DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 6 As shown, a sealing detection device for a new energy vehicle workpiece 19 of the present invention, the workpiece 19 has a plurality of through holes 20 in the vertical direction, and the outer contour of the workpiece 19 has a plurality of corners 21, the sealing detection device comprises: a workbench 1, on which a fixed seat 2 is arranged, and the fixed seat 2 has a cavity 3 for placing the workpiece 19; a first sealing assembly 4, which has a first sealing member 5 and a slider 6, the first sealing member 5 surrounds the cavity 3, the first sealing member 5 has a contracted state and an expanded state in the cavity 3, a plurality of sliders 6 are movably arranged in the fixed seat 2, the slider 6 is used to squeeze the first sealing member 5, the first sealing member 5 can be in an expanded state, and can be movably abutted against the workpiece 19 in the cavity 3 and undergo elastic deformation, so as to seal the workpiece 19, and because the slider 6 squeezes it, it undergoes elastic deformation again, so as to be pressed against the corner 21; a second sealing assembly 7, which has a plurality of second sealing members 8 movably arranged above the fixed seat 2, the second sealing members 8 are respectively movably abutted against the through holes 20, so as to seal the through holes 20.

[0033] During operation, the first seal 5 is first placed in a contracted state, and then the workpiece 19 is placed in the cavity 3 on the fixed seat 2. At this time, the sliders 6 in the fixed seat 2 are respectively in relative positions with the corners 21 on the outer contour of the workpiece 19. Subsequently, the first seal 5 is converted from a contracted state to an expanded state to closely fit the outer surface of the workpiece 19 and undergo elastic deformation. Since the outer contour of the workpiece 19 has several corners 21, wrinkles may appear at the portion where the first seal 5 fits the corners 21. To ensure that the corners 21 on the workpiece 19 can fit closely with the first seal 5, the first sealing assembly 4 drives the slider 6 to abut against the first seal 5 in the expanded state and squeeze the first seal 5, so that the first seal 5 undergoes further elastic deformation. Even if there are wrinkles on the part where the first seal 5 fits the corner 21, it will be flattened due to the squeezing of the slider 6, thereby ensuring that the first seal 5 fits tightly against the corner 21. At the same time, the second sealing assembly 7 drives the second seal 8 to press against the through hole 20 on the workpiece 19 to achieve sealing of the through hole 20. In this way, the outer contour and the through hole 20 of the workpiece 19 are sealed, and the corner 21 on the workpiece 19 also fits tightly against the first seal 5, and there will be no inadequate sealing or air leakage, so it will not affect the sealing performance test of the workpiece 19; wherein, the first seal 5 is preferably an airbag, which is a flexible rubber capsule filled with compressed air or water medium, and uses the compressibility of air and the fluidity of water to achieve elasticity.

[0034] The first seal 5 is connected to the gas source and has a channel for gas to enter. The first seal 5 can be in an expanded state due to inflation and return to a contracted state due to deflation. Before the detection begins, the first seal 5 is in a contracted state. When the workpiece 19 is placed in the cavity 3 on the fixed seat 2, gas is supplied to the first seal 5 to make it expand. This expanded state enables the first seal 5 to fit tightly against the outer surface of the workpiece 19 to form a good seal. After the detection is completed, the gas is discharged from the first seal 5 to return to the contracted state, so that the workpiece 19 can be easily removed from the fixed seat 2.

[0035] The first sealing component 4 also includes a first driving member 9. A plurality of first driving members 9 are arranged on the fixed seat 2. The output ends of the first driving members 9 are connected to sliders 6. The first driving members 9 are used to drive the sliders 6 to slide. When the workpiece 19 is placed in the cavity 3, the sliders 6 in the fixed seat 2 are respectively in relative positions with the corners 21 on the outer contour of the workpiece 19. Subsequently, the first sealing member 5 is converted from a contracted state to an expanded state. To ensure that the first sealing member 5 is tightly fitted with the corners 21 on the workpiece 19, the first driving member 9 is started to drive the sliders 6 to squeeze the first sealing member 5. The first driving member 9 can be a cylinder, a motor or an electromagnet.

[0036] Specifically, a plurality of pressure strips 10 are disposed on the fixing seat 2 , and the pressure strips 10 are connected end to end and surround the edge of the side wall of the cavity 3 .

[0037] In order to provide sealing between the pressure strips 10, a third sealing member 11 is provided between adjacent pressure strips 10, and the two sides of the third sealing member 11 are in close contact with the ends of the two pressure strips 10 respectively, thereby effectively preventing gas leakage from the gaps between the pressure strips 10, thereby enhancing the sealing performance of the entire device.

[0038] In order to fix the first seal 5 on the fixing seat 2, the pressure strip 10 and the inner wall of the cavity 3 jointly form a sealing groove 12, and the first seal 5 is provided with a clamping part 13 on both sides, and the clamping part 13 is clamped in the sealing groove 12. The sealing groove 12 formed between the pressure strip 10 and the inner wall of the cavity 3 provides an embedding position for the first seal 5, and the clamping parts 13 on both sides of the first seal 5 can be inserted into the sealing groove 12, so that the first seal 5 is stably fixed on the fixing seat 2, and a good sealing effect is also ensured.

[0039] Specifically, the second sealing assembly 7 also includes: a support seat 14, which is arranged above the fixed seat 2; a second driving member 15, and a plurality of second driving members 15 are obliquely arranged on the support seat 14, and the second sealing member 8 is connected to the output end of the second driving member 15. The second driving member 15 drives the second sealing member 8 to press against the through hole 20 on the workpiece 19 to achieve sealing of the through hole 20. The second driving member 15 can be a cylinder, a motor or an electromagnet.

[0042] The steps for sealing the workpiece 19 by the sealing detection device in this scheme are as follows: first, the workpiece 19 is placed in the cavity, and then the third driving member 18 is started, driving the moving seat 17 to descend, and the support seat 14 connected to the moving seat 17 is descended accordingly, so that the fixed rod 16 and the second driving member 15 arranged on the support seat 14 are synchronously close to the workpiece 19 until the fixed rod 16 abuts against the workpiece 19, at which time, the second driving member 15 and the second sealing member 8 arranged at its output end are located above the workpiece 19; then, the first sealing member 5 is converted from a contracted state to an expanded state, abuts against the workpiece 19 and undergoes elastic deformation; the first driving member 9 is started, driving the slider 6 to squeeze the first sealing member 5, so that the first sealing member 5 undergoes elastic deformation again and fits tightly with the corner 21 on the outer contour of the workpiece 19; at the same time, the second driving member 15 drives the second sealing member 8 to approach and fit tightly to the through hole 20 on the workpiece 19, thereby achieving the sealing of the through hole 20, and at this point, the sealing of the workpiece 19 is completed.
