[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses an explosion-proof hydrant testing mechanism.

[0024] Reference Figure 1 The explosion-proof nut testing mechanism includes a base 1, a feeding device 2 for conveying finished explosion-proof nut 38 on the base 1, a receiving device 3 for receiving finished explosion-proof nut 38 at the output end of the feeding device 2, a testing device 4 for testing the air permeability of finished explosion-proof nut 38 on the base 1, and a conveying device 5 for conveying finished explosion-proof nut 38 from the receiving device 3 to the testing device 4 on the base 1. The feeding device 2 includes a vibrating plate 6 on one side of the base 1, and several finished explosion-proof nut 38 are sequentially mounted on the vibrating plate 6 for conveying.

[0025] Therefore, the assembled explosion-proof hydrant finished product 38 is conveyed by the feeding device 2, and the receiving device 3 is used to receive the explosion-proof hydrant finished product 38 from the output end of the feeding device 2. The conveying device 5 is activated to transport the explosion-proof hydrant finished product 38 from the receiving device 3 to the detection device 4. Subsequently, the detection device 4 is activated to test the flow rate of the explosion-proof hydrant finished product 38, thereby realizing the detection of the explosion-proof hydrant finished product 38. The receiving device 3 and the conveying device 5 realize the fully automatic feeding of the explosion-proof hydrant finished product 38, saving labor costs, time and effort, reducing the possibility of the explosion-proof hydrant finished product 38 being placed upside down due to manual feeding, and reducing the safety hazards of manual handling by operators, thereby improving the detection efficiency of the explosion-proof hydrant finished product 38.

[0026] Reference Figure 1 and Figure 2 The receiving device 3 includes a mounting frame 7 mounted on a base 1. A first servo module 8 is mounted on the mounting frame 7. A placement plate 9 is bolted to the slide of the first servo module 8. The surface of the placement plate 9 facing away from the base 1 has several placement slots 10 that match the size of the finished explosion-proof bolts 38. The placement slots 10 are connected to the output end of the vibratory feeder 6, and the finished explosion-proof bolts 38 are respectively placed in the placement slots 10. In this embodiment, four placement slots 10 are used as an example, meaning that the placement plate 9 can receive four finished explosion-proof bolts 38 at a time.

[0027] Therefore, the assembled explosion-proof bolt finished product 38 is conveyed by the vibratory feeder 6, the first servo module 8 is started, and the slide table and the placement plate 9 of the first servo module 8 are moved synchronously. The explosion-proof bolt finished product 38 at the output end of the vibratory feeder 6 are sequentially placed in the four placement slots 10 of the placement plate 9.

[0028] Reference Figure 1 and Figure 3The conveying device 5 includes a support frame 11 bolted to the base 1. A horizontally arranged first telescopic cylinder 12 is installed on the support frame 11. A first sliding frame 13 is installed at the output end of the first telescopic cylinder 12. A vertically arranged first lifting cylinder 14 is bolted to the first sliding frame 13. A first conveying frame 15 is installed at the output end of the first lifting cylinder 14. A plurality of first gripper cylinders 16 are installed on the first conveying frame 15. The gripping ends of the plurality of first gripper cylinders 16 correspond to a plurality of placement slots 10 respectively. In this embodiment, the number of first gripper cylinders 16 is set to four, and the distance between adjacent first gripper cylinders 16 is equal to the distance between adjacent placement slots 10. The support frame 11 is bolted to a guide rail 17 that is horizontally arranged with the first telescopic cylinder 12. A slider 18 that matches the size of the guide rail 17 is slidably connected to the guide rail 17. The first sliding frame 13 is set on the slider 18. The guide rail 17 limits the movement direction of the slider 18, thereby improving the stability of the slider 18 and the first sliding frame 13 during the sliding process.

[0029] Therefore, the first telescopic cylinder 12 is activated, causing the first sliding frame 13 at the output end of the first telescopic cylinder 12 to slide along the guide rail 17. When the output ends of the four first gripper cylinders 16 are on the same straight line in the vertical direction of the four placement slots 10, the first lifting cylinder 14 is activated, causing the first transport frame 15 at the output end of the first lifting cylinder 14 to descend. The four first gripper cylinders 16 are activated to grip the four explosion-proof bolt finished products 38. Then, the first lifting cylinder 14 is activated, causing the first transport frame 15 to rise. The first telescopic cylinder 12 is activated, causing the first sliding frame 13 to slide to the detection device 4.

[0030] Reference Figure 1 and Figure 4 The detection device 4 includes a turntable 19 rotatably connected to a base 1. A drive unit for driving the turntable 19 to rotate is provided on the base 1. The drive unit includes a cam divider 26 mounted on the base 1, and the turntable 19 is located at the output end of the cam divider 26. In this embodiment, the cam divider 26 is specifically a four-section cam divider 26. Therefore, activating the cam divider 26 drives the turntable 19 at its output end to rotate. In this embodiment, the rotation direction of the turntable 19 is clockwise.

[0031] Reference Figure 1 and Figure 4The turntable 19 is equipped with several tooling units for fixing the finished explosion-proof bolts 38, and the base 1 is equipped with a detection unit for detecting the finished explosion-proof bolts 38 on the tooling units. In this embodiment, the number of tooling units is set to four, and the four tooling units are evenly distributed along the circumference of the turntable 19. The finished explosion-proof bolts 38, which are transported by the first gripper cylinder 16, are mounted in the tooling units. Each of the four tooling units includes a positioning plate 20 mounted on the turntable 19. The positioning plate 20 is bolted with four positioning seats 21. Each of the four positioning seats 21 has a positioning groove 22 that matches the size of the finished explosion-proof bolts 38. The four finished explosion-proof bolts 38 are respectively mounted in the four positioning grooves 22. The positioning grooves 22 limit the position of the finished explosion-proof bolts 38, reduce the possibility of positional deviation of the finished explosion-proof bolts 38, and improve the stability of the placement of the finished explosion-proof bolts 38.

[0032] Reference Figure 1 and Figure 4 A mounting plate 27 is bolted to the cam divider 26. A turntable 19 is located between the mounting plate 27 and the base 1. A fixing bracket 28 is bolted to the mounting plate 27. Four second lifting cylinders 29 are mounted on the fixing bracket 28. Each of the four second lifting cylinders 29 has a stop block 30 mounted at its output end. The distance between adjacent stop blocks 30 is equal to the distance between adjacent positioning grooves 22. The stop blocks 30 can be made of rubber. Therefore, when the explosion-proof bolt finished product 38 moves between the stop block 30 and the base 1, the second lifting cylinder 29 is activated, causing the stop blocks 30 at the output end of the second lifting cylinder 29 to press down, pressing the explosion-proof bolt finished product 38 firmly between the stop block 30 and the bottom of the positioning groove 22, further improving the stability of the explosion-proof bolt finished product 38 mounted in the positioning groove 22. If no explosion-proof bolt product 38 is placed in the positioning groove 22, the downward pressure height of the block 30 without explosion-proof bolt product 38 will be greater than the downward pressure height of the block 30 with explosion-proof bolt product 38. Thus, the control end can determine the presence or absence of explosion-proof bolt product 38 in the positioning seat 21 based on the downward pressure height of the block 30 at the output end of the second lifting cylinder 29.

[0033] Reference Figure 1 and Figure 4The detection unit includes a measuring frame 23 mounted on a base 1. Four second telescopic cylinders 24 are installed on the measuring frame 23. Measuring blocks 25 are respectively installed at the output ends of the four second telescopic cylinders 24. The distance between adjacent measuring blocks 25 is equal to the distance between adjacent positioning slots 22. An airflow channel is provided inside the measuring block 25, and the airflow channel is connected to an inflation device via a pipe. A flow meter for detecting the air pressure inside the pipe is installed between the inflation device and the measuring block 25. Ventilation holes are provided at the bottom of the positioning slots 22. Therefore, when the explosion-proof bolt finished product 38 moves between the measuring block 25 and the base 1, the second telescopic cylinder 24 is activated, causing the measuring block 25 at the output end of the second telescopic cylinder 24 to press down. The explosion-proof bolt finished product 38 is pressed against the air outlet of the airflow channel and the bottom of the positioning groove 22. The inflation device is activated to inflate the airflow channel through the pipeline. The gas flow rate is controlled at 4L / min. The explosion-proof stone itself is permeable. Some of the airflow passes through the explosion-proof stone of the explosion-proof bolt finished product 38 and is discharged through the vent. Then, the air pressure in the pipeline is measured by the flow meter. The flow meter detection time lasts for 2 seconds. When the measured air pressure of the flow meter fluctuates within the range of 10 to 26 mbar, it is a qualified product. Otherwise, it is an unqualified product if it exceeds this range.

[0034] Reference Figure 1 and Figure 5 A feeding rack 31, opposite to the fixed frame 28, is mounted on the mounting plate 27. A second servo module 32 is mounted on the feeding rack 31. A second sliding frame 33 is mounted on the slide table of the second servo module 32. A third lifting cylinder 34 is bolted to the second sliding frame 33. A second transport frame 35 is bolted to the output end of the third lifting cylinder 34. Four second gripper cylinders 36 are mounted on the second transport frame 35. The gripping ends of the four second gripper cylinders 36 correspond to several positioning slots 22 respectively. In this embodiment, the number of second gripper cylinders 36 is set to four, and the distance between adjacent second gripper cylinders 36 is equal to the distance between adjacent positioning slots 22. A feeding bucket 37 is provided on the base 1. The feeding bucket 37 is located between the third servo module and the base 1. In this embodiment, the number of feeding buckets 37 is set to two, and the two feeding buckets 37 are arranged side by side. One feeding bucket 37 is a qualified product bucket and the other is a defective product bucket.

[0035] Therefore, when it is necessary to unload the finished explosion-proof bolts 38 after inspection, the second servo module 32 is activated, which drives the slide table and the second sliding frame 33 of the second servo module 32 to move synchronously. When the output ends of the four second gripper cylinders 36 are on the same straight line in the vertical direction of the four positioning slots 22, the third lifting cylinder 34 is activated, which drives the second transport frame 35 at the output end of the third lifting cylinder 34 to descend. The second gripper cylinders 36 are activated to grip the four finished explosion-proof bolts 38. Then the third lifting cylinder 34 is activated, which drives the second transport frame 35 to rise. The second servo module 32 is activated, which drives the second sliding frame 33 to slide to the top of the unloading cylinder, unloading qualified products into the qualified product barrel and unqualified products into the unqualified product barrel.

[0036] The implementation principle of this application embodiment is as follows: The assembled explosion-proof bolt finished product 38 is conveyed by the vibratory feeder 6. The first servo module 8 is started, which drives the slide table and the placement plate 9 of the first servo module 8 to slide synchronously. The explosion-proof bolt finished product 38 at the output end of the vibratory feeder 6 is sequentially placed in the four placement slots 10 of the placement plate 9. The first telescopic cylinder 12 is started, which drives the first sliding frame 13 at the output end of the first telescopic cylinder 12 to slide along the guide rail 17. When the output ends of the four first gripper cylinders 16 are on the same straight line in the vertical direction of the four placement slots 10, the first lifting cylinder 14 is started, which drives the first transport frame 15 at the output end of the first lifting cylinder 14 to descend. The four first gripper cylinders 16 are started to grip the four explosion-proof bolt finished products 38. Then the first lifting cylinder 14 is started, which drives the first transport frame 15 to rise. The first telescopic cylinder 12 is started, which drives the first sliding frame 13 to slide to the top of the tooling unit of the turntable 19.

[0037] The cam divider 26 is activated, causing the turntable 19 at its output end to rotate. In this embodiment, the turntable 19 rotates clockwise. When the explosion-proof bolt product 38 on the turntable 19 moves between the abutment block 30 and the base 1, the second lifting cylinder 29 is activated, causing the abutment block 30 at its output end to press down, pressing the explosion-proof bolt product 38 firmly between the abutment block 30 and the bottom of the positioning groove 22, further improving the stability of the explosion-proof bolt product 38 mounted in the positioning groove 22. If no explosion-proof bolt product 38 is placed in the positioning groove 22, the pressing height of the abutment block 30 without the explosion-proof bolt product 38 will be greater than the pressing height of the abutment block 30 with the explosion-proof bolt product 38. Therefore, the control end can determine the presence or absence of the explosion-proof bolt product 38 in the positioning seat 21 based on the pressing height of the abutment block 30 at the output end of the second lifting cylinder 29.

[0038] When the explosion-proof bolt finished product 38 on the turntable 19 moves between the measuring block 25 and the base 1, the second telescopic cylinder 24 is activated, which drives the measuring block 25 at the output end of the second telescopic cylinder 24 to press down. The explosion-proof bolt finished product 38 is pressed against the air outlet end of the airflow channel and the bottom of the positioning groove 22. The inflation device is activated to inflate the airflow channel through the pipeline. The gas flow rate is controlled at 4L / min. The explosion-proof stone itself is permeable. The air pressure in the pipeline is measured by the flow meter. The flow meter detection time lasts for 2 seconds. When the measured air pressure of the flow meter fluctuates within 10-26mbar, it is a qualified product. Otherwise, it is an unqualified product if it exceeds this range.

[0039] When it is necessary to unload the finished explosion-proof bolts 38 after inspection, the finished explosion-proof bolts 38 on the turntable 19 move between the second servo module 32 and the base 1. The second servo module 32 is activated, which drives the slide table and the second sliding frame 33 of the second servo module 32 to move synchronously. When the output ends of the four second gripper cylinders 36 are on the same straight line in the vertical direction of the four positioning slots 22, the third lifting cylinder 34 is activated, which drives the second transport frame 35 at the output end of the third lifting cylinder 34 to descend. The second gripper cylinders 36 are activated to grip the four finished explosion-proof bolts 38. Then the third lifting cylinder 34 is activated, which drives the second transport frame 35 to rise. The second servo module 32 is activated, which drives the second sliding frame 33 to slide to the top of the unloading cylinder, unloading qualified products into the qualified product bin and unqualified products into the unqualified product bin.
