[0026] Reference Figure 1-3 As shown, an aluminum-cased explosion-proof pressure test structure includes:

[0027] Frame 1, on which a positioning station is provided;

[0028] A positioning mechanism is provided at a positioning station. The positioning mechanism includes a positioning fixture 4 and two positioning frames 3. The two positioning frames 3 are arranged opposite to each other at the positioning station. The positioning frames 3 are used to position the positioning fixture 4, which is clamped with an aluminum shell 5.

[0029] The testing mechanism 2 is located above the positioning mechanism. The testing mechanism 2 is positioned opposite to one of the two positioning frames 3. The opening of the aluminum shell 5 is positioned opposite to the testing mechanism 2. The testing mechanism 2 is used to perform an explosion-proof pressure test on the aluminum shell 5 on the positioning fixture 4.

[0030] The unloading mechanism 6 is located above the positioning station. The unloading mechanism 6 is positioned opposite to the other positioning frame 3 of the two positioning frames 3. The bottom of the aluminum shell 5 is positioned opposite to the unloading mechanism 6. The unloading mechanism 6 is used to strike the bottom of the aluminum shell 5 to disengage it from the positioning fixture 4.

[0031] This utility model uses a positioning frame 3 at the testing mechanism 2 to position the positioning fixture 4, which holds the aluminum shell 5. The testing mechanism 2 then performs an explosion-proof pressure test on the aluminum shell 5. The positioning fixture 4 is then flipped and placed on the positioning frame 3 at the unloading mechanism 6. The unloading mechanism 6 taps the bottom of the aluminum shell 5 to disengage it from the positioning fixture 4. The entire process of fixing and testing the aluminum shell 5 is convenient and quick, achieving the goal of convenient testing of the aluminum shell 5. Using the positioning fixture 4 to hold the aluminum shell 5 prevents it from scattering when it bursts, achieving a good protective effect. This utility model is simple to manufacture and use, and has good performance.

[0032] In one embodiment of this utility model, the testing mechanism 2 includes a testing frame 21, on which a lifting driver 22 is provided. The lifting driver 22 is driven to connect with a testing plate 23. A testing head 24 is provided on the testing plate 23. An opening 25 is provided on the testing head 24. The lifting driver 22 drives the testing head 24 to be inserted into the opening of the aluminum shell 5 so that the opening 25 is located inside the aluminum shell 5. The test medium is injected through the opening 25 to test the explosion-proof pressure of the aluminum shell 5.

[0033] Specifically, the lifting driver 22 drives the test head 24 to be inserted into the opening of the aluminum shell 5 so that the opening 25 is set inside the aluminum shell 5. Water, oil, air and other test media are injected through the opening 25 to test the explosion-proof pressure of the aluminum shell 5 until the explosion-proof texture at the bottom of the aluminum shell 5 is broken. The explosion-proof pressure of the aluminum shell 5 is recorded. The degree of automation is high and the detection efficiency is high.

[0034] In one embodiment of the present invention, the test head 24 has a conical structure, at least one opening 25 is provided on the outer side wall of the test head 24, and a test interface 26 is provided on the test head 24. The test interface 26 and the opening 25 are connected through a test channel 27.

[0035] Specifically, the test head 24 has a conical structure, which allows it to better fit the opening of the aluminum shell 5, making it suitable for testing aluminum shells 5 of different diameters and with a wide range of applications. The outer wall of the test head 24 is provided with at least one or more openings 25. Multiple openings 25 can increase the liquid inlet speed and improve the testing efficiency.

[0036] In one embodiment of the present invention, the unloading mechanism 6 includes an unloading frame, on which an unloading cylinder 61 is provided. The unloading cylinder 61 is driven to be connected to a push rod 62. The push rod 62 is disposed opposite to the aluminum shell 5 on the positioning fixture 4. The unloading cylinder 61 drives the push rod 62 to push the bottom of the aluminum shell 5 so that the aluminum shell 5 is disengaged from the positioning fixture 4.

[0037] Specifically, the feeding cylinder 61 drives the push rod 62 to push the bottom of the aluminum shell 5, causing the aluminum shell 5 to detach from the positioning fixture 4, thereby completing the feeding of the aluminum shell 5. This facilitates the feeding of the aluminum shell 5 and ensures feeding efficiency.

[0038] In one embodiment of the present invention, the push rod 62 includes a rod body 63, a sliding cavity is provided on the rod body 63, a guide rod 64 passes through the sliding cavity, and a compression spring is provided between the sliding cavity and the guide rod 64.

[0039] Specifically, a guide rod 64 is inserted into the sliding cavity, and a compression spring is provided between the sliding cavity and the guide rod 64, so that the push rod 62 forms a spring rod structure, which can buffer the push rod 62, avoid hard contact with the feeding cylinder 61, and improve its service life.

[0040] In one embodiment of the present invention, a pusher block 65 is provided at the free end of the pusher rod 62, and an avoidance chamber 66 is provided on the pusher block 65. The outer diameter of the pusher block 65 is smaller than the outer diameter of the aluminum shell 5.

[0041] Specifically, after the explosion-proof texture at the bottom of the aluminum shell 5 is broken, its bottom will protrude. The pusher block 65 is provided with a clearance chamber 66 that can cover the bottom of the aluminum shell 5 to avoid insufficient contact with the bottom of the aluminum shell 5, which would cause the pusher block to fail. The outer diameter of the pusher block 65 is smaller than the outer diameter of the aluminum shell 5, so that the edge of the pusher block 65 pushes the material against the bottom of the aluminum shell 5, ensuring the accuracy of the pusher block.

[0042] In one embodiment of this utility model, the positioning fixture 4 includes a fixed plate 41 and a movable plate 42. The fixed plate 41 is provided with guide rods 43 at both ends, and the movable plate 42 is slidably mounted on the guide rods 43. Both the fixed plate 41 and the movable plate 42 are provided with clamping grooves 44. The clamping grooves 44 on the fixed plate 41 and the movable plate 42 form a clamping structure 45 for clamping and positioning the aluminum shell 5. The free end of the guide rod 43 is connected to a driving component. The driving component is used to move the movable plate 42 toward the fixed plate 41 to clamp the aluminum shell 5 on the clamping structure 45.

[0043] Specifically, the clamping grooves 44 on the fixed plate 41 and the moving plate 42 form a clamping structure 45 for clamping and positioning the aluminum shell 5. The driving component is used to move the moving plate 42 toward the fixed plate 41 to clamp the aluminum shell 5 onto the clamping structure 45, thereby achieving rapid clamping of the aluminum shell 5 and improving clamping efficiency.

[0044] In one embodiment of this utility model, the driving component includes a support plate 46, which is connected to a guide rod 43. The support plate 46 has a mounting groove, and a rotating shaft 47 is provided on the mounting groove. An eccentric wheel 48 is provided on the rotating shaft 47. A spring 492 is sleeved on the guide rod 43. One end of the spring 492 is connected to a fixed plate 41, and the other end is connected to a moving plate 42. The spring 492 drives the moving plate 42 to abut against the eccentric wheel 48.

[0045] Specifically, the aluminum shell 5 to be tested is placed with its opening facing upwards on the clamping structure 45 formed by the clamping groove 44 on the fixed plate 41 and the moving plate 42. The handle 491 on the eccentric wheel 48 is pulled, causing the eccentric wheel 48 to rotate. At the same time, the moving plate 42 is pushed towards the fixed plate 41 under the drive of the eccentric wheel 48 until the connecting plane 49 on the eccentric wheel 48 abuts against the moving plate 42. At the same time, the spring 492 between the moving plate 42 and the fixed plate 41 is compressed. Under the reaction force of the spring 492, the moving plate 42 is pushed away from the fixed plate 41 under the drive of the eccentric wheel 48, so that a gap appears in the clamping structure 45 to release the aluminum shell 5. The eccentric wheel 48 and the moving plate 42 can be linked to achieve rapid clamping of the aluminum shell 5 and improve clamping efficiency.

[0046] In one embodiment of the present invention, the protruding end of the eccentric wheel 48 is provided with a connecting plane 49, the eccentric wheel 48 is provided with a handle 491, the handle 491 is provided with anti-slip texture, and the handle 491 and the connecting plane 49 are symmetrically arranged on both sides of the eccentric wheel 48.

[0047] Specifically, pulling the handle 491 on the eccentric wheel 48 causes the eccentric wheel 48 to rotate. Simultaneously, driven by the eccentric wheel 48, the moving plate 42 is pushed towards the fixed plate 41 until the connecting plane 49 on the eccentric wheel 48 abuts against the moving plate 42. At the same time, the spring 492 between the moving plate 42 and the fixed plate 41 is compressed. Pushing the handle 491 upward or downward causes the moving plate 42 to move away from the fixed plate 41 under the reaction force of the spring 492. The handle 491 not only facilitates the lifting and moving of the positioning fixture 4, but also facilitates the rotation of the eccentric wheel 48. It is easy to use. The contact between the connecting plane 49 on the eccentric wheel 48 and the moving plate 42 ensures that the moving plate 42 and the fixed plate 41 are in a stable state, preventing the moving plate 42 from shaking and affecting the clamping effect on the aluminum shell 5.

[0048] In one embodiment of this utility model, the positioning frame 3 includes two frames 31, and guide blocks 32 are provided on the two frames 31. Guide grooves 33 are provided on the guide blocks 32. The guide grooves 33 on the two guide blocks 32 form a moving channel 34 that facilitates the sliding of the positioning fixture 4. Limiting blocks 35 are provided on the guide grooves 33. Magnets 36 are provided on the limiting blocks 35. The positioning fixture 4 is magnetically connected to the magnets 36 on the limiting blocks 35.

[0049] Specifically, the positioning fixture 4 is slid along the moving channel 34 formed by the guide grooves 33 on the two guide blocks 32 to the limiting block 35. The positioning fixture 4 is magnetically connected to the magnet 36 on the limiting block 35, so that the positioning fixture 4 can quickly move to the test position. The moving channel 34 can position the positioning fixture 4 in the up, down, left, and right directions. The magnetic connection between the positioning fixture 4 and the magnet 36 on the limiting block 35 can limit the positioning fixture 4 in the front and back. At the same time, the magnetic connection can ensure the test stability of the positioning fixture 4. The structure is simple and reasonable. The moving channel 34 can position positioning fixtures 4 of the same size and can be adapted to clamp various aluminum shell 5 specifications of positioning fixtures 4.

[0050] Usage process

[0051] The aluminum shell 5 to be tested is placed with its opening facing upwards on the clamping structure 45 formed by the clamping grooves 44 on the fixed plate 41 and the moving plate 42. The handle 491 on the eccentric wheel 48 is pulled, causing the eccentric wheel 48 to rotate. Simultaneously, the moving plate 42 is pushed towards the fixed plate 41 by the eccentric wheel 48 until the connecting plane 49 on the eccentric wheel 48 abuts against the moving plate 42. At the same time, the spring 492 between the moving plate 42 and the fixed plate 41 is compressed, causing the positioning fixture 4 to slide along the moving channel 34 formed by the guide grooves 33 on the two guide blocks 32 to the limiting block 35. The positioning fixture 4 is magnetically connected to the magnet 36 on the limiting block 35. The lifting driver 22 drives the test head 24 to be inserted into the opening of the aluminum shell 5, so that the opening 25 is set inside the aluminum shell 5. Through the opening 25, the test head 24 is inserted. The explosion-proof pressure of the aluminum shell 5 is tested by immersing it in test media such as water, oil, and air until the explosion-proof grooves on the bottom of the aluminum shell 5 are broken. The explosion-proof pressure of the aluminum shell 5 is recorded. Then, the positioning fixture 4, which is loaded with the aluminum shell 5 that has completed the explosion-proof test, is removed from the positioning frame 3 and rotated 180° so that the bottom of the aluminum shell 5 is facing upward. The positioning fixture 4 is then placed on the positioning frame 3 at the unloading mechanism 6. The handle 491 is pushed upward or downward. Under the reaction force of the spring 492, the eccentric wheel 48 pushes the moving plate 42 away from the fixed plate 41, so that the clamping structure 45 has a gap and the aluminum shell 5 is released. The unloading cylinder 61 drives the push rod 62 to push the bottom of the aluminum shell 5, so that the aluminum shell 5 is detached from the positioning fixture 4. This completes the explosion-proof pressure test of the aluminum shell 5.
