows an operation state of the sleeve error proofing device 131 when the unbuckled sleeve 23 is put in. In this case, the sleeve error-proofing device 13 cannot be engaged with the sleeve 23 without the crimping grooves 231, and the error-proofing member 131 interferes with the sleeve which is not crimped, thereby reminding the operator to terminate the subsequent airtightness test and reminding the operator that the tested pipe assembly is not qualified.

In an exemplary embodiment, the pipeline orientation detection device 11 has a pipeline orientation groove G for receiving the pipe assembly 2, and the error protection component 131 extends into the pipeline orientation groove G or is located outside the pipeline orientation groove G. Fig. 3A shows an example in which the error prevention member 131 extends into the pipe run groove G. Alternatively, as shown in fig. 3A, the error prevention member 131 may be configured as a rectangular projection that protrudes toward the inside of the pipe running groove G. After the sleeve is buckled, the diameters of the outer sides of the sleeve are different due to the buckling grooves, and the error-proofing component 131 with the rectangular bump structure is matched with the position (namely the buckling groove) where the diameter of the sleeve is reduced by utilizing the diameter change of the buckled sleeve. If the sleeve is not buckled, the outer diameter of the sleeve does not need a position which is locally reduced, and the pipeline assembly with the sleeve cannot be placed in the pipeline direction detection device due to interference of the rectangular convex blocks. Of course, the error-proofing member 131 may be located outside the pipe running groove G as long as the error-proofing member 131 can interfere with the unbuckled sleeve. Although the error-proofing member of the rectangular bump structure is simple in structure and convenient to install, it is understood that the specific structure of the error-proofing member is not limited to the rectangular bump, and it may be any structure that is matched with the crimping groove.

In an exemplary embodiment, the sleeve error proofing device 13 includes a sleeve detector 132 for detecting whether the sleeve 23 is mounted. Under the condition that the sleeve is not assembled, the pipeline assembly can still be placed into a pipeline trend detection device (a sample plate detection tool), and at the moment, if the air tightness detection is carried out, the sleeve is not assembled wrongly. By providing the sleeve detector 132, the detection of the air tightness can be effectively avoided without assembling the sleeve, thereby ensuring the accuracy of the detection of the air tightness.

As shown in fig. 3A, the sleeve detector 132 may be a metal detection sensor disposed in a through hole in the inner wall of the pipe run channel, the position of the metal detection sensor corresponding to the position of the sleeve of the pipe assembly to be detected. Through installation metal detection sensor, if the sleeve of metal material is not assembled to the pipeline subassembly, the telescopic existence of sensor can not be surveyed, and gas tightness detection device will unable the start-up (can not carry out the work piece leak hunting) this moment to remind operating personnel that the pipeline subassembly that should detect is unqualified. It should be understood that the type of sensor is not limited to a metal detection sensor, as long as it can accurately detect the presence or absence of the sleeve.

Alternatively, the error-proofing member 131 and the cartridge detector 132 of the cartridge error-proofing device 13 may be disposed on both sides of the groove inner wall of the pipe run groove G. In this case, the error-proofing detection of the sleeve being unassembled and the sleeve being unbuckled can be performed simultaneously, and the structural arrangement of such a sleeve error-proofing device is comparatively simple.

In an exemplary embodiment, the air-tightness detecting device 12 may include a detecting head 121 coupled to the pipe assembly 2 along a pipe run of the pipe assembly 2. On the one hand, detect head 121 and can detect the gas tightness of pipeline subassembly 2, on the other hand, detect head 121 and can fix a position the tip of pipeline subassembly 2 according to the loading benchmark. So set up, for detecting the gas tightness and the pipeline moves towards separately going on, saved the pipeline and moved towards the tip setting element on the detection device, consequently the production frock of simplifying, saved cost and space.

Further, in another exemplary embodiment, the airtightness detection apparatus 12 may include a detection head 121 connected to the pipe assembly 2 and a driving mechanism 122 for driving the detection head 121 to reciprocate with respect to the pipe running direction detection apparatus 11. The driving mechanism drives the detection head to be abutted or separated from the pipeline assembly. Of course, in other embodiments, the detection head may be fixed, and the pipeline direction detection device may be configured to reciprocate relative to the detection head.

As shown in fig. 4, in an exemplary embodiment, the driving mechanism 122 may include an operating handle 1221, a link mechanism 1222, and a pushing rod 1223 fixedly connected to the detection head 121, wherein the link mechanism 1222 converts the swinging motion of the operating handle 1221 into the linear motion of the pushing rod 1223. Through swing operating handle, operating personnel can make the catch bar along rectilinear movement, and the catch bar drives and detects head 121 and move on the straight line to the drive detects head and pipeline subassembly looks butt or separation.

Fig. 5A and 5B show a closed state and an opened state of the airtightness detecting apparatus of fig. 4, respectively. The closed state of the air tightness detection device refers to the fact that the air tightness detection device is abutted to the pipeline assembly to be detected, and the loosened state of the air tightness detection device refers to the fact that the air tightness detection device is separated from the pipeline assembly to be detected. As shown in fig. 5A, the operator can rotate the operating handle 1221 clockwise to move the pushing rod 1223 leftwards in a straight line, thereby driving the detecting head 121 to abut against the pipeline assembly to be detected. Accordingly, as shown in fig. 5B, the operator can move the push rod 1223 in a straight line to the right by rotating the operating handle 1221 counterclockwise, thereby driving the detection head 121 to be separated from the pipe assembly to be detected. Alternatively, the swing angle of the operating knob 1221 is substantially 180 °.

In an exemplary embodiment, the driving mechanism 122 further includes a rail 1224 extending in a direction parallel to the push rod 1223 and guiding the reciprocating motion of the detection head 121 in the direction. Through setting up the guide rail, can further ensure the accuracy that detects the head and remove to ensure the location and press from both sides tight to pipeline subassembly.

Alternatively, the detection head may be fixedly provided at an end portion of the guide rail, and the guide rail may be reciprocally moved in a straight line along a predetermined trajectory. For example, as shown in fig. 5A, the detection head is fixed relative to the guide rail, and the guide rail is reciprocally moved along a linear track by the restricting member of the fixing base. Of course, the detection head may be movably disposed on a guide rail extending in a straight line, so that the detection head can be reciprocally moved in a straight line on the straight guide rail.

In an exemplary embodiment, the pipeline direction detecting device 11 may include a sleeve control block 111 and a pipeline control block 112 which are separately provided, and the error preventing part 131 and the sleeve detector 132 are provided in the sleeve control block 111. A plurality of sleeve control blocks 111 and a plurality of pipe control blocks 112 may be separately provided according to the shape and length of the pipe assembly. Therefore, the pipeline trend detection device can be built more flexibly.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
