[0024] Water is stored inside the detection pool 201 for air tightness detection of pipe fittings. The pipe fittings to be detected are stacked longitudinally in the temporary storage tank box device 4 above the detection pool 201. The sorting rack device 5 cooperates with the pipe receiving device 6 to realize the directional falling and collection of the pipe fittings. After the pipe receiving device 6 completes the collection and fixation of the pipe fittings, the pipe fittings are rotated and introduced into the water body of the detection pool 201 for air tightness detection. After the detection of a single pipe fitting is completed, it is rotated and reset to the top of the detection pool 201. Under the drive of the first driving member 202, the push rod 203 is driven to move to the side close to the pipe receiving device 6, penetrate the pipe receiving device 6, complete the top movement of the detected pipe fittings, and move the pipe fittings to the side of the guide seat 204 to realize the transfer of the detected pipe fittings.

[0038] exist Figure 1 In this state, the second driving member 501 rotates, and the dropped pipe falls into the top side arc grid 606, which is set in a semicircular groove shape. When the pipe falls into the top side arc grid 606, the fourth driving members 603 on both sides operate to drive the pressing plates 604 on both sides to rotate in opposite directions until they abut against the pipe, completing the pressing and limiting of the pipe, and then the third driving member 601 operates to drive the side plate 602 and the fixed pipe to rotate 180 degrees, so that the fixed pipe is at the bottom side of the detection pool 201 for air tightness detection, and at the same time, the bottom side arc grid 606 rotates to the top to place the next pipe to be detected. The pipe fittings are guided to fall into the arc-shaped grid 606 and fixed.

At this time, the first driving member 202 drives the top rod 203 to move, and the top rod 203 passes through the through groove 605 on one side and abuts against one end of the pipe fitting.

[0040] In one embodiment of the present invention:

[0041] A method for detecting air tightness of tubular castings, the method comprising the following steps: S100, stacking pipes in batches and placing them in a longitudinal groove to wait for single pieces to be led out; S200, driving the pipes to fall piece by piece, and dropping them onto a grid for fixation; S300, rotating the pipes into a detection tank and letting them stand to eliminate bubbles; S400, detecting bubbles and judging the air tightness of the pipes; S500, moving and transporting the detected pipes, and performing a cyclic operation.

[0042] The working principle of the present invention is as follows: water is stored inside the detection pool 201 for air tightness detection of pipe fittings. The pipe fittings to be detected are stacked longitudinally in the temporary storage tank box device 4 above the detection pool 201. The sorting rack device 5 cooperates with the pipe fitting receiving device 6 to achieve directional falling and collection of the pipe fittings. After the pipe fitting receiving device 6 completes the collection and fixation of the pipe fittings, the pipe fittings are rotated and introduced into the water body of the detection pool 201 for air tightness detection. After the detection of a single pipe fitting is completed, it is rotated and reset to the top of the detection pool 201. Driven by the first driving member 202, the top rod 203 is driven to move to the side close to the pipe fitting receiving device 6. , penetrate the pipe receiving device 6, complete the top movement of the detected pipe, and move the pipe to the side of the guide seat 204 to realize the transfer of the detected pipe. Through the guide seat 204, the pipe is directionally transferred. A transfer device (not shown in the figure) can be set on the side of the guide seat 205 away from the first driving member 202 to realize the directional transfer of the pipe. After the pipe to be detected is rotated into the water body, it is left to stand for a certain period of time to eliminate the bubble error generated after the rotation of the pipe. Then the bubble detection member 205 is operated, and the hydrophone can convert the sound signal in the water into an electrical signal. When bubbles are generated, the hydrophone receives the sound pulse generated by the bubbles. By analyzing the acoustic pulses and measuring the frequency range and amplitude of the acoustic pulses, the generation of bubbles can be determined. When bubbles continue to be generated, it can be determined that the air tightness of the pipe is poor. The interior of the longitudinal groove 403 is rectangular, and the internal size is slightly larger than the pipe to be tested. When the pipes to be tested are placed horizontally in batches in the longitudinal groove 403, they are stacked one by one, and the bottom selection rack device 5 can be used to complete the single piece export control of the pipe;

[0043] The bottom pipe of the longitudinal groove 403 is located in the middle of the two dividing plates 502. When the second driving member 501 rotates, it can drive the bottom pipe to fall in a directional manner, and at the same time complete the delivery of the inner pipes of the longitudinal groove 403 one by one. Figure 1In this state, the second driving member 501 rotates, and the dropped pipe falls into the top side arc grid 606, which is set in a semicircular groove shape. When the pipe falls into the top side arc grid 606, the fourth driving members 603 on both sides operate to drive the pressing plates 604 on both sides to rotate in opposite directions until they abut against the pipe, completing the pressing and limiting of the pipe, and then the third driving member 601 operates to drive the side plate 602 and the fixed pipe to rotate 180 degrees, so that the fixed pipe is at the bottom side of the detection pool 201 for air tightness detection, and at the same time, the bottom side arc grid 606 rotates to the top to place the next pipe to be detected. The pipe fittings are guided to fall into the arc-shaped grid 606 and fixed. When the inspection of the pipe fittings inside the water body is completed, the third driving member 601 runs again, driving the pipe fittings to be inspected to rotate 180 degrees, and then the fourth driving member 603 on the top drives the pressing plate 604 to rotate and reset, so that the pressing plate 604 no longer presses and limits the pipe fittings. At this time, the first driving member 202 drives the top rod 203 to move, and the top rod 203 passes through a side groove 605 and abuts against one end of the pipe fitting. The top movement drives the pipe fitting to move to the side of the guide seat 204, thereby realizing the transfer of the inspected pipe fittings, and then repeats the above operation process until the inspection of all pipe fittings is completed.

[0044] In summary, this equipment can realize the automatic detection process of air tightness of pipe fittings. It can place pipe fittings in batches, export them one by one in an orderly manner, accurately position and fix them, put them into the pool to keep them still to ensure the detection accuracy, accurately judge the air tightness based on bubbles, and efficiently transport pipe fittings, which greatly improves the detection efficiency and accuracy and saves manpower.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
