[0002] Aluminum parts include aluminum alloy doors and windows, aluminum foil, aluminum containers, aluminum wires in cables and wires, etc. Aluminum containers such as aluminum pots, aluminum basins, aluminum cups, aluminum bottles, etc. have good thermal conductivity and can heat food quickly. At the same time, aluminum is light and easy to carry and use.

[0003] Aluminum containers need to be quality inspected after production is completed, and the integrity of aluminum containers is one of the quality standards of aluminum containers. The integrity of aluminum containers refers to the fact that there will be no leakage after the aluminum containers are filled with liquid. In order to detect this quality indicator, the aluminum containers need to be poured with test liquids in sequence before leaving the factory. In the process of filling the liquid in the aluminum container, it is necessary to observe whether the outer wall of the aluminum container is leaking liquid. At the same time, it is also necessary to observe whether the liquid level in the aluminum container drops, so as to determine whether the aluminum container meets the quality standards. In addition, after completing the quality inspection of the aluminum container, the liquid in the aluminum container needs to be poured out. The method of pouring and pouring liquid into the aluminum container to detect aluminum leakage is inefficient. In addition, for some cases with small leakage, it is not easy to observe liquid leakage on the outer wall of the aluminum container and changes in the liquid level inside, resulting in poor accuracy in aluminum quality inspection.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figures 1 to 5 As shown, the present invention includes the following embodiments:

[0026] Embodiment 1: A quality inspection device for aluminum parts, comprising a base 1 and a bracket 11 fixedly connected to the upper surface of the base 1; the bracket 11 is in an inverted L shape; the upper end of the bracket 11 extends to the top of the base 1; the upper end of the bracket 11 is vertically penetrated by and fixedly connected to a hydraulic cylinder 12; the upper surface of the base 1 is fixedly connected to a detection pool 2; the detection pool 2 extends along the length direction of the base 1; the detection pool 2 is filled with a detection liquid; the detection liquid flows in the detection pool 2 along the length direction of the detection pool 2; the hydraulic cylinder 12 is located just above the detection pool 2; the lower end of the hydraulic cylinder 12 is fixedly connected to a connecting plate 3; the lower surface of the connecting plate 3 is connected to a detection rod 4; the spacing between adjacent detection rods 4 is adapted to the spacing between the centers of adjacent aluminum parts; the front position of the pool mouth of the detection pool 2 is fixedly connected to a control motor 5; the output shaft of the control motor 5 is fixedly connected to an interception rod 51; the interception rod 51 can be horizontally intercepted just above the detection pool 2 under the drive of the control motor 5.

[0027] Two limit bars 21 are provided at the upper inner side of the detection pool 2; one of the limit bars 21 is provided close to the front side of the detection pool 2, and the other limit bar 21 is provided close to the rear side of the detection pool 2; the limit bar 21 is fixedly connected to the inner wall of the detection pool 2 through an electric push rod 22; the two limit bars 21 approach or move away from each other under the action of their respective electric push rods 22; the end of the limit bar 21 is fixedly connected to a guide bar 23; the end of the guide bar 23 away from the limit bar 21 extends in a direction away from the detection pool 2.

[0028] An adjustment groove 31 is provided on the lower surface of the connecting plate 3; the adjustment groove 31 is slidably connected to the adjustment block 32 along the length direction of the detection pool 2; the upper end of the detection rod 4 is fixedly connected to the lower surface of the adjustment block 32; the lower surface of the adjustment block 32 is penetrated and threadedly connected with an adjustment bolt 33.

[0029] Specifically, after the staff pours the recycled detection liquid into the detection pool 2, the detection liquid in the detection pool 2 will flow along the length direction of the detection pool 2. Figure 1 In the middle, the detection pool 2 flows from right to left. The detection pool 2 is relatively long. After the aluminum container, i.e., the aluminum part, is placed inside the detection pool 2 from the right side of the detection pool 2 after manufacturing and processing, the control motor 5 drives the interception rod 51 to be lowered and placed horizontally above the detection pool 2. The aluminum container gathers around the interception rod 51 as the detection liquid in the detection pool 2 flows, and then drives the electric push rod 22 to drive the respective limit bars 21 to move. The limit bar 21 at the rear moves forward, and the limit bar 21 at the front moves backward. The two limit bars 21 move closer to each other until the distance between the two limit bars 21 is adapted to the front and rear width of the aluminum container.

[0030] After the limit strip 21 is adjusted, the staff will loosen the adjusting bolt 33. After loosening, the adjusting bolt 33 will be out of contact with the bottom of the adjusting groove 31. After loosening, the adjusting bolt 33 will unlock the adjusting block 32 in the adjusting groove 31. Then the staff will control the adjusting block 32 to move along the length direction in the adjusting groove 31. The aluminum containers in the detection pool 2 are adjacent to each other and arranged along the length direction of the detection pool 2. The adjusting block 32 drives the detection rod 4 to move to the top of the corresponding aluminum container center. The adjusting bolt 33 is tightened. The adjusting bolt 33 will press against the bottom of the adjusting groove 31 during the tightening process to lock the adjusting block 32. In this way, the adjustment of the detection rod 4 and the limit strip 21 is completed, so that the detection equipment can perform quality inspection on aluminum containers of different specifications.

[0031] The aluminum container moves from right to left along the detection pool 2 and enters between the two limit bars 21 under the guidance of the guide bar 23. The aluminum container in the limit bar 21 is intercepted by the interception rod 51. Then the hydraulic cylinder 12 will extend and drive the connecting plate 3 to move downward. During the downward movement of the connecting plate 3, multiple detection rods 4 will be driven downward. During the downward movement of the detection rods 4, the detection rods 4 will be inserted into the inner side of the corresponding aluminum container, thereby driving the corresponding aluminum container downward through the downward movement of the detection rods 4. During the downward movement of the aluminum container, it will move toward the bottom of the detection pool 2. During the downward movement of multiple aluminum containers, the detection liquid will enter the detection liquid. When the detection liquid does not exceed the upper port of the aluminum container to be detected, the multiple aluminum containers will move downward to the limit position. For some unqualified aluminum containers with pores, the detection liquid will pass through the pores and enter the inner side of the aluminum container, while for some qualified aluminum containers, the detection liquid cannot enter the inner side of the aluminum container.

[0032] After the aluminum container is immersed in the detection liquid and kept for a period of time, the hydraulic cylinder 12 will shorten and drive the connecting plate 3 to move upward. During the upward movement of the connecting plate 3, multiple detection rods 4 will move upward. During the upward movement of the detection rods 4, the aluminum container will move upward under the action of buoyancy. After the lower end of the detection rod 4 is higher than the upper end of the aluminum container, the control motor 5 drives the interception rod 51 to lift. After the detection, the aluminum container will pass the interception rod 51 and move to the left under the flow of the detection liquid. Then the interception rod 51 is lowered again, and the aluminum container to be detected enters between the two limit strips 21 along the guide strip 23. This is repeated. The staff will observe the inner side of the aluminum container removed from between the two limit strips 21. If the detection liquid is found on the inside of the aluminum container, it means that the aluminum container has a leakage point and is an unqualified product. Otherwise, it means that the quality of the aluminum part is qualified.

[0033] The present invention controls the detection rod 4 to be inserted into the aluminum container and controls the aluminum container to be pressed into the flowing detection liquid, so as to quickly determine whether the aluminum container has a leakage point, and then quickly realize the quality judgment of the aluminum parts. Compared with the existing liquid filling judgment method, the present invention has higher detection efficiency and greater convenience.

[0034] Embodiment 2: The detection rod 4 is fixedly connected to the clamping seat 6 at the lower end; the lower surface of the clamping seat 6 is conical; a driving groove 61 is arranged inside the clamping seat 6; the driving plate 7 is movably connected to the driving groove 61 up and down; the upper surface of the driving plate 7 and the driving groove 61 are abutted against the first spring 71 by the upper groove wall; the center of the lower surface of the driving plate 7 is fixedly connected to the driving member 8; the driving member 8 passes through the clamping seat 6 downward and extends to the outside; the driving plate 7 divides the driving groove 61 into an upper cavity 62 and a lower cavity 63; a clamping groove 64 is horizontally arranged at the upper position of the outer wall of the clamping seat 6; a clamping strip 66 is slidably connected to the clamping groove 64; a plurality of clamping grooves 64 are evenly distributed around the center of the clamping seat 6; the bottom of the clamping groove 64 is connected to the upper cavity 62 through the upper hole 65; the upper cavity 62 is filled with liquid.

[0035] The outer wall of the clamping seat 6 is provided with a vertical bar 9 corresponding to the clamping bar 66; the vertical bar 9 is provided with a vertical groove 91 on the side close to the clamping seat 6; the end of the clamping bar 66 away from the center of the clamping seat 6 is slidably connected in the vertical groove 91; the end of the vertical bar 9 away from the center of the clamping seat 6 is connected to the lower inner wall of the vertical groove 91 through a second spring 92.

[0036] The driving member 8 includes an upper sleeve 81 and a lower rod 82; the upper end of the upper sleeve 81 is fixedly connected to the lower surface of the driving plate 7; the inner and outer walls of the lower end of the upper sleeve 81 are penetrated by a threaded hole 83; the inner thread of the threaded hole 83 is connected to a locking bolt 84; the upper end of the lower rod 82 is movably connected to the inner side of the lower end of the upper sleeve 81.

[0037] Different types of aluminum containers require different clamping positions on their inner walls. Therefore, before leak detection of the aluminum container, the clamping position is adjusted first, specifically, the locking bolt 84 is loosened. After being loosened, the locking bolt 84 is released from contact with the lower rod 82, so that the lower rod 82 is unlocked, and the lower rod 82 moves inside the upper sleeve 81. When the lower rod 82 is away from the driving plate 7, the length of the driving member 8 increases. When the lower rod 82 is close to the driving plate 7, the length of the driving member 8 decreases. When the driving member 8 increases, the upper position of the inner side of the aluminum container to be detected is clamped. When the driving member 8 is shortened, the lower position of the inner side of the aluminum container to be detected is clamped. In this way, different clamping requirements are met.

[0038] After the adjustment of the clamping position is completed, the intercepting rod 51 is lowered, and the aluminum container to be tested is controlled to enter between the two limit bars 21 along with the flow of the testing liquid. The aluminum container to be tested will move to the right below the corresponding testing rod 4, and then the hydraulic cylinder 12 is controlled to extend to drive the connecting plate 3 to move downward. During the downward movement of the connecting plate 3, the multiple adjustment blocks 32 and the testing rod 4 will be driven downward. The multiple testing rods 4 will drive their respective clamping seats 6 to move downward. During the downward movement of the clamping seat 6, the driving member 8 will be driven downward. During the downward movement of the driving member 8, the lower end of the driving member 8 will be driven to contact the inner bottom wall of the aluminum container.

[0039] The driving member 8 needs to overcome the buoyancy of the aluminum container in order to continue to move downward. In this way, the downward movement speed of the driving member 8 will be lower than the downward movement speed of the clamping seat 6. The driving member 8 will drive the driving plate 7 to move upward relatively in the driving groove 61. The driving plate 7 will squeeze the liquid in the upper cavity 62, so that the liquid in the upper cavity 62 will enter the clamping groove 64 along the upper hole 65, thereby pushing the clamping bar 66 to extend out of the clamping groove 64. In the process of the clamping bar 66 moving away from the center of the clamping seat 6, the vertical bar 9 will be driven away from the center of the clamping seat 6. After the vertical bar 9 expands outward, it will abut against the inner wall of the aluminum container. Under the push of the vertical bar 9 and the clamping bar 66, the center of the aluminum container will coincide with the center of the detection rod 4. In this way, as the clamping seat 6 continues to move downward, the pressure applied by the clamping bar 66 to the inner wall of the aluminum container through the vertical bar 9 increases, thereby achieving the clamping of the aluminum container.

[0040] Under the action of the vertical bar 9, the clamping range of the clamping bar 66 on the aluminum container is expanded, making the clamping of the aluminum container more stable, and the clamping range of the aluminum container is expanded to achieve better support for the inner wall of the aluminum container, avoiding deformation caused by the squeeze of the external liquid during the detection process. When the vertical bar 9 contacts the inner wall of the aluminum container but is not clamped, the downward movement of the clamping seat 6 will drive the clamping bar 66 and the vertical groove 91 on the vertical bar 9 to move, so that the contact position between the vertical bar 9 and the inner wall of the aluminum container is not changed and further clamping is achieved, thereby avoiding the vertical bar 9 from scratching the inner wall of the aluminum container during the downward movement of the clamping seat 6, thereby protecting the aluminum container during the detection process. In order to further improve the protection effect, an elastic member of rubber material can be set on the side of the vertical bar 9 away from the clamping seat 6; after the aluminum container is clamped, the aluminum container can enter the detection liquid stably with the opening facing upward, avoiding the situation where the aluminum container rolls over during the downward movement and affects the detection, making the aluminum part detection more stable and smooth;

[0041] After the aluminum container is moved downward, the hydraulic cylinder 12 will shorten and drive the detection rod 4 to move upward, the clamping seat 6 will move upward, and the driving member 8 will move back to its original position under the elastic force of the first spring 71. The first spring 71 pushes the driving plate 7 away from the detection rod 4, so that a negative pressure is formed in the upper cavity 62. The liquid in the clamping groove 64 will flow into the upper cavity 62 along the upper hole 65, and the clamping bar 66 will retract into the corresponding clamping groove 64. The multiple vertical bars 9 will shrink toward the center of the clamping seat 6 as the clamping bar 66 moves. The second spring 92 will also drive the clamping bar 66 to reset in the vertical groove 91.

[0042] Embodiment 3: The upper surface of the driving plate 7 is rotatably connected to the annular strip 73 via the annular groove 72; the first spring 71 is fixedly connected to the upper groove wall of the driving groove 61 at the upper end, and is fixedly connected to the annular strip 73 at the lower end; the cross-sections of the driving plate 7 and the driving groove 61 are circular; the groove wall of the driving groove 61 is provided with a spiral groove 67; the movable seal in the spiral groove 67 is connected to the movable block 68; the movable block 68 is fixedly connected to the outer wall of the driving plate 7.

[0043] The driving groove 61 is provided with a lower hole 69 at the center of the lower inner wall; the driving member 8 passes through the lower hole 69 ; and a gap is formed between the outer wall of the driving member 8 and the inner wall of the lower hole 69 .

[0044] After the aluminum container moves to the detection position, the detection rod 4 will drive the clamping seat 6 and the driving member 8 to move downward. During the downward movement of the driving member 8, it will contact the bottom wall of the aluminum container. The driving member 8 will be suppressed by the buoyancy of the aluminum container to suppress the downward movement speed. The continuous downward movement of the clamping seat 6 will make the driving plate 7 move close to the detection rod 4. The driving plate 7 will drive the movable block 68 to move in the spiral groove 67, so that the driving plate 7 will rotate during the process of approaching the detection rod 4. Since the upper surface of the driving plate 7 is provided with an annular groove 72, and the annular groove 72 is rotatably connected with the annular bar 73, the provision of the first spring 71 does not affect the movement of the driving plate 7. During the rotation of the driving plate 7, the driving member 8 will be driven to rotate. During the rotation of the driving member 8, the aluminum container will be driven to rotate by friction. The rotation of the aluminum container will disturb the surrounding detection liquid, making the surrounding detection liquid more active, making it easier for the detection liquid to pass through the unqualified aluminum container;

[0045] As the clamping seat 6 moves downward, the outside air will enter the lower cavity 63 along the lower hole 69, and finally the clamping strip 66 will be pressed against the inner wall of the aluminum container to achieve clamping. As the aluminum container is immersed in the detection liquid and the detection is completed, the detection rod 4 and the clamping seat 6 will move up. After the clamping seat 6 is away from the inner bottom wall of the aluminum container, the clamping strip 66 releases the clamping of the inner wall of the aluminum container. As the clamping seat 6 continues to move upward, the first spring 71 will push the driving plate 7 away from the detection rod 4, and the driving plate 7 will drive the movable block 68 to move along the spiral groove 67, so that the driving plate 7 will rotate in the process of moving away from the detection rod 4. The rotating driving plate 7 will drive the driving member 8 to rotate. The driving member 8 can be provided with a rubber protrusion at the lower end to increase the friction with the inner bottom wall of the aluminum container.

[0046] The rotating driving member 8 will drive the aluminum container to rotate. During the rotation of the aluminum container, the detection liquid flowing into the inside will flow in the direction away from the driving member 8 under the action of centrifugal force. The inner bottom wall of the aluminum container vacates space to form a water-free area during rotation, and the detection liquid on the driving member 8 is also thrown away. In addition, in the process of the driving plate 7 moving away from the detection rod 4, the gas in the lower chamber 63 will be discharged along the lower hole 69, and the lower hole 69 will blow the water stains on the surface of the driving member 8 to accelerate the throwing out of the residual detection liquid on the driving member 8. Finally, the driving member 8 moves up and out of the aluminum container. Since the water stains on the surface of the detection member are thrown away, the detection error of the next aluminum container to be tested is reduced, and excessive residual water stains can be avoided to affect the detection accuracy, thereby improving the quality detection accuracy of aluminum parts.
